IPC: F01K15/04
Filed: 1956-06-15
Abstract: 862,563. Valves. FAIRFIELD SHIPBUILDING & ENGINEERING CO. Ltd. June 14, 1957 [June 15, 1956], No. 18572/56. Class 135. [Also in Group XXVI] A fuel valve 43 is actuated by a device 61 when the pressure in the chamber 73 falls below a predetermined value. The control valve 43 comprises a valve proper 64 carried by a stem 65 which has a hand wheel 66 and a screw-threaded portion 67 for hand operation and is lightly urged by a spring 68 to close against the seat 63. A nut 69, held against turning by a guide 70, is movable with the stem. A lever 77 pivoted onthe nut 69 and engaging a stop 79 is connected to a spring-loaded piston 74 of the device 61. When the pressure in the chamber 73 falls below a predetermined value, the spring 75 forces the piston 74 downwards and pulls the lever 77 away from the stop 79 and against the fulcrum 81. This releases the nut 69. The spring 75 then acts through the lever 77 to shut the valve and is assisted by the fuel pressure on the valve proper. The valve 43 must be re-set by operation of the hand wheel 66.

Abstract: 1,106,073. Fluid actuation of switches. TECALEMIT (ENGINEERING) Ltd. 4 May, 1965 [5 May, 1964], No. 18660/64. Heading H1N. A valve and switch unit primarily intended to function as a combined oil pressure relief valve and low pressure warning light switch in an internal combustion engine comprises a metal cylinder 1 housing a fixed contact 8 mounted in a metal block 4 and moving contact 7 mounted in an insulating piston 6 and connected by lead 9 and rivets 10 to a terminal 12, the contacts being urged into engagement by spring 13. When the engine ignition is switched on a circuit is completed through the contacts to energize a warning light which remains alight until the engine has been started and the resultant oil pressure is sufficient to operate piston 6 against the pressure of spring 13 to break the contacts. A drop in oil pressure will cause the warning lamp to light. Excess oil pressure will cause piston 6 to uncover outlet ports 14. The pressure at which outlet ports 14 are uncovered is determined by the combined pressure of springs 13 and 15, the latter of which is engaged after the contacts have been broken. In a modification, spring 13 may provide the electrical connection between contact 7 and rivets 10.

[Classes 83 (ii) and 83 (iv)] Angular bending; dies.-A method of making a shackle comprises electrically up-setting heads on each end of a straight blank, pressing them to the shape of the desired eyes, electrically heating the centre portion only of the blank and bending the heated blank to U-shape by pressing it into a U- shaped die. Each end of a bar is electrically upset and pressed to form eyes 11, 12 and the centre portion 20 is then electrically heated by means of vice electrodes 15, 16 and 17, 18 connected to the secondary winding 19 of a step-down transformer. The blank is then placed horizontally between guides 30, 31 on a die block 21 and is pressed to U-shape by means of a plunger 34. The die block has a central opening 22 lined with plates 24, 25 having vertical slots 28 to receive the shank 20 of the shackle and also to support the lower sides of the enlarged eye portions so that they are correctly positioned relatively to one another in the completed shackle.

In a camera having a coupled exposure meter and a non-rotatable bayonet mount on the exposure objective for receiving optical accessories such as filters, to take account of the effect on the brightness of the exposure beam produced by attachment of the accessory, the objective bayonet fitting is formed with recesses engageable by the bayonet lugs on the accessory, which lugs also fit into notches in a ring rotatable coaxially of the objective and coupled to the exposure meter, so that by rotating the accessory by an appropriate amount during its attachment the required change in the exposure valve employed may be effected. As shown, the taking lens :of a twin lens camera is provided with a fixed bayonet mount 4 having recesses 9 and disposed rotatably within it a ring 20 having notches 21 aligned with the recesses in the idle position. When the bayonets lugs 8 of a mounting ring 7 of an accessory such as a colour filter are inserted into the recesses 9 and the ring is turned to secure it on the objective the ring 20 is turned also and by means of a pin-and-slot connection 25, 26 a ring 24 rotatably mounted on the viewfinder objective moves the spindle 28 along the direction A-B and so adjusts the position of the pointer of a photo-electric meter 33. To facilitate the adjustment the mounting ring 7 bears an exposure factor number 22 and attached to the ring 20 is a disc 36 bearing a scale 37 of exposure factors visible through a window 38 in the front wall of the camera. To make allowances for film speed, a setting disc 32 on a shaft 31 aligned with the pivot pin 35 carrying the collar supporting the shaft 28 is rotated to transmit via pinions 29, 34, 30 a movement to the meter pointer.

Filed: 1975-05-06
Abstract: 1511343 Data transmission AVANTEK Inc 6 May 1975 [7 May 1974] 19013/75 Heading H4P In a digital data transmitting system, two independently timed, i.e. asynchronous, binary data streams Channel A and Channel B are applied to respective encoders 1 and 3. Each channel of data undergoes signal processing consisting of timing extraction, differential encoding and, optionally, scrambling; additionally, the data rate of Channel A is increased slightly by circuitry 5 including a frequency translation loop, so that Channel A data is distinguished from the Channel B data. In each encoder the data is first changed from bipolar to return-to-zero format, the latter signal then driving a ringing filter which selectively extracts the clock frequency from the input signal spectrum; the filter output is then fed to a phaselocked loop which generates a reconstructed clock signal driving a flip-flop converting the return-tozero format to non-return-to-zero format for optional processing by the scrambler 2 or 4 in which scrambling is effected by modulo-two summing with an internally generated pseudonoise sequence. The encoder outputs are applied to a quadriphase modulator 10 providing a four phase signal on line 24 for transmission, by way of an amplifier 26, over a transmission medium 28. The received signal is processed by a demodulator 34 and then fed to a circuit 64 which recognizes the increased data rate of Channel A and which provides outputs to other circuitry whereby signals corresponding to the original data signals are produced on output lines 66 and 68. Suitable arrangements for the encoders, modulator and receiving circuits are described with reference to Figs. 2 to 12 (not shown).

[Class 38(v)] A thermally-actuated device for protecting a three-phase motor operates more quickly on the occurrence of an open phase than on a balanced overload.

On a balanced overload the bars 3, 4 keep parallel to the base 8 as they are moved upwards to engage a member 5 and separate trip contacts 6, 7. On open phase, the bar or bars connected to the bimetal strip of that phase tilt about that strip since it remains unflexed, and consequently the ends of the bars 3, 4 are moved through a greater dis-- tance than the ends of the flexed strips which move them, and the contacts 6, 7 are operated sooner. U-shaped spiral, and helical strips also are referred to..
