Title: Process for separating ether out of mixture of ether and aqueous alcohol
IPC: C07C41/38
Filed: 1938-01-28
Abstract: <PICT:0493420/IV/1> Ether is separated from single or multiphase mixtures of ether and aqueous alcohol by means of an inert solvent of ether which is insoluble in and lighter than aqueous alcohol.  The solvent-ether layer may then be freed from alcohol by washing with water and the ether separated from the solvent by fractional distillation. Suitable solvents are benzene, petroleum ether, and benzine.  The ether-alcohol mixture may be diluted with water before adding the solvent.  The process may be intermittent or continuous. The ether-alcohol mixture is led from a tank A by pipes a, b to the upper part of a column C, water being added if desired, by a pipe c. Solvent such as benzine is supplied by a pipe g; aqueous alcohol is withdrawn at h and the solvent-ether mixture passes by a pipe i to a washing column D to which water is supplied by a pipe k, the washed solution leaving by a pipe l.

Title: Improvements in method of and apparatus for purifying oil
IPC: C10M175/00
Filed: 1931-01-29
Abstract: Hydrocarbon oils, such as used transformer oil, are freed from gases and moisture by spraying the heated oil under high pressure into a chamber maintained at a low pressure.  Used <PICT:0371484/III/1> <PICT:0371484/III/2> <PICT:0371484/III/3> dissolved gases &c. which are drawn off through a pipe 75 into a vessel 78 in which entrained oil is separated from the gases which are finally exhausted through an outlet 80.  The degasified oil flows downwards in a film over baffles 90, and returns through the heat exchangers, to a filter 100. In a modification, the degasified oil is cooled before the final filtration by passing water through the heat exchanger 40, the contaminated oil being byepassed to the second heat exchanger 44.  A suitable construction oil is freed from suspended carbon in a filter 4, and is then forced by a pump 30 through a pipe 32 to a series of heat exchangers 40, 44, 46, 48 and into a vessel 50 containing a heating coil 51.  The oil is heated to a temperature of about 150 DEG F. and is then forced under pressure through a pipe 54 and through spray nozzles 60 mounted in a vacuum chamber 55.  The oil spray impinges on a series of baffles 70 releasing of the first filler, Fig. 2, consists of a pile of perforated discs 5, Fig. 3, and spacers 7 mounted alternately on a central hexagonal post having a handle 11. Opposite each spacer 7 is a cleaner 8 mounted on a non-rotatable post.  Oil is delivered through an opening 20 and passes downwards through the holes 6 in the discs to an outlet 21.

Title: Improvements in or relating to devices for winding and unwinding strips, ropes or the like
IPC: B65H18/10
Filed: 1938-01-31
Abstract: 508,595. Winding and paying-out apparatus. ARGENTO, R. Jan. 31, 1938, No. 3031. Convention date, Jan. 30, 1937. [Class 78 (v)] [Also in Groups XVIII and XVI] A brake device for maintaining tension in a band, rope, &c. wound on a roller or drum, comprises an elastic flexible endless belt 32 passing over pulleys 30 and 51, of which the pulley 30 is fixed on the roller shaft 40 and the pulley 51 on a parallel shaft 41. The shafts 40 and 41 are geared together by pinions 33 and 52 so as to rotate in opposite directions, thus causing constant slip, during winding or unwinding of the band &c. 6, between the belt 32 and the pulleys 30, 51, with a residual tension in the belt 32, on stoppage of the action, which keeps the band &c. 6 taut. Fig. 2 shows the application of the brake to two rollers 4, 5 from one to the other of which the band 6 passes round rolls 7, 8. Ratchetwheels 9, 10 on the drum shafts 2, 3 engaged by pawls 11, 12 prevent the band 6 from being drawn off either roller, but the pawls are carried by pivoted, spring-retracted arms 15, 14 respectively, one of which can be pulled aside at a time to free the corresponding roller. The means for pulling aside the pawls consists of a plate 22 sliding in guides 23 and held at each end by a tension spring 47, 48. An elongated slot 25 takes over pins 28, 29 projecting from the arms 14, 15 respectively, so that when a key is placed in the slot 25 and moved laterally till it comes over the shaft 2 or the shaft 3, the edge 49 or the edge 50 of the slot 25 respectively strikes the pin 28 or 29 to release the pawl and allow of winding. The roller shaft which is not being wound is covered by a blank part of the plate 22, but when the key is removed and the plate slides back into medial position openings 37, 39 in the plate 22 come over the shaft ends to permit the key to be applied to either one to tauten up the band 6 if necessary. As with the single roller, an elastic endless belt 32 takes over pulleys 30, 31 on the roller shafts to effect the braking.

Abstract: 948,875. Remote control of cathode ray tubes by photo-resistive elements. SIEMENS & HALSKE A G. Jan. 30,1962, No. 3486/62. Heading G1A. Also in Division H4] The invention relates to an electron beam source having a cathode and a control electrode, the electron beam from which is controlled by a remote beam of radiation impinging on a photoresistive element, so connected in the supply to the cathode of the electron beam source as to vary the positive potential of the cathode with respect to the potential of the control electrode of the electron beam source. As shown, the positive potential of a cathode K of an electron beam source, with respect to a control electrode S is varied by the change in resistance of a photoresistive element W1 such as a cadmium sulphide resistor, when the intensity of a radiation beam b impinging on the element W1 is varied. The beam b which originates from a source L may be varied by a potentiometer W2 connected across a voltage UL, by grey filters F or other colour filters, or by a continuously adjustable screen B. These measures for varying the intensity or colour of the beam b may be used in combination as shown. The photoresistive element W1 may comprise a single element or a plurality of elements in series, in which case the elements may be controlled by a single radiation source or each may be provided with its own source.
