Filed: 1928-07-31
Abstract: 319,416. Dessau, M. M., and Flores, S. L. July 31, 1928. Flooring and paving tiles or blocks. - Floor covering or similar material is made by uniting a layer of rubber to a backing of sheet cork by vulcanization, without the intermediary of rubber solution. Unvulcanized rubber is spread upon sheet cork, for instance a number of sheets of cork united edge to edge, and vulcanized by being passed between hot rollers, or in a press. The edges of the cork strips are formed with projections and recesses, or dovetails, as shown at A, B, Figs. 2 and 3. The cork sheets may be formed with recesses or perforations in order to assist adherence of the rubber. The cork may have a special surface prepared on it before application of the rubber; for instance the surface may be coated with friction material or with latex. Grooves or recesses may be made in the rubber coating and filled in with differently coloured rubber or other material. The material may be laid on roads, in which case it is made thicker than for other purposes, and the rubber surface provided with intersecting cuts. Figs. 7 and 8 show the material, formed of a thin sheet of cork C, perforated with holes G, and a relatively thick layer of rubber R. The cork backing may also be formed with protuberances J, Fig. 11. The material may be cut into tiles and laid, the joints being filled with rubber. In the case of roads, the material may be laid on a bed of bitumen. The edges of sheets of the material may be serrated or dovetailed so as to interlock when laid. The lower surface of the cork may be formed with grooves or corrugations to afford secure adhesion when the material is laid on a plastic layer such as bitumen. Thermo-plastic or soluble adhesive material may be applied to the under side of the cork for attaching the material to the surface to be covered. Fabric, rubberized fabric or rubber may also be applied to the under side of the cork.

Filed: 1926-09-08
Abstract: 270,941. Pelkman, J. H. N. Sept. 8,1926. Bakers' ovens.-In a bakers' oven in which the heating gases are caused to pass along a sinuous path through damper-controlled passages extending horizontally above, and below, and vertically at the ends of superposed baking-chambers, the horizontal passages are in the form of tubes 13, 14 at the tops of the chambers, and between these tubes are masses 11 of refractory material, iron or concrete, which act as heat accumulators. A network screen 22 formed of bar or strip metal may be interposed between the heating-tubes and the baking-chamber, and by varying the thickness of the metal and the mesh of the network the top heat in the different baking-chambers can be equalized. In the uppermost chamber of the series the screen is preferably omitted. The fireplace 5 is situated beneath the baking-chambers and the lowermost floor 8 is supported on pillars 10 so as to provide a large flue space 19 beneath the floor. Two vertical flues 18 lead from this flue space, and the vertical flues 24 at the opposite end of the oven and the top flues 20, 21 are also in duplicate, so that the heating of the right and left hand sides of the oven chambers can be controlled independently. Dampers 27, 29, 30, 31 can be set to pass the heating-gases through the tubes 13, 14 either in series or in parallel, and the operating- handles for the dampers are preferably brought to the end of the oven where the doors for the baking-chambers are situated. Damper-controlled ventilating-passages 32 lead from the baking- chambers to the chimney flue.

Title: Improvements in or relating to hydraulic controls for brakes
IPC: B60T11/20
Filed: 1949-08-26
Abstract: 678,519. Hydraulic brakes. BOLSEZIAN, G., and STOP SOC. AR.L. Aug. 26, 1949 [Aug. 31, 1948], No. 22298/49. Class 103 (i). A master cylinder that actuates two separate hydraulic brake systems connected at 5 and 6 comprises a main pressure applying piston 2 of known type and also a flouting piston 7 through which passes a hollow spindle 12, one one of which projects into passage 5. As shown in the brakes released condition, fluid may pass from the reservoir 3 past piston 2 by groove 4 and past piston 7 by port 15 in spindle 12, the central space 14 and ports 13. When the piston 2 is moved to the left to apply the brakes, the systems connected to ports 5 and 6 become isolated as soon as the ports 13 pass under the gasket 17; thereafter the piston 7 acts to transfer pressure from the space between the two pistons to that connected to connection 6. If a pipe connected at 5 should fracture, resulting in loss of liquid, the spindle 12 will be forced through piston 7 until spring-lock ring 18 engages groove 19, thus locking the spindle 12 with its ports 15 under gasket 9 so that the two pistons 2 and 7 then act as one. If a pipe connected at 6 should break, the piston 7 is driven along spindle 12 until the spring ring 21 locks it by engagement with groove 22 in a position in which it is held tight against the gasket 17. Two modifications are described.
