Abstract: ABSTRACT OF THE DISCLOSURE      A new process is disclosed for successively measuring the environmental exposure of environmental indicating devices.  Environmental indicating devices that may be measured by the new process include devices that have at least one variable region of reflectivity and at least one non-variable region of reflectivity.          Upon exposure to chemical, radiation or time-temperature stimuli, the reflectivity of the variable region rela-tive to the reflectivity of the non-variable region is correlated to an incremental change in the environmental exposure of an indicator device based upon a pre-established relationship between the relative reflec-tivity and the incremental change in the environmental exposure of the device.  The incremental change in the environmental exposure of the indicating device is then correlated to a remaining shelf-life or extent of pro-cessing value for a product that undergoes progressive quality changes upon exposure to environmental stimuli.  Other information such as the identity of a product and/or of a material comprising the variable region of reflectivity may be read and determined by the correlation process.

Abstract: JJM/des #4027 EUKARYOTIC EXPRESSION VECTOR     Abstract of the Disclosure This invention encompasses an eukaryotic expression vector constructed from a prokaryotic plasmid by inserting into the prokaryotic plasmid a mediator sequence and a promoter regulator sequence with a restriction endonuclease site for inserting a gene to be expressed.  The gene to be expressed is inserted into the restriction endonuclease site in the promoter regulator sequence and the resulting plasmid is in turn used to transform a eukaryotic cell.  The gene is expressed with or without viral mediation.

Abstract: ABSTRACT OF THE DISCLOSURE      A fluid seal for sealing a space between an internal machine surface and a shaft, having a rigid portion sealing received within said surface and a sealing lip body contacting the shaft, the sealing lip body being bonded to a part of the rigid portion.          The lip body has a primary lip of reduced size, cross-section and flexibility which includes an "oil side" surface facing towards the sealed region, and an "air" side surface facing away from the sealed region, with these surfaces meeting along a primary seal band which is spaced just apart from the associated shaft and is positioned there by pumping elements which have shaft-engaging surfaces as well as "working" surfaces adapted to return leaking grease to the sealed region.          The auxiliary lip is much larger than usual and is spaced axially apart from the primary lip, leaving an annular groove of generally V-shaped cross-section between the two lips.

Abstract: Abstract A strain wave gearing assembly (Harmonic Drive transmission) having a housing encircling a circular spline within which is journalled a flexspline.  The flexspline has an annular array of gear teeth thereon, which flexspline has an inner bore having a diameter defined as D.

The flexspline has a lip which extends longitudinally beyond the distal edge of its annular array of gear teeth by 10% to 40%D.  The lip is of radially thickening dimensions from immediately adjacent the outer edge of the annular array of gear teeth thereon, and from a thickness of about 1%D up to a thickness of about 3%D at the distal edge of said flexspline, to minimize the skewing of the ellipsoidal deflection wave of the flexspline.

Abstract: Title Transmission Shift Rod Interlock System Abstract of the Disclosure A shift rod air interlock system provides a mechanical apparatus for insuring a neutral position in a two-speed air shifted compound transmission whenever air to an auxiliary air shift cylinder is interrupted.  The apparatus prevents the transmission from being shifted into gear whenever an associated vehicle is stationary and when a power take-off unit is operative.  In addition, a two-position air interlock plunger assembly provides a locking plunger which interfaces with a pair of detents in the shift rod, thus insuring that the auxiliary transmission is prevented from being shifted into neutral whenever the air system is interrupted while the vehicle is moving.  In a preferred form, the invention utilizes a shift rod selectively movable between at least three positions, including an intermediate neutral position.

Abstract: ABSTRACT   A cutting tool for improved material removal efficiency over a relatively wide mid range of typically used feed rates is disclosed. In a preferred form of an indexable polygonal cutting insert, a first cylindrical chip control groove of uniform width extends from a cutting edge at each side of the polygon and terminates inwardly from the edge in a second cylindrical chip control groove having a cross section of larger radius but of lesser depth than that of the first chip control groove. The second groove has its largest width at a point substantially midway between adjacent cutting corners of the polygon and diminishes to zero width at each corner of the polygon leaving a web of insert material running along the bisector of each corner angle, thereby providing adequate insert body support for enabling use of the disclosed chip control geometry on both sides of the insert. The cutting edge along each side of the polygon is arcuate with its lowest point relative to a major face of the insert being substantially at a mid point between each corner of the polygon.

Abstract: ABSTRACT           A displacement transducer operable to measure relative displacement between two parts. The transducer comprises a shorted turn induction coil arrangement on one of the parts and, on the other part, a coaxial assembly of two drive coils separated by an output induction coil comprising two coils in quadrature, the drive coils and the output induction coil being inductively linked with the shorted turn arrangement which may be two or more shorted coils end to end.  The transducer is suitable for measuring displacement of a piston rod relative to its cylinder.      The stroke and the bearing support of the piston rod may be such that either drive coil can project beyond the adjacent end of the intermediate induction coil arrangement at either end of the stroke.  The consequent changing impedance of the drive coils can be used to set a datum for displacement measurement and/or control an electrically modulated control valve which controls operation of the cylinder.  Cushioning of the piston rod at either end of its stroke and automatic continuous reciprocation of the piston within the cylinder can be Provided as a result.

Abstract: ABSTRACT             An apparatus for mutual information transmission between an electronic lock and a key uses antenna coils at both the key and lock.  A periodic signal is emitted from the lock and is received by the key upon activation of a key electronics and emission of a coded information signal.  This returned signal received from the lock coil is briefly short-circuited or damped at the key side in order to produce a synchronization switch synchronizing the points in time of the signal appearance.           Electronic converters are provided which, given the pre-condition that the short-circuit signal extends over a plurality of signal pulses, generate a digital signal corresponding to the short-circuit times.

Abstract: Abstract of the Disclosure A pneumatic  actuator  includes an elastic tubular body, closure members sealingly closing its ends and a braided structure made of braided cords reinforcing the tubular body.  The braided structure is expanded in its radial direction and simultaneously contracted in its axial direction together with the tubular body when pressurized fluid is supplied into the  tubular body.   According to the invention the braided  cords  of  the braided structure comprises monofilaments each having a smoothly rounded outer surface of a large radius of curvature.  A protective layer may be provided between the tubular body and the braided structure or a filler such as an incompressible fluid substance having no constant shape is provided in the tubular body, or diameters of both ends of the braided structure and braided angles at both the ends are made larger than those at a substantially mid portion of the braided structure.  The actuator according to the invention decreases damage of the tubular body to elongate its service life and exhibits an improved contacting performance and high fatigue strength and can greatly save air consumption to eliminate the disadvantage of much air consumption of the air-bag type actuator without adversely affecting its advantages.
