Filed: 1919-09-18
Abstract: 142,733. Fall, T. A. Sept. 18, 1919. Clutches, friction; operating clutches. - In clutches for use on motor-vehicles &c., radially movable clutch segments which may have inner cam surfaces are actuated by trains of wedges carried in pockets in the clutch member carrying the segments, radial movement of one wedge being produced by displacement of another. The floating clutch segments 11<a> are separated bv springs 16 and have eccentric inner surfaces, and are pressed outwards into contact with the axially curved surface of a drum 1 by wedges 10, which may be of differing lengths so as to bring the segments successively into action and are operated by axially sliding wedges 9 and radially sliding wedges 8 actuated by the clutch collar 11. The wedges 8, 9, 10 are all carried in slots in the inner clutch member 5 keyed to the shaft 4. The clutch segments may be formed in two parts 11<b>, 11<c> separated by springs 16<a>. Springs 15 bearing on lugs 13 on arms, 6 on the member 5 return the wedges 10 for disengagement. The wedges 9 may each be formed with a central depression instead of a projection, in which construction the wedges 8, 10 are pressed in opposite radial directions by a common spring. The collar 11 is operated by toggle links 18, 19 controlled by a rocking lever 20 which is itself controlled, by a hand-lever 24 and adjustable link 23 so as to move over its dead centre during clutch engagement and so prevent return except by movement of the link 19.

Title: Improvements in or relating to thread tension control devices for sewing machines
IPC: D05B47/00
Filed: 1955-08-16
Abstract: 804,439. Sewing machines. PFAFF, A. G., G. M. Aug. 16, 1955 [Aug. 16, 1954], No, 23529/55. Class 112 Thread controlling. The thread tension in a sewing machine is released when the presser bar is raised by either a handoperated lever 30 or by a lever 29 operable by a treadle or knee-press A cam 33, carried by lever 30, depresses one arm 83 of a lever pivoted at 82 when lever 30 is operated. The hooked end 87 of a bar 86 depend ing from lever 29 raises the other arm 84 when lever 29 is operated. Operation of either one of levers 29 or 30 thereby causes a plate 85, carried by arm 84, to raise a plunger 70 against the action of a spring- biased pin 77. An inclined part 75 at the head of a plunger 70 then imparts movement to a slidable rod 68, and the latter co-operates with a lever 64 and pivoted plate 61 to move a pin 63 for separating the discs of a thread-tensioning device 54. Work-feeding, presser bar lifting. A needle bar 14 and a presser bar 18, which carries a feeding presser foot 19 adapted to co-operate with feed dog, are mounted in an oscillating bracket 15. The main presser bar 20, carrying a presser foot 21 is biased downwardly by a spring 22 and also carries a bracket 23 to which is pivoted a bellcrank lever 35. One arm of the latter is connected by a link (not shown) to presser bar 18, and the other arm is connected by a link 37 to a crank 38 carried by a shaft 39, oscillation of which thereby causes alternate lifting of bars 18 and 20. When lever 30 is operated, cam 33 co-operates with a cam 23a on bracket 23 to raise the presser bars. Lever 29, when operated, co-operates with a pin 28, carried by a bar 27 secured by a screw 26 to bracket 23, to raise the presser bars.

Title: Web tension control
Inventor: VISCHULIS GEORGE
IPC: B65H23/08
Filed: 1959-07-09
Abstract: 918,072. Band brakes. MIEHLE-GOSSDEXTER Inc. July 9, 1959, No. 23634/59. Class 103 (1). [Also in Group XVI] A web tension-controlling roller 30 is carried by arms 31 pivotally mounted on a shaft 32. Torque on the shaft 32, exerted by the weight of the roller 30 when displaced from the position shown is compensated for by a spring 75 which presses a cam 72 into engagement with a camfollower 74 on an arm 50 fixed to the shaft 32. The cam 72 has pivots 82, 83 spaced equidistantly from the centre of the cam 72 when in the position shown in Fig. 1. Movement of the roller 30, due to an increase in web tension, causes the cam 72 to rock about the pivot 82 to assume the position shown in Fig. 3. The spring 75 exerts clockwise torque on the shaft 32 to compensate for the counter-clockwise torque exerted by the weight of the roller 30 in the position displaced from neutral position shown in Fig. 1. Similarly, the cam 72 pivots about the pivot 83 on a decrease in tension to attain the Fig. 3 position in which the spring 75 exerts counter-clockwise torque on the shaft 32. Variations in web tension cause the arm 50 to actuate a fluid pressure control 45 connected to fluid pressure actuators 28 which tension web roll engaging straps 24 to control braking force exerted on the roll 20. A manually, adjustable regulator R supplying a loading cylinder determines the tension to be maintained in the web. A dashpot 54 damps movements of the roller 30. Specification 918,071 is referred to.

Title: Improvements in coiled tubes suitable for heat-exchangers
IPC: F28D7/02
Filed: 1938-08-11
Abstract: 517,937. Heat-exchangers; ice-cream freezers. WHITAKER, A., BARNES, N., and JESSEL, R. Aug. 11, 1938, Nos. 23676 and 25984. [Classes 29 and 64 (iii)] A heat exchanger of the multi-layer coil type is formed by winding a coil with a first turn 1 of large diameter, then two turns 2 of smaller diameter, then two turns of larger diameter, and so on. The coil is then axially compressed so that the turns 2 lie within the turns 1. Metal straps may be permanently brazed to the turns of the coil to hold it in position, and may be extended to form fixing means for the coil. Coils of three or four layers may be similarly formed. As applied to an ice-cream freezer, Fig, 3, a container 7 is'mounted on a rotating spindle 8 and surrounded by a heat exchange coil 9 through which refrigerant is passed. The coil 9 is held by straps 3 secured to the bottom wall 10 of the tank. A cylindrical baffle 11 is arranged between the coil 9 and the wall 6 of the brine tank, which, with the construction of the heatexchange coil, ensures improved convection circulation of the brine by separation of the upward and downward streams.

Title: Improvements in or relating to gaseous electric discharge tubes
IPC: H01J17/48
Filed: 1951-10-11
Abstract: 720,179. Multi-gap cold-cathode tubes. INTERNATIONAL BUSINESS MACHINES CORPORATION. Oct. 11, 1951 [Oct. 26, 1950]. No. 23688/51. Class 39 (1). [Also in Group XIX]. In a gaseous discharge tube of the glow transfer type, the position of the glow discharge on a given electrode, which may be an anode or a cathode, is determined solely by the surface materials of that electrode. Thus, if a number of plane cathodes each having one part made of nickel and another part made of carbon are arranged opposite a common anode, a discharge between any cathode and the anode will concentrate at the nickel part of the cathode since this part has the lower work function. In the tube shown the cathodes are in the form of hollow cylinders coated on the inside with nickel and on the outside with carbon so that the glow discharge is confined to the inside of each cathode. Ten storage position cathodes CP-0 to CP-9 and ten glow transfer cathodes CO-0 to CO-9 are separated by insulating plates I and arranged in a circle equi-distant from a common ring anode A which is formed in two sections to prevent overheating when processing and may be arranged in line with the longitudinal axes of the cathodes or offset therefrom. Glow transfer wires TP-0 to TP-9 and TO-0 to TO-9 are each attached to a cathode and extend either around the edge of an insulating plate I or through a perforation in the plate to the region of intense ionization adjacent the open end of a neighbouring cathode, to determine the direction of transfer of the glow discharge along the array of cathodes. The tube is connected in a circuit (see Group XIX) whereby starting cathode CP-0 is connected individually and storage cathodes CP-1 to CP-9 are connected in common to a source of positive voltage while transfer cathodes CO-0 to CO-9 are connected in common to the anode of a triode tube which is biased to cut-off so that when positive pulses are applied to the grid of this tube the voltage applied to the transfer cathodes is varied alternately above and below that applied to the storage cathodes and the glow discharge is stepped along the array of cathodes to the storage cathode corresponding in number to the number of pulses applied to the grid of the valve. The tenth pulse returns the glow discharge to the starting cathode CP-0 and an output is obtained. Alternatively, by providing an individual connection to each position cathode CP-1 to CP-9 an output can be obtained for each pulse applied to the tube. Specifications 708,114 and 708,119 are referred to.
