IPC: C25B9/17
Filed: 1916-08-12
Abstract: 108,707. Hepburn, G. G. Aug. 12, 1916. Addition to 12730/15. Cells; electrodes; electrolytes, circulating. - In bipolar-electrode electrolyzers without containers, of the kind described in the parent Specification, the following modifications are made-(1) Electrolyte flows upwards through the cells from a perforated or slotted tube b, Fig. 2, which either forms the movable bottom of each cell, or is situated near a separate movable bottom piece, being then perforated preferably underneath to prevent choking. A pipe b between the top edges of the electrodes may serve as the outlet, or the electrolyte may overflow from the upper ends of the cells as described in the parent Specification, or may passthrough holes g, Fig. 4, to gutters g<1>, one or two of which are formed in the top or each electrode, the liquid escaping down grooves h in the side edges'of the electrodes or through pipes. (2) The bottoms b of the cells may be simultaneously raised or lowered by two cords or insulated wires i, Fig. 6, each passing around the movable bottoms and the supporting lugs j on the electrodes. One or both ends of each cord &c. are attached to the frame or to weights k. (3) India-rubber tubing, cord, or tape, or other compressible packing- material forms the ends of the cells; a continuous length may be zigzagged up and down between the electrodes. Similar material may be used for packing the movable bottoms. The upper edges of the electrodes may be bevelled or chamfered. The electrodes are supported by their lugs, or rest on collars on rods coated with insulation. According to Provisional Specification 12903/16, the tube at or near the bottom of each cell may serve as an outlet instead of an inlet; and according to both Provisional Specifications, the bottoms may be immovable and may be made of glass and clamped between the electrodes.

Title: Automatically operated vehicle restraint mechanism
IPC: G07F17/24
Filed: 1973-03-09
Abstract: 1469503 Retractable vehicle barrier P C D WARDLE A M CARVILL and F W PAGE 11 March 1974 [9 March 1973 26 Oct 1973] 11639/73 and 50050/73 Heading E1G [Also in Division G4] An automatically operated vehicle restraint mechanism for a kerbside parking bay 12-12 comprises sensing means 17 to sense the pressence of a vehicle, vehicle barrier posts 34, movable between an inoperative and an operative position in which they prevent removal of the vehicle from the parking bay, the sensing means being adapted to initiate movement of the posts in response to the presence of a vehicle, and a metering mechanism 19 to time the presence of a vehicle and initiate movement of the posts into the inoperative position in response to a signal applied to the metering mechanism. The posts are telescopic and are mounted on trollies 31, (31a) Fig. 4 (not shown) which are movable in a trough 16. The trollies are mounted by wheels 32 on guide rails 29, 30 and have brakes 37 that can cooperate with a continuous brake plate 38. A linear induction motor 33 is located adjacent rail 28 to drive each trolley, the motors are speed governed. Each trolley also has an .ultrasonic sensing device 36 which has a transmitter and a receiver. A reflector 39 transposes a beam in a right angle direction. The top of the trough has a series of hinged plates 41 each of which is slightly less than half the width of a post 34. Operation. When sensing element 17 detects a vehicle timing mechanism 19 is started and the drive motors 33 started to move the trollies towards each other. Sensing device 36 is also operative so that when the trolley reaches the extremity of a vehicle the trolley can be stopped and held in position by the brake. Air pump 35 is then operated so that the telescopic posts 34 are extended. Reverse movement of the trollies is initiated when coins or tokens are used in meter 19 to return it to zero. The meter may have two clocks one being for an excess period. If there are two clocks, then meter feeding is prevented by having the clocks linked in such a manner that if the first clock is returned to zero then a time delay is started so that if after the trollies have been returned to their initial positions the vehicle is not removed, the trollies are reactivated and any further time is recorded on the excess clock. Feeding without returning the first meter to zero merely activates the excess meter to record any further time. The parking bays may be at right angles to the pavement in which case the troughs are slightly larger than the bays. A further post, possibly on a trolley may be positioned on the side of the bay away from the pavement. Mechanism may also be provided so that if a vehicle overhangs another, the relevant trollies in the main bay moves the adjacent trolley out of the way so that it can be correctly positioned.

Title: Improvements relating to abrasive throwing machines
IPC: B24C5/06
Filed: 1934-04-18
Abstract: 441,466. Sand-blasting; centrifugal fans. BYRNE, E. L. W., 329, High Holborn, London.-(American Foundry Equipment Co/; 366, Madison Avenue, New York, U.S.A.) April 18, 1934, No. 11720. [Class 60] [See also Group XXVI] The invention comprises improvements in a machine for throwing abrasive material such as sand, filings, or shot at blasting velocity, in which a number of throwing vanes 2 rotate about a stationary control chamber c provided with an aperture o through which the abrasive is forcibly fed to the inner ends of the vanes by an impellor 22, the angular setting, extent, and shape of the aperture o determining the direction and extent of the stream of abrasive emerging at the periphery of the machine. In the construction shown, the machine comprises spaced rotary discs 1, 15 between which are substantially straight radial throwing vanes 2 with guard vanes 3 connected to them by ap x portions 4. The vanes are faced by removable wear shoes b having side walls 11, and held in place by set-screws 14. The chamber c which controls the discharge of abrasive comprises a tubular wall 30 rotatably mounted in a collar 33 and locked in adjusted angular position by hinged bolts 34, in order to allow the position of the discharge opening o to be adjusted to give the desired direction to the abrasive emerging from the periphery of the machine. The abrasive is fed by a pipe 17 to the inside of an impeller within the chamber c, comprising blades 22 attached to an end plate 21 secured to a plate 23 fixed to the rotary disc 1, so that the impellor rotates at the same speed as the throwing vanes. Alternatively, the impellor may be independently driven. The opening o in the wall of the control chamber, through which the abrasive is thrown by the impellor to the ends of the throwing-blades 2, may be of triangular shape and positioned so that the ends of the impellor blades pass from its apex to its base. This results in the abrasive being discharged first from the centre and then towards the margins of the blades 22 as they pass across the gradually widening opening, so that a substantially uniform discharge is obtained. Alternatively a biassed slot opening o<1>, Fig. 5, may be employed with the same object. Specifications 442,539 and 442,584 are referred to.

An apparatus to determine the benzole content of coal or coke oven gas comprises a low-pressure mercury vapour discharge lamp emitting substantially all its light at 2537A‹ through the heated transparent walls of a chamber containing the test gas on to a vacuum photo-electric cell having a quartz envelope. The walls may be double quartz windows separated by electric resistance elements and silicone rubber rings or they may be heated by passing hot gas between the hollows in the walls. Valves 65 and 72, Fig. 2, are connected in a bridge circuit so that differences between the anode currents may be detected by a microammeter 69. In operation, variable resistor 79 is adjusted so that a potential divider comprising resistors 77, 78 and 79 is balanced against resistors 70 and 71. Variable resistor 68 is adjusted until the anode current of valve 65 reaches a given value and variable resistor 74 adjusted to balance the anode currents of valves 65 and 72. Switch 75, 76 is then operated to connect the control grid of valve 72 to the cathode of photo-electric cell 12 and the difference between the anode currents of the valves is displayed at the meter 69. The primary winding of transformer 50 is supplied with a constant voltage through transformer 52, as is the primary winding of transformer 82, the secondary winding of which supplies lamp 11. The wall heaters 16 are supplied from a low voltage source 83. An alternative measuring circuit is shown in Fig. 3, wherein the tetrode 116 controls the current flowing through the lamp 11 by having its screen grid maintained at a stabilized potential by gas-filled voltage stabilizers 119, 120. The signal from photo-electric cell 12 is applied to the control grid of pentode 124 (which is connected to pentode 125 to form a differential amplifier) and potentiometers 118, 134 and 135 adjusted so that with maximum light falling on the cell the microammeter 138 is not deflected. The heaters 16 are connected to the low voltage secondary winding 105 of transformer 101 which includes a pilot light 107. The higher voltage secondary winding 106 is connected to a voltage-doubler rectifier circuit 108. To ensure starting of the lamp 11 one electrode is connected through capacitor 147 to one side of the winding 106.
