Abstract: 1,174,435. Temporary roadways. HARVEY ALUMINUM, Inc. 20 July, 1967 [3 Jan., 1967], No. 33464/67. Heading E1G. In a temporary road or runway formed by interconnecting a plurality of hollow rectangular extruded metal mats, preferably of aluminium, each mat comprising deck and base plates 19, 17 integral with vertical or other parallel webs 21 and having interlocking side formations, as shown in Fig. 4, the mats are articulated end to end by coupling bars 10 of H, X, C or other section loosely engaging at least one inwardly facing channel 26 on the end of each mat, each channel 26 being formed by cutting away the ends of the webs and side formations and inturning the projecting end of the deck or base plate. In the embodiment shown the projecting ends of both plates 19, 17 are curved inwardly to provide two undercut channels cooperating with lobes 47 on the coupling bar. The deck plate may be thickened at 22 midway adjacent webs 21, the thickened portions being removed from the projecting ends. The end of the coupling bar is flattened and apertured for removal, and protrudes to fill the corner gaps between adjacent mats.

Title: Improvements in or relating to shaft or rod couplings
IPC: F16D3/06
Filed: 1922-12-07
Abstract: 216,906. Ter Cock, C. Dec. 7, 1922. No Patent granted (Sealing fee not paid). Controlling variable-speed gearing; facilitating changing speed.-In axially-moving rods having a resilient part adapted to yield in tension or compression upon excessive resistance being encountered, the resilient part is in the form of a single spring or rubber buffer connected to the rods by universal joints. The device is particularly applicable as a yielding coupling between the actuating and striker rods of motor-vehicle change-speed gears of the type operated by a gatechange lever or semi-automatic mechanism such as described in Specification 194,628, the universal joints allowing for temporary or permanent misalignment of the selector device and gear box. The actuating-rod 1, Fig. 1, is coupled to the striker rod 2 by Hooke's joints 3, 4, a rod 7, and telescopic members 5, 6 connected by a spring 8, which is secured to eye-bolts 9, 10 pivoted on screws 11, 12, and is so stiff as to yield appreciably only to positive resistance, such as clashing gears or clutches. The parts 5, 6 are prevented from relative rotation by grooves 5b and pins 6<a>, which may be replaced by the projecting head and end of the screw 12, or the parts 5, 6 may be non-circular. In a modification, the ends of the spring are bent axially and screw-threaded, one end being screwed into the part 6 and locked by a nut, and the other end passed through the base 5<a> and secured by nuts. In the form shown in Fig. 4, a rubber buffer 17 is held between a washer 18, seating on a nut 20 and a plug member 22, and a washer 19, seating on a shoulder of the rod 16 and a flange 21<a> of the casing 21, so that the buffer yields by compression for either direction of movement. Modified universal joints 14, 15 are shown. The casing 21 is barrel-shaped to allow for expansion of the buffer 17, which may comprise a series of rubber springs with or without interposed metal washers.

Abstract: 1520652 Open end spinning SPINNEREIMASCHINENBAU KARL-MARX-STADT 14 Aug 1975 [16 Aug 1974] 33887/75 Heading DID  An open end spinner comprises staple fibre delivery means, a rotary twist inducer, and a stationary needle secured at one end and having a free end directed towards the twist inducer so that the needle tip exerts a restraining force upon the yarn end formed by the inducer. Stationary needle 7, Fig. 1, extends through cusps of interengaging discs 4, towards twist inducer 6 twisting end 10 of running yarn 11. Fibres 9, delivered from opener 1 by an air stream onto plate 3, Fig. 2, are turned at -right angles due to airflow expansion and the plate, and are applied between the discs to rotating end 10. The fibres in the end wrap and are restrained by the needle. Rotation of the discs and twist inducer in the same direction is said to reduce the false twist effect due to the friction provided by stationary needle 7. Alternatively, Fig. 3, fibres 9 delivered by rollers 12, 13 are oriented in the electrostatic field between the rollers and twist inducer 6, and are wrapped about and located by needle 7. The needle may be curved and/or angle 15 may be 0 to 45‹. Distance 16 may be 10 to 40mm and distance 17 1 to 10mm, and the needle diameter may be 0.1 to 0.5mm.
