Abstract: ABSTRACT OF THE DISCLOSURE A fluid-spray discharge apparatus has a housing associated with a fluid inlet. Also associated in a fluid outlet and an arrangement for effecting pulsation of fluid delivered from the inlet to the outlet. The outlet is composed of a series of spaced-apart fluid conveyances. Associated with the housing are means for enabling selection of the number of the series of conveyances operative in the flow of the fluid. Also included is an arrangement of fluid dischargers disposed outwardly of the conveyances and fluid emitters disposed inwardly of the same. Internal diverters and channels enable the provision of fluid delivery from any of the combinations of entirely from the emitters, entirely from the dischargers, in a mixture from the emitters and the dischargers, entirely from the conveyances and in a mixture from the dischargers and the conveyances.

Abstract: ABSTRACT             A method of affecting the tail end of a roll of plastic film to render it readily identifiable and easy to grasp and start without tearing the film web into strips. The tail end of the film is puckered, shrunk, or otherwise embossed on-line as it is separated and about to be wound up on a roll core.  The method is accomplished by securing the tail end between a heated surface on the upstream side of a knife on a cut-off roll and a lifting mechanism to provide a wide puckered, shrunken, or embossed portion across the tail end of the film at about the time it is severed from the film stock.  The method produces a novel puckered tail, particu-larly for highly oriented films where tension is relieved while the tail end is still heated.   18,476-F     18,476-F

Abstract: Abstract of the Disclosure An easily assembled and disassembled die holder assembly of the wedge locking type is provided which tightly clamps a punch die in its pocket. A die-engaging wedge of the assembly has an angular protrusion bearing on a wall of a corresponding groove in a side of the die to clamp it downwardly in the die pocket upon take-up of a threaded fastener. A locking wedge acted on by the fastener bears on the die wedge, relative angles of the latter and the protrusion causing the protrusion to hold the die rigidly. Backing off the fastener permits a resilient member to free the die from the protrusion of the die-engaging wedge.

Abstract: Abstract of the Disclosure A test reagent for HBsAg is prepared by applying to a suitable substrate, such as a polystyrene bead, a first coat of purified HBsAg to an extent which will permit complete coverage by anti-HBs. After washing the HBsAg coated substrate serum containing anti-HBs, or an IgG fraction of serum containing anti-HBs, is applied as a second coat in an amount which substantially occupies the reacting groups of the HBsAg of the outside of the substrate and leaves an excess of antibody reacting groups in a free state, and any unattached material is washed off.   A test sample which is to be tested for HBsAg is contacted with the reagent thus produced permitting attachment of HBsAg if present, and washing is done.  Then a source of anti-HBs, such as an IgG fraction containing anti-HBs, which has been radio-actively labeled, is brought into contact with the reagent and any unattached material is washed off.  The presence or absence of HBsAg in the test sample is determined from the presence or absence of significant additional radiation coming from the reagent as compared with a control.      This method and its double coated test reagent permits securing high sensitivity without any manufacture of "dissociated" anti-HBs separately from the process itself, for use at any stage of the process, which separate manufacture of "dissociated" anti-HBs is a difficult and expensive procedure which adds greatly to the expense of any radioimmunoassay which calls for it to be done.

Abstract: AIRCRAFT PARCEL-PICKUP MECHANISM ABSTRACT       This aircraft parcel-pickup device provides for the pickup of a parcel on the ground by an aircraft in flight.  A power unit is provided to pay out parcel-pickup cords from first sheave and to tension a first spring cord reeving onto a second sheave, the two sheaves being connected together and one reeving on spring cord while the other is reeving off parcel-pickup cord.  A manually operable pawl and ratchet is provided to prevent the parcel-pickup cords from reeving in, after being selectively extended, to facilitate engaging the parcel by a hook carried by parcel-pickup cords.  After such engagement, the resilient first spring cord compensates for the shock of contact between moving and nonmoving members and thereafter draws the parcel-pickup cord and the parcel to the aircraft.  The spring cord is provided with a governor to limit the speed of travel of the parcel as it nears the aircraft.  The governor is powered in one direction of travel by connections with the returning parcel-pickup cord and during such travel a second spring cord is being tensioned and powers the governor in its travel in the opposite direction.  The parcel-pickup cord is constructed to bend forward and to resist bending in the opposite direction.

Abstract: Case No. 4241.27 POWER FAILURE DETECTION AND RESTART SYSTEM            Abstract of the Disclosure A power failure detection and restart system for use with a microprocessor (microcomputer) control system includes first and second cascaded voltage comparators, the first of which responds to a drop in the supply voltage supplied to the microprocessor to produce an output pulse causing a software freeze of the microprocessor.  The microprocessor operates in response to the software freeze pulse to transfer the contents of certain registers thereof to a battery protected memory for temporary storage therein.  A positive feed-back circuit is used on the first voltage comparator to insure its rapid and complete change of state; and this change of state signal is applied through a time delay circuit to the second voltage comparator, which produces an output signal a predetermined time after the software freeze pulse is obtained from the first voltage comparator to reset the microprocessor to an initial circuit condition.  Built in hysteresis in the system is employed; so that when the power once again rises above the level sufficient to properly operate the system, the first and second voltage comparators are turned on in the same sequence they were turned off to re-establish operation of the micro-processor which picks up its routine at the point the interruption took place.
