Patent ES-314860-A1 (ES)
Title: Universal homokinetic joint
IPC: F16D3/24
Filed: 1965-07-01
Abstract: Torque transmitting balls 30 are positioned at the intersections of arcuate grooves 22, 26 and 24, 28 formed in a plate 16 secured to or integral with one shaft of constant-velocity universal-joint and in the arms 12, 14 of a fork 10 secured to or integral with the other shaft. As shown, the plate has a slot 40 extending to the groove 22 and equal in depth to the combine depths of the grooves 26, 28 in the fork to permit entry of the plate between the arms of the fork and the introduction of the balls to the grooves during assembly of the joint. Alternatively, slots may be formed in each face of the plate, or a slot may be provided in either or both internal faces of the fork arms. When the joint is assembled a pin 32 (Fig. 2, not shown) is secured to the fork and has a spherical member 34 integral or fast therewith or slidable thereon and co-operating with a socket 33 in the plate. Various modifications of the pin and of the method of securing it to the fork are described. In a modification (Figs. 14-16, not shown) a plate 126 is connected by reinforcing portions 138 to a disc-shaped portion 136 of a shaft. A lubricant retaining easing for the joint is provided by a boot 176 secured to the shaft 130 of the fork by a clamping ring 182 and secured by a clamping ring 178 to a rigid or semi-rigid sleeve 170 which is secured to the disc 136.
Patent ES-317302-A1 (ES)
Title: Shaping method including fixing the position of predetermined points in particulate mold material
IPC: B22C13/02
Filed: 1965-09-09
Abstract: In making a mould, pattern or core of intricate shape, e.g. a mould or pattern for a ship's propeller or blade, points on a required surface are established in a mass of moulding material, e.g. sand and binder in a box 13, by the insertion of a pin 11 to positions determined by a measuring device (1-10), Fig. 1 (not shown), which may be programme-controlled. A wiper is then guided by hand to remove superfluous material to expose the points and thus produce the required surface. The points are marked by balls 16 dropped into the impressions left by the pin 11 or released from the pin they may be marked by ink, by a heated pin or marker acting on a thermosetting binder or by CO 2 acting on a waterglass binder. A surface 15 may be exposed with marker balls 16 and then further material is heaped on it on a layer of separating material and the process repeated with marker balls 18 to produce a solid pattern, e.g. of a single propeller blade. A cope may be formed above the pattern in situ to form a mould, or the pattern may be removed for this purpose or used to make a mould for casting a further pattern.
Patent ES-341641-A1 (ES)
Title: Gain controlled amplifier using field effect type transistor as the active element thereof
IPC: H03F3/193
Filed: 1967-06-10
Abstract: A forward-acting gain control voltage is applied from A.G.C. amplifier 52 to the gate of a field-effect transistor 10 acting as R.F. amplifier in a radio receiver. By-passed resistors 28, 36 are connected respectively in source and drain circuits and provide connection points for the emitter and collector respectively of an NPN transistor 48, the base of which is connected to the A.G.C. amplifier 52. Below a predetermined value of A.G.C. voltage transistor 48 is cut off, due to the reverse bias derived from the voltage drop across resistor 28: for greater values, however, the transistor is conductive and clamps the source to gate voltage of field-effect transistor 10. The gain beyond this point is reduced by the shunting effect of the emitter to collector path of transistor 48 on the D.C. supply to the field-effect transistor 10.

Title: Electrical Capacitors
IPC: H01G4/32
Filed: 1969-01-17
Abstract: In a capacitor comprising electrode foils separated by strips of dielectric material wound into a roll, the foils and strips each being of substantially uniform width throughout their lengths, each electrode, over a portion of its length for several turns of the roll is arranged to project beyond the dielectric strip so as to form a contact ring for that foil projecting from an end face of the roll. As shown both foils project at the same end of the roll to form concentric contact rings 2, 3 connected to terminals 7, 9 on closure plug 10, a stud 11 of which centres the roll. Spring 12 ensures good electrical contact between rings 2, 3 and conducting members 6, 8. A third electrode may protrude from the opposite end face (Figs. 3, 6, not shown) the arrangement forming a deltaconnected capacitor (Fig. 5, not shown) or a pair in series (Fig. 8, not shown). The lead from the third contact plate may be taken through the central bore of the roll to a terminal mounted on the same closure plug (Fig. 12, not shown). Each electrode may have two contact rings one projecting from each end of the roll, and a number of such capacitors may be connected in parallel by pressing the end faces together (Figs. 9, 10, 11, not shown). The projection of the electrodes may be achieved by a gear train which shifts the axes of feed rollers sideways (Fig. 13, not shown).

Title: Water soluble silicic acid powders and their preparation
IPC: C04B35/26
Filed: 1969-06-24
Abstract: A water-soluble silicic acid powder contains at least one basic water-soluble salt of a trivalent and/or tetravalent metal, the powder being soluble in water to give a slica sol. The basic salt is a salt of Al, Ti or Zr, being present in the powder in an amount (calculated as metal oxide) of from 12-35% by weight based on the SiO 2 content. The powder may additionally contain 20-60% of a water-soluble solid hydrotropic substance which is not a salt and has a melting point of at least 30 C., e.g. urea, a substituted or cyclic urea, or a polyhydroxyl compound. A buffering mixture of acetic acid and sodium acetate may also be contained in the powder. The powder is prepared by mixing a colloidal silica sol with a solution of the basic metal salt to form a clear to opalescent solution which is then dried to give the powder. The hydrotropic substance may be added to the silica sol and the buffering mixture incorporated in the solution before drying. The solutions may be aged for 1 to 2 hours at elevated temperatures before drying.

Title: Lubrication system for change-speed epicyclic gearing
IPC: F16H57/04
Filed: 1970-02-18
Abstract: A change-speed epicyclic gearing in which lubricant is directed along two different paths according to the operative condition of the gearing.

Patent ES-432720-A1 (ES)
Title: Video amplifier circuit for use with synchronous detectors
IPC: H04N5/14
Filed: 1974-12-09
Abstract: Synchronous video detection in a television receiver provides increased detection linearity and better signal-to-noise ratio for weak signals than does envelope video detection. Impulse noise, which produces generally unobtrusive black-going noise components in a picture reproduced in response to a video signal recovered by envelope detection from a negatively modulated carrier also produces obtrusive white-going noise components in a picture reproduced in a response to a video signal recovered by synchronous detection. Common signal processing means, responsive to the envelope of the video signal modulated intermediate frequency carrier, inverts the white-going noise impulses to produce black-going components so that substantially all noise impulses appear black-going in the recovered signal.

Title: Water-soluble disazo dyestuffs containing benzylamino groups
IPC: C09B31/043
Filed: 1976-06-24
Abstract: Process for the preparation of sulphonated disazo dyes of the general formula: < IMAGE > in which X = -H, -CH3, -OCH3, -Cl, -SO3M or -NO2 Z = -H or -CH3 Y = -H or -SO3M the group SO3M is in the 6- or 7-position, K = lower alkyl having 1 to 4 carbon atoms or -CH2-CH2-SO3M if Y is hydrogen M = -H, -Na, -K or -NH4, obtained by coupling the diazonium salt of an optionally substituted aniline with a naphthylamine sulphonic acid, diazotising the compound thus obtained and finally coupling with a benzylaniline substituted in various ways. Such dyes are particularly used in the dyeing of nitrogenous fibres, where they give rise to shades varying from red to violet, with very good general fastness properties, affinity and levelness. They have the fundamental and determining advantage of not involving the use of alpha -naphthylamine in their preparation, unlike other dyes of similar structure which require particular care and precautions due to their noxious toxicological properties.
