Office Action

§112
Detailed Action Notice of Pre-AIA or AIA Status The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Drawings The drawings are objected to under 37 CFR 1.83(a). The drawings must show every feature of the invention specified in the claims. Therefore, the “filter hole” in claim 2, the “plate lug” and “bolt” and “locating slot” in claim 3 and the “limit slot” in claim 6 must be shown and numerically labeled in the drawings/specification or the feature(s) canceled from the claim(s). No new matter should be entered. Corrected drawing sheets in compliance with 37 CFR 1.121(d) are required in reply to the Office action to avoid abandonment of the application. Any amended replacement drawing sheet should include all of the figures appearing on the immediate prior version of the sheet, even if only one figure is being amended. The figure or figure number of an amended drawing should not be labeled as “amended.” If a drawing figure is to be canceled, the appropriate figure must be removed from the replacement sheet, and where necessary, the remaining figures must be renumbered and appropriate changes made to the brief description of the several views of the drawings for consistency. Additional replacement sheets may be necessary to show the renumbering of the remaining figures. Each drawing sheet submitted after the filing date of an application must be labeled in the top margin as either “Replacement Sheet” or “New Sheet” pursuant to 37 CFR 1.121(d). If the changes are not accepted by the examiner, the applicant will be notified and informed of any required corrective action in the next Office action. The objection to the drawings will not be held in abeyance. Specification The title of the invention is not descriptive. A new title is required that is clearly indicative of the invention to which the claims are directed. The following title is suggested: CIRCULATING WATER PUMP INLET PIPE WITH VALVE AND CLEANING COMPONENTS FOR DATA CENTER COMPUTER ROOM Claim Rejections - 35 USC § 112 The following is a quotation of 35 U.S.C. 112(b): (b) CONCLUSION.—The specification shall conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention. Claim 1 and its dependents are rejected under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), second paragraph, as being indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor or a joint inventor (or for applications subject to pre-AIA 35 U.S.C. 112, the applicant), regards as the invention. As the list of indefinite and/or unclear phrasings is long, Examiner proposes the following revised claims to begin a suggested remedy in the claim language (claims 2, 6 and 8 don’t appear to require any changes): 1: A circulating water pump for a data center computer room, comprising a circulating water pump main body (1), a water inlet pipe (2) and a water outlet pipe (3) being respectively arranged on a left side and a right side below the circulating water pump main body (1), wherein an end of the water inlet pipe (2) is fixedly connected to a connecting pipe (4), a cleaning pipe component I (5) and a cleaning pipe component II (6) are arranged on the connecting pipe (4), the cleaning pipe component I (5) and the cleaning pipe component II (6) have a same structure, a respective electric butterfly valve (8) is fixedly installed at an end of the cleaning pipe component I (5) and at an end of the cleaning pipe component II (6) away from the water inlet pipe (2), a respective cleaning component (9) is arranged inside an end of the cleaning pipe component I (5) and inside an end of the cleaning pipe component II (6) close to the water inlet pipe (2), a respective blow off pipe (10) positioned between the respective electric butterfly valve (8) and the respective cleaning component (9) is fixedly installed at a bottom of the cleaning pipe component I (5) and at a bottom of the cleaning pipe component II (6), and a bottom end of each blow off pipe (10) is fixedly connected to a respective blowdown solenoid valve (11); each cleaning component (9) comprises a front-end filter plate (91), a rear-end filter plate (92), a transmission shaft (93), a transmission turbine (94), two rotary scrubbing mechanisms (95), and two vibration cleaning mechanism 3. The circulating water pump for the data center computer room according to claim 2, wherein a plate lug is provided on a periphery of the front-end filter plate (91) and a plate lug is provided on a periphery of the rear-end filter plate (92), and inside each of the cleaning pipe component I (5) and the cleaning pipe component II (6) there are respectively provided locating slots into which the respective plate lugs fit, and a respective plate lug bolt is threaded through an inside of each plate lug and has a threaded connection with one of the cleaning pipe component I (5) and the cleaning pipe component II (6). 4. The circulating water pump for the data center computer room according to claim 3, wherein each cleaning component (9) further comprises a mounting rack (97), the mounting rack (97) clamped at another end of one of the cleaning pipe component I (5) and the cleaning pipe component II (6), the transmission shaft (93) is movably sleeved in a middle of the mounting rack (97), and the transmission shaft (93) is sleeved in a middle of the front-end filter plate (91) and in a middle of the rear-end filter plate (92). 5. The circulating water pump for the data center computer room according to claim 4, wherein each rotary scrubbing mechanism (95) comprises a central sleeve (951), a plurality of cleaning arms (952), cleaning bristles (953), a locating ring (954), a compression spring (955), and a limit block (956); the central sleeve (951) is movably sleeved on an outside of the transmission shaft (93), the plurality of cleaning arms (952) are arranged on a periphery of the central sleeve (951), and one side of each of the plurality of cleaning arms (952) is provided with the cleaning bristles (953). 7. The circulating water pump for the data center computer room according to claim 6, wherein each vibration cleaning mechanism (96) comprises a locating cantilever (961), a guide rod (962), a top pressure rod (963), a drive slider (964), and a reset spring (965); the locating cantilever (961) is fixedly connected to the plate lug of the front-end filter plate (91) or the plate lug of the rear-end filter plate (92) by the respective plate lug bolt, an end of the locating cantilever (961) is movably provided with the guide rod (962) fixedly connected to the top pressure rod (963), the reset spring (965) is movably sleeved on an outside of the guide rod (962), the drive slider (964) is fixedly installed on the outside of the transmission shaft (93), and the drive slider (964) is provided with an oblique plane fitting to the top pressure rod (963). 9. The circulating water pump for the data center computer room according to claim 8, wherein the flow meter (7), each electric butterfly valve (8), and each blowdown solenoid valve (11) are all electrically connected to the PLC controller (12), the PLC controller (12) is configured to control on/off of each electric butterfly valve (8) and of each blowdown solenoid valve (11), and the PLC controller (12) is further configured to receive detection data of each blowdown solenoid valve (11). Allowable Subject Matter Claims 1-9 would be allowable if rewritten or amended to overcome the rejection(s) under 35 U.S.C. 112(b) or 35 U.S.C. 112 (pre-AIA ), 2nd paragraph, set forth in this Office action.
