Title: An improved sterilising autoclave
Inventor: RAWLINGS ALFRED FREDERICK
IPC: A61L2/07
Filed: 1963-05-23
Abstract: 1,088,953. Sterilising autoclave. DENT & HELLYER Ltd. Aug. 24, 1964 [May 23, 1963], No. 20581/63. Heading A5G. A sterilising autoclave comprises a sterilisation compartment provided with a charging opening to which a closure device may be fitted in a pressure-tight manner, a water tank, a water chamber arranged to receive water from said tank, thermostatically-conttrolled means for connecting the water chamber alternately to a water-heating compartment, to enable a predetermined quantity of water to be delivered to the water-heating compartment from the chamber, and to the tank, to enable water to flow from the tank for the purpose of replenishing the water chamber, a heater for heating the water delivered to the waterheating compartment and converting it. into steam, and a condenser for condensing the generated steam and returning it to said tank. The sterilisation compartment and the waterheating compartment may be one and the same compartment. As shown in the Figures 1 and 2, articles 27 to be sterilised are placed in sterilisation compartment 1, on shelf 28. Door 5 is locked (thus closing switch 24), switch 8 is opened and three-way cock 13 is positioned such that it connects pipe 14 to pipe 16 (i.e. water chamber 11 is connected to water tank 10). Switch 7 is opened and switch 19 is closed. On connecting the autoclave to the voltage supply source V by closing switch 8, the solenoid coil 18 is energised and moves the three-way cock 13 such that it connects pipe 14 to pipe 15. The contents of water-chamber 11 drain by gravity into compartment 2. On closing switch 7, immersion heater 6 is energised and the water in compartment 2 is converted into steam and passes into compartment 1 via pipe 3. Steam passes out of compartment 1 via pipe 20 to condenser 21 and the condensate is forced from outlet 22 into tank 10 by the steam pressure in compartment 1. Non-return valve 17 prevents water or steam flowing back along pipe 15 from compartment 2 to chamber 11. Switch 7 opens thermostatically at die -end of the sterilising cycle, i.e. when all the water in compartment 2 has been converted to steam. Switch 19 may be set to open before the end of the sterilising cycle so that solenoid coil 18 is de-energised and the three-way cock 13 returns to the position in which it connects pipe 14 to pipe 16, so that water can flow from tank 10 into chamber 11. The above cycle may then be repeated.

Title: Hydraulic shearing machine
Inventor: WHEELWRIGHT KENNETH ALBERT
IPC: B23D15/14
Filed: 1968-05-02
Abstract: 1,202,947. Shearing. HILL & GILBERT (HYDRAULIC DIVISION) Ltd. 1 May, 1969 [2 May, 1968], No. 20752/68. Heading B3W. An hydraulic shear in which the hydraulic fluid supply to the hydraulic cylinder and piston assembly 17 which moves shear jaw 18 about pivot 19 is controlled by an electrical solenoidoperated distribution valve 16 which is actuated by press-button control to interrupt the travel of the shear jaw 18. Solenoids (21) and (22) (Fig. 2, not shown) act on respective ends of the valve to cause the jaw 18 to be moved downwards and upwards respectively. When neither solenoid is actuated a spring-centred spool (not shown) urges the valve to a neutral condition in which oil is returned to the storage tank 13 and the jaw remains in the position it had reached before its travel was interrupted. If the arrangement is such that the operator must continually press the relevant button to keep the jaw moving a limit switch 30 actuated by the jaw 18 or a part movable therewith is provided for preventing the operator moving the jaw 18 too far in the downward direction. For automatic operation a further press button 25 is provided which brings limit switches 27, 28 into circuit to de-energize solenoids (22) and (21) and energize solenoids (21) and (22) respectively. The limit switches 27, 28 are actuated by the jaw 18 or a part movable therewith at the limits of its upward and downward movement respectively. The automatic control can be overidden during downward travel and reversed by the operator pressing button 29 which causes solenoid 21 to be de-energized and solenoid 22 to be energized. When the jaw operates limit switch 27 automatic working will start again. The stroke of the jaw 18 is variable by moving the switches 27, 28. Alternatively the speed of the stroke may be varied, while the stroke remains the same, by varying the supply of fuel to an engine driving a pump 12 moving oil from the tank 13 to valve 16.

Abstract: 501,520. Electrical musical instruments; converting currents. MIDGLEY, A. H., and MIDGLEY, A. M. July 31, 1937, No. 21310. [Class 88 (ii)] [Also in Group XXXV] A generator for producing electrostatically electric oscillations or an undulating potential to be translated into musical sound - waves, comprises two stationary electrodes constituting the plates of a condenser and means rotatable between the electrodes for periodically varying the specific inductive capacity or permittivity of a dielectric between the electrodes. In an instrument there may be twelve pairs of stationary insulating discs, each pair corresponding to a semitone note in the octave. Each insulating disc carries on its inner face eight sine-wave conducting rings, corresponding to different octaves of the scale note. Between each pair of discs rotates an insulating disc of phenolic condensation product with concentric rings of apertures or recesses, the passage of which varies the capacity periodically by varying the volume of insulating product or air between opposite parts of the electrodes. The intermediate discs are geared together in the ratio <12>#2. The circuits described are as in Specifications 493,320, 498,128, 498,130, and 499,771. In a modification, separate sets of discs are used for the two lower and the six higher octaves of a note, and only one member of the stationary pair has its rings undulated. The two sets of discs for one scale-note are combined as shown in Fig. 2, stationary electrodes 10, 3 having undulating rings, while stationary electrodes 11 have either plain rings or a complete surface. The dielectric discs 14, 14a have rings of upstanding sector-shaped parts, and are resiliently driven from a shaft 22 by adjustable gearing through a spring wire connection 26. Rings of apertures or cavities in the rotary discs may be filled with another dielectric such as celluloid. The metal rings may be formed by spraying the insulating foundation with metal and scribing the surface. The sine wave may be formed on one or both edges of a ring; according to the Provisional Specification, each sine wave form may be of half a wavelength only, separated by half a wavelength from its neighbour.
