Title: Improved process for recovering protein from whey
Inventor: HULL MAURICE EVERETT
IPC: A23J1/20
Filed: 1951-12-19
Abstract: Protein is obtained from whey by adjusting the pH of the whey to 7.0-8.3, heating to 180-212 DEG F., agitating and adjusting the pH to 4.1-4.5 to coalesce the protein; and separating the whey from the protein.  The whey may be sweet or sour and is preferably adjusted initially to a pH of 7.3.  Proteins are preferably removed from the whey before the latter is drawn off and may after filtering from surplus liquid be stood overnight and pressed in a cheese press. When small quantities of whey are treated the coalesed proteins may settle to the bottom in which case the supernatant whey may be removed by decantation.  Sodium and potassium hydroxides are preferred for neutralisation, other bases mentioned being ammonium hydroxide and soluble bicarbonates, carbonates or alkaline phosphates.  Alkalis of low salt content are preferred.  Acidity is preferably adjusted with hydrochlric acid, other acids mentioned being acetic, phosphoric, sulphuric and edible water-soluble organic acids.  Heat and agitation may be obtained from steam jets.

Filed: 1965-07-14
Abstract: 1,123,193. Measuring circuit characteristics. MULLARD Ltd. 6 May, 1966 [14 July, 1965], No. 29848/65. Heading G4H. In apparatus for measuring the electrical transfer characteristic of a circuit in a desired frequency band, input pulses having an energy spectrum including said band are generated repetitively and applied to said circuit, the waveforms of the input pulses and output pulses from said circuit being approximately reconstituted on an extended time scale by sampling successive input and output pulses, the samples then being digitized. Thus the samples required at successive points within the typical input (or output) pulse are obtained from respective successive (identical) versions of the pulse. The digitized samples are used by a computer for Fourier analysing the input and output pulses to derive their amplitude and phase components, the ratio of respective amplitudes (input and output) and the difference of respective phases being obtained. The group time delay (rate of change of phase with frequency) can also be calculated.

[Class 107] A road-making machine comprises a caterpillar tractor 1 and a hooded frame 2 containing a series of soil cutting and blending tools. The frame pivots about an axis 76 situated at one end of bell-crank levers 38, which are themselves turned about a fixed axis 43 on the tractor by hydraulic jacks 45. The frame 2 can be turned about the axis 76 by hydraulic jacks 74 acting on bell-crank levers 72, and it supports shafts 90, 103, 108 and 109. The shaft 90 carries cutting blades 96 which on rotating at a high speed disintegrate the soil and throw it against impeller blades 107 mounted on the shaft 103. The soil is tossed to and fro between the blades 96 and 107 causing further disintegration until finally the soil is thrown to the mixing blades 112. In passing from the blades 107 to the blades 112 the soil passes through a spray of bonding material issuing from pipes 169, 178. The soil and the bonding material are thoroughly mixed in the intermeshing zone of the blades 112 before the mixture is ejected from the mixing blades on to the ground ready for rolling. The bonding material is supplied from tanks 4 mounted on the tractor by either a centrifugal pump 150 or a positive displacement pump 148, the power for the drives to the tracks, the shafts and the pumps being supplied from an engine 10.

Abstract: 1,111,572. Electrostatic precipitators. W. KUSTERS. 4 July, 1966 [9 July, 1965], No. 30030/66. Heading B2J. Apparatus for cleaning flue gases comprises a shell 11 contains an outer cylindrical electrode 12 and an inner corona discharge electrode 13. A horizontally curved deflecting shield 22 at one end of the outer electrode deflect gases emerging from the inner space in proximity with the outer electrode into a space between the outer electrode and the container shell. Flue gases are swirled by deflector blades or by introducing the gas tangentially and enters by a duct 15. The flue gases are constricted by a nozzle 19, which produces a pressure reduction at 20. Charged material is drawn up at 21 close to an unperforated outer electrode 12 and deflected by the toroidal shield 22 downwards into pockets 18 because of the pressure reduction at 20, from whence they are removed.

Abstract: 1376640 Semi-conductor devices WESTERN ELECTRIC CO Inc 27 June 1972 [28 June 1971 (2)] 30046/72 Heading H1K A charge coupled device comprises an electrode arrangement, on an insulating layer, over a charge carrier storage medium, fixed charges being distributed beneath the electrode arrangement to form an asymmetric well during operation. The fixed charge may reside in the medium, the insulating layer or both, and may be produced by diffusion or ion implantation. In one embodiment, Figs. 1, 2 (not shown), a two-phase system has chargers fixed in the medium and distributed non-uniformly so as to form potential barriers to charge carriers in the "upstream" direction.  In a second embodiment, Fig. 6, the fixed charges reside, non-uniformly, in the insulating layer, again forming potential barriers in the "upstream" direction. The use of two value clock pulses enables a single row of electrodes to be used, the first pulse to all electrodes being of a low value to form shallow potential wells beneath the electrodes enabling carriers to transfer to deeper wells beneath the interelectrode spaces, the second pulse being of a greater value to form deep wells beneath the electrodes and receive carriers, in one direction only, from the shallower inter-electrode wells. In a further embodiment, the electrodes may be mounted on insulating material of irregular thickness to assist in the formation of suitably asymmetric wells. In Fig. 12 (not shown), a single electrode extends over insulating material of irregular thickness, the material containing a non-uniform distribution of fixed charge, a two-value clock pulse enabling charge transfer by means of wells of different depths beneath different parts of the electrode. The medium may be of silicon, the insulating layer of silicon dioxide.

Abstract: 778,859. Purifying liquids. PERMUTIT CO., Ltd. Oct. 20, 1955 [Oct. 20, 1954], No. 30258/54. Class 46. The passage of liquid vertically through a bed of granular material such as ion-exchange material or activated carbon to purify the liquid or to regenerate or wash the material is interrupted from time to time, a liquid is introduced at one end of the bed-container to move the bed vertically as a whole, thereby leaving a space at the one end and expelling material at the other end, and fresh material is introduced into the space. Liquid to be treated is introduced at 6, Fig. 1, and treated liquid passes out at 8. When partially-treated liquid withdrawn as a sample at 35 indicates deterioration in the liquid condition the valves on 6 and 8 are closed. Thereupon liquid is introduced at 20 and drives the bed 4 before it, granular material being expelled through a now-open valve 22 and the driving liquid passing out through a ring of holes 14 and valve 18, opened at the same time as 22. After discharge of the top layer of the bed the valve controlling 20 and valve 22 are shut and fresh granular material is introduced at 24, displacing the liquid filling the granule-free space below the bed through the valve 18. The treatment process is then restarted. In Fig. 2 features 6, 8 and 20 are as before, but in this case the liquid introduced to move the bed carries the bed bodily with it and passes out with the expelled granular material at 22 so that features 14, 16 and 18 may be dispensed with. Fresh granular material is in this case introduced at 30 through a ring of holes 26, the displaced liquid passing out at 22. In either case the collecting device 8 may be at the bottom of the container. In Fig. 3 the liquid to be treated passes upwards from inlet 6 to outlet 8. Liquid for moving the bed downwards is introduced at 20 through pipe 10 and withdrawn at 8 ; expelled granular material passes out at 22. Fresh granular material is introduced at 24 and displaces the liquid filling the granulefree space above the bed through 20 and an outlet 38. In all cases the distribution device 20 may also act as the collecting device on the outlet 8, -appropriate connections being provided outside the bed. According to the Provisional Specification the outlet 22 in Figs. 1 and 2 may be replaced by a discharge pipe with an open mouth in the top of the bed, the pipe extending downwards from its mouth and outwards through the container wall.
