Title: Improvements in or relating to supersonic testing apparatus
IPC: G01N29/30
Filed: 1946-12-06
Abstract: 641,790. Supersonic inspection devices. SPERRY PRODUCTS, Inc. Dec. 6, 1946, No. 36125. Convention date, Dec. 21, 1945. [Class 118 (ii)] In supersonic testing apparatus comprising a pulse generator, oscillator, and receiver, the piezo-electric transmitter crystal determines the frequency of the oscillator. The pulse from a generator 10 is impressed upon a piezo-electric crystal 11, which acts as a transmitter and receiver crystal, in engagement with a workpiece 12. The crystal is connected to an amplifier 15 coupled to an oscilloscope 16 associated with a sweep circuit 20. The generator 10 includes an oscillator 30 upon the control grid 31 of which is normally placed a relatively large negative bias by a trigger valve 32. To transmit a pulse, a square wave from a generator means 40 passes through an amplifier 34 and inverter 35 to place a bias on the grid 33 of the trigger valve 32 sufficient to render the latter non-conductive, thus reducing the negative bias on the grid 31 to allow the oscillator 30 to produce the desired pulse. The duration of the pulse is varied by a variable potentiometer 37. The usual variable tuned circuit for the oscillator 30 is excluded in this case, since it is found that the crystal 11 automatically tunes the oscillator. Specification 641,095 is referred to.

Title: Improvements in or relating to processes of producing copper hydroxide
IPC: C01G3/02
Filed: 1937-12-31
Abstract: 508,495. Copper hydroxide; artificial silk. NEW PROCESS RAYON, Inc. Dec. 31, 1937, No. 36237. Convention date, Jan. 4. [Class 1 (iii)] [Also in Group IV] Copper hydroxide, which may contain copper oxide, is obtained by aerating a suspension of copper sulphide in a solution of a soluble inorganic alkaline material other than ammonia. The copper sulphide used may be finely powdered copper sulphide ore, but preferably it is obtained as follows:-a cuprammonium solution of cellulose is precipitated with caustic soda, and the part of the copper dissolved in the caustic soda liquor is precipitated by adding say, sodium, potassium or ammonium sulphide. The quantity of alkali employed in the conversion of the copper sulphide should be in excess of that required for forming alkali thiosulphate with the sulphur content of the sulphide, and sufficient may be present in the precipitate obtained as above, which is not washed unless the alkalinity is above the desired value. Suitable alkalis for the conversion are caustic soda and potash, and alkali carbonates, e.g. sodium carbonate. The copper hydroxide obtained may be dissolved in the waste acid liquor containing copper which has been used to wash the regenerated cellulose. Basic copper salts may be precipitated from the neutral sulphate solution obtained. A statement of the art relates to washing of the precipitated copper sulphide obtained as above and digesting it with sulphuric acid in the presence of an oxidizing agent such as chlorates or peroxides, and treating the resulting copper sulphate solution to remove iron, and to form copper hydroxide.
