Title: Extrusion of metal blocks after induction heating - with reversal of the blocks to ensure that the end with least oxide enters the extruder
Inventor: RETHMANN WERNER DIPL ING
IPC: B21C33/00
Filed: 1976-08-06
Abstract: The metal blocks are first fed into an induction oven in which they are heated. The heated blocks are then pushed onto a carriage with a rotating platform. The carriage tips over at the end of its travel and drops the block on a cross transport which feeds the blocks into the extruding press. As the end of the block emerging from the oven has oxidised more than the rear end, the block is rotated through 180 degrees. The rotating platform on which the metal block is first placed has a knurled edge or edge with other high friction finish with which the edge of the platform engages to allow rotation.

Title: Plant for lake water latent heat exploitation - has heat pump with compressed air apply to melt water under ice sheet
Inventor: SCHRAMMEL HUBERT
IPC: F24V50/00
Filed: 1976-08-21
Abstract: The heat pumping plant extracts thermal energy from water in lakes, and utilises its latent heat of fusion, released as it solidifies. During thawing, dehumidified air is forced into the melting water in the reduce volume between the ice formation and the melt water surface. Rapid breaking away of the clinging ice layer is obtained by mechanical vibration of the cooling elements. In this way the enormous heat potential of the surface waters can be exploited all the year round by the heat pump principle, and the ground heat energy is made available by altering the ice: water proportion in lakes and ground water.

Title: Sterilising water with chloramine - produced in a water stream by first injecting chlorine then ammonia before being introduced into the water to be sterilised
Inventor: SCHWEINSBERG HERMANN
IPC: C02F1/76
Filed: 1976-09-15
Abstract: Sterilisation of water, esp. drinking water, uses chloramine which is produced by separately injecting chlorine and ammonia in a 2:1 wt ratio into the water. The injection is effected by first injecting a side-stream of the water (which acts as the driving side-stream of the water (which acts as the driving fluid for injectors) with chlorine and then with the ammonia and metering this inoculated water into the water to be sterilised. Use of soft water as the driving fluid for the injectors is obviated. There is always sufficient HCl present to counter deposits forming in NH3 injector. There is no possibility for the chlorine to react with the ammonia except in water (which absorbs the heat and slow reaction).

Title: Vibration mode analysis for vehicle structural components - involves eigen frequency stimulation, local amplitude measurement, and arithmetic processing
Inventor: SORGATZ ULRICH DR ING
IPC: G01M7/08
Filed: 1978-04-05
Abstract: A method of determining the vibration modes of a component, partic. for vehicle structural componenets, involves measurements at frequencies of interest, esp. component eigen frequencies. It is implemented rapidly, accurately and economically with convenient components. Vibrations are stimulated by the application of local shocks whose effect is measured and produces a reference signal with one of the frequencies of interest. Maximum vibration amplitudes at the frequencies of interest are measured at different points. Each measurement signal is divided by the reference signal. The quotients constitute position- and frequency- related measurement outputs.
