Title: Improved manufacture of alcohol and yeast
IPC: C12P7/06
Filed: 1923-06-26
Abstract: 205,813. Klein, E. Aug. 29, 1922, [Convention date]. Yeast; materials for making alcohol.-In preparing alcohol by fermentation and utilizing the residual liquor after separation of the alcohol for the formation of yeast by the aeration process, phosphorus compounds such as phosphates are added to the materials used in forming the mash prior to or during the fermentation period. Nitrogen-containing materials and other yeastnourishing substances may be added after the first fermentation. A mash prepared with a mixture of rye, malt and superphosphate is acidified. Fermentation is effected in a concentrated liquor to diminish yeast formation. Alcohol is separated by distillation. The residual liquor is clarified and fermented with yeast while being vigorously aerated. In using mash prepared' from rice or other materials poor in nitrogen, the fermentation to produce alcohol is stopped before completion, and nitrogenous substances such as uric acid, calcium cynanamide, extracts of acrospines or cotton seed cake, are added prior to the fermentation to produce yeast. In using worts from molasses or crude sugar, additions of phosphates are made and the alcoholic fermentation is not carried to completion. The wash, after distillation to separate alcohol, is treated to yield the maximum quantity of yeast, additions of wort from molasses, superphosphates and ammonium sulphate being made periodically. The yeast is afterwards improved' by growth in a mash prepared from grain and superphosphate. Specification 203,300 is referred to.

Patent GB-227902-A (GB)
Title: Improvements in grinding machines
IPC: B24B19/00
Filed: 1923-10-20
Abstract: 227,902. Kessel, H. Oct. 20, 1923. Hollow-grinding razor and like blades; cutting-edges shaping and treating; wheels. - In a grinding- machine, more particularly for grinding knife blades, of the kind in which the work-piece is carried in a holder slidable between a pair of grinding-wheels set at an angle to one another and adjustable horizontally, the wheels 16 have rounded grinding-faces and are carried in bearing members 15 mounted on horizontal axes or pivots 14 so as to be rocked both towards or away from the work; work-pieces can thus be ground with straight or convex or straight and convex sides. The pivots 14 are carried by intermediate plates 9 pivoted at 8 to main plates 3 which are pivoted at 2 to the machine bed and carry adjustable screws 5 contacting with a verticallyadjustable cone 7 by which the horizontal adjustment of the wheels is obtained. The bearing members 15 are balanced by tension springs 17 and rest on the ends of vertical rods 18 supported by horizontal levers 19 resting at their free ends on arms 20 carried by an horizontal shaft 21. The length or leverage of the arms 20 can be varied and a lever 24, which has a forked end pivotally engaging a projection in the shaft 21, can be moved by a handle 25 to place its free end in contact with any one of a series of cams 23 in the driving shaft 22, to vary the extent of the flat surface to be produced. To produce a convex surface, or a flat and a convex surface, the wheels are rocked about the pivots 2 in synchronism with the rocking about the pivot 14 by moving a lever 6 connected to the cone 7. To produce a longitudinal taper in the blade, the wheels are also rocked by moving the intermediate plates 9 on their pivots 8 by means of a treadle 11 connected by cords 12 to the plates; the grinding-faces of the wheels are curved about the pivots 8 as centres. A work-holder for a pair of blades, one side of each of which can be ground simultaneously, comprises a pair of blades 33 connected by springs 34 with bolts 35 carrying a pivoted traversing lever 32. The holder, with the work-pieces held against the outsides of the blades 33 in any suitable manner, is guided on a rail 31 and the blades 33 are forced apart by a tongue 36 to press the work-pieces against the grinding-wheels; a lateral grinding- arrangement comprising adjustable rods 38 carried by the blade 33 and contacting with adjustable inclined guide-rails 40, may be used to twist the blades 33 and give the longitudinal taper to the work-pieces, the blades being held in their movement by guide rollers 37, a flange 44 on the tongue 36 and the bolts 35. The blades 33 may be slightly recessed at the place where the manufacturer's mark is stamped on the workpiece so that the pieces can give, a little to preserve the mark.
Patent GB-947927-A (GB)
Title: Heater control circuit
IPC: G05D23/24
Filed: 1960-07-28
Abstract: 947,927. Automatic temperature control. MONSANTO CHEMICAL CO. July 28,1960 [Aug. 14, 1959(3)], No. 26233/60. Heading G3R. In Fig. 1, the control circuit described in Specification 907,082 is modified by providing additional relay contacts 43 which permit the voltage applied to the bridge 11 to be controlled. When the relay operates and the relay contacts 42, 43 are closed, a resistor 44 in series with the supply to the bridge is shunted and a higher voltage is applied to the bridge. Increased selfheating of the thermistor 12 follows, resulting in more rapid decrease in the resistance of the thermistor. The heating cycle is thus shortened and heating more uniform. In a further embodiment, Fig. 2, a transformer 60 energizes the heater, and a feedback transformer 66 reflects the voltage across the heater, when it is on, into the input circuit of the bridge. A neon tube 70 prevents flow of current through the primary winding 68 of the transformer 66 when the heater is not in operation and indicates when the heater is on. The increased voltage applied to the bridge when the heater is on shortens the heating cycle as before. When the heater is not on, the secondary winding 67 of the transformer 66 acts as an impedance in the input circuit of the bridge and the voltage applied to the bridge is substantially lowered. The self-heating of the thermistor is thus reduced, the off period of the heater is shorter than normal, and the cycling rate of the heater is further increased. Specification 947,928 also is referred to.

Patent GB-1509099-A (GB)
Title: Process for the zonewise electropolishing of the inner surfaces of containers
IPC: C25F3/16
Filed: 1976-06-24
Abstract: Electroconductive metallic inner surfaces of large-volume containers are electropolished zone-wise. In the process, a flow of current is generated and maintained in a bath fluid serving as the electrolyte. The metallic surface connected to the anode of a DC source is covered entirely or in part by the bath fluid. A metal electrode connected to the cathode of the DC source is completely immersed in the bath fluid, the metal electrode being positioned at a small distance from the inner surface of the container, and the container and the metal electrode being in a state of slow relative movement. In this arrangement, the metal electrode is fixed and the surface of the container revolves slowly about the longitudinal axis of the metal electrode, or the surface of the container is fixed and the metal electrode sweeps the surface of the container. That part of the cathodic metal electrode which during the electropolishing process faces away from the surface portion to be polished is screened with the aid of an electrically non-conductive material, so that the current lines between the cathodic metal electrode and the anodic surface are concentrated and cover the shortest distance from the cathode to the anode.
