Title: Stacking of roof tiles on kiln cars prior to baking - where each row of tiles standing on edge is divided into two sections resting on each other
Inventor: WOLF WILLY
IPC: F27D3/00
Filed: 1978-12-22
Abstract: A row of gps. of tiles is located on the kiln car platform between the front and rear ends of the platform; each gp. extends transversely across the platform, and consists of a vertical stack of several layers. All the tiles in each layer stand on edge; and the longest dimension of the tiles is parallel with the direction of travel of the kiln car. Each layer of tiles is divided into 2 sections of equal length extending across the kiln car platform; and one section is placed on each side of the central, longitudinal plane of the platform so the 2 sections in one layer are supported by each other. The tiles stand on edge so their centres of gravity force them to slope upwards towards the central longitudinal plane of the platform. Even when the tiles are made of clay with high shrinkage, they can be stacked on the platform via a machine without using any central or side supports, so labour and heating energy are saved, and distortion during baking is avoided.

Title: Agitator-mixer - incorporates protective sheath allowing bearing to be situated below liq. surface bearing support to be lowered to depth
Inventor: STREICHER MAX
IPC: C02F3/20
Filed: 1979-05-26
Abstract: A mixer agitator comprising a shaft supported in a bearing situated below the level of a liq. and mounted so as to rotate in a tube or arm with bearings carried from above downwards has the mounting covered with a tube-sheath such that it is fluid-tight, even when sliding, against liq. penetration. The mixer-agitator is partic. applicable in the treatment of aggressive and abrasive liquids e.g. liq. manure, waste waters, sandy mixtures and others in which it is essential that the support be protected. A bearing situated below the surface of the liq. cannot be attacked by liquid during operation. It is sufficient that the outer surfaces be corrosion resistant, while the inner parts can be of other suitable materials. It is also possible to use high speeds of rotation without the bearing suffering. Only the dimensions of the bearing support determine how far the latter can be submerged.

Title: Subscriber monitoring in electronic telephone exchange - has circuits to block selected subscribers if power supply load limit is reached
Inventor: LECHNER ROBERT DIPL ING
IPC: H04Q3/00
Filed: 1979-09-26
Abstract: Through a suitable interface (S) the central controller (ZST) of an electronic exchange monitors the state of the individual subscriber line terminals (TS1,..TSx). This monitoring checks whether the line impedance is high or low and establishes whether the line is not in use or whether the receiver is lifted and a low impedance switched in. The limiting resistors (R1,..R4) are controlled by electronic switches (1p,2p) operated by a relay (P) controlled by the exchange. If, for economic reasons, the exchange power supply (ZB) cannot feed all the subscribers in the low impedance state then some sort of overload protection is necessary. At times of high power supply demand the exchange controller (ZST) can order some subscribers terminals to remain in the high impedance state regardless of whether the associated instrument (Tl1,..Tlx) is indicating the desire to make a call. Similarly incoming calls are also blocked. The power demand is thereby limited.
