Title: Improvements relating to Electrical Connectors.
Inventor: STEPHENSON CONSTANTINE DEAN
IPC: H01R24/86
Filed: 1967-06-19
Abstract: 1,170,172. Two-part couplings. BUNKERRAMO CORP. 19 June, 1967 [20 June, 1966], No. 28230/67. Heading H2E. In a multi-contact connector individual contacts of both the plug part and socket parts are firmly held in the part yet readily removable. Each contact 12 is formed with a rack portion 16 and is held in a bore 22 in a dielectric body 20 by a radially expandible sleeve 24, which may be integral with the body 20 and split longitudinally for added resilience, engaging the neck portion 16, shoulders 14 and 18 resisting axial movement. The contact 12 may be removed by applying a large axial force to expand the resilient sleeve 24 over the shoulder 18. Locking member 28 has one end of the bore 30, which receives the contact 12, widened to extend around the sleeve 24 to stop radial expansion of the sleeve and thus prevent axial removal of the contact 12. The dielectric body 20 and locking member 28 are held in engaged position by co-operating threaded rings 38 and 40 which have shoulders 37 and 41 which force the two members 20 and 28 together. A soft rubber sealing gasket 32 is located between the body 20 and locking member 28. In an alternative embodiment the main body and locking member are urged together by a centrally located screw. Guide pins 52 may be provided to ensure correct polarity of the contacts and locking member. External connections to the contacts 12 pass through the soft sealing grommet 34. The plug and socket parts of the connector are joined by bayonet coupling 54 with 0-ring 58 and gasket 56 ensuring watertight seal between the two parts.

Patent GB-908999-A (GB)
Title: Improvements in machines for sorting and counting coins or similar articles
Inventor: RAND LEONARD ALEXANDER
IPC: G07D3/06
Filed: 1960-08-16
Abstract: 908,999. Separating coins. INTERNATIONAL COIN COUNTING MACHINE CO. Ltd. Aug. 16, 1961 [Aug. 16, 1960], No. 28435/60. Class 27. [Also in Group XIX] A coin-counting machine comprises means to sort the coins according to size, means for determining both individual totals of each type of coin and a running total of all the coins and means for stopping the machine when a predetermined total of any one type of coin is reached. The coins are sorted by a rotating plate of two layers 1, 2, turning on a fixed plate of two layers 3, 4, and, after falling through holes 5 of a size to admit the largest coin without allowing two of the smallest coins to be side by side, fall into traps 6 arranged in increasing order of coin size. Each coin in its corresponding trap tilts and is forced past a star-wheel 8 by a projection 7 on the layer 2 until it falls into a container through a hole 9. For each starwheel, a chain drive transmits the step-by-step movements to a counting unit totalling the number of coins of a given denomination and to a sprocket 13. Each sprocket 13 drives a camplate 26 within a housing 24 and a second plate 25 on a cross-shaft 22 concentrically rotatable within the housing carries a pawl 27 engageable by the cam-plate so that, when a coin causes rotation of a sprocket 13, the camplate releases the pawl from one of several teeth on the housing and allows the shaft 22 to be rotated until the pawl meets the next tooth. Power for this rotation is supplied by a monitor shaft 4 having a slipping clutch driven by a motor 18 and a chain drive to a sprocket 21. The chain also drives, through slipping clutches, a pair of shafts 40, 42, connected to the cross-shafts 22 through a differential mechanism. The shaft 40, by means of gearing between the cross-shaft and the differential train to compensate for the varying value of coins, totals the value of the coins and the shaft 42 totals their number. As the slipping clutch tends to drive the differential train and cross-shafts much faster than the star-wheel allows, the simultaneous operation of several star-wheels will be added by the differential train. Each cross-shaft 22 has an eccentrically-driven pawl which advances a ratchet-wheel step-by-step and after a predetermined rotation of the wheel a cam-disc opens a switch to stop the motor and apply a brake.

A fertilizer-distributer comprises a hopper 22 from which material is fed to two partiallyoverlapping vaned discs 19, the material being fed off-centre so that it will tend to be ejected over a pair of overlapping sectors of distribution, the densitygradients of which are opposed to one another. The hopper has tapering walls leading to a trough wherein a pair of paddle-wheels 30 eject the material through apertures controlled by adjustable shutters 27. The machine is mounted on land-wheels 34 driving half-shafts 13 to which the axles 16 of the vaned discs are connected by bevel gears 14, 15, one of the wheels also driving the paddle-wheel axle 28 by a beltdrive 31. In a modification, the device is wholly mounted on tractor draught-links through connections 35 on the chassis 10, the wheels 34 being then omitted and the halfshafts 13 being interconnected by a shaft 36. The drive is taken from the tractor powertake-off by a jointed shaft 37. The off-centre feed results in an asymmetrical density distribution in the ejected stream but by overlapping two streams a substantially uniform spread is obtainable. The distribution-overlap may be produced either by arranging the discs at different levels, as shown, or by tilting them relatively to one another. According to the first Provisional Specification, a screen, W- shaped in plan, may be mounted in front of the spreaders to ensure rearward distribution.

Title: Improvements relating to fuel cells and methods of producing electrodes for such cells
IPC: H01M8/14
Filed: 1958-09-10
Abstract: 850,706. Fuel cells. NEDERLANDSE ORGANISATIE VOOR TOEGEPAST-NATUURWETENSCHAPPELIJK ONDERZOEK TEN BEHOEVE VAN NIJVERHEIDE, HANDEL EN VERKEER. Sept. 10, 1958 [Sept. 12, 1957], No. 29058/58. Class 53 A fuel cell has an electrolyte 1 which may be a solid produced by melting an alkali carbonate or a mixture of carbonates, or alternatively it may consist of a porous carrier, for example magnesium oxide, impregnated with carbonates. On each surface of the electrolyte is an electrode in the form of powder which is in contact with a sheet of metal gauze 4, 7. The two sheets of gauze are pressed against their respective powder electrodes by perforated plates 5, 8 which may be of metal or insulating material. Terminals 6, 9 are attached to the plates 5, 8 or to the gauze sheets 4, 7, and the various elements are separated by insulating washers 17 and enclosed between cover plates 13, 14 held together by screws 15. Fuel gas, e.g. carbon monoxide enters through pipes 16, and air or oxygen through pipes 18. The fuel gas electrode, or anode, may consist of powdered iron, copper, silver, gold, chromium, manganese, or metals of the platinum group. The metal powder may be prepared by reduction of the oxide or other compound by hydrogen, carbon monoxide or methane, and it may be attached to the surface of the electrolyte by an adhesive, e.g. water glass. The cathode may consist of silver, gold, nickel or a metal of the platinum group. An electrically heated furnace is also described enclosing a number of fuel cells connected partly in parallel and partly in series, the heat developed in the cells being used to maintain a constant temperature in the furnace. For this purpose the furnace encloses a thermocouple connected to an amplifier which actuates switches to cut off the heating current when the required temperature has been reached. The exhaust gases from the cells are passed through a heat exchanger which is used to pre-heat the fuel and oxidizing gases. If the temperature in the furnace rises too high, valves are operated to divert the exhaust gases from the heat exchanger and allow them to escape into the air. The fuel gases passing into a group of cells joined in parallel must have the same composition, and the exhaust gases which are not entirely converted are mixed in a manifold and fed to a second group of cells joined in parallel with one another and in series with the first group. The exhaust gases from this group are fed to a third group joined in parallel and in series with the second group.

Title: A device for remote indication of the setting of flow control valves, such as butterfly loading valves on board tankers
IPC: F16K37/00
Filed: 1964-07-15
Abstract: 1,022,180. Valves. O. KRACHT, J. KRACHT, and L. KRACHT. July 15, 1964 [July 16, 1963], No. 29180/64. Heading F2V. [Also in Division G3] The setting of a flow control valve actuable by an hydraulically operable drive means 19 controlled through two operating lines 9, 10 is indicated on a pressure gauge 5 connected to the outlet port 11 of a valve 52 actuated by the flow control valve through a spring 53, the valve 52 being connected to the operating lines 9, 10 through an automatically actuated valve 35 and having leakage flow conveyed to a discharge line 12. In the preferred embodiment, two butterfly loading valves 1 in an oil tanker are connected through separate control valves 4 to a common supply unit 6, the valve 52 for each loading valve being connected to a separate pressure gauge 5. Each loading valve has a pinion 20 meshing with a rack on a piston 19 which may move the valve to fully open or closed positions or be held at any intermediate position by actuation of the corresponding valve 4. To ensure that pressure is maintained at an adequate level in the supply to the valve 52, fixed throttles 42, 43 are provided in the supply to opposite sides of the piston 19. When the valve 4 causes a reversal of the pressure differential in the supply to the piston 19, it also displaces a piston 28 to open one of a pair of valves 26, 27, the other valve being opened directly by the increased fluid pressure. The shuttle valve 35 automatically closes the connection between the exhaust side of the piston 19 and a supply line 38 leading to the valve 52. A cam 54 on the pinion 20 displaces the latter through the spring 53 to cause a change in pressure in the outlet 11 corresponding to the position of the butterfly valve, the change in pressure also acting through a port 56 to restore the valve 52 to its original setting against the action of the spring 53. The valve 35 may be replaced by a pair of non-return valves and it may be supplied through a pre-set flow regulator while a relief valve may be combined with the valve 52.
