Patent DE-2618128-A1 (DE)
Title: Bullet retardant polyamide - produced by activated anionic polymerisation of monomeric laurin lactam
Inventor: HAUPT GUENTER ING GRAD
IPC: F41H5/04
Filed: 1976-04-26
Abstract: Bullet-retardant material for armoured military and civilian vehicles consists of cast polyamide which has been produced by an activated anionic polymerisation of monomeric laurin lactam. A high percentage of amorphous material such as glass or carbon fibres is desirable, as is a Vicat B softening point of under 183 degrees C (161-168 degrees C). This results in considerable weight savings if used in combination with thinner special steel armour. The vehicles have better mobility and cross-country performance. The good castability of the polyamide results in greater freedom in the configuration of the castings. The smaller heat conductivity is an advantage where infrared homing systems are used. The better damping properties reduce the nuisance of vibrations.

Title: Hydraulic shock absorber for torque meter - has flow gap maintained between piston and cylinder walls by frictionless captive rollers
Inventor: BITSCH JAKOB ING GRAD
IPC: F16F9/16
Filed: 1976-05-26
Abstract: The double acting hydraulic shock absorber is used esp. in machines for measuring the torque of production machinery. The faces between piston and cylinder wall ensure good and uniform sealing of the chambers. The damping characteristics are determined by the shape of the damping piston. The cylinder and piston sliding faces are not in contact and have profiles which increase flow resistance. The damping chambers are connected to each other with overflow holes (8). The piston is guided by three guide rollers concentric within the cylinder. The rollers avoid stiction which might upset the readings of the meter.
Patent DE-2630663-A1 (DE)
Title: Dyeing fibres in form of a compressed bale - held against an outlet in a dye chamber through which dye is circulated (SW 16.5.77)
Inventor: PLACK LUDWIG
IPC: D06B5/14
Filed: 1976-07-08
Abstract: Fibres are dyed in the form of a compressed bale by introducing the bale into a dyeing chamber through which dye is circulated via a return circuit. The dye is removed from the chamber via an outlet against which the bale is pressed by e.g. a clamp device. Dye is pumped through the base until the correct colour is achieved, and the bale is then removed, dried and separated into loose fibres. The appts. is cheap and a reduced quantity of dye fluid is used, thereby reducing the cost of the dyeing operation.

Title: Printing stamp has forme turned through ninety degrees - when moved from rest into printing position, via shaft with sprocket engaging chain with ends spring connected
Inventor: SCHNEIDER GEORG
IPC: B41F17/24
Filed: 1976-11-23
Abstract: Printing stamp has a forme (27) supported on a horizontal shaft (16) itself supported for a vertical motion whereby the forme is lowered from the rest into the printing position. A sprocket (17) secured to the shaft is engaged with a chain (18) whose ends are connected by respective springs (21, 41) to the frame (1) of the stamp. One of the springs (41) is stiffer than the other and the arrangement is such that when the shaft is lowered the forme turns through 90 deg..

Title: Continuous feeding of materials into pressure zone - using liquid seal and continuous belt conveyor
Inventor: SCHROEDER HANS JUERGEN
IPC: A23L3/04
Filed: 1976-12-17
Abstract: Method involves a system of communicating vessels of which at least one is the pressurised enclosure. This then has an inlet and outlet passage connected to the lower part of the vessel. This is then filled with a fluid medium liquid or gaseous of greater density than the surrounding atmosphere. One side of the pressurised enclosure is formed from the surface of the fluid. This is esp. oil or water. Some form of conveying system is provided between the inlet, the enclosure and the outlet. Used esp. for continuous treatment of food materials e.g. for pressure cooking or treatment to preserve certain qualities. Continuous or quasi-continuous processes using treatments under pressure have had to rely on mechanical seals. This tends to damage the food. The system described avoids this.

Title: Printing unit for paper processing production line - has ink feed element extending only over central portion of inking roller
Inventor: BRANDT ECKHARD
IPC: B41F31/06
Filed: 1976-12-18
Abstract: The ink feed element is for a printing unit in a paper processing production line, e.g. book or paper pad mfg., and facilitates a defined coating of a selected zone for the inking roller. The element acts directly on the surface of the roller but extends only over a central part of its length leaving the end regions clear. The element comprises an elastic wiper blade whose upper surface is pressed against the lower rotating surface of the roller. In a second design a tube (122) is used whose circumference is separated from the roller surface by an inking gap. The ink is fed through the tube and out through holes (116) in its surface. The emerging ink strikes a baffle plate (124) mounted on the side of the tube furthest from the roller (102).

Title: Automatic stitching of curved side sections to upholstery covers - using multi-needle sewing machine with feed clamps on travelling carriage
Inventor: SCHAEFER HERMANN
IPC: D05B11/00
Filed: 1977-01-15
Abstract: In the automatic stiching of curved side sections to upholstery covers, these are inserted flat in multi needle sewing machines and stitched through parallel seams along the cover with cheesecloth and then the loops formed are filled with strips of wadding. The side sections, covers and cheesecloth are fed to the needles and the free ends of all the layers are fixed in a feed clamp, so that the ends of the side sections are fixed exactly to the point from which the seam runs. Then the machine is started and the first parts of the layers to be stitched are fed under the needles and the side sections are kept under light tension. The clamps are released shortly before reaching the needles, whilst the clamps for the side sections are released last. Process saves fixing and guiding the side sections to the covers and allows automatic stitching.
