Title: Apparatus and method for moulding cup-shaped bodies
IPC: C03B19/06
Filed: 1962-08-09
Abstract: <PICT:1007182/C1/1> <PICT:1007182/C1/2> <PICT:1007182/C1/3> Cup-shaped bodies having wires passing through the sides are pressed from granular material, e.g. powdered devitrified glass, in a mould comprising a die block with a vertical bore and grooves leading into the bore to accommodate the wires, and means to hold the wires having a bore, of the same diameter as the die, which forms part of the mould cavity. The mould cavity (Fig. 1) is defined by the die block 1 which has grooves 4 for the wires 30, the plate 20 which holds the wires, a core 5, a plunger 6 surrounding the core 5, and a plunger 24. The core 5 is held level with the grooves 4 (Fig. 3) by a piston and cylinder 8 and is positioned by a nut 9.  During compression, in which the plunger 24 is lowered and the plunger 6 may be raised, the core 5 may move downwards by an amount determined by the initial position 13 (shown dotted) and the final position (shown full line) of the nut 11 so that the wires are bent as shown in Fig. 4.  The initial position of the plunger 6 is adjusted by the nut 15 and the stop 32 and the plunger 6 is raised during compression by the nut 25 and the arm 26 of a cam and lever arrangement (not shown) and is raised to eject the moulded cup by the nut 27 and arm 28.  The cup may be used for housing a semi-conductor device.  Specifications 909,660 and 991,940 are referred to.

Title: Device for manufacturing a non-woven reticulate textile strip
IPC: D04H3/04
Filed: 1973-06-27
Abstract: 1415975 Filamentary laminates W F JENSE 27 June 1973 [7 July 1972] 30591/73 Heading B5N [Also in Divisions D1-D2] An apparatus for making a non-woven net and laminating it to sheets 11, 12 comprises conveyers 1, 2 which are parallel over some or all their lengths the conveyers bearing hooks 3 pointing in the direction of travel with their hooked ends pointing downwards, there being no part of each hook projecting outwards with respect to the points at which it is fastened to the conveyer, and at least one thread layer 5. Preferably the hooks 3 are inclined inwardly, i.e. towards the other conveyers. A pivoted rod 4 carrying thread guides 8 is reciprocated through an arc to lay the threads in a crisscross fashion. Warp threads 13, 14 and sheets 11, 12 may be calendered on to the transverse threads which are then cut loose of the hooks by rotating cutters 16. In the embodiment of Figs. 8, 10 the net is modified so that the transverse threads are perpendicular to the warp threads. Each thread passes round a hook, leaving a gap (23, Figs. 6, 9, not shown) equal to the diameter of the hook between the lower outgoing portion of the thread and the upper returning portion. A tapered space 25 increases this gap and facilitates cutting of the upper (or lower) thread portion close to the hooks on conveyer 1. A resilient ganged belt 24 presses against the hooks on conveyer 1 to clamp the threads against slipping. Conveyer 2 is directed away from conveyer 1 to double the width of the net and render the threads perpendicular to the conveyers. A glass bar 29 contacts the hooks on conveyer 2 and applies sufficient friction to keep the threads taut.

Abstract: 174,719. Popovatz, P. Oct. 29, 1920. Propelling by air and water jets.-Relates to reaction propelling apparatus for marine or aerial vessels of the internal-combustion type and consists in fitting the explosion chamber with multiple feeds for the fuel which is vaporized in a reservoir in the chamber, in providing large flat valves between the chamber and external fluid acted upon, in providing multiple air inlets to the chamber, and in mechanically or hydraulically operating and controlling the various valve members. The explosion chamber A has an extension B, Figs. 1, 8, and 10, containing the fluid to be acted upon and has a division member C with quick-acting grid valves g. Fuel is introduced to a central perforated tube a through radial pipes b having valves b<1> and connected to two vaporizers d. The supply to pipes e of the vaporizers is obtained from a constant-level tank. Air is admitted to the chamber by valves f. For starting up, an air pump is employed. The valves b<1> are actuated by rams b', the rods g<4> of the disc valves g by rams g<3>, and the valves f< >by rams f<1>. The actuation of these rams in their correct cyclic order is effected by valves such as H1, Fig. 9, in the pipe lines, these valves in turn being operated by rams such as I1, which are operated by pump members such as K, driven by eccentrics such as L1 on a " timing " shaft. Four storage vessels 1, 4, 10, 40 under pressures of 1, 4, 10, 40 atmospheres are variously connected up, as indicated, to differential pistons of the rams and to control valves. Preliminary heating of the fuel may be effected in a coil E forming a shunt in the fuel inlet system. The fuel mixture is not compressed before ignition.

Abstract: A jet loom (Figs. 1, 3, 4, not shown) has a picking device comprising a tube 4 in. the shape of a loop, hauling an inwardly directed slot 7 in the area bounded by the loop and having plates 8, 9 that enclose the loop and slot 7.  In operation air is admitted to the tube at A and a thread clamp 2 is opened so that the weft F is carried around the tube until it reaches a photo-electric device 13 which operates to close the clamp 2 which is fully closed when the weft reaches the exit E of the tube. Continued admission of air with the clamp 2 closed causes the weft to traverse between the plates 8, 9 until it extends directly between the inlet 6 and exit E and is fully picked into the shed. A cutter 14, at the exit E, is then operated and a hook 17 is swung to the dotted line position taking with it the weft end which then lies wholly in the first portion of the tube ready for the next pick.  A collar 24 may be slid around the tube to partially block the slot 7 and control the length of pick.  A second embodiment (Figs. 5 to 7, not shown) uses a double-coiled tube 35 with butterfly-value controlled air admission and has a weft feeder comprising rollers 31, 32 which feed the weft over a cooperating portion D to E and have a cam 44 and recess 45 with withdraw the yarn after severence, in place of the hook 17 of the first embodiment.

The tubes are of quartz, either translucent, transparent or black. The resistor 6 is a metal of small thermal expansion and may be tungsten, molybdenum, tantalum or niobium or an alloy of these, and may be a straight, undulating, spiral or coiled spiral wire. The tubes are supported near their ends by ceramic rings 3 secured to a reflector 9 by screws 5 and are in a bundle with darker tubes at the rear of more transparent tubes. The radiation at 1000‹ C. is of 2.3Á wavelength and longer and a tube of 8 mm. diameter may carry a load of 1 kw. per metre. The ends of the tube are sealed by a putty adapted to the thermal expansion of the tube. Stranded cable wires 8 pass through the seal and are welded to the resistor, the outer ends of the conductors 8 being connected together, conductively if required, to form a cable. The tubes may be evacuated or filled with a preferably inert gas, and the end seals may be not entirely hermetic. Each tube may have zones of different transparencies, the rear side being less transparent than the front. The tubes may be connected in parallel, but an adjustable series resistance may be placed in the supply to each tube; or the tubes may be connected in series so that with an even number of tubes, current, is supplied at one end only of the radiator; or the connection may be switched from series to parallel. A polyphase A.C. may be used, and three tubes may be connected in star or delta. Specification 695,507 is referred to.
