Patent CA-2081851-A1 (CA)
Inventor: BIAGIOTTI GUGLIELMO
IPC: B65H19/29
Filed: 1992-10-30
Abstract: The glueing apparatus includes a pair of endless conveyor members (13, 15) whose active branches (13A, 15A) are parallel, with one superimposed above the other and spaced apart to an extent corresponding to the diameter of the rolls or logs (R) and moving in the same direction whereby to move the log forward.          The upper active branch  (15A)  extends further than the lower active branch  (13A).   Unwind mechanism  (31)  for unwinding the tail (L) of the material of the log (R) is located upstream of the  lower  endless  conveyor member  (13)  and controlled by an optical sensor which checks the length of said tail.  Downstream of the lower endless conveyor member (13) a glue dispenser (58) dispenses glue from below onto the outer surface of the log.  A subsequent rewinding station  (R)  is located downstream of the lower continuous conveyor member (13).

Title: Method of item selection for computerized adaptive tests
Inventor: SWANSON LEONARD C
IPC: G09B19/00
Filed: 1992-12-03
Abstract: ABSTRACT OF THE DISCLOSURE               A method is disclosed for incorporating into the construction of adaptive tests expert test development practices.  The method is an application of a weighted deviations model and an heuristic for automated item selection.  Taken into account are the number and complexity of constraints on item selection found in expert test development practice.  The method of the present invention incorporates content, overlap, and set constraints on the sequential selection of items as desired properties of the resultant adaptive tests, rather than as strict requirements.  Aggregate failures are minimized in the same fashion as in the construction of conventional tests.  The extent to which restrictions on item selection are not satisfied is then the result of deficiencies in the item pool, as it is with conventional tests.

Title: Arrangement for anchoring a rod-shaped tension member of composite fiber material
Inventor: HERBST THOMAS
IPC: E21D21/00
Filed: 1992-12-18
Abstract: ABSTRACT OF THE DISCLOSURE An anchoring arrangement for use in underground mining or foundation work or as a reinforcing element for concrete includes a rod-shaped tension member of composite fiber material which has, over at least an anchoring portion thereof, a helically extending external thread with ribs formed by impressing valleys in the tension member. An anchoring member having a corresponding internal thread can be screwed onto the tension member. For obtaining a radial pressure on the tension member as a result of a wedge effect, the angle of inclination of the sides of the thread relative to the longitudinal axis of the tension member is smaller than 45°. The thread preferably is a flat trapezoidal thread. In an anchoring member which is stiff relative to circumferential tensile forces, the flat angle of inclination of the sides of the thread increases the radial pressure acting on the tension member, which leads to an increased effect into the depth and a higher resistance to shearing. The anchoring member may have a changing circumferential tensile stiffness over the length of the threaded engagement with the tension member, so that the anchoring member can expand at the point of highest stress concentration, with the result that a change in length of the tension member may occur.
Patent CA-2087392-A1 (CA)
Title: Double solenoid valve actuator
Inventor: VANRENS RUSSELL J
IPC: H01F7/16
Filed: 1993-01-15
Abstract: Apparatus for moving a reciprocating object, such as a spring biased poppet valve, between a rest and a second position.  The apparatus includes two solenoids, each of which has a core, with one of the solenoids having a larder core and imparting greater force than the other.  The solenoids are mounted in line with one another so that the core of one solenoid is adapted to contact the core of the other, with the latter being adapted to contact the object.  A first solenoid provides a driving force to the object to move it in opposition to a biasing force and the second solenoid holds the object in its moved position when the first solenoid is de-energized.  When the core of the first solenoid is in its rest position, it is out of contact with the core of the second solenoid and this enables the biasing force of the object to rapidly move to its rest position upon de-energization of the second solenoid.

Title: Process for producing enzymes having superoxide dismutase activity, novel superoxide dismutase enzymes and novel pharmaceutical compositions comprising enzymes having superoxide dismutase activity
Inventor: BREHM JOHN K
IPC: C12N15/09
Filed: 1991-08-02
Abstract: The genes (sod) encoding Bacillus stearothermophi-lus and Bacillus caldotenax Mn-superoxide dismutase have been cloned in Escherichia coli and their entire nucleotide sequences determined. With the exception of the post-translationally cleaved N-terminal methionine residue, the predicted amino acid sequence of the B. stearothermophi-lus enzyme (BSMnSOD) exhibits 100 % similarity to the previously determined amino acid sequence. The B, caldoe-nax enzyme (BCMnSOD) differs by two amino acids from BSMnSOD. Both recombinant MnSOD's were shown to be functionally active in E. coli, both in vitro and in vivo, and were expressed to 47 % of the cells soluble protein by coup-ling their transcription to the E. coli trp promoter. The pharmaceutical use of these bacterial superoxide dismu-tases is described.

Patent CA-2093670-A1 (CA)
Inventor: GEARY JAMES E JR
IPC: D04H1/54
Filed: 1991-10-29
Abstract: A method of preparing porous fiber reinforced polymer composite sheets has been developed to allow a more efficient pre-heating of the sheet prier to molding and includes the steps of blending reinforcing fibers with resin matrix forming fibers to form a web. This web is then heated to a temperature wherein the resin matrix forming fibers melt and envelope the reinforcing fibers, tacking them together at crossover points. The resultant web can then be directly heated very efficiently for molding. This web is highly porous allowing rapid heating at moderate pressure differentials during subsequent preheat steps. The microstruc-ture created when the resin matrix forming fibers are initially melted further enhances heating capability because the structure re-tains porosity during the subsequent heating step required for molding.  Because the resin matrix forming fibers initially were un-iformly blended, a highly uniform distribution of polymeric material within the reinforcing fiber matrix yields molded parts with very uniform properties.

Abstract: A switching regulator comprises a single transformer having a primary winding connected in an input circuit for receiving direct-current energy and a secondary winding connected in an output circuit, and a switching transistor connected in series with the primary winding. A high frequency pulse generator triggers the switching transistor so that it interrupts the direct-current energy at a high frequency. A rectifier is provided for converting high frequency energy developed in the secondary winding into direct-current output energy, which is maintained constant by controlling the high frequency pulse generator. A low voltage detector produces a signal when the direct-current energy in the input circuit falls below a specified value. in response to the signal from the low voltage detector, constant direct-current energy is derived from a battery and applied to the output circuit as backup power.
