Title: Improvements relating to control systems for regulating the co-ordinated filling and emptying of a number of tanks or containers
IPC: C02F1/00
Filed: 1941-10-21
Abstract: 552,771. Automatic control systems for filling and emptying tanks &c. PORTEOUS, W. K. Oct. 21, 1941, No. 13542. [Class 38 (iv)] [Also in Group XVII] Level of fluid material.-Relates to a control system or cyclic operation for two or more tanks such as T, E, F of which one, say F, is being filled, while another, say E, is being emptied and of which another T holds fluid under treatment 'for the period taken in filling and emptying the others, subsequently replacing tank F in the cycle of operation. A step by step motor 5, suitably actuating the inlet and outlet valves of the tanks, is energized by a relay Rf<SP>1</SP> when the maximum level in tank F causes a magnetic float to rise into a coil fc to produce electrical resonance with a parallel condenser G<SP>1</SP>. Alternatively similar devices responsive to minimum fluid level may cause actuation of the motor. To ensure that filling and emptying times remain equal a valve SV in the outlet manifold, for example, is operated by an impulse motor or electromagnetic means 1 M to a small extent in a correcting direction whenever the magnetic floats responsive to maximum level in a filling tank and minimum level in an emptying tank fail to lift simultaneously. In such case contacts on relays such as Re2 co-operate with contacts on relays such as Rf<SP>1</SP> to close one or other of two circuits passing through distributor switches on the shaft of motor 5 to energize a reversing switch for the motor 1M in an appropriate direction. The speed of a sewage pump SP may be adjusted for example, to determine the filling &c. time.

Patent GB-1066542-A (GB)
Title: Process for producing cycloalkyl-arylketones
IPC: C07C49/792
Filed: 1964-04-03
Abstract: Cycloalkyl aryl ketones are prepared by reacting an aromatic hydrocarbon and a cycloalkane carboxylic acid in the presence of polyphosphoric acid having a phosphoric anhydride content between 73 and 88% at a temperature at which the polyphosphoric acid is to some extent fluid and at a molar ratio between P2O5 and cycloalkane carboxylic acid of between 1 : 1 and 10:1.  The cycloalkane ring may contain 4-12 carbon atoms, and may be alkyl-substituted. The aromatic hydrocarbon may be benzene, toluene, xylene, ethylbenzene or cumene. The reaction mass may be heated and extracted with the aromatic hydrocarbon, or the mass may be diluted with water then extracted. The polyphosphoric acid is recovered and may be recycled after its phosphoric anhydride content has been restored to the desired level. The examples describe the preparation of cyclohexyl - p - tolyl - ketone, cyclohexyl - phenyl - ketone, cyclohexyl - (2,5 - dimethyl - phenyl)-ketone, cyclohexyl - (4-ethyl-phenyl)-ketone, cyclohexyl - (2,4 - dimethyl - phenyl) - ketone, cyclohexyl - (4 - isopropyl - phenyl) - ketone, cyclooctyl - p - tolyl - ketone, and cyclododecyl-p-tolyl-ketone.

Patent GB-577942-A (GB)
Title: Improvements in or relating to apparatus for generating electrical pulses
IPC: H03K5/06
Filed: 1941-10-28
Abstract: 577,942. Impedance networks. BLUMLEIN, D. (Representative of BLUMLEIN, A. D.). Oct. 28, 1941, No. 13833. [Classes 40 (iii) and 40 (v)] An artificial line or delay network .10 whose characteristic impedance varies along its length is used for modifying the shape of electrical impulses, the action being dependent on reflections from the mis-terminated end of the network and from intermediate points. The Specification contains a mathematical discussion which assumes first a flat-topped impulse and then a step potential applied to the network 10 from a source 12 and indicates the general nature of the resulting wave form across an impedance 11 at the same end as the source, the far end being terminated in an open-circuit or a short-circuit. When a load such as a magnetron to be fed with flat-topped impulses is shunted by the inductance of a transformer, the network may be employed for correcting the distortion introduced by the latter. It may also be employed for a similar purpose in an impulse generating arrangement in which an artificial line is periodically discharged by a gas-discharge tube to which it is connected through a protective inductance. In this case, the inductances of the graded sections of the network preferably diminish exponentially to the value of the inductance used in the artificial line, and the gas-discharge tube constitutes the mis-matched termination.
