Abstract: 361,066. Starting oil engines ; pumps. LANZ AKT.-GES., H., 53, Lindenhofstrasse, Mannheim, Germany. Oct. 15, 1930, No. 30916. Convention date, Nov. 22, 1929. [Class_7 (iii).] A pump which delivers heavy oil or a liquid of low viscosity, such as a light oil, has a column of heavy oil always interposed between the low viscosity liquid and the pump plunger. Fuel is supplied to a nozzle f by pipes g, g<1> between which is a casing i containing an outlet valve l, and an inlet valve k for light fuel which is supplied through a pipe m past a cock n. An inlet valve h for heavy fuel is located at the end of the pump barrel a. When the engine stops, the pipes g, g<1> and the casing i contain heavy oil. To start the engine, the cock n is opened and the pump plunger b is operated by a hand-lever d to induce light fuel past the valve k, which opens more easily than the valve h. During the forcing stroke of the pump heavy oil remains interposed between the pump plunger and the light oil in the casing. When the cock n is closed, the engine works on heavy oil. The heavy oil supply pipe to the pump may be provided with a stop valve. The casing i may be formed integral with the nozzle body or with the body of the pump.

Abstract: 1386434 Vibration impacting JOHNSMANVILLE CORP 4 July 1972 [8 July 1971] 31207/72 Heading B5A [Also in Divisions B6 and C3] The surface of deformable material 18 (Fig. 1) is textured by vibration impacting in or on a mould 10 defining a pattern, the recesses of which are, at least partially, filled with a liquid absorbable by the material 18 and serving to reduce the formation of air pockets. As described for forming asbestos-cement wall or spandrel panels, a sheet is produced from asbestos-cement scraps, cement, water, silica, pigments and accelerators by (a) forming a slurry, depositing the solids on a conveyer belt or felt, passing through a vacuum box and rolling, or (b) applying the dry ingredients to a conveyer belt or felt, wetting and rolling, or (c) casting the material, or (d) using a board- or vacuum-forming machine, or an hydraulic press. A green sheet 18 of rolled laminations is then formed. An epoxy resin, asbestos-cement, gypsum or wax mould 10 on a conveyer belt (or the green sheet 18) is sprayed at 14 with a release agent comprising raw linseed oil and kerosene. The mould recesses are sprayed and two-thirds filled at 16 with water and a wetting agent, and receive the green sheet 18 and a covering sheet 20 of wet burlap. After preheating by infra-red lamps 24 or hot air ovens, the mould is moved beneath reciprocating mail boxes 26 that impact vibrate the green sheet 18 into the mould pattern. The burlap 20 is removed, and postheating, at (120-140) F. accomplished by infra-red lamps 44, 48 or hot air ovens. The sheet 18 is removed from the mould 10 by a vacuum head 50, stacked with interspaced sheets of plastics foam and/or asbestos-cement, air cured, and autoclaved, 52, for 20 hours at 100 p.s.i. After trimming to size, dust is removed by abrasive bristles, and acrylic paint sprayed, or pigmented veneers attached. The mould 10 is cleaned by brush and high water pressure.  Nail box.-The nail box 26 (Fig. 3) comprises metal, plastics or rubber nails 32, 34 non- rigidly supported by an apertured plate 30. A rubber mat 38 deadens sound.
