Title: Device for preventing the over-heating of the oven-grill in an electric cooker
IPC: F24C7/08
Filed: 1937-04-06
Abstract: 475,470. Locking switches. CHALLET, E. April 6, 1937, No. 9749. Convention date, April 6, 1936. [Class 38 (v)] The switch controlling the top heater of an oven is interlocked with the switch controlling the bottom heater by means of cams a, c on the two switch spindles and a sliding rod f arranged between. The arrangement is such that when the pointer b of the top switch is moved into the full on position G, the cam a touches the top of the rod f and prevents any movement of the lower switch from its " off " position. Movement of the lower switch into any of its three " on " positions will also raise the rod f and prevent the top switch being moved " full on." The top switch may, however, be moved into positions 1 and 2 in which it is “ and ¢ on respectively. In a modification, Figs. 5-8 (not shown), the cam a has a wider portion corresponding to the " ¢ on " and " full on " positions, so that when the lower switch is moved into any of its " on " positions the upper switch can only be " off " or " “ on."

Title: Improvements relating to braking devices for the warp beams of looms
IPC: D03D49/08
Filed: 1954-04-03
Abstract: 822,601. Brakes for warp beams. JUTE INDUSTRIES Ltd., and PLENDERLEATH, J. S. Jan. 2, 1956 [April 3, 1954], No. 9844/54. Class 142(2) A warp beam brake comprises two adjustable spring devices, the second automatically reducing the braking force as the warp is drawn from the beam. In one embodiment (Fig. 1), a warp beam 1 mounted at each end on rollers 3 has drums 2 each braked by a band 6. One end of the band is connected to a rod 7 which is influenced by a spring 11 the force of which is adjusted by a handwheel 15. The other end of the band is connected at 17 to a lever 20 pivoted intermediate its ends. The lever 20 is conected by an adjustable spring device 22, 30, 32, 33 to a lever 25 and an arm 28 carrying a roller 29 that presses on the yarn 5. As the diameter of the yarn 5 decreases, the arm 28 and the lever 25 pivot anticlockwise (Fig. 1) to reduce the force of the spring 33 and thereby reduce the braking force of the band 6. In a modification, the lever 20 is pivoted at its left hand end, the band 6 is connected to the lever intermediate its ends and a spring device is connected to the right-hand end of the lever 20 by a roller engaging the top edge of the lever which curves downwards. In a second embodiment (Fig. 2) brake drums 43 are driven by gears 42 from the warp beam 41 and a band 44 passes round each drum. .One end of each band is anchored by an adjustable spring device 62. The other end is connected to a lever 46 pivoted at 47. A lever 48, also pivoted at 47, is connected by a rod 49 and an adjustable spring 50 to a lever 52 pivoted at 52A. The lever 52 is moved as the beam diameter decreases by a roller 57, a lever 56, and a feeler arm 58, thereby decreasing the effect of the spring 50 on the lever 48 and the band 44.

Title: Improvements in surface finishing or polishing apparatus
IPC: B24D13/02
Filed: 1947-04-15
Abstract: 622,887. Abrasive tools. SCRIVENER, Ltd., A., and SCRIVENER, A. April 15, 1947, Nos. 9954/47 and 2502/48. [Class 60] A surface finishing or polishing tool, particularly for metallic surfaces of irregular  contour, comprises an annulus a of non-metallic material of a mouldable character, e.g. natural or synthetic indiarubber, impregnated with finely divided abrasive to such an extent, say between 50 per cent and 80 per cent, that the annulus is of a substantially solid and rigid character; the periphery is grooved or channelled at a<SP>1</SP> to a depth of about quarter of an inch, preferably during moulding, to form ribs or tongues a<SP>2</SP> which function in the manner of the bristles of a brush, the periphery being thus deformable under pressure to conform to any irregularity in the work contour. The annulus a is bonded to a ring b detachably clamped between a plate d<SP>2</SP> and a flange d' on the hub which is integral with the shaft d the parts d<SP>1</SP>, d<SP>2</SP> being secured by bolts c. The periphery of the annulus may be variably impregnated in zones across the peripheral face thereof so that as the workpiece is progressed across the peripheral face it is subjected to varying degrees of surface hardness in the different zones commencing on a zone of highest impregnation and finishing on a zone of least impregnation. Instead of being rotatable, the working surface may be traversable as in the case of an endless band.

Title: Improvements in echo-sounding equipment
Inventor: HASLETT ROY WILLIAM GEORGE
IPC: G01S15/96
Filed: 1960-03-21
Abstract: 908,905. Echo-sounders. KELVIN & HUGHES Ltd. March 17, 1961 [March 21, 1960], No. 9968/60. Class 40 (7). It is argued that the probab ility of fish caught by a trawl, i.e. the ratio of the number or weight of fish caught to the number " seen " on a sonic or ultrasonic pulse-echo sounder indicator, is a function of radius from the sounder transducer within the range of depths covered by the height of the trawl, Fig. 1 (not shown). According to the invention, the echo signal amplifier 12 gain is time-varied to compensate for attenuation due to range and absorption and wave scattering in the sea, and the amplifier output over a predetermined depth range is weighted by amplifier 19, which may be a PNP transistor circuit. Amplifier 12 output, Fig. 4b, comprises sea bed 26b, and fish, 24b, 25b echoes. Magnetic recorder control circuit 17 generates a waveform, Fig. 4c, the positive-going edge 27 being triggered by the sea bed echo selected by amplitude gate 18 and initiating reproduction, Fig. 4d, from drum 14, the reproduction being terminated after a predetermined interval by tail 28. The output of gate 18, Fig. 4e, incorporates lagging edge 30 which occurs after an adjustable delay produced in unit 21 and which initiates sweep waveform 31, Fig. 4f, to afford time-varying gain characteristic 32, Fig. 4g, of amplifier 19, the output of which is represented by 24a, 25a, Fig. 6a. Circuit 34 provides a rectified output, Fig. 6b, with noise suppression by clipping at levels +x, -x, Fig. 6a. Capacitor 36 charging and discharging, exemplified by the output of cathode follower 40, Fig. 6c, is of either of the forms shown, thereby depending on the capacitance of the capacitor; discharge is effected by a trigger circuit 39. The output of differentiator 41, Fig. 6e, triggers blocking oscillator 42, the output pulses, Fig. 6f, of which are counted by a decade counter 43 which incorporates electronic discharge counting devices. In a modification, Figs. 3 and 5 (neither shown), the signals recorded on the magnetic drum are reproduced several times before the receipt of the next set of signals to be recorded, the corrected and weighted echo signals ensue from the second of the reproduction cycles, and the subsequent cycles of reproduction feed a cathode-ray tube display device. In a further embodiment, the reproduced signals are amplified at fixed gain and then passed through a time gate and an amplitude gate to a counter; the counter output voltage is multiplied by the weighting control signal. The weighted signal is subsequently integrated and then applied to a counter or other display device. Specification 785,001 is referred to.

Patent HU-T52720-A (HU)
Title: Pressing apparatus and method
Inventor: STEWART CHARLES L
IPC: B21C23/20
Filed: 1987-03-04
Abstract: An indirect extrusion process, and apparatus therefor, for producing an extrusion product from a hot metal billet. A press container is mounted to be substantially axially stationary during extrusion of a billet. A hot billet, a die and a pressure disc are located into the axial throughbore of the container so that the billet is sandwiched between the die and pressure disc, with the pressure disc having a maximum outer diameter between opposite radial faces which is slightly less than the diameter of the axial throughbore to define a diametrical clearance between the pressure disc and the press container. A bolster is located adjacent the pressure disc and is axially fixed to substantially prevent axial movement of the pressure disc in a direction toward the bolster during extrusion. The bolster exerts a relatively insigificant axial force against the container. An elongated stem having an axial passage is moved into the throughbore of the container to press the die toward the bolster, causing the billet to be extruded through the die to create an extrusion product which exits the container through the axial passage in the stem, while extrusion of the billet through the diametrical clearance between the pressure disc and the container is substantially avoided.
