Patent EP-0116730-A1 (EP)
Inventor: MURPHY ALAN STANLEY
IPC: G06F3/041
Filed: 1983-01-28
Abstract: A stylus for interactive use with a graphics input tablet provides a user with a tactile response whenever the stylus tip (5) passes through the 'in-presence' boundary of the tablet. The boundary defines the limit of the distance of the stylus above the tablet surface beyond which stylus position signals are regarded as unreliable. The tactile response is produced by a movable mass (2) within the body (1) of the stylus which is propelled by an internal mechanism (9, 10) into a lower end stop (11) as the tip passes through the 'in-presence' boundary towards the tablet, and into an upper end stop (3) as the stylus passes through the boundary away from the tablet. The tactile response experience by a user in each case is different. In an alternative arrangement, the stylus tip (5) is attached to the moving mass (2) and arranged normally to be held retracted within the stylus body (1) but to automatically protrude from the body as the end of the stylus passes through the 'in-presence' boundary.

Abstract: The invention is related to a method and an apparatus for measuring the flow velocity of a flow, stream or jet of molten radiation emitting material, in particular a freely falling jet of molten glass. The intensity of the radiation emitted from a limited section (2, 3) of the material flow is detected by means of two radiation detectors (S1, S2) at two separate locations mutually spaced apart by a given distance (L) along the flow path of the material flow. All pulse-like amplitude variations having an amplitude exceeding a given magnitude are discriminated from the output signals of the two radiation detectors. These pulse-like amplitude variations originate from randomly occurring, local, discrete, short variations in the intensity of the radiation emitted by the material flow caused by randomly occurring inhomogeneities in the material, for instance in the form of air bubbles in a jet of molten glass. The time interval between a pulse-like amplitude variation in the output signal from the upstream detector (S1) caused by an inhomogeneity in the material flow (1) and the occurrence of a pulse-like amplitude variation in the output signal from the down-stream detector (S2) caused by the same inhomogeneity in the material flow, is measured and used as a measure of the time taken by the material flow to travel between the detector locations, for calculating the flow velocity of the material flow. Also the volumetric flow rate of the material flow can be determined by measuring also the diameter of the material flow with the aid of a linear array of photodiodes and calculating the volumetric flow rate on the basis of measured values of the flow velocity and the diameter.

Title: Hydraulic circuit for a load-driving motor

IPC: F15B13/01
Filed: 1984-10-09
Abstract: A load control system is disclosed for preventing the uncontrolled lowering of a load should a line failure occur in a hydraulic system. The system is designed to be used with a hydraulic cylinder having a movable piston therein which divides the cylinder into a head end and a rod end. Attached to the piston and extending out of the hydraulic cylinder is a piston rod which has a load secured to its free end. The load control system includes a source of pressurized fluid, the flow of which is selectively controlled to the hydraulic cylinder by a control valve. Positioned between the control valve and the head and rod ends of the hydraulic cylinder, respectively, are first and second valves each of which is normally biased towards a closed position by a common pressure. The first and second valves are urged toward an open position by fluid pressure taken between the control valve and the first valve and are movable by this fluid pressure in a proportional manner with the second valve being opened first. The second valve is also physically mounted directly to the hydraulic cylinder such that if a line breakage occurs, the load will still be unable to drop.

Abstract: U Akaline waste waters are treated to precipitate harmful organic residues and other contaminants therefrom by a process which involves carbonating the alkaline waste to a pH of 11 or below, adding calcium chloride to convert the carbonates formed in the liquid to insoluble calcium carbonate and cause precipitation thereof, and separating the calcium carbonate precipitate which brings down with it most of the harmful organic materials. The resultant filtrate can be treated by a conventional activated sludge process as found in many municipal sewage systems, and will not harm the microbial system thereof. A separation apparatus of generally inverted pyramidal shape for conducting the process is characterised by downwardly converging side walls (54,56) having upper portion (56) of gradient less than 60° and lower portion (54) of gradient at least 60° to the horizontal.

Title: Methods for decontaminating soil.
Inventor: PETERSON ROBERT L
IPC: D06M16/00
Filed: 1984-05-25
Abstract: A reagent mixture is admixed with soil to first desorb and then hydrolyze and thereby increase the biodegradability of a toxic or otherwise hazardous polyhalogenated organic compound with which the soil is contaminated. Essential constituents of the reagent mixture are: (1) an alkali metal hydroxide, an alkali metal hydroxide/alcohol or alkali metal hyroxide/glycol mixture, or an alkoxide; and (2) a sulfoxide catalyst. The hydrolyzed compounds can be biologically degraded into compounds which pose little if any hazard to the environment or its inhabitants by naturally occurring or artifically introduced Pseudomonas sp. and other microorganisms with adjustment of soil pH (and perhaps orther parameters) to provide a viable environment for the bacteria being carried out after the chemical treatment if inoculation with bacterial cultures is employed. If a mixture of non-biodegradable and biodegradable contaminants is present, a preliminary biodegradation step can be optionally used to rid the contaminated area of the latter before hydrolysis of the contaminated soil with the reagent mixture is undertaken.

Abstract: Une méthode améliorée de traitement d'images utilise une transformée de Walsh-Hadamard modifiée pour éliminer le bruit et préserver la structure de l'image dans une image échantillonnée. Des signaux d'image représentatifs de la valeur lumineuse des éléments de l'image sont groupés dans des rangées de signaux correspondant à des blocs d'éléments d'image. Ces signaux sont photographiés dans des rangées de signaux plus grandes de sorte qu'un ou plusieurs signaux d'image apparaissent deux ou plusieurs fois dans chaque rangée plus grande. Les rangées plus grandes sont transformées par des combinaisons de Walsh-Hadamard caractéristiques de la rangée plus grande en des ensembles de signaux de coefficient. Le bruit est réduit par modification, p.ex. noyautage ou découpe, et par inversion des signaux de coefficient sélectionnés de manière à récupérer les signaux traités, exempts de bruit, représentatifs de chaque rangée de signaux plus petite. Les résultats montrent un rendu acceptable de détails de faible contraste tout en réduisant certains artifices de traitement caractéristiques de la transformée en bloc de Walsh-Hadamard non améliorée.
