Title: Process for working up oil-containing fermenter run-offs
Inventor: RUDEL MANFRED
IPC: C10G32/00
Filed: 1967-09-06
Abstract: 1,146,126. Recovering oils. DEUTSCHE AKADEMIE DER WISSENSCHAFTEN ZU BERLIN. 6 Sept., 1967, No. 40808/67. Heading C5E. [Also in Division C6] In working up oil-containing fermented runoffs obtained by the aerobic fermentation of mineral oil fractions, such as diesel oil fractions, with micro-organisms, particularly yeasts, the fermented run-off or a product formed therefrom by standing for some time, which contains the micro-organisms and is a suspension and/or emulsion of oil and micro-organisms in nutrient medium, is subjected to a gravitational field, whereby phase reversal takes place, resulting in the formation of a suspension and/or emulsion of nutrient medium and micro-organisms with oil as the external phase. A limiting emulsion may then be formed (5-25 parts of yeast, 75-30 parts of water and 20-45 parts of oil) by removal of large amounts of external oil. Water is removed from the suspension/ emulsion or limiting emulsion, by evaporation or by the addition of a hydrophilic organic solvent or readily soluble salt. According to an example, 68À4 g. of the light phase of a run-off of the aerobic fermentation of diesel oil with a yeast of the species Candida lipolytica are subjected for 10 minutes to a centrifugal field of 5À5 x 10<SP>3</SP> g. 26À3% of the water thereby separates and is removed. The product thus obtained is stirred in a glass beaker, whereby oil separates. 88À5% of the oil originally present in the light phase can be separated. The pasty residue (about 20 g.) is subjected to a vacuum distillation in a rotation evaporator at a pressure of 100 mm. Hg. 13 g. of distillate pass over. The yeast is obtained as a dry, oil-containing product suitable for de-oiling in known manner.

Abstract: 955,184. Knitting-machines; turning inside out. SCHUBERT & SALZER MASCHINENFABRIK A.G. Nov. 29,1961 [March 15, 1961], No. 42633/61. Headings D1C and D1X. A pneumatic fabric take-up arrangement for a circular machine comprises sucking or blowing the fabric upwardly through a tube 1 positioned above the needle cylinder. This ensures that the fabric tube or stocking is turned inside out whereby subsequently loose ends of yarn can be trimmed. In the case of the fabric being withdrawn by sucking, the upper end of the needle cylinder is closed by a guiding cone 2. The tube 1 constitutes the drive to the transfer dial 9 and its lower end is shaped as at 12 to provide a space 2<SP>1</SP> between itself and the cone 2 through which the fabric is drawn away from the needles prior to being turned inside out as it is drawn up into the tube ,1. Alternatively the upper end of the cylinder may have a nozzle 21, Fig. 2, through which air is blown to draw the fabric from the needles and blow it up into the tube 1. To enable the transfer dial to be pivotably raised a slidable connecting tube 15 is provided which normally connects the upper end of tube 1 with a tube 16 communicating with a blower and a receptacle for receiving the completed stocking. When the tube 15 is raised as shown in Fig. 3a, the transfer dial can pivot upwardly to an inoperative position. The conduit 16 can be common to a number of machines connecting them to a receptacle for receiving the completed stockings, and a single blower may supply a flow of air to a number of machines. Italian Specifications 556,014, 558,876 and French Specification 1,222,893 are referred to.

Title: Crystalline polymers and process for their preparation
IPC: C08F279/02
Filed: 1962-11-13
Abstract: Solid crystalline polymers containing polymerized propylene and one or more polymerized diolefinic or acetylenic hydrocarbons are prepared in the presence of a solid stereospecific catalyst by initially polymerizing propylene or at least one diolefinic or acetylenic hydrocarbon and thereafter polymerizing the remaining monomer or monomers in the presence of the preformed polymer to obtain a solid crystalline product preferably containing from 80 to 99.9 weight per cent of polymerized propylene segments. Preferably the polymers have an inherent viscosity in tetralin at 145 DEG  C. of at least 0.4 and a density of at least 0.85.  The multi-stage polymerization can be carried out in a single reactor having separate reaction zones, or in separate reactors or in an elongated tubular reactor.  Preferably, propylene is the monomer polymerized in the first stage. Monomers listed in the Specification are 1,3-butadiene; isoprene; 2-ethyl-1,3-butadiene; 2,3 - dimethylbutadiene; 1,1,4,4 - tetramethyl butadiene; piperylene; hexadiene; heptadiene; acetylene; methylacetylene; ethylacetylene; propylacetylene and butylacetylene. The stereospecific polymerization catalysts are initially mixtures of at least two components, component (1) being a transition metal halide and component (2) being a Group Ia or II metal or aluminium, or an alloy of metals of Group Ia and/or II and/or aluminium, or a halide, hydride or organometallic compound of a metal of Group Ia or II and/or aluminium, or a complex hydride or a complex organometallic compound of boron or aluminium and a metal of Group Ia or II.  Lists of suitable catalyst components are given.  In addition, a third catalyst component may be added, e.g. halides of alkali metals, magnesium oxide, aromatic ethers, e.g. diphenyl ether, hydrides of sodium, potassium or lithium, or alcoholates of sodium, potassium, lithium, calcium, magnesium, barium, strontium, aluminium, titanium or zirconium.  When alkylaluminium halides are used, the third component is preferably a tertiary amine or a tris-N,N-dialkyl phosphoramide. Pressures from atmosphere to 2000 atmospheres or more may be employed. In the examples, propylene is polymerized with isoprene, acetylene, butadiene, piperylene, acetylene and methylacetylene, and the catalysts used are (1) LiAlH4+TiCl3, (2) Li+TiCl3+ diphenyl ether, (3) Li+LiAlH4+TiCl3+NaF, (4) Et3Al2Cl3+TiCl3+MgO, (5) Et3Al+ VCl3+ Al(OPr)3, (6) Et3Al2Cl3+TiCl3+ ((CH3)2N)3P= O, (7) AlEt3+TiCl4, and (8) LiAlH4+TiCl3+ NaF.  The polymers may be used in moulding, film and fibre applications. Antioxidants (e.g. a mixture of dilauryl thiodipropionate with 4 : 41 - butylidene - bis - (6 - tert. butyl-m-cresol) or n-butyl-hydroxytoluene), slip-agents, antiblock agents, pigments, extenders &c. may be added to the polymers.

Filed: 1974-10-03
Abstract: 1481874 Television INTERNATIONAL STANDARD ELECTRIC CORP 3 Oct 1974 [8 Oct 1973] 42946/74 Heading H4F Additional digital signals, e.g. further sound signals or other data signals, are transmitted during the back porch periods after the colour bursts of a colour television signal, the pulse repetition frequency of the digital signals being equal to at least the second multiple of the colour sub-carrier (i.e. burst) frequency with a start pulse preceding the first pulse of the digital signals. The duration of the horizontal sync pulses are shortened to accommodate the digital signals on the back porch, and the amplitude of the digital signals is arranged to be above the maximum level of the colour bursts. In the transmitter the digital signals are entered and removed from a shift register under the control of a pulse generator itself controlled by the colour sub-carrier frequency, the digital signals being produced by one or more analogue-todigital converters, e.g. from one or more sound signals. In the receiver a similar shift register is employed in the digital signal responsive equipment which is activated by the detected leading edge of each horizontal sync. pulse and the start pulses.

Abstract: 1326632 Slack adjusters KNORR-BREMSE GmbH 9 Sept 1970 [9 Sept 1969] 43254/70 Heading F2E A floating caliper spot-type disc brake has hydraulic and mechanical actuation the mechanical actuator being provided with automatic adjustment and comprising a spindle 10 having a screw threaded connection 12 with a sleeve 13, keyed at 14 for axial but non-rotatable movement, which abuts at 19 with a sleeve 17 having a screw threaded connection 18, of opposite hand with a caliper 4, sleeve 17 carrying ratchet teeth 20 which engage with a pawl 22 pivoted at 21 to an operating lever 9 rigidly connected to screw threaded spindle 10. When lever 9 is turned in the direction of arrow 23 spindle 10 is axially displaced by means of screw thread 12 so that a pressure pin 11 exerts pressure on a brake pad. If wear occurs in the pad the extra movement of lever 9 necessary to compensate for this causes pawl 22 to ride along the back of one tooth of toothing 20 and on to the back of another so that on release of lever 9 the sleeve 17 is turned in threaded connection 18 so that the abutment at 19 causes compensation of the wear. Pawl 22 may have a slot 24, Fig. 4 (not shown) in which a spring (27) loading a pressure member 26 is located so that only during the initial part of the release operation does pin 21 entrain pawl 22 but during the remaining part spring (27) causes member 26 to abut pin 21 at the side adjacent the tooth engaging surface (25) of the pawl 22 thereby initialling displacing pin 21 in slot (24). Thus at the beginning of the release pawl 22 retains its position relative to caliper 4 with the result that spindle 10 is screwed in the release direction while sleeve 17 is still stationary. In a further embodiment Figs. 5, 6 (not shown) The pawl (22<SP>1</SP>) is provided in a recess (28) of lever 9 which in section diverges towards the brake disc, the pawl (22<SP>1</SP>) carrying a bevelled member (36) engaging in a slot (35) of the ratchet provided on sleeve (17<SP>1</SP>). On operation of lever 9 the pawl (22<SP>1</SP>) pivots in the recess 28 and if wear is excessive, engages a wall 29 thereof causing bevel 36 to slide over the slot into another so that on release the lever sleeve (17<SP>1</SP>) moves axially to provide the adjustment.
