Title: Contacting system for electrical devices
Inventor: JOHNSON DAVID A
IPC: H01R12/16
Filed: 1995-05-04
Granted: 2000-06-27
Abstract: A connector for electrically interconnecting a lead of a device to a terminal spaced at a distance from the lead. The apparatus includes a conductive element comprising a first contact, a shoulder, and a second contact. The first contact is attached to the shoulder and extends upward therefrom, and the second contact is attached to the shoulder and extends downward therefrom. The first contact is electrically coupled to the lead of the device when the lead of the device is brought into engagement with the first contact. The second contact is electrically coupled to the terminal. A support member is positioned below the shoulder of the conductive element and a resilient biasing means comprising an elastomeric material is positioned between the shoulder of the conductive element and the support member. The resilient biasing means resiliently biases the conductive element in an original position. When a downward force is applied to the conductive element, however, the resilient biasing means may be overcome thereby allowing the conductive element to move in a downward direction in response to the downward force. The resilient biasing means returns the conductive element to the original position when the downward force is removed.

Abstract: A self-timed interface (STI) in which a clock signal clocks bit serial data onto a parallel, electrically conductive bus and the clock signal is transmitted on a separate line of the bus. The received data on each line of the bus is individually phase aligned with the clock signal. The received clock signal is used to define boundary edges of a data bit cell individually for each line and the data on each line of the bus is individually phase adjusted so that, for example, a data transition position is in the center of the cell.

Title: Production of human recombinant collagen in the milk of transgenic animals
Inventor: BERG RICHARD A
IPC: C12N5/10
Filed: 1994-01-19
Granted: 2004-04-27
Abstract: Production of human procollagen or collagen in cells which ordinarily do not produce these molecules is effected by constructing expression systems compatible with mammary glands of non-human mamals. For example, expression systems can be microinjected into fertilized oocytes and reimplanted in foster mothers and carried to term in order to obtain transgenic non-human mammals capable of producing milk containing recombinant human procollagen or collagen. Human procollagen or collagen produced in this manner can be made of a single collagen type uncontaminated by other human or non-human collagens.

Title: Protective helmet
Inventor: EASLEY JAMES B
IPC: A42B3/04
Filed: 1995-07-31
Granted: 2003-09-23
Abstract: A protective helmet suitable for safe use by a person having long hair is disclosed.  The helmet includes an outer dome-shaped shell of impact-resistant material configured to fit on the head of a wearer.  A liner affixed to the inside of the shell snugly positions the helmet on the head and dissipates impact forces received by the outer shell.  A hair-entraining passage formed in the rear portion of the helmet is sized to enable the wearer's hair to be gathered and controllably guided thereby.  The passage may be defined by a bulge in the helmet shell or by an aperture formed therethrough.  The aperture is sized small enough to prevent harmful impact penetration of an object such as a ball, hockey puck or the like with the wearer's head.

Abstract: A crawler-belt vehicle is a half crawler vehicle having front wheels furnished with tires, and crawlers on a rear wheel side composed of crawler belts extending between intermediate wheels and rear wheels. The front wheels are larger in diameter than the intermediate wheels and the rear wheels and, hence, have a large ground-contact surface area. Thus, while the vehicle is running on snow, the front wheels are not apt to sink in the snow to a greater extent with the result that the turning characteristic and breakthrough characteristic of the vehicle can be improved. The intermediate wheels may be set to toe in so as to prevent detachment of the crawler belts which would otherwise occur when the sub-beams are slightly flexed or deformed in a lateral outward direction under loads applied thereto while the vehicle is traveling at high speeds on the snow. In order to reduce side slips of the crawler belts, an intermediate line extending parallel to, and passing substantially intermediately between, an axle centerline of the intermediate wheels and an axle centerline of the rear wheels is arranged to meet with a turning center of the right front wheel, and a turning center of the left front wheel at the same point.~~

Title: Mesh interconnected array in a fault-tolerant computer system
Inventor: NORDSIECK ARNOLD W
IPC: G06F11/00
Filed: 1997-06-03
Granted: 2003-11-25
Abstract: This invention relates to fault-tolerant computer systems. Bus interface units (BIUs) perform fault detection, identification, and reconfiguration for all information transfers between redundant central processing units (CPUs) and memory or input/output (I/O) in a mesh interconnected array of a computer system. Errors are detected by self-checking within the BIUs, signal parity checks by the BIUs, cross channel comparisons, and mesh transaction assessments. If self implicating errors are detected, the corresponding BIU is shut down, BIU configuration vectors are asserted onto the mesh and a consensus configuration vector is generated. If synchronization or memory bus errors are detected, corresponding error messages are asserted on the mesh and a reconfiguration algorithm is performed in order to generate a consensus configuration vector. Fault identification and mesh reconfiguration for the mesh is performed such that no faulty unit remains active in decision making after reconfiguration, and the number of good units isolated during reconfiguration is minimized.

Abstract: A method of wood waste disposal which regulates factors such as the amount of wood residue being fed to an incinerator at any given time so that the overall combustion level of wood residue in the incinerator is maintained approxi-mately constant over time. The wood residue is separated into at least two frac-tions, the first fraction being directed to a storage bin for later use as required, and the second fraction being directed to the incinerator. During periods of slack feed of the second fraction to the incinerator, portions of the first fraction, as required, are directed to the incinerator as make-up, in order to maintain the overall combus-tion level in the incinerator approximately constant.
