Abstract: 1469545 Automatic control systems; optimizing SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ BV 29 April 1974 [1 May 1973] 18571/74 Heading G3R In the control of a distillation process, a feed stream 2 being separated into top and bottom products 6, 8 a controlled parameter { e.g. yield of top or bottom product } is optimized, correcting parameters in the production process being successively controlled, possibly using a digital computer, with due allowance for their interdependence the ordering of the correcting parameters in the sequence being determined such that with the most substantial effect on the controlled parameter is first. Limiting values of the parameters are set, and the parameters are monitored to determine whether such limits have been attained. Means are provided to control as correcting parameters; the top product reflux, 19, 20; liquid level in accumulator 5:11, 12; heat input, by means of exchanger 9, to the bottom product reflux, 17, 18; liquid level in the bottom of the column, 13, 14; and heat input to the feed stream 2:15, 16. Meters are provided to measure as controlled parameters, the qualities of the top and bottom products; 21, 22, and the rectifying and stripping tray loads 24, 23. The interdependence of various parameters, and their absolute limit values are depicted in Fig. 2 (not shown). By means of sequential settings for values of correcting parameters, yield of top or bottom product for requisite quality can be obtained. Control is exercised by means of the heat supplied in the various streams, and the degree of circulation reflux, correcting physical properties including pressure and flow-rate. There may additionally be an intermediate product stream.

Filed: 1952-07-23
Abstract: Spoilage by micro-organisms, especially by the "flat-sour" organisms and heat-resisting, hydrogen sulphide- or poison-producing Clostridium spp., of substances intended for animal consumption is prevented by the incorporation of nisin. The nisin may be incorporated in admixture with an edible vehicle.ALSO:Spoilage of foods and beverages other than milk and cheese, e.g. vegetables, cereals, meat, fish, broths, stocks, pies, pastes and alcoholic potable liquids, by micro-organisms, especially the "flat-sour" organisms and heat-resisting, hydrogen sulphide or poison-producing Clostridium spp., is prevented by the incorporation of nisin.  Foods adversely affected by heat treatment, e.g. garden peas and sardine and tomato paste, may, after addition of nisin, be heated at 5-10 DEG F. lower than usual. The nisin may be incorporated in admixture with an edible vehicle, e.g. meat broth, milk curd, fish powder, tomato powder, wheat flour, cornflour, soya flour, arrowroot, rice powder, pea powder or cheese.

Title: Improvements in or relating to monitoring arrangements for telegraph systems
Inventor: STORR-BEST JOHN LLOYD
IPC: H04L27/16
Filed: 1949-07-15
Abstract: 662,709. Testing apparatus for telegraphy. STANDARD TELEPHONES & CABLES, Ltd. July 15,1949, No. 18688/49. Class 40 (iii). [Also in Group XL (c)] In a monitoring arrangement for frequency shift telegraphy, a device such as a cathode-ray tube is used for indicating the difference between the marking and spacing frequencies, the device being prevented from responding to both frequencies at the same time by means controlled by the telegraph signals. The oscillator 3 generating 200 kc. is controlled by the telegraph key 1 to give an increase of 0.7 kc. during spaces and a similar decrease during marks. The frequencies are raised by the mixer stage 4, 5 and radiated at 6. The output from the oscillator 3 is passed through a limiter 7 to a mixer 8 which is also fed by a source 9 generating about 195 kc. The beat frequencies (5 Œ 0.7 kc.) are passed through an amplifier 11 to the horizontal deflecting plates of a C.R. tube 12, the vertical plates of which are fed from a calibrated measuring oscillator 13 covering a range from 4 to 6 kc. For rendering the C.R. tube responsive to a selected one of the two frequencies, the key 1 is connected to the grid of one valve of a cathode-coupled pair 23, and the anodes are associated with a selector switch 31. During spacing periods the left-hand valve is conductive and the right-hand valve blocked, the condition being reversed during the marking period. With the switch 31 in the position shown, negative voltage pulses will be passed through the condenser 32, and across the diode 33 and resistor 18, to block the tube 12 at the grid 17 during spaces, and in the other position of the switch 31 the tube 12 will be blocked during marks. To measure the difference between the mark and space frequencies, the switch 31 is placed in a selected position, and the frequency of the oscillator 13 adjusted until the pattern on the screen indicates equality of that frequency with the frequency supplied from the mixer 8. The switch 31 is then thrown to its other position and the oscillator 13 adjusted until equality is again indicated. The difference between the marking and spacing frequencies is the difference between the two readings of the calibrated oscillator 13. Its accuracy is independent of changes in frequency of the oscillators 3 and 9. In order to check the accuracy of calibration of the measuring oscillator 13 at its centre frequency of 5 kc., a switch 10 may be thrown to connect a crystalcontrolled 10 kc. source 34 to the horizontal deflecting-plates, the screen pattern indicating when a true 2 to 1 relation exists between the frequencies. Switches 35, 36 may connect the measuring circuit to other signalling channels. The figures given for the several frequencies are by way of example only.

Class 83 (4) In a method of piercing billets 7, Fig. 1, by hot punching in a container 1, waste of billet metal is reduced by placing a wafer 10, Fig. 2, of less valuable metal at the base of the billet so that the metal of the expelled punching 9 is mainly that from the wafer 10. The punch 5 guided by a member 6 placed on top of the billet 7 is pushed nearly to the base of the billet by a ram 4 after which a central base portion 2a of the container is lowered on a support 3 to permit the punching 9 to be expelled. The wafer 10 may be attached to the billet as by welding and may be a flat plate or of varying thickness through its cross-section. It may be heated to a temperature lower than that of the billet. The wafer may remain on the end of billets to be extruded according to a known process in which a low priced metal is arranged at the back of a billet in the extrusion press.

Abstract: 533,012. Aminobenzoic acid alkamine esters. NOVOCOL CHEMICAL MFG. CO., Inc. July 1, 1939, No. 19217. Convention date, Nov. 5, 1938. Samples furnished. [Class 2 (iii)] Anaesthetic bases of the formula NH 2 .C 6 H 4 - COOCR<SP>1</SP>R<SP>2</SP>.CH 2 .NHR 3 , in which R<SP>1</SP> is an alkyl group, R<SP>2</SP> is hydrogen or an alkyl group and R<SP>3</SP> represents an alkyl group containing not more than five carbon atoms, are prepared by reacting a nitrobenzoyl halide with an aminoethanol of the formula HO.CR<SP>1</SP>R<SP>2</SP>.CH 2 .NHR<SP>3</SP>, and reducing the nitro product. Thus, mono-namylamino - α - dimethylethyl - p - aminobenzoate is prepared by re-acting p-nitrobenzoyl chloride with mono-n-amylamino-α-dimethylethanol in the presence of sodium hydroxide and reducing the resulting nitrobenzoic ester with tin and hydrocloric acid ; it is then converted into its sulphate. In a similar way may be prepared mono-n-butylamino-α-diethylethyl-paminobenzoate and the sulphates of mono-npropylamino-α-dimethylethyl-, mono-n-butylamino-α-dimethylethyl-, mono-isobutylamino- α-dimethylethyl-, mono-isoamylamino-oc-dimethylethyl- and mono-isobutylamino-α-diethylethyl-p-aminobenzoates. Samples have been furnished under Sect. 2 (5) of the sulphates of mono-isobutylamino-α- dimethylethyl-m-aminobenzoate, mono-isobutylamino-α-climethylethylo - aminobenzoate, mono - isobutylamino - α - methylethyl - oaminobenzoate, mono-isobutylamino-α-methylethyl-p-p-aminobenzoate and mono-n-amylamino - α - methylethyl - p - aminobenzoate, and the phosphate of mono-isobutylamino-α-methylethyl-m-aminobenzoate, all prepared by reducing the reaction of product of o-, m- or pnitrobenzoyl chloride with the appropriatelysubstituted amino-ethanol. The above substituted amino-ethanols are prepared by interaction of the appropriatelysubstituted α-chlorohydrin and the corresponding monoalkylamine. For example, mono-npropylamino-α-dimethylethanol is obtained by heating isobutylene-α-chlorhydrin in solution with n-propylamine. The α-chlorohydrins may be obtained by reacting a monochloracetic ester or an alkylchlormethylketone with an alkylmagnesium halide. Thus #-chlor-α-diethylethanol is prepared from ethylmagnesium bromide and ethyl monochloracetate or ethylmagnesium iodide and ethylchlormethylketone.
