Title: Improvements in and relating to valve gear for locomotives and like self-propelled vehicles
IPC: F01L29/04
Filed: 1930-11-28
Abstract: 367,062. Engine e valvegear. MOUCHLY, J., Mount Carmel, Haifa, Palestine. Nov. 28, 1930, No. 35831. [Class 122 (ii).] In locomotive and like gears having cam-operated lift valves, the cam shaft is rotated by helical gearing receiving its motion from a non-rotatable rod eccentrically driven from a wheel axle. A fly crank a, as shown in the Figure, mounted upon a driving crank is connected to a rod b centrally supported by an oscillating lever d the other end of which is connected to a crank pin c driving a weighted lever g on a rotary shaft driving the cam. The crank pin c rotates in a circle and has a pin-and-slot connection with the lever d. Alternately the crank a may be mounted on the driving pin of the leading wheels coupled to the driving wheels. The construction eliminates the effect of motion emanating:from the track. In a four-cylinder engine with steam chests in the same horizontal plane, a double, driving, weighted lever g with a common sliding block is used. If the inside steam chests are not in the same plane as the outside chests, the rod b is provided with a small projecting arm to assist in the drive. The rod b may be rigidly attached to the end of a coupling-rod. The rod d is then dispensed with. Specifications 309,620 and 331,600, [both in Class 122 (ii), Steam-engine distributing and expansion valves &c.], are referred to.

Title: Continuous process for converting saponifiable fats into soap and glycerin
IPC: C11D13/04
Filed: 1936-12-31
Abstract: <PICT:0482535/III/1> Fatty acids obtained by the splitting of fats with water under pressure as described in Specification 466,596, are converted into soap by treating the fatty acids produced, under pressure and without reduction of temperature, with an alkaline reagent and sufficient water to produce a neat soap, which is then sprayed. Streams of fat and water at a temperature of 365 to 600 DEG F., pass in counterflow in a column 13 under sufficient pressure to maintain the water liquid.  A catalyst such as the oxides or soaps of zinc, calcium or magnesium is added.  Glycerine water is drawn off into a chamber 19.  The fatty acids produced, which include about 11 per cent of water, pass from the top of the column through a pipe 23 at about 470 DEG  F. to a mixer 30 under pressure, to which caustic alkali or soda ash is admitted in controlled proportions from a tank 27.  The saponifying agent may contain fillers such as sodium silicate, borax, or trisodium phosphate.  The hot soap mixture containing about 30 per cent of water is sprayed through a nozzle 32 into a chamber 33, where the pressure drops to atmospheric pressure, whereby the water is evaporated.  Cooling air is admitted through pipes 34.  Moisture content of the soap powder produced is controlled by adjusting the temperature of the liquid soap, and the temperature and volume of the cooling air.  The soap powder is of good colour due to avoiding contact with air of the fatty acids or of the soap until the latter is at air temperature.  The soap particles are of solid irregular shaped form, readily soluble in water, and may be rolled or plodded to form bars or flakes.  U.S.A. Specification 1,652,900 is referred to.

A once through vapour generator comprises a tube lined furnace chamber 8, fired by corner mounted burners 28. Combustion gases leave the furnace to pass over convection heated superheater, reheater and economizer heating surfaces 18 and 15, 25 and 3 respectively. A portion of the gases are recycled by fan 30 through ducts 29, 32 under the action of controller 49 to maintain the reheat steam temperature, measured by temperature sensor 47, constant. The tubes 7 lining the furnace 8 have their adjacent fins 6 welded together, and are divided into a number of peripheral parallel flow sections 9. The temperature of the fluid leaving each of these sections is measured by sensors 13, and the values compared with the average value of all the sections obtained in controller 38. The resultant signals are used to set proportioning dampers 34, to regulate the recirculated gas flow through individual gas recirculation plenums 33, spaced around the periphery of the furnace 8 (and see Fig. 2, not shown), each of which are associated with one of the parallel flow sections 9. In this way the fluid outlet temperatures from each of the sections 9 are maintained the same.

Title: Method for detecting suspended solid material in liquids
IPC: G01N21/53
Filed: 1959-10-26
Abstract: 889,405. Photo-electric examination of liquids. BRITISH PETROLEUM CO. Ltd., EVANS, N., WICKS, K., and SMITH, G. J. bct. 11, 1960 [Oct. 26, 1959], No. 36195/59. Class. 40(3). In an arrangement to detect minor amounts of solid material suspended in a liquid which may also have suspended in it a minor amount of another liquid whose solubility increases with increasing temperature, the sample of the liquid to be tested is heated to dissolve the suspended liquid in the other liquid, and the heated liquid is split into two streams, from one of which the solid material is removed, and the light absorption of the respective streams is compared by passing a beam of light through each stream. The arrangement is, in part, similar to that described in Specification 886,758. The sample withdrawn through line 1 from a main supply 2 is passed through a heater 4 and an air/vapour separator 3, part of the heated stream passing over a line 5 and a filter 7 to an enclosure 8 and an outlet 9 to a waste line, whilst the remainder of the stream passes through a dummy enclosure 10 to an enclosure 11 and an outlet 12 to the waste line. Light beams are passed from a source 15 through the liquid in enclosures 8, 11 to associated photo-cells 13, 14 connected in adjacent arms of a balanced bridge circuit having a fixed resistor 16 and a variable resistor 17. A diagonal of the bridge includes an indicator 18 including an alarm which is operated if solid matter is detected. The air/vapour separator 3, Figs. 3, 4 (not shown) is formed by an enclosure with glass balls supported on a gauze platform mounted above the floor of the enclosure. Liquid from line 1 is also passed over a line 19, located in advance of the heater 4, and through connections 20, 21 to enclosures 22, 23 surrounding the photocells 13, 14 and thence by output lines 24, 25 to the waste line. The arrangement may include a disperser located prior to the heater to facilitate solution of the suspended liquid particles during the heating stage.

Title: Gating circuits for multiplex systems for low level signals
IPC: H04J3/04
Filed: 1962-09-25
Abstract: 992,046. Multiplex pulse signalling; transistor circuits. SYSTEMS ENGINEERING LABORATORIES Inc. Sept. 25, 1962 [Sept. 25, 1961], No. 36450/62. Headings H3T and H4L. In a time division multiplex system each input channel is provided with a transistor gating circuit for converting low level D.C. input signals into A.C. signals prior to the sequential. amplification thereof. Four identical input channels 25-28 are illustrated and gating circuit details 5 shown for channel 25. In circuit 5 one input conductor 51 is connected to the emitter of transistor 60 and via primary winding 63 of transformer 70 to the collector of transistor 61. Similarly the other input conductor 52 is connected to the emitter of transistor 61 and via primary winding 62 to the collector of transistor 60. Sequential energization of transistors 60 and 61 is effected by respective switching transistors 54 and 55 controlled by pulse generators 65, 66. Since the primary windings 62 and 63 are wound in opposite directions a D.C. signal from input source 1 gives rise to an A.C. signal in the secondary winding 21 of transformer 70. Gating circuits 6-8 operate in similar fashion and the control pulse generators are programmed, Fig. 3 (not shown), so that output signals appear in turn across the secondary windings 21-24. These signals are coupled sequentially via switches 29-32 and capacitor 33 to A.C. amplifier 34. The resulting high level signal is rectified by a known switching device 39, 40 operated in synchronism with transistor switches 60, 61 &c. and amplified further by D.C. amplifier 41.

Title: Improvements in or relating to borate pigments
IPC: C09C1/36
Filed: 1961-10-12
Abstract: A barium titanium borate compound BaO,TiO2,B2O3 is prepared by heating a mixture of either (1) titanium dioxide and barium metaborate or a mixture of barium and boron compounds convertible to barium metaborate by heating e.g. barium sulphide, carbonate or hydroxide with boron trioxide or boric acid, or (2) barium titanate and boron trioxide or a boron compound convertible to the trioxide upon heating.  The titanium dioxide content of the resulting product does not exceed 26,4% by weight.  The heating is carried out between 700 DEG -1300 DEG C. for 10 mins.-24 hours.  The titanium dioxide used may be anatase, rutile and titanium dioxide ores or it may be prepared by precipitation in the hydrous form from titanium tetrachloride or sulphate solutions e.g. titanium tetrachloride may be added dropwise to crushed ice in a bath after which aqueous ammonia is added and the whole maintained at 10 DEG -20 DEG C. until no further precipitation occurs.  The barium metaborate may be precipitated by reacting solutions of barium sulphide or hydroxide with sodium tetraborate.  Example 1 refers to the above stoiciometric quantities of barium carbonate, boric acid and hydrous titanium dioxide being ground in a mortar and pestle and fired at 1100 DEG C. for 1 hour.  X-ray analysis of the resulting crystalline product indicated that a compound had been formed.  Example 3 refers to equal molar quantities barium sulphide in solution and titanium dioxide together with an amount of borax equivalent to half the molar quantity of the barium sulphide, being refluxed for 4 hours.  The resulting mass was dried at 140 DEG -150 DEG C., ground and fired at 900 DEG C. for 2-3 hours. Specifications 813,228 and 879,499 are referred to.

IPC: H03K6/04
Filed: 1954-12-20
Abstract: 762,059. Electric analogue calculating apparatus. CINEMA-TELEVISION, Ltd. Dec. 20, 1954, No. 36746/54. Addition to 761,461, [Group XL (c)). Class 37. [Also in Group XL (c)] The invention relates to circuits for producing an electrostatic deflection field proportional to the algebraic difference between two voltages such as a sawtooth voltage and a voltage for correcting for the geometry of a television picture tube or a sawtooth voltage and a variable D.C. voltage for varying the region scanned in a storage tube. According to the invention, the circuit comprises two equal load resistors 3, 4, each connected in series with a controlling valve 1, 2 and one of a pair of equal resistors 5, 6, a resistive impedance 7 connected between the junction of the resistors and a terminal of the anode current source and two valve circuits 12, 13, 16, 17 each arranged to compare the potential across the series connection of one of said resistors and said impedance with one of the input potentials and to vary the current passed by one of the controlling valves in accordance with the difference potential. As shown, the two control valves 1, 2 are fed from the input voltage sources A and B through cathode coupled comparators 12, 13 and 16, 17, the control valves being coupled by a constant current valve 7 so that an increase in current in one of the deflection coils is accompanied by an equal decrease in current in the other. Negative feedback is applied to the grids of valves 13 and 16 from across the valve 7 and one of resistors 5 and 6 so that the voltages applied to the control valves 1 and 2 are the differences between the input and feedback voltages. In an alternative embodiment (Fig. 2, not shown), the resistors 3, 4 are connected to the anodes of the control valves instead of the cathodes, the control valves being driven through a further amplifier from the anode of valves 12 and 17. In addition, constant current valves replace the cathode resistors 14 and 18. The voltages applied to A and B may be derived by combining two further voltages applied to opposite ends of a resistor connected to the terminals. Valve 7 may be connected to a tap of a potentiometer connected between resistors 5 and 6 so that the position of the beam may be adjusted.

In a liquid density measuring instrument the liquid is kept in a chamber 2 at a level which is a function of its density by means of a float 5 which, when it has displaced sufficient weight of liquid, rises and closes, by contacts 6, the liquid inlet valve; a photo-resistor 16, contained in a block of optically transparent rubber together with a light source 14, receives more light as the liquid level rises, thereby giving an indication of the density. The sensitive face of the photo-resistor 16 is shielded from direct light from the light source 14 and that of a compensating photo-resistor 15 is directed towards the light source, resistor 15 being shown behind the source in Fig. 1. The opposed inner faces 17, 18 of the block are silvered so that as the liquid rises light, internally reflected from the other two faces and reflected from the silvered ones, reaches the photo-resistor 16. The photoresistors may be of cadmium sulphide and the light source a self luminous phosphor excited to luminescence by a radio nucleide or a lamp. Additional photo-resistors in the block and additional blocks may be used. The block may also be made to move by being fixed on or geared to the float so dispensing with a liquid level control arrangement, which in the arrangement shown in Fig. 1 maintains the level against the outlet flow at 4.
