Title: Programmed switching of servo error signals in tape apparatus synchronising systems
IPC: G11B19/28
Filed: 1966-03-28
Abstract: 1,134,481. Automatic speed control. AMPEX CORP. March 28, 1966 [March 29, 1965], No.13686/66. Heading G3R. In a magnetic video tape record/replay system in which the rotation of a magnetic head drum is retro-actively controlled, three different error signals are produced and selection is made between them by logic circuitry in a predetermined sequence. The three signals are phase errors between (i) tachometer signals and a reference; (ii) veritcal sync. pulses from tape and a reference; (iii) horizontal sync. pulses from tape and a reference, and they correspond to course, medium and fine control respectively. In an automatic mode of operation control is switched through the sequence as each step becomes effective, with repetition from step (i) in the event of pull-out at a later stage. Additional conditions, such as operation of tape guide relays and effective operation of capstan servocontrol must be met before change over from (i) to (ii) can occur. Different modes of operation, selected by a manual switch, enable the sequence to be terminated at any step, or step (ii) may be omitted. The reference signals may be obtained from a separate television signal or from line sync. signals.

Title: Direction-finding apparatus
IPC: G01S3/48
Filed: 1960-04-20
Abstract: 937,105. Radio and sound direction-finding. NIPPON ELECTRIC CO. Ltd. April 20, 1960 [April 21, 1959], No. 13874/60. Drawings to Specification. Class 40 (7). In apparatus for determining the direction of incoming sonic or electromagnetic waves comprising a rotatable array of receiving elements providing a resultant output having a maximum for a given orientation of the array relative to the direction of the incoming waves, the signal/ noise ratio of said resultant is improved by deriving from the output from each element a signal representing the cross-correlation function of said output signal with a standard signal and adding said cross-correlation signals to provide said resultant output. The crosscorrelation function of a signal h e (t) with a standard signal h s (t) is defined as The standard signal may comprise the output from one of the receiving elements or, in the case of a radar type system, a signal derived from the transmitter. The relative amplitudes and phases of the cross-correlation signals may be adjusted, i.e. " shaded," in the combining circuit to reduce side lobe effects. The invention is applicable to linear or circular arrays.

Title: Improvements in or relating to the separation of hydrocarbons with molecular sieves
IPC: C10G25/03
Filed: 1958-05-02
Abstract: Straight chain hydrocarbons are separated from other hydrocarbons by selectively adsorbing the normal hydrocarbons on a molecular sieve and subsequently desorbing the adsorbed hydrocarbons by an oxygen-containing gas at elevated temperatures whereby a minor proportion of the adsorbate is burned; preferably not more than 3% by weight of adsorbate is burned.  The molecular sieve is preferably one having pore openings of 5   and the hydrocarbon mixture to be separated is contacted with it in the vapour phase at 100-850 DEG F., 0.1 mm.-500 p.s.i.g. and a feed rate of 0.1-10 vol./vol./hr., if desired with an inert carrier gas such as nitrogen, carbon dioxide or light hydrocarbons.  The adsorption vessel is preferably purged by applying a vacuum at the end of the adsorption cycle and desorption is then carried out with oxygen or air or a gas containing at least 1% by volume of oxygen with an inert non-combustible carrier gas such as nitrogen or carbon dioxide preheated to 600 DEG  F. or higher to initiate combustion.  A moving hot front is formed, its temperature being up to 1600 DEG  F., but preferably 800-1200 DEG  F., the average bed temperature during desorption being 600-1000 DEG  F. Desorption pressures may be 0.1 mm. -atmospheric.  The effluent is cooled to liquefy hydrocarbons which are separated from the combustion products.

Abstract: 119,228. Keene, A. D. Sept. 5, 1917. [Convention date]. Systems for continuous current only; master control systems; electric braking.-Relates to the control of motors for operating the electrodes of an electric furnace. In the arrangement partly shown, the furnace has a conductive hearth 2 and two upper electrodes 3, 3', each adjusted by a motor, one of which is controlled in accordance with current variations, and the other in accordance with pressure variations. The pressure-controlled motor connexions are omitted; they are similar to those of the current-controlled motor 4. A resistance 40 shunts the current-controlled arc. In series with the shunt control solenoid 20 are two resistance 29, 30, the latter being regulable and the other being controlled by a short-circuiting switch 33 mechanically connected to a handswitch 28 by which a part of the primary winding of the supply transformer 26 can be cut out. The current control solenoid 12 is adapted to close a direct current circuit through a switch 18 or 19, which closes a second circuit from the same supply mains 39 through the regulating motor 4 in one or the other direction. When both switches are open and the motor is still running, a solenoid 49 in the armature circuit closes a braking circuit through a resistance 52. Mechanical interlocks 54 - - 56 prevent the simultaneous closure of the braking circuit and the switch operated by either relay solenoid 18 or 19.
