Patent ES-436774-A1 (ES)
Title: Method of manufacturing an overwrapped pressure vessel
IPC: B29C53/60
Filed: 1975-04-19
Abstract: A pressure vessel of the type wherein a metallic liner in the shape of a cylindrical portion with a dome-shaped portion at each end thereof is overwrapped by a plurality of layers of resin coated, single fiberglass filaments. A four-step wrapping technique reinforces the vessel with overwrap material at the most likely areas for vessel failure. Overwrapping of the vessel is followed by a sizing pressurization cycle which induces a compressive prestress into the liner and thereby permits the liner to deform elastically through an increased strain range.
Patent ES-437688-A1 (ES)
Title: Torsional vibration dampers
IPC: F16F15/12
Filed: 1975-05-14
Abstract: A torsional vibration damper for attachment to a torsionally vibrating element, such as the crankshaft of an internal combustion engine. The fatigue life of the damper elastomer is improved through internal reinforcement with a fabric to inhibit spreading of fatigue cracks. The dynamic spring rate, in compression, is increased through the use of fabric inserts. The temperature of the elastic member may also be lowered by the use of thermally conductive fabric. Such a material assists in conducting heat from the center of the elastic member to the sides of the damper where it may be more readily dissiptated.

Title: Solar energy collection system
IPC: F24S10/70
Filed: 1976-07-07
Abstract: A system for the collection and utilization of solar energy. A manifold is mounted on the roof of a building with a major portion of the manifold being contained within the building. A plurality of double-walled, glass solar energy collector tubes are inserted into that part of the manifold which extends above the roof of the building. A gas, such as air, completely fills the manifold and collector tubes. The gas is circulated from the manifold to the ends of the collector tubes from whence it returns, having been heated during the movement. A heat exchanger mounted in the manifold has a working fluid, such as water, passing through it. The heated gas impinges on the heat exchanger, giving up much of its energy to the fluid passing through the heat exchanger. The working fluid is then used for space heating or cooling functions within the building.
Patent ES-450960-A1 (ES)
Title: Timing recovery circuit for digital data
IPC: H03L7/10
Filed: 1976-08-25
Abstract: A timing recovery circuit receives a timing component signal and generates a signal having a frequency varying in response to a control signal. In response to a difference between the phase of the variable frequency signal and the phase of the timing component signal, the circuit produces a control component. In response to cycle slips between the variable frequency signal and the timing component signal, the circuit produces a series of pulses having a polarity related to the sense of the cycle slips and having a pulse rate directly related to the rate of the cycle slips except when amplitude of the timing component signals falls below a predetermined value whereupon no pulses are produced. The control component and the series of pulses are combined into the control signal that adjusts the frequency of the generated signal into synchronization with the timing component signal.

Patent ES-458022-A1 (ES)
Title: Film with pleat for packing and apparatus for manufacturing the same
IPC: B29C53/04
Filed: 1977-04-05
Abstract: Plastic film has in its main plane at least one fold which is stretched under tension across the main direction. The web is narrow and therefore fits into narrow folding machines. The film can be thicker than when required to be shaped by stretching alone and it is not stressed dangerously near to its limit. Film for use in automatic packing machines, has parallel fold in its main plane and is produced as continuous web. These folds are opened out by tension across the width in the machines, so as to wrap the articles concerned. When stretchable film is used, the folds are thus pulled out first before the film is then stretched.

Patent ES-472464-A1 (ES)
Title: Cutting tool
IPC: B26B19/20
Filed: 1978-08-09
Abstract: A shear is disclosed in a preferred form which is particularly suited for cutting and trimming hair and which includes means for varying the length of stroke of the cutting blade or blades which reciprocate generally parallel to the longitudinal axis of the handle, so that the unit can be manipulated in a manner similar to a comb or brush. The blade drive includes a transmission comprising a pair of eccentrics which are selectively phaseable to provide full range of stroke by addition and subtraction of their eccentric throws. The eccentrics are retained in their selected phase relationship by spring and frictional means which provide an overload release permitting the eccentrics to rephase to zero stroke when the imposed load overcomes the phase-retaining means. Control of the unit is effected by a rotatable and depressable button which controls the drive motor, adjusts the blade stroke by phasing of the eccentrics, and lowers the cutting blade or blades from a retracted position into a cutting position.
