Title: Improvements in the manufacture phenols from halogenated aromatic hydrocarbons
IPC: C07C37/02
Filed: 1933-03-09
Abstract: The hydrolysis of halogenated hydrocarbons with alkali under pressure to produce phenols is conducted in the presence of sodium or potassium chloride, e.g. by using an alkali hydroxide solution containing alkali chloride obtained from the electrolysis of an alkali chloride solution.  The presence of alkali chloride substantially reduces the quantity of phenol remaining dissolved in the reaction mixture, after the phenol precipitated by neutralisation or acidification has been separated.  Examples are given of the preparation of phenol by heating chlorobenzene with a solution of sodium hydroxide or sodium carbonate containing sodium chloride, the reaction being effected under pressure in the presence of a little copper powder; after acidification with hydrochloric acid, the precipitated phenol is separated and the traces of phenol dissolved in the liquor then removed by one extraction with chlorobenzene. Specification 103,664, [Class 32, Distilling &c.], is referred to.

Title: Improvements in or relating to thermionic oscillation generators
IPC: H03B5/34
Filed: 1933-03-09
Abstract: 402,637. Valve generating circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Marconi House, Strand, London.- (Assignees of Goddard, De W. R. ; Riverhead, Long Island, New York, U.S.A.) March 9, 1933, No. 7208. Convention date, March 14, 1932. [Class 40 (v).] A generator adapted to produce oscillations at either of two frequencies comprises a thermionic valve 2 associated with two resonant circuits, e.g. containing piezo-electric crystals A, B, in such a manner that the voltage applied to the valve electrodes determines which of the resonant circuits shall control the frequency. The valve 2 is a four-electrode valve, the plate and electrode 8 deriving their voltage from a potentiometer 14. When switch 24 contacts with contact a, the electrode 8 acts as a screen grid and the crystal A, coupling the plate and control grid, determines the frequency. When the switch 24 contacts with contact b, the electrode 8 is at a higher potential than the plate anc acts as an anode, the crystal B, coupling the electrode 8 and the control grid, controlling the frequency. In this latter case, the oscillations are transferred to the output circuit by the crystal A and by inherent coupling between the plate and the electrode 8. The oscillations may be fed to a buffer amplifier 28 or frequency multiplier and modulated by variations in voltage applied to the electrode 34 of a valve 30. Code signalling may be achieved by switching from contact a to contact b and secret signalling may be attained by a periodic change in frequency, so that two receivers, one tuned to each frequency, will give the total signal after combining their outputs.

Filed: 1944-04-19
Abstract: 576,981. Washing-machines. BRITISH THOMSON-HOUSTON CO., Ltd. April 19, 1944, No. 7216. Convention date, April 21, 1943. [Class 138 (ii)] In a washing machine having a spinner basket 6 in which clothes may be centrifugally dried after washing, a stream of liquid from a nozzle 13 is directed on to a deflector which splashes it over the side walls and base of the basket immediately prior to drying. This clears the basket of suds, and prevents suds-lock during spinning. The deflector, in the construction shown, is an annular flange 20 at he base of an upper section 3 of the outer casing. The machine is filled with water by opening a valve 14 connecting the nozzle 13 with a supply pipe 12, the water passing to the bottom of the casing from which it is immediately withdrawn by a pump 15 and passed by way of a nozzle 18 to the basket. When the basket is full, surplus water passes out through overflow apertures 7 back to the bottom of the casing, so that a float 21 lifts to operate valve 14 to cut off the supply. A two-way valve 17 enables the dirty liquid to be pumped out by way of a discharge pipe 19 after drying.

Abstract: 1342848 Continuous casting CONCAST AG 18 Feb 1972 [22 Feb 1971] 7746/72 Addition to 1173755 Heading B3F [Also in Division G1] The light intensity at a secondary cooling zone 8 of a continuous casting plant is monitored, e.g. by photo-electric cells 14 on a chamber 15 enclosing the zone, so that any changes due to molten metal breakout are compared with predetermined values and when a value is exceeded, electric signals are obtained for controlling the plant. Upon a first value being exceeded, automatically flow of melt into the mould 6 is shut off and withdrawal by rolls 12 briefly interrupted and then resumed at reduced speed. If the light intensity then falls, a reduced melt flow is started and finally normal casting is restored in stages if the breakout is cured by the cooling. If a second light intensity value is exceeded, the withdrawal is further reduced and the secondary cooling water flow increased. If a third value is exceeded, i.e. the preceding measures have not stopped the breakout, the withdrawal is completely stopped, an alarm is set off and the casting operation is switched to manual control. If the secondary cooling zone uses cooling plates or grids, the breakout may be covered by a surface and thus assisted in resolidication.
