Abstract: 1476613 Controlling yeast cultivation CHEMOPETROL KONCERN PRO CHEMICKY PRUMYSL A ZPRACOVANI ROPY 15 Oct 1975 [16 Oct 1974] 42131/75 Heading C6F A method for the aerobic cultivation of microorganisms, particularly yeast, in a nutrient medium including potassium dihydrogen phosphate, an ammonium salt of a strong mineral acid and a carbon source material, involves maintaining the pH value between 2 and 6 by addition of an inorganic base, and adding further carbon source material at a time when the concentration of the carbon source material in the cultivation medium drops below that producing a growth rate of half the maximum. This reduction gives rise to a sharp increase in the concentration of oxygen dissolved in the cultivation medium and, in carrying out the method of the invention, when the increase over the "steady state" concentration of oxygen dissolved in the cultivation medium that is exhibited when the optimum concentration of the carbon source material exists, amounts to 5-90% of the saturation concentration of oxygen at the temperature and pressure of the cultivation, the carbon source material is added in an amount such that the dissolved oxygen concentration is decreased to the "steady-state" value within between 5 seconds and 2 minutes. Between 75% and 85% of the theoretically deduced amount of the carbon source material may be added together with the inorganic base (ammonia). The Examples are directed to the controlled cultivations of Candida utilis and Candida bipolytica with non-microbiologically produced ethanol and C 14 -C 17  n-alkanes, respectively, as carbon source materials.

Title: Mechanical clutch brake

Filed: 1971-09-10
Abstract: 1321414 Mechanical clutch brake BENDIX CORP 10 Sept 1971 [30 Sept 1970] 42301/71 Heading F2E The connection-brake device comprises three parts, namely, a rotatable driving member 10, Fig. 1, a rotatable driven member 14, and a rotationally-fixed braking member 40, wherein the driven member is frictionally engageable with the braking member by means of first and second friction surfaces 26, 28, provided on flexible first and second supports formed by bifurcating at 16 the end of the driven member, the driving member 10 being operatively connected (e.g. at 12, 34, 36) to the first and second supports to impose a torque thereon tending to flex them and thereby disengage the friction surfaces 26, 28, from the braking member 40 to a variable degree. In the embodiment of Figs. 1 and 2 the driving and driven members are circular in crosssection but the driven member 14 is cut away at 22 and 24 to define the friction surfaces 26, 28, and is transversely grooved at 30 and 32 to define the lugs 34 and 36 which are separated by slot 16 and are engaged for driving by slot 12 in the end of member 10. The arcuate friction surfaces 26, 28 are urged radially outwardly into contact with surface 38 of member 40 by the resilience of the arms on which they are formed. When driving torque (provided, e.g. by an electric motor) is applied by driving member 10, lugs 34 and 36 are urged towards each other, the frictional load at 26, 28, being thereby lessened. If the load torque imposed on the output member 14 is sufficiently high, the frictional load will be eliminated altogether. If no load torque is imposed on output member 14, the reduction of frictional load is a function of driving torque. In the more elaborate embodiment of Figs. 3 and 5, shafts 10 and 14 are axially aligned by engagement of slightly reduced diameter portion 52 in the interior of shaft 14. The largerdiameter end 60 of shaft 14 is transversely slotted, and the shaft is axially slotted at 72, 74, to provide two pairs of lugs 68, 70, any one pair 68, 70, being engaged by a recess 54, Fig. 5, in the side of a full-diameter portion of shaft 10. The shoulder between this portion and fullyreduced portion 50 of shaft 10 engages the slots above and below lugs 68, 70, as shown in Fig. 3. Brake " drum " 76, engaged by arcuate surfaces 64, 66, is screwed to a plate 84, and the plate 84 is free to move away from a fixed support 48 (which has a bore 46 for shaft 10), by the clearance between the head of bolt 90, engaging slot 88, and support 48. The fully-reduced portion 50 of shaft 10 permits the radiallyinward flexing of the arms carrying lugs 68, 70, in operation of the device.

The hinge mechanism includes a pair of levers 67, 68 hinged, at 82, 83, to the base 20a, hinge plates 71, 72 rigidly secured to the respective frames 21a, 22a. A pivot pin 97 on plate 71 engages a hole 98 in lever 67 and a pivot pin 95 on lever 68 engages through a hole 94 in plate 71 into an end of a rod 74. Rod 74 forms part of a seat locking assembly 113 which further includes a rod 73 parallel and rigidly attached to the first rod 74. The rod 73 has an end 100 engaged in an arcuate slot 101 in plate 71 and is normally biased by a spring 76 into a notch 103 in plate 72 to hold the frames 21a, 22a against movement relative to each other.

Abstract: 1286104 Aircraft with variable sweep wings MESSERSCHMITT-BOLKOW-BLOHM GmbH 5 Sept 1969 [25 Sept 1968] 44083/69 Heading B7G An aircraft has variable sweep wings 4, each having a root area extending from swivel axis 45 and an outer area extending from the root area to the wing tip, the outer area being stiffened by chordal ribs 41 or stringers and the root area by webs 42, Fig. 4, or stringers 43, Fig. 5, varying in direction with respect to the spanwise axis of the wing. The webs 42 may radiate from the swivel axis 45; or the stringers 43 may vary in their inclination to the spanwise axis from 45 degrees near the swivel axis to 90 degrees where the root area meets the outer area. Thus the wing has high torsional rigidity about the spanwise axis and low flexural rigidity along that axis so that in the swept-back position the angle of attack decreases from root to tip (since the trailing edge of a cross-section 7 is at a greater distance from the root mounting than the leading edge) to a greater extent than in the unswept position, whereby the tendency of the centre of lift to shift backwards as the wing is swept backwards to be reduced or avoided.
