Title: Embryogenese et regeneration de plantes a partir de microspores
Inventor: SIMION ECATERINA
IPC: C12N15/82
Filed: 2000-12-07
Abstract: L'invention concerne un procédé d'embryogenèse et un procédé de régénération de plantes. Des segments de plantes contenant des microspores de plantes donatrices sont ramassés puis incubés dans des conditions de pré-traitement afin de maintenir les microspores en phase G1 de cycle cellulaire uninucléé. Les conditions de pré-traitement comprennent de l'eau froide ou une solution aqueuse d'environ 0,2 à environ 1,0 mol/litre d'alcool, par exemple du mannitol. Les microspores sont isolés du segment de la plante et l'embryogenèse des microspores est induite dans un milieu d'induction, produisant ainsi des embryons. Les plantes vertes peuvent être régénérées à partir des embryons produits. On peut ajouter au milieu d'induction une co-culture de protéines d'arabinogalactane, d'auxines et d'ovaires afin d'améliorer l'embryogenèse à partir des microspores.

Abstract: An ultrasonic distance measuring system (10) for monitoring railroad car loads. The system includes an ultra sonic transducer (20), a pulse generation and detection circuit (22) and a measurement circuit (24). The transducer (20) produces a transmitted ultrasonic pulse beam (14, PT) to be directed at a load (12) in a railroad car (8) and receives a return pulse beam (PR) from the load (12). The pulse generation and detection circuit (22) is coupled to the transducer (20) and causes the transducer (20) to produce the transmitted pulse beam (14, PT). A return pulse beam (PR) is detected by the pulse generation and detection circuit (22). The measurement circuit (24) is coupled to the pulse generation and detection circuit (22) and generates a measurement signal representative of the load (12) as a function of the time delay between the transmitted and return pulse beams (PT, PR).

Title: Locomotive hand brake alarm
Inventor: NAGLE JAN ALAN
IPC: B61H13/02
Filed: 2002-09-12
Abstract: A hand brake system (40) for a rail vehicle providing a hand brake position alarm (76) before a train is moved with a hand brake not fully released. A switch (56) detects the position of a hand brake drive chain (18) to provide a brake engaged signal (60). The weight of the drive chain is supported through a load path that bypasses the switch. A master controller reverser handle position detector (74) provides a reverser handle position signal (72) when the reverser handle is moved out of neutral in preparation for providing power to the locomotive drive motors (15). A relay (70) is used to actuate the multiunit wheel slip indicator (54) and the general alarm bell (52) in every locomotive of the train consist when the brake engaged signal is coincident with the master controller reverser handle position signal. This combination of alarms, which normally indicates a locked axle when the train is above a predetermined speed, is interpreted as a hand brake position alarm when the train is at rest.

Title: Improved methods for detecting leaks in pressurized piping with a pressure measurement system
Inventor: MARESCA JOSEPH M JR
IPC: G01M3/26
Filed: 2001-05-02
Abstract: A method of detecting a leak in a pipeline system, wherein a measurement is performed to determine the difference in the rate of change of pressure due to a leak between one pressure level and at least one other pressure level, after compensation has been made for thermally induced changes in the pressure in a pressurized pipeline system, including the steps of pressurizing the pipeline system to a first pressure level, and measuring the changes in pressure in the pipeline system that occur over a first measurement period; and pressurizing the pipeline system to at least a second pressure level, and measuring the changes in pressure in the pipeline system that occur over at least a second measurement period. A  computation is then performed of the difference in the temperature compensated rate of change of pressure between one pressure level and at least one other pressure level from the measured pressure data at the pressure levels, including a correction for the thermally induced non-linear changes of pressure rate of change of pressure between the pressure levels is computed from the rate of change of pressure measured during the measurement periods (first derivative of the pressure data or rate of change of pressure) and higher order derivatives of the pressure data.

Abstract: A selective encryption encoder consistent with certain embodiments of the invention has vertical and/or horizontal stripes encrypted. In one embodiment, packets are examined in the digital video signal to identify a specified packet type, the specified packet type being packets carrying data representing a video slice wherein the video slice contains a larger amount of data than a threshold (or a subsequent slice). The packets identified as being of the specified packet type are encrypted using a first encryption method to produce first encrypted packets. These first encrypted packets are then used to replace the unencrypted packets in the digital video signal to produce a partially encrypted video signal. The packets of the specified type,can also be multiple encrypted and replaced in the data stream to produce a multiple encrypted video data stream.
