Patent ES-418904-A1 (ES)
Title: Continuous molding conveyor with side clamping and release
IPC: B29C48/90
Filed: 1973-09-19
Abstract: Plastic is foamed in a pressure tunnel portion of a molding conveyor formed by opposed endless conveyor runs with side pieces defining the product cross section. One or both employed the endless runs, preferably the bottom conveyor run is laterally split into at least two separate endless shiftable conveyors respectively carrying the side pieces forming the sides of the pressure tunnel, which shiftable conveyors are laterally movable, with respect to the conveying or molding direction, at the tunnel entrance and the tunnel exit for clamping and unclamping respectively, that is for bringing the side pieces horizontally toward each other transverse to the molding direction to form the final configuration for the tunnel cross section and away from each other at the molding tunnel exit to release the sides of the molded product. This clamping and unclamping of the side pieces is particularly important with molded sheets having a configured edge so that the side pieces may be constructed with a corresponding configuration. Preferably, the two shiftable endless conveyors are constructed of a series of plates having pivotal connections therebetween to form a chain, which connections will allow additional sliding or shifting of the plates with respect to each other within a limited range, preferably under the control of guide means on the individual plates and stationary support structure. Preferably, the guide means are rollers on the plates engaging within stationary tracks. A flexible cover endless belt may be employed to bridge the joint between the shiftable endless conveyors and form the entire bottom surface for the tunnel portion. After the lower shiftable conveyors have been moved toward each other to their final tunnel configuration, a flexible endless belt may be tightly brought into contact with the tops of the side pieces and clamped by the upper rigid endless conveyor, so that through the unsupported tunnel portion, the upper belt will be tightly held at its opposite ends and not subject to sagging while forming a smooth continous upper wall for the molding pressure tunnel.

Patent ES-424152-A1 (ES)
Title: Pressurized-water reactor coolant treatment system
IPC: G21C7/22
Filed: 1974-03-11
Abstract: A pressurized-water reactor coolant treatment system continuously removes a portion of the coolant circulating in the main coolant loop and passes it through a gas separator and a rectification column, among other equipment, and returns the coolant to the main coolant loop. By passing the removed coolant first through the rectification column and thereafter through the gas separator and providing means for controllably shutting off the separator and bypassing the removed flow around the gas separator for passage of the flow from the rectification column back to the loop, it is possible to subject the coolant to both rectification and degassing when the coolant requires such treatment, and when the coolant does not require degassing to shut down the gas separator and put it out of operation. Other features are included.

Patent ES-479443-A1 (ES)
Title: System for transmitting optically linked electrical signals and device for the automatic gain control of a receiver path connected to this optical linkage.
IPC: H04B10/00
Filed: 1979-04-09
Abstract: A fiber-optical communication path between a transmitter and a receiver of electrical message signals forms a main channel and a shunt branch terminating at respective photodiodes from which incoming signals can be alternatively fed to an output terminal by way of an adjustable attenuator that is periodically reset, with the aid of a digitally operating automatic-gain-control loop in response to a pilot signal arriving over the same path. A code converter in that loop supplies binary words, representative of signal amplitude, to a comparator which determines whether the amplitude of a signal in the output of the main channel exceeds a given threshold and, in that case, causes a switchover to the shunt branch whose optical attenuation is substantially greater. The periodic emission of a pilot signal in lieu of a message signal is controlled by a setting instruction which, aside from enabling the resetting of the attenuator according to the instantaneous contents of the code converter, is sent to the transmitting end via a further fiber-optical channel in order to command a changeover from one signal source to another.

Patent ES-484285-A1 (ES)
Title: Hydrostatic support member
IPC: F16C32/06
Filed: 1979-09-19
Abstract: In a hydrostatic support member with at least one pressure pocket in the head portion of the support member, the or each pressure pocket opening opposite a surface which is to be supported, the inner side of the lining wall which defines the pressure pocket relative to the environment of the support member is inclined relative to the pressure axis of the support member, so that the profile of the pressure pocket becomes larger towards its base. The outside of the lining wall extends relative to the inner side in such a way that when this wall is lowered towards the base the hydrostatically effective surface of the head portion, facing the surface which is to be supported, increases in size. A method of producing or finishing the support member according to the invention is proposed: The support member is first prefabricated with the head portion having a relatively small hydrostatically effective surface, compared with an operational one, the walls having been made higher. It is then used under conditions which simulate actual operation. The prefabricated walls of the at least one pressure pocket being so lowered by a lapping type process. As the hydrostatically effective surface of the head portion increases in size during this lowering, the lapping stops automatically at the stage when the optimum operational hydrostatically effective surface for the head portion has been obtained.
