Patent DE-2743560-A1 (DE)
Title: Screw spindles operated by worm gear drive - connect adjustable rolling cylinder mounting bridges
Inventor: GIPPERICH THEODOR
IPC: B21B31/04
Filed: 1977-09-28
Abstract: A horizontal set of rolling cylinders is located between two mounting bridges. Two pairs of vertical tie bars provide the adjustable location for the mounting bridges and thus control the radial gap between the cylinders. The bottom end of each tie bar has a thread which is located inside a worm gear wheel. A common drive shaft with a worm between each pair of worm wheels operates the setting of the rolling cylinder gap. Hydraulic spacer units between the mounting bridges provide the reaction force for the tie bar tension.

Title: Friction coupling for screw press - has diaphragm equipped with friction linings and flexing between clutch plates when engaged
Inventor: DISCHLER HELMUT DIPL ING
IPC: B30B15/12
Filed: 1977-10-07
Abstract: The friction coupling is fitted to a screw press and is operated by an hydraulic cylinder. It has a metal diaphragm (6) fixed to the rotating shaft (5) and provided with a distance piece (9) each side of the shaft. Screws (11, 12, 13) are used to prevent any axial or rotational movement. The diaphragm is rectangular, being reduced near the outer ends (21, 22) to form emplacements for a strip of friction material each side, these being square to the shaft axis. One clutch plate (1) moves axially inwards to engage the clutch, the pressure flexing the diaphragm against the other clutch plate to complete the drive.

Title: Cleaning flat filter by backflushing with compressed air - fed through blast pipes which are moved by power cylinder acting on lever arm to step=up stroke
Inventor: WENTE HEINRICH ING GRAD
IPC: B01D46/00
Filed: 1977-10-11
Abstract: A flat frame filter is cleaned by backflushing the filter area by compressed air from blast pipes. The blast pipes are guided in a structure on the sides of the frame and are reciprocated across the filter area by a power cylinder. To magnify the stroke of the power cylinder, say in a ratio fo 3 to 1, the blast pipe structure is linked to the filter frame by a lever and the power cylinder acts not directly on the structure but on this lever.

Title: Boxless sand moulds consisting of cope and drag - made on two station moulding machine with ample space for core insertion
Inventor: OHLE NORBERT
IPC: B22C11/10
Filed: 1977-10-14
Abstract: The machine has a press station (a) for moulding the drag, which is moved along one roller track (1) through a turnover station and onto a second roller track (2) used for core insertion and returning the drag to a second press station (b) in which the cope is made. The drag, still in its moulding box, and contg. one or more cores, is moved into station (b) so the cope in its moulding box can be aligned above the drag. The two parts of the mould are then pressed out of their boxes as one assembly and travel along an exit track parallel with tracks (1,2). Tracks (1,2) pref. form the two long sides of a rectangle and are connected by two short roller tracks which complete the rectangle. Adequate space is provided for inserting cores in the drags, but the two press stations (a,b) can be located close together.

Title: Ringer solution injection device - with non-return valves in pipes to syringe and heart catheter for better sterility
Inventor: UNTERBERG RALF
IPC: A61B5/028
Filed: 1977-12-23
Abstract: An injection device for Ringer solutions during measurements of the blood circulation through the heart of a patient with a heart catheter includes a pipe system for a direct connection of catheter and infusion flask, with a branch to the hypodermic syringe.

Title: Hops feed for brewing copper - with program controlled descending and ascending endless conveyor
Inventor: THOMASCHKI CLAUS DIPL ING
IPC: C12C7/20
Filed: 1978-03-31
Abstract: Hops are introduced into a brewing copper in containers, attached to an endless conveyor. A descending and ascending loop of the conveyor dips into the wort. A proximity switch cuts off the conveyor drive before the leading container reaches the fluid level. When the hops are washed out, the spent containers are moved on and flushed out while new hops are introduced. This contributes to the automation of the brewing process and ensures a controlled dissolution of the hops. The dangerous manual removal operations are eliminated.
