Title: Battery powered automatic calendar
IPC: G09D3/12
Filed: 1975-10-31
Abstract: 1471836 Date indicators G E DUNNING 31 Oct 1975 [16 May 1975] 20798/75 Heading G3T In an indicator displaying date numerals and month names and operated by a solenoid 11 which acts repeatedly at the end of a short month to avoid the display of unwanted dates, the solenoid is controlled by a first circuit comprising a switch 20 which is closed once a day by a clock 21 or other timer, and a second circuit which comprises a normally closed switch 25 and contacts so coupled to the display that this circuit can be closed only when an unwanted date is displayed, the plunger 13 of the solenoid being arranged to open the switches 20, 25 at the end of its stroke and to reclose the switch 25 when it returns to its rest position. The solenoid is thus energized only briefly and can be powered by dry cells 18 which can also drive the clock. As described the second circuit comprises rotary switches 26, 27 respectively coupled to the date display shaft (6), Fig. 2 (not shown) and the month display shaft (8) which is advanced by one twelfth of a turn for each revolution of shaft (6). The switch 27 has two sets of contacts 33, 34, the February contact 34 only being used and the contacts 33 corresponding to short months all being connected to the 31st day contact of switch 26. At midnight, clock 21 closes the switch 20, energizing solenoid 11 to draw in plunger 13. The switches 20, 25 are thereby opened so that the plunger immediately returns to its rest position, advancing the date display and the switch 26 and reclosing switch 25. In a long month, switch 27 is open so that the reclosure of 25 has no effect until arm 28 of the switch 26 reaches a contact 31c corresponding to several blank days of the date display. The reclosure of 25 then repeatedly re-energizes the solenoid to step the display to the first day of the next month. At the end of a short month, switch 27 is closed so that reclosure of 25 causes repeated stepping of the display as before as soon as arm 28 reaches one of contacts 31b. Contacts 41, 42 allow the circuit to be set by hand for a leap year, contact 40 then being left open.

Filed: 1975-05-19
Abstract: 1485560 Turbine stop gear WESTINGHOUSE ELECTRIC CORP 19 May 1975 [6 June 1974] 21152/75 Headings F1K and F1T An electro-hydraulic emergency trip system 11, Fig. 1, for rapidly closing the steam valves, e.g. throttle valves TV1-TV4, governor valves GV1- GV8, re-heat stop-valves SV, and interceptor valves IV, of a turbine power-plant 10 in response to predetermined contingencies,comprises an hydraulic system, Fig. 2, including first and second sets of hydraulic valves AST1, AST3 and AST2, AST4 controlled by solenoid pilot valves 101, 103 and 102, 104 receiving signals from an electrical system, Fig. 6, in response to a signal from a detector system, e.g. low bearing oil detector system 13, thrust bearing detector system 14, overspeed detector system 15, low condenser vacuum detector system 16, a remote detector system 17 for unit transformer failure, or low actuating oil pressure detector system 18, the valves being arranged such that the emergency trip system is only effective to close the steam valves if at least one valve from both sets AST1, AST3 and AST2, AST4 are opened. In this manner, malfunction of a single component in the system is ineffective to actuate the system. Also, Fig. 8, the components may be individually tested without actuating the system, and whilst maintaining it able to respond to a signal from one of the detector systems to actuate the trip system. The valves AST1-AST4 act to drain hydraulic pressure from the actuating devices 52-55 of the steam valves to close the valves when a signal is received by the pilot valves from the detector system. In Fig. 1, for example, the low-pressure-detector system 18 includes a pair of low-pressure sensors LPS(A), LPS(B), which close contacts 261, 262 in the electric system of Fig. 6, when the pressure in the system falls below a predetermined value. Closure of the contact 261, 262 is effective to de-activate relays LP(A), LP(B)  opening their contacts 218, 227 causing trips Al, A2 and B1, B2 to de-activate the solenoids of valves AST1-AST4 to open these valves. The other detector systems act similarly. Each detector system also includes simulation devices, e.g. valves LPT(A), LPT(B) in the low oil pressure detector system 18 individually controlled by the testing circuit, Fig. 8, to allow testing of the components by simulating a low-pressure situation. In Fig. 8, two independent A.C. sources are used, each of which is sufficient on its own. The trip system is suspended at starting. The testing circuit of Fig. 8 may be computer controlled. The system is reset after actuation by latch 269, Fig. 6, by depression of push button 275.
