Patent GB-345190-A (GB)
Title: Improvements in or relating to the preparation of chlorine dioxide
IPC: C01B11/02
Filed: 1930-08-26
Abstract: Chlorine dioxide is prepared by the action of sulphuric acid on prepared lumps of a mixture of a chlorate with substances which are inert with regard to chlorates and sulphuric acid such as gypsum or pumice.  Inert gases may be introduced during the reaction and these gases may be charged with gaseous organic reducing agents such as formic acid or formaldehyde. Alternatively, the inert gas may be formed in situ by adding salts which react with sulphuric acid to the mixture of chlorate and inert substance.  Catalysts such as manganic oxide, or the oxides of vanadium, iron or osmium may also be added. Organic reducing agents such as oxalic acid, formic acid, or carbohydrates may be added to the prepared lumps and sulphuric acid. According to examples, (1) potassium chlorate is made into a paste with gypsum and water, lumps of the resulting hard product being treated with sulphuric acid; (2) sodium bi-carbonate or chalk is added to a mixture of potassium chlorate and gypsum which is treated according to example (1); (3) lumps of sodium chlorate and gypsum made as in example (1) are treated with sulphuric acid while air charged with formaldehyde vapour passes through the reacting mixture; (4) a small proportion of osmium oxide is added to a mixture of potassium chlorate and gypsum, further treatment being as in example (1); (5) pumice is saturated with a solution of potassium chlorate, the dried product being treated with sulphuric acid.
Patent GB-1322997-A (GB)
Title: Circuits for producing delayed pulses
IPC: H03K5/04
Filed: 1971-04-19
Abstract: 1322997 Transistor pulse delaying circuits; colour television SONY CORP 19 April 1971 [2 April 1970] 25411/71 Headings H3T and H4F In a delayed pulse producing circuit comprising a transistor 1 and a D.C. bias to operate the transistor in a predetermined conductive condition in the absence of an input pulse Ph and to cause an increased current to flow in the transistor with the supply of the input pulse, the charge of charging and discharging means 3 by the increased current causes the transistor to be non-conductive at the end of the input pulse and thereafter the discharge of the means 3 returns the transistor to the predetermined conductive condition. The circuit further includes a load for the transistor consisting of first and second parts 4, 5, circuit means 14 operative as a series connection of a diode (14B, Fig. 3, not shown) and a constant voltage source (14A) connected between the first and second parts 4, 5 of the load, the diode (14B) assuming a non- conductive condition in response to an increased potential at an electrode of the transistor when the transistor is non-conducting, and means for deriving a pulse delayed by the duration of the input pulse from the load in response to the increased potential. The transistor 1 is D.C. biased in a predetermined conductive condition in the absence of an input pulse Ph. An input pulse at 11 turns the transistor 1 on more. The transistor 14 which functions as the diode (14B) in series with the constant voltage source (14A) then becomes forward biased and feeds current to the collector of the transistor 1 to maintain the output constant (between times t 1 , t 2 , Fig. 2C, not shown). Capacitor C3 charges and at the end of the input pulse Ph the transistor 1 turns off to produce an output pulse (P2). The duration of the output pulse is determined by the time taken for the capacitor C3 to dsicharge so that the transistor 1 switches to the predetermined conductive condition. The pulse generator may be used with a colour synchronizing system of a colour T.V. receiver. A parallel tuned circuit 21 is resonant with a burst signal frequency and the duration of the output pulse (P2) from transistor 1 is made to agree with the duration of the burst signal. A switching diode 16 is non-conductive in the absence of horizontal synchronizing pulses at input 11. When an output pulse (P2) is obtained from transistor 1 diode 16 is turned on only in the duration of a burst signal inserted in the back porch of a horizontal blanking period contained in the composite colour television signal supplied from terminal 19. The burst signal from 19 is derived as an output from 23 via transistor 20, diode 16 and transistor 17. The circuit may be constructed in integrated circuit form.

[Also in Division B8] A device for dispensing a predetermined number of tablets or capsules comprises a hopper 22 surrounding an inclined motor-driven plate 34 provided with a number of slots 38, and a cover plate 46 of such a size as to permit the tablets to fall into the slots. The tablets slide to the inner ends of the slots and fall through an aperture 48, closing a switch to advance a uniselector counter. Tablets in the outermost position are dislodged by a flip spring 60 at one point of the plate's rotation so as to prevent jamming. The predetermined number is set up on rotary switches and when the uniselector counter attains this number it resets to zero and cuts off the drive motor after a time delay sufficient to allow the last tablet to clear the switch. Plates and time-delay circuits are changeable to allow for different sized tablets or capsules.

Abstract: 601,481. Ammunition. SPEECHLY, G. K., ANSELL, W. R., and SMITH, F. E. Oct. 2, 1945, No. 25642. [Class 9 (i)] Means for attaching a projectile or sabot having a skirt driving-band to a cartridge case comprises an internallythreaded ring secured within the mouth of the cartridge case and engaging a corresponding thread on the skirt driving band, the said ring being weakened so as to rupture on firing.

Patent GB-948784-A (GB)
Title: Process and apparatus for alteration of the charging state in disperse systems
IPC: B01J13/00
Filed: 1960-07-25
Abstract: In a process for varying the charging state of dispersed systems of inorganic and/or organic origin for the purpose of sterilizing and utilizing the phases or substances contained therein, the dispersion systems are arranged concentrically between electrodes of carbon, where they are subjected to impulse-like discharged direct current fields, from high tension condensers.  The process is effected with apparatus comprising several parallel mounted capacitors dischargeable by means of mercury reversible switches over carbon electrodes connected with them which serve to produce steep direct current impulses, the mercury reversible switches disconnecting the capacitors from the charge lead shortly before the commencement of discharge.  High current amplitudes may be produced by causing the capacitors to discharge at the same time oscillatorily at high frequency and/or aperiodically in a very short time.  The energy necessary for the attainment of the separation effect, the gradient of the discharge curve, the frequency of discharge, the strength of the magnetic field and a number of impulses in a cross-section of the material to be treated, is a function of the qualities of the system dependent on the desired effect.  Examples describe (1) the separation of unwanted scums in centrifuging and filtration processes, (2) the extraction of sub-strata from animal and plant material, (3) the production of foams and emulsions, (4) the increase or decrease in the activity of enzymes, and (5) the manufacture of protein concentrates.  Under (2) meat or fish is disintegrated, forced between concentrically arranged carbon electrodes.  Following discharge the muscle threads contract and liberate the fluid they contain.  After impulse treatment the materials separated into the phases aqueous, oleaginous and solid. A further development of this procedure sterilizes animal and plant substances and splits them into aqueous and oleaginous phases and solids for the extraction of substances from the separated phases.
