Title: Improvements in or relating to vibrating devices for measuring electrodes
IPC: B08B3/12
Filed: 1968-03-14
Abstract: 1,147,590. Cleaning electrodes. ELECTROFACT, N.V. March 14, 1968 [March 14, 1967], No. 12432/68. Heading G1N. A device for vibrating an electrode to effect cleansing thereof comprises a coil 1 energized with low frequency alternating current for reciprocating an armature 3, movement of which is limited in the downward direction when a flanged shoulder 9 abuts a plate 8 thereby transmitting shock impacts to the electrode (not shown) mounted in a seat 5. An adjustable nut 13 and lock nut 14 enable movement in the upward direction to be limited to enable further shock impacts to occur. A spring 10, the tension of which is adjustable by nuts 11, 12, resiliently urges the armature towards its lowermost position. In the case of a PH measuring electrode having a buffer liquid contained in a glass envelope, the buffer liquid is preferably viscous is that it exerts a strong damping effect of the thin conducting wire of the electrode.

Title: Improvements in or relating to centrifugal governors
IPC: G05D13/08
Filed: 1951-05-28
Abstract: 692,527. Centrifugal governors; elastic-fluid turbines. ONSRUD MACHINE WORKS, Inc. May 28, 1951 [Feb, 21, 1951], No. 12446/51. Classes 57 and 110(iii) [Also in Group XXIX] A centrifugal governor, particularly for controlling the flow of pressure fluid to a high speed turbine rotor 10 driving a rotary tool, comprises a centrifugally expansible elastic body 33 carried by a member 9 secured to a driving shaft 3 and an axially movable sleeve 25 radially confining the elastic body and abutting one end thereof, whereby the body is caused to expand axially under centrifugal force and move the sleeve which causes the speed to be controlled. The latter is keyed to the elastic body at 34 to ensure its return movement. The flow of pressure fluid from an inlet 14 through passages 15, 19 leading to a turbine nozzle 11 is controlled by a valve 16 which is loaded by a spring 21 and is subjected to fluid pressure on its front surface through the passage 15 and on its rear surface through passages 22, 22.1 in which an adjustable throttle 23 may be provided. A bleed passage 24. controlled by a shoulder 27 on the governor sleeve 25, is normally open to atmosphere so that the pressure on the rear of the valve 16 is reduced and the latter remains open. When the speed increases beyond a predetermined value the bleed passage 24 closes and full inlet pressure acts on the rear of the valve 16 and closes it. The bleed passage 24 is formed in a plug member 35 and the inner end of the passage is eccentric with the axis of the plug' member. Rotation of the latter adjusts the axial position of the inner end of the passage with respect to the shoulder 27 and thus the speed at which the bleed passage is closed. A second nozzle 11.1 uncontrolled by the governor is provided. In another embodiment the governor sleeve 25 is loaded axially by a spring washer. Instead of the second nozzle the valve 16 is provided with a restricted bore which is always open to the nozzle.

Abstract: The invention comprises a substituted thiazolecarboxylic acid hydrazide of the general formula: <FORM:0769481/IV(b)/1> wherein one of the symbols R, R1 or R2 denotes a mono- or dialkylcarbohydrazino or a nitrophenylcarbohydrazino, or an alkylidene- or carboxyalkylidenecarbohydrazino radical and the other two denote hydrogen, an alkyl radical of 1 to 6 carbon atoms or a phenyl radical.  Such compounds are obtained by reacting a haloketone or haloaldehyde of the formula <FORM:0769481/IV(b)/2> in warm anhydrous conditions with or without a solvent, with a thioamide of the formula: <FORM:0769481/IV(b)/3> or by reacting a thiazole-2-carboxylic acid, acid halide or amide with a substituted hydrazine of the formula H2NNR3R4 wherein R3 and R4 represent hydrogen, an alkyl radical of 1 to 6 carbon atoms, a phenyl or nitrophenyl radical or R3 and R4 denote an alkylidene or carboxyalkylidene radical provided that R3 and R4 do not both represent hydrogen.  Compounds of the first formula above where one of the symbols R, R1 and R2 represents an alkylidene- or carboxyalkylidene-hydrazino radical and the other two are as previously defined can be prepared by reacting a thiazolecarbohydrazide with a carbonyl compound of the formula R5COR6 wherein R5 and R6 may be alike or different and denote hydrogen, an alkyl radical of 1 to 6 carbon atoms, carboxy, or a carboxy alkyl radical.  In examples: (1) thiazole-2-carboxylic acid hydrazide (prepared as described in Specification 769,482 is reacted with pyruvic acid to give pyruvic acid thiazole-2-carboxylhydrazone; (2 (a)) thiazole-2-carboxylic acid and 2 : 4-dinitrophenylhydrine are reacted to give 2-thiazolecarboxylic acid 2,4-dinitrophenylhydrazide; (2 (b)) thiazole-2-carboxamide and 1,1-diethylhydrazine are reacted to give a -thiazolecarboxylic acid 1,1-diethylhydrazide; (2 (c)) ethyl hydrazine and thiazole-2-carboxylic acid chloride are reacted to give thiazole-2-carboxylic acid ethylhydrazide; (3) a -keto-b -chlorobutyric acid and sodium bisulphite are reacted to give the addition compound, which with hydrazine gives a -keto-b -chlorobutyric acid hydrazide.  This is reacted with thioformamide, and treatment of the 5-methyl-4-thiazolecarboxylic acid hydrazide obtained with acetone gives acetone 5 - methyl - 4 - thiazolecarbonylhydrazone; (4) 1-bromo-1-phenylacetone and acetone mono-thioamide oxalylhydrazone (from the reaction of mono-thio-oxamide and acetone hydrazone) are reacted to give 4-methyl-5-phenyl - thiazole - 2 - carbonylhydrazone; (5) ethyl mono - thio - oxamidate and phenylhydrazine are reacted and the product is reacted with chloracetaldehyde to give 2-thiazolecarboxylic acid phenylhydrazide.  The haloaldehydes, haloketones and thioamides can be prepared by reaction of the appropriately substituted acid, anhydride, amide, ester or acid halide with a hydrazine of the formula H2NNR3R4 or with a hydrazone of the formula <FORM:0769481/IV(b)/4> where R5 and R6 are hydrogen or alkyl, carboxy or carbalkoxy radicals.
