IPC: D04H1/00
Filed: 1952-11-24
Abstract: 723,724. Moulding resin-glass from fibre preforms. OWENS-CORNING FIBERGLAS CORPORATION. Nov. 24, 1952, No. 29659/52. Class 87 (2). Strands S of glass fibres (each strand comprising, say, 200 individual fibres) are fed from spools 56 over a roller 45 having a resilient surface, where they are cut into short lengths S' by knives 49 on a roller 48, the knives forcing the strands into the periphery of the resilient surface so that the strands are folded over the edges of the knives and all the fibres in the strands are cut in the same place. The cut lengths are then blown along a conduit 35, where powdered resin from a vibrating feed 62 is dropped in at 64 to coat the lengths (or the strand may be initially coated with resin) and into a chamber 16 where they are sucked onto a rotating former 20 to form a layer P. Heat is applied to the layer by electrical or gas flame heaters 68, to cure or set the resin and consolidate the layer into a preform which is used for moulding purposes. A fan 28 effects both the blowing and the suction. A preform having the upper or lower or both surfaces formed of individual fibres (the interior being formed of strands) may be made by varying the speed of the rolls 45, 48, the rolls being rotated quickly at the start of a preform-making operation to open out the strands into fibres, then slowly to form the body of the preform from unopened strands, then quickly; this is effected by adjusting the speed of the electric drive 55, 54 to the rollers. When a preform has been thus made a door 70 in chamber 16 is opened, the preform is removed, the door is closed and another cycle is performed. In modifications, (a) Fig. 3, (not shown) filler is fed in with the resin and (electric) heaters are carried by a frame which is raised whilst the strands are being accreted on the former and then lowered into proximity with the accreted layer; (b) Figs. 6 and 7 (not shown) the resin is set or cured by hot gases blown onto the accreted layer.

Title: Improvements in machines for manipulating cut tobacco
IPC: A24C5/18
Filed: 1953-10-28
Abstract: 783,696. Automatic control systems for tobacco machines. MOLINS MACHINE CO., Ltd., and MOLINS, D. W. Jan. 27, 1955 [Oct. 28, 1953], No. 29802/53. Class 38 (4). In a tobacco manipulating machine in which tobacco is fed from a first conveyer through a compacting passage on to a second slower conveyer, a radio - active detector of the mass per unit length on the second conveyer controls the speed of the second conveyer and a capacity type detector of mass per unit length in the passage, compensated for moisture content variations, controls the speed of the first conveyer. The invention is applied to a cigarettemaking machine of the type described in Specification 646,746, [Group VI], in which tobacco showered from a hopper 1 on to an endless tape 2 is led into an inclined passage 3, the upper wall of which is formed by an endless smooth plastic tape 4 moving faster than tape 2 so that the tobacco is compacted to form a filler which is delivered via a stationary guide 5 on to a cigarette paper web 7 supported and moved by a further endless tape 8 moving more slowly than tape 2. As in Specification 781,042, variations in the mass per unit length of the filler are detected by a radio-active device 15 the output of which controls through an amplifier 16 a -differential gear 23 and a variable-speed gear 18 to correct the variations by adjustment of the speeds at which tape 8 and hopper 1 are respectively driven from a motor 22. In addition condenser electrodes 9 and 10, respectively associated with the tobacco in passage 3 and on paper 7, are arranged in a balanced circuit 30 so that any change in the ratio of the masses per unit length at these two points is detected and a relay 31 operated to run a motor 32 in the appropriate direction to correct the ratio by adjustment of the speed of a motor 35 driving tape 2. The use of two sets of electrodes 9 and 10 eliminates the effect of variations in moisture content of the tobacco. Alternatively electrodes 10 may be dispensed with and the output of radio-active detector 15, suitably modified in dependence on variations in moisture content as in Specification 781,041, may be associated with electrodes 9 to control the speed of tape 2.

Filed: 1926-11-25
Abstract: 281,862. Gardner, E., Gardner, E. E., and Gardner & Sons, Ltd., L. Nov. 25, 1926. Starting. - In starting two-stroke engines in which ignition is effected by the heat of compression of an air charge in the cylinders, compressed air is admitted to set the engine running and then cut off; the ordinary air charges are then admitted and fuel is injected at about the point of maximum compression, the compressed charges being released from the engine cylinders during the expansion stroke prior to the opening of the ordinary exhaust ports, in order to prevent the full fall of temperature resulting from the full expansion of such charges when they are released only by way of the ordinary exhaust ports. In one form, Fig. 1, the cylinder head is provided with a release valve a actuated from an eccentric on the engine shaft through a rod e, levers, f, h on a lay shaft c, and a transmitting member i slidable on a pin j to bring it into or out of the operative position. In a modification, the movable transmitting member is a roller slidable axially, on one end of a valve lever, into or out of position for actuation by a cam. Means such as a throttle valve may also be provided for reducing the amount of the air charge at starting, in order to retain more than the normal residue of the previous charge and so obtain a further gain in initial temperature.

Title: Process for the production of dry, high-grade calcium hypochlorite
IPC: F16C19/40
Filed: 1930-10-06
Abstract: Solid calcium hypochlorite is obtained from solutions thereof having a low concentration of calcium chloride without appreciable loss of available chlorine by imparting to the solution a slight but permanent alkaline reaction by addition or formation of calcium hydroxide, and rapidly evaporating the solution to dryness in a finely divided condition in hot air at atmospheric pressure, as by atomizing or spraying the solution.  A caustic soda solution may be used to produce the calcium hydroxide, and the dry product may be further dehydrated to produce anhydrous crystals, if necessary in vacuo.  Previously concentrated hypochlorite liquors may be used in the process and inert gases, for instance nitrogen, may replace the hot air.  In an example air at a temperature of 130-140 DEG  C. is used, giving a drying temperature of 70-80 DEG  C.

Title: Improvements in fuel supply systems for thermal power plants
IPC: F02C9/40
Filed: 1955-10-21
Abstract: 786,001. Gas turbine plant. GENERAL ELECTRIC CO. Oct. 21, 1955 [Oct. 25, 1954], No. 30185/55. Class 110 (3). [Also in Group XXIX] A dual fuel supply system for gas turbine and other thermal power plants which include a combustion chamber comprises separate fuel lines 4, 5 for supplying two different fuels to the combustion chamber 2, separate fluid-operated control devices 6, 7 for controlling the respective fuel lines, a pressure regulating means 8 for producing a control pressure in response to variations in the operating conditions of the plant and a pressure divider 10 for dividing the control pressure between the devices 6, 7 in a desired ratio. As shown, gas and liquid are supplied through a common nozzle 3 under the control of a gas valve 6 and a fuel pump 7 respectively, the two latter being controlled by the pressures P1, P2 in pipes 12, 13 leading from the pressure divider 10. The latter is fed through a pipe 9 from the pressure regulating means 8 which may be responsive to speed, temperature and pressure conditions of the plant. The pressure divider comprises a housing 17 containing a piston valve 18 movable in a fixed sleeve 19. The valve is adjustable against a spring 38 by a cam 45 on a shaft 39 manually adjustable by a handle 37 or automatically adjustable through gearing by an electric motor under the control of a pressureoperated switch. The valve 18 has three spaced lands 28, 29, 30 controlling a pressure inlet port 23, two outlet ports 22, 24, and two drain ports 21, 25 the latter leading to a common drain line 26 a back pressure in which is maintained by a valve 65 loaded by an adjustable spring 58. The outlet from the valve 65 leads through a line 14 to a reservoir 15. The lands 28, 29, 30 are separated by annular chambers 33, 34. In the neutral position of the valve 18, the land 28 does not cover the port 23 and the orifices 31, 32 so-formed are equal and also equal to the orifices 35, 36 formed between the lands 29, 30 and the respective drain ports 21, 25. In the neutral position of the valve 18, the pressures P1, P2 are equal. By throttling the orifices 31, 36 or 32, 35 more or less the pressure ratio P1/P2 may be varied. When the pressure divider 10 is controlled by a pressure switch, the latter is responsive to the pressure in the gas line 4 upstream of the gas valve 6 and operates to divert more of the control pressure in the pipe 9 to the fuel pump control when the gas pressure drops below a predetermined value.

Title: Improvements in the driving mechanism of centrifuges
IPC: B04B9/08
Filed: 1930-10-10
Abstract: 354,613. Centrifugal machines. AKTIEBOLAGET SEPARATOR, 8, Fleminggatan, Stockholm. Oct. 10, 1930, No. 30372. Convention date, Oct. 12, 1929. [Class 23.] Driving.-Power is transmitted to the bowl of a centrifuge from the driving shaft through an element coupled to the shaft by a friction clutch and mounted outside the frame, and the worm wheel which drives the centrifuge spindle is connected to the driving shaft by an externallyoperated coupling. A worm on the bowl spindle 6 engages the worm wheel 5 rotatably mounted on the shaft 2 supported in bearings 3 on the frame 4. A ring 10 on the wheel 5 contains a split ring element 11 keved to the shaft 2. Associated with the split ring 11 are two levers 13 with arms 13a. When the sleeve 14 is operated by its external handle to move towards the wheel 5 the ends of the levers 13 move so that the arms 13a expand the ring 11 and force it into engagement with the ring 10; this couples the wheel 5 to the shaft 2. A spring 15 may be placed between the levers 13 to effect the closing movement when the sleeve 14 is retracted. The belt pulley 7 is loose on the shaft 2 and carries friction members 8 which are pressed out during rotation to engage the inner rim of the disc 9. This disc is provided with spring- operated pins 16 which operate in grooves 19 of continuously decreasing depth in the disc 18 rigidly connected to the shaft 2. This ratchet coupling becomes effective as soon as the speed of the driving pulley 7 exceeds that of the worm wheel 5, but permits relative motion between the parts when the speed of the bowl exceeds the momentary speed of the pulley. In a modification the ratchet coupling is placed between the worm wheel 5 and the split ring 11.
