Inventor: GREENWAY JOHN MICHAEL
IPC: D04H1/46
Filed: 1991-01-03
Granted: 1999-09-28
Abstract: An apparatus and related process for entangling a fibrous web which employs columnar fluid jets to eject a continuous curtain of fluid in an entangling station. The web is advanced through an entangling station on a conveyor which supports an entangling member having a symmetrical pattern of void areas. Baffle members disposed in the void areas are provided which include radiused curvatures and define apertures having a frusto-conical configuration.      Dynamic forces in the fluid curtain impact the web in discrete and controlled patterns determined by the baffling members to enhance efficient energy transfer and web entanglement. Textile-like fabrics having a uniform, non-apertured, surface cover are obtained by coaction of fluid curtain and baffle structures.

Title: Ultrasonic air-in-line detector for detecting entrained air in a medication infusion system
Inventor: KOENIG PAUL ANTHONY
IPC: G01N29/032
Filed: 1991-04-04
Granted: 1997-01-07
Abstract: An ultrasonic air-in-line detection system for use in detecting entrained air bubbles in the fluid line of a disposable cassette mounted on a main pump unit is disclosed which can accurately detect entrained air bubbles in any type of fluid, whether clear or opaque. The system uses multiple windowing and air volume number weighting to determine when a threshold count of entrained air in a predetermined number of windows of material pumped occurs, with the alarm being sounded only when this threshold count of air bubbles is present in the multiple window volume.   The system of the present invention thus will detect entrained air while avoiding so-called nuisance alarms.

Patent CA-2046976-C (CA)
Inventor: HANNA RONALD DAVID
IPC: E01F13/02
Filed: 1991-07-12
Granted: 2002-05-07
Abstract: A new attachment plate is provided for securing components of panel assemblies to a mounting post, the attachment plate incorporating a securing hook together with a stop means. The attachment plate includes a projecting hook which mates with a slot in a mounting post structural member. The hook is of a lesser length than the slot in the post, and a further projection as a stop means is provided on the attachment plate which also enters the slot and restrains reversed relative movement between the plate hook and the post slot, so as to limit or prevent undesired disassembly of a panel from the post.      The application of an upward impact to the plate causes a cam surface on the stop means to contact the upper end of the mounting post slot. This deflects the stop means out from the slot, to enable removal of the hook from the slot, for panel disassembly from the post. Also provided is a hooked supporting plate incorporating pairs of flexible presser tabs, to compensate for manufacturing tolerances. The laterally extending tabs engage outer surfaces of the mounting post and provide stabilization of a multi-panel assembly against sway.

Granted: 2001-06-19
Abstract: A printer apparatus for a computer. The printer apparatus is suitable for integral mounting in the computer. The printer apparatus includes a move mechanism in which the ink tank moves relative to the recording head, and the distance of movement (i.e. scan speed) for the ink tank is less than the distance of movement for the recording head. This feature allows the capacity of the ink tank to be increased without increasing the width of the printer. The lower scan speed of the ink tank also means that a smaller motor may be utilized.

Title: Process and device to avoid contamination of tapping steel by flush slag with a tiltable converter
Inventor: STILKERIEG BERTHOLD
IPC: C21C5/46
Filed: 1992-11-13
Granted: 2000-07-18
Abstract: This invention concerns a process for the reliable avoidance of slag contamination of the converter tapping steel by flush slag. In accordance with the invention a plastic, workable stopper made of fire-proof material containing silicic and oxidic components as well as suitable binding agents is used for this purpose. The stopper is introduced so far into the tapping channel with the help of a setting device that its front surface, terminated with a funnel-shaped compression plate, almost aligns flushly with the interior side of the converter, and it fills in the diameter of the tapping channel as a result of being compressed, creating such a plane treat the flush slag occurring during tipping of the converter is reliably directed past the tapping channel. Stopper systems used up to now had the disadvantage that age-dependent enlargements of the tapping channel had a detrimental effect on the functioning of the stopper. The new plastic stopper adapts to a large range of tapping channel diameters in accordance with the process used.

Title: Arrangement of controlling issue timing of a instruction in a vector processor
Inventor: OMATA MAKOTO
IPC: G06F15/78
Filed: 1993-01-20
Granted: 1998-09-01
Abstract: In order to effectively accelerate issue of a RAM read instruction which is to access the same memory block as a preceding RAM write instruction, when the RAM write instruction is issued, a counter initiates counting-up of a value indicative a predetermined time duration.  When the counter counts up the value, the RAM read instruction is allowed to be issued at appropriate timing.  A time duration for which the RAM read instruction is prohibited to be issued, is much shorter than a time duration which expires when the RAM write instruction is completely finished.  Thus, the RAM read instruction issue is not required to wait for the completion of execution of the RAM write instruction as in a known technique.

Title: Regulator valve assembly for a torque converter
Inventor: MCCAULEY PHILLIP F
IPC: F16H61/14
Filed: 1993-02-12
Granted: 1997-10-14
Abstract: A regulator valve assembly adapted to be used in conjunction with a torque converter in a vehicular transmission having a pressurized hydraulic distribution system, a cooling system and a torque converter.  The regulator valve assembly has a stepped valve chamber to receive a spool valve member for axial translation.  The spool valve member defines first, second, third and fourth subchambers within the stepped valve chamber.  Axial translation of the valve member effects selective communication between the subchambers.  A first land on the spool valve member is interposed between the first and second subchambers.  A second land is interposed between the second and third subchambers.  A third land is interposed between the third and fourth subchambers, and a fourth land is exposed to the fourth subchamber.  A first outlet communicates with the first subchamber.  A first inlet and a second outlet communicate with the second subchamber.  A second inlet and third outlet communicate with the third subchamber.  A third inlet port communicates with the fourth subchamber.  The first land exposes a projected area to the second subchamber that is less than the projected area that the second land exposes to the second subchamber.  Translation of the spool valve member controls  communication between the second and third subchambers as well as between the second and third subchambers.  A spring biases the spool valve member in a direction to preclude communication between the first and second subchambers.
