Title: Improvements in or relating to electronic voltage regulators
IPC: G05F1/52
Filed: 1943-06-10
Abstract: 566,895. Automatic voltage regulators. HADFIELD, B. M. June 10, 1943, No. 9313. [Classes 38 (ii) and 38 (iv)] A circuit for maintaining the voltage across a load R constant, irrespective of fluctuations in supply voltage B and changes in load current i2, and which may be used also for smoothing rectified alternating current, comprises a control valve V1 of the pentode type, the anode voltage of which is influenced by the supply voltage and load current changes and affects the grid potential of a valve V2 forming a variable impedance in series with the load and having its grid connected to the anode of the control valve. The grid circuit of the control valve includes an adjustable constant source of potential pE derived from a potentiometer Rp shunting a neon tube N connected across the supply B in series with resistances α, #, so that by adjustment of the potentiometer the load voltage may be controlled. The resistance B and a resistance γ provide, respectively, components of control grid voltage for the valve V1 which are proportional to the supply voltage and load current. Fluctuations in the values of these components are amplified by the control valve and applied with phase reversal, to the grid of V2 by the anode resistance P. Negative feed-back for V1 is provided by a cathode resistance Q to stabilize the control stage, whilst a resistance S, connected as shown and of a value equal to the product of Q with the control grid/screen grid amplification factor of V1, is provided to increase the range of output voltages of this valve by cancelling the effect of standing anode current. To improve frequency response, a condenser K may shunt resistance Q, thus making the time constants of the anode and cathode circuits of VI of the same order. The triode valve V2 may be replaced by a pentode or tetrode having its screen connected to the positive supply rail, when an independent and additional current for a constant-current load may be taken from between the anode and positive supply rail.

Patent GB-469599-A (GB)
Title: Improvements in or relating to means for producing multiple flash signals
IPC: G08B5/40
Filed: 1937-04-02
Abstract: 469,599. Visible signalling-apparatus. SVENSKA AKTIEBOLAGET GASACCUMULATOR. April 2, 1937, No. 9401. Convention date, April 3, 1936. [Class 118 (ii)] In a system in which gas is used to produce groups of flashes at timed intervals by connecting two gas-controlled flashers in series, the pressure in the pipe joining the flashers before the first flasher discharges is used to control the discharge. Gas from supply 5 is fed to chamber 3 of the primary flasher 1. When the pressure on diaphragm 2 overcomes the pressure of spring 10, valve 8 opens and gas is fed to the secondary flasher 11 which is adjusted to operate at a faster rate than flasher 1. Consequently a series of puffs of gas pass to the burner 13 and are ignited by a pilot burner not shown. When the pressure in chamber 3 is reduced the valve 8 recloses and the cycle is repeated. When valve 8 is closed the gas remaining in the conduit 12 deflects the diaphragm 14, the lower side of which is connected to chamber 3. When the valve 8 opens, pressure on the two sides of the diaphragm 14 is equalized and the diaphragm regains its normal position. Movement of the diaphragm in regaining this normal position forces more gas past the valve 8, the amount depending on the movement of the diaphragm which depends on the pressure in conduit 12 immediately preceding the opening of the valve 8. This regulates the supply to flasher 1 and maintains constant the number of flashes in each group. Other embodiments are described in which (1) the diaphragm 14 is situated in the casing 1 below but rigidly connected with diaphragm 2, and (2) the pipe 18 leads, through a throttle, to the underside of the diaphragm in flasher 11. The flashing may also be adjusted by controlling the lost motion between the valves and diaphragms of the flashers.

Abstract: 570,407. Heating-vessels. KOOPERATIVE FORBUNDET FORENING U.P.A. June 11, 1943, Nos. 9409 and 9410. Convention dates, May 28, 1942, and Aug. 18, 1942. [Class 66] [Also in Group VI] Apparatus for extracting fruit juice by means of steam comprises a frame consisting of an annular member 4 having an external projection for supporting it on the rim of a preserving pan 1 and connected by depending bands or rods 3 with a ring 2 or plate 10, for supporting a juice pot 9, a juice filter 6 being supported by an inwardly-directed flange 5 on the member 4 or by the inwardly-bent upper ends 5<1> of the rods 3. The member 4 is shaped to receive the lid 7 of the pan 1 and is provided with handles 8. The bands or rods 3 may be surrounded by one or more further bands to protect small juice pots. In use, water is boiled in the bottom of the pan and the steam acts upon the fruit on the filter, the juice dropping into the pot 9. When the pan is to be used for bottling fruit, the frame is removed and the usual bottle support inserted. The ring 2, or a central opening in the plate 10, is preferably adapted to pass over the bottle support so that all the parts can be stored in the pan. Alternatively, the perforated plate 10, or a flat perforated plate resting loosely on, or fixed to, the lower end of the frame formed with a ring 2 may be used to support the preserving glasses or bottles and the usual bottle support dispensed with. Clamping means for the bottles may be carried by the rods 3.

Title: Improvements in or relating to the art of polymerization and method of polymerizing vinylidene-group-containing liquid monomeric compounds
IPC: C08F2/22
Filed: 1946-03-27
Abstract: Monomers containing a vinylidene group such as vinyl chloride or bromide, vinylidene chloride and acrylonitrile are polymerized in a liquid state in an inert liquid medium, such as water, containing a dissolved polymerization catalyst such as potassium or ammonium persulphate or sodium peracetate but no emulsifier or like foreign ingredient, the medium being agitated so as to suspend the monomer in small globules, the temperature being between 25 DEG  and 100 DEG  C. and the pressure being kept at a value not substantially higher than the saturated vapour pressure of the monomer.  The resulting granular polymer is insoluble in the monomer and the catalyst is insoluble in both monomer and polymer. Other monomers such as ethyl b  - chloroacrylate, dimethyl maleate, diallyl succinate and isobutyl methacrylate may also be present.  From 1 to 15 per cent of a plasticizer such as dibutyl phthalate may be added to the reaction mixture.  After separating the globules of the resulting polymer the liquid which remains may be employed as the inert liquid medium for another batch. Specifications 410,132, 518,704 and 579,881 are referred to.  The Specification as open to inspection under Sect. 91 comprises also the use of styrene, vinyl acetate or butyrate, vinyl ethyl ether, vinyl isobutyl ether, methyl acrylate and methyl and isobutyl methacrylates.  This subject-matter does not appear in the Specification as accepted.
