Title: Multiple contact microswitch for flat cable - has contact blades penetrating cable insulation and sliding buttons on top of housing
Inventor: RAMISCH HANS
IPC: H01H1/58
Filed: 1980-06-04
Abstract: The connection system between a piece of apparatus and a printed circuit connector or between two printed circuit connectors, uses multi-cored flat cables, with conductors spaced 2.54 mm apart. To enable connections to be made between these conductors, microswitches are used, each containing pronged connecting blades which penetrate the insulation of the cable to make contact with their conductor wires. These blades are spaced to match the spacing of the conductors, and have extensions at their tops which are bridged by sliders projecting through the tops of the switches. The conductive extensions at the top can be arranged in alternative manners to give different switching operations between the circuits connected by the cable. A double switching system may be used, with two sets of sliders moved in opposite directions. The switch has a base into which fits a middle part under a cover containing an insulating block, forming guides for the contact blades. The parts can be separated for interchanging the contacts.

Title: Method of painlessly extracting nails affected by onychosis, and of simultaneously producing nail prostheses
Inventor: SCHLICKSUPP CHRISTIAN
IPC: A61B17/54
Filed: 1981-02-21
Abstract: The previous method of nail extraction is associated with considerable pain and leads to, often prolonged, difficulty in working or even to inability of the patient to work. In addition, healing and the growth of the re-growing nail are unfavourably affected by the constant pressure of the shoe, and this in turn has a cosmetic disadvantage. In order to avoid all this the diseased nail is carefully loosened using appropriate instruments and callosity- softening means and is carefully removed, the exposed nail bed is disinfected, prepared and provided with a new nail prosthesis which protects the nail bed, cannot be detached therefrom and grows along with the new nail, so that the patient can go back home or to work without discomfort and without pain after the treatment. The prosthesis is advanced by the re-growing nail and can be treated like a natural nail.

IPC: F16F9/36
Filed: 1981-04-11
Abstract: Hydropneumatic two-tube vibration dampers have an operating space, which is filled with damping fluid and holds the operating piston and the piston rod (6), and a compensating space, which contains partially damping fluid and partially compressed gas. Both spaces are connected to one another at the bottom via a valve and at the top via a closure unit which contains the piston rod seal (8) and a porous body (12, 12a, 12b, 12c), which is located beneath said piston rod seal and acts as a venting device, and a venting channel (15) leading to the upper end of the compensating space. The porous body (12, 12a, 12b, 12c) is permeable to gas and fluid but has an adequate flow resistance. In order to provide a flow path for the leakage fluid, possibly containing gas bubbles, and to prevent the ingress of gas into the space (10) surrounding the piston rods seal (8), the porous body (12, 12a, 12b, 12c) has an angle-shaped cross-section, shielding the piston rod seal (8), and is provided on the surfaces facing the piston rod guide (4) with edge zones (13, 14) of reduced flow resistance. <IMAGE>

Title: Aseptic screwed pipe union
Inventor: ZAHRER STEFAN
IPC: F16L19/03
Filed: 1981-11-02
Abstract: The invention relates to an aseptic screwed pipe union which consists essentially of two connecting pieces which can be clamped against one another, a seal, preferably a O-ring, being located between the connecting pieces.
