Title: Method of dewatering material containing solid matter and unbound water
IPC: F26B5/00
Filed: 1974-07-24
Abstract: 1460318 Dewatering sludge READING & BATES PRODUCT DEVELOPMENT CO EL PASO SOUTHERN CO and BOEING ENVIRONMENTAL PRODUCTS Inc [trading as RESOURCES CONSERVATION CO] 24 July 1974 [3 Aug 1973] 32720/74 Heading C1C In a process for dewatering a material containing solid matter and bound and unbound water the material is mixed with an amine of formula (where R 1  is H or alkyl; R 2  and R 3  are C 1-6  alkyl or C 2-6  alkenyl and the total number of carbon atoms in the molecule being from 3 to 7), the amine having an inverse critical solution temperature in a two phase system with water. The temperature of the mixture is prevented from rising above the inverse critical solution temperature to form a single phase liquid containing the solid, which is then separated from the liquid, for example by filtration or centrifugation. The temperature of the mixture is preferably maintained at 3-8‹ F. below the inverse critical solution temperature and further reduced to 23-28‹ F. below this temperature prior to separation. The process is preferably used for dewatering an aerobic or activated sewage sludge.

IPC: G03C7/14
Abstract: 329,899. Soc. Francaise CinÚchromatique ProcÚdÚs R. Berthon. April 17, 1929, [Convention date]. Colour photography.-A process of reproducing continuously without waterings colourrecord images on a linear lenticular film A by contact printing on a similar sensitive film B consists in passing the films, with their lenticular faces in contact, continuously through a printing gate comprising two adjacent film guideways inclined to each other at a small angle of the order of one degree or less, the gate being fitted with a mask having an aperture C, situated opposite the point of intersection of the centre lines of the films, whose width is not less than that of the picturespaces on the films, and whose height is equal to the quotient of the width of a lenticular element divided by the sine of the angle of inclination of the film guidmvays. The aperture C is illuminated by a source which may be fitted with a condenser, and the arrangement is such that during the travel of the films through a distance equal to the height of the aperture C, the lenticular elements of one film are laterally displaced relatively to those of the other film by a distance equal to the width of a lenticular element, and the pattern of waterings is consequently displaced too quickly to be reproduced on the film B. The films are delivered to and drawn from the gate over two sets of toothed rollers all rotating at the same speed. Specification 317,051 is referred to.

A resistor having a low thermal resistivity coefficient comprises two or more resistive elements of metallic materials connected in series or parallel, there being at least one element having a negative thermal resistivity coefficient below 0.00004‹ C.<SP>-1</SP>and at least one other element having a positive thermal resistivity coefficient, the dimensions of the elements being such that the resultant coefficient of the connected elements is not more than 50% of the lowest coefficient of the elements used. Preferably, the thermal resistivity of the negative coefficient material is below 0.00002‹ C.<SP>-1</SP> and the resultant coefficient of the connected elements is no more than 0.000004‹ C.<SP>-1</SP>.In general, since the negative coefficient is one or two orders of magnitude smaller than the positive coefficient the resistance value of the positive element must be correspondingly smaller than the resistance value of the negative element so that the change in resistance of the positive element cancels out the change of the negative element. Suitable materials for the positive elements are: copper, silver, gold, platinum or palladium-silver alloy (60/40). Suitable materials for the negative elements are: manganin, " Minalpha " (Registered Trade Mark), " Constantan " (Registered Trade Mark) or " Kumanal (Registered Trade Mark). In a particular embodiment described with reference to a diagrammatic drawing (not shown), three pairs of seriesconnected positive and negative elements are immersed in a thermostat-controlled oil bath to give three ranges controlled by a switch, the positive elements being of copper and the negative elements of Minalpha; alternatively, the negative elements may be of Kumanal.

Patent GB-1562995-A (GB)
Title: Arrangement for recognizing sounds
IPC: G10L15/00
Filed: 1976-08-13
Abstract: Sounds or speech signals are converted into an electrical sound and broken down into separate spectral components in a filter bank. These components are integrated over a short period of time and produce a short-time spectrum of the signal. The spectal components are applied, via a corresponding number of parallel leads, to a number of pattern detectors which supply an output signal only if the short-time spectrum corresponds to the pattern adjusted in the relevant pattern detector. To this end, each pattern detector includes two threshold value (window) detectors which supply a signal if the applied input signal lies between two adjustable thresholds. Each threshold value detector is connected to a different output of the filter bank for another spectral range and is generally adjusted to different threshold values. The outputs of the threshold value detectors are combined via an AND-element, so that a signal is produced only if all threshold value detectors of the pattern detector are activated. For each sound or for each phoneme in the case of speech, a pattern detector is provided. When series of sounds or signals are recognized, the series of addresses of the pattern detectors which have successively generated an output signal are stored and subsequently applied to the computer for comparison.
