Patent ES-391292-A1 (ES)
Title: Spring-applied disc brake
IPC: F16D65/14
Filed: 1971-05-18
Abstract: A disc brake is disclosed which has a spring actuator in addition to the usual hydraulic actuation. When the brake is functioning normally, fluid pressure opposes the spring actuator to permit normal hydraulic operation of the brake. However, when fluid pressure is not available to the brake, because of a malfunction or because the vehicle operator has closed a valve to isolate the brakes from the vehicle's hydraulic system, the spring actuator maintains the frictional elements engaged with the rotor. The spring actuator, therefore, functions as both a parking brake and a fail-safe brake that immobilizes the vehicle when a malfunction in the vehicle's hydraulic system occurs. Mechanical release means are provided to release the spring actuator to permit the vehicle to be moved if the spring actuator has applied the brake while the vehicle is standing in an inconvenient location.

Patent ES-422141-A1 (ES)
Title: Method for continuous displacement washing of liquid-containing pulp materials
IPC: D21C9/06
Filed: 1974-01-09
Abstract: Liquid-containing pulp material, especially sulphate pulp containing black liquor, is deposited as a mat on a moving filter and subjected to displacement washing with a liquid such as clean water supplied to one side of the pulp mat and displacing the black liquor, which emerges in substantially undiluted form from the opposite side of the mat. The filter is a screen moving over a supporting floor, said floor and screen together forming a "resistance floor" providing a substantial flow resistance to the liquid. A layer of displacement or washing liquid (e.g., water) is maintained over the pulp mat covering the surface thereof. This layer may have a depth or height of e.g. 10 to 100 cm, thus protecting the surface of the mat against the effect of supply means for displacement liquid and providing a pressure on the upper side of the pulp mat assisting in overcoming the flow resistance of the pulp and the floor.

Patent ES-438703-A1 (ES)
Title: Method of aseptically connecting a fitting to an aseptic storage tank
IPC: A23L3/34
Filed: 1975-06-19
Abstract: A method of connecting an aseptic fitting to an opening in the top of an aseptic bulk storage tank, whereby asepsis of the tank interior is maintained. The method includes the step of filling the tank interior with liquid chemical sterilant sufficiently to overflow sterilant from the tank into a liquid-retaining enclosure which surrounds the opening in the tank top. This is effective to both sterilize the interior of the tank, and provide a liquid sterilant bath in contact with the openings. The method further includes immersing the fitting in the sterilant bath to sterilize it, and while immersed and in a sterile condition, connecting it to the tank opening, thereby isolating the sterile tank interior from the environment with a sterile fitting. If the fitting includes an internal cavity, sterilization of the fitting prior to its immersion in the bath and connection to the tank can be done by capping the fitting to seal the cavity and autoclaving it. The capped fitting which has been sterilized remote from the sterilant bath is then immersed in the sterilant bath and while immersed connected to the tank opening, to thereby establish communication between the cavity of the fitting and the tank interior while both the cavity and the interior are maintained in a sterile condition.
