Patent ES-386337-A1 (ES)
Title: Yarn clamping and cutting attachment for circular knitting machines
IPC: D04B15/61
Filed: 1970-12-11
Abstract: An auxiliary clamp to hold an elastic yarn in combination with a conventional yarn cutting and holding mechanism of the type used on a circular hosiery knitting machine and in which pneumatic means is used to hold the yarns. While the pneumatic means is capable of holding the ends of non-elastic yarns it is not capable of holding the ends of elastic yarns. The clamp is self-acting and provides a wedge shaped opening to hold the elastic yarn, the opening being defined by a flat surface of the conventional mechanism and by a straight edge of a plate member disposed at an angle to the flat surface. The elastic yarn is forced into the wedge shaped opening of the clamp by the movement of the inactivated elastic yarn itself as the last needle taking the same moves around the machine.
Patent ES-404910-A1 (ES)
Title: Digital register readout circuit
IPC: H04Q3/54
Filed: 1972-07-15
Abstract: A register readout circuit arranged for use with common control switching systems wherein number digits are stored and serially read out at a high speed into a common controller. The circuitry utilizes binary ripple counters having a predetermined number of counting states to register each number digit. During the readout sequence, the common controller applies a high speed pulse train having a number of pulses equal to the number of counting states to each counter. When the counters are advanced to their initial zero counting states associated logic circuitry is enabled to gate remaining pulses of the high speed pulse train over digital leads to the common controller. Since the remaining pulses are mathematically equal to the registered number digits of the counters their reception by the common controller effectively constitutes a nondestructive readout of the registered number digit.

Title: Apparatus and method for manufacturing cores and molds with static mixer stage
IPC: B22C15/23
Filed: 1976-04-21
Abstract: An apparatus and method for forming foundry cores and molds of superior hardness and uniformity in a wide range of sizes includes staging hoppers for storing a first mass of sand coated with a catalyst-polymerizable resin film, and a second mass of sand coated with a catalyst film for polymerizing the resin. In forming the cores or molds these masses are simultaneously and evenly dispersed into a high velocity carrier air-sand stream and directed through a static mixer stage, wherein the resin and catalyst-coated sand particles are intermingled and at least a partial integration of the films takes place, into a shaping mold cavity, wherein the sand mixture hardens into a desired shape. Because the process is fast and continuous and mixing is accomplished without mechanically driven mixing elements, the apparatus and method are particularly well suited to high volume foundry operations wherein resin-catalyst systems having very fast hardening times are utilized.

Title: Front feed static screen
IPC: B01D35/28
Filed: 1977-10-04
Abstract: A static screen separator compact in both a vertical and a horizontal sense, including an inclined screen structure and a facing feed or head box from which a liquid-solids mixture overflows onto the screen.

Abstract: A hot and cold water sanitary mixing set, comprises a housing having a flow control chamber with a central outlet passage connected from the control chamber to the outside of the housing and with separate hot and cold water supply passages connected into the bottom of the control chamber. A control valve assembly is mounted in the chamber and it comprises an assembly of discs which are arranged in superposed relationship so that one or more of them is movable relative to the others under the control of a single lever which is pivotally mounted in the housing and engages the control disc assembly to move them for control of the flow. The control valve assembly comprises at least three separate superposed discs including a bottom disc having a central discharge passage which overlies the central outlet and provides a flow passage for the discharge of a mixed quantity of water therethrough. The bottom disc has separate bottom hot and cold water passages defined therethrough which are alignable over the respective hot and cold water supply passages for the passage of the respective hot and cold water therethrough. An intermediate disc has an intermediate hot and cold water passage defined therethrough and is movable relative to the bottom disc to align a selected area portion of the respective intermediate hot and cold water passages with the selected area portion of the bottom hot and cold water passages so as to control the volume of the flow therethrough. A feature of the construction is that the top disc or an associated part of the top disc defines a recess above the intermediate disc which forms a through passage for the passage of the water from the respective hot and cold inlet passages into the discharge passage. The top discs are advantageously formed with baffle means or projections to extend into the through passage so as to provide interruptions therein which reduce the flow turbulence and noise of the mixing water.
