Title: Improvements relating to radioscopy
IPC: A61B6/04
Filed: 1962-06-21
Abstract: 938,410. Radioscopic apparatus. COMPAGNIE GENERALE DE RADIOLOGIE. June 21, 1962 [July 21, 1961], No. 23969/62. Class 98 (1). Radioscopic apparatus comprises a table and a compression member, relative movement between table and member being possible perpendicular to the table top, the compression member being so mounted that, when in contact with a patient lying on the table, the member can move in mutually prependicular directions in a plane parallel to the table top without moving the point of contact with the patient. In the form shown, the compression member is a hemispherical pad 7 supported, from a mounting 5, between an X-ray tube 3 and an examination table 2. It can be moved vertically towards or away from the table, so as to be brought into contact with a patient lying thereon. The pad is supported by two arms 12, 13 pivoted at the ends of a fork 11 fixed on a shaft 10. Thus the pad can turn about two mutually perpendicular axes, intersecting at the point A, in a plane parallel to the table top. If, therefore, the pad is lowered until it is in contact with a patient lying on the table, and the latter moved a limited distance in any direction, the pad can follow the movement without the point of contact with the patient being varied. In an alternative arrangement (Fig. 4, not shown), the pad is fixed in a sliding frame which can itself slide in an outer frame, thus again allowing movement of the pad in two mutually perpendicular directions.

Patent GB-711957-A (GB)
Title: Improvements in or relating to record card controlled printing machines
Inventor: RIGBY IVOR VIVIAN
Filed: 1950-10-02
Abstract: 711,957. Addressing machines. BRITISH TABULATING MACHINE CO., Ltd. Sept. 28, 1951 [Oct. 2, 1950], No. 24026/50. Drawings to Specification. Class 100 (2) A printing machine in which plates, e.g. address plates, are fed sequentially to a printing position is controlled by sequentially fed record cards, both the record cards and the plates having data thereon which is sensed and when found to correspond cause operation of control means to effect printing; the record card having also a further code to determine the number of impressions to be made from each plate. There is no mechanical interconnection between the feed of the record cards and the printing plates, the latter being dependent upon electrical circuits which control mechanism for (a) effecting no printing, (b) effecting one impression from one plate or (c) effecting two to eight impressions from one plate. Each record card comprises a group of data in three columns representing the units, tens, and hundreds of a control number, e.g. an account number, which is sensed by a mechanism similar to that shown in Specification 190,144, [Class 106 (i)]. Each card effects one impression provided its control number agreed with the data sensed in the printing plate by a mechanism similar to that described in Specification 495,083. The further code on the record cards forms a print control so that repeat impressions from the same printing plate can be made. During the first card feeding cycle a card lever control operates which causes the machine to stop if the supply of cards ceases. During the next cycle the card is sensed, and during these first two cycles a printing plate is fed from a magazine and sensed by the plate sensing mechanism. When the data on the cards and plates agree a circuit is established to operate a solenoid controlling a storage plunger associated with a storage drum mechanism described in Specification 648,975 so that when the particular plate reaches the printing position an impression is made. There are four cycles of operation between sensing of a plate and printing therefrom so that the print control code is stored by a series of relays which transfer the code from one set of relays to the other as the card approaches the printing position where the value of the code is interpreted to effect the appropriate number of impressions. The plate feeding mechanism is halted during repeat impressions. The following plates which are in the cyclic positions between the sensing and printing cycles have their plate code data stored on the corresponding series of relays. At each feed cycle the plates advance one position and the code data is transferred to the next series of relays so that, when the plates arrive at printing position, the code also arrives to control printing. Specification 558,793, describing the plate feeding and printing mechanism also is referred to, and Specification 317,490, [Class 100 (ii)], is referred to in the Provisional Specification.

Title: Improvements in or relating to universal joints
IPC: F16C11/08
Filed: 1937-09-03
Abstract: 484,058. Making universal joints. MEYER, L. W. (Thompson Products, Inc.) Sept. 3, 1937, No. 24065. [Classes 83 (ii) and 83 (iv)] [Also in Group XXV] Forging-punches.-A method of making a universal joint, such as a tie-rod joint, having a headed stud member freely rotatable and tiltable in a housing, includes the steps of providing in the housing a bearing wall of soft metal such as Woods metal or the alloy known under the Registered Trade Mark " Babbitt." which materials may be impregnated with graphite or other lubricant, and pressing the stud head into the wall to form a bearing surface for itself thereon. A ring 16 of soft bearing metal having parallel or inclined walls is pressed into a housing 10 by a tool 23, a tapered portion 22 on which shapes the inner surface of the ring 16. Excess metal is forced out through the aperture 14. The stud 25, Fig. 5, is then forced in by a tool 28, the spherical surface 26 deforming the ring 16 to form its own bearing surface. In a modification, a pair of opposite bearing surfaces separated by recesses 47, 48 are formed by a tool 40 having projections 43, 44, the stud being pressed in to deform the bearing surfaces as in Fig. 5. In the assembled joint, a spherical projection 27 on the stud engages a retainer member 34 which is held in engagement therewith by a spring 35.

Title: On load tap-changing equipment for an electrical transformer
Inventor: GRIERSON RICHARD ALAN
IPC: H01F29/04
Filed: 1960-07-12
Abstract: 924,130. Transformers. BRUSH ELECTRICAL ENGINEERING CO. Ltd. Jan. 6, 1961 [July 12, 1960], No. 24216/60. Class 38 (2). In a single or multi-phase on-load tapchanging system vacuum switches of a type employing solid contacts are used as tap selecting switches or as load-breaking switches or to perform both functions combined. Fig. 1 shows a divided transformer winding A1, A9 with tapping points including vacuum switches 3-8 on the upper part connected respectively to the lower part of the winding via saturable reactors T1, T2. A further vacuum switch 2 is connected across T1 and T2. With any one tapping in operation reactors T1 and T2 are saturated and vacuum switch 2 is closer so that the load current flows equally through T1 and T2. To change tapping 3 to 4, T1 is brought to maximum impedance and the vacuum switch connected to tapping 4 is closed after which T1 is brought to minimum impedance and T2 to maximum impedance and the vacuum switch connected to tapping 3 is opened. Fig. 3 shows another embodiment incorporating a conventional tapping selector switch with two movable contacts C1 and C2 each connected through a vacuum switch S1 or S2. Resistances or inductances may be used instead of the saturable reactors. The sequencing of the steps can be effected by movement of an external selector and a self-cycling switch may make the various changes in the saturating current of the reactors. The external selector may be operated automatically in response to variation of a characteristic of the load circuit. The vacuum switches may either be of the kind having their contacts secured to the relatively movable walls of an enclosing evacuated envelope or of the kind having a rigid envelope enclosing an electromagnetic coil by which at least one biased contact can be moved relatively to the other. The complete tap-changing equipment may be housed in the main transformer tank.

Abstract: 894,301. Valves; fuel injection engines; charge compressors. BUCHI, A. July 30, 1958 [Aug. 8, 1957], No. 24557/58. Classes 7(2), 7(3) and 7(6). In a two-stroke engine with tangential pistoncontrolled inlet ports 9, Fig. 8, the exhaust is controlled by a pair of coaxial exhaust valves 10, 11, in the cylinder head leading to chambers 16, 28, in which the exhaust gases rotate in the same direction as is imparted to the air in the cylinder by the inlet ports 9. The inlet ports 9, Fig. 5 are inclined to produce rotation in the air in the cylinder and are surrounded by fins 1<SP>1</SP> or by a spirally shaped chamber which assist the production of rotation. The scavenging air may be supplied by a mechanically driven compressor, or, as shown, by an exhaust driven turbocharger 38. The passages 16, 28, around the exhaust valves are spirally shaped, Fig. 3 (not shown), to cause the gases to whirl around the valve axes and they may merge into a common exhaust pipe or, as shown, lead to separate exhaust pipes 17<SP>1</SP>, 17<SP>11</SP>, which deliver into separate turbines or turbine stages or separate entry chambers of a turbine. The valves 10, 11 may open simultaneously but preferably the valve 11 opens before valve 10 and closes after valve 10 has closed. The turbocharger 38 delivers through a cooler 45 into a scavenging air chamber 14 to which is connected an engine driven supercharger 43 feeding supplementary inlet ports 9<SP>1</SP>, blow back through the supercharger being prevented by flap valves 42. The inlet ports are directed towards the combustion chamber recess 32 in the piston to ensure scavenging thereof and the fuel injector 30 injects tangentially into the recess 32.

Title: Improvements relating to methods of manufacturing oxide-coated cathodes
IPC: H01J9/04
Filed: 1966-06-02
Abstract: 1,115,236. Cathode materials and processing. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 2 June, 1966 [5 June, 1965], No. 24574/66. Heading H1D. In the manufacture of an oxide coated cathode a coating of barium and strontium carbonates applied to the cathode support is first heated to convert it into oxides, then heated again in an atmosphere of carbon monoxide and carbon dioxide to reconvert the oxides into carbonates. The cathode is then built into an electron tube and the carbonates converted again into oxides by firing the cathode during evacuation of the tube. The process allows greater control over the thickness of the oxide layer since on final conversion to oxide the layer shrinks only 1 to 2%. The barium-strontium carbonate coating may be formed on a nickel cathode support by painting, spraying or by cataphoresis. The first conversion to oxide takes place in an evacuated vessel at between 1000‹ and 1100‹ C., the vessel is then filled with a mixture of carbon monoxide and carbon dioxide, formed, for example, by equal parts by weight of these gases, and the cathode heated at between 800‹ and 850‹ C. to reconvert to carbonates. The cathode support is cooled whilst still in the gas mixture. The final oxide coating may be between 50 and 100 microns thick and the interelectrode spacing may be less than 100 microns. Before mounting in the tube the cathode may be coated with a protective layer of nitrocellulose.
