Patent BE-905802-A (BE)
Title: Braking energy conversion and reclamation system - uses electrolysis of water to regain energy which is normally lost
IPC: C25B1/04
Filed: 1986-11-21
Abstract: A vehicle or stationary machine which has to be slowed down has a braking system (LS) which converts the potential energy of a moving body into kinetic energy. The kinetic energy is transmitted (Ov) via a coupling (K) to a dynamo (D). The dynamo output is connected via cables (Ev) to electrodes in a water reservoir (W). In the reservoir, electrolysis breaks the water into hydrogen and oxygen. - The gases are channelled (Hb and Ob) to reservoirs (H and O). The gases are then fed to a motor (M) where the recombination chemical energy is converted to useful mechanical energy. The water vapour is condensed (C) and returned to the electrolysis reservoir.

Abstract: ABSTRACT OF THE DISCLOSURE         In pattern recognition systems for determining and recognizing any normalized characters registered in a record medium by means of a character characteristic extractor, the presence and absence of two-dimensional intelligence signals contained within the normalized characters to be recognized is determined by the consecutive scanning of only a single array of light-sensitive elements, while the record medium travels relative to the characters.  Multiple intelligence signals for each group of the character segments developing across the respective elements are combined together in a signal com-pression mode and then introduced into a pattern decoding matrix in order to extract the character characteristic or pattern based upon a combination of the compressed intelligence signals.

Abstract: ABSTRACT A diagnostic test system for detecting .beta.-galactosidase producing micro-organisms is prepared by impregnating one æone of the bibulous material with an aqueous acetone solution of an o-nitro-phenyl-.beta.-D-galactopyranoside substrate; and impregnating a contiguous zone of the bibulous material with a solution of a micro-biologically inert buffer system which will maintain a pH of from about 6.5 to 8.5.  Preferably, the bibulous material contains 1.5 mg of dry o-nitrophenyl-.beta.-D-galactopyranoside and 0.02 millimoles of a buffer which will maintain a pH of 7.4.  Optionally, a waterproof barrier zone and an identifying dye zone may be present.  In use, the impregnated bibulous mater-ial is inserted into a test tube of a saline suspension of unknown organism and incubated for four hours.  The development of a yellow coloration indi-cates that .beta.-galactosidase is produced by the organism being tested.  The diagnostic test system of this invention is stable for one year at 4°C,, at room temperature, and at 37°C.

Abstract: ABSTRACT OF THE DISCLOSURE           This invention relates to an improved tunnel hull for power boat applications.  A tunnel shaped cavity with a downward sloping roof is defined between two identical side sponsons and is interrupted by a longitudinal central hull section.  Each side sponson has three outward directed facets and the central hull section has adjoining left and right facets.  Towards the bow the central section is sharply V'd and has a leading edge which dips below the leading edges of the sponsons and then gradually tapers to a flatter rectangular section towards the stern where the central section is of lesser depth than  the side sponsons.  The forward portion of the central section provides an additional planing surface at low to moderate speeds.  Its intercession into the tunnel increases the hull's buoyancy to reduce "stuffing" into oncoming waves and further serves to strengthen the tunnel roof.  The intermediate facet on each side sponson provides an additional planing surface at low to moderate speeds and hence allows the boat to accelerate more rapidly.  The leading edge of each of the side sponsons forms a reversed "S" curve to allow some air spillage out of the tunnel which, combined with the reduced size of the tunnel  because of the central hull section, reduces the danger of blowover at high speeds.

Abstract: Abstract of the Invention A tuned pipe exhaust for a two cycle internal combustion engine for snowmobiles and the like includes a conically shaped converging megaphone section terminating in a small end tube.  An absorptive spiral muffler unit is co-axially secured to the end tube and includes an inner radial end wall extending radially from the end tube.  The muffler unit attenuates high frequency exhaust noise.  The space between such end wall and the upstream conical wall of the tuned pipe is enclosed with a tubular resonator wall to define a resonator cavity with coupling opening in the end tube.  The cavity and throat opening defines a Helmholtz resonator which attentuates low frequency exhaust noise.  The combination of a low frequency reactive section and a high frequency absorptive section creates an effective balanced silencer operating over the normal frequency spectrum of such engines.
