Title: Portable texturing machine
Inventor: HOWE DAVID
IPC: B05B7/12
Filed: 1990-05-02
Abstract: ABSTRACT OF THE DISCLOSURE     A portable texturing system is disclosed which includes a small spray unit and a source of portable compressed air which may simply be a small tank which the workman may wear on a belt or shoulder harness.   The spray unit includes a reservoir for holding a  charge  of  texturizing mixture  and  a  cap  assembly incorporating a  mixer/spray mechanism.   In  use,  the cap  is positioned  below  the  reservoir  such  that  the  texturizing mixture can flow by gravity and suction to the spray mechanism.          The cap assembly includes a quick connect coupling and a valve for receiving and controlling air from the supply.  A discharge nozzle is provided for directing the compressed air/texturizer mixture toward a wall area to be texturized.   A mixing region within the cap assembly permits the texturizing mixture to be entrained with a stream of compressed air and discharged from the  nozzle  whenever  the  valve  is  actuated.  Adjustment structure  for regulating the  rate  at which  the  texturizing material is entrained is provided in the mixing region and, in some  embodiments,  is  adjustable  as  by  a  mechanism  which provides adjustment to the area available for the texturizing material to enter the discharge nozzle.   In one particularly simple and reliable embodiment, the area is established by the provision of a pair of fixed size apertures in the wall of a tube which also serves as the discharge nozzle.

Title: Disc case
Inventor: SAKURADA MASATAKA
IPC: G11B23/03
Filed: 1990-06-18
Abstract: A disc case for releaseably receiving a disc therein includes a housing having a disc receiving portion formed therein, a shutter adapted to slidably move along one brim of the housing to properly expose a part of the disc to the outside  and  a  spring  member  having  at  least  two  turn portions  to  generate  a  resilient  force  active  in  the direction of closing the shutter,  one end of the spring member being engaged with a groove formed in one corner section of the housing, while other end of the spring member being engaged with one side end of the shutter opposite to the corner section.   The one turn portion located in the vicinity of another side wall of the housing extending at a right angle relative to the one side wall of the housing has a part of the spring member extending from the one turn portion, wherein the extended part of the spring member is bent in the same direction of turn of the one turn portion.   With such construction, no waste material is produced from the boundary wall of the housing, because frictional contact of the spring member with the boundary wall of the housing does not occur at the time when the shutter slidably moves in the opening/closing direction.  Once the spring member is held in a fully opened state, it is properly received in a substantially triangular narrow space in the corner section of the housing.

Title: Protective sheath for a cannula
Inventor: OGLE GEORGE B II
IPC: A61J1/00
Filed: 1990-08-17
Abstract: IMPROVED PROTECTIVE SHEATH FOR A CANNULA            ABSTRACT OF THE DISCLOSURE      A protective device for enclosing the scarf of a cannula includes an elongated sheath having a bore extending through it.   The cannula is sealed in the bore of the sheath with the scarf end of the cannula located within and adjacent one end of the sheath, which is spaced from the scarf.  The end of the sheath adjacent the scarf end of the cannula has at least one cutout portion which can receive the edge of a flexible bag or a flexible tubing connected to a Y-site for intravenous injection.  A socket carried by the sheath at the other end of the cannula has an opening through it  in communication with the bore through the cannula.  The socket opening tapers outwardly away from the cannula for receiving a tapered nozzle on a syringe.     Preferably,  the  sheath  surrounds  the  socket  and carries inwardly extending ears which act as male threads for  engaging  internal  threads  in  a  skirt  around  the discharge nozzle of a syringe.   The skirt makes a slip fit against the  inside of the sheath surrounding the socket and inwardly extending ears.  Preferably the outside surface of the syringe skirt is irregular to provide an increased coefficient of friction against the interior surface of the sheath.

Title: Production of biologically active insulin-like growth factor i from high expression host cell systems
Inventor: MILLER JAMES A
IPC: C07K19/00
Filed: 1990-08-24
Abstract: Abstract "PRODUCTION OF BIOLOGICALLY ACTIVE INSULIN-LIKE          GROWTH FACTOR I FROM HIGH EXPRESSION HOST CELL SYSTEMS"         A novel method for refolding reduced IGF-I is provided in accordance with the present invention.  The method is carried out by providing additional positive charge at the amino terminal end of the IGF-I molecule by the presence of a short leader sequence.  The additional positive charge on the met-end of the IGF-I molecule has been found to enable recombinant IGF-I to refold simply by stirring solubilized inclusion body protein for between 2-16 hours, or overnight.  The present invention also provides a novel fusion protein intermediate of IGF-I attached to the positively charged leader sequence.

Abstract: A digital phase locked loop is employed to realize an output clock signal from a reference signal having a frequency which is not an integer multiple of the output clock signal frequency. This is realized by employing a programmable divider for dividing the reference signal which is dynamically controlled by a controllably variable base divisor. The base divisor control is responsive to the reference signal and to a phase error signal. The base divisor is generated to obtain a desired fractional division of the reference signal frequency and in a manner tominimize the amplitude of any resulting "high" frequency jitter in the output clock signal from the loop.
