Title: Method and device for casting foam plastics
IPC: B29C33/20
Filed: 1964-10-22
Abstract: 1,083,254. Moulding foamed synthetic resins. BOFORS-TIDAHOLMSVERKEN A.B. Oct. 22, 1964 [Oct. 23, 1963], No. 43175/64. Heading B5A. Foamed synthetic resin articles, in particular sheets of foamed polyurethane, are cast in a mould which comprises a base-plate 1, e.g. of laminated wood, and a vertically displaceable cover 3, e.g. of aluminium, the cover 3 being initially positioned to give a predetermined moulding volume equal to the volume of the starting materials to be introduced through a port 4, and being displaceable while remaining substantially parallel to base-plate 1 until the materials have expanded to a predetermined volume. The cover 3 is maintained parallel by spring-tensioned guides 8 fixed to beams 6a, the latter acting as stops for the cover. Brackets 5, having set-screws 5a, allow the initial position of cover 3 to be determined and the vertical displacement of the cover may be varied by attaching spacers to beams 6a. In an example, a polyol-isocyanate reaction mixture was formed by two jets directed towards one another, emission taking place under a pressure of 100 kg./cm.<SP>3</SP> from the nozzle of a mixing head placed in port 4. The moulding space was filled in about 6 seconds, the enclosed air being driven out between cover 3 and frame 2. After filling, port 4 was closed, 4-5 seconds later cover 3 began to rise, the cover being stopped by beams 6a after a further 8-10 seconds. To produce a lined product a sheet of wood fibre, plywood, steel, aluminium, glass fibre reinforced resin or tar paper may be placed on base-plate 1 prior to casting. An example of a profiled product is given where strips of foamed resin and wood are placed lengthwise and alternately against frame 2 between base 1 and cover 3, the wood strips being removed after casting to produce a comblike profile.

Abstract: 1,049,729. Internal shoe drum brakes. H. TEVES, E. A. TEVES and M. TAUSEND, [trading as ALFRED TEVES MASCHINENUND ARMATURENFABRIK K.G.]. Oct. 23, 1964 [Nov. 23, 1963], No. 43314/64. Heading F2E. In a duo-servo type internal shoe drum brake, the braking force from the primary shoe to the secondary shoe is transmitted through a pair of elements 5, 5a, which form slack adjuster nut components of threaded pins 4, by a one-armed lever 10 pivoted between said elements and provided with pairs of beads 17, 17a and 19 and 19a. On expansion of the shoes by a double acting brake cylinder (not shown) disposed between the opposite ends of the shoes, the lead shoe, for instance shoe 2, advances the element 5 and pivots the lever anti-clockwise thereby causing the beads 17a and 19 to disengage and the beads 17 and 19a to transmit the braking force from shoe 2 to shoe 3 in proportion to the respective distances of beads 17 and 19a from the lever pivot. The lever may be fixedly pivoted in a casing 1 or in yoke secured in the casing, Fig. 1 (not shown) Alternatively, as shown, the lever is pivoted in a transverse sliding block 11, the block being raised by rollers 13 on movement to the left of the linkage 15 when the hand-brake is operated to disengage the beads 17 and 17a. The braking force is then transmitted directly from shoe 2 to shoe 3 by beads 19 and 19a without any force reduction.

Abstract: 1441510 Superconductive devices INTERNATIONAL BUSINESS MACHINES CORP 17 Oct 1974 [30 Oct 1973] 44971/74 Heading H1K In a Josephson tunnelling junction having a plurality of control conductors and functioning as a logic gate, the junction electrodes are so constructed as to overcome the normal non- linear distribution of tunnelling current, this effect arising from the screening circulating current through the junction and its electrodes produced as an outcome of control conductor energization. With such a linear tunnelling current distribution each control conductor then produces the same effect on the logic gate for given operating conditions. In each of the arrangements described a superconducting ground plane is used although not illustrated. In a basic arrangement, Figs. 8 and 9, a tunnelling barrier 36 is provided between two rectangular superconducting electrodes 28, 30, each electrode being integral with a superconducting extension of lesser width. To provide the required linearity of junction current distribution, each rectangular electrode M2, M3 has a length l 1 , l 2  to the junction at least equal to the distance W1, W2 or W3, W4 at the root of the respective extension. In a modification a side entry extension is provided, Fig. 10, the conditions in this case being that l 1  is at least equal to W5. In an alternative arrangement, Fig. 12, electrode M3 is extended from the junction over the electrode M2 with an intermediate insulating layer I2, the extension length l e  being at least equal to the junction width. A modification, Fig. 13, which uses two control electrodes 114, 116 has the extension provided in the form of a separate superconducting layer 118. Three control electrodes M4 are provided in Fig. 14 in which an extension superconducting layer is provided by overlap of M2 and M3. The Specification describes the effect of the circulating screening current and how this is overcome in detail, Figs. 1 to 7 (not shown), this current under normal conditions being concentrated along a restricted path on a superconductive surface below an energized control conductor but being distributed uniformly on the opposite surface.
