Title: Absorbent material impregnation - brings fluid to compressed material for distribution through it by air extraction
Inventor: MOTITSCHKE LOTHAR DR
IPC: D06B5/12
Filed: 1977-10-13
Abstract: The process is impregnate an absorbent material, by inserting it as a stack into a fluid-filled vessel, compresses the material before treatment. The fluid is introduced to the vessel and it passes through the material by extracting air from the stack. The system provides a simple process and simple equipment to ensure that an absorbent material is fully impregnated.

Title: Machining welding or surface treating using laser beam - with heating augmented by arc struck to zone of beam incidence
Inventor: STEEN WILLIAM MAXWELL
IPC: B23K26/348
Filed: 1978-03-30
Abstract: Workpiece is treated by directing a laser beam onto it, and striking an arc from an electrode the zone heated by the beam. Pref. the heated zone extends through the workpiece and the arc is struck to the surface opposite to the beam; or arcs may be struck to both the beam-incident and opposite surfaces. The incident zone may be moved relative to the workpiece. The workpiece may be surface alloyed by applying a suitable material prior to heating as above with scanning of the whole surface, or the process may be used for cutting drilling or welding with one or more gas jets directed as the heated zone to disperse the generated vapour plume. The gas may be reactive. The use of supplementary arc heating, possibly aided by exothermic reactions involving the gas jet, provides greater thermal energy input to the workpiece than can be achieved by increasing the laser power. Machining is thereby accelerated and weld penetration improved.

Title: Casualty and surgical bandage - fits sliding clasp fasteners over joint and wraps with fixing material in predetermined position
IPC: A01G1/06
Filed: 1978-04-26
Abstract: The system holds two live parts stationary in a predetermined relative position, being typically for a graft onto a tree or to join two broken bone parts together. It uses fixing material bridging the join and held in place by a bandage so as to secure the parts in place once it has hardened. After alignment of the two parts (3, 5, 4, 5) two or more divisible sliding-clasp fasteners (2) are fitted over them parallel to each other and at angular intervals, with their halves in the closed position, and secured to the parts concerned. The fastener teeth are then covered by easily removable sheet, and the fasteners and the surfaces of the parts lying free between them are bandaged, with the fixing material in plastic distorting condition, the material being then allowed to harden.

Patent DE-2836185-A1 (DE)
Title: High viscosity paste injection syringe - with thin long cylinder and beaded flexible piston rod
IPC: A61M5/31
Filed: 1978-08-18
Abstract: A syringe for the injection of high-viscosity pastes consists of a thin (under 10 mm) cylinder, e.g. with a length of 10 to 100 times the dia). The piston rod is made fo a thin flexible rod on which beads of slightly smaller dia. than the cylinder bore are arranged to prevent the piston rod from kinking. The beads are held between the piston at one end and a stop at the other end. An application gun with a trigger has a catch which fits between the beads and feeds the piston forward. The very thin and long cylinder allows a high enough unit pressure to be exerted on the paste to ensure its trouble free injection. It is long enough to hold the entire dose for one injection. Pref. the cylinder is of 'Teflon' (RTM).
Patent DE-2838209-A1 (DE)
Title: System using magnetic energy produced by wire - heats water surrounding wire by use of magnetic molecular influence instead of direct electric heating
Inventor: HOFFMANN PAUL
IPC: H05B6/00
Filed: 1978-09-01
Abstract: The system has two parallel wires inside a container holding water (or oil or similar) insulated by glass wool or similar. A current is passed through the wires. A magnetic field is produced. It is claimed that energy is released from the magnetic field and causes the water to heat up more rapidly than would be the case if electrical heating only were used. An example is given where 300 litres of water is heated 36 degrees C from 20 to 56 degrees C. This would normally require 26 kW for a specified time but the device uses only 19.5 kW, as a result of the magnetic field effect.

Patent DE-2848427-A1 (DE)
Title: Energy generating dynamoelectric machine - uses repelling force only by aligning like-sign poles and converting these forces by rotatable arrangement of electromagnets
IPC: H02K53/00
Filed: 1978-11-08
Abstract: The dynamoelectric machine does not operate on the principle governing electric motors, but switches off the attractive forces of electromagnets to permit a full play of the repulsive forces, which are thus effective for energy extraction. The system improves the supply power and generates no exhaust gases, radio-active fall-out, or any other pollution of the environment. To attain the desired effects, the plug poles of electromagnets are arranged opposite each other and during approach repel each other. The same applies to the minus poles so that the attractive forces are completely eliminated. The repelling provides a full force which can be doubled when the electromagnets are horseshoe-shaped. The repelling forces are converted into movement for energy extraction. For this purpose, at least one side of the electromagnet carriers must be rotatable. This is possible by permitting current flow through the electromagnet coils only during moments of equal sign poles approaching each other.
Patent DE-2848527-A1 (DE)
Title: Fuel treatment behind carburettor outlet IC engine - use vortex producing component to improve combustion by increasing mixing of air and fuel
Inventor: LANG LUDWIG DIPL ING
IPC: F02M29/06
Filed: 1978-11-06
Abstract: An insert between the carburetter and the engine contains flow diverters which produce small vortices in sections of the flow. The number, size, and spacing of the diverters can be varied. The vortices impart a centrifugal acceleration to the fuel-air mixture which in turn results in a centrifuging action of the mixture. As a result of this and because of the different specific weights of oxygen and nitrogen, the mixture is enriched in oxygen at the periphery of the vortices. The outer layer from the vortices is led axially into the cylinders through a slowly rotating inner stream at lower pressure.

Title: Powered sliding lift doors arresting mechanism - has support for arresting unit moved into active holding position at end
Inventor: NIEMEIER HANS ING GRAD
IPC: E05F15/649
Filed: 1979-03-27
Abstract: The system is used for controlling doors in lifts. It stops driven units for the doors sliding in a straight line in their closed and/or open position. In the event of drive failure, the doors can be moved by hand, by overcoming retentive force. Use is made of a support member (12) and arresting member (14), one on a fixed carrier and the other on the moving part. When the door is moved into an end position, the arresting member is transferred through the support member, against return force, to an active seting. Here it tends to hold the moving part permanently in the end position defined by the stop (34, 36) Construction is simplified, with non-self-locking drives acceptable.
