Title: Improved moulding grade copolymers and process for preparing the same
IPC: C08F220/06
Filed: 1958-11-06
Abstract: <PICT:0843896/IV(a)/1> A continuous process for the preparation of thermoplastic mouldable vinyl aromatic polymers comprises the steps of (1) preparing the homogenous mixture of monomeric monovinyl aromatic compound e.g. styrene and its derivatives and from 1 to 30% b  by weight of acrylic or methacrylic acid (2) polymerising at between 130 and 160 DEG C. a mixture of the monomeric material and not more than 60% by weight of a copolymer product of the polymerization thereof, (3) maintaining the proportions in the polymerization zone constant by feeding monomer and withdrawing copolymer and monomer mixture at equivalent volumetric rate, the steps being carried out in the absence of iron and finally isolating the copolymer from the mixture.  Alkyl acrylates and methacrylates may be present in small amount to form a terpolymer and a free radical polymeris-a tion catalyst may be included in the monomer mixture and the polymerization may be in bulk or with small amounts of solvent, at a pressure to maintain the liquid state e.g. 25 to 75 pounds per sq. inch.  The temperature and pressure in the polymerization zone are preferably maintained constant by adjusting the feed and withdrawal rate, and the product is isolated by precipitation or devolatilisation.  A kettle type of container may be used or alternatively an apparatus (Fig. 1) comprising a partly jacketed coil 10, with a recirculating pump 11, and metered inlet and outlet pipes 12 and 14.  Temperature and pressure regulating controls 16 and 19 are fitted to make the process automatic and the outlet leads to a conventional devolatiliser.  Articles fabricated from the products have improved dimensional stability.

Title: Process for reducing haze formation in beer
IPC: C12H1/00
Filed: 1961-10-20
Abstract: Proteins which produce haze on storing beer are removed from the beer by mixing in a finely powdered silica gel of 200-400 square metres surface area per gram, pore volume 0.6-1.2 ml./g. and the comparatively wide pore diameter 60-150 , and then filtering off the silica gel, a filter aid such as kieselguhr or cellulose being employed if desired.  The use of 1 g. of the gel per litre of beer for a few minutes is sufficient.  The silica gel is preferably a considerably dehydrated gel which can absorb and discharge water reversibly without volume change.  The silica gel may be washed with water until the content of water-soluble matter is less than 1%, or, preferably, treated with an acid such as hydrochloric or nitric acid before being washed with water to a product having pH 5-7 in a 5% distilled water suspension.  To beer for export, and so more subject to conditions favouring hazing, an antioxidant such as ascorbic or isoascorbic acid or sodium dithionite may be added.

Title: Improvements in or relating to the manufacture of flat glass
IPC: C03B18/02
Filed: 1963-09-25
Abstract: In the manufacture of flat glass, a preformed continuous glass ribbon is slid over a bath of material which is inoxidizable in air at the operating temperatures and has a temperature high enough to give the glass ribbon a fine polish, the ribbon then being slid over the surface of a solid sill substantially a prolongation of the surface of the bath, the sill having a temperature decreasing in the direction of movement of the ribbon so that it is solidified enough to prevent marring of the surface by transporter elements.  A glass ribbon 31 is formed between rollers 1, 2 and passed on rollers 3 on to a bath 18, which may be a molten salt but is preferably of molten silver, in a compartment 12 of a furnace 4 and thence over a solid sill 21 in a further compartment 13, whence it is drawn on to rollers 29 in an annealing lehr.  Heating means 19, 191 and cooling means 24, 241 in the compartments 12, 13 maintain the required temperatures. As shown in <PICT:0995943/C1/1> <PICT:0995943/C1/2> <PICT:0995943/C1/3> Fig. 1, the sill 21 is supported on beams 23 with its top surface 20 level with the edge 22 of a threshold 16 having a top surface 17 inclined with its front edge immersed in the bath 18. The threshold may be formed in one with the sill and the sill may be of silver or of tungsten supported on solid silver, or, as in Fig. 5, a tungsten threshold 16 is set in the silver bath, with that part in compartment 13 being cooled to solidification.  Means are provided to lubricate the solid sill to assist sliding of the glass ribbon 31 thereover.  As shown in Fig. 1, the threshold 16 is of porous material such as steatite and a reservoir 25 below contains a molten salt fed by conduit 26 from a charging reservoir 27, the salt being pressed upwardly through the threshold so that a thin film is formed under the ribbon 31. As shown in Figs. 4 and 5, a conduit 37 of tungsten has an outlet nozzle 38 centrally of the ribbon 31 and just in front of the threshold and a liquid lubricant such as a molten salt mixed with powdered carbon is fed therethrough from a reservoir 39 to just below the top surface of the molten bath 18.  Excess lubricant overflows to troughs 41 from which it is pumped at 44 through conduits 43 back to reservoir 39. In another embodiment, the lubricant in the form of a grease charged with fine carbon powder or a molten salt, is fed to the whole width of the bath 18 at the place where the glass ribbon 31 contacts the bath from the rollers 3.  In a further embodiment, powdered lubricant mixed in liquid silver is forced up and across the bath 18 just in front of the threshold or sill.

Title: Improvements in or relating to ratemeter circuits
Inventor: HALE FRANK HUGH
IPC: G01R23/09
Filed: 1959-11-11
Abstract: 884,317. Radiation intensity measurement. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Oct. 3, 1960 [Nov. 11, 1959; Feb., 9, 1960], Nos. 38334/59 and 4485/60. Class 40(3). The invention is concerned with devices for measuring radio-activity and is particularly applicable to portable battery operated apparatus comprising a scintillation detector, a pulse integrating circuit, and an indicating meter. In such apparatus the power supply for the scintillation counter may have a high internal resistance, being, for example, a neon-stabilized transistor oscillator. Should an excessively high radiation flux fall on the counter the power supply voltage will fall and the meter indication may drop to a value far below that which should be shown. This is particularly dangerous in health monitoring instruments. According to the invention a switching circuit is provided, controlled by the supply voltage, which connects the meter to a current source to maintain its reading at or above full scale if the supply voltage falls below a certain value. In a preferred arrangement the meter M is connected to the output of the integrating circuit and also through diode D2 to the junction of a resistor R1 and Zener diode D1 in series between the +3V battery supply and the -6V stabilized power supply. Normally D2 is reverse and non- conducting and: the meter indicates the integrator circuit output. Reduction of the power supply voltage raises the junction potential:, the diode D2 conducts and current from the battery drives the meter to give a full scale indication. In another embodiment (not shown) two junction transistors forming a trigger circuit are used to switch the battery voltage across the meter when the power supply voltages falls.

Title: Combined receiving and transmitting device for the remote transmission of digital information
IPC: H04L25/45
Filed: 1962-10-10
Abstract: 1,018,604. Telegraphy. OLYMPIA WERKE A.G. Oct. 10, 1962 [Oct.18, 1961], No. 38341/62. Heading H4P. A combined transmitter-receiver for digital information can be switched to function as a transmitter with parallel-to-serial conversion or as a receiver with serial-to-parallel conversion, the two modes of operation using substantially the same equipment. Transmission.-A 1-out-of-10 selection specifying a digit (from a typewriter or calculator) is converted into a five-bit code and stored in a register 29-33 (Fig. 3, not shown). The 1-out-of-10 selection also sets a start flip-flop 25 (not shown) via an OR gate 35 (not shown) to start a clock-pulse generator 20 (not shown) the pulses from which are fed to AND-gates 1-6 (not shown) and to a chain switch 7-12 (not shown) thus stepping it. The stages of the chain switch are thus set (and reset) in turn, and when set each enables a corresponding one of the AND-gates to pass the contents of a corresponding stage of the register to a common output line, except that the first AND-gate passes a clock pulse to the output line. The last stage of the chain switch resets the register and the start flip-flop (thus stopping the clockpulse generator). Further decimal digits may now be sent in like manner. Prior to any transmission, a reset pulse for the register and start flip-flop can be produced by pressing a clearing key to momentarily activate the clockpulse generator.  Reception.-Initial clearing is effected as in transmission or by storing a ONE in the chain switch, progressing it along the switch by means of clock pulses and using the signal from the last stage of the latter to produce clearing. The first signal in the input message (received at 37, not shown) sets the start flip-flop to start the clock-pulse generator, and also passes to the chain switch to set the first stage thereof. The clock-pulses from the generator step the chain switch thus preventing any further message signals from reaching the chain switch and routing the second and subsequent message signals to respective stages of the register via the AND-gates. The register contents are available at output terminals in parallel. A resetting signal from the last stage of the chain switch is produced as in transmission.

Title: Improvements in or relating to electroluminescent devices
IPC: H05B33/12
Filed: 1957-12-10
Abstract: 877,931. Electroluminescence. SOC. D'ELECTRONIQUE ET D'AUTOMATISME. Dec. 10, 1957 [Feb. 28, 1957], No. 38372/57. Class 39(1). A combined photo-resistive and electroluminescent device comprises a frame 2, supporting a thin, fine mesh conductive grid 1 embedded in a layer 3 of photo-resistive material on one face of which is a layer 4 of electroluminescent material having a translucent, conductive film electrode 5 on its free surface. The grid may be made by photoetching a film of copper and preferably has a thickness of two or three microns and a mesh aperture of about 50 microns. It may be annealed by placing in its supporting frame, of nickel for example, and heating to about 900‹C. in a reducing atmosphere. The grid may be embedded in the photo-resistive layer, which is not more than 10 microns thick, by any known method. The electroluminescent layer is constituted by one of the usual compositions of sulphides and oxides of activating and activated materials and has a thickness of 50-100 microns. Such a layer may be obtained by a known method of ionic discharge transfer. The film electrode may be deposited by the evaporation of titanium in air, thus forming a layer of titanium dioxide, but as this has a high resistance per unit area a further superficial layer may be provided by powdering with silver or aluminium and heating to about 200-300‹C. thereby reducing the resistance without impairing the translucence of the film. Specification 851,076 is referred to.
