Title: Improvements in or relating to internal shoe drum brakes
IPC: F16D65/22
Filed: 1949-06-17
Abstract: 668,869. Vehicle brakes. AUTOMOTIVE PRODUCTS CO., Ltd., and CHOUINGS, L. C. June 9, 1950 [June 17, 1949], No. 16212/49. Class 103 (i). A spreading means for a brake of the kind in which a spreading device acts between the adjacent ends of two shoes to displace either or both of said ends outwardly and comprising a housing slidably mounted on the brake shoe support, a bell-crank lever pivotally mounted in the housing so as to be movable about its pivot by operating means connected to one arm thereof, and a thrust member disposed between the other arm of the bell-crank lever and one of the brake shoes is characterized in that the thrust member is pivotally connected to the said other arm of the bell-crank lever and projects through one end of the housing, the arrangement being such that movement of the bell-crank lever about its pivot to apply a thrust through the thrust member to the one shoe produces a reaction at the pivot of the bell-crank lever which is transmitted through the housing to the other shoe. The spreading device consists of a housing 17 formed from folded plate as the sides and ends of a box of which the open bottom slidably rests on a thin metal plate 35 in contact with the inner face of the back plate 10. The housing is apertured to receive a pin 23 on which are pivoted a pair of spaced plates 26 which carry between them an eyebolt 27 secured at its outer end, through the medium of a spring washer 38, against a pressed cap 36. The washer 38 clamps the cap 36 and the housing 17 against opposite faces of the back-plate 10, which is slotted at 34 to accommodate an inverted U-shaped member 25 which guides the housing in its sliding movement on the back-plate. The plates 26 are formed into a bell-crank lever by the provision of pins 29, 23 upon which are respectively pivoted a link plate 30, notched at 41 to engage one brake shoe and a pull-rod 33 connected to an operating mechanism. The end of the housing opposite the notch 41 of the plate 30 is provided with an adjuster (not shown) of the type described in Specifications 595,322 and 595,343, which engages the other shoe, so that rocking movement of the bellcrank 26 applies a force to one shoe through the link 30 which is reacted on the other shoe through the slidable housing 17 and the adjuster.

Title: Improvements in or relating to electric arrangements for measuring in radio frequency circuits
Inventor: DUNKLEY ROWLAND ARTHUR GEORGE
IPC: G01S13/34
Filed: 1951-07-13
Abstract: 681,078. Measuring the time delay of a circuit. STANDARD TELEPHONES & CABLES, Ltd. July 13, 1951, No. 16662/51. Class 37. The time delay of a circuit 1 is compared with that of a standard circuit 2 by applying to each frequencies f1, f2, respectively, modulated by a frequency q, combining the outputs to produce a frequency f 3 which is frequency-modulated by q and which varies in frequency according to the difference in time delay of the two circuits, and demodulating f3 to obtain q which varies in amplitude according to the difference in time delay of the two circuits. A master oscillator 4 has its frequency traversed over a range by a saw-tooth generator 5, and is frequency-modulated by a sinusoidal oscillator 6 of frequency q. The resulting oscillations are applied over couplers 7, 8, mixed with oscillations FŒf from 9, detected at 10 and applied to filter 12 to produce a frequency f1 which varies uniformly over a range and is frequency-modulated by q. Similarly, couplers 7, 13, oscillator 14, detector 15 and filter 16 producing a frequency f2 with a range of uniform variation and frequency-modulated by q. The frequencies f1, f2 differ, so that after passing through the networks 1, 2, when modulated at 17 they yield a frequency f3 frequency-modulated by q. The deviation of f3 depends on the relative time delays of the circuits 1, 2, so that after passing through a frequency discriminator 19 the oscillation of frequency q is obtained, and its amplitude varies with the difference in the time delays of circuits 1 and 2. After rectification at 20, the signal may be read on a voltmeter 21 or displayed on a cathode-ray tube 3 whose time base is provided from the saw-tooth generator 5. The cathode-ray tube thus displays the variation of time delay with frequency. The circuits 1, 2 may be connected between the couplers 7 and 8, and 7 and 13, the frequencychanging of 8, 9, 10, and 13, 14, 15 being performed on the outputs of the circuits 1, 2. To provide a frequency scale on the oscillograph, detector 11 and filter 26 are fed from coupler 8 to provide frequency f varying over a range; this is modulated at 27 by a fixed frequency f from 28 to provide in the output of low-pass filter 29 a frequency varying over the range but starting from zero. After rectification, this is applied to a second set of plates in the cathode-ray tube. Since the oscillation fed in from coupler 8 is frequency-modulated at frequency q, side-bands of the type fŒnq will occur, where n is an integer, so that as the frequency is swept over the range, the frequency supplied to 27 will repeatedly pass through the valve f to give a short output pulse from 29. Thus the cathode-ray tube will be marked by a series of pulses spaced apart by the frequency q. The rectifier 30 can be omitted, the marks then becoming short lines. The detector 11 and filter 26 can be omitted, the modulator being fed from filter 12.

Abstract: 1,253,701. Electromagnetically - controlled brakes; controlling clutches. ELITEX, ZAV. ODY TEXTILNIHO STROJIRENSTVI, GENERALNI REDITELSTVI. 31 March, 1969 [8 April, 1968], No. 16690/69. Headings F2E and F2L. [Also in Divisions D1 and H1] Electromagnetic clutches 11, 20, 14, 41 and brake 26 are operated in sequence in a spinning machine by a rotating control finger (Fig. 2, not shown), operating on switches 45, 46, 47, 48 adjustably positioned on a circular plate around the control finger. When start button 51 is depressed and motors 32 and 35 are running at full speed, relay 61 operates contact 611 to disengage brake 26 and engage clutch 20 and contact 612 to open the circuit of clutch 41. The opening of the circuit of clutch 41 initiates rotation of the rotating control finger. The moving control finger operates switch 46 and its relay 62 to engage clutch 11 via contact 621. The control finger then operates switch 47 and its relay 63 to disengage clutch 20 and engage clutch 14 via contact 631, close contact 632 to close the circuit of clutch 41 and thereby stop the rotation of the control finger, and close contact 633 to bridge switch 47 and keep the spinning machine running. The spinning machine is stopped by depressing button 52 which interrupts the running of the motors 32 and 35 and de-energizes relays 61 and 62. The circuits of clutches 11 and 41 are thereby opened and the latter clutch initiates rotation of the control finger again using the inertia of the machine as it slows down. The moving control finger de-energizes relay 63 which disengages clutch 14 and engages brake 26. Under inertia the control finger continues to rotate to close switch 45 so that clutch 41 is energized from capacitor 26 and the control finger is thereby stopped.

Title: Improvements in or relating to collapsible containers made of or comprising tinned lead
IPC: B65D35/14
Filed: 1941-12-30
Abstract: 554,415. Making collapsable and other containers. BRUUN, O. J. Dec. 30, 1941, No. 16788. [Classes 83 (ii) and 83 (iv)] Soldering; squirting.-Two surfaces of a collapsable or other container comprising tin or lead having a tin-lead interface at the region of the surfaces are bonded together by pressing them together under the application of heat so that a tin-lead eutectic compound is formed commencing at the tin-lead interface, which compound after cooling unites the surfaces together. If one of the parts is composed wholly of tin heating must be effected above the melting point of the eutectic, i.e. 1830 C. but below the melting point of tin, i.e. 232 ‹ C. so as to avoid damage to the tin part, but if both parts are tin coated lead this temperature, though preferable, is not essential since the formation of the eutectic stops when all the tin at the heated region is consumed. The temperature must, however, in this case be below the melting point of lead i.e. 327 C. A tube may be extruded from a slug punched out of a composite sheet made by rolling together a tin sheet 2 and lead sheet 1 which produces a tin-lead compound 3 at the interface. The slug or the sheet prior to forming the slug, may be coated with a flux which may contain tallow, vegetable or mineral oils with or without resin, sal ammoniac or zinc chloride to serve as a lubricant in extrusion and as a flux in the bonding operation. The filling end of the tube may be closed by pressing the tinned surfaces together with a heated tool to produce the tin-lead eutectic 9. The end may be folded prior to bonding. The tin coating may alternatively be on the outside or each side may be so coated. A nozzle may be similarly bonded by its flange 10 to a shoulder at the upper end of the body 5. The nozzle may be of tin and body of lead coated with tin to produce the eutectic bond 9, Fig. 12. The eutectic first forms between the coating 6 and body 5. In a modification the nozzle may be of tin and the body of lead. In a further modification, Fig. 15, the body may be of lead and the nozzle of lead or other metal or non-metal coated with tin 12. In a modification of this form the body may also be coated with tin. The terms tin and lead include the metals not in the pure state.
