Title: Non-return valve aperture enlarges at increased pressure - for inlet valves of rotary engines and scavenge pumps
Inventor: HRABAL HANS ING
IPC: F16K15/16
Filed: 1975-01-17
Abstract: The non-return valve body (2) is bolted through a distance piece (3) to the inlet pipe (4). The valve seats (6) are in the form of small plates which are clampted between the leaf springs (9) and spacers (8) and the assembly is mounted in the wedge shaped member (5) secured by bolts (7). The leaf springs (9) which form the sealing members of the valve, are of different stiffnesses. At low pressure differences across the valve only the weakest spring lifts off its seat but as the pressure difference increases more springs lift off the seats increasing the area of flow through the valve. This keeps the flow velocity constant and provide better mixing of air and fuel.

Title: Meat tenderiser with specific weight loading - is subjected to impact force via elastic connection
Inventor: SEYBOLD ROLF DR ING PROF
IPC: A22C9/00
Filed: 1975-02-05
Abstract: In a meat tenderiser for the pre-treatment of meat prior to roasting, of the type having a better part designed for striking the meat, the surface of the beating part has a specific weight loading of 0.5-9 p/cm2 and the beater is under the action of a suitable applied force via an elastic connection, the mass of the beater part, which is pref. fixed to a stem of length 10-30 cm with a handle at its other end, being considerably less than 300g. The cost is such as to make it acceptable for household use and the tenderiser neither destroys the cells in the interior of the meat not increases the surface unduly. Loss of meat juices is minimised while the coagulation of the protein enables the remaining juices to be sealed in during roasting.

Title: Belt building appts. for automobile tyres - having building drum belt-supporting intermediate drum, detectors for belt length
Inventor: NAEDLER HEINRICH
IPC: B29D30/30
Filed: 1975-02-22

Title: Calibrated tape measure to be laid in electric cables - with high tensile strength and low stretch capacity for high precision
Inventor: GRIESSER OTTO DIPL PHYS
IPC: G01B3/02
Filed: 1975-03-21
Abstract: Calibrated tape measure to be laid in electric cables comprises a paper strip reinforced with longitudinally extending glass fibres or plastics threads of aromatic polyamide. The fibres or threads may be laid between two strips of paper which are then bonded to each other by adhesion. In an example, a tape measure 6 mm wide tears under a tensile load of approx. 30 N; whereas a conventional tape measure would show a degree of expansion of 2% under this load, the novel tape measure shows a degree of expansion of 0.4% under the same load. The increased tensile strength of the tape measure meets the requirements on an increased rate of mfr. of electric cables, and reduces losses due to imprecise measurements of the cables.

Title: Ski boots with curved soles for easy walking - require ski bindings with wedge shaped sole plates with extension lug
Inventor: ROTHMAYER KARL-HEINZ
IPC: A63C9/084
Filed: 1975-06-30
Abstract: To enable easier walking in ski boots which have rigid soles, the outside surface of the sole is ruved in a longitudinal direction. The ski binding used has a toe clamp and a conventional heel clamp assembly (1). A wedge shaped plate which is part of each clamp compensates for the curved sole. A hinged trigger plate (15") which is attached to the heel wedge plate (15) has an extension lug (18). By stepping into the open ski binding (1), the hinged trigger plate is pressed down so that its nose (18) forces the heel clamp into a locked clamping position, thus the ski boots are fixed to the skis.

Title: Data input system esp. for drawing data - enables control of plant through mimic diagrams with measuring and functional stations
Inventor: BINDEWALD KLAUS DIPL ING
IPC: G06F3/033
Filed: 1976-02-11
Abstract: Data input system, esp. for data representing drawings, has a display with a screen showing image points at grid points defined by coordinate counters. A drawing instrument for geometrical figures selects the grid points and produces a pulse each time it scans an image point. A comparator compares the coordinates of the image points selected by the drawing instrument and produces signals representing the result. These signals are fed to an analyser which derives from them further signals representing the figure drawn by the drawing instrument.

Title: Frequency measurement of heart beat rate - uses count of clock pulses during set number of beats and calculation of reciprocal
Inventor: SCHILLING ERHARD ING GRAD
IPC: G01R23/02
Filed: 1976-09-21
Abstract: The circuit determines the frequency e.g. of heart-beats, measured in beats per minute. During a certain number of events (e.g. ten heart-beats or more), clock pulses appearing during this period are counted. Their repetition frequency is preselected and known. The measurement interval is calculated from the number of clock pulses and their frequency, and divided by the number of events. The reciprocal of this result is obtained and displayed.
