Title: Voltage regulating system
IPC: H04M19/00
Filed: 1944-08-01
Abstract: 587,179. Automatic voltage regulators. STANDARD TELEPHONES & CABLES, Ltd. Aug. 1, 1944, No. 14675. Convention date, Aug. 31, 1943. [Class 38 (iv)] In a rectified output voltage regulator, a selenium plate rectifier RB is connected to the secondary 9 of a constant voltage input transformer CUT through an auto-transformer AT in series with the A.C. winding 14 of a saturable core transformer SC. The rectifier supply voltage is regulated in response to load conditions by coils 25, 26, 27, 28 on the transformer SC energized by the D.C. output of the rectifier so as to vary the reactance of winding 14. The coils 27, 28 are arranged in shunt relation to the load to provide additional regulation to compensate for the non-correspondence of the magnetizing and voltdrop curves of the regulating means and are brought into operation by a relay circuit when the regulation of the series coils 25, 26 becomes inadequate. The said relay circuit comprises a marginal voltage relay 37 connected across the load and having high and low voltage contacts H, L. For a falling voltage, a relay 35 is first operated through conductor 32 and relay 33 to connect coils 27, 28 in circuit through a resistor 36. For a further decrease in voltage, resistor 36 is short-circuited by a relay, 42 and on the voltage decreasing still further, an alarm circuit 48 is energized by a relay 40. For an increasing voltage the reverse occurs through conductor 45 until all the regulation is left to coils 25, 26, after which a further increase in voltage causes an alarm circuit to be energized by a relay 38. A battery B may be charged on the output leads, a higher E.M.F. for this purpose being obtained by operating a push-button 50 which, through the medium of a multiple switch contactor 34, changes a tap on the auto-transformer from c to d at the same time closing a circuit 52 for a lamp charge indicator and short-circuiting windings 14, 25, 26, 27, 28 to remove the automatic regulation control. The auto-transformer is also provided with taps a and b which are used in accordance with the ageing of the rectifier plates and eliminated when the plates are fully aged.

Filed: 1924-02-04
Abstract: 238,166. Mewes, R. F., and Mewes, R. K. E. Feb. 4, 1924. Separating gaseous mixtures by liquefaction. -In the liquefaction and separation of gaseous mixtures, such as air, the low boiling-point substance (nitrogen) issuing at the upper end of a rectification column is passed through a condenser in stages and the condensate is collected at a number of points from one or more of which it is returned to the column, the gaseous or liquid nitrogen being withdrawn for use from the last stage. Nitrogen condensing in the tubes 57, Fig. 1, falls back into the column and nitrogen condensing in the tubes 58, 59 collects in the compartment 60 whence it overflows through pipes 61 into the column. Gaseous nitrogen is withdrawn at 4. Liquid oxygen from the vaporizer 8 passes through a reducing valve 36 and is used as condensing medium, gaseous oxygen being withdrawn at 5. Cooled, compressed air initially withdrawn from the column at 62 is passed through coil 55, a coil in the compartment 60 and reducing valve 64 to the middle of the column. In a modification liquid nitrogen withdrawn from one stage is used as condensing medium for an oxygen condenser surrounding the rectifying column. An oxygen vaporizer as shown in Fig. 3 may be used in combination with the nitrogen condenser. It is divided into compartments by circular baffles and a hood 162, liquid oxygen being withdrawn from the centre by the pipe 166 for use in the nitrogen condenser. The vaporizer is heated by compressed air passing through the coils 157, 163 whence it is expanded and led to the middle of the column and by compressed gaseous nitrogen in the coil 159, the nitrogen being expanded and led to the upper part of the column.

Filed: 1966-04-04
Abstract: 1,116,315. Detecting gases. NATIONAL RESEARCH DEVELOPMENT CORPORATION. April 7, 1967 [April 4, 1966], No. 14821/66. Heading G1B. Apparatus for the detection of gases comprises a gas detecting element 28 in a chamber 1 into which chamber, in one mode of operation gas can pass from the surrounding atmosphere through a diffuser 22 and nozzle means 11 are provided for permitting a second mode of operation in which a layer of gas, other than from the surrounding atmosphere is projected across the outer face of the diffuser so that only gas from the layer can pass through the diffuser and into the chamber. The detecting element 28 is connected to leads 26 mounted in an insulator 24 and comprises an electrically heatable catalytically acting element which varies its resistance with changes of temperature. A non-catalytic compensating element 29 is mounted in a second chamber 2. Below each diffuser 22 which is made of charcoal, a second diffuser 23 is mounted so that in the first mode of operation gas from the atmosphere passes through each diffuser 23 and forms a layer in the gap between the diffusers, from which layer gas passes through each diffuser 22 into the chambers 1 and 2. In the second mode of operation, gas. from a rubber bag is injected into the nozzle 11 through a duct 9 and into annular channels 8. Sintered bronze rings 16 are sealed in each channel by O-rings 17, 18 and provide a resistance to the flow of injected gas so that the pressure in the lower part of each recess 8 rises sufficiently to produce an evenly distributed radial flow of the gas to be sampled. In a modification, both elements 28, 29 are mounted on either side of a partition in a single chamber.

Title: Liquid crystal display device/driving circuit arrangemt
IPC: G09G3/18
Filed: 1976-04-13
Abstract: 1523543 Alphanumeric displays and circuits therefor SUWA SEIKOSHA KK 13 April 1976 [23 April 1975] 15045/76 Heading G5C In a liquid crystal display device 7 with first and second sets of electrodes separated by the liquid crystal medium, each set being divided into connected groups, serial data is loaded into a shift register to be read and stored in parallel memory circuits feeding the respective groups of the first electrode set while potentials are applied to the groups of the second set to allow multiplex working. With eight segments per digit including decimal point, electrodes of matching segments in pairs of adjacent digits 8-9, 10-11, 12-13 form the groups of the first set while counter electrodes of alternate digits 8-10-12 and 9-11-13 form the groups of the second set. BCD output 1, e.g. from a calculator or clock, stored in serial groups of 4 bits in register 2 is coded into seven segment form in decoder 3 with the decimal point bit added at 5, to make available serially as a word having a bit for every segment in the display, repeated at regular intervals, to shift register 16-17-18, in which the three sections each receive the 8 bits of data either for digits 8-10-12 or for digits 9-11-13 according to the setting of selector 25. Each time the register is loaded, memory circuits 19, 20, 21 retain in parallel the information and via booster circuits 22, 23, 24 apply 2 Vo, i.e. a potential above the liquid crystal threshold (Fig. 2, not shown), to the segments of the digit pairs corresponding to 1-bits m/te data. At the same time zero voltage is applied to counter electrode groups so that a voltage 2Vo appears across selected segments of the addressed digits. After two data words have been handled, for the following two periods a voltage applied to input B causes inversion of the data fed to registers 16-17-18, and the voltages to the counter electrode groups are changed to 2Vo so that - 2Vo appears across the selected segments, thus providing an A.C. drive (Fig. 3, not shown) as the cycle continues. In an alternative embodiment, two groups of four segments individual to each digit oppose counter electrodes connected in four groups of two segments commoned over all digits (Fig. 4, not shown). The circuits in both embodiments may be integrated.
