Abstract: The present invention is a torso protection system having braided tubes (131) that inflate upon side or oblique impact to protect the torso of a seated vehicle occupant. Prior to inflation, the braided tubes (131) are mounted in the undeployed state along both sides of the occupant's seat (136, 137). When an impact is detected, a gas generator (133) generates gas, inflating the braided tubes (131). As the braided tubes inflate, their diameters increase and their lengths decrease substantially.     The braided tubes (131) then pull out of their storage locations and from bolsters on either side of the seated occupant. The inflated tubes (131) prevent the torso of the occupant from directly colliding with interior side structures of the vehicle and restrict the lateral motion of the occupant.

Abstract: Les procédés et l'appareil selon la présente invention permettent la création d'une poche corporelle (3) stable au moyen de plusieurs feuilles biocompatibles (10, 14) ou au moyen d'une seule feuille biocompatible (10) que l'on place soit pour créer une poche corporelle stable définissant un espace potentiel ou un espace réel. Lesdites feuilles (10, 14) sont pourvues d'une surface (16, 12) dans laquelle le tissu peut se développer et ainsi bloquer, de façon stable, la feuille (10, 14) dans la position désirée. L'autre surface (18, 20) n'adhère pas, de sorte qu'une adhérence à une surface en vis-à-vis n'est pas possible, ce qui permet d'avoir une poche corporelle stable. En outre, on peut former une poche corporelle stable au moyen d'une feuille ou de feuilles biocompatibles (10, 14) présentant une surface (12, 16) pouvant être, de façon sélective, pénétrée par les tissus en développement, de sorte que certaines parties de la surface pénètrent dans le tissu environnant et d'autres parties de la surface (18, 20) n'adhèrent pas au tissu environnant. Ainsi, l'appareil formant la poche corporelle stable est pourvu de parties superficielles souples. Selon l'invention, on peut également former des canaux stables d'accès à une cavité corporelle. De tels canaux constituent des moyens stables permettant la communication entre l'extérieur du corps et une poche corporelle interne naturelle ou créée. La présente invention concerne également un procédé permettant de former une poche corporelle stable par introduction d'un fluide sous pression dans l'espace où l'on veut créer une poche corporelle.

Abstract: Hydrostatic transmission comprises a radial piston pump assembly having an axis of rotation and a gear motor. A hydrostatic fluid pathway extends between the gear motor and the radial piston pump such that the gear motor is fluidly coupled to the radial piston pump, wherein the gear motor comprises at least one gear which is capable of being rotatably driven by a fluid being transported along the fluid pathway. Preferably, a piston guide retains the piston heads against the corresponding slippers without requiring any kind of direct mechanical linkage to maintain such coupling. The present invention further provides a hydraulic shockabsorber which absorbs pressure pulses generated by a rotating rotary cylinder block of a radial piston assembly, which may be either a pump or a motor.

Title: Drying sand to prevent freezing without the use of salt
Inventor: HADIKEN LAWRENCE
IPC: F26B5/00
Filed: 1998-10-09
Granted: 2001-02-13
Abstract: A method for supplying dry sand for spreading on road surfaces in freezing temperatures in a condition in which the sand remains fluid in freezing temperatures without the addition of salt includes the steps of drying the sand by providing a naturally occurring bed of the sand having an upper surface of the bed exposed to sunlight; planting on the upper surface a covering crop of a type such as alfalfa having deep roots which extend through the whole bed up to thirty feet deep in search of a water table below the bed and growing the crop for a period of time sufficient to allow the roots to penetrate the bed and to extract moisture from the bed to dry the sand in the bed. The dry sand is extracted from the bed and stored temporarily in a closed storage which prevents the re-introduction of moisture for subsequent use on road surfaces without the necessity of salt to keep the sand fluid for spreading.

Abstract: In a dispatch system, power of the forward link broadcast channel transmitted from a base station is controlled such that the power level is the minimum necessary and such that transmission of the forward link broadcast channel is terminated if no remote unit (10) is Located within the coverage area of the base station (32). In addition to transmitting a forward link broadcast signal, the base station monitors an access channel.      A first remote unit (10) in the base station coverage area receives and decodes the forward link broadcast signal. The first remote unit (10) determines a signal quality of said forward link broadcast signal. If the signal quality is unacceptable, the remote unit transmits a power request access message. The base station responds to the request by increasing the transmission power of forward link broadcast channel (70). If no requests are received at the base station, the forward link broadcast channel is slowly decreased to a minimum (54). Transmission of the forward link broadcast channel may be terminated completely (58).
