Patent CA-2107073-A1 (CA)
Title: Garden hole digger
Inventor: WEDDERBURN JAMES W
IPC: A01C5/02
Filed: 1993-09-17
Abstract: ABSTRACT OF THE DISCLOSURE A  hand operated garden hole digging  device consisting of a rigid  cylindrical cup,  open at  the bottom,  a rigid  flat base above the cup  and to which the  cup is attached, a  rigid handle attached to the base and extending straight up from the base, and an internal mechanism for packing and discharging dirt.    The  purpose of  the garden  hole  digger is  to provide  an efficient and easy way to dig a hole for potted plants and garden bulbs, as an example.  The hole  digger is rested upon the ground with  the handle  held  firmly.   By  applying  a downward  force coupled  with lateral rotations of the handle the cylindrical cup is  driven  into the  earth.   As  the  cup fills  with  dirt the internal mechanism is pushed upward.    To discharge  the dirt  from  the hole  digger the  internal mechanism  is  pushed  downward  forcing  the  dirt  out  of  the cylinder.

Inventor: HIRAO MANABU
IPC: G06F11/30
Filed: 1993-09-29
Abstract: In a CPU monitoring apparatus, a lap time pulse, which is generated by the CPU in response to successive executions of a program, is monitored and determined whether its duration is between maximum and minimum values, or longer than the maximum value or shorter than the minimum value, and a program execution alarm signal is generated when the duration is either determined to be longer than the maximum value or shorter than the minimum value. The apparatus further determines whether the CPU has successfully or unsuccessfully executed a predetermined number of significant steps when the CPU has repeatedly executed the program a predetermined number of times, and generates a step execution alarm signal if the CPU is determined as having unsuccessfully executed the predetermined number of significant steps.

IPC: F16J15/56
Filed: 1994-03-31
Abstract: Abstract of the Disclosure A totally split mechanical face seal being installable and replaceable without necessitating breakdown of the shaft and/or housing.  The inventive split seal is well suited for replacement of packing or stuffing in heavy duty or inaccessible locations.  The inventive seals include a sealing element that seals the primary ring against the shaft and rigidly positions the primary ring in the axial, circumferential and radial directions, and also includes a sealing element which seals the mating ring against the housing and non-rigidly positions the mating ring in the axial direction while simultaneously providing an axial biasing force on the mating ring to provide mating contact of the two rings.  For applications where gross displacements of the shaft relative to the housing are expected, a thrust bearing or a connection is made between the mating ring assembly and rotating elements associated with shaft.          Alternatively, a bearing assembly is provided for maintaining; the axial position of the primary ring assembly and both primary and mating rings are held in approximately-the same positions relative to each other regardless of the gross shaft displacements.

Abstract: A method of connecting a tow vehicle to a trailer having a front axle assembly which pivots about a vertical axis. The method includes the following steps which will be hereinafter described. Firstly, position a drawbar assembly between the tow vehicle and the trailer. The drawbar assembly has a tow vehicle end and a trailer end. The tow vehicle end is mounted to a single articulation point at a rear of the tow vehicle.      The trailer end is pivotally mounted on a substantially horizontal transverse axis thereby accommodating up and down movement while precluding side to side movement of the drawbar assembly. Secondly, position a steering arm assembly between the tow vehicle and the front axle assembly of the trailer.      The steering arm assembly includes a pair of steering arms having tow vehicle ends and trailer ends. The tow vehicle ends are adapted for omni-directional attachment to the tow vehicle equidistant from the single articulation point. The trailer ends are adapted for omni-directional attachment to the front axle assembly of the trailer equidistant from the vertical pivot axis of the front axle assembly, thereby accommodating relative movement of the tow vehicle and the front axle assembly of the trailer while causing a proportianate change in the angular positioning of the front axle assembly of the trailer to maintain correct steering geometry of the trailer relative to the tow vehicle as the tow vehicle turns.

Abstract: A flat woven pin-seamed papermakers fabric wherein machine direction yarns define a series of seaming loops on the opposing fabric ends.  The fabric comprises a system of flat monofilament machine direction warp yarns (hereinafter MD yarns) which are woven  in  a  selected  weave  construction.    In  a preferred embodiment,  the system of MD yarns comprises upper and lower yarns which are vertically stacked.  Selected end segments of the upper and lower MD yarns are removed and yarn segments made of a more durable material are rewoven into the fabric end in the space vacated by the  trimmed upper and lower MD yarn end segments.    Non-loop  forming upper MD yarns  are  preferably backwoven into the space vacated by trimming respective lower MD yarns.   Preferably,  at least the upper MD yarns are   woven contiguous with each other to lock in the machine direction alignment of the stacking pairs of MD yarns and the orthogonal orientation of the end loops.  The seaming loops of the opposing ends  are  intermeshed  and  joined via  a pintle  yarn.    The permeability of the seam area is controlled via the inserting of rectangular stuffer yarns parallel to the pintle yarn.
