Title: Improvements in and relating to apparatus for raising and forcing liquids by steam or gas pressure
IPC: F22D5/24
Filed: 1949-08-15
Abstract: 669,870. Automatic liquid-level control systems. CHAPMAN, HAYWOOD & CO., Ltd., and PICCARDO, C. Aug. 15, 1950. [Aug. 15, 1949], No. 21171/49. Class 38 (iv). [Also in Groups XIII and XXVIII] In apparatus for raising or forcing liquids from one or more closed vessels by direct air, gas or steam pressure under the control of valves operated according to the liquid level in the vessel or vessels, the control valves are operated by electrical means energized through circuits which are closed by liquid level responsive devices at minimum and maximum liquid level in the vessel or vessels, the minimum level circuit including a resistance which is short-circuited by the maximum level circuit whereby the electrical means can only be actuated when the vessel is full and can only be released when the vessel is empty. Water is delivered by gravity from a feed water tank 3 of a boiler plant to a lifting vessel 2 and is raised therefrom by steam pressure, through a valve 7 and pipe 6 to a feeding vessel 1. The water is delivered from the latter by steam pressure and gravity, through a pipe 8 and valve 9 to the boiler. The supply and exhaust of steam through a pipe 19 leading to the vessel 1 is controlled by a control valve 17, and through a pipe 14 leading to the vessel 2 by a control valve 10, 11. The control valves, which place the vessels alternately in communication with a steam pipe 15 and an exhaust pipe 20 leading to the tank 3, are actuated by diaphragms 21. The upper surfaces of the diaphragms are permanently subjected to steam pressure through liquid columns 23 and their lower surfaces communicate through liquid columns in pipes 24 with a chamber 25 which is permanently open to steam pressure through a pipe 26 and which may be exhausted to atmosphere, through a pipe 27 controlled by a pilot valve 28 so as to effect a downward movement of the diaphragms and consequent actuation of the control valves. The pilot valve is raised by a solenoid 30, energized through a transformer 35 and rectifier 36, and controlled by upper and lower float switches 31, in the vessel 2, and a relay 38 energized through a rectifier 37, and controlled by upper and lower float switches 31 in the vessel 1, so that the vessels are alternately filled and emptied. The circuit of the lower float switch in each vessel includes a resistance 41, 45 which is short-circuited by the circuit of the upper float switch when the latter is closed. In another embodiment a single vessel is used and controlled in a similar manner to the vessel 2. In other embodiments the control valves are three or four-way semi-rotary valves actuated by diaphragms or pistons and controlled by solenoid operated pilot valves.

Abstract: 166,049. Pease, E. L. April 14, 1919. Closure members. -Apparatus for the subdivision and treatment of fluids of various' kinds, including streams of finely-divided or comminuted matter such as coal or other dust mixed with air, gas, or other fluid carrier, comprises a number of plates or sheets of uniform thickness throughout and having entirely flat or plane surfaces arranged closely together so that they make contact with each other at certain parts and so shaped as to external outline that when assembled they provide narrow spaces in communication with one another by way of one or more passages extending transverse through the set of plates and formed by the juxtaposed edges of the plates. In an arrangement suitable for mixing fluids &c., flat plates A, B, Fig. 1, bear against each other for part of their surface area, and are so shaped and arranged that flat shallow spaces are formed between the plates of each set and a passage j between adjacent edge portions of the sheets common to all the flat narrow spaces. Two sets of sheets may be fitted within a casing having separate inlets for fluids, one fluid passing through the shallow spaces between one set of plates, and the other fluid through the spaces between the other set, and the two sets of streams intermingling in the common passage j. Fig. 4 shows an arrangement suitable for use as a gas and air mixing valve or burner, the plates A, B being clamped together by bolts k within a cylindrical casing provided with inlets n, o. The plates may be mounted in the casing so that they can be rotated to close the inlets. The mixture of air and gas passes out through the central spaces p between the adjacent edges of the sheets. The two sets of sheets may be of different thicknesses so that the spaces between the sheets of one set may be larger than these between the sheets of the other set.

Abstract: 517,290. Indicating. ENGLISH ELECTRIC CO., Ltd., ROGERS, A. E., and BEGENT, H. H. July 18, 1938, No. 21314. [Class 78 (v)] An indicating device for winding gears for mines and like machines comprises two pointers 1b, 2b moving over the same scale 7. The pointer 1b is connected by a stem 1a to an electromagnetic device 1 which indicates the actual speed of the winding gear. The device 1 may comprise a voltmeter or frequency meter connected across the terminals of a tachometer generator 3 driven by the winding gear 4. The pointer 2b is connected by a stem 2a to an electromagnetic device 2 which responds to the position of the cage in the shaft and may comprise a voltmeter connected across a potentiometer resistance 5 through a brush 5a which is swung over the resistance by a cam 6 driven by the winding gear. The pointers lb, 2b overlap when the cage is moving at the right speed for its position, and the pointers may be coloured differently to facilitate inspection. In a modification the pointers, move co-axially over a flat dial, the devices 1, 2 being disposed horizontally in line. In this form the pointer 1b may consist of the edge of a black sector so that the pointer 2b is hidden if actual speed is below what it ought to be. Movement of pointer 1b considerably in advance of pointer 2b may close contacts to. operate a visible or audible signal or to trip a relay for applying a brake. Alternatively, each of the movable devices 1, 2 may drive one element of a differential gear, the third element of which moves only on any difference between the angular positions of the pointers, and can actuate a switch.

Patent GB-597542-A (GB)
Title: Process for the preparation of new monoazodyestuffs
IPC: C09B45/16
Filed: 1945-08-22
Abstract: Monoazo dyestuffs are manufactured by diazotizing o-aminophenolsulphonic acids or their nuclear substitution products (but excluding 4 - chloro - 2 - aminophenol - 6 - sulphonic acid), and coupling with alkyl esters of 7-hydroxy - 1 - naphthylcarbamic acid, and, if desired, converting the products into their chromium complex compounds.  The latter dye wool from acid baths in grey, grey-blue, blue and olive shades, whilst similar shades, though somewhat less bright, are obtained by applying the chromium-free dyestuffs and chroming on the fibre, e.g. by the after-chroming or the single bath chroming process. In an example, 3 : 4 : 6 - trichloro - 2 - aminophenol - 5 - sulphonic acid is diazotized and coupled with the ethyl ester of 7-hydroxy-1-naphthylcarbamic acid, and the product is refluxed with a solution of chrome alum and formic acid.  A table gives the properties of further dyestuffs obtained from the same coupling component and diazotized 4-chloro- and 4-methyl-2-aminophenol-5-sulphonic acids, 2-aminophenol-4 : 6-disulphonic acid, 2-aminophenol-4-sulphonic acid and its 6-nitro- and 6-benzoylaminoderivatives, 4-nitro- and 4-benzoylamino-2-aminophenol-6-sulphonic acids, 2-aminophenol4-carbamic acid ethyl ester-6-sulphonic acid and 2-aminophenol-6-carbamic acid ethyl ester-4 - sulphonic acid. Additional components specified are: 6-chloro-2-aminophenol-4-sulphonic acid; and the methyl and n-butyl esters of 7-hydroxy-1-naphthylcarbamic acid. Specification 275,258, [Class 2 (iii)], is referred to.  Alkyl esters of 7-hydroxy-1-naphthylcarbamic acid are obtained by the action of esters of chloroformic acid on 1 : 7-aminonaphthol suspended in water or in an inert organic liquid in the presence of a neutralizing agent, e.g. sodium carbonate or chalk.  The Specification as open to inspection under Sect. 91 comprises also the use, as diazo component, of 4-chloro-2-aminophenol-6-sulphonic acid, and contains a further example in which this compound is diazotized and coupled with the methyl ester of 7-hydroxy-1-naphthylcarbamic acid, and the product is refluxed with a solution of chromic alum and sulphuric acid. Reference is also made to the use of the b -chlorethyl ester of 7 - hydroxy - 1 - naphthyl - carbamic acid as coupling component, and to the dyestuffs 4 - chloro - 2 - aminophenol - 6 - sulphonic acid --> 7-hydroxy-1-naphthylcarbamic acid ethyl, n-butyl and b -chlorethyl esters.  This subject-matter does not appear in the Specification as accepted.

Title: Transistor latch circuit
IPC: H03K3/356
Filed: 1974-05-15
Abstract: 1466195 Transistor bi-stable circuit INTERNATIONAL BUSINESS MACHINES CORP 15 May 1974 [29 June 1973] 21511/74 Heading H3T Set signals are applied to a field effect bi-stable 4, 5, 6, 7 at node A via a field effect transistor 1, output signals are taken from node A via a second field effect transistor 3 and reset signals are applied to the same node A via a reset field effect transistor 2. When a low level input is applied to IN and a positive potential applied to R, transistor I is turned off and transistor 2 is turned on to set bi-stable 4, 5 in the state with transistor 4 off and transistor 5 on and also to turn transistor 3 off giving a high level output. Transistor 8 may be turned off at the time at which an input is applied, and if so it is turned on by transistors 4, 5 taking up the above stated conditions. If a high level input is applied transistors 1, 3, 4 are turned on and transistor 5 is turned off giving the opposite output condition. With the bi-stable in this state, transistor 8 completes the latching loop. Turning transistor 8 off at the time of application of an input provides a high impedance to reduce power consumption if a high level input is applied when transistor 5 is on. Alternatively transistor 8 may be biased to have a relatively high impedance, e.g. about ten times that of transistor 1.
