Abstract: KEY HOLDER                    ABSTRACT       A key holder comprises an elongate, resilient member adapted to receive thereon a plurality of keys which have respective member receiving apertures in their heads.  The member is configured to provide a coiled intermediate portion and a pair of leg portions which extend therefrom at an acute angle.  The ends of the leg portions remote from the intermediate portion are configured to provide means for releasably clasping the leg portions together when the same are compressed toward each other by the hand of a user.  The overlying sections of the intermediate portion contact each other adjacent one leg portion and diverge from each other toward the other leg portion.  Sliding of a key from a segment of the intermediate portion is substantially inhibited without manual aid and a key can slide relatively freely on the overlying sections over a majority of their lengths.  This permits the user to isolate one key from the other keys so that the key can be more conveniently used.

Abstract: MAGNETIC CONTROL APPARATUS                      Abstract Magnetic control apparatus for intensifying a magnetic field to actuate a magnetic control member and for preventing simultaneous actuation of a pair of mag-netic control members.  In one of several embodiments a pair of selectively movable magnets each respectively produces a magnetic field which, when a magnet is moved into position, is directed by a pair of elongated bars across the pair of control members to actuate one of the members in response to the field.  The pair of bars bypass the magnetic fields from the control members when both magnets are in such a position to attempt to actuate the control members.  The pair of elongated bars intensify the magnetic fields in the control members, thereby permitting the use of relatively weak magnets at a substantial distance from the members. The pair of bars also provide a magnetic interlock, preventing undesirable simultaneous actuation of the members.  The apparatus can be used on a pedal of a fork lift truck to actuate one member to shift a trans-mission into forward drive and to actuate the other member to shift the transmission into reverse drive. Also disclosed is magnetic control apparatus to perform only the function of field intensification.

Abstract: ABSTRACT OF THE DISCLOSURE   A monorail suspended conveyor system for conveying materials long a curvilinear path has a plurality of tandemly disposed belt supporting carriages, each carriage having a framework which defines an open extent extending longitudinally therethrough and includes a upper elongated tubular link member and a lower pair of traversely spaced apart side members disposed on opposite sides of the open extent. Adjacent carriages are connected by an articulated joint suspended from the overhead rail and provides for universal movement of one carriage relative to another. The ends of adjacent side members are provided with cooperating structures to selectively limit the lateral swing of the carriages transversely with respect to the longitudinal movement thereof along the curvilinear path, thereby maintaining the conveying belt in a generally horizontal operating mode. The carriage train is moved along the monorail by two power units each having drive wheels disposed on opposite sides of the monorail. The power units are pivotally interconnected such that the power units can be pivoted relative to one another whereby the respective drive wheels are pivoted toward and away from one another so as to maintain a drive traction relationship with the overhead monorail. A rigid framework disposed in the proximity of the power units and suspended from the monorail is provided for transmitting movement force from the power units to the articulated conveyor. Each end of the power unit is connected to respective end portions of the framework by a flexible chain. When the power units and the conveyor along therewith is moved in one direction, one of the chains is put in tension so as to provide a force path through the rigid framework whereas the other chain is relaxed. Movement in the opposite direction puts the other chain in tension. The orbital conveying belt which includes a flexible chain attached to and extending longitudinally along the centerline of the belt is driven by a twin sprocket having alternating pitch teeth which drivable cooperates with the links of the chain so as to decrease the increase of tension in the belt as the same travels around the sprocket.

Abstract: PROCESS FOR PREPARING AROMA- AND FLAVOR-ENRICHED SOLUBLE COFFEE                    Judith A. Zaunbrecher and Richard G. Crooks Abstract A process for desorbing the volatile aroma and flavor components from roast and ground coffee having a particle size above about 1000 microns is disclosed.  The roast and ground coffee particles are mixed with water or ice in a ratio of 0.1 to 0.9 parts of water per part of coffee in a fluidized mechanical mixer.  The water/coffee mixture is then contacted with steam under vacuum (temperature of 32° to 125°F, about 5 to 100 mm mercury absolute pressure).   The resulting volatiles-laden steam is condensed, preferably in a two-stage operation.  The first condenser removes most of the water and a fraction of the volatiles at 32°-125"F, and the remaining volatiles are condensed in a cryogenically cooled trap, preferably at liquid nitrogen temperature.   The moisture level of the coffee during devolatilization is from 15% to 65% by weight.  The devolatilized roast and ground coffee can then be used in a conventional extraction column.  The draw-off ratio of extract to column charge is from about 2.3 to about 3.2.          This produces a coffee extract having from 13% to about 26% solids.   The extract and the coffee-volatiles condensates provide the components of an improved highly aromatic and flavorful instant coffee.
