Title: Force measurement ring with overload protection - using annular protection rib centrally placed in measurement annulus
Inventor: BROSA ERICH
IPC: G01L1/22
Filed: 1979-10-02
Abstract: The force measurement ring is applicable to a relatively low measurement range and is provided with a high degree of overload protection. The inner stabilising ring (1) has edge supports (9) forming an annulus and approximately centrally positioned overload protection ribs (2). The ribs have gaps enabling the symmetrical positioning of radial strain gauges. The edge support ribs (9) are welded together (8). When the measurement range is exceeded by the applied zone the overload ribs (2) come into contact with each other. Compensation strain gauges are positioned between the edge support and overload rib and are equally spaced about the circle. The measurement ring assembly (1,4,6) is held together by screws or clamps.

Patent DE-2941872-A1 (DE)
Title: Machine for making sausages with synthetic skins - has bath to moisten skin immediately before filling
Inventor: KOLLROSS GUENTER
IPC: A22C13/02
Filed: 1979-10-16
Abstract: A sausage making machine uses a long tube of synthetic material for the sausage skins. The synthetic skin is unwound from a reel and guided by rollers through a water bath. The skin then passes between rollers which form circumferential ridges to give the skin a caterpillar-like appearance. The skin is then pressed over a tube which fills it with sausage meat. Moistening the skins immediately before filling obviates the risk of the growth of harmful bacteria; and incorporating the bath in the machine reduces the size of the installation.

The upper sides (25) of the main guide tubes (13,14) facing the underneath of the table top (2) of the support tube (20,21) are mounted in a common plane thereby supporting the intermediate plates over their entire length. The fastening plates (29,30) which fix the ends of the telescopic tubes to the main plates are each mounted on a guide tube (26,27) which are longitudinally displaceable in the support tubes (20,21) and can be drawn out beyond the outer end sides (31) of the main guide tubes (13,14).
Patent DE-3007156-A1 (DE)
Title: Control system for electronic musical instrument - compares data register contents with address register via read-write memory
Inventor: WEISS WERNER ING GRAD
IPC: G10H1/18
Filed: 1980-02-26
Abstract: The control system has a multiplexer connected at its output via a channel to a device that shuffles or packs the binary words. An identifier is connected by its address output to an address register and by its data output to a data register. A comparator compares the contents of the data register and the address register (via a read/write memory). The advantage of this arrangement lies in reducing the number of transmission channels so that free-space transmission (e.g. IR, ultrasound etc.) can be employed and as a result reduces the number of cable connections employed.

The carry signal is also fed to the S input of an RS-Flip-flop. The R input comes from the output of a second operational amplifier (24) whose negative input receives a reference voltage, and whose positive input receives the output of the first operational amplifier and is biassed by a transistor (26) which is biased by the NOTQ output of the flip-flop. The Q output is 01Dedwithaclocksignal(32)todrivetheclockinputofan Up-down counter. The up-down control is fed by the output of the second operational amplifier. The counters outputs are fed to a third d-a converter (30) to the reference input of the first d-a counter. The clock signal is also fed via a switching circuit (33) and a switch (34) to the clock input of the first counter.

Title: Pruning shears with spreading spring between handles - has plain and looped handles with abutting inner edges and brake contg. self contg. system
Inventor: LEIHE OTTOMAR
IPC: B25G1/10
Filed: 1980-08-13
Abstract: The scissor type tool, such as garden secateurs, has two arms (5,6) connected by a hinge pin (1). It has a plain gripping handle on one arm (5) and a handle with an elongated finger loop on the other arm (6). In cross section, both handles are roughly T-shaped with the narrow stems projecting inwards towards each other. The stem of the looped handle has a protuberance near the top, acting as a stop to ensure that a gap is left when the handles are closed. When the two blades (2,3) are closed, their centre crosses the centre line of the two handles at an acute angle. Close to the pivot point is a locking cap (10) fitted with a locking spring which is automatically returned to its locking position when the handles are closed.

Title: Drawing-on rubber tubing onto curved mandrels - using centrifugal force generated by rotating disc or spinning drum
Inventor: GRONAU JOACHIM DIPL ING
IPC: B29C53/08
Filed: 1980-08-16
Abstract: In the prodn. of curved hoses for use in the mfr. of vehicle engines, washing machines, etc., whereby a suitably-curved mandrel is inserted into a section of tubing before vulcanisation, centrifugal force is employed to draw the non-vulcanised tube onto the mandrel. The mandrel is pref. provided with a straight, removable nose-piece of smaller diameter than the mandrel which fits onto the end of the mandrel, and which holds the tube ready for drawing-on. The free end of the nose-piece locks into a recess on the edge of a rotatable disc which can be rotated at high speed to slip the tube onto the mandrel. The device eliminates difficult and arduous manual operation. The tube is not gripped by any tools and therefore cannot be damaged. The force is exerted on the full length of the tube and increases with radial distance from the axis of the disc, preventing the formation of rucks and folds.

Patent DE-3100568-A1 (DE)
Inventor: SCHAEFER NIKOLAUS
IPC: C10K1/12
Filed: 1981-01-10
Abstract: The ammonia contained in ammonia- and hydrogen sulfide-containing gas mixtures is selectively removed through a gas washing with an aqueous ammonium sulfite-bisulfite solution, and recovered from the wash solution as a concentrated aqueous solution. For this purpose the coke oven crude gas is washed with an ammonium sulfite-bisulfite solution led in circulation, the surface tension of which amounts to below 80x10-5 N/cm, then the ammonia gas is driven away from the wash solution enriched with ammonia, e.g. by means of steam, and the released ammonia is recovered e.g. as aqueous ammonium solution through condensation of the vapor. The gas mixture is preferably purified or unpurified coke oven crude gas. In order to reduce the surface tension of the wash solution, alkyl sulfate, alkylamine, pyridine base, phenol or homologs thereof are added as surface active substance. The wash circulation is performed at between 15 DEG  and 32 DEG  C.
