Patent DE-2412779-A1 (DE)
Title: Improving flowability of filled plastics before injection moulding - by vibration to generate thixotropic effect from subsidiary fillers
Inventor: MENGES GEORG PROF DR ING
IPC: B29C45/72
Filed: 1974-03-16
Abstract: Thixotropic plastics, contg. a high proportion of filler materials, are plasticised before they are injected into a mould, by introducing a charge of the ready-mixed material into a chamber immediately upstream of the injection nozzle and producing an oscillating shearing action in the material, until it is sufficiently flowable to be injected. The method is used for injecting plastics contg. a high proportion of inorganic fillers. e.g. glass fibres, additional fillers such as silicates, carbonates, talc or the like being added to produce the thixotropic effect. The resultant reduction in the viscosity and increase in the flowability of the material is virtually independent of temp., so that the method is especially advantageous for thermosetting plastics, where a high temp. is undesirable before injection.

Title: Inert gas supply for ship's tanks - uses banks of bottled gas to supplement or replace exhaust gas supply
IPC: B63J2/00
Filed: 1974-06-11
Abstract: The fuel or cargo tanks of the ship are fitted with an inert gas supply which covers the surface of the fuel with inert gas to prevent explosions. The gas is usually derived from the exhaust gases from the engines, after being filtered. When docked, especially when discharging fuel, the engines are stopped and cannot supply gases.

Title: Low power loss electric traction - with some or all of field coils replaced by permanent magnets
Inventor: ALTENDORF JENS-PETER DIPL ING
IPC: B60L11/18
Filed: 1974-06-21
Abstract: The DC traction motor is controlled via its field coils, as these require only a friction of the armature current. In order to reduce current losses to a minimum the field coils are partly replaced by permanent magnets, with field windings to reinforce the permanent magnetic field. Alternatively the field coils are completely replaced by permanent magnets with variable air gaps to alter the magnetic loops and control the motor speed via mechanical linkages to the hand controls. The system provides an efficient electric traction for battery driven vehicles.
