Title: Crystal growing
IPC: C30B11/00
Filed: 1973-03-12
Abstract: 1415549 Single crystals PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES LTD 12 March 1973 [15 March 1972] 11764/73 Heading B1S In a process of growing a single crystal e.g. a rod, by passing a mass of the liquid to be crystallised contained in a hollow cylindrical enclosure through a similar shaped zone heated by radiation and containing therein a steep temperature gradient, heat is dissipated by connecting to the enclosure a body of revolution coaxial with it and wherein the coaxial thickness of this body on the circumference is larger than in the region around the interior longitudinal axis and wherein the material of the body of revolution has thermal properties identical with or approach those of the liquid to be crystallised. A seed crystal may be present. The body of revolution may be a liquid mass in a container which constitutes a double bottom in the cylindrical body, or a solid provided at one end of the cylindrical body, or a disc which can be pressed on the cylinder body. The crystal may be gallium phosphide. As shown in Fig. I, a cylindrical enclosure I which terminates in a conical part 2, contains liquid 4. Radial thermal energy is denoted by arrows 3 and a liquid or solid body is connected to 1, and has a less height at the centre than on the circumference. The crystallisation begins at the tip of the cone. In the process, body 5, causes isotherms e, f, g, which are convex towards the solid in contrast to the isotherms shown in broken lines which would occur in the absence of body 5. Figure 6 shows a modification wherein the bottom 54 of cylindrical enclosure 51, has a concave conical shaft which contains a liquid 52 from which crystallisation is effected. A seed 53 of same diameter as the inner diameter of 51 and which adjoins the bottom 54 is provided in the liquid and provides the body of revolution. Thermal dissipation is provided by rod 56 in contact with bottom 54. Crystallisation occurs on face 55 of the seed.

Title: Improvements in or relating to electric cigarette lighters
IPC: F23Q7/00
Filed: 1948-04-30
Abstract: 656,481. Machines with permanent magnets. SZARVAS, F. April 30, 1948, No. 11850. Convention date, Aug. 12, 1944. [Class 35] [Also in Groups XI and XXIV] An electric generator incorporated in a cigarette lighter comprises a cylindrical steel rotor with N and S magnetic poles disposed alternately on its face and a stator comprising two coils 41 with laminated iron cores 40 of horseshoe shape joined at top and bottom by metal pieces 42, 43. The cylindrical rotor is connected to its axle 14 by a web 45 and by fan blades 44 which drive air upwardly through conduits in the upper bearing 47 of the axle on to a filament energized by the generator and serving to light a cigarette. The lower end of the rotor axle 14 is located in a bronze-lined bearing hole 46 in a driving axle 26 to which the rotor is connected by a magnetic clutch comprising ratchet teeth 32 on the top end of the driving axle and pawls 33 disposed in a cylindrical housing 35 formed by windening the lower end of a tube 34 pressed into the bore of the rotor. The two pawls are held and guided by metal brackets 37 and curved ribs 38 and the driving axle is magnetized to draw the pawls into engagement with the ratchet teeth. The driving axle 26 is driven by a spring 29 which is attached to the upper end of the axle and has its lower end disposed in an elongated metal housing 30 which is free to move laterally inside, and is carried rotatively with, a flat handle 20 rotatably mounted on a cylindrical extension 16 of the generator casing. The handle 20 is rotated manually to wind up the spring 29 and at each half revolution two spring-urged bars 22 slidable in the handle engage ratchet depressions in the generator casing to prevent unwinding. During winding the driving axle is connected by the clutch to the rotor axle which is prevented from rotating by a flat spring abutting one of two lugs on the rotor. By pushing a button 57 on the flat spring along a slot 58 in the generator casing the rotor is freed and both axles then rotate together under the action of the spring 29. Centrifugal force eventually causes the pawls to disengage from the ratchet teeth so that the rotor continues to rotate after the spring is completely unwound and the driving axle is again stationary. The Specification as open to inspection under Sect. 91 also states that the pawls 33 are made partly of a non-magnetic material such as brass or copper and partly of magnetized steel. This subject-matter does not appear in the Specification as accepted.

Abstract: 572,009. Pneumatic material-handling system. BRITISH THOMSON-HOUSTON CO., Ltd. July 21, 1943, No. 11870. Convention, date, July 21, 1942. [Class 78 (i)] [Also in Group XXXV] A system for the pneumatic disposal of dust, ash &c. comprises a plurality of containers 50-61 having a common discharge conduit 62 under suction, discharge valves 50a-61a for each container, and an electric selector switching device responsive to pressure changes in the conduit to operate the valves in sequence; The conduit 62 leads to a collecting chamber 63 which when full is automatically emptied into a bin 92. The hoppers are arranged in groups A-D and the valves of each group are operated by cams on common shafts 68-71 turned step by step by ratchets 72 with electrohydraulic operating means 76 controlled by relays 76a connected to the selector switch 81. This switch is described in detail in the specification and comprises wipers operated step by step over banls of contacts by an electrically operated ratchet under the control of a manually operated master switch, and a vacuum relay 86 in the conduit 62, When the master switch is turned to the start position the wipers are moved by the ratchet to the first setof contacts energising relay 76a to open valve 50a connecting the first hopper with the suction conduit 62 and also opening an air inlet port in the valve. Simultaneously a motor 103 is started to vibrate a flexible plate 99 in the hopper 50 to agitate the dust. The vacuum relay 86 then causes the wipers to move to the second set of contacts, after a predetermined time governed by a time delay relay in the switch 81 causing the ratchet 72 to move to the next notch. As soon as the hopper 50 is empty the loss of vacuum, in the conduit 62 causes the relay 86 to move the wipers to the third position and the ratchet 72 is moved, to' turn the shaft 68, closing the valve 50a and opening the valve 51a of hopper 51. Simultaneously the vibrator 99 in the hopper 50 is stopped and the vibrator in the hopper 51 started. The sequence of operations continues until all the hoppers have been emptied. When the collecting chamber 63 is full a switch 89 sensitive to the level of material in the chamber operates a dumping valve 91 and interrupts the emptying of the hoppers 50-61. to prevent skipping of hopper due to the loss of vacuum on the opening of the valve 91. The manual switch is provided with contacts to re-start the operation if stopped due to one of the hoppers 50-61 being empty.
