Title: Improvements in or relating to the production of aliphatic dinitriles
IPC: C07C51/34
Filed: 1960-09-30
Abstract: Aliphatic dinitriles are obtained by azonizing at 10 DEG -50 DEG C., unsaturated fatty acids, nitriles or amides while dissolved in an aliphatic nitrile, decomposing the ozonide, oxidizing the product to a mixture of acids, nitrilizing the mixture without separation to produce a mixture comprising an aliphatic mono- and di-nitrile and separating the dinitrile. The nitrile solvent may be the aliphatic mono nitrile produced in the nitrilizing reaction. The ozonides are decomposed with the aid of phosphorus containing acids, anhydrides and esters (listed) while both the oxidizing and nitrilizing reactions are aided by catalysts which are specified. Oleic, linoleic, tall oil and rice bran fatty acids are specified starting materials, and, in an example, azelaonitrile with minor amounts of malonitrile, capronitrile and pelargonitrile are obtained. Specification 757,355 is referred to.

Title: Antigen for the treatment of foot and mouth disease
IPC: A61K39/135
Filed: 1937-12-09
Abstract: 505,859. Foot and mouth disease antigen. CROFTON, W. M. Dec. 9, 1937, No. 34090. Drawings to Specification. [Class 81 (i)] Antigen for the treatment of foot and mouth disease is prepared from a culture of the foot and mouth bacillus, a minute non-motile gramnegative bacillus which can be cultured from specimens of the blood or urine, lesions or other parts of an infected animal and grows on agar medium containing blood of a susceptible animal and also on ordinary broth and ordinary agar. When plated out it, grows confluently along the stroke of the needle ; the colonies when growing separately are round and grey. The cultures have the odour of an animal suffering from the disease In obtaining the antigen a specimen may be cultured on a medium comprising extract of fresh bullocks heart, peptone and salt to which about 25 per cent of agar is preferably added and also about 10 per cent of de-fibrinated blood from a healthy animal. The culture after incubation for 24 hours or less at body temperature may be sufficiently pure, but if not it may be subcultured one or more times under the same conditions. If cultures so obtained are incubated in unheated defibrinated blood medium the bacillus is stated to pass into virus form. By filtering the virus through a Seitz filter it can be obtained in pure form and by the incubation for 24 hours or more of the clear filtrate stained with haemoglobin the bacillus form is again obtained in pure state. For injection into an animal for curative or preventive purposes, the culture may be used but the bacillus is preferably killed, e.g. chemically, by means of formol saline or phenol saline or by heating to a temperature not exceeding 55‹ C.

Title: Method of and apparatus for bending and tempering glass sheets
Inventor: CARSON FRANK JACOB
IPC: C03B27/044
Filed: 1964-08-21
Abstract: <PICT:1071555/C1/1> <PICT:1071555/C1/2> Glass sheets are bent and tempered by heating to softening point, then establishing different temperatures on opposite surfaces, and finally chilling rapidly to cause warping.  The sheet is fed on rollers 21 through a furnace 10 heated by burners 22, 23, heating of the upper surface being to a higher temperature than the under-surface to cause bowing.  The rollers at the exit side of the furnace run at a greater speed and feed the sheet to the primary cooling section 11 where pairs of elongated nozzles 26, 27 direct cooling air on to the upper surface of the ends of the sheet, causing slight upward bending of the ends which is subsequently eliminated.  The sheet then passes between blower heads 32, 33 directing streams of cooling air from nozzles or slots 37 across the sheet, the pressure and the volume from the upper head being greater than from the lower so causing differential cooling and bowing.  The last few of the conveying rollers in the section are under the control of a photo-electric cell 41 or like device which slows them down before delivering the sheet to the final cooling sections, and then returns them to their former speed.

Abstract: 1,214,754. Endless conveyers. SERVICE D'EXPLOITATION INDUSTRIELLE DES TABACS ET DES ALLUMETTES. 8 July, 1969 [10 July, 1968], No. 34285/69. Heading B8A. In apparatus for transferring matchbox drawers B from an endless chain conveyer C to a conveyer T, if the conveyer T is unable to receive the drawers, the latter, being subjected to longitudinal compression, curve upwardly and cause the conveyers to be de-energized. A trough 11 for the drawers is pivoted at 13, 14 and, at its other end, is supported by a U-shaped spring 16 which frictionally engages two jaws adjustably mounted on a frame member 17a. A rod 22 of inverted T-section has a tapered portion 19 which causes the drawers to be released from the conveyer C and deposited in the trough 11. When there is upward movement of the drawers and engagement with the rod 22, the resulting pressure causes the non-pivoted end of the trough 11 to drop and a switch 23 to de-energize the conveyers. A signal may also be emitted. The drawers in the trough having been discharged and the downstream fault cleared, the trough is returned to its normal raised position by a handle 18. Excess matches are removed by the rod portion 19 and are recovered by a suction device.

Title: ª‡-chloroglutaric anhydride
IPC: C07C55/32
Filed: 1957-11-04
Abstract: The invention comprises a -chloro-glutaric anhydride.  The compound may be prepared by reacting chlorine and glutaric anhydride at a temperature between 75 DEG  and 160 DEG  C.  When lower reaction temperatures are used a phosphorus, or phosphorus halide, oxyhalide, oxy acid or oxide catalyst may be advantageously employed.  In the examples: (1) chlorine is bubbled into molten glutaric anhydride at 105-115 DEG  C. until the theoretical amount of chlorine has been absorbed, similar results are obtained chlorinating at 110-160 DEG C.; (2) glutaric anhydride is chlorinated at 80-95 DEG  C. in the presence of about 7 per cent of phosphorus trichloride.  a -Chloro-glutaric anhydride may be converted to DL-glutamic acid on treatment with aqueous ammonia at 250 DEG  C. for 9 hours.
