Abstract: OUTSIDE WALLBOARD CORNER CONSTRUCTION AND               EDGING MEMBER FOR SAID CORNERS            ABSTRACT OF THE DISCLOSURE:         An outside longitudinal corner construction of wallboard panels includes a framing member of the rectangular wooden stud or C-shaped sheet metal channel type, an edging member which is essentially T-shaped in cross-section or of modified T shape and a pair of wallboard panels fitted to the edging member and held to the framing member in such a way that a flap of covering fabric or sheet, as of a pre-finished wallboard panel, or a part of the cover paper of such a panel, which cover material had had the wallboard core and back removed from it, is wrapped around the edging member T cross-bar and held in position by the other wall-board panel.  Thus, the edging member is concealed by the cover material, which is wrapped around it, and the corner construction matches in appearance the rest of the wallboard, with only one discontinuity along the length of the corner on one side thereof, and such is not conspicuous.  Also described are edging members incorporating various improve-ments, such as auxiliary cross-bars, grooves, aligning pro-jections and openings, wallboard holding means adapted to hold wallboards of different thicknesses, a rounded edge on one side of the T cross-bar and a sharper edge on the other side, and pre-deposited adhesive.  Procedures for construct-ing the corners are also disclosed.

Abstract: ABSTRACT         The particle sensing field of an electrical analyzer is focused by use of pairs of electrodes positioned across the path of particle flow.  The electrodes are oriented and/or energized so that their electrical fields bulge outward in the direction of the sensing field to narrow the width of the sensing field along the predetermined path.  The electrode arrangements can be implemented in a flow cell, with or without a sensing aperture, or on the surface of a substrate.

Abstract: COLLISION AVOIDANCE CIRCUIT FOR PACKET     SWITCHED COMMUNICATION SYSTEM            Abstract The efficiency of packet switching networks is improved by using a collision avoidance technique rather than collision detection.  The subscriber links are connected to a common node.  A collision avoidance circuit in each link monitors the node to determine whether it is in a busy or idle status.  The first message to arrive places the node in a busy status at which time all other, nontransmitting links are disconnected, thereby avoiding a collision.  Later arriving messages are stored in buffers at each subscriber location and are transmitted when the node is again idle.  In this manner messages are transmitted on a first-come basis, and can be of arbitrary duration regardless of bit rate.

Abstract: ELECTROGRAPHIC SYSTEM AND METHOD     ABSTRACT OF THE DISCLOSURE   An electrographic system utilizing u singular resistive layer which may be transparent in conjunction with a supportive substrate. Through the use of an electromagnetic field generating stylus in conjunction with coordinate alternating border switching, linear output performance is achieved. With the utilization ofsum, difference and divider circuitry in conjunction with received output signals, the system remains immune from voltage variations occasioned in conjunction with thestylus and, thus, the stylus may be operated in varying spaced-relationship from the resistive surface.

Abstract: MAGNETIC BRUSH DEVELOPER APPARATUS AND METHOD                  ABSTRACT Magnetic brush developer apparatus which alleviates any developer material starvation in the area of contact with a charge pattern-bearing member.  Such apparatus develops an electrostatic charge pattern on a member by contacting the member with developer material, including magnetic particles, transported toward and away from the charge pattern-bearing member by an applicator member.  The transported developer material is magnetically agitated in the area of contact with the charge pattern-bearing member in a direction which includes at least a component perpendicular to the transport direction, whereby intermixing of the developer material in such contact area is substantially improved to reduce any propensity toward toner starvation and the developed image defects resulting from such starvation.

Abstract: ABSTRACT (Fig 2) An optical transducer for detecting the position of a rotary or translatory member comprises a light source, a photodetector group (37) and a shutter (25) provided with a series of transparent elements (28) spaced by opaque regions (29) and interposed between the light source and the photodetector group. The latter comprises an integrated circuit, on a surface of which are disposed numerous photovoltaic cells (37) each being of an area which is a fraction of the area of each transparent element (28).  The cells are divided into four groups to generate as many electrical signals which are out of phase relative to each other by 90° and which are indicative of the position of the shutter with respect to the position of the photodetector group and the light source.  The cells (37) are disposed symmetrically with respect to a central optical axis (40), and in such a way that the barycentre of illumination of each of the four groups is coincident with that optical axis.  The sum of the four electrical signals is also used as feedback for control of the power supply for the light source.

Abstract: DISK MOUNTING MECHANISM Abstract of the Disclosure An arrangement for mounting a disk on a rotatable hub has a raised portion at the center of the hub for receiving a slot of similar shape and slightly larger size at the center of the disk and an elongated handle mounted on and having a cross-sectional shape similar to that of the raised portion.  The handle which is rotatably and slidably disposed on a shaft mounted on the raised portion is movable along the shaft in a direction away from the raised portion against the resistance of a coil spring encircling the shaft and residing between the elongated handle and a keeper at the end of the shaft opposite the raised portion.  With the disk mounted on the hub so as to position the raised portion of the hub within the slot, rotation of the elongated handle causes opposite portions of the handle to engage and ride up on an opposite pair of partially circular camming ramps having heights which gradually increase along the lengths of the ramps.  The handle is rotated until the opposite portions of the handle encounter and become seated within opposite detents within the tops of the camming ramps.  Removal of the disk from the hub is accomplished by turning the handle to unseat the opposite portions thereof from the detents and allow them to ride down the opposite camming ramps to the slot, whereupon the disk can be lifted off of the hub.

Abstract: ADJUSTABLE LENGTH PROSTHETIC JOINT IMPLANT      ABSTRACT           There is disclosed a surgically implantable prosthetic joint implant adapted for length adjustment after initial surgery to compensate, for example, for growth of a juvenile patient.  A stem (11) for bone implantation has a flange (12) for overlying the bone end and a threaded portion (13) for adjusting axially with respect to an overlying sleeve (14) which carries at its extremity an articulating component (16) of the joint.  A pin in the sleeve (18) and elongated slot (19) in the stem restrain relative rotation but allow axial relative movement as the stem is urged into or out of the sleeve by rotation of a nut (21) coacting with the threads on the stem while being axially restrained by the sleeve.  The nut is described as having a ring of gear teeth (26) to be actuated by an insertable gear-carrying key (27).

These particles are formed by various sol gel techniques, one example of which is the chemical gelation of titania sols by first mixing with glacial acetic acid, then with ammonium acetate, followed by formation of microspheres in 2-ethylhexanol.  Microspheres of this ceramic composition can have relatively large diameters (e.g. over 200-1000 micrometers) making them quite useful as retroreflective lens elements in pavement marking sheet materials.
