Patent DE-2513101-A1 (DE)
Title: Sieve type contact plate - made up of interlocking plastic modular elements
Inventor: KOLLER JOHANN
IPC: B07B1/46
Filed: 1975-03-25
Abstract: In a sieve-type contact plate made up of modular plastic elements which have sieve opening and which are held together to form the plate, each element has projecting teeth on two opposite sides. The teeth are drilled out and the teeth of adjoining elements interlock so that the drillings in the teeth of both elements are aligned. A number of elements are held together by anchoring rods which pass through these drillings. The elements are cheap and simple to produce. The proportion of each element acting as an interlocking section is small, leaving a large proportion of the surface area available for sieve openings. Plates made up of the elements are rugged enough to withstand the rough conditions experienced during operation in columns.

Title: Self-locking roller blind catch - has ventilation slits and lever engaging locking bolt by its own weight
Inventor: MICHEL MANFRED
IPC: E06B9/86
Filed: 1975-05-13
Abstract: The lever engages the locking-bolt by its own weight. A cord fixed to the top piece of roller-blind releases the locking-bolt by means of a lever. On the left and right hand sides of the bottom piece of roller blind is a tubular collar with a locking-bolt moved by a lever. A cord on the left and right hand sides of the top piece of roller blind is joined to the lever. The lever pushes the locking bolt into the grooves of the roller-blind guide-rail or underneath a stop-piece. The ventilation slits open from top to bottom. When the last three ventilation slits are opened, the cord pivots the lever on the fuldrum, and the lever hooked into the locking-bolt, is pulled out of its locked position.

Title: Tractive force measuring test bed - has bearing-mounted adjustable plates with overload protection
Inventor: BROSA ERICH
IPC: G01L5/00
Filed: 1975-05-15
Abstract: The motive force test bed comprises two platforms (18)(19) which can be joined together by the test link(20). One platform acts as a fixed support and can be bolted to a test bench or machine (22). The second plate (18) serves as a housing for a bearing block (23). Forces operating on the bearing parallel to the face and perpendicular to the link (20) produce a movement proportional to the force between the two platforms and this can be measured using a suitable strain gauge or similar transducer. An overload protection device can be fitted in the base of the bearing block to prevent fracture of the working parts. An inductively-coupled transducer element may also be employed to measure the forces.

Title: Connecting terminal for aluminium electrical conductor - has riveted joint preventing penetration of oxygen and protects against corrosion
Inventor: HASELHORST HANS DIPL ING
IPC: H01R4/62
Filed: 1975-09-18
Abstract: A connecting terminal is used for an aluminium electrical conductor. It consists of an aluminium pin (2) which is clamped into the holder by means of a joggled rivet (3) using high pressure. The object of the riveted joint is to prevent penetration of oxygen or moisture to the actual contact body and will also eliminate the effect of thermal expansion. The transition at the riveted joint is also protected against corrosion by an additional insulated ring (4). The connecting pin (2) is brazed onto the aluminium lead. The contact resistance is very low and consequently this will increase the life span of the joint.

Title: Fluid volume measuring instrument with digital display - uses two meshed gears with opto-electronic transducer and counter
Inventor: SCHUMACHER HANS
IPC: G01F3/10
Filed: 1975-12-04
Abstract: The fluid volume measuring apparatus consists of a pair of meshed gear wheels (2)(4) running virtually frictionless on axles (6)(8) set in a support plate (12). The assembly is housed in a sealed chamber.

Title: Soldering process for circuit board - protectively coats those conductor paths not requiring soldering and tins others
Inventor: KUENZIG HERBERT
IPC: B23K35/22
Filed: 1976-02-12
Abstract: The soldering process, for circuit boards, chemically treats those conducting paths that are not to be soldered so that an insulating coating is formed over them that prevents their being wetted by the solder and provides protection against corrosion. The soldering eyes and the metallised through-connections are covered with a protective coat of tin that inhibits the action of bichromate. The circuit board is then treated with a bichromate solution and finally with a silicate solution.

Title: Multiple purpose game board - has varied pattern of parallel lines obtained by transparent rectangular foils
Inventor: TENTUNIAN VAHE
IPC: A63F3/00

Title: Contactless determination of direction of movement - uses two opto-electronic transducers to pick up reflected light, and uses phases of their output signals to determine direction
Inventor: HERBRIG HOLGER DIPL ING
IPC: G01S17/50
Filed: 1976-08-31
Abstract: The movement of the equipment is related to a reflecting object. Reflected light has different intensities depending on position. It comprises at least two opto electric transducers whose output signal phase comparison gives the direction of the relative movement. Reflected light is projected on the transducers (4) staggered in the direction of movement, and their output signals (S1, S2) are converted into rectangular signals. Phases of the two rectangular signals are compared in a phase comparator (7), and binary signals (Z, Z), are delivered, depending on the positive or negative phase shift. They control a display device (9).
