Title: Plunger valves
IPC: F16K3/28
Filed: 1974-03-29
Abstract: 1409997 Valves INDUSTRIE-EN HANDELSONDERNEMING CONVAL NEDERLAND BV 29 March 1974 [30 March 1973] 14107/74 Heading F2V In a screw-actuated plunger valve the plunger 3 is made of rubber and it has a dome-shaped end to engage in a similar shaped depression 4 in the wall of a through passageway 2 in a body part 1. The plunger is carried by, and free to rotate around, a retaining pin 17 rigidly fixed to a screw-threaded operating stem 8. The end of the pin 17 is also domed and in open positions of the valve is withdrawn a small distance from the end of the plunger but when the valve is closed it abuts the depression 4 to limit deformation of the plunger. Washers 19, 20 are provided between the plunger and the pin 17. The end of the stem 8 is piston-shaped and an O ring 14 is provided in a groove 13. When the valve is open the upper face of the piston part forms a metal-to-metal seal with a shoulder 16 in a head piece 5 screwed into the body. A skirted handle or wheel 9 is fixed to the operating stem 8 by a cross pin 10. The plunger may be made of an elastomeric material inert to gas or water and the body parts may be formed by hot pressing of brass material: the handle may be moulded from synthetic material.

Abstract: 349,757. Recording sound. SOC. FRANCAISE CINECHROMATIQUE(PROCEDES R. BERTHON), 24, Rue de la Pepiniere, Paris. May 8, 1930, No. 14229. Convention date, May 10, 1929. [Class 40 (ii).] Sound is recorded on a travelling transparent support coated with an opaque plastic material by a stylus or scraper of definite width which is vibrated transversely to the movement of the support by a diaphragm influenced by the sounds or electro - magnetically by sound currents. A photographic print is then made from the record on to a separate carrier or on to a carrier receiving black and white or coloured pictures, and the sound is reproduced photo-electrically by known means. The Figure shows a film A of celluloid, viscose, &c., coated with an opaque layer of a substance of wax consistency or of lampblack which is removed by a stylus or scraper B vibrated by a sound-influenced diaphragm C to form a wavy trace on the travelling film. This trace is used as a negative, and a positive is produced therefrom by masking the edge of the trace and copying photographically by contact printing or projection on to another film which may carry pictures or may be traversed in synchronism with a picture film during reproduction by photoelectric means.

Title: Improvements in magnetic brakes
IPC: F16D65/14
Filed: 1945-06-14
Abstract: 593,333. Brakes. PRECISION DEVELOPMENTS CO., Ltd., and OLAH, G. June 14, 1945, No. 15174. [Class 103 (i)] In a magnetic friction brake, the operative air gap is automatically restored to its original value after a predetermined amount of wear has taken place. As shown, braking is effected frictionally between a rotary member 3 and a normally stationary member 7, the member 3 being integral with a sleeve 34 on the motor shaft 4 and secured by rivets 5 to an armature 6 separated by an air gap 8 from an electromagnet having coils 2. A spring 3a tends to disengage the brake. The member 7 is secured by pins 18 to a member 9 carried by a shaft 10 which is threaded into a nut 12 on the backplate of the housing 1. The member 7 is normally held against rotation by pawls 14 engaging an internally ratchet-toothed surface 13 of the member 9. The pawls 14 are spring-loaded and are so formed that whilst rotation of the members 7, 9 is prevented in the direction which, by virtue of the screw-mounting 11, 12, diminishes the air gap 8; rotation is permitted in the other direction when the brake becomes too fierce owing to the lessening of the air gap through wear of the members 3, 7. The permitted rotation of the members 7, 9 thus increases the air gap to its original value. In a modification, the sleeve 34 engages with a bellcrank lever carrying a pawl which works over teeth on a ratchet face on a gear wheel meshed with a wheel on a screw shaft corresponding to the shaft 10. When wear exceeds a certain value, the pawl rides over one tooth and, on release of the brake, the shaft 10 is correspondingly rotated.

A spring, such as a spring washer g, mounted upon the spindle c presses the discs together and is adjusted solely by the screw thread c<2> and nut h provided on the spindle for the attachment thereto of the link. In a modification, a spring washer, plate spring, or helical spring is interposed between the inner disc and the spindle bearing tube, and is similarly adjustable by movement of the link upon the spindle.

Abstract: 630,300. Washing granular materials. NORTONS (TIVIDALE). Ltd., TAYLOR, F., BROWN, J., and NORTON R. M. June 10, 1947, No. 15295. Divided out of 624,093. [Class 82(ii)] In a jig for washing coal &c. in which the reject portion flows through an opening 13 and the resistance to flow through such opening is opposed only by a head of water and reject material in a compartment open at all times to the atmosphere, this head is varied by the action of a float 86 working in the bed of stratified coal &c. The invention is described as particularly applicable to jigs of the type described in Specification 624,093. Reject material passes through the opening 13 under an adjustable weir 12 into the reject compartment 8, and thence over a weir 21 into the disposal chamber 20, the chambers 8 and 20 being open to the atmosphere. The values (e.g. coal) flow along a trough 17 which passes through both said chambers but does not extend laterally as far as the sides of the cistern. The head of water in the chambers 8, 20 is controlled by the float 86 whose vertical motion raises or lowers one end 95 of the flexible outlet tube 85, the other end of which passes through the wall 57 of the disposal chamber to empty into the trough 17. The float 86 may be weighted to work on the reject stratum, (Fig. 1), or in the clean fraction. (Fig. 2). In the modification shown in Fig. 2 the float controls an annular weir 98 attached by a flexible annular diaphragm 104 to a tube 96 surrounding an opening in the bottom of the trough 17.
