Title: Improvements in apparatus and method for depositing sheet material
IPC: B29C48/08
Filed: 1969-02-14
Abstract: 1,267,711. Sheet casting; laminates. INTERNATIONAL PLAYTEX CORP. 14 Feb., 1969, No. 8287/69. Headings B5A and B5N. An apertured elastomeric sheet of, for example, rubber or P.V.C. is formed by casting a latex on to the surface of a rotating internally heated cylinder 14 from a reservoir 121, the forward and rear lowermost edges of which are formed by flexible wiper blades 132 and 140. Located adjacent the forward blade 132 is a pool 150 of liquid coagulant effective to prevent any filming over of the tops of the projections 110 thereby ensuring that through apertures are formed by the projections. Filming may be alternatively prevented by directing radiant heat at the region adjacent blade 132 or by maintaining a suitable gaseous vapour in the same region. As a further alternative a liquid coagulant may be supplied to the surface of the cylinder upstream of the reservoir. Regions of thicker and thinner material may be formed by varying the height of the projections, the material of the thinner regions preferably containing less apertures to preserve uniform stretchability. Instead of casting upon a cylinder a belt may be used (see Fig. 39, not shown). After being stripped from the casting surface the cast sheet may be laminated to covering sheets of, for example, stretch fabric. In the embodiment shown in Fig. 2 the cast sheet is washed by jets 22, 24 and 26, is dried by rolls 25, is passed between adhesive applicators 35-1, 35-2, and is laminated by rolls 36 to stretch fabric layers 31 and 33 fed along pin and tenter frames 31-1 and 33-1. The laminate thus formed is finally passed through blanket belt portion 38, on to conveyer 40 and thence into oven 45.

Abstract: 766,307. Fuel-injection engines. DAIMLERBENZ AKT.-GES. March 22, 1955 [March 22, 1954], No. 8372/55. Class 7 (3). In an-injection engine with a turbulence chamber disposed eccentrically in the piston crown, liquid fuel being injected by an eccentrically disposed and inclined jet nozzle, the side of the chamber which is remote from the cylinder axis extends as an inclined surface upwardly from the bottom of the chamber to the peripheral edge of the piston, a liquid jet being injected in the direction of the air flow over the inclined surface when an eddy motion is created whereby the fuel is distributed as a film or layer over the surface. As shown in Fig. 2 the fuel stream 25 is diffused while the stream 26 is relatively dense. In Fig. 4 the fuel is sprayed in three streams 25a towards the wall 17. In Fig. 5 the wall 17 is slightly concave. The fuel is sprayed in such a way that a part 27a preferably the greater part impinges on the wall 17 directly with the fuel in the liquid state while the remainder 27b is distributed over the air space of the chamber. A simple pin nozzle giving a funnel shaped jet can be used. In Figs. 1 and 2 the chamber 16 can be produced by a milling tool as indicated at 23 and advantageously by pivoting the tool and piston in relation to one another about a point A in the piston crown. The cylinder 10 is one of a series. The inlet and exhaust valves are located in the water cooled cylinder head 12. One of the valves is seen in Fig. 1 and marked 13. The fuel may be supplied fanwise in one or more streams or may be injected in several jets.

Abstract: 806,229. Liquid-blast switches. WESTING- HOUSE ELECTRIC INTERNATIONAL CO. March 18, 1957 [March 27, 1956], No. 8783/57. Class 38 (5). A liquid-blast switch has an arc-extinguishing unit 3 immersed in an arc-extinguishing liquid, a lower closure plate 49 for the unit, an inverted cup-shaped cylinder 46 extending upwardly within the unit from the plate, and a pumping piston 55 operable within the cylinder for assisting in arc extinction. In the arrangement shown, passages 47 and openings 53 are provided in the wall of the cylinder so that the space 50 above the piston is in communication with the outside of the unit and the space 56 below the piston communicates with the interior of the unit. When a conducting cross-bar 7 is lowered, a spring 45 causes a downward movement of a moving contact 43 to separate the contacts 35, 43. As this occurs a spring seat 58 moves down under the bias of springs 59, 60 until it engages the lower end of the piston 55. The piston is then moved down to pump liquid into the interior of the extinguishing unit immediately or when the pressure generated by the arc subsides. When a contact disc 44 carried by the contact rod 43 engages an abutment 64, the opening movement of the contact 43 ceases and a contact 61 on the cross-bar 7 separates from the contact disc 44. Normally-open spring-loaded disc valves 22 permit the circulation of liquid by convection through the unit 6 until the valves 22 are closed by the pressure generated within the unit 6. The fixed contact assembly may comprise a flanged stud 42 and spring-biased contactfingers 35 with arc resisting tips 39a, the fingers being formed by slotting a tubular contact member after an annular arc resisting member has been brazed in position. The arc-extinguishing device 57 may be provided with leafspring valve members (not shown). Specification 768,911 is referred to.
