Title: Proportional solenoid valve
Inventor: BARON TIBOR
IPC: F16K31/06
Filed: 1991-05-24
Granted: 2000-10-17
Abstract: An electromechanical valve apparatus has an electrical winding and a magnetic flux circuit defining a flux path therefor which includes a plurality of adjacent magnetic segments. The segments include a generally cylindrical center segment with a fluid passage, an end segment, an outer segment and a magnetic armature member. At least one of the segments is physically translatable within the valve apparatus along the flux path to adjust a portion of one of the magnetic segments that is in the flux path and the extent of an air gap adjacent the translatable segment.      The apparatus includes a non-magnetic seat member which is located near or at the paint of highest flux density along the longitudinal axis through the electrical winding. The armature is preferably an elongated member with its closed end located within the electrical winding near the non-magnetic seat member.      The seat member and armature are enclosed within a chamber defining body such as the bobbin. In an alternative embodiment, a flat disc member is located at the base of the armature. The flat disc is retained within the base of the armature. When no current is flowing in the winding, the flat disc member rests against an armature seat formed in the chamber defining body and prevents leakage of air from the fluid chamber. A further alternative embodiment allows ready calibration of the valve apparatus via a calibration fixture adopted to translate one of the magnetic segments within the flux path.

Title: Retroreflective sheet
Inventor: ROWLAND WILLIAM P
IPC: G09F13/04
Filed: 1992-03-31
Granted: 1998-08-11
Abstract: A retroflective material retroreflects a white coloration for light beams impinging thereon at night and appears to have the coloration of the underlying support in daylight.  This material utilizes  retroreflective  sheeting having closely spaced microretroreflective formations on one surface, and a transparent adhesive in a pattern over that surface so as to leave the predominant portion of the surface  free from adhesive.   A transparent backing element is adhered to the sheeting by the adhesive, and it extends in a plane generally above the  formations  to  leave  the  formations  in  the predominant surface area exposed to the atmosphere thereabout. Light rays entering the the other surface of the sheeting and impinging upon the prisms of the predominant surface area are retroreflected by the interface with the atmosphere, and those impinging upon the formations in the area coated by the adhesive pass through the adhesive and the backing for reflection and refraction from the underlying surface, thereby evidencing its color in daylight.

Title: Multiprocessor system for conducting initial processing for shared circuit
Inventor: KONDOU SEIJI
IPC: G06F15/16
Filed: 1992-07-24
Granted: 1999-03-02
Abstract: A multi-processor circuit having a plurality of microprocessors coupled to a shared circuit includes an OR Gate for receiving read signals from each of the microprocessors, and a D-type flip flop which toggles an initial processing permission signal between a permission state and an inhibit state. When power is initially supplied to the circuit, or upon receipt of a reset signal, the initial processing permission signal is set by the D-type flip flop to the permission state. In this condition, the first microprocessor to recognise the permission state of the initial processing permission signal issues a "read" signal and performs an initial processing operation. In response to the "read" signal, the OR gate transmits a trigger signal to the D-type flip flop to toggle the initial processing permission signal to the inhibit state, thereby preventing the other microprocessors from performing the initial processing operation. When all of the microprocessors are operating normally, the initial processing operation is ordinarily carried out for the shared circuit by the first microprocessor to generate a read signal. When a failure occurs in one of the microprocessors, the initial processing can is accomplished by another microprocessor to start the operation of the multi-processor system. Consequently, an initial processing operation for the shared circuit can be reliably performed even if one of the microprocessors is operating abnormally.

Title: Device for confining rows of shopping carts
Inventor: FUCHS PETER
IPC: A47F10/04
Filed: 1992-12-24
Granted: 1996-03-26
Abstract: In a device for confining shopping carts, which is in the form of an accessory unit with control and locking devices (30, 40, 50) for known coin deposit systems (20) for one, an external permanent magnet as a control element (30) is disposed at the end of a shopping cart row which, when passing through the magnetic field (M), interacts with the locking elements (40, 50) of the coin deposit system (20) in such a way that it becomes possible to set up the operational states "Release" (ready to operate) or "Lock" (not ready to operate) exclusively.  Therefore, with the appropriate disposition and size of these components there is operational readiness exclusively in the area of the shopping cart row.  This contact-free interaction is easy to realize structurally and can be securely protected from third party intervention.

Title: Ultra-fast multi-section whole body mri using gradient and spin echo (grase) imaging
Inventor: FEINBERG DAVID A
IPC: G01R33/48
Filed: 1992-07-06
Granted: 1996-08-27
Abstract: A fast magnetic resonance whole body imaging method and apparatus. In each of one or more repetition intervals, after an initial NMR RF (90°) nutation pulse a sequence of (180°) RF nutation pulses is used to refocus the RF response into a corre-sponding train of spin echoes (S2, S5, S8). During the time that the spin echoes would normally occur after each (180°) RF pulse, an alternating polarity read-out gradient is applied so as to form a sub-sequence of gradient echoes (S1,S3,S4,S6,S7,S9). Non-contiguous K-space trajectories of the acquired data are interleaved.
