Title: A method of recovering protein from protein-bearing material
IPC: A23J1/14
Filed: 1949-01-17
Abstract: Protein is recovered from protein-bearing material, the protein being more or less dissolved in a liquid having a suitable pH value, by firstly removing the main part of the undissolved substances in the solution by filtering in a filter apparatus and then by subsequent centrifugal separation in a separator plant, from which the sludge concentrate is wholly or partly returned to the filter apparatus for refiltering.  The centrifugal separation may be carried out in two stages; the sludge concentrate from the first stage being fed to the second stage separator, the sludge concentrate from which is returned to the filter apparatus for refiltering.  The liquid components from the two separating stages may be mixed with each other. Alternatively the liquid component from the second separating stage when less pure than the liquid from the first separating stage, is fed, together with the liquid coming from the filter apparatus to the first separating stage.  The Specification as open to inspection under Sect. 91, comprises also a modification of the method in which a separate or second filter for the sludge concentrate separated out at the centrifugal separation is used, the separation being carried out in one or two stages.  The impurities separated off in this second filter are discharged from the process, while the filtrate is mixed with the liquid from the first filter.  This subject-matter does not appear in the Specification as accepted.

Title: Photographic film developing spools
IPC: G03D13/14
Filed: 1949-01-21
Abstract: 664,162. Photographic, roll-film developing apparatus. GENERAL ANILINE & FILM CORPORATION. Jan. 21, 1949 [Feb. 7, 1948], No. 1777/49. Class 98 (ii). A spool for a photographic film developing tank comprises a pair of relatively rotatable disc members, a continuous spiral groove on the inner face of each disc from the periphery to the centre thereof for guiding the edges of a film, and means in one or both discs for engaging the edge of the film inserted in the groove on relative rotation of the discs in one direction and releasing the engagement on relative rotation in the opposite direction, whereby the film is forced into the grooves between the discs on successive relative rotations of the discs. As shown in Fig. 1, the spool comprises two spirally grooved end discs 11, 111, with axial tubular extensions 16, 20 respectively. The longer extension 16 forms the spool hub, and has on its outer surface a longitudinal groove 17 and circular grooves 18 at right-angles thereto. The shorter extension 20 slides over hub 16 and has longitudinal slots 21 allowing internal ridges 23 to snap into and out of the grooves 18, so adjusting the spool for several widths of film. An internal projection of extension 20 enters groove 17, the extension being narrower than the groove to allow relative rotation of the discs. Each disc has a spiral groove 12, Fig. 2, of which the outer groove wall is thickened at 25 and is, formed on the inside with a recess 26 containing a ball 27. When a film fed through openings 14 into the groove passes recess 26, the ball 27 is moved into a larger part of the recess and permits the film to move into the spool. Should the film move in the opposite direction, ball 27 is moved into the narrower end of the recess and jams the film edge against the next groove wall. By relative movement of the discs in alternate directions, the film is moved step by step into the spool. The ball 27 may be replaced by an elliptical cam pivoted in the cavity or by a spring mounted in the cavity to bear tangentially against the film.

Filed: 1917-02-06
Abstract: 113,131. Nelson, J. Feb. 6, 1917. Mineral and tar oils, purifying.-Hydrocarbon oils or spirits having a. disagreeable odour, a yellowish or reddish brown colour, and a tendency to develop gumminess, and particularly the products obtained by cracking, are purified by treatment with an unsaturated fatty oil such as linseed oil with or without phosphoric acid. The oil may be mixed with linseed oil and the mixture distilled, or the oil may be passed in the form of vapour through a heated chamber containing pumice soaked in linseed oil or through a heated tower down which linseed oil flows. In the latter case, the oil vapours may afterwards be passed through a heated chamber containing phosphoric acid pumice. The oil is freed from water before purification, as by leading its vapours through a drying-agent. The treated oil is further purified by storing over a dilute solution of caustic soda, or by passing its vapours over heated soda lime which may be mixed with coke. The Provisional Specification describes the treatment of oils with syrupy phosphoric acid alone.

IPC: B01L99/00
Filed: 1962-01-18
Abstract: 943,453. Bottling. COMMISSARIAT A L'ENERGIE ATOMIQUE. Jan. 18, 1962 [Jan. 20, 1961], No. 1887/62. Heading B8T. A device for filling or emptying small receptacles 1 comprises two hollow needles 7, 8, a needle carrier block 6, fast with a tap 13 for placing the needle 7 in communication with an aspiration circuit and the needle 8 in communication with a liquid delivery circuit, a stopper extension 5 for providing a fluid-tight seal between the needle carrier block 6 and a stopper 4 in the neck of the receptacle and a rack device 34 for causing the tap and needle carrier unit to move vertically. In order to fill a flask 1, the flask is placed in a support 2 and the tap 13 is lowered with the aid of the rack 34 so that the needle carrier block 6 enters the extension 5 of the stopper 4 which is made of material, e.g. an elastomer, capable of being pierced by the needles and which reseals itself. The needles 7 and 8 pierce the stopper 4 and a grooved member 18, connected to the tap 13 is manually rotated so that passages 10 and 14 are linked to an aspiration circuit and a vacuum is set up in the flask via the needle 7. The member 18 is then rotated so that passages 11 and 15 are joined to a reservoir of liquid which liquid is drawn into the flask through passages 11, 15 and needle 8. By alternating the two positions of the member 18, the flask is filled. The extension 5 may be rinsed out by feeding a rinsing liquid into a union 9 and passages 38, 33 after withdrawing the liquid from the needle 8 and the pipes into the reservoir. The apparatus is turned upside down to empty a flask.

Title: Improvements in, or relating to, closure members for valves or gates
IPC: B65D90/58
Filed: 1935-01-19
Abstract: 441,737. Shoots and hoppers. FLOOD, W. H., 50, Ecclesall Road South, Sheffield. Jan. 19, 1935, No. 1890. [Class 78 (i)] [See also Group XXIX] A valve or gate for controlling the passage of materials of widely differing consistency comprises a flexible closure member or apron 20 which is progressively stripped from the valve seat to open the valve by contact with a supporting roller 10 having a translatory movement across the valve seat, the area of the apron which is in contact with the roller 10 changing progressively but remaining the same in extent. In Fig. 1, the valve seat is formed at the base of a hopper 2 mounted in a frame 3 provided at each side with anti-friction rollers 5 to support a carriage comprising a plate 4 and angle irons 7. The roller 10, two pulleys 13 on a common shaft 12, and a series of intermediate supporting rollers 25 are mounted on this carriage which is reciprocated as a unit by a rack 14 and pinion 15 the shaft of which is operated by a chain and a sprocket wheel. One end of the apron is fixed to a stationary bracket 21 and the other end to two cables passing over the pulleys 13 and connected to adjustable bolts 23. The apron may be of leather or other flexible material or may consist of ropes, metallic chains or small articulated links in which latter case the roller 10 is of polygonal cross-section. To avoid fouling the edge of the valve seat in the final closing movement, an opening may be formed in the seat and the apron and carriage constructed to project beyond the seat so allowing material passing through the opening to rest on the apron at its angle of repose. In a modification the rollers 5 are replaced by suitable wheels, rollers or skids mounted on the carriage for engagement with guideways on the frame 3. In this form, the pulley shaft 12 has eccentric spigots adjustably clamped in the frame for tensioning the apron. In a further modification, Fig. 8, two hoppers 31, 32 are controlled by a single apron 20 so that only one can be opened at once. Both ends of the apron are anchored at 39, 40 intermediate the hoppers. The apron passes over supporting rollers 37, 38 at the ends of a carriage fitted with wheels 33. The sides 42 of the hopper may be of flexible material such as rubber or leather. According to the Provisional Specification, the apron may be of rubberized fabric or balata, and the cables may be dispensed with, an endless belt anchored at one point being used instead.

Abstract: 658,661. Jigging conveyers; discharging material from hoppers. OTTO, C. Jan. 24, 1949, No. 1943. Convention date, Sept. 3, 1948. [Class 78 (i)] [Also in Group XII] The coking chambers of a coke oven battery (see Group XII) are charged three at a time by a travelling lorry 60 which runs on rails 62 on the battery roof and supports a coal hopper 63 which is divided internally into three sections, each holding enough coal to charge one oven. The lorry is moved to the charging position, so that coal outlets 65 register with the charging holes 29 of each oven. Telescopic sleeves 76 are lowered over each hole to prevent hot gases from passing up around the hopper 63, chimneys 77 providing for their escape. The coal is fed from each section to the outlets by a vibratory feeder 64 which is suspended from hopper 63 by links 69 which allow the reciprocatory movement of the feeder. A motor element 69a actuated by alternating current vibrates the feeder through members 71 at a frequency equal to or twice that of the current.

Abstract: 953,383. Control of nuclear reactors. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Jan. 16, 1962 [Jan. 17, 1961], No. 1978/61. Heading G1A. A control system for effecting shut-down of a nuclear reactor in response to excess neutron flux comprises a flux measuring ionisation chamber 2. an A.C. generator 1 to provide polarising potentials for the chamber, a virtual earth integrator which receives the output of the chamber which includes a component of current in-phase with the polarising potential and a component in quadrature therewith, means such as a balance network 3 for feeding to the integrator comparable components of current adjusted so that the integrated in-phase components from the network and the chamber cancel at a value corresponding to a given flux level whilst the integrated quadrature components yield a residual signal at all flux levels, sampling means 5 for sampling the integrator output at given intervals of electrical angle to produce pulses proportional to the current/time integrals of the components and means for applying the pulses to a control element such as a magnetic core element 7 responsive to the sample pulses due to the inphase component of current. In the embodiment shown the sampler 5 samples the integrated output at #/2 intervals of electrical angle and the output pulses from the sampler 5 are fed to a bi-stable circuit 6 which produces a rectangular waveform which is applied to a bias winding W1 of a magnetic core element 7 having a rectangular hysteresis loop. A further wave-form is applied to the winding W1 of the same amplitude as but in anti-phase to the signals from the circuit 6 so that a constant D.C. bias current is produced which provides steady saturation of the core element, at flux levels below the given neutron flux level at which shutdown is required. The winding W1 is thus energised by a constant bias current to provide steady saturation of the core 7. An interrogation winding W2 and a response winding W3 of the core operate such that when an interrogation pulse of proper sign and amplitude is applied to W2 to cause the magnetic flux in the core 7 due to the bias current to reverse, the flux reversal is. detected by winding W3. If no output from the winding W3 is obtained in response to an interrogation pulse this is due to oss of "interlace" between the waveforms fed to W1 as a result of the flux approaching shut-down level or a failure of the circuit applying bias current and a reactor shut-down is initiated by a trip mechanism (not shown). In a further embodiment (Fig. 2 not shown) a double frequency generator and a gate circuit is added to the above.
