Title: Plastics pallet container for liquids - is tightly fitted in steel plate stacking shell with welded cover and bottom
Inventor: SCHUETZ UDO
IPC: B65D25/34
Filed: 1976-08-25
Abstract: Plastic pallet container for liquids includes an enclosable filling and outlet opening and is surrounded by a close fitting framework to enable the container to be stacked on top of a similar container. The framework consists of a plate shell with welded on cover and bottom and is attached to a conventional flap pallet by claw pallets. The shell of the framework is provided with openings which form an access to the filling and outlet opening of the container. In one of the four rounded vertical edges (18) of the plate shell (2) are located sight openings (19) for controlling the filing level of the container. The sheel of the framework is produced from a rectangular cut out of steel plate which is bent into a tube and longitudinally welded. The resulting plate tube (10) is pulled over a stretching press (11) provided with stretching jaws (12) of corresponding shape as the small sides (13) of the plastic container. When the stretching jaws (12) are moved apart the wide sides (16) of the plate shell (2) are stretched until their material is yielding and they are cold formed. Subsequently the sight openings are stamped out in the rounded edge.

Title: Low slung railway wagon loading deck - has transverse movement allowed using manual device coupled to locking mechanism for swinging out guide pin
Inventor: FILK EBERHARD
IPC: B61D3/04
Filed: 1976-10-26
Abstract: The cross displacement mechanism is for the loading deck of a low-slung railway wagon, mounted on a guide wagon at each end which is led on a bogie frame.

Title: Tritium concn. detector with two parallel chambers - for passage of different gas flows to eliminate background effects
Inventor: FRIEDRICH WIELAND ING GRAD
IPC: G01T1/178
Filed: 1977-05-27
Abstract: Detector comprises a thin-walled metal tube divided into two chambers by a thin partition foil. Each chamber contains a wire typically acting as anode, and the gas contg. the tritium passes along the tube. A voltage pulse producted across the wire and the tube is proportional to the ionisation caused by the beta emission resulting from tritium breakdown. The partition is impermeable to beta radiation of the type resulting from tritium particle breakdown; a sample of the gas to be investigated together with another gas such as methane which can be ionised is conducted through one chamber, while a gas which can be ionised such as methane and/or butane is passed through the other chamber. The effect of the partition is to eliminate the beta radiation caused by tritium breakdown from one of the chambers but to allow it to act in the other chamber; as a result background radiation effects can be sepd.

Patent DE-2730608-A1 (DE)
Title: Spark ignition IC engine - has inlet valve timing to make compression and expansion ratios different
Inventor: TROST CHRISTIAN DR MED
IPC: F02B41/04
Filed: 1977-07-07
Abstract: The engine has a piston reciprocating in a cylinder with cam operated inlet and exhaust valves. The inlet valve opens (I) at TDC. It remains open for the whole of the suction stroke (II) and does not close until the piston has started to return (III) upwards. Part of the charge is thus returned into the suction manifold and only part of the stroke used for compression. After ignition by a spark at or near TDC expansion takes place over the whole of the working stroke of the piston. The expansion ratio is thus > the compression ratio. This enables more work to be extracted from the gases for a given compression ratio and thus increases the efficiency.

Title: Measurement of crystalline faults in magnetic material - uses analysis of noise signal generated by Barkhausen effect
Inventor: TIITTO SEPPO DIPL ING
IPC: G01N27/82
Filed: 1977-10-15
Abstract: A method of measurement of faults of application generally to magnetic materials (i.e. ferromagnetic, antiferromagnetic, ferrimagnetic and antiferrimagnetic) is based on the analysis of the noise signal generated by the Barkhausen effect. Factors controlling the generation of the noise signal are frequency and amplitude of the applied magnetic field, the phase of the magnetising cycle (point on the hysteresis curve) at which the noise is measured and the inherent damping of the noise signal in the material (eddy current damping). Analysis of the character of the noise signal yields information on lattice faults such as dislocations, precipitates, inclusions and cracks. Analysis may be based on the pulse amplitude, length or repetition rate, or the autocorrelation function of the noise signal.
