Title: Improvements in or relating to stencilling processes
IPC: B05D1/32
Filed: 1929-03-13
Abstract: 330,608. Field, H. S., (Atrax Ges.). March 13,1929. Stencils and stencilling. - In a process for stencilling on flat or curved surfaces, a sheet of metal foil, for example tinfoil, is fixed by an adhesive, such as a mixture of gelatine and glycerine, to a sheet of glass or other hard support, a design is outlined in the foil by scoring, the foil is then removed and secured bv an adhesive to the surface to be treated, parts of the foil are removed, and colour or the like is applied by painting, spraying, or powdering. To facilitate removal of the foil from the support, a gummed backing-sheet of paper, linen, or other fabric may be applied thereto after scoring. The. adhesive between the foil and the glass is softened by heat, the foil and backing-sheet being fixed to the surface to be. treated by an adhesive comprising honey, or dextrine mixed with glycerine, whereupon the adhesive between the foil and the backing is softened by wetting and the backing is removed. The parts of the foil left on the surface are finally removed, e.g. by suction. To enable the backing-sheet to be pressed easily and uniformly on to the foil, the latter may be treated with a liquid such as glycerine, milk, or diluted honey. Before applying the colour, the exposed parts of the surface to be treated and the contour edges also may be treated with a hardening-agent such as formaldehyde or alum. Multicolour stencilling may be effected by removing parts of the foil, applying colour, removing other parts, and so on.

Title: A method of manufacturing a heat exchanger unit
Inventor: FELTON FREDERICK DUDLEY
IPC: B21D53/08
Filed: 1956-03-19
Abstract: 814,539. Making heat exchangers: brazing. REVO ELECTRIC CO. Ltd. March 11, 1957 [March 19, 1956], No. 8453/56. Classes 83 (2) and 83 (4). [Also in Group XIII] A method of making a heat exchange unit comprises forming a body from a plurality of sheet metal pressings 7, Fig. 1, e.g. of copper assembled in contact, introducing into a longitudinal hole or holes in the body a tube or tubes 8, e.g. of stainless steel, each tube having its periphery covered with fusible foil, subjecting the body to longitudinal compression, either expanding the tube or tubes or compressing the body to clamp the foil prior to heating to fuse the foil and bond the tube or tubes to the body. The metal pressings 7 may be flat and fit in close facial contact or alternatively each may have an integral cylindrical flange 7a around each hole, Fig. 5, which abuts the adjacent pressing. The brazing foil, e.g. 65 per cent copper, 30 per cent manganese and 5 per cent nickel, may be helically wound on to the tube or tubes, after cleaning the latter by abrasion, so that the edges are in contact but do not overlap. An adhesive and encircling clips may be used to temporarily locate the foil, the intermediate clips being removed as the tube or tubes are introduced into the body. The longitudinal compression is applied to the body by rods 10 passing through it and end plates 9. After the tube or tubes 8 have been expanded tightly against the body or the body has been compressed on to the tube or tubes, the rods 10 and end plates 9 are removed and retaining washers 12, e.g. of stainless steel, are forced on to the tube ends to bear tightly against the ends of the body. The assembled unit is then heated in a furnace in a neutral gas at 940‹ C. for 40 minutesto fuse the foil and to relieve the stresses in the tube or tubes or in the body.

Title: Improvements in fuel-injection internal-combustion engines
IPC: F02B3/06
Filed: 1951-04-12
Abstract: 721,593. Direct injection engines. MOTORUNION, NARODNI PODNIK, and BOTTGER, J. April 12, 1951 [April 12, 1950], No. 8533/51. Class 7 (3). A fuel-injection engine comprises an elipsoidic or bulb-shaped combustion chamber which is arranged in the piston crown and is in communication with the cylinder through a restricted substantially circular transfer opening and a fuel nozzle arranged within the cylinder head which is eccentrically disposed with respect to the main axis of the cylinder and discharges a fuel jet through the transfer opening into the combustion chamber and the axis of the restricted transfer opening the main axis of the combustion chamber and the axis of the cylinder lie in a common plane and the ratio between the distances of the points where each of these axes penetrates a plane coinciding with the top wall of the piston in its upper dead centre position from the point where the longitudinal axis of the fuel nozzle penetrates the top of the piston in its upper dead centre position is substantially the same as the ratio respectively between the diameters of the transfer opening the combustion chamber and the cylinder. In a modification the axis of the fuel nozzle lies within a plane which is parallel to and to a certain extent offset in respect of a plane defined by the centre line of the cylinder and the main axis of the combustion chamber and the distances defined above are taken from the perpendicular projection into the lastmentioned plane of the point where the longitudinal axis of the fuel nozzle penetrates the piston in the upper dead centre position. In Fig. 2 the ratio between the distances of the points where the axes of the transfer opening e<SP>1</SP> of the combustion chamber e and of the cylinder e<SP>0</SP> penetrate a plane coinciding with the top wall of the piston in its upper dead centre position with respect to the point where the axis of the fuel nozzle intersects the piston head in its upper dead centre position is substantially the same as the ratio between the diameters of the transfer opening dl of the combustion chamber d and of the cylinder d<SP>0</SP>. In practice the combustion chamber will not be rectangular in section as shown but will have a rounded shape. Fig. 3 shows a particularly advantageous form of combustion chamber. The modification is shown in Fig. 5. In this modification a rotary movement around the combustion chamber may be imparted to the combustion air. The inlet valve is so disposed that a rotary movement is imparted to the air sucked in during the suction stroke and a uni-directional turbulence is obtained' in the combustion chamber during the compression stroke. In another embodiment (not shown) the axis of the fuel nozzle is inclined to the plane defined by the centre line of the cylinder and the main axis of the combustion chamber.
