Abstract: A container formed as a clear cylindrical tube having a weighted base is dimensioned to pull stripped line into the tube and stack the line in neat coils using the weight of the line to provide a guiding pull. A removable handle may be provided for carrying the container over land and a tubular extension may be removably mounted on the top of the container for accommodating special fishing conditions such as high winds. The container may be used to transport clothing and other articles as it is carried inside a travel bag.

Abstract: A magnetic disk drive includes redundant data written at a plurality of out of phase angular locations to reduce the latency and enhance performance during a read operation. The loss of recording capacity is reduced by increasing the data density to achieve the same soft error rate standard required for single recording. Dual recording also allows different recording codes to be used at the duplicated locations to thereby have the more highly stressed code words occur at different locations in the data to further reduce the possibility of an error. The redundant recording can be used in one portion of the media and normal recording used in another media portion to enable selection of the recording technique in accordance with the type of data being stored. The size of the normal and redundant recording portions can be controlled by the format operation and the user of the disk drive can intervene to designate the size of the redundant and normal media recording portions effected during the format operation.

Abstract: A propulsion apparatus for coupling to the stern of a boat is provided having at least one afterplane attached to the stern. At least one motor is positioned onto each corresponding afterplane, where each motor has a propeller positioned above the top surface of the afterplane, such that the propeller does not extend substantially beyond the peripheral boundaries of the afterplane to protect the propeller. Each afterplane may be pivotally raised or lowered so that during operation of the motor, the axis of the propellers are parallel with the plane of the water for propelling the boat. The afterplanes may also be pivotally raised or lowered for planing the boat.

Abstract: A door and floor molding which includes a stationary piece and removable piece. When used as a door molding, the stationary piece is attached abutting a doorway or window and when used as a floor molding is attached a distance above the floor. The distance above the floor is dependent upon the width of the mid section of the removable piece. A lip of the removable piece extends above the mid section and is slideably engaged within a clamping pocket of the stationary piece. A stabilizing wall of the removable piece lies substantially perpendicular to the lip and extends on both sides of a plane of the lip. The stabilizing wall engages the wall in a manner so as to press the mid section against the stationary piece and provide a more secure fit. The removable piece may be removed from its position within the stationary piece to aid in painting around or running wires through the molding.

Abstract: A window and door trim assembly which can be used with siding placed against the walls of a house and includes elongated L-shaped strips fit around the casing of the window or door, and hem strips snapped over forwardly protruding flanges provided on the walls of the facing strips. The hem strips are held on the flanges of the facing strips in a locking engagement therewith but with three gaps produced between the facing surfaces of the flanges and hem strips to compensate for expansion of siding due to heat. Plastic fasteners to secure the facing strips to the siding are of such length that they do not screw into the housing wall. A method of assembling the window and door trim is described.

Abstract: An apparatus and method for forming a power transmission member from a thin-walled blank, the apparatus including a pair of dies (84) having opposed work surfaces, and a mandrel (50) positioned between the work surfaces of the dies (84) for receiving a blank (52) to be formed and rotated upon movement of the work surfaces of the dies in opposite directions during a forming operation. The mandrel (50) includes a work surface for cooperating with the work surface of the dies (84). Notch forming projections (70) on the work surfaces of the dies (84) cooperate with the work surface of the mandrel (50) for roll punching notches (72) through the blank (52) as the blank (52) is rotated between the moving dies (84).

Abstract: A pump jack pole is comprised of an elongated metal tube of rectangular configuration and a resiliently yieldable elastomeric strip which is secured to one side of the tubing. The tubing is comprised of an aluminum extrustion whereon there is formed a plurality of longitudinally extending closely-spaced plarallel protrusions. The strip is formed with a plurality of similarly spaced longitudinally extending grooves of complementary configuration to the protrusions which are interdigitated with the grooves.

Abstract: A coupling arrangement for coupling a guard post to a scaffold platform. The couples includes a brace for attachment to the guard post. A plug member is carried by a portion of the brace and extends perpendicular to the post. The plug includes a resilient sleeve through which extends a bolt. The bolt passes externally of the brace for external manipulation thereof. The plug member is inserted into a hollow run of the scaffold. The bolt is tightened, whereby the sleeve becomes constructed and secures itself within the rung.

Abstract: A clamping device for securing a pole within a U-shaped yoke includes a clamp member pivotally supported on the yoke to open the latter so as to introduce therein an upright pole or to close the yoke to clamp the pole therewithin. The clamp member is provided with a pivotable locking member which has a hook insertable into a slot formed in a side wall of the yoke. A bolt threadingly passes through a hole in the clamp member and is terminated with a bearing plate which abuts the pole to clamp it within the yoke. The yoke is pivotally connected to an X-shaped brace which is fastened to a support surface to support the pole relative to this surface.

Abstract: A pump jack for traveling up and down a pole includes a frame member which supports a lower shackle having a front and a rear gripping rods applying a clamping force for gripping the pole. A pump arm pivotally supports and operates an upper shackle also having a front and a rear gripping rod for clamping the pole. The lower shackle has a single U-shaped yoke pivotally supported on and biased to a support arm to improve the leverage for operating the lower shackle. The upper shackle is provided with a freely rotatable roller mounted on the upper shackle so as to space the bitting front rod of the upper shackle from the pole to permit stepping up of the upper shackle. The usual tension springs on the upper shackle are eliminated to thereby permit less force needed for its operation.

Abstract: A pump jack for traveling up and down a pole includes a frame member and upper and lower shackles supported on the frame member. A pump arm is coupled to the pump jack and is operated for alternatively gripping the pole by the upper and lower shackles. The upper shackle has a helical rod which is cranked by a handle to roll along the surface of the pole. To prevent an accidental rolling of the helical rod and thus slipping of the pump jack down the pole, and anti-spin friction device including a rubber disc and a bolt acting thereon, is provided on the end of the helical rod opposite to that which carries the handle.
