Patent DE-2426053-A1 (DE)
Title: Travelling field support and drive for tracked vehicle - with low friction wheels giving positive guidance but small support
Inventor: HEIDELBERG GOETZ DIPL PHYS
IPC: B61B13/08
Filed: 1974-05-30
Abstract: A drive and guide system for track-guided vehicles comprises permanent magnets mounted in the vehicle beneath iron components or stators, so that these magnets are attracted upwards towards the stators and support the weight of the vehicle. Pref, the stators comprise conductors which also cooperate with the permanent magnets to provide the forward drive for the vehicle. The clearance between the stators and permanent magnets is pref. determined by mechanical, hydraulic, electrical, or magnetic means, esp. by wheels running along the underside of the stator, esp. on fibre-reinforced plastics strips, or along the upper side of a guide rail. The tread surface of each wheel pref. has a very low coefficient of friction, obtained esp. by the addition of "TEFLON" (RTM) or molybdenum disulphide. Pref. the tracks or stators are 12-32 cm wide, the air gap is 5-25 cm, the proportions being such that 80-120% of the wt. of the vehicle is supported by magnetic attraction.

Title: Moulded panels with visible, exposed aggregate - where aggregate is pressed into layer of soft mortar on concrete core
Inventor: WAGNER KARL-EUGEN
IPC: B28B19/00
Filed: 1975-03-21
Abstract: Process for mfg. concrete mouldings, esp. panels for facings, i.e. exposed aggregate, with a surface layer of gravel or chips only bonded on its underside. The novely is that before the compacted concrete core has set, it is covered with a layer of fine-grained, adhesive mortar which is softer than the core, followed by the top layer of loose gravel or chips which is pressed into the adhesive mortar; and that the thickness of the layer of the adhesive mortar; prior to pressing in the top layer, does not exceed half of the average dia. of the gravel or chips in the top layer. The adhesive mortar is pref. compacted on the concrete core prior to applying the top layer, and the mortar is pref. cement to which plastic emulsions are added to improve adhesion. Used for mfr. of moulded panels where an aggregate with a uniform grain size is visible on the surface. The conventional operation of washing the mortar away from the visible surface, e.g. with a high-pressure water spray, is eliminated.

Title: Axial antifriction bearing fastening - uses circular spring ring in square groove tensioned inwards
Inventor: OHM WERNER DIPL ING DR
IPC: H02K5/173
Filed: 1975-04-29
Abstract: The axial bearing fastening is for the external ring of an anti-friction bearing, inserted into a bore. The external ring supports itself in an axial direction against a cover, cast-in one side; and in the opposite direction against a ring, positioned in a concentric groove in the bore. The ring consists of a circular spring ring (10). When built-in, under its own spring tension, the ring has an internal diameter corresponding to that of the bore. After assembly of the bearing, the ring is radially tensioned inwards by screws (14, 15) which are positioned in the bearing housing at a small distance with their axes parallel to the bearing bore. The groove accommodating the ring has a square cross-section.

Title: Thermal cross flow processing oven for solid fuel - has vertical grate with deeper centres for uniform fuel flow rate
Inventor: NASININ NIKOLAJ ANDREJEWITSCH
IPC: C10J3/24
Filed: 1975-05-07
Abstract: An oven for the thermal processing of solid fuel by the cross flow of a heat transport gas has two vertical grates which divide it into three spaces for gas distribution, low-temperature carbonisation and for the steam/gas mixture. The grates end at the bottom with a projecting part in the middle and higher parts on both sides towards the walls. This equalizes the flow rate of the solid fuel over the cross-section of the low-temperature carbonization space. The better heat and mass exchange conditions result in a higher oven throughput, better fuel processing and an increased thermal efficiency of the process.

Title: Foundry charging crane gantry - has main crab of U-section with bogie rails clearing gases during charging
Inventor: RICHTER DIETER
IPC: B66C17/08
Filed: 1975-06-20
Abstract: The foundry charging crane has pairs of gantry beams joined together by end beams joined together by end beams and equipped with rails for two bogies, coupled together so as to form a main crab. The gap between the pairs of gantry beams is bridged by an auxiliary crab travelling below. In plane view, the main crab (9, 10, 19) is of U-section, so that when the crab is in the charging position, the component (19) joining the bogies (9, 10) is largely clear of the hot gases rising from the cupola and furnace mouth. It can be so arranged that during the charging operation it is above the gantry end beam.
