Abstract: 206,128. Roucha, E. Oct. 30, 1922, [Convention date]. Void [Published under Sect. 91 of the Act]. Drawings to Specification. Fluid-actuated valves.-In apparatus for recording or measuring variations to a valve, e.g. the flow of steam through a pipe, the variations upset the equilibrium of mechanism associated with the pipe and thereby affect a constantly moving member which restores the mechanism to its position of equilibrium and simultaneously operates a local indicating apparatus for measuring the variations. In one arrangement, in which the flow of steam is regulated, the restoring mechanism and the indicating apparatus are identical with that described in Specification 206,127, [Class 69 (i), Hydraulic apparatus &c.]. The restoring action, however, is assisted by a dashpot whereby unsteady operation of the apparatus is prevented.

Abstract: 277,714. Goldschmidt, R. B., and Coulier, S. Sept. 20, 1926, [Convention date]. Materials and compositions for making coke and other products. - Peat mixed with alkali, alkaline-earth, or metal compounds such as oxides, hydrates, carbonates, nitrates, or sulphide and active carbon is subjected to wet or dry carbonization to yield mixtures which on treatment at high temperatures with free nitrogen or its compounds such as ammonia or amines yield cyanides, cyanamides or nitrides, and a residue of active carbon. Raw peat mixed with the alkali &c. is formed into a paste which may be pressed to form rods which are dried prior to carbonization. The alkali &c. increases the formation of ammonia and the yield of tar. Catalysts for the subsequent nitrogenation such as iron, manganese, chromium, nickel, cobalt or their oxides or halogen compounds such as sodium chloride or fluoride or alkaline earth compounds which do not become nitrogenized, or substances which increase the activity of the carbon such as zinc or magnesium chloride, oxide or phosphate, titaniferous compounds, &c. may be added prior to the carbonization. The carbonization may be effected in a current of gas such as carbon monoxide or dioxide, nitrogen, chlorine, hydrogen or water vapour to increase the activity of the carbon. The residual carbon is added to the raw materials to increase the porosity of the carbonized product. The nitrogenation may be effected at 950-1000‹ C. at a pressure of 1-2 atmospheres, and may be carried out in a. vertical or inclined furnace, the upper part of which serves for the carbonization.

Title: Improvements in or relating to synchronising signal separator circuits

Abstract: 859,881. Pulse discriminating circuits. FERNSEH G.m.b.H. Aug. 8, 1958 [Aug. 9, 1957], No. 25491/58. Class 40(6). In a circuit for separating long pulses from a mixture of short and long pulses the mixed pulses are applied to a resonant circuit having a period of oscillation greater than twice the duration of the short pulses but less than twice the duration of the long pulses, the resonant circuit being effectively connected in shunt with a rectifier and supplying potentials to a circuit which selects only the resulting pulses which are of greater amplitude and correspond with the desired pulses. In the figure mixed line and frame television synchronizing pulses are applied to the input of a valve 24 having a circuit 21 coupled to its screen grid circuit tuned to a frequency greater than that corresponding to twice the line pulse duration and less than a frequency corresponding to twice the frame pulse duration. The line pulses cause the circuit to ring for one-half cycle, the other half cycle being damped by rectifier 26. The arrangement is such that the tuned circuit is still discharging through the rectifier when the next line pulse occurs and accordingly the line synchronizing pulses produce only small amplitude pulses across the tuned circuit. The frame pulses also cause the circuit to ring but are sufficiently long for the amplitude of the voltage across the tuned circuit to build up to a much higher value so that the frame pulses may be selected by a limiter arrangement 30, 31. A high pass filter 33, 34 may be connected in the output circuit to reduce the components of the output corresponding to the harmonics of the frequency of the tuned circuit. Line pulses may be extracted from the anode circuit by a conventional network 35, 36. The frequency of the tuned circuit may be equal to the line frequency or, where there are several different television standards, to the mean of the line frequencies (e.g. about 15 kc/s.). In an alternative circuit (Fig. 1, not shown) the tuned circuit is connected directly in the anode of a valve.
