Title: Process for the dyeing of polypeptide fibres
IPC: D06P1/92
Filed: 1960-09-01
Abstract: Level dyeings on polypeptide fibres, such as wool, silk or polyamide fibres, are obtained by impregnating them with a solution of a neutral to weakly acid drawing wool dyestuff at a temperature below that at which the dyestuff draws and then developing the dyeing in an aqueous bath at a temperature of at least 50 DEG C. which contains dilute acid and, dissolved or emulsified therein, at least one organic solvent which is liquid under the conditions of use, which wets the fibres, which at least partially dissolves the dyestuff and which is not completely miscible with water at room temperature. The dyestuff solution is preferably thickened with a soluble alginate salt, if desired, together with an alkyl cellulose, a cellulose glycollic acid alkali metal salt or a soluble vegetable gum, and preferably also contains an esteror amide-like condensation product of a fatty acid of 8-16 carbon atoms with an alkanolamine. Suitable p dyestuffs are specified. The acid of the development bath may be sulphuric, phosphoric, formic, lactic, chloroacetic, sulphoacetic or an alkyl- or arylsulphonic acid. Specified organic solvents are butanols, pentanols, hexanols, arylalkanols, alkoxyalkanols, aryloxyalkanols, aliphatic hydroxy acid esters, higher ketones, phenols, aromatic and aliphatic aldehydes, aldehyde hydrates, aromatic or aliphatic chlorohydrocarbons and alkyl- or alkoxy-aromatic hydrocarbons, and the preferred solvent is benzyl alcohol. The developing bath may also contain glauber salt or sodium chloride. The impregnated fibres may be dried or steamed prior to treatment in the developing bath. Alternatively, the developed dyeings may be finally steamed. Examples are given.

Title: Process of preparing a compound fertilizer containing nitrogen, calcium and phosphate, and resultant product
IPC: C05B11/06
Filed: 1961-05-27
Abstract: In a process of fertilizer manufacture, phosphate rock, especially fluorapatite, is opened up with HNO3, the mole ratio of CaO/P2O5 of the resulting solution is adjusted to be equal to or less than 2/1 either by crystallizing Ca(NO3)2. 4H2O out or by adding H3PO4, the resulting mixture is partially neutralized with NH3 to pH 1,0 to 3,0 and mineral acid is then added in an amount of 0,1 to 0,8 equivalents per mole P2O5 in the partially neutralized mixture the resulting mixture of CaHPO4, Ca(H2PO4)2, NH4H2PO4, NH4NO3 an d CaF2 may then be evaporated to a melt, granulated and subjected to after-drying treatment. The water soluble phosphate content may be increase d by decreasing the CaO/P2O5 ratio or by increasing the amount of mineral acid added after the partial neutralization with NH3. The preferred range of neutralization is to pH 1,5 to 2,5 and the preferred mineral acid is HNO3, while the neutralization with NH3 may be carried out in a continuous manner, i.e. by adding the solution of adjusted CaO/P2O5 mole ratio to a liquor which has already been treated with NH3. In the example a Kola and Kouribgha phosphate is subjected to the process of the invention to give a product containing 20,2% P2O5 10,1% of which is water soluble, and 20,0% nitrogen, 10,6% as NH3 and 9,4% as NO3 nitrogen.

Title: Delta modulation system using a constant code length less than the available code length with automatic range shift within the available code length
IPC: H03M3/04
Filed: 1965-11-16
Abstract: A train of binary-weighted pulses, each of which may have positive or negative significance, is transmitted to represent the difference between a current analogue signal sample and the immediately preceding sample. Twelve binary weights are available for coding the difference between samples, but only five are used at a time, which group of five is used depending on the previous values of the coded difference. An input sample is applied to the base of T1, which together with T2, forms a longtailed pair comparator. C1 stores a charge corresponding to the amplitude of the preceding sample. A switching network PCC is set to select a group of five pairs of positive and negative pulses PP, PN, a positive or negative pulser being selected in accordance with the output of the comparator to steer appropriate charges into Cl until it is charged to the same level as the new sample. If the coded difference is less than 01111 for a plurality of cycles, this fact being stored in a ferrite core store CM, PCC is controlled to select the next lower group of pulsers to increase the accuracy of coding. If the coded difference reaches 11101 (equivalent to 29 in range 2 -24) the next higher group of pulsers is selected by PCC. The decoder is similar in operation. Incoming pulses select positive or negative pulsers PP, PN to alter the charge on Cl, from which the output is taken through a filter. A store CM and network PCC control the steering of incoming pulses to the appropriate group of pulsers in a manner similar to that employed in the coder.

Title: Machine for casting and stacking ingots
IPC: B22D5/00
Filed: 1966-12-06
Abstract: For casting ingots 10, a machine, e.g. having wheels 510 at the rear and blocks 513 or jacks at the front for mobility has: (1) a tiltable pouring trough 237, Fig. 2, with subdivisions each ending in a spout 233 and corresponding to the number of cooling- jacketed moulds 110 or a mould group 101, 102 or 103, the moulds having ingot ejectors 111 raised by a jack 114 (2) a carriage 310 slung beneath rails 301, 302, Fig. 2, and having jaws 323, 324 opened momentarily by the rising ingot 10 of a mould group, Fig. 11, but closing again to support and convey the group of ingots when the carriage is driven by motor and gear 335 to the rear of the machine where a movable stop 341, Fig. 1, or fixed stop (345), Fig. 6 (not shown), contacts the leading ingot so that the ingots close up together (3) a table 411, Fig. 1 (with rollers or rails 415 on which the ingots can slide), raised by a jack 423 to lift the group of ingots off the jaws 323, 324 (while the carriage 310 returns to the casting zone ready to receive a further group of ingots), and lowered and turned, by a motor 414, through a right angle about a central vertical axis ready for raising to receive the further group of ingots and so on until there is formed a stack 30 of crossed layers of ingots and (4) a discharge device, which may be a jack 431 and ram 432 for pushing the ingot stack 30 on to rollers or a conveyer belt. An alternative stack-discharge arrangement, Figs. 7, 8, 15, 16 (not shown), has a plate (440) for lifting and transferring the stack 30 on to a conveyer (459). There are fins in the cooling jacket around the mould cavity 119. As shown, a mould group consists of several cavities 119 in a common outer jacket 120 with internal partitions 121 having openings for coolant flow. By pouring less metal into the cavities, as determined automatically by contact pins in the cavities, shallower ingots (20), Fig. 3 (not shown), without lifting lugs 15, 16, are produced. In order to steady the smaller ingots, there may be auxiliary jaws (321, 322), to engage beneath projections 13, 14 on the ingots which eventually lock the ingots in the stack. To determine the upper and lower positions of the stacking table 411, photo-senstive or magneto-sensitive detectors or mechanical feelers 417, 419 are used. The metal-pouring trough 237, Fig. 2, is first tilted quickly by a jack 212 pivoting its support 220 about a shaft 211 and then tilted slowly about a shaft 221 on the support 220 by a jack 222. There may be several troughs 237, one for each mould group 101, 102 and 103, or a single trough which is moved to a furnace (90) for replenishment and successively to the mould groups for pouring. The machine is operated (see Division F1) by pneumatic or hydraulic jacks and motors, Figs. 17-21 (not shown), controlled and coordinated by electric circuits, Figs. 22-29 (not shown), entirely automatically or by manual control of valves and switches. Pulses from an emitter (990), Fig. 25 (not shown), each control the extraction (from the moulds) of one group of ingots.

IPC: D01D5/08
Filed: 1967-02-07
Abstract: A cooling shaft or spinning cell for melt spinning filaments comprises a first enclosing wall located within at least one other enclosing wall, each wall extending from a spinneret or its mounting in the direction of travel of the filaments at least to the end further from the spinneret of the zone in which the filaments solidify when melt spinning is in progress, the walls being permeable to air at least in the portion surrounding the zone in which the filaments solidify when melt spinning is in progress and there being a radial clearance between adjacent walls extending from the same spinneret. The first enclosing wall may be a tube of circular cross-section and the second enclosing wall may also be of circular cross-section. The first and second tubes may be coaxial. At least one common outer wall may surround the enclosing walls extending from each of a number of spinnerets or their mountings. The radial clearance between adjacent walls extending from the same spinneret may be in the range of from 1 to 5 cm. The filaments may be extruded downwardly and the walls may be permeable above, in and below the portions surrounding the zone in which the filaments solidify when melt spinning is in progress. When filaments are extruded downwardly the upper part of the walls may have a permeability differing from that in the lower part of the walls, at least in the portion of the walls surrounding the zone in which the filaments solidify. The walls may be constructed from wire gauze, perforated sheet metal or a textile fabric. Each aperture in the wire gauze tubular screens preferably has an area of 0À1 to 2 mm.2, advantageously 0À5 to 1 mm.2.
Patent ES-340587-A1 (ES)
Title: Magnetic core assembly
IPC: H01F17/04
Filed: 1967-05-16
Abstract: Movement of ferrite adjuster slug 21 by rotation of the threaded screw 20 of adjuster 12, which at its lower end co-operates with bush or nut 23, varies the reluctance of air gap 19 between the halves 10 and 11 of a ferrite magnetic core. Bush 23 is preferably of a polyamide material which permits it, if initially unthreaded and of slightly smaller internal diameter than the over-threads diameter of screw 20, to deform when the screw 20 is inserted into it and so provide a complementary thread form. It is secured in bore 13 by an epoxy resin mass 24 and extensions of this mass 33, linking bore 13 and formed during the moulding operation which produced mass 24 and bonded it to bush 23, prevent slug 21 from contacting the wall of bore 13. Bush 23 is preferably of a non-circular outline, suitably hexagonal, so as to key with mass 24 and resist rotation.

Title: Apparatus for introducing granules in a cigarette filter
IPC: A24D3/02
Filed: 1968-02-12
Abstract: Granular particles are spread on a cellulose sheet for forming a cigarette filter by apparatus comprising a rotarydisc provided at its periphery with a succession of receptacles of equal capacity, means for continuously supplying the granules to the receptacles successively at a given angular position of the disc, means for removing the granules from the receptacles successively at another angular position, and means for directing the driven granules on to the sheet. As shown, the disc for metering the granules ' comprises a flange 21 rotated with a horizontal shaft 22, an annular member 23 separated from flange 21 by radial bars 24 and a cylinrical mesh 25 located at the base of bars 24, and annular bars 28, 29 interconnecting the bars 24. The spaces 'between the successive bars 24 constitute rectangular receptacles of equal capacity. The receptacles are filled in succession by granules.. flowing continuously from a spout 5, the filled receptacles are successively levelled by air discharged from a nozzle 30 across the rim of the disc, and air discharged from a radially-disposed nozzle 13 drives the contents of each successive filled receptacle into a duct 12 adapted to deposit the granules either on to the centre of a travelling sheet, or on to a horizontal rotary disc which distributes the granules by centrifugal action across the entire width of the sheet. In a modification the disc rotates about a vertical axis, and the receptacles are constituted by a pair of peripheral concentric walls interconnected by radial bars and a perforated bottom, the contents of the filled receptacles being discharged successively into a vertical duct by a vertically-disposed air nozzle. In a further modification the disc rotates about a vertical axis, and radial walls extend from the periphery to a concentric inner perforated wall. The periphery rotates past an arcuate concentric fixed wall which temporarily completes the outer wall of peripheral receptacles defined by the radial walls and the inner wall. The receptacles are filled and levelled while passing the outer wall, and are discharged at the outlet end of the latter into a horizontal duct by a radially-disposed air nozzle.

Patent ES-369110-A1 (ES)
Title: Fastening clip intended to be fastened with nail-driving tool
IPC: B25B31/00
Filed: 1969-06-21
Abstract: A fastening clip for fastening wires, pipes, etc. to a support comprises a plate including an opening from the edges of which two tongues of equal length extend. These tongues have a substantially S-shaped lengthwise cross section and are partly bent so as to extend with their ends over the opening in the plate thereby forming a passage for a nail to be driven into the support by a nail-driving gun. The clip, together with the nail which protrudes between the ends of the tongues, is retained in the muzzle of the gun by matching the outer outline of the tongues to the inner diameter of the muzzle. A washer is placed upon the end of the tongues for steadying the nail in the clip while the same is retained in the muzzle. The washer also serves to flatten the tongues against the support with the head of the nail pressing against the washer when the gun is fired.

Title: Improvements in and relating to tape punches
IPC: G06K1/00
Filed: 1970-02-26
Abstract: A selective tape punching apparatus comprises a platform 3 for supporting a tape and having holes 10 through which punches 13 can slide, a rotatable means 51 for sensing a code input signal and a code wheel 35 arranged to rotate synchronously with the sensing means, the code wheel being positioned relative to the punches in response to different code input signals such that movement of the platform towards an operative position causes one at least of the punches to engage a boss 36 on the code wheel thereby causing the selected punch to pierce the tape. The platform 3 is pivoted at 4 in the machine frame and is moved to its operative position by means of a solenoid 7. The code wheel 35 is made up of a series of discs (40), Fig. 6 (not shown), each having different angularly-positioned bosses 36, the wheel being rotated by means of a motor via a belt-andpulley drive 31, 32, 34. The wheel includes a boss which, at every operation, causes a related punch to pierce a feed hole which is engaged by teeth on a pin feed wheel 20 actuated intermittently by a solenoid 26. A scanning arm 37, Fig. 7, is secured to the shaft 33 of the code wheel and is arranged to co-operate with contacts (38), Fig. 5 (not shown), so that-when a signal is applied to a selected contact e.g. by a card reader, Fig. 7, the solenoid 7 is actuated and, after punching, the solenoid 26 is actuated to advance the tape. In a modification, the bosses 36 can be made removable to facilitate changing the code and the punch solenoid 7 replaced by a motor-and-clutch device.

Patent ES-386809-A1 (ES)
Title: Method and apparatus for automatic arc welding in a vertical position
IPC: B23K9/09
Filed: 1970-12-23
Abstract: A method of arc welding in a vertical direction and an arc-welding machine for automatically performing the steps of the same are provided. According to the arc welding method of the invention, the advancement of a consumable electrode wire is accelerated and the welding voltage of the welding torch is increased as the torch crosses the centerline of a generally vertically extending weaving pattern it is caused to follow during a welding operation. After passing the centerline, the voltage is decreased to its original level, as it is on the return stroke also. This method is further improved by increasing the welding current of the torch slightly after increasing the welding voltage and further by decelerating or stopping the weaving motion at both sides and at the center of the weaving path of the wire. The apparatus for automatically carrying out this arc welding method comprises, in conjunction with an advancing consumable electrode wire and a welding torch adapted to follow a weaving path in a generally vertical direction, means for changing certain of the welding conditions, such as the advancing speed of the metal wire, the welding voltage and current, the weaving speed, and means for aligning the centerline of the weaving path or width to the welding centerline of a base metal.
