Abstract: Title of the Invention AUXILIARY KEYBOARD APPARATUS          Abstract of the Disclosure A law cost auxiliary keyboard is disclosed which is mounted onthe keyboard of a data terminal device comprising a cover member having an array of auxiliary control keys which overlie and engage associated control keys on the keyboard of the data terminal device.  First sealing means are mounted in the edge of the cover member preventing liquids from entering the terminal keyboard.          The auxiliary control keys are constructed to provide a second sealing environment on the cover member.  A shroud secured to the cover member contains any liquid spilled on the auxiliary keyboard.  An opening in the shroud drains the liquid from the shroud and away from the auxiliary keyboard.  Means are provided to releasably secure the cover member to the terminal keyboard to allow the interchanging of auxiliary keyboards to meet changing business conditions.

Abstract: HYDRAULIC COUPLER            ABSTRACT OF THE DISCLOSURE          An automatic coupling device having a body member movably mounted on a mounting plate fixed to the implement, and a sleeve member movably mounted on the body member.  A releasable device between the mounting plate and the sleeve member releasably retains a coupler nipple on the sleeve member, the nipple including a first valve element urged toward a closed position and being movable to an open position.  A valve body is slidably mounted in a bore of the sleeve member, the valve body having a passage with an inlet end for connection to a fluid line, and being movable to a first position to preclude substantially relative movement of the sleeve member and body member for locking of the nipple in the releasable device, and being movable to a second position to allow relative movement of the sleeve member and body member for insertion of the nipple into the releasable device.  A cam is connected to the valve body for sliding the valve body in the bore of the sleeve member and for moving the valve body between the first and second positions.  The valve body includes a second valve urged to a closed position and being movable to an open position, the first and second valves engaging and opening when the valve body is in the first position and the nipple is attached to form a fluid passageway through the valve body and nipple, and disengaging and closing when the valve body is moved to the second position, even when the nipple is attached.

Abstract: A B S T R A C T          A spacing device for spacing individual conductors of an overhead transmission line includes a hub having at least two cavities each opening onto the hub periphery. Each cavity has an associated arm with a conductor clamp at one end and a knob at or adjacent the other end, the knob being received with clearance within a respective cavity to permit limited articulation of each arm with respect to the hub.  An elastomeric bush substantially encircles the arm in the clearance gap between the knob and the cavity wall, and the cross-sectional shape of the bush on opposing sides of a maximum diameter portion of the knob is deformed by compression during assembly of the device such that each half of the bush has a greater degree of pre-compression at the centre of its cross-section that at the ends of its cross-section.

Abstract: ABSTRACT OF THE DISCLOSURE An electro-thermosensitive recording material capable of developing a colour is disclosed.  The recording material comprises a support having an electrically conductive surface and a conductive recording layer formed on the surface of the support.  The recording layer contains a film-forming chlorine-containing polymer.  Dispersed in the polymer is an acid-sensitive leuco dye and at least one zinc compound; the zinc compound is selected from the group consisting of zinc oxide optionally doped with a different metal, zinc hydroxide, zinc sulfide, zinc carbonate, zinc acrylate and zinc stear-ate.  Such a recording material does not develop a colour upon application of impact, rubbing or pressure but only when an electric current is passed through.  Furthermore, the recording layer may be thin but have a high mechanical strength.

Abstract: ABSTRACT:          An analogue-to-digital convertor consisting of n number of series-connected stages.  Each stage comprises means for determining the difference between the values of an input current and a reference current, and transfers the difference, if positive, to an output which is con-nected to the input of a following stage.  Thus, each time a reference current is subtracted from a signal current until the residual current is smaller than the reference current.  Each stage furthermore comprises means for detecting the polarity of the difference between the input current and the reference current, so as to obtain a dig-ital measure of the value of the signal current.

Abstract: "METHOD AND APPARATUS FOR DISTRIBUTING SLURRIES"     ABSTRACT OF THE DISCLOSURE              This invention relates to an improved stationary slurry distributor characterized by a centrally-located standpipe to receive the incoming slurry, a multi-apertured manifold at the base of the standpipe for continuously dis-tributing the contents of the latter into a plurality of separate compartments bordering the periphery thereof, outlets in the bottom of each compartment, stopper-type valves in-dependently operable to plug one of the outlets, and at least one overflow port in the side of each compartment arranged in misaligned relation to the inlet and slurry stream issuing therefrom, these ports being effective to both prevent the escape of the slurry therethrough when the outlet is open and, alternatively, bypass the flow when the outlet from the compartment is closed so as to not increase the flow into and through the other compartments then in use.  The invention also encompasses the novel means for guiding the stopper valve during its excursions between open and closed positions that also provides the means for maintaining it in coaxial align-ment with its seat.  An adjustable coupling also connects each valve to its actuator for effecting axial adjustment of the valve relative to its seat.  The invention also encompasses the novel flow control method which includes the step of by-passing the input into any compartment with its outlet closed so as to not increase the flow into those with open outlets.     Slurry distributors are widely used in industry as a means for supplying two or more, usually several, down-stream processing lines with a thoroughly mixed uniform product from a common source thereof.  There are basically two different types of slurry distributors, the first being the so-called rotating type which does not concern us here and the second, or fixed type, to which the instant invention relates.     - 1a -
