Title: Rocker arm decoupler for two-cycle engine retarder
Inventor: QUENNEVILLE RAYMOND N
IPC: F02D13/04
Filed: 1988-06-10
Granted: 1994-10-18
Abstract: ABSTRACT           The invention is applicable to an internal combustion engine of the four-stroke cycle type equipped with a compression release engine retarder capable of producing one compression release event and one bleeder retarding event in each cylinder during every two revolutions of the engine crankshaft. This is accomplished by a novel articulated rocker arm assembly including a rocker member and a latch member in which the rocker member, engaged by the exhaust pushtube, is disengaged from the latch member, which acts against the crosshead, after a compression release event has occurred, but remains engaged if a compression release event does not occur.  When the latch member is disengaged from the rocker member, the exhaust valves are held in a partially open posi-tion to produce a bleeder retarding event.  A trigger valve actuated by the exhaust pushtube and rocker member vents the retarder high pressure hydraulic system to initiate the bleeder retarding event.
Patent CA-1288521-C (CA)
Inventor: GRAND ARTHUR
IPC: G06F17/30
Filed: 1988-08-09
Granted: 1991-09-03
Abstract: ABSTRACT       An indexed sequential file is made accessible for random or sequential reading of records while allowing concurrent modification to the file.  Each ordered group of records in the file is associated with timestamps referencing a deletion time of the group and the time that the group was last modified.  During a current search in a group for a desired record, the timestamp referencing a deletion time of the group is compared to a search time established at the beginning of the search.  For a sequential reading the timestamp referencing a last modification time of a group containing the desired record is compared to a respective timestamp corresponding to the reading of the preceeding record.  The comparisons provide indications of whether the group to which the desired record belongs is currently the group to be searched. The most recently modified and deleted groups are stored in cache memory.  When the cache memory is full, an incoming group and respective timestamps replaces the least recent or least likely to be used group and respective timestamps.  The most recent timestamps of replaced groups timestamps are saved in local memory and are used in the comparisons for groups not currently in the cache.

Abstract: Abstract of the Disclosure A method for optically reading data in a sub-stantially planar data field having a plurality of pages arranged in series of rows and columns.  Each page is spaced apart from adjacent data pages by alignment-indicating streets, which are data-free blank areas.  A          CCD area array is positioned and spaced apart in general-ly parallel relation to the data field.  The CCD area array is then moved linearly so that the array is oppo-site a data page to be read.  An initial imaging there-after takes place in order to recognize the streets bor-dering a data page.  Through recognition of the streets, a processor resolves the orientation of the data page relative to the CCD area array.  The processor then transmits a command signal to a control circuit for ro-tational adjustment of the imaging of the data page.

Granted: 1994-05-03
Abstract: ABSTRACT OF THE DISCLOSURE      A fluid-driven pump (10) includes a drive-inlet-valve assembly (54) that alternately directs the flow of cold pressurized water from a pressurized-water inlet (12) into alternate drive cavities (46a and b).  Outlet valves (60a and b) control flow out of the drive cavities (46a and b).          The resulting reciprocation of piston heads (36a and b) draws hot water in through a pump inlet (16) and out through a pump outlet (18).  A valve operating mechanism driven by the piston heads' reciprocation causes both the drive outlet valves (60a and b) to close before the drive-inlet-valve assembly (54) changes its state to redirect flow of pressurized cold water from the cold-water inlet (12).  The drive inlet-valve assembly (54) is provided with a pilot-valve member that permits the drive-inlet-valve assembly (54) to be operated with a relatively low force and without introducing excessive shock and noise.

Title: Dilatation balloon
Inventor: NODDIN RICHARD A
IPC: A61L29/06
Filed: 1989-03-17
Granted: 1994-12-13
Abstract: Dilatation balloon devices that employ a small diameter, torqueable metal tube for introduction of inflation fluid from distal end into a balloon have special features that enable introduction through very small passages. A distal core wire is shown forming part of a guide wire extending into the distal end of the tube . The core wire is fixed at the distal end of the tube, and has a proximal extension bridging across a fluid opening formed in the wall of the tube. The wire extension serves to transfer stress from the distal end of the device, across the fluid opening, to adjacent proximal portions of the tube, to prevent stress build-up at the opening that might lead to fracture of the tube during bending. In various embodiments, the device includes a bushing seal at the distal end of the balloon; a helical coil surrounds part or all of the length of the device, with strategic tapers along its length; a shrink tubing is used rather than a coil; and a pair of cross-wound multifilar coils are employed. A balloon having a very thin wall, even in its transition section, is formed from a specially prepared tubular preform.
