Inventor: SANDERSON ROBERT A
IPC: F04B1/22
Filed: 1999-09-14
Granted: 2013-02-19
Abstract: A piston assembly includes first and second double-ended pistons, a transition arm coupled to each of the pistons, and a rotating member rotating in a first direction about a first axis. The transition arm includes a drive member coupled to the rotating member off-axis of the rotating member. A first counterbalance is mounted to rotate in the first direction, and a second counterbalance is mounted to rotate in a second direction opposite the first direction. The second counterbalance rotates about a second axis offset and parallel to the first axis. Alternatively, the second counterbalance rotates about the first axis. A method of counterbalancing a piston assembly includes mounting a first counterbalance to the piston assembly to rotate in the first direction, and mounting a second counterbalance to the piston assembly to rotate in the second direction.

Title: Improved cryoprotectant solutions
Inventor: WOWK BRIAN
IPC: A01N37/02
Filed: 1999-09-21
Granted: 2012-02-21
Abstract: Surprising new combinations of previously-known and novel cryoprotectants are provided that yield superior recovery of function and viability of living systems after exposure to and removal from said systems. These and related combinations are useful for cryopreservation by vitrification, freezing, supercooling, freezing point depression, or cold storage. It is disclosed that, contrary to current opinion, ideal solutions for cryopreservation are those that vitrify "poorly" (i.e., at higher rather than at lower concentrations). Contrary to expectation, by using relatively "poor" vitrifiers, the water content of the solution is reduced at the concentration needed to vitrify, but the water availability within the solution is believed to be paradoxically increased, thereby increasing viability. A novel method for understanding and predicting non-specific cryoprotectant toxicity is provided based on a new definition of cryoprotectant "concentration", which is the number of water molecules per polar group on penetrating cryoprotectants. Compositions are provided that vitrify at relatively high concentrations, yet surprisingly also devitrify slowly on warming. Databases of novel vitrification/devitrification and toxicity data are provided that allow the ordinary practitioner of the art to select specific solutions or obvious solution variants to meet the user's specific cryopreservation needs.

Title: Wide multiple-chain trenching machine
Inventor: LEMBCKE JOSEPH P
IPC: E02F3/14
Filed: 2001-09-07
Granted: 2005-08-30
Abstract: A multiple-chain trenching machine comprises a prime mover with a trenching head assembly operably connected thereto. The trenching head may be raised, lowered, and/or pivoted relative to the prime mover, and comprises: a) a frame operably connected to the prime mover at a proximal end; b) one or more pairs of proximal and distal primary sprockets mounted on the frame; c) a primary endless-chain digging assembly engaged with and circulating around each pair of primary sprockets; d) one or more pairs of proximal and distal secondary sprockets mounted on the frame; e) a secondary endless-chain digging assembly engaged with and circulating around each pair of secondary sprockets. The primary chains are substantially wider than the secondary chains, and the diameters and positions of the sprockets may be such that each of the secondary chains cuts more deeply into the ground formation than the primary chains, thereby producing a narrow relief slot corresponding to each secondary chain. The primary chains are driven in a forward chain direction, so that disintegrated material is removed from the trench by the motion of the primary chains. The secondary chains may be driven in a forward or a reverse chain direction at about one to eight times the linear speed of the primary chains. If operated in the reverse chain direction, the disintegrated material produced by the secondary chains may be deposited within the trench by the motion of the secondary chains. The material thus deposited may serve as a support bed for whatever structure is to be subsequently placed within the trench.

Patent CA-2379483-C (CA)
Inventor: COTTER DAVID
IPC: H04B10/299
Filed: 2000-07-19
Granted: 2007-12-04
Abstract: An optical regenerator suitable for use with optical signals has two stages.  An incoming optical signal to be regenerated passes first through a data division stage. This divides the optical data stream into a number of data streams at a bit rate lower than the original optical signal. These data streams then pass to a regeneration stage. In the regeneration stage, there are a number of optical gates. Each gate receives one of the optical data streams at its control input. An optical clock stream at the lower or at a multiple thereof passes through the optical gates. The output of these optical gates are connected in common to the optical output of the regenerator and provide a bit-interleaved regenerated optical data stream at the output.

IPC: G06F19/00
Filed: 2001-02-13
Granted: 2008-07-15
Abstract: An elapsed time clock (31) is incorporated into a part call tag for requesting replenishment of components used by workstations of a manufacturing facility. One or more transmission readers spatially distributed around the manufacturing facility detect a part call signal transmitted from the part call tag. A reader output processing subsystem processes part call signals detected by at least one of the tag transmission readers to recover information contained in the part call signal. A management processor associates the recovered information with a respective workstation, and what component is to be replenished. The elapsed time clock (31) is reset (33) when the part call tag is operated to transmit a part call signal, and thereby serves as a call tag 'stop watch' - informing workstation personnel of the length of time that has elapsed since the last part call transmission from that tag.

Patent CA-2407952-C (CA)
Inventor: SCHENSE JASON C
IPC: C07K14/745

Granted: 2007-08-07
Abstract: Dans la présente invention, des protéines sont incorporées dans des matrices de protéines ou de polysaccharides destinées à être utilisées pour réparer, régénérer et/ou remodeler des tissus ou pour apporter des médicaments. Les protéines peuvent être incorporées de manière à ce qu'elles soient libérées par la décomposition de la matrice par une action enzymatique et/ou par diffusion. Comme le démontrent les exemples, un procédé consiste à lier l'héparine à la matrice par des procédés de liaison covalente ou non covalente afin de former une matrice à l'héparine. L'héparine lie ensuite de manière non covalente des facteurs de croissance liant l'héparine à la matrice protéique. Dans une forme de réalisation, on peut construire une protéine hybride qui contient une région de réticulation telle qu'un substrat de facteur XIIIa et la séquence de protéines natives. Il est particulièrement intéressant d'incorporer des liaisons dégradables entre la matrice et les facteurs bioactifs lorsqu'un apport de médicament de longue durée est souhaité, par exemple en cas de régénération nerveuse lorsqu'il est souhaitable de varier la vitesse de libération du médicament dans l'espace en fonction de la régénération, par exemple, rapidement à proximité de l'interface avec les tissus vivants et plus lentement dans une zone plus profonde de la région de la lésion ou de la blessure. D'autres avantages concernent la dose totale de médicament qui est plus faible dans le système d'apport et la régulation dans l'espace de la libération qui permet de libérer un plus grand pourcentage du médicament au moment où l'activité cellulaire est maximale.
