Title: An improved method of regulating the working of high pressure steam generators
IPC: F22B37/00
Filed: 1927-12-13
Abstract: 282,657. Akt.-Ges. der Maschinenfabriken Escher, Wyss, et Cie. Dec. 24, 1926, [Convention date]. Controlling superheaters.- The heating of a superheater, is directly controlled in accordance with the position of the member controlling the steam supply from the generator and, for the purpose of completing this coarse regulation, the quality of the steam, i.e. its temperature or pressure or both, is used for further regulating at least one of the factors influenced by such coarse regulation. The generator K and superheater U deliver steam through a throttle valve D to a turbine T. The valve D is operatively connected through a member g with a member h controlling the fuel or air supply to the furnace F and with a member i controlling the regulator R in the feed-water pipe S, and the secondary or fine regulation is effected by the pressure and/or temperature of steam in the steam pipe (either behind the superheater, as shown, or between the superheater and the generator) exercising a control through connections o, n on one or other of the furnace factors. According to the Specification as open to inspection under Sect. 91 (3) (a) the member g instead of being connected with the valve D may be under the control of a venturi meter or a wattmeter, ammeter, &c. adapted for measuring or indicating the output delivered. This subjectmatter does not appear in the Specification as accepted.

Abstract: 1411521 Digital data transmission; code changing INTERNATIONAL BUSINESS MACHINES CORP 19 July 1973 [18 Aug 1972] 34535/73 Heading H4P In a system for encoding a binary signal stream divided into a number of blocks, signals are generated which are representative of the relative positions of elements in the two blocks, and code words are derived corresponding to the generated signals. The blocks may correspond to scanned lines of a document. As described, two consecutive line i-1, i of a scanned document are assumed to result in the signal blocks shown in Fig. 5. Output signals I, are derived for each "1" bit in the second of the two blocks by computing quantities IA = jl1 - jk - 1, IB= N-je1, I1=/jk+1 -je<1>/, I2 = lower of IA and IB where je<1> is the bit position of a "1" in block i-1 jk is the bit position of the previous "1" in block i jk+1 is the bit position of the present "1" in block i N is the number of bits in a block The values of output signals I are then computed in accordance with one of the following relationships The computed values of I are then fed to a code word generator in which corresponding code words are stored in a "look-up" system. A suitable code consists of b "1's" followed by a "0", followed by the last b bits of the binary representation of I where 2<b>#I<2<B+1>. At the receiver, the quantity jk+1. may then be computed for a particular code word from the corresponding signal I and the previously computed values jk, je<1>.

Title: Improvements in or relating to Gas Valve Assemblies
IPC: F23N5/26
Filed: 1968-07-22
Abstract: 1,195,490. Burner controls. HONEYWELL Inc. 22 July, 1968 [27 July, 1967], No. 34785/68. Heading F4T. In a gas valve assembly incorporating a gas valve similar to that described in Specification 1,125,119, in which a safety valve closure member 44, 43 is releasably coupled to a core 38 of a solenoid 10 by a catch 41, the solenoid being energized by an external flame sensitive device, e.g. a thermocouple, to maintain the valve open after initial depression of a button 3 and rod 31, and in which a release rod 45 may be depressed to release catch 41 and so effect closure of valve 9 despite operation of the solenoid 10, an annular knob 2 about button 3 is rotatable to adjust a gas flow control valve 6 and can be depressed, together with button 3, to depress the release rod 45. At its outer end, knob 2 has a flange 34 engaging with a shoulder 33 of button 3, and at its inner end the knob has a flange with two diametrically opposed cam portions 16, lying on different radii to allow rotation of almost 360 degrees and engageable with corresponding cam portions 17 on a portion 14 of a housing, so that rotation of the knob causes both it and the button 3 to be axially displaced. A shoulder 15 on the knob 2 is also engageable with the housing portion 14. Thus when rotation of knob 2 is such as to make the valve 6 approach its closed position, the closure member 35 of a main valve 8 on the rod 31 also tends to shut, and eventually both valves 8 and 6 are closed. The safety valve 9 is now closed either by directly depressing knob 2 or by arranging the camming action to depress knob 2 so far that valve 9 is closed automatically on extreme rotation of the knob. The knob 2 has four recesses 21 in which claws 20 of a drive element 22 engage to form a claw clutch by which rotation is transmitted to a gear ring 24 fixed to an externally threaded bushing 25. The bushing can be screwed within a fixed thread 26 and supports one end of a bellows 27 of a liquid filled temperature sensor, the other end of the bellows being linked to the gas flow control valve 6 by alever 28, so that the setting of valve 6 depends both on the setting of knob 2 and the temperature at the sensor. The valve 6 is preferably of the type which has a continuously variable setting apart from a snap action between the closed and slightly open positions. A pressure regulator 11, e.g. as described in Specification 1,010,602 is provided. In a modification, the releasable catch 41 is replaced by the catch arrangement described in Specification 1,125,120.
