Patent GB-226079-A (GB)
Abstract: 226,079. Reinhold, T. March 25, 1924. Photographic surveying-instruments; bore-hole clinometers.- An instrument for ascertaining. the extent and the direction of the inclination of the strata in the walls of a bore-hole comprises a device adapted to be lowered into the hole and provided with means for photographing simultaneously both the wall of the hole and the card of a compass contained within the instrument. The cas. ing 1 of the instrument is provided with chambers 4, 5 for the reception of pressure producing means, which operate piston rods 6, 7 adapted to exert pressure on packing rings 8, 9 in order to render watertight the section of the hole into which the instrument is lowered. Water for washing out this section is admitted through a passage 13 and fills the space around the casing 1 which has a watertight window 16. Within the casing is a camera 15 on. to which light from the wall of the hole is reflected by a mirror 17, the wall being illuminated by electric lamps adjacent the mirror. This mirror has a small cut-away part to allow direct access of rays from the compasscard 26 to the camera. In a modification the lamps are arranged above and below the window 16 so as to illuminate the wall directly. In a further modification the watertight window is immediately below the camera, the water entering the remainder of the casing, and the lamps are mounted on the camera.

Abstract: 1363992 Valves AIRCO Inc 19 May 1972 [20 May 1971] 23636/72 Heading F2V [Also in Division B3] A valve for mixing two different gases and for controlling the flow thereof, comprises two gas inlets 38 and 40 leading to a mixing chamber 48 and a gas outlet 42 leading from the chamber. In the state of the valve shown, Belleville washer 84 overcomes the pressure force which is generated by gas in chamber 48 and which acts on diaphragm 44. Accordingly, a plate 76 secured to the diaphragm acts to unseat the valves 62, 64 contained in each gas inlet, such valves being biased to their closed positions by springs 72. The plate is maintained in such position by the engagement of an armature 88 with a first permanent magnet 90. Upon the pressure in chamber 48 rising, the diaphragm moves against the washer 84 and so both inlet valves are seated by their respective springs. Armature 88 locks on to a second permanent magnet 92 with snap action. Each inlet contains a changeable throttle 60. The valve outlet 42 may be connected to a further mixing vessel (18, Fig. 1, not shown) in which case the outlet is connected to a tube (20) which extends within the vessel and terminates near the bottom of the vessel, the vessel outlet being located at the top of the vessel and provided with a pressure regulator 22.

Abstract: 844,351. Circuits employing bi-stable magnetic elements. WESTERN ELECTRIC CO. Inc. July 23, 1958 [July 31, 1957], No. 23715/58. Class 40 (9). [Also in Groups XIX and XXXV] The magnetic sheet element 1 (Fig. 1) made e.g. of manganese magnesium ferrite material having a rectangular hysteresis loop has four substantially equal flux legs A., B, C, D formed by apertures 2, 3 and 4 which are threaded respectively by an inhibiting pulse conductor 5, a conductor 6 for writing and reading pulses and an output conductor 7. In the absence of any coincident inhibiting pulse in 5, a writing pulse in lead 6 produces a direction of magnetization linking conductor 7 which represents a binary " 1." If there is a simultaneous inhibit pulse in 5 the storage of a binary " 1 " is prevented and its absence forms a binary " 0." Read out is by a pulse of opposite polarity in 6 which reverses the direction of flux linking 7 producing an output signal therein. A diode or similar device in 7 isolates the load 16 from any pulses produced in 7 by writing pulses in 6. The conductors may be deposited by evaporation or printing techniques. Fig. 3 shows a number of elements arranged in a "wordorganized" magnetic memory matrix and magnetically isolated from each other by slots or non-magnetic separation strips 21. The lead 6 threads all the magnetic elements in a row which store a " word " and are all selected at the same time while each inhibit conductor 5 threads a column. Pulsing of an element by an inhibit pulse alone does not prevent the element from responding correctly to a succeeding read pulse. None of the wires cross on the same side of the matrix so that printing or evaporation techniques can be employed in its manufacture. Collimated light from four sources may be used to produce the etched wiring which goes through the holes. Specification 760,307 is referred to.
