Patent GB-1077700-A (GB)
Title: Method of making a connection to aluminium wire and connector therefor
IPC: H01R4/62
Filed: 1966-01-17
Abstract: 1,077,700. End-terminals for wires. AMP Inc. Jan. 17, 1966 [Feb. 9, 1965], No. 2017/66. Heading H2E. To make a connection to an aluminium wire having a thin surface of oxidation-resistant conductive material, a sleeve 1 with a lining 6 of relatively soft conductive material such as silver on an alloy of tin or of cadmium and zinc, is crimped on to the wire so that the soft material is caused to flow. When the wire is multi-stranded, the soft material flows around the strands to form an air-tight seal. The sleeve 1 may have a contact tongue 5 and be surrounded by an intermediate metal sleeve 2 and an outer plastics sleeve 4 having enlarged portions 3 for crimping on to the cable insulation. The soft material may form an end cap or alternatively may be restricted to a portion lining an extension of the sleeve 1. The sleeve 1 may also have annular grooves formed in its inner surface, and in cases where the lining 6 is of readily fusible material, it is possible to subject the joint after crimping to a high current which fuses the material of the lining.

Title: Improvements relating to valves
IPC: F16K3/36
Filed: 1928-01-21
Abstract: 302,072. Leach, R. W., and Bateman, W. H. Jan. 21, 1928. Channels and reservoirs in valves.-In a valve comprising a cylindrical member a slidable axially within a body b, channels provided in the fixed and movable parts and supplied with lubricant under pressure are so arranged as to surround the aperture through the valve when the latter is open or closed, while the supply to those channels which are exposed during the movements of the valve is interrupted during such exposure. Lubricant is supplied from a chamber c in the body by a piston d subjected to spring or fluid pressure through a hole e into a short circumferential groove k in the body and a longitudinal groove f on the member a communicating by a passage i in the member a with diametrically opposite grooves k, f. The grooves f terminate at their lower end in a circumferential groove h on the member a and at their inner end communicate with a circumferential groove g in the body. Circumferential grooves j coplanar with the passage i are formed on the member a but do not completely surround the member, their ends communicating with the grooves k in the closed position of the valve and with the groove g in the open position. When the valve is either open or closed, all the passages are thus in communication with the chamber c and the aperture through the valve is completely surrornded by lubricant under pressure; but, during the opening or closing movements, the grooves j, which become exposed, pass out of communication with the supply.

Title: Apparatus for automatically regulating or measuring variations in ratio between fluid quantities co-operating with one another in operative processes
IPC: G05D11/13
Filed: 1960-01-20
Abstract: 945,476. Fluid-pressure servomotor control systems. P. GUARDIGLI. Jan. 20, 1960, No. 2070/60. Heading G3P. [Also in Division G1] The flows in two pipes A, B are maintained in constant ratio by apparatus including two U-tubes mounted on a rotatable shaft, the ends of respective tubes being subject to pressure-differences corresponding to the respective flows and acting on columns of liquid in the tubes, movement of the shaft owing to unbalance being arranged to actuate servo means for varying one of the flows in order to re-establish the altered ratio. The apparatus comprises a pair of upright vessels 1, 2 connected by a bottom tube 3 and fixed to a beam 4 mounted on the shaft 5 and a second pair of vessels 1<SP>1</SP>, 2<SP>1</SP> connected by a tube 3<SP>1</SP> and pivoted on a beam 4<SP>1</SP> carried by the shaft 5 so that their radius arms R can be adjusted, e.g. manually by a screwed toggle lint 11, 12, 13. The ends of the U-tubes thus constituted are connected by flexible pipes 9, 10, 9<SP>1</SP>, 10<SP>1</SP> to connection points 7, 8, 7<SP>1</SP>, 8<SP>1</SP> on a support rail 6, and corresponding pairs of these points are connected with flow restrictions in the pipes A, B so as to sense pressure differences which are transmitted in opposite senses as indicated to the corresponding liquid columns. An arm 14 on the shaft 5 causes, through an undefined servo-mechanism indicated diagrammatically at 0-0, actuation of a valve S in the pipe B, thereby restoring the flow ratio, if disturbed, to its preset value. The shaft 5 is loaded by a spring 15 counterbalancing a weighted arm.

Title: Electroformed Metallic Structures.
Inventor: BROOKS JOHN SPURGEON
IPC: E04C2/08
Filed: 1966-07-12
Abstract: 1,199,404. Electro-forming. FOAM METAL Ltd. July 11, 1967 [July 12, 1966; Jan. 14, 1967], Nos. 31145/66 and 2110/67. Heading C7B. A three -dimensional openwork material is formed by a series of tubes of electro-deposited metal running in random directions and joined together by electro-deposited metal, intercommunicating cellular spaces being formed between the tubes. Typically the material is produced by electro-deposition of metal on to the strands of a synthetic plastics open-cell foam material which has been rendered conductive. The plastics material may be a reticulated poly - urethane foam and may be rigidified by coating it with phenol-formaldehyde resin and made conductive by sprinkling conductive powder e.g. graphite or metal such as copper or copper bronze over the resin while it is still tacky. The foam material may be rendered conductive by chemical deposition of metal e.g. by reducing ammoniacal silver nitrate in situ with hydrazine hydrate or by sensitizing with stannous chloride, activating with palladium chloride and then effecting electroless deposition of silver, copper or nickel. Electro-deposition may be effected by pumping electrolyte, e.g. an acid solution of copper sulphate containing potash alum, through a tube 1 of insulating material in which a disc of foamed material 7 is located with a cathode connection being made to a silver face 10 of the disc and spaced from a grid anode 9. A subsequent electroplating of nickel may be applied. The plated plastic may be fired to remove the foam from the interior of the tubes leaving only a small ash residue.

Filed: 1944-02-04
Abstract: 570,064. Pliers. AIRCRAFT-MARINE PRODUCTS, Inc. Feb. 4, 1944, No. 2119. Convention date, Feb. 6, 1943. [Class 61 (ii)] [Also in Groups XXII and XXXVI] A ferrule is crimped or compressed on to the end of an electric conductor by means of dies that first compress the central part of the ferrule to flatten it to a lenticular cross-section and then grip the collapsed edges of the flattened area so that on completing the compression the metal of the ferrule flows inwards into close contact with the conductor, this flow eliminating any elastic tendency of the ferrule to open. The dies 31, 32 are of tapered section, Fig. 9, so that when the concave faces 33, 34 are formed thereon the centre part of the face is broader than its extremities where it merges into the flat portions 35, 36. The curvature of the surfaces 33, 34 causes the dies to grip first at the centre where the joint of a rolled ferrule will lie, and after partial compression the flattened edges are gripped by the portions 35, 36. The dies may be formed on the jaws of a pair of pliers that may also have a cutting edge and a formation for stripping the conductor. The ferrule may be formed of annealed copper that becomes work-hardened by the compression, or of soft copper, in which case it has an outer seamless sleeve of harder copper. The interior of the ferrule may be annularly ribbed. Specification 569,366, [Group XXXVI], is referred to.

Title: Improvements in or relating to safety devices for electrically driven vehicles
IPC: B60L3/02
Filed: 1948-01-23
Abstract: 633,534. Fluid-pressure brakes. GENERAL ELECTRIC CO., Ltd., and TURRALL, J. C. Jan. 23, 1948, No. 2143. [Class 103 (i)] In the braking system of an electrically-driven vehicle, the brakes are applied by the closing of valves 23 or 38 controlling the pressure in a vacuum pipe 37 or compressed air pipe 39, these valves 23 and 38 being normally held open by the energization of coils 22 or 40 respectively connected in a circuit between supply lines 10 and 11. When the vehicle is stopped, current is supplied through the normally-closed contacts of a cut-out relay 21 and the relay switch 18. The switch 18 is closed by the operation against the action of spring 14 of a fluidpressure actuated relay device 2 with compressed air supplied through one-way valve 31 and an electrically-operated valve 1 from a pipe 4 to a pressure source. Valve 1 is initially opened to supply compressed air by closing one or the other of two "dead man's handles" 6 or 25, located in the driver's cab at each end of the vehicle, so as to energize its coil 3. When the vehicle is started by operation of either of the master controllers 8 or 27, as soon as the handle is moved from its " off " position, the segment 34 no longer bridges the contacts 7 or 26 so that the coil 3 of valve 1 is energized only by current flowing from line 10 to line 11 through one or the other of relay switches 17, or 19, the circuit through switch 18 and the contacts 29 and 30 being broken by the movement away of segments 35 or 36 as soon as one or the other of the reversing controllers, also shown at 8 and 27, is moved to an operating position. In the event of the driver now releasing his " deadman handle" 6 or 25, coil 3 will be de-energized and valve 1 operated to shut off the air supply from pipe 4 to exhaust to atmosphere the air operating the relay 2 so that the switch 18 is opened and valves 23 or 38 closed to apply the brakes. Due, however, to the combination of a reservoir 33, an adjustable outflow device 32, and the one-way valve 31, the air pressure in the relay 2 will not be reduced instantaneously, and there will be a delay period between the release of the " deadman handle" and the opening of switch 18, this delay period being adjustable by device 32.

Title: Improvements in or relating to antispasmodic agents and their preparation
Filed: 1950-01-27
Abstract: The invention comprises compounds of the formula R1R2C(OH)-CHR5-CH2-NR3R4, and their non-toxic salts, where R1 is aryl or cycloalkyl, R2 is alkyl, R3 and R4 are alkyl which may form a ring with the N atom and R5 is C1-C4 alkyl. These are made by reacting ketones R1-CO-CHR5-CH2-NR3R4 with organometallic compounds R2M, where M is an alkali metal or MgHal, and hydrolysing the product. Treatment with a strong acid whose anion is known to be non-toxic gives the corresponding salt, e.g. hydrochloride, hydrobromide, hydriodide, sulphate, citrate, tartrate, lactate, sulphamate or ethanesulphonate.  Quaternary salts may be made similarly, e.g. methochloride, ethobromide, methiodide, propyl iodide, benzyl chloride, methyl methosulphate and methyl p-toluenesulphonate.  The organometallic reactant may be a Grignard reagent or an alkyl-sodium, lithium or potassium; this is used in excess, especially when a ketone hydrochloride is employed.  Examples show the production of 4-diethylamino-3-methyl-2-phenyl - 2 - butanol, 4 - dimethylamino - 3-methyl - 2 - phenyl - 2 - butanol, 1 - dimethylamino - 2 - methyl - 3 - phenyl - 3 - hexanol and 1 - dimethylamino - 2 - methyl - 3 - phenyl 3 - pentanol and their hydrochlorides. R1 may also be cyclohexyl, cyclopentyl, naphthyl, xenyl or a halo-, alkyl-, or alkoxy-substituted aryl radical such as chlorophenyl or anisyl. Specification 307,304, [Class 2 (iii)], is referred to.  Aminoketones of the above formula are made by (1) the Mannich reaction, e.g. b -diethylamino-isopropyl cyclohexyl ketone from ethyl cyclohexyl ketone, formaldehyde and diethylamine hydrochloride; (2) Friedel-Crafts reaction of b -(tert. amino)-acyl halides with aromatic compounds; (e) addition of amines to a  : b -unsaturated ketones.

Abstract: 744,612. Time switches; switches held set and freed mechanically. HORSTMANN GEAR CO., Ltd. Jan. 26, 1954 (Jan. 26, 1953], No. 2210/53. Class 38(5) [Also in Group XXIX] In timing devices in which operation of the device (e.g., a switch) is caused by tappets, two of which, 4, 11 are manually adjusted relatively to a rotatable 24-hour dial and two of which, 2, 3. are automatically adjusted relatively to the dial throughout the year (e.g. by the means described in Specification 395,813), a tappet 2 of the latter type is arranged to move a tappet 4 of the former type into an inoperative position, when. at a certain time of the year, tappets 2 and 4 have approached to within a certain distance of each other. The automatically adjustable (solar) tappets 2 and 3 are arranged respectively to open and close the switch and the manually adjustable (manual) tappets 4 and 11 are arranged respectively to close and open the switch. Tappet 4 is driven by a pin 7 inserted in a selected hole 17 in the dial 8. Tappet 11 is formed by the leading edge of a segment 12 of adjustable circumferential length and when it engages a pin 36 on the "off" arm 26 of the switch, the arm is tilted anticlockwise about a pivot 28 into the dotted position shown in Fig. 11 where it is retained so long as the segment 12 is pass. ing beneath it. This movement of arm 26 removes a catch 29 thereon from over a lug 25 on a lever 23 pivoted at 24, this lever thereupon being tilted clockwise by the engagement of a contact carrying spring 19 with a roller 21 on the lever 23 so that the contacts open. At the same time a pin 31 on arm 26 moves a link 32 anti-clockwise about its pivotal connection 33 with a bell-crank lever 34 carrying the "on" arm 35. If now the tappet 2, by means of a screw 40 thereon which can engage a pin 41 on tappet 4, moves the tappet 4 clockwise in advance of the pin 7 so that tappet 4 overlies the trailing end of segment 12, the tappet 4, even though it engages and tilts anti-clockwise the "on" arm 35 of the switch, cannot cause the switch to close, because the return movement of lever 34 by a spring 45 cannot bring a lug 32a on link 32 (which is still held by pin 31) over the lug 25 to tilt the lever 23 and reclose the contacts. The dial may be driven by clockwork or an electric motor.

Valves closing after predetermined flow. - A flushing-valve is opened by a push acting against a spring, and is retained open by a catch released by a turbine, fan, or screw rotated by the flow of fluid and connected to the catch by worm gearing. The main valve 19 is slidably mounted on a spindle 20 fitted with a pilot valve 42 for giving an after-flush. The turbine blades 24 are secured to a plate 25 having a tubular extension 26 passing through a dividing-wall 12 and around the spindle 20. The member 26 carries a worm 27 adapted to actuate a worm-wheel 28 on a shaft 29 provided with a second worm, which drives a wormwheel on a vertical shaft provided with a toothed wheel meshing with the pinion 34 rotatably mounted on the extension 26. The pinion 34 is shaped internally to receive a member 35 secured to the valve spindle and provided with a tooth 36 normally housed in a recess 39. When the push is depressed, the member 35 passes into the pinion 34, which is rotated by the turbine to pass the projection 36 under the cap 17 which holds the valve in the open position and until the pinion 34 and valve spindle have made one complete revolution. The under part of the cap 17 near the recess 39 may be inclined to allow the valve to close gradually. Instead of the radial-flow turbine shown, an axial-flow turbine or a Pelton wheel may be used.

Filed: 1960-01-21
Abstract: 880,353. Feedwater supply systems for steam boilers. CROOK, C. Jan. 21, 1960, No. 2320/60. Class 123(2) A steam boiler 2 is fired by an automatic stoker 4 driven by a motor 6 having a starter 8 and is fed with water by a pump 16 driven by a motor 20 having a starter 22. The boiler is fed with fuel only during a proportion of a fixed cyclic time interval, for example, for 30 seconds in every minute, the time of feed in each interval being adjusted according to variations in boiler conditions such as steam pressure. The starters 8, 22 are connected in a circuit including contacts 36 which are closed when the water in the boiler drops to a predetermined low level and are opened when it rises to a predetermined high level, the arrangement being such that the starter 22 operates to start and run the pump 16 only when the stoker motor is running and the contacts 36 are closed, that is, when the water level in the boiler is below the "high" level. The pump continues to feed water until the high level is reached or the stoker motor stops at the end of its feed interval. A switch 42 is provided to short circuit the starter 8 and start the pump if the level in the boiler becomes dangerously low. In a modification the pump 16 runs continuously and the feed supply to the boiler is controlled by an electrically operated valve in a pump return by-pass line or in the suction or discharge line from the pump, the valve being controlled by the starter 8 and the float switch as for the starter 22.

Abstract: 547,492. Inductances. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Feb. 28, 1941, No. 2716. Convention date, Feb. 29, 1940. [Class 38 (ii)] Relates to inductances for simultaneously tuning two or more oscillatory circuits such as the signal input and local oscillator circuits in a superheterodyne radio receiver by simultaneous movement of magnetic cores 9, 13, and consists in providing for initial adjustment of the inductances to facilitate " tracking ". At least one of the inductances is wound on a former 7 over a strip 8 which is subsequently withdrawn so as to leave a part of each turn 6 unsupported. Thus any turn or group of turns such as those 10, Fig. 3, may be pressed inwards nearer to the core to determine the amount of inductance variation with core movement. To permit further adjustment of this kind, the core 9 may be made non- cylindrical or may be eccentrically mounted on its operating rod 19 so that by rotating the latter the core may be adjusted with respect to the winding. Subsequent tuning is effected by a screw 21 operating to move both cores simultaneously.
