Title: Method and apparatus for producing glossy coated paper products
IPC: D21G9/00
Filed: 1959-11-03
Abstract: <FORM:0932797/IV(a)/1> A method of continuously producing a smooth, glossy coating on a web 2 comprises applying molten thermoplastic material to the web, pressing the coated surface against a cold casting member 5, and stripping the web 2 from the member 5, the member 5 having a smooth, glossy plastic layer on its peripheral surface, the layer having an adherence with the coated surface defined by a release value of 2 to 20 gms of force for a strip of the coated web 4 inches wide and at a temperature in the range 32 DEG  to 70 DEG F. Plastic materials mentioned are:- polyurethane, polystyrene, polyacrylate and methacrylate, polyvinyl acetol, alkyd urea and alkyd melamine resins.  The material to be coated may be in the form of cut sheets or a continuous web 2 and may be of paper, cellulose acetate, metal foil, e.g. aluminium or tin, or a paper and paper board laminate, and the coating material, which is applied to both sides of the web 2 by rolls 1, may be paraffin wax, micro-crystalline wax, polyethylene, polypropylene, polyterpenes, or mixtures thereof.  In one embodiment, the coated web passes under a heated steel polishing roll 3 and over a rubber roll 4 which is heated, e.g. to 300 DEG F. and which is urged against a roll 5.  The web passes in contact with the roll 5, which is brine-cooled, and through a bath 7 of water, brine, or ethyl alcohol at 32 DEG  to 70 DEG F.  The bath 7 may contain minor amounts of an additive, e.g. a wetting agent, or a glycol or alcohol, and is preferably at a slightly lower temperature than the roll 5.  A soft rubber roll 6 peels the web from the roll 5, and the web may traverse further chilling rolls.  In another embodiment, the web is coated on one surface by a heated steel transfer roll which has a multiplicity of closely spaced recesses and which delivers a uniform wax coating to the web, the roll having a doctor blade. The web continues to the cold roll as before, where air jets may assist in cooling.  Instead of a roll, an endless belt may be employed as the casting member. Specifications 887,932, 896,142 and 917,106 are referred to. Reference has been directed by the Comptroller to Specification 794,460.

Abstract: 998,335. Change-speed control. HUMBER Ltd., and S. J. HARPER. Oct. 4, 1963 [Oct. 5, 1962], No. 37781/62. Heading F2D. In order to avoid transmitting movements of a gear-box which is resiliently mounted on a vehicle body to a manual control lever which is mounted on the vehicle body and which moves to successive stations along a single slot or quadrant, a mechanical linkage between the lever and the gear-box is disconnected from the lever when the lever is at one of its stations and is connected to the lever when the lever is between stations. As shown, a manual control lever 16 is movable along a slot 17 to a number of stations defined by notches 21; when the lever is engaged in a notch 21 a pin 15 thereon is clear of a slot 20 in a crank 11 which forms part of a linkage connecting the lever to the gear-box. When the lever 16 is moved clear of notch 21 into the slot 17 the pin 15 engages the slot 20 so that movement of the lever 16 along the slot 17 pivots the crank 11 about an axis 14. Spring detent means may hold the linkage in position when disconnected from the lever 16. The end of pin 15 is tapered to enable the pin to enter the slot despite misalignment of the slot and pin due to vibration of the crank 11 caused by gear-box movements.

Filed: 1968-08-08
Abstract: 1286452 Impedance measuring bridge CULTON INSTRUMENTS Ltd 7 Nov 1969 [8 Aug 1968] 37969/68 Heading G1U An impedance measuring bridge comprises a series circuit fed from A.C. source V and including a reference impedance Zs and unknown impedance Zu, and a transformer having a winding W2 connected via a galvanometer G1 across the unknown Zu, a winding W1 connected via galvanometer G2 across the reference Zs and a third winding W3 connected across the supply via a variable impedance Z. The winding W3 supplies the current to magnetize the transformer and its control impedance Z is adjusted for null reading in galvanometer G2. The tap on winding W2 is then adjusted for a null in galvanometer G1, the adjustments being repeated until both meters read zero. The ratio of the turns on transformer windings W1, W2 then gives the ratio between unknown and reference impedances and since the current in the W1 and W2 winding circuits is zero the contact and lead resistances R1-R4 can be ignored. For automatic operation galvanometer G2 can be replaced by a high gain amplifier A2 which controls the excitation of the third transformer winding directly in such a manner as to reduce the current in the Zs, W1 circuit to zero and a second high gain amplifier A1 can replace galvanometer G1 and drive the tap control on winding W2 for zero current in the Zu, W2 circuit. Bridge arrangements are shown and described for measuring resistance, capacitance, inductance, the series inductance of a resistor, tangent delta and the equivalent series resistance of a capacitor or inductor.

[Also in Divisions B5 and F1] Apparatus for producing the screw spindles of single-spindle screw pumps from seamless tubes, steel, non-ferrous metals or stainless or plastics materials, comprises a base-plate 20, Fig. 3, secured to a body member 21 having a recess 21 and conical bore 23 which co-operates with shaping-jaws 27 made in three parts urged apart by springs 36, Fig. 4. The shaping-jaws have a tapered helical cavity 28 and are resiliently supported on, e.g. a rubber pad 24 and pressure plate 25. Seamless tube is gradually fed from above and upward pressure applied to the base-plate 20 whence the jaws 27 move radially inwards. As soon as the pressure exerted by the press falls away the upward pressure is released and hence the radial pressure on the jaws. The tube is then fed axially forward and the upward pressure operation repeated. In a modification, the jaws 27 and the bore 23 are tapered with the smaller diameter at the top and in lieu of the rubber pad a helical spring is used. The pressure plate 32 shown in Fig. 3, is then unnecessary. In another modification, Fig. 6 (not shown), the tapered bore 23 and tapered outer surface of the jaws are replaced by wedge surfaces, cams or eccentrics and the jaws moved axially and radially by levers. The apparatus may also include a polishing device to improve the surface finish of the screws.
