Title: Ultra high vacuum ion gauge
IPC: H01J41/04
Filed: 1962-08-08
Abstract: 976,781. Ion gauges. GEOPHYSICS CORPORATION OF AMERICA. Aug. 8, 1962, No. 30325/62. Heading H1D. An ultra high vacuum ion gauge includes a source of electrons 20, an anode 32 for forming the electrons into a beam 22 directed towards trap means 36 for receiving the electrons, the trap means being arranged to absorb most of the X-rays 48 produced by the electrons, and a collector 34 for receiving ions produced by the electrons before reaching the trap means. The electron source may be a hot filament or a radio-active source which will give off sufficient electrons to ionize the gases within the gauge. A longitudinal magnetic H may be provided to focus the beam. The collector electrode 34 is circular and is positioned so that no primary or secondary X-rays produced within the device can strike it. Alternatively, the ions produced may be accelerated by potentials applied to grids provided adjacent the electron beam to a secondary electron emissive surface, the secondary electrons from which are amplified by an electron multiplier.

Abstract: 446,419. Elastic - fluid turbines. MAVOR & COULSON, Ltd., and MAVOR, J. B., 47, Broad Street, Mile-End, Glasgow. Oct. 24, 1934, No. 30460. [Class 110 (iii)] [See also Group XXX] In compressed air turbine-driven beltconveyers a brake is released by compressed air in the act of turning on the air for the turbine. Fig. 1 shows a turbine rotor A the shaft B of which carries a multiple-plate friction brake 7 which is made effective by the pressure of a spring 4 acting through a rocking arm 6. The spring 4 bears on a piston 3 moving in a cylinder 2, to which air is admitted to compress the spring 4 and release the brake 7 through a piston rod 5 and the arm 6. Fig. 4 shows a rotary hand cock C with a barrel 8, provided with two opposite openings 9, depicted in the position in which air is cut off both from the turbine and from the pipe 12 leading to the cylinder 2. An adjustable escape passage 13 is in this position connected by a byepass to the pipe 12, thus allowing the spring 4 to expand without back pressure on the piston 3. On turning the barrel 8 clockwise the passage 13 is first cut off air is then admitted to the cylinder 2 to release the brake 7, and afterwards to the turbine casing F, and in stopping air is cut off from the turbine before it is cut off from the cylinder 2. An adjustable air-release 15 is provided in the cylinder 2 to regulate the speed of the piston 3. The cylinder 2 may be disposed laterally of the shaft B, as shown, or in line therewith, the piston-rod 5 then operating the brake 7 through the agency of a yoke. The brake 7 may be mounted on any rotating part of the conveyer. Specifications 263,540, [Class 110 (ii)], and 350,799 are referred to.

Title: Improvements relating to electronic computer checking circuits
IPC: G06F11/10
Filed: 1956-10-11
Abstract: 838,301. Check symbols, calculating. INTERNATIONAL BUSINESS MACHINES CORPORATION. Oct. 11, 1956 [Oct. 14, 1955], No. 30949/56. Class 106 (1). An electronic computer comprises means for registering a digital data word and its indicator and means for effecting a modification of the registered indicator consequential to a modification of the registered data word, where the " indicator " of a digital data word is defined as the complement on 3 of that number which is congruent (mod. 4) to the number of 1-bits in the word. The apparatus actually described comprises two circuits, "Register 1 bit inventory computer " and " Register 2 bit inventory computer," Fig. 1, which are used in association with two registers 1 and 2 forming part of a known computer. Once a word is in digit positions DP1-DP16 and its indicator is in position DP 17, the word can gain or lose bits as the result of either a left or right shift, or a sign change, or an exponent change or as the result of a rounding operation. All gains and losses in these ways are totalled (individually) by the bit inventory computers, which are similar to each other, and if there is a net loss the original indicator is increased (mod. 4) by the number (mod. 4) of bits lost, and if there is a net gain the original indicator is increased (mod. 4) by the complement on four of the number (mod. 4) of bits gained. The arithmetic, storage and checking units employed are similar to those described in Specifications 719,418, 721,180, 790,323, 804,809, 804,810, 807,882 and 815,751, all of which are referred to.

As shown, Fig. 1, a mask, preferably of kraft paper, has a nose strip 17 of wire, or strip metal or plastics material, inlets 26 with filters (not shown) and an outlet 30 to an exhaust line 34 which may be connected to negative pressure inducing means carried on the person and comprising a casing 45 housing an exhaust fan, fluid pressure motor and a cylinder of gas, e.g. CO 2   or an electrically driven fan (not shown). Alternatively, the line 34 may be connected to an independent source of negative pressure. In another embodiment, Fig. 11, air or oxygen is supplied through a pipe 70, in which a one-way stop valve 75 may be located, which passes through an exhaust pipe 71. A reinforcement 25 is adhesively secured to the mask in embodiments in which negative or positive pressure is present within the mask. In an embodiment for use with positive pressure, Fig. 9, air or oxygen is supplied through a pipe 134 and exhalation takes place through outlets 65 of sufficient area to allow exhaust gases to pass out before such increase in pressure within the mask as would cause leakage around the edges of the mask. Filters 66 may be formed of foam rubber or urethane, glass fibre, flannel or gauze. In an embodiment for use with no pressure differential between the mask and atmosphere, Fig. 12, the reinforcement 25 is omitted and inhalation and exhalation take place through one large opening 80 with a filter 81. All embodiments have attachment portions 14, 19 to which a harness 23, 24 is secured.

Void [Abridged as open to inspection under Sect. 91 of the Acts, May 17, 1935]. [Class 40 (i)] [See also Group XIX] An electric signalling system comprises a cash register K, Fig. 10, connected to a distant indicator F, and a loud-speaker H1 or other telephone receiver H2 situated adjacent the indicator and connected to a microphone M in the neighbourhood of the cash register. The distant indicators are controlled by switches closed by the keys, or by the totalizer wheels or indicator drums of the cash register. Transmission from the totalizer wheels is effected by cams 16, Fig. 5, connected to the wheels by nested sleeves and each adapted to close a selected one of a series of contacts 17. Transmission from each indicator drum is effected by a brush carried by the drum and co-operating with a series of angularly-spaced stationary contacts. One type of distant indicator is shown in Figs. 2 and 3 and comprises denominational indicating segments 4 carried by counterweighted levers 2 and visible through a reading aperture 5 in the casing. The levers are actuated to differentially position the segments by magnets S selectively energized by the transmission means, the selected magnet attracting an iron core S1 slidable in a non-magnetic tube and provided with a hook S2 for engagement with the underside of the lever 2. A second type of distant indicator comprises a series of denominational indicating drums 12, Fig. 4, visible through a reading aperture 13 and each provided with a permanent magnet or iron core P.
