Abstract: PCT No. PCT/GB89/00712 Sec. 371 Date Jan. 11, 1991 Sec. 102(e) Date Jan. 11, 1991 PCT Filed Jun. 26, 1989 PCT Pub. No. WO89/12533 PCT Pub. Date Dec. 28, 1989.Flexible tubular film is helically cut into a flat strip by feeding the tubular film in flattened form from a supply source to a film feeding means advancing the flat film tube at a predetermined velocity to a tube expansion zone in which the flat tube is expanded into a generally cylindrical tube and passed axially over a hollow mandrel slightly less in external diameter than the diameter of the expanded tube to be cut helically while on the mandrel into a flat strop that is removed at an angle to the mandrel axis. The tube is expanded in the zone by inflation with air fed through the mandrel in a direction countercurrent to the direction of tube movement and under a pressure sufficient to render the expanded tube stiff as it slides over the mandrel and resistant to deformation while being helically cut. The advance and expansion of the flat tube in the expansion zone is positively controlled by moving surfaces contacting the film, which surfaces define a diverging expansion zone and are driven at a velocity substantially at least as great as the predetermined velocity of advance of the flat film tube to the expansion zone.

Abstract: In a magneto-optical recording apparatus, light spots are successively formed on a magneto-optical disc (2) at a timing of a predetermined reference clock signal (SCK), and record data are magnetically recorded onto the disc (2) by applying a predetermined modulation magnetic field (HM) of which the polarity is inverted depending on the record data in synchronism with the reference clock signal (SCK). At least one of the timing of irradiating a light beam (LA1) forming the light spots, the light volume of the beam or the irradiation time is controlled depending upon the temperature of the disc (2) and/or the scanning position of the light spot, in order to form a pit (P) at a correct position relative to the timing of the reference clock signal (SCK). <IMAGE>

Abstract: This invention relates to a pneumatic control device having an operating mode selecting means for operating in either the manual or automatic modes. Pneumatic pressure is regulated in the manual mode by a hand operated leakport, and in the automatic mode by a voice coil or other pressure regulating device. The pneumatic input supply, manual pressure regulating means and voice coil all communicate at a common surface. The mode selecting means slides across this common surface to connect together the pneumatic input supply with one of the selected pressure regulating means.

Abstract: The present invention solves the problem of delignifying technical cellulose pulp in a selective manner which will result in very low residual contents of lignin in the pulp and a correspondingly high quantity of lignin dissolved in spent liquors, which are recovered in the chemical recovery system of the pulp mill. The invention constitutes a method and comprises activating liquid-containing lignocellulosic material in the presence of nitrate with a gas that contains nitrogen dioxide, followed by the alkaline delignification of the lignocellulosic material, and measuring the acidity of the liquid accompanying the material on at least one occasion during the activation. The method is characterized in that the acidity of the liquid is measured subsequent to bringing the time derivative of the nitrate concentration of the liquid, expressed as millimols per litre of liquid per minute, to a level beneath +0.2, and by using the measured acidity value to establish the optimum amount of mineral acid for continuation and termination of the activation, and by charging the whole of this quantity or a part of this quantity of mineral acid to the lignocellulosic material.

Abstract: A canned motor equipped with a stator chamber, a load side bearing bracket and a counter load side bearing bracket disposed on the load side and counter load side of the stator chamber respectively is disclosed. The stator chamber is formed by integrally welding a stator core, an outside can, an inside can, a load side end plate and a counter load side end plate. The load side bearing bracket and the counter load side bearing bracket each includes a bearing boss supporting a radial bearing and a shaft seal thereon. The improvement consists of the end plate and the bearing bracket on the load side being integrally formed to provide a single shell structure and the inside can being welded to the bearing boss of the load side bearing bracket. By this arrangement, the number of components required for the motor are reduced, an axial length of the motor is shortened and heat radiation from the end surface of the stator chamber on the load side is enhanced.

Abstract: A method and apparatus for operating on the human eye detects changes in load, more specifically, mechanical impedance, of the transducer (300) and controls aspiration based on the load changes. A change from a lower load to a higher load indications that harder tissue is being encountered and accordingly causes aspiration amount to increase. Conversely, a change from a higher load to a lower load indicates that aspiration amount should be quickly decreased since the tissue which is being encountered is softer. One way to detect the impedance is by a sensor (1008), i.e., a piezoelectric element coupled to the operating needle detecting the movement thereof. <IMAGE>

Abstract: A friction clutch (20) coupling an engine (10) and a gear transmission (30) of a vehicle is controlled by a microprocessor based circuit using logic which defines operating modes according to engine (10) and clutch (20) conditions. During the time of clutch closure, when the vehicle is starting from rest in a startup or launch mode, the throttle or other engine control signal is restrained from quickly responding to the accelerator pedal (11). This avoids engine overspeeding which results from generating high torque before sufficient clutch capacity has been achieved. The control signal is developed as a function of the pedal (11) position under control of throttle logic which, in turn, is dependent on clutch operating modes defined by the clutch logic. The clutch operating modes are four modes for automatic clutch operation comprising touch point (81) approach mode which prohibits a throttle signal during initial clutch movement, creep mode or startup mode after touch point 81 occurs, and lockup mode for completing clutch closing when low clutch slip is attained. A non-automatic mode is entered before the accelerator pedal (11) is depressed or when engine (10) stall conditions are detected. <IMAGE>   <IMAGE>
