Title: An optical fibre connector.
IPC: G02B6/36
Filed: 1982-08-17
Abstract: An optical fibre connector comprising a first member composed of a rigid material and formed in one surface thereof with an elongated groove for axially receiving respective end portions of a pair of optical fibres to be interconnected, a second member substantially identical with the first member and engageable therewith such that said grooves are in registration and can locate therebetween the end portions of said pair of fibres, with the end portion of each fibre being fixed relative to a respective one of the members, and a resilient element which, when said first and second members are interengaged, co-operates with said first and second members. The resilient element and said members are such that one end of the resilient element is anchored relative to the first member at a position between the free end of the end portion of one of the fibres and the point at which said one fibre projects from the first member, while the other end projects from the first member, while the other end of the resilient element is anchored relative to the second member at a position between the free end of the end portion of the other fibre and the point at which said other fibre projects from the second member. The resilient element is stressed when co-operating with said interengaged first and second members and being arranged so as thereby to impart to the first and second members a force having a first component in a direction urging said one surfaces together, and a second component in a direction parallel with the axes of the fibres so as to apply a sliding force to the members.

Title: Polyurethanes useful as engineering plastics.
IPC: C08G18/10
Filed: 1982-09-30
Abstract: Polyurethane resins are described having high impact strength and other structural strength properties, and significantly improved resistance to deformation by heat. The properties of these materials are such as to make them comparable to engineering thermoplastics such as nylon and like materials commonly used to fabricate structural components such as automotive parts, equipment housing, sporting goods, furniture, toys, household and like consumer goods. The resins are prepared from organic polyisocyanates, an isocyanate-reactive material (polyol, polyamine, etc.) having an average functionality of at least 1.9, a Tg less than 20 DEG C. and molecular weight of 500-20,000, and one or more low molecular weight extenders the major distinguishing feature being the markedly lower proportion by weight (2 to 25 percent) in which the isocyanate-reactive material is employed as compared with polyurethane resins conventionally prepared in the art. Depending upon the particular combination of reactants employed the polyurethanes of the invention can be thermoplastic or thermoset and can be prepared in both cellular and non-cellular form.

Abstract: Novel method for visually detecting the colour of a liquid in a series of containers which contain different concentrations of dye (colourant), in which detection takes place in the presence of one or more additional dyes which give rise to the observation of different colours or tones of colour in the containers which contain the various concentrations of the first dye.
Patent ES-8503087-A1 (ES)
Title: Electric actuator for railway braking system
IPC: F16D65/28
Filed: 1984-05-11
Abstract: The final output member (26) is moved to bring the brake block to engage the wheel. Effort applied by a spring (15) moves the housing (17) axially with a nut. As the housing moves a nut is rotated on a threaded part of a tube. Once the block engages the wheel the output member is temporarily arrested and the continued movement of the housing collapses a second spring. A shaft is forced into rotation by engagement of the threaded portion with the housing. This rotates a clutch-operating part and causes the clutch to halt rotation of the nut. As the motor (1) continues running, the nut is screwed to the left to compress the first spring (15). An increased output force is exerted on the housing and via the second spring (35) on the output member (26). In response to further spring compression the nut (48) is moved axially with the tube by a splined connection of a part to the hub of the nut (48). This moves a flange towards a stop.

Title: Image-producing process.
IPC: G03F7/023
Filed: 1985-03-06
Abstract: A positive photoresist is electrodeposited onto a substrate, exposed to actinic radiation in a predetermined pattern, and then exposed areas are removed by contact with a developer.

Title: Method and plant for the continuous heat treatment of a fine textile yarn.
IPC: D06B17/00
Filed: 1985-03-14
Abstract: Method and machine for the thermal or chemical treatment of a fine textile yarn on a conveyor belt. The yarn (8) is deposited in the form of turns (12) inclined rearwardly and formed by winding the yarn about a guiding stick (20) of which the lower side is bearing against the conveyor belt (2). A drive member (22) bears on the upper side of the stick and seizes successively each of the yarn turns formed on the base (24) of the stick at a point of which the position is adjustable. The turns are guided by the blade (25) of the stick inside a portion of the treatment housing (1). The transversal profile of the stick is particularly adapted to the progressive inclination of the turns and to the retraction of the yarn as a result of the heat treatment effect. The invention applies particularly to the treatment of fine yarns by steaming process.

Title: Therapeutical adhesive plaster and process for its manufacture.
IPC: A61K9/70
Filed: 1985-08-08
Abstract: In order that, in a plaster comprising a composite film having a recess for holding the medicament and having a layer of adhesive surrounding the recess and a composite covering film glued to the recess and covering it, the galenical may be optimized regardless of the properties of a matrix containing the medicament in the recess, it is proposed to close the recess by means of a membrane which is firmly connected to the composite film and is permeable to the active ingredient of the medicament, and to join the composite covering film hermetically to the composite film along a ring extending between the central membrane and the surrounding layer of adhesive. To provide a process for the production of such a plaster in which two separately produced, outer parts of the plaster are joined together in a separable manner by means of an inner layer of adhesive, which process should be capable of rational mass production of the plaster, it is proposed to produce the layer of adhesive as a component of an inner, third part of the plaster, which is produced separately from the two outer parts of the plaster and is subsequently firmly connected to these outer parts.
