IPC: A47L15/42
Filed: 1956-10-31
Abstract: 798,274. Dishwashing machines. TOLEDO SCALE CO. Oct. 31, 1956, No. 33183/56. Class 138(1). A dishwashing machine with pivoted hoods extending over the washing and rinsing spaces is provided with safety means whereby if the hoods are opened during operation the machine stops working. Alternatively, or in addition, a lock is operated when the machine is started so that the hoods cannot be opened during operation. The machine has hoods 3 pivoted on brackets 18 and a switch handle 10 is provided to start the cycle. A conventional sequence timer controls the rinsing and washing cycles and the cycle is stopped if the hoods are opened. To this end each hood carries a cam, the cams 27, 28 being arranged side by side at one pivot point, and each having a flat portion on the circumference. Both flats are adjacent when the hoods are closed, but if one or both hoods are raised, the appropriate cam opens a safety switch 15 in series with the timer " hold on" contacts and breaks the operating circuit. In a modification, Figs. 7 and 8, the cams are arranged on concentric sleeves 21a, 22a working in a stationary bush, and each sleeve and the bush have radial holes which are in alignment when both hoods are closed. A solenoid 32 is arranged to move a pin 33 into these holes when the machine is operated and thus the hoods are locked in a closed position. Fixed rinsing sprays 8 are arranged at the top and bottom of the washing space, and rotatable rinsing sprays 9 are provided to feed fresh hot water to rinse and sterilize the dishes.

Title: Treatment of electrically insulating materials subjected to ionising radiation and apparatus for measuring such radiation
Inventor: COLEMAN JOHN H
IPC: B01J19/08
Filed: 1953-12-08
Abstract: 735,847. Insulation; semiconductor materials. RADIATION RESEARCH CORPORATION. Dec. 8, 1953, No. 34062/53. Drawings to Specification. Classes 36 and 37. [Also in Groups XL (a) and XL (b)] The resistivity characteristics of insulating material under ionizing radiation are improved by subjecting the material to a dose of radiation substantially in excess of that required to raise the conductivity of the material to a value that does not increase thereafter. This large dose of radiation has the effect of reducing the conductivity of the insulating material to a value which may be less than that of the material prior to exposure to any radiation. Removal of the radiation source causes the conductivity of the material to return to the value it had prior to exposure, and any subsequent exposure causes the material to acquire at once the conductivity corresponding to that which obtained just prior to the removal of the original radiation. Polystyrene, mica, amber and polymonochlorotrifluoroethylene reinforced with fibre glass may be treated in this manner and small quantities of materials such as antioxidants added to the plastic materials may result in additional improvement in the conductivity. Insulating material treated in this manner may be employed in electric cables, especially coaxial cables.

Abstract: 867,383. Air conditioning apparatus. AMERICAN AIR FILTER CO. Inc. Oct. 24, 1958 [Jan. 6, 1958], No. 34069/58. Class 137. An air conditioning apparatus comprises a cabinet with an air inlet and a damper for regulating the proportion of room air to outdoor air induced into the apparatus by a blower, an adjustable by-pass damper to control the air flow either through a heat exchanger or through a by-pass chamber 9 an air outlet to the room, the heat exchanger being positioned between the inlet and outlet with its lower edge adjacent a rear wall of the cabinet and its upstream face extending upwardly and forwardly across the cabinet so that its upward forward edge forms the rear boundary of the bypass chamber. As shown, dampers 38 and 34 are mounted for rotation on shafts 40 and 36 which are secured to vertical partitions and these dampers control the amount of room air and outdoor air which enters via inlets 15 and 12. A passageway 42 incorporating a removable filter 44 supported in frame 96, connects the lower centre section of the cabinet with the upper section containing the heat exchanger 50 and a by pass damper 52 which extends transversely between partitions and is pivotally attached to a shaft 84. The blower consists of a series of laterally spaced fans 46 located in the upper section of the cabinet with the air outlet 18. With the damper 52 in the by pass position, (Fig. 10) air flow through the heat exchanger is prevented by flexible strips 66 which contact the members 72, 74, and the blades 68 and 70 which contact ledges 78 and 80, while the trough face 64 of the damper also deflects the air away from the heat exchanger. With the damper in the position shown in Fig. 2, air passes through the heat exchanger, the strips 66 then sealing against members 72 and 76. The conditioned air is directed into the annular inlets 49 of the fan housings 48 by means of oppositely disposed vanes 92 and 94 and then passes into the room via outlet 18. A drip pan 90 situated under the heat exchanger and attached to frame 96 directs any condensate into a receiver which is releasably connected to the drip pan. The damper movements may be automatically controlled according to the room temperature registered by a thermostat which then operates a pneumatic system.

Filed: 1971-07-21
Abstract: 1324203 Trigger circuit TESLA NARODNI PODNIK 21 July 1971 [28 July 1970] 34212/71 Heading H3T An electrical circuit divides the pulse frequency at its input to give narrow pulses at its output which may be used to trigger a timebase and comprises an emitter follower 4 whose base is connected to the slider of a potentiometer 11 between voltage supply lines and whose emitter is connected via a resistor 5 to a tunnel diode 13 and the input of an amplifier (such as transistor 6) whose output is connected via a primary of a differentiating transformer 7 and parallel connected resistor 9 and capacitor 8 to a supply line, a positive feedback resistor 10 being connected to one end of the primary and the circuit input. The circuit oscillates with a period determined by the parallel connected resistor and capacitor and the setting of potentiometer 11 which alters the frequency of oscillation by changing the bias on tunnel diode 13. A capacitor 3 stops the feedback signals from effectively being quenched. If by-passed by a switch 12 the low output impedance of an amplifier 2 stops the oscillations and a pulse is produced at the transformer secondary for each pulse in. Otherwise the circuit divides the frequency of the input pulses. A further input signal may be added via an additional transistor 14 which acts as a grounded base amplifier for signals at terminal 21. Another transistor may be connected between the capacitor 3 and the base of transistor 4 to produce a Darlington connected pair of transistors giving a high input impedance to the circuit.

Filed: 1973-07-19
Abstract: 1444592 Memory input arrangements INTERNATIONAL COMPUTERS Ltd 19 June 1974 [19 July 1973] 34428/73 Heading G4C Multi-word blocks in a memory 200 are individually addressable to allow writing to all the words of an addressed block in parallel, and consecutive words each accompanied by the same block address are collected from a stream of input words to be written in the memory, the collected words being transferred in parallel to the memory only when a change of block address occurs in the input stream. Input words are supplied, e.g. from a processor, over a bus 11 and the corresponding word addresses are supplied on a bus 14, each block address 25 being compared 28 with the block address of a preceding word stored in a register 13. A match output 79 from comparator 28 enables gates 37-40 so that the output of a decoder 32, which receives the word address bits 23, 24, sets a corresponding indicator 46 and gates the input word on bus 11 into the appropriate word section of a register 10 to accumulate consecutive words from the same block. When comparator 28 produces a mismatch output 81 indicating a change of block address, the contents of block register 10, block address register 13 and indicators 46 are transferred to buffer registers 16, 17, 85 respectively, occupied word locations of buffer 16, as determined by indicator buffer 85 being subsequently written into memory 200 at the block address specified by buffer 17. The mismatch output of comparator 28, after delay 83, 84, resets indicators 46, gates the new block address into register 13, and sets an indicator 46 appropriate to the new word being gated into the register 10 from bus 11. The system may be used for writing updated data from a fast access, low capacity slave store into a larger capacity, slower access memory 200, the arrangement reducing the number of accesses to memory 200 that have to be made. In a system comprising more than one processor, a request for a block may be passed over bus 14 to the memory controls of the other processors, any comparator which produces a match output gating the recently updated block from register 10 to bus 105. The system may also be extended for byte organization rather than word organization by including a byte address decoder 110 and corresponding indicators and gates.
