IPC: B29C48/67
Abstract: 927,989. Extruding plastic materials. BADISCHE ANILIN- & SODAFABRIK A.G. Feb. 20, 1962 [Feb. 23, 1961], No. 6465/62. Class 87(2). In a process for the continuous homogeneous incorporation of substances, such as colouring matter or stabilizers, which are to be finely dispersed in melts of plastics by premixing a small portion of the powdered or granular plastic with the substance to be finely dispersed therein, the mixture is supplied in the cold state to an extruder 1, the mixture being melted in a melting zone and the melt mixed in a mixing zone adjacent to the melting zone in the extruder 1, mixing the resultant melt in a second mixing zone with the bulk of the plastic introduced in a molten condition and discharging the complete mixture thus obtained from the extruder. The extruder 1 houses a worm screw having a rear part 6 in the melting zone and a front part 7 in the second mixing zone. The melting zone is fed from a rear feed hopper 2, and the second mixing zone by a front feed hopper 3. Immediately prior to the front feed hopper 3 is a flow retarding element 8 which has the same external diameter as the screw thread and forms a narrow gap of 0À01 to 0À2 m.m. between its outer surface and the inner surface of the extruder housing.

Title: Cyclic ketones as perfume components
IPC: C07C45/29
Filed: 1971-05-24
Abstract: Cyclic ketones (I) and (II) are useful as components in perfume mixtures: (where one R = CH3 and the other = H, one Y = O and the other two are pi bonds so that O is bound to one or other of the C atoms to form a carbonyl gp., and the double bond of this grp. is shown by the dotted lined and n = 0 or 1). The cpds. are made by trimerisation of isoprene or piperylene to trimethylcyclododecatrienes, with epoxidation to the corresponding monoepoxides, followed by isomerisation of the epoxy cpds. with acids to the cyclic ketones (I) or (II).

Abstract: A fluidizing centrifugal pump (10) for medium to high consistency fiber suspension includes a housing (14) having an inlet channel (16) and an outlet (18) and an impeller (12) operatively rotatable about the pump axis (34). The impeller (12) has a working vane (36) and at least a blade (40) extending substantially axially from the working vane (36) and disposed in the inlet channel (16) for fluidizing suspension which is received in the pump inlet (16). A feeding (44) vane, preferably in the form of a spiral thread, is disposed in the inlet channel (16), radially-outwardly from the fluidizing blade (40) and extending along at least a portion of the axial extension of the blade (40). The feeding vane (44), which may be operatively rotatable with the impeller (12) or stationarily fixed to the pump housing (14), provides axially-directed feeding of suspension through the inlet channel (16) toward the working vanes (36), concurrent with fluidizing of suspension in the channel (16) by the impeller blade (40), thereby effectively preventing reverse flow of suspension in the inlet channel (16) and correspondingly increasing the operating efficiency of the centrifugal pump (10).
