Title: Thermally convertible lithographic printing precursor and master comprising an organic acid
Inventor: GOODIN JONATHAN W
IPC: B41C1/10
Filed: 2002-07-23
Abstract: A thermally convertible lithographic printing precursor comprises a lithographic base with an imageable coating. The imageable medium of the coating comprises uncoalesced particles of a hydrophobic thermoplastic polymer, a converter substance capable of converting radiation into heat, and an organic acid. A lithographic printing master is made by image-wise or information-wise exposing the precursor to radiation and then developing the precursor with an aqueous medium to remove the unirradiated parts of the coating.

Abstract: L'invention concerne un appareil de moulage par injection, qui comprend un premier élément de tige de coulée (36) comportant un premier canal de coulée (34) pour recevoir un flux de matière fondue d'un matériau moulable sous pression. Un second élément de tige de coulée (38) comporte un second canal de coulée (39) pour recevoir sélectivement le flux de matière fondue du premier canal de coulée. Un collecteur (50) présente un canal de collecteur pour recevoir le flux de matière fondue du second canal de coulée (30) et le transférer à un canal d'une buse (44). Une cavité de moulage (30,32) reçoit le flux de matière fondue de la buse (44). Le canal de la buse communique avec la cavité de moulage par une entrée de moulage (46). Un premier ensemble d'entrée (180) est couplé à un orifice de sortie du premier élément de tige de coulée pour limiter sélectivement l'écoulement de la matière fondue provenant du premier canal de coulée. Le premier ensemble d'entrée peut être déplacé pour limiter l'écoulement lorsque l'écoulement de la matière fondue entre le premier canal de coulée et le second canal de coulée est interrompu.

Title: Precision medium handling system and method for a recorder
Inventor: MOULIN MICHEL
IPC: B65H23/032
Filed: 1990-01-08
Abstract: ABSTRACT         Accurate control of the lateral position and spacing of a photosensitive medium is provided for recording a succession of lines representing graphic images or portions thereof, without mechanical edge guides.  The apparatus includes an optical edge detector, a film drive assembly having two independently-controlled feed units, and a deviation correction means to correct the position prior to actual printing of images.        Preferably, a triangulation method is used to electronically correct the drive path of the medium.  Error-correction is obtained by the combined action of the two independent feed units operated by an electronic control circuit receiving signals generated by the optical edge detector.  The apparatus also includes means to maintain the image receiving section of the photosensitive medium in a flat plane.  An image placement carriage carrying optical elements is supported on magnetic slider pads forming bearing elements which hold the carriage onto smooth tracks made of magnetic material, thus minimizing or eliminating vibrations from the motion of the carriage and improving the quality of the images formed on the photosensitive medium.

Abstract: A resuscitation and inhalation device which can be used alternatively in each of two modes. The flow of oxygen or gas is controlled by a control valve (21), itself controlled by a movable member acted upon by the pressure of oxygen or gas in a chamber (27) after having flowed passed the control valve (21). On meeting a preset maximum pressure, the valve member (30) moves to close the control valve (21). The movable valve member (30) is acted upon by a magnetic field which is adjustable and the magnetic field strength sets the pressure at which the valve member (30) moves. Oxygen or gas is admitted to the control valve (21) by two alternative inlet valves (12,14), one for resuscitation with only oxygen or gas flowing through the mask, and one for inhalation, with a mixture of oxygen or gas and air or a second gas being fed through the mask. <IMAGE>   <IMAGE>

Abstract: CHAIR                ABSTRACT OF THE DISCLOSURE A chair comprises an elongated one-piece seat-and-back support bent so as to form a lower substantially U-shaped seat support and an upper substantially upright back support.  The seat support includes lower and upper leg portions and a bight portion-intermediate the same.  The bight portion is resilient thereby enabling the upper leg portion to deflect downwardly relative to the lower leg portion, and the back support to move downwardly and rearwardly, in response to a downward force exerted on the upper leg portion.  In addition, the chair comprises a stabilizer means mounted between the upper and lower leg portions of the seat support for providing stability to the same during downward relative deflection of the upper leg portion.  The chair further comprises resilient stiffening means and a tension control means.  The stiffening means is mounted to and between the seat support upper and lower leg portions and functions to increase resistance to relative deflection of the upper leg portion.  The tension control means is movably mounted relative to the lower leg portion of the seat support for adjustable engagement with the stiffening means to adjust the same's resistance to relative deflection of the seat support upper leg portion.

Abstract: ABSTRACT OF THE DISCLOSURE      A method of checking the functioning of a driving wheel slip control system installed in a vehicle.  Driving wheels are placed on support rollers and rotatably supported thereby.  The driving wheels are driven by the engine.  False signals indicative of tentative rotational speeds of trailing wheels are supplied to an ECU which in turn outputs a control signal for controlling the engine.  Predetermined monitoring signals including at least the control signal outputted from the ECU are taken out from the driving wheel slip control system.  It is determined whether the predetermined monitoring signals show values falling within respective predetermined allowable ranges.  Further, a steering handle of the vehicle may be turned et the same time of rotation of the driving wheels, the steering angle of which is detected by a steering angle sensor.  Further, instead of using the false signals, the trailing wheels may be placed on second support rollors for rotatably supporting the trailing wheels thereby.  The second support rollers are capable of rotatively driving the trailing wheels.
Patent CA-2021703-A1 (CA)
IPC: F16C32/06
Filed: 1990-07-20
Abstract: This invention relates to an axial bearing system intended for a radially mounted shaft (1) and has two hydrostatic axial bearings (4, 5) capable of axial movement relative to a surrounding bearing housing (3).  The bearing system comprises a flange (6, 7) with a pressure surface (6a, 7a) rigidly attached to the shaft (1), at an essentially right angle.  An annular chamber bearing (8, 9) has a surface (8a, 9a) facing towards the pressure surface (6a, 7a). In this there is an annular groove (8b, 9b).  The surface (8a, 9a) forms together with the pressure surface (6a, 7a) inner and outer sealing gaps to either side of the annular groove.  This, together with the pressure surface (6a, 7a), forms an annular chamber (8b,  9b)  into which hydraulic fluid is introduced under pressure.  The annular chamber bearing (8, 9) together with the bearing housing (3) forms a hydraulically pressurized chamber (15, 16) which forces the annular chamber bearing (8, 9) against the pressure surface (6a, 7a).  The two annular chamber bearings (8, 9) are forced in mutually opposing directions in this case. At least one of the flanges (6, 7)  is capable of being disassembled from the shaft (1), and in that the pressure surfaces (6a, 7a) face towards one another, that is to say the forces arising from the hydrostatic bearings and acting on the shaft (1) are directed away from one another.
