Title: Improvements in and relating to governing devices for elastic-fluid prime movers
IPC: F01D17/04
Filed: 1935-03-23
Abstract: 448,911. Fluid-pressure servomotorcontrol systems. PARSONS & CO., C. A., and HORSLEY, W. D., Heaton Works, Newcastle-on-Tyne. March 23, 1935, No. 9149. Drawings to Specification. [Class 135] A governing device for elastic-fluid prime movers, particularly those driving synchronous alternators and of the kind controlled by a speed governor and by a supplementary governor device which comes into action in response to a sudden loss of load to initiate the closing of the steam valve before the speed can rise to such an extent as to operate the overspeed emergency apparatus, has the supplementary control exercised by a differential relay connected to the rotor excitation circuit in such a manner that the current in one of the two relay coils is proportional to the rotor current while that in the other is proportional to the rotor voltage. The relay is preferably set to be inoperative when the alternator is carrying its full load. If the load falls gradually excitation current and voltage are reduced in proportion and relay remains inoperative. As temperature and resistance of the rotor is lower at light loads the relay is biassed in the inoperative direction. A sudden drop of load however causes the current to rise and the voltage to fall so operating the relay. This closes a circuit containing of solenoid forming part of the governor control described in Specification 448,874. Specification 444,271 also is referred to.

Title: Improvements relating to the manufacture of copper oxide rectifiers
Inventor: SHEPPARD EDWARD ALFRED
IPC: H01L21/16
Filed: 1961-03-14
Abstract: 955,727. Semi-conductor devices. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. March 13, 1962 [March 14, 1961], No. 9233/61. Heading H1K. In a method of manufacturing a copper oxide rectifier element in which a copper plate is raised to a first elevated temperature in an oxidising atmosphere to produce a layer of cuprous oxide thereon, annealed at an elevated temperature lower than said first temperature and quenched, a delay is introduced between annealing and quenching during which the plate is held in cool air, and the delay is so chosen as to endow the rectifier element with a predetermined reverse breakdown voltage characteristic. The delay period is one to two minutes. The first elevated temperature is provided by a furnace at a temperature of. 1040‹ C. Air is slowly fed to the furnace. The annealing temperature is 550‹ C. and during the annealing process a layer of black copper oxide is formed on the plates. The element is maintained both in the furnace and in the annealing chamber for about ten minutes. After quenching in cold water one side of the element is exposed to dilute nitric acid to remove all oxide and the black oxide produced during annealing is removed from the other side by further acid treatment, to leave a cuprous oxide layer on said other side. A contact is formed on the copper oxide layer by vacuum deposition of gold using a mask. Subsequently the rectifier element is aged in a chamber maintained at 60 ‹ to 100 ‹ C. for a period of from a few hours to a number of days. The ageing may be performed after rectifier elements have been assembled into stacks to form a complete assembly. The copper plates may be discs or washers and may contain a small amount of antimony.

Title: Improvements in and relating to the production of dyeings on the fibre
IPC: C09B45/06
Filed: 1927-04-06
Abstract: 293,813. Carpmael, W., (I. G. Farbenindustrie Akt.-Ges.). April 6, 1927. Azo dyes.-Dyeings on cotton are obtained by impregnating the fibre with a urea derivative of an azo or disazo dye containing a carboxyl group or groups (other than a salicylic acid grouping) and containing a free amino group in the coupling component, and after-treating the fibre with a chromium salt. The said urea derivatives are obtained by the action of phosgene in the paminoazo or .p-aminodisazo compounds. The process is of particular importance in batik dyeing. In examples, (1) cotton is dyed with the urea derivative of the dye from 1-amino-3-sulpho-6- chlor-5-benzoic acid and 3-amino-4-cresolmethylether, dried, and treated with chromium sulphate solution; a clear golden yellow is obtained, (2) a clear greenish-yellow is obtained by dyeing cotton with the urea derivative of the dye obtained by coupling diazotized 1 : 3 : 5-aminosulphobenzoic acid with o-anisidine and after-treating with chromium chloride solution, (3) a batik material with wax resists is treated as in example 2 and subjected to boiling water to remove the wax; the reserved portions remain white while the unreserved portions are dyed yellow; when employing materials without reserve, but previously dyed blue, for example with indigo, they pass to green, and (4) dark reddish-orange shades are obtained by dyeing with the urea derivative of the dye obtained by diazotizing aminoazobenzenedisulphonic acid and coupling with 2-amino-4- methyl-phenylglycollic acid, and after-treating with chromium chloride solution; the urea derivative of the dye obtained by diazotizing 2 : 5-dichloraniline-4-sulphonic acid and coupling with m-aminobenzoic acid gives a yellow shade, and the urea of the dye from naphthionic acid and' 2-amino-4-methyl-phenylglycollic acid an orange shade. Specification 215,769 is referred to. 1 : 3 : : 5-Aminosulphobenzoic acid is obtained by sulphonating benzoic acid and then nitrating and reducing.

Title: Mechanical translator for printing telegraph systems
IPC: H04L17/18
Filed: 1929-03-25
Abstract: 309,129. Siemens & Halske Akt.- Ges. April 5, 1928, [Convention date]. Type-printing telegraphs.-In a selective device for printing-telegraphs and the like having an electromagnet 2 energized by the signal impulses, armatures I - - V, corresponding in number to the number of combination elements, co-operate with the electromagnet and are controlled in turn. A shaft 9 is released by a preliminary impulse and rotates counterclockwise with the result that a stop 13, previously held by a cam 18, is released and drawn back by a spring so that selector levers 5 are free. A cam 8 then bears on a nose-piece 7 and forces the selector lever down so that the tip of the armature I is forced out of an inclined indentation on the selector lever. The selector lever jumps back behind the cam at a moment coresponding to the middle of the first signal impulse and releases the armature. If the magnet is not energized the armature falls off and holds the selector lever, but if the magnet is energized it holds the armature and the selector lever is drawn by a spring 10 to a stop 11. The movement of the selector lever is transmitted by a spring blade 14 to a bar 15. The bars corresponding to the other signal element are adjusted in a similar way and, at the end of the rotation of the shaft, the cam 18 raises the lock 13 and a projection 12 passes over or under extensions 20 according to the position of the corresponding selector lever and locks the combination. The shaft is driven through friction coupling and, at the end of its rotation, a lever 22 is pressed down by an inclined projecting surface 27 on an arm 24 fastened to the shaft so that the lever 22 comes into contact with a stop 21 to stop the shaft revolving and the armatures are pressed against the magnet by projections 26 on a pawl 23. To release the shaft a current interruption precedes the signal combination and causes the magnet to allow the armatures to drop and throw the pawl 23 back, thus separating the arm 22 from the stop 21.

Abstract: 1,102,924. Fluid-pressure servomotor systems. STOTHERT & PITT Ltd. March 4, 1966 [March 8, 1965], No.9713/65. Heading G3P. [Also in Division F1] In a pumping system having a positive displacement or roto-dynamic pump 1, partial closure of a shut-off valve 16 results in higher than normal working pressure in a discharge chamber B, and a discharge line 12 of a parallel-connected auxiliary pump 2. The increased pressure raises a pilot valve 7' against the manually adjustable loading of a spring 8 and thereby communicates the pressure in line 12 to the underside of a piston 5 via passages 18, 11. Pressure balance is thus effected across piston 5 enabling the pressure in chamber B to open relief valve 4 in return line 19. The same result occurs on complete or almost complete closure of the valve 16, and the consequent pressure differential between chambers B and C causes the non-return valve 15 to close and the valve 4 to open further and when completely open to permit the pressure in chamber B to fall to a value just sufficient to effect the return flow through the relief valve. At the maximum raised position of the piston 5, pressure in line 12 is relieved through a passage 20. Re-opening of the valve 16 reduces the pressure in line 12 and thereby allows the pilot valve 7' to return to the position shown wherein the underside of the piston 5 is communicated to the inlet sides of the pumps via passages 11, 10. Thus valve 4 closes and the system resumes normal working.

Abstract: 543,052. Frequency measurements. ELECTRICAL RESEARCH PRODUCTS, Inc. June 5, 1940, No. 9812. Convention date, July 26, 1939. [Class 37] A frequency indicator for ultrashort electro-magnetic waves comprises a tuned circuit including a closed cylindrical metallic vessel and a tuning rod projecting into it, means extending into the vessel for loosely coupling a source of electro-magnetic wave energy to the rod and a diode detector for rectifying energy obtained from the tuned circuit, and mounted within the vessel. The source of energy of which the frequency is to be measured is connected to a concentric pair of conductors 18, 22. The inner conductor 22 has at its end an electro-static coupling member 24 providing a loose coupling to a tuned circuit comprising a closed cylindrical vessel 20 having a highly conductive internal surface and a rod 28 with a highly conducting external surface supported concentrically within the cylinder 20 and extending through its lower end. The lower end of the rod 28 is provided with a micrometer head 30 by means of which the length of the rod within the cylinder 28 may be measurably adjusted. A slotted spring contact member 26 surrounds the rod 28, its upper end making contact with the rod at about one-tenth of the length within the cylinder 20 from the lower end, the lower end of the member 26 being connected to the cylinder 20. Mounting brackets 21 are welded or otherwise attached to the vessel 20. An additional bracket 23 supports the concentric line 18, 22. A detector, enclosed within the vessel 20 comprises a diode 32 having its plate lead 34 connected to the upper end of the member 26. The cathode and heater leads to the diode 32 are connected to terminals 53 which have sufficient capacitative coupling to the lower end of the vessel 20 to prevent ultra-short wave energy from leaving the vessel 20 along these leads. The rectified current from the diode 32 is led out from the vessel 20 and passed through a resistance load and a micro-ammeter, the current through which is a maximum when the tuned circuit is adjusted to the frequency of the wave energy supplied to it. The reading of the micrometer head 30 is then a measure of the frequency. Specification 543,051 is referred to.
