Title: Apparatus for controlling pulley side-pressure of continuously variable transmission in vehicle having function of stopping engine idling
Inventor: EGUCHI TAKAHIRO
IPC: F16H9/18
Filed: 2000-07-05
Abstract: In an apparatus for controlling a pulley side--pressure of a belt type continuously variable transmission mechanism (5) provided, in series with a starting clutch (7), in a transmission of a vehicle having a function of stopping engine idling so that an engine (1) is automatically stopped, if the vehicle start-up is controlled from the state of engine stopping in an ordinary way in which the pulley side-pressure is determined by that belt transmission torque (TQBLTNOM) corresponding to an output torque of the engine (1) which is obtained by the rotational speed and the negative suction pressure of the engine (1), the pulley side--pressure becomes excessive by wrong judgement that the engine output torque is large, because the negative suction pressure is small at the beginning of the engine starting. The durability then deteriorates and the specific fuel consumption becomes poor. As a solution, at a vehicle start-up from the state of engine stopping, a belt transmission torque (TQBLTSC) corresponding to that transmission torque (TQSCX) of the starting clutch (7) which is obtained by the engaging force of the starting clutch (7) is compared with a belt transmission torque (TQBLTNORM) corresponding to the engine output. The pulley side-pressure (PDR, PDN) is each controlled based on that transmission torque (TQDR) of the drive pulley (50) corresponding to the smaller belt transmission torque and on the transmission torque (TQDN) of the driven pulley (51). 24

Abstract: An electric motor driven bypass type vacuum cleaner apparatus, particularly adapted for wet/dry debris collection includes an open top debris collection tank having opposed integrally formed cup-shaped feet for supporting said apparatus in a, stable position on a support surface. The tank includes a recess in a sidewall and a bottom wall for receiving a conduit member which may be interchangeably used as a connector for connecting a flexible vacuum hose to the tank and as a blower discharge nozzle. A flexible vacuum pickup hose is connected to the conduit member generally at the bottom side of the debris collection tank and,  in a stored position on the apparatus, is trained through a recess in the bottom wall of the tank and over the top of a motor housing and shroud assembly to a connection point in one of the support feet adjacent the conduit member. The vacuum hose, when stored, is retained in a recess in the shroud which also serves as a carrying handle for the apparatus. The vacuum impeller drive motor is mounted in a housing assembly including separable tank cover, motor base and motor housing members. The motor base and tank cover form a discharge volute chamber for the vacuum impeller. Motor cooling air inlet and discharge passages are formed by and between the motor housing member and the shroud.

Inventor: VANDERHYDE DANIEL W
IPC: B30B9/30
Filed: 2000-09-06
Abstract: A baling machine for baling tobacco and other materials. The baling machine includes a bale chamber that includes a bottom, opposed ends, a ram assembly, and a pair of opposed side and top assemblies. Each side and top assembly is pivotally mounted adjacent the floor of the bale chamber and movable from a closed position to an open position. In the closed position each side and top assembly extends around the bale chamber and forms a part thereof. In the open position, each side and top assembly extends outwardly from the bale chamber and effectively leaves the bale chamber open from the top, thereby enabling tobacco to be fed into the bale chamber from the top. Once the bale chamber has been filled, the side and top assemblies are closed and the ram assembly pushed through the bale chamber causing the tobacco therein to be compressed and formed into a bale. Thereafter, the bale is either ejected or removed from the bale chamber.

Patent CA-2332405-A1 (CA)
Title: Communication system
Inventor: OSHIMA MITSUAKI
IPC: H04N21/647
Filed: 1993-03-25
Abstract: At the transmitter side, carrier waves are modulated according to an input signal for producing relevant signal points in a signal space diagram. The input signal is divided into, two, first and second, data streams. The signal points are divided into signal point groups to which data of the first data stream are assigned. Also, data of the second data stream are assigned to the signal points of each signal point group. A difference in the transmission error rate between first and second data streams is developed by shifting the signal points to other positions in the space diagram. At the receiver side, the first and/or second data streams can be reconstructed from a received signal. In TV broadcast service, a TV signal is divided by a transmitter into, low and high, frequency band components which are designated as a first and a second data stream respectively. Upon receiving the TV signal, a receiver can reproduce only the low frequency band component or both the low and high frequency band components, depending on its capability.

Title: Steam control apparatus for turbine
Inventor: NAGATA SHOUICHI
IPC: F02C7/18
Filed: 2001-04-17
Abstract: The temperature and flow rate of steam introduced to a gas turbine and a combustor is controlled properly through mixing intermediate-pressure steam and high-pressure steam. Thus, two different requirements; i.e., adjustment of steam temperature and securing of a sufficient steam flow rate, can be satisfied simultaneously. As a result, it becomes possible to simultaneously achieve control of the clearance of the blade ring of the gas turbine by means of steam and cooling of the combustor by means of steam.

Title: Integrated optical waveguide chemical sensor with bragg grating
Inventor: SHEARD STEPHEN JOHN
IPC: G02B6/124
Filed: 1999-10-04
Abstract: In an optical device including a Bragg grating (4), such as a gas or vapour sensor, a planar optical waveguide layer (2) is carried on a substrate (1) a nd has a cladding layer (3). Light from a source (7) is transmitted via an inpu t fibre (6) along the waveguide layer (2) to be incident on the Bragg grating (4) at an angle which results in Bragg scattering from it. The scattered radiation is monitored to determine the concentration of the gas to which th e sensor is exposed, the effective index of the waveguide (2) varying with changes in concentration of the gas. To obtain high sensitivity, edge surfac e (5) of the substrate (1) and waveguide layer (2) is curved, permitting the input fibre (6) to be adjusted in position to satisfy the Bragg angle at the  grating (4) for a particular device geometry. Thus variations in dimensions of the device because of manufacturing tolerances may be accommodated. Also, th e same device may be used with different light sources by suitably positionnin g the input fibre (6) relative to the grating (4).

Filed: 1999-10-08
Abstract: Cette invention se rapporte à un appareil et à des procédés servant à faciliter le passage retour des extrémités lacérées d'un tendon dans et/ou à travers une gaine associée. Ce procédé est souvent nécessaire pour permettre la réparation complète d'un tendon, lorsque les extrémités lacérées d'un tendon se sont rétractées de leur site de lacération dans la gaine. Ce procédé consiste à appliquer des tubes élastomères respectifs sur les extrémités lacérées du tendon. Chaque tube élastomère est de préférence fabriqué en caoutchouc élastique mince. Ce tube élastomère empêche également l'effilage et l'accrochage des extrémités lacérées respectives lors de leur passage dans et à travers la gaine. Des fils multiples sont de préférence associés au tube élastomère. Un applicateur est prévu pour faire coulisser un tube élastomère respectif sur chaque extrémité lacérée du tendon. Chaque tube élastomère est placé sur l'extrémité lacérée respective du tendon, par traction sur les fils associés. Après application du tube, l'applicateur est retiré. Les fils, ainsi que les brins de suture préalablement placés dans l'extrémité du tendon, sont ensuite utilisés pour tirer le tube et l'extrémité lacérée dans et à travers la gaine. Une fois que le tendon est passé à travers sa gaine, on retire le tube en le retirant de l'extrémité du tendon à l'aide des fils.
