Title: Apparatus for grasping bar-shaped articles
IPC: B65G47/90
Filed: 1988-11-02
Abstract: An apparatus for grasping bar-shaped articles which are to be conveyed on a specified conveying path is formed as tongs having at least one leg. The leg is arranged so as to be swivellable about a swivelling joint. At its end facing away from the swivelling joint, the leg is provided with a receptacle which can be swivelled in the direction of the article and which, in its swivelled state, clasps the article and, in its swivelled-away state, is uncoupled from the article. Two legs which are controlled in opposite directions are mounted so as to be swivellable in the direction of the article. The two legs are mounted so as to be swivellable in a common swivelling plane. Each leg is articulated, in each case via a swivelling joint, to a mounting with respect to which a swivel control device is movably mounted. The swivel control device is articulated, via in each case one actuating lever, to each of the two legs. The actuating lever is swivellably mounted both in the swivel control device and on the leg.

Title: Heating element control system for oxygen concentration sensors
Inventor: NINOMIYA MASAKAZU
IPC: G01N27/417
Filed: 1988-12-15
Abstract: A heating element control system for an oxygen concentration sensor is described in which the basic electric power to be fed to a heating element contained in the oxygen concentration sensor is determined from the speed of rotation and from the intake pressure of an internal combustion engine. The heating element resistance value at a stable operating condition of the internal combustion engine, at which the heating element temperature is to be controlled to essentially 1100@C, is stored as an empirical value. The differences between this empirical value and the heating element resistance values at different operating conditions are used for the computation of a plurality of correction factors for correcting the basic electric power.

Title: Pipe coupling, in particular coupling for the exhaust pipes of vehicles
Inventor: PUESCHEL ECKARD
IPC: F01N13/18
Filed: 1989-01-19
Abstract: A bayonet pipe coupling for exhaust pipes of vehicles is described. The claw segments of the bayonet closure element here comprise shoulder segments of the other pipe. The faces of the claw segments or shoulder segments which face one another are of wedge shaped design so that in the course of the rotational movement the two pipes are clamped to one another. For this purpose, an elastic sealing element is provided. A rising wedge angle of the wedge faces is adjacent to a wedge face which has a decreasing wedge angle. Therefore, the pipe coupling can only be released if the clamping force is increased so that automatic release is excluded.

Patent DE-3910873-A1 (DE)
Inventor: LANFER HERMANN DR
IPC: G01D5/34
Filed: 1989-04-04
Abstract: A position indicating apparatus for crane ways and overhead conveyors and the like includes a code carrier (11), which carries multi-value code marks (18) in one track along its length. The code marks (18) are combined into blocks (17), with which a block identification (22) is associated. Cooperating with the code carrier (11) and the block identification (22) are a code reader (12) and an auxiliary reader (24), respectively. Along the travel path, the code carrier (11) and the code reader (12) are disposed counter to one another. To enable increasing the length of the addressable travel paths without losing positional accuracy, or without having to increase the number of code marks (18) in one code word (35), a block identification (22) is associated with the blocks (17). From the block identification (22), an auxiliary reader (24) can recognize whether the code reader (12) is reading only code marks (18) from one block (17). In this way, the travel path can be divided into important zones (27), in which the accurate position of the vehicle must be known, and to which blocks (17) must therefore be assigned, and unimportant zones (28), which are merely gaps (19) between blocks that connect the important zones (27) to one another.

IPC: A47L23/02
Filed: 1989-05-08
Abstract: The shoe cleaning and polishing device has brushes (4,5) fixed by holders on a base plate whereby the bristles directed to the sides are attached in front of those directed downwards. Between the bristles  which process the longitudinally aligned parts of the upper, and the holders there are two or more compression springs (6a,6b,7a,7b) set at regular intervals so that the brushes are restricted in their movement to sides other than the longitudinal direction of the compression springs through built-in slide tracks. Beneath the rear end of the downwardly aligned brushes there is a transverse brush which grinds on the base plate and dirt grid and is likewise mounted in compression springs. USE/ADVANTAGE - An effective finishing of the entire upper whatever its dimensions is now ensured.

Title: Measuring physical value by fibre=optic sensor - using two sensor leads alternatively used as send and receive fibres and useful and reference light beams
Inventor: WIESMEIER ALBERT DIPL PHYS DR
IPC: G01D5/26
Filed: 1990-04-25
Abstract: An optical fibre sensor (10) is used for working with useful (13) and reference (12) light beams. Light is bidirectional applied to two fibre-optic sensor leads (6.1, 6.2) operated as send and receive fibres. Each light beam is led to a different path according to its direction of dispersion through a light junction. The latter pref. consists of two optical elements allowing the light to propagate in one direction but interrupting it in the other direction to function as light valves. The latter are arranged in opposed directions for sensor and reference branches.  The light valves can be realised as an optical isolators using the Faraday effect. ADVANTAGE - Does not depend upon reflection of a definite part of the light in the send fibre. Thus no parasitic reflections can occur to affect the measuring process.
