Title: Improvements in or relating to coil winding machines
IPC: H01F41/08
Filed: 1953-09-29
Abstract: 738,125. Winding toroidal coils. ONISKO, J., and WATSON, J. R. Sept. 29, 1953 [Oct. 10. 1952], No. 26711/53. Class 83 (4). In a toroidal core winding-machine in which an annular bobbin is rotated in the same direction when being wound with a supply of wire as when winding the wire on to the core the wire is loosely looped around the core during one part of each revolution of the bobbin and is tightened during the remainder of each revolution. The wire in passing from the bobbin 42 to the coil C is guided between a pair of discshaped plates 54, 62, the opposed surfaces of which lie within the bobbin 42. The bobbin is a U-sectioned split ring having one flange supported on rollers 34, 36, 20, the last of which is driven by an electric motor 24 and is journalled in a spring-loaded lever 14 to permit removal of the bobbin. The wire passes over the other flange and between the adjustably mounted guide plates 54, 62 to the core C. The tension of the wire is controlled by a semi-circular strip 78 which presses against the other flange of the bobbin with a force determined by the setting of screws 84 in the guide plate 62 and by a spring-loaded pad 88 which controls the wire when the latter is being looped through the core. In a modification the strip 78 is replaced by an arcuate spring-loaded pad bearing against the guide plate 54.

Patent GB-751934-A (GB)
Title: Improvements in or relating to the copolymerisation of a 2-aryl-alkene-1 and an alpha, beta-olefinic aldehyde
Filed: 1954-09-20
Abstract: An alpha-beta olefinic aldehyde is copolymerized with a 2-arylalkene-1 containing at least three carbon atoms in the alkene group by heating a liquid mixture of the monomers at 50 DEG  to 200 DEG  C., preferably 80 DEG  to 150 DEG  C.  The aldehyde may be acrolein or 2-methyl, 2-ethyl, 2-isopropyl, 2-isobutyl, 2-neopentyl, 2-octyl or 2-phenyl propenal.  The hydrocarbon may be 2-phenyl-propene, -butene-1, -pentene-1, -3-methyl-butene-1, -octene-1 or -octadecene-1, 2 - (4 - methylphenyl) propene - 1, 2 - (2 - isopropylphenyl) butene-1, 2-(4-phenyl-phenylheptene-1) heptene-1, 2-(2,4-dimethyl phenyl) propene-1, 2-(2,4,6-trimethylphenyl) propene-1, or 2-naphthenyl-propene-1. Copolymerization may be effected in the presence of a peroxy catalyst such as benzoyl, acetyl, lauroyl or ditertiary-butyl peroxide or tertiary-butyl hydroperoxide.  The copolymers are soluble in acetone, benzene, toluene, dioxane, chloroform and pyridine, and may be used in combination with nitrocellulose, polyvinyl chloride-acetate and varnish oils in the production of films and for moulding.  The copolymers will undergo further reaction in the following ways: (a) hydrogenation to form polyhydric alcohols by reduction of the aldehyde groups.  These polyhydric alcohols may be mixed with heat-convertible urea-formaldehyde or melamine-formaldehyde resins and baked as a film to form surface coatings; they may be esterified with polycarboxylic acids to form new alkyd resins, or with unsaturated fatty acids, such as are obtainable from soybean oil, dehydrated castor oil and linseed oil to form synthetic drying oils; (b) oxidation to obtain resinous polycarboxylic acids which may be esterified with alcohols to give esters or neutralized with ammonia and/or soda to give salts useful as soil conditioners; (c) reaction with mercaptans to form polymercaptals; (d) reaction with hydroxylamine to form polyoximes; (e) reaction with formaldehyde, ammonia, amines, phenols, urea or melamine to give modified resins.

Title: Photographic camera shutter
IPC: G03B9/08
Filed: 1953-10-02
Abstract: 780,318. Photographic pivoted blade everset shutters. AGFA CAMERAWERK AKT.-GES. Oct. 2, 1953 [Oct. 4, 1952], No. 27162/53. Class 98(1) In an everset pivoted blade shutter, the trigger and master member are adapted so that, after movement of the trigger to a position where the shutter is set, as an alternative to continuance of said movement in the same direction to effect exposure, by release of the trigger it can return to its rest position, and simultaneously bring the master member out of operative engagement with the shutter blade operating means, allowing the master member to return to the rest position without making an exposure. As shown, on, pressing the trigger 1 a lever 3 pivoted thereon at 4 and spring-urged anti-clockwise towards the centre of the shutter is caused to move with the trigger anti-clockwise around the shutter aper-, ture and by a notch 3b thereon engaging a rectangular-section stud 8 carries with it the master member consisting of a resilient extension 6 on a ring 7 rotatably mounted about the shutter aperture. During this movement the nose 6b on a cranked portion 6a of the resilient extension 6 moves over the end 1a of the trigger 1 and rides up and over a cam 12 on the trigger. When this is completed a segmental nose 3a on the lever 3 engages a stud 11 fixed on the shutter base plate 10 so that the lever turns clockwise and disengages from the stud 8 on the extension 6. This is thus freed to be rotated clockwise by the tensioned spring 9 when a cam 15 on the extension 6 engages a a pin 13 connecting by means of a slot a pair of oivoted blades 16 to open the shutter. When the cam 15 has moved past the pin 13 so that the extension again overlies it due to the cranked portion 6a on the extension 6, the pin is returned by a spring 17 to close the shutter, so that on release of the trigger the shutter is restored to the position shown.

Title: Ultrasonic transducer assembly
IPC: A61B8/00
Filed: 1970-06-05
Abstract: 1,269,869. Ultrasonic transducers; ultrasonic lenses. F. HOFFMANN LA ROCHE & CO. A.G. 5 June, 1970 [5 June, 1969], No. 27181/70. Headings H4J and H4X. [Also in Division H1] An ultrasonic transducer assembly, e.g. for investigating human arterial wall motion using the Doppler effect, has an elongate preset curved printed circuit board 24 (Fig. 3) supporting ultrasonic transducer units 25 to 29 along its longitudinal axis. The preset curved board 24 permits securing of the assembly to an arm by an inflatable cuff without appreciably changing the curvature of the assembly. Piezo-electric elements 31, e.g. of lead zirconate titanate, are supported by individual fibreglass boards 32 on the curved board 24. Board 24 is of copper clad fibre-glass. A lens 30 (Fig. 2) is secured to each element 31. A flexible potting compound 33 leaves the lenses 30 exposed but helps to maintain the curved configuration. In use, a coupling paste fills the recesses 35 between adjacent transducer units 25 to 29. A cable 34 (Fig. 4) has shielded wires 36, 37 connected to board 24. A signal line 38 on the board 24 is connected to receiver units 25, 27, 29 and a signal line 39 is connected to transmitter units 26, 28. Earth lines 41 and 43 on each side of the board 24 are connected by a lead 42, 44 respectively. Alternatively, common transmitter and receiver units may be used in conjunction with a single signal line (not shown), its shield being connected to earth line 43. The lines 38, 39 are R.F. shielded by members (45, 46) Fig. 6 (not shown) of fibre-glass (47) clad with copper (48) and bonded to the board 24. The transducer assembly is secured by an inflatable cuff to a patient's arm. Lens.-The lenses 30 are insulators and have similar physical characteristics to those of the elements 31 to reduce the effects of external stress and strain including thermal expansion. A high ultrasonic velocity in the lens with respect to body tissue is required for maximum beam spread. The lenses are of ceramic or glass, preferably alumina. The lens may be convex across its width and flat or concave in the length direction. The lens may have a depressed face and concave and convex curvatures (Fig. 8). A rectangular cavity (56) Fig. 9 (not shown) houses the piezo-electric element 57. The element 57 may be secured to the circuit board 24 by silicone or epoxy insulation (58). An electric contact (61) from the element 57 passes through an aperture in the board 24 to connect with the rear of the board.

Title: Method and apparatus for making lenses and like optical devices
IPC: G02B1/02
Filed: 1945-10-19
Abstract: 603,381. Forming crystal optical devices by solvent action. FARNSWORTH TELEVISION & RADIO CORPORATION. Oct. 19, 1945, No. 27497. Convention date, Oct. 14, 1944. [Class 124] In a method of forming lenses and like optical devices from soluble materials, a protective coating is formed periodically on the surface of a soluble blank which is brought into contact with a mould which is the negative of the device to be formed and which removes the protective covering from the high spots of the blank, the blank and mould are then separated and the exposed portions of the blank are subjected to the action of a solvent. As shown, a sodium chloride crystal blank 5, which may be partly shaped, is supported in a holder 3 attached by a spider 2 to a container 1 for water. A piston 10 supports, above the blank, a mould 19 which may be kept cold by a refrigerating mixture 17A in a container 16 to which the mould is attached, and, below the blank, a quantity of Wood's metal 22 which may be kept molten by an induction coil 24 so that when the piston is raised, e.g. by a cam 14, the Wood's metal mav flow over the surface of the blank. On lowering the piston, a thin layer 6 of metal remains on the surface of the blank so that when the mould 19 is pressed on to the blank the metal is removed from those points where the mould touches and, due to the coldness of the mould, it is solidified. On raising the piston again, water is allowed to flow over the blank and dissolve a small quantity of the exposed sodium chloride. This cycle is continued until the blank assumes the shape of the mould, at which time the downward movement of the mould is limited by the adjustable stops 20A. The mould may have the form of a segment of the device, Fig. 6 (not shown). In a modification, Fig. 5 (not shown), the blank holder may be moved into contact with the mould and then into the solvent. The protective covering may be wax which is melted by a hot air blast, or may be an amalgam, e.g. silver amalgam made molten by the addition of mercury.
Patent GB-464116-A (GB)
Title: Improvements in the manufacture of viscose rayon
IPC: D01F11/02
Filed: 1935-10-04
Abstract: Sulphur is removed from viscose rayon by adding to the spinning bath or to a treating bath, at any convenient stage of the manufacture, a quaternary phosphonium or ternary sulphonium salt, at least one radical of which consists of a long or branched carbon chain containing not less than eight carbon atoms.  The process may be carried out under neutral, acid, or mild alkaline conditions, or it may be used in conjunction with the usual sodium sulphide or other desulphurizing bath.  In this latter case it enables a lower concentration of the sulphide than usual to be used and it may be carried out at a lower temperature.  The phosphonium or sulphonium salt may be added to an acid coagulating bath or to a subsequent washing bath, or to a bath in which the dried or undried crude undesulphurized filaments or fabrics are treated.  In view of their fatty nature, the sulphonium or phosphonium salts lubricate the filaments and facilitate winding. Dimethyl hexadecyl sulphonium methyl sulphate, benzyl ethyl dodecyl sulphonium chloride, and stearamido benzyl dimethyl sulphonium chloride are suitable sulphonium salts.  Cetyl triethyl phosphonium bromide, and dodecyl triethyl phosphonium bromide are suitable phosphonium salts.  In an example, viscose solution is spun into a coagulating bath containing dilute sulphuric acid, sodium sulphate, and 1,5 per cent of dimethyl hexadecyl sulphonium methyl sulphate.
