Title: Handling device for storage system - has workpiece storage in form of palette shelves with horizontal slide-in slat for palettes
Inventor: FUEGLEIN EGON DIPL ING
IPC: B23Q7/10
Filed: 1975-08-09
Abstract: The processing system consists of a machine tool, a handling gear for charging the machine tool with workpieces, and a workpiece storage device. The workpiece storage device is palette receiving shelves (3) with slide-in slats (6) for the palettes (5). The vertical distance between two adjacent slats (6) is equal to the height of the smallest possible workpiece (4, 8). For the fixing and positioning of the workpieces (4, 8) the palette surface has a contact adhesive coating.

Inventor: WINTER III GEORGE ROBERT
IPC: C07C5/32
Filed: 1975-09-19
Abstract: Dehydrogenation of 5-18C n-paraffins using catalyst comprising 0.01-2 wt. % platinum and 0.01-5 wt. % alkali, pref. Li or K, or alkaline earth components on porous alumina support; opt. 0.1-5% wt. germanium component may also be included. Process is improved by (a) injecting 5-25 ppm. wt water (based on fresh hydrocarbon), together with the hydrocarbon and a gaseous recycle stream, into the reaction zone at the start of the process and (b) increasing rate of water addn. up to 25-125 ppm. wt. after at least 40% of feed which may be processed before catalyst replacement is required has passed through reaction zone. Maintaining presence of defined amts. of water in reactant streams increases catalyst life and conversion rates at specific temps. during catalyst life.

Title: Procedure for water injection in coal seams - has water quantity controlled by degree of reduction in friability of rock
Inventor: EHRHARDT WILHELM DR ING
IPC: E21F5/18
Filed: 1975-10-03
Abstract: The procedure is for injecting water into strata especially coal seams in mines using boreholes driven down to the seams. In the boreholes are then inserted probes connected to a supply of pressurised water. The quantity of water to be injected is so controlled as to suit the degree of reduction in tectonics forces. The quantity of water is reduced before reaching transition zones with areas of different reduction grade of tectonics forces with different stresses and is sharply reduced against the normal quantity in the transition regions. Chemicals may be added to the water which held to bind together the dust.

Title: Sacks produced automatically on raschel machines - separate lengths of double fabric being triple-seamed, and linked by control threads
Inventor: ARNOLD ROLF
IPC: D04B35/34
Filed: 1976-01-20
Abstract: In a sack without the classical side seams; the wales at the edges are laid in by double acting guide bars and secured to each other, whilst at the sack bottom a number of double rows of stitches are knitted. A reciprocating rod entering the fabric closed on three sides, takes off the sacks from the machine. Sepn. takes place in a zone of less density. Sacks with their warp knitted wales running lengthways, are produced with at least two tubes knitted side by side, and linked by a control thread, by means of which the mechanism for separating the sacks is actuated, and prodn. up to and including the stacking of the goods, is automatic. The control threads may be used to form the side seams joining together the two lengths of fabric forming the front and back of the sack. They then link the neighbouring tubes of fabric across the gaps in the zone of the bottom seam of each sack, formed by rechts/rechts rows of stitches. The continuously produced sacks are separated from the running length in one operation and transferred completely finished to the stack at very high speed.

Title: Washing machine employing a vacuum-operated diaphragm - to force liquid through the clothes and then squeeze them damp-dry
Inventor: ALDER EMANUEL
IPC: D06F15/02
Filed: 1976-11-04
Abstract: The wash tub is closed airtight by a flexible sheet. From the bottom of the tub, a pipe leads through a storage tank to a vacuum pump. The vacuum draws the soapy water through the clothes into he storage tank, then further suction pulls the flexible sheet down on to the clothes to squeeze them dry. The vacuum is then released, the soapy water returns to the tub through a filter, which holds back the dirt particles, and the procedure is repeated until the clothes are clean. Finally a tap is turned, so that when the vacuum is released the soapy water cannot return to the tub, and the damp-dry clothes are removed. Method is considered to be kinder to the clothes than, e.g. spinning them dry.

Title: Self checking neck frame for pigs - has U=shaped main frame with common connecting strap for both shanks
IPC: A01K1/062
Filed: 1977-06-15
Abstract: Self catching neck frame for pigs where a U-shaped main frame can be suspended in a pig stall and partly encloses a head opening which carries on into a neck opening through which the pig can stick its head. A closing lever has a top closing-and a bottom operating arm and can be swivelled about an axis normal to the frame plane from an open position into a closed position and back. In these positions, the closing arm releases the head opening or so constricts it that the pig cannot remove its head. On the opening position of the closing lever, the operating arm constricts the neck opening so that it moves from the pig's neck and the closing lever is swivelled into its closing position, in which it can be locked by a locking device. The cross-piece of the U-shaped main frame is the top boundary and the two shanks are side boundaries of the head opening. At their free ends, they have connectors for a flexible chain.

Title: Sewing machine fabric holder drive - has an epicyclic gearing giving intermittent action allowing movement while the needle is still
Inventor: HAGER WALTER
IPC: D05B21/00
Filed: 1977-07-23
Abstract: The intermittent drive mechanism for the fabric holder of a sewing machine has two inputs for the fabric holder, forming its epicyclic gearing. One input is connected to the drive, while the other input is connected to an oscillating drive. This takes up the reaction momentum from the drive linkage actuated by the drive unit through the sun wheel dependent on the drive of the sewing machine. As the needle penetrates the fabric, there is a subtraction of the drive movement, which is at its maximum at the lower dead point of the needle. The mechanism allows the fabric holder to be moved from the prepn. station to the sewing station while the needle is stationary.
