Patent ES-335168-A1 (ES)
Title: Speaker System.
IPC: H04R1/22
Filed: 1967-01-02
Abstract: A speaker system has two spaced, coaxially mounted cone-type low-frequency speakers of the type producing front and rear waves of acoustic energy connected such that their diaphragms move in the same direction at any given instant. An open baffle of sound opaque material is joined, acoustically tight, to each of the speakers. The speakers are enclosed in cloth. A speaker 42 (Fig. 1) has its magnet structure secured by thumb screws 43 in a socket 44 at the top of a pedestal 45. A lead shell 46 with an aperture 47 for the speaker 42 is lined with sound-absorbing material 48. A similar lead shell 49, lined with sound-absorbing material 55 and having a central aperture 56, is secured between a spider 50 and the mounting flange of a smaller speaker 51. Acoustic cloth 59 is supported by a wire frame 60 which rests on the magnet of speaker 51 and the upper edge of the shell 49. The shells 46, 49 are substantially cylindrical. Alternatively, the shells may be polygonal (Figs. 4 to 6, not shown), e.g. rectangular, and have corrugations and irregularities. The side walls may curve gently and the corners follow an exponential path. In order to supplement the upper frequency range, two smaller speakers (73, 74) are mounted coaxially in much the same way as the larger speakers except that they are not supplied with baffles. The smaller speakers (73, 74) are supported between wire frames (76, 77) above the larger speakers, and acoustic cloth (78) surrounds the frame (77). The smaller speakers (73, 74) are energized in phase with one of the larger speakers, filter or cross-over networks being incorporated where required. Alternatively, (Fig. 7, not shown), baffles (80, 81) are given a different profile so as to be accommodated in a tapering frame (82) and acoustic cloth enclosure (83). For ceiling mounting (Fig. 8), the structure of Fig. 7 is used, inverted and truncated. A frame (90) supports high frequency speakers (79) below the larger speakers. In a further arrangement, identical speakers (92, 93), Fig. 9 (not shown), with bowl-like baffles (94, 95) are joined by studs (12). The baffles (94, 95) are identical, being formed from sheet lead lined with sound-absorbing material (98). A cylindrical acoustic cloth (96) and a pedestal provide a construction similar to a table lamp. Instead of lead, the baffles may be of glass wool, felt, cork acoustic " Celotex" (Trade Mark) expanded polystyrene or foam rubber.

Title: Improvements relating to refining
IPC: C11B3/06
Filed: 1967-01-27
Abstract: The proportion of acid contaminants in commercial glyceride oils and acid amides, esters, nitriles and salts is reduced in a continuous process by treatment with an alkaline liquid, wherein reaction between said liquid and the free acid is effected almost instantaneously by intimately mixing said liquid with the oil, and water-soluble reaction products are then washed from the reaction mixture by immediately thereafter causing it and an aqueous washing liquid to make innumerable random contacts with each other while flowing along tortuous paths through a bed of inert packing material. The alkaline liquid may be 0À3 N to 1À3 N sodium hydroxide in 10 to 25% excess of the stoichiometric amount, at a temperature up to 100 C. The washing liquid may be a solution of sodium chloride or sulphate or monosodium phosphate, and may also contain ethanol, propanol, tert-butanol, glycerol or glycol or mixtures thereof. The tortuous paths may be provided by a column packed with beads, saddles or rings flow may be co-current or counter-current.

Title: Gas-liquid contact apparatus
IPC: B01J8/22
Filed: 1967-05-24
Abstract: In a gas/liquid contact apparatus liquid is circulated from a cylindrical gas/liquid separator through a U-tube with limbs 18 and 11 and back into the separator, gas being introduced into the liquid at 20, the separator 14 having a gas outlet 15 and being connected to the U-tube by pipes 13 and 16 tangentially disposed to the separator. Liquid may be introduced at 23 and the limbs of the U-tube are surrounded by heat-exchange jackets. Pipes 13 and 16 are shown horizontal but may be inclined slightly (up to 15 ), both tubes sloping downwardly from the separator. The limbs 11 and 18 of the U-tube are shown vertical but they may diverge slightly in an upwards direction. A second U-tube with a pair of tangentially connected pipes may be associated with the separator. Gas may be recirculated, liquid withdrawn and the liquid may include a solid, e.g. a catalyst, in suspension. The liquid in this latter case may be treated in a decanting vessel, a separated slurry being returned to the U-tube.
Patent ES-342088-A1 (ES)
Title: Radial Flow Fan for Pneumatic Conveying Installations
IPC: F04D29/70
Filed: 1967-06-07
Abstract: A radial-flow for pneumatic conveying installations comprises a non-rotating diaphragm 11 forming a rigid guide surface for the flow through the fan impeller 16, the diaphragm being arranged to be capable of axial deflection in a resilient manner relative to the impeller to permit a wobble movement of the diaphragm in the event of entry into the fan of a foreign body. The diaphragm 11, which comprises a conical main part 13 and outer and inner flanges 12, 14, is resiliently connected to a wall 1 by bolts 5 and springs 24 and is sealed to the wall by a flexible sealing ring 15 and a flexible bellows 23. If any of the material, e.g., textile fibres, being conveyed in the air flowing through the fan becomes trapped in the gap between the impeller blades 18 and the conical part 13 of the diaphragm, the trapped material presses the diaphragm locally away from the impeller so that the diaphragm is given a wobble motion as the material is carried round by the impeller. The local increase in the gap between the impeller and the diaphragm, which increases in the radially outward direction, permits the release of the trapped material this release being further promoted by centrifugal force. The springs 24 may be replaced by other resilient means such as rubber or synthetic plastics material. It is stated to be known to provide a non-rotating flexible membrane, as of rubber, at each side of the impeller of a pump for conveying sand, gravel or waste water, the membranes being acted upon from the outside by a pressure medium.

Title: Improvements in or relating to Apparatus for the Continuous Manufacture of Artificial Sponges.
IPC: B29C44/00
Filed: 1967-06-21
Abstract: Artificial sponge is produced in a continuous length by an extrusion feed from an orifice 16 of viscose paste, containing reinforcing fibres and sodium sulphate crystals, into a rotated annular trough defined by an electrically insulating base on a horizontal rotary table 20, and vertical metal walls 2 and 3 comprising adjacent plates connected by fluid sealing and electrically insulated expansion joints 4, which plates are connected to a transformer 5 whereby the paste therebetween is subjected to a coagulating electric current. The sponge is then lifted from the trough up a fixed wedge shaped adjustable shoe 17, and through smooth freely rotatable horizontal rollers (21) (Fig. 5, not shown), by pairs (22) of variable speed driven fluted vertical rollers alternating with pairs (23) of vertical smooth freely rotatable rollers, and with the roller path having a slight curvature opposite to that of the mould. The coagulated paste passes to rinsing and finishing baths. Fixed pressure rollers 13 bear against the upper surface of the coagulating and shrinking paste around the mould, and liquid exuded therefrom is extracted by pumps 11 or scoop elevators and part thereof is recycled to coagulating parts of the paste by sprinklers 10. Gutters 7 and 8 along the mould walls 3, 2 protect the electrical contacts from liquid overflow. Stationary rubber scrapers 24 are arranged between the shoe 17 and the extrusion orifice 16 to define a fluid tight compartment within the mould into which rinsing liquid is sprayed from heads 25 and removed by suction pipes 26. The extrusion orifice 16 faces tangentially to the mould rotation direction and the feed pipe (15) thereto (Fig. 4, not shown) from the extrusion feed screw (14) is configured through a double change of direction whereby some disorientation of the reinforcing fibres is obtained. The mould may be of curved cross-section. The supply to the transformer 5 is from an asynchronous motor connected to a three phase source, an alternator and a rotary contact. The table 20 is rotated by a variable speed motor. The electrical supply can also be effected by converting three phase current to six phase which is converted to single phase by rectifiers and an alternator. The mould may be provided with a top gas exhausting cowl. The apparatus may also comprise three concentrically arranged or superimposed moulds.

Patent ES-370691-A1 (ES)
Title: Production of worsted tops
IPC: D01G1/08
Filed: 1969-08-21
Abstract: In a process of worsted spinning the wool is subjected to the steps of washing, drying and storing in a container carding to form sliver drafting, backwashing drying gilling a second drafting combing "shuffling" and then gilling by a high-speed gill to form worsted tops. The "shuffling" is intended to correct the fibre orientation in slivers delivered from combers (in which, due to partial overlap of nipped sliver at regular intervals, irregularities in thickness occur) and thereby eliminate repeated drafting conventionally employed for such correction: shuffle is effected as a result of speed differential between top and bottom members acting on the slivers in a drafting zone. As shown in Fig. 1, fibres pass through a woolwashing machine 1 and dryer 2 to be stored in a wool bin 3 pending advancement to the hoppers of a group of carding engines 5-5n. The overlapping slivers SA delivered by the cards are passed by conveyor belt 6 to a drawing frame 7 having automatic canexchange apparatus and cans 8 for receiving drafted sliver SB which then passes through a backwasher 9, dryer 10, gill-box 11 delivering slivers SC which pass to drawing frame 12 delivering slivers SD into cans 13 supplying combers 14-14n. Combed slivers SE are shuffled by apparatus 16 to form sliver SF which is gilled by high-speed gill 17 and condensed as sliver SG for take-up as worsted top 18. The frame 7 comprises in two successive drafting zones sets of top and bottom control plate rollers in vertical and horizontal partly overlapping relation and having peripheral pointed teeth. Shuffling apparatus linking the combers and the high-speed gill comprises, in one or two drafting zones, sets of top and bottom, overlapping, toothed and sharp edged plate rollers 50 and 50', Fig. 5, or sets of top, fluted, knurled or saw-toothed rollers and bottom, plain or fluted &c., rollers 61 and 62 co-operating with an apron 65, Fig. 6, or both sets in combination, Fig. 7 (not shown).

Title: Slider holder for the assemblage of slide fasteners
IPC: A44B19/64
Filed: 1974-04-19
Abstract: An upright support structure having a slider rest on its top is slidably mounted in a hollow guide structure for up-and-down motion therethrough. A spring-actuated locking lever turnably supported inside the support structure includes a detent adapted to engage the opening in the pull tab of a slider to be placed upside down on the slider rest, and a spring-actuated stop member is also turnably supported inside the support structure to retain the locking lever in its retracted position as required. During descent of the support structure to its most depressed position withtin the guide structure, the locking lever is turned to the retracted position by a first striker disposed internally of the guide structure and is restrained there by the stop member, thereby permitting the slider to be deposited on the slider rest during succeeding ascent of the support structure back to its most elevated position. The stop member is then actuated by a second striker to permit the detent of the locking lever to engage the opening in the slider pull tab, so that the slider is locked in position on the slider rest by the time the support structure returns to its mosts elevated position for the assemblage of a fastener chain through the slider. The slider holder is further provided with means for double-locking the slider on the slider rest and with manual release associated therewith.
