Abstract: 517,163. Automatic stabilizing control systems. SIEMENS APPARATE UND MASCHINEN GES. April 14; 1938, No. 11584. Convention date, Sept. 8, 1937. Addition to 489,836, [Group XXXIII]. [Class 38 (iv)] [Also in Groups XXXIII and XXXVIII] Attitude.-A stability tank of the activated type, either for reducing rolling or correcting list, has the pitch of the actuating propeller varied in accordance with the angle of heel of the ship and the difference of water level in the two tank arms. These variants are transmitted in the form of electric voltages to a< >magnet 29 controlling the servomotor 50 through the power amplifier 43, these being operated by hydraulic power supplied by the pump 53. The voltage corresponding to the difference of water level in the tank arms is tapped from the voltage divider 40, the moving contact 39 being moved by the diaphragms 33, 34. The motor 21 which moves to correspond to the angle of inclination is controlled by the voltage difference between the contact arms 18, 20, one moved by the link 24 connected to the motor itself, and one by the angle of roll indicator 16. The motor 21 moves the contact arm 28 to provide a voltage from the voltage divider 26 to correspond to the angle of heel. A voltage corresponding to angular velocity of roll may also be added to the control magnet 29. The air valve 6 and the cock 66 are operated by hydraulic pressure under the control of the solenoid 56 which is de-energized when the ship is upright or when either of the tank arms are full. The solenoid 41a prevents the propeller 13 from becoming overloaded. In a modification alternating current voltage is employed and the system is used to reduce rolling by the adoption of a voltage control corresponding to the angle of roll. Specification 517,166 is referred to.

Title: Production of chlorinated para-xylene derivatives
IPC: C07C17/12
Filed: 1944-06-19
Abstract: Nuclear chlorinated p-xylylene dichlorides containing from 1 to 4 nuclear chlorine atoms are obtained by treating p-xylene with chlorine in the presence of a chlorination catalyst to introduce the desired number of nuclear chlorine atoms and then treating the product, or the separated products of intermediate chlorine content, with chlorine in the presence of actinic radiation and of an inert organic liquid diluent to introduce one chlorine atom into each side chain.  Ferric chloride and iron filings are specified catalysts.  In examples: (1) chlorine is passed into p-xylene in the presence of fine iron filings at about 60 DEG  C. until the desired amount of hydrogen chloride has been evolved. The bulk of the product is 2-chloro-p-xylene which is purified by distillation and treated with chlorine under reflux in the presence of carbon tetrachloride diluent under irradiation from a tungsten filament until the desired amount of hydrogen chloride has been evolved.  The resulting 2-chloro-p-xylylene dichloride is purified by distillation and supplemented by that obtained from further chlorination of the monochlor-p-xylxyl chloride and other low boiling compounds also formed and separated by distillation. (2) Nuclear chlorination is effected as in (1) but at a temperature of 60 to 100 DEG  C. to yield after distillation a mixture of 2.5-dichloro-p-xylene and 2,3-dichloro-p-xylene which is supplemented by that obtained from further chlorination of the lower boiling fractions, mainly 2-chloro-p-xylene also formed. The mixture is fractionally distilled and crystallised to obtain pure 2,5-dichloro-p-xylene which is chlorinated in each side chain as in (1).  (3) Nuclear chlorination is effected as in (1) but the chlorine is introduced in small increments at 100 DEG  C. to yield after fractionation 2,3,5-trichloro-p-xylene which is chlorinated in each side chain as in (1).  (4) Nuclear chlorination is effected as in (3) but after the quantity of chlorine required for the preparation of the trichloride has been introduced to reaction is interrupted and an amount of carbon tetra chloride is added in amount equal to that of the xylene present at the beginning to maintain the semi-fluid state.  A solution of chlorine in carbon tetrachloride is added to the reaction mixture until the theoretical quantity of chlorine necessary to convert the product to the tetrachloride has been added.  The resulting tetra-chloro-p-xylene is chlorinated in each side chain as in (1). Specification 114,645, [Class 2 (iii)], is referred to.  The Specification as open to inspection under Sect. 91 describes also such a process without the use of an inert organic liquid diluent. This subject-matter does not appear in the Specification as accepted.
Patent GB-745159-A (GB)
Title: Process for the production of terephthalic acid and phthalic acid
Filed: 1953-04-27
Abstract: Phthalic and terephthalic acids are produced by converting straight-chain olefins having 2, 4 or 6 carbon atoms in the molecule or a mixture of branched pentene, CH3.CH(CH3).CH=CH2, and propene into octenes by the process of Specifications 713,081 and 742,642, aromatizing these octenes to yield mixtures containing o-xylene and p-xylene and substantially free from m-xylene, and oxidizing the o- or p-xylene.  The octenes which are formed have the carbon structures <FORM:0745159/IV(a)/1> , <FORM:0745159/IV(a)/2> or <FORM:0745159/IV(a)/3> and include, for example, 2-ethylhexene-1, 2 - methyl - 5 - dimethylpentene - 1, 2 - isopropylpentene-1 and n-octene. Aromatization may be effected in the presence of a chromium-containing catalyst, e.g. chromic oxide.  The major proportion of p-xylene is separated by deep cooling, preferably after the addition of methanol, the p-xylene crystallizing out. The liquid residue is separated by distillation into p-xylene or a mixture thereof with ethyl benzene, and o-xylene.  Terephthalic acid may be obtained by oxidation of the p-xylene with potassium permanganate or with air in the presence of cobalt naphthenate. Phthalic acid anhydride may be obtained from o-xylene by oxidation with air using tin vanadate as catalyst.  Specification 623,836 also is referred to.

Title: Improvements in or relating to radio direction finding installations
IPC: G01S1/02
Filed: 1937-04-23
Abstract: 494,263. Directive wireless signalling. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., and FALLOON, S. W. H. W. April 23, 1937, No. 11735. [Class 40 (v)] In a radio direction-finding installation in which the direction is indicated on a cathode-ray screen, the cathode-ray is made to travel a circular path in synchronism with a continuously rotatable wave collector, and when the signal input differs from a predetermined limiting magnitude, the cathode-ray makes a radial deflection, thus indicating the direction of the received signal. The aerial system may comprise two parallel opposed frames rotating about an axis midway between them. In Fig. 1, a double condenser 4 is connected in parallel across the opposed frames 1., 2 and is tuned through a vertical operating rod 5. The input signals across the condenser 4 are coupled from the shielded leads 7, 8, which rotate with the aerial, to the stationary receiver 13 through condenser couplings 9, 11 and 10, 12. Frictional coupling (brushes and slip rings) or inductive coupling may be employed. The receiver 13 includes a non-rectilinear device, e.g. a valve stage operating at grid saturation, so that the receiver output is constant over a wide range of input signals above a predetermined value. This output is applied to the " signal winding " 19b of the cathode-ray tube 18 and a constant-current source 22 is connected to the " radius winding " 19a such that the deflection effects are opposed. The two windings are rotated in synchronism with the aerial so that the cathode-ray traces out a small circle and makes a deflection when the receiver output drops below the predetermined value corresponding to the aerial being in a zero signal position with respect to the station being received. A rotating loop gives two such minima, Fig. 6, but the system may be used with the rotating goniometer of a Bellini- Tosi or Adcock system combined with an open aerial, in which case the 180‹ ambiguity is removed. Specification 468,918 is referred to.
