Title: A method and installation for continuous rearing of yeast
IPC: C12M1/04
Filed: 1950-08-29
Abstract: 683,501. Yeast. STICH, E. Aug. 29, 1950, No. 21298/50. Class 14 (ii). A method for rearing yeast in counter-flow and double circulation consists in taking the mash off each compartment of a common vessel divided into several compartments close to the bottom thereof, after which it is put under pressure outside the vat, cooled while pushed upwards and supplied back to the vat from above, under addition of nutritive solution and led to a distributer from which the mixture of mash and nutritive solution, broken up into jets, is made to act upon the foam produced during the yeasting process, means being provided whereby the mash is compelled to flow from one compartment into the next one in circulation,: the circulating-time of which can be adjusted. As shown several counter-now compartments i<SP>1</SP>, i', i' of a yeasting chamber VH contained in the vat with an ageing-compartment AR, are connected in series in total circulation. Each of the compartments i<SP>1</SP>-i<SP>3</SP> as well as AR possess a counterflow circulation of their own with the pumps b<SP>1</SP>-b<SP>4</SP> and the distributers d<SP>1</SP>-d<SP>4</SP> for destroying the foam, besides a cooler e<SP>1</SP>-e<SP>4</SP> for each of them, and an aerator g corresponding to the size of each of said coolers. The partitionsshown in dotted lines-which separate the compartments need not exist at all, being of a purely ideal nature; or alternatively; they may be of reticulated or adequately perforated form but, in this case, should not extend to the top or bottom of the compartment lest the passage of mash from one compartment to the next be impeded. The filling heights FH, the rising heights SH due to aerating, and the admitted foam thicknesses SH' should be the same in all the compartments, said compartments contain sieves f (Fig. 2, not shown), whose heights above the mash level are adjustable. The regulating- valves RV serve to regulate the quantities supplied of the nutritious solutions NL<SP>1</SP>-NL<SP>3</SP>, and the quantities of air supplied to the individual compartments through the pipings L for sterile air. The total circulation I is regulated by a pump b<SP>5</SP>, which draws the mash through the vat across the flow of rising air bubbles and delivers it through a pipe back to distributer d', whilst additional regulation of the volume of mash can be achieved by changing the filling height FH in the vat by means of a height-adjusting device for the outlet of the taking off pipe b. In order that the supply of nutritive solution and the degree of aerating may keep constant, it will be necessary that the yeast content of the mash in the vat should keep unchanged and that the contents of the compartments should be increased with respect to each other according to the ratio that can be gathered from the diagram of Fig. 3 (not shown), the filling heights being the same.

Title: Method of and apparatus for separating fine material
IPC: B07B4/02
Filed: 1921-08-15
Abstract: 187,381. Roth, G. Aug. 15, 1921. Pneumatic separating.-Pneumatic separating apparatus consists of a number of concentric receivers extending one within another, with spreading plates and a centrifugal blower at the lower end of the receiver supplying air for separating purposes, the separation being effected in several separate currents of which the main current is blown through the material while a weaker current is blown through, or induced currents are drawn through the coarse material already treated by the main current. As shown in Fig. 1, the apparatus consists of a number of concentric chambers formed by casings a, b, x, c, d, the inner one a being formed as a cone shaped hopper a<1> at the top having a flange a <2> extending downwardly into the outer chamber. A tube a<3>, to the bottom of which is attached a blower e, is provided with side plates i and a spreader plate f and is fixed to the shaft g by means of which it is rotated. The material is fed by the tube k on to the plates i which distribute it over the surface of the spreader plate f, the plate f spreading the material out as a horizontal layer in the space A between the casings c, x. Air is drawn down the tube a<3> to the blower e, the main current of air issuing at e<2> through a sieve, and passing through the material, a weaker current issuing at e<1> and carrying to the main current any fine material not already separated out. The coarse material drops out at the opening m while the fine material is carried past plates n which separate out any coarse particles mixed with the fine material. The fine material drops between the casings c, d, and is collected at o, the air passing down the hopper a<1> to the blower e. Parts q are turned up on the sides of the hopper a<1> to deflect any fine material carried over into the hopper through openings w into the space between the casings b, x from which it is removed by means of a sloping bottom j and doors y, z<1>, z<2>. In the arrangement shown in Fig. 2, the space A is closed at the bottom by a plate r and dished portion s with a space v between. Blades t are formed on the underside of the blower e and produce an auxiliary current of air. Induced currents pass from a chamber B to the space A through the spaces between the blower e and casings s, v and assist the separating action in a similar manner to that described for the weaker current in the arrangement shown in Fig. 1.

Title: Improvements in or relating to force balance systems, especially appertaining to differential pressure transducers
IPC: G05D16/20
Filed: 1961-06-16
Abstract: 995,847. Photo-electric control of pressure. GPE CONTROLS Inc. June 16, 1961 [June 17, 1960], No. 21860/61. Heading G1A. [Also in Division G3] In a system for controlling the pressure within a furnace wherein a pivoted flag attached to the diaphragm of a pressure transducer which communicates with the furnace, is caused to interrupt and vary the light falling on a photo-cell and wherein the signal from the photo-cell is used to regulate the said pressure, a force balance system is provided to counteract elastic restraining forces on the movement of the flag, comprising a magnetic member disposed in a magnetic field such that magnetic forces transmitted to the flag are in opposition to the elastic restraint thereon. The pressure transducer 12 comprises chambers communicating with the furnace and outside atmosphere separated by a flexible diaphragm 20. The flag 22 is connected to one end of a beam 18 which is pivoted by a diaphragm pivot 19 and connected at its other end to the diaphragm 20. Movement of the flag, caused by movement of the diaphragm 20, between a light source 24 and a photo-cell 26, causes the output of the photo-cell to vary and amplifier 16 to feed a corresponding signal to a coil 68 movably situated in the field of a permanent magnet 70. The coil 68 is thus caused to move and direct an oil delivery pipe 56 onto tube 60 on tube 58. These two tubes communicate with oil filled spaces respectively above and below a piston 64 connected to control a valve 50 varying the pressure within the furnace. The output of amplifier 16 also controls the position of a nut 36 by energizing a coil 32 which is movable within the field of a permanent or electromagnet 42 and fixed to an L- shaped arm, pivoted at 30 and carrying nut 36 on a threaded arm 38. The action of the nut is to stop further rotation of the beam. The force balance system is concerned with overcoming the restraining forces produced at pivots 19 and 30, and comprises a block of magnetic material 72 fixed on the end of arm 34 and normally positioned in a neutral position between two adjustable permanent magnets 74 and 76. Movement of coil 32 moves the block 72 into the attracting field of one of the magnets, whereby a force is produced in such a direction to counteract the said restraining forces. The magnets 74 and 76 may be variable strength electromagnets. In another embodiment, Fig. 3, the pressure transducer may be a Bourdon tube 84, subject to internal pressure and fixed at one end. At the other end is fixed a core of magnetic material 86 positioned in the field of magnets 88 and 90, and a rod 98 connected to beam 92 (beam 18 of Fig. 1). A change in curvature of the Bourdon tube under a pressure change pivots the beam about pivot 94 and moves core 86 towards one of the magnets to produce a counteracting force.
