Patent ES-448007-A1 (ES)
Title: Electrical apparatus comprising parts of rigid foam
IPC: H01B3/56
Filed: 1976-05-17
Abstract: In spite of starting raw materials which, in terms of production, do not appear to be favourable for insulating purposes, mechanically load-bearing, low-temperature withstanding rigid-foam insulating parts of electrical equipment must not only be of a material-saving and consequently weight-saving design but also in particular must be able to bear high mechanical loads and have an adequate high-voltage resistance as well as extensive thermal insensitivity in the range of the operating temperatures. In order to achieve this, the foam framework of the rigid-foam insulating parts consists of expandable polymers, in the foam cells of which there is at least one blowing agent, serving as a dielectric, which has at most a dielectric strength similar to that of air. It is particularly advantageous in this case if the rigid-foam insulating parts have an integral foam structure, the foam framework consists of polyurethane or epoxy resin and the blowing agent contains low-boiling Halocarbons or low-boiling noble gases but also sulphur hexafluoride, oxygen or hydrogen as a blowing agent additive. Such rigid-foam insulating parts are distinguished by good flexural, compressive and tensile strength, also by a particularly dielectric strength, the long-term electrical behaviour of the parts being affected little by the blowing agent being partially replaced by air.

Title: Impulse voltage distribution improving partial-turn electrostatic shields for disc windings
IPC: H01F27/34
Filed: 1977-09-26
Abstract: A disc wound winding formed of a plurality of spirally wound, disc coil sections and having series capacitance increasing electrostatic shields in less than all of said sections, incorporates partial-turn electrostatic shields in disc coil sections adjacent that portion of said winding not having electrostatic shields. With this arrangement, a substantial reduction in the change in series capacitance between the shielded and unshielded portions of a disc wound winding is effected which minimizes unsatisfactory impulse voltage build-up at the beginning of the unshielded portion of said winding.

Title: Apparatus for the subaqueous entrenching of pipes.
IPC: E02F5/02
Filed: 1979-03-22
Abstract: The invention relates to an apparatus for the entrenching of pipes in underwater beds, of the type in which a framework, provided with excavating means, is positioned across the pipe to be entrenched and dragged along the pipe so as to excavate two parallel trenches adjacent to both sides of the pipe, the pipe being entrenched due to the collapsing (either spontaneous or caused by disgregating means) of the bed zone thus remaining under the pipe already laid onto the bed. The excavated material is removed by means of a pump and discharged again, at a predetermined distance from and rearwardly of the framework, on the entrenched pipe. The framework is provided with side supporting skid members, by which furthermore the entrenching height is adjustable.

Patent ES-8101669-A1 (ES)
Title: Sewing machine with a stitch setting device
IPC: D05B27/22
Filed: 1980-04-15
Abstract: A sewing machine includes a material engaging part such as a dog which is engageable with a material workpiece to selectively feed it in a forward and a reverse direction. In addition, the sewing machine includes the usual mechanism for raising and lowering the dog so as to complete an advancing or reverse movement of the material. The dog is driven preferably by a mechanism which includes an eccentric which may be adjusted so as to vary the length of horizontal feeding movement of the dog while the elevational changes of the dog remain constant by a separate feeding control mechanism. The magnitude of movement of the dog is controlled in accordance with a stitch length to be sewed by a stitch setting device which includes a movable contacting member which is connected to the eccentric mechanism and is movable between two end positions in order to adjust by a selected amount the movement of the eccentric in driving the dog by a selected amount. The device also includes first and second setting members arranged on respective sides of a contacting member which may, for example, be in the form of a fluid operated piston and a setting member positioning means is connected to the two setting members so as to move them simultaneously in respective opposite directions and position them on respective opposite sides of the contacting member or piston so as to control the end positions of movement of the piston during the operation of the sewing machine. The piston rides in a fluid cylinder and fluid pressure may be applied to respective sides thereof for shifting the position of the piston for the purposes of reversing the direction of feeding movement of the material being sewn.

Patent ES-8300811-A1 (ES)
Title: Process for the production of polyurethane polymer compositions.
IPC: C08K5/54
Filed: 1981-12-29
Abstract: The invention is concerned with the preparation of polyurethane compositions in which the deleterious effect of gaseous by-products formed in the reaction is minimized. This is achieved by the use of coupling reagents which incorporate a steric hindrance function. The latter does not interfere with the normal coupling reactions between the coupling agent and polymer matrix and filler material but it does prevent such reaction between the coupling agent and filler material as would cause release of low molecular weight compounds occluded by the filler. Since the release of low molecular weight compounds is avoided, the formation or evolution of gases which give rise to unwanted cellularity of the cured composition is at least minimized.
