Patent DE-2022673-A1 (DE)
Title: Kiln building element - for trolley support structures
Inventor: EICHHORN ROLF
IPC: F27D5/00
Filed: 1970-05-08
Abstract: Building elements for the erection of suitable support structures for ceramic kiln charges on kiln trolley platforms consist of vertical pillars arranged in rows. The pillars have grooved shaped cavities on the top for locating the horizontal double T profile beams placed across them. The depth of the cavities is pref. not greater than thickness of the T flanges. The reason for limiting the depth of the cavities is that the top of the T flanges are used for the support of cover plates which can be slid along the flanges and which are used for regulating the circulation of the kiln atmosphere over the charge being fired.

Title: Rotary piston engine - in which piston movement is transmitted to a concentric rotating centre shaft
Inventor: DOBO TIBOR LOUIS DE
IPC: F01C1/10
Filed: 1973-09-27
Abstract: A planet wheel and eccentric disc transmit the eccentric movement of the piston to the concentric rotating movement of the shaft. The piston is fitted with a radial surface shaped in relation to the housing to produce several recesses in the inner space between housing and piston at a distance from each other. These recesses include at least two separate combustion chambers each fitted with sparking plugs. There are fuel inlets and exhaust outlets and the radial surface of the piston is shaped to include projections which, during rotation of the piston, successively compress the fuel, push out the exhaust gases. The eccentric rotation of the piston causes a degree of co-ordination between the piston projections and the inner surface of the combustion chambers so that the fuel inside the combustion chambers is in a degree of max. compression when the sparking plugs start the combustion process.

This steel sheet pans can thus give very hgh galvanising productivities, equal temp. distribution being assured by adding a thermodynamically induced flow to the convective heat between inner and outer pan. The pan walls need not be supported on the sides and both pans retain their shape.

Title: Cable colour coding system has hot paint applied to hot strands - to speed drying in oven before twisting strands into cable
Inventor: RODERBURG HARALD
IPC: H01B13/34
Filed: 1973-11-24
Abstract: The cable coding system, for colour coding separate strands of a cable, marks the separate strands with different colour before they are twisted into the finished cable. The paint is heated under pressure (120 deg.C at 1.5 atmospheres) and applied to the strands by spraying whilst hot. The paint temperature on application is almost equal to the melting point of the strand insulation. The strand is warmed before the paint is applied. After coding the paint is dried by heating. The drying time of this process is relatively short since the paint and the strands are pre-heated to drive off the solvents in the paint more quickly.

Title: Automatic speed control for vehicle - with inclination sensor to increase traction and acceleration on slopes
Inventor: UEBEL HELMUT DIPL ING
IPC: B60K31/00
