Title: Manufacture of urethane foam sheets
IPC: B29C44/60
Filed: 1971-08-24
Abstract: 1358932 Laminates; foamed polyurethane sheets SPECIALTY CONVERTERS Inc 24 Aug 1971 [1 Oct 1970] 39569/71 Headings B5A and B5N [Also in Division C3] Integral gas-permeable foamed polyurethane sheets the density of which adjacent at least one side thereof is substantially greater than the density of the body of the sheet are prepared by casting a foamable liquid urethane resin mixture into the form of a thin sheet, one or both sides of the cast sheet being heated while maintaining the body of the sheet at a relatively cool temperature until the sheet has foamed substantially and has become partially cured, the par-  tially cured foamed sheet being compressed while it is in the differentially heated state to collapse the foam on the heated side thereof, the sheet then being released from compression and completely cured. Preferably the sheet has an integral skin layer on one or both sides thereof, the skin layer having cells flattened along their axes normal to the plane of the sheet; the body of the sheet having relatively large isometric cells. Alternatively the sheet may show a density gradient across its thickness without distinct skins being formed. Dense skin layers are suitably formed by maintaining a temperature differential of at least 75 F. between the heated and non-heated sides of the sheet. At a differential less than 75 F. a sheet showing a density gradient will be obtained. Fig. 1 illustrates a method of forming the sheet. A foamable composition 10 is dispensed on to a carrier web 11 and passes between metering rolls 12 to spread it into a uniform layer. The composition on the web is covered with a top sheet 13 and conveyed to area A where the upper surface is heated by means of infra-red lamps 14. The bottom surface of the composition is cooled by blower 15. After the foaming reaction is substantially complete the partially polymerized and differentially heated composition is compressed between rolls 16, the polymerization is completed and the carrier belt and top sheet 13 are stripped from the foamed sheet. In the method described above one or both of the carrier and cover sheets may be laminated to the surfaces of the foam sheet by the adhesive  character of the polyurethane. Alternatively the foam sheet may be post laminated to the substrate which is suitably a felt or fabric.

Title: Steering and ignition lock for motor vehicles
IPC: B60R25/021
Filed: 1971-09-02
Abstract: 1322631 Anti-theft devices YMOS-METALLWERKE WOLF & BECKER GmbH & CO 2 Sept 1971 [9 Nov 1970 6 May 1971] 40919/71 Heading B7J [Also in Division E2] In a steering and ignition lock, the steering- column blocking bolt 13 is actuated from the lock barrel 2 through an axially-moving shifting gate 4 moved by a shifting pin 3 projecting from the lock barrel and engaging a cam surface 30 on the gate to lift it against spring 6. The lower end of the gate has a pocket formation 15 which entrains a hook 14 projecting from the top end of the bolt, with lost-motion, taken up when column-blocking occurs, by a spring 16. Near its upper end, the shifting gate has a circumferential groove 9 and an axial recess 31 receiving a shifting slide 5 which has a congruent groove, these grooves being engageable by a spring- loaded slide-latch 7 projecting from the top end of the barrel, ramp surfaces 8, 56 driving this slide-latch in towards the barrel on axial movement of the slide, except when a key in passage 34 blocks this movement. This prevents the bolt being shot when the key is in the lock and in the 'OFF' position St, but when the key is withdrawn, spring 6 forcing the gate downwardly, also forces the slide-latch inwardly against spring 38 which then causes it to snap out over the upper surface of the gate and of the shifting slide 5 which is prevented from projecting above the gate by a projection 53 working in a pocket 49 in the gate. When the key is inserted at position St and turned towards the starting position, the raising of the gate through cam surface 30 causes the slide latch to hold the shifting slide down until it rotates into the now raised groove 9. The lock may be rotated to its extreme position D for starting and when released, returns to M, the running position, due to the steepness of the last part of the cam surface between these two positions and the pressure of spring 6 and also of spring 32 under the slide 5 because at its extreme upward position it is depressed by a stationary pin (58). A latchng interlock 26 (see also Figs. 11-13, not shown) prevents the lock being returned to the starting position D unless it has first been rotated right back to a position at which the ignition is switched off. There is a "Garage" position G, and a detented position A at which certain accessories may be energised. A notch 57 in the slide 5 indicates this position when turning back. When the lock is turned right back to St, the slide-latch engages in slot 9 in the slide 5 to hold the gate up until the key is withdrawn, as described above. The whole locking assembly is secured in its housing (not shown) on the steering column, by a spring loaded radial pin (19).

Abstract: 1,063,768. Circumferential-flow pumps. SIEMEN & HINSCH m.b.H. Oct. 1, 1965 [Oct. 7, 1964], No.41715/65. Heading F1C. In a self-priming circumferential-flow pump of side-channel type having at least two stages, at least one stage is designed for a delivery and rotational direction which is opposite to the normal delivery and rotational direction of the other stage or stages. Hence, when the pump is driven in the reverse direction so that the suction connection becomes a delivery connection and the delivery connection becomes a suction connection, at least one stage operates in the direction for which it was designed. This ensures that the pump has sufficient gas delivery capacity in both directions of operation to enable it to be self-priming. Where there is an even number of stages, half the stages can be designed for one direction of operation and the other half for the other direction, so that the pump has the same liquid pumping capacity in both directions.
