Abstract: 1,126,600. Valves. AGA A.B. 13 Jan., 1967 [15 Feb., 1966], No. 1863/67. Heading F2V. [Also in Division A5] Breathing apparatus comprises a multi-way diaphragm valve indicated generally at 2 connected to a mask 1 for enabling expiration to the atmosphere via non-return valve 9 and inspiration through conduit 3 of gas in a reservoir 4, an inhalation conduit 11 having a non-return valve 10, a regulator indicated generally at 12, and a tube 16 connected to the regulator having a fitting for coupling to a gas container. On inhalation, gas flows from the gas container via valves 15, 10, and 5 to the mask and on exhalation, exhaled gases pass via valves 5 and 9 to ambience. For purposes of artificial respiration, reservoir 4, which may be a rubber bag, is compressed to force the gas to be breathed into the lungs, the bag being re-filled with gas via non-return valve 10. The regulator comprises a housing 22 spanned by a diaphragm 13 having a lever 14 connected to plunger 30 of valve 15 abutting its central portion 29. A sub-pressure in conduit 11 causes the diaphragm 13 to be displaced inwardly of chamber 24 against the action of spring 35 so that the lever 14 depresses the plunger 30 to open valve 15. The regulator also comprises a relief valve 32, 33 which ensures that gas pressure in conduit 11 never rises above a predetermined maximum value.

Abstract: 1,151,021. Reciprocating generators. PURDY & McINTOSH (ELECTRONIC DEVELOPMENTS) Ltd. 8 Jan., 1968 [13 Jan., 1967], No. 2072/67. Heading H2A. A voltage generator operated by a pushbutton comprises a tubular member 1 of magnetic material, having a winding 2 wound on it and an operating rod 3 passing through it attached at one end to a spring-loaded button 4 and at the other end to permanent magnet 6 by spring 5. Normally, magnet 6 adheres or is close to the end of member 1 and when button 4 is pressed the force exerted by spring 5 increases until magnet 6 is propelled against stop 11 causing a voltage pulse to appear at terminals 13. The voltage pulse appearing when the button is released is suppressed by diode 12. Preferably, the end of member 1 adjacent the magnet is made concave to prevent the presence of foreign bodies influencing the operation. Operation of the generator may be inhibited by providing an additional winding either on member 1 or on a second core member, which winding when energized with D.C. will increase the attractive force between the magnet and core.

Title: Bistable magnetic data storage element
IPC: G06F3/00
Filed: 1971-01-15
Abstract: 1312434 Magnetic storage devices BAYER AG 15 Jan 1971 [23 Jan 1970] 2104/71 Heading H3B A bi-stable magnetic storage element comprises two magnetic cores 1, 2, Fig. 1, of different coercivities H 1  and H 2 , respectively, a magnetically controllable semi-conductor 5 such as a Hall effect device being used to sense the flux in an air gap 5 formed between core 2 and a yoke 3. A solenoid 6 can provide a field H such that H 2  < H < H 1 ; thus the solenoid can reverse the magnetization of core 2 but not that of core 1. When the magnetizations of the cores are opposed there is little flux through the semiconductor 5, but when the magnetizations are in the same direction the flux in the air gap is substantially larger. The semi-conductor is thus used to read the storage state of the element.
