Title: Apparatus for detecting a change from a given line frequency and/or power factor in an ac power supply/load combination
IPC: H02H3/42
Filed: 1974-11-29
Abstract: 1492565 Monitoring frequency and power factor XEROX CORP 29 Nov 1974 [26 Dec 1973] 51800/74 Heading H2K To detect change in the frequency or power factor of an A.C. power supply from given values, a pulse train C<SP>1</SP> is derived having one logic state at instants when the voltage and current waveforms have the same polarities and the other state when they have opposite polarities, and an alarm given if the length of a pulse in the train exceeds a predetermined amount. The pulse train C<SP>1</SP> is derived by multiplying together square waves A, B in phase with the voltage and current respectively and produced by output-limited amplifiers 10, 20. The leading edge of each pulse in the pulse train C<SP>1</SP> triggers a monostable 40 and an alarm output produced only if the monostable resets before the end of the pulse. The arrangement may be used to detect failure of a computer power supply and initiate immediate transfer of volatile data to a non-volatile storage medium.

Title: Mixer for hot and cold liquids
IPC: F16K11/18
Filed: 1974-12-04
Abstract: 1433660 Valves KUGLER FONDERIE et ROBINETTERIE SA 4 Dec 1974 [11 Dec 1973 20 Nov 1974] 52543/74 Heading F2V In a hot and cold water mixing valve rotation of an actuating handle 56 about trunnions 59 causes a cam 64 to act on a non-rotatable member 65 to move an abutment 67 thereon, which abutment pivots an actuating member 37a about an axis B on journals 35. Operating members 45 attached to valve stems 16, 19 are thus moved to adjust the total delivery flow through the inlet ducts 2 into the mixing chamber 6 which has an outlet 4. Rotation of the handle 56 about the axis H-H causes the member 37a to rotate relative the flat plate 40 on which the abutment 67 and the ends 47 of the valve stem operating members abut so that the distances from the pivot axis B of the member 37a to these points of abutment are altered to vary the ratio of hot and cold water and thus the mixture temperature. The adjustments for temperature and flow are thus independent. The valve members 11 are fluid pressure balanced and are loaded by springs 18 which maintain the ends 47 of the operating members 45 and the abutment 67 in contact with the flat plate 40.

IPC: G05D16/06
Filed: 1968-11-08
Abstract: 1,205,698. Valves. PARKER-HANNIFIN CORP. 8 Nov., 1968, No. 53084/68. Heading F2V. A pressure reducing valve comprises a valve member 29 controlling flow between inlet and outlet passages 11, 12, and responsive to pressure derived from the outlet acting on the diaphragm 47 in a control chamber 57 against a loading spring 53. In order to avoid vibration or hunting, a resultant control pressure is derived by combining two different pressures which enter a pressure combining chamber with a phase difference through separate passage means from the inlet. Pressure is led firstly through relatively unrestricted passage means comprising grooves 24, and an annular chamber 26 round a seat member 34, and secondly from the interior of the seat member through a restricted passage 44, a slit in an insert tube 38, and a slight clearance between a land 23 on the seat member and a bore 15, into the chamber 26 which constitutes the pressure combining chamber. The tube 38 may be used also as a pressure gauge connection, by removing a plug 42. Overpressure at the outlet is vented from the control chamber through a seat 49 carried by the diaphragm. In order to avoid "regulator droop" or drop in pressure between the normal maximum pressure in outlet port 12 and the pressure therein at which flow through the valve is reinstated, a bleed groove (64), Fig. 5 (not shown), is formed in the relief seat 49. This bleed groove may be replaced by a bleed hole to atmosphere directly from the outlet passage 12.
