Title: Automatic sampliing mechanisms
IPC: G01N1/00
Filed: 1974-05-01
Abstract: 1465678 Sampling apparatus for liquids SOCIAL SERVICES SECRETARY OF STATE FOR 1 May 1974 [17 April 1973] 18412/73 Heading B8N [Also in Division G1] An automatic sampling mechanism in which liquid in discrete quantities is introduced through a tube 26 into a receiver 14 or 14A, has a beam 30 pivoted to one end of a lever 40 and arranged when the lever pivots to engage an adjustable stop 62 and so bring the end portion of the tube into sidewise contact with an interior wall of a receiver for the period during which, in use, liquid is introduced therein, so that when the tube is withdrawn from the receiver substantially no droplet of liquid is on the outside of the tube. As described a ring of receivers, e.g. 14, 14A, is formed in a disc 16 surrounded by an annulus 12 containing vessels 10, 10A, and holes 24, 24A. The disc 16 and annulus 12 are mounted on a table 18 which is intermittently driven from a continuously driven shaft 56. The tube 26 and a further tube 28 are connected via tubes 32, 34 respectively to a dispensing/diluting device 36, and are carried at one end of the beam 30 pivoted at 38 to the lever 40 and spring urged clockwise to a position normal thereto. The lever 40 is pivoted to a rotatable column 46 and at its free end has a follower 52 engaged with both the face and edge of a cam 54 on the shaft 56. In operation, from a starting position in which the beam is in the positions 60, Fig. 2, and 30, Fig. 1, and the lever is in the position 40, rotation of the cam 54 causes the lever to pivot to position 40A thus lowering the beam and inserting the tube 26 into a vessel 10 and the tube 28 through a hole 24. A switch 74 then causes the device 36 to operate so that a sample of liquid is sucked from vessel 10 into tube 26. Further rotation of the cam raises beam 30, pivots it to position 60A, Fig. 2, and then again lowers it. During lowering of the tube-carrying end of the beam its free end 76 engages the adjustable stop 62 so that the tube end follows the path 78 and engages the sidewall of a receiver 14 as it enters therein. Tube 28 also contacts the side wall, the ends of the tubes 26, 28 being flexible to cater for this. Device 36 is then operated to discharge the liquid sample from the tube 26 into receiver 14 and also to supply a reagent via tube 28. The tubes are then raised and returned to their starting positions and the table 18 is indexed for a further cycle of operation. From the starting position the beam 30 may be swung to the position 60B to facilitate access to the table 18. Such swinging is effected by a handwheel 86, operation of which is prevented by interengaging locking means on the camshaft 56 and table shaft 20 when the beam is not in the starting position.

Title: New dikojyl aryl methanes
Inventor: SIMPSON THOMAS HARDY
IPC: C11B5/00
Filed: 1959-05-29
Abstract: The invention comprises dikojyl-aryl methanes of the general formula <FORM:0941113/C2/1> wherein R1is an aryl radical substituted by one or more hydroxy and/or alkoxy or aralkoxy groups and optionally by one or more alkyl groups and R2, which may be the same or different, is hydrogen or an alkyl group.  The compounds may be prepared by reacting one mole of an aromatic aldehyde R1CHO with two moles of kojic acid or a derivative thereof having the formula <FORM:0941113/C2/2> in the presence of a weak alkali e.g. NH4OH or KHCO3, as catalyst and if desired in the presence of a solvent, e.g. ethanol, R1 and R2 being as defined above, although where R1 represents an aryl radical containing one or more hydroxy groups, the latter one or more of them may be protected for example by benzylation and these protecting groups are removed after the reaction. The compounds may be used as anti-oxidants in oils, fats, methyl linoleate, linoleic acid and cod liver oil methyl esters. Examples describe the preparation of (1) dikojyl (o-hydroxy phenyl) methane; (2) dikojyl (p-hydroxy phenyl) methane; (3) dikojyl (2 - hydroxy - 5 - methoxyphenyl) methane; (4) di-(7-O-tert. butyl kojyl)(2-hydroxy-5-methoxyphenyl) methane; (5) dikojyl (2-hydroxy-5-benzyloxyphenyl) methane and its debenzylation by heating with acetic and hydrochloric acids; (6) di-(7-O-methyl kojyl)(2-hydroxy-5-ben-zyloxyphenyl) methane and its debenzylation by the method of (5); (7) dikojyl-(2-methoxy phenyl) methane; (8) dikojyl-(m-hydroxyphenyl) methane; (9) dikojyl (4 - hydroxy - 3 - methoxyphenyl) methane; (10) dikojyl-(3-hydroxy-4-methoxyphenyl) methane and (11) dikojyl (3:5-di-tert. butyl-4-hydroxyphenyl) methane.  Most of these compounds are isolated as hydrates and are converted into poly-acetic esters by reaction with acetic anhydride in the presence of pyridine and the acetates are recovered as crystals containing one mole of ethanol.ALSO:Oils, fats and other lipids are stabilized against oxidation by means of dikojyl aryl methanes having the general formula <FORM:0941113/C3/1> wherein R1 is a phenyl or other aryl radical substituted by one or more hydroxy and/or alkoxy or aralkoxy groups and optionally by one or more alkyl groups and each R2, which may be the same or different, is hydrogen or alkyl.

Title: Method of and apparatus for applying a hard alloy coating to the seating surfaces of valves for internal combustion engines
IPC: B22D19/08
Filed: 1953-07-22
Abstract: 743,582. Making valves for internal combustion engines. AUSTIN MOTOR CO., Ltd., and HIGHFIELD, F. W. W. July 22, 1953 [July 23, 1952], No. 18571/52. Classes 83 (2) and 83 (4). The seating surface of an internal combustion engine valve is coated with a hard alloy by applying the latter as a solid ring to the seating surface of the valve and then conveying the valve and ring, whilst they are being rotated, through a number of working stations on which are performed successively the steps of applying flux to the seating surface of the valve and the ring, preheating the valve and ring by electrical induction heating and finally heating the valve and ring by electrical high-frequency induction to cause melting of the ring and its fusion to the seating surface. The valves are placed head downwards in apertures 26 of a rotatable magazine 25 and a ring of cobalt-chromium alloy is placed on to the seating surface of each valve. The magazine is intermittently rotated to bring the valves successively into alignment with chucks 13, mounted on a carrier 11 which is rotated intermittently by an electric motor 14 through Geneva mechanism 15-17. When a valve is aligned with a chuck 13 at the loading station A, it is raised by a fluid pressure-operated plunger and the stem of the valve is gripped by the chuck; the latter is controlled by a fluidpressure cylinder. The chucks are rotated continuously about their own axes by an electric motor 18, through gearing 21-23. Intermittent rotation of the carrier 11 brings the valve to station B where the valve head and alloy ring are sprayed with oil from a container 42 the ring being raised from the seating surface during spraying. The valve then passes to station C where the seating surface and ring are sprayed with powdered flux after the ring has been raised from its seating. At station D the valve head and ring is heated slowly to a low temperature by a high-frequency induction coil, and at station E the main heating by high-frequency induction is effected whereby the alloy ring is melted and deposited as a coating on the seating surface. The head is shielded by a reducing gas, for example, acetylene, during the main heating. At station F the chuck 13 is opened, the valve is lowered and is then passed through a circular cooling chamber 83 provided with a revolving floor for conveying the valve therethrough. The chamber is heated electrically to avoid too rapid cooling of the valve.

Title: Improvements in or relating to the preparation of aldehydes of 1:2:3-substituted pyrazolones
Filed: 1950-07-27
Abstract: Aldehydes of the formula <FORM:0686614/IV (b)/1> where R is alkyl or aryl, R1 is aryl and R11 is alkyl, are obtained by the decomposition of quaternary salts of the formula <FORM:0686614/IV (b)/2> p  where R111 is aryl and X is halogen.  The decomposition may be effected (1) by boiling with aqueous caustic potash for 5 minutes or less, preferably 45-60 seconds; or (2) by treatment with aqueous potassium carbonate to give the Schiff's base of the desired aldehyde and hydrolysis of the latter with a stronger base (e.g. caustic soda) or with an acid (e.g. acetic), preferably for less than one minute.  The resulting aldehyde may be purified by conversion into a functional derivative and subsequent hydrolysis of the latter.  Suitable reagents for this purpose are hydroxylamine, semicarbazide, phenylhydrazine, nitrophenylhydrazine, dinitrophenylhydrazine and aminoguanidine. Hydroxylamine is preferred, the resulting oxime being hydrolysed with a mineral acid such as hydrochloric or a ketonic acid such as pyruvic.  The starting materials are made by reacting the appropriate 1 : 3-disubstituted-5-pyrazolone with a diarylformamidine or aryl isocyanide to give the Schiff's base of the 1 : 3-disubstituted-5-pyrazolone-4-aldehyde, and introducing the 2-substituent by means of an alkyl halide.  In the examples R is methyl or phenyl, R1 is phenyl or p-ethoxyphenyl, R11 is methyl and R111 is phenyl or p-ethoxyphenyl; (1)-(10) describe the preparation of the aldehydes by the two methods; (11)-(13) the isolation of oximes; (14), (15) and (17) phenylhydrazones; (16) nitrophenylhydrazone; (18) dinitrophenylhydrazone; example (22) shows the purification of the aldehyde as its bisulphite compound and regeneration from the latter; (23)-(26) the hydrolysis of oximes with hydrochloric or pyruvic acid; (27)-(30) the hydrolysis of semicarbazones with phthalic anhydride or with a mixture of acetic and pyruvic acids; and (31)-(33) the decomposition of phenylhydrazones with pyruvic acid or benzaldehyde, the phenylhydrazones of the latter being obtained as by-products.
