Title: Method of somatotropin solubilization and naturation
Inventor: BENTLE LARRY ANDREW
IPC: C12P21/00
Filed: 1986-02-21
Granted: 1990-04-24
Abstract: METHOD OF SOMATOTROPIN SOLUBILIZATION AND NATURATION ABSTRACT A method for solubilization and naturation of somatotropin protein from refractile bodies of host cells is disclosed. The method embraces the discovery that an aqueous urea or dimethylsulfone solution can be effectively used to solubilize refractile bodies containing such somatotropin protein. Once solubilized, somatotropin protein can be natured in a urea or dimethylsulfone solution by contacting the solution with a mild oxidizing agent for a time sufficient to result in the formation of the disulfide bonds. Naturation can efficiently occur even at high protein concentration, in an impure preparation and in the absence of reducing agent.

Patent CA-1301309-C (CA)
Title: Protocol for handling transmission errors over asynchronous communication lines
Inventor: MELTZER CLIFFORD B
IPC: H04L1/00
Filed: 1986-12-04
Granted: 1992-05-19
Abstract: ABSTRACT OF THE DISCLOSURE     A system or scheme for automatic detection of and recovery from transmission errors in the asynchro-nous communication mode at the data link level with complete transparency at the higher levels is dis-closed wherein the transmissions are in the form of a sequence of data packets,  and an improved combination of end-of-text (ETX) bytes along with checksums is used in each data packet to  detect errors. The ETX character is dynamically selected for each packet  after  the  data  comprising  the packet has been assembled. This character is coded differently from the remaining character codes in its respective packet and is made the second byte thereof  following the start-of-text byte  (STX).   The third byte in each packet is made the comple-ment of the preceding ETX byte, the latter of which is also made the last byte in the packet.  Thus, the second and last bytes in each packet are iden-tical, and different from all the other bytes, and the third byte is their complement. Other bytes m each packet include: one byte indicating the  lo-cation of the packet in a set in a given trans-mission  sequence;  a  byte  distinguishing  the packet's set from other transmission sequences: two bytes indicative of the number of data bytes in the packet; one byte operating as a control character indicating the functional nature of the  packet; data bytes; and, two checksum bytes which precede the last ETX byte. Among the advantages of trans-missions using packets  containing the  foregoing improved combination of bytes, is the fact that all transmission errors will be detected and upon de-tection of an error in a packet, the transmitter is immediately notified and retransmission is car-ried out only from the erroneous packet rather than from the beginning of the entire sequence as in the prior art.

Title: Package structure for spark plugs
Inventor: HADTKE FREDERICK B
IPC: B65D85/00
Filed: 1987-01-14
Granted: 1990-12-04
Abstract: ABSTRACT OF THE DISCLOSURE An improved package structure for shipping and displaying spark plugs is disclosed.  The package structure includes a generally flat lid connected by a hinge  along one end thereof to a base.  The lid and the base have respective cooperating curved channels throughout their peripheries.  In a closed position, the lid channel is received within the base channel throughout the periphery thereof, so that the lid is securely but releasably retained in the closed position and the overall strength of the package structure is increased.  There are two raised portions integral with the bottom of the base.  The raised portions have recesses for receiving the opposed ends of a plurality of spark plugs to support them in alternating fashion within the base.  Two lips extend partially into an upper portion of each of the recesses to engage the ends of the spark plugs within the recesses.  A cardboard insert further increases the strength of the package structure.  A bottom portion of the insert extends throughout the base between the opposed raised portions and the front and rear ends.  A vertical portion of the insert extends upwardly along the rear end of the package structure adjacent the hinge.  A top portion of the insert extends throughout the lid.  The sides of the base are tapered slightly inwardly from top to bottom, and a plurality of feet may be formed on one side of the package structure extending outwardly therefrom to give the package structure the ability to stand upwardly on one side.  The entire package structure can be vacuum thermo formed from a single piece of transparent industrial grade polyvinylchloride material.

Title: Surface acoustic wave gas flow rate sensor with self- heating feature
Inventor: BRACE JOHN G
IPC: G01F1/69
Filed: 1987-05-11
Granted: 1991-07-16
Abstract: ABSTRACT OF THE DISCLOSURE     A surface acoustic wave device for measuring the mass flow rate of a gas includes a surface acoustic wave delay line formed of a piezoelectric substrate and having a temperature coefficient of delay on the order of 10-4/°C.  The substrate has disposed thereon a transmitting and a receiving interdigital transducer, the transducers being configured to have an operating frequency in the range of from 10MHz to 1000MHz.  That portion of the substrate located between the transducers defines a propagation region and has a medium deposited thereon for absorbing a portion of the acoustical and/or electrical energy flowing thereacross.  This absorbed energy increases the temperature of the propagation region over that of the surrounding ambient.    A mass flow of the gas across the sensor will decrease its temperature and result in an upward shift in the resonant frequency.  A suitable amplifier and resonant frequency detector may be coupled to the sensor for detecting the change in resonant frequency, thereby permitting mass flow rate measurement.

Abstract: ABSTRACT OF THE DISCLOSURE           A doctoring apparatus employs a doctor blade having  a  length greater  than the  face  length of  the surface being doctored.  A blade holder applies an inter-mediate portion of the blade to the doctored surface.          The blade  is movable  longitudinally through the blade holder, and has continuing portions extending beyond the ends of the holder.   At least one clamp acts on one of the continuing blade portions. The clamp is adjustable between  a  closed  setting  preventing  relative movement between it and the blade, and the open setting permitting such relative movement.  A drive reciprocates either the blade holder or the clamp in one direction when the clamp is closed and in the opposite direction when the clamp is opened, thereby causing the blade to move incrementally in  one  direction  across  the  surface  being  doctored.
