Patent DE-3005004-A1 (DE)
Title: Flame cutting of short slabs in continuous casting plant - using extra rollers in conveyor track so short cut pieces cannot fall through gaps between rollers
Inventor: HENNECKE FRANZ
IPC: B22D11/126
Filed: 1980-02-11
Abstract: In a first zone of the casting plant, cuts are made in the cast billet or slab; but the cuts only extend through part of the thickness of the slab. The slab then travels through a second zone in which cutting is completed. The cut pieces of slab are next pref. removed at the same speed, or faster than, the casting speed employed for the slab. The pref. plant includes a flame cutting machine clamped to, and moving with, the slab, and carrying several burners, so that several part-cuts can be made in the slab simultaneously. A conventional roller track can be used for cutting short pieces from a slab, by using extra rollers so the short cut pieces cannot fall through the track.

Title: Radar circuit for recognition of moving objects - uses charge coupled integrated semiconductor circuitry for comparison of echo signals
Inventor: BARDL ARTUR ING GRAD
IPC: G01S13/522
Filed: 1980-03-03
Abstract: The radar technology for the recognition of moving objects makes use of two charge transfer circuits (A,B), to produce a common output signal, whereby, the first echo signal received after being emitted by the transmitter is fed via a computing point (10) to the information input of one charge transfer circuit (A), and the second echo signal is treated likewise and fed to the information input of the other charge transfer circuit (B). An inversion of the stored information in one of these circuits is provided for. Thus, to produce an output signal, the two pieces of stored information due to the first and second pulses are combined, the coupled charge transfer circuits (A,B) forming a comparator for the two echo signals received from the moving object.

Title: Steel door frame for assembly on site - has separately made lintel and jamb posts joined by tongue and slot
Inventor: ALTSTETTER MANFRED ING GRAD
IPC: E06B3/988
Filed: 1980-05-23
Abstract: Steel door frames consisting of a lintel and two jamb posts are usually assembled by welding and then transported to the building site. In order to ensure that the frame retains its correct shape it is necessary to provide special equipment to protect it during transport and storage. These difficulties are overcome by making the lintel (1) and jamb posts (2) separately. Both members have similar cross-sections which are generally U-shaped. The lintel has a tongue (13) which projects downwards at each end and fits into a slot (21) in each of the jamb posts. Since the door frame is assembled immediately before installation on the building site, the lintel and jamb posts can be transported and stored separately so that much less space is needed.

Title: Warehousing system load handling mechanism - uses carriages, each with arms under load carrying surface, tilted to form load retaining stops
Inventor: BOHRER LOTHAR
IPC: B65G1/04
Filed: 1980-05-31
Abstract: The warehousing system with tiers of shelves carrying objects which can be stored in rectangular containers, uses loading and unloading carriages which are moved up and down vertical tracks adjacent to the shelves. Each carriage has a telescopic structure which advances and retracts a flat plate (8) forming the load carrying surface in front of a selected shelf to receive a load. Below the plate is a mechanism for locating the load during travel of the carriage. This consists of a pair of tilting arms (12,13) mounted on brackets with hinge pins (14,15) through them, forming the axes of tilt. When a load (4) is deposited on the plate, a pin (18) projecting upwards through the plate pushes a pair of arms downwards at the centre, so that their outer ends are lifted. These ends carry lugs (10) which are raised sufficiently high to act as stops for the ends of the load.

Title: Recirculating ball spindle and nut drive - uses spring fitting into suitably shaped groove around spindle as part of track
Inventor: KOUKAL ANTON
IPC: F16H25/22
Filed: 1980-07-28
Abstract: The recirculating ball spindle and nut drive, uses a spring (12) retained by the spindle to serve as the guide for the balls (19), the ends of the spring being secured. The spring, which is made of round section spring steel wire, can be retained in V section grooves around the spindle. In another form, the cross section of the spring wire can be shaped so as to fit into a rectangular section groove. In both cases the shape of the wire may also include concave grooves of larger radius than that of the surface of the balls. Another method uses a layer of plastics material which hardens after application to retain a round wire spring.

Patent DE-3104290-A1 (DE)
Title: Incoming-air and outgoing-air grating
Inventor: WILLENBROCK HANS DIPL ING
IPC: F24F13/15
Filed: 1981-02-07
Abstract: For the ventilation and air extraction of rooms, gratings are inserted into the incoming-air and outgoing-air orifices, in order to direct and guide the air streams. The labour and stock-keeping for the production of gratings of different sizes, with all the individual parts in a form ready for use, involve a high outlay. To reduce the labour for the production of different grating sizes and to lessen the outlay in terms of stock-keeping, there is proposed an incoming-air and outgoing-air grating which has slats, fastened to a frame, for directing the air streams, and in which the slats are combined to form prefabricated modules and can be inserted into the frames at a later date. Slat modules can be plugged into the frame and be held by a positive connection. Less common frame sizes can be produced in a short time and be completed with the slat modules. The slat modules consist of slat bars and holding bars which are put into the frame and which are secured against vertical displacement by bent-round retaining tongues.

Title: Connection for free-standing walls
Inventor: BEIER HUGO PETER
IPC: E04H1/12
Filed: 1981-02-11
Abstract: The invention relates to a connection for free-standing walls which can be easily assembled and dismantled and comprise individual wall parts. The wall parts have anchors which jut out at their corners and by means of which they can be pushed into joint-like connecting bodies. In order to plant the anchor in the connecting body, use is made of centrally arranged clamping screw which, via oblique surfaces, acts on at least one clamping body which can be radially displaced and, when tightening the clamping screw, can be pressed at the same time against all the plugged-in anchors. The result is a fixed clamping connection between the connecting body and the plugged-in wall parts. Consequently, the stability of the free-standing wall is increased and, moreover, through-passages, relatively large openings and the like can be spanned without additional supporting measures. <IMAGE>

Title: Process for conveying a fluid and hermetically encapsulated pump/motor aggregate for implementation of the process
Inventor: GRUBER FRANZ
IPC: F25B15/02
Filed: 1981-03-16
Abstract: For conveying the coolant/solvent mixture in absorption heat pumps, use is made of hermetically encapsulated pump/motor aggregates. Because the fluid drawn out of the absorber is in almost boiling state, it is possible that with minor temperature fluctuations vaporisation and thus undesirable cavitation can occur. This is avoided in that a part flow of the fluid to be conveyed is branched off from the suction chamber (12) of the pump (1) and brought into contact with heat-developing parts of the motor, e.g. by being conducted through a screw-shaped conveying groove (14) of the rotor (4) of the motor (2). <IMAGE>
