Abstract: 1295232 Nisin production KUTNOWSKIE ZAKLADY FARMACEUTYCZNE "POLFA" 8 Jan 1970 [17 Jan 1970] 1056/70 Heading C2A Nisin concentrate is produced from fermentation wort obtained by fermenting a milk protein-containing nutrient medium with a nisinproducing strain of Streptococcus lactis, by acidifying the wort to pH 3À3-3À7, heating the acidified wort to 60‹ to 120‹ C. to precipitate protein, cooling and filtering off the precipitate, foaming the filtrate, separating the foam and liquefying it, and salting out the liquid to precipitate a nisin concentrate which is recovered and dried. The protein precipitate may be extracted with the spent wort left behind when the foam is separated, to give a nisin-containing extract which is re-cycled in the foaming procedure to provide further nisin concentrate. The resulting second batch of spent wort may then be used to extract further protein precipitate. Several repetitions of the foaming are preferably performed on liquid from which a previous foam has been separated, to leave a final spent wort containing less than 40 Reading units of nisin per ml. The foaming may be performed by continuously feeding the liquid and air, in 6 : 1 ratio by volume, into a high speed pump. The foam is preferably then dried by allowing it to settle in a tank with a bottom outlet for draining off liquid. The foam is then liquefied by sucking it into a funnel so that the changing flow rate on passage through the funnel causes the foam to collapse into a liquid. Sodium chloride is added to the liquid preferably at pH 3.5, to salt out the nisin concentrate. The precipitate is collected and dried with acetone at below 0‹ C. to give a nisin concentrate which has a potency of more than 8 x 10<SP>6</SP> Reading units per gram.

Abstract: 1327375 Dispersions of oleophilic graphite and metal sulphides BRITISH PETROLEUM CO Ltd 31 July 1970 [19 Aug 1969] 41242/69 Heading C1A [Also in Division C5] A dispersion of oleophilic graphite or metallic sulphide in an organic liquid is obtained by grinding a natural or synthetic graphite or a metal sulphide in an agitator mill, i.e. a mill in which grinding is accomplished by agitating a particulate grinding medium by the rotation of an axis having projections attached thereto, under the surface of an organic liquid. The grinding is preferably carried out in the substantial absence of air or oxygen, e.g. the mill is completely filled with the organic liquid during grinding. The grinding medium may be steel balls having, e.g. a diameter less than 5 mm., and the organic liquid may be a lubricating base oil preferably mixed with a diluent organic liquid of less viscosity. This latter liquid may be a paraffinic hydrocarbon boiling below 100‹ C. During grinding the viscosity of the mixture is maintained at a value of 85 to 1000 ep at 25‹ C. measured at a particular shear rate. The dispersion may be continuously circulated through the grinding mill during grinding. The mill may be heated and further organic liquid may be added to the mill during grinding. The graphite or metal sulphate may be obtained by removing the grinding liquid. Greases may be formed from these dispersions of oleophilic graphite and sulphide when lubricating oil is used as the grinding liquid. The mill may be heated during grinding and the product subsequently cooled to form a grease or when a diluent liquid is added to the lubricant oil during grinding, the grease is formed when the diluent is subsequently removed, e.g. by evaporation. An olefine polymer, e.g. high density polyethylene or atactic polypropylene, may be added to the grinding liquid. If desired a plurality of agitator mills are used and the dispersion passed through them in series. The metal sulphide may be Mo, Sn, Pb, or W sulphide.

Abstract: 1347265 Bar feed GKN MACHINERY Ltd 13 March 1972 [12 March 1971] 6769/71 Heading B3B Bar feeding apparatus comprises a body, guide means defining a feed passageway, a pusher 14 for advancing the bars, a driving mechanism external to the guide means and connected to or co-operatively engaged with the pusher for moving the latter along the guide means, the pusher consisting of a rearward part 16 connected or co-operatively engaged with the driving mechanism, and a forward part 17 rotatably mounted on the rearward part by at least one bearing 27 and wherein the pusher has a lubrication duct 41 having an inlet in said rearward part and one or more outlets 46 positioned for distributing lubricant to the bearing or bearings. The rearward part of the pusher comprises three body sections 31, 32 and 33. The forward part has a collet 18 and a mounting tube 29 which abuts a thrust bearing 30. The guide means comprises a feed tube 10 which is split into a lid portion 11 and a lower portion 12 which are hingedly connected together so that the lid portion can be raised to open the feed tube and admits a bar thereto. Drive to the pusher is via a blade which extends through a gap between lid 11 and trough 12. An ejector mechanism consists of an ejector pin 34, an ejector tube 35, a sleeve 36 and a rod 37 biased by a spring 39 such that the ejector pin is normally in a retracted position as shown. When the pusher is moved rearwardly to withdraw a bar stub from the associated machine tail block 38 strikes stop 40 thus halting rearward movement of the ejector mechanism whilst allowing further such movement of the pusher. Lubricant for the bearings can be introduced manually or automatically through slots 42, 45, to pass along duct 41 to openings 46. Lubricant can also enter the clearance space between the ejector assembly and the body sections 31, 32. There is sufficient clearance between the ejector tube 35 and hollow spindle 26 for lubricant to pass therebetween to the outlets. Relative movement between the pusher and the ejector assembly causes a pumping action to force lubricant to the outlets. If the ejector tube is replaced by a solid rod a lubrication duct is cut at a position indicated by a broken line 47. The lubrication duct thus passes radially inwardly of the thrust bearing 30. The slot forming the duct may have a wider rear portion to form an inlet and/or reservoir. Alternatively the duct may extend between the radially outwardly presented face of this rod and the inner faces of body sections 31, 32. An opening in one of the sections where convenient would serve as an inlet.

The RCS includes a plurality of Code Division Multiple Access (CDMA) modems, one of which provides a global pilot code signal. The modems provide message code signals synchronized to the global pilot signal. Each modem combines an information signal with a message code signal to provide a CDM processed signal. The RCS includes a system channel controller coupled to receive a remote call. An RF transmitter is connected to all of the modems to combine the CDM processed signals with the global pilot code signal to generate a CDM signal. The RF transmitter also modulates a carrier signal with the CDM signal and transmits the modulated carrier signal through an RF communication channel to the SUs. Each SU includes a CDMA modem which is also synchronized to the global pilot signal. The CDMA modem despreads the CDM signal and provides a despread information signal to the user. The system includes a closed loop power control system for maintaining a minimum system transmit power level for the RCS and the SUs, and system capacity management for maintaining a maximum number of active SUs for improved system performance. <IMAGE>
