Patent DE-3933320-A1 (DE)
Inventor: FRIEDEMANN DIETER
IPC: H05K7/14
Filed: 1989-10-06
Abstract: The invention relates to an apparatus for sensing and processing electrical signals, having an apparatus housing 1, which is divided into plug-in chambers 2 and 4 which are open towards the front side, it being possible to arrange a controller plug-in unit 3, containing an electronic controller unit, in one plug-in chamber 2, and a power supplying plug-in unit 5, containing a power supply, in a second plug-in chamber 4. The controller unit and the power supply can be connected by means of leads both to one another and to connecting contacts 31 for external connections. A controller plug-in unit 3, with a second electronic controller unit, identical to the first controller unit, and a power supply plug-in unit 5, with a second power supply that is partially identical to the first power supply, can be arranged in further plug-in chambers 2 and 4 which are open to the front side of the apparatus housing 1, which plug-in units can be connected by means of leads both to one another and to connecting contacts 31 for external connections. The first controller unit can be supplied with power from the first power supply and the second controller unit can be supplied with power from the second power supply. Input signals can be supplied simultaneously, in parallel, from the exterior via the leads to both controller units and can be processed in synchronism by both controller units. Output signals can be generated exclusively from one of the controller units depending on the signal processing and the status of the controller units. <IMAGE>

IPC: E01H5/06
Filed: 1989-12-11
Abstract: A snowplough with a device for travelling over obstacles on the ground has a blade (1) connected to a frame (10) via rigid upper and lower links. The frame (10) is fitted to the front of a vehicle so that it may be raised and lowered.

Title: Drum for dipping into aq. solns. - has sets of polyethylene perforated units welded together to have polygonal end view but fixed to polypropylene end discs e.g. by screws
Inventor: HENIG HANS
IPC: C25D17/20
Filed: 1989-12-16
Abstract: Revolving immersion drum is made of a non-conducting synthetic material and is used to treat powdered materials with aqueous solution either chemically or electolytically. The drum consists basically of two parallel ends and a perforated cylinder fixed between them but having pref. a polygonal end section; the cylinder is actually made up of a number of adjacent lngitudinal rectangular and pref. flat perforated sheets laid together to form the polygonal end view; between them and at the corners of the polygon they have reinforcing rods; at least one of the sheets is a removeable cover. The facing sheets of the drum are joined together into one homogeneous unit by a heated butt-welding process; they are fixed on the end plates by other means than that welding operation by e.g, screws. The drum ends and facing sheets are pref. made of different materials e.g, high hol. wt. polyethylene and polypropylene. ADVANTAGE - The prod. is highly resistant to mechanical or thermal factors in service. Cuts out use of heated butt-welding polyethylene. The prod. saves about half the cost of the welding process and its assembly by e.g, screws saves time and is safe.
Patent DE-3941974-A1 (DE)
Title: Low magnetic efficiency material - used as stators and rotors in current generators
Inventor: LODDER DIRK
IPC: H01F1/14
Filed: 1989-12-15
Abstract: Materials with low magnetic efficiency, when used as the stator and rotor in a generator, allow prodn. of only a relatively low field strength at the same high magnetic flux as with conventional dynamo steel, on development of a magnetic field through the winding. When the materials are used as the stator and rotor in a generator driven by an electric motor, in which the current for driving the motor and generator is produced by the generator, only a fraction of the generated current is required for the drive, the excess current being usable for other purposes. Such current generation does not violate the law of energy conservation or other natural laws when the novel materials are used. ADVANTAGE - The materials produce lower magnetic force, at the same high magnetic flux, compared with conventional dynamo steel and can thus be used as stators and rotors in generators driven by electric motors to give a net current yield.

Title: Hand-tool machine with drill chuck - incorporates locking device preventing loosening of chuck jaws during operation
Inventor: REIBETANZ WILBERT DIPL ING
IPC: B23B31/173
Filed: 1990-02-23
Abstract: The chuck jaws are adjustable by a rotatable ring to the varying diameters of the tool shafts inserted in the chuck. This ring is unrotatably fixed to the base body of the machine by a securing socket which is under spring force and has an axially displaceable coupling. When the machine is in operation, an automatically operating slide member (21) with a slide surface (22,28) pushes the securing socket (17) from its non-locking position to that for locking. The inclination of the slide surface (22,28) is not larger than the angle of friction between the surface and the slide member (21). The slide surface has a recess in which the slide member is accommodated, and between it and the recess is an inclined guide surface (25,27).

Title: Conveyor, esp. for abattoirs and cold stores - has hooks pushed forward by friction with carriers attached to hydraulic cylinder and prevented from returning by ratchet system
Inventor: VIERE HANS
IPC: B65G25/06
Filed: 1990-08-15
Abstract: A conveyor has transport hooks or similar attachment elements (9), which are moved forward by drive system on carriers (10) along a conveyor rail made up of track sections (2). The drive system has at least one drive unit (3) with a moving element (4) which is coupled to a carrier drive element (10.1), and the movement of this piston during forward and backward strokes is transferred to the hooks by the carriers (10) associated with the carrier drive element (10.1). During a backward stroke, a carrier and carrier drive element moving can move relative to the hooks which are held in position. The drive element may be a hydraulic cylinder. The hooks are kept from moving backwards by at least one catch (7). This catch has one surface which is inclined to the direction of transport, and one surface which is at right angles to the transport direction, and the hooks can be deflected on the track sections (2) at right angles to the direction of transport so as to pass over this catch in the forward direction of motion. The catch (7) may be spring loaded and pivot about an axis orthogonal to the direction of transport. USE/ADVANTAGE - Used esp. for transport of carcasses in slaughterhouses and cold stores. The risk of food contamination due to leakage of lubricant, restricted conveyor path layout and the limited life of the chains, are avoided.
