Title: Abs variant nominal hold pressure
Inventor: LEPPEK KEVIN G
IPC: B60T8/58
Filed: 1990-01-29
Granted: 1994-05-31
Abstract: ABS VARIANT NOMINAL HOLD PRESSURE          Abstract of the Disclosure A brake control system is described that maximizes the braking efficiency of an under-damped actuator, such as a motor-driven linear screw.  When an incipient lock condition is detected, the system determines the optimal brake pressure, relieves brake pressure and measures the duration of the pressure release.  When the wheel is approaching recovery, but has not yet substantially recovered, the system holds brake pressure constant at a value calculated to represent the amount of pressure remaining at the wheel brake.  This calculated hold value is based upon the measured optimal pressure and the measured release duration, and allows the wheel to continue to reaccelerate towards recovery while preventing unnecessary pressure relief.  Once the wheel recovers, the system reapplies brake pressure to a substantial fraction of the optimal pressure without over-exciting the actuator and over-shooting the desired pressure.

Title: Dual diameter needle with a smooth transition
Inventor: PURDY EDMUND R
IPC: A61M5/32
Filed: 1991-09-12
Granted: 1998-05-26
Abstract: A needle cooperates with a tip cover that coaxially fits about the needle and slides axially relative thereto. A thin walled tube of the needle has a shank portion extending from the proximal end toward the distal end and a tip portion extending from the distal end toward the proximal end.  The tip portion has a diameter that is larger than the diameter of the shank portion. The needle includes a transition zone between the shank and tip portions wherein the axial distance of the transition zone is about an order of magnitude greater than the difference in the diameters of the tip and shank portions. The tip portion includes a bevel extending from the distal end toward the transition zone as a sharpened edge to ease insertion. The cover includes a bearing and a  tip protecting part.  The bearing is sized to coaxially fit about  the  shank  portion  and  slide  axially  relative thereto. The difference in the diameters of the tip and shank portions is such that the bearing can not slide distally over the transition zone. The cover is positioned on the needle to locate the tip protecting part over the sharpened edge when the bearing is at the transition zone. The transition zone is shaped frusto conically and is located - between the shank and tip portions. The frusto conical shape is at angle relative to the axis of the needle  due  to  a difference  in the  first  and  second diameters  thus  providing  a  diametrical  imperceptible change.

Title: Flat woven papermakers wet press felt base fabric which is joined endless
Inventor: BENNETT JINAN G
IPC: D21F1/00
Filed: 1992-02-18
Granted: 1995-10-10
Abstract: A seam for a papermakers wet press felt having a flat woven base  fabric with the crimped yarns oriented in a lengthwise or machine direction is disclosed.   Orientation of the crimp in the machine direction lends itself to an analysis of the crimps per square inch based upon the crimp length and warp end count.  Utilizing the crimps per square inch figure, it is possible to establish the approximate minimum length of the join in the machine direction.   The minimum machine direction length,  in inches,  of the join area is approximated by the equation:  approximate joined length equals 500 divided by the crimps per square inch in the repeat pattern of the woven base fabric.

Title: Fluorescent-lamp leadless ballast with improved connector
Inventor: VAN WAGENER RAYMOND H
IPC: H01R13/66
Filed: 1992-04-03
Granted: 1999-09-14
Abstract: A half-connector body has lateral ears that fit in small notches in the ends of the side walls of a ballast can, preferably at the top. An end wall, if present, traps the ears longitudinally in the notches; resilience of that wall, and of its attachment to the can bottom, enhance tight longitudinal fit. The half connector (a receptacle) presses against, and partly protrudes through an orifice in, the end wall (if present).       Outside the ballast, in a new fixture, a jack slides freely in the receptacle to make wiring-harness connections.      The jack has a ratchet-like manually operable hook to secure the jack until manually released. Each contact or lead in either half connector is preferably provided with individual strain relief by permanent deformation (as for example using a die punch) without heating or plastic flow) of the connector wall inward, to displace material irreversibly around the wires. In either the jack or receptacle, cylindrical female contacts make smooth wiping contact with bared ends of standard fixture wires held in the opposite half connector, serving as pin contacts. If the female contacts are in the jack, a person may replace conventional ballasts with this new one, by cutting and baring the old harness wires and inserting them individually into the receptacle. Alternatively, for field retrofit a jack can be supplied, e.g. with poke-in wiring.

Title: Control apparatus for washing machine
Inventor: KURODA KOUICHI
IPC: D06F103/20
Filed: 1993-01-21
Granted: 1996-05-21
Abstract: The control apparatus of the present invention is used for a washing machine in which a photosensor having a light emitting element and a light receiving element opposite thereto, detects the degree of light transmission in washing water, and in which, based on variations of the degree of light transmission in washing water thus detected, the respective steps of washing, rinsing and draining are controlled.  Correction is made such that the photosensor presents a predetermined sensitivity to set a current which flows in the light emitting element, after which a washing operation is started.  After drainage, when the next water supply operation is started and the level of water thus supplied reaches a predetermined level within a predetermined period of time, it is judged that washing water used at the previous washing remains in a washing tank.  Then, control is made such that no adjustment is made of the sensitivity of the photosensor and a standard current flows in the light emitting element.  Thereafter, a washing operation is started.  Thus, the control apparatus of the present invention is adapted such that no influence is exerted upon the degree of washing by variations of the characteristics of light emitting elements and light receiving elements.
