Abstract: 686,139. Overload-release clutches. BRONZAVIA. Oct. 24, 1950 [June 2, 1950], No. 25882/50. Class 80 (ii). An overload-release clutch between a driving drum 2 and a driven shaft 4 comprises fingers 8 pivoted to a block 5 fixed to shaft 4 and normally held outwards in engagement with notches 3 in drum 2 by toggle springs 12 active through telescopic rods 16 each pivoted at one end to the block 5 and carrying at the other end a pin 17 bearing on a profiled part 18 of the finger 8, as shown in the left-hand part of the figure. Upon the occurrence of overload, the fingers turn, compressing the springs 12 until the axis of the spring passes the dead centre relative to the face 18, whereupon the pin 17 slides along the face 18 and the spring acts abruptly to swing the finger 8 into the inoperative position shown in the right-hand part of the figure. The clutch is reset by pulling the fingers outwards.

Filed: 1961-07-19
Abstract: 906,757. Dressing grinding wheels. CHANDLER, H. July 19, 1961, No. 26106/61. Class 60. A multi-diamond tool for dressing grinding wheels comprises a holder 14 and two or more slugs 16, Fig. 2, carried thereon, each slug having a diamond tip, and each being individually adjustable whereby the tip may remain in the same position relative to the holder, but the diamond is re-orientated to present a fresh cutting edge. Each slug is rotatable about its own axis and may be locked by a screw 18 in any selected rotational position; the axes of the slugs are inclined at a small angle to the axis of the tool shank and converge thereon in a plane beyond that containing the tips. Each tip may be formed by the end of a single elongate diamond or by small diamonds or fragments arranged in layers in known manner, the diamond or diamonds being set in a hard metal matrix mounted on a stem of softer metal. The plugs are secured in the holder by a dowel 17 engaging a peripheral groove 13 formed on each slug. When three or four slugs are used, they are arranged in a common plane across the holder with their inclined axes converging on a common point on the axis of the tool shank, but when groups of five or more slugs are used they are arranged as in Fig. 10, their axes also converging on a common point. Dressing may be effected with the shank of the tool normal to the grinding wheel axis or slightly inclined thereto in a plane containing the wheel disc.

[Class 83 (iii)] In a filing-machine of the type having an endless chain and carrier 12 carrying files 13 the carrier is guided adjacent the work by a channel shaped member 15 having portions engaging directly, Fig. 5, with the longitudinal edges of the rear faces of the files. The file carrier passes over a fixed lower pulley 7 driven from an electric motor 8 and a resiliently mounted upper pulley 10 carried on a lever 11 and normally urged upward to tension the carrier by a spring 31 or by a weight. The work-table 14 is angularly adjustable and the file carrier is pressed into its guide channel 15 by a roller 23 on an arm 16. The files 13 have inclined teeth with their adjacent ends cut to an opposite inclination. The file carrier consists of long channel section links 17 to which the files are attached by screws 27, shorter channel section links 18 and pairs of links 19 disposed within the channel links and connected thereto by pivot pins 20 the links 19 being engaged by spring pins 25 to impart a positive drive to the carrier. The pins 20 fit closely in holes in the links 19 but have reduced end portions which engage loosely in holes of the same size in the channel links. Leaf springs 24 normally maintain the carrier in stretched condition and prevent the pins 20 from falling out endwise. One of the channel links may have a hooked end coacting with its pin to permit the positioning or removal of the carrier. The links 17 may be punched up at 26 to form projections engaging in recesses in the files. The tension of the carrier may be relieved by an eccentric 29 operated by a hand lever 30,

Abstract: 1518185 Charging batteries PRO CASA-GES REG TRUST 20 June 1975 [26 June 1974 28 Jan 1975] 26346/75 Heading H2H A method of charging a battery 14 comprises monitoring the battery voltage after the voltage at which gassing commences has been reached, sensing a reduction in the rate of increase of the battery voltage and causing a charger 15 to be switched off or switched from a boost charge mode to a trickle charge mode when the rate of increase is substantially zero. The charger is connected to a power supply 16 via the contacts of a relay 17. A differential amplifier 20 compares the battery voltage with the voltage of a capacitor charged from a constant current source in a control device 21, the charging of the capacitor being started when the battery voltage reaches the gassing point. An amplifier 24 holds the contacts of the relay 17 closed to supply a boost charge to the battery until the capacitor voltage equals the battery voltage whereupon the relay 17 is de-energized.

Title: Production of diketene
Inventor: LACEY RICHARD NORMAN
IPC: C07C45/88
Filed: 1955-09-15
Abstract: Diketene is obtained from ketene by dimerizing it in the presence of diketene and acetic anhydride and removing the heat of dimerization of the ketene.  It is preferred to have present at least 50 per cent of acetic anhydride based on the weight of diketene and acetic anhydride together.  The process may be carried out continuously or batchwise.  Suitable temperatures for carrying out the process are 0-70 DEG  C. and preferably 10-40 DEG  C. Desirably, acetic anhydride is added continuously to the reactor to maintain the diketene to acetic anhydride ratio at a constant level.  An example is given.

Abstract: 1,175,324. Telescopic umbrellas. BREMSHEY & CO. 4 June, 1968 [10 June, 1967], No. 26486/68. Heading A4P. A telescopic umbrella comprising threepart spokes, a stick in at least three parts, a main slider, main struts pivoted at one end to the main slider and at the other end to the inner end of a middle spoke part, and a lock between each middle and outer spoke part which engages automatically when the spokes are being extended and is released by the inner spoke part when they are being telescoped, has a handle in which the thickened ends of the outer spoke parts are held by an axially slidable locking member which, during extension of the frame, is retained in the locking position by a positive lock operated by the middle stick part, at least until the locks between the middle and outer spoke parts have engaged. The locking member 31 is fixed to the lower end of a tube 4 sliding on the lower stick part 3, which has the greatest cross section of the three stick parts, when the locking member moves axially between the limits defined by the handle 6. In the locking position, wherein the spoke tips 11 are locked in an annular space 38 bounded by a flange 32 and a collar 37, the tube 4 is restrained from sliding movement by a locking nose 40 on a tongue 39 stamped out of the lower stick part, the nose engaging a hole 41 in the wall of the tube. the middle stick part 2 has a sloping lower edge 42 which comes inside the tongue as this stick part moves down inside the lower stick part and retains the lock in position, keeping the locking member 31 in the spoke-retaining position until the stick parts are extended. A friction lock near the crown, consisting of a U-shaped spring with projecting noses, see Fig. 5 (not shown), retains the auxiliary slider in a position adjacent to the crown, preventing movement of the auxiliary struts and hence of the main struts and middle spoke parts, until the outer spoke parts have been pulled out of the middle spoke parts.
