Title: Improvements in artificial respiration apparatus
IPC: A61M16/00
Filed: 1954-10-29
Abstract: 802,141. Respiratory appliances. PATRICK, D. A. Oct. 31, 1955 [Oct. 29, 1954], No. 31388/54. Class 81 (2). Portable respiratory apparatus for connection to a cuirass applied to a patient's chest comprises a constant-speed electric motor 22, Fig. 1, driving, through stopped pulley gearing 58, 60, a gear-box 24, and a rotary disc 66 and crank pin 56, an oscillating-cylinder air pump 38 connected by a flexible tube 24 to a valve box 76 connected by another flexible tube to the cuirass, and a battery-operated warning lamp and buzzer to indicate stoppage of the pump or rupture of the pipe connection between the valve box and the cuirass. The valve box, which may be of the kind described in Specification 802,142, includes two adjustable valves, one for controlling the admission of atmospheric air into the box and the other the discharge of air from the box. The warning lamp and the buzzer, together with a pressure gauge connected to the valve box, are disposed on the top of a sheet-metal or plastic casing enclosing a chassis 16 resiliently supported on a rigid base mounted on castors and to which the components of the apparatus are attached. The warning lamp and the buzzer are arranged in parallel with a dry battery 28 in a circuit including a switch having normally open contact arms 134, 136, Fig. 6, mounted upon a chamber 30 having a spring-loaded flexible diaphragm 122 which supports a post 128 carrying an adjustable screw 132. The interior of the chamber communicates with the atmosphere through a calibrated orifice plate 116 and through a spring-loaded non-return valve 112 and a flexible pipe 104 with the pump cylinder. When the pump is working the sub-atmospheric pressure maintained in the chamber is sufficient to hold the screw 132 below the switch arm 134, but failure of the pump or rupture of the pipe between the valve box 76 and the cuirass results in the pressure in the chamber rising so that the screw closes the arm 134 on the arm 136 thus completing the circuit through the warning lamp and the buzzer. By duplicating the pipe 74 and the valve box 76 the apparatus may be used on two patients simultaneously. A handle 84 is provided to permit manual operation of the pump in the event of failure of the electric motor 22.

IPC: G05D23/22
Filed: 1963-08-12
Abstract: 1,019,182. Measuring electrically. FOSTER INSTRUMENT CO. Ltd. Aug. 6, 1964 [Aug. 12, 1963], No. 31730/63. Heading G1N. [Also in Division G3] In a fail-safe arrangement for a temperature measuring and controlling apparatus, a resistance 4, approximately equal to the parallel resistance of measuring thermocouple 1 and galvanometer 2, is connected as shown. A transistor 3, having its base connected to the junction of thermocouple 1, meter 2, and resistance 4, is supplied between its emitter and collector with A.C. from a source 5; however, during normal operation, transistor 3 is never conductive, and the inertia of meter 2 renders it unresponsive to the small A. C. current which flows through it. Rupture of the thermocouple-meter circuit increases the base-emitter resistance of transistor 3, which now conducts during alternate half-cycles. This produces an asymmetrical current in meter 2, which causes full-scale deflection of the meter needle, and may reduce or arrest the heat supply to the controlled apparatus, e.g. a furnace.

Abstract: 784,371. Ophthalmoscopes. DUDRAGNE, R. A. Nov. 9, 1955 [Nov. 15, 1954], No. 32025/55.. Class 97(1) In an ophthalmoscope, an observing optical system is located on the opposite side of the optical axis of a photographic system to an illuminating system and, the latter comprises a low intensity source for continuous illumination of the fundus and a gas discharge tube capable 'of giving a photographic flash exposure. The translocation of the illuminating system enables the straight line between the operator's eye Oo and the patient's eye Op to be kept free from any obstruction. As shown, incandescent filament lamp S1 and gas discharge lamp S2, having diaphragms DS1 and DS2 respectively, are in conjugate positions with respect to lens L3 and diaphragms DS2 and Dp are in conjugate positions with respect to lens L4. Lens L1 forms an image of the fundus which is projected by lens L2 on to the film F or reflected by mirrors Me, Mv for observation. Although only part of the fundus is illuminated when the apparatus is held stationary, practically the whole of it can be illuminated on rotating the apparatus through an angle of 210 degrees about the axis OpF. In another form, prism P is located in front of lens L1, which is of sphero-parabolic form, and the prism is so near to the patient's eye that an unobstructed view of the eye is necessary to avoid injury. The light from the incandescent lamp is reflected by a half-silvered plate into an optical system consisting of four achromatic doublets and the light from the discharge tube is transmitted by the plate into the system.
