Title: Method for producing transverse locking members on slide fasteners
Inventor: KNOLLE HANS-HERMANN
IPC: A44B19/32
Filed: 1989-04-26
Abstract: The invention relates to a method for producing transverse locking members made of textile fabrics with or without coating(s) of plastics or elastomers on one or both sides on slide-fastener end connections. The essence of this invention consists in the fact that the transverse locking member is formed in each case by cutting into the coated or uncoated fabric panel which constitutes the end connection or its reinforcement, by folding the panel strips (3a, b), produced by cutting in on the side of the fabric panel facing the slide-fastener chain, in a direction which is turned in each case through 90@ relative to their original positions, and by attaching the panel strips (3a, b), folded in this manner, parallel to the slide-fastener chain directly next to the tape fold (10) on the side of the two stringer tapes (8a, b) of the slide fastener opposite the slide-fastener chain. <IMAGE>

Patent DE-4004589-A1 (DE)
Inventor: DOBLER KLAUS DIPL ING DR
IPC: G01L3/04
Filed: 1990-02-15
Abstract: A measurement device for determining torque has a torsion pipe (10) in which axial notches (12) are cut. Ridges (13, 14) of different widths are located between the notches (12). Slits (15) are made in the broader ridges (13). At low torques, the torque is therefore transmitted only by the narrow ridges (14). If the torque exceeds the stiffness of the narrow ridges (14), the slits (15) are closed, i.e., the two parts (13a, 13b) of the broad ridge (13) touch each other. As a result, a higher torque can be transmitted by the ridges (13) in a second measurement range or, if the ridges (13) are sufficiently stiff, the ridges can act as an overload protection. Additional overload protection in the form of a recess (35) and a nose (36) may also be provided. The torque sensor is very easy to make and can measure the torque in several measurement ranges and with the help of an overload protection.

Each spring has an arm which fits in a slot (45) in the housing (2).  The spring rate is sufficiently low to allow it to be easily elastically deflected to fit or remove the brake pads. USE - Disc brakes.

Title: Protection of ceramic articles during handling and transport -  by applying viscous mass which hardens to form elastomeric pads
IPC: B65D59/00
Filed: 1990-09-27
Abstract: Articles (1) such as chimney flue sections, made of ceramic, concrete, glass and similar materials are protected from damage while being handled, by an elastomeric covering applied to the regions susceptible to damage. The covering layer (4) is applied in the form of a viscous mass which subsequently hardens to form an elastomeric protective pad. The covering layer is removed by applyinga solvent which dissolves the elastomeric material so that the article is restored to its initial form before being used. The idea is particularly applicable to the handling and transport of ceramic chimney pots. USE/ADVANTAGE - Handling of ceramic articles without risk of damaging them.

Title: Windscreen wiper for motor vehicle - provides compensating drive for high speed displacement of wiper blades
Inventor: YAMAMOTO TOKIHIKO
IPC: B60S1/16
Filed: 1991-03-27
Abstract: The windscreen wiper drive is improved for the wiper arm, which extends the wiper blade to the upright edge of the windscreen, by the addition of a servo drive to alter the effective angle of wipe. This reduces the wipe angle slightly when the wiper is subjected to high wind-speeds, and prevents the blade from being pushed over the edge of the windscreen. A servo motor (9) and an eccentric drive alter the effective drive linkage to the main motor. An eccentric cam (8) about the windscreen wiper stub (w2) is rotated by a sedrvo driven worm drive (10). A plate (18) around the cam is displaced and a linkage to the wiper drive pivot (20) is displaced to effectively alter the wiping area. The servo drive is operated in relation to the vehicle speed. ADVANTAGE - Less damage risk for wiper blade, simple control mechanism.
