Title: Improvements in or relating to agricultural tractors and self-propelled cultivators
IPC: B62D49/06
Filed: 1943-09-28
Abstract: 576,477. Motor vehicles. McCONNEL, F. W., and TRACTORS (LONDON), Ltd. Sept. 28, 1943, No. 15921. [Classes 79 (i) and 79 (iii)] A self-propelled agricultural unit comprises an engine 40 and a land-wheel 17 driven thereby mounted on a main frame, a second steerable land-wheel 25 mounted on a sub-frame which is adjustably secured to the main frame so that the steering axis of the wheel may be offset relatively to the plane of the engine-driven land-wheel, and means for securing to the main frame one or more laterally-extending members, e.g. shafts 47, in order to mount a third wheel for maintaining the unit in upright position or for coupling the unit to another similar unit. As shown, the main frame of a unit consists of upper and lower longitudinals 10, 11 secured by cross-frames 12, 13, 14 and encloses the land-wheel 17, the shaft 21 of which is mounted in bearings 22 in the frame and also carries a sprocket-wheel 24 connected by a chain 45 to a sprocket 44 on the output shaft of a gear-box 42 driven by the engine 40. The steerable land-wheel 25 is mounted in a fork 26 having a shaft 27 rotatable and verticallyadjustable in a frame 29 which is pivoted between cross-members 34 and is securable in the required position by a peg 36 extending through one of a number of holes 37 in a quadrant 35 and a hole in the frame. Hence, the steering-wheel may be offset from the driving-wheel. In the case of a single unit, the third wheel 46 is carried on one side of the main frame by a shaft 47 secured between brackets 49. The cultivating implements are attached to a frame 48 which may be trailed behind the rear wheel or, as shown in Fig. 2, is pivotally mounted on a shaft 51 secured in brackets 50 on the main frame and may be power-raised by abutments or cams 52 on the wheel 1 operating lever-link mechanism 53 having a member 54 moving into and out of the path of the cams 52. To prevent tilting of the unit, e.g. during ploughing, when the third wheel 46 is moving in a furrow and the other two wheels are on unploughed ground, one or more detachable wheel rims may be provided. Another construction is shown in which two units are connected together by the shaft 47 and, if necessary, by a further shaft. The land-wheels may be driven independently by their engines or the two engines connected to a differential gear-box having an output shaft connecting the sprockets 44. The two steering tillers are linked for manipulation from one driving position.

Title: Improvements relating to ring spinning, doubling and twisting machines
IPC: D01H7/60
Filed: 1948-06-15
Abstract: 642,458. Spinning &c. rings. HOWARD & BULLOUGH, Ltd., and TOWNLEY, W. R. June 15, 1948, No. 16088. [Class 120(ii)] In a ring spinning, doubling or twisting machine, the bore of each ring-receiving hole 12 in a ring rail 11 is provided with a plurality of pegs or like projections 13, the lower flanges of the rings 10 being grooved at 14 in such a manner that a ring may enter its hole in a direction normal to the rail surface, with each projection 13 received in a separate groove 14, and thereafter secured by rotary movement about its own axis. As shown, the projections 13 consist of hardened steel balls retained in recesses in the wall of hole 12 by caulking or equivalent means, and the upper parts 142 of grooves 14 are helical and are of gradually decreasing depth so that rotary movement of the ring draws it down on to its seating on the rail and also causes the balls 13 to jam in the grooves to secure the ring in place. The helical parts 142 of the grooves are right- or left-handed according to the direction of rotation of the spindles. Alternative forms of projections 13 may be made of, or covered with, material having a high coefficient of friction, e.g., indiarubber.

Title: A process of producing active silicic acid
IPC: C01B33/152
Filed: 1926-06-30
Abstract: 254,726. Ring Ges. Chemischer Unternehmungen. July 1, 1925, [Convention date]. No Patent granted (Sealing fee not paid). Silica.-Highly absorptive silica suitable for purifying liquids and gases is made by first producing finely-divided silica by reacting upon silicon fluoride with steam or a small quantity of water and then removing adhering water by suction and moulding the silica under pressure into convenient shapes without removal of its "hygroscopic" water. The content of water must be that which the silica gel can absorb from saturated steam so that its pores are full. Even when high pressure is employed, the absorptive power of the material is not reduced. The first stage of the process may be effected by treating silicon fluoride with atomized water. The Specification as open to inspection under Sect. 91 (3) (a) states that the first stage of the process may be effected by passing silicon fluoride into hydrofluosilicic acid. This subject-matter does not appear in the Specification as accepted.

Patent GB-630390-A (GB)
Title: Improvements in processes for stretching artificial yarns
IPC: D06M11/05
Filed: 1947-06-24
Abstract: Yarns of a thermoplastic organic derivative of cellulose are subjected to stretching in their unsoftened state by an amount up to 80 per cent of their extensibility under the prevailing conditions, and are then subjected to further stretching while in a softened condition.  The first stretching may be carried out with the yarn in the dry or wet condition and may be such as to produce a permanent elongation of 2-25 per cent of the original length.  The further stretching may be carried out in the presence of saturated or wet steam or hot water under pressure at temperatures above 100 DEG  C. The further stretching may be such as to produce an elongation of 5-20 or more times the original length.  The two stages of stretching may be carried out in sequence on the travelling yarn.  The yarn may be fed through a pair of rollers outside the steam treatment chamber, then through rollers located in an end chamber adjoining the steam chamber, and then through the steam chamber to a further pair of stretching rollers.  Alternatively, the yarn may be fed through two sets of rollers outside the steam treatment chamber, and then through an injector device into the steam chamber.  Prior to or during the first stretching the yarn may be passed through a trough containing water at room temperature or at a raised temperature, e.g. up to 75 DEG  C., provided that it is not hot enough to soften the yarn.  The process may be applied to single yarns, or to a group of yarns in warp formation, or to large bundles of yarns, e.g. those having initial total denier above 100,000, which are subsequently to be converted into stable fibre.  Staple fibre yarns may be subjected to the treatment.  The yarns may be of cellulose acetate of various viscosity characteristics, or of cellulose propionate, butyrate, or aceto-butyrate, or of ethyl cellulose or of other cellulose ester or ether.  Specifications 438,584, 438,585, 438,586, 438,587, 438,655, 438,656, 443,707, 443,773, 488,794, 526,157 and 558,958 are referred to.  The Provisional Specification comprises also the stretching of polyvinyl, polyacrylic and other thermoplastic yarns.

Patent GB-1494003-A (GB)
Title: Polyphase scanner for bar code symbols
IPC: G06K7/10
Filed: 1975-04-23
Abstract: 1494003 Bar code reader SCHILLER INDUSTRIES Inc 23 April 1975 [3 May 1974 16 April 1975] 16822/75 Heading G4M [Also in Division G3] A reader for bar coded labels, e.g. in a supermarket, has a light beam deflected in two directions to produce a sinusoidal multiphase scanning pattern. A laser beam is reflected from an oscillating mirror 84 on to a multi-faceted rotating mirror drum 88 which directs the beam towards a window 16 over which a labelled article passes. Mirror 84 imparts a sinusoidal movement to the beam and the drum imparts a linear motion to the beam creating a scanning waveform as in Fig. 7. Mirror 84 is synchronized in speed with the rotational speed of drum 88. A light source and detector 114, 116 detect the passage of the junction between two adjacent facets of the drum and supply a pulse on line 112 (Fig. 12). A train of pulses each representing the start of a scan is multiplied by multiplier 118, divided by divider 120 and fed to a galvanometer driver 125 via a gate, a filter and a signal conditioning circuit. Each pulse at the driver causes the mirror to execute one cycle. The scan may include a straight line D1 as well as the sinusoidal scans. As shown in Fig. 7 this occurs once for every three sinusoidal scans so a divide by four circuit 128 is used to disable gate 122 and feed a trigger circuit 132 which causes the galvanometer mirror to hold its present position. An auto reset circuit 134 resets divider 120. The values of the multiplier 118 and divider 120 depend on the number of phase traces to be produced. In Fig. 7 three phases are used each having 31/3 cycles so the mirror must oscillate 31/3 cycles for each facet of the drum. Light reflected from the label is reflected from the drum and fed to a detector 94. The mirror 84 being small obstructs only a small portion of the reflected light. In an alternative embodiment (Figs. 14, 16, not shown) an electromechanical resonator is used to drive the mirror at the natural resonant frequency of the devices and pulses from the resonator are used to drive the drum.
