Title: Ultrasonic testing
IPC: G01N29/04
Filed: 1973-01-12
Abstract: 1422441 Ultrasonic testing MATERIALS & METHODS Ltd 31 Dec 1973 [12 Jan 1973] 1792/73 Heading H4D The velocity of sound in a solid specimen is measured, e.g. to test the quality of a metal casting subject to thickness variation, by comparing the time taken for an ultrasonic signal to pass through the thickness of the specimen with a standard time value which is varied in proportion to the local thickness as measured in the path of the ultrasonic signal. In the Fig. 1 embodiment the specimen is supported by table 2 and an echo pulse from its back wall, obtained from probe 1, is displayed within a time gate marker on a CRO time-base. A sensor 5 incorporating a rotary or slider potentiometer is brought down on to the specimen to gauge its thickness. The sensor output positions the time gate at a point corresponding to an acceptable reference sound velocity. The echo from an acceptable test specimen should thus be within the gate, irrespective of specimen thickness. Lamps may also give a "go-no go" indication of the test result, In the Fig. 2 embodiment the specimen is held in a sliding caliper, one arm of which includes an ultrasonic probe 25. A grip 24 to to close the caliper also operates a potentiometer to control the time gate position as above.

Title: Improvements in variable condensers for use in connection with wireless telephony and telegraphy
IPC: H01G5/06
Filed: 1925-01-26
Abstract: 247,365. Collingburn, J. B. Jan. 26, 1925. Condensers of the variable type comprise a series of fixed plates and a series of movable plates capable of being moved entirely into and out of mesh with the fixed plates by movement relatively to each other. The relative movement may be effected by toothed, worm or like gearing or operating mechanism and the moving plates may be half-round, rectangular or other shape suitable for a square-law relationship. The movable plates a are mounted on a shaft b<1> between washers h and, if desired, spring tongues for obviating loose working. The plates have toothed segments g adapted for engaging a ribbed sleeve d carrying an operating knob e and index plate f. The end plates a<1>, a<2> have longer segments so that a<1> is not disengaged from the sleeve d in the all-in position and a<2> is not disengaged in the allout position. Starting from the former position; the knob e is rotated and moves the plate a<1> by means of its segment g. As this plate nears the end of its travel, a lug o thereon engages a lug p on the plate a next to it, and the final movement of the plate a<1>, before it is moved out of mesh with the sleeve d, moves by means of the lugs o, p the next plate a into mesh with the sleeve d. This plate a is then moved by the control knob e until, as it in turn nears the end of its travel, a lug o thereon engages a lug p on the next plate a and the final movement before it gets out of mesh brings this next plate into mesh with the sleeve. Thus all the plates are moved in succession until the end plate a<2> 2 is withdrawn and abuts the stop j before its segment becomes disengaged from the sleeve. The The reverse operation is similar. The plate f carries a pin q which rotates a notched disc r step-by-step relative to each rotation of the knob. The disc r is marked corresponding to the plates and the number is seen through an opening s in the carrying plate t of the disc. The disc may have a plain part r<1> which engages the pin q to arrest the knob at the end of its travel. According to the Provisional Specification the teeth on the moving plates may engage a series of pinions on the shaft, and, to reduce hand capacity effects, a short shaft may be connected by gearing to the main shaft to serve as an operating member. The moving plates may further be mounted by disclike metal collars, the disc having a projection extending through a hole in the plate and secured in a hole in another disc so as to clamp the plate between the discs. Through the projection may pass the spindle and the teeth may be formed on one of the discs instead of the plate.

Filed: 1936-01-24
Abstract: N - acyl - 2 - cyano - 1.2 - dihydroquinolines or their nuclear substitution products are reduced with hydrogen in presence of a hydrogenation catalyst to 2 - acylaminomethyl - 1.2.3.4 - tetrahydroquinolines, which may be saponified.  The catalysts are preferably non - noble metal catalysts such as nickel or cobalt. Solvents for the catalytic reduction are ethyl acetate or decahydronaphthalene.  Both the acylated and deacylated products may be N-alkylated.  In examples: (1) N-benzoyl-2-cyano-1.2-dihydro-quinoline is hydrogenated using a nickel catalyst in alcohol or ethyl acetate or palladium black in ethyl acetate; the 2-benzoylamino-methyl-1.2.3.4-tetrahydroquinoline so obtained may be methylated to 1-methyl-2-benzoylaminomethyl - 1.2.3.4 - tetrahydroquinoline or saponified by alcoholic hydrochloric acid to 2 - aminomethyl - 1.2.3.4 - tetrahydroquinoline, which may also be methylated to 1-methyl-2-dimethylaminomethyl-1.2.3.4-tetrahydroquino-line and forms a citrate, a diacetate, and a benzylidene derivative with benzaldehyde.  Also in examples, the following compounds are hydrogenated in ethyl acetate with a nickel catalyst: (2) N-benzoyl-2-cyano-6-methoxy-1.2 - dihydroquinoline to 2 - benzoylamino - 6 - methoxy - 1.2.3.4 - tetrahydroquinoline which may be saponified with alcoholic hydrochloric acid; (3) N-benzoyl-2-cyano-8-methoxy-(or ethoxy)-1.2-dihydroquinoline; (4) N-benzoyl-2-cyano-1.2-dihydroquinaldine.  N - Benzoyl - 2 - cyano - 6 - methoxy - 1.2 - dihydroquinoline is obtained by the action of benzoyl chloride on 6-methoxyquinoline and potassium cyanide in water.  N - Benzoyl - 2 - cyano - 1.2 - dihydroquinaldine is obtained by the action of benzoyl chloride on quinaldine and potassium cyanide in ice-water.

Title: A method of counteracting the polymerisation of vinyl-methyl ketone during distillation or storage
IPC: C07C45/86
Filed: 1937-01-29
Abstract: Polymerization of vinyl methyl ketone during distillation or storage is counteracted by performing the distillation, advantageously under atmospheric pressure, in the presence of a free unsulphonated organic acid soluble in water and in vinyl methyl ketone, or by adding to the ketone before storage a quantity of such acid sufficient to ensure the presence of free acid.  A stabilizing agent such as hydroquinone or a copper salt may also be added.  The invention is applicable to the separation of mixtures of vinyl methyl ketone and a hydrocarbon, especially vinylacetylene, by distillation.  In examples: (1) and (3) acetic acid is added to vinyl methyl ketone and the mixture is distilled; (2) formic acid is similarly employed; (4) acetic acid is added to a mixture of vinyl methyl ketone and vinylacetylene, which is then fractionated by introducing it into the middle of a column heated to 80 DEG  C.  Other aliphatic carboxylic acids of low molecular weight, e.g. propionic, butyric or glycollic acid, may also be used.
