Title: Improvements in or relating to the automatic regulation of steam generation in high pressure steam power plants
IPC: F22B3/04
Filed: 1925-05-09
Abstract: 234,093. Siemens - Schuckertwerke Ges. May 13, 1924, [Convention date]. Controlling superheat.-In a steam generator in which steam is generated at critical pressure, throttled down to working pressure and superheated, the feed-device and the firing and throttling members are so controlled automatically that the pressure in the generator is maintained near the critical pressure, and at all stages, the temperature is maintained at such a value that an unstable separation of steam and liquid cannot occur. The operation of the feed pump 1 of a boiler 2 supplying steam through a superheater 4 to a turbine 6 is controlled by a device 13 acted upon by the steam pressure. The supply of fuel to the furnace 10 is controlled by a thermostat 15 in the steam pipe. The throttle valve 3 between the boiler and the superheater is so controlled by a pressure operated device 11 that when the pressure decreases the valve is opened, and when the pressure rises the valve is closed. The throttle valve may be controlled by the pressure in the generator.

Abstract: 400,626. Television. ELECTRICAL RESEARCH PRODUCTS, Inc., 195, Broadway, New York, U.S.A.-(Assignees of Gray, F. ; 243, West 101st Street, New York, U.S.A.) April 27, 1932, No. 12146. Convention date, May 21, 1931. [Class 40 (iii).] In a scanning device for television &c. systems of the kind comprising a number of reflecting strips helically disposed about an axis of rotation and illuminated by a laterally located and controlled linear light-source, the reflecting surfaces are so constructed and arranged that the image may be viewed by direct observation of the mirror helix and the lightsource may have a dimension smaller than that of the helix measured along its axis. In the construction shown in Figs. 1 and 2 the reflecting strips 10 . . 29 of the helix 5 are mounted on a common shaft 30 with equal angular spaces between adjacent strips, each of which has one edge bevelled and polished to form a reflector, while the opposite edge and end are coated with black paint or similar material. The inclination of the bevelled sur. faces increases progressively towards the extreme strips so that, as the latter successively become operative, their combined effect is equivalent to that of a concave mirror. The bevelled edges may be disposed all at the same distance from the shaft 30 as shown diagrammatically in Fig. 3, or at progressively increasing distances therefrom as shown in Fig. 4. According to the first of these arrangements the reflecting edges are flat, and in the second arrangement spherically concave ; while according to further modifications the reflecting edges may be convex, parabolically concave, or be formed with a series of convex corrugations. A shield 9 protects the eyes 8 of the observer from the direct light of the source 6.

Title: Apparatus for determining correct pyrometer readings with steam or other interference present
IPC: G01J5/60
Filed: 1972-03-15
Abstract: 1387060 Radiation pyrometer USS ENGINEERS & CONSULTANTS Inc 15 March 1972 [25 March 1971] 12158/72 Heading G1A In the determination of the temperature of a surface e.g. hot rolled steel by radiation pyrometry when radiation from the surface is attenuated or scattered away by an interfering substance e.g. steam, spray, dust or smoke, and would cause erroneous measurement, there are provided first and second detectors viewing the same area of the surface, the second detector having a different wavelength response characteristic from that of the first detector and having an error in its output signal caused by the interfering substance in a substantially constant ratio, within the temperature range of interest, to the error in the output signal of the first detector, and the output signals of the two detectors are combined in such a way as to obviate the errors caused by the interfering substance. The detectors may be aligned side by side to view the surface, or more accurately, as in Fig. 1, may be associated with a beam-splitter 10. In Fig. 1, the detectors 16, 20 are a total radiation pyrometer and a silicon cell respectively. The pyrometer 16 has a substantially linear response and its output VR may thus be used directly. The silicon cell output V S  has to be linearized at 24 before use, which results in a curve representing, in general three times its previous value i.e. 3V S . It is also found that the error due to the interfering substance with the silicon cell, is one third that for the total radiation cell, so that a true measure of temperature may be obtained by taking VTRUE = (3V S -V R /2). This is carried 2 out with voltage divider 32 and recorder 30. Indicator 34 is provided to indicate e.g. actuate an alarm when the interference is beyond acceptable limits, determined by evaluating the difference between the outputs of pyrometers 16, 20 or as in Fig. 1, of the output of pyrometer 16 and a third (at potentiometer 32) of the output of linearizer 24. It may be necessary to linearize the outputs of both pyrometers.

Title: Process for preparing organic pyrophosphates
IPC: C07H1/02
Filed: 1963-03-29
Abstract: Organic pyrophosphates, of formula <FORM:1007770/C2/1> are prepared by reacting together, in the presence of an inert solvent, a phosphite, a phosphate, and a mono- or di-halogen derivative of of an active methylene compound, according to the equation <FORM:1007770/C2/2> wherein R1 is alkyl or aralkyl; R2 and R3 are alkyl, aralkyl, or aryl which may be substituted; R4 is hydrogen, alkyl, aralkyl, or aryl which may be substituted; R5 is a radical of an organic hydroxy compound, or a phosphate ester radical; A is a highly electronegative radical; X is halogen; and Y is -NHR6 or -OR6, wherein R6 is hydrogen, alkyl, cycloalkyl, aralkyl, or aryl. Preferred inert solvents, which are defined as being those solvents that are inactive to the enol-phosphates formed by the Perkow reaction, are ether, benzene, dioxane, N-dimethyl-formamide, and tetrahydrofuran; water is said not to inhabit the reaction, and it may, when appropriate, be performed in aqueous solution. Preferred halogenated active methylene compounds are bromine or chlorine substituents of cyanoacetamide, malonamide, methyl-, ethyl-, n- or iso-propyl-, n- or iso-butyl-, or phenyl-cyanoacetate, or N-cyclohexyl cyanoacetamide. Examples are given by preparation of: (1) and (4) dimethyl diethyl pyrophosphate; (2) tetraethyl pyrophosphate; (3) diethyl di-n-butyl pyrophosphate; (5) tetra-(p-nitrophenyl)-pyrophosphate; (6) and (7) tetraethyl pyrophosphate; (8) dibenzyl-5-adenosine diphosphate, which was converted to monobenzyl-51-adenosine diphosphate, and thence to 51-adenosine triphosphate. 21-31-o-isopropylidene guanosine was phosphorylated with the product of Example (5), tetra-(p-nitrophenyl) pyrophosphate, to give guanosine-51-phosphate.  The active methylene compounds may be filtered off after reaction, re-halogenated, and used again.  The process of the invention is useful in preparing nucleoside polyphosphates, and carbohydrate polyphosphates, and also several phosphorylating agents such as tetraethyl- and tetra-(p-nitrophenyl)-pyrophosphate

Abstract: 1296620 Tractor/trailer brakes STEYRDAIMLER-PUCH AG 4 May 1971 [29 May 1970] 12926/71 Heading F2F A device for applying trailer brakes is actuated by the tractor brake pedal 1, which through a linkage 2, 4 and cam 7 causes a control valve 8 to move leftwardly so that hydraulic pressure in the trailer brakes is released through a transfer conduit 12 connected thereto, through bores 26, the hollow interior of valve 8 and a drain port 13, the trailer brakes then being applied by springs. As the hydraulic pressure in the trailer brakes is lowered the pressure acting on valve shoulder 18 is correspondingly decreased and valve 8 again moves to the right. When pedal pressure is relieved valve 8 moves further right under the action of spring 9 to connect discharge conduit 11 communicating with a sump and cylinder 22 to conduit 12 by way of passage 11a and the annular space between valve 8 and a shoulder 19 to release the brakes. The pressure on shoulder 18 is thereby increased and valve 8 returns to its original position. With a sliding shut off valve 20 in the position shown hydraulic fluid passes from port to a port 14 communicating with an auxiliary device. Leaks at valve 8 are compensated by a pressure accumulator comprising cylinder 22, springs 23 and piston 24 as valve 8 moves rightwardly. When the accumulator is empty a control valve 25 is moved by piston 24 to an extreme right hand position connecting a passage 28 to the passage 11a and a passage 27 via the central bore of valve 25 to the drain port 13. The pressures at the ends of valve 20 are unbalanced so that it moves leftwardly to cut off communication between ports 11, 14. Hydraulic pressure from the pump then recharges accumulator 22-24 through a check valve 21, whereafter valve 20 returns to its original position.
