Title: Motion Picture Projector
IPC: G03B1/50
Filed: 1966-09-28
Abstract: 1,165,952. Cine projectors. BELL & HOWELL CO. Sept. 28, 1966 [Oct. 19, 1965], No. 43349/66. Heading G2E. A sprocketless cine projector for use with standard 8 mm or super 8 mm film has a shuttle mechanism whose teeth 46 are spaced apart by a distance which is a whole number of perforations on one film and a different whole number of perforations, not a multiple of the first, on the other film. The stroke length of the shuttle is manually variable to suit the film by means of linkage 90 which shifts the pivot 92 of shuttle drive member 70 from point 72a to point 72b. Cam surface 76 engages flats 106 of member 70 to give a vertical reciprocation of shaft 82 which is transmitted to the shuttle through lugs 84. Face cam 86 pivots the shuttle about its shaft 82 by engagning shoe 106. The gate apertures 54a, 54b are simultaneously interchanged by linkage 90 as the shuttle stroke is changed. Aperture plate assembly 26 is slidable vertically and slightly sideways on guide pins 96 and is locked in either position by the entry of pin 100 on pivoting lens gate 20 into holes 102a or 102b. Pressure plate 24 is carried on gate 20. The shuttle cam is mounted on shaft 78 of apertured disc shutter 52.

Abstract: 1316024 Moulding expanded plastics KOPPERS CO Inc 22 Sept 1971 [21 Jan 1971] 44293/71 Heading B5A Articles are moulded by expanding thermoplastics particles by the application of heat and vacuum in a mould comprising two sections each having (a) a removable inner shell or lining 25 which is removable and replaceable by one of a different shape, (b) an intermediate shell 27 defining with the inner shell a first chest 33 through which heating and cooling media are circulated, and (c) an outer shell 29 defining with the intermediate shell a second chest 35 connected by a passageway to the mould cavity 31 and also connected to sources of vacuum for expanding the particles and of air for expelling the articles after cooling. In the embodiment the shells of each mould half 13, 15 are bolted together and sealed by gaskets 39, 43 and 49. The mould halves are connected by members 19 to a cylinder 21 for opening and closing the mould. Partly expanded polystyrene particles are introduced into mould cavity 31 through means 133 screwed through the three mould shells. Steam for heating and water for cooling enter the first chest 33 through nipples 101 which are threaded through the outer shell 29 and into the apertured boss 97 of intermediate shell 27 and are sealed with gaskets 109, 111. Alternatively (Fig. 3, not shown) the steam and water nipples may be threaded through the part of the intermediate shell 27 which is not overlayed by the outer shell 29. The air and vacuum are supplied to the second chest 35 by similar nipples 121. The passageway between the second chest 35 and the cavity 31 comprises an axial bore 83 communicating with a transverse bore 85 in a bolt 71 which passes through and is sealed at 89 to the outer shell 29. The end of bolt 71 is screwed into an apertured boss 55 in the inner shell 25 and plastics material is prevented from entering the aperture by a perforated screen 93. Alternatively (Fig. 4, not shown) the passageway may be formed by a hollow bolt.passing through apertured boss of the inner shell and screwed into the intermediate shell 27.

The MM 4550 is produced by cultivation of a MM 4550 producing strain of Streptomyces olivaceous, e.g. ATCC 21379, ATCC 21380, ATCC 21381, or ATCC 21382, or a mutant strain thereof in a nutrient medium containing assimilable sources of carbon, nitrogen and mineral salts, and thereafter recovering MM 4550 from the mixture. The cultivation is preferably carried out aerobically at 20-35‹ C., in a nutrient medium at approximately pH 7. The nutrient medium may contain yeast extract, soyabean flour, meat extract, cottonseed flour, malt, amino acids, distillers dried solubles, protein hydrolysates, and inorganic nitrogen in the form of ammonium or nitrate ions. Suitable carbon sources are glucose, lactose, maltose, starch and glycerol. The MM 4550 may be recovered from the medium by ion-exchange methods, chromatography or gel filtration. The yield may be increased by the inclusion in the growth medium of manganese sulphate, cobalt chloride or calcium carbonate. Antibacterial synergism between MM 4550 and penicillins or cephalosporins has been observed.

Abstract: In preparing paper pulp, a fraction comprising particles with a major dimension of 5 m  or less is separated from an aqueous dispersion of the fibres and dried under agglomeration to form particles having a major dimension exceeding 5 pc and preferably between 50 and 100 m , with the dispersion before separation, or the remaining part of the dispersion after separation with or without the agglomerated particles being formed into paper pulp. The fraction is dried by atomizing the suspension, which may be pre-concentrated, in a drying chamber, with the particles in any drop adhering to one another by means of the natural resins in wood pulp, or if the pulp is formed from straw, or rags of wool and cotton, by means of an added resin or other adhesive.  The agglomerated particles may be returned to the same or different dispersions, while in the latter case different border lines may be used in the fractionating.
