Patent DE-2222866-A1 (DE)
Title: Fibre reinforced shell mould - for moulding shells and for glueing them together
Inventor: ZORN ERWIN
IPC: B29D22/00
Filed: 1972-05-10
Abstract: Prodn mould for shell-like components by glueing together hollow, glass fibre-reinforced laminates, e.g. for making fibreglass boats containers etc. comprises female mould components with flanges along their joint lines; there are >=1 access holes into the mould and into the shell structure moulded in it to give access for glueing the half-shells together.

Title: Front wheel drive for rotary or turbine engine - having power unit parallel to front axle with single coupling gear for compact layout
Inventor: KLAUE HERMANN DR-ING
IPC: B60K5/04
Filed: 1973-09-03
Abstract: The rotary engine is arranged in parallel to the front axle and drives an epicyclic gear box and a torque converter set in a line across the car. The output from the power unit is by a centrally mounted gear driven through coaxial shafts between the torque converter and the middle of the unit. The gear drives directly onto a differential system for a compact layout which does not affect the steering movement of the front wheels. For a turbine the epicyclic reduction gear is arranged coaxially on each side of the turbine to drive directly to the front wheels. The cooling fan is set with a vertical axis to blow over the turbine.

Title: Self boring plug with inner cone - inner cone wall is forced against outer wall of plug
Inventor: SCHAEFERS HEINRICH B
IPC: F16B13/13
Filed: 1973-09-28
Abstract: The plug or dowel has the advantage that it does not rely solely on the tension force between the plug and the side of the hole for its load carrying capability. As the plug is inserted an internal conical hole is bored with a lesser cross section than the cone itself at the end of the hole. The cone forms the spreaders of the plug into a conical shape to form an anchor for the shaft. The cone is connected to the plug shaft when it is in the fully home position.

Title: High-tension transmission line insulators - of conventional type interspersea with some doped with zinc oxide as flashover gaps
Inventor: FOITZIK RUDOLF DR ING
IPC: H01C7/12
Filed: 1973-12-06
Abstract: A high-tension transmission line is equipped with ceramic insulators which suspend the conductors and insulate them against earth. A part of the insulators are of the conventional type and another part with the same dimensions and mechanical strength is designed as flash-over gaps. The latter insulators are fitted with a core or with an outer sheath of doped zinc oxide. This saves the cost of the purchase and accomodation of special flash-over gaps.

Title: Easily-starting DC motor - has light weight plastic armature with nickel-iron alloy as core
Inventor: HAMANO KIYOSHI
IPC: H02K23/58
Filed: 1974-01-29
Abstract: The D.C. motor has a plastic armature with three pole shoes and three coils. The armature core is formed by a highly permeable nickel-iron alloy. Constructing the armature in this way ensures that the motor starts easily even at low supply currents. The plastic armature poles reduce the armature inertia thus allowing it to start more easily. The armature is enclosed by two semicircular permanent magnets mounted on a support ring that fixes to the motor housing. The spring brushes protrude radially through the housing and rest with their ends on the collector.

Title: Process and apparatus for continuously rolling sheet material - has automatic cut off and re-loading by air blown loop of severed web
Inventor: ZUBER GERHARD DIPL ING
IPC: B65H19/28
Filed: 1974-05-13
Abstract: The sheet material passes over driving roll to the stock roll. When the roll is full a new empty roll on a swinging frame is pressed against the material on the driving roll. By braking the roll and application of an air blast, a loop doubling back on itself is created. By operation of an air blast together with, if necessary, a spray of glue from the nozzle, the loop is caused to move and so to wrap the material onto the new roll. At the same moment a cutting knife severs the sheet. The air blast and cutting knife are now swung away and the full roll removed and the new roll swung into position to take its place.
