Abstract: A T-S-T-S-T DIGITAL SWITCHING NETWORK      ABSTRACT OF THE DISCLOSURE A time-space-time-space-time switching network is composed of a subscriber connected to a remote unit network having a time and space switching stage.  The subscriber is then connected to a central office switching system having a time-space-time switching network.  Alternatively, the switching network may comprise a subscriber locally connected through the time-space-time switching network of the central office switching system to the space and time stages of the remote switching unit.  The remote unit network and the central office network are intercon-nected by a number of digital spans.  In addition, the remote unit and the central office each provide for local to local traffic.  That is, traffic which is transmitted only within its own switching network.

Abstract: ABSTRACT            A drilling boom is pivoted about a first axis on a base and is pivoted about that axis by a first hydraulic cylinder.  It carries a feeder beam carrier at its forward end.  The carrier is pivoted at the forward end of the boom about a second axis which is parallel to the first axis, and it is moved about the second axis by a second hydraulic cylinder in a sense opposite to that in which the boom is moved by the first cylinder.  The first and second cylinder are so dimensioned and hydraulically interconnected that fluid which is expelled from the first cylinder actuates the second cylinder and vice versa.  The angular movements of the boom and carrier are equal in magnitude.

Abstract: Abstract Head & Method for Orienting Electrical Components In known pick-up heads for orienting electrical components the component, supported by a pick-up tool, is engaged by a plurality of pairs of opposed jaws to urge the component into a desired orientation. When the components become oriented, the pairs of jaws exert a slight gripping force on the component which can damage fragile components, for example so-called "chips".  In the invention, a datum face of the pick-up tool against which the component is supported has the same peripheral shape as the component but each dimension is slightly larger than the corresponding dimension of the component and orienting faces of the jaws are disposed to engage the periphery of the pick-up tool when the component is oriented so that the components are not gripped between the pairs of jaws.  Likelihood of damage is thus reduced.

Abstract: RECOVERY OF ALEURONE CELLS FROM WHEAT BRAN                 ABSTRACT OF THE DISCLOSURE            A method for the physical separation of aleurone cell particles and pericarp-testa particles from commercial wheat bran is provided, which method comprises removing from a fraction of aleurone cell particles and pericarp-testa particles within the sieve mesh range of larger than about 130µm and smaller than about 290µm, obtained from commercial wheat bran by subjecting the bran to hammer-milling whereby the bran is broken and reduced into particles which consist predominantly of pericarp-testa particles and aleurone cell particles and then sized to said sieve mesh range, a fraction of particles which are smaller than about 40µm and electrostatically charging the remaining aleurone cell particles and pericarp-testa particles, then passing said electrostatically charged remaining aleurone cell particles and pericarp-testa particles through an electrical field generated by an electrostatic separator, whereby the remaining aleurone cell particles and pericarp-testa particles are fractionated by the differential of their electrical charges.  Removal of said fraction of particles which are smaller than about 40µm and the electrostatic charging of the remaining aleurone cell particles and pericarp-testa particles is preferably effected by air elutriation of the mixture of said particles. and which induces triboelectrification of said particles.

Abstract: ABSTRACT OF THE DISCLOSURE A foundry molding machine is provided with a pattern plate (86) surrounded by and movable in a well form (87). In a preferred form springs (105, 106) bias the well form upwardly around the pattern plate to form a well. The pattern plate and well form are mounted on a squeeze table (31) and cooperate with the underside of a conventional flask which in turn engages an upset (53) to form a mold chamber for receiving molding sand. In such preferred form the sand is blown under very low pressure into the chamber through a slotted squeeze head (47). As the squeeze table moves upwardly, sand is initially squeezed from the top against the squeeze head while the flask, upset, well form and pattern plate move upwardly as a unit. When a selected level of the flask is reached, preferably when the top is flush with the squeeze head, upward movement of the upset is stopped while the table continues upwardly. The pattern plate then telescopes upwardly within the well form while the flask and well form are held fixed. This compresses the springs supporting the well form. The squeeze continues with the sand being compressed both from the squeeze head and from the pattern plate concurrently until the pattern plate is just even with or slightly below the bottom of the flask. At such time, the table moves down for draw as the springs extend and to permit the mold to clear the machine. Other forms of the present invention provide embodiments utilizing a dump-fill (155) of the flask in combination with an equalizing cylinder squeeze head (156). In yet another embodiment, the well form may be mounted by a piston-cylinder assembly (221-222) for movement independently of the pattern plate thus enabling the depth of the well to be adjusted between cycles.

Abstract: III.  ABSTRACT An air dispensed assembly in the form of a submunition cannister is disclosed which has the capability to perform a lateral maneuver during the  final  1500 ft.  of descent before  impact.   Maneuvering is accomplished by deploying a  samara blade  shaped wing  from the  rear  of the submunition cannister after ejection from the casing of the launching shell.  The wing is sized and provided with an angle of attack which causes the cylindrical shaped cannister to spin as it descends downward at approximately a constant rate of descent.   A passive infrared sensor  in the nose  of the cannister provides  target  information  to  a  data  processor  which  generates  steering commands to appropriately alter the wing angle of attack so as to bring about a corrective lateral change in direction.   When within lethal range of the sensed target, the warhead in the submunition is detonated.
