Title: Sterilisation of a environment with ozone and increased humidity
Inventor: JENNINGS JAMES ROBERT
IPC: F24F8/80
Filed: 2009-03-12
Abstract: A method of sterilisation, sanitisation and/or decontamination comprises the steps of producing a humidified environment having a relative humidity which is higher than ambient humidity; discharging ozone into the humidified environment; maintaining the ozone level at a concentration that will achieve the required degree of decontamination and sterilisation of the humid environment; reducing the relative humidity of the decontaminated and sterilised environment and passing the environment through a catalyst to reduce the concentration of ozone to a predetermined level. The ozone level may be reduced by introducing a hydrocarbon containing a carbon-carbon double bond, such as an alkene or a cyclo-alkene to the environment. Apparatus for carrying out the method is also claimed.

Title: Peripheral device operation method, peripheral device and host
Inventor: LI JILIN
IPC: G06F9/445
Filed: 2008-05-08
Abstract: An operation method of peripheral device includes setting up connection of peripheral device to host, directly loading firmware of said peripheral device from said host, and operating said firmware by said peripheral device. The requirement of the peripheral device to non-volatile memory capacity is decreased. By pre-storing the firmware of the peripheral device in the host, the requirement of the peripheral device to non-volatile memory capacity is decreased. And it is not necessary to download the firmware in the non-volatile memory frequently when producing and debugging the peripheral device. Only loading the firmware of the peripheral device from the host directly is needed, and the efficiency is improved.

Title: Improvements in and relating to voltage regulators for dynamoelectric machines
IPC: H02P9/10
Filed: 1932-04-14
Abstract: 399,864. Automatic regulation. INTERNATIONAL GENERAL ELECTRIC CO., Inc., 120, Broadway, New York, U.S.A.-(Assignees of Allgemeine Elektricitats-Ges.; 2, Friedrich Karl-Ufer, Berlin.) April 14, 1932, No. 10719. Convention date, April 14, 1931. [Class 38 (iv).] On the occurrence of short-circuit conditions a resistance is inserted in series with the voltage responsive coil of an automatic regulator of the voltage of a dynamo-electric machine so that the regulator operates to maintain the voltage at a lower value than that obtaining before the short-circuit, the excitation of the machine during the short-circuit being unaffected. The circuit of the voltage coil f of the quick-acting regulator shown contains regulating resistances R1, R2. In one form, Fig. 1 (not shown), an under-voltage relay excites a time-delayed relay which frees a latch T, Fig. 2, to cause the normally short-circuited resistance R2 to be thrown into circuit under short-circuit conditions of the generator E. The regulator A having reached its limiting position before this operation due to the fall of system voltage is not operative to change the excitation but will regulate to a lowered voltage on removal of the short-circuit. In a modification, Fig. 2, a current relay Y energized from the system operates on short-circuit to open the circuit of the releasing coil O and energize a timedelayed relay f which energizes an automatic device g closing a contact h in the releasing coil circuit and opening it again after a time interval greater than the normal duration of shortcircuits. The fall of the current relay Y during the period of closure of the contact h effects the release of the latch T. This arrangement permits of choosing the moment at which the adjustment of the regulator shall be altered. Specification 238,513, [Class 38 (iv), Electric supply and transmission systems &c.], is referred to.

Abstract: 797,320. Ligaturing appliances. KAMMER, K. April 11, 1956 [April 14, 1955], No. 10979/56. Class 81 (2). A device for tying ligatures on arteries comprises means for gripping the artery, applying the loop to it and tightening it and cutting the thread, these operations being performed by gripping and releasing a single handle. The mechanism is enclosed in a cylindrical body 1 and is actuated by a hand lever 7, pivoted at 71. When this is gripped, initially a roller 8 bears on the gripping arms 5, 6 to hold the artery and subsequent inward movement causes engagement with the end of a lever 22, to withdraw a detent to allow a slide 13 to be moved downwards by a spring 15 and this carries a subsidiary slide member 32 carrying a thread holding head 16. Continued movement causes a subsidiary lever 26 to bear against and release a latch and permit the lower sleeve 32 to be drawn upwards and, with it, two hooks which engage the ends of the loop and draw a first knot tight. Thereafter, as the handle is released, two pins 33, on which the second knot has been placed, are withdrawn so that continued upward movement of the hooks draws the knot tight. Finally, towards the end of the upward movement of the slide 13, two knives 46, mounted on studs 47, 48 in suitably shaped guide slots to give a draw cut action, are drawn upwards to sever the thread. Reference has been directed by the Comptroller to Specification 759,388.

Title: Method of treating raw phosphate and other materials containing insoluble calcium phosphate
IPC: C05B11/04
Filed: 1927-04-25
Abstract: 282,704. Liljenroth, F. G. Dec. 31, 1926, [Convention date]. Void [Published under Sect. 91 of the Acts]. Cements.-Raw calcium phosphate is treated by a wet method to give phosphoric acid or a soluble salt thereof, and a hardly soluble or insoluble calcium salt which is mixed with silica, clay, or other aluminiferous material and heated to drive off the acid radicle from the calcium salt and leave a cement clinker. The regenerated acid, free or as a salt, is used to treat further phosphate. Silicon tetrafluoride is led into an aqueous suspension of calcium phosphate; silica and hydrofluoric or hydrofluosilicic acid are formed, which react to give phosphoric acid and calcium fluoride. Clay, iron oxide and silica are added to the residue after filtering off the acid, and the whole burnt to yield a cement clinker, the fluoride being driven off as silicon tetrafluoride. Steam may be blown into the lower hotter part of the furnace, and hydrofluoric acid so formed becomes silicon tetrafluoride, which may be led to phosphate directly or after decomposition as hydrofluosilicic acid. Raw phosphate is treated with sulphuric acid, and the calcium sulphate separated, mixed with sand, clay and bauxite, and calcined in an oxidizing atmosphere preferablv with coke to facilitate the evolution of sulphur dioxide, from which sulphuric acid may be prepared; or the raw phosphate may be leached with an acid having a soluble calcium salt, e.g. nitric or phosphoric acid, and calcium sulphate is precipitated by an alkali metal or ammonium sulphate.

Abstract: 1483971 Winding and unwinding predetermined web lengths ARMCO STEEL CORP 17 March 1975 [22 March 1974] 11011/75 Heading B8R Apparatus for winding or unwinding predetermined lengths of web 12, Fig. 1, on to or from a web roll 19 comprises a pair of pulse generators 22, 23 associated with a roller 15 which is driven by the web and with the web roll 19, respectively, the generators being coupled to counters 26, 28 such that for a "zero" count the counter 26 enables a comparator 27, having written into it a pair of values, which are compared with the pulses applied to the counter 28. Successive comparison and coincidence of the pulses in the counter 28 leads first to slowing down and then to stopping of the web roll. In operation the required length of wound web is expressed in terms of R 0 , Fig. 2 (i.e. diameter) which is applied to a diameter input 24. The position at which the web roll is to be slowed down is expressed by R 1 . Both values are passed by the input 24 to a conversion circuit 25 which expresses the values R 0 , R 1  in terms of arc lengths S 0 . The values of So are applied to the line down-counter 26 which provides a "zero" count whenever the pulse generator 22 provides a pulse in consequence of the roller 15 having been formed by the web by an amount S 0 . Simultaneously the generator 23 produces a pulse representative of the angle A corresponding to a particular radius R and the instant value of the angle A is compared with the preset values A 0 , A 1 . When coincidence occurs at A 1 , the comparator 27 issues a slow down signal on its output 42. Subsequent comparison coincidence associated with the angle A 0  results in the emission of a stop signal on the output 43.

Abstract: 1,063,621. Heating gases. COMMISSARIAT A L'ENERGIE ATOMIQUE. March 16, 1964 [March 29, 1963], No. 11016/64. Heading H5H. [Also in Division H2] In a magnetohydrodynamic generator installation the hot gases from the combustion chamber are passed through a device for Joule heating the gas, without arc formation, to produce alternate hot and cold regions before interacting with the magnetic field across the generator duct to generate power. The Joule heating device (Fig. 3, not shown) comprises a number of pairs of electrodes (10), (12): (14), (16) spaced apart along the length of the duct and supplied with time varying voltage from either an A.C. generator (18) or a D.C. generator having an associated commutation arrangement. By synchronizing the output of generator with the speed of gas flow v, such that a region of gas subject to high voltage at electrode (10) will have moved opposite electrode (14) when this is at high voltage, a striated gas flow consisting of alternate regions of relatively hot ionized gas and relatively cool un-ionized gas is produced at the input to the generator duct. The spacing p between the electrodes will equal the sum of the lengths of the two regions of gas. In further modifications rectifiers may be used in the supply leads from the single phase alternator or a three-phase system may be used. In an alternative device, a duct (70), Fig. 8 (not shown), is of rectangular section and consists of electrodes (72) comprising plates of zirconia, spaced apart by laminated zirconia insulators (74). Connections are made to the electrodes by means of a sheet or foil of refractory metal and both the electrodes and insulators are supported by refractory bricks. The top and bottom walls of the duct are also made from bricks of zirconia which are force cooled. The diverging duct (96) is constructed with force cooled zirconia walls and has longitudinally extending electrodes (98).
