Patent DE-3809867-C1 (DE)
Title: Testing apparatus for material properties
IPC: B01L3/00
Filed: 1988-03-24
Granted: 1988-10-13
Abstract: Testing apparatus for material properties of essentially cup-like shape are known, into which are introduced various reagents and also the material to be tested, it being possible subsequently to make a statement about certain material properties by means of, for example, a colour change. Either the apparatus in such devices is very complicated or the reagents have to be handled in the open, which can present a hazard to the user depending on the agents used. The new testing device is to ensure safe handling and safe use of the reagents employed with little complicated apparatus. A testing device for material properties is proposed, which comprises few individual parts and in which first the reagents and, after charging the material to be tested, this material too are enclosed without being able to escape from the testing device. Reagents and material to be tested are here taken up by chambers which are configured so as to be rotatable about a common axis of rotation and during rotation pass an orifice one after the other, which orifice makes possible the discharge of the respective chamber into a common reaction chamber.

Granted: 1990-07-26
Abstract: The invention provides an apparatus for fixing a workpiece to be machined by a machine tool to the worktable of the machine tool in an exactly determined positional relationship with reference to a reference point located on the worktable of the machine tool. The apparatus of the invention comprises a workpiece receiving means adapted to removably receive the workpiece to be machined, and first positioning means comprising a first group of positioning apertures provided in the workpiece receiving means, and a first group of positioning studs provided on the worktable of the machining tool, said first group of positioning apertures and said first group of positioning studs cooperating to determine the position of the workpiece receiving means in X- and Y-direction. Further, there are provided second positioning means comprising a second group of positioning apertures and a second group of positioning studs, said second groups of positioning apertures and positioning studs being located distantly from said first groups of positioning apertures and positioning studs and cooperating with each other. The cooperating second groups of positioning apertures and positioning studs determine the position of the workpiece receiving means either only in X-direction or only in Y-direction, but not simultaneously in both directions.

Title: Laser range finder with fibre=optic propagation time component - couples two glass fibres to photodiode, one being in closed ring form or bounded at both sides by reflectors
IPC: G01S17/14
Filed: 1991-03-26
Granted: 1992-06-11
Abstract: The laser distance measuring equipment (DME) operates according to the propagation time measurement principle and mainly consists of a transmitter source emitting a short duration pulse, a receiver sensing part of the radiation reflected from a target and a fibre-optics reference path. The radiation component propagated at least once over the reference path is, indirectly or directly, decoupled in advance out of the transmission cone by means of the fibre-optics reference path provided by at least two glass-fibres (5,6) functionally coupled together via an optical coupling element (7). The latter is pref. a symmetrical directional coupler, which emits light in one direction only, and couples 2% of the radiation which arrives (at c) and emerges (at b) for example. If the distance or time resolution is less than the laser pulse-length, two directional couplers are needed. ADVANTAGE - Accurate measurement of measurement pulse transit time without extra cost.
Patent DE-4140512-C1 (DE)
IPC: F16B13/04
Filed: 1991-12-09
Granted: 1993-04-08
Abstract: An anchoring plug made from a hard-elastic plastic material having a closed shank part 1 and two mutually opposite spreading fingers 2 and 3. A screw hole 10, extends through the shank part 1 down into a central space 12 between the spreading fingers for receipt of a screw 18. To be able to drive the plug directly into gypsum board without having to first drill a hole, one spreading finger 2 is longer than the other spreading finger and has a hook-shaped tip 4 forming a recess 5 at its free end. Initially the end of the shorter spreading finger 3 nests in this recess to provide a pointed end to the plug, but springs free of the recess when a screw is screwed into the plug.

A flowrate value of the liquid from the feeding pipeline 1 and the flowrate of liquid to be emitted from the tank are being maintained by changing a fixed position of the level pickup in the tank. A flowrate through the openings, being maximally opened in the feeding pipeline, is more or equal to the predetermined flowrate of the liquid to be emitted from the tank. EFFECT: enlarged functional possibilities of the method and the apparatus due to automatic maintaining of predetermined flowrate values of liquid to be fed and to be emitted from the tank. 4 cl, 4 dwg
