Patent ES-335503-A1 (ES)
Title: Facsimile synchronizing system
IPC: H04N1/36
Filed: 1967-01-11
Abstract: In facsimile or other equipment in which transmitting and receiving transducer yokes are driven by synchronous electric motors via intermediate " actuators," synchronizing pulses from the transmitter operate the receiving actuator so that its yoke is locked to the drive only when the drums are in phase synchronism. Prior to this the yoke is driven at some 90% normal speed via epicyclic gears and a centrifugal friction clutch 98. The synchronizing pulses are transmitted during an initial period only, determined by thermal switches at transmitter and receiver, and comprise a continuous black level signal interrupted when a magnet carried by the drum closes a stationary earthing switch at the datum position. Transmission is by frequency modulation of an audio oscillator by optical scanning means, the oscillator being coupled to a standard telephone handset. The intermediate actuator comprises an arm 112 carrying two coupled pawls 114, 116. 114 can engage any tooth in a wheel 120 (driven directly at synchronous speed) and 116 engages a detent 128 in a member 24 coupled to the yoke. Initially, the pawl 114 is engaged and the actuator arm 112 is carried round until the pawls reach a datum position defined by the armature of an electromagnet (not shown). While the magnet is energized the pawls are disengaged and the arm 112 held, but on arrival of a synchronizing pulse the magnet is released and the pawl 114 again engages the wheel 120, but this time in phase synchronism with the transmitter. When the second pawl 116 meets the detent 128 the drive is transmitted to the yoke. Since the speed of the centrifugal clutch 98 depends on the difference between the speed of the yoke and synchronous speed, this now disengages and synchronism is complete. The actuator is arrested whenever it reaches the electromagnetic stop unless this occurs in synchronism with the de-energizing pulse. When the thermal switch has timed out the magnet is permanently de-energized and the facsimile transmission commences.

Title: Process for the removal of hydrogen sulphide from carbon dioxide and gas mixtures containing carbon dioxide
IPC: C01B32/50
Filed: 1967-02-16
Abstract: Hydrogen sulphide is removed from carbon dioxide, or a gas mixture containing carbon dioxide, by scrubbing the gas with an aqueous solution of hydrogen peroxide. Preferably the concentration of hydrogen peroxide is 1 to 30% by weight (3 to 8% being particularly preferred) and alkali, e.g. sodium carbonate or bicarbonate, is added to the starting solution in approximately 10% excess of the quantity required to neutralize the sulphuric acid formed by the process. The scrubbing temperature lies preferably between ambient temperature and the freezing point of the solution, but may be higher. Scrubbing pressure may be atmospheric or superatmospheric.
Patent ES-337737-A1 (ES)
Title: Method of improving the purity and homogeneity of threads or filaments in melt-spinning
IPC: D01D5/08
Filed: 1967-03-08
Abstract: Molten polymer is mixed prior to melt spinning by passing the polymer through one or more mixing elements 8, contained in parallel bores 7 situated immediately above the spinneret plate 4 which supports the filter assembly 10, the component stream of polymer in each of the mixing elements being repeatedly divided several times into two to eight filamentary flows which are recombined after each division. Each mixing element may have from 2 to 10 flow dividing devices 12 and the mixing elements communicate at their upper end with a distributing chamber 3 situated beneath the filter assembly and with a storage chamber 9 at their lower end situated just before the spinneret, the storage chamber being of very small volume so that the mixing occurs immediately prior to the spinning in such a manner that the component streams do not merge before spinning. When spinning monofilar and multifilar textile threads or filaments with a low count one mixing device may be used which is advantageously fitted into the supporting plate transversely to the direction of flow of the melt. The same arrangement is possible if 2 or 3 mixing elements are used.

Patent ES-339192-A1 (ES)
Title: Improvements in or relating to Fluid Braking Systems
IPC: B60T11/34
Filed: 1967-04-12
Abstract: In an hydraulic brake force regulator, a cylinder 1 having a fluid inlet 8 and an outlet 9 to the brake cylinders, contains a stepped piston 29 which has a conical portion 28 arranged to engage, and to form a seal with, a sealing ring 12 when pressure difference between inlet 8 and outlet 9 falls sufficiently, the piston having a small diameter end 13a, 13b bearing against a spring 6 adjustable in pressure at 7, and having a passage 19 therethrough containing a non- return ball valve comprising a ball 21 and seating 22. Increase in applied pressure at the inlet 8 is transmitted via the annular gap between the conical section 28 and the sealing ring 12, to the outlet 9. As the outlet pressure in chamber 27 rises, its action on the larger diameter end of the piston overcomes the spring 6 and moves the piston to the right to decrease the annular gap, and eventually to close it. Upon reduction of the inlet pressure 8 the piston moves further to the right and return of fluid from the brake cylinders must then occur through the ball valve 21 which acts as a throttle to limit the speed of flow.

Abstract: A device for tensioning a number of strips to be wound about a common mandrel comprises a separate tensioning roller having a plurality of freely-rotating crowns which can be braked by an axially exerted force, and a casing partially housing the roller into which air or compressed gas is introduced to force the strips into contact with the crowns. Fig. 1 illustrates a general arrangement in which strips are led round a barrel 1 fixed to arbour 3 the strips are pressed into contact with freely rotating crowns 4 by means of air or compressed gas introduced through inlets 16 into casing 15, an effective seal 17 between the casing and the strips being provided. Fig. 3 illustrates the braking system which ensures a constant braking action on strips, e.g. 20, 21, led around the roller. The crowns 4 are separated from each other by thin friction discs 5 which engage at 6 with longitudinal grooves 7 in the barrel 1 the discs therefore rotate with the barrel, and both the discs and the crowns are axially slidable. The barrel carries a fixed annular abutment (8) at one end (Fig. 2, not shown), and a further fixed abutment 9 at the other end an annular interposed piece 13 is movable under the controlled action of inflatable toric tube 11 to force the crowns 4 against the discs 5, thus braking the rotation of the crowns and applying a uniform tension to the strips. The barrel 1 and arbour 3 can, if desired, be given a controlled rotation.

The central tubes are vertically reciprocable by means of jack 73 acting through rocker arm 74 on to head 52, biased upwards by spring 53. The nozzle 16 is reciprocated vertically also as a whole by jack 71 acting through crank 72 and rollers 62 against ridges 46, 47 and is reciprocated horizontally by jack 64 acting through its rod 65 and arm 66 connected to supports 63, 67 and forming a parallelogram arrangement with arm 68. A sterile air dryer 69 may be used to dry the nozzle. The swinging of the extruder is regulated by cam (32, Fig. 4, not shown), rotated by drive (31) from motor (28), a further drive (30) from which regulates the turntable rotation. Operation.-During the rearward swing of the extruder, grippers 23 open, move up and are then closed on the extruded parison and lowered during the forward swing of the extruder while being partially pre-blown through the die and initial mould closure. A further blowing after complete mould closure forms a flange, nipped off at the top of the mould and the parison is severed, the extruder then swinging back for similar subsequent operations. The closed mould continues to rotate, the neck being held by the grippers, to engage nozzle 16 which effects the blowing proper and filling. The bottle is then sealed at the neck (Figs. 8, 9, not shown) before trimming and mould opening.

Title: Process for producing carbon fibers from mesophase pitch
IPC: D01F9/32
Filed: 1974-12-10
Abstract: An improved process for producing carbon fibers from pitch which has been transformed, in part, to a liquid crystal or so-called "mesophase" state. According to the process, carbon fibers are produced from pitch wherein the mesophase content of the pitch has been formed while agitating the pitch so as to produce a homogeneous emulsion of the immiscible mesophase and non-mesophase portions of the pitch. Mesophase pitches prepared in this manner have been found to possess a lesser amount of high molecular weight molecules in the mesophase portion of the pitch and a lesser amount of low molecular weight molecules in the non-mesophase portion of the pitch, and thus a smaller differential between the average molecular weights of the mesophase and non-mesophase portions of the pitch, than mesophase pitches having the same mesophase content which have been prepared in the absence of such agitation.
