Title: Zero-insertion-force edge connector
IPC: H01R12/89
Filed: 1975-07-11
Abstract: 1513183 Two-part couplings SOCAPEX 11 July 1975 [12 July 1974] 29347/75 Heading H2E A zero insertion force connector for printed circuit boards etc. comprises one part having elastic strip contacts 22 mounted in an insulating body 23 which comprises a longitudinal shaft 27 having lateral relief portions 19, and at least one thruster element 24 which is itself displaced, by the portions 19 when shaft 27 is rotated, so as to push contacts 22 against the contacts 21 of a circuit board 20 which has previously been plugged in by sliding the groove 30 along projection 31 in the direction of arrow 32. A sector 34 on shaft 27 may be provided to abut the edge 35 of the board and lock it in position when electrical contact is made. In an alternative embodiment (Fig. 3, not shown) contact is made with two sides of a circuit board by having two rows of elastic strip contacts and two thruster elements separated by the longitudinal shaft. The thruster elements have integral or detachable beads (44, 45) which may be so positioned as to make contact between different pairs of contacts according to the degree of rotation of the shaft. The circuit board is mounted in a slide 40, shown in Fig. 5. In the embodiment of Fig. 5 the longitudinal shaft undergoes translation along its axis rather than rotation hence the relief portions 71, 72 are cone shaped. Alternatively, the thruster elements may each operate on only two contacts (Figs. 4 and 6, not shown) so that by correct positioning of the relief portions, selective electrical contact may be made. Fig. 7 (not shown) shows a shaft which undergoes both rotation and translation.

Title: Improvements in or relating to extrusion dies
IPC: B21C25/02
Filed: 1948-11-11
Abstract: 672,129. Extruding; composite casting. FIELDING & PLATT, Ltd., ROWLES, R. V., and GENDERS, R. Nov. 9, 1949 [Nov. 11, 1948], No. 29356/48. Classes 83 (i), 83 (ii) and 83 (iv). [Also in Group V] An extruding die is composed in part of a metal or alloy having a higher thermal conductivity than the working surface of the die so that heat may be more readily conducted to or away from the working surface. The main mass 1 of the die may be of chromium-copper alloy to which a thin annular plate 2 of tungsten-chromium or similar steel is applied to form the working surface or a cast plate having a boss extending part of the way along the die orifice may be employed. Alternatively, the surface 2 may be deposited by electrodeposition, welding or other means. In a modification, the main mass 4, Fig. 3, of the die may be of hard steel to which inserts 5 or casings enclosing part of the die, are fitted. The more conductive masses assist in the flow of heat away from the working surface and prevent plastic flow of that surface but heat may be applied through any desired portion of the die to the material being extruded or a proportion of the die surface may be protected by a layer of low-conductivity material in order to restrict the area of the die from which heat is extracted. Composite casting.-The plate having a boss may be cast in the form required and the main mass 1 cast in contact with it, the " lostwax" casting method being employed. Billet containers.-The Provisional Specification also refers to the application of the invention to the billet container of an extruding apparatus.

Abstract: 1396075 Bowling alleys PATENTVERWERTUNGS - UND FINANZIERUNGSGESELLSCHAFT SERANIA AG 22 June 1973 [28 June 1972] 29745/73 Heading A6D In a bowling pin setting apparatus of the type in which each pin 1 is connected to a rope 2, each rope 2 passes around a pulley 5 and the pulleys 5 are mounted on arms 30 on a common bar 12 each end of which is connected to an endless chain which is driven at. a constant speed, the bar 12 carrying a lever 28 which engages a cam ramp 32 to reduce the speed of descent of the pins just prior to the pins being set on the floor 23. As described each rope 2 passes through a centering device, around a fixed pulley 3, around pulley 5 and the end is secured to a spring loaded drum 6. Each drum 6 is mounted on an arm 9 which can pivot about pin 7 against the resistance of spring 8. Each endless chain 13 passes around two wheels 14, 15 and the chains 13 are driven at a constant speed by motor 17 via belt drive 18 and gearing (not shown). The apparatus operates as follows:-initially the bar 12 is located adjacent the wheels 14 and to reset the pins the motor 17 is started. The bar 12 moves in the direction of arrow E to raise the pins 1 which enter the centering devices 35 as the bar 12 passes the wheels 15. When the pins enter the centering devices 35 the movement of the bar 12 causes the arms 9 to pivot about pins 7 against the pressure of spring 8. The bar 12 then moves in the direction of arrow A to lower the pins. Just before the pins reach the floor 33 a roller 29 on the arm 28 engages a cam ramp 32 which causes the bar 12 to pivot in the direction of arrow C to reduce the speed of descent of the pins to one third of their former speed. After the pins have been set on the floor the arm 28 clears the ramp 32 and when the bar 12 reaches the wheels 14 the motor 17 is stopped. If the ropes become tangled when the pins are being raised the arms 9 pivot about the pins 7 to open a switch to stop the motor 17 and the pins descend under gravity When the ropes become untangled the motor 17 starts again. A second switch in parallel to the first switch is closed when the pins enter the centering devices 35. so that the motor 17 does not stop when the arms 9 pivot as the bar 12 passes wheels 15.

Title: Method and apparatus for producing carbonic acid gas
IPC: C01B32/50
Filed: 1926-11-25
Abstract: 278,304. Lundin, B. Sept. 28, 1926, [Convention date]. Carbon dioxide; sodium sulphate. - In generating carbon dioxide by feeding solid sodium or other alkali-metal bicarbonate into an aqueous solution of sodium or other alkalimetal bisulphate, the gasoutlet pipe is fitted with a device such as a pump or compressor to regulate the pressure at which the gas is discharged. A generating chamber 3 to which bisulphate solution is supplied, is surmounted by a chamber 5 for holding the bicarbonate, and contains a rotary shaft 7 carrying agitators 11, 15, and scrapers 14, which serve to force the bicarbonate through openings 13 into the chamber 3. The gas passes out through a water washer and through the pump or compressor to a reservoir. When the pressure falls the pump is operated to produce a reduced pressure in the chamber 3 and withdraw dissolved carbon dioxide. To remove air from the apparatus, a current of steam may be passed through it, or the chamber 3 may be filled with bisulphite solution, which is afterwards expelled to the desired level by admitting carbon dioxide. The chamber 3 may be lined with lead or formed of rustless iron. The strength of the solution used in the chamber 3 is arranged so that a solution of sodium sulphate saturated at about 33‹ C. is obtained after generation of the gas, and the bulk of the sodium sulphate is separated as crystals on cooling.

Title: Improved device for controlling the engagement of automatic clutches, particularly for motor vehicles
IPC: B60K23/02
Filed: 1958-09-18
Abstract: 850,448. Gearing for stopping and starting machinery. FICHTEL & SACHS A.G. Sept. 18, 1958 [Nov. 9, 1957], No. 29961/58. Class 80 (2). The re-engagement of the main clutch of a motor car following a ratio shift is speeded up by an inertial mass responding only to acceleration of the car to actuate the clutch controlling mechanism. The disengagement of the clutch may be effected by oil pressure, compressed air or vacuum servomotor means. In one form, movement of the car gear shift lever energizes a solenoid 2, Fig. 1, which acts upon an armature 3 to open a valve 4 against the bias of its spring 5, thereby connecting a passage 7, leading to the engine inlet. manifold, through a port 8 to a servomotor (not shown) disengaging the main clutch. When the newly selected ratio has been established and the ratio shift lever released, the solenoid 2 is de-eneigized and the spring 5 closes the valve 4, at the same time connecting the port 8 leading to the vacuum servomotor to a bleed hole 17 through which air seeps for gentle re-engagement of the clutch. If the throttle of the motor car is opened to produce rapid acceleration, a mass 13 pivots and, through a strut 16, opens a valve 10 so that air is admitted through the valve 4 and the port 8 to the servomotor for rapid clutch re-engagement. The compression of the spring 11, and accordingly the fierceness of the acceleration necessary for the mass 13 to open the valve 10, is adjusted by a screw 12. In another form, compressed air or oil under pressure is admitted through a port 25, Fig. 3, and through a valve 22 to a port 26 leading to a servomotor disengaging the main clutch, when the ratio shift lever is moved with consequential energization of a solenoid 20 causing an armature 21 to move against the bias of a valve-closing spring 23. On establishment of the newly selected ratio, the solenoid 20 is de-energized and the spring 23 shuts off the supply of compressed air &c. Pressure in the clutch disengaging servomotor is gradually reduced by compressed air &c. leaking out through the port 26 and an adjustable bleed-off hole 28. If, following establishment of a new ratio, the motor car throttle is opened to produce rapid acceleration, a mass 30 pivots to open a needle valve 32, through which the compressed air &c. pressure in the clutch disengaging servomotor escapes rapidly for quick re-engagement of the clutch.

Filed: 1960-09-01
Abstract: 993,551. Welding by fusion. BRITISH OXYGEN CO. Ltd. Aug. 24, 1961 [Sept. 1, 1960], No. 30182/60. Heading B3R. [Also in Division H2] In consumable electrode arc welding apparatus using a D.C. arc the electrode feed motor during welding is connectable either across the are or to a constant voltage D.C. supply. The constant voltage supply is derived from an A.C. source 14 through a transformer TR and a rectifier BR. Closure of push button IPB connects the feed motor 12 across the rectifier BR to inch the electrode at a speed determined by a resistor R1. Assuming that a switch CFS is closed, operation of the trigger switch TS energizes relay WSR to open the inching circuit, to actuate the argon valve ASV and to connect the feed motor 12 across the rectifier BR to feed the electrode at a speed determined by a resistor CFR. The welding circuit is closed by relay WC. When an arc strikes between the electrode 10 and the work 11, welding current relay WCR operates a slave relay SR, which locks up and connects the feed motor 12 across the arc or the rectifier BR in accordance with the pre-setting of a switch COS. In either case the feed speed is adjustable by a resistor WVR. The motor 12 continues to feed regardless of any shorting of the arc that may occur until the trigger switch TS is released. If switch CFS is initially open the feed motor is not tarted until the arc strikes.
