Title: Versatile insulated layered building slab - has ventilating channels between intersecting layered beams on layered panel
Inventor: SCHWINN GEORG
IPC: E04C2/284
Filed: 1979-08-14
Abstract: Insulating material is sited between covering layers in a building panel or slab, with cladding or load bearing functions. There are at least two superimposed insulating layers, one with covering layers in the shape of a plan-parallel panel. The other layer combines with covering layers to form a beam. A series of these beams are mounted on the panel, at intervals, with cross-beams, comprising insulating and covering layers between them. The panel and beams form the building slab with lengthways beams thicker than cross ones, leaving room for ventilating channels between the former.

Title: Plastic injection moulding process - moulds items in regular stages and joins them together in moulding operation
IPC: B29C45/00
Filed: 1979-09-25
Abstract: Process produces plastic mouldings in multi-section injection- moulding tools, the mouldings being continuously injected in regular stages, and joined together in the moulding operation. The portion injection-moulded in the previous operation is joined to the new one by injection on, in or round it. A portion can be injection-moulded in the closed tool, which is then opened at the level of the joint seam on the moulding, this being then moved lengthwise out of the tool until only a small portion remains in the latter. The tool is then shut again and the next item moulded, the remaining portion of the previous one being enclosed and secured in a recess in the new one.

The measuring is carried out on a unit which generates an electric AC field in the sample and has a measuring appts. for the dielectric constant. The container is mounted in the unit such that a shaking mechanism can set it into vibrations. The natural frequency of both the container and the sample may be detected. The shaker is an electromagnetic type with a core and coil.

Inventor: SEILER KARL-HEINZ DIPL ING
IPC: H02K7/09
Filed: 1980-02-20
Abstract: The motor compressor is pref. in the form of a reciprocating compressor, sprung-mounted in a capsule suitable for a refrigerator.

Title: Automatic mortar spread on three sides of building blocks - involves successive conveyance lengthways and sideways for double and single face application
IPC: E04G21/20
Filed: 1980-05-17
Abstract: Coating is automatically applied to three sides, and output is much faster than that achieved with laborious hand work, in a process for spreading mortar on building blocks to be used in masonry. Blocks (3) are individually conveyed, one after the other, from an assembly in a row, in a direction at right angles to the row, to two supply points where prepared mortar is applied to the top surface and one side face. They pass on to a supply point where mortar is applied to the front face, and are then conveyed to the wall being erected. it pref. involves two moving carriers (24,25) gripping the block on the end (A) of a conveyor belt (2) pre-set for one block at a time, thrusting it first across and then parallel to the belt, below a container (4) taking mortar from a mixer, with first two bottom holes and then one.
Patent DE-3025982-A1 (DE)
Title: Water-level sensor for sterilising autoclave - feeds stored water only when adequate supply available
Inventor: TASCHNER WOLFGANG
IPC: B01J3/04
Filed: 1980-07-09
Abstract: The water-feeder vessel contained in a water-storage container above the pressure chamber of a sterilising autoclave can be connected to the storage chamber or the pressure chamber. The feeder valve is closed at the top and has a pipe extending vertically above the storage container water level and connected to the feeder-vessel interior. In this pipe is a water-level sensor element, smaller in cross-section and hence more sensitive to level changes than the feeder vessel. The sensor may be of float type, but preferably incorporates electrodes forming part of a resistance or capacity measuring unit. Water is only fed into the pressure chamber or positive establishment of adequate amts. rather than using a timed programme, which is unreliable. A large electrode surface can compensate for the low conductivity of the distilled water commonly used for sterilisation.

Patent DE-3046584-A1 (DE)
Inventor: JUERGENSEN HEINRICH
IPC: G02B27/00
Filed: 1980-12-11
Abstract: Positional errors are corrected for a light beam which is deflected point and line-wise across a scanning surface by a polyhedral rotating mirror. For each mirror surface, the positional errors are measured in the line direction and perpendicular thereto at a plurality of measuring points oriented in the line direction in the area of the scanning surface. Correction values are generated which, during simultaneous error measurement, are changed until the positional errors are compensated by means of correction elements. The determined correction values are stored and are read out for continuous correction during the actual operation synchronously with the mirror surfaces simultaneously located in the beam path. Light deflectors are employed as correction elements. Employing the rotating mirror in a recording arrangement, transit time elements controlled by the correction values are disposed as correction elements in the signal path of the image signal for the correction of the positional errors in the line direction. If the image signal is stored, the frequency of the read clock can alternately be changed as a function of the correction values. The method is very accurate so that, in particular, errors caused by uneven mirror surfaces are corrected.

Title: Method for the environmentally acceptable removal of burning low-temperature carbonisation coke (semi-coke) on opening the furnace doors in coking plants
Inventor: HOELTER HEINZ ING GRAD
IPC: C10B33/00
Filed: 1981-02-11
Abstract: When the coking furnace doors, in particular of horizontal-chamber coking furnaces, are opened and the coke cake produced settles, the smouldering coke or the semicarbonised coal which falls out is collected, quenched and cooled, its smell is neutralised, and it is also conveyed to a central collecting point.

Title: Plate or the like for holding a number of various tools and similar objects
Inventor: WAECHTER KLAUS DIETER
IPC: A45C5/00
Filed: 1981-04-23
Abstract: The invention relates to a plate (1) or the like for holding a number of various tools (23) and similar objects (16). The objects are held in a removable manner by one or more elastic bands (7) running transversely to the main axis. The bands (7) are anchored to the plate (1) by holders (6) at distances corresponding to the tools or the like in the respective size and shape, the bands (7) being guided in the holders (6). The holders (6) have a slot (8) for guiding the bands (7). The position of the holders (6) on the plate (1) can be changed for adaptation to various objects. The slot (8) in the holders is arranged at an angle of up to 90 DEG , preferably at an angle of 90 DEG , relative to the plate (1). The bands (7) are thereby held edgewise relative to the surface (9) of the plate. This offers the advantage that tools in particular can easily be inserted in place again. In addition, extremely flexible guidance of the band (7) on the plate (1) is also possible in a zigzag shape. <IMAGE>
