Patent DE-4140690-A1 (DE)
Inventor: REBHAN DIETER
IPC: C03B7/10
Filed: 1991-12-10
Abstract: In the production of glass beads from a molten glass material with the aid of shear blades, it is proposed to expose the shear blades to a cold inert gas and subsequently cut glass beads from the glass material emerging from a feeder by means of the cold shear blades. This gaseous cooling circumvents, in particular, the disadvantage of the harmful frost effect which occurs in the case of liquid coolants and greatly reduces heat exhange.

Title: Carpeting waste recycling - involves washing ground fine fibre waste to be converted into bonded nonwoven felting
Inventor: SCHATZ MANFRED
IPC: D21H15/00
Filed: 1991-12-23
Abstract: The waste material with a textile content, such as waste carpetings or vehicle interior claddings and the like, is ground and reduced to fine fibres. The fibres are cleaned in a bath and then compressed into a felting, pref. by an angled sieve mesh appts. The felting non-woven is finally bonded. The fine fibres are washed in water, pref. with an added detergent which, after use, is cleaned and returned to the washing bath. Before compression and bonding into a non-woven felting, a bonding agent is added to the mixture as ground fine fibre waste and water. The material is finally bonded by immersion in latex, and the like, to be dried and rolled. ADVANTAGE - The technique recycles high bulk and large volume textile waste materials, cost effectively, without damage to the environment, to give a floor covering or acoustic insulating material

Title: Button clamps - are part of parallel motions to hold and position buttons of various dia. for stitching
Inventor: VOIGTLAENDER LUTZ
IPC: D05B3/14
Filed: 1991-12-27
Abstract: The button clamp, for a button sewing machine, has two laying points at each holding pad (2, 3) of the clamp units (5,6) which, together, form a right-angled laying point with each other. The theoretical line between the laying points at each holding pad is at right angles to its opening and closing direction. The clamp sections are each part of a parallel motion (7, 8) so that their working movements coincide with an opening and closing direction. The parallel motion (7,8) for each clamping unit (5,6) is pref. a flat four-link parallel crank drive with a free end to form the clamp (5,6). The linkage points, (16, 17) of the free links are at the top apex point of the cranks (12-15) when the clamps are at a centre position in relation to each other. An operating link (20) moves the mechanism to bring the clamps and holding pads (2,3) towards or away from each other. The structure of the linkages (12-15) in the parallel motion is flat, so that they can move within each other. The two motions have a common linkage point (9, 10) for each at the frame. The operating link (20) is a twin-armed lever (21), pivoting on the frame, to move linkages (23, 24) at each end connected to the cranks (12-15) of each parallel motion. USE/ADVANTAGE - The appts. is to hold and clamp a button in a centered position, for the sewing machine needle to stitch it to the fabric. The system gives an automatic holding and positioning action to the button, of various dias. The buttons can be fed automatically or manually.

Abstract: The assembly for continuous mfg. of roofing felt, where the carrier is coated with bitumen and sand or gravel, has measurement systems (7,25) for the carrier material (2), connected to a control, at the sanding station (13) and cutter (17), to stop sanding at intervals. A measurement unit (7) registers the length of the incoming raw carrier (2), and after a given length has passed, stops the action of the sanding station (13). A detector, in front of the cutter, registers an unsanded section of the material to activate the cutter. The sanding station (13) has a silo (13) and slide (14) with a system either to block the silo outflow (13) or deflect the slide (14) when the material is not to be sanded. A thin polyethylene covering band is fed as strips to the coated carrier. USE/ADVANTAGE - The assembly is for the continuous prodn. of prepd. and rolled roof felting material, using a cardboard carrier. The finished prod. gives improved bonding area with adjacent roof feltings.
Patent DE-4202827-A1 (DE)
Inventor: LISSACK WILFRIED DIPL ING
IPC: F27D17/00
Filed: 1992-01-31
Abstract: A procedure for operating industrial furnaces is provided, whose waste gases are burned in the waste gas line. According to the invention, the temperature of the waste gas is continuously measured and, when a preset value of the measured waste gas temperature is exceeded, the oxygen content of the atmosphere of the industrial furnace is increased. This has the result that the carbon monoxide released in the furnace and the hydrogen are burned under control already in the furnace and not only in the waste gas line. In this way, energy for heating the industrial furnace can be saved and downstream filter installations are thermally protected.
