Patent ES-336427-A1 (ES)
Title: Treating of fibrous materials
IPC: D01H4/08
Filed: 1967-02-04
Abstract: To reduce the number of combing-out rollers in break-spinning apparatus, one such roller is arranged to co-operate with two spinning- chambers and two feeding-devices, the drive to the latter being dependant in each case on the continuity of the yarn being spun in the corresponding spinning chamber, so that when there is a break in the yarn being withdrawn from one of the chambers, the drive to the corresponding feeding device is interrupted. A combing-roller 2 is disposed within a block I having on each side of it, a fibre-feeding device. Each device comprises la funnel 25 and a roller 19 Which feeds the sliver forward in tight formation on to the combing-roller, the two lots of separated fibres being delivered separately to oppositely-disposed channels 5. These deliver the fibres on to surfaces 7 of spinning chambers each having a collecting surface 8 air-escape apertures 10 and a fixed outlet tube 13. From this, yarn is withdrawn by rollers 14 to be taken up at 17. Between each take-up and pair of rollers is a feeler 15 which, when a break occurs, causes, through an impulse-member 22, the separation of a clutch 20 in the drive of the corresponding feed-mechanism.

Title: A current supply rail

Filed: 1968-03-09
Abstract: Conductors 4, 5, 11, 12 are supported in and insulated from a metal rail 1 by strips of plastics material 2, 21 shaped as shown. A connecting plug 13 is provided with fingers for contacting the conductors and also with fingers 18 and 19 which contact the rail to give protective grounding.

When plug 13 is to be attached to the rail the fingers are retracted by means of a knob 23 constructed such that on rotation the contact fingers 18 and 19 are projected before the other contact fingers.
Patent ES-354895-A1 (ES)
Title: Pincushion effect correcting arrangement
IPC: H04N3/233
Filed: 1968-06-11
Abstract: In an arrangement for correcting horizontal pin-cushion distortion in the raster of a television receiver the D.C. operating voltage supplied to the horizontal deflection circuit is modulated by a correction voltage waveform having a recurrence frequency equal to that of the vertical deflection circuit. The invention is described in connection with a television receiver in which the operating D.C. voltage supply V 4 (Fig. 1) for the horizontal deflection circuit 1 is derived from a voltage regulator 2 which has a first input V 1 comprising a rectified mains voltage and a second input comprising a constant reference voltage V 2 which is compared with a fraction of the output voltage, i.e. V 4 /K=V1 4 (where K is a constant) to produce an error voltage which controls the regulator such that the output voltage V 4 has a fixed value equal to KV 2 . Thus by varying the reference voltage the output voltage V 4 may be made to follow a desired law. For the correction of pin-cushion distortion the ideal correction function should have a hyperbolic form but a parabolic waveform is a sufficiently close approximation and such a waveform is derived from the S-correction capacitor normally included in the vertical deflection circuit. In carrying out the present invention (see Fig. 2) an adjustable portion of the voltage across this capacitor V1 3 =V 3 /K is derived by means of a potentiometer 7 and combined in an adder 3 with the fixed reference voltage V 2 to provide the sum voltage V 2 +V1 3 as the reference input to the regulator 2 so that the output voltage V 4 varies according to the function KV 2 +V 3 . If the parabolic voltage derived from the potentiometer in circuit 7 happens to be of negative polarity instead of positive polarity it should be added to the voltage V1 4 instead of being combined with the reference voltage V 2 (Fig. 3, not shown).

Patent ES-368883-A1 (ES)
Title: Interface unit for a telephone exchange
IPC: H04Q3/545
Filed: 1969-06-27
Abstract: Signals between an exchange network and a controlling processor are buffered in an interfacial system comprising a store for last look and command data. Each element of a buffer store in an interfacial unit corresponds to a possible test lead to the network such leads being scanned in sequence. A permanent store indicates which of the possible test leads is active in a process of comparing the test results currently present on the test leads with last-look information held in the corresponding elements of the store. Other elements of the store are used as digit registers and order registers. Any change of state detected in the last-look comparison results in a demand for the services of the processor. To connect one-and-only-one interfacial unit to the processor when a number of such units make demands for service concurrently, a two-stage switching arrangement is provided. The first stage comprises one- and-one-only selectors for respective groups of interfacial units and the second stage makes a one-and-one-only selection from among the competing demands of the first stage. To obtain access to an interfacial unit otherwise than by way of a demand originating in such unit, the processor sets the unit to a demanding state by way of a bus which resets all units before nominating one for demand. Response to such a simulated demand effects a connection to the processor over the two-stage switching arrangement. In its association with the peripheral units the processor has four modes which are, idle, receiving, transmitting and processing. The design of the interfacial units is said to be suited to large scale integrated circuit production.

Abstract: An article is formed from scrap metal by compacting the metal into a billet having a density of at least 70% of the theoretical density, heating the billet and extruding it to consolidate it to a density of substantially 100% of the theoretical density. The scrap, e.g. Ti, Zr, Mo, Nb, Ta, W, Fe in sheet, turnings &c., form is compacted at a temperature at which substantial fusion does not occur. The billet may be pierced before extrusion. The compacted billet is heated, e.g. 2000-2300 F. for steel and 1400-2000 F. for titanium, and extruded into a rod, wire, section or tube through a preheated die having a zirconia working surface. The extrusion ratio is at least 40: 1 and a lubricant of grease or a mixture of grease and glass-like material is used. A titanium or zirconium billet may be worked whilst it is enclosed in a container. The extruded rod may be cold drawn into wire.

Title: Drift corrector for transducers
IPC: G01L1/22
Filed: 1972-08-19
Abstract: Apparatus for measuring the roll separating force produced by a workpiece includes a strain gage bridge, and an amplifier having a first input connected to the output of the bridge, a second input and an output. A first circuit including a polarity reversal means and an integrator connected in series is arranged between the output and second input of the amplifier. The integrator has an input connected to the output of the amplifier, an output connected to the second input of the amplifier, and a control connection. A second circuit between the control connection and the first circuit on the input side of the integrator includes switch means operable when there is no workpiece in the mill to provide a signal to the control connection to cause the integrator to be in its operative mode and operable when there is a workpiece in the mill to provide a signal to the control connection to cause the integrator to be in its hold mode. This provides a signal to the amplifier from the integrator which is equal and opposite to the voltage from the bridge when there is no workpiece in the mill which voltage remains constant when the workpiece is in the mill. Thus, a true reading of the roll separation force is obtained regardless of the amount of drift present.
