Title: Piston-cooling devices for reciprocating-piston internal combustion engines
IPC: F01M1/08
Filed: 1970-11-06
Abstract: 1313156 Cooling pistons KLOCKNERHUMBOLDT-DEUTZ AG 6 Nov 1970 [7 Nov 1969] 53004/70 Heading F2T Cooling means for an internal combustion engine piston 1 comprises a nozzle 4 which, when the engine is in operation, is capable of delivering a jet 14 of cooling oil to the piston which jet of oil may be interrupted, or diverted away from the piston, when piston cooling is not required. In the embodiment shown in Fig. 1, the nozzle 4 is force-fitted in a bore in the engine casing 3 and additionally secured by a metal cup 7. A threaded bore 10 closed by a screw 8 permits insertion of the nozzle which extends into a duct 11 through which pressurized oil may be supplied to the nozzle. The oil jets 14 may be directed into a duct 6 and thus circulate through a cooling duct 15 in the piston head or, if the duct 6 is omitted, it may be projected against the underside of the piston. The oil supply to the nozzle 4 may be shut off when required by a plug 16, Fig. 3, which projects into the nozzle bore and is located by a screw 18. In a further modification, Figs. 5 and 6, the nozzle 4 threadedly engages the casing bore at 24 and forms part of a bolt 20 having a slotted head 21. When the slot is in the position shown in Fig. 6 the jet 14 acts as a coolant but when the body 20 is rotated through 90 degrees the jet impinges against a wall of the casing. A screw 22 engages a groove 23 in the head 21 to lock the body 20 in one or other position, the direction of the slot serving as an index mark.

Filed: 1973-12-03
Abstract: 1452757 Frequency detectors TEXAS INSTRUMENTS Ltd 3 Dec 1973 56011/73 Heading H3A A frequency detector comprises two transistor switches which connect a storage capacitor to one or other of two current sources for times dependent on the frequency of the input signal such that a residual voltage is stored on the capacitor when the input signal frequency traverses a threshold value, each of the current sources comprising a pair of like conductivity transistors respectively. In one embodiment, Fig. 2, monostable A is triggered by the incoming signal to provide output pulses which turn on transistors T1, T2, T10 and turn off transistor T9. Capacitor C now charges from the current provided by current mirrors T3, T4 and T5, T6. During the space between pulses T1, T2, T10 turn off, turning off current mirror T3, T4, and T9 turns on to allow capacitor C to discharge through transistor T8. When the input frequency exceeds a predetermined threshold, the voltage across capacitor C builds up sufficiently to energize an output detector. A hysterisis circuit, Fig. 4 (not shown), may be interposed between the output 8 and the detector to obviate false operation by the charging/ discharging waveform across the capacitor. In another embodiment, Fig. 3 (not shown), only a single current mirror (T12, T13) is provided for charging the capacitor. The arrangement is used for controlling fuel to an engine in dependence on engine speed.
