Patent DE-3610882-A1 (DE)
Title: Piston pump
Inventor: KORTHAUS ERNST DIPL ING
IPC: F04B53/14
Filed: 1986-04-02
Abstract: The invention relates to a piston pump, double-acting, for conveying liquids, with or without solids, with a multipart piston mounted on the piston rod, with an inner and an outer packing on the piston circumference. A piston of this type is a conveying element in a pump cylinder liner with associated suction and pressure valves. In piston pumps for conveying said media, damage must not be caused to the pump in spite of letting off or drawing off the pump filling in heavy frost. This is achieved by a multipart piston consisting of   a) the piston head (6), arranged rigidly on the piston rod (5), with the scraper ring (7) b) a tension spring (10) lying between the two packings (8, 8), and   c) a sleeve spring (12) arranged centrally in relation to the tension spring (10), with an outer sleeve (11) and an inner sleeve (13) and an elastic element (14, 18) arranged between the two, the inner sleeve (13) being positioned rigidly on the piston rod part (15) and the outer sleeve (11) with the scraper ring (7) being the abutment of the outer packing (8).   <IMAGE>

Title: Self-operated bimetallic temperature-protection circuit breaker
Inventor: ZDARILEK BRANKO
IPC: H01H1/58
Filed: 1986-04-11
Abstract: The self-operated bimetallic temperature-protection circuit breaker, in the case of which electrical erosion is considerably reduced and which is provided for direct installation on the winding of the domestic appliance or motor, switches the current off automatically when the winding temperature exceeds the maximum permissible limit, or at the unacceptable current intensity, and switches on again when these values fall within the specified limits again. Unfavourable electrodynamic repulsion forces which dangerously reduce the contact pressure in cases of severe current surge or short-circuit, and which can even accelerate the contacts, are considerably reduced here since the contact pressure can be increased. The destructive influence of the arc, especially of the switching-off arc, is considerably reduced as a result of the capability for switching off quickly. The basic feature of the invention is that a thermal bimetallic snap-action disc 9, in the form of a rectangular spherical section having a hole in the centre and having an advantageous connection (which is capable of matching) to other components can overcome a greater contact pressure and can additionally shorten the disconnection time.
Patent DE-3613657-A1 (DE)
Title: Endoprosthesis
Inventor: LAABS WALTER A DR MED
IPC: A61F2/46
Filed: 1986-04-23
Abstract: In this endoprosthesis, the stem (3) which can be anchored directly or indirectly on the head part (2) in the manner of a multifilament comprises several individual rods (4) which contact the inner wall of the tubular bone (1) multilocally and at different levels of the bone after the implantation, possibly with minor injury to the inner wall of the bone. The formation of connective tissue at the contact sites, which is a biological functional occurrence and is also found along the rods, biologically leads to elastic/dynamic anchorage of the rods of the stem over an extensive surface area for the inner wall delimiting the inner medullary space and hence to permanent immobilisation of the endoprosthesis with uniformly good distribution of the load over the bone, so that the risk of osteoporosis is also eliminated. Depending on the age and diagnosis of the patient, bone cement can also be used additionally in this endoprosthesis. <IMAGE>

Patent DE-3728660-A1 (DE)
Title: Device for treating a substrate, especially for perforating paper
Inventor: LANGHANS LUTZ DR
IPC: B23K26/082
Filed: 1987-08-27
Abstract: For perforating the paper used in cigarette tips, for example, the web of paper is moved continuously and provided with rows of perforations. The individual small holes are produced by laser beams. To achieve this, a laser beam from a laser light source is directed towards a certain point on the paper for a specific period in each case via a rotating mirror and a lens in time-division operation. It is necessary or at least desirable for the porosity of the perforated paper to be as uniform as possible. When the intensity of the laser beam is constant, however, the porosity fluctuates owing to differences in the thickness of the paper, the amount of colouring agent applied, the water content of the paper etc. To achieve constant porosity, porosity sensors are arranged on the web of paper, the output signals of which are processed by a regulating device, in order to adjust screens situated in the paths of the laser beams in such a way that the intensity of the laser beam ensures uniform porosity. Individual screens are provided for each laser beam and/or for each beam path or for groups of beam paths.
