Patent ES-345270-A1 (ES)
Title: Methods of deep drawing solid plastic materials
IPC: B21D22/20
Filed: 1967-09-09
Abstract: method of forming an article from a metal or other material which increases in ductility, or has an increased capacity for deformation without fracture, when subjected to hydrostatic pressure, comprises subjecting a peripheral portion of a blank of the material to a level of hydrostatic pressure sufficient to permit the desired deformation, and forcing through a die and deep drawing at least part of the peripheral portion. Apparatus for performing the method includes a die 30 having a cavity 32 in which the blank 10 is drawn by a ram 26 operated by a cylinder 25. The die terminates in a plunger 36 received in a cylinder 46 and connected by bolts 42 to an upper fluid-driven ram 44. Surrounding the die 30 is a sleeve 28 and between the sleeve and die are passages 38 connecting a chamber 64, in which the hydrostatic pressure is applied to the peripheral portion of the blank, with an upper chamber 66 receiving the annular pressurizing cylinder 46. Valves in passages 62, 54 in the die 30 and cylinder 46 permit the cylinder to be filled with fluid 52 and fluid to escape at a controlled rate. In operation, the blank is placed, Fig. 2 (not shown), on a raised lip 20 on a block 16 in a pressure chamber 12 filled with a fluid and the die lowered into the pressure chamber by means of the piston 46. The chamber 64 is formed as a lip 34 on the end of the die and the lower lip 20 bear against opposite side of the blank, fluid passing up the passages 38 to fill the upper chamber 66. Further downward movement of the ram 44 with the sleeve 28 bearing against a stop 22 pressurizes the fluid in chambers 64, 66. Simultaneously, the ram 26 is raised to draw the blank into the die-chamber 32. The hydrostatic pressure on the periphery of the blank may be sufficient only to iron-out the periphery, or to effect extrusion with or without assistance of the ram 26. Non-circular articles may be formed, and the operations may be performed against atmospheric pressure in the cavity 32. A ring-die (33), Fig. 2a (not shown), may be used in the end of the die-cavity, against which the punch severs the end of the article if an open-ended cylinder is required. In a modified apparatus, Fig. 5, for producing an article with a stepped base, Fig. 4 (not shown), the die 30 and block 16 for use in the pressure chamber have slidable inserts 77, 80, and the lower ram 74 is stepped. The central part of the blank is formed into the inner chamber 81, Fig. 6 (not shown), by the end 75 of the ram. Continued upward movement of the ram raises the inserts 77, 80 and draws the blank into the chamber 32, Fig. 7 (not shown). In a reverse drawing embodiment, Figs. 8 and 10, a blank of larger size than the pressure chamber is first cupped into the chamber by the die 30 to occupy the position depicted in Fig. 10. The ram 26 is then raised to reversedraw the cup into the die chamber 32. As before, the pressure chambers 120, 66 are interconnected by channels 104, 108.

Patent ES-348210-A1 (ES)
Title: Detection of too many or too few characters
IPC: G06V10/98
Filed: 1967-12-13
Abstract: Apparatus for indicating errors in scanning characters in a character recognition system in which each character is expected to be scanned in a preselected number of scans, compares the total number of scans taken to complete the scanning of a word with the expected total number to derive an error count, an error being indicated if there is a predetermined difference between the error count and a reference number. In a first embodiment, a word (row of characters) is subjected to a series of vertical scans. Initially and after each character (or character portion mistakenly taken as a character, or smear satisfying a minimum character requirement) the contents of a pitch register specifying the expected number of scans per character are loaded into a scan counter which is then decremented by one each scan until it reaches zero or the end of the next character is reached, whichever occurs first. If the latter occurs first, the scan counter is then decremented by one each bit time until it reaches zero. For each pulse counted by the scan counter between character end and its reaching zero (whichever occurs first), a pulse is counted by an error counter at the same time. The error counter thus accumulates the sum (over all characters) of the signed difference between the expected and actual numbers of scans for the character. Whether the pulses are counted up or down depends on the agreement or disagreement between the sign of this "difference" and the sign of the current contents of the error counter (indicated by a sign latch) respectively, so that the error counter produces the sum stated. When a word latch is reset, an error latch is set if the contents of the error counter exceed a predetermined multiple (fraction) of the contents of the pitch register. The error latch is also set at any time the error counter reaches capacity. The word latch is set on detection of minimum character requirement, and reset on detection of a field bar (end of word), or if minimum character requirement is absent when the scan counter reaches zero (blank character) or if the recognition circuit indicates an incorrect character (smear) at the beginning of the word. The error counter takes no account of such a smear, or of the first character apparently needing too few scans as a consequence of the fact that for it the scan counter is loaded at the character beginning rather than at the end of the preceding character (in this case non-existent). A second embodiment differs in that the number of scans in the word so far is counted and the difference of this and the expected number of scans (obtained by multiplying the contents of the pitch register by a count of the number of characters including blank characters detected so far) is continually compared with a multiple of the contents of the pitch register. If the former exceeds the latter at the end of the word, the error latch is set. The error latch is also set if at any time the difference of actual and expected numbers of scans gets sufficiently large.

Title: Lubricating device for a motor compressor
IPC: F04B39/02
Filed: 1968-05-04
Abstract: In a hermetically sealed refrigerant motorcompressor unit comprising a hollow vertical shaft 16 and a lubricant pick-up tube 20 carried by the shaft and having its lower end submerged in a mixture 24 of lubricating oil and refrigerant, the tube 20 comprises an inlet 48 at its lower end and an outlet at its upper end communicating with the shaft bore 23, at least a portion of the outlet area being disposed at a greater radial distance than that of the periphery of the inlet from the axis of the shaft, the tube having a substantially cylindrical first portion 44 and a second portion 34, 40 of larger outside diameter, the diameter of the first portion being small enough to avoid cavitation of liquid in contact with its external surface, and the axial extent of the first portion being sufficiently large to isolate the liquid-whirling effect of the second portion from the inlet, whereby flow of liquid into the inlet is unimpeded by the whirling motion imparted by the tube to the liquid surrounding the exterior of the tube. The second portion comprises a cylindrical part 34 and a conical part 40. The first portion 44 is cylindrical with a bulletshaped nose 46. The tube 20 forms a centrifugal pump which pumps the mixture 24 from the sump of the unit in the form of a film of liquid which rises up the tube and the shaft bore 23 to an eccentric passage 26 having an outlet opening 28 at the upper end of the shaft. Additionally, there may be a radial port 30 leading from the upper end of the bore 23 to a helical lubricant groove 32 at the main bearing of the shaft. Gaseous refrigerant separates from the mixture within the shaft 16 above the tube 20, this action being assisted by the tendency of a partition 50 to break up refrigerant bubbles. The partition 50, which may be omitted, also acts as an impeller vane.

Patent ES-358013-A1 (ES)
Title: Continuous manufacture of reinforced hose
IPC: B29C48/32
Filed: 1968-09-10
Abstract: Reinforced elastomeric hose is produced by extruding from an extruder A an elastomeric tube, cooling the tube by means of a cooling drum 7 and a fan 8, applying reinforcement Y, e.g. yarn, applying an outer cover O of elastomeric material from an extruder B and curing the thus formed hose in a chamber H, the extruded tubing being internally supported by gas under pressure at least until the curing step has been completed. As shown, the support gas is supplied from a blower 6 and the reinforcement from lappers 10, which preferably operate successively rather than concurrently. A flash heater 11 employing hot air is situated immediately upstream of extruder B and the latter is provided with vacuum means 16 to remove any volatile matter likely to be trapped by cover O. Chamber H comprises solid particles 32, Fig. 3, e.g. glass beads 0À1-0À2 mm. in diameter, which are heated by units 33 and are agitated by, e.g. air or superheated steam, which passes through porous tiles T from a supply conduit 31. The tube may pass one or more times through the fluidized bed of particles 32. Brushes 26 remove any particles adhering to the tube and are arranged to perform a planetary motion about the tube, Fig. 4 (not shown). In modifications, circular knitting machines or braiders may be used instead of lappers 10, an accumulator may be provided immediately downstream of the reinforcing station and this station and extruder B may be duplicated to give multi-ply hose.

Title: Preparation of mercaptans and sulfides
IPC: C07C321/06
Filed: 1968-12-24
Abstract: An organic mercaptan or organic sulphide is obtained by reacting an olefinically unsaturated compound with hydrogen sulphide or with an organic mercaptan in the presence of an organic peroxide catalyst and an iron phthalocyanine, e.g. ferrous phthalocyanine or chloroferric phthalocyanine. The preferred peroxide catalysts are cumene hydroperoxide and t-butyl hydroperoxide. The olefinic compounds may be acyclic or cyclic, preferably C 5 -C 12 dicyclic olefins or C 5 -C 8 acyclic olefins. The organic mercaptans which may be used as starting materials are preferably alkyl or alicyclic mercaptans containing up to 12 carbon atoms but also include phenyl and tolyl mercaptans and mercaptobenzthiazole. The catalyst may be added dissolved in a solvent, e.g. a portion of the olefin to be reacted or an inert solvent such as benzene or cyclohexane, and the presence of water is not normally deleterious.
Patent ES-369036-A1 (ES)
Title: Gas cooling apparatus and process
IPC: C10G9/00
Filed: 1969-07-02
Abstract: A heat exchanger comprises a housing structure 31 having therein a tubular central passage 30 in which a hot fluid is cooled through the passage wall by surrounding cooling means (e.g. tubes, or as shown, a coolant jacket 40), and a hot fluid inlet tube 38 extending into the passage 30 and having its discharge end formed as a diffuser nozzle 39 with an angle of divergence of from 4 to 10 degrees. The discharge end of the passage 30 may also be formed as a diffuser nozzle e.g. 47, with an angle of divergence of from 4 to 10 degrees. The heat exchanger is intended for the rapid cooling of reaction products from a hydrocarbon cracking process the coolant being water which enters the jacket through an inlet 45 and is discharged as steam through an outlet 46. In the plant described (Fig. 1), the generated steam is collected in a drum (32) and is discharged therefrom through a line (35) for heating or power purposes. Saturated water from the drum is ducted into the chamber 40 of the heat exchanger and constitutes the coolant for the hot fluid therein. As shown, the hot fluid inlet tube 38 is secured at one end only to the housing structure so that its other end may expand freely in the passage 30. Similarly the nozzle member 47 is secured at one end only to the housing structure thus permitting expansion relative to the cooledfluid discharge member 60. This latter may be secured to the fluid outlet line 37 either directly (as shown) or through an expansion joint. A narrow annular passage 56 or 60 is formed around by the housing structure around the free ends of the inlet tube 38 and discharge tube and a steam pressure higher than that of the hot fluid in passage 30, is maintained in these narrow passages to prevent leakage through these zones of the hot fluid. This is said to reduce thermal stresses. The sealing steam is supplied to the passages 56 and 60 from chambers 41, 42 respectively.

Title: Error detector for low disparity code signals
IPC: H04L1/24
Filed: 1973-06-05
Abstract: This relates to error detection in a PCM system employing a low disparity code. A low disparity code is that type of code that over a long period of time the average number of MARKS and SPACES are approximately equal. When such a code is error free no direct current component is produced, but when an error occurs a low frequency component is introduced into the average signal value. According to the present invention errors in a low disparity code signal are detected by employing a low pass filter that will respond to the low frequency component of the average signal value.
