Patent GB-394771-A (GB)
Title: Improvements in and relating to power units
IPC: F01K7/02
Filed: 1932-03-19
Abstract: 394,771. Systems for transmitting mechanical power. WHITE, W. A. and WHITE'S MARINE ENGINEERING CO., Ltd., Prince Consort Road, Hebburn-on- Tyne. March 19, 1932, No. 8272. [Class 38 (iv).] In a power plant incorporating a reciprocating steam-engine and an exhaust turbine, the power from one or both of the two prime movers is transmitted by an electric generator which supplies current to a motor. In one arrangement the engine and the turbine each drive a generator which supplies current to a common motor which may be reversibly mounted directly on the third shaft, or geared thereto. Each engine may drive a separate motor in the above plant. Fig. 3 shows a modified plant in which the engine A is geared to the driven shaft 5, and the L.P. turbine C is connected to the same shaft by a generator D and motor E3 which transmits its power through gearing 12 .. 15. By means of a switchboard 6 current is supplied to leads 16 for driving auxiliaries. A H.P. turbine C<1> added to the plant is supplied with live steam from the boiler F and exhausts to a feed-water heater H. This turbine may be used to drive the auxiliaries with the main engine stopped. The reciprocator may be geared to the turbine and the gearing may be hydraulic instead of mechanical. For going astern the engine and turbine maintain the same directions of rotation, but a reversing switch alters the electrical drive. This may be effected automatically by coupling the switch to the reversing gear. The propeller may be driven independently of the reciprocator or of the turbine by arrangement of change-over valves. The reciprocator may be other than triple-expansion, and may operate with one or more cylinders in parallel. Specifications 378,235, 378,264, 383,782, and 392,254, [all in Group XXVI], are referred to.

Title: Improvements in or relating to a process of recovering products from compound silicate materials
IPC: C22B47/00
Filed: 1950-04-11
Abstract: Silicate materials containing Ca, Fe and Mn are mixed with oxygen-containing Ca or Si material to bring the composition of the material to a molar ratio (CaO-3 P2O5) /Si O2 of between 2.5 : 1 and 1.7 : 1.  The mixture is heated to a temperature to form a dicalcium silicate portion and an Mn and Fe oxide portion and the two portions are separated, e.g. magnetically after slow cooling.  The separated Mn-containing portion may then be treated, in the form of a slurry, with acid to purify it further.  The concentrate may then be mixed with lime, silica and carbon and smelted to produce spiegeleisen containing, e.g. Mn 34 per cent, C 6 per cent and the balance substantially all Fe.  Alternatively the concentrate may be mixed with silica and carbon and smelted to produce a metal containing Fe with only a small proportion of Mn, the resulting slag being mixed with lime and carbon and smelted to produce a metal product of high Mn content, e.g. Mn 91 per cent, C 4 per cent and the balance Fe.

Filed: 1966-03-03
Abstract: 1,114,102. Supply systems for consumption apparatus. SEVCON ENGINEERING Ltd. 31 Jan., 1967 [3 March, 1966], No. 9258/66. Heading H2H. [Also in Division G3] A circuit arrangement for producing from a direct voltage of one value a direct voltage of another, lower, voltage comprises means for chopping the original voltage into pulses which may have a variable frequency or a variable width. A direct voltage is applied at terminals X and a lower voltage is taken from terminals Y, the chopping function being effected by two controlled rectifiers SCR1, SCR2. Conduction of SCR1 causes capacitor C1 to charge by way of inductor L, a further capacitor C2 being charged at the same time. When the capacitor C2 is fully charged, SCR2 fires after a time delay determined by a delay unit TD, thus causing SCR1 to be extinguished. After a further period determined by a variable unit FB, SCR1 refires, extinguishing SCR2 and the cycle is then repeated, the output direct voltage being the mean of the pulses which are produced. The arrangement produces pulses having a constant width and a variable frequency. In a further embodiment the units FB, TD are associated with SCR2 and SCR1 respectively and with this arrangement the pulses have constant frequency but variable width. The arrangement is suitable for producing a voltage for the headlights of a vehicle driven from a higher voltage supply.

Title: Scintillation camera
IPC: G01T1/164
Filed: 1974-03-01
Abstract: 1460524 Scintillation camera OPTISCHE INDUSTRIE DE OUDE DELFT NV 1 March 1974 [9 March 1973] 9263/74 Heading H4F In a scintillation camera of the type using one or more image intensifiers 9, 11, 13 to brighten the image on the anode screen 7 of the scintillation tube, said image intensifiers cause pincushion distortion of the position of an image point on the display screen 14a of the last intensifier with respect to the true position of the scintillation giving rise to the image point on the scintillation surface 2, 3. Such pin-cushion distortion has previously been counteracted to some extent by the barrel distortion in the final position co-ordinates of said image point as determined by the standard system of four photomultipliers viewing the intensifier display screen 14a. This method is improved by the use of a reflecting cone 19 interposed between the display screen 14a and the four photomultipliers 15, 16, (17), (18) which are now cruciform arranged in a plane at right angles to the axis of the intensifiers, the cone being so positioned and constructed that the signal produced by any one of the photomultipliers, as a result of a spot on the display screen 14a of constant intensity, varies according to a desired law as the spot moves from the centre of the screen, e.g. decreases to counteract pin cushion distortion, or increases to overcome barrel distortion. To obviate the use of a separate collimator, the scintillation surface is formed of a matrix of through areas 2 of scintillating material surrounded by lead 1. The scintillation surface is backed by a photocathode 4. The several image intensifiers are optically coupled by fibre optics 8, 10, 12. The cone may be hollow, having its apex away from the screen 14a and using its reflective interior surface to transfer light from the screen to the photomultipliers.

Abstract: 1,102,321. Levitating and stabilizing apparatus. NATIONAL RESEARCH DEVELOPMENT CORPORATION. 5 March, 1965 [5 March, 1964], No. 9345/64. Heading H2A. Two A.C. energized magnetic structures 1, 2 are spaced one above and one below a sheet of conductive material 13 whose position is to be controlled so that the electromagnetic forces produced at poles 3, 5 and 4, 6 interact to move the sheet into a stable position. Shading rings 7-10 are used to form a progressive flux phaseshift across the pole face in the air-gap, thereby producing a force pattern which reverses at Y halfway across the pole faces 4, 6, Fig. 2 (not shown). The position of this reversal is determined by the size of shading rings used and the edge of any width sheet is maintained in this position. The number of shading rings used depends on the conductivity of the plate to be guided or secondary windings supplied with phase displaced current may be used. Alternatively, a non-uniform or tapered air-gap may be used.
