Rotary tipplers; gantries.-Relates to tipplers of the kind in which the rotary carrier is raised and then tipped by winding drums on the superstructure. The carrier e is arranged at one of the outer sides of the structure a without towers or pillars at the side of the carrier remote from the side towards which it is tipped. The winding mechanism c, c' is carried on a projecting portion a<1> of the superstructure, which overhangs the carrier, and the hoisting and lowering ropes d pass down under the carrier at f and up to an anchorage near the tipping axis g. The carrier is guided during hoisting and tipping by rollers i - - i3 engaging guides h, h<1>, h<2>, k on the superstructure. The wagon delivers into a bunker, hopper or shoot b for loading vehicles and trucks below or to one side thereof. Weights m guided in the superstructure are arranged to balance only the weight of the carrier and the carrier is lowered more rapidly than it is raised. The ropes m<1> carrying the balance weights m are connected to bent links o pivoted on the cradle at i' and provided with rollers r running in the guides h<1>. The wagon is held on the carrier whilst tipped by a fixed lateral supporting beam e<1> and a sustaining beam t carried on arms a pivoted on the superstructure and balanced by weights y. The beam t may instead be carried by the longer arms of a pair of levers pivoted on a horizontal axis, the shorter arms of the levers being engaged by the rollers i on the cradle.

Title: Improvements relating to apparatus for measuring the deformation of materials under compression and tension
IPC: G01N3/14
Filed: 1944-12-04
Abstract: 584,055. Testing physical qualities of materials. COPE & COPE, Ltd., COTTON, J. H., and COPE, C. J. Dec. 4, 1944, No. 24242. [Class 106 (ii)] In an instrument for measuring the deformation of materials under compression and tension, the application of the load to the test sample is permitted by an electromagnet which is switched off by the operator at the initiation of a test. A platen u is supported from a pivot m on a lever arm k pivoted to the main pillar d of the instrument at j. A weight n tends to lift the platen u which, however, is held down by an electromagnet mounted in the base v. A sample for a compressive test is placed on the platen beneath an abutment x which is adjusted to almost contact the sample. The electromagnet is then switched off and the platen is raised by the leverage of the weight n, the load increasing as the weight descends to compensate for the increasing cross-sectional area of the test piece. A recording is made by a pen 3 on a clock-driven drum (not shown). Samples for tensile tests are carried by hooks 11 and 12, and in this case the lever arm k is reverted and mounted in the lower position (shown dotted) so that the load decreases as the cross-sectional area decreases.

Abstract: 814,730. Knitting. PLANCK, A. Aug. 23, 1955 [Aug. 25, 1954], No. 24275/55. Class 74 (2). A method of knitting a welt for 2 Î 2 rib knitted articles on a two-bed machine, for example, a cylinder-and-dial machine comprises the steps of feeding a yarn 1 to form a draw course on all the needles of both beds situated in a 1 X 1 formation, casting off the loops of the draw course from all of the needles of one bed, for example, the cylinder needles U1, Z1, Z2, feeding a yarn 2 to all of the needles of both beds to form an initial course of the welt and knitting the yarn 2 so that the loops of yarn 1 of the draw course on the needles of the other bed, that is the dial needles U2, R1, R2, are cast off these needles about the loops of the yarn 2, Fig. 1. Thereafter a yarn 3 is fed to the pairs Z1, 22 of the cylinder needles and a yarn 4 is fed to the pairs R1, R2 of the dial needles, these needles being situated in a 2 Î 2 formation. After having knitted these yarns 3 and 4 and cast off the loops of yarn 2 from the needles Z1, Z2, R1, R2, the loops of yarn 2 still retained by the intervening needles U1, U2 are transferred by these needles to one of the needles of the pairs of needles in the other bed as shown by the loops S in Fig. 2. Normal 2 Î 2 knitting on the needles Z1, Z2, R1, R2 is then continued the needles U1, U2 remaining inoperative. Alternatively the loops S may be spread over and taken by both needles of the pairs. In another embodiment, Fig. 3, the intervening needles U2 on the dial or transferring loops are not employed, the draw course 1 is knitted in 2 Î 2 formation which is subsequentl;y cast off the cylinder needles. The yarn 2 is then fed to all the operative dial needles and to the intervening needle U1 and one needle Z1 of each pair Z1, Z2 of the cylinder needles, knitting then taking place so that the loops of the yarn 1 are cast off the needles R1, R2. The yarn 3 is then fed to the dial needles R1, R2 and the other needle Z2 of the pairs Z1, Z2 in the cylinder and the yarn 4 is fed to the cylinder needles Z1, Z2 and, after the knitting of yarns 3 and 4, the loops of yarn 2 remaining on the intervening needles U1 are then transferred to one or both of the needles of the pairs of the dial needles R1, R2. Thereafter 2 Î 2 rib knitting continues.

Title: Vehicle cleaning apparatus
IPC: B60S3/06
Filed: 1973-05-22
Abstract: 1416628 Vehicle cleaning apparatus TAKEUCHI TEKKO KK 22 May 1973 [25 May 1972] 24487/73 Heading B7J A vehicle cleaning apparatus comprises a pair of parallel fixed guide rails 2 arranged on opposite sides of a portal frame 1 and extending forwardly downwardly relative to the intended direction of travel of a vehicle V to be cleaned through the portal frame, a trolley 3 having an adjustable constant torque motor 6 to drive it along the rails 2, and a pair of side brush units including substantially vertical brushes 15 mounted on the trolley 3 for movement towards and away from one another transversely of the direction of vehicle travel. Each brush 15 is tiltably suspended from a respective wheeled carriage 14 which can travel along an associated one of two aligned guide tracks 11 carried on the trolley 3 and inclined downwardly towards each other transversely of the vehicle travel direction. Prior to a vehicle cleaning operation, motor 6 drives the trolley 3 along the rails 2 to the upper end thereof. The arrival of a vehicle which exerts force against the brushes 15 stops the motor 6 when its torque setting has been exceeded, so that the trolley then descends the rails 2 under gravity at a speed equalling that of vehicle movement. At the same time the brushes 15, which are initially positioned together as shown in Figs. 1 and 2, are slightly tilted by vehicle contact, thus operating switch means to start drive motors 17 which drive the carriages up the tracks 11 until further switch means are contacted. This stops the motors 17 and allows the carriages 14 to roll back to bring the brushes 15 into contact with the vehicle sides until the rear of the vehicle is reached, whereupon the constant torque of the motor 6 is adjusted to maintain the same pressure upon the vehicle surfaces when its rear is cleaned as that previously provided for the front and sides.

Title: Improvements in or relating to braking systems for the landing wheels of aircraft
IPC: B64C25/46
Filed: 1929-08-12
Abstract: 338,139. Russell, A. E., and Bristol Aeroplane Co., Ltd. Aug. 12, 1929. Force-transmitting mechanism.-The anchor plate 10 of an internal expanding aeroplanewheel brake is freely mounted on the axle 11 and is restrained against rotation by a cable 23 attached to a fixed part of the machine. The cam-actuating lever 19 is limited in its movement by an adjustable stop 22 co-acting with the hinge of a toggle 16 having one lever arm 17 secured by a fitting 18 to the axle 11 and the other 15 being fixed to plate 10. Cable 23 is given an initial tension causing the hinge of the toggle 16 to bear against the axle. If the braking torque exceeds a predetermined value, the plate 10 will rotate, stretching the cable 23 and causing the lever 16 to straighten thereby forcing the stop 22 and lever 19 toward the " off '' position, thus relieving the braking pressure. In a modification, the cam-operating lever extends beyond its fulcrum and is provided with an eye through which passes a rod attached to some fixed part of the machine and having an adjustable stop nut by which the angular movement of the cam-operating lever is limited. Rotation of the brake anchor plate due to excessive torque causes the fulcrum of the cam-operating lever to move relative to the adjustable stop, thus causing the lever to rotate in the reverse direction to relieve the braking pressure.

Title: Novel phosphate and salts thereof and the manufacture of same
Inventor: ATHERTON FRANK RATCLIFFE
IPC: C07F9/12
Filed: 1955-08-30
Abstract: The invention comprises 2-carbamyl-phenyl phosphoric acid, its sodium, magnesium and calcium salts, and the manufacture thereof by phosphorylating salicylamide with tetrabenzyl pyrophosphate in the presence of an alkalimetal alkoxide, catalytically hydrogenating off the benzyl groups of the dibenzyl 2-carbamylphenyl phosphate so formed, and, where a salt is desired, treating the acid with the appropriate alkali-metal or alkaline-earth-metal hydroxide.  In the example, salicylamide is reacted with tetrabenzyl pyrophosphate in a solution of potassium t-butoxide in t-butanol.  The resulting dibenzyl 2-carbamyl-phenyl phosphate is hydrogenolysed using a pre-reduced catalyst prepared by hydrogenation of Adams palladium oxide and palladium charcoal, to form the 2-carbamyl-phenyl phosphoric acid.

Abstract: 653,206. Refrigerating. NICHOLS, T. W. Sept. 23, 1948, Nos. 24856 and 27083. [Class 29] [Also in Group XXIX] Means for cutting off quickly the flow of liquid refrigerant from the liquid receiver; connected to a union 13 to the evaporator, via a union 14, in a refrigerating machine, when the compressor stops, comprises a bellows 10, Fig. 1, attached to the closure member 8 of an expansion valve and connected by a union 15 to a point between the suction non-return valve and the suction inlet of the compressor. When the compressor stops, the suction and delivery non-return valves close and the pressure of the fluid trapped in the compressor is equalized at the suction and delivery sides. The increased pressure at the suction side acts in the bellows to thrust the member 8 to its seat. When the compressor is running the member 8 is controlled by a bellows 2 subject to the evaporator pressure which is substantially equal to the suction pressure and thus the bellows 10 is balanced. In a modification the bellows 10, Fig. 3, controls a separate closure member 8 and is connected through the union 15 to a point between the compressor delivery outlet and the delivery non-return valve. When the compressor is running the bellows is balanced by liquid receiver pressure through a union 13 and a spring 17 opens the member 8. When the compressor stops the decrease of pressure at the delivery side permits the liquid receiver pressure to seat the closure member In another arrangement the member 8 and its bellows are mounted in a separate housing.

Title: Improvements in or relating to electrical frequency measuring devices
Inventor: STUDD ALAN GEORGE
IPC: G01R23/02
Filed: 1957-08-07
Abstract: 851,453. Frequency measurements. SMITH & SONS (ENGLAND) Ltd., S. Nov. 7, 1958 [Aug. 7, 1957], No. 24940/57. Class 40(5). In a frequency measuring device of the averaging type in which a capacitor 8 charges, and discharges through a D.C. meter 9, on alternate half cycles of a signal, the average current through the meter being an indication of the frequency of the signal, means are provided to pass a current, derived from the same frequency discharging current, but independent of-the frequency thereof through the meter 9 in opposition to the discharge current of the capacitor so that a zero meter reading can be obtained at a non-zero frequency. Such an arrangement is used for the measurement of an unknown frequency higher than the known chosen frequency, the meter then giving a direct indication of the difference frequency. A zener diode 2 is connected across the input terminals 3, 4 and across caapcitor 8 and rectifier 7 the input alternating voltage having a peak amplitude in excess of the zener voltage so that the output from the diode 2 is a series of pulses of the same frequency as the input signal. When the diode 2 is conducting in the reverse direction at the zener point the rectifier 7 conducts and capacitor 8 charges, and when diode 2 conducts in the normal forward direction capacitor 8 discharges through the meter 9. The full wave rectifier voltage between the negative terminal of diode 6 and the positive terminal of diode 2 (of amplitude equal to the common zener voltage) causes a current which is independent of frequency, to flow in meter 9 through resistance 5, zener diode 6 and resistances 14-10 in opposition to the discharge current. This reverse current can be adjusted by variable resistance 14 and the range of frequencies which the meter can measure by potentiometer 11. Resistor 5 and diode 6 may be omitted and resistor 14 connected directly to the negative terminal of diode 2 when the reverse current flows mainly when capacitor 8 is charging. A thermister 16 is provided to compensate for temperature variation.
