Patent GB-1081795-A (GB)
Title: Inertial device
Inventor: TURNBLADE RICHARD CHARLES
IPC: G01C19/16
Filed: 1965-08-13
Abstract: 1,081,795. Gyroscopic apparatus; accelerometers. INTERNATIONAL STANDARD ELECTRIC CORPORATION. Aug.13, 1965, No.34721/65. Headings G1C and G1K. A device which may be used both as a gyroscope and an accelerometer comprises a case 3 which is rotated in bearings 4 by a motor 2, the case 3 containing a spherical rotor 5 suspended in and driven by a flotation liquid 6 of greater density than the rotor 5, the rotor being located in the direction of its spin axis by the provision of two pockets of a fluid 7 which is less dense than the liquid 6, and located on either side of the rotor 5 in the direction of its spin axis. The rotor 5 may be of brass, and the liquid 6 is preferably mercury in which case the rotor is provided with a protective ceramic coating. The fluid 7 is preferably a gas and may be air, nitrogen or helium. For use as a gyroscope, the rotor 5 is provided with an oblate surface 9' which acts as a mirror for use with an optical pick-off 12, the case 3 being provided with a transparent end window 10'. Any deviation between the spin axis of the rotor 5 and the axis of rotation of the case 3 will cause deviation of the light reflected by the oblate surface 9' and this will be detected by the pick-off 12. The pick-off may be incorporated in a system which slaves the case 3 to the rotor 5. For use as an accelerometer an optical pick-off 8 is provided which co-operates with the spherical surface of the rotor 5 by way of a transparent window 10. Light from the pick-off 8 will be reflected at an angle dependent on the distance of the rotor from the pick-off so that accelerations along the rotor spin axis causing movement of the rotor along this axis can be detected. In a further embodiment a pendulous accelerometer is described in which the rotor 5 is made of two semispheres of different densities e. g. one of aluminium, which may be hollow, and the other of tungsten or titanium. The plane of separation of the semi-spheres is perpendicular to the spin axis and accelerations parallel to this plane will cause tilting of the rotor, which may be detected by providing an oblate surface thereon, co-operating with an optical pick-off. To prevent undesired reversal of the rotor a projection may be provided on the casing along the spin axis to project into a corresponding recess in one semi-sphere.

Title: A process of manufacturing humus products
IPC: C05C3/00
Filed: 1947-12-31
Abstract: In making humus products, as described in Specifications 438,114 and 484,902, by oxidizing recent or fossil organic materials, e.g., sphagnum peat, with air or other oxygen-containing gases at elevated temperature in the presence of water and maintaining the pH value of the reaction mixture between 5 and 9 by adding ammonia, the starting material is pretreated by subjection to a relatively weak oxidation by air or other oxygen-containing gases at a pH below 5.  The pretreatment may be effected under atmospheric or slightly increased pressure at 120 DEG C or below, e.g., in an autoclave.  The pretreated material may be added, preferably continuously, in small amounts to a larger amount of material already being converted to humus, the rate of discharge of humus being equal to the rate of addition of pretreated material.  The material may be cooled, during its conversion, by introducing water and passing extra gas through the reacting mass, e.g., by recirculating a part of the subsequently cooled gas mixture which has passed through the reacting mass.

Abstract: 1492419 Conveying sheets to alternative paths POLYGRAPH LEIPZIG KOMBINAT FUR POLYGRAPHISCHE MASCHINEN UND AUSTRUSTUNGEN VEB 26 Aug 1975 [29 Aug 1974] 35165/75 Heading B8R In a bookbinding machine, folded sheets 12 are fed along a linear path defined by nip belts 1, 2 until they are pushed into open grippers 18 articulated to relatively slowly moving chains 14, the grippers closing, as associated rollers move off a control track 20, and feeding the sheets over a deflecting member 4 to a stack 22. Incorrectly folded sheets cause photoelectric scanners 31, 31<SP>1</SP> and 32, 32<SP>1</SP>, which are separated by the length of a correctly folded sheet, to be simultaneously blocked, this triggering a circuit which releases a sheet brake 24. The brake momentarily retards the faulty sheet, under the action of a cam wheel (28), Fig. 2 (not shown), causing it to be pulled from its associated gripper 18 and then be fed past the deflecting member 4 to a deposit 33, either by the belts 1, 2 or by the succeeding gripper which pushes its rear edge. Test sheets can be similarly deposited under the action of a manual switch or lever. The brake may have rubber or synthetic material sheet engaging members, suckers, abutments or a magnet and counterplate arrangement. Frictional sheet accelerators 13 are provided.

Title: Improvements in or relating to the transmission of two audio channels over a singlemodulated carrier or a single pair of wires
Inventor: THOMPSON PHILIP MARTIN
IPC: H04H20/48
Filed: 1960-10-13
Abstract: 1,007,432. Diplex radio signalling; tunnel diode frequency multipliers. PLESSEY CO. Ltd. Jan. 10, 1962 [Oct. 13, 1960], No. 35177/ 60. Headings H3T and H4L. In a system for transmitting the sum and difference of two stereophonic or like signals either by wire or as modulation on a carrier wave, the audio-frequency sum signal is combined with a sub-carrier amplitude modulated with the difference signal, the percentage modulation being kept below 50% and the amplitude of the modulation being such as to retain the relative amplitudes of the sum and difference signals. The resultant signal consists of a sub-carrier in which the positive and negative half-cycles are modulated independently, one carrying the left-hand signals and the other the right-hand in a stereophonic system. At the receiver the two signals may be recovered separately by oppositely poled diodes. The sub-carrier may be suppressed and a sub-harmonic pilot frequency transmitted whereby the sub-carrier may be reconstituted at the receiver. In one such arrangement, Fig. 7, the 19 kc./s. pilot signal is supplied via filter 11, 12 to a tunnel diode 16 biased to operate as a non-linear amplifier, the output being taken via a filter 14, 15 tuned to 38 kc./s. The application of the system to stereoscopic or two-colour television is suggested.

Filed: 1928-11-29
Abstract: 322,098. Brown, S. G. Nov. 29, 1928. Gyroscopic apparatus.-A gyroscope indicating instrument such as an artificial horizon or zenith finder comprises a number of gyro-wheels 1, 6 connected together by universal couplings in such a way that rotation is transmitted from one to the other throughout the series, the first gyroscope 1 being driven through a universal coupling 3 from a spindle 2 and the last gyroscope 6 carrying the mirror 7 or other indicating device. The Figure shows a series of only two gyroscopes, the fork 4 for the universal coupling 5 being carried by the gyroscope 1. The masses of the several gyroscopes are so disposed that, considering any number of them from and including the last, the centre of gravity of the combination substantially coincides with the cardan point of the coupling through which the first of the number considered is driven. Thus in the arrangement shown the combination 1, 6 is staticallv balanced about the centre of the coupling 3 and the gyroscope 6 is balanced about the centre of the coupling 5. The spindle 2 may be mounted in a pendulous frame as described in Specification 316,380. Specifications 261,117 and 274,980 also are referred to.

Patent GB-760955-A (GB)
Title: Production of hydrogen
Inventor: LEWIS EMIL H
IPC: C01B3/38
Filed: 1953-12-19
Abstract: In the production of hydrogen by reacting a hydrocarbon in the gaseous state with steam in a first reactor to form a mixture of hydrogen, carbon monoxide and carbon dioxide, with further steam in a second reactor to convert the carbon monoxide to dioxide, and then removing the carbon dioxide, a C1-C4 hydrocarbon gas containing olefins and sulphur compounds is purified for use in the process by adding hydrogen, hydrogenating in the presence of a sulphur resistant hydrogenation catalyst, whereby the olefins are at least partially saturated and the sulphur is at least partially converted to hydrogen sulphide, and removing the hydrogen sulphide.  The hydrocarbon gas may be refinery waste gas, may consist entirely of olefins and may contain any amount of sulphur.  The hydrogen added may be a portion of the hydrogen product or a tail gas, e.g. from a hydrofining or hydrodesulphurization unit in an oil refinery process.  The amount of hydrogen added should preferably be at least stoichiometrically equivalent to the olefins present, more preferably in 50 per cent or more excess.  Hydrogenation catalysts specified are the oxides and sulphides of iron, nickel, cobalt, chromium, molybdenum, copper, manganese and tungsten, molybdates, thiomolybdates and thiotungstates.  The preferred catalyst is 3-25 per cent cobalt molybdate supported on alumina. The catalyst may be mixed with bauxite, zinc oxide, clay balls or fuller's earth.  The temperature of hydrogenation should be between 550 and 850 DEG F., a temperature of 600-800 DEG F. being suitable.  The pressure may be atmospheric to 100 p.s.i.g., preferably 25-50 p.s.i.g.  The gases may be passed alternately through 2 chambers each containing 3 beds in series, cooling water being injected between each bed.  The product gases may be passed in heat exchange with the cold feed gases.  The fluidized bed technique may be employed and inert heat transfer solids such as mullite, corundum and alundum may be circulated through the bed. The hydrogen sulphide produced may be removed by washing with caustic soda.  Alternatively or in addition the hydrogen sulphide may be moved by the use of zinc oxide in admixture with the hydrogenation catalyst.  The resulting hydrocarbon may be reacted with steam in the presence of nickel oxide first at 1000 DEG F. and then at 1600 DEG F. In the first stage of the catalytic reforming process the gas may be passed through a plurality of annular catalytic reaction zones comprising inner and outer tubes heated in furnace (the Fig., not shown), the gases being passed into the annular space and out through the inner tube.  The resulting gas mixture, consisting of hydrogen, steam, carbon monoxide, and carbon dioxide may be passed over iron oxide at 750 DEG C. for the interaction of steam and carbon monoxide to produce carbon dioxide.  The resulting gas may be cooled to remove water vapour, and scrubbed with 10-20 per cent mono-ethanolamine solution to remove carbon dioxide.

Title: Improvements in or relating to the production of rock wool products
IPC: C03B37/06
Filed: 1938-12-05
Abstract: 521,525. Making rock or mineral wool. McCARTY, J. D., and RICHARDSON, C. D. Dec. 5, 1938, No. 35418. [Class 56] A method of making rock wool consists in melting the raw material in a cupola furnace the heat of which is used to generate the steam that shreds the molten material, the shredded material being blown into a chamber which is provided with adjustable side walls and with a conveyer for removing " shot." A binding material and oil may be introduced into the steam before shredding takes place, and a device may be provided for forming the wool into sheets. The furnace comprises a melting-chamber 1 on which is superposed the boiler 2 and a device 3 for preheating the air for the combustion in the furnace. The steam passes to a nozzle 7 arranged in a conduit 17 into which the molten material passes, and the shredded material or " wool collects in a chamber 18. A mixture of starch with borax and water from a tank 11, and oil from a tank 14, may be fed into the steam pipe to be mixed with the wool. The chamber contains two conveyers 20, 21 which move in opposite directions. The conveyer 21 receives the " shot " and carries it to a receptacle 22, while the conveyer 20 receives the wool and carries it out of the chamber. The sides of the chamber are adjustable to enable the wool to settle evenly on the conveyer. The wool may be carried by the conveyer under pressure rollers 23 which form it into a sheet, and the sheet is passed through a drying. oven 24 supplied with hot air from a heater 25. The sheet then passes to cutting knives 30 to be trimmed to a predetermined width, and a planing device 34 may be provided to reduce the sheet to a required thickness.

Title: Improvements in or relating to subscribers' relay-less circuit arrangements for use in a telecommunications installation
IPC: H04Q3/00
Filed: 1958-11-05
Abstract: 877,426. Automatic exchange systems. SIEMENS & HALSKE A.G. Nov. 5, 1958 [Nov. 7, 1957], No. 35550/58. Class 40 (4). In a system in which each subscriber's line a, b, Fig. 1, is connected by way of rectifiers G1, G2 and resistors R3, R41, R42 to potentials U0 and -U2 for the purpose of call detection, both rectifiers are brought into the non-conductive condition by applying the potentials -U2 and U0 to test wires c and d respectively when the line is seized by a line finder AS or a final selector LW, the arrangement enabling the speech potential applied to the line to be reversed without affecting the non-conductive condition of the rectifiers. As shown, the test wire d has the potential -U2 when the line loop is open so that the line circuit is free to a final selector, while point M has the potential U0 which cuts off rectifier G3 in the circuit of a call detector A common to a group of lines. When the subscriber calls by closing switch hu, rectifiers G1 and G2 are conductive and the wire d and point M take up potentials intermediate U0 and -U2. The call detector A is then operated by the intermediate potential -U1 and starts a line finder AS. At the same time the potential on wire d busies the line to final selectors. When the intermediate potential on wire d is found, a testing device (not shown) stops the switch and closes contacts p1, p2 and g1, g2. The former contacts connect busying potentials -U2 and U0 to the test wires c and d respectively so that rectifiers G1 and G2 are cut off, the potential U0 on wire d also rendering a rectifier G4 conductive whereby rectifier G3 is cut off and the call detector A released. The potentials -U2 and U0 are also connected to the line wires a, b over a feed relay S, the resistance of the relay windings ensuring that a lower potential difference is available between the two line wires. This reduced potential is without effect on the rectifiers G1, G2 despite any polarity reversal in the line circuit. It is stated that the total resistance of R3, R41 and R42 should equal the resistance of the closed subscriber's loop. In a modification, Fig. 2, the call detector A is connected in a series circuit comprising resistor R3, rectifiers G1, G2 and the subscriber's loop, and a single resistor R4, the operation being substantially as previously described.

Title: Sealing arrangement for the sealing of surfaces moved parallel to one another, more especially to a shaft seal packing
IPC: F16J15/34
Filed: 1959-10-22
Abstract: 930,821. Stuffing-box substitutes. H. SCOBEL. Oct. 22, 1959 [Oct. 29, 1958], No. 35799/59. Class 122 (5). A seal employing two relatively-movable members 5, 10, Fig. 1, having their coacting surfaces 7, 9 urged towards one another by springs 8 has one or more passages leading towards and terminating at one of these surfaces for the passage of a pressurized lubricating medium, the flow of which is substantially constricted so that the two surfaces are forced apart to form a very small gap which avoids direct contact between the surfaces and allows the flow of medium into the gap. As shown applied to a rubbing-collar type seal, the surface 9 is formed on a ring 10 secured to a housing 11 and coacts with the surface 7 formed on a ring 5 which is slidably mounted on a ring 3 secured to a shaft 1 and loaded by the springs 8. The lubricating medium is fed through one or more ports 15 leading to the bottom of a groove 12 which receives a porous ring or segments 13 formed of carbon, ceramic material or sintered metal and constituting the constricting means for the medium as it passes to the surface 9. In the modification shown in Fig. 2, the porous ring 17 is located above a shoulder on the ring 10 so as to provide a gap 21 for the entry of the lubricating medium and the outer surface of the ring 17 is sealed off by an impermeable layer 18; this arrangement may be further modified by dispensing entirely with the layer 18 or providing it only on the lower portion of the ring or by locating the ring 17 so as to dispense with the gap 21. In a further modification, the lubricating medium is fed into the gap through drilled holes, slits or grooves serving as constricting means instead of the porous ring. If desired, the lubricating medium may be fed through passages leading into both the contacting surfaces 7, 9. The lubricating medium may be a gas or liquid and either the same as that being sealed off as is the case in the example shown in Fig. 1, or a separate medium which is then supplied by a pump and serves as a barrier seal in the gap between the surfaces 7, 9.
