Patent GB-1463201-A (GB)
Title: Code readout apparatus
IPC: G06K7/00
Filed: 1974-03-22
Abstract: 1463201 Bar code reader TOKYO SHIBAURA ELECTRIC CO Ltd 22 March 1974 [26 March 1973] 12879/74 Heading G4M A reader for bar codes comprises a hollow cylinder containing a light source or fibres supplying light from a light source, and a transmission path supplying reflected light from the centre of a reading area to one detector and from a portion surrounding the centre to another detector. The detectors may be coupled to the light emitting end of the cylinder by a central fibre core and a surrounding fibre sleeve both of which may carry light from the source (Fig. 5, not shown) or both of which may be surrounded by a further fibre sleeve carrying light from the source (Fig. 2, not shown). The cylinder 21 may contain an inclined reflecting surface 31 having a central hole passing light from the central area to one detector 27 with light from the outer area being reflected by the surface to a second detector 28 (Fig. 4). Alternatively a 3 x 3 matrix of semi-conductors may receive a focused image of the reading area (Figs. 6, 7, not shown). Signals from the detectors are amplified and fed to a differential circuit 43 to form signals (Fig. 12b) which are fed to threshold circuits 44, 45 forming black level pulses (Fig. 12c) and white level pulses (Fig. 12d). These set and reset flip-flop 46 forming pulses (Fig. 12e) which are differentiated by circuit 47 to form pulses (Fig. 12f). The threshold circuits feed counters 48, 49 responsive to the trailing edge of the pulses and reset by delayed pulses from circuit 47 to reach a count of 2 only when a broad mark or space respectively is achieved and to produce via decoders 52, 53 pulses (Figs. 12h, 12i respectively). A counter 58 coupled to flip-flop 46 counts the number of marks in a character and via decoder 59 and delay 60 produces an enabling pulse (Fig. 12n) for AND gates 57 at the end of each character. Decoders 52 and 53 set a flip-flop 55 which feeds a register 56 shifted by pulses (Fig. 12k) so that when pulse (Fig. 12n) occurs the shift register holds the data read from the document. A slightly modified circuit is illustrated in Fig. 13 (not shown).

Patent GB-131578-A (GB)
IPC: B23K37/02
Abstract: 131,578. Davis-Bournonville Co., (Assignees of Bucknam, W. C.). Aug. 23, 1918, [Convention date]. Perforating or dividing by fusion.- In a portable gas-cutting apparatus for circular or straight line cutting of the type in which a wheeled blowpipe carriage is traversed by variablespeed gear and in which a radius rod with centre projects beyond the side of the carriage away from the blowpipe, the centre may be positioned either beyond or between the front wheels of the carriage, so as to increase the range of circular cuts. The carriage 1 which has front wheels 2, 3 and a third castor wheel 4 with fixing screw 5 in alinement with the wheel 2, has an inwardly projecting radius rod 34 on which the bearing 33 for the wheel 3 and the bearing 39 for the centre 38 are removably clamped so that by slipping them off the rod 34 and replacing them, the centre may be placed between the wheels for cutting small circles. A weight 43 ensures the centre maintaining its position during circular cutting, the wheel 3 being raised from the base and the castor wheel freed. The carriage is traversed by a motor 6, preferably electric, the shaft of which carries a pair of spur gears of different sizes, either of which engages one of a pair of gears on the shaft 12, Fig. 3. This shaft has a worm 16 engaging a worm wheel 17 which is mounted with the wheel 18 on a sleeve rotatable about the shaft 15. The wheel 18 engages a wheel 19 on the countershaft 20 on which is mounted a handoperated slidable wheel 21 so as to engage any of the gears 14 on the shaft 15. Motion is communicated in either direction to the worm shaft 26, vhich drives the wheels 2, 3 by worm and spur gearing, by bevel gears 23, 26<a> This variable-speed gearing may be replaced by a frictional speed regulator. The blowpipe slide 46 is carried by an outwardly projecting arm 45 secured to the post 44, and is adjusted by a hand-operated screw 47 to vary the radius for circular cutting or to execute a straight line cut with an offset or jog in it or other irregular cutting, the carriage being either stationary or in movement in the latter ease. A perforated ear 50 carrying a journal 51 is secured at any angle on the slide 46 by a bolt 49. A sleeve 52 carrying at right-angles thereto the blowpipe holder sleeve 56 is mounted on the journal 51 and is adjustable thereon by a worm 54 and worm segment 53. The blowpipe 37 is adjusted in its sleeve by a rack and pinion 57, 58. A shield 59 is secured to the side of the carriage between the mechanism and the blowpipe and may have an inward front extension. The carriage may travel directly on the work or upon a track or any other underlying surface, the wheel 3 being adjustable on the radius rod to suit the gauge of the track for straight-line cutting.

Title: Means for automatically controlling a variable speed power transmission mechanism on a mechanically propelled road vehicle
Inventor: DEAN JOHN ROBERT
IPC: F16H61/02
Filed: 1950-05-26
Abstract: 705,660. Change-speed control.LUCAS, Ltd., J, Aug. 15, 1951 [May 26, 1950], No. 13273/50. Class 80 (2) An accelerator - controlled speed - responsive electro-suction shift between the top two ratios of a three- or four-speed gear on a vehicle comprises a centrifugal switch, rotated by any part of the transmission mechanism., and having normally open contacts u, v, closed at successively increasing speeds, in series with switch contacts g, which latter are closed through a Bowden cable by release of the accelerator m to complete an energizing circuit of a solenoid 2 of two-way relay contacts 3, the lower of which then opens a solenoid valve e communicating the engine inlet manifold with a piston b to move a gear-shift quadrant g anti-clockwise from the next-to-highest ratio position shown, to high. In the high position a spring-loaded detent i, electrically released by the previous opening of the upper relay contact 3, falls over a shoulder h, locking the shift quadrant g against return movement and at the same time opening contacts k to de-energize the solenoid valve e. Thus above the closing speed of both the centrifugal contacts u, v, upshift is obtained at any time by momentary accelerator release. A solenoid operated catch controlled by the detent switch k may be combined with the operating lever of the accelerator switch q to hold the throttle closed until the quadrant g reaches high-speed position. On depressing the accelerator pedal m from idle position, the contacts q are opened, but energization of the relay-solenoid 2 is maintained through its lower contact 3, the centrifugal switch contacts u and normally-closed contacts s operated by accelerator kickdown as described below. Downshift occurs automatically by the opening of the lowest-speed switch contact u, to de-energize the relay-solenoid 2, the upper contact 3 of which energizes a solenoid j retracting the detent i to permit a spring c to return the shift-quadrant g to the next-to-high position shown. During this movement the shift-quadrant g may temporarily cut the engine ignition. Accelerator kickdown shift is produced by the opening of the kickdown contacts s which deenergizes the relay-solenoid 2, resulting in the same downshift sequence as for the opening of the centrifugal contact u above described. In parallel with the kickdown contacts s are further normally open centrifugal. switch contacts w which close at a higher predetermined speed than u or v, and prevent kick down shift above that speed. The shift-circuit is fed through contacts 5 closed only by movement of the usual manual shift-lever to the high position. The system may have a free-wheel between the engine and change-speed gear, or a throttlecontrolled main clutch.

Title: Improvements in or relating to precast reinforced concrete beams
IPC: E04C3/22
Filed: 1951-06-05
Abstract: 695,243. Beams. JAMPEL, S. May 14, 1952 [June 5, 1951], No. 13341/51. Class 20(iv) A precast reinforced concrete beam for floors, or roofs, comprises a number of preferably hollow precast concrete blocks a having at least one end of their upper surfaces transversely chamfered as at b for pointing with mortar &c. and having one, or more, longitudinal grooves in their lower surfaces for receiving metallic reinforcements c. One, or more, longitudinal grooves for reinforcements may be formed in the upper surfaces of the blocks. In order to build up a beam the blocks a are laid end to end in an inverted position and a reinforcement c is placed in each uppermost groove each of which is then filled with mortar, or fine. concrete. A rigid member, e.g. a board, is clamped to the unit over the grooves and then the unit is inverted, the transverse chamfered surfaces which are now upppermost being filled with mortar &c. and reinforcements being placed in any top longitudinal grooves provided and the latter being filled with mortar, or fine concrete. This method may be reversed i.e. by first filling the tranverse grooves, reversing the unit, and then filling the grooves in the underside. A further method comprises placing the blocks on their sides and pointing the grooves &c. in this position. A solid block d, Fig. 1, can be cast against an end block to seal. the ends of the grooves of the beam and to accommodate the hooked end of the reinforcement. A floor, or roof, Fig. 4. may be formed by placing a number of beams side by side and tying them together with a number of transverse solid blocks f placed in line between the hollow blocks a and having a transverse duct to receive a stressing element g. The spaces between the units are filled with fine concrete. When the concrete has set the elements g are stressed e.g. with a hydraulic jack to give a series of transverse prestressed ribs.

Filed: 1943-08-17
Abstract: 587,473. Coating fabrics successively with adhesive and powdered material. STEVENS, A. H. (Behr-Manning Corporation). Aug. 17, 1943, No. 13361. [Class 140] [Also in Groups II and XXIII] Comminuted material, e.g., abrasive grains or fibre flocks, is passed through an electrostatic field of alternating polarity and the frequency of the field is controlled to separate the finer sized particles and apply them to an adhesive coated backing, such as paper or cloth or a combination of paper and cloth. The coarser particles may be separately removed and collected, or may be applied to the same backing on top of the finer grains. There are simultaneously passed through an electrostatic field of alternating polarity produced between electrodes or banks of electrodes 3 and 6 an endless travelling belt 10 carrying a layer of abrasive grains from a hopper 9, and a backing 1 of adhesive-coated paper. The applied voltage is generally sufficient to lift all the grains from the belt 10 and the frequency is adjusted so that only the smaller grains reach and stick to the adhesive coated backing while the larger grains drop back. Some or all of the larger grains may be subsequently applied over the smaller grains in a second field of lower frequency or of constant polarity produced between electrodes 4 and 7. Any rejected grains fall off the belt 10 while passing around roller 13 and may be used for making coarser sandpaper. The spacing of the electrodes may be uniform or may decrease as shown towards the exit end. The specification indicates the voltages and frequencies suitable for use with specified grades of abrasive grains. Alternatively the smaller sized particles removed by the alternating field may be secured by a temporary adhesive such as water, which may contain a wetting agent or starch, to an endless belt, from which they are later removed by means of a vibrator and/or a rotating brush while passing through a heated chamber.
