Abstract: An assembly for immobilizing the head of a trauma victim intended to be positioned on a stretcher board. The device includes a first sheet of flexible material which is to be mounted so that, when it is affixed to the board, a pair of normally-flaccid, open-sided loops are defined therein. The loops are intended to be at locations which straddle an intended location of the trauma victim's head. A pair of compressible blocks are also included. Each block is intended to be received within one of the normally-flaccid, open-sided loops. A block can be easily inserted into, and removed from, its corresponding loop because the loops are open-sided in nature. When the compressible blocks are received within the loops and constrained thereby, the blocks, together, define a seat in which the head of the trauma victim can be positioned.
Abstract: A power clamp is provided that clamps the workpiece when the piston rod is retracted into the cylinder housing thereby preventing damage to the rod and clamp components that could occur from weld flash and other debris created while operations are performed on the workpiece.

Abstract: A jack for forcing adjoining boards or sheathing into close proximity or contact with one another and holding them in such a position while they are fastened to supporting joists or rafters. The device consists of a housing that is adapted to engage the joist or rafter. A slot is formed lengthwise in the housing and adjoins a side of the joist or rafter. A wedge is positioned in the slot so as to wedge itself between the housing and the supporting joist or rafter and hold the tool in a fixed position relative to the supporting joist or rafter. A lever is pivotally attached to the housing and has an attached pusher to engage the edge of a board or sheathing and move it into proximity or contact with an adjoining board that has been already affixed to the joist or rafter. A simple wedge or inclined plane minimizes the number of moving parts in the invention and produces a wedging force proportional to the force being used to move the board in contact with an adjoining board.
Abstract: The tool of this invention is used to insert an O-ring into a cylindrical housing. Generally, the slot for seating an O-ring is internal of a housing and requires some manipulations to properly seat the ring. This invention provides a tool with an adjustable stop that limits the insertion of the tool to the exact location of the slot in the housing where the O-ring will seat. The tool has a loading assembly and a movable trigger assembly that properly loads, positions and moves the O-ring when appropriate.

Abstract: Apparatus for mutually aligning a pair of surfaces, e.g. kitchen counter-tops, has first and second groups of suction cups for gripping engagement with respective ones of the surfaces and a support structure connecting together said first and second groups of suction cups. The support structure includes adjustably laterally displacing the second group relative to the first group to thereby relatively displace the surfaces towards one another in a first direction at least substantially parallel to the surfaces and an adjustable abutment on the support structure for displacing one of the surfaces relative to the other in a second direction at least substantially perpendicular to the surfaces.
Abstract: A mechanical jack comprising a base with wheels attached thereon for moving the jack, a primary arm of which an end is pivoted on the base so as to be rotatable with respect to the base, a secondary arm of which an end is pivotally mounted approximately on the middle of the primary arm so as to be rotatable with respect to the primary arm, and a threaded rod threadingly connecting between the free ends of the primary and secondary arms so that when the threaded rod is rotated, the free ends of the primary and secondary arms move towards or away from each other, depending upon the rotation direction of the threaded rod. With the pivoted ends as the rotation centers, moving the free ends of the arms will also heighten the free end of the secondary arm so as to lift a vehicle supported thereon.

Abstract: A method for inserting cables within a pipe characterized by closing one end of the pipe with a cap having an opening or port for introducing a flow of an agent and having a plurality of closed entry channels, opening one of said entry channels and inserting a cable through said opened entry channel while applying a flow through the opening or port so that the flowing agent creates a turbulence within the pipe for engaging the surfaces of the cable inserted through the opened entry channel to carry said cable along the length of said pipe.
Abstract: A screw-type jack including an auxiliary screw barrel which is engaged with a ram cap at the uppermost stage. With that construction, this screw-type jack also has such function as to overlay an upper portion of a casing by the auxiliary screw barrel when the jack is contracted, in addition to widening the lift of the jack, whereby the case can be free from dirt and protected from damage.
Abstract: A flexible, axial compensating, rotary driver-type tool bit for adjusting fasteners or adjustment screws for use with a driver motor or other automatically driven system, the driver having flexible couplings between a base member, a driver member and a collar. The driver capable of both axial adjustment and lateral adjustment in response to the relative position of the fasteners or adjustment screws. The driver member moves axially within a collar relative to the base member within limits established by a limiting pin extending from the driver member and cooperating with an elongated slot in the collar and by the space between the base member and the driver member. The driver member and the collar also adjust laterally relative to the base as permitted by a spring connecting the collar and the base member.
Abstract: A sheath for optical fibres comprises a compound sheath having an inner sheath of high modulus and density, and an outer sheath layer of low density material. The outer sheath layer may be of foamed polyethylene and the inner sheath of polypropylene, both conveniently formed by extrusion.
