Title: Signalling arrangement for telephone instruments
IPC: H04M1/02
Filed: 1959-10-26
Abstract: In a standing microtelephone set (Fig. 1) having a receiver 8 in the upper part of the handle and a microphone 9 in the foot, a sound producer 1 responsive to audio-frequency currents is provided in the handle or the upper part of the foot and communicates with a funnel 2, or a resonator (Fig. 2, not shown), in the handle communicating with the sound producer 1. The sound producer 1, which may be a small loud-speaker, is acoustically matched to the funnel 2 or the resonator, and may be actuated by an audio-frequency current (for example of 2000 c.p.s.) transmitted from an exchange, the sound producer 1 being connected in series with a condenser across the line wires in the manner usual for a bell. In a modification ringing current (e.g. of 25 c.p.s.) from an exchange modulates the oscillations produced by a transistor oscillator in the telephone set and the modulated output is fed to the sound producer 1. As shown in Fig. 3, the speech circuit is a conventional one with impulse springs 16, 17 and dial off-normal contacts 18, 19, which is connected to the line wires a 1 , b 1 by operation of the hook-switch contacts 11 to 15 when the telephone is lifted up. In the rest condition these contacts connect up the signalling circuit shown on the left of the line A-B. Condenser C1 is charged by the positive half-cycles of the ringing current and is short-circuited by rectifier L during the negative half-cycles. Directcurrent pulses are thus delivered from C1 to the transistor TR so that current flows in the collector circuit and through the sound producer S, positive feedback being provided by the transformer N. The output applied to S consists of a carrier and two sidebands and two series-connected resonators are provided in the handle of the telephone set (instead of the funnel 2) which resonators are tuned to the respective sideband frequencies. The input impedance of the lower of the two resonators is matched to the output impedance of the sound producer.

Title: Improvements in and relating to hair-dressing devices and the treatment of human hair
IPC: A45D6/06
Filed: 1962-06-28
Abstract: Hair is curled or straightened by holding a tress of hair in desired configuration between the walls of a former by a flow of air passing between the walls and applying heat to the hair while it is in the desired configuration, to dry it. As shown a former, made by winding a sheet of non- corrosive material into a spiral, has enclosed ends 12, 14, and a tress of hair, sucked into the spiral through the mouth 18 by a suction pump connected by a pipe 20 to the centre of the spiral, is dried by heated air passed between the pipe 20 and casing 26 to enter the outermost spiral of the conduit through an annular aperture 28. The tress of hair is gripped by a spring- urged clamp which is positioned near the mouth 18 and is operated by a lever on the outside of the casing. Suction may continue during the passage of heated air through the conduit and, before or after the hair is dried, a treating liquid may be introduced through the aperture 28. An adaptor for use when only the ends of a tress is to be curled has superposed straight conduits for hair and for drying air and is interposed between he former and the scalp by engagement with the lips 34. Apertures in the adaptor allow the passage of hot air towards the scalp to dry the roots of the hair. In modifications the hair receiving conduit is straight, to straighten a tress of hair, or is corrugated.
Patent ES-290327-A1 (ES)
Title: Process for preparing a formaldehyde solution containing a stabilizer
IPC: C07C47/058
Filed: 1963-07-26
Abstract: A stabilized aqueous solution of formaldehyde containing 15-60% by weight of water is prepared by introducing cyanuric acid during the formation of the solution in such an amount that the prepared solution contains 3-8 moles of formaldehyde per mole of cyanuric acid. An aqueous solution of formaldehyde which is dilute enough to be stable may be first prepared, cyanuric acid then added and water evaporated until the solution contains 15-60% of water. Alternatively the stable solution may be continuously prepared by supplying formaldehyde-containing gas to an absorption system comprising two or more stages in the first stage the gas is washed with an aqueous solution of formaldehyde and cyanuric acid and in the last stage gas not absorbed in the preceding stage(s) is washed in counter-current with water, the solution resulting from the absorption in the stage(s) after the first is used in conjunction with part of the solution produced in the preceding stage as washing liquid in that stage and the part of the solution produced in the first stage which is not recirculated is discharged from the system as final solution.

Title: Ultrasonic apparatus for measuring the position of a liquid level
IPC: G21C17/035
Filed: 1966-12-15
Abstract: In an ultrasonic liquidlevel gauge, ultrasonic waves are conducted through a guide vowprising a tube filledhithan auxiliary liquid moaing acoustic properties similar to those of the liquid whose level is to be gauged. For measuring the level 17 of liquid sodium or sodium - po - tassium coolant 51 in a nuclear reactor vessel the tube 1, containing a eutectic sodiumpotassium mixture, is adjustably mounted in the vessel wall by means of flanges 15, 16, screws 19 and metal bellows 18. The tube 1 is sealed by acoustically transparent end-plates 3, 4, and is surrounded by perforated tube 28 which dampens movements of the coolant surface 17 and also supports a conical reflector 22. Ultrasonic pulses generated by a quartz transducer 6 (adjustably mounted in a kerosene-filled casing 5) pass through the waveguide, are reflected from reflector 22, and pass between tubes 1 and 28 to the coolant surface 17 from which they are reflected back via the same path to the or a further transducer. The echo-time of a pulse provides a measure of the coolant level. Lugs 31 at known positions in tube 28 provide reference echoes for calibration purposes. In alternative embodiments the gauge is mounted in or near the bottom of the reactor vessel (Figs. 3 and 4, not shown), whereby the ultrasonic pulses can be directed through the waveguide to the coolant surface without the need for the conical reflector 22, or is mounted in the vessel side wall (Fig. 5, not shown) with the waveguide horizontal, a plane reflector being used to direct the pulses upwards to the coolant surface.

Title: Filter element
IPC: B01D29/00
Filed: 1967-04-27
Abstract: An inward-flow filter element comprises a cloth bag 54 stretched over a perforate tubular support 20 and a movable end disc 32, which is moved away from support 20, against the compression of spring 42, to stretch and/or shake the bag, by reverse flow cleaning fluid from pump 12. The fluid is pulsed by a rotary valve 18 if the cloth is elastic or by a vibrating valve, at higher frequency, for inelastic cloth. In Fig. 1, support 20 is a metal tube and disc 32 is fast with a hollow piston 36 slidable on a cylinder 38 which is fixed to conduit 28. A valve 48 comprises a movable member 52 with a small central, orifice, which lifts to allow filtrate to flow through hollow stem 44 and conduit 28 to outlet 14 but falls to build up sufficient pressure difference in reverse-flow fluid passing through the orifice to extend piston 36 repeatedly. Tube 22 forms an empty space with conduit 28 to reduce the internal volume. In Fig. 2 (not shown) the bag is supported by perforate polypropylene washers (64), and end disc (321) is moved by inflation of a flexible tube (76), in parallel with a valve (481) similar to valve (48). A filtrate pump is located downstream of valve 14. In either embodiment, valve 14 could communicate with the downstream side of support 20 directly.

Title: Apparatus for Coating Surfaces with Thermoplastic Materials.
IPC: E01C23/20
Filed: 1967-05-06
Abstract: In a mobile apparatus for coating a surface with a thermoplastics material, e.g. for producing line-markings on roads or for coating the surface of a floor, the coating material is contained in its solid state in an unheated supply means 8, the lower portion of the solid material in means 8 being in direct contact with a heated intermediate rotating roller 2 such that a molten film of material formed on the roller 2 is transferred to a smaller applicator roller 3. The supply means may comprise a ring in which a rod of the solid thermoplastics material can be placed. The intermediate roller is driven by a belt 5 and a pulley 4 which is fast with wheels 7 provided for movement of the apparatus. Temperature control of the roller 2 is effected by regulating the delivery of gas from container 9 to burner 6 and regulating the speed of rotation of the roller 2. A spring 10 biases the applicator roller 3 against the surface to be coated. The cross section of the roller 3 may vary along its length.

Title: Apparatus for the hydrostatic transmission of mechanical torque
IPC: F04B1/12
Filed: 1967-05-20
Abstract: In a hydrostatic transmission for a vehicle wherein a variable displacement swash-plate pump 2 having a rotary cylinder block 4 supplies pressure liquid to two or more motors 36, 37, a driving gear 15 fast with the cylinder block 4 is driven from an input shaft (1) through a reduction gear (12), 15. The gear 15 may be integral with the cylinder block 4. The input shaft (1) may, Fig. 1 (not shown), be parallel to the pump axis and drive the cylinder block through straight or helically toothed gears (12), 15, or the input shaft may be perpendicular to the pump axis and drive the cylinder block through bevel gears. The rotary cylinder block 4 of the pump bears against the spherical surface of a fixed distributer plate 21 and carries pistons 6 which bear on the spherical surface of a non-rotary swash-plate 7. The inclination of the swashplate 7 is varied by supplying pressure fluid to a servo 61. A spring 32 acts through a sleeve 20 to bias the cylinder block 4 into engagement with the distributer plate 21. During normal running the spring pressure 32 is augmented by supplying pump output pressure to the interior of the sleeve 20 and during overrun the return pressure augments the spring pressure. The motors 36, 37 have radial pistons 40, 41 carried by output cylinder blocks 36, 37 and engaging eccentric rings 42, 43 freely rotatably mounted in housings 48, 49 which are pivoted about an axis 53 to vary the eccentricity of the rings 42, 43 and thus the displacement of the motors. Alternate pistons 40 (or 41) of each motor are oppositely inclined to a radial plane. Pressure fluid is supplied to the motors 36, 37 through a common distributer 28.
Patent ES-342284-A1 (ES)
Title: Power transmission device with variable progressive speed
IPC: F16H15/38
Filed: 1967-06-24
Abstract: A variable speed gear comprises a hydrodynamic torque converter 101 having its output member connected to the input shaft 105 of a mechanical continuously variable speed gear 102, the ranges of reduction ratio D c , D v of the torque converter and mechanical gear respectively being such that the values of ratio D v /D c at the extremes of the range of overall ratio lie between 0.6 and 1.5. As shown, a separating clutch 123 is included between the torque converter output and the input of the mechanical gear 102. For forward drive, a double clutch 124 connects the input shaft 105 to a shaft 106 driving a primary shaft 108 via gears 107. The gear 102 includes two similar interpenetrating disc stages in series. Shaft 108 carries friction discs 109 interleaved between rings 110 splined to a casing 111 which in turn is splined to a shaft 112 carrying friction discs 109 interleaved with a second set of rings 110 splined in a ring 113 which is splined to an output shaft 118. Casing 111 and shaft 112 are rotatably mounted in an arm 122 pivoted at 117 to the gear housing. To vary the ratio of gear 102 the arm 122 is pivoted in one or other direction by opposed fluid actuated rams 116. For reverse, a pinion is clutched to shaft 105 by clutch 124 to drive the output shaft 118 directly through meshed gears (119), (Fig. 4, not shown), the friction gearing being bypassed. In Fig. 2 (not shown), a torque converter (1) drives a toric disc type of continuously variable speed gear (2), the inclination of two sets of idler rollers (11, 12) being adjustable in unison to vary the gear ratio.
Patent ES-346430-A1 (ES)
Title: Belt tracking device
IPC: G03G15/00
Filed: 1967-10-25
Abstract: In a xerographic copying machine a belt 2, e. g. of brass carrying a photo-conductive layer passes around rollers 4, 6, and 8 through charging, exposure, development and transfer stations. The belt is maintained in correct transverse alignment under the control of an edge feeler 70, Fig. 7, which upon deviation of the belt to the right, rocks a lever 72 which in turn displaces a rod 80. The rod 80 rocks an arm 82 which through a screw 88 rotates a frame (40, Fig. 1, not shown) clockwise against the action of a spring 92. The rotation of the frame (40) tilts the axes of the rollers 4, 6 and 8, such that the belt moves away from the feeler.
Patent ES-348759-A1 (ES)
Title: Improvements in or relating to Disc Brakes
IPC: F16D55/14
Filed: 1967-12-29
Abstract: In a disc brake of the kind in which two co-operating thrust plates 7, 8 are accommodated within a stationary housing 2 and are located between brake discs 3, 4, which are connected to a shaft 1 to be decelerated, the thrust plates 7 and 8 are separated by means of a toggle linkage 21, 22, 23 and balls 11, located in conical recesses 9, 10 in the adjacent faces of the thrust plates, effect frictional engagement of the latter with brake linings of 5 and 6 on the brake discs. A plurality of centering cams 15, 16 are provided on the circumference of each thrustplate and corresponding projections 12, 13, 14 are provided on the housing 2 such that each projection has a stop surface of 1411 for restricting rotational movement of the thrust plate and a guide surface 141 for engaging centering cams to effect a centering action on the thrust-plates. The arrangement is such that when the brake is operated and one thrust-plate is engaged by a stop surface which is substantially radial to the thrust plates, the centering cams on the thrust plate which is not engaged by the stop surface are brought to rest in positions where the centering cams cannot, engage the guide surfaces of the housing projections. The housing projections may be rounded or cut back at both ends 25 of their guide surfaces 141 as shown-in Fig. 5. The above arrangement is stated to avoid frictional losses caused by a double centering action.

In one example the plastics material is a polyester, a first filler is of granular form, for example sand, quartz sand, slag grains, brick powder or expanded fired clay and a second filler is fibrous, for example glass fibres. The filler is fed into the mould by a pipe moved axially back and forward in the mould, the speed of movement of the stroke or the time rate of application being varied.
Patent ES-357096-A1 (ES)
Title: Method of manufacturing impregnated fibre material in sheet form
IPC: B29C70/50
Filed: 1968-08-09
Abstract: In the manufacture of a laminate, a fibrereinforced sheet is made by uniformly distributing fibres over a surface, forming spaced bodies of a flowable bonding material on the fibres, the spacing being sufficient to ensure that the bonding material in each body flows individually downwardly through the fibre layer and that the bodies are united by lateral flow at the bottom of the fibre layer, then causing the bonding material to flow through the fibres between the bodies to complete the impregnation of the fibre layer. As shown in Fig. 2, continuous strands or short fibres of glass or asbestos pass along tube 41, and are cut into short fibres by a cutter 46, which is oscillated transversely of advancing film 15, and deposited on to film 15. The deposited fibre layer is made uniform by vibrating plates 68, 69 and made of constant width by transversely oscillating ploughs 71, 72. The resin flows on to the fibre layer in separate streams from hopper 19. This hopper comprises a sloping end wall and an attached castellated plate (84) to separate the overflowing resin into separate streams. The hopper has an internal castellated baffle (85), see Fig. 6 (not shown). The hopper also comprises individual resin stream adjusters to maintain uniformity in the separate resin streams. The resin can contain polyester, calcium carbonate, magnesia, pigment and t-butylperbenzoate. The impregnated web can have a second amount of fibre strewn on its upper surface. A covering sheet is then applied to the fibre layer which is then covered with a sheet and pressed between rollers so the resin uniformly impregnates the fibres. The impregnated fibre sheet is then either wound up or passed through a curing oven and cut into separate, optionally corrugated or curved, sheets. The film 15 and the covering sheet may be of polyethylene or cellulose acetate.
