Filed: 1971-06-04
Abstract: 1366703 Foamed coatings MONSANTO Ltd 12 May 1972 [4 June 1971] 18930/71 Heading B2E [Also in Division D1] A process for the production of a laminate comprises extruding a foamable synthetic thermoplastic resin through a slit die and thence into an aperture defined by a pair of opposed surfaces, one being static and the other the surface of a flexible substrate material carried on a heated driven roller rotating about an axis parallel to the slit so as to cause the substrate material to move in the direction of extrusion, the dimensions of the aperture and the movement of the substrate material being such that the foaming resin remains in contact with both surfaces for at least part of its passage therebetween and such that contact between the resin and the substrate material takes place while the resin is still above its softening point and before foaming of the resin is complete. Preferably, the resin is extruded at from 10 to 80C above the softening point of the resin. The driven roller is preferably heated to a temperature within 10C below the softening point of the resin. Before the thermoplastic resin is completely hardened its surface can be brought into contact with the second roller which may be plain or embossed. Suitable substrate materials are woven cotton or jute scrim. Light-weight woven or non-woven fabrics of natural fibre or from cellulose ester, nylon or acrylic fibre, and paper such as Kraft paper or a thermoplastic film such as PVC, polystyrene or polyethylene film may also be used as a substrate. Suitable thermoplastic resins are polymers or copolymers of ethylene, propylene, butadiene, styrene, vinyl toluene, or alpha-methyl styrene or a substitute monomer such as acrylonitrile, vinyl or vinylidene chloride, vinyl acetate, methyl acrylate, methyl methacrylate or ethyl acrylate. Numerous suitable substrate materials are specified. Numerous suitable drawing agents are also specified.

Title: High frequency coil with variable inductance
IPC: H03H2/00
Filed: 1943-11-16
Abstract: 570,474. Inductances. PATELHOLD PATENTVERWERTUNGS- & ELEKTROHOLDING AKT.-GES. Nov. 16, 1943, No. 19114, Convention date, Dec, 17, 1942. [Class 38 (ii)] [Also in Group X.L] In a high-frequency coil having turns wound in a single layer upon a cylindrical surface, the inductance of which is variable by the axial movement of a. conducting cylinder, the current that flows through the inductance flows through the capacity formed by the sliding cylinder and the coil turns covered by the cylinder. Fig. 1 shows an arrangement in which the inductance of a coil 1 is varied bv the endwise movement of a metal cylinder 2. The end C of the coil is connected to the cylinder, the current being taken from a terminal D. With this arrangement, the screened part 4 of coil 1 has its inductance neutralized, but the part 4 coacts with cylinder 2 to constitute a capacitive Lecher pair. In this arrangement the capacity is reduced when the cylinder 2 moves to the right to increase the inductance. The galvanic connection between coil 1 and cylinder 2 may be omitted, the arrangement then acting as an open-ended Lecher pair. Alternatively, the capacitative connection between the end. C of coil 1 and the cylinder 2 may be improved by the addition of a metal cylinder 5, Fig. 3. In this case, the capacity may be arranged to be constant or to increase with an increase of inductance. A load may be connected between the end C of coil 1 or cylinder 5 and the movable cylinder 2, with or without means for impedance matching. Fig. 6 shows one such arrangement in which a load (not shown) is connected between the movable cylinder 10 and the end C of the coil by means of a concentric line 8, 9. An outer screening cylinder 11 is also included. Fig. 7 shows a tuned output circuit for a valve in which the coil 3, variable by moving cylinder 2, forms a parallel resonant circuit in conjunction with fixed capacity 12, the output being taken from terminals 15, 16. Two arrangements for push-pull connected valves are also described (Figs. 10 and 11, not shown). Fig. 12 shows a tunable coupling circuit in which a variable inductance coil has one layer inside and one layer outside a metal shell 24 which is axially movable to vary the inductance and capacity. A movable metal shell or cylinder may also be provided inside the coil. Fig. 13 shows an arrangement in which the inductance is varied by a screw movement of a. metal cylinder which is formed with a stop 23 at right angles to the wire to give a sharp division between the screened and unscreened parts of the coil. The inner surface of the cylinder is shaped to fit the profile of the turns of the coil and the capacity is increased by using flat wire, The cylinder may be, inside or outside of the coil, or both. The arrangement may be conical instead of cylindrical.

Filed: 1953-07-10
Abstract: 726,380. Sawing. AETNASTANDARD ENGINEERING CO. July 10, 1953 [Aug. 2, 1952], No. 19222/ 53. Class 145. [Also in Group XXII] Apparatus for severing successive longitudinal sections from continuously moving elongated work T, Fig. 1, such as a pipe, tube or rod, comprises a circular saw 22 mounted on a rotary support 24 for movement in an orbital path, a cam 50 for deflecting the work from its normal path, a shaft 54 to drive the cam at the same rotational speed as but in the opposite direction from the support 24, means driven in synchronism with the latter for periodically moving the shaft 54 towards the work to enable the cam to deflect the work into the path of the tool, and power mechanism acting on the means to augment or reduce movement of the cam shaft. The support 24 is pivotally connected to two counterbalanced cranks 27, 28 driven through toothed gearing 35, 36, 37, shafts 38, 39, 43, Fig. 2 (not shown), a positive infinitely variable drive 15 and reduction gearing 14 from a mill motor 12 which also drives, through bevel gears 60, 61, universal couplings 55, 56 and an extensible shaft 57, the shaft 54. The means for periodically moving the latter towards the work consists of an eccentric support (not shown) which is rotated in a housing 63, Fig. 5, by toothed gearing from the shaft 54. The eccentric support normally displaces the cam 50 by a sufficient amount on each revolution to deflect the work into the path of the saw, but when longer cut lengths are required it is rendered inoperative by a hydraulic cylinder 83 which pivots the housing to a lower position about the pivot 64 so that the work is not defected sufficiently by the cam 50 for it to be engaged by the saw. The hydraulic cylinder is automatically controlled in timed relation with the rest of the apparatus by a valve 87, Fig. 7, operated by a cam 95 which is driven through bevel gears 101, 102 and a gear box, the latter being adjusted together with the drive 35 to cause the work to be cut into pieces of the required length. The cam 50 is notched at 52 to provide a clearance for the saw and is initially adjusted about the pivot 64 in accordance with the diameter of the work by a linkage 107, 109 supporting the cylinder 83 and connected to hand-operated screw adjustment 111. Specification 671,534 is referred to.
