Filed: 1972-03-15
Abstract: 1387306 Derivatives of 3,4-diphenylpyrazolyl- 5-acetic acid SOC GENERALE DE RECHERCHES ET D'APPLICATIONS SCIENTIFIQUES 14 March 1973 [15 March 1972] 12182/72 Heading C2C The novel 3,4-diphenylpyrazolyl-5-acetic acid derivatives of general Formula I wherein R 1  and R 2  are independently phenyl groups optionally substituted by halogen, CF 3 , C 1-4  alkyl or C 1-4  alkoxy groups; R 3  is a straight or branched chain C 3-7  alkyl or alkenyl group or a phenyl or benzyl group which is optionally ring substituted by halogen, CF 3 , C 1-4  alkyl or C 1-4  alkoxy groups or by any two of these substituents; R 4  is H or C 1-4  alkyl and A is -CO 2 H, CO 2 R 5  or CONR 6 R 7  where R 5  is a C 1-4  alkyl or benzyl group and R 6  and R 7  are H or C 1-4  alkyl or R 6 -N-R 7  represents a pyrrolidino, piperidino or morpholino group, may be prepared by (a) hydrolysing a compound of Formula II  in which R 1 , R 2 , R 3  and R 4  are as above and Z is an ester, nitrile, amide or thioamide group or (b) decarboxylating a malenic acid derivative of general Formula III in which R 1 , R 2 , R 3  and R 4  are as defined above or (c) by reaction of a 1,2-diphenyl acetylene with a sydnone of Formula V wherein Y represents or -COCH 3 . Ethyl-N-benzylaminoacetate is prepared by reaction of benzylamine with ethyl bromoacetate and is further reacted with sodium nitrile and concentrated hydrochloric acid to form ethyl-N- nitrosobenzylaminoacetate which is, in turn, reduced with zinc and acetic acid to obtain ethyl-1-benzylhydrazinylacetate. Reaction of this product with benzil yields ethyl-α-benzylbenzylidene-N-benzoylhydrazinyl acetate which is cyclized on treatment with sodium ethylate to obtain ethyl-1-benzyl-3,4-diphenylpyrazole-5-carboxylate. Reduction of this carboxylate with LiACH 4  yields 1-benzyl-3,4-diphenyl-5-hydroxymethylpyrazole which is reacted with thionyl chloride to obtain 1-benzyl-3,4-diphenyl-5- chloromethylpyrazole which is in turn reacted with sodium cyanide to obtain 1-benzyl-3,4- diphenylpyrazole-5-acetonitrile. Using the same process steps 1-isobutyl-3,4- diphenylpyrazole-5-acetonitrile and 1-phenyl- 3,4-diphenylpyrazole-5-acetonitrile are prepared respectively from isobutylamine and aniline. Methyl-N-isobutyl-#-aspartate is prepared by reacting monomethyl maleate with isobutylamine and is then reacted with sodium nitrite and conc. hydrochloric acid to obtain methyl-N- isobutyl-N-nitroso-#-aspartate which is reacted with perchloric acid to obtain methyl-3-isobutyl- 4-sydnonyl acetate. α - [1 - Benzoyl - 3,4 - diphenylpyrazolyl - 5]- propionitrile is prepared by reacting 1-benzyl- 3,4 - diphenylpyrazolyl - 5 - acetonitrile with methyl iodide in the presence of NaNH 2 . Pharmaceutical compositions having antiinflammatory and antipyretic activity for oral or rectal administration comprise a compound of Formula I optionally together with a pharmaceutical adjuvant and standard pharmaceutical media and diluents.

Title: Method of and means for supervising the filling level in hoppers shafts silos and the like containers for miscellaneous materials
IPC: G01F23/00
Filed: 1974-03-20
Abstract: 1455592 Detecting the level of a fluent  material ASER AB 20 March 1974 [21 March 1973] 12321/74 Heading G1G The Specification describes a method of supervising the filling level in various containing vessels, e.g. a mine shaft, for miscellaneous materials e.g. crushed mineral products wherein the filling level is detected by the action of the moving material against various probes mounted in the container, the vibrations induced in which are converted into level indicating signals. In Fig. 1, shaft 10 has a curved bottom portion 11 communicating with an unloading zone 12 via pivotable hatch 15 operated by hydraulic or pneumatic motor 16. A transport truck 18 is filled through the open hatch 15. Metal rods 22, 23, of e.g. steel, passed through and mounted in holes 20, 21 drilled between zone 12 and shaft 10, are secured at their upper ends 27 by cement and transmit vibrations from moving material in the shaft 10, to microphones or accelerometers 27, 28 respectively. Material poured in through openings 14 gradually fills up shaft 10 and the detected vibrations are amplified by amplifiers 29, 30 which drive lamps 31, 32 in such a way that each of lamps 31 and 32 is illuminated when the level of the material falls below the rod end 24 or 25 respectively, thus giving an indication of the material level in the shaft. In other embodiments, the lamps are replaced by pointers, recorders, acoustic arrangements or the like. In another embodiment, Fig. 3 (not shown), amplifiers 29 and 30 are connected to a magnetic valve (33) which regulates the supply of working medium to the motor 16. The hatch 15 is operated to fill a truck only when the falling material striking the rod end 24, and causing extremely strong vibrations, ceases, thus indicating that the level of material is above rod end 24.

Title: Improvements in and relating to apparatus for Intermittent Feed of Strip Material
Inventor: THARRATT HARRY
IPC: B65H23/192
Filed: 1968-03-15
Abstract: 1,196,355. Rotary machines. NORPRINT Ltd. 5 Feb., 1969 [15 March, 1968 (3)], Nos. 12819/68, 12820/68 and 12821/68. Heading B6C. [Also in Division B8] Apparatus for intermittently feeding strip material includes means for driving the strip forward at a first speed to beyond a desired position and backward at a second speed, lower than the first, to the desired position, whereby accurate registration of the strip is achieved. As shown, a strip 13 consisting of labels 37 separated by perforations 38 is fed by a friction roller 11 to a printing arrangement comprising a pair of drums 28 which are geared to rotate together and which have raised parts 29 carrying printing type, the drums co-operating with impression cylinders 30. The roller 11 is driven by an electric motor through interposed gearing associated with two electromagnetic clutches and an electromagnetic brake (Fig. 1, not shown) controlled by known circuitry in response to signals derived from photo-electric devices 36, 33. In operation, the strip 13 is driven forward at a relatively high speed until the photo-electric device 36 detects a perforation 38 and produces a signal to stop the forward drive and initiate a slower, reverse, drive; owing to the high forward speed initial overshoot is inevitable so that the label 37 to be printed moves beyond its desired position. The necessary backward drive therefore takes place at a much slower speed, and when the photo-electric device 36 again detects the already sensed perforation 38 the resulting second signal is utilized to stop the feed. With the label in its desired position the drums 28 rotate to effect the printing and when this has been done a signal from the photo-electric device 33. associated with the drums 29, causes the feeding cycle to recommence. Sensing of the forward movement of the strip 13 may be dispensed with, the roller 11 then being arranged to drive the strip forward through a known distance; sensors of the magnetic or capacitive type may replace the photo-electric devices 33, 36, or the device 33 may be replaced by electric contacts.
