Title: Improvements in means for producing temperature control of a human body
IPC: A61F7/00
Filed: 1955-12-01
Abstract: 820,794. Heating and cooling chambers. KINDAL, R. M. Dec. 1, 1955 [Dec. 3, 1954; July 23, 1955], No. 34383/55. Class 81 (2). Apparatus for controlling the temperature of the human body includes a space for the patient, separated from the atmosphere and through which air flows, and means for controlling the velocity of the air flow, the temperature of the air and for supporting the patient so that the entire body area contacts the air flow. A permeable textile fabric support 3 supports the patient in a space formed by an arched hood divided transversely into removable transparent sectional covers 4. Air is driven by a fan 6, the speed of which is controllable past a cooling element 10 and heating elements (Fig. 2, not shown) and through a perforated plate 8 to the patient. After flowing round the patient the air is withdrawn by the fan 6 for recirculation. The temperature of the air is controlled in response to a rectal thermostat 26 which is connected by way of a selector 31 and an electronic relay 23 with relays 18, 19 in parallel, for a refrigerator motor and the heating elements respectively. Limiting thermostats 21, 22 are arranged in series with the relays 18, 19 respectively to prevent excessive cooling or heating. The arrangement is such that by movement of a wiper 32 of the selector 31 either (1) the rectal thermostat 26 and the selector 31 are disconnected and the heating elements operate alone, or (2) the rectal thermostat 26 is disconnected, the selector 31 is connected and the refrigerator operates alone, or (3) the rectal thermostat 26 and the selector 31 are connected and the heating elements and refrigerator operate alternately in order to maintain the patient at a constant temperature. The cooling element 10 is cooled directly by the refrigerator or by a cooling medium, e.g. an alcohol-water mixture, from a refrigerator.

Title: Improvements in or relating to coating iron or steel structures with metals
IPC: C23C22/68
Filed: 1935-12-11
Abstract: Iron or steel structures are treated at atmospheric temperature with a substantially neutral non-oxidizing liquid containing a compound of zinc, chromium, magnesium or other metal less noble than iron but not less noble than magnesium and another compound in the form of a salt of another metal capable of forming a complex salt with iron, to form a protective metallic coating. The liquid may be applied to the inner wall surface of a container by filling the container therewith or by introduction of a small quantity into the liquid to be stored in the container.  It may also be formed into a paste and applied by brushing or spraying: rust should not be removed prior to applications.  The liquid may also contain an electrolyte such as an alkali metal chloride.  The compounds employed may be zinc chloride or sulphate and potassium tartrate: acetates may also be used.  Clay or kieselguhr may be used to form the paste and sea water may be employed as the solute.  Ships, ships' tanks, steam boilers, pipe lines, buildings, bridges, masts, pillars and posts may be treated.

Abstract: 1535634 Reflex cameras FRANKE & HEIDECKE GmbH [trading as ROLLEI-WERKE FRANKE & HEIDECKE] 18 Aug 1977 [9 Sept 1976] 34726/77 Addition to 1446457 Heading G2A In a TTL reflex camera having mechanism for changing the diaphragm aperture from a maximum to a desired value determined by the photo-cell and the exposure setting, and in which a current pulse is emitted when the aperture reaches its desired value to stop the diaphragm mechanism, when signals representing the actual value and the desired value differ by a given amount, a current is produced in the magnetic brake to slow the diaphragm mechanism without stopping it. The signals representing actual and desired aperture values are fed to terminals 24, 25 of a circuit, Fig. 4, having differentiating circuits 26, 28, differential amplifier 30, comparator 29 and a current limiter 31. When the signal difference is below a given value, current flows through limiter 31 to a winding 20 of a magnetic brake, Figs. 2, 3 having a disc 15 rotated by the diaphragm mechanism and pivoted weights forming part of the magnetic circuit. The current causes the weights to press against the wall 19 at the housing to have braking effect but not to stop disc 15. When the signals are equal, a larger current flows from comparator 29, so that disc 15 is drawn into contact with the housing, stopping the mechanism.

Title: Improvements in or relating to control systems for automatically controlling the speed of a craft propelled by one or more engines
IPC: G05D1/06
Filed: 1945-12-24
Abstract: 618,954. Electric control systems. SPERRY GYROSCOPE CO., Inc. Dec. 24, 1945, No. 34907. Convention date, Dec. 29, 1944. [Class 40 (i)] [Also in Group XXXV] In a speed control system for an enginepropelled craft, the engine power regulator is automatically adjusted in response to an error signal corresponding to the difference between a signal dependent in magnitude and sign on the departure of craft speed from a predetermined value and a signal dependent in magnitude and sign on the departure of the power regulator setting from a predetermined value. In a system for controlling the speed of a multiple-engined aircraft, airspeed responsive means including a Pitot head 12, a differential pressure diaphragm 15, altitude compensating means 21, and temperature compensating means 19 adjust the position of the A.C. energized rotor of a selsyn transmitter 24, the stator 27 of which gives an output dependent in magnitude and sense on deviation from a desired airspeed preset by knob 28 adjusting the position of stator 27. A similar selsyn transmitter 31 has the position of its A.C. energized rotor 32 adjusted by the throttle 6 of one engine (Number 1) so that the output of its stator 34 is dependent in magnitude and sense on deviation of the throttle from a position, preset by knob 35 adjusting stator 34, corresponding to the desired airspeed. The outputs of the two selsyn transmitters, the ratio of which is adjustable by potentiometer 43, are combined differentially and control, through amplifier 45, the energization of one winding 40 of a squirrel-cage induction motor 38 adjusting throttle 6 to maintain the combined transmitter output zero and thereby restoring airspeed to the desired value. Damping is provided by injecting the output of a tachometer alternator 46, driven by motor 38, in phase opposition to the input of amplifier 45. Adjustment of throttles 9 and 10 of engines numbers 2 and 3 simultaneously with throttle 6 is effected through selsyn transmissions having a common transmitter 49 associated with throttle 6 and receivers 50, 51 associated with throttles 9 and 10 respectively. A.C. energized transmitter rotor 52 is coupled to throttle 6 and transmitter stator 55 is connected to receive stators 56 and 57. The outputs of receiver rotors 53 and 54, coupled to throttles 9 and 10, control, through amplifiers 58 and 61 the energization of windings 59 and 62 of induction motors driving throttles 9 and 10 into relative positions preset by knobs 64 and 65 adjusting stators 56 and 57. Damping is provided by tachometer alternators 60 and 63.

Title: A method and an installation in which a mixture of coal dust and water is atomised and the coal dust is burned
IPC: F23D1/00
Filed: 1969-07-14
Abstract: 1,223,369. Pulverulent fuel burners. SIEMENS A.G. 14 July, 1969 [13 July, 1968], No. 35417/69. Heading F4T. In order to atomize a mixture 2 of coal dust and water the mixture 2, is fed into a container 1 and caused to issue from a constricted outlet 5 of the container 1 at a pressure of several atmospheres, the mixture 2 being heated, just before it issues from the outlet 5, to a temperature just below the water vaporization temperature corresponding to the pressure produced upstream of the outlet 5, so that the water on expanding is vaporized immediately after issuing from the outlet 5 after which the coal dust is burned. As shown in Fig. 1, the container 1 is elongate and is surrounded by an electrical heating device 3 to heat the mixture 2 as it is fed along the container 1 to a closure wall 4 at one end of the container, which wall 4 is formed with a hole which is intersected by the longitudinal axis of the container 1 and constitutes the outlet 5. In Fig. 2 (not shown) the mixture 2 is heated by a flow of steam in a jacket (7) which flow is countercurrent to the flow of the mixture 2 as it moves along the container 1 to a closure wall (9), the outlet (10) of the container 1 being constituted by radial holes through the side of the container 1 adjacent the closure wall (10). The sudden expansion and vaporization of the water immediately downstream of the outlet causes great turbulence to thereby disperse the coal dust into a state suitable for burning, and this turbulence may be increased by a device for producing a spinning effect arranged in the container upstream of the outlet. The heat produced by the burning of the coal dust may be used to generate electricity through the intermediary of a steam turbine.
