Title: Improvements in or relating to mechanism for damping lateral oscillation or whippingof a rotating shaft
IPC: F16F9/10
Filed: 1932-03-19
Abstract: 390,940. Damping lateral oscillations of shafts. VEREINIGTE KUGELLAGERFABRIKEN AKT.-GES., Schweinfurt, Bayern, Germany. March 19, 1932, No. 8185. Convention date, March 23, 1931. [Class 108 (iii).] In means for damping the lateral oscillations of rotating shafts, small movements are damped by liquid and movements of larger amplitude by solid friction. The shaft 1 rotates in bearings in a carrier 5 supported by a spherical surface 6, rotation of the carrier 5 being prevented by pins 16 which do not interfere with its oscillating movements. The lower end of the carrier 5 extends downwards into an oil reservoir and carries a number of rings 7, 8 which are alternately of large and small diameter, the smaller rings fitting on the carrier so as to move sidewise with it at all times. The rings are compressed by a helical spring 10 When the carrier 5 oscillates about its spherical support 6, the oil in the reservoir exercises a small retarding effect, but when the angular movements are sufficient, the larger rings 7 make contact successively with the wall 9 of the reservoir. The relative lateral movement thus produced between the large and small rings provides an increasing braking effect. In a modification the spherical seat 6 is carried directly on the upper end of the reservoir. In a further modification, the spherical support is replaced by an annular disc of flexible material. The outside diameter of the larger rings 7 may increase progressively downwards. The rings may be of double conical shape, as shown in Fig. 9, to increase the retarding effect.

Title: Protective device for electrical circuits and apparatus
IPC: H02H3/33
Filed: 1957-03-13
Abstract: 830,018. Protective cut-out systems. GERRARD, M. C. March 11, 1958 [March 13, 1957], No. 8236/57. Class 38 (5). A protective system includes a relay or breaker B having contacts which may isolate a protected apparatus 27 from the supply and an operating coil 17 energized by a potential derived from the voltages across two pairs of conductors, one conductor being an earth conductor, so that if the sum of the voltages is substantially below its correct value the relay or circuit-breaker will remain open. Thus, in Fig. 1, a transformer T has two primary windings 8, 9 connected respectively between the neutral and line conductors 2, 4 and the earth and line conductors 3, 4. The transformer secondary winding 10 is connected to the operating winding 17 through earth connections E<SP>2</SP>, E<SP>1</SP>, the metal frame or casing 29 of the protected apparatus 27, auxiliary contacts 20 of a circuit-breaker A and contacts 21 of a differential current relay C. When the operating push-button 23 of the circuit-breaker A is fully depressed, the contacts 20 are closed and coil 17 is energized to close the circuitbreaker B. On the release of the push-button 23, a spring 24 returns the moving parts of the circuit-breaker A to a position in which the contacts 20 are open but the main contacts are held closed by a mechanical linkage (indicated at M) extending from the circuit-breaker B, the circuit for the coil 17 being maintained through the earth and neutral conductors 3, 2, back to the point at which the supply neutral is earthed. If there should be a break in any of the main conductors or if these conductors are not correctly connected, either or both of the windings 8, 9 are not energized and both circuit-breakers A, B open and/or circuitbreaker B cannot be closed. If any part of the circuit between the winding 10 and the coil 17 is broken, or if an earth leakage fault causes the operation of the relay C then the coil 17 is de-energized and the circuit-breakers open. To protect against overheating, the insulation 28 of the appliance 27 may be such that its resistance falls quickly above a predetermined temperature, the resulting current leakage to earth causing the relay C to open. A fullwave rectifier may be connected between the secondary winding 10 and the circuit it supplies to prevent incorrect operation due to stray A.C. potentials between neutral and earth, Fig. 3 (not shown). The circuit-breakers may be opened by the operation of a push-button switch 13 which interrupts the supply to the windings 8 and 9 and has a mechanical link for resetting the relay C.

In a one-piece multiple-ply collar, the band region of the ply 3 which will be furthest from the neck in wear is made slightly longer than the ply 1 nearest the neck and the collar is made by placing the shorter ply 1 with the interlining on the plate 2 of a work-holder and superimposing a spacer member 4 and the longer ply which are clamped down by a member 11 so that the spacer bends the top ply 3, causing its periphery to coincide along three sides which are joined by a running stitch 14. The collar is then turned and the excess material along the fourth side is held in even distribution along the length of the collar by stitching a seam adjacent the fold-line with a sewing-machine having the usual presser foot replaced by a roller 16 (Fig. 5, not shown). Alternatively the longer collar may be stretched on a work-holder as described in Specification 736,129.

Title: Improvements in or relating to the production of soluble salts of methylchlorophenoxyacetic acids
IPC: C07C51/50
Filed: 1949-03-28
Abstract: Water-soluble salts of 2-methyl-4-chloro-phenoxyacetic acid are obtained in solid form or as stable concentrated solutions by treating the crude liquid reaction product of chlorinated o-cresol and chloracetic acid (see Specification 573,479), with acid at a raised temperature under the conditions set out in Specification 623,217 and neutralizing the molten 2-methyl-chloro-phenoxyacetic acids with alkali together with sufficient water, if desired, to produce a concentrated solution of the salts.  The 4-chloro-isomer represents 70 per cent of the mixture of isomers obtained and a concentrated solution so produced will contain 36-50 per cent of the mixed salts, i.e. 25 per cent or more of the 4-chloro-isomer. The crude starting-material may contain 5-20 per cent of mixed salts. The alkali is preferably used in about 0.5-1.7 per cent excess of theoretical and is run in at such a rate that the pH is maintained at about 11; the product will then contain about 1.8-6 per cent of free alkali based on the weight of the salt, the latter comprising at least 65 per cent of the whole.  The alkali may be carbonate, sodium hydroxide being preferred.  The alkali may contain from 0-84 per cent of its weight of water, depending on the form in which the product is to be obtained; if solid, the water formed in the neutralization is subsequently removed.  A solution containing 60-70 per cent of caustic soda is preferred. The starting material may be freed from chlorocresol by the method of Specification 592,827, i.e. steam distillation after partial acidification.  Examples are given of the processes of the invention.

Abstract: 861,759. Casting-machines. DIE CASTING MACHINE TOOLS Ltd., and MILLS, A. R. March 10, 1959 [March 17, 1958], No. 8481/58. Drawings to Specification. Class 83 (1). In a die-casting machine there is provided a switch which is closed when the die-plates are together, a switch operatively controlled by the die-closing toggle links to be closed when the toggle links are locked, and electric circuit means operative only when both switches are closed to complete an electric circuit for initiating operation of a solenoid-controlled valve for a fluid-pressure-operated piston-and-cylinder assembly for injection of the material into the die. A microswitch is closed by the die toggle links when the dies close, and is incorporated in an electronic valve circuit which provides a delay before actuation of said solenoid valve. A further delay period may be provided for ensuring automatic opening of the dies after injection has been completed. The machine may include die brushing means as disclosed in Specification 811,873, which is referred to, and other switches inhibit die-closing until the brush is fully withdrawn, and initiate brushing when the dies are open. Two other switches in series are positioned diametrically opposite each other on the movable die platen, to prevent injection unless the dies are closed. The circuit also includes upper and low-level probes in the pot from which the molten metal is injected into the dies, so that a ladle is actuated when the level falls below the bottom probe to fill the pot up to the level of the top probe. A pressureresponsive switch in parallel with a safety cutout switch forms a safety device as disclosed in Specification 842,380 which is referred to, to interrupt a power-supply circuit if there is any obstruction between the die plates. The machine may be switched for manual, singlecycle, automatic or automatic repetitive operation.
