Abstract: 852,702. Electroluminescence. NATIONAL CASH REGISTER CO. Feb. 27, 1958 [March 7, 1957], No. 6344/58. Class 39(1). [Also in Group XL(b)] An electrical switching device comprises a plurality of electro-luminescent elements, the state of which depends upon the application of an input potential, and a plurality of photoconductive cells each associated with a corresponding one of the electro-luminescent elements, light generated by one electroluminescent element causing the resistance of the corresponding photo-conductive cell to decrease so that the resistance of the photoconductive cell depends upon the input potentials applied to the electro-luminescent element. In the arrangement illustrated the device comprises a glass base plate 21 having on one surface thereof an electrically conducting transparent layer 22 to which a terminal connection 23 is made and overlying this an electro-luminescent layer 24 which may be of a zinc sulphide copper activated type of phosphor, terminals 25, 26 &c. being formed on the outer surface of the layer 24. Photo-conductive cells 29, 30 &c. comprising either a single crystal of cadmium sulphide or a poly crystalline film are disposed on the reverse side of the base plate 21, each of the photo-conductive cells being associated with a corresponding electroluminescent element formed by the portion of the layer 24 underlying a corresponding one of the terminals 25, 26 &c. The electro-luminescent elements are excited from a transformer 34. The application of input potentials is indicated by the actuation of switches 37, 44 &c., the closing of switch 37 and the opening of switch 44 resulting in the excitation potential being no longer applied between terminal 25 and the layer 22 and terminal 26 and the layer 22 respectively, the electro-luminescent cells ceasing to glow and the photo-conductive cells 29, 30 assuming a high resistance value. The arrangements illustrated include an " AND " gate, and an " AND " gate having one " inhibit" terminal (actuation of which prevents the generation of an output signal), and an " OR " gate.

A control winding 23 of a two-phase servomotor 25 is connected in series with phaseshifting capacitor 29 across resistors 50, 52, in the cathode circuit of a pentode 17. A power amplifier 16, which comprises the pentode, is connected through pre-amplifier 7 to a source 5 of A.C. control signals. The cathode follower circuit has a high negative feedback which prevents hunting, a capacitor 57 providing greater stability of control. A resistor 54, associated with control grid 35, permits the pentode 17 to operate over a wide range of signals. In another arrangement, the control signal is derived from the rotor winding of a synchro receiver which is coupled with a synchro transmitter. The rotor of the receiver is coupled to the servomotor and is adjusted to provide zero output when the transmitter and receiver are in correspondence. Control signals above a predetermined value are attenuated by a circuit comprising a pair of oppositely-poled diodes. Both the pre-amplifier and power amplifier comprise transistors, the control winding of the motor being connected as an emitter follower, Fig. 2 (not shown).

Title: Improvements in or relating to fuel injection apparatus
IPC: F02M59/00
Filed: 1941-05-21
Abstract: 549,527. Fuel-injection pumps and valves. JOHNSTON, J. May 21, 1941, No. 6535. [Class 102 (i)] [Also in Group XXVII] Fuel-injection apparatus comprises an inertia lever 18 which is rocked against the action of a loading spring 27 and which is articulated at 16, 17 to a pump plunger 10 and to the stem 11 of a fuel admission valve 15. As shown, the cylinders of the plunger and valve stem are parallel and connected by a passage 20 containing a spring-controlled non-return valve, whilst the lever 18 is weighted as at 40 and is rocked by a spiral cam 39. The spring 27 is loaded between blocks 41, 42, anti-friction balls 143, 144, and arms 28, 29 carried by the pump body 12 and a housing 30. The latter has lugs 31 mounted on the pivot 17 and contains a spindle 33 which is rotatable by a crank-arm 35 and carries a spiral cam 34 which adjustably engages the lever 18 with an approximately point contact normally intermediate the pivots 16, 17. When the lever 18 is released by the cam 39 it is rotated about pivot 17 by the spring 27 and the plunger 10 is forced downwards until it is temporarily checked due to compression of the fuel in the passage 20. Due to its inertia, the lever 18 continues to move and rocks about the pivot 16 to lift the valve 11. This permits fuel to escape through the orifice 14 and the spring 27 again forces the plunger downwardly to expel the charge of fuel before the valve 15 is reseated. In one modification, the spindle 33 and cam 34 are replaced by a simple slide which traverses lengthwise of the lever 18, whilst in a second modification the spring 27 is situated centrally with respect to the plunger 10 and valve stem 11 on that side of the lever 18 which is remote from the plunger and valve stem, and the lever 18 is extended beyond the valve stem for engagement with a cam such as 39.

Abstract: 525,758. Electron multipliers and circuits therefor. KOLSTER-BRANDES, Ltd., BEATTY, W. A., and CHATTERJEA, P. K. Feb. 28, 1939, No. 6553. [Classes 39 (i) and 40 (v)] An electron-multiplier with one or more secondary-emitting electrodes has at least two non-emitting collecting electrodes one of which is used only for feeding back alternating current to an earlier part of the apparatus. The feedback may be positive or negative depending upon the frequency and the time-characteristic of the multiplier. The collecting electrodes may be made non-emitting by special treatment of the surface, e.g. carbonizing, or by arrangement in such a position that any secondary electrons emitted do not contribute to the multiplying action. As shown, a collecting electrode A<SP>1</SP> is arranged to collect some of the electrons from the secondary-emitting electrode SE<SP>2</SP> and is connected through an impedance ZA<SP>1</SP> to the biassing potentiometer R<SP>1</SP>, the voltage across the impedance being fed back over a variable impedance FB to the circuit of the control grid 12 (either to a cathode resistance R<SP>2</SP> or a grid impedance ZG). In modifications, the feed-back may be taken across part only of impedance ZA<SP>1</SP>, impedance FB may be omitted and ZA<SP>1</SP> made variable. ZA<SP>1</SP> may be connected in series in the grid-cathode circuit, or the feed-back may be to an earlier secondary-emitting electrode. Specification 495,839 is referred to.

Abstract: 1390611 Boots &c BRITISH UNITED SHOE MACHINERY CO Ltd 10 March 1972 [11 March 1971] 6564/71 Heading A3B Machines and methods are described and claimed in which shoes are side-lasted using a single gripper and two progressive wipers. In one method, applicable when the shoe has been pulled-over, heel-seat lasted and toelasted (as Fig. 1), one side of the upper U is tensioned about the last L by a gripper 7 whose jaws 169 act just heelward of the joint and the marginal portions are progressively wiped in over the insole I by a conical, helically ribbed wiper 9 which wipes from the heel end as far as gripper jaws 169 and is then withdrawn. A second cylindrical or slightly tapered wiper 11 now wipes from the toe end as far as the jaws 169 which are then removed allowing wiper 11 to continue heelwards and overlap those margins wiped by wiper 9. Shoes which have not been previously heelseat lasted may be side-lasted by this method if the lasting margins at the sides of the heel portions are suitably deflected under the wipers. The shoe is passed to a similar machine to be lasted on the other side, adhesive being dispensed between the insole and the upper before each lasting operation.
