Title: Improvements in and relating to clothes pegs, paper clips and the like
IPC: B42F1/08
Filed: 1945-03-02
Abstract: 585,559. Wire clips. NICOLSON, T. March 2, 1945, No. 5200. [Class 44] A clothes peg, paper clip, or the like, of wire, partly or wholly corrugated, and preferably of spring metal, is coiled to form a main circle or ellipse 1,-on each side of which a semi-circle or semi-ellipse 2 is formed, the ends of the wire projecting normally from the circumference forming legs 3 which are splayed apart and have loops at their extremities to form flat finger grips 4. When these grips 4 are pressed together the lower parts of the train circle and semicircles separate to allow the insertion of the clothes and line ; when pressure is removed the resilience of the wire makes the clip close. The half-loops 2 may be coiled to form secondary complete loops, or may be straight, curved, or zigzag. Towards the ends of the half-loops 2 the two ends of the wire may approach one another in a straight line and then form legs. In a modification, suitable for gripping thin articles, e.g., sheets of paper, instead of two half-loops, only one is formed, and the other end of the wire extends diametrically across the main circle (or along the major axis of the main ellipse) and terminates in the finger grip spaced away from the other grip.

Title: Improvements in or relating to electromagnetic measuring apparatus
IPC: G01D5/12
Filed: 1936-02-21
Abstract: 472,313. Magnetic measurements. MUIR, N. S. Feb. 21, 1936, No. 5217. [Class 37] Electromagnetic apparatus for measuring a selected component of relative angular or translational movement between two members, and of the kind wherein the reluctance of a circuit is varied, has three or more magnetic systems symmetrically arranged so that the changes in reluctance of the several systems produced by the selected component are additive, whereas changes due to other components of movement balance out. Magnetic systems with circumferential and radial airgaps, or with airgaps at right-angles are employed, the coil systems being symmetrically arranged on the relatively movable parts. The drive from an engine to an airscrew A<2> takes place through a rim B<2> and boss B connected by radial spoke springs B <1>. The boss B carries an annular magnetic plate D formed with symmetrically 'located 'poles D<3>, D', co-operating with poles D', D<8> mounted on an annular plate E carried by the rim B<2>, the magnetic systems thus comprising a series of circumferential airgaps F, F<1> and a series of radial airgaps F<2> located between them. The initial lengths of the airgaps are chosen so that the flux densities do not approach saturation at the greatest relative movement between the magnetic systems. Primary and secondary coils E<1>, E<2>, E<3>, are connected through slip-rings H... H<3>, the primaries in series to generator G, and the secondaries in pairs in series opposition. The coils are connected through a dynamometer G<1> to a receiver provided with similar symmetrically arranged magnetic systems. Voltages induced by radial vibrations in the magnetic systems are balanced out, and those induced by variation in the circumferential gaps are indicated on the dynamometer, the amount of angular movement of the receiver necessary to restore the null reading being a measure of the quantity desired. Instead of a dynamometer type instrument, oxide rectifiers with a continuouscurrent meter can be employed, and the supply source may comprise a. permanent magnet alternator, valve oscillator, or intermittent direct current. Stops are provided for limiting the movement of the radial spoke springs. The magnetic systems can be employed with quill shaft drives from the engine to the airscrew. Fig. 10 shows a construction for measuring direct tension or compression, for example, as in a thrustmeter, the rim O<2> and hub O<1> of the transmission being capable of relative movement parallel with the axis of shaft A<8> and the magnetic systems having airgaps P<1>-P<2> with relative lateral movement. In Fig. 11, the airgaps T, T<1> are inclined and are magnetized by primary and secondary coil systems, the relative movement of the parts giving rise to gap variations in two directions at right-angles, one or other movement being responsive to the non-selected component and being balanced out. Specification 472,317 is referred to.

Title: Polyurethane foams having increased density and process therefor
Inventor: ZOCCO NATALE CARMEN
IPC: C08J9/00
Filed: 1969-01-30
Abstract: 1,240,649. Densified polyurethane foams. OLIN CORP. 18 April, 1969 [18 Jan., 1968; 30 Jan., 1969], Nos. 37983/67 and 5231/69. Heading B5A. [Also in Division C3] A flexible densified polyurethane foam having a density of 1À5 to 15 lb./cu.ft. is prepared by allowing a polyurethane foam-forming reaction mixture having a free rise density of 0À8 to 4 lb./cu.ft. to rise, forming a partially cured cellular material, applying a compressive force after 0 to 10 minutes after completion of rise and reducing the volume to 2/3 to 1/10 of its original volume, and removing the force and completing the cure, with the proviso that when the period of time between completion of rise. and application of compressive force is from 0 to 2À5 minutes the material is kept at 45 to 400 F., when the period is 2À5 to 5 minutes the temperature is 45 to 200 F., and when it is 5 to 10 minutes the temperature is 45 to 110 F. The densified foam may have top and/or bottom layers of less dense flexible foam which may be removed by cutting &c. The formation of such layers is decreased by the use of fluorine-containing foaming agents. Conventional mixtures based on polyether- and polyester-polyols are used. In a modification, the process may be applied on a backing, e.g. for floor covering, by pouring the reaction mixture on to a continuous moving length of backing and compressing the partially cured material. A large number of uses, is specified.

Title: Coated pharmaceutical granules and tablets thereof
Inventor: ASHWORTH FRANK
IPC: A61K9/50
Filed: 1958-02-18
Abstract: Prolonged acting granules of a medicament consist of granules of the medicament coated with a composition comprising a non-toxic, impermeable cellulose ether or cellulose ester which is very sparingly soluble in the digestive fluids of the alimentary tract and a substance which is readily soluble in the digestive fluids of the alimentary tract and is present as 5 to 30% by weight of the coating. The granules of the medicament are prepared in a conventional manner. The medicament may be mixed with a diluent such as sucrose or lactose before granulating.  The granules are coated by rotating them in a coating pan and spraying on to them a solution in a volatile solvent, e.g. acetone or alcohol of the film-forming substance and the readily soluble substance.  The granules are used as such or put up into capsules or caskets or compressed into tablets.  They may be mixed with uncoated granules or an inert substance such as lactose, sucrose, glucose or dicalcium phosphate and then compressed into tablets. In examples: (a) granules of acetyl-salicylic acid are coated with ethyl cellulose and polyethylene glycol 1000 and a mix of coated and uncoated granules tabletted; (b) granules of ephedrine hydrochloride, sodium chloride and sucrose are coated with cellulose acetate, polyethylene glycol 1000 and polyoxy-ethylene sorbitan monolaurate, and a mixture of coated and uncoated granules are tabletted; (c) granules of acetylsalicylic acid are coated with ethyl cellulose and dioctyl sodium sulpho-succinate and granules of p-ethoxyacetanilide and methyltheobromine are likewise coated, the granules mixed and tabletted; (d) acetyl-salicylic acid, p-ethoxyacetanilide and methyl-theobromine are coated as in (c), mixed with uncoated granules and tabletted.

Title: An improved power press
IPC: B30B15/00
Filed: 1957-02-15
Abstract: 862,154. Mechanical presses. GOLDING, W. F. Feb. 6, 1958 [Feb. 15, 1957], No. 5272/57. Class 87(2). [Also in Group XXII] The reciprocating platen 3 of a press is actuated by toggles 4 in each of which the lower link 6 is pivoted to a member 8 connected to the base 1 by screw means for varying the distance between the member 8 and the base 1 and thereby the daylight between the platens 2, 3. The screw means comprise a screw threaded member (or members) 9 secured to the member 8 and a cylindrical nut 10 housed in a bore 12 and having on its periphery worm-wheel teeth 25 engaged by a worm 26. In the arrangement shown, in which the platen 3 is supported at each corner by a toggle, simultaneous adjustment is achieved by the worms on one side being on a common shaft 27 and those on the other side on a common shaft 28 which is chain-driven from the shaft 27 when this is turned by a hand wheel 30. The turning of the nuts 10 is facilitated by each resting on a ball or roller thrust bearing 24 when the press is not applying the working pressure. The bearing 24 is interposed between the lower face 13 of the nut 10 and the head of a sleeve member 16 abutted by a spring 21 which rests on an adjustable support 22. The springs 21 are adjusted so that their combined strength can lift the platen 3 when the press is idle, but when the press is operated the working pressure between the platens compresses the springs 21 and the face 13 seats on the bottom face 14 of the bore 12, which takes the thrust. Alternatively a ball or roller bearing between the faces 13, 14 may take the load at all times.

Filed: 1936-02-21
Abstract: 470,785. Television. BAIRD TELEVISION, Ltd., and JONES, V. A. Feb. 21, 1936, No. 5278. [Class 40 (iii)] In a television transmitter employing an electron camera in which an electronic image is adapted to be traversed over an aperture through which electrons pass to yield an image signal, means are provided for rendering the camera inoperative during flyback periods. For this purpose, a negative impulse may be applied during each such period to an apertured shield 3 surrounding the anode 9, Fig. 1, or to an additional electrode which is situated outside this shield or enclosed in an extension of it. In a modification, Fig. 2, the negative pulses are applied during the flyback periods to a valve 8 through which the anode 9 is connected to the positive pole of a source of potential 7, thereby effectively disconnecting the anode during these periods. According to the Provisional Specification, the invention may be applied to the electron camera described in Specification 461,197.

Title: Improvements relating to loudspeakers
Inventor: RACKHAM RONALD HASTINGS
IPC: H04R1/40
Filed: 1957-02-15
Abstract: 831,211. Loud-speakers. TANNOY Ltd. May 6, 1958 [Feb. 15, 1957], No. 5281/57. Class 40 (4) In a loud-speaker assembly which constitutes a line source, successive loud-speakers face in opposite directions. As shown, the six cone loud-speakers 1-6 are mounted on a common baffleboard 8, with loud-speakers 1, 3, 5 facing to the right, and 2, 4, 6 to the left. A single pair of terminals on the framework 9 may be connected to all the loudspeakers, the connections to 1, 3, 5 being reversed with respect to those to 2, 4, 6 so that the diaphragms of all the loud-speakers will move in the same direction at the same time. This arrangement of loud-speakers compensates for the deficiency in the higher frequencies of the sound rearwardly directed from a cone loud-speaker. If desired, some of the loudspeakers, e.g. 5 and 6, may have elliptical cones and thus produce an output rich in the higher frequencies.

Title: Improvements in or relating to machines suitable for use in inserting headed fasteners in workpieces
IPC: A43D75/00
Filed: 1941-04-25
Abstract: 550,831. Fastener-inserting machines. BRITISH UNITED SHOE MACHINERY CO., Ltd., LANE, H., and KEALL, F. B. April 25, 1941, No. 5337. Addition 539,458. [Class 89 (iii)] The machine described in the parent Specification is modified, the air current feeding the headed fastener along its passage comprising a current at low pressure continuing for an appreciable time supplemented at an early stage by a puff at higher pressure. A compressor pump 63 is driven by a friction disc 65 adapted.to engage a pulley 69 on the tensioning of a cable passing over pulleys 83 by a cam-actuated lever 82. This pump delivers air at one or two pounds p.s.i. by pipe to the tack delivery tubes 15. A cylinder 25 houses mechanism of the kind described in Specification 150,424, [Class 17, (i)], for producing a momentary puff of air at a higher pressure through an outlet 33. The lever 82 turns a shaft 87 on which is pivoted an expander bracket comprising three slides 99, 101, 103 moved by a pinion on the shaft and geared together by racks and a pair of segments 111. Spring plungers 129, 146 connect these slides with others carrying tackers, the arrangement being that on gauges on the tackers contacting with the shoe the V-shaped heads of the plungers are forced out of their recesses and the tack drivers 121, 135 are released to drive the tacks. Springs 155 prevent rebound of the tackers from the shoe. The pump 63 is stopped just prior to the actual driving of the tacks, and the next gang of tacks are fed. Specifications 16398/15, [Class 17 (i)], 373,183 and 396,086, also are referred to.

Title: Improvement in process for making a beater furnish
IPC: D21H17/48
Filed: 1934-02-19
Abstract: Material suitable for furnishing a beater is prepared by adding to a moist mass of fibre such as sulphate, sulphite or soda pulp, rag stock, asbestos or textile fibres, ingredients capable of forming a resin under heat in the presence of a catalyst, heating the mixture while maintaining mechanical mixing and then rapidly dropping the temperature to stop the reaction while the resin is still in a heat fusible state preferably by adding cold water to the mixture. Suitable ingredients include a solution of formaldehyde, a phenolic body and an ammonia catalyst with or without an alkali salt of a weak acid.  In an example, unbleached sulphite pulp is mixed with water and there is added to the mixture in turn soda ash, cresylic acid, formalin and ammonia and the final mixture heated and then mixed with cold water.  Calcium stearate may be added to the mixture to enable the final product to separate readily from the moulds.  Plasticizers such as dibutyl phthalate may be added.  Paper and boards made from the product may be used in the manufacture of laminated products such as sheets used for punching out small mechanical parts or electrical insulators, for the manufacture of shaped and drawn articles such as trays, in the fabrication of decorated panels used for table tops, interior trim, and imitation wood panelling.

Abstract: 193,863. Kand¾, K. Feb. 25, 1922, [Convention date]. Addition to 176,365. Alternating - current motors; motors, controlling. - A winding for a variable-speed polyphase induction motor of the type described in the parent Specification, i.e. one convertible from Sn-poles for 3-phase to 6n-poles for 4-phase running, as well as 12n-pole for 2-phase running, is adapted to give in addition a 4n-pole 6-phase connection. The coils of the 8n-pole winding spaced apart by 120/n degrees are connected together at one end to a common group lead to form a group of coils and at their other ends to place leads by which the coils of different groups in the same phase are joined together and to one of the 3-phase supply leads. The drawing shows a rotor winding in which n is unity and in which the group and phase leads respectively are formed by sets of slip-rings 1 - - 8 and a - - f. The supply is given by a source F tapped at I, II - - XII of the controller K. The controller has four sets of connectors A, B, C, D for 2, 3, 4 and 6-phase working respectively. The rotor coils are in groups of three spaced at 120‹, such as the coils 8 - - 13, 40 - - 45 and 24 - - 29, shown respectively in dotted, chain and full lines, and these are connected to common group rings, such as the ring 1, at one end. The other ends of the coils are connected to the phase rings a - - f. Half of the coils of any one of the three phases are connected to one ring of that phase, e.g. the adjoining coils 4 - - 9 and 46 - - 3 and the opposite coils 28 - - 33 and 22 - - 27 connected to the ring a of the phase I, V, and the other half are connected to the other ring of the phase, e.g. the coils 10 - - 15, 16 - - 21, 34 - - 3' and 40 - - 45 to the ring d. In position B of the controller, the coils are connected to the 3-phase terminals I, V, IX as an 8-pole winding, the rings 1 - - 8 being disconnected from the supply and forming neutral points. In the position D, the phase rings a - - f are respectively connected to the 6-phase supply points I, III, V, VII, IX, XI giving a 4-pole winding with the rings 1 - - 8 as neutral points disconnected from the supply as before. In position C, the phase rings a - - f are disconnected from the supply and 4-phase power passes from the terminals I, II, IV, VI, VII, VIII, X and XII to the respective group rings 1. 5, 2, 6, 3, 7, 4 and 8, between which the twenty-four coils are distributed evenly as a 4-phase 6-pole winding of six coils per phase. The 12-pole 2-phase arrangement is given in position A which differs from position C only in having the group rings 1 - - 8 connected to the supply terminals in pairs instead of singly. In this case, the pairs of group rings 1 - - 3, 6 - - 8 and '3 - 4 are respectively connected to the 2-phase terminals I, IV, VII and X.
