Title: Resinous compositions
IPC: C09D123/16
Filed: 1965-04-07
Abstract: A composition comprises an unsaturated glyceride oil and a substantially amorphous interpolymer of a multi-unsaturated hydrocarbon and at least one monoolefin, the interpolymer having an essentially saturated carbon chain as the polymer backbone, containing therein a substantial proportion of the total carbon atoms in the polymer molecule, is soluble in hydrocarbon solvents and contains sufficient ethylenically unsaturated groups in the polymer molecule to permit substantial curing of thin films thereof by an oxidative mechanism.  The oil may be any natural or synthetic drying, semi-drying or non-drying oil which contains glycerol esters of unsaturated fatty acids and can be added to the interpolymer prior to or during polymerization or to the preformed interpolymer.  The compositions may be utilized in an organic solvent, or water-in-oil, or oil-in-water emulsion, and may contain plasticizers, pigments, and conventional additives. Curing which takes place at normal temperatures can be accelerated by heat or conventional metal driers. Exemplified compositions are a mix of an ethylene-propylenedicyclopentadiene interpolymer, a small amount of a metal naphthenate and an oil selected from linseed coconut, raw castor, soybean, safflower or dehydrated castor.  The compositions are used to coat substrates of metal, wood, glass and plastics, e.g. polyesters.ALSO:Substrates of metals, wood, glass and plastics are coated with a composition comprising an unsaturated glyceride oil and a substantially amorphous interpolymer of a multiunsaturated hydrocarbon and at least one monoolefin, which is soluble in hydrocarbon solvents and which contains sufficient ethylenically unsaturated groups in the polymer molecule to permit curing of thin films thereof by an oxidative mechanism.

Title: Improvements relating to Centrifugal Separators for Separating Solid and Liquid Mixtures.
Inventor: MAUSS WILHELM
IPC: B04B11/04
Filed: 1917-10-12
Abstract: 119,706. Mauss, W. Oct. 12, 1917. Strainer separators; driving and suspending; baskets or drums; charging and feeding.-A drum, comprising axially separable sections, is supported by means including a toggle for keeping closed the drum during separation of the liquid. Means are provided for automatically charging the drum, discharging the liquid separated to one outlet, lowering the drum, opening the drum to discharge the solids, closing the drum and raising it to its working position. The drum comprises two conical sections 1, 2 carried respectively by the shaft 11 and the tubular shaft 18. Filtering material is arranged behind perforated plates 5 sunk in the walls of the cones, and liquid passages behind the material communicate with outlets 8, which discharge into a receiver 9. A cross-head 12 on the shaft 11 and a cap 29 on the shaft 18 are connected by toggle-levers 27, 28, the central joints of which are linked to a yoke 39 suspended in a bearing in the barrel 37, which is supported from a lever 34 connected to the piston of a hydraulic cylinder 32. In the separating position, as shown in Fig. 1, the links 41 keep the toggle extended, tending to resist separation of the cones 1, 2. Water is caused to flow from a pipe 54 at such a rate that, when the separation of a charge is completed, the pivoted tank 53 overbalances and trips the valve 49 controlling the fluid supply to the cylinder 32. The lever 34 is rocked to lower the yoke 39 and the drum is lowered, as a whole, clear of the outlet 9. The shaft 18 then rests on supports in the casing 20 and the further movement of the lever 34 opens the toggle and allows the cone 2 and shaft 11 to move further down and opens the joint between the cones 1 and 2 for discharge of the solids. The tank 53 is reset by the rod 55 and the valve 49 then reverses the stroke of the piston in cylinder 32, so that the drum is closed and then raised. At the end of its stroke, the forked rod 47 rocks the lever 43 and this lever carries the rotating drum so as to relieve the bearings in the barrel 37. The means for charging the drum comprises a tank 57 into which the mixture flows through an opening 58. A plunger 59, fitted with valves 60, is raised by the cyilnder 62, the fluid supply to which is controlled by the valve 66 actuated from the beam 34, and by a valve 64 tripped by tappets connected to the piston 61. When the empty drum is raised, the plunger 58 raises the mixture in the tank 57 which flows by way of the launder 16 to the drum.

Title: Improvements in fluid controls particularly for turbine engines
IPC: F15C1/00
Filed: 1966-04-04
Abstract: 1,133,591. Fluid-pressure servomotor system; fluid analogue system. GENERAL ELECTRIC CO. April 4, 1966 [May 19, 1965], No.14789/66. Headings G3H and G3P. A fluid control system for a gas turbine engine comprises a fluid generator 40 producing a fluidpressure frequency proportional to the speed by rotating an inclined plate 44 to control the leakage from pipes 34, 36 which are supplied from an inlet 26 through equal restrictors 30. The frequencies produced in the pipes 34, 36, which are 180 degrees out of phase, act as control signals to a fluid amplifier having outlets 52, 54. The outlet 54 is connected to a resonance chamber 60, the volume of which is adjustable by an operator to set the required engine speed. When input frequency is the same as the resonance frequency the output 64 is at maximum strength with no phase shift; if the input frequency varies from the resonance frequency, the output signal is sharply attenuated and lags or leads depending on an increase or decrease in the frequency. The output from the chamber 60 is fed to a decoupler 14 which eliminates any steady state or slowly fluctuating pressures by causing the output of the chamber 60 to split into control signal passages 74, 84 of an amplifier 16. The input 72 to the decoupler is passed through passage 74 and into a large chamber 82 to the passage 84. The chamber 82 will attenuate the pressure frequency so that there will be no pressure variations in the control passage 84 due to the frequency. The outputs of amplifier 16 are used as control signals for a further amplifier 18 which contains chambers 108, 110 to provide a change in the phase of the signals such that the output signals from amplifier 18 are normally 90 degrees out of phase with the output signals in outlet 52 of generator 40. The outputs 122, 124 of the amplifier 18 form control signals 136, 142 of amplifiers 123, 125 of a discriminator 20, the other control signals 140, 138 being connected to the output 52 of the generator 40. When the frequency varies from the frequency of the resonance chamber 60, the net effective force due to the control pressures 136, 138 and 140, 142 causes a difference in pressure between the receivers 133, 135 and thus produce an error signal in a transducer 25 controlling the fuel valve. When it is required to vary the speed with the inlet temperature at the turbine, air is drawn off and passed through the resonance chamber 60.

Title: Pipe or hose couplings
IPC: F16L37/133
Filed: 1971-05-13
Abstract: 1379519 Pipe couplings SPP GROUP Ltd 16 Dec 1971 [16 Dec 1970 13 May 1971] 59798/70 and 14794/71 Heading F2G On bringing pipes 6 and 14 together, collet 2 enters pipe 14 and, on being retracted, relatively to pipe 6, is expanded by the wedging action of the rim 26 of a stationary ring 24, so that the retraction (from the position shown in the lower part of Fig. 1, to that shown in the upper part of the Fig.), not only positions step 16 for interengagement with shoulder 20, but also, through continued action, compresses sealing ring 38 against the end face of shoulder 20. Resilient fingers 4 of the collet 2 are held against rotation, while ring 8 is turned, by means of lever 36 and pinion 32, to effect retraction by screw action. On reversing the direction of rotation of the ring 8, fingers 4 spring inwardly to unlock the coupling. In another form, the collet is constructed of rigid segments (40, Figs. 3-5, not shown), which are resiliently urged inwardly by means of a garter spring. The coupling may be used with different sized large bore fuel oil hoses for bunkering purposes.

Title: Improvements in or relating to television systems
Inventor: BASS PATRICK
IPC: H04N7/16
Filed: 1963-04-16
Abstract: 1,041,405. Subscription television system; line transmission system. R. & R. RESEARCH Ltd. April 3, 1964 [April 16, 1963], No. 14809/63. Headings H4L and H4R. In a subscription television system, which is stated to be of use with either wire or radio distribution, the transmitter transmits audio and video signals modulated on respective carriers 1 and 2, Fig. 14, together with interference carriers 3 and 4 which serve to inhibit proper reproduction by an unauthorized receiver, a receiver for use with the system being provided with filter means to eliminate the interference carriers. Thus a receiver may have filter means with a transmission characteristic as illustrated in Fig. 1B which normally serves to reject the carriers 1 and 2 but which may be changed to have a characteristic as illustrated in Fig. 1C whereby the interference carriers may be rejected. Such a receiver is shown in Fig. 2 where incoming signals at 5 pass to a reproducer 12 by way of either filter means 11 or filter means 13 as determined by the setting of contacts 9, 10 of a relay 7 which is controlled by a coin box or debit indicating mechanism 8. As an alternative to the use of two filter means, only one may be provided together with means for changing the characteristic, e.g. by adjustment or insertion of a capacitor. Reference is also made to a system in which a fixed payment is made for the use of the system but only certain receivers in the system contract to use the facility. For this purpose all the receivers are provided with filter means, those in contracting receivers having a fixed characteristic as in Fig. 1C and those in the other receivers having a fixed characteristic as in Fig. 1B. Interference carrier 4 may be spaced from carrier 2 by 0.5-0.75 Mc/s.; the spacing of carriers 3 and 4 may be the same as the spacing of carriers 1 and 2. The interference carriers may be modulated by a signal at a frequency, e.g., 10 c/s., below television field frequency, or by. price information, programme identification and audio announcement signals. The frequencies of the carriers may also be changed from time to time. The amplitude of the interference carriers may also be made greater than that of carriers 1 and 2 so that when they are not rejected they cause the receiver automaticgain-control to suppress picture and sound reproduction. The system may include the pricing and recording arrangements disclosed in Specification 1, 010, 081.

Title: Improvements in machines for manipulating cut tobacco
IPC: A24C5/34
Filed: 1956-05-15
Abstract: 860,184. Automatic control systems for cigarette - making machines. POWELL, G. F. W., and MOLINS MACHINE CO. Ltd. May 14, 1957 [May 15, 1956], No. 15063/56. Class 38 (4). The rate of feed of tobacco to a cigarette-making machine is maintained constant by the use of a radio-active source 7 (see Fig. 2), and an ionization chamber 6, disposed on opposite sides of a moving mass of the tobacco, the output from which chamber (described in more detail in Specification 860,187) is balanced against that from a similar device 9, constructed as described in Specification 860,188, and producing a reference voltage corresponding to the desired feed rate. The difference in these outputs is converted to an alternating voltage by dynamic condenser 21 and fed to amplifier and phasesensitive detector 22; differences from zero of this output are indicated on meter 23, and when large enough close contacts of a relay 24 which operate through transistor amplifiers to control a reversible motor 42 (see Fig. 3), coupled to a continuously variable gear as described in Specification 860,185, so as to adjust the tobacco feed rate. A " check zero " button 29 operates relay 31 to apply a negative voltage to the bottom of resistor 20 to compensate for removal of tobacco from the feed line in the region of ionization chamber 6; the potentiometer 33 is preset to make meter 23 read zero under these conditions, when the apparatus is functioning correctly. Fig. 3 shows transistors 38, 39 controlled by relay 24 and operating relays 40, 41 with contacts 43, 44 controlling the energizing of the windings of a reversible motor 42; the relays 40, 41 also switch on lamps 46, 48 indicating the control action. When the deviation of the feed rate becomes excessive, relay 25 operates to close contacts in the circuit of relay 49, which breaks the supply to motor-controlling transistors 38, 39 and prevents automatic regulation; it also operates warning light 51 fitted with flashing device 52. Automatic operation may be restored by switch 54. A chart recorder may be plugged in at 56. Figs. 8 and 8A (not shown) of the drawings accompanying the Provisional Specification show in more detail the circuitry of an arrangement closely resembling that described above. Specifications 618,774, 620,179, 781,041, 781,867 and 805,044 are referred to in the Provisional Specification.

Abstract: 515,069. Purifying oils. GIRLING, H. E. (Representative of ELKINGTON, H. D.). (Naamlooze Vennootschap de Bataafsche Petroleum Maatschappij). May 23, 1938, No. 15352. [Class 91] Naphthenic acids are removed from mineral lubricating oils and lubricating oil fractions by contacting the oils in the vapour phase at temperatures between about 300‹C. and 450‹C. with catalysts entirely or substantially consisting of mixtures of oxides and/or carbonates (solid at these temperatures) of, on the one hand, lithium, sodium and/or potassium, and on the other hand of magnesium, calcium, strontium and/or barium, or of substances capable of forming such oxides or carbonates under the reaction conditions. Steam or other gas and reduced pressure may be employed to assist vaporization. The' catalysts may be employed on carriers, such as carbon or metals (for example copper gauze and steel wool) ; other catalysts may also be present, as for example oxides of copper, silver, zinc, cadium and manganese, serving as activators. A large surface area is obtained by finely grinding the oxides and/or carbonates or by preparing from the hydroxides or acetates. An active catalyst is prepared by heating the double compound of magnesium carbonate and potassium carbonate (Engel salt). In an example, a Venezuelan lubricating oil distillate mixed with a little steam is passed at 400‹C. and 50 m.m. pressure over a catalyst consisting of a mixture of anhydrous soda and voluminous magnesium oxides. Specification 496,779, is referred to.
