Patent ES-417256-A1 (ES)
Title: Concrete pipes
IPC: F16L9/08
Filed: 1973-07-26
Abstract: A pipe of concrete, cement mortar or other cementitious material is formed by an integrally cast cementitious mass which is reinforced with a glass fibre strand or roving forming a substantially helical winding extending around the pipe and incorporated in the cement matrix of the cementitious mass. Preferably there are two windings, one incorporated in the outer periphery of the mass and the other incorporated in the inner periphery of the mass. The pipe is preferably made by a centrifugal casting operation in which a centrifugal casting mould is rotated and the glass fibre strand or roving is fed from a feeding device within the mould and is caused to adhere to the internal peripheral face of the mould and then the feeding device is moved axially along the mould as the mould rotates so that the winding is formed from the roving around the internal peripheral face of the mould. The concrete or other cementitious material is introduced into the mould at the same time as the glass fibre roving or subsequently and the winding becomes incorporated in the cement matrix of the cementitious material as the mould continues to be rotated.

Patent ES-426121-A1 (ES)
Title: Stabilized plinth assembly for a hydrotherapy treatment system
IPC: A61G7/10
Filed: 1974-05-09
Abstract: The stability of a hoist-controlled hydrotherapy plinth is enhanced by a unique two-point suspension system having rigid end supports pivotally coupled to the plinth's head and foot ends on its longitudinal axis. A spreader bar, parallel spaced above the plinth, interconnects and holds the end supports in their upright positions wherein they automatically lock to the plinth. The rigidity of the four-sided structure formed by the plinth, end supports and spreader bar stabilizes the plinth against rotation around its axis, thereby effectively precluding the possibility of a patient rolling or falling off of the plinth. When a hydrotherapy treatment is completed and the plinth is elevated above the water level in the hydrotherapy tank, drainage of the water captivated on top of the plinth is facilitated by a rigid panel at the plinth's foot end. The construction of the plinth assembly also readily lends itself to encapsulation with a flexible plastic sleeve or sheath to eliminate patient cross-contamination that may otherwise occur.
Patent ES-434263-A1 (ES)
Title: Method of constructing a transportable prefabricated room element
IPC: E04B1/348
Filed: 1975-01-29
Abstract: In the embodiment of the invention described herein and shown in the accompanying drawings, a transportable prefabricated room element has a rigid frame or chassis which comprises a rigid base structure or floor panel structure and a vertical load-bearing structure permanently and rigidly fixed to the floor panel structure at an intermediate region in the length of the latter. This frame or chassis is preferably of inverted T formation in side elevation. At each side of the vertical structure, there is a prefabricated three-dimensional cell unit, each of which units consitutes a three-dimensional region of the room element and has a vertical wall and a roof or ceiling and/or a floor and is assembled to or with the frame or chassis in substantially-finished condition. At each end the floor panel structure freely supports at least one vertical load-bearing strut for carrying vertical loads imposed by a superimposed room element. These struts are at least partly enclosed in end walls of the extreme cell units. The extreme end walls of the cell units substantially coincide with or slightly overlap the ends of the floor panel structure. In a plural story building, the room elements are stacked on one another with their vertical load-bearing structures in register, and these registering vertical structures are post-tensioned together by post-tensioning means extending down through them:-possibly into a foundation of the building.
Patent ES-435705-A1 (ES)
Title: Method of making bottom seal thermoplastic bags
IPC: B31B23/00
Filed: 1975-03-17
Abstract: According to the present disclosure a method is provided wherein tubular thermoplastic material is intermittently fed between opposed transversely extending seal bars operating in timed relation with the intermittent feeding of the web to sequentially perform cutting and sealing of the web during its period of repose. To insure a clean straight transverse cut, which occurs momentarily before transverse sealing, the web is held under tension between longitudinally spaced draw and feed rolls. Immediately after the web is transversely severed, the seal bars are brought into pressure engagement transversely sealing the web along a margin which will define the bottom of the bag. While the sealed portion of the web is at the sealing station, cooling air is discharged along the sealed portion of the web to effect cooling. Before the web is fed an additional increment, it is momentarily fed rearwardly to avoid the possibility of adherence to the seal bars.

Patent ES-454622-A1 (ES)
Title: Method of starting a combustion system utilizing a catalyst
IPC: F23R3/40
Filed: 1976-12-28
Abstract: A method and system are provided for starting a combustion system utilizing a catalyst, and at the same time provide low emissions of unburned hydrocarbons and carbon monoxide.The method is particularly applicable to starting such combustion systems which are subject to intermittent operation, such as for example, gas turbines used to power automotive vehicles in which carbonaceous fuels are combusted to provide the motive fluid, or furnaces which are used intermittently. In the method, heat, such as produced by electrical means or by thermal combustion of a carbonaceous fuel, is employed to bring the catalyst to an operating temperature which will permit rapid oxidation of the carbonaceous fuel. When the catalyst has been heated to reach such operating temperatures, the start-up heating may be terminated and the normal operation of the combustion zone including the catalyst may proceed.

Title: Regulated dual DC power supply
IPC: H02M3/156
Filed: 1979-06-12
Abstract: A dual section power supply, one section for supplying high voltage dc power and the other section for supplying low voltage dc power, are each connected to a common ac source. The high voltage section employs a phase-controlled rectifier, the control circuit for which employs logic signal development using timer techniques dependent on the amplitude of voltage deviation from the intended regulated output level. Each of two low voltage sections employs a power switch controlled by sampling and pulse steering techniques to effect fixed high frequency, variable duty cycle switching. An inhibit input is supplied from each of the low voltage sections to the high voltage section to prevent a high voltage output to the load in the absence of low voltage development.
