Abstract: Abstract of the Disclosure A water-absorptive contact lens made of a copolymer comprising units of an ester of acrylic or methacrylic acid and at least one saccharide selected from D-galactose, D-glucose and D-mannose and units of at least one member selected from a hydrophilic monomer and a hydrophobic monomer, which has excellent oxygen permeability and affinity for the eye and can be worn continuously for a long period of time.  The contact lens is prepared by polymerizing a monomer mixture containing an ester of acrylic or methacrylic acid with a ketalized saccharide and a hydrophilic monomer and/or a hydrophobic monomer, and after forming the resulting copolymer into a contact lens, if necessary, treating the copolymer having a shape of contact lens with an acid to convert the ketal groups into hydroxyl groups.

Abstract: A B S T R A C T         The invention relates to an annular or closed loop rotatable frame or "flyer" (1), such as is used in a stranding machine or the type, in which two or more wires, fibres or strands are stranded to a cable, e.g. intended for tele-communication, the flyer being arranged to rotate around one or more bobbins (10, 11).         The frame (1) is journalled in two diametrically opposite points (8, 22) and is prestressed at these two journal points in a direction perpendicular to the centrifugal force produced by the rotation.         In this way a bending moment in the opposite direction is produced making it possible to increase the speed of rotation of the flyer.

Abstract: ABSTRACT OF THE DISCLOSURE      Bituminous sand such as oil sand or tar sand is mixed with a halogenated organic solvent which has a density greater than that of water at the same temperature.  The slurry is continuously trans-ferred to a conveyor system which is at least partially submerged in water, with the slurry being fed onto the portion of the conveyor which is submerged.  As the sands move through the water on the conveyor, the organic solvent containing the bituminous material separates from the sand and forms a separate phase beneath the water.  The sands ultimately move upwardly on the conveyor through the surface of the water.  The organic phase is removed from beneath the water surface and the halogenated solvent is flashed therefrom in a flash evaporator chamber.  Solvent vapors are withdrawn from the evaporator chamber by a compressor, and the compressed vapors are introduced into a condenser chamber.  A heat exchange medium is continuously circulated between the condenser and evaporator chambers, with heat being transferred from the heat exchange medium in the evaporator and back to the heat exchange medium in the condenser.  Bituminous organic material is withdrawn from the evaporator chamber and condensed solvent is recovered from the condenser.  Preferably, the heat exchange means comprises a plurality of heat pipes, with mutually respective end portions of the heat pipes extending into the condenser chamber and the other end portions extending into the evaporator chamber.

Abstract: F. 2033 BOTTLE-CAP AND POURING-FITMENT ASSEMBLY     ABSTRACT OF THE DISCLOSURE     The invention contemplates a bottle cap and a pouring fitment which are assembled to each other before being attached to a bottle.  The pouring fit-ment has an upper tubular part having a pouring-lip formation at its upper end and a radially outward seating flange at its lower end, the latter having provision for engagement over and retention by the upper end of the bottle neck.  Integral interior formations of the cap include an inner annular flange which has telescoping frictional engagement with the bore of the upper tubular part of the pouring fitment, and a stop-abutment formation within the cap compresses the seating flange to the end of the bottle neck when the cap is in tight threaded engagement with the bottle neck.  No part of the fitment extends within the bottle neck, but a pattern of radial struts within the base end of the tubular part of the fitment provides enhanced stiffness to augment the frictional engagement and to provide protection against rodent access to bottle contents, should the cap fail to have been replaced through careless use.

Abstract: ABSTRACT OF THE INVENTION          A method and arrangement for optically coupling a fiber optic element to the end surface of an optical device utilizing  a noncontact type coupling member.  The fiber  optic  element  includes  an  end  face  for  optical coupling to the end surface of the optical device, and has an outer protective coating along a portion of its axial length adjacent the end face of the fiber optic element. The outer diameter of the protective coating at an axial location  spaced  from  the  end  face  of the  fiber  optic element  is  of  a  first  dimension.  The  noncontact  type coupling  member  includes  a  first  support  surface  for supporting the end face of an optical device in a first predetermined position,  and a second support surface for supporting a contact portion of the protective coating of the fiber optic element in a second predetermined position axially spaced from the first predetermined position. The protective coating of the fiber optic element has a shape such that the contact portion thereof defines a surface which has an outer diameter less than the first dimension. Also, a coating is provided on the end face of the fiber optic element so as to substantially cover the end of the core region thereof.  Such covering coating has a prede-termined  index  of  refraction  which  is  substantially greater than the index of refraction of the medium between the  end  face  of  the  fiber  optic  element  and  the  end surface of the optical device when the fiber optic element and optic device are supported in spaced axial relation-ship,

Abstract: FAULT-TOLERANT COMPUTER SYSTEM            ABSTRACT          A fault-tolerant computer system provides information transfers between the units of a computing module, including a processor unit and a memory unit and one or more peripheral control units, on a bus structure common to all the units.  Information-handling parts of the system, both in the bus structure and in each unit, can have a duplicate partner.  Error detectors check the operation of the bus structure and of each system unit to provide information transfers only on fault-free bus conductors and between fault-free units.  The computer system can operate in this manner essentially without interruption in the event of faults by using only fault-free conductors and functional units.           Arbitration circuits of unusual speed and simplicity provide units of the computing module with access to the common bus structure according to the priority of each unit.           The units of a module check incoming and outgoing signals for errors, signal other module units of a detected error, and disable the unit from sending potentially erroneous information onto the bus structure.

Abstract: Abstract of the Disclosure A warm air blowing heater includes combustion equipment for burning fuel, and an air duct provided at the position away from a portion directly above the com-bustion equipment for blowing air from the heater into the room.  The combustion equipment includes a burner chimney provided above a burner, and a reflecting plate is provided behind this burner chimney.  The radiation heat of the combustion equipment is radiated directly and is also reflected on the reflecting plate to heat the room.  The air duct does not disturb the rise of the combustion exhaust gas of the combustion equipment to form a smooth rising exhaust gas stream.  When the air is blown from the air duct toward the front of the heater, the high temperature air in the upper portion of the heater is sucked.  This high temperature air is mixed with the air blown from the air duct to allow the heater to blow warm air into the room.  The blower motor may suck the air in the room and supply it to the air duct.  When the blower motor, however, sucks the outdoor air and blows it from the air duct into the room, the air in the room can be simultaneously exchanged for good circulation.

The stretch film (14) is wound over the material web (24). The stretch film can be one with a smooth and a sticky side, and which is pulled out from a supply (4). Winding the stretch film can be interrupted when  he supply (4) is opposite one end surface of the article while the article rotation is continued a half turn, whereby the stretch film is laterally reversed in relation to the article. The film (14) can be initially wound with its smooth side in contact with the article (1) and later easily laterally reversed so that its smooth side is turned outwards to form the exterior of the article wrapping.
