Title: Breathing apparatus for supplying a pair of gases in adjustable proportion
IPC: A62B7/14
Filed: 1966-11-10
Abstract: 1,104,640. Respiratory apparatus. AGA. AKTIEBOLAG. 10 Nov., 1966 [19 Jan., 1966], No. 50371/66. Heading A5T. Apparatus for supplying to a patient two gases (e.g. oxygen or air and nitrogen monoxide), in adjustable proportion but at a substantially constant rate, comprises a first conduit 1 leading to a mixing chamber 4 and including a first pressure regulator 6, a second conduit 2 leading to the mixing chamber 4 and including a second pressure regulator 58, an adjustable throttling device 23 in the first conduit, and a conduit 70 connecting the inlet 25 of the throttling device to the membrane of the second pressure regulator 58. The arrangement is such that an adjustment of the throttling device 23 to vary the rate of flow of a first gas through the conduit 1 creates a pressure change at the inlet 25, which provides an opposite variation in the rate of flow of the second gas through the conduit 2. As shown, the apparatus also includes a snap action on-off valve 16 controlled by the pressure in a conduit 5 leading to the patient, a rubber bag 37 which acts as a reservoir and which may be squeezed to provide artificial respiration to the patient, a valve arrangement 38 which may be held open by a knob 47, and inspiration and expiration valves 53, 57. A vane moving on a pivot 35 provides an indication of the proportions of the gases in the mixture.

Abstract: 1,015,900. Refrigerators. GENERAL ELECTRIC CO. Ltd. Nov. 17, 1964 [Dec. 20, 1963], No. 50409/63. Heading F4H. In a refrigerator having a chiller tray 3 slidably mounted beneath the evaporator 1, a spacer device 5 may be clipped to tray 3 in either a first position in which it spaces the tray from the rear wall of the cabinet or a second position in which it allows-the tray to abut said rear wall. The device 5 comprises a U-shaped clip 6 one limb of which has an extension 10 formed with a projection 11 near its free end. With the device 5 in the position shown the free end of limb 10 is spaced from the rear wall of tray 3 so that when the latter is pushed into the cabinet limb 10 engages a rib 12 on the rear wall of the cabinet and the tray is spaced from said rear wall to allow air to pass through the space. When the device is clipped with the limb 10 inside the tray the latter is free to contact rib 12 (Fig. 2, not shown).

Abstract: 1428355 Data recording system; workman's times recording INTERNATIONAL TIME RECORDING CO Ltd 2 Feb 1973 [4 Nov 1971] 51397/71 Headings G4T and G4M In a system for recording data (e.g. workman's times), pre-recorded information (e.g. a workman's identity) is read from a record (time) card and simultaneously the data in alphanumeric form is printed on the card. As shown, reading of a punched region of a time card 1 is effected by silicon voltaic cells 14 responsive to light emitted by gallium arsenide phosphide diodes or an electroluminescent panel 13. Insertion of the card in a guide 26 trips a microswitch 10 to energize the reader and to also propel a print hammer 7 towards time wheels 9. The position of the card guide/reader/microswitch assembly is adjustable so that the time is printed in the appropriate region of the card, Fig. 1 (not shown). The recorded time and the data read from the card are fed to a store, Fig. 3 (not shown). Several time recorder/store combinations may be provided and scanned by a single interrogation unit, which enables any store holding data to transfer same to a punched or magnetic tape recorder.
