Title: Attitude pointing error correction system and method for geosynchronous satellites
Inventor: AGRAWAL BRIJ NANDAN
IPC: B64G1/24
Filed: 1989-12-20
Granted: 1998-12-01
Abstract: A system and method for attitude control in a geosynchronous satellite (10) to compensate for roll and yaw pointing errors consequent to orbit inclination variation from the nominal equatorial orbit plane provides for an inertially fixed momentum vector coupled to the satellite (10) through a gimbal system (22) providing a one and preferably two degree-of-freedom relationship with the momentum vector.  In a two degree-of-freedom embodiment, the momentum vector is established by spinning the satellite (10) about an axis or providing an independent momentum wheel (54) with the gimbal axes provided along the roll and yaw axes.  Gimbal torquers (30,34) torque the satellite (10) about the inertially fixed momentum vector in a time-varying manner to effect correction of the roll and yaw pointing errors. Additionally, a conventional thruster (Tn) system is provided for pitch axis error correction and large orbit corrections attendant to the station-keeping function. Roll and yaw pointing errors consequent to orbit inclination drift from the nominal equatorial orbit are corrected in a fuel-efficient manner to extend the operating life of the satellite (10).

IPC: B65G61/00
Filed: 1991-02-07
Granted: 2001-04-17
Abstract: A system for remotely resetting a postage meter, by adding a variable amount of postage, includes a computerized central facility or "host", in telephone communication with the meter, which host verifies the meter's identity and ascertains the availability of funds, then sends to the meter an authorizing, unique, one-time-only combination, independent of the value of postage requested, and having a predetermined relation to a unique, one-time-only combination that the meter has generated and retained. The meter then compares the combination that it has generated with the combination received from the host. If the relationship is correct, for example, if the combination is the same, the meter introduces the additional postage requested.

Title: Retro-fittable extendable leg rest apparatus
Inventor: LAPOINTE LARRY P
IPC: A47C1/035
Filed: 1991-11-13
Granted: 1994-11-08
Abstract: A retro-fittable, controllably extendable leg rest apparatus for positioning an attached recliner chair leg rest member in retracted  or  forwardly  extended  positions.    The  apparatus includes an elongated frame bracket which may be retro-fittably secured to most conventional  scissor linkage assemblies of various recliners.  A mounting bracket is included having a first bracket portion secured to the leg rest member, and a second bracket portion having an elongated channel.   A plurality of rivets  extend through the  elongated  channel to  secure the mounting bracket to the elongated frame bracket.  The shanks of the rivets provide guide members upon which the elongated channel of the mounting bracket may slide.  A spring is coupled inbetween a shoulder portion of the mounting bracket and the elongated frame  bracket  to  bias  the mounting  bracket  in  a  normally retracted position.  A latching member is pivotally secured to a portion of the scissor linkage assembly to releasably latch the mounting bracket  in  the  forwardly extended position.   The apparatus is extended to the forwardly extended position by applying an outward force to the inner edge of the leg rest member when the scissor linkage is fully protracted, thereby causing the mounting bracket to slide along the shanks of the rivets until the latching member latches with a latching edge surface of the mounting bracket.   When the scissor linkage assembly is manually retracted, the latching member is urged out of engagement with the latching edge surface, thus enabling the spring to forcibly return the mounting bracket to and maintain it in the retracted position.

Abstract: A synthetic diamond wafer grown by deposition from a plasma has a smooth, substrate side face and a rough, deposition side face. The rough face is coated with a bonding agent which fills the valleys and is finished so that its surface is parallel to the substrate side face to permit photolithographic processing of the wafer. Also disclosed is a multi-wafer laminate of two or more diamond film layers bonded together with an interlayer. Smooth, flat outer faces of the layers are oriented mutually parallel. The inner, bonded faces may be rough. A filler of diamond particles in the bonding agent improves the thermal conductivity of the laminate.

Title: Double sided break open game ticket
Inventor: SANDERSON JOHN H
IPC: A63F3/06
Filed: 1992-04-21
Granted: 1995-05-09
Abstract: A break open game ticket comprises a first and second substrate laid back to back.  Each substrate includes an upper  half  which  includes  information  concerning  winning combinations of symbols and a lower half which includes three break open panels.   One substrate is inverted relative to the other substrate so that the panels of one are aligned with and overlie the information section of the other thus keeping the panels entirely separate.  The panels on one side can therefore be opened to expose the combinations printed on the backside of the  information area of  the other substrate.   The games are thus  independant  and provide  a novelty effect  improving  the pleasure of the game player.

Title: Deposition of tungsten
Inventor: EMESH ISMAIL T
IPC: C23C16/02
Filed: 1992-04-29
Granted: 1999-02-16
Abstract: A method is provided for low pressure chemical deposition of tungsten and tungsten metallization for defining interconnects for an integrated circuit.  A surface layer of tungsten is provided which has a low film stress and a smooth surface characterized by a low diffuse reflectivity and high specular reflectivity, to facilitate photo-lithography.  Tungsten is deposited by reduction of WF6 with H2 and SiH4 in nitrogen.  Control of the gas flow rates, pressure, temperature and H2/WF6 ratio in the reactive gas mixture provides for tailoring of the structure and characteristics of a deposited tungsten layer to provide high step coverage or a smooth surface for forming an overlying layer of tungsten which may be patterned photo-lithographically for defining interconnect. In order to provide metallization providing both good step coverage in via and contact holes and smooth surface for deposition of surface metallization, a two-stage tungsten deposition is provided.

Abstract: A cross-domain call jacketing system is provided in a computer system that embodies a first hardware (X) architecture to executing X-code in an X-domain and which simulates at least a second computer hardware (Y) architecture executing Y-code in a Y-domain. Cross-domain routine calls are jacketed for services in the cross-domain and for returns after the requested services have been performed. After jacketing X routine calls are transmitted for implementation by the simulating subsystem and Y calls are transmitted for implementation in the X domain. Call parameters are transformed from a representation that uses the call conventions of the calling domain to another representation that uses the call conventions of the called domain. Data in the mem-ory is generally globally accessible and the Y calls include data references that require memory access handling in the X domain. A first jacketing table is provided for each executable routine in the X domain. A second jacketing table is provided for each ex-ecutable routine in the Y domain. A run-time jacketing routine is driven by the jacketing tables to drive the call parameter trans-formations needed to complete cross-domain calls.
