Abstract: 917,123. Maps &c. GOODSON, A. E. Sept. 1, 1960 [Sept. 10, 1959], No. 30944/59. Drawings to Specification. Class 146 (2). A process for making relief maps consists in the steps of drawing or printing a map on a sheet of transparent or translucent ductile material, placing the sheet on a resilient surface, such as tightly compressed felt fibres, outlining by indenting parts of said map, reversing the sheet on the surface and depressing other parts of the map and then photographing the modelled sheet with oblique lighting. The modelled sheet may be stuck by its marginal areas and other underformed parts to a base-board in a position corresponding to major features of the map marked thereon and air thus imprisoned may, by manipulation, be caused to increase the relief. If desired, a modelling substance can be placed on the board so that it can be marked to adapt itself to the modelled sheet. The sheet may be treated prior to photography by the addition of various materials, such as sand to represent bouldered areas, and may then be coated white.

Filed: 1963-08-09
Abstract: Germanium is deposited epitaxially from a gas on to a heated monocrystalline Ge core which has its longitudinal axis parallel to the [111] or [100] crystal axis and has been treated by removal of material from its surface so that it has a uniform cross-section and is free from surface crystal dislocations.  With a [111] axis, the core may be treated to give a hexagonal prism, 3 of whose edges coincide with the "growth seams" visible on a core obtained by zone melting or crystal pulling; the grown rod is then symetrically staggered with respect to the core.  With a [100] axis, the core may be treated to give an octagonal prism. Alternatively, the core may remain cylindrical, the treatment merely removing dislocated regions. The treatment may be mechanical (e.g. grinding, electron and/or ion bombardment, sand blasting with quartz sand, or polishing) followed by chemical etching (e.g. with an etchant produced by shifting the equilibrium of the reactant gases, or with a mixture of 65% HNO3 and 38-40% HF) which is continued until bubble formation subsides, or may be stopped, e.g. with HNO3.ALSO:Silicon is deposited epitaxially from a gas on to a heated monocrystalline Si core which has its longitudinal axis parallel to the [111] or [100] crystal axis and has been treated by removal of material from its surface so that it has a uniform cross-section and is free from surface crystal dislocations.
