Abstract: 578,359. Handle-bars. BIRMINGHAM SMALL ARMS CO., Ltd., and MACCABE, D. A. Nov. 24, 1944, No. 23408. [Class 136 (iii)] A handle-bar for a cycle comprises two tubular members 15 having outer ends, of any desired shape, substantially perpendicular to depending portions which fit into longitudinal slots in a clip member 1 secured to the top of the usual steering stem 3, the slots being open at one end and complementary in shape to the tubular members which are secured in position by a split clamp 7 fitted over the clip and associated with friction clamping means. The clip 1 has a circular base so that it may be fitted into the tubular part of the steering stem 3, where it is secured by brazing. Two diametrically opposed longitudinal slots are formed in this upper portion, open at their upper ends and of arcuate cross-section so as to form in conjunction with the split clamp 7, vertical recesses to receive.the tubular members 15. A dust-excluding cover 9 is fitted over the upper surface of the clamp. The vertical depending portions of the handle-bar are of smaller diameter than the end portions and are arranged to pass through circular holes in the dust-excluding cover into the recesses and, after being adjusted to the desired angle, are secured therein by tightening the bolt 17 in the split clamp.

Title: Improvements in plate or sheet shearing machines
IPC: B23D15/14
Filed: 1954-08-13
Abstract: 761,502. Shearing. SCHLOEMANN AKT.- GES. Aug. 13, 1954 [Sept. 30, 1953], No. 23546/54. Class 83 (4). The inclination of the movable blade of a guillotine is automatically variable in accordance with the thickness of the work. One end of the movable blade 12 is mounted on a pivot 11 carried by a beam 7 slidable vertically in the main frame 1 and the other end is connected to a piston 13 in a cylinder 14 rotatably mounted on the beam 7. When the holddown 3 carrying work-engaging studs 6 is moved down to engage the work 2 by hydraulic cylinders 4, 5, a stop on the hold-down 3 rotates a lever 21 against the action of a spring by an amount dependent on the thickness of the work 2. Disengagement of the lever 21 from a control switch 22 on the movable blade 12 opens a valve 26 to cause piston 13 to lessen the inclination of the movable blade until the lever 21 operates the switch 22 to close the valve 26. The cutting stroke is effected by the hydraulic cylinders 10 and the beam 7 and blade 12 move together until stopped by operation of a switch 25 by a projection 12b on the blade 12. The hold-down 3 near the end of its upward movement actuates a switch 23 which results in the raising of piston 13, whereupon the movable blade actuates a switch 24 to cause the beam 7 to be lifted to it initial position.

Abstract: 849,495. Tunnel kilns. GIBBONS BROS. Ltd. July 31, 1957 [Aug. 1, 1956], No. 23689/56. Class 51 (2). The cooling section of a tunnel kiln for firing ceramics comprises three successive indirectly cooled zones, namely, a rapid cooling zone immediately beyond the firing zone having air chambers 10 and 11 in the side walls and roof respectively, a slower cooling zone with air chambers 28 in the roof, and a final cooling zone with air chambers 31 and 32 in the side wall and roof respectively. The rapid cooling zone has damper-controlled side inlets and roof outlets 13 respectively, and in this zone the tunnel atmosphere is recirculated to give controlled cooling. Longitudinal flues 15 are disposed in the side walls at about the level of the kiln car floors communicating with the tunnel interior by ports 16 and with a fan 19 which recirculates the kiln atmosphere through a duct 17, branch pipes 18 having dampers 22, and forwardly directed nozzles 20. A heater 23 or an air port 24 provided in the recirculation system enable the gases to be kept at about 600‹ C. The recirculation system may extend partially into the next cooling zone in which the roof cooling chamber 28 has an inlet 29 and damper-controlled outlet 30 connected to the main fan. Auxiliary burners 27 in the side walls may be used to maintain the temperature of the lower parts of the kiln cars. The final cooling chambers 31, 32 have inlets 33 and 35 and damper-controlled outlets 36 and 34 respectively connected to the main fan, the zone being divided into separate sections longitudinally and vertically.

Title: Remote control systems for electric motors
IPC: G05D3/12
Filed: 1957-07-29
Abstract: 810,649. Control of motors. COLLINS RADIO CO. July 29, 1957 [Sept. 13, 1956], No. 24000/57. Class 38 (3). In a remote control system for an electric motor 76, a motor-driven shaft 79 is actuated to a position in accordance with the selected adjustment of a control knob 40 which is coupled to the rotors 26, 36 of a control switch 20 and an earthing switch 30, respectively. The adjustment of the control knob to its fourth position, for example, aligns switch-notch 27 with stator contact 24, and engages stator contact 23 with rotor 26. This establishes a circuit from power source 29 to energize the motor through contact 57 whereby the motor starts to drive the output shaft 79 and to rotate the switch-rotors 56, 66. When the contacts 53, 57 are disengaged, the motor circuit is maintained through contacts 63, 67 so that resistor 73 reduces the motor speed. After further rotation of the shaft 79, contact 67 engages both contacts 63, 64 the latter being earthed through resistor 74 and contact 34, whereby the motor is shunted by the resistor for further reduction of speed. Shortly thereafter, contacts 63, 67 disengage and the motor is disconnected from the power source. As the motor continues to rotate under its momentum, contact 57 engages stator contact 54 and both sides of the motor are earthed to obtain a quick stop. Specification 660,939 is referred to.
