Title: Call holding circuits
IPC: H04M3/58
Filed: 1970-12-18
Abstract: 1328836 Automatic exchange systems WESTERN ELECTRIC CO Inc 18 Dec 1970 [18 Dec 1969] 60225/70 Headings H3T and H4K A call holding circuit which on actuation places a hold condition on a telephone line responds to the sequence of on-hook followed by off-hook condition removing the hold condition. As shown the call holding circuit 5 is located at a substation or is common to a group of stations sharing a line and enables a subscriber involved in a call using a main telephone 1 to actuate a key 26 at his substation to bring the circuit 5 into operation, then to replace his receiver and on lifting the receiver at an extension telephone 2 to continue the call, the call holding circuit maintaining the line loop during the interim period. Closing of the key 26 momentarily pulses the gate electrode of a PNPN transistor 9 switching it to conduction looping the line and causing capacitors C25 and C28 to charge to the voltages developed across resistors R24 and R27. Replacement of the receiver at station 1 removes the line loop in parallel with the call holding circuit. The consequential potential drop increase across the call holding circuit further charges the capacitor 25. When the extension or main station receiver is lifted to continue the call the consequential potential drop across the call holding circuit partially discharges the capacitor 25. The discharging of capacitor 25 reduces the current through transistor 19 to a level at which it switches to its low conductive state, releasing the hold circuit. The call then continues in the normal manner.

Title: Distributing valve system for air-starting i.c. engines
IPC: F02N9/04
Filed: 1979-09-28
Abstract: An annular support 1 surrounding the engine camshaft has a plurality of identical chambers 3 receiving slide valves 5 which control the supply of pressure medium through passage 12 to the starting- air valves. The slide valves 5 are operated in synchronism with the engine upon the opening and closing of discharge ducts 18 connected with chambers 16 formed in the slide valves and communicating with the pressure medium supply passage 11. The discharge ducts 18 are formed in an annular cover 17 mounted on the support 1 with their outlet ends adjacent the path of the cam 19 on the camshaft. As the outlet end of each duct is closed, in turn, by the cam, the pressure in chamber 16 increases and the valve 5 moves to the right, in Fig. 1, so that pressure air passes through passage 12 to the starting-air valves of the engine. The apparatus is useful for engines with differing numbers of cylinders, the appropriate number of slide valves and discharge ducts being provided to correspond to the number of starting-air valves and any remaining chambers being left vacant. The apparatus does not require a long camshaft with separate cams for each slide valve. <IMAGE>
