Title: Radio link controlled beam direction - uses heterodyning of derived wave with fundamental in dipole port to obtain optimum aerial gain for directional operation
Inventor: MOERZ GUENTER DIPL ING
IPC: H01Q25/04
Filed: 1976-06-16
Abstract: A method is used for controlled beam direction using reflector aerials to balance out or compensate for level fluctuations in radio links. It is used specif. in directional radio and involves the use of readjustment of the aerial characteristics in micro-wave engineering. To obtain optimum aerial gain with maximum residual or internal losses, and at small expense, the method involves heterodyning a wave, derived from the hollows waveguides fundamental wave. The fundamental wave is generated in the driven dipoles port in such a way that an excursion of the maximum field strength of the exciting or driving source causes turning of the aerial lobe, the excursion being from the central axis of the driven dipole.

Patent DE-2634104-A1 (DE)
Title: Cable trolley suspended from rail - has spring loaded guide rollers to inhibit lateral movement
Inventor: KRUEGEL WERNER
IPC: B66C13/12
Filed: 1976-07-29
Abstract: In applications necessitating the use of suspended trolleys for supporting supply cables, for example as in the power supply for a travelling crane, rapid acceleration can cause lateral oscillation or yawing of the trolley. In turn this may lead to hammering of the rail making smooth running impossible under any circumstances. The yawing effect can be damped out by providing lateral guide rollers (9), normally below the main support rollers (6). These guide rollers are provided with a spring or elastic mounting which keeps the rollers pressed against the rail flange, and also absorbs some of the energy causing the yawing during accleration. With this modification the rail flanges are not subjected to hammering by the rollers and a long period of smooth running is ensured.

Title: Paper sheets cutting system for magazine pages - saves paper by reducing width of edge gripped by folding machine and tongues are used on edge
Inventor: KUEBER KLAUS
IPC: B42D15/00
Filed: 1976-10-29
Abstract: A sheet of paper (1) is delivered from a rotary printing press in the direction of the arrow (2). The sheet will be finally trimmed to the format indicated by the dotted line (3) after folding along the central line (14) to form the pages of a magazine. The edge (5) has two tongues (8) which provide a grip for the folding machine. The action of cutting the tongues (8) cuts recesses (6) in the edge (4) of the adjoining sheet so that each sheet has recesses (6) on one edge and tongues (8) on the opposite edge. This method of cutting the sheets reduces the width of the margins which are trimmed off when the sheet is folded and so saves about 2% of the paper.

Title: Protective interior coating for metallised transparent article - is applied by pouring molten mass inside to obtain required coating thickness
Inventor: HEGEMANN KLAUS DIPL ING
IPC: B05D7/22
Filed: 1977-02-08
Abstract: A method of protecting the interior of metallised transparent articles, particularly plastics articles such as water taps consists of melting the protective material, bringing it into contact with the metallised surface and maintaining it in contact until the required thickness of protective coating is obtained by the hardening of the mass. This substance can be poured in until this thickness is obtained, then the remaining molten material discharged. In the case of plastics articles, where the heat conductivity is low, the protective mass is heated to very little above its melting temperature.
