Abstract: IMPROVEMENT IN POSITIONING JOINT FOR FOLDING LADDERS     ABSTRACT    A joint having two joint members which are pivotable with respect to each other about a common axis is lockable in a series of predetermined angular positions by engaging a spring-biased pawl provided within one member in notches formed at the peripheral edge of the other member.  In manually operating the joint, the forked release element and the handle pivotably connected with each other act as an operating lever in cooperation with the clawed, spring-loaded control means in controlling locking and unlocking of the joint.  The claw like stop portion of the control means, when being pushed to one side within the slot  having its length at least twice longer than the width of the notch by the release element in counter-clockwise direction, permits engagement of the pawl in the notches and, upon operation of the handle thereby dis-engaging the pawl from the notches, returns to rest position under its spring force in clockwise direction.  In this position, the stop portion, by pressing against the back of the release element in blocking the pawl from falling back to the notches, effectively prevents engagement of the pawl in the notches to permit free pivoting of the joint.    Reference is given here to applicant's prior U.S. application with Serial No. 532,096  , filing date September 14, 1983.

Abstract: TITLE              AN ORGANIC P-N JUNCTION      WITH ANTENNA                           INVENTORS                        James R  BOLTON and James Edwin GUILLET                    ABSTRACT     An organic P-N junction preferably made of a porphyrin interlined with a quinone at a distance of between 10 .ANG. and 40 .ANG. is known in the art and although its theoretical efficiency is 16% to 18%, its actual efficiency is about 1% due to the inefficiency in the absorption of light at the molecule sur-face.  The absorption of light can be increased from 1% to al-most 100% and the theoretical efficiency therefore of the P-N junction can be increased from approximately 1% to the theore-tical limit of 16% to 18% by disposing upon the P-N junction material an antenna comprising a polymer disposing therein sensitizers preferably organic dyes which absorb light and cause the light to be cascadingly transferred through the polymer and deposited at the surface of the donor region of the P-N junction where the light is then absorbed and the P-N junction liberates an electron.  Preferred dyes which act as sensitizers and are appropriately light transmissive and elec-tron conductive are polymers including naphthalene anthracene and phenanthrene.

Abstract: ABSTRACT           Bulk cargo which is sensitive to condensate is confined in the cargo area of a seagoing or other vessel in such a way that it comes into direct contact with the walls surrounding the cargo area and is also in contact with moisture-laden air filling the remainder of such area.  In order to prevent condensation of moisture on the walls surrounding the cargo area, the temperature of the walls as well as the temperature of air in the cargo area is maintained at a value such that the moisture cannot condense on the walls.  This can be achieved by heating the confined air and/or the walls and/or by reducing the moisture content of confined air and/or by a combination of such undertakings.

Abstract: Title:    "FEEDERS FOR HEADED FASTENERS"                   ABSTRACT          A feeder for headed fasteners, such as rivets (43), driven at equal intervals through a tape (44), is applicable to a riveting machine (10) and includes a plunger (25) advanced and retracted through a guide bush and with a punch (37) at its leading end.  When the plunger (25) advances the punch (37) is driven through a delivery passage in the guide bush (39).  A guide passage (45) leads the tape (44) to bring fasteners (43) in sequence into the delivery passage. An actuator (56), oscillatable in the guide bush (39), is moved to retracted position by the advancing plunger (25), and is automatically returned to advanced position when the plunger (25) retracts.  Fastener engaging means (64) on the actuator (56) act, with each retraction and advance of the actuator (56), to engage a fastener (43) and move it towards the delivery passage from which the leading fastener (43) is driven by the advancing punch (37) which, penetrating the tape (44) holds the tape (44) against movement while the actuator (56) is moved to its retracted position.

The chip material is augered in a forward direction in a monitored flow longitudinally away from the bin while pass-ing it across a first stationary screen trough system having openings of a size to pass everything, while rejecting the overs.  The acceptable chips and fines passed through the first screen trough system are then augered across a second stationary screen trough system having openings of a size to pass the fines to a fines trough, while retaining the acceptable chips. Finally, the acceptable chips are moved forwardly toward a chip discharge location while the fines passed through the second screen trough system are separately collected.  The system includes mechanism for diverting chip-ped material unsuited to use in a paper mill, such as chipped tree tops, directly to the fines trough.

Abstract: ABSTRACT OF THE DISCLOSURE     A cordless telephone having a base unit and a separate handset unit is operable in an intercom mode in which operators at the two units are in telephonic communication.  If an incoming telephone call appears when the telephone is in the intercom mode, the loudspeaker of the handset unit and a ringer of the base unit both produce a ringing sound to announce the call.  When one unit is then disabled by the operator thereof hanging up, the other unit is automatically connected to the telephone network line to receive the incoming call.  The handset unit produces the ringing sound from its loudspeaker at a first volume when it is disabled and in a standby mode, and at a second lesser volume when it is enabled and in the intercom mode to avoid producing a loud ringing sound directly into the ear of the handset operator.

Abstract: ABSTRACT OF THE DISCLOSURE        A diffuser for dispersing gas into a body of liquid that may contain suspended solids.  Under ordinary clogging conditions, the diffuser will remain operative over an indefinite period of time by reason of large gas outlet openings at the bottom of the gas plenum chamber.  In addition, it can be employed for a good portion of that time to dis-perse a substantial flow of coarse bubbles and fine bubbles, in a desired combination, simultaneously from a single gas plenum.  Careful selection of the permeability of a top porous wall of a gas plenum chamber, together with proper selection of the level of coarse bubble gas outlet openings in the side walls of the plenum chamber achieve the second feature.
