Abstract: ABSTRACT OF THE DISCLOSURE the present invention relates to a solid state color camera in which a solid state imager is combined with a stripe filter and a color processor to obtain a three color electrical signal. The color filter is a composite filter consisting of a first sequence of pass and rejection stripes for one color alternating at the sensor interval and a second sequence of pass and rejection stripes for a second color alternating at twice the sensor interval. In one form of the invention, the imager is a charge injection device, scanned two sensor elements at a time to produce simultaneous but separate odd and even sensor outputs. The color processing network is coupled to these separate out-puts, and uses combination, delay and sampling circuitry to obtain the three color electrical signals. The in-vention is applicable to other forms of solid state imagers including both charge injection and charge coupled devices and to other scanning techniques.

Abstract: MOTORCYCLE FRONT WHEEL SUSPENSION SYSTEM            ABSTRACT OF THE DISCLOSURE     A suspension system for the front wheel of a motorcycle wherein a fork that carries the front wheel is connected to the frame in a manner that the steering axis of the fork in response to front wheel deflection by bumps is displaced parallel to itself relative to the frame.  A specific example of such a suspension mechanism is a double A-arm connection.          Handlebars are rotatably mounted to the frame.  A connection between the handlebars and the fork is made in a manner so only rotation of the handlebars will cause rotation of the fork about its steering axis, and the connection does not affect suspension movement of the wheel relative to the frame.          Examples of the steering connection are a folding bar and a hydraulic system.

Abstract: ABSTRACT A paddle of rigid unitary construction formed in plastics material, for use with boats consists of a hand-receiving portion forming one end-part of the paddle, a longitudinally extending generally planar blade portion of substantially greater length than width forming the other end-part and laterally spaced side members extending longitudinally from the blade portion into the hand-receiving portion.  A rigid lateral hand-grip that is relatively narrow in the longitudinal direction spans the side members at a position longitudinally spaced from the blade portion between the ends of the paddle to define a first aperture between the side members, the blade portion and the hand-grip whereby a hand may be curled around the grip.  A rigid lateral bracing portion spanning the ends of the side members remote from the blade portion in longitudinally spaced manner from the hand-grip to define a second aperture between the hand-grip, the bracing portion and the side members. Both the bracing portion and the hand-grip lie generally in the principal plane of the blade portion.  In use with the fingers of one hand curled around the hand-grip, the hand extends through the second aperture with the lower arm bearing against the bracing portion to restrain the paddle against pivotal movement within the grip while the blade portion is subjected to pressure during propulsion.

Abstract: ABSTRACT OF THE DISCLOSURE:           The calibration of an elongate synthetic thermo-plastic plastics member having a chamber extending lengthwise thereof and having predetermined cross-sectional dimensions and wall thickness (es), is effected by receiving the plastics member from an extrusion die from which it has been extruded and cooling the plastics member by drawing it through a calibrating die in which the surface of the plastics member is subjected externally to a vacuum and to cooling by means of a liquid coolant supplied through passages extending lengthwise through the die, which vacuum is applied to the surface of the plastics member through a plurality of slots opening out from the calibrating die onto the surface, the slots being transversely disposed with respect to the direction of travel through the calibrating die of the plastics member at positions spaced apart at intervals which together span over substantially the whole length of the calibrating die, all of the liquid coolant supplied to the passages being discharged from the passages into the vacuum slots to be withdrawn in liquid form from the die through the slots by said vacuum as it effects calibration of the plastics member whereby the liquid coolant effects direct cooling of the surface as it travels along the slots in a direction across that of travel of the plastics member through the calibrating die.  The invention also provides a calibrating die for use in the production of the above elongate synthetic thermoplastic plastics member having a chamber extending lengthwise thereof, which die is constructed to receive the member from an extrusion die and to cool it and subject the surface thereof to a vacuum as it passes therethrough, the calibrating die being formed of a plurality of parts extending lengthwise thereof, dividing the die at a plane or planes extending parallel to the length direction of the die and together defining a die passage for through travel of the member, which parts are formed with passages extending length-wise therethrough for throughflow of a liquid coolant and, at those surfaces thereof which bound the die passage, with slots opening out from the calibrating die and extending transversely of the length direction of the die at positions disposed over substantially the whole length of the die passage, which passages for throughflow of coolant are connected to the slots whereby a circuit is formed whereby all of the coolant supplied to the coolant passages can be discharged, by means of an applied vacuum, through the slots whereby the coolant effects direct cooling of the surface of the plastics member as it travels along the slots in a direction across that of travel of the plastics member through the calibrating die.

Abstract: ABSTRACT      The disclosure is directed to an improved liner assembly for an ore grinding mill.  the liner assembly is of the segmented type, comprising a first plurality of segments which are mounted directly to the shell of the mill, and a second plurality of segments each of which is secured to an associated first segment independently of the shell.  the first segments are formed from material which is resistant to impact, and the second segments are made from material which is highly resistant to abrasion.  As con-structed, the second segments can be replaced after a period of wear from inside the mill, avoiding the necessity of replacing the first liner segments which requires working teams both inside and outside the mill.  In one embodiment, the second segments are L-shaped and are secured to the first segment by nut and bolt assemblies that are generally aligned with the shell surface to resist shear forces.  In a second embodiment, the first and second segments resist shear forces with a tongue and groove configuration coupled with nut and bolt assemblies that are transverse to the shell surface.

Abstract: ABSTRACT           A monostable, solenoid-operated valve in a passage which bypasses the drilling fluid pressure drop across a drill bit at the lower end of a dril string in a well opens and closes in response to downhole conditions to create pressure pulses in the drilling fluid.  The valve is urged toward a closed po-sition by drilling fluid pumped through the drill string. A larger force is required to open the valve than to hold it open. Current supplied to the solenoid to open the valve is thereafter reduced to a valve sufficient to hold the valve open.  The solenoid is de-energized to close to valve.
