Title: Improvements in the refining of acrylonitrile
Filed: 1957-09-23
Abstract: <PICT:0860686/III/1> Acrylonitrile contaminated with divinylacetylene is purified by vaporizing substantially anhydrous contaminated acrylonitrile under distillation conditions while countercurrently contacting the vapours with water so as to repress distillation of the major portion of the acrylonitrile while permitting distillation of the divinylacetylene, the residue comprising an aqueous solution of acrylonitrile substantially free from divinylacetylene, and recovering acrylonitrile from the residue.  Preferably the distillate is condensed and mixed with additional water to form two layers, one being an aqueous solution of acrylonitrile contaminated with a minor amount of divinylacetylene and the other predominantly divinylacetylene.  The acrylonitrile is subsequently removed from the aqueous residue by distillation.  In a preferred embodiment (Example 1) 80 grams of acrylonitrile contaminated with 1.5% of divinyl acetylene, and 2000 grams of water is fed into the middle of the extraction still column 11.  The distillate comprising 14.7 grams of water and acrylonitrile with 1.28 grams of divinylacetylene is led to a condenser 20 and additional water added.  After passing to a decanter 23 and allowing to settle, the lower layer containing acrylonitrile and water with a trace of divinylacetylene is returned to the extraction still.  The product from the kettle 15 passes to a stripping still 16 and gives rise to 60 grams of acrylonitrile containing less than 0.1 part per million of divinylacetylene.

Title: Recording apparatus combined with gas meter
IPC: G01F15/07
Filed: 1935-10-29
Abstract: 464,445. Recording - apparatus. GLOVER & CO., Ltd., T., and WILSON, J. S. Oct. 29, 1935, Nos. 29827/35 and 2683/36. [Class 106 (iv)] Recording-apparatus combined with a gas meter comprises meter-driven means for advancing a record strip and a clock-driven punch or other marker which marks the strip at a time or times determined by the setting of a member on a clock-driven dial. In a modification, the punch is also moved slowly by clockwork laterally across the record strip. An arm 23, Fig. 1, is rotated about its axis 21a by the gas-meter mechanism and is connected by gearing 21, 19, to a shaft 2 carrying two discs 2a having teeth which engage perforations in the paper strip and thus feed it from a supply roll 3a to a take-up roll 4a. The take-up roll 4a is driven from the shaft 2 through gearing including a slipping coupling. The rolls 3a, 4a are mounted in slots 1b and held by catches 1c so that they can readily be removed. Clockwork mechanism 25, Fig. 3, causes a disc 25a to rotate once in twenty-four hours. A trip member 28, Fig. 1, is settable on the disc 25a so that at any predetermined time it engages the end 26d, Fig. 6, of a lever 26 and swings the lever clockwise to release a pin 30a on a pinion 30 gearing with a pinion 29a on a shaft 29 which is then driven through one revolution by the clock spring. A cam 2 thus oscillates the depending end 33, Fig. 3, of a lever 31 to depress a punch.36 against the action of a spring 37 to punch the paper strip. In the modification, Figs. 9 and 10 the shaft 2 is similarly driven from the meter mechanism and carries a drum 2d having teeth 2b which feed the paper strip from the supply roll 3a to the take-up roll 4a, the latter roll being driven from the shaft 2 by a spring belt 41. A shaft 47 is driven through one revolution at any predetermined moment by the means described in connection with the form shown in Figs. 1-6. A long cam 47a is mounted on the shaft 47 and thus actuates the punch 36. The punch is mounted in a carriage 51 supported on shafts 48, 49, the former 48 of which is screwed to engage a nut in the carriage and is driven from the clockdriven disc 25b through a spring coupling 50a. The punch is thus slowly moved across the paper strip to produce a record as shown in Fig. 14. The carriage is adjusted to any desired position by a hand wheel 48a on the end of the shaft 48.

Abstract: 904,730. Automatic control systems for lathes. RUDIGER, F., [trading as WOHLENBERG KOMM.-GES., H.]. Sept. 1, 1960 [Sept. 11, 1959], No. 30111/60. Class 38 (4). Devices located on opposite sides of work being turned in a lathe measure, without contact, the distances away of the surface just cut, and the difference between the actual diameter computed from these measurements and a desired diameter, is effective to correct the position of the tool automatically. As shown, deviations in the diameter of work 5 are detected by two air jets directed on to opposite sides of the work by nozzles 2 and 3. The resultant pressure in the two conduits leading to the nozzles is applied to a pressure gauge 6 so that deviations exceeding a predetermined value in either sense from a desired value actuate contacts 7 or 8 to operate a motor 12 in a corresponding sense to correct the deviation by adjusting, through reduction gearing 16, the position of the tool holder 17 relative to its slide 15 and hence relative to the work. A removable coupling is provided between motor 12 and tool holder 17 so that the latter can be adjusted manually with the aid of dial gauge 23. The motor-tool holder assembly is readily removable for replacement. An accurately turned portion of the work 25 in conjunction with micrometers 26, 27 serve for setting the desired diameter of the work.

Abstract: 723,082. Exchange systems; party-line systems. SIEMENS BROS. & CO., Ltd. Nov. 27, 1953 [Nov. 28, 1952], No. 30257/52. Class 40(4). The ringing circuit at each substation comprises a rectifier PR and a cold cathode gas discharge tube PT in series with a polarized A.C. bell PB and a condenser PQ, the bell and condenser being shunted by a resistance PO. Two such ringing circuits with oppositely poled rectifiers and tubes are connected between each line wire and earth. The required substation is called by the application to the relevant line wire at the final selector of 17 c/s. alternating ringing potential superimposed upon a steady potential of the correct polarity, so that the tube PT becomes conductive only while the alternating and steady potentials are additive. During this period current flows through the bell PB in one direction to charge the condenser PQ which then discharges in the other direction through the bell PB during the remainder of the cycle. The bell thus receives the necessary alternating ringing current. At the final selector, the selection of positive or negative steady potential is controlled by a relay FS. In modifications, the tube PT and rectifier PR may be replaced by a tube having rectifying properties, and the bell may be connected to the secondary winding of a transformer having its primary winding in the ringing circuit.
