Title: Improvements in the Production of Carbon-Black
Inventor: MOREL ROGER
IPC: C09C1/50
Filed: 1966-05-27
Abstract: 1,150,362. Carbon-black. R. MOREL. 27 May, 1966 [31 May, 1965], No. 23837/66. Heading C1A. Carbon black is produced by atomizing a liquid hydrocarbon, bringing it in contact with a hot gas within a combined space to crack the hydrocarbon into carbonblack and tail-gases, wherein the tail gases are freed of water vapour and combustible components and fed with air and a combustible gas to the confined space thus forming a hot gas. An inert gas may form part of the gaseous medium. The Figure shows a layout of an installation according to the invention. This Figure shows a combustion chamber 1, followed by a cracking antechamber 2a and cracking chamber 2. Pipes A and G deliver air and a combustible gas to the burner B. The liquid hydrocarbon is led into chamber 1 by an atomizer GT fed by a pipe T, which is pressurized by mechanical means. The gases produced, containing carbon-black in suspension, are quenched by quenching device 14 and pass through a tubular exchanger 4 which is used for heating combustion air which is fed to chamber 1. A temperature detector CT controls the temperature of air supplied to the combustion chamber. The gases from 4 pass through cyclones 5 and filters 6 to remove the carbon-black. The tail gases pass to cooler 10 where their water content is condensed. The tail-gases are mixed with fuel gas and burned in the incinerator 7. Combustion air is supplied to 7 by fan 9, after having passed through the cooler 10 where it becomes heated by the tailgases. The residual gas from 7 passes to the burner and part may be injected by compressor 13 into the atomizer GT. This latter supply may be controlled by valve V 2  so that the velocity of the atomized hydrocarbon particles may be controlled, and hence different grades of carbonblack may be produced. Residual gases may also be prepared by removing hydrogen and water from the tail-gases at the outlet of filters 6, and then converting the remaining carbonmonoxide to carbon dioxide. Alternatively, the tail-gases freed of their water of condensation may be passed to a catalytic bed whereby the carbon monoxide and hydrogen are oxidized, giving an inert gas.

Patent GB-440795-A (GB)
Title: Improvements in or relating to telephone pay stations for variously rated calls
IPC: H04M17/02
Filed: 1935-08-27
Abstract: 440,795. Automatic exchange systems. TELEPHON - APPARAT - FABRIK E. ZWIETUSCH & CO., GES., 6, Salzufer, Charlottenburg, Berlin. Aug. 27, 1935, No. 23940. Convention date, Jan. 11. [Class 40 (iv)] [See also Group XVIII] The automatic pay station described in Specification 430,339 for operation in connection with an exchange system wherein coin insertion on both local and short distance calls is automatically checked against the digits dialled, is adapted to be readily modified to operate in a system wherein only local calls are made automatically, e.g. by coin control of shunt on the impulse springs, the more expensive calls being dealt with by an operator. The modifications comprise (1) arranging that coin operated contacts gk10 for the unit fee normally shunt the impulse springs nsi but are permanently opened by a unit coin, (2) the provision of an additional switch hook contact 3HU and (3) the provision of jumper connections associated with terminals 1 to 13 to alter the connections from Fig. 2 (fee checking as described in the prior Specification) to Fig. 3 (local automatic only). Mechanical modifications for the control of contacts gk10 are shown in Fig. 1 and comprise the addition of parts 201-207. The spring 40 is slotted at its upper end to engage lever 201 biassed counter-clockwise by a spring so that when lever 36 is rotated counter-clockwise by a coin passing through channel 33, instead of spring 40 being operated by cam 39 to send an impulse as described in the prior Specification, the spring contacts are held open by the engagement of spring 40 with shoulder 204 on lever 201. When the receiver is taken off the hook, bar 4 drops and pin 206 thereon passes a spring controlled trip lever 207 without effect, but when bar 4 rises on replacement of the receiver lever 201 rotates clockwise with 207 and releases spring 40. To convert to the fee checking arrangement, the pin 202 carrying the levers 201, 207 which has a squared end mounted in a side plate, is removed and replaced after rotation through 90. Circuit modifications. In the prior Specification, the coin-signalling circuit (light lines, Fig. 2) is normally connected to line and is replaced at contacts vk by the telephone and dial set (heavy lines) when the dial is moved off normal. The jumper connections are so modified in Fig. 3, that the telephone and dial set are connected to line and contacts gk10 of the signalling circuit are used to shunt the dial springs. To obtain a short or long distance connection, a unit coin is inserted to remove the dial shunt as in a local call, and the operator is dialled. When she has set up the connection she calls for further coins which operate gongs (unit fee gong is shown at 32). Coin contacts gk10 are not operated and coin contacts gk50, Fig. 3, operated by coins of higher value as described in the prior Specification, are ineffective.

Title: Improvements in electron beam tubes
IPC: H01J25/49
Filed: 1961-07-04
Abstract: 950,118. Space charge wave tubes. SIEMENS & HALSKE A.G. July 4, 1961 [July 4, 1960], No. 24104/61. Heading H1D. An electron beam parametric amplifier comprises successively an electron gun 1, a pumpfrequency density modulator 3, a periodic delay line 4 and a collector 7, wherein the delay line supports only waves in the frequency band of input signals applied thereto, an idler frequency band constituted by the difference between the pump and input signal frequencies and the frequency band between the idler and input frequency bands; and wherein the delay line and the electron beam are so dimensioned that the phase shift of the modulated wave associated with the electron beam, relative to the phase of a wave manifested on the delay line and having a frequency equal to half the pump frequency, from one interaction region to another, is always 180 degrees or a whole number multiple of 180 degrees. In operation, a backward or forward fast space charge wave associated with the modulated electron beam interacts with the wave manifested on the delay line which for optimum degree of amplification is the arithmetic mean of the signal and idler frequencies, i.e. half the pump frequency. Broad band amplification is possible if the pump frequency is adjusted to correspond to the input frequency so as to enable this optimum frequency to be used, and if the delay line is or capable of only supporting the above frequency bands. The delay line is preferably interdigitated and may be damped to minimize undesirable self oscillations. The pump-frequency density-modulator may be a single cavity as shown, a single circuit double-gap resonator tuned to the pump frequency which is self exciting, or two single gap resonators coupled together by a phase shifter and excited at the pump frequency so that only the fast space charge wave is excited on the beam. Noise is minimized by special dimensioning of the delay line and the electron beam so that the dispersion curves of space charge waves do not touch the dispersion curves of the waves on the delay line and intersect them at as few points as possible.

Abstract: 698,892. Retractive switches; snap-action arrangements. DEWHURST & PARTNER, Ltd., and DEWHURST, M. Oct. 5, 1951 [Oct. 5, 1950], No. 24342/50. Class 38 (v) ' A snap-action retractive switch, primarily intended to form part of a reversing controller for a crane hoist, has a contact-carrying shaft 14 which is restrained from movement by pawls 22, 23 carried by a plate 19 secured to the shaft until a coil spring 20 has been strained sufficiently to produce a snap-action movement of the shaft 14. The ends of the coil spring extend on each side of tongues 15b, 19b, the tongue 15b projecting from a cam plate 15 on the operating shaft 13 and the tongue 19b extending from the plate 19. On movement of the operating handle 10 to either side of its central position, the shaft 13 turns the plate 15 so that the tongue 15b moves relatively to the tongue 19b and strains the spring 20 until a cam plate 24 secured to the shaft 13 releases that pawl 22 or 23, which was preventing rotation of the shaft 14, from engagement in one of the indentations in a fixed bracket 21. The spring 20 is then able to move the tongue 19b and so turn the shaft 14. The turning of the cam plate 15, forces a roller 16 to ride up one side of a groove 15a in the plate, so that when the handle 10 is released, a spring 18 acting on a lever 17 carrying the roller 16, is effective to restore the cam plate 15, shaft 13 and handle 10 to their central position, so causing the return snap-action movement of the shaft 14 in the manner described above.

Abstract: 852,628. Coal-cutting. OELLRICH, A., [trading as MASCHINENFABRIK UND EISENGIESSEREI A. BEIEN]. July 16, 1959 [July 31, 1958], No. 24543/59. Class 68(1). A coal-cutting and conveying apparatus has, at or near; floor level, cutters 8 on articulated guide rails 7, and cutters 8a on articulated guide rails 7a at a higher level, preferably near the roof, the feed of the cutters 8, 8a into the coal face being effected in alternation by a fluid pressure cylinder and piston 3, 5 associated with each of a number of auxiliary props 2. The props 2, which are independent of the normal support system, may be of a mechanical nature, e. g., with toggle lever clamping, but as shown are fluid-pressure operated. When the props are extended, the cylinders 3, which are each mounted on a plate 4 secured to the foot of the prop, are operated to project the rods 5 through the bottom of the props and to push the cutters 8, through the conveyer 1, into the coal face. The props 2 are now relieved and the cylinders 3 are operated in reverse so that the plates 4 are pulled nearer to the coal face and the cutters 8a are given a cutting feed. An arm 9 carried by each prop 2 is pivoted with play at 10, and the guide 7a is connected to a supporting rail 7b carried from the arms 9 by pins 11 and cushioned by cup washers 12. In a modification, the height of the support rail 7b is adjustable by securing it by wedges and clamping members to unsymmetrical heads of the pins 11 in one of two positions, and in addition by having two holes at different levels in the supporting arms 9 to receive the pins 11 at one level or the other. In a further modification, the arms 9 do not contact the roof but are vertical adjustable and clampable on the upper parts of the props 2. The cutters 8, 8a are drawn to and fro along the working face.
