Title: V -mounting for elastic vehicle suspension - with separate flanges bolted together for axial force which is even across suspension
Inventor: NIEMANN GERHARD ING GRAD
IPC: B60G7/02
Filed: 1975-06-03
Abstract: The U-shaped mounting bracket serves to support one end of a suspension element with an elastic clad bearing shaft. In order to ensure even padding on both sides of the shaft, when the bolt is tightened, the two sides of the mounting frame are attached to separate base plates which are positioned over each other. As the securing bolt is tightened the two base plates move over each other until the mounting holes line up, so that the complete assembly can be fitted to, the vehicle. The bracket ensures an even padding force on the suspension.

Title: Rotatable internal knee joint prosthesis - permits easy manipulation during implantation and simulates normal knee movement
Inventor: FISCHER WOLFRAM
IPC: A61F2/38
Filed: 1975-09-06
Abstract: A knee joint prosthesis allows bending in the direction of walking through at least 120 deg. from the extended position of the leg, and bidirectional rotation in a direction perpendicular to that of bendings. When the leg is extended, no rotation can occur, but when it is bent at 90 deg., rotation of 10-15 deg. is allowed, and is controlled by two guides and an intermediate sliding counter-member. Rotation is possible (a) symmetrically in both directions and proportionally to the angle of bending, (b) symmetrically in both directions and non-proportionally to the angle of bending, (c) symmetrically and proportionally, (d) asymmetrically and non-proportionally. A sliding shield may be connected releasably to the thigh portion as required.

Title: Central heating system controlled by outside conditions - uses monitoring and comparison system to regulate fuel supply
Inventor: KNOLL ALOIS DIPL ING DR
IPC: F24H9/20
Filed: 1976-07-13
Abstract: A central heating system operated to adapt to the time of day and/or the time of year, alters the predetermined time intervals. After a second set of predetermined time intervals, the heating is cut off and if a predetermined support temperature differs from the normal temperature the ambient temperature is controlled by comparison. During the second time intervals, the heating is reversed so that the normal temperature is reached as quickly as possible. In cold external conditions, the support temperature is raised, and is controlled from two fixed points. For outside temperatures which require the maximum heating up during the first time intervals, the support temperature is adjusted to the estimated normal temperature.

Inventor: SCHMIDT PAUL PROF DR ING
IPC: B07B7/086
Filed: 1976-10-29
Abstract: The centrifugal wind sorter has a substantially cylindrical sifting chamber (1) wherein the sifting air and the fine material is axially discharged through a central opening in the end wall (5) of the chamber and a suction pipe (13) which covers the axial extension of the chamber is linked to the latter by inlet openings (15) divided over the area of the pipe with the free surface of these openings decreasing in the direction of flow. This design considerably reduces resistance i.e. by more than the power of ten e.g. from 1000 to 88. It is pref. to distribute the inlet openings unevenly over the perimeter of the pipe so that a part of the area remains closed. The division of holes at the outlet end is preferably so small that the build up of dust formed by the centrifugal force reduces the internal cross-sectional area of the pipe by up to 25%.
