Inventor: DJEGA-MARIADASSOU GERARD
IPC: C01G37/00
Filed: 1987-12-02
Granted: 1992-02-18
Abstract: ABSTRACT OF THE DISCLOSURE    A  method  for  manufacturing a zinc oxide based powder by  coprecipitation with one or more additions is disclosed.        The method comprises:    -  a  step for the preparation of one or more solutions by  dissolving  defined quantities of salts of elements that go   into  the   composition   of   the  powder:  zinc  and addition(s).    -  a  step  for  the  preparation  of a buffer solution pre-saturated   by   the  said  elements,  the  said  buffer solution  possessing  a  pH which is defined so as to cause the  precipitation of the hydroxylated compounds of elements corresponding to   the   elements  saturating  the  buffer solution, -  a  step  during which the solutions are added to the said  buffer  solution, the drop in the pH being compensated for  by  the addition of a base and the volume of the buffer solution being kept constant by drawing off excess liquid, -  a  step  during  which  the  precipitate obtained is treated to obtain the said powder.

Title: Torque wrenches
Inventor: WALTON JOHN N
IPC: B25B13/46
Filed: 1988-01-19
Granted: 1991-09-24
Abstract: ABSTRACT     The double-acting piston of a torque wrench has a piston rod, the free end of which receives a pin which is guided at each end in straight or curved guide channels in the wrench housing.  The pin passes through drive shoes, slidably received in slots at the upper end of a drive lever.  The drive lever as it reciprocates rotates a ratchet wheel, the ratchet wheel having a square central bore to receive a square drive shaft journalled in the housing.  If a constant force is applied, the torque wrench provides a substantially constant torque, particularly if the guide channels are curved to compensate for frictional losses.  The ratchet mechanism includes rollers which float between grooves in the ratchet wheel and sockets in the drive lever.

Title: Arrangement for training and practicing a game of golf
Inventor: SVENSSON ALLAN
IPC: A63B43/00
Filed: 1988-03-02
Granted: 1992-08-25
Abstract: Arrangement for training and practicing a game of golf Abstract According to the invention an arrangement is proposed for training and practicing ball games, in particular golf. The arrangement can be used indoors as well as outdoors and comprises, on the one hand, a scoring means, preferably a panel (20) with a specifically prepared surface (28) and, on the other hand, a number of "golf balls" (10) having a surface likewise specifically prepared. The said surface preparation is such that the panel immediately catches and retains a ball when hit by it, so that the hitting point on the panel can be observed and taken down. However, the balls do not cling to each other or to carpets, curtains etc. occurring indoors. The surface of the panel (20) is prepared with so called Velcro material (25). By means of the arrangement a game of golf can be practiced while imitating the play on a real golf course and while using the so called score card of this course. For training so called "putt" stroke the panel. (20) can be replaced by a small cylindrical body or a thin circular plate of the same diameter. To catch the ball upon a hit the periphery of the body and the top side of the plate are prepared in the same way as the surface of the score panel (20) mentioned above.           (Fig. 5)

Abstract: Abstract of the Disclosure BORING TOOL FOR MACHINE TOOL A boring tool, is made from simple bar stock without significant external machining of the tool body.  By providing a longitudinal bore which intersects a transverse slot, a longitudinally slidable wedge with splines can cooperate with a disc carried by a tool bar slidably received in the transverse slot.  To ensure the most precise alignment between splines of the wedge and splines of a cooperating disc in the tool bar, the disc of the tool bar is attached to the tool bar with epoxy cement while the splines of the disc are engaged with the splines of the wedge.  With the splines of the wedge being angularly offset from the lon-gitudinal axis of the wedge, translation of the wedge will ensure accurately controlled movement of the tool bar.

Title: Method of curing a compressible printing blanket and a compressible printing blanket produced thereby
Inventor: GAWOROWSKI ANDREW J
IPC: B32B3/26
Filed: 1988-05-12
Granted: 1991-09-24
Abstract: Abstract of the Disclosure A laminated printing blanket having compressible and resilient properties and a method for its production are provided.  The compressible characteristics are provided by disposing an intermediate layer having substantially uniformly distributed voids of substantially uniform size between the substrate layer and the surface layer of the printing blanket.  The voids of the compressible intermediate layer are formed by introducing microcapsules into an elastomeric compound formulated for production of the intermediate layer, and by vulcanizing the intermediate layer at a temperature below the melting point of the microcapsules to a degree sufficient to fix the microcapsules in place within the structure of the intermediate layer.  A final vulcanizing step completes the curing of all layers to produce a laminated unitary blanket.

Title: Plastic-coated optical transmission fiber and an estimating method thereof
Inventor: MASUDA SHIGEO
IPC: G01N3/02
Filed: 1988-12-23
Granted: 1994-06-07
Abstract: ABSTRACT OF THE DISCLOSURE         Optical-transmission  fibers  serve  to  transmit signal over some distance.   Said fibers have traditionally been constructed of a glass fiber; consisting of a central core and an outside clad, a surrounding soft layer around said fiber and a hard layer around the soft layer.  Because of the material construction, said fibers had high dynamic losses.   By altering the materials used around the glass fiber, the present invention has successfully dramatically reduced the dynamic loss and therefore greatly improved the possibilities for signal transmission.  The organic material used to enhance transmission ability may vary but the effect is such that the dynamic loss remains low as compared to any previous art.

Abstract: The present invention relates to a vaccine comprising a polypeptide with antigenic determinants capable of raising neutralizing antibodies against a pathogen. The polypeptide may be functionally associated with a surface membrane of a recombinant, stable. continuous cell line capable of its production.   Alternatively the polypeptide is formed first in functional association with a surface membrane of a recombinant. stable, continuous cell line capable of its production and then dissolved free from the membrane. The polypeptide may also be a truncated membrane-free derivative of a membrane-bound polypeptide.      The derivative is formed by omission of a membrane-binding domain from the polypeptide allowing it to be secreted from a recombinant host cell system in which it has been produced.      In particular the present invention provides for vaccines which are useful against HSV-1 and/or HSV-2 viruses thereby providing protective vaccines against occurrence of herpes infection and a reduction in frequency and severity of herpes infection recurrence in individuals already infected.
