Title: Process and apparatus for covering wires with plastic material in two or more helically arranged colours, and wire when so covered
IPC: B29C48/19
Filed: 1957-03-15
Abstract: A process for coating a wire with a plastic sheath helically striped in more than one colour comprises passing the wire through an extruding nozzle substantially without relative rotation of wire and nozzle, so that a sheath of plastic material is applied in parallel longitudinal coloured stripes, and subsequently twisting the coated wire to set the stripes permanently in a helical twist.  The twisting may be effected as the wire emerges from the extruding nozzle by twisting the drum on to which it is coiled, or it may be effected after coiling by re-coiling it on to a further drum whilst the latter is twisted about an axis perpendicular to that of its rotation.

Filed: 1942-06-24
Abstract: 566,321. Spectacles. BOLLE, L., and NATIONALE SOC. ANON. June 24, 1942, No. 8673. [Class 97 (i)] In a spectacle frame in which the sides have straight portions 2 with plane inner faces, and are so hinged to the upper part of the front 1 that when opened the centre lines of these portions make an acute angle with the plane of the front, the pivotal axis 5 of each hinge is located in planes parallel to the front and to the inner face of the portion 2 of the side, and is inclined relatively to the plane of symmetry c of the frame and to a plane b perpendicular to the straight portion of the side. As shown, the angle i of each hinge axis to the vertical is substantially equal to the forward inclination i<1> of the front relatively to the plane b<1>. The hinges may be positioned so that, when folded, the portions 2 of the sides either overlap or lie side by side as in Fig. 6. In either case the hinge of the side first folded may be partly embedded in the frame, the wings of the other being spaced to enable the second side to fold over the first. The ordinary hinges shown may be replaced by hinges having their wings at an angle to the pivotal axis so as to lie horizontally on the front and side members of the frame. One hinge part may be formed by shaping the end of a metallic reinforcing member extending within the side member.

Title: Improvements in or relating to boot or shoe lasting machines
IPC: A43D21/12
Filed: 1938-03-22
Abstract: 512,921. Lasting-machines. BRITISH UNITED SHOE MACHINERY CO., Ltd., BARKER, W. A., and LANE, H. March 22, 1938, No. 8711. [Class 17 (i)] Relates to wiper extensions of the kind described in Specification 453,706, wherein the extensions can yield away from each other when they contact with each other, and away from the work when they contact with an insole lip or other raised portion of the work, and consists' in modified constructions wherein the first mentioned yield cannot occur prematurely, and the second yield is about a virtual axis substantially at the meeting line of the. wiping faces of the main wiper and the extension and parallel to the last bottom. The extension has a portion 7 fixedly secured to the forward end of the main wiper by a screw and a dowel pin 11. This portion carries a plate 21 having formed on it an arcuate guide 23 engaging a corresponding recess in a member 25, which member can thus swing about a virtual centre near the work engaging face of the extension, near the meeting parts of the main wiper and the extension, and parallel with the face. The member 25 is bored to receive a pin 35 integral with a member having a wiping surface 37. A spring 45 urges the wiping surface inwardly of the edge of the shoe, yield being prevented by a pawl 53, pivoted at 55, until near the end of the closing movement of the wipers. Near this end, arms 61 of the two pawls contact with each other and allow swing about the pivot 35, to prevent damage to the machine. Should the part 37 foul the insole lip or upwardly curved portions of the waist of the shoe, the work engaging surface of the extension yields about its virtual axis against a spring 31. In a modification, the lateral yield is provided by a sliding, instead of a pivoted member, and the pawl is substituted by a locking roller urged by a spring into wedging engagement with relatively inclined surfaces. The rollers are each freed by a pin, the two pins being in alignment in the closed position of the wipers. Specifications 391,451 and 440,329 also are referred to.

Title: Liquid sensing and indicating device
Inventor: GOULD WILLIAM JOSEPH
IPC: G01P13/00
Filed: 1969-02-18
Abstract: 1,248,084. Liquid level detection. SOUTHERN INDUSTRIES (CROYDON) Ltd. Jan. 2, 1970 [Feb. 18, 1969], No. 8752/69. Heading G1H. A device for detecting the presence or absence of electrically conductive liquid comprises a pair of spaced probes 15, 16 which are immersed when the liquid is present, a first transistor T1 having the probes connected in its base circuit so that it is conductive when the liquid is present and substantially non-conductive when the liquid is absent, and further circuitry which includes a lamp arranged to flash in the presence of liquid and to be extinguished in the absence of liquid. As described, beer in a bore (12) Fig. 1 (not shown) of a sensing unit (11) maintains a low electrical resistance between probes 15, 16. This low resistance causes transistor T1 to pass on current between a positive line 28 and a negative line 29, no current then passes through the Darlington pair of transistors T2, T3 to line 30. In the absence of beer, the resistance between probes 15, 16 is very high, T1 no longer conducts and the potential at the collector of T1 is sufficient to make T3 conduct and thus T2 to conduct and bring line 30 to the potential of line 28. Transistors T4 and T5 are connected in an astable multi-vibrator circuit which operates when line 30 is at this potential, and causes a bulb to flash when connected across terminals 31.

Abstract: 731,823. Rotary tilting furnaces. DEMAC AKT.-GES:, and KRUS, A. April 4, 1952 [May 26, 1951], No. 8760/52. Class 51 (2). In a rotary tilting furnace, the rotary drum 1 is mounted on a frame comprising segments 4 provided with teeth engaging other teeth 6 on horizontal tracks 5, said frame being provided with projections 7, 8 and 9, over which passes a chain 10 secured to the projections 8 and engaging hoisting gear 11. The radius of curvature of the segments 4 and the position of the tilting axis relative to the axis of the furnace are so chosen that it is not necessary to move the ladle 12 into which the furnace discharges. Axial displacement of the drum 1 is prevented by rollers 3 and the part 5a of the track on which the segments rest is rotatable about a vertical axis. In a modified tilting arrangement, Fig. 2 (not shown), the piston rod of a vertically mounted pivoted hydraulic cylinder engages, by means of a roller, one end or the other of an arcuate slot formed in the support frame, thus tilting the furnace in either direction. The roller is positioned in the slot by the pistons of horizontally mounted hydraulic cylinders.

Title: Manufacture of triphenylmethane-azo-dyestuffs
IPC: C09B11/20
Filed: 1924-04-07
Abstract: Azotriphenylmethane dyes which dye wool from an acid bath in yellow shades changed to fast green by afterchroming are prepared by diazotizing a triarylmethane compound of the general formula <FORM:0234950/2/1> (in which R, R represent the same or different alkyl or aralkyl residues) and coupling with a 1-aryl-5-pyrazolone derived from an aminosalicylic acid or a homologue or derivative thereof such as an aminocresotinic acid, an aminosulphosalicylic acid or a chloraminosalicylic acid.  In an example p-amino-o-sulpho-tetramethyl-pp-diaminotriphenylmethane is diazotized and coupled with 1-(41-oxy-31-carboxy)-phenyl-3-methyl-5-pyrazolone. Other pyrazolones mentioned are 1-(41-oxy-31-carboxy-51- or 61-methyl)-, and 1-(21-oxy-31-carboxy-51-methyl) - phenyl-3-methyl-5-pyrazolones, and also the corresponding 3-carboxylic acids.  Triarylmethane derivatives of the above general formula are obtained in the known manner either by condensing 3-aminobenzene-1-sulphonic acid with the appropriate hydrol, or by condensing 2-sulpho-4-nitrobenzaldehyde with a tertiary amine and reducing.  1-(21-Oxy - 31-carboxy - 51-methyl)-phenyl - 3-methyl-5-pyrazolone is obtained in the usual way from 2-oxy-3-amino-5-methylbenzoic acid which is itself prepared by nitrating and reducing p-cresotinic acid.

Abstract: 348,293. Reducing surface friction. BULLOCK, R. N., 76, Boyne Road, Lewisham, London. March 19, 1930, No. 8857. [Class 4.] Aircraft, motor cars and other rapidly moving bodies have means for heating the film of air in the neighbourhood of the surface or a part of the surface by exuding or seeping heated air at the surface near the leading end. In an application to an aeroplane, Fig. 9, air passes through a cowling 1 of an air-cooled engine into a series of passages arranged along the sides of the fuselage 4 to the tail unit 6 and to wings 5 through hollow struts 9. A series of louvres or belts of holes 7 is arranged around the body 4 and are connected to the cowling 1 by the air passages. Series of holes also connected to the air supply are arranged at points of great resistance such as the points of junction of the wings and tail surfaces to the body. The body louvres which open from annular passages provide medium size outlets at the nose and of fine size near the point of maximum cross section, again increasing in size from this point to the tail. Rows of louvres 7a, 7b, 7c, Fig. 2, are arranged in the extrados of the wings parallel to the leading edge at distances respectively of <1>/12, <1>/3 and <2>/3 the chord, the width of the louvres being in the proportion 1 : 2 : 3 from front to rear. The intrados covering is similarly louvred but the louvres are arranged at distances of 1/10, 1/5, and ¢ the chord respectively. Figs. 4. 5, 6 illustrate the construction of a wing louvre, Fig. 6 showing sections along lines A<1>, B<1>, C<1>, D<1>.. O<1>, P<1> respectively of Fig. 4. The surfaces of the aircraft may be covered with low heat-conducting materials and those of the body and wings may be provided with series of fine graving lines for holding the warm air to the surface. In a modification the nose of wings, struts and bodies may be provided with a nose cap or cowl for the exudation of warm air. The warm air may be obtained from the engine exhaust or from air passing over the radiator or be heated by electrical means, steam or hot water.

Title: Digital optical modulator
IPC: H03K17/78
Filed: 1968-02-23
Abstract: 1,220,486. Light modulators. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 23 Feb., 1968 [25 Feb., 1967], No. 8909/68. Heading H4F. A digital electro-optic or magneto-optic modulation arrangement comprises at least two separate modulators of different construction and/or different electric or magnetic operating characteristics which are successively passed by the radiation to be modulated, each modulator being individually switchable between two operating points in which the electro-optic or magneto-optic material is subject to different electric or magnetic field strengths. The modulators may comprise Kerr or Pockels cells in which the electro-optic material is nitrobenzene, KDP or KTN, the length of the cells, the spacing of the electrodes of the cells, the voltages applied to the cells, or the lengths and voltages of the cells being varied from cell to cell (Figs. 2-4, not shown). Different lengths of magnetooptic material e.g. YIG, may be subjected to a magnetic field (Figs. 5, not shown). To obtain a more homogeneous polarization of the electrooptic material, dielectric plates of material having a small dielectric constant compared to the dielectric constant of the electro-optic material are interposed between adjacent modulators the refractive index of the two materials being substantially equal (Fig. 8, not shown). To produce a system in which the intensity of a radiation beam may be varied in logarithmically equidistant steps, the dielectric plates of Fig. 8 are arranged to comprise plane polarizers or are replaced by plane polarizers (e.g. Nicol prisms or multilayer dielectrics one layer of which comprises a plane polarizer) having the same direction of polarization (Fig. 9, not shown), the direction of polarization being preferably at 45 degrees to the direction of the electric field in the modulators. Each modulator thus changes the intensity of the radiation beam by a factor F i  which is less than one. The resulting intensity of the beam after passage through the entire modulator thus equals I = I 0 F 1 F 2 F 3  . . . F n  or 1nI= 1nI 0 + 1 n F 1 + 1nF 2  + .... A binary system having logarithmically equidistant stages is obtained, for example, by making F 1  = 0À5, F 2  = 0À5<SP>2</SP>, . . . F i  = 0À5<SP>i</SP>.
