Title: Segmental chill-casting mould
IPC: B22D11/041
Filed: 1975-02-06
Abstract: 1464075 Moulds; continuous casting VEREINIGTE EDELSTAHLWERKE AG 6 Feb 1975 [6 Feb 1974] 5057/75 Heading B3F A mould for electroslag remelting or for continuous casting is made of a number of segments 1, e.g. of copper, held against each other by two or more split rings 2, the ends 3 of each of which are pressed towards each other by springs, e.g. Belleville washers. The springs 3 of each ring are mounted on a bolt. There may be a curved-back spacer 9 between each segment 1 and each ring 2 or the segment backs may be curved correspondingly. The mould cavity 14 may be square or rectangular. The segment surfaces delimiting the cavity 14 may be curved. A carriage for the mould includes a horizontal plate 8 with an aperture 8<SP>1</SP> through which pass the segments 1. An angle bracket 10 bolted to each segment 1 is secured on a stud 12 in the plate 8. The studs 12 are received in radial slots 11 in the brackets 10 so that the parts 1 are displaceable to adjust for thermal expansion. Ducts 13 in the segments 1 are for cooling water and are closed at their ends, e.g. by screws. Connections for the inlet and outlet of water are at the outer sides of the segments 1.

Title: Improvements in or relating to machines organised for applying coating material to workpieces
IPC: A43D25/18
Filed: 1953-02-24
Abstract: A machine for applying coating material to workpieces comprises work feeding means, means for folding successive marginal portions of a workpiece as it is fed by the work feeding means, and means for delivering coating material during folding <PICT:0750613/III/1> which has a valve controlling the flow, and a member engaging the workpiece to vary the position of the valve according to variations in thickness of the workpiece.  The workpiece W is fed to a work support 10 by the action of a hammer 12 and anvil and is guided by gauge finger 14, the margin being folded by a folding finger 16 against a creaser foot 18 the workpiece being clamped beneath the creaser foot by a gripping member 20 movable downwardly to allow the workpiece to be fed as described in Specification 574,402.  Adhesive is supplied to the margin of the workpiece through a tube 52 of the creaser foot mounted for vertical movement in a support 22 carried by a plate 24 and bracket 26 on the head 28.  A plurality of openings at the bottom of the creaser foot are controlled by a valve 54, on a stem 74, which carries a gear 76, which meshes with another gear in mesh with a segment 80 retained against a stop 86 by means of a spring 84 so that the openings are closed.  The gear segment is connected by sections of a link 88 interconnected by a screwthreaded sleeve 94 to the plunger 90 of a solenoid 92.  The sleeve is rotatable to vary the length of the link 88 whereby actuation of the solenoid causes variable movement of the gear segment and varies the openings at the end of the creaser foot.  The sleeve carries a gear 96 meshing with a rack 98 carried by member 102 engaging the head of a rod 106 having collars between which is the end of a member 112 pivoted at 110 to the support 22.  Also pivoted at 110 is an arm 120 which has a slotted end, engaging a block 122 on a plate 30 secured to the creaser foot and detent adjustable by a knob 126 to engage apertures in the plate 112.  According to the aperture selected the member 112 is raised or lowered to vary the height of the rack 98 and vary the length of the limb 88 to allow one or more openings in the creaser foot to supply adhesive to the work margin.  If the thickness of the seam varies the supply of adhesive is automatically adjusted by lifting the creaser foot which affects the height of the member 112. The creaser foot is normally urged downwards by a spring 38 surrounding a rod passing through the support 22 and plate 30.  The creaser foot and gauge finger can also be raised by pressing members 42 and 50.

Title: Improvements in or relating to internal combustion engine ignition systems
IPC: F02P1/08
Filed: 1948-02-25
Abstract: 651,219. Ignition systems; timing ignition. BRITISH THOMSON-HOUSTON CO., Ltd. Feb. 25, 1948, No. 5643. Convention date, Feb. 27, 1947. [Claas 7 (iv)] [Also in Group XXXV] In an internal - combustion engine ignition'system comprising a magneto (see Group XXXV), for producing periodic voltage impulses in output means, such as the generator coils 10, the output means being connected to a circuit containing a plurality of condensers 16, 17 to be charged by the magnetos in such a manner that a voltage impulse from the .magneto charges one of the condensers and a later impulse charges another condenser, the condensers 16, 17 are connected in series and in circuit with rectifier means 22, 24 so that the individual condenser voltages are additive, the condensers being simultaneously discharged periodically through an ignition circuit including a distributer 26 synchronized with the magneto. The ouptut from one of the two coils 10 of the generator, which is of the inductor type, is led by one lead 19 to a common terminal 18 between the condensers 16 and 17, the condenser 16 being connected to the other output lead 21 through the rectifier 22 whilst the remaining terminal 23 of condenser 17 is joined to lead 21 by means of a parallel circuit that includes rectifier 24. Terminal 23 is also connected to the moving contact of the jump spark distributer 26 each of the fixed distributer contacts being connected to a spark plug 33 through a step-up transformer, 30, one of which latter may be hermetically sealed in each plug. The alternating voltage from one coil 10 charges firstly one then the other condenser whereupon their voltages are additive and both condensers discharge together in cascade to produce a high-frequency operation of a selected sparking-plug 33. Since a circuit breaker is not used, timing adjustment is obtained by an appropriate circumferential spacing of the fixed distributer electrodes. Each coil 10 has a separate distributer with fourteen fixed contacts and by displacing the moving contact of one dstributer by an amount equal to half the distance between adjacent fixed electrodes then it is possible to supply ignition for a twentyeight cylinder engine, alternate plugs being fired from the same distributer. However, if there is no displacement of one moving contact with respect to the other then it is possible to supply dual ignition for a fourteen cylinder engine. The generator is driven at one-half engine-speed irrespective of the number of engine cylinders. The condensers 16 and 17 may either be of the same capacity or have a capacity ratio of 4:1; in the latter case it is arranged that the condenser receiving the first charge in each charging cycle has the larger capacity. Instead of a two-impulse charging cycle any number of impulses per cycle could be used. A contact-type distributer connected directly to the plugs is used if a high-frequency system is not required. Specification 651,223, [Group XXXV], is referred to.
