Title: Improvements in or relating to organic amino acids
Inventor: SIMONS CHARLES
Filed: 1948-11-16
Abstract: a -Amino-o -guanidyl monocarboxylic acids are prepared by reacting an a -o -diamino monocarboxylic acid containing not less than four carbon atoms or an acid salt of said amino acid with a basic copper compound followed by the addition of alkali and an S-alkyl isothiouronium salt.  Specified copper compounds are copper oxide, copper hydroxide and copper carbonate.  In examples: (1) ornithine monohydrobromide dissolved in water is refluxed with copper oxide. The liquid is then filtered and concentrated and ammonia and S-methyl isothiouronium sulphate added, the temperature not being allowed to rise above 0 DEG  C.  The liquid is then allowed to stand in a refrigerator and after filtering off the sludge formed the filtrate is dissolved in water and shaken with an aqueous solution of flavianic acid and the mixture again placed in a refrigerator.  The solid flavianate formed is filtered off and then treated with concentrated hydrochloric acid to yield p  crystals of arginine mono-hydrochloride; (2) L-lysine mono-hydrochloride dissolved in water is refluxed with copper oxide and after filtering and concentrating the liquid is treated with ammonia and S-methylisothiouronium chloride at 0 DEG  C.  The mixture is then filtered and the filtrate evaporated to a gum and then extracted with an aqueous solution of flavianic acid at 0 DEG  C. The solid flavianate is then decomposed with sulphuric acid to yield L-mono-arginine.

Abstract: 283,193. Associated Telephone & Telegraph Co., (Assignees of Stehlik, R. F.). Jan. 8, 1927, [Conventin date]. Automatic exchange systems.-In a system employing bi-directional call-finders, the magnets of the callfinders are controlled by common apparatus associated with the finderallotter, and a back-acting release magnet also serves as the switching relay. The system also includes the following features-(1) a calling line is marked busy in the connector banks by the line relay as soon as the loop is closed, (2) a by-pass circuit is completed over an extra wiper of the finder-allotter to the line relay of the group selector to enable dialling to begin before the call. finder is set on the calling line, (3) a second call cannot be initiated while a call-finder is being set on a calling line, and in the case of simultaneous calls, the by-pass circuit is not completed. Normal operation. Line relay 2 upon energization locks in a local circuit in series with marginal relay 205 which is normally inoperative, grounds the connector test multiple, connects up start relay 203, marks terminals in the banks of the vertical and rotary counting switches VCS, RCS, and extends the calling loop over wiper 74 of the finder-allotter FA to line relay 8 of the group selector S. The subscriber receives dialling tone, and impulsing may begin over this by-pass circuit. The sequence switch SQ is advanced continuously by an interrupter 225, and a similar interrupter 226 is connected over the first ten terminals of wiper 221 to the vertical magnet 6 of the call-finder F and to magnet 202 of the switch VCS. When the latter reaches the marked terminal, interrupter 226 is short-circuited, and the switches take a final step when the sequence switch moves to the 11th position. The second ten terminals of the sequence switch are multipled to the rotary magnet 7 and to magnet 201 of the switch RCS, a terminal of which is marked in a similar way over wiper 209 of the switch VCS. In the 21st position, an impulse is sent to energize the release magnet 5 of the call-finder F, which locks and acts as a switching relay. Cut-off relay 1 energizes, disconnects line relay 2, and opens the by-pass circuit. In the last position of the sequence switch SQ, the finder-allotter FA advances into engagement with the next idle callfinder, guard relay 204 being energized meanwhile, disconnecting start relay 203. The sequence switch stops in its normal position, and the switches VCS, RCS restore. Simultaneous calls. The energization of start relay 203 removes battery from the remaining line relays of the group, so that a second call cannot be initiated while a call-finder is being set on a calling line. If two calls are initiated simultaneously, marginal relay 205 energizes over the locking circuits of the two line relays, connects up line relay 8 of the group selector S, but holds open the by-pass circuit. The calling line having the lower designation is served first, and dialling cannot take place until the call-finder switches through.

Title: Method for the solid-phase bonding of metals
IPC: B23K20/04
Filed: 1951-12-31
Abstract: 745,511. Making composite sheets &c. METALS & CONTROLS CORPORATION. Dec. 31, 1951 [Jan. 5, 1951], No. 30507/51. Classes 83 (2) and 83 (4). Rolling.-A method of bonding two metals comprises heating at least one of them to a temperature above the minimum recrystallization temperature and below both the " hotshort " temperature and the temperature at which a liquid phase or a brittle intermetallic compound would form, pressing the metals together in a protective atmosphere to cause initial bonding and finally heat treating the initially bonded stock to increase the strength of the bond. Metal strips from coils 1 and 3 are passed through pinch rolls 5 or 7 and idler rolls 9 into a furnace 11 from which they emerge through a guide 13 into the pass of a rolling mill 19 which effects an initial bonding of the strips. The pinch rolls impart a tension to the strips as they pass through the furnace. As the strips leave the guide 13 they are pressed down by a weight bar 39. A reducing atmosphere is maintained in the furnace and in the guide 13 and jets of reducing gas may be directed against the edge of the strips between the guide and the mill 19. The temperature of the rolls is greatly below that of the work and they therefore having a chilling effect. It is thought that this treatment causes bonding of the metals at a number of isolated spots. The work is next heat treated to cause a growth of the interfacial bonds, the temperature preferably being above the minimum recrystallization temperature of the metal but below the temperature at which any brittle intermetallic compounds or liquid phase material would form. In an example, strips of fine silver and an alloy known under the Registered Trade Mark " Monel " were cleaned by wire brushes, passed through a furnace heated to 1200‹ F., entered the roll pass at 900-1000‹ F. and were reduced about 32.5 per cent. The rolled strip issued from the mill at about 12 feet per minute and was wound into a coil which was heat treated for about 100 minutes at 1300 ‹ F. For bonding two strips of steel, the furnace temperature was 1500‹ F., the strips entered the roll pass at 1100-1200‹ F. and were reduced 20 per cent. The subsequent heating was for 45 minutes at 1400‹ F. A nickel strip and a steel strip were passed through a furnace heated to 1800‹ F., entered the roll pass at 1400-1500‹ F. and underwent a 46 per cent reduction followed by heat treatment at 1350‹ F. for one hour. A number of curves show the minimum deformation required to bond various metals together at a particular temperature.
