Title: Improvements in pressure gauge testing equipment
Inventor: GRANT CHARLES ROBERT ARCHIBALD
IPC: G01L27/00
Filed: 1952-08-13
Abstract: 744,136. Testing pressure gauges. PRESSURE GAUGES, Ltd. Oct. 1, 1953 [Aug. 13, 1952], No. 20380/52. Class 106 (2). A pressure amplifier for increasing the range of a pressure gauge testing equipment coinprises a loadable plunger 7 in a cylinder 2 containing a hydraulic fluid, a fluid supply reservoir 4, and a pump 3 by which a pressure can be built up in the hydraulic system until it balances the weight 9 on the plunger 7 when, if the gauge 38 is correctly calibrated, the reading on the gauge will correspond to the effective loading of the weights 9. The pressure amplifier 5 is introduced into the system between the gauge 38 and the piston and cylinder unit 2 and comprises a differential piston having its smaller diameter 32 nearest the gauge 38, and a control valve 37 adapted to connect both sides of the differential piston together when required. The pistons 31 and 32 of the differential piston are formed as separate pistons that abut against one another in operation, thus avoiding accurate coaxial machining of the cylinders. To measure a low pressure, valves 21 and 37 are opened and the pump handle 23 is rotated to withdraw the pump piston to fill the pump cylinder. Pistons 31 and 32 will fall under gravity during this operation. Valve 21 is then closed and the pump handle 23 rotated until the pressure generated lifts the piston 7 and the weights 9. The fluid pressure throughout the whole system is then uniform and the gauge 38 should indicate this pressure. To test the pressure gauge 38 for higher ranges than can be dealt with by the weights 9, valves 21 and 37 are closed before the pump handle 23 is rotated to create a pressure. The pressure acting below the piston 31 will cause it and piston 32 to rise to compress the liquid trapped above the piston 32. Since the cross-sectional area of piston 32 is less than that of piston 31 the pressure applied to the pressure gauge is greater than that generated by the weights 9 in the cylinder 2.

Title: Improvements relating to x-ray apparatus
IPC: G21K1/04
Filed: 1959-06-15
Abstract: 855,508. X-ray apparatus. PICKER X-RAY CORPORATION WAIFE MANUFACTURING DIVISION Inc. June 15, 1959 [Feb. 13, 1959], No. 20416/59. Class 98(1) An X-ray apparatus has a diaphragm for controlling the X-ray beam movably mounted with respect to a table so that the diaphragm can be positioned above the table or facing its underside, together with control means for adjusting the diaphragm mechanism, and means for coupling the said mechanism and control means to the table so that the control means can be operated from a distance. In Fig. 1 the apparatus is set up above the tilt table 12, the X-ray tube 10 being rotatably supported in a collar 15 connected to a telescoping and rotatable arm carried by a carriage 18 vertically movable on a column 20. Column 20 is rotatable and also movable along the length of the table. Below the table is a photographic plate 14. The collimator or diaphragm member 21 is mounted below the X-ray tube and structurally united with it. The collimator housing 22 has end openings 23, 24. Within the housing is a supporting frame 26, and two sets of adjustable diaphragms. One pair of diaphragms 28, 28a, associated with opening 24, are mounted on levers 32, 34, the ends of which curve inwardly and are pivotally connected as at 36 to frame 26. At the same end of housing 22 is a second pair of diaphragms 28b, 28c, moving at right-angles to the first pair, and similarly mounted on levers 38, 40 pivoted to frame 26. Associated with the opposite opening 23 are a pair of diaphragms 30, 30a, mounted on levers 44, 46 pivoted to frame 26, and a crossing pair 30c, 30d on similar levers 50, 52. Each of the levers 32, 34, 44, 46 carries a gear wheel, respectively 58, 58a, 58b, 58c, which all intermesh, and are actuated by a further gear wheel on lever 44 meshed with a pinion operated from outside the housing. Thus a single control wheel 63 will operate all four of these diaphragms, in accordance with suitable scale-markings on the housing. A similar arrangement is provided for operating the other four diaphragms from another control wheel on the housing. When, for fluorographic work, the X-ray tube and collimator unit is utilized facing the underside of the table, which is tilted to a generally vertical position (Fig. 2), it co-operates with a framework 75 attached to bars 78 on the table. The framework has V-shaped slots 84, into which enter lugs 86 on the collimator housing, the latter being held in position by automatically locking retaining means. On pulling a handle 98 upwards, these retaining means are released, so that the collimator and X-ray unit may be detached from the framework and table. The framework has a pair of forked elements mounted on it, into which fit pins on the two control wheels. Cables connect these forks to operating levers 104, 104a on the table 12, so that the diaphragm settings can be remote-controlled from the table.

Abstract: 904,746. Magnetic recording &c. apparatus. NATIONAL CASH REGISTER CO. June 7, 1961 [June 30, 1960], No. 20530/61. Class 40 (2). [Also in Group XIX] A continuous cyclic data storage system comprises a plurality of transducers each adapted to trace helical or spiral path on a recording surface. As described, a rotatable data storage drum 10 is driven by a motor 14 and has surface sections 18, 22 adapted for co-operation with respective transducers 20, 24 which are supported for transverse rectilinear movement in upwards and downwards directions and in antiphase, the transducers being effective alternately, each during its upward motion only. The downward movement of the transducers 20, 24 is faster than the upward movement, thereby providing a time interval for the attainment of a uniform speed. During their upward movement, the transducers 20, 24 successively trace helical tracks 40, 42 on the drum sections 18, 22. The drum 10 is driven by a motor 14 which also drives, via reduction gearing 36, a shaft 34 carrying cams 26, 30 to control the movement of the transducers 20, 24, the shaft 34 also carrying a commutator 44 to produce signals which control switching between the transducers 20, 24 in conjunction with timing signals read by a transducer 204 from tracks on an end surface of the drum. Each transducer 20, 24 includes a read head 80, 84 and a write head 82, 86, each write head being spaced apart by one word distance from the corresponding read head and a delay is produced by spaced record and read heads in a transducer 77a co-operating with a track 77t on an end face of the drum to cause switching between the write heads to take place one word period after switching between the read heads. The cams 26, 30 are shaped as shown in Fig. 7 and co-operate with followers 136, 138 connected to vertical shafts 28, 32 which carry the transducers 20, 24. The shafts 28, 32 carry arms 140, 142 co-operating in fixed slots 141, 143 to maintain alignment of the cam followers with the cams. The transducers 20, 24 are mounted on blocks 160, 162 which slide on vertical rods 170, 171 rotational movement of the transducers being inhibited by arms 172, 173 fixed to the blocks 160, 162 and co-operating with vertical edges 176, 177. Modifications.-The data storage tracks scanned by the heads 20, 24 may be interlaced. Three or more transducers may be employed. The drum may be replaced by a tape, disc or belt. The data may be permanently recorded.

Abstract: 1276861 Sampling liquids; automatic analysis AUTOMATED ANALYZERS Inc 6 May 1969 [6 May 1968] 20539/69 Heading B1X A predetermined volume of liquid sample is obtained for analysis by a method comprising providing a pad, for example pad 56 on a tape 50, the pad being of predetermined volume and of a material of predetermined absorption characteristic, and saturating the pad with sample by a method including contacting the pad with a means for adjusting the liquid sample contents of the pad just to saturation. An excess of liquid may be added to the pad (Figs. 2, 4 not shown) and surplus liquid removed by touching a capillary to the pad. Alternatively liquid may be introduced to the pad from a liquid containing capillary or by means of a wick having one end in a container of liquid sample, when, it is stated, liquid uptake by the pad ceases when the pad is just saturated (Figs. 1 to 3 not shown). The pad may be of cotton, wool, rayon, nylon, cellulose, polyethylene, porous ceramic. In the embodiment shown, capillaries 110 holding liquid samples are mounted in holders (102) which are pivotably held at the periphery of rotatable plate 100. Rotation of the plate causes tipping of one of the capillaries into a vertical position, when a piston member (132) (Fig. 6 not shown) is applied to one end of the capillary to bring its other end into contact with the pad beneath. The sample passes through transfer medium tape 58 on to tape 60 which is reagent-treated or may be reagent treated in zone 78. The tape 60 may be washed, heated, dried in zone 78 then moves to read-out zone 80.
