Title: Seismic amplifier
IPC: H03G3/20
Filed: 1964-07-01
Abstract: 1,036,647. Amplifier with automatic gain control; seismic prospecting. JERSEY PRODUCTION RESEARCH CO. July 1, 1964 [July 26, 1963], No. 27175/64. Headings H4D and H4R. A seismic amplifier is provided with automatic gain control by attenuator sections 18, 36, 50, 64, and 78, Fig. 1, inserted between amplifier stages in which the attenuators are normally in circuit but are short-circuited by switches 26, 44, 56, 70, and 84, when the amplifier output falls below a predetermined level. The arrangement is such that the gain of the amplifier is successively doubled by the operation of the switches in an order determined by the counter circuit 93 and the gates 97 and 98 to give sixteen different gain conditions. The control circuit 92 is shown in Fig. 4 and is such that whenever the output signal level of the amplifier fed to the Schmitt triggers 85 and 89 exceeds a predetermined positive or negative value one or other of triggers 85 or 89 operates and charges capacitor 104 to a negative potential. The potential on capacitor 104 leaks away through resistor 106 and, if the predetermined signal level is not again exceeded within the appropriate discharge time of the capacitor resistor circuit, the triggering potential of trigger 110 is exceeded and the trigger operates to send a counting pulse to the counter circuit 93, Fig. 1. At the same time the trigger circuit 110, Fig. 4, provides an enabling input to gate 122 and so allows the following pulse from clock 124 to trigger the monostable circuit 126. The output from circuit 126 is fed to the capacitor circuit 102 to maintain this circuit's output below the triggering level of trigger 110 for a predetermined time so that only one pulse is sent to the counter during the time which is required for the system to react. The sequence of inserting the various attenuator stages obtained by the gating system shown with the counter in Fig. 1, and the gain of the amplifier, each stage of which has a gain of 8 x, with attenuator stages of specified losses is indicated in a table, Fig. 2 (not shown).

Abstract: 394,959. Reproducing photographic sound-records. SIEMENS & HALSKE AKT.-GES., Siemensstadt, Berlin. Oct. 2, 1931, No. 27466. Convention date, Oct. 31, 1930. Void [Published under Sect. 91 of the Acts]. [Class 40 (ii).] Gamma value errors in photographic soundrecords are wholly or partially compensated for in the reproduction of sound from the film by adapting the spectral composition of the reproductive light to the spectral absorption of the record and to the sensitivity of the light sensitive member. For this purpose colour filters, colour wedges or the like combined or coupled with neutral grey filters, wedges or other light obscuring devices such as diaphragms are interposed in front of the light so that the effective action of the light falling on the selected light sensitive member will effect the desired compensation. Alternatively the light source may be varied by varying the incandescence of the lamp filament. The gamma value may be partially compensated for in preparing the record by dyeing the positive record film, for example by tinting with uranium or copper, and printing it with light of suitable wave length, for example blue light ; in addition the negative record may be dyed. Such preliminary treatment may include colouring the silver sound record by a known toning or intensifying process, or may be effected in the pinatype process.

Title: Improvements relating to the recovery of platinum from alumina-platinum-containing catalytic materials
IPC: B01J23/96
Filed: 1954-09-24
Abstract: In the recovery of platinum from alumina - platinum - containing catalytic material the material is digested with sulphuric acid to produce a solution of aluminium sulphate containing in suspension platinum which is flocculated and separated.  Preferably sulphuric acid is used in excess of the amount required to dissolve the alumina e.g. an excess of 5-15 per cent of a 20-50 per cent sulphuric acid solution is used and the digestion temperature may be 80-110 DEG C. Small amounts of platinum which may go into solution may be precipitated by bubbling through hydrogen sulphide either before or after separation of the suspended platinum.ALSO:Platinum is recovered from alumina-platinum-containing catalytic material by digesting the material with sulphuric acid, preferably in stoichiometric excess, whereby the alumina goes into solution and the platinum remains in suspension, flocculating the platinum and separating it from solution.  Preferably 5-15 per cent excess of 20-50 per cent sulphuric acid is used in the digestion.  The resulting solution may be diluted to a content of say 14 per cent aluminium sulphate prior to separation of the platinum.  Small amounts of platinum in solution may be recovered with or after removal of suspended platinum by treatment of the solution with hydrogen sulphide.
