Abstract: METERING PUMP     ABSTRACT OF THE DISCLOSURE     A fluid pump for location within a reservoir and which is operable with rise and fall of liquid within the reservoir.          The pump comprises a tube of a resiliently deformable material, an abutment surface which is engaged by the tube and a float device which is mounted to the tube.   Liquid entering the reservoir causes upward movement of the float device and such movement of the float device causes increasing engagement between the tube and the abutment surface.   The increasing engagement between the tube and the abutment surface causes the tube to deform resiliently and a localised reduction in the contained volume of the tube is thereby effected to cause expulsion of fluid from the tube.  Conversely, as the liquid level falls in the reservoir, the float device moves downwardly to reduce the extent of engagement between the tube and the abutment surface, so that the tube tends to resume its initial contained volume.

Abstract: ABSTRACT OF THE DISCLOSURE A wind turbine comprises a vertical, rotatable shaft and at least one arm, preferably two or more arms, extending radially outwardly from the shaft and rigidly connected thereto at one end.          An aerofoil-shaped blade is connected to the other end of each arm and has a normal operating position in which the blade chord line at the point where the blade connects to the arm is generally normal to a longitudinal axis of the respective arm.  The lead-ing edge of the blade is disposed at a fixed acute angle relative to the vertical at all rotational speeds of the blade about the axis of the shaft.  The arms preferably also have an aerofoil-shape.  An overspeed control mechanism is provided to prevent the blade and arm from rotating beyond a predetermined speed limit about the shaft.  The control mechanism includes a hinge mount pivotally connecting the blade to its respective arm.  The blade is able to move under excessive speed conditions from the normal operating position to a position wherein the blade creates increased drag.  A spring arrangement restores the blade to its normal operating position when the speed limit is no longer being exceeded.

Abstract: ABSTRACT OF THE DISCLOSURE A tool is provided for cutting a textile cot from an associated mandrel.  A method for making such tool is also provided.  The tool is particularly adapted to be attached to one of a cooperating pair of machine components which are relatively movable toward and away from each other and a mandrel with a cot to be cut supported on the other component.          The cot may thus be cut axially along its length upon relatively moving the components towards each other.  This thus provides a tool of simple and economical construction which may be utilized with a simple machine, such as a hand press, commonly available at a textile processing facility for the purpose of removing a cot from its associated cot-supporting mandrel in a minimum of time without damage to the mandrel.

Abstract: ABSTRACT        Apparatus for retracting and securing the grapple head (22) of a grapple skidder (10) for travel over rough terrain in an unloaded condition.  A pair of cables (94, 96) of equal length are attached to the grapple head at points laterally spaced from the vertical pivot axis of the grapple head.  The cables extend through a guide member (100) on the grapple arch (20) and are wound together onto a winch (24) mounted on the skidder frame (14).  The guide member has a relatively large opening (106) flared outwardly and downwardly facing the grapple head, and a relatively smaller opening (108) flared outwardly and downwardly facing the winch.  In normal operation of the grapple, the cables are left slack.  When the grapple head is to be secured for travel, the cables are winched in.  Since the cables are wound together, they retract together regardless of the relative tension in each cable, such that the grapple head automatically becomes centered square to the back of the skidder when the cables are winched in.  In the retracted position the flared guide tends to pull the spaced ends of the cables attached to the grapple head inward toward the longitudinal centerline of the skidder to minimize lateral movement of the grapple head during travel.

Abstract: ABSTRACT OF THE DISCLOSURE This invention relates to a trench shoring assembly which includes a pair of spaced-apart side walls for vertical disposition within a trench. Spreader pipes and spreader collars interconnect the side walls and allow limited pivotal movement between the side walls.  Each side wall includes outer and inner metal plates connected to a horizontally extending hollow top beam which extends longitudinally along the top of the side wall, two intermediate beams parallel the hollow metal beam and a bottom beam. A hardwood insert is disposed within the top beam to prevent the collapse of the hollow metal beam. A number of hollow beams extend perpendicularly to the horizontal beams and ribbed members extend perpendicularly to the horizontal beams. The side walls of the assembly have a tapered bottom portion which defines a triangularly shaped pointed lower extremity extending between the ends of the bottom portion. A metallic bar is disposed at the pointed lower extremity and extends between the ends of the bottom portion and protects the bottom of the side wall against abrasion.  A U-shaped member is welded to the main frame, and, in turn, a spreader collar is welded to the U-shaped member so that a force applied to the spreader collar is transferred directly to the main frame.  Each spreader pipe spaces the side walls apart between two spreader collars to which the spreader pipe is attached by spreader pins.  Lifting rings are slidably attached to the spreader pipes for lifting the assembly.  A plurality of flanges extend from a spreader pipe and are connected by locking pins to mating flanges which extend from another spreader pipe of another vertically stacked trench shoring assembly.

Abstract: ABSTRACT     A refractory sheathing made from insulating shapes for vertical support members, in particular riser pipes, in heat-treating furnaces, e.g., pusher furnaces, comprises an inner  layer made from a refractory, fibrous, insulating material,or an appropriately shaped article, surrounding the support members and an outer layer of positively interengaging, refractory, shell-shaped shapes of, for instance, the same height throughout, surrounding said inner layer. To avoid a large number of different shapes having to be correspondingly expensively manufactured in different moulds to match support members of different dimensions and double pipes, it is proposed that only equal-leg angle pieces of different leg lengths, in particular two different angle pieces, and straight intermediate pieces of different widths, in particular only two or three widths, be provided as shapes. All shapes have grooves on two contiguous sides at right angles and matching tongues on both of the other contiguous sides at right angles. The inner layer surrounding the support members is formed from set-up, substan-tially rigid, flat insulating boards.
