Title: Data card and associated read system - has closed and open loop code storing elements sandwiched between nonmagnetic cards
Inventor: YAMADA SIYOUHACHI
IPC: G06K7/08
Filed: 1975-09-06
Abstract: The card for the storage of coded information is characterised by an opaque non-magnetic plate (10) of pre-determined form and a number of code storage elements (30) of electrically conducting material. These are typically of flat hollow square profile with small cut-out depressions (32) along one edge. A second non-magnetic plate (20), similar to the first, is fixed by adhesive so as to form a sandwich construction. The card is fed through the gap in an induction magnetic and this produces a current around each storage element and produces a "hot-spot" in the neck section caused by Joule effect heating. An electronic circuit may be used for pick-up signals which are different for a neck section or a complete gap.

Title: Microscopic measurement of paint coating thickness - using brittle notched sample to render coating visible
Inventor: OTTO JUERGEN DIPL ING
IPC: G01B9/04
Filed: 1975-11-20
Abstract: The method with precise measurement of even very thin coatings, is carried out by using a brittle, mainly notched sample member to render the coating visible. The sample member is pref. attached to or placed on the workpiece prior to coating, then coated together with the workpiece, after which it is removed and fractured. One half of the sample member is placed under a microscope with out further treatment. As the edges of the sample member are often rounded, distorted, etc., the sample member has to be broken to obtain the true coating thickness, while avoiding plastic deformation of the coating during fracture. Also, the fracture must provide a smooth surface perpendicular to the upper surface of the sample member, for which purpose e.g. glass or porcelain is suitable.

Title: Hydrogen sulphide removal from feed gas - by contacting the gas with a catalyst to convert hydrogen sulphide to sulphur
Inventor: HANSFORD ROWLAND C
IPC: B01D53/52
Filed: 1976-04-02
Abstract: The treatment of feed gas and extn. of elemental S, which contains also small amts. of a gaseous oxidising agent such as O2 and/or SO2, comprises contacting the gas at 121-232 degrees C with a catalyst. The catalyst is a reduced oxide and/or sulphide of a metal of gp. IVA and/or VIA on a non-alkaline, porous refractory oxide carrier. The process is carried out at such a rate that >=80% of H2S is oxidised to elemental S. Free S is sepd. from the waste gas. Desulphurisation of a feed gas which contains S in the form of SO2, COS, CS2, CH3SH, SO3 and S vapour is effected by hydrating the gas at 149-427 degrees C by contacting with a catalyst composed of an oxide and/or sulphide of a metal of group VIA and an oxide and/or sulphide of a metal of the Fe gp. at a rate to reduce >=80% of S constituents to H2S. The gas is dehydrated to 15 vol.% water vapour and a mixt. of the gas and a gaseous oxidising agent contg. O2 and/or SO2 is treated in order to extract elemental S. Method does not require the costly multi-stage absorption-oxidation procedure of the Claus method and is used for the treatment of acid natural gas and tail gases of the Claus process.
