Title: Helicopter cargo hook
Inventor: SMITH DONALD E
IPC: B66C1/34
Filed: 1987-03-13
Granted: 1991-03-26
Abstract: ABSTRACT OF THE DISCLOSURE     A releasable self-resetting cargo hook for heli-copters and other aircraft for supporting suspended loads. The cargo hook apparatus includes a pivotally supported load arm maintained in its load supporting condition by a pivotally mounted latch arm whose posi-tion, in turn, is controlled by a pivotally mounted latch.  The position of the latch is determined by a pivotally mounted lock arm lever whose normal position is determined by a stop pin and which is operated by a release mechanism.  The interconnection between the latch and lock arm lever is through a cam slot defined on the latch receiving a lock arm lever follower, and the cam slot-follower relationship prevents impact forces imposed on the cargo hook structure from inadver-tently producing lock arm lever rotation and latch move-ment.

Title: Sheet diverter and delivery system
Inventor: LITTLETON FRANCIS J
IPC: B65H29/58
Filed: 1987-04-03
Granted: 1991-10-22
Abstract: ABSTRACT OF THE DISCLOSURE           An apparatus for diverting and delivering sheets in which the sheets are positively controlled throughout the entire operation.  Initially, a continuous web of paper passes between opposing cylinders comprising a rotary cutter.  The lead edge of the web is then engaged by a pair of opposed nip rollers.  Once held by these nip rollers, the rotary knife cuts a separate sheet from the front of the continuous web.  The separate sheet then passes between and is accelerated by the nip rollers whereupon a dual set of diverting cams, in combination with a pair of conveyors, directs the sheet to one of two delivery systems.  The next subsequent sheet is directed to the other delivery system so that each successive sheet is alternately diverted between the two delivery systems.          Upon entering either delivery system, the sheet is subjected to a snubbing means which decelerates the sheet and further allows the next subsequent sheet to overlap the previous sheet before being similarly decelerated.          The shingled sheets are then transmitted by conveyor to a subsequent handling operation.

Abstract: RCA 83,439 ABSTRACT OF THE DISCLOSURE A signal suppression component such as a ferrite shield bead includes a cylindrical magnetically permeable member that has a longitudinal passage formed through it. The passage is filled with an elastic silicone rubber material.  When the component is placed on a conductor or component lead, the elastic material forms a damping layer between the conductor and the permeable member to prevent audible vibration of the element due to current flow in the conductor.  Such a component is especially useful in a line rate deflection circuit and in a resonant retrace power supply circuit.

Title: Line receiver
Inventor: CHU JOHN W
IPC: H03F3/45
Filed: 1987-12-23
Granted: 1991-01-08
Abstract: Abstract of the Disclosure An improved line receiver with high common mode rejection is operable at voltages above the power supply voltage (VCG) as well as below ground.  Input resistors provide high input impedence as well as means through which current summing of current mirror currents at the input transistor base nodes is translated into voltage drops which boosts the common mode rejection range of the circuit.          Built-in hysteresis circuitry ensures proper detection of non-common mode signals.  The high input impedence and high sensitivity allow multiple receivers of the type to be connected in parallel across a common bus for interrogation by a remote system.  The preferred embodiment of the present invention is implemented in integrated circuit technology.

Title: Power supply for discharge machining apparatus
Inventor: FUTAMURA SHOJI
IPC: B23H1/02
Filed: 1988-01-13
Granted: 1991-09-24
Abstract: ABSTRACT OF THE DISCLOSURE  A  discharge  machining  apparatus adapted  to  quickly absorb  the energy,  which has been accumulated by an  in-ductance component during discharge machining,  during the non-discharge period.   The accumulated energy is absorbed as  it  is caused to flow as a current  in  an  equivalent resistor having a resistance varying function.   With this invention,  it  becomes possible to increase the frequency of  discharges per unit time since the energy  is quickly absorbed  without residue as the change in the  resistance value  of the equivalent resistor causes the current flow-ing  in it to shift from an oscillating state to a  normal damping state.

Granted: 1992-01-14
Abstract: COMPUTER METHOD FOR AUTOMATIC EXTRACTION OF COMMONLY SPECIFIED INFORMATION FROM BUSINESS CORRESPONDENCE                        Abstract A Parametric Information Extraction (PIE) system has been developed to identify automatically commonly specified information such as author, date, recipient, address, subject statement, etc. from documents in free format.  The program-generated data can be used directly or can be supplemented manually to provide automatic indexing or indexing aid, respectively.     The PIE system uses structural, syntactic, and semantic knowledge to accomplish its objective.  The structural analysis identifies the major components of a document which are the document heading, body, and ending.  The heading and the ending which usually contain commonly specified information, are then analyzed by a battery of morphological, syntactic, and semantic pattern-matching procedures that provide specified information in standardized forms that can be easily manipulated by computer.

Granted: 1992-12-29
Abstract: ABSTRACT   A system for the control and conveyance of particulate material from a standpipe to the furnace of a circulating fluidized bed boiler. Aeration means positioned in a first area of a conduit transports particulate material deposited by a standpipe to a second area of the conduit. Upon such relocation, additional material from the standpipe enters the first area of the conduit as a replacement for the previously removed material. Fluidizing means in the second area of the conduit fluidizes this removed material causing it to achieve a generally uniform level within this second area. As the height of this level exceeds that of the lower edge of a discharge opening, the fluidized material passes through this opening and into the furnace of a circulating fluidized bed boiler.
