Title: Apparatus for extinguishing or preventing fires
IPC: A62C3/06
Filed: 1943-12-08
Abstract: 577,188. Fire-extinguishing. CARDOX (GREAT BRITAIN), Ltd. (Cardox Corporation). Dec. 8, 1943, No. 20533. [Class 47 (ii)] Apparatus for extinguishing or preventing fire in liquids stored in tanks or other enclosures or flowing over surfaces is designed to project a flat sheet or curtain of solid and gaseous carbon - dioxide in layers above the surface of the liquid. As applied to a conventional quench or dip tank provided with internal partitions and a counterweighted cover or covers 21, Figs. 3 and 4, an elongated slot 31 is cut in one or more of the outer walls 13 of the tank across its full width and above the liquid level 50. An expansion chamber 36 with closed ends is secured over the slot and receives a carbon-dioxide supply pipe 29 formed with restricted orifices 57 spaced along its length and pointing away from the slot 31. When liquid carbon-dioxide is admitted to the pipe 29 it expands in the chamber to fill it with a mixture of gas and snow, which is segregated into layers and discharged through the slit 31 as a thin sheet parallel to and above the surface of the liquid, cooling and diluting the combustible or burning vapours in the upper part of the tank and preventing ingress of air to the vapour space immediately above the liquid. Preferred relative values of the vapour pressure of the stored liquid carbon-dioxide, the size of the pipe 29 and orifices 57, the spacing of the orifices from the wall of the chamber 36 and the height and area of the slot 31 are specified. As applied to a cylindrical storage tank 60, Figs. 10 and 11, the expansion chamber 65, housing the carbon-dioxide pipe 70 and embodying the slot 68, is secured in ring form to the inner surface of the tank near its upper end. A similar discharge device 73 is mounted on the wall or dike 63 enclosing the overflow space 61 surrounding the tank. Further discharge devices 75 are mounted outside the tank near its top and at one or more intermediate points, in order to project an extinguishing curtain over the outer surface of the tank, and are carried by brackets 76 so as to leave gaps through which any liquid which overflows from the tank may run. Liquid carbon-dioxide for supply to the extinguishing devices preferably is stored at constant sub-atmospheric temperature as described in Specification 519,789. The discharge apparatus may be mounted on floats or otherwise in order to compensate for fluctuations in the liquid level in the tank. Specification 566,979 also is referred to.

Abstract: 499,363. Delivering materials from hoppers. TRIGGS, W. W. (Bates International Bag Co.) July 13, 1938, No. 20805. [Class 78 (i)] - A hopper is fitted with centrifugal delivery means associated with other delivery-means such as a worm. Figs. 1 and 2 show a worm 12 working in the rounded bottom of the hopper 10 with little clearance between the blades and the walls, so as to deliver material to the chamber 16 traversed by the centrifugal blades 28 which throw the material to the periphery of the casing with a de-aerating effect and then deliver to the spout 29. A rounded surface 19 revolving with the blades diverts material towards the periphery of the chamber and the latter is open to the hopper above the axis of the worm so that excess material can escape back into the hopper. The peripheral wall of the upper part of the chamber also is deepened between the points 30 and 31 to promote the escape of the excess material. In a modified construction the worm 12 is driven through a clutch so that it can be started and stopped independently of the blades, and a hand-operated sliding valve is provided in the spout 29.

Title: Manufacture of photo-luminescent glass
IPC: C03C4/12
Filed: 1935-07-22
Abstract: 460,210. Glass manufacture. I. G. FARBENINDUSTRIE AKT.-GES. July 22, 1935, No. 20810. Convention date, July 21, 1934. [Class 56] Glass which becomes luminescent when exposed to light of short wavelength is made by adding an " exciter " metal to a phosphate glass in which the proportion of P2O5 is not less than 20 per cent of the acid constituents, the batch being fused under reducing conditions. The " exciter " consists of a heavy metal such as cadmium, tin, bismuth, or copper, and the reducing condition may be obtained by the addition of a reducing agent, such as urea, to the batch or by exposing the fused mass to a reducing flame. The glass thus obtained may be flashed with a glass which emits luminescence of a different colour, or with an opalescent glass. It may be used, also, for flashing an ordinary glass which is transparent to ultraviolet rays, the compound glass being suitable for the manufacture of electric discharge tubes. Compositions of mixtures for a number of glasses are given. in the Specification. For example, a batch consists of 1000 parts of H3PO4, 175 parts of BaCO3' 70 parts of Al2O3, and 55 parts of MgO, and to 10 kilograms of this batch, 100 grams of tin dioxide and 300 grams of urea are added. The glass made by melting this mixture when flashed with an opalescent glass, obtained by adding zirconium dioxide to the batch, gives increased light when used for the envelope of a low-pressure mercury vapour discharge tube.

IPC: G05B6/02
Filed: 1970-04-30
Abstract: 1,267,628. Automatic control. GENERAL MOTORS CORP. April 30, 1970 [July 22, 1969], No.20912/70. Heading G3R. In an electronic system by which an input variable is automatically controllable by two different variables dependent on the magnitude of the input variable, the magnitudes of the dependent variables are compared with reference values so that the difference corresponding to one dependent variable normally controls the input variable through an amplifier, the difference corresponding to the other dependent variable, however, being effective through a diode and the amplifier under certain conditions to over-ride control of the input variable. In Fig. 1, the supply of fuel from a source 22 to the combustion chamber 16 of a gas turbine is controlled by a by-pass valve 26 and a signal from a potentiometer 38 corresponding to the setting of by-pass valve 26 is compared with a signal from a potentiometer R12 representing a desired setting so that any error is effective through a feedback amplifier A1 to operate a motor 32 and thereby correct the position of the valve. A signal corresponding to gas turbine temperature, derived from a thermocouple 40 associated with a cold-junction 42, is compared with a signal from a potentiometer R22 representing a predetermined temperature so that any difference is applied to a feedback amplifier A2. The output of amplifier A2 is coupled through a diode D11 to the input of amplifier A1 so that if turbine temperature exceeds the predetermined value, the output of amplifier A2 is effective through diode D11 and amplifier A1 to over-ride the positional control of by-pass valve 26 and restore turbine temperature to the predetermined value. Modifications involve proportional plus integral control, a further diode to prevent saturation of amplifier A2 while not in control, and more than one over-riding variable, e.g. speed and temperature. Potentiometers R12 and R22 may be automatically controlled.
