Title: Web esp in screen printing machine - is registered by being pulled temporarily into oblique position
Inventor: BLACK JAMES A
IPC: B41F13/02
Filed: 1974-05-28
Abstract: At each printing station the web (W) passes over suction devices (54, 72) which pull a local length of the web backwards and towards one side into a position oblique to the main path of the web. The angle taken up by the local length and its longitudinal register are determined by markers (T1, T2) previously adhered to the underside of the web and whose rear edges abut register fingers as the length is pulled back. This reduces register errors due to arbitrary wandering of the web to the right or the left. After registration a roller (62) and a screen arrangement apply the print.

Title: Pressure limiting valve with hydraulic control - is fitted with differential piston with adjustable spring and hydraulic resistance
Inventor: BACKE WOLFGNAG PROF DR ING
IPC: F16K17/04
Filed: 1974-07-02
Abstract: A differential piston moves against the force of an adjustable spring and there is an integral 'half bridge' type hydraulic resistance. The latter is a combination of an inlet and outlet throttle with a branch pipe to a pressure reservoir. The valve is claimed to have the advantage of quick response to a sudden pressure change making it particularly suitable for use as a safety valve. The inlet throttle is acted on by an intermediate pressure through the valve piston. The throttle has a defined non linear characteristic depending on the flow characteristic. The outlet resistance throttle is constant. To achieve the required flow curve there is a groove and several blocking out points with breadth or depth that declines in a step function.

Title: Method of charging batteries and accumulators - charging is stopped when charging voltage increase stops
Inventor: BECHTOLD LEANDER
IPC: H02J7/00
Filed: 1975-01-28
Abstract: The charging system for individual accumulators or banks of such is intended to provide optimum charging, avoiding damage to the batteries and achieving the charge in the minimum time. The charging time, during which the full charging voltage is applied across the batteries is determined and controlled by an auxiliary voltage charging a capacitor to some value set automatically within fixed limits. This auxiliary voltage is always less than the charging level. The main charging voltage is removed using a relay circuit when its level falls below that of the capacitor, this being supplied from a constant current, variable frequency pulsed source.

Title: Mobile rotary mixer with improved operation - having single spiral baffle with pronounced concavity in outlet section
Inventor: WEDLER KLAUS DIPL ING
IPC: B28C5/42
Filed: 1975-02-20
Abstract: Rotary drum mixer, esp. mobile mixer has system for filling, mixing and emptying consisting of a single spiral element. In the mixing region this has approximately the inclination normally associated with such mixers. In the inlet and outlet conical section, it has a smaller inclination but a greater effective height. In approx. 2/3 of this length, commencing from the drum inlet, the element has a pronounced concave section, and in the area near the lower end of the inlet hopper it is very markedly concave to such an extent that it forms an extension of the hopper. In the mixing region it has a height of about 200 mm. To improve the mixing other baffles can be inserted in this area. To speed up discharge, a short section of a second spiral of 180 degrees to the first can be used near the drum opening. For use with large mobile mixers to improve the utilisation of such mixers, i.e. speed up the emptying operation and improve the mixing time. This is achieved by the concave element which discharges the mixer very much faster and thus reduces turnround time at point of delivery.
