Title: Improvements relating to anti-foam systems for fermentation processes
Inventor: RICHARDS ANTHONY EDWARD
IPC: C12M1/36
Filed: 1968-06-20
Abstract: 1,236,817. Automatic fluid level control system. DISTILLERS CO. (YEAST) Ltd. June 11, 1969 [June 20, 1968], No. 29514/ 68. Heading G3R. Rise of foam to a predetermined level in a fermentation vessel causes operation of a pump to add a predetermined quantity of foam suppressing agent. As described, when foam in a fermentation vessel rises into contact with an electrode at a predetermined level, a circuit is completed between the electrode and the vessel to operate a transistorized relay. If this operation persists for a period determined by a short time delay relay, a reciprocating pump is operated pneumatically to dispense a single dose of anti-foam agent into the vessel. The amount dispensed is determined by adjustment of the stroke of the pump. The pump is operated at intervals until the foam level falls and an alarm is operated if this does not occur within a period determined by a long time delay relay. Further operation of the pump is prevented when a counter registers a number of operations equal to the number to which it is set. Pilot lamps indicate various conditions of operation and a switch is provided for manual control of the pump.

Abstract: 714,940. Glass compositions. LOEFFLER, J. Dec. 24, 1951 [Dec. 22, 1950], No. 30086/51. Class 56 Glass consists wholly or predominantly of rare earth metal oxide-alumina-silicates, and has 10-70 per cent. rare earth oxides, and 10-20 per cent. aluminium oxide. The glasses can be melted at conventional or even lower temperatures and have a low viscosity when molten. The oxides of various rare earth metals may be used in order to vary the properties of the glass. It is advantageous to use rare earth metal oxide-alumina-silicate mixed with minor amounts of divalent oxides or aluminium silicates of the latter, and small amounts of alkalis and/or phosphoric acid and/ or B 2 O 3 , clarifying agents, opacifying agents &c. may be added. Examples giving the weight percentage composition are, (1) La 2 O 3  30, BeO 5.5, K 2 O 0.5, Al 2 O 3  18.0, SiO 2  46.0, which melts at 1350‹C., has a lower thermal expansion than hard porcelain, shows little tendency to devitrify, is stable in water and resistant to acids and alkalies, (2) as in (1) with the K 2 O omitted, (3) La 2 O 3  50, ThO 2  10, BeO 3.1, Al 2 O 3  11.8, SiO  2  24.9 has a refractive index of 1.75 and abbÚ value slightly higher than 50, (4) The rare earth oxide may be used to colour the glass for use for optical purposes and jewellery, and a, bright brilliant green glass contains, PrO  2 O 3  54, PbO 10, Al 2 O 3   11, K 2 O 0.5, SiO 2  24.5. Glasses containing very high amounts of rare earth metal oxides attack the clay melting vessels at high temperatures and must therefore be melted carefully.

Title: Process of separating aqueous and other vapors from liquids and solids and for preparing dilute sulphuric acid
IPC: C01B17/74
Filed: 1919-12-03
Abstract: 159,054. Maass, O. Dec. 3, 1919. Evaporating and concentrating plant and processes.-Aqueous or other vapours are absorbed from material by the rarefaction of the enclosing atmosphere by or in presence of an oscillating body of absorbent liquid; by subjecting sulphuric acid to vacuum in presence of water as the absorbent, pure dilute sulphuric acid is obtained. As shown, the material to be dried is contained in a vessel 11 heated by a water bath and connected with an elongated reservoir 15, the bottom of which is connected through a V-tube with a reservoir 17 and through a branch 20 and a V-tube with a reservoir 23. The reservoir 15 contains a means 24 provided with a large surface capable of being wetted by a desiccating-agent with which the reservoir 15 is filled initially to the level b. Suction is applied to the tubes connected with the reservoirs 17, 23 whereupon the liquid level falls in the reservoir 15 below its junction with the branch 20; on admitting atmospheric pressure to the reservoir 17 the liquid rises again, trapping air in the branch 20 and forcing it out through the reservoir 23. Alternate subjection of the reservoir 17 to vacuum and to atmospheric pressure ultimately removes air and by the oscillation of the liquid continuously renews the desiccating liquid on the means 24.

Title: Improvements in or relating to generator charging systems for electric batteries particularly for use with radio apparatus
IPC: H02J7/34
Filed: 1925-12-02
Abstract: 265,328. Igranic Electric Co., Ltd., and Wright, S. R. Dec. 2, 1925. Charging and discharging batteries.- A battery charging system comprises a motor generator, a charging control coil for simultaneously closing a charging circuit and a power circuit for the motor and a battery protection coil adapted to open these circuits when the battery discharges into the generator. This arrangement operates intermittently during the starting up of the generator set. An ampere-hour meter deenergizes the charging control coil when the battery is fully charged. A discharge control coil under manual control is adapted to open the circuit of the charging control coil and to close a discharging circuit. Fig. 1 shows a system with two motor generators G<1>, G<2> for charging a low-tension battery L.T. and a high-tension battery H.T. for radio apparatus, supply to which is normally completed by a switch d' closed by the energization of a discharge control coil d. To charge the batteries the push button switch B is opened, the coil d, thus de-energized, opening switch d<1> and closing d<2>, d<3> and d'. The charging control coil c is thus energized should the ampere-hour-meter switch a be closed and switches c<1>, c<2>, c<4> are closed to complete the charging circuits simultaneously with the closing of switch c<3>. The last completes the supply circuit connection to the armatures of motors M<1>, M<2> and the fields of both motors and generators. The battery-protection coil p is however traversed by a current from the battery H.T. and overpowers the coil c throwing open the switches c<1> - - c' which close again directly the coil p is de-energized by the switches c<2>, c<4>. This operation is repeated until the motor generators have gained sufficient speed to reduce the coil p to ineffectiveness. The two batteries are designed to charge in the same period and charging is stopped by the ampere-hour meter A opening the switch a. The batteries may be discharged and charging stopped at any time by closing the switch B, while, with a pilot lamp l, may be at a distance; but neither charge nor discharge can take place if the main switch S, be open. In a modification a switch d<1> is placed in the negative lead of each battery, the switch d<3> is dispensed with and ammeters are placed in each charging circuit.
