Title: Active radio aerial for motor vehicle - has extra filters designed to prevent unwanted signals from entering given signal paths
Inventor: MEINKE HANS HEINRICH PROF DR
IPC: H01Q23/00
Filed: 1975-12-27
Abstract: The active radio aerial is fitted on a motor vehicle. It has the passive circuit of the passive art of the aerial provided with additional filters which protect the inputs of one or both radio paths against the entry of signals from one or more further radio services.

Title: Reaction:type gas turbine - has combustion chambers inside rotary hub discharging via hollow radial blades
Inventor: SINN HELMUT
IPC: F02K7/00
Filed: 1976-02-16
Abstract: Gas turbine has lengthwise or transverse combustion chambers inside a rotary hub. In these a mixture of fuel and air from a compressor, likewise inside the hub but running at higher speed, is burnt, and the hot exhaust gases are discharged radially through hollow propeller blades. The resulting reaction forces causes blades and hub to rotate. Instead of propeller blades there can be adjustable hollow rotor blades on the hub, so that the turbine can be used for driving helicopters. The blades can also form the turbo-fan stage of an aircraft jet engine.

Title: Concrete stair tread made by pouring concrete into a form - to the level of which the concrete is smoothed down after it has set
Inventor: ROEHRS KLAUS
IPC: E04F11/116
Filed: 1976-05-13
Abstract: A concrete stair tread is made by fitting edging strips to a rectangular base plate and filling the trough so formed to the edge with (if necessary, reinforced) concrete. (The base plate and edging may be of pre-cast concrete, though other material could be used). The edging strips are pref. fixed to the base plate with an epoxy-resin or similar adhesive. The pref. method is to take a long base plate, of which the width is the length of the required stair tread, stick an edging strip at one end and then further strips, of double the width, at intervals corresp. to the width of the stair tread. The plate is then sawn through the middle of each double-width strip, and the remaining edging is stuck in place to complete the individual forms. The concrete (reinforced if necessary) is then poured and allowed to set, then smoothed down to the level of the edging.

Title: Boot standing surface swivel ski brake - uses shackle with flap and stop, released by spring tension
Inventor: FRUEH JAKOB
IPC: A63C7/10
Filed: 1976-05-14
Abstract: The ski brake has a brake plate hinged to the side of the ski. The plate is spring-loaded so that it may be swivelled onto the boot standing surface of the ski. This allows the released spring to swivel downwards over the side surface of the ski, and project beyond the lower ski surface. A shackle (15) which may be released by spring tension, is born in the brake plate (2) and has a brake flap with a stop. The brake plate has a recess (11), which accommodates a locking lever (4) fastened to the base plate. The spring tension of the shackle is produced by elastic deformation during turning in its bea rings (16, 17). The engaged locking lever maintains brake plate and shackle in a tensioned position. The released lever may be tilted in a recess (19) by the boot.

Title: Cutting thermoplastics foam mouldings from a blank - by making a cut in three directions with one single stroke
Inventor: ALFTER FRANZ-WERNER
IPC: B26D1/00
Filed: 1976-07-22
Abstract: Thermoplastics foam mouldings are cut out from a blank, e.g., by severing an edge strip, using a cutting tool which enables a "three-dimensional" cut to be effected in one single stroke. The cutter is a steel band which is electrically heated to 200-300 degrees C. The severing occurs by melting the plastics foam along the cutting line, without counter pressure. Clean cuts are achieved even on relatively thick mouldings. The cutting heat also seals the pores of the foam material along the cutting time.

Title: Myocardial force measuring appts. - uses deflection of pin which flexes diaphragm, being insensitive to pressure
Inventor: STROH NORBERT ING GRAD
IPC: A61B5/042
Filed: 1976-10-26
Abstract: Measurement of myocardial force in given muscle fibre layers is performed with a tube (7) in which an internal pin (3) can be deflected relative to the tube through a lateral hole (8). Deflection of the pin is pref. measured by flexure of a diaphragm (5), so that pressure load have no effect. At the same time, temp. or the ECG can be measured by means of a thermistor or an ECG electrode mounted in a bore (6) in the pin. Flexure of the diaphragm is picked up with wire straing gauges (4) connected in the form of half-bridge and arranged so that S-shaped deflection of the diaphragm produces a signal. Diaphragm deflection which occurs under pressure load does not affect the half-bridge. Contraction forces can thus be measured without being affected by pressure.
