Title: Revolving freezer - with radially movable freezer plates
Inventor: KNODEL OTTO
IPC: A23B4/06
Filed: 1973-03-15
Abstract: A revolving freezer, esp. for foodstuffs, comprises a hollow shaft which conducts the refrigerant and a series of radial plate heat exchangers around the circumference at uniform intervals, which thus constitute freezing boxes between them.

Title: Aerial for very short radio waves for satellite communication - uses cassegrain-aerial with main- and sub-reflector for wide-area irradiation
Inventor: REBHAN WOLFGANG DIPL ING
IPC: H01Q19/19
Filed: 1973-09-25
Abstract: The plane aerial aperture enables simultaneous transmission of two or more approximately plane and homogeneous waves to increase the lower limit of the reception density in the service area. The amplitudes, phases, polarisation and direction of propagation are so chosen that in the propagation direction each of these waves reaches its lower limit of reception density in the area. The aerial may have the form of a Cassegrain-aerial with a main and a sub-reflector. The exciting system with its two or more exciting centres is located in or nearly in the focal plane of the sub-reflector. Each of the exciting centres produces in the aperture of the aerial at least approximately a plane wave.

Title: Hydraulic unloading of sugar beet - from wagons by coordinated motion of two jet sprays
Inventor: MESSERSCHMIDT WILFRIED
IPC: B65G67/24
Filed: 1973-10-03
Abstract: A hydraulic unloading system for sugar beet in railway trucks by water jets has one spray station with a control cabin from which the operator can direct the nozzle to the desired point inside the truck. a second station, one truck length removed, without a control station, is hydraulically coupled to repeat the movements of the first nozzle. To unload a large hopper wagon, the two nozzles can be coupled to carry out mirror-image motions. This saves manpower by enabling one man to unload two normal wagons simultaneously. In the case of large hopper wagons, it saves the necessity of shunting by half the wagon length.

Title: Cold starting burner for IC engine - has deflector cone surrounding fuel burner in suction pipe
Inventor: STEINER JOSEF DIPL ING
IPC: F02N19/08
Filed: 1973-11-23
Abstract: The cold starting burner is placed within the engine suction pipe and preheats the intake air by direct combustion. It has a fuel inlet nozzle at the apex of a deflector cone. Intake air flows round the outside of the cone, which is parallel to the surface of the cone formed by the fuel injected by the nozzle.

Title: Command initiation via radio channel - uses two or more simultaneous audio frequencies in speech/music channel
Inventor: MAISCH WOLFGANG DR ING
IPC: G08C19/14
Filed: 1974-03-07
Abstract: The proposed method uses two of five AF tones to allow 10 separate commands. If six tones are used 15 commands may be transmitted. If three of six tones are used 20 commands are obtained. The circuit may use ordinary speech transmitters and receivers. The tones may be transmitted via or after the microphone. The received tones may be picked off at the receiver output via a jack and fed to two bandpass filters followed by threshold stages. The outputs of these are fed to an AND-gate, the output of which is fed to one input of a second AND-gate and via a delay to the other input. If the dealy is 50 mS. a command output will only be given if both tones are simultaneously present for more than 50 ms. which will not be the case with speech/music.
