Title: Tiltable road roller undercarriage - has platform with two sets of wheels for road transportation
Inventor: HORSTMANN DIETER
IPC: B60P1/00
Filed: 1974-11-05
Abstract: To enable the road roller (1) to transport quickly from one workplace to another a platform (5) is lowered in front of the roller, with two pairs of wheels (4). When the roller is moved onto the platform it loses contact with the road surface and it rests on the two wheel sets. The platform is fitted with an inclined edge. When the roller reaches this edge, the platform tips over around the axle (15) of the wheels, which then coincide with the axle of the roller, until stop (16) comes to rest against the btoom edge of chassis (8). In this position the arrangement is in equilibrum and the roller can be transported using the two sets of wheels, without the risk of the roller slipping-off the platform.

Inventor: SIEVE GREGOR
IPC: E06B9/78
Filed: 1975-04-07
Abstract: The function of the lever mechanism is to control the lowering of a roller shutter. The activating strap is led through at the bottom, between a two-armed swivelling clamp lever and a fixed abutment. This lever is pressed by the tractive force, exerted on its inward-pointing arm by the strap holding the shutter up, so that its outward-pointing arm is against the abutment in the clamp position holding the strap in place. A one-armed activating lever (4) is set on a swivelling mounting near the clamp lever (3), with a cam (4a) projecting across the inward-pointing clamp lever arm (3a) on the side facing the clamp lever. This cam presses the lever arm downwards when the activating lever swivels, thus releasing the clamping action on the strap. The cam may be in the form of a lug set eccentrically to the swivel axis of the activating lever and circular or oval or cylindrical with a flattened side.

Title: Mixer rotor for gasifying fluids, esp. sewage - has vanes setting up double flow, inclined to vertical plane
Inventor: STIMM PETER DIPL ING
IPC: B01F15/00
Filed: 1975-11-27
Abstract: A rotor on a driving shaft enclosed by a diffusor pipe for mixing air or fumes into a fluid in the open or in large vessels, esp. for aerating sewage, is designed like a double flow pump wheel. Radial vanes are arranged on a disc so as to set up an upper gas flow and a lower liquid flow. In the direction of rotation, the vanes are curved backwards to a point extending beyond the circumference of the rotor disc, and they are inclined relatively to their horizontal axes so that, esp. in the zone of the free ends, the lower edge of the vane lags behind its upper edge. The design intensifies the mixing of the larger size gas bubbles rising through the fluid and thus increases the efficiency of the gas supplied. The vanes create not simply a radial flow but also an axially downwards flow increasing the length of the paths followed by gas and fluid.
Patent DE-2600894-A1 (DE)
Inventor: YEE KIM SHEE DR
IPC: C23C28/02
Filed: 1976-01-12
Abstract: The components located in a reducing atmosphere at high temperature and produced from nickel-based alloys containing carbide formers are protected against high-temperature carburisation by a protective layer which consists of tungsten or molybdenum. When applying the protective layer, an interlayer of pure nickel of a purity greater than 99% by weight is first applied to the base material, and subsequenly the protective layer of tungsten or molybdenum is applied. The adhesion of the two layers to the material is improved by a final diffusion-annealing treatment. The purpose of the nickel interlayer is, on the one hand, to improve the adhesion of the outer protective layer to the base material and, on the other hand, to prevent decarburisation of the base material due to reactions of the carbon contained therein with the outer protective layer.
