摘要:
A cat litter box with a pivotable container housed on a frame, the tray floor of which forms a collection tray for cat litter and the like. A cleaning mechanism is arranged standing in the container and reaching to the floor of the tray, with which cleaning mechanism, when the container is pivoted in one direction to clean it, waste matter, particularly feces, can be separated from the cat litter. The container possesses a storage chamber for the separated waste matter which can be moved with the container, which chamber is formed by a bag, the entrance of which chamber is arranged above the cleaning mechanism in the position of use. The tray floor consists in accordance with the invention of a half shell which extends over a span area of less than 250° which with a first part shell section forms the floor of an essentially open collection tray and with the other part shell section forms the rear wall of an interim storage tray for litter, whereby the cleaning mechanism is arranged at the transition segment between the part shell sections, and the storage chamber is arranged in the position of use on the side of the cleaning mechanism facing the interim storage tray and whereby the pivoting of the container from the position of use is restricted to a pivot movement of 120–180° in the one direction.

The invention relates to a substrate (1), especially a glass substrate, coated with at least one dielectric thin-film layer deposited by sputtering, especially magnetically enhanced sputtering and preferably reactive sputtering in the presence of oxygen and/or nitrogen, with exposure to at least one ion beam (3) coming from an ion source (4), characterized in that said dielectric layer exposed to the ion beam is crystallized.

The invention relates to an electric lamp including at least one vessel for producing and emitting visible electromagnetic radiation, a base for securing and making electrical contact with the lamp in a luminaire fitting, and a connecting part which connects the base to one of the remaining parts of the lamp. The connecting part is in the form of a rotationally symmetrical rotary device which allows the remaining parts of the lamp to be rotated with respect to the base, when the base is secured in the fitting, about the axis of the lamp.
摘要:
A light source for an atomizing device, specifically an atom absorption spectrometer comprising one, two, or more lamps, whose ray can be selected by means of at least one two-dimensionally moveable optical selection element, and which can be directed in the direction of atomizing device. Fine-tuning is thereby achieved quickly with little constructive expenditure and with low costs. A very high degree of accuracy is possible from the selector through a rotational and highly adjustable rotation spindle.

A process for producing high strength, high shrinkage nylon 66 filament yarn for industrial fabrics formed as airbag fabrics, the process having the steps of drawing of a nylon 66 LOY filament yarn having a relative viscosity RV of at least 40 by at least three heatable draw roll units, winding the drawn yarn onto a cylindrical yarn support, and at a relaxation ratio of 4 to 10% setting a temperature of a last draw roll unit before winding to between 70.degree. C. and 160.degree. C., and setting a winding tension to less than 0.2 cN/tex.

A rod joint serves as a construction element of a load-bearing structure for supporting a glass wall or glass roof. A plurality of rods are joined together in the joint by a screwed tab connection. The rod joint (10) is distinguished in that the rods (12-22) abut one another, pressing nonpositively against one another, with their end regions each via at least one end face region and that the end regions of the rods, located in the joint are held, screwed together between two cover disks.
摘要:
Multifunctional instrument for ultrasound surgery having an applicator 2 for a dissection of biological tissue, as well as a device for cutting and/or coagulating of the tissue. At the instrument end separate from the ultrasound applicator 2 at least one RF-current applicator 16 or a laser applicator 15 is arranged in a lateral distance from the distal end 3 of the ultrasound applicator 2, whereby an adjustable arrangement is provided. Each applicator 2, 6, 15 is movable in longitudinal direction in a common applicator housing 9. The applicators may be provided in a revolver unit, which is arranged at the instrument and can be rotated around its longitudinal axis.

A method for coagulating tissue during endoscopic surgery by using argon plasma coagulation is described. An endoscope is used having a flexible, hollow tube inserted through one of the working channels of the endoscope. Inside the tube an electrode is arranged stationarily being offset from the exit opening at the distal end of the tube in such a manner that the electrode cannot come into contact with the tissue. Argon or another inert gas is supplied from a source of gas through the tube to the exit opening with such a low flow rate that gas exiting through the exit opening is a non laminar stream which forms an inert gas atmosphere between the distal end of the tube and the region of the tissue to be coagulated, while the exit is maintained at a distance from the tissue to be coagulated, whereby the area of tissue to be coagulated is positioned sidewardly of the extended longitudinal axis of the protruding end portion of the tube.
摘要:
A process of high-speed spinning of a set of thermoplastic monofilaments having a linear density from 1 to 30 dtex, includes spinning to obtain melt-spun thermoplastic monofilaments and airblast cooling of the melt-spun monofilaments. To produce a particularly fine monofilament at high winding speeds, the process also includes guiding the thermoplastic monofilaments directly over a fork-like friction element having axially parallel, spaced apart upper and lower contacting friction surfaces during the airblast cooling, and then spin finishing and winding up the thermoplastic monofilaments. An apparatus for melt-spinning including the friction element is described. The product monofilament produced by the process can have an elongation of 20 to 45%, a strength of 36 to 60 cN/tex; a boil shrinkage of 2 to 15%; an Uster % less than 1 and a uniformly round cross section.
