Title: Improvements relating to automatic dispensing nozzles
IPC: F16K21/00
Filed: 1964-07-09
Abstract: 1,073,142. Nozzles. DOVER CORPORATION. July 9, 1964 [July 19, 1963], No. 28428/64. Heading B2F. [Also in Division F2] A petrol pump nozzle having a main valve which can be latched into the open position until an orifice adjacent the nozzle is covered to increase a venturi-induced suction action, operative to unlatch the valve, is provided with timing means operable after a preset time to block the inlet from the orifice to effect the same unlatching operation even though the orifice may not be covered. The operator sets a timing device 11, Fig. 2 and raises the lever 15, which is held by a latch 75, thereby opening valve 13 to permit petrol to flow from the hose input 20 and the chamber 23 to the nozzle 14. Provided the orifice 41 is not below the fluid level in the car tank, air is drawn through tubes 40, 43, 47, Fig. 4 and chamber 39 by suction from the venturi tube 60, 61 due to the flow of petrol past the valve 13. At the expiry of the time to which the timer 11 is set, a cam 54 thereof operates valve 45 to shut off the tube 47 thereby increasing the suction in chamber 39. Diaphragm 17 is thereby moved upwards to raise the pin 36 so that a ball catch 33 is released, so freeing the plunger 29 carrying a fulcrum 27 for the lever 25. The downward pressure on the valve extension 25 due to spring 22, causes the fulcrum 27 to move downwards, so allowing valve 13 to close and shut off the supply of petrol. The suction in chamber 39 is thus terminated. When the lever is released from the latch 75 the plunger 29 and the fulcrum 27 are restored to the upper position, by the action of spring 32, in which position they are again held by the ball catch 33.

Abstract: 175,334. Lupascu, I. Oct. 7, 1920. Stationary-vessel wet-separating and washing apparatus.-Granular materials are separated in accordance with the size, density, or other variable quality of the individual grains by projecting the material to be separated into a fluid current from which the grains are dropped at different distances from their point of entry into the current. The apparatus shown comprises a box S containing liquid, through which a current of the same liquid is caused to flow from a tank T through an adjustable opening e. The material to be separated falls from a hopper Z into the current, and the various grades are dropped into compartments formed by partitions o, p, q in the bottom of the box. The bottom of the box may be sloping, as shown, or horizontal, and may extend to the side of the current, in order that the separated material may be continuously removed from the apparatus by elevators or other means during the separating process. The current of liquid may be horizontal, as shown, or oblique. In a modification, the current of liquid is projected into a separating-box filled with air or other gas. Any or all of the compartments for receiving the separated material may lead to a secondary separator, in which a further separation takes place in a current of liquid. The primary separation may, in this case, be effected in a current of air. Reference has been directed by the Comptroller to Specifications 1954/72, 17827/92, [Class 117, Sifting &c.], 164/93, 13072/95, 16166/95, 28642/12, [Class 117, Sifting &c.], 26418/13, and 134,856, [Class 117, Sifting &c.].

Abstract: 1,099,412. Lasers for producing scanning light beams. INTERNATIONAL BUSINESS MACHINES CORPORATION. July 6, 1965 [Aug. 5, 1964], No. 28507/65. Heading H1C. A device for producing a scanning light beam comprises a ruby or Nd in glass laser in which lasering action is prevented by polarization means and an ultrasonic wave traverses the active medium to render it in a predetermined birefringent state thereby allowing lasering in a filamentary portion of the active medium determined by the position of the wave. As shown in Fig. 1, a polarizer 22 transmits only horizontally polarized light and a flat ruby crystal 10 is cut to prefer a vertical polarization on light travelling towards the polarizer 22. A piezo-electric transducer 27 generates an ultrasonic wave which traverses the crystal, thereby altering its birefringence to prefer a horizontal polarization on light travelling towards polarizer 22; 28 denotes a waveabsorber. In Fig. 2 (not shown), two crossed polarizers (32, 33) are used, the optic axis of the ruby being parallel to the axis of the cavity. Two dimensional scanning is possible using two transducers (47, 49), Figs. 3 and 4 (not shown), or an ultrasonic wave from one transducer (56) may be reflected to traverse each of a stack of crystals in succession, Fig. 5 (not shown). If an Nd in glass active medium is used, Brewster angle windows may be provided at its ends.
