Title: Improved means for indexing intermittent rotary motion particularly for straight bar knitting machines
Inventor: LYNAM JOHN EDWARD
IPC: D04B11/00
Filed: 1951-11-12
Abstract: 727,070. Knitting-machines. COTTON, Ltd., W. Nov. 6, 1952 [Nov. 12, 1951], No. 26448/51. Class 74 (2). The screw racking mechanism for the carrier end-stops or the narrowing fingers has indexing mechanism associated with it which comprises locking mechanism which is operated to allow racking of the screws and also to allow uninterrupted locking between successive racks of the screws. For this purpose, a spring- loaded plunger 16 has edges 20, 21 engaging square-cut shoulders 19, 22 of a notch 17 in a disc 15 to prevent accidental movement of the screws between successive racks of the screws by pawl-and-ratchet mechanism 2, 3, 4, 5. When it is desired to rack the screws a thrust-rod 6 is actuated by a cam 8 to raise a lever 29 which through linkage 28, 25 withdraws the plunger 16 from engagement with the disc 15. Due to a lost-motion connection 12, 13 between plunger 6 and a lever 11 operating the pawls 4, 5, this retraction of the plunger is achieved prior to the racking movement. Upon the plunger being withdrawn and the lost-motion of the connection 12, 13 being taken up, the lever 11 is moved to actuate the pawls 4, 5 and simultaneously the lever 29, which is pivoted to lever 11 is moved with the lever 11, to cause the plunger to be released so that it engages the disc 15 and will register with a notch on completion of the racking movement. The rod 6 then returns to its initial position and allows the mechanism to be reset ready for the next racking movement, the plunger 16 remaining engaged with the notch in the disc 15 until it is again withdrawn by the actuation of the rod 6.

Title: Telegraph signal transmission system
IPC: H04L12/52
Filed: 1970-06-02
Abstract: 1278141 Digital data transmission INTERNATIONAL STANDARD ELECTRIC CORP 2 June 1970 [6 June 1969] 26629/70 Heading H4P A digital data exchange includes a store having locations for each outgoing line in which are recorded the character being or to be transmitted on that line. The outgoing lines are grouped according to common characteristics which are recorded in a control word for each group held in separate other locations of the store. The control word includes a 2-bit word indicating the number of bits per character, a 4-bit word indicating the length of a bit, a 4-bit word indicating the position within a character of the bit currently being transmitted and a 4- bit word indicating the duration of the current bit left to transmit. Each control word is read several times per bit and upon each reading the 4-bit word indicating, in terms of number of reading cycles, the length of bit left to transmit is reduced by 1 and the control word rewritten in store. Upon this 4-bit word reaching zero the next character bit has to be transmitted, so that before proceeding to the control word of the next group of lines, the line storage locations of the present group are read in turn. A set of bistables for the corresponding group of output lines which determine their state (0 or 1) are set according to the read data. The control word is updated by increasing by 1 the 4-bit word indicating the position in the character of the bit being transmitted and resetting the 4-bit word indicating the length of bit left to be transmitted. The control word is then rewritten. When in a control word the 4-bit word indicating the bit position reaches zero the whole character on that group of lines has been transmitted and a stop bit is automatically transmitted. Fresh characters are added to the line storage locations from a queue store upon transmission of the stop signal. Start and stop signals limit a message and the idling and out of service state of the line may be continuous stop or start signals.

Abstract: 1,049,327. Electron microscopes. PHILIPS ELECTRONICS & PHARMACEUTICAL INDUSTRIES CORPORATION. July 5, 1963 [July 5, 1962], No.26756/63. Heading H1D. In an electron microscope in which the electron beam from the gun strikes the target and is then focused on to a luminous window, the conical walls of the focusing electromagnets are so shaped that they cannot be struck by fringing electrons over most of their length; each of the cylinders forming the column has a frustoconical axial bore pointed towards the gun, the apex of the cone being nearer to the cone than the pole faces of the adjacent magnetic lens. This reduces the build-up of stray charges from oil vapours, dust particles &c. on the column walls. The tubular members, forming the conical walls of the focusing magnet, may be slid into the central channel of the apparatus, spaced by non-magnetic members and secured by a locking nut. Vacuum seals may be made between the ferromagnetic members 62, 53, 81, 83 (the Figure, not shown) &c. by ring gaskets 81, and the tube evacuated from both ends through the pipe 86. Stigmator coils 41 and 42 are held in the non-magnetic member 46 adjacent the specimen. A camera may be mounted in the tube.

Abstract: 1,041,067. Radio glide path beacons. STANDARD TELEPHONES & CABLES Ltd. July 5, 1963, No. 26826/63. Heading H4D. A radio beacon for indicating a glide path to aircraft, of the type wherein a pair of overlapping directive lobes are radiated, having different amplitude modulation tones on the same carrier, the glide path being indicated by the ratio of the degrees of modulation at the two tones on the carrier as received by the aircraft, comprises a plurality of aerials arranged at different heights, and including two groups of aerials each group being energized to contribute to a respective one of the directive lobes only. One unillustrated embodiment comprises two aerials radiating a pure carrier wave at heights of h and 3h, where h is the height of a radiating aerial to produce a first maximum, and 3h the second maximum, of field strength at the glide angle, and respective intensities 6e and - 2e, and two groups of three aerials, one group being energized with the 150 c/s. sidebands, and the other group being energized with the 90 c/s. sidebands. The arrangement of the aerials and their excitation is given in the following table:- The incremental height #h is introduced so that the two sideband lobes are positioned with their directions of maximum intensity either side of the glide path. The sideband radiation at heights of 2(h + #h) and 2(h - #h) is provided to produce a differential modulation sensitivity adjustment and to produce greater linearity in the region of the glide angle. The lobe, intensity/ elevation distribution produced by this beacon is as shown in Fig. 4, A being the 150 c/s. sideband lobe, B the 90 c/s. sideband lobe, and C the carrier lobe. A development of the abovedescribed beacon is shown in Fig. 3, for a glide path angle of 2¢ degrees, when h is found to be about 5À75#. The single aerial at height h radiating an amount 6e of the carrier, is replaced by four aerials b, c, f and g, energized by equal amounts, whilst the aerial at height 3h, radiating an amount - 2e of the carrier now becomes aerial l, energized by the same amount as the other carrier aerials, but in phase opposition thereto. The 90 c/s. sideband aerials become aerials d, j and k, whilst the 150 c/s. sidebands are radiated from two aerials only, e and n. A clearance radiation lobe D, Fig. 4 (not shown), is further provided, to produce a large " below glide path " indication, by means of aerials a, h, j and m, which are energized by small amounts of the 150 c/s. side band signal, in phase quadrature with that applied to aerials e and n.

Abstract: 841,827. Rollers. SUCKER G.m.b.H. GEB. Sept. 5, 1956 [Oct. 8, 1955], No. 27118/56. Class 42 (2). [Also in Group XIII] A method of maintaining between two coacting rollers which are urged towards one another by a force applied to their respective journals, a contact pressure which is constant over the entire roller length, consists in applying an additional force to a portion of at least one of the rollers to vary its shape. In Fig. 1 a hollow roller 3 is supported on two bearings 4 carried by an eccentric shaft 5. In Fig. 3, an electromagnet 9 acts through the non-magnetic wall of the roller 3 on the magnetic wall of a roller 10. A cylindrical coil may be used instead of the magnet 9. In a further embodiment, an electric element, steam or hot air is used to expand the central portion of the roller which has a non-uniform wall thickness. The heater may be controlled by means responsive to deformation of the roller. A temperature gradient may also be produced by cooling the end portions of the roller. The pressure between the rollers and the member used for varying their shape may be adjusted in accordance with the peripheral speed of the rollers so that when they are used in an impregnating or dressing machine the finished fabric will be uniformly treated.
