Title: Procedimiento de peletización con caliza para minerales finos y de alta humedad de peletización
Inventor: NACER AWAD ORLANDO
IPC: C22B1/00
Filed: 1975-12-24
Abstract: Esta solicitud se refiere a un procedimiento de obtención de pelets, utilizando caliza como agente aglutinante, para minerales finos que requieren una alta humedad óptica de peletización. Se considera específicamente para residuos ferríferos de las plantas de níquel que procesan minerales laterítico, donde la fineza del mineral y alta prioridad en las partículas individuales provoca una alta humedad optima de peletización la adición en determinada proporción de caliza, preferiblemente con baja humedad molecular máxima, así como posterior homogeneización facilitan tanto la manipulación como la peletización de la mezcla. Por este medio se disminuye sensiblemente la humedad óptima de peletización, con el consiguiente ahorro energético en el secado, y los pelets obtenidos tienen buenas propiedades físicas (más resistentes y porosos)

Title: Improvements relating to methods of encapsulating electrical components in solventless synthetic resin
Inventor: REECE CHARLES NORMAN WILLIAM
IPC: H01B3/30
Filed: 1960-01-05
Abstract: An electrical component such as a transformer is encapsulated by placing the transformer in a moulding vessel located in a chamber connected by valves to a vacuum pump, a supply of sulphur hexafluoride, and a supply of uncured solventless synthetic resin. The chamber is evacuated and the transformer heated to remove moisture &c.  Sulphur hexafluoride is then admitted until the pressure rises to atmospheric and the gas permeates the parts of the transformer.  The chamber is then evacuated again and the moulding vessel filled with resin while the vacuum is maintained. Sulphur hexafluoride is then admitted until the pressure rises to thirty pounds per square inch to assist the penetration of the resin into the interstices of the transformer, and the resin is then cured while said pressure is maintained.  any cavities in the resin are filled with sulphur hexafluoride which has a greater dilectric strength than air and is therefore more difficult to ionize.  The steps of evacuating the chamber and filling it with sulphur dioxide may be repeated several times.  The moulding vessel may form a permanent casing for the transformer.

Title: Improvements in and relating to methods of manufacturing road surfaces
Filed: 1933-01-05
Abstract: A road surface is formed with at least one layer consisting of a coarse fibrous vegetable material woven or interlaced to form a mat and impregnated with a vegetable oil, fat, or resin, or with latex or latex derivatives, or with a mixture of such substances and/or a combination of such substances with bituminous substances.  The coarse fibrous material is obtained from the leaves, stems or roots of water or bog plants, fibrous basts, varieties of straw and bamboo, pressed sugar cane and the like, and are of sufficient length, in their original or impregnated state, to be woven or interlaced.  The bituminous materials, for example, asphalt, petroleum, tars, pitches from coal, brown coal, lignite, and oil shale, are combined either separately or in a mixture with the vegetable oils or the like, and the fibrous vegetable materials are impregnated with this mixture either before or after they are woven or interlaced to form the mat. The impregnated mat may be embedded in a binding medium which may be the same as or similar to the impregnating agent employed, and in such cases an organic or inorganic filling material such as asbestos, powdered stone, chopped straw, chaff, wood meal, and the like may be employed.  The bituminous and vegetable impregnating substances may be mixed under heat in the presence of sulphuric acid or substances having a similar action to sulphuric acid when heated.  In such cases, the vegetable impregnating agents preferably used are rape oil, soya bean oil, castor oil, Chinese wood oil, or vegetable resins such as colophonium, pine resin and shellac or with rubber, guttapercha and the like.

Title: Improvements in or relating to pulse code communication systems
IPC: H03K3/286
Filed: 1960-01-06
Abstract: 935,293. Pulse code modulation systems; transistor pulse circuits. WESTERN ELECTRIC CO. Inc. Jan. 6, 1960 [Jan. 19, 1959], No. 479/60. Classes 40 (5) and 40 (6). The output of a transmitter 2 is applied to a coder 4 which provides a pulse coded output (a), Fig. 1, which is supplied to a binary counter 6 providing an output (b). A differentiator 8 is connected to the output of the counter 6, and provides an output (c) equivalent to that shown at (a) but with alternate positive pulses reversed in polarity. At the receiver the signal is converted into the original binary code pulse train (d) by a full-wave rectifier 12, decoded at 14, and supplied to a receiver 16. At the repeater 10 the signal is applied via a line equalizer 22, Fig. 4, to a three-stage transistor amplifier 28, 30, 32, provided with negative feedback via resistor 58. The output of the amplifier is supplied via a transformer 62, full wave rectifiers 70, 72, and a filter tuned to the basic pulse repetition frequency, to a " clock " amplifier 74 and the resulting positive clock pulses are applied to the cathodes of diodes 80, 82, which in the absence of clock pulses are forward biased by positive voltage 84. The signals at terminals 68, 66 are applied to the cathodes of diodes 86, 96, respectively, and the arrangement is such that the flip-flop 90, 94, changes state each time a positive clock pulse coincides with a positive pulse from terminal 66 or 68. The collector of transistor 94 is connected to one side of the primary winding of transformer 102, the collector of transistor 90 being connected to the other side, and oppositely poled pulses (c) appear across the secondary. The transformer may be of the saturating type. In alternative arrangements a pair of transistor blocking oscillators replace the flipflop circuit. Specification 865,353 is referred to.

Title: Improvements in or relating to telephone exchange systems
IPC: H04M3/60
Filed: 1925-01-07
Abstract: 250,642. Western Electric Co., Ltd., (Deakin, G.). Jan. 7, 1925. Automatic and semiautomatic exchange systems; metering. - In a system in which a calling line is extended to a link circuit adapted to select an idle junction leading directly to a "B" operator at one one of a number of distant exchanges, the talking circuit is split by condensers at each end of the junction so that the junctions may be guarded from both ends. A calling subscriber is extended by a link circuit, Fig. 1, to a free junction leading to a " B " operator's position, Fig. 2, at a wanted distant exchange, as described in Specification 250,644. When the idle junction shown is engaged, the outgoing test relay JT1, Fig. 1, is energized over a resistance R, Fig. 2, in the test wire, and a circuit is closed over the b wire for high and low resistance relays JB1, JB2 at the " B " operator's position and the supervisory relay S2 in the link circuit. Only the relay JB1 responds and lights the calling lamp CL. The relay JT1 energizes relay JT2 which shunts the high-resistance winding of relay JT1 with its low resistance winding to guard - the junction. The " B " operator throws her listening key, enquires the wanted number, and inserts the terminating plug into the multiple jack of the wanted party, thereby energizing a a relay JC over the sleeve circuit. Relay JC extinguishes the lamp CL, lights a called supervisory lamp S2L, and connects up a supervisory lamp S1L, which however does not glow since it is disconnected by relay JB1. Relay SC also connects battery to the a wire of the junction, thereby energizing relay JA, which removes battery from the test wire c and de-energizes the test relays JT1, T2, Fig. 1. When the called party answers, supervisory relay S3 disconnects the called lamp S2L and shunts the May JB1, causing the response of relays JB2 and S2. Relay S2 energizes relay SM1, which prepares a metering circuit as described in the previouslymentioned Specification. During conversation talking current is supplied to the calling party over relay S1, and to the called party over relay S3. The junction circuit is balanced at its outgoing end by relays S2, JA and at its incoming end by relay JB2 and retardation coil RET. At the end of conversation, when the calling party hangs up, the call is metered and the link circuit released, as described in Specification 250,644, thereby de-energizing relay JB2 and lighting the calling supervisory lamp S1L. When the called subscriber hangs up, relay S3 relapses and lights the called lamp S2L. As long as the plug remains in the multiple jack, the relay JA remains energized and disconnects battery from the c wire to hold the junction busy. When the operator takes down the connection relays JC, JA relapse and the junction is rendered available for another call.
