Patent ZA-835206-B (ZA)
Title: Non-destructive testing system employing a liquid crystal detector cell
Inventor: SANDHU JASWINDER S
IPC: G01H9/00
Filed: 1983-07-18
Abstract: An ultrasonic imaging system for use in non-destructively testing objects, includes a source (10) of ultrasonic energy, a liquid crystal detector cell (16) and an optical viewing system (20, 22, 24). The cell includes a pair of acoustically transmissive covers (32, 34) which encase a nematic liquid crystal material (30). The material exhibits an acoustic-optic effect, and in particular, exhibits birefringence in response to ultrasonic energy. The cell construction, geometry, and material are acoustically matched to the frequencies of the isonifying ultrasonic transducer so as to optimize the performance of the cell. The covers are substantially acoustically transparent to ultrasonic energy incident on the cover at both normal and oblique attitudes. The acoustic impedance of the covers match as closely as possible to that of the coupling medium. The average alignment of the liquid crystal molecules, as indicated by the director, is selectively aligned to be oblique to the ultrasonic beam and by reason thereof the cell exhibits high sensitivity and high image resolution in the "non-streaming" region. Electric field enhancement may be used to cooperate in aligning the liquid crystal molecules and to enhance the resolution and sensitivity of the image.

Title: Apparatus and methods for speech analysis
Inventor: HOLMES JOHN NICHOLAS
IPC: G10L19/02
Filed: 1985-11-12
Granted: 1988-10-05
Abstract: Input signals representative of speech are unreliable as inputs for speech recognition if processed conventionally by, among other processes, filtering into separate frequency bands. Further processing according to the invention takes the output from a filter bank and after operations of rectification and integration provides a process of median filtering and smoothing which significantly reduces the sampling rate of the filtered signals while retaining the important acoustic features of the input speech.

Title: Flushing tank for toilets
Inventor: MARCOLONGO SILVANO
IPC: E03D/
Filed: 1990-02-02
Granted: 1993-09-03
Abstract: The invention concerns a new flushing tank for WC pans or squatting lavatories. Water from the mains enters the flushing tank, which is fitted with an elastic diaphragm. Greater pressure than the atmospheric pressure is created inside the flushing tank facilitating flushing. It is well-known that current flushing tanks have a float, which stops the water entering the flushing tank when the former reaches the set level. Therefore the water inside the flushing tank is at atmospheric pressure and flows down into the WC pan at a speed in relation to the height on departure. This invention, takes advantage of the mains pressure to
