Title: Monolithic hollow waveguide components - made by pressure die casting using tapered cores contg. grooves producing ribs in bore of casting so frequency of waveguide is not changed
Inventor: HIRSCH GERHARD ING GRAD
IPC: B22C9/10
Filed: 1979-03-01
Abstract: The components consist of elbows, branches, circulators etc., and are made by pressure die casting using a core assembled from several parts. The cross-section of each part of the core increases continuously in size towards the outlet ends of the cavities in the waveguide, so that the core can be removed after casting. Each part of the core contains >=1 groove aligned in the longitudinal direction, the size of the groove decreasing towards the outlet of the cavities in the waveguide. The grooves compensate for the alteration in frequency range caused by the conical profile of the core, because the grooves form ribs in the bore of the casting. Conventional waveguides are made by the costly methods of precision casting, soldering, or electroforming; but the invention permits the waveguides to be made by the less expensive method of pressure die casting.

Title: Analogue measurement of low frequency pulses e.g. heart beats - using digital sensor, frequency multiplier and D=A converter
IPC: G01R23/06
Filed: 1979-10-31
Abstract: A method of analogue indication and/or recording of low frequency series of pulses is esp. applicable to heart rate measurement. It involves measuring the interval between two pulse digitally and enables the higher accuracy associated with pulse-to-pulse methods to be achieved with the lower circuit costs associated with integrated methods. The ear frequency measured is first multiplied digitally by several powers of ten and the resulting high frequency pulse signal converted to an analogue signal using a conventional frequency to voltage converter (3). A multiplication factor of 1000 may be used. It may be achieved using a programmable digital frequency divider (1) whose program input is driven directly by the measurement frequency signal.
