Abstract: IMPROVED PROCESS FOR FORMING SUBSTANTIALLY      UNIFORM SEED ASSEMBLAGES CAPABLE OF     Abstract of the Disclosure An efficient process employing cytoplasmic male sterility is provided wherein seeds capable of forming F1 hybrid Glycine max plants and restorer plants for the same simultaneously are formed in bulk in a single planting area and the seed harvest subsequently is segregated to form two substantially uniform seed assemblages.  The parent soybean plants are provided with distinctly colored maternally-derived seedcoats wherein the genes for seedcoat coloration are homozygous dominant in one parent and homozygous recessive in the other parent.  The resulting seeds are harvested in bulk and are separated on the basis of the soybean seedcoat coloration.  Soybean plants resulting from the planting of the seeds capable of forming F1 hybrids upon self-pollination form seeds which substantially uniformly exhibit maternally-derived light-colored seedcoats in the F2 generation thereby enabling the grower to produce a substantially uniform soybean harvest.  The other seeds formed in the initial planting area are capable of substantially uniformly forming restorer soybean plants in a subsequent planting.

Abstract: ABSTRACT      A reconfigurable remote control transmitter for use with a plurality of remotely controlled products, each of which is normally controlled with one or more signals from an associated remote control transmitter.  The reconfigurable transmitter has a plurality of input keys and operates either in a Learn mode in which it may store indications of signals generated by the remote control transmitter from one or more of the products or a Run mode in which it selectively transmits stored signals in response to one or more keyed inputs.  During the Learn mode a selected sequence of operations to be performed by one or more of the products in response to a first selected key sequence may be stored.  The transmitter indicates whether proper storage has occurred by determining whether the signal being received by the transmitter from a remote transmitter is of proper strength to permit an indication thereof to be correctly stored.  During the Run mode stored signals are transmitted in a predetermined order in response to the performance of the selected key sequence to cause the selected sequence of operations to be performed.  During the Run mode the transmitter may utilize one or more timers settable to a selected date and time to control the transmitting of stored signals or signal sequences,

Abstract: ABSTRACT OF THE DISCLOSURE    A connection structure between lead frames and a base plate of aluminum nitride, to be applied as a connection structure between components of a semiconductor apparatus, comprises the base plate formed of a sintered body of aluminum nitride on which a semiconductor device is to be mounted, the lead frames including, as a main material, iron alloy containing nickel in 29 wt.% and cobalt in 17 wt.%, and silver solder for joining the base plate and the lead frames.  A surface of the lead frame to be joined to the base plate is formed of oxygen-free copper of a high plastic deformativity to relieve, by plastic deformation of itself, a thermal stress caused by a difference between a thermal expansion coefficient of the base plate and that of the lead frame in a cooling process at the time of soldering.  Preferably, only a portion of each lead frame to be joined to the base plate comprises an inner layer portion of iron alloy containing nickel in 29 wt.% and cobalt in 17 wt.%, and an outer layer portion of oxygen-free copper.

Title: Directional drilling assembly
Inventor: BOHME CAL G
IPC: E21B7/04
Filed: 1989-05-02
Granted: 1995-07-04
Abstract: Joints of drill pipe are provided, formed of inner and outer tubes which are co-extensive and radially spaced apart.          The joints are connected to form a drilling string having inner and outer tubular members having drive and bit ends.   The drilling string extends from a generally horizontal mast.   A bent sub assembly is attached to the bit end of the outer tubular member.  The drill bit is attached to the bit end of the inner tubular member  by  a downhole  drive  assembly.    A  separate rotational drive assembly is provided at the mast for each of the tubular members.   Means are provided at the mast for axially advancing and retracting the drilling string, so as to apply push and pull forces through the outer tubular member.  The drilling mud is brought into the annulus, between the tubular members, at the drive end of the string and is crossed over through a port into the downhole drive assembly immediately adjacent the bit.          By having the bent sub assembly attached to the normally non-rotating outer tubular member, the effect of back-torque arising from the bit  is  avoided and better directional  control  is achieved.   By using the annulus as the supply path for the drilling fluid and keeping the bore of the inner tubular member empty and non-obstructed, a directional survey instrument can be brought within about 6 feet of the drill bit to obtain accurate directional surveys.   The assembly is adapted, when drilling directionally, to steer the bit with the stationary outer tubular member and bent sub assembly and to drill with the rotating inner tubular member and attached downhole drive assembly and bit.

Abstract: ABSTRACT    A pin grip array zero insertion force connector has 10,000 or more normally closed contacts provided in rows on a motherboard.   Alternating rows of contacts respectively include first and second type contacts, and drawbars are provided between the rows of contacts.          Alternate  drawbars  are  caused  to  slide  in opposite directions, thereby engaging the drawbars with one of the two tines of each contact in the rows of contacts on either side of the drawbar.   An actuator mechanism is provided at each end of the rows of contacts and drawbars to engage and slide the drawbars.  To reduce the force necessary to operate each actuator mechanism, the  actuator  mechanisms  may  be  divided  into  sub-actuator mechanisms which are  individually actuated.          The drawbars comprises a drawbar support strip which engages the actuator mechanisms and an interposer body molded to retaining tabs on the drawbar support strip.     WP\MEM\AMDH5879.001

Abstract: A PACKET SWITCHING ARCHITECTURE PROVIDING         ENCRYPTION ACROSS PACKETS Abstract Apparatus for preventing the unauthorized detection of the start and end of packets being communicated within a packet switching system. The packet switching system comprises a plurality of packet switching networks that are interconnected by trunks. Each switching network has a number of trunk controllers with each terminating one of the trunks interconnecting that network to other networks. Each controller has an encrypting circuit for only encrypting the flag of each packet before the packet is transmitted on the connected trunk and a decrypting circuit for decrypting the flag of each packet received from the connected trunk. The decrypting circuit on the receiving side of a trunk recovers flag synchronization with the encrypting circuit on the transmitting side of the trunk by the exchange of special packets. Each flag comprises a plurality of bytes. The decrypting circuit can automatically adjust for a predefined number of errors in the flag bytes or a predefined number of flag bytes appearing in the data of a packet.

Abstract: A programmable system for controlling the operation of a plunger  completion  oil  or  gas  production  well  to  optimize production from the well.   The controller operates one or more motor valves controlling the well in accordance with programmable values of off-time,  on-time and exhaust-time.   The controller monitors whether or not a plunger arrival signal is received on each cycle of intermitting the well and changes either the off-time or the exhaust-time for the next cycle in response thereto.          In oil well mode,  the off-time is decreased slightly for each cycle following a cycle in which plunger arrival occurred and increased slightly for each cycle following one in which it did not.   In gas well mode,  the exhaust-time is increased slightly for  each  cycle  following  a  cycle  in  which  plunger  arrival occurred before on-time expired and decreased slightly for each cycle following one in which it did not.
