Title: An improved feed for draw benches
IPC: B21C1/32
Filed: 1951-07-02
Abstract: 699,314. Draw benches. BRITISH TUBE MILLS (AUSTRALIA) PROPRIETARY, Ltd. July 2, 1951 [July 6, 1950], No. 15696/51. Class 83 (iv). Draw bench feed mechanism comprises at least two guide tubes carrying mandrel rods, frames near the forward and rear ends of the guide tubes, a pair of carriages in each frame, the carriage of each pair being disposed in different horizontal planes, means whereby both front and rear carriages cross over synchronously, means on the carriages supporting the guide tubes, and means on at least one carriage in the forward frame to cause one guide tube supporting means to move out of the path of the other supporting means during the cross over. The rear end frame 12 slidably supports carriages 9, 10 connected by chassis 45, 46 passing over driving sprockets 47. The carriages support frames 53 in which are mounted pneumatic cylinders 51 whose piston rods 52 are connected to anchor blocks 7 supporting the ends of the guide tubes 8 and mandrel rods 6. Movement of the piston rods will therefore cause axial movement of the guide tubes and mandrel rods. Each mandrel is exactly positioned by means of a worm wheel 59, chain driven from a motor 56 and engaging with a toothed nut 60 operating on a threaded portion of the respective cylinder 51 to effect fine axial movement thereof and hence of the mandrel rod. The forward end frame 18 supports on tracks 17 carriages 15, 16, chain driven from a sprocket 22. The guide tube supports on the carriage 15 are mounted on vertically movable stems 27 and during cross over of the carriages, a wheel 32 rides on a ramp 40 on the other carriage 16, lifting the supports on the stems 27 and preventing the associated guide tubes from fouling the other set. The drive for the changeover is derived from a motor 70, through a hydraulic pump and a pair of cylinders 74, 75 connected to the ends of a chain passing around a sprocket on shafts 71, 72. Switches 62 on the frames 53, in conjunction with plungers 63 on the guide tubes ensure that the motor 70 can only operate to effect cross over of the carriages when the guide tubes and mandrel rods are fully retracted. The forward ends of the guide tubes 8 are spring loaded and telescopic. Bracing members 90 add rigidity to the guide tubes.

Abstract: 345,881. Thermal switches. AKTIEBOLAGET BIRKA REGULATOR, 48, Surbrunnsgatan, Stockholm. May 22, 1930, No. 15816. Convention date, May 25, 1929. [Class 38 (v).] In an arrangement in which an electric heater 1 causes, when a predetermined temperature is reached, a thermal switch 8 in thermal association with it to close a circuit to the heating winding of a main thermal switch 2, the switch 2 then opening its contacts to break the main circuit to the heater 1, the heating winding of the switch 2 is made in two or more parts the number of which included in circuit is varied by an auxiliary thermal switch 11. As shown, the winding consists of a thicker portion 6 and a finer portion 7 the latter being normally short-circuited by the thermal switch 11. The thermal switch 2 consists of two rods 4 contacting at the centre and connected at their outer ends to a frame 5 that expands under the action of heat. When the switch 8 closes its contacts, a maximum heating current flows through the portion 6 of the winding so that the switch 2 soon opens its contacts. The switch 11 then opens under the influence of the winding 6 thereby inserting the winding 7 in series with the winding 6 and diminishing the heating effect. The heat is however sufficient to maintain the switches 2, 11 open until the heater 1 has cooled and the switch 8 opened again.

[Also in Group XL (c)] An oscillator is synchronized with a train of sync. pulses by the use of a phase-comparing valve, of which the anode is fed from the oscillator, and the grid by the sync. pulses through an aperiodic damped oscillatory circuit. The sync. pulses (a), Fig. 2, are applied to the grid of an auxiliary valve 5 whose anode circuit includes a parallel combination of inductance L, capacity C, and resistance R. These parameters are such that the anode voltage assumes the form (b), the sharp pulse formed by the leading edge of each sync. pulse being completed before the trailing edge becomes effective. The sharp pulses b are applied to the grid of the phase-comparing valve 1 to the anode of which pulses (c) derived from the oscillator 7 are applied through a capacity 6. When the system is used for synchronizing the scanning of a television receiver, the pulses (c) are derived from a transformer feeding the scanning coils, and a delay network 8, 9 may be interposed. At synchronism, the positive tips of the pulses (b) occur at the centre of the rising slope of the pulses (c). When deviation occurs, the anode output voltage of the valve 1 rises or falls, and this output is fed through a smoothing network 11, 12 and potential divider 14, 10 to adjust the frequency of the oscillator in corrective sense. The shunt element 12 of the network comprises a condenser in parallel with a series arrangement of capacity and resistance.
