Title: Hydrodynamic retarder with hydrostatic transmission - has single heat exchanger and shunt valve to disconnect torque converter during braking
Inventor: KUHN WALTER DIPL ING
IPC: F16D65/78
Filed: 1975-12-20
Abstract: The hydrodynamic retarder is supplied with fluid from the same pumps as the hydraulic torque converter and is connected to a common heat exchanger by a full flow shunt valve. This reduces the system complexity and provides a fast response retardation, with the heat exchanger already under pressure when braking begins. The shunt valve diverts the full flow pump output to the retarder, and dumps its output through the heat exchanger, during braking. At the same time the torque connector runs free, with its output still connected to subsidiary circuits e.g. lubricating circuit.
Patent DE-2559666-A1 (DE)
Title: Cross country ski with keel shaped undersurface - has off centre apex with different inclinations for waxing
IPC: A63C5/04
Filed: 1975-12-29
Abstract: The skis for cross-country skiing have a keel-shaped underside, and the two inclined faces (30,38) include an angle of more than 90 deg. By placing the apex of this angle off the centre line of the ski, two faces of unequal width and inclination are obtained. Since mainly the inside faces of the skis are loaded when skiing uphill, climbing wax is applied to these surfaces. When skiing downhill or along flat tracks, the two outside faces of the skis carry the skiers weight. Thus wax which reduces frictional resistance is applied to these inclined surfaces. It is therefore possible to combine the two basic requirements of cross country skis.

Title: Exhaust gas afterburner for IC engine - has perforated plate and refractory wall in path of gases
Inventor: LEISTRITZ HANS KARL DR
IPC: F01N3/05
Filed: 1976-03-11
Abstract: Exhaust gases enter the afterburner through a central tube (11) and are ignited in a combustion space (10) by an ignition element (4). Their direction of flow is reversed by a target wall (29) at the end of the combustion space (10) and the burning gases flow through an extension zone (12, 13, 14). From this they pass into a final combustion zone (27) through a cylindrical sieve like plate (33) and impinge on a thermally insulated target wall (31). This breaks the flow of gases into a large number of small streams which are brought together again on the surface of the wall. This process aids combustion and counteracts the effect of sudden changes in exhaust flow which would otherwise result in incomplete combustion.
