Title: Transmission assemblies
IPC: F16D55/02
Filed: 1972-08-07
Abstract: 1403017 Disc brakes; spring-applied brakes; electromagnetic brakes POTAIN 7 Aug 1972 [6 Aug 1971] 36795/72 Heading F2E The shaft 7 of a transmission assembly is mounted for rotation in a stationary casing and may be decelerated to a selected speed by an eddy-current brake 4, 6, 18 and braked completely by a spring-applied electromagnetically released disc brake 14, 21. The eddy-current brake comprises a stationary inductor 4 having a coil 18 and a bell 6 keyed to the shaft 7 for rotation therewith, and energization of coil 18 reduces the speed of rotation of bell 6 and shaft 7. In the embodiment of Fig. 1, the disc brake comprises a disc 14 axially slidable on a splined sleeve 15, keyed to the shaft 7 so that the disc 14 rotates therewith. An annular friction brake lining 13 is secured to the casing 11 on one side of the disc 14 and there is another annular lining 21 secured to a braking member 17 on the opposite side of the disc. The member 17 is free to slide axially but is prevented from rotating by spigots 19, 20 engaging in grooves in the casing 11, and to the member 17 is attached to an armature 16 by a screw connection. The armature 16 is acted on by a compression spring 22 which urges armature 16 to the right so that disc 14 is nipped between linings 13, 21. However energization of coil 24 in a yoke 12 attracts armature 16 leftwards to release the brake. In the embodiment of Fig. 3, not shown, the disc 14 is not axially slidable and braking is effected on one surface only by lining 21. Permanent magnets may be incorporated in the yoke 12, which makes it possible to obtain two stable positions for the armature 16 when the coil 24 is switched off. The shaft 7 is splined at 23 to receive the first pinion of a gear-box and is driven by belts 3 from a driving member, which belts 3 engage a pulley 8 keyed on shaft 7.

Title: Process for the separation of rare earths
IPC: C22B59/00
Filed: 1959-07-10
Abstract: Samarium and/or europium and/or ytterbium are separated in the presence of other rare earths in a process which comprises treating, in a non oxidizing atmosphere, an aqueous solution containing a divalent salt, for example the chloride, of at least one of the above three rare earths with ammonia, in the presence of sulphate ions, which may be added as ammonium sulphate, to form an alkaline suspension, the trivalent rare earths being precipitated as hydroxides and the divalent rare earths as sulphates, acidifying the suspension, for example with hydrochloric acid, to dissolve the trivalent rare earths, and then separating the divalent rare earth hydroxides precipitate from the solution.  The divalent salts may be prepared by reducing the trivalent salts by electrolysis or with sodium vapour.  If it is desired to recover europium by itself, the reduction may be effected with zinc amalgam, which reduces the europium only.

Title: Flash arrays
IPC: G03B15/04
Filed: 1975-09-09
Abstract: 1525727 Photographic flash units GENERAL ELECTRIC CO 9 Sept 1975 [30 Sept 1974] 37024/75 Heading G2X A circuit board for a multiple flash-lamp array has switching circuitry on one side for sequentially firing the lamps, and a conductive shield in the form of a film on at least part of the other side. The flash-lamp array (17) Fig. 1 (not shown) and the circuit board 36 are as described and shown in Specification 1525726. The shield 78 is a metallic film or foil, plated, printed, or otherwise provided on the rear side of the board, as seen in Fig. 4. This reduces the possibility of lamps being accidentally flashed by electrostatic voltage if a lamp connection terminal is touched by or brought close to a person or object having an electrostatic charge. Such flashing tends to occur particularly when high voltage low energy lamps are used in the array. The shield may be connected electrically to a leadin wire of each lamp, and to the lamp reflectors. The shield may cover the whole board, or at least coincides with the "hot" runs, that is, the circuit runs 81, 82 other than the common grounded circuit 76. The shield may be shaped to provide T-bars 86 and 86', extending laterally across the respective tabs 18, 18' by which the board is plugged into the camera or flash adapter socket, to increase the likelihood of discharging an electrostatic charge on the electrical ground.

Title: Improvements in and relating to gas shielded arc welding
Inventor: HALL ERIC THOMAS
IPC: B23K9/16
Filed: 1958-11-21
Abstract: 881,531. Control systems for welding arcs. ROLLS-ROYCE Ltd. Nov. 12, 1959 [Nov. 21, 1958], No. 37492/58. Class 38 (4). [Also in Group XXII] A process of gas shielded arc welding consists in supplying a welding torch with shielding gas, after a delay connecting welding and ionising current to the electrode to strike an arc without contact occurring between the electrode and the work, switching off the ionising current, when the weld is completed switching off the welding current and after a delay stopping the supply of shielding gas. When a manual switch e.g. on a torch having a tungsten electrode, or on a cabinet housing the controlling and generating equipment is actuated a relay 47 connects up solenoid-operated valves 51, 52, 53 to supply argon and water to the torch and if desired argon to the back of the weld. After a delay the welding current from a source 58 is switched on by a relay 57 and a relay 65 responding to the open-circuit voltage connects up a high-frequency generator 67. When the arc strikes the relay 65 disconnects the high-frequency generator 67 and a D.C. motor drives a variable resistance 72 to gradually increase the welding current to the full welding value. When the manual switch is released at the end of the weld, the D.C. motor gradually alters the variable resistance 72 to decrease the current to a predetermined value at which it is switched off. Finally the gas and water are disconnected. If desired the automatic current control by the D.C. motor can be disconnected, the welding current being set manually.

Patent GB-800249-A (GB)
Title: Improvements in or relating to absorption refrigeration
IPC: F25B43/04
Filed: 1956-12-11
Abstract: 800,249. Refrigerating. CARRIER ENGINEERING CO., Ltd. Dec. 11, 1956 [Feb. 14, 1956], No. 37883/56. Class 29 Relates to means for removing non- condensible gases from the absorbers of continuous cycle absorption systems which may be of the general type disclosed in Specifications 787,298 and 639,413 preferably controlled as described in Specification 698,309. According to the invention, a pump 79 withdraws solution from a container 75 and returns it thereto through an ejector 81 which induces gas flow from the absorber 3 through pipe 84, the gas bubbling through liquid in the container and escaping to atmosphere, and, when the liquid level rises in the container, the gas flow is stopped and excess liquid is returned to the absorber through pipe 84. The ejector is actually within the container although it is shown outside it in Fig. 1. The container is cooled by a coil 76 through which flows liquid refrigerant from the evaporator 4. To maintain the solution concentration in the container, a little solution is fed thereto from the absorber through pipes 91, 84. As shown, pipe 83 connecting the ejector discharge to the container contains a normally open valve 86 but, when the liquid in the container rises, a float 88 actuates a switch 87 to close the valve and the pump then returns solution through the ejector and pipe 84 to the absorber until the liquid level has fallen enough to allow valve 86 to open again. In a modified form, the container is pivoted in such a way that, when it gets too full, it tips up so that its bottom closes off the outlet of pipe 83, thus allowing the pump to return solution to the absorber. In further modifications, rise in level of the liquid in the container shuts off the pump and liquid is forced through pipes 83, 84 to the absorber by atmospheric pressure.

Abstract: 1369330 Feeding sheets SIG SCHWEIZERISCHE INDUSTRIE-GES 15 Aug 1972 [16 Aug 1971] 37969/72 Heading B8R Sheets 5 are piled in a magazine 2, Figs. 1 and 2, for separation from the bottom, and beside the magazine is arranged an assembly of arrest wheels 7, 8, connected by gearing to rotate in the same direction, the wheel 7 more rapidly. The wheel 7 has two pins 11 and the wheel 8 a plurality of pins 12 to engage into the side of the pile. In the position of Fig. 1, the upper part 4 2  of the pile is supported by the wheel 8, while the wheel 7 engages the lower part 4 1 . The weight of the part 42 acts through the wheels and a pin 11 on the lower part, but its effect is reduced by the gear ratio. As sheets 5 are separated from the bottom, the pin moves down slowly until it disengages the part 41 whereupon the weight of the part 42 causes rapid rotation, allowing sheets to drop from 4 2  to 41 as in Fig. 2, until the next pin 11 engages the pile. The wheels may have different numbers of pins, or the pins may be replaced for each wheel by a rim of resiliently deformable material, that on the lower wheel being interrupted. There may be more than one pair of wheels, arranged on more than one side of the pile. The wheels may be replaced by belts.
Patent GB-1486826-A (GB)
Title: Method for conducting surface immunological tests
IPC: G01N33/543
Filed: 1974-08-30
Abstract: Suitable substrates are coated with a monomolecular protein layer consisting of an immunologically reactive first protein and of an inert protein. The molecules of the first protein are moreover separated from each other by the molecules of the inert protein. The substrate with a monomolecular coating is contacted with a solution of an immunologically reactive, second protein which is specific for the first protein. This results in the second protein molecules binding to the first protein molecules to form a bimolecular layer on the substrate. In contrast to known substrates of this type, the second protein molecules show after formation of the bimolecular layer a larger number of active sites for another immunological reaction. In addition, when large first proteins are used there is in this way a significant increase in the contrast between the mono- and the bimolecular parts of the layer. The substrates with a bimolecular coating obtained in this way can be used for the detection and determination of various other immunologically reactive substances.
