Title: Improvements relating to screw lifting devices, but particularly for milling machines and like machine tools
Inventor: O'NEILL JOHN JOSEPH
IPC: B66B9/02
Filed: 1960-05-03
Abstract: 925,995. Screw-and-nut gearing. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. April 27, 1961 [May 3, 1960], No. 15589/60. Class 80 (3). In a safety device limiting the fall of a vertical rotatable screw 10, supporting a load such as a machine tool table, following wear or damage of the threads between the screw 10 and its fixed nut 11, an idle nut 18, which on failure of the nut 11 can seat on a thrust bearing 17 to support the load, is coupled non-rotatably to the nut 11 by pins 20 which uncouple after an amount a of axial movement. The distance a is equal to the amount of wear expected before failure of the nut threads. As wear occurs in the nut 11 the nut 18 moves closer to the bearing 17. As the nut fails the screw falls a distance A-a to seat nut 18 on bearing 17. During the fall the pins 20 become disconnected so that subsequent rotation of the screw 10 does not raise or lower the load, thereby indicating the failure of the nut 11. An aperture 21 allows inspection of the spacing A, which indicates the extent of wear in the nut 11. The pin connection 20 may be replaced by a splined or castellated connection.

Abstract: 1302571 Fibrillar assemblies SOKO CO Ltd 2 April 1970 [5 April 1969 2 Oct 1969 6 Oct 1969 25 Oct 1969(2)] 15621/70 Heading B5B A synthetic fibrillar assembly is made of a thermoplastic polymer and each fibril has a stem 1 of relatively large width, a plurality of branches 2 randomly integral with the stem and a plurality of numerous fine hairs 3 extending at random from the stem and branches, the entire configuration thereof being crimped and twisted at random. The fibrils may have polygonally profiled transverse cross-sections varying from branch to branch, from hair to hair and from stem to branches and/or hairs, and, further, may be provided with numerous peripherally and internally formed fine crevices. The use of polyolefins, especially polypropylene, is exemplified. Such a fibrillar assembly may be made from an unorientated web of films which is drawn longitudinally at an elevated temperature and at a draw ratio sufficiently high to render the film fibrillatable, and by then fibrillating thefilm web 14 by drawing it further in a drawing zone 13 in which the linear speed at which the web is drawn into the zone by rollers 11 is less than the linear speed at which the fibrillated web 15 is withdrawn from the zone by rollers 12, the draw ratio in the drawing zone being high enough to effect fibrillation but not so high as to rupture the fibrillated film web. In the apparatus of Fig. 6, the rollers 11 and 12 are preferably peripherally curved by elastic layers 11c and 12c to improve the nip on the film. Alternatively, the apparatus of Fig. 7 (not reproduced) enables a stable, firm nip on the film to be obtained. In that of Fig. 9, the film web 14, after having been rendered fibrillatable by longitudinal drawing, is fibrillated by further drawing in two or more stages 17 and 18, the speed at which the web is fed into each drawing stage being lower than the speed at which it is withdrawn therefrom. The apparatus of Figs. 10 and 12A (not reproduced) may be used similarly. Fig. 13 shows a modified form of the apparatus of Fig. 9, in which the intermediate rollers 16 are replaced by the pair of endless travelling belts or "apron rollers" 19, which are driven at speeds higher than those of the feed rollers 11. Fig. 12 (not reproduced) shows a modificacation of the apparatus of Fig. 13. In the apparatus of Fig. 16, one or more of the intermediate rollers 20 are cone-shaped rollers, driven so that their surface speed at their largest diametral portion is smaller than that of the downstream rollers 12 and their surface speed at their smallest diametral portion is larger than that of the upstream rollers 11.

Title: Improvements in and relating to electric fuses
IPC: H01H85/38
Filed: 1938-05-25
Abstract: 499,254. Electric cut - outs. BRITISH THOMSON - HOUSTON CO., Ltd. May 25, 1938, No. 15632. Convention date, May 25, 1937. [Class 38 (i)] An electric fuse consists of a casing 61 containing a number of tubes, 56 to 60, or compartments, through which a fusible conductor 66 is threaded back and forth. The tubes are filled with arc-quenching material and the element passes from one tube to another through holes, such as 67 to 70, at points remote, from one another and from the terminal caps 62 and 63, in order to prevent short-circuiting arcs. Some of the tubes may be filled with gas-producing arc-quenching material and the others with inert arcquenching material. Holes 64 are provided in the terminal caps to allow gases to escape, and porous discs 65 prevent the escape of filling material. Holes 73 are also provided in the tubes to facilitate the escape of gases. In the form shown in Fig. 1, the tubes 17, 18, 19 do not extend the full length of the casing and the holes 67 to 70 of Fig. 5 are in this case unnecessary. A wire 30 is connected in shunt with a portion of the fusible element 24 and is brought out through the wall of the fuse casing, as at 31, into contact with a small body of gunpowder 32 held in place by a label 33 to indicate when the fuse has blown. The portion of the fuse element 24 in shunt with the wire 30 is weakened as at 34 so that fusion starts there. In the modification shown in Fig. 7, the indicator consists of a brightly coloured plunger 100 held down against the action of a spring 103 by a strain wire 101 one end of which is passed, with the fusible element, through a hole 96 in one of the tubes and is anchored to the tube. When the fuse blows, the strain wire is also ruptured, for example by the arc formed, and allows the plunger 100 to be projected.

Abstract: 699,375. Compressed-air engines. LUCAS (INDUSTRIES), Ltd., J. July 1, 1952 [July 3, 1951], No. 15737/51. Class 122(iii) In a compressed air operated windscreen wiper mechanism embodying a parking valve a manually operable lever actuates the parking valve and also opens a spring-loaded air supply valve moved by its spring to its closed position under the control of a reciprocatory part of the mechanism. Two spaced pistons b reciprocable in cylinders a are connected by a bar c having thereon a rack d engaging a pinion e that imparts oscillatory motion to the wiper arm. Compressed air is supplied to a chamber f via a spring-loaded poppet air valve k and is admitted alternately to the cylinders a by a distributing valve loaded with an over-centre spring h and moved by a rocker g actuated by tappets i on the bar c. The stem of the air valve k engages a notch t in the bar c when the pistons are in the parked position and the air valve is opened by one end of a manually operable lever o whose other end carries a rack q engaging a complementary rack r on a pivotally mounted parking valve associated with the distributing valve. In the position shown the wiper is parked and to operate it the lever o is rotated clockwise to open the air valve k, disengage the valve stem from the notch t and move the parking valve to its inoperative position by the racks q, r. The wiper mechanism then operates in the normal manner until the lever o is returned to its initial position thus releasing the air valve and returning the parking valve to its operative position. Due to obstruction by the bar c; however, the valve k remains open and the pistons continue to move until the parking position is reached when the notch t comes opposite the valve stem and allows the valve to be closed by its spring m.

A block of cigarettes, e.g. two rows of ten cigarettes each, is removed from a feed table 2 by a rotatable member 16 to enable feelers 23 of sensing devices 22 to test whether all the cigarettes are present or whether any cigarettes are faulty, before the block is returned to the feed path 2. The cigarettes are removed-from the bottom of a shoot (26), Fig. 3, not shown), by a pusher (11) of an intermittently moved pair of endless conveyer chains (6). The block so formed is received from the conveyer (6) into a slotted open-ended pocket 17 of the member 16 which lies in a gap 5 in the path 2. The member 16 then rotates to carry the block between the feelers 23 which are moved in against the ends of the block by rod and linkage mechanism (24, 25). The feelers 23 exert a control effect in known manner if the block is faulty. The pocket 17 carrying the block returns to the level of the table 2 and the block is removed by the pusher (11) standing upstream of the gap 5 in the table. In a modification, the member 16 is replaced by a slide (116), Fig. 6, having two slotted pockets (117) and (1171). Two pairs of sensing devices (122) are provided, one on each side of the feed table (102). The block may be discharged from the pocket 17 when the pocket is in its uppermost position.
