Title: Improvements in machine gun locks
IPC: F41A9/33
Filed: 1945-10-29
Abstract: 603,750. Machine guns. VICKERS-ARMSTRONGS, Ltd., and HIGSON, P. R. Oct. 29, 1945, No. 28637. [Class 92 (ii)] A machine gun of the Vickers type, in which the firing-pin 5 is operated during the locking action of a side lever 10 actuating a reciprocating breechblock, has the firing-pin displaceable to the firing position in and relatively to the breech-block, the side lever serving to drive it forwardly relatively to the breech-block to fire the gun upon the closing of the breech. In the construction shown, the firing pin 5 has a slot 14 through which passes the pin 13 to which the side lever 10 is pivoted. The firing-pin is urged rearwardly by a spring 7, but when the lever 10 urges the breechblock to the closed position a surface 12 on the lever engages with a surface 11 on the firing- pin and pushes the latter forwardly to fire a shot. On the breech-block is a guide 17 for the rim of a fresh cartridge and the round is urged downwardly by a carrier 15, which slides in channels in the guides and which is moved by engagement with surfaces on either side of a fixed cam 19, 20. The cartridges are thus brought successively into alignment with the cartridge chamber B. On the carrier is slidably mounted a slide 25 carrying a spring- loaded ejector 23 adapted to eject the last round. When the guide is in its forward position to pick up a fresh round Cl, the lower end of the ejector is pushed to the rear against the action of its spring by that round. But when there is no fresh round the lower end is pushed outwards by its spring and, when the slide moves downwards, strikes the case of the last round and, with the help of a detent 4, ejects it. Specification 414,658 is referred to.

Abstract: 1,212,532. Bakery apparatus. BAKER PERKINS Ltd. 20 Sept., 1968 [21 June, 1967], No. 28644/67. Heading A2A. [Also in Division B5] In bakery apparatus, particularly for baking biscuits, a sheet of dough, e.g. biscuit dough from which biscuit blanks are to be cut out, is gauged by passing it between upper and lower gauging rolls 1, 5 of which the roll 1 is journalled on a fixed axis by a shaft 2 and bearings 3, whilst the roll 5 is adjustable towards and away. from the roll 1 by mounting its shaft 6 eccentrically in circular or part-circular bearing blocks 8 which are themselves rotatable through worm gearing 13, 14 by a handwheel 19. It is said that by making the lower roll the adjustable one the measurement of the gap 12 between the rolls given by a clock gauge 20 more accurately represents the working gap since this gap is not increased substantially by taking up of tolerances resulting from the dough tending to force the rolls apart, the tolerances in the lower roll mounting assembly being already taken up by the weight of the roll 5 acting in the take-up direction. The roll 5 is flanged to receive the roll 1.

Title: Improvements relating to weighing balances
IPC: G01G1/00
Filed: 1957-09-11
Abstract: 848,846. Weighing balances. GREEN, R. S. Sept. 10, 1958 [Sept. 11, 1957], No. 28663/57. Class 143 A balance of the two-pan, three knife-edge type has a weighing compartment 4 comprising a clear space within the balance case which space is free of the operating mechanism and indicating system, the said compartment being separated by partition means from the rear of the balance case. The partition 3 comprises a rear lower vertical portion 3a, an upwardly and forwardly inclined central portion 3b, and a front vertical portion, the operating mechanism being situated behind the partition or above or beside the weighing compartment 4. In the form shown the rigid sides of the metal case support a bridge 5 of channel cross-section which carries a post 6 with a plane for the central knife edge, the beam carriage 11 being mounted above and within the bridge and being supported on rods or pillars (not shown) situated close to the sides of the case and vertically displaceable by cams (not shown) on the actuating shaft 18. The carriage may alternatively be supported at the centre on bars carried by the bridge and actuated by a cam shaft located in the space between the bridge and the carriage. The pans 25 are suspended from hooks 21 on bars 22 having planes 23 which rest on the outer knife edges 24 of the beam 42, the suspension means comprising the rods 26, 27, 28 and 40. Pan damping is achieved by the engagement of ball 30 and disc 31 actuated by cam 29 on cam shaft 29: beam damping is effected by movement of discs 33 (not shown), carried by arms 32 extending from the beam ends, within cups 34. A ring or like weight may be added to the load on the weight-carrying pan, the ring 36 then being supported on pins 35 projecting from the bar 22 on the appropriate end of the beam: normally the ring is supported free of the pins 35 by the hook 50. The inclination of the beam is indicated by the projection of an image of a graticule 53 onto a screen 39, theoptical path being from a light source 49, through the graticule and a lens 56 and via mirrors 57 to the screen. The graticule carries two scales, one to be read when the ring weight is applied and the other when it is removed. A shutter 38 in the optical path obscures the irrelevant scale, the movement of lever 47 when cam 45 is rotated by shaft 44 serving both to actuate the ring- changing rod 48 and at the same time to move the shutter 38 to the appropriate position.

Filed: 1969-06-06
Abstract: 1,207,080. Winding webs. SCOTT PAPER CO. 6 June, 1969 [12 June, 1968], No. 28886/69. Heading B8R. [Also in Division F2] Web winding apparatus comprises a bedroll over which a web 41 is fed to a core 43 disposed on one of a plurality of rotatably mounted winding mandrels 44 carried by a rotatable turret past a pick-up position where a free leading edge, formed by severance of the web by a knife 50, is transferred to a core disposed on a successive mandrel, the surface of the bedroll having a plurality of apertures 33 therein, the apertures communicating with stationary suction means effective for holding portions of the web overlying the apertures to the bedroll. The apparatus may include means 75 for applying adhesive to the leading edge of the web, and the arrangement is such that during the gluing, cutting and transferring operations the relative portions of the web are held firmly in contact with the surface of the bedroll. Thus, if the web should break during these operations or during operations such as longitudinal slitting that may take place on the bedroll, or fail to transfer to a core 43, the bedroll will carry it safely past the pick-up position, where it can be received by a web-disposal unit 82. The bedroll comprises a shell (11) supported by trunnions (13, 14, Fig. 1, not shown) for rotation on a fixed shaft (16) carrying plates 25, 26 which define a vacuum chamber 22 communicating through apertures 32 to a passage 30 formed in the shaft 16, to which passage a vacuum pump or suction fan is connected. A further chamber 88 defined by the plate 26 and a plate 90 may also be provided, this chamber communicating by way of apertures 87 and a passage 31 to a source of high-pressure air which deflects an unwound web into the disposal unit 82.

Abstract: 775,033. Hydraulic brakes. ALDASORO, E. Oct. 7, 1954 [Nov. 5, 1953], No. 28918/54. Class 103 (1). [Also in Group XXIX] A safety device for hydraulic pressure installations, e.g. hydraulic brakes, comprises a casing 10 provided with several cylinders 11 having outlet pipes 30 at their lower ends and a top casing cap 12 with an inlet pipe 16 from a main cylinder communicating with the upper ends of the cylinders 11 and with an inner chamber 201 having passages 23 leading to the upper part of each cylinder and a central duct 25 joining lateral ducts 26 leading to the lower part of each cylinder, and with a valve 38 at the join, the pistons moving against springs 43 to cut off the passages 23 from the outlets and operate an electrical optical or acoustic indicating device 34 when they move to the bottom of their cylinders on an outlet pipe being fractured. Normally pressure at 16 is communicated to the brakes connected at 28 by the pistons being forced down in their cylinders, the pistons returning against cap stops 21 when the pressure is released at 16. Should a brake pipe 29 burst the piston makes an electrical contact at 32 when pressure is applied at 16 and this operates an alarm 34. The passages 23 enter the cylinders below the pistons in their raised position and allow expansion of the hydraulic fluid on temperature rise. Leakage of fluid along these passages on breakage of the brake pipe is prevented by the seal 42 on the pistons moving below the passages 23. Air in the hydraulic system may be removed through a valve 38 by means of a screw 36.

Title: Method and apparatus for recommencing spinning of a broken thread in an open-end spinning device
IPC: D01H4/48
Filed: 1972-06-21
Abstract: 1391211 Control of restarting spinning in open-end spinning machines SKF KUGELLAGERFABRIKEN GmbH 21 June 1972 [21 June 1971] 29116/72 Heading DID A method of restarting spinning, when a break occurs, in an open-end spinning machine comprises reversing delivery rollers to feed back spun thread to the spinning rotor to recommence spinning, the delivery rollers being then reversed again to draw off spun thread. The second reversal occurs after a predetermined time lapse which is shorter than the time in which a trimmed end of thread is fed from a cutting device to the spinning rotor to pick up further thread spun in the spinning rotor. The apparatus for performing this method comprises a drive roller 5 which during normal spinning is borne on by and drives a feed roller 4a. On thread breakage as detected by an electronic stop motion 2 a control device 20 through actuators 28 and 19 respectively tilts the spinning head to disengage the rotor, opener and feed roller drives and rocks a lever 16 to disengage feed roller 4a which hence also stops. Brakes 17 and 18 are provided to quickly stop rotation. A cutter 7 severs the thread and the cut off end and excess fibre in the spinning chamber are sucked away by a low pressure source 32. After a delay timed by the control device 20 actuator 19 brings a second delivery roller 4b to bear on drive roller 5 and thus reverse feeds the cut thread end. When the thread end reaches stop motion 2 a signal is generated and the control device 20 restarts the mechanisms of the spinning head and switches on a constantly driven pulse generator 37. After a predetermined number of pulses, by which time the thread end will have entered the spinning rotor, actuator 19 moves lever 16 to re-engage the forward delivery roller 4a and hence restart normal spinning. A thread reserve lever 11 takes up excess thread due to momentary slipping of the thread package 21 on reversal.

Abstract: 687,806. Treating gases with liquids. BRITISH INSULATED CALLENDER'S CABLES, Ltd. Nov. 29 1951 [Nov. 30, 1950], No. 29389/50. Class 55 (ii). An apparatus for treating gases with liquids, for example, for the recovery of vaporised solvents such as cresylic acid from air coming off from a wire enamelling oven, consists of a vertical pipe having upper and lower sections 1 and 3 separated by a flanged pipe 2 within which is mounted a jet tube 4 connected to the pipe 1 by a cone 5 and a horizontal plate 6. Above the jet tube is mounted an injector tube 8 which extends up inside the pipe 3. In operation, gas is blown up through the pipe 1 and tube 4 into the tube 8, the injector action inducing a recirculating gas flow down the outside of the tube 8 and into the tube again. Liquid for example, water, is supplied into a chamber 13 and flows through a pipe 12 into a chamber 11 whence it passes through a ring of holes 10 to be entrained by the upflowing gas stream. The liquid returning with the recirculating gas collects on plate 6 until it reaches a level determined by an adjustable weir 17, part flowing over the weir and the remainder passing through holes 7 back into the gas stream. Two of the above units may be arranged one above the other, the liquid passing either in parallel or jn series through them. Fig. 5 shows the lowermost of two units through which liquid flows in parallel, a pipe 32 conveying fresh liquid to the unit shown, the overflow uniting with spent liquid descending from the upper unit through a pipe 39 and discharging into a sump, whence it is conveyed, by a pipe 41 to a settling tank.
