Title: Segmental precast concrete post-tensioned overpass bridges with cantilevered abutment
IPC: E01D2/04
Filed: 1972-06-04
Abstract: A bridge structure particularly adapted for construction in skewed orientation with respect to a lower, overpassed roadway comprises a bridge portion, end abutments, and an intermediate support column. The bridge portion is constructed by supporting a plurality of precast concrete open-topped box-beams and precast L-shaped parapet-sidewalk members on temporary falsework at the bridge site. Upstanding from the precast box beams are wooden flanges which are trimmed in place to provide temporary supports of desired heights for precast slabs forming a bed for the upper roadway. The variable-height supports are used to form a crown in the roadbed, or to form an inclined roadbed which may be part of a banked curve. The precast box-beams are joined together by formed-in-place concrete diaphragms which are poured simultaneously with a concrete roadbed, whereby a monolithic squared off bridge portion is formed. An intermediate support column engages one of the diaphragms, thereby eliminating an exposed transverse support beam. The bridge portion is post tensioned by means of longitudinal and transverse post tensioned tendons.

Patent ES-431220-A1 (ES)
Title: Process for separation of monocarboxylic acids from a mixture of monocarboxylic, hydroxycarboxylic and dicarboxylic acids
IPC: C07C69/00
Filed: 1974-10-22
Abstract: In a process for producing esters of carboxylic acids from the waste salt solutions derived from the manufacture of cyclohexanone, the mixture of organic acids obtained by acidulation with a strong acid and separation of an inorganic salt solution is refined to separate the monocarboxylic acids from the hydroxycarboxylic and dicarboxylic acids by a three-stage distillation at a temperature lower than 120 DEG C. The first stage is performed at a moderate vacuum, the second stage at a higher vacuum and the third stage is a steam distillation stage at a moderate vacuum, with the steam requirements reduced by returning to the evaporator an aqueous phase that is readily separated from the distillate. The use of steam in this manner only in the third stage reduces the steam requirements to economic proportions. More than 99% of the monocarboxylic acids may be separated from the other carboxylic acids in this fashion.
Patent ES-438643-A1 (ES)
Title: Dispensing closure for a container
IPC: G01G19/22
Filed: 1975-06-17
Abstract: A dispensing closure for a container for dispensing metered quantities of powder contents and the like therein and having an outer tubular element having a tubular body with an inclined bottom wall that terminates in an upstanding wall spaced from an inner wall surface defining a bottom inlet for communication with the interior of the container. A second element comprising a split cylinder is disposed axially in the outer tubular element and has a top defining an outlet opening on the outer tubular element. The second element has a wall in the tubular body spaced axially from the bottom wall and inwardly from the upstanding wall to define a chamber having an opening communicating with the bottom inlet opening. A second chamber is formed between the first-mentioned chamber with which it communicates and the bottom wall. The wall of the second element defines an outlet communicating with the second chamber and the top outlet opening. If the container is inverted from the upright a quantity of the contents enters the tubular element into the first-mentioned chamber. Upon return to an upright position this quantity of contents is retained in the second chamber and upon reinverting of the container it is dispensed through the top opening and a similar quantity of contents is introduced into the first-mentioned chamber for subsequent metered dispensing.

Patent ES-454890-A1 (ES)
Title: Bar handling system
IPC: B21D43/28
Filed: 1977-01-07
Abstract: This system is intended to make it possible, with increased cutting-shears capacity, to feed the concrete-reinforcement bars, which are to be cut, from storage beds (1), starting from a position which is appropriate for cutting, to cutting shears (10). Due to their considerable length of up to approximately 20 m, the concrete-reinforcement bars are often located in the storage beds in an oblique manner in the vertical and horizontal directions and are thus not appropriate for cutting. The concrete-reinforcement bars to be cut are moved, by means of a removal device, that is to say, for example, in bundles by means of a winch, onto a longitudinal conveyor and store which is located parallel to the storage beds (1) and extends in the longitudinal direction of the concrete-reinforcement bars. The longitudinal conveyor and store may be a rolling path (5). It can be oriented in an aligned manner on a cutting-shears path (2) within which the cutting shears (10) are arranged. By means of, for example, driveable rollers (6), then in each case as many concrete-reinforcement bars can be conveyed onto the cutting-shears path (2) as are to be cut by means of one cut of the cutting shears (10). Thereafter, the cutting is carried out by the cutting shears (10). The cut concrete-reinforcement bars are subsequently conveyed from the cutting-shears path (2), for example by means of transverse conveying means (15), onto a collecting path (3) and, from there, are conveyed away. It is essential that, in this manner, concrete-reinforcement bars are fed to the cutting shears always in a position and number appropriate for cutting.

Title: Weaving machine with heddle frames
IPC: D03C1/14
Filed: 1978-10-04
Abstract: The invention relates to a weaving machine having plural heddle frames, into which heddles are threaded with a free floating characteristic or operational clearance onto thread rails. The heddles are arranged on the thread rails with the least possibility of movement and without a free floating capability during a portion of the heddle frame movement and with a free floating characteristic during the rest of the movement of the heddle frame to facilitate a self-alignment of the heddles with the warp threads. The free floating characteristic is initiated by periodically reducing the distance between the two thread rails.
