Patent CA-2040566-A1 (CA)
Title: Biosynthesis of proteins in transgenic drosophila
Inventor: DAVIES PETER L
IPC: C12N15/12
Filed: 1991-04-16
Abstract: Abstract Drosophila melanogaster have been shown to express large quantities of foreign proteins from genes placed under divergent transcriptional control of host gene promoters.          The chimeric genes are introduced into flightless mutant Drosophila through P-element transformation.   Transformed adult females accumulate the protein in their hemolymph. The protein can be purified and recovered in high yield from the hemolymph by conventional techniques.
Patent CA-2041345-A1 (CA)
Title: Thread form
Inventor: DELANGE RICHARD W
IPC: F16L15/00
Filed: 1991-04-26
Abstract: ABSTRACT OF THE DISCLOSURE     The overall description of this invention is a truncated buttress-type thread form that incorporates a reverse-angle tension load flank with a compression flank and a torque shoulder; the thread does not have any radial interference designed into it, but the hooked tension flank does tend to pull the pin and box together once the torque shoulder is engaged.   The mating compression flanks have designed into them a minimum amount of clearance prior to the shouldering action, which then closes to zero or very near zero at the moment the shoulder is engaged.  This drawing together is due to the tendency of the hooked threads to pull together at shouldering if there exists no radial interference in the thread body.   The thread roots and crests can be tapered, parallel to the taper of the thread body, or flat and parallel to the pipe axis but maintain adequate clearance to allow some closure once the shoulder is engaged so that the compression flanks can draw together.

IPC: H04L12/26
Filed: 1991-05-14
Abstract: Transmission quality assessment arrangement for a communication switching system wherein a stream of cells of information is transmitted from an input (I) to an output (O) over a same communication path.  It is adapted, at the input, to insert in the cell stream test cells each having a tag indicative of its position in the resultant cell stream and to count, at the output, the position of each test cell in the latter cell stream.  From the difference of the position counted and that stored in the leg of a test cell an indication of the number of added or lost cells -indicative of the transmission quality - is derived.

Abstract: Each link (1) has a main portion (2) of which the inner side has two semi-cylindrical recesses (4a, 4b) and of which one of the large sides has two semi-cylindrical extensions (5a, 5b) designed to fit into and rotate coaxially in the recesses (4a, 4b) of an adjacent link (1). A retaining element (7) has semi-cylindrical projections (9a, 9b) which fit into recesses (6a, 6b) in the side extensions (5a, 5b). All these semi-cylindrical parts (4a, 4b; 5a, 5b; 6a, 6b; 9a, 9b) are coaxial so that a certain amount of rotation is possible between adjacent links. A pin (3) provides the connection between these links by fastening each link (1) onto the retaining element (7) which co-operates with the extension (5a, 5b) of an adjacent link. This design avoids the need for the pivots which have heretofore been used.

Title: Reduced mass absorbable surgical fastener and retainer
Inventor: GREEN DAVID T
IPC: A61B17/064
Filed: 1992-04-06
Abstract: A bioabsorbable surgical fastener comprising a fastener member and an interlocking retainer member. The surgical fastener has a total mass of less than 4 mg/transverse mm, thereby reducing the amount of foreign matter present at the wound site and facilitating faster resorption, while effecting hemostasis. The retainer member preferably has longitudinally extending slots on the lateral sides of the retainer for allowing transverse expansion of the columnar members into which the prongs of the fastener member are locked. Fins on both the lateral and transverse sides of the prongs provide extra strength, and stability during implantation. Stopping surfaces prevent the fastener's barbed tip from exiting the opposite side of the retainer.

Title: Apparatus for equipment unit protection switching
Inventor: BROCKWAY ROBERT C
IPC: H01H35/00
Filed: 1992-04-24
Abstract: An equipment unit protection switch from an in-service equipment unit to a standby equipment unit is realized prior to any movement of the active equipment unit about to be removed from an equipment frame in which it is inserted. This is achieved by advantageously incorporating apparatus for generating an equipment unit removal indication signal that enables a controller to anticipate the removal of the equipment unit from the equipment frame. To this end, the equipment units employ an equipment unit latch and an associated switch to generate the equipment removal indication signal. Initial movement of the latch causes the equipment unit removal indication signal to be generated prior to any movement of the equipment unit in the frame in which it is inserted. (FIG. 4)

Inventor: NISHIOKA TAKAO
IPC: B24B7/22
Filed: 1992-07-08
Abstract: An industrially feasible method of grinding silicon nitride ceramics.  The method provides a sufficiently smooth surface.  Namely. the surface has a maximum height-roughness Rmax of 0.1 micron or less and a ten-point mean roughness Rmax of 0.05 micron.  Further, with this method, surface damage can be repaired while grinding.  The vertical cutting speed of a grinding wheel into a work should be within the range of 0.005 - 0.1 micron for each rotation of the working surface or the wheel and change linearly or stepwise.  The horizontal machining speed should be within the range of 25 to 75 m/sec.  With this arrangement, the contact pressure and grinding heat that generate between the work and the hard abrasive grains during grinding are combined.  In other words. mechanical and thermal actions are combined.

Abstract: The present invention provides methods for treating continuous lengths of resin-impregnated sheets (11) so that they can be supplied in roll form, i.e., like a bolt of cloth, for subsequent processing or use. The methods feature the step of winding the continuous length (11) and a separation layer (12) of a material into a roll (10) with the layer separating successive wraps of the continous length of sheets, followed by a curing step if the resin is a thermosetting resin or by the application of heat and/or pressure otherwise. The continuous lengths optionally may comprise at least one sheet of film, too. The separation layer (12) of material remains separable from the continuous length (11) after treatment. Composite articles made from certain of these continuous lengths are ballistic resistant.
