Patent DE-2335780-A1 (DE)
Title: Jointed sections conveying tube for hot ground solids - with hinge pin connecting differently tapered adjacent ends of two sections
Inventor: HUERTER WILFRIED DIPL-ING
IPC: B65G53/54
Filed: 1973-07-13
Abstract: The front end of each tube, is tapered inwardly and the rear end of the next tube, is tapered outwardly outward. A hinge pin connects the two tubes where the inward cone enters a certain distance into the outward cone and the whole joint is enclosed in a flexible or bellows section. A gap is allowed between the two cones through which some pressurised carrier medium such as air or steam can be injected to convey the product in the pipe. The distribution for this to each joint can be constructed as the conveying tube and both can be supported in a chain type frame the hinge pin of the chain coinciding with and coaxial with the hinge pin of the tube.

Title: Loom electronic programme control system - having printed logic circuits to determine weft insertion and warp control functions
Inventor: FERNANDEZ JOSE LOPEZ
IPC: D03D51/00
Filed: 1973-07-31
Abstract: The programme control for a loom is exercised by electronic units in three gps. (1) to determine current supply and weft propulsion; (2) logic control through printed circuits; and (3) control of the loom mechanism. The current supply control also includes the time control units to brake the shuttles or lances, temp. control and the control on feed of the warps. The logic control determines the shuttle or lance propulsion using triacs and thyristors together with four thyristors and two block correctors for rapid braking, and two impulse transformers for the thyristor inputs on forward and reverse shuttle control. The system gives a precise and accurate control of the loom function, esp. weft insertion and weft tension, using a self-braking linear motor for weft carrier propulsion.

Title: Achieving burnt out effects on textiles - by dissolving out fabric substrates, from embroidered textiles
Inventor: SEBB WERNER
IPC: D06C23/02
Filed: 1975-07-07
Abstract: Effects are achieved by dissolving out fibre pt. to be removed from fibre union. Process takes place by dissolving fabric substrate in a suitable solvent which does not dissolve embroidered on textile pt. Process is used for prodn. of lace, e.g. (a) of polyester lace from acetate rayon embroidered with polyester fibres or (b) or cellulose fibre lace from acetate- or triacetate fabrics embroidered with cotton or linen. Process is quick and requires no dry heat and acids. Both dissolved fibre material and solvent can be recovered. In pref. processes, substrate is of acetate or triacetate rayon. Solvent is acetone, CHCl3, or CH2Cl2. Burning out takes place from 15 degrees C to b.pt. of solvent, esp. at 40-50 degrees C. In example, 200 g polyester-embroidered cellulose acetate fabric were turned 3 min. in 8 1 acetone at 50 degrees C. Acetate fibres were dissolved.
