Title: Improvements in kiln floor systems with rollers.
IPC: F27B/
Filed: 1979-02-06
Abstract: A kiln floor on rollers includes a chamber or zone to heat the pieces of work to the desired temperature and maintain this for the appropriate period of time for the particular thermal process cycle being undertaken. The oven interior includes a transport and support floor for the pieces of work that is composed of one or more cylindrical rollers. The rollers have mounting sections to position the rollers in the oven chamber. Each mounting section is loosely supported by a supporting sleeve with an opening of greater cross-section diameter than the diameter of the mounting section it supports. A propelling system makes the sleeve turn so as to propel the rollers. The oversized roller retention sleeve allows for the thermal dilation of the roller in all directions and can automatically compensate unevenness in the roundness of the rollers that may occur particularly at high temperatures.

Patent ES-8102312-A1 (ES)
Title: Method and apparatus for laying a pipeline on the sea-bottom.
IPC: F16L1/20
Filed: 1979-11-26
Abstract: Apparatus and method for laying a pipeline on the bottom of an ocean wherein a wheel-like, buoyant body is adapted to carry a single, continuous length of pipe in the form of horizontal convolutions from a first site at which the pipe is wrapped on the body to a second site where the convolutions are moved into vertical positions and the pipe is unwrapped from the body and allowed to gravitate toward and to be laid on the bottom of the ocean. The pipe is wrapped on the body when the latter is horizontally disposed and floating on the water near a dock, and the wrapping can be accomplished whether the elastic bending limit of the pipe is exceeded or not. The body with the convolutions of pipe are towed to the second site while the body and the pipe remains horizontally disposed. Then a tank forming part of the body receives sea water to unbalance the body and cause it to be moved into a vertical position. In this position, the body is simultaneously towed forwardly and rotated about a horizontal axis below the upper level of the water to allow the pipe to be vertically unwrapped from the body and to gravitate therefrom. The body normally has a curvature less than the curvature at which the pipe exceeds its elastic bending limit however the body could have a greater curvature for some specific uses. A second, smaller tank having a power actuated mechanism therein is coupled by gear means to the body near its outer periphery to rotate the latter upon actuation of the mechanism during a pipe laying operation. The mechanism can also be used to rotate the tank when the body is in a horizontal position near a dock to allow the pipe to be continuously wrapped onto the body after being formed from pipe segments connected together in end-to-end relationship.

Title: Color TV display system
IPC: H01J29/56
Filed: 1981-05-13
Abstract: A self-converging deflection yoke having toroidally-wound vertical deflection coils incorporates a pair of magnetically permeable field formers mounted on either side of the yoke. The field formers shunt a portion of the external field flux to the vicinity of the electron gun assembly where they form a pincushion-shaped field which aids in vertical coma correction. In one embodiment, a yoke comprising planar-wound vertical coils incorporates both coma-correcting rear field formers and a pair of front crossarm assemblies for providing side-pincushion correction. The resultant yoke provides covergence of electron beams free of coma and side-pincushion distortion with reduced sensitivity to transverse motion. In another embodiment, similar results are obtained without the front crossarms by vertical deflection coil having a nonradial winding configuration.

Title: Method of producing fibre-reinforced composition.
IPC: C08J3/18
Filed: 1983-07-28
Abstract: A process of producing a fibre-reinforced composition comprising drawing a plurality of continuous filaments through a melt comprising a mixture of a thermoplastic polymer and a plasticiser for the polymer in the weight ratio between 1:4 and 99:1 of polymer to plasticiser, preferably in the weight ratio 1:1 to 19:1, the plasticiser being thermally stable at least up to the temperature of the melt and having volatility characteristics such that the plasticiser is not substantially volatilised from the composition below the melt temperature of the thermoplastic polymer but has a sufficiently low volatility at the temperature of the melt to plasticise the polymer in the melt and give a melt of reduced viscosity compared with the melt viscosity of the polymer alone. The process enables improved fibre wetting and/or easier processing to be achieved in comparison with a process in which no plasticiser is used. Higher molecular weight polymer may also be used than when plasticiser is absent.
