Abstract: HARDBOARD PANEL SIDING     ABSTRACT OF THE DISCLOSURE           Disclosed is an exterior grade hardboard siding panel which gives the appearance of vertically-applied solid lumber planks having a bead and cove detail.  The front surface of the panel has a plurality of adjacent areas which each simulate a vertical solid wood plank.  Each of these areas has a cove recess at one edge and a bead adjacent to a cove at the opposite edge.  The areas are arranged with the cove of one area and the cove adjacent to the bead of an adjacent area, both facing the bead.  The coves are separated from the bead by narrow grooves which provide good breaking points in the design and added damage resistance at the edges of the panels which are joined with shiplap joints.

Abstract: TEMPERATURE MEASUREMENT APPARATUS              Abstract of the Disclosure:           A light source for forming an optical path that extends across a closed vessel and a light receiving unit for receiving light from the light source are disposed outside the vessel.  An element to have its temperature measured lies in the vessel and is provided with a temperature detecting device which consists of a temperature sensor and a light intercepting plate.  The temperature sensor is formed by sticking two concave members of different coefficients of thermal expansion one over the other.  When the element has reached a predetermined temperature, the temperature sensor reverses the concave condition to a convex one.  This causes the light intercepting plate to be turned into the optical path to intercept part of the light from the source.  Thus, the quantity of light received by the light receiving unit changes, and the temperature of the portion is measured through a light quantity - temperature conversion.  Preferably, there are more than one, e.g. three, temperature sensors set to operate at different temperatures and each with a light intercepting plate of different magnitude so that a stepwise indication of the temperature can be obtained.

Abstract: "VERTICAL MOTION COMPENSATED CRANE APPARATUS"         ABSTRACT OF THE DISCLOSURE A relative motion compensation apparatus is provided in a crane having two platforms vertically movable with respect to each other and employing a boom supported on the first platform, a cable depending from the boom and supporting a hook and a winch to move the cable.  The relative motion apparatus uses a fluid cylinder and piston assembly secured to the crane boom.  Sensing means generate a signal responsive to the relative vertical movement of the two platforms.  The signal is used to control the position of the piston in the cylinder to thereby vary the vertical separation between the hook and the boom.

Abstract: ABSTRACT OF THE DISCLOSURE         A lubricant is provided to help in drawing containers such as cans from tinplate or coated tin free steel and to assist the metal forming process during drawing.  The lubricant is formulated to permit a post spray without removal of the lubricant thereby eliminating washing and drying the container before post spraying.  Post spray coatings are solvent or water based and are necessary to protect the container from the harmful effects of the material carried within the container and in turn to prevent contamination of the product by its container.          A method of lubricating a metal to be deeply drawn  into a sanitary can is explained and includes leaving the lubricant on the can during interior post coating operations.

Abstract: IN-LINE CENTRIFUGAL PUMP                 ABSTRACT OF THE DISCLOSURE A ladder pump for use with a hydraulic dredge to increase the main pump efficiency comprises a casing and a vaned impeller located in the casing and mounted for rotation about a normally horizontal axis transverse to the ladder. The casing has an inlet and an outlet defining respective axes lying in a common plane perpen-dicular to the impeller axis and defining a deflection angle therebetween, with approximately 60° being typical. The diameter of the impeller and the inner dimensions of the casing together define a substantial clearance over at least that portion of an impeller vane's travel be-tween the inlet and the outlet, so that large solid objects entering the pump may pass under the impeller and out the pump outlet.  The impeller may have substantially rigid vanes, or the vanes may be flexible.  The ladder pump fits in-line with respect to the suction pipe, and has an axial extension little wider than the pipe itself. Thus it is readily positioned proximate the suction mouthpiece where it can work most effectively.

Abstract: ABSTRACT           A unitary transparent eyepiece has a planar outer rim and a planar inner viewing zone, the plane of the inner viewing zone being inclined at an angle to the plane of the outer rim.      The angle between the, preferably circular, inner viewing zone and the, preferably circular, outer rim of the eyepiece is chosen such that when the planar outer rim is fitted into the planar socket of a face-piece in a protective device, the inner viewing zone is orthogonal to the line of forward vision of the wearer.  In this way the face piece conforms to the shape of the wearer's head,  an efficient planner and circular seal is obtained between the eyepiece and its socket, and optical aberrations (associated with curved eyepieces) are minimised.      The position of the inner viewing zone relative to the outer rim may be varied according to the clearance required between the eyepiece and the wearer's eye and the type of face piece employed.  Certain eyepieces of this design are reversible and may be used in both the right hand and left hand sockets of a face-piece.

Abstract: IMPROVED CLAMP FOR OPTICAL FIBERS OR THE LIKE            Abstract of the Disclosure An improvement for a cable clamp which is particu-larly adapted for use in connection with optical fiber cables is provided.  The clamp comprises twin hermaphroditic half portions which intermate and axe pivotally movable relative to each other to define two sets of clamping jaws which open and close simultaneously as a result of a scissor like pivot connection.  A locking band such as a threaded nut locks the jaws at one end of the clamp together to securely engage an optical fiber cable sheath and simultaneously to secure an optical fiber of such cable at the opposed end. The improvement resides in the pivotal hinge elements interconnecting the two jaws of the clamp, the hinge elements being formed integrally with the jaw elements in complementary fashion to provide the scissorlike hinge action which facilitates the entry and clamping of the inserted optical fiber and cable by the half portions.  The pivotal hinge elements are spaced from the central axis of the clamp assembly and are totally separated from the optical fiber both during engagement of the cable and upon final assembly.
