Patent DE-2538079-A1 (DE)
Inventor: SCHILDBACH WOLFGANG
IPC: B60P9/00
Filed: 1975-08-27
Abstract: When hay is conveyed by the vehicle, a superstructure (8, 9) is swung up; when green fodder is conveyed, the superstructure is folded together downwards into its inactive position. The superstructure has pivot points (7) on two vehicle side walls (5). The pivot points (7) are located at a distance (a) downwards from the upper edges (6) and within the walls (5). When the superstructure (8, 9) is in the folded-together position, it is located underneath the edges (6) and in the loading space. The operators therefore do not come into contact with the folded-together parts (8, 9) of the superstructure, thereby largely avoiding the risk of injury. As a result of the downward pivoting of the superstructure (8, 9) below the edges (6) of the walls (5), the predetermined height difference between the overall height of the vehicle with the superstructure swung up and with the superstructure folded together is maintained and the loading space for green fodder is enlarged. <IMAGE>

Title: Monolithic carrier catalysts for purification of exhaust gases - with positive gradient of active phase in flow direction
Inventor: VOELKER HERBERT M
IPC: F01N13/02
Filed: 1975-09-23
Abstract: Monolithic carrier catalysts for purificn. of exhaust gases from combustion waters, show a positive gradient in content of active phase in the flow direction. Longer life is obtd. since ageing and poisoning of the catalyst by impurities in the gases, e.g. lead, is concd. near the gas inlet. Efficiency is increased by presence of higher amts. of active catalyst where the concn. of combustible material is reduced and conversion is more difficult. In an example, a monolithic carrier 150mm long contains the catalyst in concn. increasing from 0.2 to 0.5% in the first half and from 0.2 to 0.74% in the second half. Using exhaust gas at 720 degrees C, conversion is 98% for CO and 78.71% for HC. After 100 h. use, values are 98.04% and 74.74% respectively.

Title: Pneumatically actuated clamp for machine tool - has hydraulic intensifier to exert high clamping force on workpiece
Inventor: ARNOLD FRANZ
IPC: B25B1/10
Filed: 1976-06-14
Abstract: The clamp for holding the workpiece of a machine tool is operated by rotating the handle (25) which drives the cylinder (12) through a spring loaded catch in the end cap (28). When the jaws (4, 7) come together due to that rotation of the screwed shaft (9) in the fixed nut (5a), further rotation of the handle overcomes the spring catch so that the end cap (28) rotates through a small angle relative to the cylinder (12). This motion opens an air valve so that air pressure acts on the piston (14). The piston rod (15) is pushed into the hydraulic chamber (12a) creating a very high hydraulic pressure which acts on the piston (11a), shaft (10) and jaw.
