Title: Continuously variable differential
Inventor: RYAN THOMAS B
IPC: F16H59/46
Filed: 1988-03-17
Granted: 1991-12-17
Abstract: TITLE               CONTINUOUSLY VARIABLE DIFFERENTIAL ABSTRACT          A continuously variable differential (10) uses a continuously variable transmission (50) that is rotated by drive torque and controlled to vary the speed ratio between its outputs.  These, which previously transmitted power through the transmission, are connected with a pair of drive shafts such as opposed drive axles (17 and 18) that rotate with the transmission under drive power.  Differentiation between the shafts transmits through the transmission via variable speed ratios that control the moment arms, mechani-cal advantages, and torque bias ratios.  This arrangement allows the torque to be distributed according to sensed vehicle conditions.  It can apply more torque to a wheel retaining traction when its opposite wheel slips, and it can apply a larger portion of the torque to wheels bearing more weight or to a faster rotating wheel on an outside of a curve.

Title: Fuse for sub-munition warhead
Inventor: LEVY AMIR
IPC: F42C9/14
Filed: 1988-03-24
Granted: 1992-11-03
Abstract: ABSTRACT     A slider type fuse for a cargo warhead gre-nade. The slider is slidable in a plane normal to the axis of the striker pin and carries additional to the detonator a pyrotechnic device comprising an igniter charge, a booster charge removed therefrom and located in close proximity to the detonator, a delay charge between the two and swingable  striker means which become unlocked in the armed state and are adapted to strike the igniter charge in consequence of centrifugal forces that develop in the course of flight. The delay of the pyrotechnic device is designed to outlast the flight time of the grenade. Whenever the striker does not strike the detonator when the grenade hits the target,  the detonator is initiated by the booster charge of the pyrotechnic device.

Inventor: BABBITT THOMAS J
IPC: G01N1/28
Filed: 1988-03-30
Granted: 1993-12-07
Abstract: ABSTRACT          MICROSCOPE SLIDE AND SLIDE ASSEMBLY Two rectangular slides having front and rear faces are held with front faces facing each other.  Raised end portions on one or both front faces abut and space the front faces by a distance (e.g., 100 to 250 um) conducive for reversible capillary action between the slides.  Raised island portions on one or both front faces are located at corners opposite the raised end portions.  The raised island portions serve to maintain spacing between the front faces, particularly as the ends of the slides opposite to the raised end portions contact an absorbent material.  An opening between the raised island portions permits liquid to enter and leave the gap between the front faces.

Title: Headlight aiming and light pattern testing apparatus and method
Inventor: HOPKINS ROSS E
IPC: G01M11/06
Filed: 1988-06-22
Granted: 1992-05-05
Abstract: ABSTRACT An apparatus and method for aiming vehicle headlights and for visually displaying the illumination patterns of vehicle headlights. The apparatus focuses the light beam on a screen and includes a video sensor for sensing the intensity of the light in each cell of a matrix of cells overlying the focused light beam and for generating an electrical signal for each cell indicative of the position of the cell and the intensity of the light beam in each cell and a computer for comparing at least some of the electrical signals to each other and with established criteria to determine whether the headlight is aimed within a prescribed degree of accuracy. The same apparatus may be used to describe the illumination pattern of a headlight by visually displaying at least some of the electrical signals, i.e. the light intensities and their locations, for example on a printer or CRT. The conformance of headlight aiming and illumination to established standards can be easily determined by including steps in the computer software to apply the applicable criteria. The aiming conformance tests may produce error signals for controlling powered screwdrivers to correct errors in aiming. The apparatus preferably includes a centering indicator for centering the headlight relative to the lens by comparing electrical signals produced by discrete light intensity sensors disposed around the periphery of the lens.

Title: Process for curing thick-walled articles
Inventor: MATTSON WILLIAM F
IPC: B29C43/52
Filed: 1988-09-23
Granted: 1993-04-06
Abstract: PROCESS FOR CURING THICK-WALLED ARTICLES                ABSTRACT OF THE DISCLOSURE The heat-sink capacity of a thick-walled article being cured with a hot liquid supplying heat to one side of the wall, allows the point of least cure (PLC) to receive a higher rate of cure equivalents even after the hot liquid is replaced with a cold liquid. In the mean while, the other side of the wall continues to be heated. Because such a change-over is effected before the PLC has received the minimum number of cure equivalents required to effect a cure at the PLC (a "pre-cure change-over"), a valving arrangement is provided which allows the change-over to be effected without permitting a pressure drop in the bladder sufficient to permit the tire to "blow" be-cause it is as yet uncured when the change-over is effect-ed. Such a pre-cure change-over cannot be made when steam is replaced with water at ambient temperature.

Abstract: DATA BUS CONTROL CIRCUIT AND TECHNIQUE INCLUDING DATA LATCHING FOR OPTIMIZING BUS UTILIZATION            Abstract Of The Disclosure A means and method for optimizing bus utilization is disclosed.  In addition to traditional computer system components, one or more latch circuits are coupled to a computer data bus.  The latch circuits latch data states on the data bus after the bus has been driven to a desired state by a system driver node.  Tri-state drivers are preferred.  Once a data state has been latched, the associated driver may be disabled without affecting the data state on the bus.  The data state may then be sampled at any time, and the integrity of the data state is preserved, until a new data state is driven onto the bus by a driver node.  The latch circuit parameters allow any system driver to readily overcome the latch action, yet preserve the driven data state as logically valid until it is overwritten.  Data sampling from the bus is restricted solely during driver enable periods.  Bus utilization is optimized without undue sacrifices in system power requirements.
