Title: Improvements in and connected with electric switch resistances
IPC: H01C10/02
Filed: 1931-09-10
Abstract: 381,689. Conducting-liquid switches. RUPPEL, S., 8, Palmengartenstrasse, Frankfort-on-Main, Germany. Sept. 10, 1931, No. 25450. Convention date, Sept. 10, 1930. [Class 38 (v).] Thermal switches ; sparking- preventing devices ; contacts.- A circuit is broken between electrodes 2, 3 on the passage of sufficient current through the resistance liquid 12, which may be water with or without addition of NaCl or soda lye, between them, the liquid being heated to evaporation and the vapour acting on the liquid to depress it and drive it from between the electrodes 2, 3 into the space 12. Complete interruption of the circuit occurs when the liquid level drops below the electrode 3 and on condensation of the vapour, the apparatus restores, aided by a spring 11 between the lid 10 and an extension of the electrode 3. In the process of switching off the resistance is continuously increased until final interruption takes place, which latter may be effected by a piston-like conducting member within the electrode 3 being expelled from the electrode. A further modification consists in interposing an insulating cylinder between the electrodes and in fitting a piston to the electrode 3 whereby it is moved to vary the resistance. Apertures in the insulating cylinder may direct a stream of vapour across the final rupturing point to choke the arc. The electrodes may be shortcircuited normally by a heat-sensitive thermal strip which deflects at a certain current value and inserts the resistance liquid. In another form a closed capsule is formed by a pair of spaced, inwardly-bowed diaphragms (which may be of bimetal) enclosing liquid between them and carrying contacts at their centres normally in engagement. The vapour causes the diaphragms to be bowed outwardly, separating the contacts and increasing the resistance until final interruption. An insulating plate divides the capsule and has a nozzle-shaped opening to allow the contacts to engage, the opening allowing a stream of liquid to quench any arc that may be formed. The electrodes may be of chrome-nickel, pure iron (for instance electrolytically deposited) or other resistance material and may be actuated indirectly by the vapour, and may also be specially shaped to modify the characteristics of the device.

Title: An area road traffic control system
IPC: G08G1/08
Filed: 1969-05-19
Abstract: 1,274,244. Road signals for controlling traffic. OMRON TATEISI ELECTRONICS CO. 19 May, 1969 [30 May, 1968], No. 25463/69. Heading G4Q. A traffic control system for a road netwrok consisting of six intersecting main highways 11 ... 16 and eight local roads 21 ... 28 comprises dividing the network into a number of unit zones each centred about the intersection of two main highways. These intersections are designated I 1 ...I 9  and are provided respectively with zone control devices 31...39. Each device 31...39 controls traffic signals (not shown) within its corresponding zone. Vehicle detectors 41, 41<SP>1</SP> ... 52, 52<SP>1</SP> are situated between adjacent pairs of the intersections I 1 ...I 9 . The dash lines in Fig. 1 show the extent of the unit zone centred on intersection I 5  and Fig. 2 shows in block diagram form the circuit connections for that zone, the other unit zones being similar. As shown, the vehicle detectors 44, 44<SP>1</SP>, 46, 46<SP>1</SP>, 47, 47<SP>1</SP>, 49, 49<SP>1</SP> on the periphery of the unit zone supply signals to the zone control device 35 and to a central control station 61. The zone control devices of the other unit zones similarly receive signals from the corresponding vehicle detectors and the station 61 receives signals from all the vehicle detectors. Consequent upon the traffic retardation as computed by the station 61 the traffic is controlled in one of three ways as shown in Fig. 3. The station 61 determines whether signals from any one of the four pairs of detectors of any zone are above a certain level and indicate a heavy traffic volume. Such zones having a heavy volume are controlled as a group directly by the station 61 to an optimum predetermined traffic control pattern. If the traffic volume is below this level the zone is controlled by its control device and the station 61 disconnects itself from that zone. However, if the traffic volume is relatively heavy but there is a large variation of traffic volume with respect to time, the zone is disconnected from the station 61 and is controlled by its control device which additionally applies retardation control.

Title: Improvements in intermittent driving mechanism
IPC: D01G19/20
Filed: 1920-09-06
Abstract: 172,408. Nasmith, J. W. Sept. 6, 1920. Combing-machines.-An arrangement of intermittent toothed gearing for driving the detaching rollers of Heilmann and Nasmith combing-machines, but also applicable to other purposes, comprises a cam-driven oscillatory sector 6 in constant mesh with an intermediate pinion 10 adapted on each reversal of the motion of the sector to be moved into or out of engagement with a driven pinion 16 rotatable in fixed bearings. The pinion 10 may be carried in a slidable bearing or, as shown in Fig. 1, by a lever 8 pivoted at 7 concentrically with the sector 6, the bearing or the outer end of the lever 8 carrying. an adjustable arm 11 with a roller 12 engaging a cam 13 rotating synchronously with the main driving cam 1 so as to move the pinion 10 into and out of engagement with the pinion 16 at the required times, the lift of the cam 13 being arranged so that the pinion 10 moves without rotating on its axis during such displacement. The cams 1, 13 are face cams, only the inner edges of the cam grooves being shown, and serveto impart a progressive to-and-fro motion to the pinion 16 with intermediate pauses as required for the detaching rollers of combing-machines. By eliminating the rise 18-19 on the cam 1, a simple intermittent forward motion is imparted to the gear 16.

Title: Improvements in or relating to the compression-moulding of thermoplastic compositions
IPC: B29B13/02
Filed: 1944-12-21
Abstract: A thermoplastic composition containing a predominating proportion of thermoplastic material is heated by means of a high-frequency electrostatic field and transferred to a mould. Direct moulding pressure is then applied thereto and the moulded article is cooled or allowed to cool below the softening point while still in the mould and then removed from the mould.  The heating is effected at a power input which heats the material to moulding temperature substantially uniformly throughout its mass within a time which is sufficient to bring about substantial breakdown or discoloration of the material. The mould may be kept cool.  Fillers may be selected to aid the high frequency heating. Specifications 517,798 and 572,425 are referred to.  The Specification as open to inspection under Sect. 91 comprises drawings showing simple moulds for use in the invention.  There drawings do not form part of the Specification as accepted.

Title: Electrical conductors
IPC: H01R11/11
Filed: 1972-06-01
Abstract: 1372285 Making terminals ESSEX INTERNATIONAL Inc 1 June 1972 [1 June 1971] 25724/72 Heading B3A [Also in Divisions H2] A method of forming a terminal 18, Fig. 8, integrally at one end of a metallic electrical conductor 10, Fig. 3, comprises subjecting the conductor to axially compressive force sufficient to heat the metal at that end and cause it to flow. The metal necessarily flows both axially and radially of the conductor end. The conductor 10 is placed between die parts 2, 3 of a die assembly (1), Fig. 1 (not shown), which are then clamped together. Groove 5 may be undersized or roughened to aid clamping of the conductor. A forming tool 15 with a head 16 of required configuration and cross-sectional area is introduced into chamber (c). The free end of the wire is then subjected to the axially compressive force so that it resumes a shape and cross-sectional area corresponding to the chamber. The head 16 may be moved axially so as to form the terminal by swaging, or it may be moved axially and rotated, either simultaneously with or after application of the force, so as to form the terminal by a swaging and spinning process, thus giving the terminal a smoother surface (21), Fig. 4 (not shown). The conductor may be formed of stranded wire, or a single wire filament (24), Figs. 5, 6 (not shown). The end surfaces (30), (30a) of the terminal may be concave or flat and metallic powder, e.g. silver, having better electrical conductivity than the conductor material may be distributed over the terminal end surface during the swaging process. The finished terminal may also be dipped in molten tin. An insulating sleeve (31), Fig. 7 (not shown), comprising a glass-filled resin, may be formed around the neck (19), adjacent portion of the insulation 12, and terminal 18. Multiple conductor connectors may be formed by adapting the above described terminals by enclosing conductors 38, Fig. 8, in a body member 36 corresponding in number to conductors in body member 35. The terminals 18, 39 of the conductors may bear directly against each other, or alternatively, an elastomeric member 40 may be introduced therebetween. The member 40 comprises a pad 41 of resilient, compressible, non-conductive material, e.g. hard silicone rubber, with inserts 42 of such non-conductive material with conductive particles 43 dispersed therein. Therefore, upon compression of the pad 41 by the members 35, 36 a conductive path is established through the inserts 42 between each pair of terminals 18, 39.

Filed: 1956-08-23
Abstract: 864,457. Electrolysers; fuel cells. E.R.A. PATENTS Ltd. Sept. 19, 1957 [Aug. 23, 1956], No. 25802/56. Classes 41 and 53. An electrolyser for water, which can be operated in reverse as a gas battery or fuel cell has porous nickel electrodes in which the pores in the faces in contact with the electrolyte are smaller than the pores on the opposite faces so that the generated gases force the electrolyte out of the pores but are prevented from bubbling into the electrolyte. The electrode at which oxygen is evolved is provided with a porous non-conducting coating on the face in contact with the electrolyte whereby the oxygen is prevented from being liberated directly into the electrolyte. The apparatus shown is similar to that described in Specification 864,456 and comprises a stack of bipolar electrodes 1, each of which consists of a central nickel plate having a recess on each side containing porous nickel which is spaced a short distance from the plate. The spaces between the electrodes are filled with a solution of potassium hydroxide. The outer faces of the oxygen electrodes are coated with porous non-conducting green nickel oxide, or magnesium oxide, and the inner faces are prevented from corrosion by a layer of black nickel oxide containing lithium, as described in Specification 864,456. Current is supplied to the electrodes 1 and hydrogen and oxygen are evolved from the rear faces of the nickel fillings and are led away through passages 51, 52. Specifications 667,298 and 725,661 also are referred to.

Title: Stepping motor drive
IPC: G05B19/27
Filed: 1964-06-24
Abstract: 1,024,515. Selective signalling. GERBER SCIENTIFIC INSTRUMENT CO. June 24, 1964 [July 10, 1963; June 12, 1964], No. 26090/64. Heading G4H. [Also in Division H2] In a step-by-step motor control system primary pulses, 144, Fig. 3, are fed sequentially, as secondary pulses, to a plurality of step-bystep motors 112a, 112b etc., arranged to drive a single shaft 140. The result is that shaft 140 experiences a larger, and more smoothly applied, torque than that possible with a single step-by-step motor, because the resulting rate of impulsing of the shaft 140 can be several (four as shown) times the input frequency limit for each step-by-step motor. Other ways of coupling rotors of step-by-step rotors are to have several rotors on one shaft, Fig. 7, or to have a single rectangular rotor, Fig. 10, associated with several sets of stator poles. To obtain more uniform impulsing of the final drive shaft the several rotors can be slightly staggered, Fig. 11, whereby each time a set of stator poles is energized the associated rotor is in line with them.

Title: Control apparatus for a water supply system

Filed: 1974-06-12
Abstract: 1405242 Fluid pressure servo motor systems WEIL-MCLAIN CO Inc 12 June 1974 [19 Nov 1973] 26110/74 Heading G3P A control apparatus for a water system in which water is pumped through a line 12 by an electric motor-driven pump 10, to one or more valved outlets 14a, 14b, and the starting and stopping of the pump motor 11 is controlled so as to maintain the water pressure within a narrow pressure range, as the flow varies between a low by-pass rate and a full pump delivery rate, the apparatus comprises a valve 21 having a closure member 41 attached to a diaphragm 42, and a flexible seat 36, the member 41 comprising an unrestricted flow portion 41b, a first flow-regulating portion 41e, and a further flow-regulating portion 41d, a pump motor control switch 20 responsive to the discharge pressure from valve 21, being provided. Portion 41c has a by-pass notch 41c, and air is supplied above the diaphragm at 56. In operation, with the closure 41 in the Fig.2 position, one of the valves 14a, 14b, is opened so that switch 20 is actuated to start pump 10. The pressure is rapidly built up and the diaphragm moves upwardly until portion 41c of the closure, throttles the flow and thus maintains the delivering pressure below the upper switch operating pressure, and the water flow through the notch is at the minimum draw rate. If the rate at which water is removed is less than this rate, the pressure builds up and switch 20 switches off the pump motor. Due to the inclusion in the circuit of an air chamber 61, and a pneumatic water accumulator 62 the pump tends to run-on after water-flow has stopped. In order to reduce this run-on time, closure 41 is adapted to pass through the seat until portion 41d allows a rapid filling and pressurizing of the system up to the upper switch operating pressure. If the pump discharge line 12 is of a non rigid type the discharge pressure acting on this pipe will cause it to expand when the pump is operating, and when the pump is stopped and the check valve 12a is closed the pipe will contract so as to increase the delivering pressure. In order to prevent this happening valve closure 41 has a portion 41e which is adapted to shut-off the flow.
