Abstract: ABSTRACT OF THE DISCLOSURE              Methods and apparatus for performing accommodation training under clinical conditions are provided in accordance with the teachings of the present invention. An infrared optometer is employed to measure a patient's accommodation and outputs there-from are employed to generate tone information and viewable patient information indicative of the state of focus in a rapid manner. A patient is trained at an empirical rate determined by the viewable information until a predetermined proficiency in the voluntary control of accommodation is achieved. Thereafter, stimuli to accommodation, the accommodation convergence reflex and blur cue information are selectively introduced to generalize the voluntary control of accommodation achieved to a conventional environment so that the same may serve to reduce various visual acuity problems in a patient being trained.

Abstract: ABSTRACT OF THE DISCLOSURE A novel method is provided herein for making paper or paperboard with a higher dry strength than previously by adding to the fiber pulp suspension a smaller amount than previously of cationic, water-soluble starch and a synthetic retention agent.          In addition, a filler can be added to the fiber pulp suspension.          According to the invention, cationic, water-soluble starch is added to the fiber pulp suspension at only 0.02-1.5% (as calculated from the dry weight of the pulp) and the synthetic retention agent (which is selected from the group consisting of polyacrylamides, their derivatives and copolymers), is added at only 0.005-0.1%, (also as calculated from the dry weight of the pulp).  The addition can be made either to a fiber pulp suspension which is substantially free from filler, or part of the retention agent may be added to the fiber pulp suspension before the adding of the filler, or a pre-treated filler may be added to the fiber pulp at some other stage.

Abstract: ABSTRACT     An optical fibre ribbon structure suitable for use in an optical cable or other application where there is a risk that optical fibres will be subjected to a tensile force comprises a plurality of optical fibres and flexible reinforcing elements of resilient material arranged side by side and embedded in an elongate plastics body.  Each resilient reinforcing element is set in such a form that the ribbon structure follows a path of smoothly curved undulations whose axes of curvature lie parallel to one another and normal to the longitudinal axis of the ribbon structure.  When the undulating ribbon structure is subjected to a tensile force, the ribbon structure straightens in a lengthwise direction against the action of the resilient reinforcing elements thereby reducing the tensile force otherwise applied to the optical fibres.          When the tensile force is removed, the ribbon structure returns towards its original undulating form.

Abstract: ABSTRACT        An apparatus is disclosed which is operative to remove oxidizable particulates from the exhaust gas of an engine.  It has a particulate filter trap disposed in a stream of exhaust gases from the engine, and has electri-cally heated elements effective, when at least a portion of the stream of exhaust gases is displaced with a fluid medium for transfering heat between the elements and the collected particulates, to promote oxidation of the particulates collected in the filter trap.  The electri-cally heated elements are supplied with energy generated by an alternator driven by the engine; the elements are first heated to an incineration temperature for the particulates in the absence of gas flow, and heating of the elements is continued in the presence of a flow of an oxygen carrying heat transfer medium to promote complete oxidation of the particulates.

Abstract: ABSTRACT OF THE DISCLOSURE       The wall of the pipe section comprises a plurality of superimposed layers, which are formed from plastic and inorganic materials.  The layer of inorganic materials forms the central layer, whose wall portions are in each case connected by a connecting layer to a reinforcing layer. Whilst the central layer ensures the dimensional rigidity of the pipe section, the two reinforcing layers, which are made from a fibre-reinforced plastic, ensure the strength of the pipe.  This combination of different layers is an inexpensive solution, which only requires that amount of expensive plastic as is required for the strength of the pipe. Through applying a plastic protective layer to the outer circumference of the pipe and a protective layer to the inner circumference of the pipe, the durability of the pipe section is ensured.

Abstract: SUPERCHARGE PRESSURE CONTROL APPARATUS        OF A SUPERCHARGED ENGINE                ABSTRACT OF THE DISCLOSURE There is a supercharge pressure control apparatus of a supercharged engine.  A bypass is provided to bypass a supercharger turbine arranged between the intake and exhaust passages.  A waste gate valve is attached at one end of the bypass and is coupled to an actuator having a pressure chamber communicated with a connecting passage which is branched at a branch point into the first and second passages.  A first port is formed in the intake passage downstream near a suction inlet of a compressor and a second port is formed in the intake passage downstream of the first port.  In the stationary operating state, the connecting passage is communicated with the second passage by the change-over valve, so that a high pressure from the second port acts on the pressure chamber and the supercharge pressure is maintained at a set level.  In the acceleration operating state, the connecting passage is communicated with the first passage for a predetermined time, so that a low pressure from the first port acts on the presssure chamber.  When the pressure at the first port reaches the set level, the pressure at the second port exceeds the set level, so that the supercharge pressure over the set level is supplied into the engine.  After a preset time, the connecting passage is communicated with the second passage and the pressure is held at the set level.
