Inventor: METHLEY IAN
IPC: F01L13/00
Filed: 2007-03-13
Abstract: A valve system for an i.c.engine allows a secondary valve event, eg to provide internal EGR, to be selectively disabled without requiring a continuously variable valve system. The system comprises two valves 10 and 22, a first cam 20 acting on the first valve 10 by way of a rocker 12 pivotable about a fixed pivot axis and a second cam 36 having at least two lobes and acting on the second valve 22 by way of a second rocker 24 pivotable about an eccentric 26. The second of the two lobes of the second cam 36 is arranged to open the second valve 22 at a time that the first valve 10 is opened by the first cam 20. A selectively operable latching mechanism 50 latches the eccentric 26 in a fixed position in which each of the cam lobes of the second cam causes the second valve to open. When the latching mechanism 50 is released, a coupling between the eccentric 26 and the first rocker 12 causes or permits the eccentric 26 to move during the opening of the first valve 10 in a sense to oppose the lifting of the second valve 22 by the second lobe of the second cam.

Title: Improvements in or relating to the destructive hydrogenation of coal, oils and the like
IPC: C10G1/06
Filed: 1929-04-02
Abstract: 331,548. Harrison, C. F. R., and Imperial Chemical Industries, Ltd. April 2, 1929. Hyrdrogenation, destructive:-Hydrogen for use in the destructive hydrogenation of coal, oils &c. is heated under pressure by converting a portion of it into methane by an exothermic reaction, in the presence of a catalyst, with carbon monoxide which is either present in the gas or is added for the purpose. When water gas is employed the gas is catalysed with steam to convert most of the monoxide to dioxide, leaving 3 to 5 per cent of the carbon monoxide; the dioxide is removed by washing with water under pressure. The gas is then further compressed to 200 atmospheres and heated from 250‹ to 400‹ C., e.g. by heat exchanges and, after the reaction referred to, is passed to the hydrogenation vessel, its temperature having been raised to about 500‹ C. The heat in excess of the average hydrogenation temperature is employed to counter balance any losses in the reaction chamber. The vessel in which the carbon monoxide reaction is effected may be contained in the hydrogenation chamber. In this case, the gaseous mixture may be preheated by passing it into an annular chamber inside and adjacent to the high pressure walls of the hydrogenation chamber; further preheating may be effected by utilizing the heat of the hydrogenation products. A gas consisting of 97 per cent of hydrogen and 3 per cent of carbon monoxide at a temperature of 300‹ C. and a pressure of 200 atmospheres is raised by the method described to a temperature of about 500 C., the reaction temperature.being between 420‹ and 480‹ C.; methane in the residual gases is removed by washing with oil, the recovered methane being converted to hydrogen by known methods, e.g. high temperature cracking. Specification 249,519 is referred to.

Title: Method of and apparatus for television reception and the like
IPC: H04N7/16
Filed: 1961-03-22
Abstract: 941,916. Pay television apparatus; radio receiver coin control arrangements. I. S. BLONDER, and B. H. TONGUE. March 22, 1961 [Aug. 26, 1960], No. 10474/61. Headings H3Q and H4L. Relates to apparatus, for use in conjunction with a television receiver adapted to receive a combination consisting of frequency displaced amplitude modulated picture signals and frequency modulated sound signals, which includes an amplifier for amplifying the combination of signals, and a frequency discriminator operating above a predetermined threshold value of input signal taken from the amplifier to reject amplitude modulation and to detect frequency modulation so as to produce a desired sound signal. Included in the apparatus are a narrow band network containing impedance elements selectively tuned to the picture carrier frequency and means for optionally inserting the network in circuit with the amplifier to render the picture signal unintelligible, the network being arranged to cause sufficient attenuation at the picture carrier frequency to reduce the input signal to the discriminator below its threshold so as to render the discriminator incapable of rejecting amplitude modulation and consequently producing a distorted sound signal. Fig. 1 indicates a television receiving system with an aerial feeding several receivers. Each receiver conventionally contains I.F. stages 11 followed by a video amplifier 11<SP>1</SP> from which a conventional picture channel 15 delivers the appropriate signals to the television picture tube, and a second channel 29 removes the amplitude modulation representing the vision signals in limiter 31 and then detects the frequency modulated sound signals. Between the aerial feeder and the first conventional stage are included two filter networks H, the transmission characteristics of which are equal, and opposite in phase, thus producing infinite attenuation-a so-called " cancellation trap." Both networks are selectively and narrowly tuned to the video carrier frequency having a bandwidth of about 30 kc/s. This has the effect, when the networks are in circuit, of distorting the picture signal so as to render it unintelligible. The filter circuits are further adjusted to provide at least 40 db attenuation so that the amplitude of the signal entering the limiter 31 is insufficient to be limited in the stage and provides an insufficient signal to allow the ratio detector 3 to discriminate against amplitude modulation. Hence the sound signal obtained at the loud-speaker is highly distorted. The narrow bandwidth of the cancellation trap means that signals in closely adjacent channels will be received without distortion. The switches 6 and 8 which switch out the filter circuits to allow undistorted reception are operated by a coin - operated mechanism diagrammatically indicated in the Figure.
