Patent GB-1089120-A (GB)
Title: Shaft encoder
IPC: H03M1/00
Filed: 1965-11-30
Abstract: 1,089,120. Digital shaft encoders. LITTON INDUSTRIES Inc. Nov. 30, 1965 [Jan. 4, 1964 (2)], No. 15241/67. Divided out of 1,089,119. Heading G4H. A digital shaft encoder has a commutator having a plurality of discrete conducting and non-conducting segments within each of a number of annular zones, one for each digit, there being a number of redundant contact locations defined by the position of a set of interconnected contacts for each zone, certain of the zones being divided into a number of sub-zones and both the corresponding segments of the sub-zones and the contact locations being displaced in the direction of movement of the commutator. The commutator is read by the V-scan method, a single reading being obtained from the least significant zone 0, Fig. 3, and lead and lag readings from all the other zones, one of which is selected according to the reading of the next lower digit. Three contacts are provided for each reading in case one or more contacts becomes defective. In the lowest zone 0 three are in corresponding positions spaced four pitches apart. In zone 1 they are spaced by two pitches and in zones 2 and 3 they are in adjacent pitches. This would be inconvenient in zones 4, 5 and 6 and these zones are accordingly divided into annular sub-zones, e.g. 4a, 4b and 4c, displaced relatively to each other so that the contacts can be placed in the same position in the corresponding pitch but at a convenient distance apart. The contacts of each group are interconnected and connected to output terminals.

Title: Improvements in or relating to automatic starting systems for engine driven electric alternating current generators
Inventor: TAYLOR HARRY FREDERICK WOODWAR
IPC: F02N11/08
Filed: 1949-06-14
Abstract: 683,125. Electric supply systems. LISTER & CO., Ltd., R. A. June 14, 1950 [June 14, 1949], No. 15869/49. Class 38 (iv). Automatic starting and stopping of alternating current generating plant in accordance with the closure and opening of its load circuit is controlled by a load relay having two windings arranged on separate iron circuits, one winding detecting closure of the load circuit and effecting closure of the relay to start up the plant, and the other winding being connected in series with the load circuit and holding the relay closed after the first winding has been deenergized-which occurs when the prime mover reaches speed-until the load circuit is interrupted. In the system shown, closure of the load circuit 86 of an A.C. generator 10 completes an energizing circuit (from a battery 13) for the detection coil 63 of a load relay 64, the contacts 24 of which close to energize a contactor 66, thereby connecting the load circuit to the machine 10, over contact 21 and energizing a starting contactor 18 and fuel cut-off solenoid 27, over contact 67. Contactor 18 closes a circuit (at contact 34) for the starting motor 12 of the prime mover, fuel supply to which is now permitted by the solenoid 27. When the prime-mover reaches speed, governor-controlled contacts 69 close and a cut-off relay 28 is energized. Relay contacts 61 open to interrupt the circuit of the detection coil 63 and contacts 70 close to allow recharging of the battery 13 by the machine 12 which is now working as a generator. Machine 10 is also generating, so that load current through coil 65 maintains the load relay 64 energized. Contacts 31 are also opened by the cut-off relay 28, thereby deenergizing starting contactor 18 and so disconnecting the series field 68 of machine 12 at contacts 34. Upon cessation of the load, coil 65 of the load relay is de-energized, contacts 24 open in consequence and restore the starting circuit to its initial condition, de-energization of the fuel cut-off solenoid 27 causing the prime mover to come to rest. To protect the battery in case of engine failure a thermal delay switch 41, 84 energizes a circuit breaker 40 after a predetermined starting time to open the starting circuit at contacts 42 and the detection circuit at contacts 62. Specification 618,877 is referred to.

Title: Improvements in or relating to valves automatically operable to prevent excessive flow of gases
IPC: F16K17/30
Filed: 1952-06-24
Abstract: 700,449. Fluid-actuated valves. PHILIPS ELECTRICAL INDUSTRIES Ltd. June 24, 1952 [June 27, 1951], No. 15883/52. Class 135 A valve, automatically operable to prevent an excessive flow of a gas, comprises a duct 6 normally providing an unobstructed passage between two chambers and a second duct 7 which joins the first duct at an acute angle and which houses a ball 9 held therein by a spring-pressed detent 10. On the occurrence of an excessive pressure difference between the two chambers, ball 9 is forced past abutment 10 and into the dotted-line position in which it cuts off all flow between the chambers. To reset the valve, it is pushed to the top of the duct 6 by means of a pin and it can then roll down a groove 15 in the valve block and so back into duct 7. The valve may be used to control communication between two chambers in an electron microscope.

Title: Improvements in or relating to radiating antenna arrangements
IPC: H01Q1/02
Filed: 1931-06-01
Abstract: 370,247. Aerials. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Marconi House, Strand, London.-(Assignees of Lindenblad, N. E.; Port Jefferson, Long Island, New York, U.S.A.) June 1, 1931, No. 15991. Convention date, June 23, 1930. [Class 40 (v).] An aerial array is constructed so that sleetmelting current can be applied without impairing the directive characteristic of the radiated field. As shown in Fig. 3, the feed wires F supplying an aerial A and its associated reflector R terminate in Y-shaped members N, the radiation from which is balanced by similar members N at the far end. The radiation circuit is closed by a quarter-wavelength loop L in which the high-frequency currents are in phase opposition ; since the loop has substantially infinite impedance, the aerial is practically open-circuited for radio-frequency currents and may be grounded at the nodal point 14. Sleet-melting current is supplied from a source 16 through chokes 18. Fig. 4 shows a preferred modification in which sleet-melting current is supplied to the entire system, including the neutralizing members, corresponding to those marked N in Fig. 3. Radio-frequency energy is supplied through leads 22, 24, and heating- current at nodal points 12 through leads 20 and chokes 18. The feed wires are parallelled and bent at each end, as shown, to prevent radiation. In another modification, Fig. 6, each radiator 2 comprises two conductors 21, 41 which by virtue of the shunt condensers 84 are effectively in parallel across the highfrequency supply T, but are in series through the bridging wire 101 to the heating-currents supplied across a condenser 88 from a source 96. Specification 308,664, [Class 40 (v), Wireless signalling &c.], is referred to.

Title: Improvements in or relating to braiding machines
IPC: D04C3/00
Filed: 1921-06-11
Abstract: 185,843. Wade, H., (Dreifuss, Geb.). June 11, 1921. Braiding - machines. -In a machine of the kind in which a grooved top-plate is dispensed with the continuously - moving bobbin carriers are guided by fixed centre discs 9 and are taken round the machine by rotary sleeves 3 mounted on tubular axles and carrying intermeshing gear-wheels 4. Above each wheel 4 is a conical surface 19 carrying pairs of projections 20 between which are mounted bobbin-retaining arms or latches 11<1> with upper bevels 13 and grooves 12 forming locking hooks. These latches carry pegs 16 working loosely in holes 21 and held normally in an horizontal position by springs 18. The bobbin carrier feet 11 are slotted at 10 as shown in Fig. 6 and pass round the discs 9 on notched driving-discs 5, the bevelled faces of which are arranged parallel to each other as shown. A bobbin-carrier is transferred from one disc 9 to another by the engagement of two arms 11<1> on adjacent cones 19. The arm 11' that is coupled to the bobbin-carrier is struck by an inoperative arm 11', which, owing to the mutual action of the chisel-shaped ends forces down the first mentioned arm, freeing the bobbin-carrier, the lower projection 7 of which is bevelled at 23. The bobbin-carrier is then taken by the arm 11', the previously-inoperative incline 13 on which passes over the bevel 23 and snaps into a groove. Certain latches may be switched out by providing them with pins 51 which are inserted in holes in the upper surfaces of the latches. The pins 51 of the latches so provided are pressed against the undersides of the corresponding discs 5 by the springs 18 thus displacing the latches to such an extent that they no longer co-operate with latches on adjacent cones 19.
