Abstract: 1,233,971. Furnace carbon black. ASHLAND OIL Inc. 13 Jan., 1969 [12 Jan., 1968], No. 1895/69. Heading C1A. Furnace carbon black is produced in a tunneltype reactor by thermal decomposition of a fluid hydrocarbon feedstock, the process being characterized by quenching the reaction mixture with a quenching fluid, e.g. steam, in amounts which progressively increase from the influent end toward the effluent end of the reaction zone. Preferably, the angle at which the quench fluid is injected is an angle of less than 90 degrees with respect to the walls of the reaction zone, so as to form a continuous annular curtain of quench fluid along the walls of the reactor, and this angle progressively increases from the influent end toward the effluent end. The apparatus specified consists of a combustion zone 12 (Fig. 3) separated from the reaction zone by a restricted diameter choke 20. There are a plurality of quench injection points each being adapted to inject quench fluid in amounts and at angles which progressively increase 42, 46, 50 and 54 from the influent end to the effluent end of the reactor.

Abstract: 1,252,729. Automatic control. CORNING GLASS WORKS. 29 April, 1970 [29 April, 1969], No. 20529/70. Heading B3B. [Also in Divisions F1 and G4] The positions of X and Y slides 5, 15 on a work-table 6 of a machine tool are controlled by a fluidic arrangement for controlling the actual position of the slide in response to fluidic desired-position commands, the arrangement comprising fluidic register means for storing a fluidic binary-coded indication of said desired position, fluidic transducer means for measuring the actual position of the object and for providing a fluidic binary-coded indication of the actual position, fluidic comparator means for comparing the fluidic binary coded indication of the actual position and the desired position to derive a fluidic indication of the error between the actual and desired positions, and fluidic means for altering the actual position responsive to said fluidic indication of said error. The fluidic transducer may be in the form of a rotary disc (25) (Fig. 2, not shown) having plateaus and notches and a plurality of fluid pressure probes mounted peripherally of the disc. The probes also include a signal output connection which receives a pressure rise when a plateau blocks the end of the probe. The probes are angularly spaced to provide a vernier division of a 36 degree angle of movement of the disc to initiate a binary-coded decimal signal as the disc is rotated by movement of a slide X or Y. The information of the desired position is stored in a paper tape having openings that are sensed by a reader 1. This information is fed to a comparator 8 which also receives the signals from the transducer 7. A counting device 7a or 17a is provided for recording the movements of the slides. The comparator 8 or 18 comprises an arrangement of fluidic devices connected in series (Fig. 6, not shown) having an input (60) and a number of control channels (A), (C), (E), (G) indicative of actual values, and oppositely aligned control channels (B), (D), (F), (H) indicative of desired values. Intermediate output channels (62), (64) pass signals depending upon whether a signal is present on one or both of a pair of aligned control channels. The Specification describes a number of fluidic devices (Figs. 3a-3h, not shown) and arrangements of these devices to provide binary coded decimal output signals (Figs. 4a-4f, not shown).

Abstract: 1,259,178. Pulse discriminating circuits. BURROUGHS CORP. 12 Aug., 1969 [30 Aug., 1968], No. 40164/69. Heading H3P. A pulse discriminating circuit, e.g. for recovery of binary data stored as NRZ pulses on magnetic tape, disc or drum, has provision for detecting low amplitude pulses (A at t2) lying between pulses of opposite polarity but not responding to low amplitude noise pulses (A at t4) not followed by a pulse of opposite polarity. As shown, signals A from a reading head 1 are amplified at 2 and fed to positive and negative threshold detectors 3, 5 giving waveforms D, C. A peak detector 4 gives a change in output (B) in response to each input peak. A bistable chain 14, 16, 18 is set by each coincidence of waveforms B, D and reset by each coincidence of waveforms B, C. Each time a pulse exceeding the threshold occurs, one of monostable multivibrators 8 or 9 produces an enabling signal for AND gates 10 or 11 that lasts for 1À5 bit periods (E, F). A second bistable chain 15, 17, 19 is arranged to change state in response to each threshold bit and also in response to each peak occurring in a time slot following a threshold bit. JK flip-flops 16...19 are arranged to step the states of circuits 14, 15 following each clock pulse I from source 20. A logic circuit 72 is arranged to couple the output of one of flip-flops 18, 19 to output N if the states of the bi-stable channels agree and, if the states of the channels fail to agree, to couple the second channel M to the output N. An interlock circuit 73 prevents the generation of more than one pulse following each required input signal. Modifications.-The clock pulses may be derived from the data. Different threshold levels may be provided for the first and second time slots following a threshold signal.

Abstract: 1290184 Diffraction gratings A JOBIN & G YVON 30 Sept 1969 [26 March 1969] 48039/69 Heading G2J A diffraction grating comprises a support having a concave spherial surface on which the grating lines are located at the intersection of the surface by a family of surfaces obtained as the loci of the maximum of luminous intensity upon the interference of two beams of light originating from two coherent point sources. The diffraction grating may be formed by forming a layer of uniform thickness of a photo-polymerizable resin on an optically polished support face, exposing the layer to the interference action of two point sources of coherent light to give a fraction of polymerized resin and a fraction of non- polymerized resin, and then removing one of the said fractions. The resin which is less than 2 microns thick, preferably 1À5 microns thick, may be a photo-resist type of resin. The two point sources may be selectively placed one at the centre of curvature of the support and the other elsewhere such as on the Rowland circle or at infinity. If desired one of the sources may be an image of a source located on the opposite side of the support. By selective positioning of the sources the interference of the two sources is a family of geometrical surfaces e.g. spherical, elliptical, parabolic, or hyperbolic. Several examples are given. A spectrum of a polychromatic source located in the same position relative to the grating as one of the original sources may be obtained by locating a screen along the geometrical curve passing through the original source points.

Abstract: 1311134 Automatic gain control GENERAL ELECTRIC CO Ltd 21 Sept 1971 [15 Oct 1970] 49024/70 Heading H4R In an automatic gain control of the type in which abnormal variations of a pilot signal are detected and cause the gain to be controlled in accordance with the pilot signal value immediately preceding its departure from normal value, and in which the gain is varied by varying the temperature of a temperature dependent resistor in the feedback path of an amplifier, a secondary control loop is provided, sensitive to the resistance of the feedback resistor, in order to hold the gain steady despite changes in the ambient temperature. As described the level of a pilot signal at the output of amplifier 12 is detected by filter 16 and rectifier 18 and normally controls the heating of a thermistor 30 in the feedback path of the amplifier 12 via a delay circuit 24 and memory 26. In the event of abnormal level variations in the pilot signals relay PF is operated, to open contacts PF1 so that the gain is controlled by the stored value of pilot signal in memory 26, as described in Specification 1,072, 222. In addition a secondary control loop operates in dependence of the value of the feedback resistor, as detected by circuit 36, to provide a control signal, to differential amplifier 28, operation in opposition to the normal control signal developed by the pilot, to tend to maintain the value of the resistance constant during the period that gain control is exercised by the stored value.
