Patent ES-475399-A1 (ES)
Title: Hydraulic system with an open centre valve and a power assisted steering gear incorporating the system.
IPC: B62D5/08
Filed: 1978-11-24
Abstract: An hydraulic system: a power assisted vehicle steering system which includes such an hydraulic system and a method of alleviating noise in an hydraulic system. The hydraulic system as applied to a vehicle steering gear (1) has an open center valve (3) which directs hydraulic fluid under pressure derived from a pump (12) and in response to a steering maneuver through a shaft (4) to a servo motor of the gear (1). Downstream of the open center valve (3) is a restrictor (8) through which hydraulic fluid from the valve (3) passes to a reservoir (11). The restriction effected by the restrictor (8) to fluid flow from the valve (3) to the reservoir is variable to provide a throttling action and a back pressure in the line (6) to alleviate noise in the valve (3).

Title: Mechanism for closing egg containers
IPC: B65B23/04
Filed: 1979-03-09
Abstract: Rod-like tools mounted on gears so as to be swung together and apart by a reciprocating drive and running across a conveyor intermittently moving loaded egg containers, likewise oriented across the conveyor, are moved together to fold over the top corrugated strips of the upstanding sides of the egg container, as presented to the machine, by 90 DEG , to bring these strips into abuttment. Each corrugated strip is backed by a flat strip and one of the two has tabs which are folded over by 180 DEG and adhesively bonded to the other flat strip. The folding over of the tabs is performed by a set of fingers that move between segments of the first-mentioned folding tools to raise the tabs at an oblique angle, after which push rods bend them over completely. During these operations adhesive is applied to the surfaces to be bonded so that the tabs will hold the container together after the first-mentioned folding tool and the finger and push-rod assembly are moved back out of the way of the transport path of the container so that the containers on the conveyor can proceed to the next station.

Title: Steam-heated metal plate floor for precasting bed - is fixed at single alternative points to limit product cracks due to floor expansion
IPC: B28B23/06
Filed: 1979-03-30
Abstract: The heated one-piece sheet metal floor (120) is used in the fabrication of precast prestressed concrete beams or similar, constituting the soffit form for the precast products, and being mounted over a pit (124) contg. pipes (121) feeding steam. A battery of side forms is used with the floor, being fixed in place to obtain longitudinal lines of moulds. The floor is free to move relative to the substructure (100), clamp-action fasteners being utilised to anchor it at one of two or more alternative points. The system avoids cracking of the products due to thermal movement of the floor, the particular anchorage utilised being located within the length of a product under consideration. The fasteners may be of a two jaw clamp type, a movable jaw (108) being displaced by a jack to grip a longitudinal edge of the floor.

Title: Control apparatus for the electromagnetic brake of a weaving machine
IPC: D03D51/08
Filed: 1981-07-23
Abstract: A control apparatus for the electromagnetic brake of a brake device or unit of a weaving machine or loom comprises a cam-controlled brake-pulse transmitter rotating with the machine shaft and two continuous signal switching stages which act upon two parallel connected AND-gates or circuits, each having connected thereafter an adjustable or regulatable time-delay element.

Title: Method of removing scale.
IPC: C02F5/08
Filed: 1983-12-29
Abstract: A method of removing adherent scale from the internal surfaces of water heating, cooling or circulating systems such as boilers, cooling towers and the like. A descalant comprising a polyacrylate or a polymethacrylate, within a certain molecular weight and concentration range, is mixed with the water in the system and is circulated through the system for a period effective to dissolve the scale adhering to the surface. The descalant is used in a concentration which is effective both to dissolve the scale, and to permit the descalant itself to remain in solution after the scale has been dissolved. For scale remover having a molecular weight in the range of about 500 to about 100,000, the effective concentration is from about 125 ppm to about 1,000 ppm and preferably is from about 500 ppm to about 550 ppm. A preferred descalant is the sodium salt of polyacrylic acid having a molecular weight in the range of about 1,000 to 10,000 and used in a concentration in the range from about 500 to about 550 ppm.
