Title: Improvements in the starting and manoeuvring of gas turbine plants for electric ship propulsion and the like
IPC: F02C9/18
Filed: 1945-10-22
Abstract: 607,884. Gas turbines. BRITISH THOMSON-HOUSTON CO., Ltd., and FORSLING, B. E. G. Oct. 22, 1945, No. 27750. [Class 110 (iii)) In a gas turbine including high- and lowpressure turbines on separate shafts, the highpressure turbine driving an air-compressor and the low-pressure turbine providing useful power and in which the output of the useful power turbine is controlled by a valve in a byepass conduit, no control devices are inserted in the flow path of the useful power turbine. The turbine rotor 13 drives an alternator 14 for electric ship propulsion. The turbine rotor 10 drives the air compressor 2 and, through gearing 11, the exciter 12 for the alternator. The compressed air is heated in an economizer 6 and passes to two combustion chambers 8 formed in the lower head of the economizer. For starting, the exciter is used as a motor, air is blown off from an intermediate point in the compressor through a valve 17 and the useful power turbine 13 is byepassed by the open valve 16. When manoeuvring, the load taken by turbine 13 is controlled by the byepass valve 16. In a plant with three turbine rotors on independent shafts, the high-pressure turbine drives the high-pressure compressor and the exciter, the intermediate or low-pressure turbine 'drives a low-pressure compressor and the remaining turbine drives the alternator. The gases are re-heated in a combustion chamber between the high and intermediate turbines. For starting, the low-pressure compressor and the useful power turbine are byepassed. In another plant, two low-pressure turbines in parallel receive re-heated gases from the same high-pressure turbine which drives the highpressure compressor and the exciter. One of the low-pressure turbines drives the lowpressure compressor and the other the alternator.

Patent GB-754909-A (GB)
Title: Improvements relating to automatic selecting systems
Inventor: FLOOD JOHN EDWARD
IPC: H04Q3/00
Filed: 1953-10-09
Abstract: 754,909. Automatic exchange equipment. SIEMENS BROS. & CO., Ltd. Oct. 1, 1954 [Oct. 9, 1953], No. 27867/53. Class 40 (4). A matrix of test terminals TT available for random selection are connected in rows and columns over rectifiers MR1-MR3 and resistors R1-R4 to two groups of coldcathode gas - discharge tubes VT0-VT4 and VU0-VU4 (or other negative-resistance devices such as thermionic valves, thermistors or transistors with positive feedback), a free test terminal being taken into use by the random firing in a row group of a gas tube associated with one or more free terminals, followed by like response of a single tube in the column group. The test terminals may also be arranged in a cubic matrix and associated with three groups of tubes. As shown in Fig. 1, each group of tubes is connected to a start terminal GM over a common impedance R7, R8 which permits random firing of one gas tube only in a group. Busy test terminals are marked by a low potential, and only if one or more test terminals in a row are available does a higher free potential permit initial ionisation of the associated tube VT0- VT4. When a free outlet is required the potential of terminal GM is raised, causing one of the ionised row tubes to fire and increase its cathode potential over resistor R5. As a result the potential drop across resistors R4 associated with free terminals is reduced, and an increased potential becomes effective over rectifiers MR3 to cause firing of a column tube associated with a free terminal in the row. Busy terminals are excluded since their rectifiers MR2 are biased back initially by the potential of free outlets present at the cathodes. Marking terminals T0-T4 and U0-U4 identify the fired row and column tubes respectively by indicating the increased potential across cathode resistors R5, R6, these potentials being combined, Fig. 2, over pairs of resistors to indicate the selected test terminal in a co-ordinate array of marking terminals TU. When a connection has been made with the selected test terminal, the potential at GM is reduced to extinguish the tubes. The test terminals may also be arranged in a cubic matrix, Fig. 3, in which case groups of row, column, and depth tubes VH, VT, VU are necessary, one tube of each group being shown. The arrangement of rectifiers and resistors at the intersections of rows and columns is repeated for the intersecting columns and depths so that sequential firing of a single tube in each tube group VH, VT and VU takes place in that order. According to the Provisional Specification, the anode potentials of the tubes may be derived from an impedance in the anode circuit of a thermionic valve which is rendered non- conducting when a test terminal is marked. The use of a double triode is suggested.

Title: Automatic measuring apparatus for granular substances in bulk
IPC: G01F3/28
Filed: 1933-10-13
Abstract: 426,214. Meters for granular materials. LETREUX, A., 4, Avenue Viviani, Constantine, Algeria, France. Oct. 13, 1933, No. 28292. [Class 69 (i)] In meters of the intermittently-rotatable drum type for granular materials, the rotation of the drum and the position of a feed hopper closure are controlled by a rocking member in the hopper. When the parts are positioned as shown in Fig. 1, the closure 9 carried by the arms 18 of a spider is withdrawn so that grain &c. can pass from the feed hopper 7 to the drum compartment C<1>; and the drum is held stationary by the engagement of abutments 32 with shoulders 22<1> in cam paths formed in levers 22. When the compartment is filled, grain accumulating in the hopper 7 forces the rocker 12 into the position shown in Fig. 2. A spring-influenced latch 16 is thereby moved to free the closure 9, and the levers 22 drop and turn the spider clockwise by connections at 201 with arms 20. The hopper is thus closed, and the abutment 32 freed, so that the drum can turn in the direction of the arrow f. The next abutments 33 on the drum enter the cam paths in the levers 22, and restore the parts to the position shown in Fig. 1, but with the compartment C<2> under the hopper. The compartments discharge into a trough 28 containing a pivotally-mounted board having connections at 261 with spider arms 24, movement of the spider being thus prevented if the trough is full. Adjustable weights 30 on spider arms 29, a manuallyoperated closure 8, and locking-members 35 actuated by gravity and the abutments 32, 33 are provided.

Title: Improvements in or relating to the application of chemically-bonded coatings to the surface of aluminium
IPC: C23C22/86
Filed: 1959-08-21
Abstract: The coating of aluminium using an aqueous solution containing from 0,15-12,5 grams per litre of fluoride iron, from 2-60 grams per litre of hexavalent chromium (expressed as CrO3) and from 2-285 grams per litre of phosphate (expressed as PO4), and having a pH of 0,8-4,5, is controlled so as to ensure production of powder free coatings over a prolonged period by contacting the solution intermittently or continuously with a cation exchange resin to which there is also added both potassium and sodium in amounts such that aluminium dissolved in the solution in excess of 1 gram per litre is precipitated.  Sodium and potassium fluorides are added in a molar ratio of as near 2 as possible, intermittently, whenever the concentration of dissolved aluminium approaches or exceeds 1 gram per litre, in the minimum amount necessary to precipitate the aluminium. The contact with ion exchange resin may be maintained by continuously withdrawing a portion of the solution, passing it over the resin and returning it.

Title: Improvements in or relating to pressure indicators and recorders
Inventor: MANSFIELD WILFRED PERCIVAL
IPC: G01L9/12
Filed: 1949-12-14
Abstract: 692,588. Pressure gauges. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Dec. 8, 1950 [Dec. 14, 1949], No. 29115/50. Divided out 692,561. Class 106 (ii). A fluid pressure pick-up having a plate, e.g. a disc or diaphragm, which is subjected on opposite sides respectively to a fluid pressure whose variations are to be indicated or recorded and a known fluid pressure which may be varied over a required range, produces an electric signal at the instant of pressure reversal across the disc or diaphragm, and successive signals are applied to the control grids of two gasdischarge thermionic tubes, operating indicating or recording means, so as to render the tubes alternately conducting. The pick-up may be of the electrical contactor or electromagnetic type, or, for the circuit shown, of the variable capacitor type, e.g. as described in Specification 692,561. The pick-up capacitor is connected across the input terminals of a circuit 8, the output of which is fed through a two-stage amplifier 7 and a phase-inverter 3 to the pushpull thyratron circuit 4. The phase inverter may comprise a valve having load resistors in its anode and cathode circuits or a transformer 12, as shown, having the terminals of its secondary winding connected to the grids of normally non-conducting thyratrons 13, 14. Whenever a signal arrives from the pick-up one of the thyratrons discharges through a capacitor 18 in its anode circuit thus supplying a pulse to the primary of an output transformer 17 so that a spark is produced across its secondary which is recorded on a sheet of paper on a drum recorder (not shown). Various modified circuit arrangements are described. For example, where the pressure recorder is used for testing an apparatus such as an I.C. engine, the piston may close electric contacts when in top deadcentre position in the engine cylinder so that this position may be indicated on the record.
