Title: Improvements in or relating to indicating arrangements for ring scaling circuits
Inventor: JAMES JOHN BERNARD
IPC: H03K21/08
Filed: 1956-08-16
Abstract: 841,614. Circuits employing bi-stable magnetic elements. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Aug. 1, 1957 [Aug. 16, 1956; Feb. 26, 1957], Nos. 25039/56 and 6495/57. Class 40 (9). [Also in Group XIX] In a counter comprising a ring of bi-stable elements 0-9, Fig. 1 (Prov. 25039/56), the position of the count is indicated by a pivoted polarized needle 10. The bi-stable elements may comprise toroidal or bar magnetic storage cores, the necessary leakage flux in the case of toroidal cores being established by an air gap, Fig. 3 (not shown), or by regions of reduced cross-section, Fig. 2 (Prov. 25039/56). In the latter embodiment, two oppositely-polarized needles 13, 14 may be used to balance out the earth's magnetic field, or a single needle assembly may be enclosed in a ferromagnetic case. The pivoted needle may alternatively be associated with a ring of auxiliary storage cores which are magnetized in correspondence with the count position in a separate counting circuit, each auxiliary core having a winding which is connected in series with a counting core and may be shunted by a non-linear resistor. In one arrangement, Fig. 1 (Prov. 6495/57), auxiliary high-remanence cores 21-24, each with two windings 31-34, 41-44, are associated with bi-stable counting elements 1-4, the connection between adjacent counting-elements comprising series-opposed windings, such as 31, 42, on two adjacent cores so that a single auxiliary core only acquires a characterizing magnetic polarity at any time. In an alternative arrangement, Fig. 2 (Prov. 6495/57), the windings on alternate cores, such as 31, 43 on cores 21, 23, are connected in series opposition, with the result that two adjacent cores have a characterizing polarity which is indicated by midway positioning of the needle 10. The counting elements may alternatively comprise transistors, in which case the auxiliary cores must have remanence properties. Specifications 841,613 and 841,616 are referred to.

Title: Improvements in or relating to heating installations
IPC: A61L2/06
Filed: 1960-07-18
Abstract: 896,409. Valves. LINDER, F. July 18. 1960, No. 25044/60. Class 135. [Also in Group XIII] A heating installation (see Group XIII), wherein heated vapour is supplied to an apparatus such as a sterilizer 1 from a heat accumulator 3 incorporates a combined safety valve and thermally-actuated valve which opens to allow waste air to discharge from the sterilizer and closes when steam flows through the valve. The valves are housed within a body 12 through the bottom of which projects a finned pipe 11 conveying air or steam from the sterilizer. The safety valve consists of a weight-loaded cylinder 13 having a nipple seating in the end of the pipe 11 and bored to provide a passage terminating in a seating engaged by a check valve 14. Housed within the cylinder 13 is a bellows 15 containing a liquid, for example, ethanol, whose boiling-point is lower than that of water and having an extension 16 which can engage the check valve to hold it closed. When steam enters the sterilizer it displaces air through the valve, the air flowing through a pipe 17 to atmosphere through water in a tank 18. When steam begins to flow through the valve the bellows 15 expands and closes the valve 14 and a closed circuit circulation of the heat transfer medium is instituted, an occurrence of excess pressure in the sterilizer being relieved by the valve 13.

Title: Improvements in or relating to high speed optical parallel-to-serial and serial-to-parallel conversion of binary information
IPC: H03M9/00
Filed: 1965-06-15
Abstract: 1,070,569. Binary information transmission arrangements. INTERNATIONAL BUSINESS MACHINES CORPORATION. June 15, 1965 [June 30, 1964], No. 25184/65. Heading G1A. [Also in Division H4] In an arrangement in which, for transmission purposes, simultaneously existing binary information is converted to a sequence of light pulses or vice versa the active elements comprise a sheet of plane polarizing material and an optical analyzer, the plane of polarization of which is at right angles to that of the first sheet, sandwiching between them an electro-optical crystal capable of changing the plane of polarization of light transmitted therethrough under the influence of high potentials applied to the end of a pair of semi-transparent surface electrodes. The light from a plurality of lamps on which the binary information is displayed, is directed to selected spots on the surface of the crystal and the applied high voltage pulse, in traversing the electrodes, sequentially changes the polarization of the light passing through the selected spots to enable its passage through the analyzer. Lenses in the spot paths direct the light pulses on to a common point (a photo-cell) to produce the sequence. In the converse arrangements a light pulse of a sequence is applied to the whole of the polarizing plane and to the entire surface of the crystal element, to be picked up beyond the analyzer by individual photo-cells as the voltage pulse activates successively the selected spots on the crystal. Use of the converters in a transmission system in which the sequence is transmitted over a light beam is described, the output sequence from a converter of the first type being applied to a high-speed semiconductor photo-diode and the resulting signals, after amplification, generating the light beam in a lasing diode such as of gallium arsenide. The transmitted light may be directly applied to the polarizer of the receiving converter or may be detected to regenerate a local light signal and led to areas corresponding to the selected spots through optical fibres. A trigger pulse controlling the application of the remote scanning voltage is transmitted over an auxiliary light path and an adjustable delay line. A crystal suitable for the scanning of a plurality of lines of lights is described with reference to Fig. 4 (not shown) and a segmented crystal arrangement is described with reference to Fig. 5 (not shown). The electrodes are terminated by an impedance to prevent reflection; and the Specification includes a formula for each an impedance. Dimensions and transmission times are exemplified.

Title: Spray head
IPC: B05B11/04
Filed: 1975-06-12
Abstract: 1505896 Spray-producers SOC DES PLASTIQUES BRENEZ SARL 12 June 1975 [29 Nov 1974] 25257/75 Heading B2F A spray head for an atomization dispenser suitable for spraying liquids or powders comprises a first part 9 mounted on the dispenser body, said first part having a central frustoconical portion 13, a depending skirt 15 which is threaded for engagement with a bottle 16  serving as a reservoir for the spray material, and a transverse upper portion provided with two orifices 20, one of which communicate with a tube 22 extending into the bottle; a second part 10 of frusto-conical shape mounted on top of the frusto-conical portion of the first part and having an outlet 23 for discharging the spray material; and a third part 11, also of frusto-conical shape, mounted on the first part and surrounding the second part and the frusto-conical portion of the first part, said third part having a spraying aperture 34 and being spaced from the first and second parts to form an air passageway 25 which communicates with the interior of the dispenser body via orifices 26 in the first part of the spray head, said first part also having an annular groove 17 communicating with the air passageway and defined by a wall 19 which is at least partly flexible and is capable of shutting off the communication of the air passageway with the interior of the dispenser. The dispenser body comprises two tubes 1, 2 and a valve 4, the tubes being slidably movable relative to one another to act as an air-compression pump. During the compression stroke, compressed air passes through the valve and into the interior of the dispenser body where it acts upon the resilient walls of the bottle 16 and forces spray material via the tube 22 and the orifice 20 to the outlet 23 where it is discharged in the form of a hollow jet, said jet being atomized by air arriving via the orifices 26 and the passage 25. When the pressure ceases, the flexible wall 19 bears against a skirt portion 27 on the third part 11, thereby eliminating all communication between the air passage 25 and the interior of the dispenser body. Any droplets flowing down the inner walls of the spray head accumulate in the groove 17 and are thus prevented from coming into contact with the internal walls of the tubes 1 and 2; a bevelled edge 28 on the skirt 27 helps to direct the droplets into the groove. Specification 1372763 is referred to.

Title: A method of and apparatus for producing artificial filaments containing effect materials
IPC: B01F25/62
Filed: 1957-08-12
Abstract: Artificial fibres containing in predetermined and constant proportions one or more effect materials are made by continuously introducing into and mixing with a spinning solution at a constant predetermined volumetric ratio a minor proportion of another liquid containing a relatively high proportion of the effect material <PICT:0866336/IV (a)/1> or materials, the introduction being effected into at least one partial flow of a temporarily divided stream of the spinning solution in a mixing gear pump where this partial flow is set into circulation under atmospheric pressure, and extruding the spinning solution to form filaments.  As shown, a spinning solution is fed through a pipe 10 to the inlet 11 of the gear pump 12 in which the solution is divided into two parts, of which the first part is discharged through the outlet 13 and delivery pipe 14 without the addition of another liquid.  The second part of the spinning solution is forced by the pump through the outlet 15, delivery pipe 17, mixing chamber 18, and pipe 26 back into the pump through the inlet 16.  In the chamber 18 the second part of the spinning solution is mixed at a predetermined rate with a liquid containing an effect material from a storage container 20 by means of a mechanical metering device 19 which has a common drive with the pump 12.  Surplus liquid is discharged from the chamber 18 through either a pressure relief valve or an overflow tube 21 into a receiver 22 or to the inlet of a pump 23 which delivers the liquid into pipe 14.  The spinning solution returned to the pump 12 through pipe 26 and pump inlet 16 contains twice the required concentration of effect material and is divided into two parts.  One part is returned to the mixing chamber 18 through pipe 17 and the other to the discharge pipe 14, whence it flows to the spinning machine.  Modifications of the apparatus shown in Fig. 1 are described (Figs. 2-5, not shown).  The effect material may be a dissolved dye, a dispersed powder such as an insoluble pigment, a paste or a dispersed gas.  Specifications 460,955 and 576,263 are referred to.

Title: Improvements in or relating to plain bearings
Inventor: FORRESTER PETER GARNETT
IPC: C22C9/00
Filed: 1950-10-18
Abstract: A cast bearing material, consisting of 10-40 per cent lead with the remainder copper with or without tin, silver, nickel, iron, zinc or phosphorus up to a total of 5 per cent is heat treated at temperatures above the melting point of lead but below the solidus temperature of the copper-lead for a period sufficiently prolonged to change the "as-cast" structure to one consisting of interlaced sponges of copper and lead.  The process is preferably carried out in an inert atmosphere.  The period of heat treatment may be reduced by preliminary light cold working and any lead exudation minimized by preliminary heat treatment according to Specification 663,215.  In an example given, a bearing material consisting of about 30 per cent Pb and about 1 per cent Sn or about 40 per cent Pb and about 0.5 per cent. Sn, with the remainder Cu in each case, was treated in a protective atmosphere at about 900 DEG C for about 24 hours.  In this case the heat treatment was reduced to about four hours by preliminary light rolling.

Abstract: 1,146,890. Aqueous dispersions of polyurethanes. FARBENFABRIKEN BAYER A.G. 5 June, 1967 [8 June, 1966], No. 25809/67. Heading C3R. Aqueous dispersions of polyurethanes are obtained from polyurethanes prepared from a compound containing reactive hydrogen atoms at least one of which is contained by a hydroxyl group and having a M.W. of 300 to 20,000, a polyisocyanate, and, if desired a chain extending agent and a compound having at least one group reactive with isocyanate groups and which contains at least one sulphuric acid semiester group of formula O-SO 3 M, where M is an alkali metal atom, ammonium or amino group, in a quantity such that the proportion by weight of the group O-SO 3 <SP>(-)</SP> amounts to 0À05 to 8% by weight of the polyurethane. The dispersion may be formed (a) by first forming an isocyanate terminated prepolymer which is reacted in an organic solvent with the compound containing the O-SO 3 M group followed by the addition of water and removal of the organic solvent or (b) by adding the prepolymer solution to an aqueous solution of the compound containing the O-SO 3 M group or vice versa. Cross-linked polyurethanes are obtained by first making the aqueous dispersions alkaline, partly drying them in a shaping process and then subjecting them to a heat treatment. During the heating under alkaline conditions the sulphate groups are split off and the polyurethanes cross-linked. Conventional, high molecular weight active hydrogen-containing polymers, polyisocyanates and chain extending agents may be used. The compound containing the O-SO 3 M grouping is suitably derived from such compounds as aminoethanolsulphuric acid, imino-bis-ethanolsulphuric acid, ethylene-bis-aminoethanol sulphuric acid, aminopropanol sulphuric acid, hexamethylene diamine-N,N<SP>1</SP>-diethanolsulphuric acid and hexamethylene-diaminemonoethanol sulphuric acid.
