Abstract: ABSTRACT OF THE DISCLOSURE Cold ammonia, preferably cold liquid anhydrous ammonia at substantially ambient or atmospheric is applied (1) to soil as a fertilizer and (2) to feed grains, forages and anaeroblically fermentable plant material to supply thereto and provide therein non-protein nitrogen (NPN).  The cold ammonia is obtained by (1) introducing a stream of ambient temperature, pressureized liquid ammonia at a velocity of at least about 5000 feet per minute into an expansion chamber, (2) inparing a high velocity spinning motion to the liquid ammonia entering the chamber such that rapid flow is produced around the interior of the chamber to thereby provide rapid separation of the liquid and gaseous ammonia formed in the chamber.  Cold ammonia, which is predominantly in the liquid form, is recovered from the expansion chamber operated under substantially adiabatic conditions, at a temperature of about -28° F.

Abstract: ABSTRACT OF THE DISCLOSURE         A verification method and system for determining whether a holder of a card is authorized to complete a transaction through an on-line terminal of an institution in a network of cooperating institutions, such as banks.  The method and system are also useable in such applications as accessing a security data file in a compu-ter, entering a security area, completing a point of sale transac-tion and operating on-line automated tellers in banks.  In the pre-ferred embodiment, the card contains information including first data identifying the institution holding an account of an author-ized card holder and second data identifying the account.  The first and second data are machine read from the card and a secret number, derived from the data but known only to the authorized holder of the card, is keyboard entered by the card holder.  The first data are used to address a read only memory having random characters stored therein.  Random character digits outputted from the memory are successively exclusive ORed with each digit of the second data and the resultant applied to the address terminals of the memory to cause pseudo-random vectoring among random data stored in the memory. Preselected digits of the characters generated by the memory are correlated to the digits of the secret number to generate a go-no go indication of whether the holder of the card is authorized to transact in the system.  By the provision of an offset number on the card, all digits of the secret number can be selected by the holder of the card when the card is issued.  The offset number con-verts the secret number digits selected by the card holder to di-gits which correspond to the preselected digits of the memory gen-erated character.  She card can be verified at any institution of a network of cooperating institutions having verification systems with identically programmed read only memories.  The first data contained on the card cause the transaction to be charged against the institution holding the account and prevent comingling of trans-action records among the cooperating institutions.

Abstract: ABSTRACT         Apparatus for applying a tubular insulating housing to an electrical connector crimped to a wire comprises a horizontal base at one end of which are disposed a pair of wire gripping jaws, one of which is fixed to the base and the other of which is movable by a plunger vertically towards and away from the base.  A support having a channel for receiving an electrical connector crimped to a wire is pivotally mounted on the base immediately rearwardly of the fixed jaw, a slide on the base being movable there along towards and away from the fixed jaw through a mechanism operated by the plunger.  The slide has at its forward end a recess opening towards the fixed jaw, for receiving a tubular insulating housing.  With the wire gripped between the jaws at a position just back from the connector, and with the connector located in the channel in the connector support, the slide is advanced from a position remote from the fixed jaw, to cause a housing in the recess of the slide to be pushed onto the connector to receive it, as the slide displaces the connector support about its pivot to eject the connector from the connector support whereafter the slide is retracted, the movable jaw is raised and the connector with the housing thereon is removed from the apparatus.

Abstract: ABSTRACT OF THE DISCLOSURE       The leading ends of a tongued web member and a pair of grooved chord members are moved longitudinally against stops, with the trailing ends of the chord members spread apart in divergent relation.  A pair of opposed piston presses the leading ends of the chord member toward the opposite side edges of the web member, forcing the tongues on the web member into the grooves of the chord members, which grooves have previously been coated with glue.  Then the stops and pistons are retracted and the three members, thus joined together at their leading ends, are advanced between a pair of rubber tired drive wheels, meanwhile allowing the divergent trailing ends of the chord members to swing toward each other as the members progress through the drive wheels. The drive wheels are power driven to feed the assembled beam through sizing rollers which progressively squeeze the chord members toward each other as may be necessary to produce a beam of predetermined width dimension.

Abstract: COMBINATION FAILSAFE BRAKE     AND ONE-WAY CLUTCH          Abstract of the Disclosure A combination fluid power disc brake and one-way clutch unit is offered.  An inner shaft is journalled in a stationary housing, and an outer shaft is journalled upon the inner shaft.  A one-way clutch between the shafts causes the inner and outer shafts to rotate together as a unit when the inner shaft is rotated in one direction, but permits the inner shaft to rotate independently of the outer shaft when the inner shaft is rotated in the opposite direction.  A disc brake assembly operates upon the outer shaft to selectively retard its rotation.  The disc brake assembly is of a fail-safe design, and permits outer shaft rotation when a positive hydraulic pressure is applied to the unit.  If pressure is lost or removed, the brake is activated, and outer shaft rotation is halted.
