Patent GB-2032463-A (GB)
Title: Thermal Oxidation of Stainless Steel to Produce Optimum Solar Absorption Characteristics
IPC: C23C8/14
Filed: 1978-08-31
Abstract: Spectrally selective solar surfaces have been produced after heating the austenitic stainless steel AISI 321 to a firing temperature of 843K for a time ranging from 10 to 20 minutes. The optimum values of solar absorptance and near-normal thermal emittance are found to be 0.92+/-0.02 and 0.22+/-0.02 respectively. Severe temperature treatment like quenching in liquid nitrogen at 77K shows no adverse effect upon the quality of coatings produced by thermal treatment. The values of solar absorptance and near-normal thermal emittance remain unchanged after 'quenching' of the heat treated samples. It is believed that suitable thermal treatments given to ferretic steels and other alloys and metals may also result in spectrally selective solar surfaces.

Patent GB-2013992-A (GB)
Title: Electrical contact assembly
IPC: H01R13/64
Filed: 1979-01-22
Abstract: A female contact 40 having at least one contact arm 41 with an outwardly diverging tip end 44 for guiding the tip of a male blade inserted into the contact is housed in a chamber having a contact arm abutment 36 mounted on the chamber sidewall 31 and projecting inwardly into the chamber. The abutment 36 is aligned with the contact arm 41 of the female contact and is spaced outwardly from that arm to set the limit of acceptable outward contact arm deflection. A portion of the contact arm extending rearwardly from the diverging tip end 44 is channelled to allow this end to clear the abutment 36 when the contact is inserted longitudinally into the chamber from the rearward end 38 thereof. The abutment 36 limits outward displacement of the contact arm 41 to prevent the overstressing of the arm by an engaging male blade and may be formed as a unitary part of the pocket sidewall 31. The arrangement permits the use of brass contacts 40. <IMAGE>

Title: Photoengravure Printing Plates
IPC: B41N3/00
Filed: 1979-01-30
Abstract: Patent 563028 benefits halftone obtained by the use of a step in the form of a cross, is conjoined by patent 901,412 inking. Halftone method, simple inked halftones checkboard dots form changed with creation of cruciformed segmented dots and dotcell inking not only from block plate top surface, but intermediate dot depths in alteration of area size to produce plus inking and minus inking effects. Highlight dot pressure restriction gives less inking, gives more inking pressure from other tones to enhance quality contrasts from dot cell inking. This method of printing construction use creates different plate inking pigment liquid application from halftone dot element of changed areas compounded. Photogravure process prints from highlights to shadow tones with ink density applied of graduated thinness. These methods are somewhat adapted for letterpress photo-litho printing adjustment without doctor blade use. High speed running machines do not best feed ink yet to halftone pictures so newsprint quality suffers, should be especially improved from these methods and from rough cheap papers.

Title: Fabrication of a semiconductor device in a simulated epitaxial layer
IPC: H01L21/225
Filed: 1980-04-22
Abstract: A simulated epitaxial layer 18 is formed at the surface of the semiconductor body by implanting impurities, of a conductivity determining type opposite to the conductivity type of the body, into the body to a depth below the surface of the body less than the desired thickness of the simulated epitaxial layer. The body is then heated to a temperature above the diffusion temperature of the implanted impurity. The application of heat is terminated after the implanted impurity has diffused to a distance below the surface of the semiconductor body approximately equal to the desired thickness of the simulated epitaxial layer. Designated areas of the simulated epitaxial layer are doped to alter the conductivity thereof to form source and drain regions 22, 24. An insulating layer 26 is formed on the surface of the semiconductor body above the channel region. Metallized areas 28, 30, 32 are formed over the source and drain regions and the insulating layer, respectively, to act as electrodes.   <IMAGE>
