Title: Profile recognition method and apparatus for identifying bacteria
IPC: C12Q1/04
Filed: 1974-04-02
Abstract: 1472961 Microbiological testing ANALYTAB PRODUCTS Inc 2 April 1974 [10 April 1973 21 March 1974] 14599/74 Heading C6F A profile recognition method of identifying a bacterial specimen involves, in broad outline, performing a series of standard tests in a series of micro-reaction chambers 17, Figs. 1 to 3, mounted on a test plate 11, 21 tests made in 20 chambers, dividing the tests into seven groups of three, allotting to each group a score ranging from 0 to 7 in the following manner:  and comparing the seven - digit number obtained with a pre-prepared profile register. Example: 5 044 552 = E. coli. The coder depicted in Figs. 4 and 5 may be used to record the scores. In operation, whenever a positive reaction is to be recorded a pencil, probe or stylus 24 is inserted into an indentation 23a in the slide 23 of the group concerned through the appropriately positioned slot 25, 26 and 27, and the slide is then drawn out by the pencil &c. as far as the slot will allow. In this position the total score for the particular group is visible on the slide through window 28. For verification of the score, the simulated colour patterns on the slides visible through windows 29 can be matched with those obtained on the test strip 11. Aerobic and anaerobic bacteria may be tested. In a further embodiment employing 50 tests e.g. systems designed to determine Enterobacteriaceae or species and strains of Lactobacillus, the scores for each group may be represented by letters or numbers derived from a directory or coder, Fig. 8 (not shown). Example, CB 473 9UA GA = Streptococcus. This coder has five slides representing groups and has slot lengths in the ratio 1:2:4:8:16 per group giving 25 test positions. The other set of five groups is scored by using the coder a second time.

Title: Process for the production of ammonium nitrate
IPC: C01C1/18
Filed: 1931-05-22
Abstract: <PICT:0367660/III/1> The reaction between ammonia and nitric acid for the production of ammonium nitrate is carried out at a pressure above that at which the ammonium nitrate solution obtained would boil at the temperature developed in the reaction.  The heat developed in the reaction may be utilized to concentrate the ammonium nitrate solution in another vessel.  The ammonia is preferably employed in slight excess.  Nitric acid and gaseous ammonia are pumped by pumps A, B respectively through preheating coils D, C into a reaction chamber E where the temperature rises to 170-180 DEG  C.  The pressure in the reaction chamber is maintained constant by an automatic valve F through which the ammonium nitrate solution continuously discharges into an outer vessel G which is at or below atmospheric pressure. The heat of the reaction chamber causes the solution to boil and a concentrated solution passes off continuously through a pipe H while the developed steam passes through a pipe I and rectifying column M and heats the coils C, D. The steam is condensed ammonia free and leaves through a siphon N while the ammonia content of the steam leaves through a pipe P and is returned to the process.

Abstract: 218,645. Metropolitan-Vickers Electrical Co., Ltd., (Assignees of Keene, A. D.). July 6, 1923, [Convention date]. Sleeve couplings.-A connector for electric conductors comprises a tubular casing containing a member which expands permanently upon the application of heat and so fixes the conductors in the casing. The invention is described as applied to non- oxidizable conductors such as nichrome furnace resistors in which the heating elements themselves supply the heat to complete their couplings. A non-oxidizable. sleeve 28 of nichrome tightly encloses a tube 29 of oxidizable material such as iron or steel within which latter the ends of the resistor conductors 23 have a sliding fit. The crystalline character of the iron or steel is changed on heating and oxidization is set up both causing swelling of the tube and a tight joint. The iron &c. tube mav have radial holes 32 enclosing a mixture oi iron filings and sal-ammonic or lead oxide which expedites the action and assists the oxidation of the iron tube. Modifications are described comprising (1) an outer sleeve with divided, screwed ends having screw caps, (2) rectangular section sleeves for flat conductors with a bar of iron between them, and (3) forms in which a rod or bar is inserted into the recessed or slotted ends of conductors in a sleeve.

Patent GB-722843-A (GB)
Title: Manufacture of nitriles
Inventor: MILNE JOHN NOEL
Filed: 1952-06-19
Abstract: Nitriles are produced by reacting together an organic nitrile with a carboxylic acid, said nitrile, said carboxylic acid and the carboxylic acid corresponding to said organic nitrile having a higher boiling point than the nitrile which it is desired to produce, at an elevated temperature and distilling from the reaction mixture the nitrile corresponding to the acid employed. The reaction mixture is preferably heated at or near its boiling point, for example by refluxing, and the lower boiling nitrile thus formed is subsequently fractionated off.  The reaction may be effected at atmospheric pressure, but where the boiling point of the nitrile lies outside the range of 100-200 DEG  C., reduced or increased pressure is desirable. It is preferred to use an acidic catalyst such as p-toluene sulphonic acid, sulphuric acid, phosphoric acid or hydrochloric acid.  The starting materials may be aliphatic or aromatic, saturated or unsaturated.  Suitable initial nitriles include phenylacetonitrile, benzonitrile, propionitrile, caprioc nitrile, caprylic nitrile, and capric nitrile.  Suitable carboxylic acids include acetic, propionic, caprylic, crotonic, caproic, capric, phenylacetic and benzoic acids. In examples, (1) phenylacetonitrile and propionic acid were refluxed with p-toluene sulphonic acid as catalyst to produce propionitrile; (2) caprylic acid and phenylacetonitrile gave caprylonitrile; (3) crotonic acid refluxed with phenylacetonitrile gave crotononitrile; (4) benzonitrile and butyric acid were refluxed to give butyronitrile; and (5) phenylacetonitrile and benzoic acid gave benzonitrile.

Title: Improvements in or relating to fluid-operated clutch and like mechanisms

Filed: 1942-11-03
Abstract: 561,159. Clutch actuating mechanism. ABBEY, A. (Bliss Co., E. W.) Nov. 3, 1942, No. 15490. [Class 80 (ii)] [Also in Group XXIX] In a fluid-pressure system for actuating a clutch and brake mechanism, the fluid pressure is built up in two stages, the first stage by an electric motor which stalls at a predetermined fluid pressure and is then held in that' position by an electric brake, and the second stage by the driven machine. A driven shaft 20 is clutched by friction plates 28, 30, 47, to a driving pulley 22 when fluid pressure is built up in cylinders 35, and is frictionally connected to a fixed brake member 55 when the fluid pressure in the cylinders 35 is reduced. A combined electric motor and brake 60, 62, of known type is connected by gearing 65, 66, to a shaft 67 having a cam 71 co-operating with a plunger 73 in a cylinder 74 connected by piping 80, 82, to the clutch cylinders 35. A cam 87 on a shaft 85 geared to the driven shaft-20 co-operates with a follower roller 88 on a two-part piston 90, 91. The two parts of the piston 90, 91, are interconnected by a bolt 92 and are pressed apart by a compression spring 95, the small end 96 of the part 91 working in a cylinder 97 connected by piping 98 to the pipe line 82. The electric motor 60 and brake 62 are wired to a threephase source of power as shown in Fig. 5. Forward and reverse switches 117, 118, have relays 117<1>, 118<1>. Switches 125, 125<1>, which may be controlled by the cam 87 are included to give automatic declutching. In operation, depression of a switch 120 energizes relay 117<1> to close switch 117 and energize motor 60 and release brake 62. Motor 62 rotates cam 71 to depress plunger 73 and produce fluid pressure in the piping 80, 82. When a predetermined fluid pressure, sufficient to give initial clutch engagement, is attained, the motor 60 stalls, the switch 120 is then released, and the brake 62 holds the motor in the clutch engaged position. Rotation of the cam 87 thereupon operates the piston 90, 91, to increase the fluid pressure in the pipe 82 to giye full clutch engagement. The spring 95 is calibrated to yield above a predetermined maximum fluid pressure. When the driven machine has made its working stroke the cam 87 opens switch 125 and closes switch 125<1>, thus throwing in the reversing switch 118, whereupon the motor 60 reverses and the plunger 73 moves upwardly and lowers the fluid pressure in the clutch cylinders 35 to cause clutch disengagement. If a, line switch 127 is open continuous clutch engagement results. Release of the clutch may also be effected by closing a switch 121.
