Abstract: 885,169. Adjusting fluid pressure brakes. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. Feb. 12, 1960 [Feb. 20, 1959], No. 5857/59. Class 103 (1). In a brake-operating cylinder and slack adjuster arrangement comprising a piston 13 connected to a piston rod formed in two parts 17, 18 which are relatively rotatable one within the other to vary the length of the rod, the part of the piston rod which is adjacent the piston is connected thereto via trunnions 22, 23 which permit the piston rod to rock in a plane through the axis thereof and means is associated with one of the trunnions for producing relative rotation of the parts of the rod to reduce slack in a mechanism operated thereby. In the embodiment illustrated where Fig. 2 is a section of the line II-II of Fig. 1, when fluid under pressure is introduced into cylinder space 36 movement is transmitted by the piston 13 and through the piston rod assembly 17, 18 to the brake rigging through trunnion block 21. Should the travel of the brake cylinder piston exceed a predetermined amount, rollers 34 riding along beyond a cam profile presented by two spaced-apart ramps 35 so that the lever 32 is allowed to rock in a clockwise direction to permit the movement of pawl carrier 26 pivoted at 27 under the influence of compression spring 29 in trunnion 22 to cause the movable pawl 28 to ride over the ratchet wheel 19 to engage the next tooth. Subsequently. during the return stroke of the piston the roller 34 ascends the rise of the cam profile and the movable pawl carrier is returned to its original position against the action of the spring 29 taking with it the movable pawl such that the ratchet wheel is turned one step in the direction to elongate the piston rod to take up the unwanted slack. Specification 577,576 is referred to.

Filed: 1969-02-05
Abstract: 1281083 Banded fibres formed by film fibrillation SMITH & NEPHEW RESEARCH Ltd 3 Feb 1970 [5 Feb 1969] 6132/69 Heading B5B A longitudinal array of interconnected fibres, the individual longitudinal fibres of which are continuously bonded along their length by possessing successive regions of different crosssectional area, degree of orientation and morphology, may be formed by (a) taking a sheet or tape of synthetic polymeric thermoplastic material having on one or both sides or within its thickness a regular or irregular pattern or arrangement of regions of different morphology such that longitudinal sections along the sheet or tape show regular or irregular differences respectively in such morphology, and (b) stretching the sheet or tape longitudinally at a stretch ratio and temperature such as to produce a longitudinal array characterized in the manner described above. The expression "differences in morphology" is defined as meaning structural differences or the surface and/or within the thickness of the film, especially those relating to size, shape and arrangement of the polymer crystallites. The fibres in the array may possess alternate thick and thin portions or alternate solid portions and multistrand portions. In the example, the fibres of the array consist of polypropylene The array may be formed into a bundle of substantially separate fibres by application of a separating energy. The array may be twisted to form a yarn or may be chopped to form staple fibres. In the process of forming the array the differences in morphology may be caused by a random or a regular pattern of irradiation of the film, of differential cooling of an extruded melt forming the film, or of perforations in the film. The perforations may be flame perforations. The differences in morphology may correspond to differences in film thickness. The film may have on at least one surface a regular pattern of discrete raised embossments and the embossments may be hexagonally packed on the surface. The film may have on at least one surface a regular pattern of discrete depressions, or a regular pattern of two intersecting sets of parallel straight intersecting grooves, or on one surface a set of parallel grooves and on the other surface another set of parallel grooves, the two sets lying in intersecting directions. The film may have non-longitudinal grooves at an angle to the transverse direction. The film may be provided with a herringbone pattern or with generally longitudinal parallel wavy lines.

Title: Improvements in locking mechanism
IPC: E05B55/00
Filed: 1946-03-01
Abstract: 608,022. Locks. LARSSON, S. A. I. March 1, 1946, Nos. 6479 and 6480. Convention dates, March 3, 1945, and July 24, 1945. Addition to 587,300. [Class 44] The lock according to the parent Specification is modified by the provision of a swinging link connected to the bolt and guided in the movable guide. When the bolt is unsecured, the link is coupled to the guide so as to move therewith when the handle is turned and when the bolt is secured, it is moved by the key into a position in which the guide is free to move idly so that the handle may be turned without moving the bolt. The lock is shown in section in the drawings, being unsecured in Fig. 1 and secured in Fig. 4. The guide 21, which comprises two parallel bars, is moved by a cam 38 on the handle spindle 8 engaging a sloping rear part 37. The swinging link 27 carries a transverse pin 34 normally co-operating with a shoulder 39 on the guide 21. To lock the bolt 3, the link 27 is tilted downwards (Fig. 4) by the key 7 which engages between rearwardly extending prongs so that the lower prong 32 abuts a fixed member 29. The pin 34 is now positioned opposite a slot 41 in the guide 21 so that it can move idly. The spring 24 is threaded on the guide 21 between the ends 42 and two plates 22 which bear rearwardly against fixed guides 14 on either side of the guide 21. The plates 22 carry cams 36 which make a click as the pin 34 passes over them from one position to another. The ends 42 are accommodated in a slot in the bolt 3 when the bolt is unsecured, but are withdrawn to compress the spring when the handle is turned and the bolt is secured. A recess 55 is provided in the guide 21 behind the ends 42 to facilitate mounting the spring. One modification consists in shaping the recess between the prongs on the link 27 so that the key is turned into a vertical position when the bolt is retracted. In another, instead of providing an abutment on the member 29, the pin 34 is arranged to engage shoulders on the fixed plates 14 to lock the bolt against retraction when the link 27 is tilted downwards. The cam 38 may be provided with springs to return it to the normal position and recesses to receive the springs.

Title: Improvements in snap-action electric switches
Inventor: JAMES MICHAEL JOSEPH
IPC: H01H5/18
Filed: 1956-03-01
Abstract: 805,683. Retractive switches; actuation of switches; switch cases. DOWTY EQUIPMENT Ltd. Feb. 28, 1957 [March 1, 1956], No. 6489/56. Class 38 (5). A snapping blade 1 has a cut-out 2 and lugs 6 ... 8 resting on the bottom of recesses 10, 13, 14 on the switch base 9, the contactcarrying end 4 being crimped or set so that the blade is normally curved longitudinally and transversely to the configuration shown in Figs. 4, 5 in which a fixed contact 16 is engaged. To reverse the switch, a dimple 26 on a spring blade 25 engages the blade midway between lugs 6, 7, whereby increased downward pressure is imparted to the contact 4 to compensate for the diminishing curvature of the blade until it snaps over. As the pressure produced by the blade 25 is withdrawn, the blade 1 snaps back to its original position, the contact-pressure being compensated as before. To produce the movement of blade 25, the cover 11 contains a push-button 31 having a conical part 36 which acts on a ball 37 in a recess 38, the ball bearing on the blade 25 through the intermediary of a metal plate 39 and rubber sheet 29. The casing parts 9, 11 have flanges 27, 28 respectively, and sheet 29 is enclosed within flange 28 and engaged by flange 27 to produce a water-tight joint. Current is led from pin 23 to the contact 4 by way of a spring sheet 22 having three limbs which fit into recesses 10, 13, 14 under the lugs 6 ... 8. In a modification (not shown), the blade 1 is continued beyond the lugs 6, 7 to provide a second curved blade, so producing a double-break switch. Also, the curvature may be produced by transversely lengthening the fixed end of the blade. The Provisional Specification states also that the blade may be stiffened by laminating for greater current-carrying capacity, or made of bimetal for temperature sensitiveness.
