Inventor: OTTOFRICKENSTEIN HANS
IPC: C12M1/40
Filed: 1984-02-17
Abstract: A process and reactor are disclosed for the continuous treatment of a turbid liquid with a granular treating agent placed in a fixed bed through which the liquid flows. Preferably, the liquid is whey and the treating agent is lactase immobilized on support particles, and treatment involves hydrolysis of lactose in the whey. During treatment, the flow of whey through the fixed bed is periodically interrupted and a flow of cleansing liquid is passed through the fixed bed countercurrent to the flow of whey. The flow of cleansing liquid is under sufficient hydrostatic pressure to press the fixed bed against moving fragmentation devices to separate and fluidize the support particles into a fluidized bed whereby the support particles containing immobilized lactase are cleansed by removing material deposited thereon from the whey.

Title: Polymerization process
Inventor: FILIPPELLI MICHEL C H
IPC: C08F2/34
Filed: 1994-05-19
Granted: 1999-01-31
Abstract: The invention relates to continuous gas fluidised bed polymerisation of olefins, especially ethylene, propylene, or mixtures of these with other alpha olefins, wherein the monomer-containing recycle gas employed to fluidise the bed is cooled to condense out at least some liquid hydrocarbon. The condensed liquid, which can be a monomer or an inert liquid, is separated from the recycle gas and is introduced directly to the bed to produce cooling by latent heat of evaporation. The liquid is introduced directly into the bed using injection means. The process provides substantially improved productivity of gas fluidised bed polymerisation of olefins. <IMAGE>

Abstract: 903,050. Colour separation records for multicolour reproduction. AGFA A.G. Jan. 1, 1959 [Jan. 3, 1958], No. 104/59. Class 98 (2). An uncorrected colour separation record and a mask corrected for colour value are prepared directly from the same colour original in two light-sensitive layers on separate supports and are combined to produce an improved colour separation record suitable for printing through, either or both of the light-sensitive layers containing (i) a coloured coupler which recouples to give another colour or becomes colourless in colour development or (ii) a colourless (or nearly colourless) coupler which is coloured automatically at the uncoupled areas during or after colour development. The first-formed record and the mask normally differ in colour as by use of black and monochromatic images, respectively, thus in an example three continuous-tone colour separation records are made from the original using blue, green and red filters on panchromatic material containing the coupler of Example 25 of Specification 866,203 and developed to black and white, second green and red filter records produced under the same conditions are re-exposed and colour developed to yellow; pairs are then combined (a) blue filter black and white with green filter yellow coupled, (b) green filter black and white with red filter yellow coupled, and (c) red filter black and white with the same red filter yellow coupled, and are printed through to form colourcorrected blue, green and red records, respectively, contrasts and gradations of the intermediate records being specified. Other procedures indicated include diazo coupling of uncoloured residues of colourless couplers after colour development. Specifications 599,377, 617,247, 690,997 and 739,202 also are referred to.

IPC: G01S7/22
Filed: 1947-01-09
Abstract: 643,663. Radiolocation. ELECTRIC & MUSICAL INDUSTRIES, Ltd. Jan. 9, 1947, No. 717. [Class 40 (vii)] In radio range-finding apparatus of the type employing a cathode-ray tube display in which a trace moves angularly in synchronism with an aerial and reflected signals from objects modulate the tube beam, the beam is further modulated to produce a range scale occupying a small angle compared with that through which the trace moves and adjustable in angular position. In a plan-position display apparatus, Fig. 1, two pulse generators 22, 23 are connected to modulate the grid of tube 21 for short periods during each rotation of the trace by means of spring fingers 11, 12, 13 engaging contact members 3, 4, 5 carried by a shaft 1 rotating in synchronism with the aerial. Contact member 3 encircles the shaft and portions 4 and 5 are arcuate pieces of different length whereby generator 22 producing, say, 5000-yard marker pulses is connected to the tube grid for a longer period than generator 21 producing, say, 1000-yard marker pulses. The two generators are synchronized with the radial sweep and produce a range scale occupying about 5 degrees of arc, as shown in Fig. 3. Lines 27 are the 5000-yard marks and lines 28 the shorter 1000-yard marks. Spot 29 represents a typical target. To adjust the angular position of the scale, fingers 11, 12, 13 are rotated around shaft 1 and for this purpose are carried by an insulating collar 6 and connected through sliprings 15, 16, 17. Collar 6 has peripheral teeth engaging gear-wheel 24 provided with a handle 25. More than two generators may be employed. As an alternative, the generators may be connected continuously to the cathode-ray tube and may be rendered operative at the appropriate times by switches closed for a short period during each rotation of shaft 1.

Abstract: 1,049,841. Automatic exchanges. STANDARD TELEPHONES & CABLES Ltd. Jan. 8, 1965 [Jan. 15, 1964], No. 959/65. Heading H4K. [Also in Division G4] An allotter comprises a ring counter provided with means for indicating failure if its stepping rate departs by more than a predetermined amount from standard. The first and last stages of a group 1-6 open an AND gate 72 if they operate at the required rate, and so also for other groups and AND gates 73-75. AND gates 72, 73 and AND gates 74, 75 are likewise coupled to turn flipflop 81 alternately on and off. Correct operation marks lead 85 but failure energizes inverter 86 to bring up an alarm and switch in a stand-by allotter 63. The allotter may assign groups of circuits for service (Fig. 3, not shown) each group having a predetermined or a random order of preference. Any circuit which is already busy is automatically excluded. A test is made as to whether the calling subscriber is permitted the class of service demanded before a circuit is finally assigned. If the selected circuit in a group is faulty the primary allotter steps to the next group. Distribution of service is therefore improved and a faulty circuit in one group disables a limited amount of equipment. Preference in a group may be determined by stepped decrements of potential at the base of each NPN transistor round the ring from a conducting transistor (Fig. 7, not shown).
