Abstract: 1,219,466. Extracting fats. E. LEVIN. 23 May, 1968 [23 May, 1967], No. 24756/68. Heading C5C. A process of removing fat and water from biological material, e.g. fish, meat or coconut, to produce a nutritious solid residue comprises providing within a distillation vessel an azeotrope-forming zone containing a fat solvent which forms with water an azeotrope having a b.p. materially lower than the b.p. of the solvent, introducing comminuted biological material into the solvent to form a slurry, heating solvent to form hot solvent vapour and introducing the vapour below the surface of the slurry which is kept at a temperature well below the condensing temperature of solvent by evaporation from the slurry of the low boiling azeotrope, boiling off the azeotrope using the heat of condensation of the solvent vapour collecting and condensing the azeotrope and recovering from the azeotropeforming zone a defatted and dehydrated solid residue. Preferred non-polar solvents are pentane, hexane, heptane, benzene, toluene and cyclohexane. Polar solvents which may be used as ethylene dichloride, propylene dichloride and perchlorethylene.

Title: Production of polycarbonates
IPC: B29C48/76
Filed: 1959-07-24
Abstract: Solid polycarbonate is recovered from solution in an inert solvent by heating the solution to volatilize solvent therefrom whilst retaining sufficient solvent with the polycarbonate-solvent mixture to keep the mixture liquid until a temperature at which the polycarbonate is flowable is reached and thereafter extruding the polycarbonate substantially free from solvent.  The solution may be that obtained by phosgenation of a dihydric phenol, possibly in admixture with an aliphalic or cycloaliphalic dihydric alcohol, in a heterogenous liquid reaction medium in which one phase is an organic solvent such as a chlorinated aliphatic compound, dioxane, tetrahydrofurane, acetone, isobutyl ketone, benzene or toluene.  In an example, a methylene chloride solution of a bisphenol-A polycarbonate is fed to an elongated heated chamber provided with twin screws and which terminates in an extrusion die.  At the middle of the chamber, about 95% of the methylene chloride is removed in vapour form, and at point beyond this the balance of the methylene chloride is removed under vacuum.  Finally, when the polycarbonate in the chamber is at about 288 DEG C., it is extruded through the die into spaghetti like rods which are chopped into granular particles.  Specification 772 627 is referred to.

[Class 138 (ii).] In an ironing-machine wherein padded rollers 3, Fig. 2, coact with concave beds, the endless tapes 6 that prevent the articles being ironed from adhering to the rollers are formed of the same fabric material as the cover cloth of the padding on the rollers and the longitudinal edges of the tapes are frayed for an appreciable width as at 8, Fig. 3, so that no impressions of the tapes are left upon the articles being ironed. The return flights of the tapes are guided over pulleys 32, Fig. 2, yieldingly supported at the front of the machine and formed with concave peripheral grooves whereby folding of the frayed tapes is prevented. The pressure side bars 4 are connected by a shaft 13 on which heavy wire supporting members 18 for the pulleys 32 are loosely mounted, each supporting member comprising two eye portions 19, 20, Fig. 3, engaging the shaft 13 and bridged by a member 21. A spring 23 is anchored at one end 22 to the bridge member and at the other end 24 to the shaft 13 whereby longitudinal movement of the supporting member in one direction is prevented. Movement of the supporting members in the other direction is prevented by pins 27. Pins 34 prevent the pulleys 32 from leaving the ends 30 of the supporting members 18.

Equipment for producing predominantly scotopic vision in one eye, and predominantly photopic vision in the other eye respectively comprises two devices, the first of which comprises a filter passing predominantly red light of wavelength beyond 6000A combined with a neutral density filter having a transmittance of 25-75%, and the second of which comprises a colour filter having a band-pass range (70% of peak) lying within the range 4800-7300A. The red filter preferably also passes blue light of up to 25% of total in the range 4000  to 4750 . The arrangement utilizes the difference in time responses of the eye in the two types of vision to enhance the stereoscopic effect noticeable in an ordinary moving picture due to the relative motions of images therein. The two devices may be mounted in a spectacle frame preferably of the type which may be inverted to allow the wearer to inter-change the devices periodically to avoid fatigue. Alternatively the device may be in the form of lenticular or line screens containing suitable pairs of devices can be placed over a television or projection screen. Periodic movement of the screen may be used to alternate the types of vision experienced by the respective eyes. In the case of static scenes improved results are stated to be obtained by introducing a small panning effect whilst taking the pictures.

Abstract: 1311903 Exposure control devices EASTMAN KODAK CO 29 May 1970 [29 May 1969] 26024/70 Heading G2A An exposure control device has a photo-cell 28 for receiving scene illumination, a source of alternating voltage, and lamps 32, 34 for indicating whether the intensity of illumination from the scene is suitable to effect a satisfactory exposure of film in the camera. A motion picture camera has a film advancing motor 4 driven by a D.C. source 2 via the primary 6 of a transformer, the D.C. pulses therethrough generating an A.C. voltage across the secondary 8. A lamp 20 is lit if the battery voltage is above a predetermined value as set by variable resistor 22. The A.C. voltage fed to the controlling and indicating circuit is adjusted by tapping 10 according to the film sensitivity. A variable autotransformer 24 is set according to the frame frequency by a tap 25, the output of the autotransformer being fed via diode 30, to a meter 26 operatively coupled to the camera diaphragm. In series with the autotransformer is photo-resistor 28. Lamp 32 is lit when scene illumination is insufficient for proper exposure, and lamp 34 is lit if an overexposure would occur with the existing camera settings. In modifications, autotransformer is replaced by a variable transformer, Fig.2, (not shown); the number of turns in primary 6 can be adjusted, the ignition levels of lamps 32, 34 are adjusted by a variable tap in the secondary and by neutral density filters positioned in front of the photo-cell, Fig.3, (not shown); a second photocell is included so that the first responds to illumination from the central portion of the scene and the second responds to the background portion and the arrangement is such that the first photocell effects the response of the controlling and indicating circuit to a greater degree that the second photo-cell, Fig.4, (not shown); the circuit is simplified so that only one indicator lamp is provided which is lit whenever over- or underexposure would result, Fig.6, (not shown). The warning lamps may be situated behind translucent display panels in the camera view-finder.
