Title: Steerable truck for a railway vehicle
IPC: B61F3/04
Filed: 1980-04-10
Abstract: A forced steering mechanism is connected to a truck to steer an axle and associated wheels. Coupling means are provided for loosely connecting the car body of a vehicle to the truck and the forced steering mechanism.

Title: Gripping device for a ring-spinning machine or a ring-twisting machine.
IPC: D01H9/00
Filed: 1981-11-10
Abstract: The device allows to grip the empty or yarn-covered bushes by means of pegs (13) placed on a bracket (11) arranged along the twisting or spinning machine, the pegs being intended to be threaded in the bushes (18) The bushes (18) are retained by the pegs (13) by compression of one into the other and the pressure effect is obtained in general with compressed air.

This arrangement has the advantage that if the bushes (18) are not properly arranged, the impact of the portion forward of the peg with the upper edge of the bush is avoided, and consequently the damage which would result therefrom, for example the destruction of the brackets or loss of compressed air.
Patent ES-8302847-A1 (ES)
Title: Hydraulic anchoring device for a haulage and/or winning plant
IPC: E21F13/10
Filed: 1982-02-03
Abstract: The invention relates to a hydraulic block anchoring for an underground haulage and/or winning plant, in which the hydraulic anchoring cylinders (19) are connected in an inclined position in an articulated manner between prop abutments (12) and the haulage and/or winning plant (10). In order to create a light anchoring device which is comparatively less complicated in construction but can be used in as versatile a manner as possible, prop abutments (12) are used in which only a single hydraulic supporting prop (14) is supported on a floor skid (13) in a foot joint, a connecting joint (22) arranged laterally next to the foot joint at the floor skid (13) and intended for the anchoring cylinder being offset in the shifting direction relative to the centre of the foot joint in such a way that, when the anchoring cylinder is extended halfway, its lengthened cylinder axis passes approximately through the centre of the foot joint or the perpendicular to the foot-joint centre. In this way, the moment produced at the prop abutment (12) by the anchoring cylinder (19) is kept low and unfavourable torsion or deformation forces are prevented from being passed into the prop abutment. In addition, the prop abutment is of symmetrical design and is provided here with joint trestles (18), arranged on either side of the prop, for the connection of at least one anchoring cylinder (19) and if need be a chain (31) via which the prop abutment can be shifted by means of the anchoring cylinder.

Title: Method of coating optical fibers with metallic materials.
IPC: C03C25/10
Filed: 1984-03-23
Abstract: A metallic material coating is applied to the external surface of a freshly drawn optical fiber while such surface is still pristine by passing the optical fiber through a body of liquid metal-organic material which forms a layer on the fiber, and by subsequently removing all non-metallic components from the layer of metal-organic material by volatilizing the same. The optical fiber with the layer metal-organic material is passed through a baking oven in which at least the layer is heated to a baking temperature at which organic materials present in the metal-organic material are volatilized and the remainder is baked to the fiber. Then, at least the layer is fired in a firing chamber at a higher temperature at which the metal-organic material is decomposed into its volatile non-metallic and non-volatile metallic components, the latter remaining in the layer and the former becoming volatile and leaving the layer. Preferably, at least one layer of synthetic plastic material is applied over the thus obtained metallic layer. When the firing is done in an inert or reducing atomsphere, the metallic material is in its elemental form, while it is in its metal-oxide form when the firing operation is accomplished in an oxidizing atmosphere. Various printing inks and/or resinates may be used as the starting metal-organic materials in the process according to the invention.

Preferably, the steel is refined in a bottom blowing or bottom rinsing converter and after standardizing the Si - content and/or Mn - content, oxygen activity a[o] is measured and standardized to 60-150 ppm by adding a corresponding amount of an additional deoxidant, particularly aluminum.
