Abstract: STERILE SOLUTION CONTAINER            Abstract of the Disclosure A tamperproof sterile solution closure system which will permit the machine assembly of the closure cap to the container without engagement of the threads of the cap with the container threads.  The screw type cap member has internal threading, a tear-away portion and a skirt portion.  The container has an abutment surface for sealable contact with the skirt portion and in a position such that the threads in the cap and on the neck are not engaged.  To activate the closure, a tear-away portion is removed which will allow the threads to engage.  Simultaneously, a contact portion on the cap will engage a weakened flange in the neck to cause it to be separated.  A projection extending from the cap is positioned in an annular recess in the cap to serve as a captive means for the separated dome portion of the cap for replacement purposes.

Abstract: TERMINAL ADDRESS ASSIGNMENT IN A BROADCAST TRANSMISSION SYSTEM     Abstract of the Disclosure In a broadcast transmission system, in which in normal operation messages and terminal addresses are transmitted between a master station and a plurality of terminals each having an assigned address, the master station initially assigns the addresses to the terminals.  In order to isolate each terminal in turn to assign it an address, the master station varies one or more parameters which affect the bit error rate of the terminals while polling the terminals, and each terminal which receives the poll with an acceptable bit error rate responds to the poll.  When the master station receives only one response to a poll, it assigns an address to the responding, isolated, terminal which thereafter does not respond to the poll.  This procedure is repeated until addresses have been assigned to all of the terminals.  The parameter may, in particular, be the strength of the signal transmitted by the master station.                                         - i -

Abstract: MICROTOME HAVING SPECIMEN RETRACTION MEANS          ABSTRACT OF THE DISCLOSURE    A microtome provided with a drive wheel mounted in a stand, to be actuated manually and/or by means of a drive motor for generating a vertical relative movement between a specimen holder and a cutting knifer  has a specimen holder, having a specimen clamping mechanism, arranged so as to be horizontally displaceable in a vertically driv-able guide mechanism by means of a cutting-thickness ad-justment mechanism.   The adjustment mechanism can hori-zontally displace the specimen holder through a cutting thickness adjustment distance towards the cutting knife.          A specimen retraction mechanism serves to displace hori-zontally the specimen holder from an unretracted position to a retracted position,  the  retracted position being further  from  the  cutting  knife than  the  unretracted position.   The distance between the retracted position and the unretracted position is greater than the maximum cutting thickness adjustment distance.

Abstract: ABSTRACT OF THE DISCLOSURE           A crop chopper has a main housing generally extending along an axis and having an outwardly open intake and a radially outwardly open outlet angularly spaced therefrom, a main chopping rotor having a plurality of angularly spaced blades and a plurality of angularly spaced wind vanes and rotatable about the axis in the housing in a predetermined rotational sense to displace the blades in an orbit, and a drive that rotates the main chopping  rotor  in  the  rotational  sense  for coarsely cutting the crop at the intake,  for displacing the cut crop in the rotational sense back in the main housing, and for propelling the cut crop radially outward through the outlet.  A supplementary housing opens radially into the main housing downstream in the sense from the intake and upstream from the outlet.  Thus the coarsely cut crop is displaced by the main cutting rotor into the supplementary housing. A  supplementary  chopper  rotatable  in  the supplementary housing  outside  the  orbit  has  radially extending cutting formations.  This supplementary chopper in  the  supplementary  housing  is  rotated  to  finely comminute the coarsely cut crop therein and to reintroduce the finely comminuted crop back into the main housing upstream of the outlet.

Abstract: BAND SAW APPARATUS AND METHOD              by GERALD R. HARRIS     ABSTRACT         Band saw apparatus (21) is disclosed.  It includes: a drive assembly (22, 27, 28) formed for support and guided movement of a saw blade (29) for cutting of a workpiece (81); an endless band saw blade (29) mounted to the drive assembly; and, reciprocation apparatus (33, 34, 41) formed for reciprocation of the blade (29) toward and away away from the workpiece (81) to enable see-sawing of the blade (29) and variation of the force per unit area of the cutting edge (66) of the blade (29) on the workpiece (81) while maintaining the same total force on the blade (29).  To enhance efficiency of  cutting, the blade drive assembly is mounted to the remainder of the saw (21) to be substantially free to rebound or move away from the workpiece (813 during reciprocation to avoid digging in or shearing off of the blade teeth and to permit close spacing of the blade guides (33, 34) next to the workpiece (81). The saw (21) includes a control circuit (111, 154) for controlling the rate of movement of the saw arm (22) away from (36) and toward (37) the workpiece (81) to enable timing of saw arm (22) rebound to blade (29) displacement. The blade guides (33, 34) are reciprocated by the fluid piston-cylinder assemblies (41) in synchronism or out-of-phase to vary the amplitude, frequency, speed and dwell during displacement independently of blade (29) speed and at two locations along a length of the blade (29) so as to produce see-sawing oscillation as well as simple reciprocation.  The blade guide assemblies (33, 34) are provided with displacement means (41) to permit guide assembly (33, 34) adjustment during cutting to maintain the guide assemblies (33, 34) in close proximity to the workpiece (81).  Alternative blade displacement assembly constructions and a method for cutting workpieces employing the apparatus also are disclosed.  The method includes variation of the feed rate of the saw blade (29) down through the workpiece (81) as a function of the width of the workpiece (81).

The dielectric layers form a composite structure having different refractive indices for light of different polarizations.          The differing refractive indices cause the polarization states of light guided by the fiber to be non-degenerate so that energy ordinarily will not couple from one polarization to the other.  The fiber includes a cladding that may have a refractive index energy less than both core indices to provide a polarization maintaining fiber or greater than or equal to one of the core indices to provide a polarizing fiber.  The method of fabrication of the layered core form birefringent optical fiber includes forming a structure of a plurality of layers of the dielectrics, heating the structure to form a monolith, stretching the monolith to form the fiber core, and adding the cladding to the core.

Abstract: ABSTRACT     Certain, but not all AM stereo radio broadcasting and reception systems suffer from a severe form of reception anomaly wherein the perceived stereo image moves from side to side, back and forth, which effect has come to be known as "Stereo Platform Motion" or simply "Platform Motion".  A prior art patent proposed a method far sensing reception conditions conductive to Platform Motion and then switching the receiver from stereo to monophonic reception to avoid Platform Motion.  The present invention enables the AM stereo receiver to maintain stereo operation under such reception conditions, and instead of switching the receiver to monophonic operation, it switches the receiver to a different method of stereo reception that does not suffer from Platform Motion.
