Abstract: 941,382. Electromagnetic relays. ENGLISH ELECTRIC CO. Ltd. Dec. 16, 1959 [Dec. 23, 1958], No. 41496/58. Heading H2B. A time-overcurrent relay has an operating winding 10a formed as a printed circuit on a disc rotor 10 arranged to pass between the poles of a magnet 12 in such a manner that the torque is independent of the rotor position or related to the spring return force on the rotor. The current flows in the same direction in all paths P, Q, R which pass between the poles and the paths may increase in radial length as the rotor moves from the rest position to the position shown. The insulating disc 10 may be backed with copper to give eddy-current breaking. In Fig. 3, the electromagnet 12 is in series with the winding 10a and a breaking magnet 18 acts on a conductive coating 10b which is outside the influence of the magnet 12.

Title: Electrical signalling systems and automatic telephone exchanges
IPC: H04Q11/04
Filed: 1962-11-02
Abstract: 981,174. Automatic exchange systems; multiplex pulse code signalling. STANDARD TELEPHONES & CABLES Ltd. Nov. 2, 1962 [Nov. 8, 1961], No. 41611/62. Headings H4K and H4L. In a pulse-code-modulation, time-divisionmultiplex exchange system in which channels of a primary highway are connected to channels of a secondary highway via a co-ordinate switch, the time slot allocated to the transfer of a single pulse from a first data store associated with one highway to a second data store associated with the other highway is subdivided into at least three, so-called, basic time slots whereby during a first basic time slot a pulse is passed from the first data store to a bi-stable circuit, during the second basic time slot it is transferred via the switch to a second bi-stable circuit and during the third basic time slot it is passed to the second data store. The system is generally similar to those described in Specifications 972,337 and 981,175 but the control circuits (Fig. 3, not shown) include additional elements which allow more precise control of the read-out and write-in times for the data stores (111, 112, 141, 142). It is stated that the use of the bi-stable circuits prevents undue distortion of the pulses caused by the response times of the semi-conductor elements used in the system, parasitic capacitances in the stores and switch and the different lengths of conductor between the various highway terminating circuits and the switch. Each highway consists of an incoming and outgoing line connected respectively to an incoming and outgoing data store e.g. 111, 112, the stores comprising for example 24 rows of ferrite cores each row of which is associated with a particular channel on the corresponding highway. Information is transmitted in the form of a seven digit binary code, there being an additional 8th digit for signalling and synchronizing purposes. A connection time slot tz (4 Ásecs.) is allocated for the bidirectional transfer of information between highway circuits 110 and 140, this time slot being unrelated to either of the slots in use for a particular call on the highways. The connection time slot is divided into p digit time slots wherein p is equal to the number of digits in the binary code viz. 8 in this case, and each of these digit time slots is divided into four basic time slots a, b, c, d (125 nsecs.). During a digit time slot p, bistable circuit 145 in highway circuit 140 is reset to zero at basic time a whereby any information in store 141 may be transferred thereto at basic time b. The signal is then passed via gate 103, crosspoint R2C3 and gate 104 to a second bi-stable circuit 116 during basic times c, d and is eventually written in store 112 at basic time b of the succeeding digit time slot p + 1. Similarly incoming store 111 of highway circuit 110 is read at time d of digit time slot p and the information so obtained is eventually written into outgoing store 142 at basic time d of the succeeding digit time slot p + 1.

Abstract: 963,124. Valves. CYCLES PEUGEOT. Nov. 9, 1962 [Nov. 13, 1961], No. 42371/62. Heading F1B. A rotary valve 5, Fig. 4 for a two stroke engine is circular in shape and has a peripheral valve port 8 behind which a resilient strip 7 is maintained by its ends and is, in the state of rest, spaced away from the valve port, the strip moving outwardly under the effect of centrifugal force to progressively close the valve port and thus limit engine speed. The strip e.g. of steel, rests in a cavity 10 of the crank-shaft counterweight and the port is formed in a rim 6, fixed to or formed integrally with the counter weight. Gas is inducted through passage 2, and passes through port 8 and the lateral openings of the cavity 10 in the counterweight and also when port 8 clears edge h, through groove 4. The valve may be formed as an auxiliary device which is attached to one of the counterweights. In further embodiments the valve may control the gas transfer passages or both the crankcase inlet and the transfer passage and pairs of rotary valves may be disposed in parallel, one on each side of the piston rod.

Abstract: 1,202,438. Fluid actuation of switches. INDUSTRIONICS CONTROLS Inc. 18 Sept., 1967 [18 Oct., 1966], No. 42376/67. Heading H1N. [Also in Division H2] Control apparatus includes an electric switch 58, 61, 62, a switch actuator including a pressure chamber 74 having a movable wall 24, flowthrough passages including inlet and outlet passages 96, 84 lower port through which a fluid flows, an aspirator having a suction chamber 86 and a fluid passage 92, the aspirator drawing a partial vacuum when there is flow of fluid through fluid passage 92, and a pressure exchanging passage, 84 upper port, through which pressure chamber 74 communicates with suction chamber 86 to change the pressure in pressure chamber 74 in accordance with the rate of flow of fluid through the flow-through passages. Air (or other fluid) passes from a supply line (not shown) screwed into opening 96, through tube 92 and orifice 95 into passage 84 lower port and out of its lower end. There is a small space between the outside of tube 92 and the inside of passage 84 lower port and the downwardly directed air stream from orifice 95 aspirates air from chamber 86 and causes a reduction of pressure in passage 84 upper port and in the spaces under diaphragm 24. Whenever the outlet from the lower end of passage 84 is partially, or totally, obstructed, the aspirating action is reduced or terminated and there is an increase in pressure in chamber 86 and the spaces under diaphragm 24. With sufficient increase in pressure, diaphragm 24 moves upward and contact 58 bridges fixed contacts 61, 62 connected by leads 64, 64<SP>1</SP> with terminals 66, 661 in socket 44. Permanent magnet 76 and disc 70 attached to the underside of diaphragm 24 provide snap action. Contacts 58, 61, 62 may be of tungsten carbide and the latter two may have concave contact faces. To increase the wiping action, as contact 58 moves upwards it may touch one of contacts 61, 62 first, then be deflected by this to touch the other. The obstruction for the outlet from the lower end of passage 84 may be provided by a lobe 120 on a cam 116 which rotates on shaft 118. Alternatively it may be provided by the passage of a workpiece. The end of passage 84 may be located differently and may be connected to an extension such as a flexible tube. A pushbutton may be substituted for the cam or workpiece.

In a track diagram, Fig. 1, in which the establishment of a route through an associated track layout is indicated by the illumination of a series of apertures positioned along the selected route, a lamp, which illuminates aperture 20 when the associated points are correctly set to normal for route 10(1) and to reverse for route 10(2), is also used for indicating a fault condition in the points circuitry or operating mechanism. The lamp X, Fig. 4, illuminating aperture 20, is energized e.g. for route 10(1) from a steady power source S via contacts of route setting relay 10(1)LR in reverse, points indicating relay 20KR at normal and relay 20.OCR, which indicates correspondence between points setting relay 20WLR (not shown) and points indicating relay 20KR, in its energized condition. Should the points fail to move to normal, relay 20.OCR releases after a predetermined release period and lamp X is energized from intermittent power supply F, indicating by its flashing a fault in the points operating mechanism. Should the points setting relay fail to respond when route setting relay 10(1)LR is switched to its reverse position, both supplies to the lamp are cut off and the unilluminated lamp indicates a fault in the setting relay circuitry.
