Title: Improvements relating to vehicle steering gears
IPC: B62D3/10
Filed: 1939-01-18
Abstract: 523,964. Screw-and-nut gearing ; shaft couplings. PEET, A. Jan. 18, 1939, No. 1685. Addition to 509,126. [Classes 80 (ii) and 80 (iii)] The parent Specification describes a vehicle steering gear in which a worm or helically threaded member splined on the steering shaft engages one or more stationary projections, which may be in the form of a screw thread. The object of the invention is to avoid the provision outside the casing or gear box of hollow projections housing the peg or like member engaging the worm. This is effected by making the casing in two parts 3, 5 spaced apart by a block 4 which carries the peg or other projection, in this case a screw thread, to engage the worm. The parts are held together by bolts 10. The worm 6 is splined at 11 to the steering shaft 2 and has a collar 12 adapted to move a roller 7 on an arm 8. The lower end of the shaft 2 is located in a bearing 9. The collar 12 may be separate from the worm 6, Fig. 3, and each have interengaging teeth 14 encircled by a spring ring 15 engaging a circumferential groove in the teeth.

Title: Manufacture of alkyl chlorides or alkyl bromides from olefines or mixtures containing olefines
IPC: C07C17/08
Filed: 1930-01-20
Abstract: Active carbon, used as a catalyst in the production of alkyl halides from olefines and hydrogen halides, is revivified by heating it to 300-1000 DEG  C. in the presence of a controlled supply of steam.ALSO:Hydrochloric acid and/or hydrobromic acid is caused to combine with an olefine or olefines of low molecular weight in the presence of an adsorbent or a mixture of two or more adsorbents, which must be resistant to the action of the acid used.  Suitable adsorbents are solids having a microporous structure and having the property of condensing gases e.g. partly or wholly dehydrated active carbon, including activated charcoal, partly or wholly dehydrated colloidal silica, and naturally occurring siliceous materials, which may have been dehydrated or extracted with acids, such as kieselguhr and "glaucosil."  The reaction may be conducted at, above or below atmospheric pressure, and heat may be added or abstracted as desired. The reagents should be dried and may be introduced separately or together, and the olefines may be diluted with other substances, such as saturated hydrocarbons.  Any residual saturated hydrocarbons may be treated with chlorine or bromine, the hydrogen halide formed being used for treating further quantities of olefines.  The apparatus may be so arranged that the adsorbent may from time to time be removed or cut off from the sphere of reaction so that any product condensed thereon may be removed.  Examples are given of the treatment of pure and diluted ethylene, propylene and butylene, and of pure amylene. The reaction temperatures specified are not above 120 DEG  C. Specifications 209,722, 216,368, and 301,009 [all in Class 2 (iii), Dyes &c.], are referred to.

Title: Machine tool control system
IPC: B23Q35/128
Filed: 1972-01-17
Abstract: 1384253 Optical tracing WESTINGHOUSE CANADA Ltd 17 Jan 1972 [29 Jan 1971] 2103/72 Heading G3N In an optical tracing system, in which a tracer head 17 follows contour information Figs. 1a, 1b (not shown), perpendicular projections (16) (Fig. lb) are detected by the tracer head scanning in circular paths (13) (Fig. lb) and are processed to control, in a defined sequence, auxiliary machine functions such as; tool lowering at zero feed to set levels defined by position detectors 26, 27, 28; stopping; further tool lowering to follow given contour information a pre-set number of times; control of gas supply to a gas cutting machine; energization of direction memory circuit 32 suppressing response to the rearward of the two scanning pulses produced in each circular scan over a contour line. The auxiliary machine functions may also be controlled by manual pulse signals from control panel 24, the existence of a break (Fig. 1a) in a contour line or from tool position detectors 26, 27, 28. Command pulse generator 22, see Fig. 4 (not shown). The optical tracer pulses (a), Fig. 3 (not shown) are fed to monostable delay circuit (34-37), providing a delay corresponding to a 90 degree movement of the tracer head, and, after shaping by pulse shaping circuit (38-41) are fed via line (42) to a coincidence circuit (43, 44) also receiving at terminal (45) an inverted version of waveform (a). Thus only when a perpendicular projection (16) (Fig. lb) is being scanned is capacitor (47) able to charge, and after such projection is scanned a predetermined number of times set by variable resistor (46), a control pulse is fed via comparator (50) receiving a reference potential via Zener (49) to counter 23. For high tracer speed, projection (16) may be extended. Binary counter 23, see also Fig. 5 (not shown) includes circuitry for pulse shaping and to avoid triggering by spurious signals. Function Generator 29, see also Fig. 6 (not shown). The output from binary counter 23 causes the appearance of a signal on successive ones of the output lines of decade counters (58, 59), and diodes, selectively connected between such lines and outputs (a-r) each corresponding to a specific, auxiliary machine function, define the sequence. There may be a plurality of function generators, selectively connected to counter 23, or the diode matrix on a plug in board may be replaced by another, to define a plurality of distinct sequences. Direction memory circuit 32, see also Fig. 7 (not shown) produces, from waveform (g) Fig. 3 (not shown), the waveform (h) ensuring that in the absence of a scanning line, the direction of tool movement is not changed, and that the signals at the rear in the scanning direction do not affect machine operation when a gap is encountered.

Title: Improvements relating to gyroscopes
IPC: G01C19/38
Filed: 1930-01-21
Abstract: 342,880. Gyroscopic apparatus. WARREN, N. H. A., Admiralty Research Laboratory, Teddington, Middlesex, and DRYSDALE, C. V., Admiralty, London. Jan. 21, 1930, No. 2114. [Class 97 (iii).] In apparatus indicating a fixed or slowly moving direction, particularly a compass of the slow wanderer type, the gyro is connected to a follow-up ring and the system comprising the gyro and connecting means is arranged to be in neutral equilibrium about the horizontal axis and is such that when the gyro is tilted the connecting means causes a torque to be applied about the vertical axis only, to counteract or reduce the tilt. The gyro 1 is mounted on horizontal pivots 2 in a vertical ring 3 which is mounted on vertical pivots 5 in the followup ring 6. The connection between the gyro and the ring 6 comprises a bail 7 mounted on the ring 6 on pivots in line with the pivots 2 and connected to' the gyro at a point 8 to one side of the vertical axis 5, 5. The system comprising the gyro and bail is in neutral equilibrium about the pivots 2 so that no torque is produced about the horizontal axis when the gyro is tilted but owing to the eccentricity of the connection 8 a torque results about the vertical axis. The apparatus may be amplified by providing a level-control arrangement rigidly fixed to the gyro-casing to impart north-seeking properties.

Abstract: 1,200,160. Snap-action switches. L. W. BURCH, and H. K. BURCH. 25 July, 1967 [25 July, 1966], No. 2295/70. Divided out of 1,199,957. Heading H1N. On movement of switch actuating member 90 to the left, a wedging member 115 carried thereby slides along a fixed contact member 106 passing between the fixed contact member 106 and the movable contact 102 of a snap-action spring blade 96 and forcing the blade spring 96 over centre to open the contacts. The blade spring 96 is an M-shaped blade like the one disclosed in copending application 34068/67. In its other stable position a contact 104 carried by blade 96 engages a fixed contact 108. These contacts are separated in a similar manner to the first set by a wedging member 124 carried by actuator 90 on return movement of the actuator. Overtravel in either direction causes one or other wedging member 122, 124 to jam the respective contact set 104, 108 or 102, 106 together with increased contact pressure. The wedging members may carry contact bridges on their leading edges to provide a more rapid opening for D.C. operation. In Fig. 5, the wedging members 142, 150 are resilient spring blades which co-operate with respective fixed cam surfaces 144, 152 on overtravel. These cam surfaces deflect the blades 142, 150 after the snap-action blade has passed overcentre to increase the contact pressure of the closed contacts.
