Title: Method of bone apposition rate determination
Inventor: TAM CHERK SHING
IPC: G01N21/77
Filed: 1995-09-08
Abstract: A protocol for measuring the bone apposition rate of a subject using a label such as a tetracycline antibiotic, a dye such as alizarin (1, 2 -dihydroxyanthraquinone), or calcein The interval between administering first and second doses of the label is about 72 hours or less. Usually, tetracycline is delivered to an animal by a parenteral route and the interval is in the neighbourhood of 48 hours Within about one hour to about forty-eight hours, the subject organism is sacrificed and a bone sample obtained therefrom.

Title: Atm-communication system for statistical multiplexing of message cells
Inventor: SCHNEEBERGER STEFAN
IPC: H04L12/54
Filed: 1995-09-26
Abstract: The ATM communication system comprises a plurality of up-stream interfaces (SMU), at least one multistage funnel of switching elements (SE)connected thereto and at least one downstream interface (SMU), whereby each of the switching elements comprises a plurality of inputs and at least one output to which a logical queue is associated. The logical queue of each of the switching elements (SE) is common for different traffic classes. For the filling of the logical queues to each of the traffic classes a prede-termined threshold is defined. In case of exceeding the threshold for the respective traffic class by receiving a message cell for this traffic class a back pressure signal is transmitted only to the switching element or upstream interface, respectively, just transmitting this message cell. The transmission of message cells is stopped by this switching element (SE) or upstream interface (SMU), re-spectively, for a predetermined period of time periodically until resetting the back pressure signal.

Title: Boxed pay-out reel for optic fiber cable or wire or the like, with smooth pay-out, high-impact and cable end holding features
Inventor: BASS BENJAMIN ALLEN
IPC: B65H75/38
Filed: 1995-10-19
Abstract: A boxed spool assembly of the present invention includes a spool assembly, a pair of end plates for supporting the spool assembly for rotation, and a box in which the spool assembly and end plates are placed. The bottom of the box is self-locking and requires no tape. Further, the box is constructed so that the overlapping of multiple layers of corrugated fiberboard is avoided in the bottom of the box so that the spool assembly can rotate without interference. The box includes starburst cuts to hold the loose end of cable or wire wound on the spool assembly so that a user can readily locate the loose end. One starburst cut has a slit communicating with a horizontal slot. Cable or wire can be paid-out or held in position by pulling the cable to the slot or starburst cut, respectively, by the slit. The end plates include polycarbonate material and have openings corresponding with openings in the box, to provide handholds for the user. The end plates havearbors protruding away from the plate surfaces of the end plates to hold flanges of the spool assembly away from the end plates for frictionless rotation. The arbors of the end plates that support the spool assembly have annular flat ledge surfaces to confine the flanges of the spool assembly away from the end plates. The protrusions of the arbors are drafted or tapered to cause the spool assembly to be centered in the box and to ride away from the end plates. Corner supports are provided on the end plates to prevent the corners of the end plates from cuttingthrough the box and also to maintain the box in the proper configuration. The arbors and corner supports include rib reinforcements. The boxed spool assembly is sized in accordance with industry standard shipment sizes.
Patent CA-2161804-A1 (CA)
Inventor: ISAKSSON SVEN
IPC: A61K35/14
Filed: 1994-05-06
Abstract: This invention relates to a process for reduction of virus inactivating chemicals and/or detergents in an aqueous composition containing a water-soluble plasma protein. By selecting a suitable combination of temperature and concentration above 0.5 M of a salt with a high salting out effect according to the Hofmeister series, vesicles containing the virus inactivating chemical and/or detergent are formed. These vesicles are removed from the aqueous phase, e.g. by phase separation or filtration, and the protein thereafter isolated from the aqueous phase. The water-soluble plasma protein can be e.g. antithrombin III, transferrin or albumin. When the aqueous phase comprises e.g. a salt of citrate or sulphate in a concentration above 1 M at room temperature, the reduction of virus inactivating chemical or detergent can be as high as 2000 times or more, giving a final concentration below 5 ppm.

Patent CA-2165121-A1 (CA)
Inventor: NODA KAZUO
IPC: G11B7/126
Filed: 1995-12-13
Abstract: In an optical information recording and reproducing apparatus, information is recorded or reproduced by moving a recording medium relative to an optical head.  In order to execute information recording onto the medium in the course of  the  relative  movement  involving  acceleration  and deceleration, the generation timing and intensity of a light beam to be generated in correspondence with the information to be recorded are controlled in response to a varying speed of the relative movement so that data pits to be formed in the recording medium can be standardized in pitch and size irrespective of the relative movement speed.  Also, in order to permit information reproduction from the medium in the course of the relative movement involving acceleration and deceleration, reproduction timing of data read by the optical head is set in synchronism with variation in the relative movement speed so that the data can be reproduced at proper timing irrespective of the relative movement speed.   With such arrangements, there can be achieved a highly increased information    recording/reproduction    speed,    extended information recording area,  reduced size and cost of the apparatus, and reduced power consumption in the apparatus.

Inventor: AIELLO WILLIAM ANTHONY
IPC: G06F7/58
Filed: 1995-01-18
Abstract: Methodology and concomitant circuitry to generate crytographically strong pseudo-random bit streams utilize secure block cypher encoders. Typically, each block cypher encoder (150) has a first seed (x?) and a random key (k) as an input. In the most basic realization of the methodology and circuitry, the ouput of each encoder is fed back (151) to connect to its input. The first seed serves as the initial input, and each subsequent input is the immediate output. Each bit in the crytographically strong pseudo-random bit stream is related (160) to an inner product between each input to the encoder and a second seed (h).
Patent CA-2180824-A1 (CA)
Inventor: ARSENAULT ARMAND JOSEPH
IPC: B60P3/41
Filed: 1996-07-09
Abstract: An apparatus for transporting elongated loads, such as logs, particularly in small scale logging operations, includes a longitudinally extending body and a transversely extending support member having a center portion connected to the body.  Laterally spaced apart left and right legs extend downwardly from the center portion to weight bearing structure cooperating with lower ends of the legs to support the apparatus upon the ground. A load supporting device cooperates with the load and the body to support the load beneath the body. A restricting flexible tension link, for example a length of link chain, cooperates with lower ends of each leg and with a tensioning device which cooperates with the body and applies tension to the links to restrict the legs from excessive movement relative to the body. The apparatus has particular applications in skidding logs where conventional heavy duty skidders are inappropriate because of environmental or economic concerns. The apparatus is light and inexpensive and is towed behind a relatively lightweight recreational all terrain vehicle or snow vehicle.
