Filed: 1970-08-14
Abstract: 1322592 Cine cameras NIPPON KOGAKU KK 14 Aug 1970 [18 Aug 1969] 39314/70 Heading G2E A cine camera has means for automatically making lap-dissolve exposures comprising a disc shutter on a shaft 1, driven by reversible motor 5, whose exposure aperture is defined by blades 4, 4' movable between an open and a closed position by axial displacement of a sleeve, 6 on shaft 1, a predetermined length of film being exposed during the closure of the blades, that same length being first rewound and then re-exposed as the blades are opened. Shutter release 42 is depressed to a first position to close switch S2 to start normal photography, and to a second position in which interlock lever 16 is swung against spring 13 to cause disengagement between a worm-gear 8 and a film take-up drive gear 7. Gear 8, however, now moves on lever 11 until the coaxial clutch gear 9 engages and drives a scale gear 18 which advances a predetermined length of film. An eccentric pin 20 on the gear 18 pivots a lever 21 about stud 22, whereby a further pin 25 on the lever displaces a connecting-rod 26 in direction A. Shutter adjusting lever 27 is shifted by rod 26 to displaced sleeve 6 on the shaft 1 and so to close blades 4, 4'. At this point the lower end of lever 21 actuates swich S3 to reverse-wind the said film length, the blades 4, 4' remaining closed due to the slot between pin 25 and rod 26. Subsequent operation of release 42 starts normal exposure, a gear 36. With an eccentric pin 38 being driven by gear 7 so that shutteradjust lever 27 is shifted to the right by the engagement of said pin 38 and a lug 27a. Blades 4, 4' are thus reopened for a fade-in, at the end of which hook 26a on rod 26 releases a gearshift plate 31 to disengage gears 36 and 7.

Abstract: 1346562 Electronic fuel injection for I. C. engines BENDIX CORP 29 Aug 1972 [27 Sept 1971] 40042/72 Heading G1N In an I. C. engine fuel control system of the type having computing means responsive to engine operating parameters to generate a signal to control actuation of fuel injection valve means, a circuit responsive to engine deceleration conditions is provide to inhibit injection of fuel, the circuit including signalling means for generating a signal in response to an operator demand for deceleration, bistable switching means switchable from a first to a second state in response to coincidence of a signal from the signalling means and a signal indicating an engine speed at least equal to a first preset value and operable to remain in the second state while the signal from the signalling means continues and the engine speed exceeds a second preset value which is lower than the first, and means responsive to the bistable switching means being in the second state to generate an inhibiting signal. The system, Fig. 1 and 2 (not shown), is of the intermittent type having a monostable multivibrator triggered in synchronism with engine rotation to provide a first pulse dependent upon intake manifold pressure, and a circuit to provide a second pulse having a duration dependent upon the duration of the first pulse and upon engine temperature, the two pulse being applied sequentially to control actuation of the injection valve means. An r.p.m. correction circuit is also provided to control the voltage applied to the intake manifold pressure transducer in dependence upon engine speed. The fuel cut-off circuit, is shown in Fig.3, the bistable switching circuit being provided by a Schmitt trigger 308, 310 and the signalling means by a throttle switch 38. An input part 214 receives a pulse signal having a constant pulse duration and a frequency dependent upon engine speed. This signal is developed in conjunction with the operation of the monostable multivibrator, Fig.2 (not shown). A resistive, diode and capacitive network 312-318 receives this signal and develops an input voltage to the Schmitt trigger directly related to engine speed. When this voltage exceeds the first preset value and when the throttle switch 38 is closed, the Schmitt trigger switches to its second state thereby initiating an inhibiting signal at output port 302, this signal preventing the injection valve means being actuated. When the engine speed falls to the second preset value determined by a transistor 362, capacitor 368 and a programmable unijunction transistor 370, the Schmitt trigger reverts to its first state thereby removing the inhibiting signal. Similarly, if the switch 38 is opened at any time, or a transmission switch is connected to its park or neutral position, the Schmitt trigger reverts to its first state.

Title: Temperature monitoring means
IPC: H01L35/00
Filed: 1962-10-23
Abstract: 989,655. Photo-electric sensing devices. SOC. D'ELECTRICITE MORS. Oct. 23, 1962 [Oct. 23, 1961], No. 40078/62. Heading G1A. [Also in Divisions G4, H1 and H3] A number of thermocouples are series connected to provide a monitoring system for a room. The output is applied to a D.C. chopper amplifier (see Division H3) the output V of which is, in turn connected to terminals 1, 2 of the alarm circuit of Fig. 6. If input voltage V is lower than the threshold voltage of the Zener diode Z1 indicating a normal temperature transistors TR1, TR3 and TR2, TR4, TR5 are biased into conduction and non-conduction respectively. Should the temperature rise abnormally, the input V becomes greater than the Zener diode threshold voltage, the transistors switch to their other states and lamp L and hooter K are energized. In order to ensure that they remain energized even though voltage V drops again, a photo-sensitive resistor PR is energized on lighting the lamp L and provides a negative bias to the base of TR4 which thus remains conductive until an acknowledgment switch I is pressed to apply a positive bias to the base of TR4 to turn it off. The threshold of A1 may be adjusted by potentiometer P1 and diode D prevents the disturbance of input voltage V by the base current of TR1 when V is below the Zener threshold value. In another embodiment (Fig. 7, not shown) the alarm signal is operated when the voltage V falls below a prescribed minimum. Figs. 9, 10 (not shown) illustrate systems for cylically monitoring a plurality of sensing elements. Photo-cell and lamp circuit (Fig. 8). The photosensitive resistance PR and lamp L are secured in a position 10, light from a light guide 12 being emitted from aperture 17.

Abstract: 1,060,969. Aircraft instruments. SAFE FLIGHT INSTRUMENT CORPORATION. Oct. 2, 1964 [Oct. 16, 1963], No. 40288/64. Heading B7W. [Also in Division Gl] In a device for producing an output signal to indicate an undesirable diminution of headwind during an aircraft's landing approach, or to control automatic apparatus to initiate corrective action, a signal indicative of the airspeed or lift of the craft is modified by a signal indicative of forward deceleration of the craft, although positive forward acceleration has no effect on the output signal. As shown, Fig. 1, an air-speed transducer 12 positions the wiper 68 of a D.C.-energized potentiometer 64 to pick off a potential which is compared with that of the wiper 76 of a reference potentiometer 72 in a first control winding 106 of a magnetic amplifier 20. Forward acceleration is sensed by a pendulum device 18 which positions the wiper 94 of a potentiometer 90; pitch is compensated by a vertical-gyro senser 16 controlling the wiper 86 of a potentiometer 82. Signals indicative of deceleration pass through a second control winding 108 of magnetic amplifier 20, but signals indicative of positive acceleration are shunted through a diode 112 and a series resistor 113. The output signal 104 from the magnetic amplifier is amplified at 114 and fed to indicating or control means 22. Fig. 2 (not shown) depicts a lift senser comprising an angle-ofattack vane controlling a potentiometer to produce a signal which may replace the signal indicative of air-speed. The system may be wholly mechanical.
