Patent DE-3302948-A1 (DE)
Title: Contactless optical distance measurement
Inventor: BRUNK WOLFGANG
IPC: G01C3/10
Filed: 1983-01-29
Abstract: By applying the Scheimpflug principle to optical distance measurement by triangulation, it is possible to use image sensors that are dependent on sharp focus without the limitations on the maximum change in distance that is to be reliably detected which are present because of the defective depth of focus that otherwise occurs along the measurement axis. As a result, it is possible to use cost-effective digital image sensors which are simple to interpret and have a high geometrical accuracy and stability in conjunction with a high resolution.

Title: Tool cassette for machine tools
Inventor: RIEDEL FRANZ
IPC: B23B29/04
Filed: 1983-03-23
Abstract: A cassette (1) is shown which is adjustable in its length and has a cutting blade (4) which is supported against the tool carrier (3) via a wedge-shaped intermediate piece (2). The intermediate piece (2) extends over the entire width of the cassette and when displaced in its longitudinal direction brings about a parallel displacement of the cassette (1) in a radial direction to the bar (5). The wedge-shaped intermediate piece (2) is fastened to the cassette body by screws (7). The cassette can thus be set to the desired length dimension (22) in a setting device outside the machine and during operation of the machine with other cassettes. The cassette is set by the screws (16, 17), which adjust the intermediate piece (2) transversely to the longitudinal extent of the cassette. The cassette is mounted in the setting device in a flexible manner in the direction of its longitudinal extent. <IMAGE>

Title: Device for delivering a sequence of similarly oriented articles
Inventor: HILGENBOECKER HORST DIPL ING
IPC: B65G47/14
Filed: 1983-03-21
Abstract: The device for delivering a sequence of similarly oriented articles from a number of unordered articles essentially contains a conveyor device and a rotatable ring wheel, the conveyor device being arranged inside the ring wheel. The conveyor device designed preferably as a continuous conveyor feeds the articles to the ring wheel in random orientation. The articles are then ordered on the ring wheel in an ordering region downstream of the feeding region of the articles on the ring wheel. All articles lying on the ring wheel with an impermissible orientation are rejected by the ring wheel in the ordering region, returned to the conveyor device and once again fed to the ring wheel together with the next batch of unordered articles fed by the conveyor device. As the articles do not hinder one another during the ordering process, the device according to the invention avoids any danger of piling up during the ordering process. Rapid and reliable processing of articles which cannot be ordered at all or can only be ordered with great difficulty within the unordered heap or on the conveyor device is possible in addition. Relatively large and heavy articles, as well as delicate articles, can also be ordered without problems.

Title: Continuous method for the production of discrete tube lengths of reduced diameter
Inventor: EDDENS FLETCHER CALVIN
IPC: B23D31/00
Filed: 1984-02-18
Abstract: A continuous method for the production of discrete tube lengths of reduced cross-section from a long tube of relatively large cross-section is disclosed. The tube to be reduced in cross-section is weakened at predetermined points along its length by notching the tube wall or in some other similar manner and is fed to the processing station, where it is deformed by compression. The cross-section and wall thickness of the tube are reduced and give rise to a corresponding lengthening of the tube. The deformation due to the compressive force applied separates the tube into lengths at the weakened points. The tube emerges from the processing station in the form of discrete tube lengths of reduced diameter and predetermined length and these can be removed at that location as they arrive. <IMAGE>

Title: Method for cold production with the aid of a sorption liquid
Inventor: SEGELETZ PETER DIPL ING
IPC: F25B15/02
Filed: 1984-03-08
Abstract: The invention relates to an improvement of methods for cold production by means of an absorption liquid, the boiling point of which is moderately high in relation to the refrigerant and which during desorption requires a rectification of the refrigerant. The aim of the invention is to achieve an improvement to the effect that the reduction of the heat expenditure during the release of the refrigerant in the desorber is achieved by easing the purity requirements of the head product and the usability of pairs of working substances with a low boiling-point separation is made possible. According to the invention, this is achieved in that the refrigerant removed from the circuit is introduced into the high-pressure evaporator and used for cold production. Subsequently, the refrigerant is resupplied to the circulation. The invention can be used in absorption cold installations with pairs of working substances with a boiling-point separation which is low to moderatly great, preferably for the pairs of working substances ammonia/water and monomethylamine/water. <IMAGE>
