Title: Flexible rubber axial and radial suspension - has separate axial and radial r cushions with axial sleeve bearing
Inventor: TRACHTE KURT
IPC: B60G7/02
Filed: 1973-08-25
Abstract: The design is particularly for independent wheel suspensions for motor vehicles. The advantage of the design is that high pivot angles without additional high axial loads can be accepted. Both the axial rubber suspension cushions (18) are separate from the radial rubber cushion (4A/4b). An axial sleeve bearing (17) fits between the axial collar and the appropriate axial cushion (18). The radial cushion (4a/4b) and/or the outer sleeve (13) are so designed that the pivot supports in the two operating planes have differing spring characteristics. The spring characteristic of the pivoting support is symmetrical in the horizontal direction to the centre axis and progressively increases towards the centre. The spring characteristic in the direction of the force of gravity is less than that in the horizontal direction.

Title: Automatic determination of quotient value - particularly exposure time of photo-reproduction systems depending on paper sensitivity and light intensity
Inventor: HOLZHAUER BERND
IPC: G03B27/80
Filed: 1974-03-09
Abstract: The process and equipment relate to determining automatically a quotient value from two variables and are applicable particularly to exposure time in photoprinting, depending on light intensity and paper sensitivity. The process consists in integrating to a saw-tooth voltage a voltage magnitude proportional to the nominal value of the quotient, comparing it with a voltage magnitude proportional to a counter value of the quotient and measuring the time taken for the saw tooth voltage to reach parity. The time taken is used for control purposes and/or as a standard for the quotient. The equipment has a timing stroke generator with low frequency stroke whose output signal is fed through a gate circuit to a forward-reverse counter. After this has counted back and zero value decoder has responded, the start unit initiating the process is switched off. The forward-reverse counter is then reset by a digital store through a data selector to its initial value.

Title: Bivalent facsimile signals transmission method - only a selection of picture points is scanned and transmitted
Inventor: MUSMANN HANS GEORG PROF DR ING
IPC: H04N1/411
Filed: 1974-04-05
Abstract: Intermediate points are derived from the transmitted points. A decision circuit tests both at the sending and receiving end, whether an intermediate picture point can be relatively safely reconstructed from the transmitted points. Points recognised at the sending end as relatively reconstructable are not transmitted. Points which cannot be safely reconstructed are stored and transmitted in the gap between the last picture point in a line, and the first point in the next. In the receiver picture points transmitted in a line are stored in a first series store with parallel tappings, and points transmitted in the gaps between the lines are separately stored in a second series store.
