Title: Method and apparatus for sterilising containers
Inventor: MOSSE RICHARD WOLFGANG EMIL
IPC: A61L2/04
Filed: 1961-05-17
Abstract: 943,150. Sterilizing containers. METAL BOX CO. Ltd. April 19, 1962 [May 17, 1961], No. 18008/61. Heading A5G. A method of reducing the level of bacterial contamination of an open-mouthed container for food or liquids sensitive to bacterial contamination consists of sterilizing the container by igniting in the container an explosive mixture of gases, thereby to subject the interior surface of the container to rapidly generated heat and immediately thereafter inserting food or liquid into the container and effecting closing of the container. Also, an apparatus for carrying out the method comprises a conveyer arranged to move an open-mouthed container to a filling and closing machine and at a position immediately prior to that at which the container is moved into the machine, means to provide an explosive mixture of gases in the container, and means for effecting ignition of the explosive mixture in the container. The method of the invention is particularly suitable for sterilizing plastic coated or waxed paper containers, which cannot be heated directly. In an embodiment, the explosive mixture of gases is created in the container by introducing an inflammable gas into air contained in the container. Ignition means may be present so that ignition is effected when the gas/air mixture reaches flash point. In another embodiment, a predetermined volume of an explosive mixture of gases is introduced into the container. The means for effecting ignition may comprise a radiant heat appliance supported for movement into and out of the container. Alternatively, the ignition means may comprise a device, of known form, for producing a spark capable of igniting the explosive mixture. In the Figure, an openmouthed waxed paper carton 1 is placed on a support or conveyer 2 so that an igniting device can then be moved, preferably automatically, into the carton through the mouth thereof. The igniting device is a radiant heat appliance having an electrically heated platinum spiral 3. Town gas is slowly admitted through a pipe 11 into the carton and mixes with the air present. The latter is augmented by compressed air delivered through a pipe 12 via a cotton wool filter 14. The admitted gas and air may be diverted by means of a baffle 13. After ignition at the flash point, the carton is filled with food or liquid and then closed.

Patent GB-872044-A (GB)
Title: Improvements in electrical circuits for use with temperature-sensitive or flame-sensitive means
Inventor: COLLINS JACK BERTRAM
IPC: F23N5/14
Filed: 1956-06-13
Abstract: 872,044. Electric flame and temperature alarms. GRAVINER MANUFACTURING CO. Ltd., and WILKINSON SWORD Ltd. Aug. 29, 1957 [June 13, 1956], No. 18264/56. Class 118. A temperature and flame-sensitive alarm comprises a gas-discharge valve with a predetermined bias to maintain the valve non- conducting; temperature- or flame-sensitive variable resistance means passing a predetermined current for a particular flame or temperature condition and a load developing a voltage proportionate to the current for triggering the discharge valve. The flame &c. sensitive device FW is supplied by D.C. and develops a voltage over R 1 . This is rectified by the quadruple circuit and applied to the trigger electrode of a Z900T through R 2 . The predetermined bias comes from the junction of R 3  and R 4 . When the device FW loads R 1  and thus fires the valve relay A is energized by repeated firing of the valve and consequent recharging of C 6 . In a modification a parallel resistor R 7 , normally switched manually to change the operating temperature, is switched in by relay A, reduces the operating voltage and the tube ceases to fire and thus relay A opens. The cycle then recommences. This gives a flashing warning light. If the temperature is sufficiently high for the parallel load R 1 , R 7  to trigger the valve then a continuous warning is given. In a further modification the relay switches A 2  and the capacitor C 1  is shunted to drop the triggering voltage. The time taken for C 8  to charge through R 6  will depend on the applied voltage, thus the frequency of flashing depends on the current through the load resistor R 1  which is governed by the temperature of FW. The circuit may again be modified by supplying A.C. to the discharge valve instead of using R 5 , C 6  to control oscillation of the valve. Specification 801,660 is referred to.

Title: New sulphonic acid and process for its production
IPC: C07D213/76
Filed: 1966-04-28
Abstract: The invention comprises 3-hydroxy-2-imino-1(2H)-pyridine sulphonic acid.  It may be obtained, together with 2-amino-3-pyridinol, by reacting furfurol in an aqueous medium with chlorine or a compound yielding chlorine under the reaction conditions, e.g. NaOCl, the molar proportion of the two components being 1:1-1.5, reacting the reaction mixture with sulphamic acid or a salt thereof at a pH above 0.5 at a temperature within a range limited by the crystallization point of the reaction mixture and the boiling-point thereof, either isolating the precipitated 3-hydroxy-2-imino-1(2H)-pyridine sulphonic acid monohydrate and, if desired, hydrolysing it into 2-amino-3-pyridinol, or hydrolysing the precipitated monohydrate without previous isolation from the reaction mixture into 2-amino-3-pyridinol.  The chlorination reaction is preferably effected at a pH below 6 and at below 40 DEG  C. in the presence of a chlorination catalyst, e.g. NaBr, KBr or a molybdenum salt and the subsequent reaction with sulphamic acid is preferably effected at between 0 DEG  and 10 DEG  C. The 2-amino-3-pyridinol is obtained in the form of its sulphuric acid salt by heating or storing the sulphonic acid monohydrate or the reaction mixture containing it and the free base may be liberated from the salt by the addition of an acid binding agent, e.g. concentrated NaOH solution followed by filtration, or it may be isolated by making the aqueous reaction mixture weakly alkaline and then extracting, e.g. with ether.  The desired pH value in each reaction stage of the main process may be attained by adding compounds having a basic or acidic reaction as appropriate.

Title: Improvements in and relating to apparatus for the compensation of the error in traverse caused by the oblique position of the horizontal axis of the trunnions of a gun erected on a swaying foundation
IPC: F41G5/16
Filed: 1920-07-05
Abstract: 146,483. Krupp Akt.-Ges., F. Dec. 12, 1917, [Convention date]. Sights and methods of sighting. - Relates to means for applying the traverse correction (#) in accordance with the inclination of the trunnion axis (gamma) and the angle of gun elevation (a), and consists in providing mechanism which operates according to the known law # = ay and which enables the corrected angle of traverse to be applied to a gun mounted on a swaying platform, as for example on board ship. Fig. 1 shows one construction in which a support E<3> at a distance from the gun B is traversed by a hand-wheel G through the same angle as the gun is traversed by a handwheel C. For this purpose the hand-wheel G drives Marks g<3>, g<2> which follow the indications of coarse and fine pointers e<2>, e<1> that are moved synchronously with similar pointers d<1>, d<2> set when the gun is trained. The prescribed angle of gun traverse is shown by a pointer R moving over a dial S, the pointer being driven from the training-rack b<1> through a differential gear r<1>. The support E<3> carries a telescope or spirit level F which is turned on an axis perpendicular to the trunnion axis a' to keep it horizontal by a handwheel H which drives a friction disk J through an angle proportional to the inclination of the trunnion axis. Engaging with the disk J is a roller J<2> which is set radially in accordance with the range angle by means of a hand-wheel K and scale k<3>. The roller J<2> therefore receives from the disk a rotary motion proportional to the product ay. This correction is through an electrictransmitter J<4> passed on to a receiver N connected to a pointer n<1> near the gun. By following this pointer with a mark p<1> driven by a handwheel P<2>, the pointer R is moved through the differential gear r<1> bv an amount equal to the traverse correction. By operating the hand-wheel C to bring the pointer R back to the prescribed angle of traverse, the correction is applied to the gun. In a modification, Fig. 2, the telescope F for viewing the horizon is stabilized by a gyroscope F<2> and connected electrically to a pointerf<5>. By operating a hand-wheel J<8>, a mark i<7> is made to follow the pointer and convey to the friction disk J a movement proportional to y. Further, a telescope V directed on the target conveys the angle of traverse to the gun through a differential gear w<2> and coarse and fine transmitters W, W<1> the correcting movement of the roller J<2> being imposed upon the transmitters through the differential gear.
