Title: Anti-theft device for parked skis and ski sticks
Inventor: HEIM GEORG DR
IPC: A63C11/00
Filed: 1984-02-07
Abstract: Anti-theft device for skis and ski sticks. To reduce the recurring thefts of skis and ski sticks parked during a break in front of huts, mountain railway stations, etc., there is produced a locking device in the form of a clip with two shackles (similar to a safety pin), in which the two shackles, but at least one, can be swung open and shut movably at a centre of rotation. The shackles are made of light metal or very durable plastic. A lock (cylinder lock or number lock) is worked in or cast in at the end of one shackle. The other moveable shackle, since it is bent, can be inserted into this lock and the lock fixed. The two skis placed with the tread surfaces together, and in the extended version also the ski sticks, are surrounded at the narrowest point underneath the ski tips by the two shackles of the clip. Since anyone carrying away skis (with sticks) locked in this way attracts attention immediately and, if appropriate, can be checked, thieves usually will not single out skis locked in this way for theft.

Title: Plastics profile bar and process and crosshead die for the production thereof
Inventor: HAFFER DIETER DIPL ING DR
IPC: B29C48/09
Filed: 1984-10-19
Abstract: A plastics profile bar having a foam core, a skin covering its outer and/or inner surface and at least one reinforcing strand embedded in the region of said skin so as to transmit shear forces has a skin formed separately from the foam core. The reinforcing strand is embedded in the foam core adjacent to this skin. Production is carried out preferably by co-extrusion of the foam core, of the outer and/or inner skin separate from said foam core and of the strand or strands, specifically preferably in a crosshead die in which the extruder die for the foam core is arranged such that foaming takes place towards the skin and presses the reinforcing strand or strands against said skin. Between the rectangular or annular die corresponding to the contour of the skin and intended for the extrusion of said skin, and the slit die, rectangular die or annular die for the foam core, there is thus a significant spacing, in which guide channels are formed through which the strands pass. The strands can lie against an inner and/or outer skin.

Title: Method for saving external heat and cooling water in two-stage absorption processes
Inventor: SEGELETZ PETER DIPL ING
IPC: F25B15/12
Filed: 1985-03-04
Abstract: The invention relates to a method for saving external heat and cooling water in two-stage absorption refrigeration processes with a low-pressure and a high-pressure circuit, in which the working medium vapours of the low-pressure desorber are absorbed in a resorber. In this case, it is the aim of the invention to reduce the external-heat and cooling-water requirement of the entire installation by regenerative uncoupling of heat at the hot end of the resorber, this uncoupled heat being intended to cover for reaching the boiling states of the rich solutions before entering the respective desorber.   According to the invention, this is achieved by the resorber consisting at its hot end of one or two separate preresorbers, in which the rich solution absorbs process-internal heat and downstream of which resorber(s) at the cold end a main resorber cooled with cooling water is connected. The invention can be used in all thermodynamic absorption processes with two solution circuits, in which the desorbers are executed as pipe columns and have great degassing widths. <IMAGE>

Title: Intonation slide and lengthening push-in slides for brass instruments
Inventor: NOLTE ULRICH
IPC: G10D9/00
Filed: 1985-05-29
Abstract: The invention relates to a U-shaped smooth-running intonation slide for brass instruments, especially for Wagner tubas, bass tubas, natural horns and natural trumpets. The said slide is held in the rest position by two springs which act against one another and immediately returns to this position from any other position. It is operated by means of a handle which is easy to use for the operator. This movement of the handle is transmitted to the intonation slide by a simple mechanism. In this way, unclear notes can be counteracted, especially in tubas. The shortcoming of these instruments, which is that corrections cannot be made with the hand in the bell, can thus be counteracted. Furthermore, it is possible to produce clear notes from naturally unclear ones in natural instruments, while at the same time preserving the character of the natural instruments to a substantial extent. Furthermore, it is possible to equip valved instruments with multiply wound push-in slides instead of conventional rotary or pump valves, which push-in slides are in each case actuated by a key analogously to conventional valve keys. As each push-in slide has a different number of windings, each time the different keys are actuated, the instrument's pitch is modified to a different extent, even though the key path is the same.
