Patent CA-2138301-A1 (CA)
Inventor: OTTESEN HAL H
IPC: G11B7/0037
Filed: 1994-12-15
Abstract: A disk drive stores multimedia data in long spiral data tracks. The tracks on opposite surfaces of the disk spiral in opposite directions, so that a track on one surface can be read as the actuator sweeps in, and a track on the opposite surface can be read as the actuator sweeps out. Because the actuator only follows spiral tracks without performing long seek operations, the actuator motor can be reduced in size and stresses on actuator bearings and other parts are reduced. Additionally, due to reduced disturbances associated with seeks, it is possible to follow tracks more closely and therefore reduce the width of individual tracks. Further cost reductions are accomplished by spinning the disks at a slower speed and reducing the size of the spin motor accordingly. Finally, data density can be increased simply because multimedia data does not require the same low error rate as conventional data. Preferably, a group of disk drives optimized for multimedia data is used to form a video-on-demand system. Compressed, interleaved portions of a video presentation, such as a motion picture, are stored in blocks on the spiral tracks. The drives read the blocks on one spiral track at a time from beginning to end, placing the data from these blocks in a set of buffers corresponding to different short time intervals. Video signals are output from the buffers. Any short time interval of the presentation can be accessed on demand by switching to the appropriate buffer.

Title: Method for forming articles of reinforced composite material
Inventor: WOLD TED H
IPC: B27N1/00
Filed: 1994-09-20
Abstract: A method for producing articles comprised of reinforced composite materials including primarily wood or cellulosic fiber and plastic is disclosed. The wood fibers are comminuted to substantially a specific thickness and classified according to length. Plastic is comminuted (28) and mixed with wood fibers (32) to form a reinforced composite mixture in predetermined ratios.  The composite materials form the main structural or bonding components of the finished article. Other chemicals, such as a coupler (33) can be added, as can other structural components, such as fiberglass (45). The mixture is deposited onto a mold (35) when forming articles having deep drawn portions, and subjected to sufficient temperature and pressure to cause the composite mixture substantially to assume the mold form. The process variables disclosed can be selectively modified to produce predetermined physical characteristics in the finished article, such as strength, thickness or prestressed qualities.  An article produced by the above process also is disclosed.

Patent CA-2167621-A1 (CA)
Title: Carrier conveyor system
Inventor: HOOPER RICHARD GRANT
IPC: B62D65/18
Filed: 1996-01-19
Abstract: A carrier conveyor system wherein carriers are disengaged from the main conveyor in advance of a work station and re-engaged beyond the work station and a transfer conveyor is positioned such that it receives the carriers as they are disengaged, transfers them as required to the work station, removes them from the work station after the work is performed and returns them to the main conveyor.          The transfer conveyor comprises a plurality of transfer assemblies arranged in succession in tandem array along the carrier travel path, and each consisting of right and left hand mirror imaged modules which are mechanically drivingly cross-connected by means of a gear belted underhung jack shaft.  These right and left modules are positioned along each side of the path of the carriers from the area where the carriers are disengaged from the conveyor through the work station and to the area where the carriers are re-engaged with the conveyor.  Each transfer module consists of a narrow longitudinally extending carrier transport belt, driven by a variable speed AC or DC motor coupled through a reducer to a belt head pulley, the upper carrier transport run being supported by either wheels, a slider bed or a combination of the two.  The belts are driven continuously when it is desired such that the carrier is moved by each transfer assembly to the succeeding transfer assembly or position.   The number of transfer assemblies is such that there will be sufficient time at the work station to perform the function desired and at the same time there will always be a carrier ready for re-engagement with the conveyor thereby insuring that there will be a carrier at each job space on the main conveyor in the remainder of the conveyor system.

Title: Sensor with laterally-supported beam contacts
Inventor: MALESKO MICHAEL W
IPC: G01P15/135
Filed: 1995-07-18
Abstract: An improved acceleration sensor (10) includes a housing (12) having an internal passage (14) defined therein, a sensing mass (18) located within the passage which moves from a first position within the passage towards a second position therein in response to acceleration inputs to the sensor housing, and a pair of electrical contacts (22) projecting into the passage so as to be bridged by the sensing mass when it reaches its second position within the passage, thereby closing an electrical circuit.  The supported end (28) of each of the contacts includes diametrical arms (32) which are themselves secured to the housing only at their outboard ends (36).  The arms are thus free to rotate elastically when the sensing mass deflects the contact's cantilevered free end (30), thereby permitting greater elastic travel of the contact's free end, with its enhanced reliability and an attendant increase in contact dwell.

Inventor: GILHOUSEN KLEIN S
IPC: H04B7/005
Filed: 1994-10-28
Abstract: Plusieurs procédés permettent de réaliser un transfert sans interruption, avec plus ou moins d'anticipation, de façon à améliorer le fonctionnement d'un système. Un premier procédé consiste à retarder l'opération de transfert moins brusque. Un second procédé se base sur la réduction de la puissance des émissions à partir du secteur où la puissance de signal est la plus faible. Un troisième procédé consiste à éliminer les émissions provenant du secteur où la puissance de signal est la plus faible. Un quatrième procédé n'ajoute une nouvelle station de base ou un nouveau secteur que lorsque l'unité mobile a besoin de davantage de puissance pour fonctionner correctement. Dans ces quatre procédés, la démodulation de liaison d'amont dans chaque secteur peut se poursuivre avec ou sans transmission sur la liaison d'aval. Dans les quatre procédés, le fonctionnement peut se baser sur l'intensité du signal de la liaison d'amont ou de la liaison d'aval. Il est aussi possible d'associer deux ou plusieurs de ces procédés pour créer un procédé hybride.

Abstract: This invention pertains to the discovery that condensation polymers of an aldehyde and aromatic sulfonic acids and fractions thereof, such as formaldehyde naphthalenesulfonic acid condensation polymers, can abrogate HIV gp120 binding to CD4, as demonstrated in CD4/gp120 binding assays. In addition to gp120 binding inhibition, the compounds have been shown to inhibit HIV-induced syncytia formation and infectivity of CD4 cells. The use of this compound has been shown to be non-cytotoxic and non-inhibitory to antigen induced T lymphocyte proliferation. Based on these findings, these compounds can be used as a therapeutic agent for the treatment of acquired immunodeficiency syndrome (AIDS), as well as AIDS-related complex (ARC), AIDS-related dementia and non-symptomatic HIV infection. The compounds can also be used to treat blood preparations.
