Abstract: ABSTRACT     The invention is a catalyst composition useful in the dealkoxyhydroxymethylation of formaldehyde acetals prepared by a specific method. The catalyst is precipitated from the reaction mixture resulting from the dealkoxyhydroxymethyla-tion of a formaldehyde acetal with syngas in presence of a mixture of Co2(CO)8 and Ru3(CO)12 as catalyst.          The precipitated catalyst has better activity than a mixture of Co2(CO)8 and Ru3(CO)12.

Abstract: POLYMERS TREATED WITH ELECTRON-DONOR DOPANTS     ABSTRACT         Polymers with conjugated backbones, both polyacetylene and polyaromatic heterocyclic types, are doped with electron-donor agents to increase their electrical conductivity.  The electron-donor agents are either electride dopants made in the presence of lithium or dopants derived from alkalides made in the presence of lithium.  The dopants also contain a metal such as cesium and a trapping agent such as a crown ether.

Abstract: Abstract of the disclosure:             HOE 84/F 257 A process for the production of shaped articles from sili-cate material by extrusion and/or pelleting and subsequent annealing is described.  In this process, pulverulent layered silicic acids of the general formula HZSiyOZy+1, in which y is a number from 1.7 to 24, or salts thereof, in which all or some of the H is replaced by at least one cation from the group comprising Li+, Na+, K+, NH4+, Ca2+, Cu2+, Co2+, Ni2+ and Mg2+, are mixed with water or an organic solvent, the mixture is extruded and/or pelleted to give roll-shaped or tube-shaped pieces and these are then dried and annealed under conditions such that the starting material is chiefly converted into cristobalite and/or tridymite.  The same material can also be pressed in a molding tool under pressure.  Under these conditions, shaped articles which predominantly consist of cristobalite or tridymite and have a Shore hardness of at least 70 can be obtained.

Abstract: ABSTRACT OF THE DISCLOSURE The invention relates to an articulated streetcar train of two or more rail cars, in which the bogies are attached below each rail car centre in order to avoid having the bogies below the articulation point.  As a result all bogies may be of the same type of construction.  As second suspension between the car bodies and the bogies there is a rubber or pneumatic shock absorber, which is desired in such a way that it exerts horizontal recuperating forces in order to deflect the car bodies laterally in such a way that they follow the envelope curve when travelling around a curve.  This invention permits all the car bodies to be designed as identical modules; the bogies may be carrying and/or powered bogies, and the need for guidance means for the car bodies is eliminated.

Abstract: A B S T A C T            A swimming pool cleaner which includes a head 2 having an inlet 3 and an outlet 4 and a transversley contractable and expansible tubular member 15 between the inlet and the outlet.  A chamber 17 is defined within the head around the tubular member and the outlet from the head is extended by an extension pipe 13.  A suction communication is provided between the chamber and the outlet end of the extension pipe.

Abstract: ABSTRACT OF THE DISCLOSURE          The surface or a portion thereof of an article made of synthetic plastic material is rendered viscoelastic and/or plastically deformable, by a die member having a large number (usually at least several thousand) of fibrous projections applied to the surface such that the fibrous projections become embedded in the synthetic material and the material adheres to the projections.  The die member is applied for a short period during which the viscous material cools and increases its viscosity, whereupon the die is withdrawn from the surface.  A number of fibres are drawn outwardly before the die member detaches itself from the synthetic material; thereafter the fibres are cooled to a solid nonviscoelastic and/or nonplastically deformable consistency.  A coating and/or adhesive material when applied will embed the fibres to thereby create a strong bond.

Abstract: ABSTRACT OF THE DISCLOSURE    The present invention relates to a method for producing spinning nozzle plates having funnel-shaped preliminary channels in flow communication with nozzle capillaries.  Two embodiments of the method are provided which use photolithograhic and electrodeposition techniques.  Common to both embodiments of the method is the use of a metal plate provided with funnel-shaped preliminary channels as a self-aligning irradiation mask for irradiating a photoresist layer provided on the metal plate.  Nozzle capillaries subsequently defined either in an electrodeposited layer according to a first embodiment of the invention or in electrodeposited tubular projections according to a second embodiment of the invention, have an offset-free, continuous transition between themselves and the preliminary channels.  Photolithographic and electrodeposition techniques may also be used to define the funnel-shaped preliminary channels in the metal plates.

Abstract: METHOD AND APPARATUS FOR DRYING FILAMENTARY MATERIAL          Abstract of the Disclosure In a method and apparatus for drying filamentary material, a duct is provided for enclosing a portion of a passline. The duct comprises two parts relatively disposed laterally of the passline.  These parts are relatively movable away from one another laterally of the passline to provide a duct open position and towards one another to provide a duct closed position.  First and second guide wheels are provided for guiding the filamentary material along the passline through the duct.  The guide wheels are relatively movable along the passline between the duct parts in the duct open position between a first pair of relatively close positions and a second pair of positions at opposite ends of the duct.  With the duct in the duct open position and the guide wheels in the first pair of positions, filamentary material is fed over the guide wheels.  The guide wheels are moved relatively along the passline from the first pair of positions to the second pair of positions to draw the filamentary material along the passline between the duct parts.  The duct parts are moved into the duct closed position to enclose the filamentary material extending between the guide wheels.  A drying gas is passed into the duct while advancing the filamentary material along the passline and guiding it through the duct.  The method and apparatus are useful for drying solvent-based colourants on polymer-insulated wire.

Abstract: A method for the manufacture of a number of self-adhesive labels 4, which are supported on a backing of dispensing material, consists in cutting out a laminate material 8, which comprises a fabric, which on its back is coated with a pressure-sensitive adhesive, and which has a backing of a dispensing material. Cutting out is performed in such a way that all layers of the laminated material are cut out with the exception of the backing layer, and thus in order to cut out a number of spaced label blanks 22 on the backing. Thereafter an adhesive is applied (at 14) either over the entire upper side of the fabric or over an area inside each label blank 22. Next, waste parts 16 of the fabric are removed from the label blanks from the rear, and either a folded sheet and cover 26 are applied, or a multilayer label or a label containing an object that is designed to cover the area of each label blank 22, which has been coated with adhesive. The series of self-adhesive labels 4 thus produced is wound onto a reel 2, providing an appropriate supply of labels for easy and effective application to containers that are to be labelled. <IMAGE>

Abstract: In a urination arrangement comprising a liquid container 5 with neck, consisting of a soft and flexible material and with a self-closing inlet valve 9, fashioned as a flat hose piece, between the inner opening of the neck and the interior of the container, the liquid container is fashioned in its shoulder regions with a hole 12, 13 for coupling with a stiffening and hanging element 1, which element comprises a hook 4 for securing or hanging the liquid container and hooks 2, 3 for coupling together with the holes 12, 13 of the container, thereby mutually stiffening the holes of the container, so that their mutual distance is maintained, even under loading of a full container. This accomplishes a tightening in the neck region, which contributes to maintaining the inlet valve closed. An at least semirigid, flat insert 15, which can be placed in the neck, will keep the neck distended upon distension, so that the valve is forced to open. In any case, the insert has a projecting part 17 at one flat side, which protrudes into the container, and which contributes to a distension of the valve and to holding the neck in the slanted position when the container is placed on a support. <IMAGE>
