Title: Process for eliminating the acidity of acid activated charcoal
IPC: C01B31/08
Filed: 1928-02-14
Abstract: 285,386. Verein f³r Chemische und Metallurgische Produktion. Feb. 14, 1927, [Convention date]. Carbon.-The acidity of charcoal, which has been activated by acidic materials or by salts which owing to hydrolytic decomposition exhibit an acid reaction, is removed by treatment under pressure with milk of lime, sodium carbonate, sodium hydroxide, or other alkaline materials at temperatures over 100‹ C, e.g. 150‹ C. Sufficient alkaline material may be employed to give an alkaline charcoal. The charcoal will remain alkaline when soda is used, but with milk of lime on exposure to the air it becomes gradually neutral owing to absorption of carbon dioxide.

Filed: 1922-02-17
Abstract: 197,430. Hiley, A., and Le Bas, E., (trading as British Steel Piling Co.). Feb. 17, 1922. Steam hammers; cushioning reciprocating parts.-In constructing concrete piles according to the method described in Specification 179,699, [Class 68 (ii), Subaqueous buildings &c.], the concrete is deposited from a preparatory tube and is tamped and consolidated by vertical vibratory movements given to the tube by a hammer striking both upwardly and downwardly, the same hammer being preferably used for driving the tube. The hammer comprises a moving cylinder B with a stationary piston, steam being admitted above the latter to raise the cylinder which falls by its own weight and strikes the cap A<1> of the tubes A. To withdraw the tube, the hammer and the cap A' are hoisted up the girders of the frame A<x> in which they are guided by projections B<0>, A<0>, A<01>, to enable reinforcement bars and a charge of wet concrete to be introduced into the tube through an aperture a' in the casting A<3>. The hammer and cap are then lowered and links C, C are fitted on to the casting A<3>. Attached to the upper parts of the links are blocks C', C' serving as an anvil against which the cylinder strikes. The full stroke of the hammer is not used in this operation, and springs C<2>, C<2> are interposed between the links and the suspension ropes C<3>, C<3>. The lower ends of the links C, C are bolted to projections a<3>, a<3> on the casting A<3>, so that the upward impulses of the hammer striking the anvil blocks C<1>, C<1> are transmitted to the tube. Admission and exhaust of steam to the cylinder is controlled by a valve at the head of the stationary piston-rod b<1> actuated by a hand line D<1> through a lever D. In extracting the tube, an auxiliary check line D<2> connected to the lever D is operated by projections b<x> on the cylinder engaging a nut d' on the Jine D<2> to admit steam above the piston at a predetermined point during the down stroke of the cylinder to cushion the downward blow. The line D<2> may have a spring D<3> inserted therein.

The antibiotic substances are recovered by extracting the filtered broth at alkaline pH with a water-immiscible organic solvent or by extracting the separated mycelium with aqueous acid, alkalifying and extracting the alkaline solution with water-immiscible solvent. The extract is purified and concentrated by conventional procedures, e.g. absorption on ionexchangers, solvent-solvent transfer and precipitation and recrystallization. The SF-837 is then isolated by chromatography and fractional elution, e.g. on carbon, alumina, silica gel, ionexchangers or cellulose derivatives, or by countercurrent distribution procedures using phosphate buffer and benzene partition. The antibiotic is finally isolated by evaporation of the solvent, freeze drying or precipitation by pH change or addition of a non-solvent. It may be converted to its acid addition salt by precipitation with the required acid from organic or aqueous-organic solution. By treatment with acetic anhydride in pyridine, the SF-837 may be converted to its novel di-acetyl derivative. Antibiotic SF-837 and its di-acetyl derivative are believed to have the following structural formula wherein R 1  and R 4  are each -COCH 2 CH 3 ; and in the case of SF-837 itself R 2  and R 3  are each H, whereas in the acetyl derivative R 2  and R 3  are each -COCH 3 . Pharmaceutical compositions having antibiotic activity against Gram-positive organisms comprise antibiotic SF-837 and/or its salts and diacetyl derivative together with a pharmaceutically acceptable carrier or diluent.

Title: Well logging system
IPC: G01S1/72
Filed: 1959-02-16
Abstract: 845,635. Geophysical prospecting. SOCONY MOBIL OIL CO. Inc. Feb. 16, 1959 [Feb. 17, 1958], No. 5342/59. Class 40(7). A well logging system in which signal pulses, corresponding to the reception of signals at two separated points in a well bore, are transmitted to measuring means at the earth's surface is characterized by control means for applying first and second received pulses separately to a common signal channel and means for delaying the transit of the second pulse for a predetermined time interval that exceeds the time required for transmission of the first pulse and for actuation of the control means. Crosstalk between the received signals in the transmission system is thus avoided. On transmission of acoustic impulse 20 by transmitter T a contemporaneous synchronizing signal opens gate 63 via gate 61. Receiver R1 output 21 is applied through switch 32, line 39 and gate 63 to initiate a sawtooth voltage by "boot-strap" generator 80-82 via monostable multivibrator 65 and delay circuit 60. Gate 63 concurrently provides a signal on line 43 to actuate relay 38 and receiver R2 output 22 delayed in unit 34 by a time t<SP>1</SP> is thereafter transmitted up-hole via line 39. The inherent delay in relay operation is indicated by diagram 48 in relation to the timing of the transmitted ;and received pulses. Receiver R2 pulse, via capacitor 100 and valve 101 opened by multivibrator 65 on receipt of receiver Rl pulse, triggers blocking oscillator 104 whose secondary windings 117, 119 outputs operate electronic switch 84 momentarily to apply the sawtooth voltage on line 83 to storage capacitor 87 connected to recorder 88 whose paper is fed synchronously with the "down-hole" equipment movement, Fig. 1 (not shown). Delay unit 60 may be omitted, the recording pen being biased by an amount corresponding to unit 34 delay. Unit 34 may consist of an inductor/capacitor network, Fig. 3 (not shown).
