Filed: 1971-08-19
Abstract: 1302670 Disposable protective suit O SIEGMANN 19 Aug 1971 [2 Sept 1970] 38983/71 Heading A3V A suit, to prevent the entry of infectious agents, made of disposable material e.g. plastics reinforced paper, comprises a coat 1 having a continuous adhesive strip 4 adjacent one edge of an opening slit, which, after the removal of a protective foil 5, constitutes a non- detachable closure for the pressed together edges of the slit. To remove the coat the material must be torn thus necessitating disposal e.g. by burning, to prevent the reuse of the suit and spreading of infectious agents. A hood 2 is also provided with a neck covering extension piece 3 with overlapping front ends, one of which is also provided with an adhesive strip 4 to form a closure when attached to the other front end. Similarly the sleeves are provided with adhesive strips 4 to provide a closure at the wrist.

Title: Improvements in or relating to catalysts and catalytic processes
IPC: C01B3/00
Filed: 1959-11-19
Abstract: Hydrogen is converted to the equilibrium energy slate in the temperature range 20 DEG  K.-240 DEG  K. by passing the hydrogen through a porous bed of ferric oxide gel particles which have been activated by heating to 110 DEG  C.-140 DEG  C.  The ferric oxide gel may be prepared by precipitating from a solution of a ferric salt and a base, washing the precipitate, drying, grinding to the desired particle size, and heating to 110 DEG  C. to 140 DEG  C., preferably for 12-16 hours at a pressure of 1 min. Hg. or less, the vaccum being broken by pure hydrogen gas while the catalyst is still hot.  Heat evolved or used by the interconversion is removed or supplied.  A statement of prior art refers to the use of Cr2O3 on alumina as catalyst for the interconversion.

Abstract: 854,043. Perforating devices. JET RESEARCH CENTER Inc. Dec. 5, 1958 [July 14, 1958], No. 39248/58. Class 9(1). A shaped charge-unit for well-perforating is provided with a liner 21 comprising a multiplicity of small metal spheres joined together at contacting surfaces to provide a porous structure. The unit has a casing 10, which may be a zinc alloy die-casting, covered by a flexible rubber jacket 16. Within the casing 10 is a high explosive charge 20 such as desensitized RDX, in contact with a booster charge 19, such as pure RDX or tetryl, in a cup 17 which communicates with a transverse bore 15 to receive a detonating fuze. The liner 21 is cup-shaped and may have a central boss 26 extending into the explosive, the thickness of the liner increasing gradually from the rim 23 to the boss 26. To make the liner, metal spheres are introduced into a cavity 31 in a two-part mould, Fig. 4, the mould being vibrated during filling. When filled, the mould is placed in a furnace and brought to a temperature at which the spheres weld together due to softening of the spheres or a thin coating covering them. The spheres may be copper and have a diameter of 5 microns. They may have a coating of tin, the ratio of the weights of tin to copper being 5 to 95. The liner may have an outer layer of continuous metal to which the spheres adhere, the metal layer being placed in the mould before closing the two sections together. Specification 785,155 is referred to.

Abstract: 1519658 Position control system SIEMENS AG 22 Sept 1976 [26 Nov 1975]  39394/76 Heading G3N A position control system has a motor drive coupled to a tachogenerator having a permanent magnet rotor 1 and stator windings 2, 3. A Hall generator 6 senses the rotation of rotor 1 and its output passes through amplifier 7 to control power transistor 5, and power transistor 4 via inverter 8, for stator windings 2, 3. Position controller 9 receives a desired position set on resistor 11 and an actual position produced by amplifier 7. Controller 9 output forms a desired value for speed controller 10 which receives actual speed from stators 2, 3. Controller 10 output may serve as the desired value for a succeeding current controller. Thus a separate sensor is not required for position actual value. In another embodiment, rotor 1 can have a separate magnetic track with a large number of poles and an associated additional Hall generator.

Abstract: 1,211,616. Programmed control. GENERAL ELECTRIC CO. Aug.20, 1968 [Sept.28, 1967], No. 39772/68. Heading G3N. [Also in Division H1] In a method of fabricating a plurality of integrated circuit patterns from a master pattern by bombarding a target with a beam of charged particles, the beam is directed on to an array of electro-static lenses and then deflected over a plurality of areas on the target, each area of the target impinged by the beam corresponding to an individual lens and in accordance with the master pattern. The beam may be directed progressively over the array of lenses or a flooding beam may be directed over a plurality of lenses or over the whole array to produce a plurality of integrated circuit patterns simultaneously. The system may utilize a flying spot scanner and optical readout device incorporating a photographic master pattern or a computer, in which case the pattern is stored in the memory bank of the computer. The computer may be programmed to introduce a variation for each lens of the array. The target may comprise a semi-conductor wafer with an electron beam used to polymerize portions of a resist coating or to drive impurities into the wafer by electron beam heating or with an ion beam to implant impurities directly into the wafer. Conventional exposure masks for use in subsequent optical contact printing on the wafer may be produced from a master pattern by exposure of a photographic film to an electron beam or metal masks may be produced using a photo-resist method. In the system of Fig.1 the apparatus includes two condenser lenses 14, 15 and a beam shaping aperture diaphragm 22, "course" deflecting systems 25, 26 for directing the beam 8 orthogonally on to a lens matrix array 23 and a beam blanking deflecting system 36 and Faraday cup 35. The target is indicated at 13. The master pattern 45 is incorporated in the flying spot scanner and optical readout device 50, or alternatively in an imageorthicon tube. The control circuitry includes horizontal and vertical deflection staircase generators 55, 60, 73, 74 driven by pulse counters 61, 62, 71, 72 which are in turn controlled by a clock 63 to produce output pulses at regular intervals. When a flooding beam is used staircase generators 73, 74 are turned off and bias supply 40 is altered to widen the beam. The electrostatic lens matrix comprises three parallel plates 101, 102, 103, Fig.4, having aligned apertures and a crossed-bar "fine" deflecting system 111, 112. The apertures in the central plate 102 are of larger diameter than those of the outer two plates 101, 103. Insulating spacers are provided at 107, 112 and 113. In a modification the aperture diaphragm 22 and condenser lens 14 of Fig. 1 are omitted and a further apertured parallel plate is incorporated in the lens matrix structure, as in Fig.4 at the position of the rear focal plane. Beam shaping apertures in this further plate are then imaged on the target. The beam shaping apertures may be identical or shaped differently for each individual lens.
