Abstract: 1436030 Protection from X-rays E A GADE 30 Aug 1974 [8 Sept 1973 13 Feb 1974] 38122/74 Heading H5R To screen from X-rays the gonads of a patient undergoing diagnostic radiography, in the use of an X-ray tube fitted with a scattered radiation shield 4 and a collimator with light source to indicate the field of the X-ray beam, a fitting comprising longitudinal channel rails 9, e.g. of Al, and affixed transverse hollow arms 10, also e.g. of A1, is slipped on to the auxiliary attachment rails 6 provided with the X-ray apparatus, and carries in the slots in arms 10 an adjustable thin support strip 2 made from plastics transparent to light and X-rays and bearing within its thickness a plate, e.g. of lead, opaque to X-rays and of the shape necessary to block that part of the X-ray beam which would strike the gonads. The strip, at least twice as long as rails 9 and narrow compared with the length of the slots, is adjustable before exposure to bring the optical and thus the X-ray shadow over the critical area. Four alternative strips are provided, carrying respectively patterns for male and female adults and children (16, Figs. 4, 5, 6, 7, not shown). The strip is gripped in the slots by springs or by strips of pile fabric.

Filed: 1960-11-11
Abstract: 936,310. Exothermic compositions. AEROJET-GENERAL CORPORATION. Nov. 11, 1960, No. 38850/60. Class 82. [Also in Groups XXI and XXVI] A solid heat-generating charge for a torpedo comprises an intimate mixture of a finely divided metal of low atomic weight, such as aluminium, together with an oxidizer which may be the perchlorate, chlorate, chromate, dichromate or permanganate salt of an alkali or alkaline earth metal. The metal and oxidizer, present in stoichiometric proportions, are bonded together by being subjected to pressures within the range 2000 to 7000 kilograms per square centimetre and according to the invention such a charge, on burning, forms substantially only solid or liquid products of combustion. The torpedo 10 has such a propellent charge at 15, placed within chamber 14. To restrict the burning area, the mixture of metal and oxidizer may be placed in the chamber 14 and the latter subjected to high pressure, whereupon a solid charge is formed bonded on its outer surface to the walls of the chamber. For replaceable charges restriction of burning to a selected surface is obtained by suitably wrapping the mixture with a thermoplastic polyester resin impregnated fabric which is cured on the mixture after pressure has been applied.

A gripper-operated packing or unpacking machine for bottles &c. has a double row conveyer belt for the crates 6, and grippers 4 suspended from a gripper head 2, with a displaceable section 17, attached to a carriage 5. In the packing operation bottles 3 are brought by a belt 10 on to a shelf 1, lifted a short distance by the grippers 4 under the action of a hydraulic device 13, and carried to a position over the crates by movement of the carriage 5. As the carriage nears the edge of its path, a stop shaft on the section 17 of the carriage engages stops on the machine frame, thus increasing the distance " t " between the two central rows of bottles to " t<SP>1</SP> " to allow for the extra width between the outside walls of two adjacent crates. The bottles are lowered into the crates and the grippers released and lifted. The carriage returns to its original position and the section 17 retracts under spring action or by the stop shaft thereon engaging a second set of stops on the machine frame.

Abstract: 1381519 Stepping motors XYNETICS Inc 31 Aug 1972 [8 Sept 1971] 40461/72 Heading H2A In a positioning arrangement providing con-  trolled relative movement between a head and a base member and operating on a stepping-motor principle, e.g. as described in Specifications 1,197,065 or 1,257,251, the head and base member are both generally cylindrical, and the head carries two energizing systems co-operating with respective sets of ribs on the base member to provide two degrees of freedom in the movement of the head relative to the base member. In one embodiment (Fig. 1, not shown) the base member carries both annular and longitudinal ribs so that both longitudinal (axial)and rotational movement can be obtained. In another embodiment (Figs. 3, 4) the base member 300 carries two sets 302, 304 of helical ribs. A first core assembly 308 on the head comprises a plurality of angularly-spaced toothed salient poles. Each pole is made to extend helically (e.g. by skewing the stack of laminations) so that the teeth 316 co-operate with the ribs 302 to produce corkscrew movement in one sense when the coils 314 on the salient poles are sequentially energized. A second similar core assembly 310, spaced from the first by an annular permanent magnet 312, provides corkscrew movement in the other sense. By energizing both core assemblies any required combination of longitudinal and rotational movement can be obtained.

Abstract: 852,391. Bistable state circuits using thermionic valves. GENERAL RADIO CO. Dec. 16, 1958, No. 40533/58. Class 40(6). A bistable counter circuit comprises an amplifier stage which has series connected D.C. coupling means in both the input and output circuits and a shunt connected stage disposed in the input circuit which has a low D.C. impedance but a high impedance to incremental voltage changes. The Figure shows a bistable-state trigger circuit comprising reciprocally coupled tubes 1, 3 to which trigger impulses P are applied via the anode circuit of the two tubes and in which the tubes 2, 4 are connected in the input circuits of each stage as constant current devices so as to produce a low direct current impedance but a high incremental voltage impedance, In this way the bistablestate can be caused to switch at very high repetition frequencies since the constant current tubes 2, 4 permit very high speed recovery of the input circuits of the tubes 1 and 3 after they have been cut off. The capacitors 25, 27 are made large so that the input capacitance of the stages 1 and 3 cause negligible reduction of gain at the high frequencies of switching the normal charging or memory function of the capacitors is provided by inductors 33 and 35 the voltages developed across which provide an indication of which of the tubes 1 and 3 was previously passing its full anode current.

Abstract: 1440525 Screw conveyers H J BUTTNER 31 Aug 1973 41176/73 Heading B8A [Also in Divisions F4 and B1] In an apparatus in which fluent material particularly a paste or sludge is conveyed by a rotating screw H through a housing D (e.g. from an inlet at one end to an outlet at the other end of the housing during which time the material is heated or dried and subjected to a mixing action, a plurality of balls B (e.g. of metal, refractory, or plastics material) are maintained in rolling or sliding contact with the screw for preventing or removing material deposits thereon, the balls being continuously recirculated through the housing (e.g. via a recirculation channel P). Ports V are provided for the withdrawal of volatile components of the material produced during heating or drying. Heat may be supplied to the apparatus by any one or more of the following means: (a) from the screw itself (when the screw is hollow and is heated by steam or by a burner), (b) through the wall of the recirculation channel P and screw housing D by steam or burner gases flowing in a jacket J, Fig. 2; or by a burner applied externally to the jacket, (c) by the balls themselves which may be heated either directly or indirectly.  The balls are constrained to progress in the general direction of the screw axis in a straight or curved path, by channels C formed in the wall of the housing D. Numerous arrangements are decribed for removing the balls at the lead-off end of the screw and for returning them from the channel P to the lead-on end of the screw. The balls may be cleaned as they leave the screw by scrapers (e.g. 20, Figs. 7 and 8). Several screws may be utilized in the same apparatus, each having its own ball recirculation system (see e.g. Fig. 3); or as shown in Fig. 4, an additional screw M of conventional form may be used and may be rotated either independently or by contact with the flutes of a screw H.
