Title: Apparatus for cutting and metering slabs or bales of unvulcanized rubber
IPC: B29B15/02
Filed: 1979-07-31
Abstract: Apparatus is provided for cutting and metering slabs or bales of unvulcanized rubber to be fed to a single rubber mixing machine. The apparatus includes a conveyor belt and a carriage arranged to transport bales of rubber along parallel paths. A cutting machine is positioned to cut a slice off a bale carried by said carriage. By arranging for the carriage to undergo back and forth movement while intermittently effecting transverse feed of the bale, the cutting machine cuts a succession of slices off the one bale. To make up a load of rubber of a required weight, whole bales are transferred to a hopper via the conveyor belt until a weighing machine indicates that the required weight has almost been reached thereafter the cut slices of rubber are added to the hopper under the control of the weighing machine to make up the weight required.
Patent ES-485701-A1 (ES)
Title: Method of forming s-z twisted strand units
IPC: H01B13/04
Filed: 1979-11-05
Abstract: Method for forming strands (16, 18) into twisted strand units having a twist direction that reverses from section to section wherein the strands are advanced side-by-side successively through first and second mutually spaced twister heads (30, 32). The strands are formed into twisted strand units by the steps of operating the twister heads simultaneously by revolving the twister heads in a common rotary direction (36, 36) about the strands at substantially the same speed of head revolution thereby causing a first progression of twists (A) of one lay direction to pass from the first twister head (30) towards the second twister head (32), and a second progression of twists (C) of opposite direction lay to eminate from the second twister head. Twisting operations by the first and second twister heads are simultaneously terminated as the leading end of the first progression of twists reaches the second twister head and a trailing end of the second progressing of twists eminating therefrom. Twisting operations of the first and second twister heads are then suspended until a trailing end (B) of the first progression of twists reaches the second twister head (Fig. 4) whereupon the foregoing steps are repeated.

Title: Stem processing for data reduction in a dictionary storage file
IPC: G06F3/02
Filed: 1980-01-04
Abstract: A system for reducing storage requirements and accessing times in a text processing machine for automatic spelling verification and hyphenation functions. The system includes a method for storing a word list file and accessing the word list file such that legal prefixes and suffixes are truncated and only the unique root element, or "stem", of a word is stored. A set of unique rules is provided for prefix/suffix removal during compilation of the word list file and subsequent accessing of the word list file. Spelling verification is accomplished by applying the rules to the words whose spelling is to be verified and application of the said rules provides, under most circumstances, a natural hyphenation break point at the prefix-stem and stem-suffix junctions.

Title: Housing assembly for split crankcase radial compressor
IPC: F04B27/053
Filed: 1981-01-20
Abstract: A housing assembly for a scotch yoke radial compressor especially adapted for use in automotive air-conditioners having a cast crankcase which is split along a plane axially passing through the center lines of the radially oriented cylinders. Each half of the crankcase has a plurality of radially extending semi-cylindrical recesses which, when assembled, form the cylinders. A steel outer housing encloses the crankcase and serves to form the intake and outlet chambers. The housing is formed of two halves which are joined together along a fluid-tight interface and additionally strengthened by means of a plurality of tie rods which pass through openings in the crankcase and clamp the housing halves tightly together. The tie rods pass through eyelet rivets disposed within the openings in the crankcase. The rivets are clinched so as to secure the crankcase halves together and seal the interface between the crankcase halves in the area of the tie rod openings. The eyelet rivets also serve to provide a guide for the tie rods during assembly for ease in mating the two halves of the housing.

Title: Method of correcting erroneous values of samples of an equidistantly sampled signal and device for carrying out the method.
IPC: G11B5/09
Filed: 1984-12-04
Abstract: The values of incorrect samples of, for example, a digital audio signal are estimated by means of interpolation. For this purpose an appropriate sampling interval is determined from the number of incorrect samples, in which interval the incorrect samples are situated. Subsequently, a best-fitting recursion formula is determined from the values of the samples, a first estimate being taken for the values of the incorrect samples. By means of this recursion formula the value of a sample is expressed as a weighted sum of the values of a number of preceding samples and an error term. By means of the recursion formula thus found the values of the incorrect samples are subsequently estimated, in such a manner that they are best-fitting values for the recursion formula. The Application also discloses a device for carrying out the method.

Patent ES-8608679-A1 (ES)
Title: Method and apparatus for the detection of reducing gases.
IPC: G01N21/3504
Filed: 1985-04-03
Abstract: Reactive gases like, for example reducing gases, specifically carbon monoxide, are detected in a gas mixture, particularly in air, with extremely high sensitivity and with high precision using a gas detector in which the attenuation of the intensity of an infrared radiation beam by a catalyst layer is utilized. Such catalyst layer contains at least one transition metal selected from at least one of the groups I, VII, and VIII of the Periodic Table of the Chemical Elements. Preferably, chemical elements are used having an atomic weight in the range of about 100 to about 205. The detection of carbon monoxide is particularly sensitive using a catalyst layer which substantially contains a metal capable of forming a carboncarbonyl compound with carbon monoxide. The sensitivity and precisionof detecting carbon monoxide and other reducing gases can be significantly increased by periodically exchanging the gas mixture to be investigated in a measuring chamber and replacing it with a pure reference gas from a reference chamber. The sensitivity and precision of the gas detection can be further increased by periodically alternating the temperature of the catalyst layer during such period of gas exchange. The alternating signal this obtained at an output of the gas detector can be evaluated for determining the concentration of the reactive or reducing gases in the investigated gas mixture.
