Abstract: 942,765. Laminates. STEPHENS BELTING CO. Ltd. Feb. 27, 1961 [Sept. 24, 1960], No. 32897/60. Drawings to Specification. Heading B5N. A laminated conveyer or driving belt comprises a base layer of material suitable for frictionally transferring the drive, and one or more layers of tension reinforcing members which are ribbons or tapes of tough and flexible synthetic plastic material, e.g. nylon or polyester, arranged in substantially side-by-side contact across the width of the belt in each layer as a series of laterally adjacent helical turns or strips extending along the length of the belt at a bias angle to the longitudinal axis thereof, the components of the whole structure being mutually bonded together by an adhesive. The bonding of the components may be assisted by perforating the ribbons and tapes. The ribbons &c. may be so shaped in cross-section and arranged that surfaces thereof which are of greater depth in cross-section than the thickness overlap between the laterally adjacent helical turns or strips in each layer to provide an increased area of bonding surface for the adhesive, e.g. the reinforcing members may have bevelled edges, or may be tapered or wedgeform. Bonding may be further improved by having stepped or cranked-form ribbons to provide mutually overlapping portions, or by using ribbons having a series of shallow ribs, grooves, or corrugations. The ribbons or tapes may be preformed from a plurality of cords or strands of synthetic plastic material, e.g. nylon, laid together and adhesively bonded in side-byside relationship. The ribbon members may be continuous in each layer, being wound helically, and the direction or sense of the bias angle of the helical turns is preferably substantially equal and opposite in alternate layers. Alternate layers of the ribbons &c. may be separated by layers of mesh fabric or layers of cords in which strands may extend longitudinally in the direction of the belt. The base layer may be leather, natural or synthetic rubber, synthetic plastic, or textile fabric. The adhesive may be nylon contained in an appropriate solvent.

Title: Improvements in stiffener moulding machines
IPC: A43D8/00
Filed: 1955-11-17
Abstract: 811,323. Moulding shoe stiffeners. CHAPMAN, A. J., and COTTINGHAM, B. R. Feb. 8, 1957 [Nov. 17, 1955], No. 32953/55. Class 17(1) In a machine for moulding counter stiffeners for footwear, comprising a rockable male member 4, against which the blank 19 is pressed by co-operating jaws, and a vertically reciprocable wiper plate 5 which turns over the margins of the blank to form the stiffener flange, the operation of the jaws and wiper being effected by a main drive, in the latter case via a treadle-operated clutch and a rod 9 articulated eccentrically to a wheel 11, the blank is gripped in a pivotally mounted carrier 20 which swings from the loading position to a position 20<SP>1</SP> in which it transfers and releases the blank into the clearance between the jaws and member 4, the carrier being locked against the mould, in response to movement of the carrier to the blank inserting position, by engagement therewith of a pivoted latching member 39, and released by means of a starter member 47 which is moved by an abutment 50, 51 carried by the rod 9. Carrier 20 which pivots about spindle 22 has two pairs of jaws each comprising a fixed but adjustable jaw 24 and a slidable jaw 28 normally held in the clamping position by spring 31. The jaws are opened at the loading and blank inserting positions by abutment on the machine which engage and rotate on arm 33 linked to jaws 28. The carrier is latched in its vertical blank inserting position by engagement of the pivoted spring biased latch member 39 with the nose 40 of a catch arm 37 secured to spindle 22, but is unlocked, before the wiping operation, when a roller 50 attached to rod 9 acts via 48, 46 and 47 to release member 39. An adjustable stud 52 engaging a nib 53 on arm 37 then returns the carrier to loading position. As shown the carrier is moved to the blank inserting position manually by operation of lever 57 which acts via 59, 60, 61, but alternative or additional means, e.g. pneumatic, may be provided. This movement of lever 57 also acts via striker 62, pivoted lever 63, and rod 65 to pivot the notched bell-crank 66 away from its normal locking engagement with arm 69, and so release treadle 18 for operation. Depression of treadle 18 acts via 69 and 72 to swing lever 73, a roller 77 thereon being moved out of a recess 82 in a driven disc 78, and movement of lever 73 operates the clutch. Roller 77 then runs on the surface of disc 78 until it again moves into recess 82, and the movement of lever 73 with this movement of the roller disengages the clutch. A second recess may be provided in disc 78 and be filled or exposed as desired, thus the clutch may be of the one revolution or of the one-half revolution types. The treadle is returned by a cam 88 acting via a rocker arm 86 and cable 87.

Title: Improvements in and relating to rocket propulsion
Inventor: MAHER LOUIS EDWARD
IPC: F02K9/62
Filed: 1954-11-15
Abstract: 802,428. Rocket propulsion motors. ENGLISH ELECTRIC CO., Ltd. Nov. 11, 1955 [Nov. 15, 1954], No. 33075/54. Class 110 (3). [Also in Group XII] In a rocket propulsion motor, combustion takes place in at least two stages including a pre-combustion stage and a further combustion stage, the products from the pre-combustion stage having a lower temperature than the products of the further combustion stage, the rocket motor being so arranged that at least part of the products of the pre-combustion stage is utilized to protect the motor from the high temperature of the products of the further combustion stage. The rocket motor in Fig. 1 comprises a pre-combustion chamber 10, a main combustion chamber 11 and a propulsion nozzle 13, all contained within a cylindrical casing 12. Fuel and oxidant are supplied through the nozzles 15 and it is arranged that there is either an excess of fuel or an excess of oxidant so that the temperature of the products of combustion is less than it would have been with no excess of fuel or oxidant. The products from the chamber 10 pass through a flame stabilizer 16 and either fuel or oxidant as may be required is supplied through nozzles 17-if the products from the chamber 10 contain excess fuel then oxidant is supplied through the nozzles 17, but if the products contain excess oxidant, then fuel is supplied through the nozzles 17. The further combustion in the chamber 11 results in a much higher temperature than that in the chamber 10 and some of the products from the pre-combustion chamber are therefore directed around the flame stabilizer 16 into a space between the wall 12 and the baffles 18 so that a layer of relatively cool gas is interposed between the hot products of combustion in the chamber 11 and the wall 12. Some of the relatively cool gas passes between the baffles 18 so that the baffles are also protected against the hot combustion products. In Fig. 2 the pre-combustion chamber 21 is of annular form and is disposed around the propulsion nozzle 24, the relatively cool products of combustion from the chamber 21 flowing in a rearward direction along the inner surface of the main combustion chamber 23 thereby protecting the wall from the hot gases. Fuel or oxidant as may be required is injected through the nozzle 22 into the main chamber, the gases flowing through the propulsion nozzle 24. Some of the products from the pre-combustion chamber 21 may flow to a baffle system 25 thereby giving additional protection to the convergent wall of the nozzle. The nozzle may be cooled by alternative means such as a lining of-refractory material such as ceramic, a regenerative system of cooling or a liquid film method of cooling. Reference has been directed by. the Comptroller to Specification 738,219.

A fluid-pressure responsive electric switch comprises a resilient diaphragm 10 which, with increase of pressure, moves a switch actuator 22 upwards against an adjustable biasing spring 42 until a flange 48 on the actuator 22 engages a plate 50 on a ledge 55, an adjustable biasing spring 54 pressing the plate 50 downwards, and then the pressure moving the diaphragm 10 and actuator 22 has to be sufficient to overcome the biasing force of both springs 42, 54, before the switch blade 32 is allowed to snap over-centre between contacts 64, 36. An adjusting nut 46 sets spring 42, while a rotatable cam 60 sets the compressive force of spring 54. Manual resetting of the switch is possible by rotating cam 60 until a surface 73 of the spring retainer 56 engages a surface 74 of the actuator 22 to directly drive from the actuator, the cam being retractively rotatable from this position.
