Abstract: A compression adjustment mechanism for a shock absorber includes a screw cam which is screwed into a bore in the endcap of the shock absorber and which abuts the spring seat for the compression or blow off valve spring. Tightening or loosening the screw cam, relative to the endcap, causes the preload of the compression valve spring to increase or decrease, thereby increasing or decreasing. respectively, the compression forces in the shock absorber. The compression adjustment mechanism can act on the spring seat from any direction, thereby eliminating the need to selectively orient the working cylinder and compression head assembly to the outer cylinder and endcap assembly during assembly of the shock absorber.

Abstract: A processing system intrusion and misuse detection system and method includes instructions for and steps of processing system inputs into events and processing the events with reference to a set of selectable misuses in a misuse engine to produce one or more misuse outputs. The system and method convert processing system generated inputs to events by establishing an event data structure that stores the event. The event data structure includes authentication information, subject information, and object information. Processing system audit trail records, system log file data, and system security state data are extracted from the processing system to form the event data structure. A signature data structure stores signatures that the misuse engine compares and matches to selectable misuses. The signature data structure includes an initial state for each selectable misuse, an end state for each selectable misuse, one or more sets of transition functions for each selectable misuse, and one or more states for each selectable misuse, which can include the end state or the initial state. Furthermore, a misuse output and an index are provided such that for each selectable misuse element there is a mechanism for loading the signature data structure.

Abstract: A  power  system  compensator  apparatus  comprising  a  power converter unit that works in series with the transmission of a power system and switching control means for controlling the link voltage (VL I N K ) of the non-power system side.  The switching control means controls the phase of, at least, the fundamental  frequency  of  the  power  system.    The  power converter unit contains a static power converter transformer with phase differences taking place the secondary windings of the power converter unit.   The static power converter unit  is operated in non-PWM or  fixed pulse width ratio.          Switching rate is minimized.  Loss is lowered while economy of operation is improved.  Since the voltage that works in series  with  the  power  transmission  line  is  controlled, direct compensation of system reactance voltage and direct control of line current are performed.  Improved performance thus results.
Patent CA-2165924-C (CA)

Abstract: The  present  invention provides  an  improved  floatation support comprising floatation means consisting of one or more flexible foam tubes having first and second ends. Sling means having first and second sides is provided with connector means at said first and second sides of the sling means. The foam tube(s) may be retained in a U-shape by attaching the connector means to the first and second ends of the tube so that a person can lie or sit on the sling means.          The sling is attached to the foam tube in such a way as to pull the two ends of the tube together.  This creates a comfortable platform on which a person can lie down either in the supine or prone position, typically with the head at the "U" bend in the tube and resting around the middle of the U Bend.  The U bend provides means to support the head in the water, as this is the point of greatest buoyancy.   The weight of the person on the sling is distributed evenly across the sling with the foam tube on both sides, resulting in good floatation characteristics and stability.   A low centre of gravity results because the weight of the user pulls down the centre of the sling.

Abstract: An end body 34 is formed with a chamber 45 having a bevelled surface 62 and a cylindrical wall 60 in a portion thereof. A sleeve 46 is formed with an outward flange 48 at one end thereof and an annular bead 50 near another end 54 thereof. The sleeve 46 is formed with a press fit section 56 between the end 54 and the bead 50 thereof. The sleeve 46 is inserted axially into the chamber 45 of the end body 34 and the section 56 thereof is press fit into the cylindrical wall 60 of the the body with the bead 50 locating on the bevelled surface 62 of the end body. A valve 44 is threadedly attached to am end 58 of the end body 34 whereby a seal 64 of the valve engages the flange 48 of the sleeve 46. Water enters the end body 34 at the bottom thereof and flows into an axial passage 49 of the sleeve 46. If valve 44 is closed, the water will not flow any further. If the valve 44 is open, water will flow through the sleeve 46, the valve, the chamber 45 and out of the end body 34 to other facilities. The height of the end bodies 34 of different style assemblies could be different from each other. Rather than altering the length of the valve 44 to accommodate the different lengths of end bodies 34, the sleeve 46 is made in different lengths to accommodate the different lengths of end bodies.
