Abstract: The invention comprises 3-aryl-4-R1-N-R-sydnonimines unsubstituted in the 3-aryl group in which R represents an alkanoyl group containing more than 2 carbon atoms or an alkylcarbamyl group, and R1 represents a hydrogen atom, an alkyl group, a halogen atom or an aryl group which is unsubstituted or is substituted by one or more substituents selected from C1- 6-alkyl, C1- 6-alkoxy, hydroxy, methylenedioxy or tri fluoromethyl groups or halogen atoms; their preparation by reacting a corresponding 3-aryl-sydnonimine with a functional acid derivative of an appropriate carboxylic acid and, if desired, halogenating a resulting compound and/or if desired, converting a free base into a salt or a salt into a free base; and pharmaceutical compositions containing them.  The alkanoyl group R may also be substituted e.g. by halogen atoms or by oxo group and may therefore include the a -halopropionyl and acetoacetyl groups.  3-Phenyl -4- (para-chlorophenyl)-sydnonimine is prepared by reacting para-chlorobenzaldehyde with aniline and potassium cyanide to form a -anilino -a - (para-chlorophenyl)-acetonitrile, nitrosating this to yield N-nitroso a -anilino -a - (para-chlorophenyl)-acetonitrile and treating this with methanolic hydrochloric acid.  Pharmaceutical compositions comprise the compounds of the invention in admixture or in conjunction with a pharmaceutically suitable carrier. The compositions may be in the form of tablets, dragees, ointments, creams, capsules, solutions, suspensions or emulsions and may contain other therapeutically useful substances. The compounds show analgesic, antipyretic, antiphlogistic and antiallergic properties and are useful as antirheumatics.

Title: Improvements in or relating to electrostatic printing processes
IPC: G03G5/02
Filed: 1964-05-29
Abstract: 1,030,383. Electrophotographic processes. CONTINENTAL CAN CO., Inc. May 29, 1964  [Dec. 4, 1963], No. 22422/64. Addition to 1, 020, 836. Heading G2H. An improvement in or modification of the method described and claimed in the parent Specification, includes establishing a potential difference between printing plate 40, Fig. 6, and a development electrode 70 during the application of image forming material 55, the electrode having the same polarity as the non-image areas of the plate, but being maintained at less electrical potential. A printing plate 41, Fig. 1, was etched, such that depressions 42 were formed at non-image areas, the unetched portions 43 providing image areas. The depressions 42 were filled with insulating material 44, Fig. 2 (not shown), e.g., epoxy resin, and the plate ground and polished to a smooth surface Fig. 3 (not shown). The plate was negatively electrostatically charged by moving conductor 51, Fig. 5, (not shown), in the form of fine steel or platinum wires across the plate surface by an insulated traveller 52. Non-image areas 46 become negatively charged, while exposed image areas 45 are positively charged. Developing powder 55, Fig. 6, is caused to cascade from a hopper 56, between the plate 41 and the development electrode 70. The powder has negatively charged toner particles which collect at areas 57 above the image areas 45. Insulating spacers 61, Fig. 7, (not shown), are placed upon plate 4D to receive layer 62 to be printed. The charge on plate 41 is then reversed in polarity, such that areas 45 become repulsive to toner particles. A conductor 63 connected to a high voltage source 65 is moved over the layer 62 by an insulated traveller 64. The layer 62 is thus given a positive charge which attracts toner particles at areas 57. [Instead of connecting the electrode 70 to a power source 71, the electrode 70 may have a dielectric coating and be subjected to a corona discharge]. The electric field established prevents toner adhering to areas 46.

Abstract: 668,808. Distilling oil shale. CALIFORNIA RESEARCH CORPORATION. Sept. 14, 1950 [Sept. 17, 1949], No. 22628/50. Class 55 (i). The gases and vapours evolved from oil shale which is distilled by contact with hot gas previously recovered from the shale, are cooled by direct counter-current contact with the incoming fresh shale, the normally liquid constituents condensing out and being withdrawn separately from the gases, which are heated and returned to the distillation zone. In the apparatus shown in the Figure the shale is fed from a line 1 to the lower end of a conveyer-condenser 3, which consists of an inclined tube opening at its upper end into a retort 4 and containing a conveyer chain 5 which carries the fresh shale to the feed-pipe 8 of the retort. Hot recycled shale gas enters the retort through a line 9, and distils the shale therein at about 1000‹ F. The distillation vapours and gases pass out through pipe 8 into the condenser 3, the condensed oils being withdrawn through a line 21 and fixed gases through a line 22. The spent shale passes from retort 4 into a kiln 12 where it is in part burnt by air entering through a line 13, the combustion gases passing out through line 14. The shale, heated to about 1220‹ F., passes down into a cooler 17, cool recycle gas entering through a line 18 and leaving through line 9, to enter the retort at about 1050‹ F. Spent cooled shale is withdrawn from the cooler through line 19. The gases from the condenser 3 pass through a second condenser 23 and gas-liquid separator 24 to a pump 27 which discharges product gas through a line 28 and recycle gas through the line 18. In a modification, Fig. 3 (not shown), the fines are screened from the fresh shale and passed into the retort, kiln and cooler entrained in the entering gases to form a fluidized bed above the mass of coarse particles, which pass through the plant as described above. In a further modification the kiln 17 is omitted, the gases to the retort being heated by partial combustion in an external combustion chamber, Fig. 4 (not shown).
