Patent ES-456770-A1 (ES)
Title: Method and device for cutting and shaping a sheet or slab of paste based in particular on clays for making ceramic objects
IPC: B28B3/02
Filed: 1977-03-11
Abstract: A method of cutting and shaping a sheet or slab of soft, tearable and scalable paste, constituted for example by agglomerated solid or plastic particles, based in particular on clays, for the manufacture of ceramic objects or pieces, said objects being cut out of a slab portion constituting a blank by means of suitably contoured cutters which are caused to penetrate into the said paste laid on a bearing support having the desired shape, after which the trimmings are removed. In order to allow the objects cut out of the said blank to be recovered, the said cutting is performed on a supple film or hand laid on the said support, for example a plastic film or sheet, which is apt to conform in shape to the objects cut out, which does not adhere to the said objects and which is not cut by the said cutters, the objects thus cut out being thereafter separated from the said supple band.

Title: Power steering mechanism control valve
IPC: B62D5/08
Filed: 1977-08-18
Abstract: A steering control valve and worm nut centering device for a power steering booster mechanism control valve is provided comprising a flexure rod carried either by the double-acting piston member or the worm nut member and extending between those members or into the valve spool. The overall construction is conventional and well known, the particular feature of the invention being a flexure rod which is adjustable translationally or rotatively, in various modifications, to center the valve spool of the control valve and to center the worm nut. The flexure rod can be predetermined as to length, taper, alloy, and other design factors so as to flex to give a desired increase in road resistance feel substantially over and above that afforded by the usual size of reaction chambers and centering spring conventionally associated with the valve spool. Thus, a flexure characteristic curve of extent of flexure versus degree of steering provides a sharp increase in road resistance simulation as the steering spindle is turned.

Title: Gas-heated appliance
IPC: F23N5/20
Filed: 1979-08-02
Abstract: The appliance comprises a gas burner (12) for heating e.g. water in a heat exchanger (15), with the exhaust gases being force vented by a fan (17) driven by a motor (41) and the gas supply controlled by a signal representing heat demand by a solenoid value (11).

Title: Betaine recovery process.
IPC: C13B20/14
Filed: 1981-02-27
Abstract: Betaine is recovered from natural sources such as beet molasses, rest molasses and vinasse by diluting the molasses to 25-50% solids, introducing the molasses to the top of a chromatographic column containing a salt of polystyrene sulfonate cation exchange resin crosslinked with from about 2 to about 12 weight percent of divinylbenzene, eluting with water and collecting a fraction of betaine from the downstream side of the resin.
