Title: Device for introducing and adjusting reinforcing inserts
Inventor: FISCHER GUENTER
IPC: E04C5/16
Filed: 1985-10-16
Abstract: In the production of reinforced gas concrete, the introduction and adjustment of the reinforcement is particularly important because it has to observe three requirements: firstly, the precise position of the reinforcement in order to satisfy the statics, secondly a stable captive fastening of the reinforcement during the expanding and maturing process in order to expose the intersection zone, and thirdly the exclusion of any damage to the corrosion protection of the reinforcement. Prior-art introduction and adjustment devices achieved the object only by use of reinforcing cages, the webs between the two mats of the cage being necessary for fastening. The device according to the invention has a way of achieving the object by which the requirements of the reinforcement in gas-concrete elements can also be fulfilled when using single mats.

Title: Process for determining the mouldability of a shapeable softened material
Inventor: FEISTNER KARLHEINZ
IPC: C03B11/16
Filed: 1986-01-16
Abstract: The invention relates to a process for determining the mouldability of a shapeable softened material in a cyclically operating pressing device, which process can be used, for example, in the pressing of glass articles or in the prepressing of glass gobs to be further processed in such cyclically operating pressing devices, in which a heated glass gob is introduced into a mould. The aim is to make the pressing process more uniform and thereby to save material and energy and, in particular, to obtain an improved quality, in particular in the case of diffusors for motor vehicle headlamps. For this purpose, according to the invention, in a cyclically operating pressing device with a transducer for an initial position of the pressing operation and with a further transducer for a final position of the press plunger or for the end of the pressing operation, the time between a time point, which is always the same, at the beginning of the pressing operation is determined and is compared with a reference time. With the aid of the difference between the two, parameters such as, for example, the composition of the moulding material, the temperature, inter alia, are influenced with the object of improving the pressing properties of the moulding material.

IPC: B60C11/00
Filed: 1986-05-07
Abstract: The invention is based on a pneumatic vehicle radial ply tyre with two tread belts separated from one another by means of a central circumferential groove. In order to improve the wear pattern and to reduce the wear of the tread overall, on the basis of the invention the two tread belts have, under normal operating pressure of the pneumatic tyre, in each case a crowned tread area outside the ground contact point. In order to be able to achieve this goal better, in the non-inflated state of the tyre, the two tread belts each have an essentially conical outer face which has its smallest diameter in the region of the circumferential groove. When the tyre is inflated the two crowned tread areas are then produced.
