Abstract: In a connection between a pipe and a molding, a tubular housing, fixed on the molding, engages around the pipe with an inner wall tapering conically toward the free end of the housing. Arranged between the pipe and the housing inner wall is a clamping ring, which braces the pipe with the housing in a wedge-like manner. The clamping ring is held in its wedging functional position by a spring element acting on it in the axial direction. The spring element can be locked in a prestressed state without force acting on the clamping ring. To establish the connection between the pipe and the molding, a locking clip passing through the housing is pulled out of the housing to relax the spring element.

Abstract: Disclosed is a method for controlling a memory address of a digital signal processor in which a memory address is independently managed for each for during parallel processing of a plurality of jobs and no program of the same content as others is stored redundantly. Two bits of a high order A19 and A18 are masked among memory addresses of 20 bits from A0 to A19 which can be accessed for internal and external memories by a digital signal processor. In an address setting and an address computation performed on a program for executing each of jobs of the digital signal processor, only an address space of 18 bits from A0 to A17 can be accessed by an address pointer. The masked two bits of A19 and A18 are accessed by an address area register.

Abstract: A folding tool including a U-shaped handle and a tool element adapted to lie within the handle in its closed position, a tang at one end of the tool element fitted pivotally around a pivot axis between the two prongs of the handle, said pivot axis extending parallel to the plane defined by the tool element, wherein a locking leg extending parallel to the prongs is resiliently suspended on the inner side of the first prong such that a free end of the leg can be pressed towards the first prong against the action of a spring force. The locking leg is provided with locking means adapted to engage with an engagement part of the tang for locking the tool in its 180.degree. opened position, the locking state being disengaged by pushing the free end of the locking leg towards the first prong.

Abstract: A warning and measuring device for personal protection with a rod-shaped casing shape. The shape of the casing allows the device to be suitable 1. for measuring if held in the hand or mounted on a tripod, 2. for warning when carried on the body and 3. for leak detection in hollow conductors. This is made possible through a compact construction and a movable absorber which in an absorber package within a cap can be fitted to the casing while the cap is detachable and can be used as handle on the other end. The device can be economically manufactured and with regard to quality can be considered a high-quality measuring instrument.

Abstract: An improved tanning system involves the use of a film of material which is permeable to ultra-violet light and which is adapted to be laid on part of a human body, for example the torso. The film is covered in certain desired regions with a material which is impermeable to ultra-violet light which regions are surrounded by regions which are only slightly permeable to ultra-violet light. When a person wearing the film is subjected to tanning, the result is improved appearance of the torso, for example, the person may look fitter, slimmer and/or more muscular. The tanning may be achieved by either natural sunlight or by means of a sunbed.

Abstract: The well known slip casting process for the production of ceramic green parts, in which hardening is achieved by water removal with porous molds, is characterized by disadvantages in terms of strength, shrinkage during drying and problems with cracking during drying. The present invention avoids these disadvantages and produces ceramic green parts by changing the surface potential of powder particles in the slip instead of by removing water. Further more the coagulation strength is increased by adding polymers or extremely fine divided colloidal particles.
