Title: Improvements in or relating to adjustable cams
IPC: C03B9/40
Filed: 1938-04-26
Abstract: 503,657. Making hollow glassware. UNITED GLASS BOTTLE MANUFACTURERS, Ltd., and DORMAN, E. P. April 26, 1938, No. 12461. [Class 56] [Also in Group XXIV] Relates to an adjustable cam particularly intended for controlling the incidence and duration of the blowing period in a rotary machine for making hollow glassware. According to the invention, the cam comprises a pair of angularly displaceable control members 20, 21, adapted on being moved apart to deflect outwardly a flexible member 9 made up of a plurality of pivotally interconnected sections so that a part of the flexible member forms a continuation of the cam surface, and means such as displaceable or depressible latches or pins 30, operable by and upon displacement of a control member to permit inward or outward movement of a part of the flexible member. The control members 20, 21 are guided by a channel 24 on the glass-blowing machine and the flexible member 9 has one end fixed in the channel whilst the other end is attached to a tension spring 16. Handles 47, 49 enable the positions of the members 20, 21 to be adjusted whilst the machine is running. The pivot pins 10 of the portions of the flexible member directly under a control member are guided by a groove 22 in the control member and the remainder of the flexible member is held in place by the spring-pressed pins 30 which engage inside the flexible member between the members 20, 21 and outside the flexible member beyond the members 20, 21. The pins 30 beneath the members 20, 21 are depressed by cam surfaces 35 to allow the flexible member to be deflected.

Title: Improvements in and relating to buttonhole sewing machines
IPC: D05B3/06
Filed: 1924-05-21
Abstract: 224,469. Imrie, H., (Reece Button Hole Machine Co.). May 21, 1924. Button-hole sewing-machines of the kind in which the stitch-forming mechanism is rotated at one end of the button-hole to form an eye, are provided with means for interrupting the stitching at will during the rotation so as to produce a straight button-hole. In the construction shown, a frame 5 supporting the stitch-forming means is moved to and fro on the bed-plate. The stitching devices are rotated about a vertical axis by a shaft 7. The driving shaft 10 for the stitching device is driven by a pulley 11 clutched thereto by a clutch of known type comprising a spring dog 12 pivoted at 98 to a hub 99 fast on the shaft and engaging a cam 13 on the pulley 11. The clutch is disengaged by a head 17 carried by a rocking member 19 held in inoperative position during stitching by a latch 22 engaging a projection 23. At the conclusion of a cycle a screw 28 carried by the latch 22 engages a fixed stop and releases the rocking member 21 to stop the shaft 10. In order to stop the shaft when desired while the mechanism is rotating about the end of a button-hole, the latch 22 is provided with a tail 29 adapted to engage an abutment 30 as the frame 5 reaches the end of its traverse. After the stitch-forming devices have made their half-rotation, the shaft 10 is again clutched to the driving pulley by the operation of means comprising a latch 33 which snaps over the end of the arm 21 of the rocking member 19 and, as the frame is retracted, turns the rocking member into a position to be re-engaged by the latch 22. In order to provide for the sewing of an ordinary eyelet-ended button-hole when desired, the abutment 30 is mounted on a pivoted arm 33 which may be swung aside by movement of a fingerpiece 39.

Title: Improvements in and relating to distress rockets
Inventor: LITTLE DAVID ANTONY SINCLAIR
IPC: F42C7/12
Filed: 1963-03-29
Abstract: 996,872. Signal rockets. JAMES PAIN & SONS Ltd. March 29, 1963, No. 12631/63. Heading F3A. A hand-fired rocket assembly includes a percussion device of which the spring-stressed percussion pin 5 extends through a hole 4 in the base 2 of the firing tube 1 and is held by a trigger mechanism comprising a slide 6 and a member 9 pivoting on the slide. The slide has arms 7 extending on opposite sides of the shank of the pin 5 and an arched portion 8 coupling with projections 12 on the legs 11 of the member 9, the body portion 10 being semicircular. In the storage position the member 9 is flush with the slide, and the portion 10 abutting the pin 5 prevents withdrawal of the slide. In the firing position, Fig. 2, the member 9 pivots under gravity through an angle less than 90 degrees, the face end of the legs 11 moving in an annular groove 13 in the base 2; a force causing the member to pivot further results in withdrawal of the slide thus releasing the pin. In a modification the slide is pivotally attached to the base of the tube so that when the member 9 is forced past its equilibrium position the slide pivots about an axis perpendicular to the base to release the pin.

Title: Improvements in Resistor Elements
Inventor: OGLE EDWARD JOHN
IPC: H01C17/02
Filed: 1967-03-17
Abstract: 1,186,551. Resistor manufacture. POWER DEVELOPMENT Ltd. 14 June, 1968 [17 March, 1967], No. 12684/67 Headings H1K and H1S. A -resistor body is coated for protection and insulation with powdered material by dipping into a fluidized bed of the material. A cylindrical resistor block, which may have non-linear characteristics, to be coated is produced by firing a powder, extruded paste or a cast slip mass. The flat end faces are then metallized, leaving a peripheral annular zone free from metal to provide contacts, prior to dipping. If the coating is of a synthetic resin, for example, an epoxy resin, the resistor block is heated prior to dipping sufficiently to fuse the powder on to the block in the fluidized bed. Additional heating to a higher temperature after removal from the fluidized bed ensures a fully cured, coherent coating. If the coating is a refractory metal oxide such as alumina or a mixture of such oxides, adherence of the powder in the fluidized bed to the resistor block is achieved by prior coating of the block with an adhesive slurry containing ethanol, water, ethyl silicate, hydrochloric acid and zirconia. Subsequent heat treatment in a suitable atmosphere then hardens the coating. The coating process may be repeated to obtain adequate layer thickness. The metallized end portions do not receive any coating. Specification 764,693 is referred to.

Title: Improvements in or relating to revolving clearers for use in textile combing machines
IPC: D01G19/22
Filed: 1942-09-09
Abstract: 559,125. Combing machines; ratchet gearing. PLATT BROS., & CO., Ltd., and PIERREPONT, D. Sept. 9, 1942, No. 12720. [Class 120 (i)] [Also in Group XXIV] In a revolving clearer for textile combing machines the clearer roller is rotatably mounted in a pair of co-axially pivoted bearer arms and loaded by frictional means on at least one of the arms so as to oppose rotary movement of the roller in one direction ; the frictional means may comprise a dog or wedge which may be spring-influenced. As shown the clearer roller 10 is mounted in arms 16 each comprising two parts 12, 13 pivoted and secured together by screws 14 and the part 12 carrying a pin 33 pivotally mounted in a slot 31 of a plate 30 secured to the pin 24 on which the weighting lever 23 of the detaching roller 18 is mounted : the axle 34 of the clearer rollers projects through one of the parts 13 and may carry a cylindrical roller or bowl 35 the axle or bowl being yieldingly engaged by the cam surface 39 of a dog 38 which is fulcrummed on a stud 36 in the part 13 and is engaged by a light-plate spring 40. In the working of the machine the lever 23 is rocked about the pivot 27 to move the detaching roller and the clearer, by reason of the pin 33 engaging an axtension 32<SP>1</SP> of the slot 31 is also reciprocated to and fro, its movement in the forward direction causing it to be driven by the roller 18 while the bowl 35 rotates freely against the dog 38 ; in the backward movement the clearer roller begins to rotate in the opposite direction but rocks the dog on its stud 36 so that it wedges against the bowl 35 and stops the reverse rotation of the clearer roller. Extensions 17 on the arms 13 facilitate the raising of the clearer roller for cleaning purposes, the roller being first drawn back in the slot 31 until the pin 33 engages in the slot extension 32<SP>1</SP> when the clearer may be tilted about the pin 33 ; extensions 16 at the forward ends of the arms 13 ensure that the roller shall not fall too far between the top detaching rollers when they are in their most widely separated positions, the extensions then resting on the arbor of the roller 18. The dog may be located in a recess in the arm 13 and covered by a plate to exclude dust and may be wedge-shaped to engage a V-grooved drum on the axle of the clearer roller. The pivoted dog may be replaced by a steel ball or roller or a wedge-shaped plunger located in a cavity in the arm and pressed by an adjustable spring into engagement with the axle of the clearer roller or a bowl thereon.

Title: Improvements in manufacture of rubber hydrohalide film
Filed: 1938-05-03
Abstract: 501,239. Rubber hydrohalide films. MACK, G. C. May 3, 1938, No. 13135. [Class 70] A thin film of rubber hydrohalide is made by casting a solution of rubber hydrochloride or hydrobromide on a continuous surface, evaporating a part of the solvent to obtain a self-supporting film, stripping the film from the surface, stretching it longitudinally, or laterally, or both, and removing the remainder of the solvent. As shown, a solution of rubber hydrohalide, e.g. in benzene or chloroform, is applied from a tank 3 to an endless belt 4 on which it is spread by a knife 5. The belt passes through a drying chamber 1 where the solvent content of the film is reduced to about 10-20 per cent, and the film is stripped and passed between two pairs of driven rollers 11, 12. The peripheral speed of the first set of rollers is the same as that of the belt, and the speed of the second pair at least twice as great so that the film is stretched 100 per cent or more. The stretched film is then festooned over rollers 13 in a second chamber and dried. It finally passes out through driven rollers 14 to a wind-up roll 15. U.S.A. Specification 2,078,526 is referred to.
