Patent GB-993883-A (GB)
Title: Improvements in sterilisation autoclaves
IPC: A61L2/07
Filed: 1962-03-02
Abstract: 993,883. Sterilization autoclaves. ELECTROLUX. A.B. March 2, 1962 [March 4, 1961], No. 8130/62. Heading A5G. A sterilization autoclave comprises a sterilizing chamber 1, a steam generator 2, a water container 3 arranged over the generator and having condensing tubes 4 and 5, a three-way valve 6 with connections to the steam generator, to the bottom section of the sterilizing chamber and to the condensing tube 4, and a three-way valve 7 with connections to the steam generator, the upper section of the sterilizing chamber and to the condensing tube 5. Both the valves are operated by a common link mechanism 8 comprising a handle 9. The link mechanism is mechanically connected to an electric circuit breaker 10 connected in circuit with electrical heating elements 11 in the steam generator. The sterilizing chamber contains a compartment 12 in which the material to be sterilized is placed. Fig. 1 represents the arrangement of the autoclave when a sterilizing operation is in progress; Fig. 2 represents the autoclave arrangement when sterilization is not in progress. When sterilization is in progrses, the circuit breaker is closed so that the heating elements are functioning. The water in the steam generator is vaporized and steam is supplied to the sterilizing chamber. Ventilation takes place by means of a steam trap 13. When sterilization is stopped, by means of the handle 9, the current to the heating elements in the steam generator is cut off. The steam trap prevents the formation of a vacuum in the sterilizing chamber; as the autoclave cools, the steam trap is opened gradually to admit air and equalize the pressure. The advantages of the autoclave are that a correct amount of water is supplied to the steam generator through the condensing tube 5; in order to form a steam space in the steam generator when sterilization is to take place, the excess water flows through the valve 6 into the sterilizing chamber; the condensate from the walls of the sterilizing chamber is collected at the bottom to flow back to the steam generator, thereby removing the danger of the heating elements not being immersed in water; when sterilization is stopped, the water in the bottom of the chamber is pushed up into the water container through the condensing tube 4; and the material which has been sterilized, because of its own heat, becomes dry.

Title: Improvements in and relating to optical data processing systems
IPC: G11B7/12
Filed: 1966-02-25
Abstract: 1,143,195. Optical data processing. CONDUCTRON CORP. Feb. 25, 1966 [March 3, 1965], No. 8317/66. Heading G2J. In an optical data processing system in which information on a signal carrier such as a film 150, Fig. 4, is mathematically processed in an optical system 160 to produce an output image on a recording medium such as a film 170, the optical system 160 usually has an aperture corresponding to the film width and consequently is large and expensive for large formats, so to avoid this the beam is scanned across the widths of the films 150, 170. As shown, a frame F, which is longitudinally reciprocated by a motor 120 and eccentric 122, carries three pairs of mirrors 144, 146; 152, 154; and 166, 168, each mirror being at 45 degrees to the axis 180 of laser 110 and optical system 160. Fixed mirrors 142, 157, 165 suitably deflect the beam so that the beam from laser 110 is scanned across the width of film 150 and the processed beam synchronously scanned across film 170, both films 150, 170, being advanced longitudinally at a rate to ensure economic use of film. A shutter 126 is operated by lever 128 and pins 130, 132, to ensure that the beam only operates during motion in one direction and is cut-off during the reverse cycle. In a modification Fig. 5 (not shown), the frame M moves perpendicularly to the axis of the optical processing system 216 and the fixed mirrors are eliminated. In a further form Fig. 2 (not shown) each pair of mirrors (22, 24; 32, 34; 38, 40) forms a periscopic system rotatable about the common axis of the laser (20) and optical processing system (36).

Filed: 1946-03-19
Abstract: 609,619. Refrigerating. AKTIEBOLAGET ELEKTROLUX. March 19, 1946, No. 8440. Convention date, April 17, 1945. [Class 29] Absorption apparatus.-In a vapour expulsion unit for apparatus of the continuous cycle inert gas type a weak liquor stand pipe 17 forming a vent for the liquid heat exchanger 11 has a pocket-like lower extension 22 welded to the heated part of the flue tube 10 to effect expulsion of refrigerant and the liquid space of the stand pipe communicates with an auxiliary pump pipe 23 for defrosting. The base of the pocket may be thermally separated from the flue and, due to the assymmetrical application of heat, a circulation and renewal of liquid in the pocket is caused. The stand pipe 17 opens into the vapour pipe 16 from the boiler tube and a pump pipe 19 welded to the flue tube pumps weak liquor from the bottom of the main boiler tube 15 to the top of the stand pipe. The auxiliary pump tube 23 with opens by a bell-shaped mouth 30 into the stand pipe 17 above the pocket, and passes upwardly, through a larger pipe 25 welded to the flue 10, to the evaporator or the pressure equalizing vessel. The pipe 25 is closed at the bottom and connected by a flexible pipe 26 to the defrosting container 27. During normal operation vapour bubbles caught in the bell 30 pass up the pipe 23 and condense, increasing the concentration in the pipe. To defrost, the container 27 is tilted to transfer the liquid heat transfer medium to the warm pipe 25 causing vaporization in the pipe 23 to pump the liquid therein to the evaporator until the heat transfer medium distils back into the container 27.

Filed: 1961-03-09
Abstract: 920,305. Magnetic tape recorders; pause controls. REVERE CAMERA CO. March 9, 1961 [March 11, 1960], No. 8626/61. Class 40 (2). Capstan - powered pinch - roller engagement means comprises an eccentric roller 85, Fig. 2, mounted on the same shaft 80 as the pinch roller 36, the said shaft 80 being mounted on a plate 75 pivoted at 76 and biased by a spring 77 towards the capstan 35. Roller 85 carries a pin 88 which, when the machine is inoperative, is held by a crooked leaf-spring 89. The roller 85 engages the smaller diameter of capstan 35 below the larger diameter engageable by the pinch roller 36. When a forward drive is established for recording a playback, a bell-crank lever 107, 114, forming a toggle joint with an arm 106, is kicked into the position shown in Fig. 3 to permit roller 85 to be pressed under the influence of spring 77 against the capstan 35 which then rotates roller 85 so that pin 88 forces back the leaf-spring 89, and comes to rest against a surface 92 on the plate 75. In this position roller 85 is out of contact with the capstan 35 and the pinch roller 36 is therefore in engagement with the larger diameter of the capstan. A pause control is provided which comprises a second pair of toggle arms 135, 136, the arm 136 of which has an extension 137 movable through a mechanical linkage by a solenoid, which when operated moves the toggle arms to the position shown in Fig. 4 whereby plate 75 is rotated slightly against the tension of spring 77 to cause the pinch roller 36 to be slightly withdrawn from the capstan 35 and thereby to interrupt the drive of the tape.

Abstract: 764,759. Impulse transmitters. TELEFONAKTIEBOLAGET L. M. ERICSSON. March 24, 1955 [March 26, 1954], No. 8641/55. Class 40 (4). [Also in Group XXIV] In a telephone dial mechanism a speedegulator having a shaft 8 is driven through gears comprising balls 6, contained in a cage 7, and rollers 4, carried by pins 5 on a rotatable casting 3. The cage 7 is also fixed to the casting 3 which is rotated relative to a fixed casing 2 by means of a finger wheel 13. Rotation of the finger wheel clockwise rotates the rollers 4 and cage 7 clockwise without exerting pressure on the'balls 6 so that the shaft 8 is not driven. Rotation of the finger wheel anti-clockwise, however, compresses the balls 6 between the casing 2 and the rollers 4 and in consequence drives the speed regulator shaft 8. The rollers may be arranged to bear against the casing 2 while the caged balls bear against the shaft 8. The speed regulator comprises a disc 9 carrying weights 10 rotatable on studs 11 to engage a brake surface 12 formed on the casting 3. A cam surface 15 on the casting 3 is used to operate spring sets. The casting 3 may be made of nylon.
