Title: Ventilated radio-shielded spark plug
IPC: H01T13/16
Filed: 1944-03-30
Abstract: 579,298. Cables ; two-part couplings. BYRNE, E. L. W. (Titeflex, Inc.). March 30, 1944, No. 5915. [Classes 36 and 38 (i)] [Also in Group XXVII] A radio-shielding chamber surrounding the coupling between a sparking plug and the lead thereto comprises a tubular member 14 and a sleeve 24 arranged so that gas from the chamber passes under the sleeve and up a space 27 to reach a vent 28 in the member 14. The member 14 is screwed into an extension 13 of the plug and attached by a flanged nut 15 to a tubular elbow 6 containing the electric lea'd. The sleeve 24 is formed of insulating material, e.g., two mica cylinders clipped together by an annular member 26. The electric coupling comprises a split clip 22 which springs over a globular head 23 of the central electrode of the plug. The gas described is compressed air which, after passing down to elbow 6, to reach the chamber escapes through notches 26 at the base of the sleeve 24 or by the rough edge thereof. The vent 28 is controlled as described in Specification 579,308, by a valve 29 mounted on a bi-metallic strip surrounding the chamber 14, by a trapezoidal or rectangular ring made of a metal having high thermal expansion, or simply by a light flat coiled spring. The air is supplied through a chamber surrounding the magneto or distributor and a harness to which the elbow 6 is connected.

Title: Closure lining machines
IPC: B29C61/00
Filed: 1973-02-07
Abstract: 1454771 Moulding container closure linings W R GRACE & CO 6 Feb 1974 [7 Feb 1973] 5948/73 Heading B5A A device for feeding plastics composition to container closures for the formation of a moulded liner in each closure includes a rotary turret 3 supporting a number of circumferentially spaced pellet carriers 23, Fig. 2, which move along a closed path, means 5 for supplying a solid pellet of plastics 6<SP>1</SP> to each carrier, and means for feeding closures round the turret such that the closure and carrier paths are directly above one another during the transfer of pellets from their carriers to the closures. The closures are fed to the turret by a star wheel 2 and the pellet-containing closures are delivered to a star wheel 4 from which they pass via a heating stage to a moulding stage; alternatively the closures may be heated at a position upstream of the wheel 2. The means for supplying pellets include roller 7, 8 which intermittently feed a rod 6 of plastics material upwardly; a rotary cutter 9 cuts off the end of the rod to provide a pellet which is received by a slot in the lower end of a carrier. Each carrier is moved vertically by roller and cam means as the turret rotates so that it is lowered to receive a pellet, raised to allow the feeding on to the turret of the closures, lowered to deposit the pellet and raised to permit closure discharge. Each carrier includes a pin 31 extending therethrough, each pin being movable vertically independently of the carrier by cam and slot means whereby the pin can separate the pellet from the carrier and hold the pellet in position in the closure whilst the carrier is raised. The rollers 7, 8 are clutched, whereby the positively, intermittently driven one enables the other to free wheel in the opposite direction. A unit 15 senses the absence of a closure and a solenoid 17 is not activated to urge the rollers together so that a spring 18a is enabled to separate the rod 6 and roller 8 from the driven roller and interrupt the rod feed.

The threads f are more numerous than and consist of different material from the ordinary crossing pile threads a which are used for forming short tufts a<1>. To facilitate drawing out the floats, blind shots may be introduced under the parts f The Specification as open to inspection under Sect. 91 (3) (a) describes a modification shown in Figs. 5 (Cancelled) and 6 (Cancelled) where in the threads f only float behind the parts g<1>, g<2>, so that after cutting the fabrics apart, both long tufts f<2> and short tufts f<3> are formed. This subject-matter does not appear in the Specification as accepted.

Title: Improvements relating to the production of moulded cellulose articles
IPC: B29C67/00
Filed: 1920-03-02
Abstract: Articles of pure cellulose are obtained by applying a plastic sheet of cellulose hydrate to a metal mould, heating to 60-100 DEG  C. to dehydrate the material and at the same time dilate the mould, and finally cooling the uncovered portion of the mould to contract the mould away from the article.  The cellulose hydrate is obtained from viscose or other cellulose derivatives by ordinary methods. Imitation tortoiseshell or ivory articles are obtained by applying suitable substances to the material or to the sheets and the cellulose may be rendered impermeable if desired. The application to boxes and box linings is described.

Abstract: 783,985. Nuclear reactors. STITCHTING REACTOR CENTRUM NEDERLAND. March 7, 1955 [March 8, 1954], No. 6645/55. Drawings to Specification. Class 39(4). In a nuclear reactor, a suspension of solid fissile material in a moderating carrier liquid e.g. natural or enriched uranium articles in common or heavy water, is circulated continuously downwards through a vertical cylindrical chamber. The suspension is passed from the base of the chamber, through a heat exchanger, to a return system connected to nozzles at the upper end of the chamber by gas injected between the return of the heat exchanger as described in Specification 755,495. The suspension is diluted after leaving the heat exchanger to facilitate the recycling as described in Specification 757,015. Turbulence in the suspension is suppressed by certical partitioning in the upper part of the chamber. Vertical circulating currents are counteracted by introducing a small rotary motion round the longitudinal axis of the chamber by inclining a section of the partitioning. To increase the concentration of fissile material towards the chamber periphery some of the nozzles may be directed tangentially.
