Title: Heat exchanger drum for bulk materials - has cooled driven runner track segments made up of series of short segment links
Inventor: LACHNIT FRIEDRICH DIPL ING
IPC: F16H49/00
Filed: 1974-08-20
Abstract: Heat exchanger drum for the thermal treatment of bulk materials at high heating temperatures, which has runner rings to transmit a rotary motion where the runner rings form one piece with the drum by being welded into the outer wall. Cooled, driven runner track segments are fitted to each hot runner ring and for a short time these lie on the running ring via a roller bed.

Title: Tractor seat with adjustable lateral tipping - with double action hydraulic support ram with manual control valve
Inventor: RASMUSSEN LARS JOERGEN
IPC: B60N2/39
Filed: 1974-09-03
Abstract: The tractor seat is mounted on a pivot axle set longitudinally in the vehicle. It is prevented from tipping sideways by a double action ram between seat and floor. The two sides of the ram are closed by a shut-off valve linked to a manual lever by a spring loaded linkage. If the tractor is driving along a slope the driver operates the lever to release the ram and tilts the seat to the desired position with his feet, before the lever is released to lock the setting. A safety device monitors the inclination of the tractor and gives a warning if the set amount of tilt is exceeded, which is possible if the driver is in an upright position where he cannot 'feel' the tilt.

Title: Speed regulator for car - with accelerator pedal returning force increased if set speed exceeded
Inventor: TIXIER MICHEL
IPC: B60K31/18
Filed: 1974-09-18
