Abstract: PHN.10.466                 6                   5.1.1983 ABSTRACT:          "Method of and device for drawing an optical fibre from a solid preform consisting substantially of SiO2 and doped SiO2" .           Optical fibres are drawn from a solid preform which consists substantially of SiO2 and doped SiO2.          After leaving the conical zone the fibre is guided through a space having a laminar gas flow to restrict the temperature drop across the cross-section of the fibre and in the direction of drawing between 1200 and 1800° C so that no extra stresses are incorporated upon cooling. A device for carrying out said method comprises a quartz pipe through which the fibre is guided after leaving the conical zone and in which a laminar gas flow is maintained.

Abstract: Abstract of the Disclosure A wheelchair for handicapped or elderly persons which can be transferred into a front seat position in a normal passenger car without requiring substantial modification of the car is described.  The wheelchair has a generally rectangular frame with a set of retractable wheels.  A rear corner upright of the wheelchair frame is adapted to engage with a wheelchair hoisting transfer mechanism mounted in the car.  When the wheelchair is thus engaged and hoisted off the ground, the wheels are retracted to permit the wheelchair to be rotated about the corner upright.  The hoisted wheelchair is also moved laterally so that it is brought into a front facing position in the vehicle.

Abstract: ABSTRACT OF THE DISCLOSURE     In a container for accommodating hot liquid fills, an end closure capable of inward deflection in response to a decrease in internal pressure created by thermal contraction as the liquid fill cools.  The closure is formed of conventional metal stock and includes, as formed, a central portion domed to define either a concave configuration or a convex configuration as viewed from the exterior of the container.  The domed portion, as a step or steps prior to filling, is predeflected, either once or twice depending upon its initial configuration, to arrive at an outwardly domed configuration preparatory to inward deflection in response to the cooling of the product and for the accommodation of an internally generated vacuum.

Abstract: ABSTRACT OF THE DISCLOSURE:     A sheet splicer comprises two sheet roll support means, a table disposed above the sheet rolls held in place on the sheet roll support means and adapted to reciprocate above the table, and sheet guiding means disposed above the belt and adapted to reciprocate between the front and rear ends of the belt.  While the sheet from the first sheet roll is being pulled out over the sheet guiding means positioned beforehand at one end of the belt, the leading end of the sheet from the second sheet roll is covered with an adhesive agent and held in place at a prescribed position on the belt at the other end thereof.  As the sheet from the first sheet roll is completely drawn out of the sheet roll, the trailing end of this sheet is retained at that position and the sheet guiding means is moved to the other end of the belt.  Consequently, the leading end of the sheet from the second sheet roll is allowed to be joined to the trailing end of the sheet.  The splicer, accordingly, permits continuous supply of the sheet to a machine used for processing or treating the sheet.

The two wires pass over a secondary foil cover (4) which presents alternately solid and open areas to create pulsating pressure on stock between the wires, and then below a secondary trailing cover (10) whose leading edge doctors water on the top wire into an autoslice (9), and the top wire (14) is separated from the bottom wire (15) in the region of a sheet transfer box (11) to pass round a drive roll (13) and return to the lead-in roll.  The leading edge of the transverse bars (41) or blades of the secondary foil cover (4) doctor water off the bottom wire.  The secondary foil cover (4) and the secondary trailing cover (10) establish successively sharper downwardly forwardly and upwardly forwardly convex paths for the wires which promote dewatering.  A primary trailing cover (8) and a primary autoslice (7) can additionally be disposed above the top wire between the lead-in-foil cover (1) and the secondary foil cover (4).  The lead-in-foil cover and the secondary foil cover can form parts of a composite adjustably mounted unitary structure.

Abstract: LATENCY REMOVAL               ABSTRACT OF THE DISCLOSURE          The latency of mechanical pulp is removed in a quick and simple manner.  After refining of comminuted cellulosic material in a refiner to produce mechanical pulp, the pulp is fluidized at a consistency of about 5-30% to remove latent properties.  For instance, the pulp is diluted (if necessary) to a consistency of between about 5-30% (preferably 8-15%), and the pulp is then merely pumped to a further treatment stage.  Pumping is effected utilizing a centrifugal pump which fluidizes the pulp, the fluidization imparting sufficient energy to the pulp to remove the latent properties.  The pulp may be pumped to a storage stage prior to passage to a screening stage and can be pumped in a direct (non-return) path from the pump to the screening stage.  If desired or necessary, a portion of the pumped pulp can be recirculated and pumped again to ensure that sufficient energy is imparted thereto to effect latency removal.

Abstract: ABSTRACT    The invention relates to a method of manufacturing a  hydrogen-storing alloy based on the Laves phases AB2, where A is titanium and/or zirconium, and B is one or more elements from the remainder of the transition metal series, wherewith the ratio of the atomic radii of A and B, rA/rB, is between 1.05 and 1.68.  This is run by melting in vacuum or under a protective gas.    In order to achieve maximal hydrogen storing capacity, it is provided according to the invention: that the melting is carried out in a heating apparatus with a vessel lined with calcium oxide:  further, that in a first step a partial alloy is produced comprising the selected elements with the exception of titanium, zirconium, and cerium; that in a second step the partial alloy is deoxidized with titanium and/or zirconium added in an amount of ca. 0.1-0.2 wt.% (of the weight of the entire melt); that in a third step, following a holding time (at temperature) of at least 10 min, the remainder of the prescribed amount of the titanium and/or zirconium is added to the melt; and that the melt is thereafter abruptly cooled.
