Title: Ethylene copolymer compositions, process for the preparation and use thereof.
IPC: C08L101/00
Filed: 1979-02-21
Abstract: A process is described for preparing compositions comprising ethylene copolymers, such as ethylene-acrylate or ethylene-vinyl acetate copolymers, and compatible liquid hydrocarbons which act as inexpensive plasticizers or extenders, the process enabling large quantities of inert, e.g. inorganic fillers to be incorporated more simply than previously proposed processes. The hydrocarbon is compatible if it satisfies the test that there is no observable exudation of hydrocarbon from the copolymer when 50 g. of powdered copolymer are mixed with a quantity of hydrocarbon in a metal dish which is first heated to 120 DEG C. to fuse the copolymer, second cooled and held at a temperature of -20 DEG C. for 18 hours, and third warmed to room temperature. The compositions may be prepared either in the form of free-flowing powders or aqueous dispersions both of which are described and both of which have advantages when used in described situations as hot melt adhesives or coating compositions, especially for carpet backing techniques.

Patent ES-8202737-A1 (ES)
Title: Control valve device for pneumatically operated servomotors.
IPC: B60T13/57
Filed: 1980-01-31
Abstract: A control valve for a servomotor having a disc located in a bore of a hub attached to a movable wall. The movable wall separates a first chamber from a second chamber. A passage in the disc connects a first passageway with a second passageway in the hub to define a flow path to allow free communication of a first fluid between the first and second chambers. A plunger located in the bore has a first end with an axial projection extending therefrom which engages the disc and a second end connected to an input push rod. An input force applied to the push rod moves the plunger which causes the axial projection to deform the disc and interrupt the flow path between the first and second chambers. Thereafter, further movement of the plunger allows a second fluid to be communicated to the second chamber whereby a pressure differential is created across the wall by the first and second fluids. The pressure acting on the wall creates a force which moves the wall and provides an output member with an operational force.

Patent ES-8306230-A1 (ES)
Title: Steering valve.
IPC: F16D49/12
Filed: 1981-10-23
Abstract: The invention relates to a distance-dependent control valve (77), particularly for controlling a belt brake. The piston rod (65) of an hydraulic cylinder (63) is displaceable against the action of a spring (95) and connected to a control rod (45) which is applied to a belt brake (11).

Title: Improved method and apparatus for mass flow measurement.
IPC: G01G11/00
Filed: 1982-02-17
Abstract: Apparatus and method for mass flow measurement including means (25) for rotationally oscillating a substantially curved, preferably U-shaped conduit (14), solidly mounted in a cantilevered manner at the open ends of the legs (18, 20), and equipped with sensors (33, 33', 34, 34') which measure acceleration, velocity or position of each side leg (18, 20) of the conduit (14). The sensors (33, 33') are preferably velocity sensors, being each a magnet (42) and a coil (45). The coil (45) is translated in the uniform portion of the magnetic flux field, and the sensors (33, 33') produce analogue signal output which accurately correspond to the motion of the adjacent leg (18, 20). In the event of flow through the conduit (14), a change from coincidence in the time relationship of the two sensor signals relative to the divergent oscillations of each side of the conduit (14) caused by mass flow is measured in both directions of oscillation. Mass flow is determined as a function of such time separation of the signals.

Title: Apparatus for separating agglomerated particulate matter
IPC: F27D25/00
Filed: 1982-04-14
Abstract: Apparatus for breaking apart agglomerations of particulate matter flowing in a vessel (particularly useful ina pressurized moving-bed vertical-shaft reduction reactor for the production of sponge iron) is exemplified by an externally mounted hydraulic cylinder having access to the interior of said vessel through a probe port, the piston of said hydraulic cylinder being provided with a conical probe positioned so as to be normally retracted out from the interior of said vessel but extendable by said hydraulic cylinder into and across the interior of said vessel, preferably at the narrowed discharge portion thereof, whereby said probe is angled to extend downwardly in the direction of flow of said particulate matter as well as across said flow to engage and break up any agglomerations of particulate matter in its path. When used with a pressurized vessel, the probe may be uniquely adapted to function without reactor pressure loss by a housing for the probe, or alternatively for the entire probe and hydraulic cylinder, with said housing having open communication with said vessel, so as to minimize sealing problems with respect to the moving probe. In a reduction reactor, the probe is preferably mounted near the bottom of the cooling zone adjacent the narrowed discharge outlet so as normally to be retracted to avoid any obstruction of the uniform flow through the reactor, and yet be angled along and across the direction of flow to assist in the discharge and also intercept and break up agglomerations obstructing the narrowed discharge.
