Title: Guiding components during sewing - using markings on components to provide signals to sensors which control a transport mechanism
IPC: D05B21/00
Filed: 1990-08-08
Abstract: During sewing operations, partic. of overlapping leather components, the parts are given markings on at least one side which can be picked up by a sensor.

Title: Sensor for monitoring machine tool grease lubrication system - has warning actuating plunger balanced between dispenser pressure and sum of pressures in two distribution lines
Inventor: WENGENROTH KURT
IPC: B23Q11/00
Filed: 1991-02-05
Abstract: Grease in a pair of lubrication lines (2) distributing grease to various points of a machine tool from a central dispenser passes through parallel bores (4) in the sensor block. The two bores are connected by a cross-bore (5) which has a larger dia. (6) opening onto one side of the block. A stepped plunger (7) slides in the cross-bore with a small axial movement limited inwards by the collar (12) and outwards by an electrical switch arrangement.

Abstract: (A) An impression is taken, during denture prodn., of a toothed human jaw together with the mucous membranes, using a moulding tool (1) having a mouth front edge, a tongue-side or palatal edge and a channel-shaped casing. The novelty is that a highly viscous hardenable impression material (11) is applied around the periphery of the tool (1) at least in the region of the front edge and the tongue-side or palatal edge, the tool (1) then being pressed onto the mobile mucous membrane and, after hardening of the impression material, removed together with the hardened material from the jaw for prodn. of a fully individualised moulding tool. This tool is then filled with a low viscosity hardenable impression material, pressed onto the jaw, left in place until the impression material hardens to a final hardness of max. 30 Shore A and then removed together with the impression material from the jaw. (B) Also claimed are the following materials for use in the process: (i) a high viscosity impression material selected from polyvinyl polysiloxanes, having a viscosity of more than 200 Pa.sec. in the unhardened state and a hardness of 55-75 Shore A in the hardened state; and (ii) a low viscosity impresssion material selected from polyvinyl polysiloxanes, having a viscosity of less than 160 Pa.sec. in the unhardened state and a hardness of less than 30 (pref. less than 25, esp. less than 20) Shore A in the hardened state.
