Patent ES-432270-A1 (ES)
Title: Waterproofing of textiles
IPC: D06M15/227
Filed: 1974-11-26
Abstract: This invention relates to the treatment of fibrous materials such as textiles to make them water-repellent. It has been found that the amount of organopolysiloxane used in treatment baths for those purposes can be considerably reduced by replacing up to 70% by weight of the emulsified organopolysiloxane with 30 to 65% by weight of the replaced organopolysiloxane of an emulsified oxidized polyethylene. Even though oxidized polyethylene does not by itself impart water-repellent properties to textiles its combination with the organopolysiloxane does give treated fabrics with excellent water-repellent properties.
Patent ES-438270-A1 (ES)
Title: Impact crusher with adjustable impact or grinding means
IPC: B02C13/09
Filed: 1975-06-05
Abstract: An impact crusher wherein hard particulate material is comminuted during travel between a rotor provided with beaters and a pivotable impact or grinding means, the latter being mounted in the housing of the crusher at a level above the rotor and tends to pivot by gravity and/or by spring force in a direction to reduce the width of the gap between its lower portion and the periphery of the circle swept by the rotor beaters. The impact or grinding means is pivotable by feed screws which are articulately connected thereto and extend upwardly through openings in the top wall of the housing. The outer portions of the feed screws are rigid with a crosshead which can be moved up and down by a double-acting hydraulic cylinder and piston unit which has an appropriate lost motion to allow the impact or grinding means to yield in direction away from the rotor. When the cylinder and piston unit lifts the crosshead, additional cylinder and piston units can readily shift stepped or wedge-like inserts which are movable between the crosshead and the top wall of the housing to thereby determine the minimum width of the gap. The inserts can be engaged directly by the underside of the crosshead or by a platform which can be mounted beneath the crosshead. When the adjusting mechanism for the impact or grinding means employs a platform, packages of dished springs are inserted between the platform and the crosshead.

Patent ES-455385-A1 (ES)
Title: Digital interface for resynchronizing digital signals
IPC: H04Q11/04
Filed: 1977-01-27
Abstract: An elastic interface is disclosed for two communicating digital carrier systems autonomously synchronized to disparate time bases independent of each other in frequency and phase. The interface includes two arrangements, one for each direction of transmission between the two digital systems. In an illustrative application for the interface in a telephone system, the first of the two digital systems is a digital transmission system while the second is a time-division-multiplex switching network. The different internal constraints of each system call for digital signals at variance in sampling rate and code format. The interface amply satisfies the difference in sampling rate by an interpolation process which supplies the requisite number of intermediate encoded signal samples. Code conversion techniques are employed to match the code format of each digital system. Flexibility in the interpolation process is provided by adjusting the value of the encoded samples in response to changes in the relative time intervals between each encoded sample being supplied to one digital system and the encoded samples from the other digital system upon which it is derived. The digital signal medium established in the interface preserves the quality of the information traversing the medium as the digital signals coupled thereto undergo a change in sampling rate even though the autonomous operation of each of the two digital systems occasions relative frequency drift between the time bases of the two digital systems.

Patent ES-459776-A1 (ES)
Title: High speed ball header
IPC: B21J9/06
Filed: 1977-06-14
Abstract: A ball header is disclosed in which the movable die is mounted directly on the machine frame rather than on the reciprocating slide. The position of the movable die is controlled by a cam driven pusher so that the movable die position is dependent of the position of the reciprocating slide. The machine provides a greater portion of the machine cycle for the movement of the transfer from between the dies after the blank is gripped and controlled by dies. The machine further provides a closed or bushing cutter to improve the shearing of the blanks from the wire stock so that the part formed by the machine can be closer to the finished size of the product to reduce the material content and the cost of finishing operations. The accuracy of the positioning of the movable die is also improved by the mounting of the movable die directly on the frame rather than on the reciprocating slide.
