Patent DE-2523368-A1 (DE)
Title: Crushed malt or barley mash homogeniser - with tangential inlets for hydrodynamic stirring action
Inventor: LENZ BERNHARD
IPC: C12C7/06
Filed: 1975-05-27
Abstract: A homogenizer for washing crushed malt or bareley, specially for grist mills, is based on a hydrodynamic stirring action of the mash. This is achieved by introducing the mash flow in the homogenizer tank below the fluid level and in a tangential direction. Several inlets can be distributed symmetrically around the periphery in the same or several different horizontal planes. This homogenizer system combines construction simplicity with an increased throughput. The intake of air into the mash is eliminated and the homogenizer is not susceptible to mechanical damage.

Title: High pressure rubber hose coupling connector - is fitted by pushing or pulling smooth mandrel through connector
IPC: F16L33/213
Filed: 1975-07-22
Abstract: The connector for hoses of flexible material e.g. rubber is used at high pressure. The end of the connector inserted into the hose bore has smaller dia. than the hose bore and this inserted end is subsequently expanded to make a firm connection. The connection is able to resist high internal pressure and high axial forces and retains its sealing characteristics. The connector inserted part is expanded after insertion radially from inside by a mandrel (14) pushed into the section. The mandrel can be inserted before insertion of the connection and expansion is carried out by pulling the mandrel outwards. The flow cross section through the connector is maintained after the mandrel is pushed or pulled through the insert section (2).

Title: Coaxial pipe joint - has external rings of hook tape on ends with which common coupling tape engages
Inventor: BRABANDER JEAN LEON DE
IPC: F16L37/00
Filed: 1975-08-02
Abstract: The joint is particularly for use between plastic pipe sections of constant diameter, and comprises an external ring on the end of each of hook tape, i.e. a tape with hooks or a tape with loops in it, as used for the "Velcro" R.T.M. type fastener. A further tape hooking into engagement with both the ring tapes is placed round them simultaneously. The tapes can be glued to the pipe ends.

Title: Semiconductor crystal pulling system - using heat shield near fused zone for lower temp. gradient
Inventor: KELLER WOLFGANG DR
IPC: C30B13/28
Filed: 1975-12-18
Abstract: In a crucible-free zone melting process, the seed crystal with the recrystallised bar is pulled down from a fused zone at the semiconductor stock bar. The fused zone is maintained by an inductive heating coil. A heat shield which can be moved up to within a few mm from the coil to surround the recrystallised bar is made of a thermally stable heat insulating material. Keeps the temp. gradient beyond the fused zone low. The heat input required is reduced to an optimum value. The lower internal temps. result in a longer working life of the expensive equipment for large semiconductor bar pulling.

Title: Drying, smoking, roasting and steaming foodstuffs, esp. meat, sausage - in closed circuit without environmental pollution
IPC: A23B4/052
Filed: 1976-01-02
Abstract: An installation for processing foodstuffs, esp. meat, sausage and mixed prducts, works in a practically closed circuit. There are fans to circulate the processing medium and conditioning plants for the prodn. and maintenance of the required degree of humidity and temp. in the processing atmosphere. All known drying, smoking, roasting, baking, steaming, ripening and scalding processes can be carried out in the temp. ranges between 0 degrees - 300 degrees C without deterioration of the quality due to altered odour and flavour constituents. There is no need for the venting of large quantities of gas up flues and there is no build up of pressure in the system due to smoke prodn. or of loss of pressure through redn. in the humidity. The installation makes it possible to run efficiently with the minimum of energy and the amt. of water extracted, i.e. the redn. in weight of the goods, can be measured if required without interrupting the process, so that the best results can be obtd. and reproduced. The necessary gas throughput for faultless smoking is reduced to 0.4-0.6% of that required in conventional installations. The gases vented to atmosphere are free of smoke and odourless. The consumption of smoke generating material is reduced generally and the propagation of noise through other floors of the building by chimney stacks and to the outside through ventilator openings is eliminated. Energy requirements are reduced, environmental pollution is eliminated and weight losses in the product reduced to the absolute minimum.

Patent DE-2602878-A1 (DE)
Title: Electric furnace lining wear distribution - utilises magnetic field generated for deflecting arcs to protect lining
Inventor: STENKVIST SVEN-EINAR
IPC: F27D11/08
Filed: 1976-01-27
Abstract: The wall masonry lining in an electrical three-phase arc furnace is induced to wear evenly by a magnetic field arrangement symmetrically about the electrodes which intersect the electric arc in the furnace chamber above the furnace charge. This ensures uniform distribution of the wear caused by the electric arcs. This keeps the wall lining costs low. The magnetic field in the furnace chamber is directed through the lining of the furnace bottom and through the furnace charge. The electric arcs are deflected alternately to both sides by the magnetic fields which are built up by the current flowing through the electrodes. The polarity of the magnetic fields intersecting the arc may be held constant. Alternatively, the polarity of the magnetic field periodically intersecting the arc is reversed at a frequency which is less than half of the frequency of the electrode current.

Title: Furniture connecting joint holding chipboard panels - has rixing bolt locked in position by obliquely held washer
Inventor: SIELEMANN WOLFRAM
IPC: F16B12/20
Filed: 1976-04-22
Abstract: The chipboard panel (12) is provided with a serrated plastics bush (14) which has a screw thread to receive the bolt (16). The panel (10) has a cylindrical housing (18) fitted in a recess which is connected to the edge of the panel by the slot (28).
