Title: Multi-way rotary valve for a pressure medium
IPC: F16K11/074
Filed: 1973-01-18
Abstract: 1358153 Valves I J CYPHELLY 18 Jan 1973 [25 Jan 1972] 2738/73 Heading F2V A rotary disc distributer valve for controlling the operation of a fluid device 30, such as a motor, comprises a disc 2 having four equally circumferentially spaced blind bores 3, 3<SP>1</SP> and a block 1 having a number of bores 7, sleeves 11, 11<SP>1</SP>, annular grooves 20, 9, 6 and radial grooves 12, 8. The disc is rotated by a handle 14. With the lever 14 in the full line position shown, pressure fluid from a pump 26 is fed via bores 7 to the grooves 6 and leaks between the disc and the block into the sleeves 11, 11<SP>1</SP> which are thus all under the same pressure and the device 30 is not operated. As soon as the lever is moved to the position shown in dotted lines blind bores 3, 3<SP>1</SP> will be partially over the grooves 6 and 5 respectively, thus allowing pressure fluid to flow to the device 30 via conduit 31 and from it to exhaust, via conduit 32. The device is thus operated, a gradual control being possible by suitable movement of the lever 14. The disc is free to move axially and its position is determined by the pressure forces acting on its two forces. Leakage flow through the annular gap 22 flows back to exhaust via the throttle 18, the rate of flow through which thus determines the equilibrium position of the disc. Foreign particles collecting in the gap are removed by increasing the flow through the gap on opening valve 23, which is in parallel with throttle 18, the increased flow from region 19 producing a corresponding increase in the gap 22.

Title: Manufacture of chlorinated meta styrene and its application
IPC: C08F8/22
Filed: 1931-01-28
Abstract: Chlorinated meta-styrene, prepared by treating meta-styrene with chlorine in the dark at a low temperature in the presence of a halogen carrier and a chlorinated organic solvent, is stated to be useful as a resinous constituent of coating compositions.  The products with the highest chlorine content have the lowest viscosities and highest melting points and give films which dry most rapidly; moreover, those prepared from starting materials of the highest molecular weight, such as are obtained by polymerizing styrene in the absence of a catalyst, are most suitable for spraying compositions.  An example is given of a spraying enamel consisting of chlorinated meta-styrene, dibutyl phthalate, chrome yellow, benzene, toluene and xylene in certain proportions.ALSO:Polymerized vinyl-benzene, known as metastyrene, is treated with chlorine in the dark at low temperatures (about 0-25 DEG  C.) in presence of a halogen carrier, such as iron or aluminium chloride, and in presence of a chlorinated organic solvent, e.g. carbon tetrachloride, tetrachloroethylene or tetrachloroethane; water, too, may advantageously be present.  The products, which contain the chlorine in the nucleus, are resinous materials useful as constituents of plastic and coating compositions.  The products with the highest chlorine content have the lowest viscosities and highest melting points and give films which dry most rapidly; moreover, those prepared from starting materials of the highest molecular weight, such as are obtained by polymerizing styrene in the absence of a catalyst, are most suitable for spraying compositions.  Examples are given of the chlorination of meta-styrene prepared by heating a solution of styrene in carbon tetrachloride in the presence or absence of benzoyl peroxide.  An example is also given of a spraying enamel consisting of chlorinated meta-styrene, dibutyl phthalate, chrome yellow, benzene, toluene and xylene in certain proportions.ALSO:Chlorinated meta-styrene, prepared by treating meta-styrene with chlorine in the dark at a low temperature in the presence of a halogen carrier and a chlorinated organic solvent, is stated to be useful as a resinous constituent of plastic compositions.

Patent GB-289560-A (GB)
Title: Improvements in or relating to refractory compositions and method of making same
IPC: C04B35/18
Filed: 1927-02-01
Abstract: 289,560. Withers, J. S., (Vitrefrax Co.). Feb. 1, 1927. Refractory substances.-Mullite, containing 72 per cent or three molecules Al2O3 to 28 per cent or two molecules SiO2, is prepared by the treatment in an electric furnace of a mixture of minerals high in aluminium-silicate content, such as cyanite, andalusite, sillimanite, or pyrophyllite, with an amount of approximately pure alumina necessary to bring the ratio of alumina to silica to the value indicated above. The added alumina may be obtained from bauxite, diaspore or alunite, or may be natural corundum containing fluxes (iron oxide, titania, magnesia lime or alkalies) less than 2 per cent of the total. Silica may be as high as 6 per cent. Where the product is to be used as a refractory lining to resist glasses or enamels of an essentially alkaline silicate character, the porosity may be reduced by the employment of alumina containing potassium oxide and phosphorus pentoxide, such as the residue left as a bye-product in the recovery of potash from alunite. For the manufacture of general refractory ware, such as firebrick for boiler linings, alumina, admixed with these oxides is to be avoided. The ingredients are ground to a fineness of at least 40 mesh and roughly briquetted, or agglomerated into small nodules with thin molasses-water. A three-phase furnace is employed, the pot being one-third filled, broken coke piled on the charge, and the arc struck. Additional charge is fed around the arc, the electrodes being lowered quickly in the pool as it forms. The rapid formation of a deep pool is essential, the elimination of iron and ferro-silicon depending on the fluidity.

Title: Photographic systems
IPC: H03K17/16
Filed: 1972-01-21
Abstract: 1387291 Photographic flash systems HONEYWELL Inc 21 Jan 1972 [22 Jan 1971 (2)]  2921/72 Heading G2A A circuit for a flash photographic system comprises a first 10, 20 subcircuit and a second subcircuit 30 joined by a two-wire link 21, 22, the first subcircuit including a flash light V1 and first means SCR1 and second means SCR2 responsive respectively to first and second voltage changes on the two wire link to fire the flash light and terminate the photographic exposure respectively, the second subcircuit operable to produce a first voltage change on the two-wire link and having a light sensing device LASCR1 and an integrating circuit C8, R13 which produce the second voltage change on the two-wire link when the total quantity of light sensed reaches a predetermined value. The first voltage change is produced by closing switch S 1 which turns on transistor Q2 to cause the voltage at point 21 to fall sharply to zero. This signal is fed through capacitor C4 and resistor R3 to the cathode of thyristor SCR 1 which fires and produces a signal to fire the flash tube V1. Closure of switch S 1 also energizes LASCR1 and the transistor Q3 is turned off by the falling of the voltage at point 21 to zero and allows integrating circuit C8, R13 to commence operation from a datum state of full discharge. When LASCR1 fires, Q2 is turned off and the voltage at point 21 rises sharply. This rise switches on SCR2 producing a signal to fire the quench tube V2 and thus extinguish the flash tube.

Title: Formaldehyde polymers
IPC: C08G2/00
Filed: 1962-01-26
Abstract: Formaldehyde polymers crystallizable in orthorhombic form are prepared by contacting a polyoxymethylene (e.g. paraformaldehyde) in an aqueous medium with an excess of a metastable aqueous formaldehyde solution in the presence of an alkali metal or quaternary ammonium salt of carboxylic acid at a pH higher than 6 and at 20 DEG  to 60 DEG C.  The polymerization may be carried out in a stationary state at 35 DEG C. or continuously be feeding the reactor with a concentrated aqueous solution of formaldehyde, sodium formate and sodium hydroxide and discharging continuously the polymer and a dilute aqueous formaldehyde solution, this solution may be enriched with formaldehyde by direct absorption of the vapours from formaldehyde synthesis and returned to the polymerization process. The continuous process may take place in two stages, a rapid first stage leading to low molecular weight polymers which are recovered and a second slower stage to increase the molecular weight.  The products may be acetylated.

Title: Improvements in or relating to time controlled electric switching devices
Inventor: PHILLIPS KENNETH RICHMOND
IPC: G04C23/16
Filed: 1964-01-24
Abstract: 1,103,701. Transistor bi-stable circuits. SMITH'S INDUSTRIES Ltd. 25 Jan., 1965 [24 Jan., 1964], No. 3097/64. Heading H3T. [Also in Divisions A4 and G3] Timer for domestic electric oven includes a manually settable clock-driven device, Fig. 1 (not shown), having two fixed contact wipers (10, 16) and a third wiper (not shown) below a disc (14), which go respectively to terminals 74, 66, and 68 of a bi-stable collector-base coupled transistor multivibrator connected to operate a relay 62 controlling the oven. The supply lines are fed from a mains transformer through metal rectifiers 53. When no input signal is applied to either base, transistor 54 conducts and transistor 57 is cut off. Relay 62 is not energized. At the set time on scale (23) terminals 74 and 76 are connected and a + -going signal is applied to 54 base through terminal 66. This causes 54 to cut off so that transistor 57 conducts and the relay is switched ON. Later, at the time set on scale (34), terminals 74 and 68 are connected and this cuts transistor 57 off and transistor 54 conducts, the relay being OFF. Capacitor 63 and resistor 54 protect transistor 57 from transient voltages in relay 62. The relay will still be switched on and off in the correct sequence even if the time set on scale (34) is earlier than that set on scale (23), since if a + ve pulse is applied prematurely to transistor 57 through terminal 68 when transistor 54 is conducting this has no effect because transistor 57 is not conducting. A temperature probe for roasting causes a switch 84 to close and a -ve pulse on transistor 54 deenergizes the relay 62. To work the oven without timed operation, switch 83 is closed. This causes a -ve pulse to the base of 57 which conducts to keep the relay energized.

Title: Improvements in and relating to the discharge of molten ash from solid fuel consuming appliances
Inventor: DENT FREDERICK JAMES
IPC: C10J3/08
Filed: 1957-01-29
Abstract: 893,186. Discharging slag. GAS COUNCIL. April 29, 1958 [Jan. 29, 1957], No. 3166/57. Class 51 (1). In apparatus for discharging molten ash from the reaction zone of a combustion apparatus, the ash is discharged from the reaction zone into a conduit, the initial portion of which is of heat-conducting material, is internally watercooled and is sufficiently short to ensure the flow of ash in the molten condition thereover, and over the surface of the remaining portion of which conduit a stream of water flows whereby the molten ash is quenched and delivered from the conduit in a solid granular state. Means for discharging molten ash from a generator 10, Fig. 1, comprise a downwardly inclined conduit leading laterally from the base of the reaction zone to an ash cooling vessel 18 and formed of a hollow metal member having lower and upper walls 19, 20. The inner and higher end of lower wall 19 is formed as a lip 21 which overlaps a part of the upper wall and which is sufficiently short to ensure the free flow of the molten ash. Cooling water is led from a pipe 22 to the space between the walls to form a cooling jacket and continues to flow down the wall 20 so that the ash solidifies thereon and the mixture of ash and water falls into a bath in the vessel 18. The water is separated from the ash by a sieve 26 in the vessel and is recirculated through the conduit by pipes 22, 24 and a pump 23. A lock hopper 27 having inlet and outlet valves 28, 29 may be provided when gasification in the generator is under pressure. In another construction, a vertical metal conduit has the upper portion surrounded by a metal wall 36, Fig. 2, which forms a water jacket 37 between it and the adjacent portion of the wall 35 of the conduit. The upper end of the wall 36 is curved to form an annular lip 38 above the edge of the wall 35. Cooling water is led to the jacket 37 from an ash cooling vessel 39 through pipes 40, 42 and flows over the upper edge of the wall 35 and flows down the inside face.

[Class 40 (v)] A broadcasting aerial for uniform and maximum radiation in the horizontal plane comprises a straight tubular conductor 1, the bottom quarter wavelength of which is recessed in a conducting earthed roof top RT, and comprising radiating half wavelength sections 2 and a halfwavelength section 3 therebetween, the radiation from which is suppressed by a sleeve 4 which is earthed by a half wave - length connection 14 running through the tube 1. The sleeve 4 may be supported at its mid-point by an insulating or metallic ring member R from the tube 1, and an adjustable sleeve 5 at the upper end of the tube 1 is provided to enable the electrical length of the aerial to be varied. A transmission line TL connects the transmitter HFA to an adjustable tapping TP at the base of the aerial. The diameter of the tube 1 is made relatively large, e.g. one fifteenth of a wavelength to enable it to radiate a wide frequency band. In a modification, Fig. 2 (not shown), the aerial has several radiating portions separated by screened portions, the screens being earthed by conductors one or a multiple of half wavelengths long, and the aerial is inductively coupled to the transmission line. The aerials may be extended symmetrically from a centre to form an extended dipole antenna and may be arranged in arrays for additional directivity.

Abstract: 108,130. Taylor, J. D., and Shaw & Co., F. March 6, 1917. Continuous-discharge apparatus, rotary; rotating conveyers.-Relates to continuous action vacuum drying-apparatus of rotary chamber type. Material fed into the hopper 2 is delivered by a recessed rotating plug 3 to a conveyer 7 working in a chamber in the upper part of the jacketed casing 1. The material is carried to the opposite end of the drum and descends a shoot 36 into a rotating conical drum 20 which it traverses under the action of gravity and passes by the shoot 37 and outlet 22 to a closed receptacle 24. Steam is supplied by a pipe 13 to the shafts 8 and 15 of the conveyer and drum respectively and escapes by the pipe 14. The drum carries scoops 21 which continually lift the material and the shaft 15 is provided with heatradiating fins 19. A pump 33 draws off moisture through the pipe 26 and causes it to pass to a condensor 25 fitted with a draw-off pipe 32 &c. The receptable 24 is fitted with a valve 23 so that it can be shut off from the casing when the dried material is being removed. In place of using the receptacle 24, the material may be discharged through a rotating recessed plug similar to that in the feed hopper. In a modification, a series of rotating conical drums are employed, these drums being disposed alternately in reverse positions in a rectangular casing.
