Abstract: A mechanical disconnection mechanism for a hydrostatic transmission. The output shaft of the hydrostatic transmission is divided into a drive portion and a driven portion, with both the drive portion and the driven portion being provided with external splines or gears. To connect the drive portion to the driven portion, a splined sleeve is positioned to engage the splines of both the driven portion and the drive portion such that rotation of the drive portion rotates the driven portion. To disconnect the drive portion from the driven portion, the splined sleeve is positioned to engage only one of the drive portion and the driven portion. In the disconnected position, the implement may be manually pushed without reverse driving the hydraulic unit of the transmission to thereby allow for relatively easy movement. A brake is mounted about the driven portion of the output shaft to enable the vehicle to be stopped regardless of the position of the splined sleeve.

Abstract: A device is needed that is usable for repairing both bulls-eye cracks and elongate cracks in a laminated glass plate, e.g. a vehicle windshield. For a bulls-eye crack, the device should be capable of drawing air from the crack to be replaced with liquid filler. For an elongate crack, the device should be moveable along the length of the crack while consistently dispensing liquid filler. The present device provides a piston-cylinder combination for both withdrawing air and dispensing liquid filler and including control features that convert between linear actuation of the piston in the cylinder and screw-type actuation of the piston in the cylinder.

Title: Automatic train serialization
Inventor: KNIGHT DOUGLAS G
IPC: B61L15/00
Filed: 1997-01-09
Granted: 2002-03-19
Abstract: A method of serialization including providing a parameter which varies along the length of the train and transmitting a synchronization signal along the length of the train to the local nodes at each car. The parameter is measured at each node with respect to the occurrence of the synchronization signal at the node.  Serialization of the cars is then performed as a function of the measured parameters.  One method is to provide the parameters by transmitting a serial signal which propagates through the train at a slower rate  than  the  synchronization  signal  and  then measuring the difference in time between the receipt of the synchronization and the serial signal at each node.  A second method of implementation is to create a pressure gradient in the brake pipe along the length of the train.  The brake pipe pressure or flow rate is read at each node upon receipt of the synchronization signal.  As a third alternative, an electric load is provided at each node in parallel to a trainline running through the train.  The current or voltage of the trainline at each node is then measured upon receipt of the synchronization signal.

Abstract: La présente invention est une méthode servant à dissimuler des messages dans l'espace des fréquences utilisé pour des informations. Elle vise à procurer une méthode de dissimulation de données fortement protégée contre les extractions ou les modifications qui maintient cette dissimulation de façon efficace même en cas de traitement des signaux au moyen d'un filtre fréquentiel. Pour dissimuler un message (m) dans des informations (M), on effectue des transformations de fréquence du message (m) et des informations (M) et l'on obtient les spectres de fréquence f2 et f1 correspondants. Ensuite, on choisit dans le spectre de fréquence f2 du message (m), comme région de base B, une région contenant des fréquences représentatives des caractéristiques du message (m) dans l'espace réel. On crée ensuite n copies de la région de base B que l'on disperse dans l'espace des fréquences. On crée également un spectre de fréquence f3 comme information intermédiaire. Finalement, on additionne les spectres de fréquence f3 et f et on peut dissimuler le message (m) dans les informations (M) en effectuant la transformation de fréquence inverse sur le résultat de l'addition.

Title: Detection of nucleic acids by fluorescence quenching
Inventor: VONK GLENN P
IPC: C12Q1/68
Filed: 1998-05-04
Granted: 2002-04-23
Abstract: Single-stranded signal primers are modified by linkage to two dyes which form a donor/acceptor dye pair. The two dyes are positioned in sufficiently close spatial proximity on the signal primer that the fluorescence of the first dye is quenched by the second dye. The signal primer may further comprise a restriction endonuclease recognition site (RERS) between the two dyes. As the signal primer is initially single-stranded and remains single-stranded in the absence of target, the restriction endonuclease recognition site is not cleavable or nickable by the restriction endonuclease. In the presence of target, however, signal primer and the restriction endonuclease recognition site are rendered double-stranded and cleavable or nickable by the restriction endonuclease. Cleavage or nicking separates the two dyes and a change in fluorescence due to decreased quenching is detected as an indication of the presence of the target sequence or of target sequence amplification.

Abstract: A golf club commonly referred to as a "driver" includes a head made of titanium and a hosel made of plastic. The head includes a hollow body, and the hosel has a lower portion inserted into a bore in the head and an upper portion extending upwardly from a top wall of the hollow body. The bore has an open top end that is substantially flush with the body top wall and a closed bottom end that is spaced from a bottom wall of the hollow body. A passage extends through the upper and lower portions of the hosel and receives a tip end of a shaft that is preferably made of graphite. Since the hosel is made of softer material than the head, the hosel has a cushioning effect on the shaft which reduces the amount of vibration transmitted to the shaft. The hosel lower portion has an irregular outside shape and the bore in the head has a complementary irregular inside shape so that the hosel may be inserted into the bore in only one orientation to ensure exact alignment of the shaft relative to the head.

Abstract: A digital carrier recovery system includes at least two modes of operation, namely, an acquisition mode and a tracking mode. The bandwidth of the carrier recovery loop filter is different for the acquisition mode and the tracking mode. In the acquisition mode, the digital phase-locked loop seeks and locks to the long term frequency offset of the received carrier signal. In the tracking mode, the digital phase-locked loop tracks the instantaneous variations in the carrier phase.  Switching between the acquisition mode and the tracking mode is realized digitally, and includes programmable hysteresis, resulting in optimal performance in the presence of signals having high levels of phase noise (jitter). More specifically, the carrier recovery loop filter "locks" to the pilot signal of an incoming signal, e.g., a vestigial side band (VSB) video signal, by employing a so-called digital vector tracking phase-locked loop that demodulates the VSB signal. The digital vector tracking phase-locked loop includes a complex filter, i. e., a so-called vector tracking filter, that very quickly locks to the pilot signal of the passband VSB signal and once locked to the pilot signal, switches to the tracking mode that provides significantly better tracking of phase noise. The demodulation is achieved by employing a complex multiplication of the incoming signal with a complex exponential sequence to obtain an in-phase (I-phase) component and a quadrature-phase (Q-phase) component. The complex exponential sequence is generated, in one embodiment, by employing a SIN/COS look up table that is driven by a phase difference signal generated by the digital vector tracking phase-locked loop. A residual direct current (dc) component in the I-phase component caused by the pilot signal is removed, resulting in a baseband I/Q signal. A technical advantage of this carrier recovery invention is that the bandwidth of the phase-locked loop filter can be different for the acquisition mode and the tracking mode. This allows for optimal performance in both the acquisition and tracking modes of operation.
