Title: Manufacture of glycerol from sugar
IPC: C12P7/20
Filed: 1920-01-20
Abstract: Glycerine is obtained by fermenting sugar in alkaline solution in presence or not of a catalyst.  Suitable alkaline substances are ammonium phosphate, ammonium carbonate, sodium phosphate, carbonate, or bicarbonate, an amine, a salt of an amine, or mixtures of these; suitable sugars are grape sugar, invert sugar, saccharified starch, maltose, and purified molasses or syrup. Commercial yeast, yeast cultures, or other species of yeast may be used for fermenting, and food for the yeast may be added to the liquid; manganese sulphate and iron sulphate are suitable catalysts.  In an example, 200 grm. of sugar and 140 grm. of disodium hydrogen phosphate are dissolved in 2 litres of water and fermented by 50 grm. of commercial yeast at 30 DEG  C.; the liquid is afterwards decolorized by boiling with animal charcoal, filtered, evaporated, and the glycerine distilled off or extracted by alcohol.  The yield is 12 per cent of the sugar.  The fermented liquid may be purified by lime, magnesia, or iron compounds, before concentration.

Title: Improvements in or relating to pressure gauges of the ring or hydrostatic balance type
IPC: G01L7/24
Filed: 1937-01-22
Abstract: 489,284. Pressure gauges. ELECTROFLO METERS CO., Ltd., and FRENCH, J.W.E. Jan. 22, 1937, No. 1941. [Class 106 (ii)] An instrument of the ring or hydrostatic balance type has coupled to the displaceable member a casing containing a plurality of contact rods of different lengths arranged to dip into mercury or other electrically conducting liquid, such rods being in circuit with an electrical instrument. The annular casing a contains liquid b and is provided with a partition c dividing the casing into separate chambers d, e to which pressure fluid is conducted by flexible pipes f. The casing is mounted on a knife-edge g. The variable resistance device h is directly suspended from the casing by a rod i and comprises resistance sections connected to rods of different lengths adapted to dip into conducting liquid k in a reservoir l. As more and more rods dip into the mercury the resistances are short-circuited with the result that as the upthrust of the liquid balances the movement of the casing the effective resistance of the circuit varies and by suitable arranging the conductors a satisfactory indicating scale is obtained on an electrical instrument in the circuit. Preferably however a liquid displacer m, is also adapted to dip into the mercury so formed that the indication is given according to a desired law. Balance weights may additionally be used for this purpose.

Abstract: 297,628. Tritsch, D. T. Aug. 23, 1927. Divided on 285,967. Fixed-chamber apparatus.-The delivery valve is interlocked with the supply pipe adjusting means so that either can be operated only when the other is in correct position. The supply pipe 2 fitted with the usual antisplash disc 9 float 8 and check valve as in Specification 285,967, is raised and lowered by rack and pinion operated by a hand wheel 17 and spindle 16. At intervals along the rack 14 corresponding with the different volumes to be delivered are notches 14<x> adapted to be engaged by the end of a lever 46 pivoted at 47. When the rack is correctly positioned this lever may be fully rocked by means of the handle 48 so as to remove a roller 55 from teeth 56 on the valve spindle which otherwise is locked against opening. On the other hand if the spindle is turned to deliver the measured liquid a cam 58 on the spindle displaces an arm 59 connected through spindle 50 and arm 49 with the lever pivot 47 to prevent release of the lever from the notch in the rack so that adjustment of the pipe 2 cannot take place while the tap is open. With counting-apparatus.-The rack-operating spindle 16 has a worm 35 engaged by the end of an arm 34 pivoted at 67. Adjustment of the pipe 2 therefore rocks this spindle and an arm 65 so as to shift a stepped barrel 64 along the tap spindle to vary its effect upon the pinion 70 geared with the counter 60 through shafts 73, 68.

Abstract: 697,859. Cooling systems for engines; heating vehicles. DAIMLER-BENZ AKT.-GES. Feb. 2, 1951 [Feb. 4, 1950], No. 2667/51. Classes 64 (ii) and 64 (iii) Relates to cooling systems for liquid-cooled engines in which cooling liquid circulating under pressure in the engine cooling-jacket is heated nearly to boiling point and vapour formed from said liquid upon cooling or pressure reduction is separated from such liquid and is returned to the cooling circuit. According to the invention the vapour is separated by a vapour-separator which directly adjoins the circulating pump or by the pump itself being adapted for effecting such separation. In the form shown, liquid coolant discharges from the cooling jacket of engine a, through pipe b to centrifugal pump c and is returned to the engine through pipe d. Vapour separated from the coolant by the pump or by a separator directly adjoining the pump is discharged through a pipe f to a heat exchanger g (e.g., a vehicle heating radiator), and thence through a pipe h, through the upper part of a storage vessel i to a condenser k, from which condensate is passed to the storage tank i for return to the engine by pump by way of a pipe m leading either directly to the centrifugal pump c (as shown) or to the pipe b leading to the pump c. A valve q enables the vapour to be directed through a by-pass p thus cutting out the heat exchanger g from the system.
