Patent DE-3838557-A1 (DE)
Title: A photoelectric component, essentially consisting of a doped or undoped multicomponent semiconductor which has a gradient of at least one component or at least one dopant
Inventor: SCHMITT HEINZ DR
IPC: H01L31/09
Filed: 1988-11-14
Abstract: The invention proposes, as the simplest corresponding component, a thin film applied to a substrate, e.g. made of glass. In this context, the thin layer may consist, e.g., of doped gallium arsenide. Let two electrodes be applied to the gallium arsenide layer at a spacing of, e.g., 1 cm, and let the gallium arsenide layer, in the zone between the electrodes, have a pronounced stoichiometric gradient, i.e. a change in the ratio of Ga to As. Under illumination it is now possible to measure at the electrodes a voltage of a clear few volts. One of the fabrication methods proposed for the thin gallium arsenide film is cathode sputtering (cathodic sputtering). <IMAGE>
Patent DE-3839918-A1 (DE)
Inventor: OSTERMEIER HEINRICH DIPL ING
IPC: A01D34/73
Filed: 1988-11-26
Abstract: The invention relates to a cutter bar 4 for a lawn mower. The cutter bar 4 has two arms 6, 6A, on the front edges 8 of which cutting edges 9 are provided. Starting from the cutting edges 9 there are, adjoining a flat region, wings 7 which are bent upwards. Arranged centrally is a location hole 19, which lies in the centre of an S- shaped reinforcing bead 14. Provided between the front edge 8 and the cutting edge 9 and the rear edge 18 of the wing 7 is a ridge 12 which runs in a curve shape in the plan view of the upper side 11 of the cutter bar and rises from the surface 11. The ridge 12 starts from an end 13 near to the cutting edge 9 and the axis of rotation X-X and becomes increasingly distant from the cutting edge 9 as the radial distance R from the axis of rotation X-X increases and preferably ends at the rear edge 18 of the wing (7). Improved mowing performance in the case of wet grass and a higher degree of filling of a connected collecting device is thereby obtained. <IMAGE>
Patent DE-3842527-A1 (DE)
Inventor: KUEHL HELMUT DR
IPC: B01D53/86
Filed: 1988-12-17
Abstract: The invention concerns a process for the production of a catalyst for the removal of oxides of nitrogen from exhaust gases by the addition of ammonia. The catalyst, which consists of a carbon-containing material, is treated with bromine or chlorine, or a bromine- or chlorine-containing compound, which is in the gas phase. The treatment can take place in two stages at (adsorption) temperatures of about 100 DEG C to 150 DEG C and (desorption) temperatures of about 200 DEG C to 500 DEG C, preferably using an inert gas which is cycled through the carbon-containing material and with which the gaseous bromine or chlorine or the gaseous bromine- or chlorine-containing compound is mixed.

Abstract: The format of matter printed on a document is automatically selected in response to detection of the identity of the document. As described the document can be identified by e.g. the feedpath used to convey it to the print station, or the identity of a feeder from which it is dispensed to the printer. The invention has particular application to printers which print on either sheets which require a 'portrait' format or envelopes which require a 'landscape' format, and obviates the need for manually selecting the format when changing from one to the other.

Title: Long life homogeneous tyre carcass - has inner layer of porous e.g. butyl rubber made by extrusion so that it has no spliced joints to form stress concns.
Inventor: NAGUMO NOBORU
IPC: B29D30/52
Filed: 1990-09-26
Abstract: A tyre carcass is coated on the inner side and its outer side is coated on the centre section and has tread and side faces. The inner side coating is cylindrical rubber tube which is free from any joints circumferentially. Pref. a tubing of butyl rubber G is extruded and is cut off into a length so as to form a cylinders for use as the inner layer concerned. This is then coated on the inner side with a release agent and fitted on to a drum, making an unjointed layer (16a). A sheet (17) of the carcass is next wrapped round it and jointed along its overlapping edges to form a cylinder (18). Its ends are pressed inwards to make necks (19) and bead-like rings are fitted on. The edges are folded over the raw tyre is formed. The rubber used for this cylinder is preferably highly porous to air-hence butyl rubber. A further advantage of the absence of overlapping spliced joints in the inner layer (16a) is that the carcass filaments are not displaced when the raw tyre is taken to the mould by moulding bags. ADVANTAGE - The construction is uniform as it is free from joints on the inside. It has a good service life as it is free from risk of peeling off and/or breaking caused by joints on the inner layer.
