Title: Device for winding up a belt or web
IPC: B60R22/44
Filed: 1977-04-23
Abstract: A dispenser for a retractable safety belt, to be used by the driver of a vehicle, comprises a holder in which a roller loaded by a retraction spring is journaled. The belt, anchored to the roller and partly wound around it, coacts with an insert in the form of a resilient ribbon which is coiled with the belt about the roller during at least an initial phase of a pull-out stroke and about a collateral axis alongside the belt during at least a final phase of that stroke of exert upon the belt a supplemental biasing force which either aids the force of the retraction spring in the initial phase or opposes it in the final phase. The changeover between the two phases can be brought about by a beginning windup of the free ribbon end, by a diversity of inherent stress in two longitudinally adjoining ribbon sections, or by a detent responsive to the coil diameter which holds the ribbon away from the belt in the final phase of pull-out and lets it rejoin the belt at an intermediate stage of the retraction step.

Patent ES-462687-A1 (ES)
Title: High frequency diffusion muffler for gas jets
IPC: F16L55/027
Filed: 1977-09-27
Abstract: A dissipative-type muffler for attenuating the high velocity discharge of a high pressure-high temperature safety valve. A path of flow constituting four stages of controlled turbulence suppressed diffusion is formed internally of the muffler extending from an intake into a plenum chamber then distributed past a plurality of parallel arranged radial diffuser flanges and an acoustical liner before exiting to atmosphere at relatively low velocity and low noise level. Laminar flow to small scale turbulence is obtained in the first stage by a jet impingement directional reversal in a controlled spacing discharge from an intake pipe within the plenum chamber. In the second stage, small scale discharge turbulence of high frequency is achieved by laminar flow induced via radial diffusion through controlled gap spacings between the diffuser flanges. Buffer plate impingement of the second stage discharge is then effected in the third stage after which high frequency noise attenuation by means of an acoustical composition is obtained in the fourth stage before exiting to atmosphere.

Patent ES-465750-A1 (ES)
Title: Compressed fluid source.
IPC: F15B/
Filed: 1978-01-03
Abstract: This Compressed Fluid Source works in the following manner: a fluid is introduced into receptacle 1 through pipe 5. The fluid intake is regulated by a valve, and then a sliding screw, wheel or nut begins the process of compressing the fluid using a simple screw mechanism, penetrating and occupying space and forcing the fluid to become compressed. The compression is studied from the outside on the scale, 2. When the sliding wheel or screw, 4, has occupied sufficient space by turning and penetrating or exerting pressure on the liquid so as to guarantee sufficient compression free of danger, the screw is locked into position. When it is necessary or convenient to use the compressed fluid for a Pneumatic motor, 5 and 6 are connected to the desired fluid user. The operation may be repeated or carried out in duplicate either simultaneously or in an alternating manner, using the other sliding wheel or screw, 9. The Pneumatic Compressed Fluid Source may reuse the fluid already used for compression as well as by a pneumatic motor for producing energy. It is therefore an inexhaustible, non-polluting and economical source of energy that greatly reduces the risk of fires and explosions.
