Title: Improvements in or relating to the manufacture of barium compounds
IPC: C01B33/24
Filed: 1928-03-03
Abstract: 312,975. Wittouck, S. March 3, 1928. Barium silicates.-In the production of barium silicates, for instance di- or tri-barium silicate by calcination of say silica or mono-barium silicate with say barium sulphate for instance at 1500‹ C. and in the presence or absence of carbon or gases such as carbon monoxide, fusion is avoided by addition of a diluent infusible at the calcination temperature. Preferably the diluent consists of a quantity of the silicate which it is desired to obtain, and preferably so much is used that fusion of the whole mass undergoing calcination is avoided. A portion of the product from one operation may be used as diluent in a succeeding operation whereby the process may be made continuous; in such case there is preferably removed from the process at each operation as much of the product as corresponds to the reacting components. Sulphur, sulphuric acid, or carbon dioxide evolved in the process may be recovered.

IPC: H02P7/34
Filed: 1925-03-14
Abstract: 242,145. Zßvada, B. March 14, 1925. Dynamos and motors combined for transmitting power; equalizing load on generator. - In a power transmission system comprising a direct current. generator G<1> supplying energy to a reversible motor j<1> and means for regulating the voltage of the generator throughcut a range of positive and negative values, a prime mover A' is coupled to an asynchronous alternating current machine C<1> electrically connected to the power supply and coupled to the generator G<1> and so regulated that when the generator is under no load or low loads the asynchronous machine C<1> acts automatically to feed the line r<1>, s<1>, t<1> but otherwise acts as a motor fed by the line to assist the prime mover A<1> in driving the generator G<1>. A fly-wheel B<1> for taking up part of suddenly increased loads may be enclosed in a fluid-tight casing that is exhausted or filled with rarified gas or steam. The prime mover A<1> may be a reciprocating engine or a turbine, and the fly-wheel may be omitted. An adjustable resistance, c<1> for regulating the slip of the asynchronous machine C<1> may also be used to compensate lag of phase. The operations of switching, interrupting or stopping to regulate the slip may be controlled by a relay or motor responsive to the current and voltage of the machine C<1>. A single exciter D<1> may be used for several machines. The generator G<1> may be disconnected from its driving shaft when C<1> is acting on a generator to supply energy to the bus bars R', S', T'. The stuffing-boxes for the shaft of the fly-wheel contain a fluid packing. In the form shown in Fig. 3, smooth or ribbed discs w on the fly-wheel shaft rotate in compartments partly filled with fluid, which they set in motion so as to form fluid rings or seals capable of sustaining a difference of pressure. In another form the stuffing-boxes are formed as centrifugal pumps with one or more stages, which maintain a circulation of fluid from the inside of the fly-wheel casing to the outside. The fluid may be mercury or oil. The latter may be circulated for lubricating purposes.

Title: Improvements in and relating to index signal generating means and systems
IPC: H04N9/24
Filed: 1959-05-22
Abstract: 926,184. Frequency dividing circuits. D. E. SUNSTEIN. May 22, 1959, No. 7141/62. Divided out of 926,182. Class 40 (6). A signal of frequency 2.5 ft appearing on line 91 is divided by 2.5 to obtain a signal of frequency ft on line 100 by means of a circuit 86 comprising a mixer 92 in which the signal of frequency 2.5 ft is combined with a signal of frequency 2.0 ft obtained by multiplying the mixer difference frequency signal 0.5 ft by four in two frequency doublers 84 and 102, the arrangement being characterized by the provision of a separate phase reference signal of frequency 0.5 ft which is applied to mixer 84 to initiate the operation of circuit 86 in the correct phase. The arrangement forms part of a colour television receiver in which the signal of frequency 2.5 ft and the phase reference signal of frequency 0.5 ft are beam-position index signals derived during the scanning of a cathode-ray tube 12. The signals are derived either in a photo-electric cell (as illustrated at 78) or from an electrode of the tube, the signal of frequency 0.5 ft appearing only briefly at the commencement of each line scan before the signal of frequency 2.5 ft which persists throughout the remainder of the line. The signals are separated by tuned amplifiers 82 and 88, the input connection to amplifier 82 including a gate 80 which is opened at the beginning of each line scan to allow passage of the signal of frequency 0.5 ft by a line synchronizing pulse applied to trigger a gate-controlling flip-flop 96 at line 98 and which is closed upon the subsequent appearance of the signal of frequency 2.5 ft by a signal which is derived from the output of amplifier 88 by means of a detector 94 and applied to reset the flip-flop. The frequency ft comprises the cathode-ray tube screen colour triplet (red, green and blue) repetition frequency. In general the main indexing frequency (2.5 ft in the example described above) may be any non-integral multiple greater than 1 times the frequency ft, 2.5 ft being the preferred frequency, but frequencies of 1.5 ft, 3.5 ft, 4.5 ft and 5.5 ft also being referred to. Specification 926,183 also is referred to.

Title: Improvements relating to monobed ion-exchange methods and apparatus
IPC: B01J49/00
Filed: 1959-03-02
Abstract: 882,254. Ion-exchange. ZWICKY, J. F. Feb. 22, 1960 [March 2, 1959 ; March 24, 1959], Nos. 7192/59 and 10184/59. Class 46. A monobed resin mixture 1 is disposed between top and bottom porous diaphragms 16 and 3 respectively, the vessel 2, being provided with single ports 5 and 6 at the top and bottom and with an intermediate annular port 17 communicating with the interior of the vessel through an annular porous diaphragm 18. For separation, the port 5 is connected to vacuum and the port 6 to the supply of water, while the intermediate port 17 is cut off by keeping the valve 20 closed. Separation is effected with the plane of separation between the lower, cation, resin and the anion resin approximately at 21. For regenerating the anion resin, the port 5 is connected to a supply of caustic-soda solution and the port 6 to a source of vacuum, while the intermediate port 17 remains cut off. For regenerating the cation resin, the valve 9 is closed, the port 6 remains connected to vacuum and the intermediate port 17 is connected to a supply of acid. There is a flow of acid through the lower, cation, part of the separated bed only. For a washing stage, if required, the port 5 may be connected to vacuum and the port 6 to the supply of deionised water, while the intermediate port 17 is cut off, so that there is an upward washing flow. However, the bed can be dried effectively by the vacuum at the end of the cycle and in this case no washing will be required at the end of the regeneration steps. As an alternative for the above-described regeneration under vacuum, regeneration under gravity may be employed. In this case, a final washing stage should be used. Remixing is effected, with the column wet, by applying suction, by the vacuum pump, to the port 5 at the top of the column, while the port 6 at the lower end of the column is connected to atmosphere. Large bubbles of air are entrained through the water-resin mixture and cause remixture of the resins. For normal running of the column, the port 5 is connected to the supply of raw water and the port 6 to the vessel or system receiving the treated water, the intermediate port 17 remaining cut off. The water is thereby de-ionised in downward flow through the column 1. After regeneration, it may be convenient to use the vacuum pump to draw off the first of the treated water, that is until the said water is fit for delivery to the said vessel or system. Normal running may be under gravity or under pressure applied to the column 1 from above. A modification of the above method is also described in which there is no intermediate port for regeneration.
