Abstract: 1,124,144. Photo-electric photo-meters. CESKOSLOVENSKA AKADEMIE VED. May 26, 1966 [May 28, 1965], No.23634/66. Headings G1A and G1P. In a photo-meter in which an elongated cell 4 has a window at each end 9, 10, and supply and discharge channels 5, 6, at opposite ends so that liquid to be examined is passed continuously along the cell parallel to its optical axis, the latter is inclined at an angle to the horizontal, e.g. 30-80 degrees. Light from source 1 passes through lens 2 and filter 2' to form an image of the source 1 approximately in the centre of the cell 4 before passing to a light sensitive cell (not shown). Two cells may be used passing two solutions in parallel or they may be connected in series for a single liquid. The liquid may be supplied at 5 and discharged at 6, lighter particles and bubbles being carried away whilst heavier particles collect at a sink 13 and may be extracted by a syringe when stopper 16 is removed. Alternatively if lighter particles and/or bubbles are not present but heavier particles are, then the liquid may be caused to flow downwardly.

Title: Improvements in or relating to meters for measuring the flow of liquids
IPC: G01F3/16
Filed: 1958-07-24
Abstract: 846,361. Liquid meters. SCHMITT, R. July 24, 1958 [Aug. 2, 1957], No. 23912/58. Class 69 (2). A liquid meter comprises a piston 7 or vane - dividing measuring chambers 12, 13 which are connected alternately by supply and discharge pipes 16, 17 by a valve 10, 11 controlled by a mechanism 24 rocked in dependence on the movement of the piston, and a stop 26 automatically adjustable in dependence on the difference in pressure in the supply and discharge pipes for limiting the movement of the rocking mechanism. The chambers 12, 13 are alternately connected to the supply pipe 16 by rotation of the valve 10, 11 and ports 14, 15 to impart movement to the piston 7 which is on a rod 8 connected by a bell-crank lever 19, 20 to a link 21, the number of strokes of the piston being transmitted to a counting mechanism 5. Movement of the piston to the right pulls the link 21 downwardly which, by means of a spring 219, rocks the lever 24 secured to a rod 9 connected to the valve 10, 11 from a position abutting a stop 25, which may be adjustable to a position abutting the stop 26 which is in the form of a cone eccentrically mounted on a pin secured to a lever 36. The pressure in the supply pipe 16 is connected by a conduit 33 to one side of a spring-urged piston 29 or diaphragm having a rod 34 connected by a cable 35 to the lever 36. The cylinder 28, in which the piston 29 slides, is provided with slots 38 leading into an annular chamber 31 connected by a conduit 32 with the discharge pipe 17 so that the side of the piston remote from the supply is connected to the discharge pipe. The difference in pressure in the pipes 16, 17, which varies with the flow of liquid through the meter, displaces the piston 29 to adjust the stop 26 and vary the position at which the valve 10, 11 changes over rotation to the position of the piston 7. The slots also permit liquid to flow through the meter in the event of a breakdown in the meter. Chambers formed by covers 4, 6 at the ends of the meter are interconnected by a bore in the piston-rod 8 and filled with the liquid to be measured so that pressure in the meter is in equilibrium.

Abstract: 599,477. Discharge lamps. BRITISH THOMSON-HOUSTON CO., Ltd. Sept. 18, 1945, No. 24088. Convention date, Sept. 25, 1944. [Class 39 (i)] A generator of infra-red radiation comprises a cold cathode discharge tube 1 with a filling of mercury vapour and an inert gas, having an internal layer of phosphor 8, which when excited by the short-wave ultra-violet radiation of the discharge generates longer wave ultraviolet in the range 3400 to 4400 Š in turn, exciting an external layer of phosphor 9 to emit infra-red radiations. The inert gas may have a pressure within a range of a few millimeters to about 10 to 20 millimeters of mercury. The internal layer 8 consists of a cerium activated alkaline earth phosphate, e.g. calcium phosphate, or tungstate with a nitrocellulose binder removed by baking. The external layer is copper activated zinc-cadmium sulphide which contains, prior to firing at least 60 per cent of cadmium sulphide and preferably 70- 90 per cent. The electrodes 4, 5 are of nickel or iron and may be coated with barium, and the envelope is of glass permeable to long ultraviolet radiations, such as lime glass or a borosilicate glass, e.g. Corning glass No. 974 and may be suitably coloured to shield the eye from visible light. Alternatively, both layers of phosphor may be superimposed on one another on the interior of the wall or may be applied as a mixture. The discharge tube may be of the thermionic electrode type with a known circuit arrangement including a thermal switch as in Fig. 2 (not shown). Specification 517,526 is referred to.

Title: Magnetic field sensing ddevice
IPC: G11B5/39
Filed: 1976-06-10
Abstract: 1520084 Magnetic field sensor INTERNATIONAL BUSINESS MACHINES CORP 10 June 1976 [30 June 1975] 24140/76 Heading H1K [Also in Divisions H3 and G5] A magnetic field sensing device comprises a sensor element, e.g. Hall plate or magnetoresistor of magnetic material juxtaposed with a magnetic shunt of greater permeance but with a lower saturating magnetic field, whereby the element exhibits enhanced sensitivity to a range of magnetic fields above that at which the shunt is saturated. As described the sensor element and shunt are sheets separated by a layer of silica and consist respectively of an NiFeCo alloy saturating at an internal field of 10 oersteds and uniaxially anisotropic permalloy saturating at 2 oersteds. The structure may be juxtaposed with a conductor running parallel with the current path through the element. With the conductor connected in a load circuit the sensor element may be disposed in a bridge to operate an overload protection relay in response to currents above the threshold at which saturation of the shunt occurs. In one variant the conductor is a flat strip the width of which increases stepwise whereby alteration of the current enables the shunt to be saturated section by section to vary the range of fields to which the element is sensitive. Similar variations can be achieved with a uniform width conductor and a shunt whose width or thickness varies stepwise. Modifications of the device for use as a magnetic bubble sensor and magnetic type writer keyboard actuator are described.

Title: Production of impact resistant and rigid compositions based on polystyrene
Inventor: DAUMILLER GUENTHER
IPC: C08F36/00
Filed: 1963-06-18
Abstract: Impact resistant graft polymeric materials are made by polymerizing 97 to 70 parts by weight of styrene, or a mixture of styrene and acrylonitrile in a weight ratio of from 90:10 to 65:35, in the presence of 3 to 30 parts by weight of a copolymer of 30 to 90 parts by weight of butadiene and 10 to 70 parts by weight of a C3-C18 alcohol ester of an unsaturated carboxylic acid, the copolymer having a K value of between 50 and 150. Specified carboxylic esters are n-butyl and 2-ethylhexyl acrylates, di-n-butyl and diisobutyl fumarates, and di-n-propyl maleate. The styrene-containing monomeric material may contain minor amounts of other monomers, e.g. alpha-methyl styrene, vinyl toluene or chlorostyrene. In addition to the carboxylic esters of the defined type, the butadiene copolymers may contain minor proportions of other monomers, e.g. methyl methacrylate, cyclohexyl acrylate and vinyl carbazole. The butadiene copolymer may be supplemented by other rubbery polymers, e.g. copolymers of butadiene and styrene or acrylonitrile, polychloroprene, polybutadiene and polyacrylates. The polymerization is preferably carried out by dissolving the butadiene copolymer in the styrene-containing monomeric material with the aid, if desired, of an organic solvent, and heating the mixture in the presence of a catalyst, e.g. di-tert.-butyl peroxide, benzoyl peroxide or azodiisobutyronitrile.  Also present during polymerization may be regulators and lubricants.

Title: Method of and machine for carrying out chemical reactions in the gas phase
IPC: B01J3/08
Filed: 1950-10-09
Abstract: <PICT:0701583/III/1> Endothermic or substantially thermally neutral chemical reactions are carried out in the gas phase by a cyclical process, each cycle of which comprises compressing the reactant gases in a cylinder provided with a piston and allowing the reaction product to expand, the energy necessary to keep the piston in cyclical motion being provided solely by the pressure energy of an inert working gas introduced into the cylinder in each cycle at a pressure substantially lower than the highest pressure occurring in the cylinder.  An inert carrier gas may be mixed with reactant gas or may contain liquid or solid reactant in a dispersed condition. The working gas, e.g. steam, may be introduced during either the expansion stroke or the compression stroke of the cycle; preferably the working gas has a Cp/Cr ratio higher than that of the reactant gas.  The process may be carried out in a number of cylinders with single-acting pistons coupled to a common crankshaft; preferably the apparatus is double-acting and comprises a double cylinder 3 having a double piston 2 which is not coupled to any device for performing external work, and on either side of which is a cylinder space. Movable cylinder heads 9, 91 connected by rods 11, 111 reciprocate with the piston, and the moving parts may be interconnected by lever 21 and rods 22, 23, or by a rack and pinion arrangement.  The masses of the reciprocating parts are inversely proportional to their length of stroke.  Reactants enter at 14 into a shell 13 and pass to the cylinder spaces through parts 5, 51, working gas is admitted through ports 6, 61, and reaction products leave through ports 4, 41 and pipe 12.  The admission of working gas is controlled by a slide valve operated by stops on the rod 11.  In an alternative arrangement Figs. 6-8, (not shown) the cylinder has fixed heads and slides as a whole on the machine frame.  Reference is made to the cracking of hydrocarbons (e.g. paraffin wax) and the chlorination, oxidation, and nitration of unsaturated organic compounds.

Title: Improvements in and relating to folded dipole aerials
IPC: H01Q9/26
Filed: 1948-09-21
Abstract: 652,716. Aerials. COSSOR, Ltd., A. C., WYNN, A. H. A., and OXENHAM, J. K. Sept. 21, 1948, No. 24732. [Class 40 (vii)] The invention relates to folded dipole aerials of the type comprising a centre-fed dipole and a further conductor or conductors disposed alongside the dipole with connections between points at or near the ends of the dipole and corresponding points at or near the ends of the further conductor or conductors, the structure having a part annular form. According to the invention, the conductors forming the dipole and the further conductor or conductors are arranged on opposite sides of one or more insulating members. Each insulating member may be a flat plate and the conductors applied to the plate by a printing process ; by spraying through a mask; by sputtering; or by providing the plate with recesses, coating the whole surface with a conductor, and then removing the raised portions of the support by grinding. In Figs. 3 and 4, the upper and lower surfaces respectively of an insulating sheet carry thin strips of conducting material (shown shaded). E and F constitute the input terminals and rivets are passed through the sheet to join points J, J<SP>1</SP> and K, K<SP>1</SP>, the whole assembly forming a folded dipole with conductors bent to follow the sides of a square. It is shown that by suitable choice of the points of connection between the dipole and further conductors, the aerial input impedance may be made resistive and that this may occur at a frequency lower than the resonant frequency of the dipole. At a given frequency an aerial constructed according to the invention may have smaller dimensions than a normal dipole. By making the conductor on the under surface broader than that on the top, as shown in Fig. 4, the aerial input resistance is increased. In a second embodiment, Figs. 6 and 7 (not shown), two conductors are provided on the under surface to produce a doubly folded dipole. Multi-folded dipoles are produced by employing a plurality of supports, Figs. 9-11 (not shown). Specification 652,398, [Group XL (b)], is referred to in connection with the methods of applying the conductors to the insulating support.
