Abstract: ABSTRACT OF THE DISCLOSURE        This mixing valve for a single spout, single handle faucet provides a stationary valve seat (24) having two fluid apertures, and a valve plate (28), relatively rotatable with respect to the valve seat and pressed against the valve seat surface.  The valve plate has a generally central aperture (31) and a peripheral aperture (or bight) (30).  The arcuate half-circle shape of the downstream outlets (27 and 27A) of the valve seat hot and cold fluid apertures in combination with the placement and shape of the apertures in the valve plate allows the mixing valve to be adaptable to use with either a knob -(53) or lever-type (59) control handle and in back-to-back plumbing installations by simply rotating the valve plate 180° relative to the valve seat upon installation.

Abstract: ABSTRACT OF THE DISCLOSURE           A support for the roof in longwall mining operations includes a gob canopy at the rear of a roof canopy.  The gob canopy can move about a vertîcal pivot and a horizontal pivot by operation of a hydraulic actuator.  To stabilize the support, the gob canopy moves into or out of contact with the roof at the rear of the roof canopy.  The actuators can move the gob canopy to the left or right side of the roof canopy about a vertical pivot so that a skeg member on the upper surface of the gob canopy drags along the mine roof for steering the roof support when it is advanced toward the mine face.  Gaps between the gob canopies of side-by-side roof supports function in the manner of grizzly bars to permit recovery of small pieces of gob roof rock.

Abstract: A B S T R A C T     A continuously cast strand or ingot of metal is cooled as it emerges from the mold by applying a coolant directly to the surface of the strand. In order to prevent distortion at the foot of the ingot due to too abrupt cooling, polymers of molecular weight 104 - 108 are added to the coolant at least during the initial phase of casting. By the addition of poly-mers to the coolant the kinetics of formation and discharge of vapour bubbles as the coolant strikes the ingot surface are significantly altered due to the reduction in the surface tension of the coolant; as a result of this an insulating film of coolant vapour forms on the surface of the ingot thus reducing the heat flow from the ingot.

Abstract: PLASTIC PIPE JOINT              ABSTRACT OF THE DISCLOSURE            A joint configuration for joining two articles of thermoplastic material by thermal bonding using an electrical heating element, wherein a female fitting having a portion with an enlarged diameter receives the end of an inserted pipe on two raised portions constituting lands on the inner diameter of the fitting, and the central annular recess between the two lands receives and positions the electrical heating element which fuses the thermoplastic material.  The two lands,  each compressed against the outside of the inserted pipe by an external clamp, confine and retain the fused thermoplastic material within the central annular recess to effect an increased internal pressure which promotes the formation of an extensive, contin-uous, and sound bond between the fitting and the in-serted pipe.

Abstract: ABSTRACT OF THE DISCLOSURE         A pipe joint for preventing separation comprising a holding member connectable to an annular outer flange formed at the end of a socket and surrounding the outer periphery of a spigot outside the socket, the holding member being annular or being adapted to form an annular shape, the holding member being provided on its inner periphery with a tapered surface increasing in diameter toward the socket; a stopper in the form of a ring divided at one portion and provided with an outer peripheral tapered surface increasing in diameter toward the socket and with engaging edges in circumferential rows on its inner periphery, the stopper being interposed between the tapered surface of the holding member and the spigot outer periphery; and tap bolts extending through the holding member at suitable portions along its circumference for pressing the stopper from outside against the spigot outer periphery.  Because the stopper is thus shaped, the joint is easy to assemble and manufacture.  When the spigot acts to slip off with the tap bolts tightened up, a diametrically constricting force acts on the spigot uniformly circumfer-entially thereof without eny unevenness to reliably prevent separation of the spigot from the socket.

Abstract: ABSTRACT: "Decimation filter arrangement".     A decimation filter arrangement for reducing the sampling frequency of a time-discrete input signal from fi to fu, fu not being a rational portion of fi. For the generation of the required filter coefficients this arrangement comprises clock pulse generators producing first clock pulses ki(.) at a rate fi and second clock pulses au(.) at a rate fu. The arrangement also comprises a coefficients generator in which a deviation component dn is calculated which indicates the ratio between the time interval located between a clock pulse au(.) and the immediately preceding clock pulse ki(.), and the time interval 1/fi between two consecutive clock pulses ki(.). In response to this deviation component this coefficients generator produces N filter coefficients, the mth filter coefficient, m = 0, 1, 2, ....N-1, being equal to an(m) = h ?(dn + m) V0?. Herein the function h(v) re-presents. the impulse response of an FIR-filter, v a con-tinuous variable in the interval - ? < v< ? and V0 a predetermined constant.

Abstract: ABSTRACT   The invention relates to an electronic power overload protection circuit adapted to limit the output power of a signal amplifier with the help of a sensing element part of a feedback circuit for said amplifier and which becomes conductive upon a predetermined maximum output power threshold being reached.  According to the invention the threshold corresponds to a decreasing amplifier output current with a substantially linear slope up to a predeter-mined output voltage value and with a substantially linear lower slope above the value.  A threshold selector is also provided so that the threshold may correspond to a constant amplifier output current.  In this way the threshold can follow a constant amplifier output current limit up to a certain pre-determined amplifier output voltage and only thereafter will additional protection circuitry come into play to cause the limit to decrease as a function of the output voltage current with a constant linear slope.

Abstract: IMPROVED METHOD OF RECOVERING SUCROSE                 Abstract An improved method of recovering sucrose from plant-derived aqueous solutions is provided.  The method comprises contacting an aqueous sucrose-containing solution derived from plant juice, such as sugar cane or sugar beet juice, with aliphatic carboxylic acid having an average carbon chain length of about 2-6, in a concentration sufficient to selectively precipitate a substantial amount of sucrose from the solution.  The precipitate is then separated and recovered and the depleted solution can be recycled.          Preferably the sucrose-containing solution is concentrated to about 55-96 Brix before the contacting and the contacting is carried out by rapidly adding the sucrose-containing solution to the acid in order to assure rapid growth of large sucrose crystals for maximum sucrose recovery.  The sucrose-containing solution before concentrating can be any solution obtained prior to molasses formation; e.g. untreated diffusion juice, prelimed and/or predefecated diffusion juice, purified diffusion juice or even a solution formed by reconstituting from raw recovered sugar.  It may also be waste fluid from a canning operation or the like.

Abstract: SQUARE CONDUCTOR COAXIAL COUPLER                ABSTRACT OF THE DISCLOSURE     A transverse electromagnetic mode hybrid coupler (10) for coaxial lines is formed within a metal plate (12) by milling out channels (16) of square cross-section.  The walls of the channels serve as outer conductors; inner conductors (18, 19) of square cross-section are positioned within the channels.  A diagonally disposed separator (34) includes a window and crosses the intersection of the coupler ports (21, 22, 23 and 24).  The central conductors of the respective coaxial lines are joined by diagonally disposed segments of inner conductor such that each pair of coaxial lines is so joined.  Each pair of lines provides a pair of ports.  The line segments are spaced apart by a spring-loaded separator for rigidily maintaining a coupling distance.  This design provides improved impedance matching and reliable coupling in both amplitude and phase over a wide spectral band.
