Title: UN MONTAJE PARA CONVERTIR UNA TENSIoN DE FORMA DETERMINADA EN OTRA TENSIoN DE OTRA FORMA
Filed: 1947-12-26
Abstract: Montaje para convertir una tensión que afecta una forma determinada en una tensión de otra forma y, eventualmente, de otra frecuencia, caracterizado porque la tensión a convertir es aplicada a dos circuitos de carga con condensador común cuyos circuitos transmiten corrientes de sentido inverso y tienen elementos no lineales mandados con ayuda de una tensión pulsatoria, constituída por impulsos, cortos con relación a su separación, de tal manera que según el sentido de variación de la tensión a convertir, uno u otro circuito de carga esté en funcionamiento durante la duración del impulso, pudiendo presentar además este montaje las particularidades siguientes tomadas por separado o en combinación: a) el condensador está shuntado por una resistencia y la constante de tiempo del montaje en paralelo se elige de modo que, durante cada duración de impulso, el condensador se cargue o se descargue hasta el valor instantáneo de la amplitud de la tensión a convertir durante este impulso, al paso que, durante el intervalo comprendido entre los impulsos, la tensión del condensador permanece prácticamente inalterada; b) los dos circuitos de carga tiene una impedancia de entrada común ala cual se aplica la tensión a convertir y los elementos no lineales están constituídos por las impedancias ánodo-cátodo de dos tubos de descarga conectados de modo que el cátodo de uno de los tubos está unido con el ánodo del otro y viceversa; c) cada uno de los tubos de descarga tiene una rejilla de mando y a estas rejillas se aplica simultáneamente un impulso de tensión positiva con relación al cátodo correspondiente; d) la frecuencia de los impulsos que mandan los elementos no lineales de los circuitos de carga es tan elevada con relación a las componentes de frecuencia a transmitir de la tensión a convertir, que se toma del condensador una tensión cuya forma varía de una manera discontínua con la frecuencia de los impulsos y se acerca a la de la tensión a convertir; e) la frecuencia de los impulsos es igual a, o constituye un sub-armónico de la frecuencia de la tensión a convertir y del condensador se toma una tensión contínua cuya magnitud y amplitud dependen del intervalo de tiempo comprendido entre la manifestación de un impulso y el paso por cero contiguo de la tensión a convertir.

Title: Improvements in or relating to chain conveyors
IPC: B65G17/38
Filed: 1963-07-24
Abstract: In a chain conveyer of the kind in which alternate links 31, 32 carry respectively support rollers and guide rollers 8, the links each consist of a pair of parallel arms joined at their ends, there are two rollers to each link, the plane of each roller is perpendicular to the plane containing the longitudinal axes of the link arms, the rollers are mounted midway of their respective links and the links provided with the support rollers carry load-bearing or loadengaging members which are preferably suspended from the roller axles. The chain runs in a guideway with a slot from which the load-bearing or engaging member projects: Fig. 1 of the Complete Specification, and Figs. 2 and 4 of cognate Provisional Specification 27519/63 (not shown) depict crosssectional views of suitable guideways. The chain is driven by a six-toothed sprocket whose teeth 156 engage the appropriately bushed guide roller axles. To make this possible the guideway has to be cut away at the drive point and to prevent the support rollers falling through the cut-away portion the sprocket is provided with platforms 157 which temporarily support the support rollers. The load-engaging means carried by the support roller axles may be dogs for pushing trolleys along a track. Such trolleys (Fig. 1 of cognate Provisional Specification 27519/63, not shown) have pivoted pawls (50) which are counterweighted (at 48) arranged in facing pairs between which the dogs (33) can engage.

IPC: H02K31/04
Filed: 1966-11-25
Abstract: In a homopolar generator which is used for the generation of high-energy D.C. pulses of short duration, the voltage of this pulse is increased by a transformer employing part of the stator core as its magnetic circuit. Working flux generated by field coils 6, 7, passes along the paths shown from rotor 3 to circumferentially laminated stator core 11, through radial flanges 27, 28, 29, 30. The rotor is faced with conducting material 5, e.g. copper, which is connected by liquid brushes 8, 9, e.g. using mercury, to a toroidal single-turn, strip-wound primary winding 16 round the stator core 11. This winding may be closed, when it is desired to produce a pulse, by an electromagnetic switch 23-26. The secondary winding 12 consists of several strip-wound turns connected to outlet terminals 14. The core 11 is polarized by a fine wire winding, not shown. In operation, the machine is run up to speed and the brushes 8, 9 are filled with mercury simultaneously with the closing of switch 23-26.

IPC: A01K31/04
Filed: 1968-11-21
Abstract: Cleaning apparatus for removing droppings from a battery system comprises a scraper 17 arranged to travel in stages along a collecting tray 12-14 below cages 11, returning after each stage to a discharge end 19 to remove droppings accumulated on the portion of the tray last traversed, the scraper 17 travelling forwards and backwards until the whole of the tray has been cleared. In a three tier battery, Fig. 2, each scraper 17 is carried by a chassis 37, Fig. 3, slidable on channel section members 15 of a main frame 10, and discharges the droppings onto a conveyer 21. A respective draw bar 41 is slidably mounted on the chassis 37 and is secured at each end to a common driven cable 18. The scraper 17 is pivoted on a pin 44 attached to the bar 41 and is further pivoted to links 45 pivoted to the chassis 37. On actuating the cable 18 away from the discharge end 19, the scraper 17 is pivoted to an essentially horizontal position, whereupon the chassis 37 is pulled outwardly, and on reversing the cable 18 the blade 17 resumes its operative position, the links 45 engage stops 46, and the scraping operation is performed. The common cable 18 is operated by a reversible electric motor 35, controlled automatically after initiation of the process by a sequence controller (47), Fig. 1 (not shown), and an electronic timing device (48), incorporating a distance control (49) for pre-setting the length of each scraping stage. Alternatively a portable power unit may operate the cleaning apparatus of several battery systems in turn, and the scraper drive may be utilised to operate a feed dispensing system.

Patent ES-401509-A1 (ES)
Title: Production of fibers from thermoplastic materials, particularly glass fibers
IPC: C03B37/04
Filed: 1972-04-06
Abstract: The production of fibers from thermoplastic materials, particularly glass fibers, by feeding a molten stream of the material into the interior of a hollow centrifuge body of enlarged diameter rotating rapidly around a vertical axis, which body is provided with a peripheral wall of substantial height which is pierced with a large number of rows of orifices through which the molten material is projected by centrifugal force in the form of filaments, which are then attenuated into fibrous form by hot gaseous blasts acting in a direction transverse to the planes of emission of the filaments. The deformation of the centrifuge body is reduced and its operating life is extended by critically controlling the temperature of the molten material which is projected through the orifices by first directing the incoming stream of molten material onto an annular supporting element or flange which is integral with the lower edge of said peripheral wall and extending inwardly therefrom, wherefrom the molten material is distributed in an upward direction along the interior face of said peripheral wall in position to be projected through the orifices therein. The introduction of the molten material upwardly from the annular flange or support element enables the accurate control of the temperature of the molten material by heating the latter or the support element so that the temperature of the peripheral wall is substantially constant along the entire height thereof, resulting in the production of fibers of uniform characteristics.
