Title: Improvements in or relating to tables for positioning patients for examination and treatment by means of x-rays, gamma rays, or the like
IPC: A61B6/04
Filed: 1959-08-21
Abstract: 894,500. X - ray examination tables. SIEMENS-REINIGER-WERKE A.G. Aug. 21, 1959 [Aug. 28, 1958], No. 28736/59. Class 98(1). A patient-supporting table for use with radiation apparatus has a length of at least 2.4 metres, and is recessed along at least one of the longer edges at about one-third of the distance along the table. Thus absorption of radiation by the table top is avoided at these recessed portions when the radiation source is below the table. In the form shown, the length of the table is three metres, a section 29 at one end being hinged to the remainder. It is normally supported by a rail 31, which can be retracted to allow the section 29 to be dropped. Two recesses are shown, each having an outer part 37, 38 and an inner part 35, 36. The patient is positioned so that the part to be examined or treated is over one of the recesses. The length of the table is such as to allow considerable latitude in the positioning of the patient along its length. A rack and pinion arrangement under the table provides a small degree of longitudinal adjustment. The recesses can be partly or completely filled by removable segments, as required. When the radiation source is to be used above the table, the entire table top can be covered with a plastic sheet.

Abstract: 891,711. Glass compositions; enamels. ENGLISH ELECTRIC CO. Ltd. Sept. 11, 1958 [Sept. 13, 1957], No. 28859/57. Class 56. A glass or enamel composition contains not less than 36 molecular percentage of oxides of manganese, the manganese ion being present in at least two states of valency but the percentage being expressed as manganous oxide (MnO) and the proportion of manganese ions in each of the states of valency being such that the glass or enamel exhibits electronic conductivity. The balance of the composition consists of up to 5 alkaline earth oxides, 0 to 20 Al 2 O 3  and 35 to 56 SiO 2 , the MnO being 36 to 55, all in molecular percentages. The alkaline earth oxides used are those of calcium, barium or magnesium. In one process, manganous carbonate, calcined alumina and ground quartz are melted at 1,400C. in air, cast and moulded then annealed at 650C. before grinding and polishing. The shaped article is then heated in an oxidising atmosphere which may be air, at less than the softening temperature between 550C. and 700C., for 4 hours, to form an electronically conductive surface layer. In a process giving thin films, the glass is blown, using a silica or stainless steel tube, to a thickness between 10<SP>-4</SP> and 5x10<SP>-4</SP> inches. In a further process, powdered glass is heat-treated and then sintered in an inert atmosphere to form an article, or the powdered glass may be sintered in air or other oxidising atmosphere. The compositions may also be used as electronically conducting glazes for application to ceramic insulators or other articles.

Filed: 1928-10-08
Abstract: 324,047. Thide, C. S. Oct. 8, 1928. Kinematograph apparatus.-Electrical changeover and cut-off means for two or more projectors comprise, for each projector, an electrically operated cut-off shutter, circuits for the operation of the shutter, and a selector switch, the change-over or cut-off being effected by first appropriately setting the selector switches, and, when the operation is to be effected, manually connecting with a source of power; the cut-off shutters may be placed to function at the smallest cross section of the light beam. As shown in Figs. 3 and 4, asbestos or like plates 12, 13 are carried by the projector head 9. and a cut-off shutter 24 comprising one or two plates is connected by links 26, 28 to a bell-crank 27 linked to the core 31 of a solenoid. The solenoid has two windings which may be separately energized to pull the core in opposite directions and raise or lower the shutter, and the parts are held in each of the extreme positions by a spring 27a. A cut-off shutter 16 is also provided, and is operated by hand through a lever 23 engaging a pin 20 on a lever 19 connected by a link 18 to the shutter. Fig. 7 shows the connections for three projectors. A double-throw selector switch 53 is provided in a switch box for each projector, a conducting switch-lever 50, capable of being temporarily depressed by the foot &c. of the operator, against the action of a spring 52, to bridge contacts 47, 49 and leave a contact 46, being also provided in the switch box. The switches, contacts, and the windings 37, 38 of tha solenoids 40 are electrically connected together, and to a source of power G, as shown. If projector C is operating, and change-over to projector B is to be effected, the selector switch 53 of projectors B and C are initially set as shown, and selector switch 53 of projector A is left in neutral position. When change-over is to be effected, lever 50 of projector C is temporarily depressed to the position shown, with the result that winding 37 of the solenoid of projector C is energized to close the shutter of this projector, and simultaneously the winding 38 of the solenoid of projector B is energized to open its shutter. By appropriately setting the selector switches, other change-over operations or a cut-off may be effected, or the operations may be effected by means of switches 61 at remote points connected in parallel across the contacts 47, 49.

Title: Improvements in or relating to the purification of chlorine
IPC: C01B7/07
Filed: 1956-09-24
Abstract: <PICT:0845550/III/1> Organic impurities are removed from gaseous chlorine by passing superheated chlorine through a bath of liquid chlorine and then in countercurrent to a flow of liquid chlorine. The liquid chlorine from the bath is continuously removed at a rate such as to maintain the impurity content constant, and the liquid chlorine so withdrawn is heated to vaporize chlorine which is mixed with the superheated chlorine entering the process.  In the Figure the liquid chlorine baths arranged in parallel are shown at 10, 12. Gaseous chlorine is introduced through lines 18 and 14 and nozzles 3, 5.  The partially washed chlorine is led via line 46 to a scrubbing tower 48, where it is contacted with liquid chlorine in countercurrent flow.  This liquid chlorine may be obtained by condensing some of the gaseous chlorine either in the top of the tower or in a separate condenser 58.  Liquid chlorine is continuously removed from the baths 10, 12, via 36, 38, 40, and is purified by distillation in column 72 and reboiler 74.  Gaseous chlorine passes through line 76 to join that entering at 18.  The baths are replenished from the base of the tower 48 via the line 39.  As shown, purified gaseous chlorine is liquefied in condenser 58.  A portion passes back to the column through line 64, while the product chlorine is withdrawn from tank 60 as a gas via 66 or liquid through line 68.
