Title: Video signal time errors correcting circuit - is used for TV signals played back from recorder and has pulsed store in signal path
Inventor: SCHOLZ WERNER DIPL-ING
IPC: H04N5/953

Title: Cylinder lock with core with key channel and axial locking features - is designed not to be opened by sensing internal locking elements
Inventor: BOEVING EGON
IPC: E05B27/08
Filed: 1973-10-25
Abstract: The axial holding features project into the key channel and the axial tumbler members are connected to radial locking elements. The latter components project into a radial groove in the lock housing cylinder. The components of the lock are relatively large and rubust. Preferably the locking elements house rhombic cross sectional projections running in a slanting longitudinal direction. The cylinder lock with locking features ensures that the lock cannot be opened merely by sensing the internal elements. This feature makes the lock burglar proof. It is necessary that the actual features are correctly aligned and only then can the cylinder lock be rotated.

Title: Mined and quarried material handling system - uses crawler tracks on machine chassis to drive conveyor belts
Inventor: STEINBACH ADOLF
IPC: B65G63/02
Filed: 1973-11-05
Abstract: The material from the working face is transported and processed by mobile machines. The processing machine or the conveyor discharge are mounted on or above mobile crawler-tracked chassis. When these latter are stationary, the top run of the crawler track drives the conveyor belt, pressed down onto it by the weight of the material. Where a processing machine produces commodities of different characteristics from the same material, it can be used in conjunction with a crawler chassis operating in either direction. The track can be of the plate type, working in a frame which is lifted and supported clear of the ground, the conveyor belt running round it in guides. A hopper can be provided above the track, with a bottom opening roughly of the same area as the track top run.

Title: Rotary magnet with excitation coiled core - shaped so that effective pole surface varies with angular distance
Inventor: PASTUCH KARL HEINZ
IPC: H01F7/13
Filed: 1973-12-21
Abstract: The rotary magnet has a core and an armature enclosed by an excitation winding. An air gap exists between opposing poles faces of the core and the armature. At least one salient pole is formed on the armature and core and the air gap between the latter is constant. The armature is fixed to the shaft. Each of the armature's or core's poles is shaped and arranged so that the pole face acting on the magnet and tending to rotate it changes along the pole length. The disadvantageous influences of a variable air gap are avoided and an influencing and calculating of the turning moment is possible over the complete turning angle of the magnetic shaft.

Title: Radiator for hot water central heating - is equipped with reverse circulation fan to increase heat output
Inventor: SCHOELL GUENTER PROF DR ING
IPC: F04D17/12
Filed: 1974-03-20
Abstract: A conventional sectional low pressure hot water radiator is fixed to a wall. A frame is held in front of the radiator by brackets clipped to the radiator. The frame carries a propeller type fan which is directly driven by an electric motor in the hub of the fan. The fan has two separate sets of blades, an outer set being concentric with an inner set and fixed to the shroud ring of the inner set. The blades are set in opposite directions so that the inner blades propel air from the room onto the radiator and the outer blades pull air off the radiator into the room. This sets up a forced circulation across the radiator which increases the heat emission.
