Title: Process for the manufacture of antibiotics
IPC: A61K/
Filed: 1948-08-27
Abstract: An antibiotic, (l) - #Y - 1 - p - nitrophenyl - 2 - dichloroacetamidopropane-1 : 3-diol, is obtained by cultivating Streptomyces venezuelae in contact with a nutrient medium under aerobic conditions (i.e. on the surface of the medium, e.g. for 10-15 days at 25 DEG  C., or in the submerged condition with aeration and agitation, e.g. for 2-7 days at 25 DEG  C.).  The nutrient medium is preferably an aqueous medium containing an assimilable carbon source (a polyhydric alcohol or a mono-, di- or poly-saccharide, e.g. glucose, fructose, sucrose, inulin, dextrins, starches and especially sugar alcohols such as sorbitol and particularly glycerol) and a proteinaceous material (unmodified protein or protein degradation products such as proteoses, peptones, polypeptides, peptides and amino acids).  The carbon source or the proteinaceous material or both together may also be provided by various complex products, e.g. liquefied or modified starches, molasses, corn syrup; acid or enzyme hydrolysed casein, distillers' grain slops, distillers' solubles, soybean meal, acid hydrolysed corn or wheat gluten, peptone, brewers' yeast, offals, synthetic mixtures of amino acids; whey concentrates, grain p  mashes, corn and wheat steep liquor.  The antibiotic may be isolated from the culture medium by the following series of steps: (a) clarifying the liquid below about pH 10; (b) extracting the solution with an organic solvent having a solvent-water distribution coefficient for the antibiotic above about 9 (e.g. cyclohexanone, butanol, ethyl acetate or methyl isobutyl ketone); (c) removing the solvent from the extract; (d) extracting the residue with an organic solvent having a distribution coefficient between about 1 and 9 (e.g. nitrobenzene, nitromethane, diethyl ether or ethylene dichloride); (e) washing the extract with dilute mineral acid and water (and preferably also with dilute alkali); (f) adding water to the organic solvent extract; (g) evaporating the organic solvent from the mixture; (h) extracting the aqueous solution with an organic fat solvent in which the antibiotic is substantially insoluble (e.g. benzene or petroleum ether); (i) evaporating the aqueous solution to the point of crystallization. Alternatively, steps (b) and (c) may be omitted, the clarified solution being directly extracted with the type of solvent used in (d).  Again, when the solvent used in (d) is a lower dialkyl ether, the washing step (e) may be replaced by passage of the solution over an aluminium oxide type adsorption column.  A further alternative consists in adsorbing the antibiotic from the clarified culture liquid on to activated charcoal, eluting it with ether or 80 per cent acetone, adding water, distilling of the organic solvent, removing any gummy material which separates and concentrating the aqueous solution to the point of crystallization. Examples illustrate various features of the invention.

Title: Improvements in or relating to stop-motions for textile and other machines
IPC: D03D51/00
Filed: 1921-04-27
Abstract: 183,147. Derry, R. H. April 27, 1921. Gearing for stopping and starting machinery.-In stop-motions for textile and other machines wherein a catch is automatically operated when a defect occurs to release the belt-shifter which is then actuated by a spring so as to move the belt on to the loose pulley, the catch is provided with a device which after the machine is automatically stopped, allows the belt-shifter to be operated to effect a partial starting of the machine but prevents the complete operation for continuous running until the catch has been reset by the remedying of the defect. A lever 21 is provided with a pivoted catch 24, which normally engages a stop 26 on a part 28 of the belt-shifter so as to retain the belt on the fast pulley 33, and with a stop 25, which is adapted to engage a stop 2.7 on the part 28. A solenoid 18 attracts an armature 20 on one end of the lever 21 when a defect occurs and so releases the belt-shifter, which is then moved by a spring 30 so as to place the belt on the loose pulley 34 but can be moved to the intermediate position determined by the stop 25, as shown in Fig. 6. The circuit of the solenoid is closed by a plunger 13 carried on a lever 7, which is normally upheld by the intact lap, sliver, yarn, &c. but, upon the breakage or slackening thereof, tilts and projects the plunger into a mercury cup 15. The lever is automatically restored to its normal position when the lap &c. has been pieced, thus breaking the circuit of the solenoid and releasing the stop 25. The cup 15 is provided with a cover 17, Fig. 3, having a tubular stem 17a, whereby the contacts are protected from dust and fly.

Title: Improvements in spring forming and tempering machines
IPC: B21D53/88
Filed: 1920-08-09
Abstract: 171,162. Smulski, T. J., and Schulz, E. F. Aug. 9, 1920. Springs.-In a machine for making automobile and like springs, each leaf is bent between pivoted curved bars. The bars are then locked together and lowered into a tempering bath. Fig. 4 shows a machine with six bending-heads for tempering the leaves of a six-leaf spring. Each head consists of parts 9, 14, pivoted together at 17, the part 9 being pivoted on a spindle 10. Each part 9, 14 consists of side bars spaced by bolts. A knob 25 is carried by spaced plates, pivoted to the side bars 14 by a pin 24, and acted on by a spring 33, engaging the nut 31 of a bolt which is pivotally connected to the side bars at 32. The leaf is placed on the part 9 between end stops and side stops 54. The part 14 is then closed down on the part 9 by the descent of a bar 57, which slides in guides 5 and engages the knob 25, the part 9 being supported by a cam 46 on a shaft 47, which is rotated by a ratchet-wheel and pawl. The parts 9, 14 are then locked together by a latch 37, pivoted to the part 9, and engaging a pin 28 projecting through a slot 29 from the plates which carry the knob 25. The cam 46 then allows the bending-head to fall into the tempering-bath 1, in which it remains while the other five bending-heads are raised in succession by their separate cams. The cam 46 then raises the first bending-head, and a pin on the cam trips the latch 37, allowing a spring 20 to open the parts 9, 14. The bar 57 is reciprocated by connecting-rods from toothed wheels 61, driven by pinions 74 on a shaft 75. The spindle 47 is partially rotated at each descent of the bar 57 by ratchet gearing operated by connecting-rods 65 from bars 62, pivoted at one end 63 to the framing and slotted at the other end to engage the gudgeon pins of the bar 57. The shaft 75 is driven by a belt pulley through a clutch controlled bv a four-armed lever, one arm of which carries a bowl 88 engaging a cam 86 on the shaft 73. After one revolution of the shaft 73, the bowl enters a notch in the cam 86, and the clutch is uncoupled, and the machine stopped. The bowl can be lifted and the machine restarted by means of a foot-lever 82. In order to permit circulation of the tempering-fuid. the side bars 9, 14 may be perforated, or formed with undulated edges. In modifications, each part 9, 14 consists of three parallel spaced bars, or of a single bar of U or T section. In another modification, each part 9, 14 carries spaced pins which engage the work.

Title: Improvements in liquid fuel burners
IPC: F23D11/10
Filed: 1920-08-09
Abstract: 171,163. Alexander, A. E., (Best, Inc., W. N.). Aug. 9, 1920. Spray burners.-In a burner for liquid or semiliquid fuels in which the fuel passage 11 terminates in an upwardly-directed outlet 13 and the passage 12 for the expansible spraying-medium such as steam or air, terminates in an outlet 16 directed substantially at right-angles across the fuel outlet 13, the outlet 16 is formed between a flat face 14 on the burner and a mouthpiece 17 which fits in a recess 17<x> beneath an upper flange 18 and may be moved across the oil outlet by means of bolts 19 extending through the burner body. This movement causes any foreign substance clogging the outlet 16 to be deposited in the fuel outlet 13, and on returning the mouthpiece 17 by tightening up nuts 20 on the bolts 19, the foreign substance passes out with the fuel. Excessive movement of the mouthpiece 17 is prevented by cotter pins 21 limiting the movement of the nuts 20. The mouthpiece is prevented from moving upwards by dowel pins 22, the flange 18, or other means. The outlet wall of the passage 11 is cut away at the outlet to form an outwardly flaring recess 15. The outlet 16 is slightly wider than the outlet 13 and is preferably slightly higher at its side edges than at the middle so that the resulting fan-shaped spray will be of uniform thickness. In a larger burner, shown in Fig. 4, two parallel clamping bolts 19a are provided extending through lugs or flanges 23, 24 on the burner body. The bolts 19a may have square heads 26 inserted in slots 25 in the mouthpiece 17a instead of being rigidly secured thereto. The burner body is formed with integral lugs 27 for clamping purposes.

Abstract: 985, 652. Measuring electrically. OFFICE NATIONAL D'ETUDES ET DE RECHERCHES AEROSPATIALES. June 28, 1961 [July 1, 1960], No. 23371/61. Heading G1N. In a manometric pick-up device comprising a pressure-displaceable conductive diaphragm which constitutes one electrode of a capacitor, the other electrode is fixed and has a concave pole face, the diaphragm being supported at its periphery on a seat which forms part of the same geometrical surface as that of the concave pole face. In Fig. 7, a fixed circular electrode 38 is formed integral with a rod 41, the shoulder between them being seated in a recess 44 in a block 42 of insulating material. The face 37 of electrode 38 is concave and co-operates with a circular plane electrode 40 formed by the central portion of a metallized plastic diaphragm secured around its edges, as by screws 52, between complementary curved portions of block 42 and a conductive ring 47, said curved portions being located on the same sphere as the concave face 37 of electrode 38, the diameter of which is smaller than that of electrode 40. To provide damping, the surface of the fixed electrode may be channelled. Variation of capacitance of the device consequent upon change of pressure upon electrode 40 is measured in a circuit 48. In Fig. 11, ring 58 is of insulating material, electrical connection with the diaphragm being effected through a stud 59 and rod 60 located in a bore in the block 42. In a differential arrangement, Fig. 13, two concave-faced electrodes 71, 72 in bores in insulating block 70 co-operate with a single diaphragm 81 which forms two plane electrodes 82, 83 across pressure chambers 79, 80 in ring 77, the capacitors so formed being connected into a bridge circuit comprising fixed capacitors 89, 90, which is supplied at terminals 91 and produces an output at terminals 92, 93; this arrangement may be used to provide compensation for unwanted variables or to compare two pressures. In Fig. 15 a metal diaphragm 100 is clamped at its periphery between a block 102 and a washer 103, a ring 109 inside the washer being urged by a nut 113 against the diaphragm to seat it against the part-spherical seating 105 of the block 102. To ensure that the surfaces of the fixed electrode(s) and conductive stud (if any) and the seating portions of the insulating block lie on the same sphere they are ground together after assembly with a spherical tool; the ring which co-operates with the block is ground with a complementary concave tool.
