Title: Process and apparatus for compacting web materials
IPC: B31F1/12
Filed: 1962-08-25
Abstract: 1,017,833. Fine crÛping of paper and like web material. BIRD MACHINE CO. & R. R. WALTON. Aug. 21,1962 [Aug. 25,1961], No. 32116/62. Headings D1S and D2B. [Also in Division B6] A very fine crepe effect is imparted to a travelling web of material such as paper, textile fabric, plastic film, woven metal or metal foil by a process in which the material is first corrugated and the corrugations subsequently crushed, the corrugations being supported sufficiently during the crushing stage to avoid creasing or pleating of the material. The supporting of the corrugations may be achieved either by limiting their dimensions so that they are self-supporting or by using a crushing nip having a corrugated form of slightly less height than that of the corrugated web of material so that the corrugations are supported during crushing. In the latter version of the process a series of pairs of crushing rolls of successively reduced corrugation height may be used (Figs. 10-17 not shown). When the support is derived from the web itself, the web 20 of paper or other material is unwound from a roll 16 and passes from the convex to the concave side of a curved axis roll 24 composed of discs 26 which serves to gather the material into corrugations before it passes between two pairs 34, 36 and 35, 37 of intermeshing helically grooved rolls which shape the longitudinal corrugations in the web. The latter are crushed in passing through the nip of a smooth roll 236 and a resilient roll 234 to form the desired fine crepe effect. The material may be subsequently creped in the other direction by passage between intermeshing pinion-type rolls 238, 239 which form transverse corrugations in the web which are then crushed by the two pairs 240, 241 and 242, 243, of smooth rolls.

Abstract: 471,103. Cathode-ray tubes. MANIFOLD, M. BOWMAN-. Nov. 27, 1935, No. 32945. [Class 39 (i)] Electromagnetic deflecting coils for a cathode-ray tube are arranged to prevent " pin-cushion " distortion when the radius of curvature of the screen is less than the distance from the screen to the centre of the deflection region ; for this purpose the coils are so arranged that lines of force due to those producing deflection in one direction, are curved towards the centre of the region. Fig. 2 shows an arrangement of coils A, A<1>, B, B<1> for producing deflection in one direction, and coils C, C<1>, D, D<1> for producing deflection at right-angles to the first, arranged with a magnetic yoke Y having projecting poles 1, 2, 3, 4 the lines joining opposite poles being at 45 to the direction of deflection. The yoke and poles may be omitted, but the coils should still be arranged so that those producing deflection in one direction should be nearer to each other than to those producing deflection in the direction at right-angles thereto. As the deflection increases more rapidly the greater it is, the currents should increase more slowly as they become greater.

Title: Improvements in internal-combustion-operated free-piston engines
IPC: F02B71/00
Filed: 1945-12-06
Abstract: 601,367. Cooling pistons. PESCARA, R. P. Dec. 6, 1945, No. 33071. Convention date, Nov. 18, 1944. [Class 122 (i)] [Also in Group XXVII] The interior of a pneumatic energy accumulator of a free-piston engine or gas generator, sealed at least during normal operation under steady running conditions, is divided into two spaces which communicate with one another through a restricted passage, the arrangement being such that the ratio of the volumes of the spaces varies as a consequence of the movement of the associated free-piston and accordingly creates an alternating current of air between the spaces and the passage is formed in the free-piston and opens close to the piston crown. As shown (Fig. 1), a free-piston gas generator has pneumatic energy accumulators formed between a cover 12 of a cylinder 9 and the interior of a stepped free-piston 5, 8. The accumulator is divided into two spaces by a partition 15 inside the piston having restricted orifices 16 through which the spaces communicate with one another. The smaller space Ca between the piston crown 5a and the partition is fixed in volume while the volume of the larger space a, b, c varies as the free piston operates. The movement of the piston thus sets up an alternating current of air between the two spaces and helps to cool the crown 5a of the piston. A space between the piston 8 and a partition 11 forms a compressor supplying compressed air to a scavenging space 2. The exhaust products are delivered through ports 4. The crown 5a of the piston is removable and is held in position by a split sleeve 17. In a modification, Fig. 3, a cushion space a, b, Ci, Cb of a gas generator is divided into two parts by a restricted passage between the end of a tube 23 within the power piston 5 and cooling ribs 24 on the interior surface of the piston. A modification of this arrangement is described in which an annular partition between the tube and the interior of the piston divides the space within the piston into two parts, the portion nearer the compressor cylinder being connected to the space outside the power piston by holes in the tube. In a second modification of this arrangement, the outer end of the compressor piston 8 is closed and the space within this piston is connected tor the space within the power piston. In each of these arrangements a cooling coil 38 supplied with cooling water is located within the tube 23. In a further modification comprising a two-stage opposed free-piston compressor, one end of which is shown in Fig. 5, a cushion space d, e at each end is divided into two parts by a restricted orifice 37, the space d being of fixed volume. The power pistons 32 are each connected to compressor pistons 33, 34 which compress air on the outward stroke. The piston 33 works in a cylinder 30 forming a lowpressure compressor and the piston 34 forms with a cylinder 31 a high-pressure compressor. A cooling coil is located in the space e.
