Patent DE-2017676-A1 (DE)
Title: Press frame with rectangular cross headand base sections
IPC: B30B15/04
Filed: 1970-04-14
Abstract: The base and cross head sections of the frame are provided with saw tooth like transverse profiles on two parallel opposite sides faces, and connected via tension plates, which have corresponding profiles to engage on the two sections. Additional pressure elements act onto the top and lower edges of each plate. The unprofiled side sections of the base and cross head, which project into the working space, also carry additional pressure elements to act onto the tension plates.

Patent DE-2019964-A1 (DE)
Title: Plastics moulding machine
Inventor: BROEMSER HANS
IPC: B29C33/20
Filed: 1970-04-24
Abstract: Machine for the prodn. of expanded plastics mouldings has at least two mould supports which can be moved together in a horizontal direction, one support being fastened to the machne frame and the other to the operating mechanism, and a locking mechanism which is arranged on one mould support and engages with the other mould support when the mould is closed. The pressure required for locking the mould supports is taken up by the locking mechanism, and is not transferred to the machine frame or operating cylinder. Consequently the operating cylinder and machine frame can have smaller dimensions.

Title: Yarn change - for circular knitters using cam disc or time clocks to trigger electro-magnetic contacts to ensure yarn overlap
IPC: D04B15/58
Filed: 1970-07-21
Abstract: The yarn change mechanism for a circular knitter uses process times with different time settings, or a constant rate cam disc to ensure that when the yarns are changed, the feed mechanisms are both kept in the feed position for a given time span to ensure a yarn overlap for 8 - 10 needles. The design takes into account the dead switching time on operating electromagnets for the yarn feeds, and prevents holes developing in the knitted fabric structure as a result of a yarn change.

Title: Interior brake warning light for car - operated by inertial mass to show driver if max retardation's reached
Inventor: BUSCH HEINRICH
IPC: G01P15/04
Filed: 1973-08-24

Title: Stretched filament mfg. process - has a draw unit for each fibrile split from thermoplastic film
Inventor: ULLRICH HEINRICH DIPL ING
IPC: D01D5/12
Filed: 1974-01-16
Abstract: Thermoplastic film is reduced to drawn fibriles using an individual drawing unit for each filament split from the film. The system allows a flexible production, to works a fine titre range to exploit the full capacity of the array. As the thermoplastic film is fed into the process, teeth split the film into individual fibrils, giving a quazi-continuous filament to be led off for stretching. The individual filament passes in a spiral round the heated surface of a braking roller before passing round the draw roller assembly, with a large roller and adjustable step roller. The filament passes between the draw roller assembly and the braking roller before being drawn off for winding. The stretch imposed is proportional to the speed of the rollers and the speed of film travel. The system is provided for all the filaments so that the film is reduced to a number of wound filaments according to the number of filaments split from the film. System allows flexible prodn. and uses full capacity of the array.
Patent DE-2403710-A1 (DE)
Title: Transmission for heavy vehicle - having gear box combined with differentials of multi-axle drive
Inventor: KLAUE HERMANN DR ING
IPC: F16H3/095
Filed: 1974-01-26
Abstract: The transmission layout of the multi-axle, heavy vehicle drive is simplified by combining the gear box, torque distributor and transverse differentials, into one housing, and lubricated and cooled by the same fluid. This reduces power losses and makes the transmission more compact and reliable. Excessive heating is eliminated by incorporating a water cooled clutch for the main drive control, or in the case of a tracked vehicle, water cooled torque brakes. The main clutch/brakes are dry plates type. The large suspension movements in heavy vehicles are then accommodated by the single drive shaft between the engine and the transmission assembly.
Patent DE-2426821-A1 (DE)
Title: Home beer or wine fermenting unit - comprises connected fermenting and storage chambers with separate gas pressure regulators
Inventor: POLLOCK JAMES RICHARD ALLAN
IPC: C12M1/12
Filed: 1974-06-04
Abstract: Beer or wine fermenting appts. consists of two chambers with a valved connection for transfer of the liq. from one to the other. One chamber is to contain a charge of filter aid material and yeast supported by a permeable support. The other chamber is for storage of the fermented and filtered liq. and has a valved outlet. Gas pressure regulating valves enable the pressure in the fermenting chamber to be kept higher than that in the storage chamber. Used esp. for small scale domestic appts. Unitary appts. produces a clear beverage carbonated with CO2 at desired pressure. Separate operations in different pieces of appts. are avoided, thus reducing risk of spoilage from excess carbonation, bacterial contamination and the like.

Title: Impact strengthened car floor section - has edge beams as external boundary with longitudinal slats absorbing side impacts
Inventor: DANCKERT HERMANN DR ING
IPC: B62D25/20
Filed: 1974-09-14
Abstract: Sheet metal car floors of usual design with indentations are not resistant enough against impacts coming from the side towards the vehicle. The present design proposes hollow longitudinal beams (1), on each side of the vehicle, connected by the floor (6) formed as a sheet with corrugations (7). The side beam (1) can be a U-section onto which a T-section (4) is welded with the leg (5) pointing away from the vehicle side. On an impact coming from the side this leg takes the greatest part of the shock, deforms and protects the material further inward against deformation. As an alternative the side beam can have the shape of a semi-circular gutter, the open end of which is closed up by a slightly dished plate.
