Title: Production of continuous fibres of heat-softenable mineral material
IPC: C03B37/02
Filed: 1965-05-19
Abstract: Apparatus for the production of continuous glass fibres within an enclosed room, comprises glass feeders arranged in rows along opposite side walls of the room and associated with units for lineally attenuating the glass from the feeders into fibres and collecting the fibres below the feeders, with such units also arranged in rows along the opposite side walls, and is characterized in that means are provided for supplying air under pressure into the room from overhead air inlets extending lengthwise of the room between the rows of feeders and for exhausting the air from the room adjacent the bottoms of the side walls.  Molten glass from a feeder 30, Fig. 3 (not shown) is attenuated into fibres in the usual manner on to double colletts 21a by a winder 20.  Feeders 30 are arranged in rows along opposite side walls of a room 50 the attenuating units being similarly arranged in a lower room 60.  Conditioned air at 1000 to 1500 c.f.m. is fed from a main duct through conduits 41a, 41b to outlets 19a, 19b on either side of both banks of feeders and to outlet 19c in the centre of the room.  Louvres 35a, 35b, 35 are so angled in those outlets as to direct the air flow in the same path as the fibres, both fibres and air passing through shaped openings 23 along the sides of the floor 29 of room 50. Special troughs 17, 25 (Fig. 4, not shown) channel the air flow past the attenuating units through an opening 26 into an exhaust chamber 70 below. Here the air is exhausted to atmosphere or may be reconditioned and recirculated. The air is conditioned so that at level 50 the temperature is 80 DEG F. and the relative humidity 66%, special sensing devices being used to detect any changes.  Water cooled channels 51a, 51b on either side of, and at the lower level of, the feeder orifice tips provide a cooled surface in that region and prevent heat from the feeder increasing the forming room temperature.

Filed: 1975-05-19
Abstract: 1515126 Seat belt retractor ACIERS ET OUTILLAGE PEUGEOT 19 May 1975 [24 May 1974] 21230/75 Heading A3V  A safety belt retractor for an automobile comprises a support 3 in which is rotatably mounted a mandrel 4 around which belt C is wound under the action of spring 7, an acceleration detector, mounted on a rocker 23 which is freely suspended from support 3 and whose centre of gravity is offset with respect to the axis of rotation of the mandrel, actuating locking means preventing mandrel rotation when the vehicle acceleration exceeds a predetermined value. Ribs 15 of flywheel 13 engage grooves 16 in plate 10 which plate rotates with mandrel 4. Rapid belt unwinding causes relative angular movement of plate 10 relative to flywheel 13 against the action of spring 19, rollers 18 rise along surfaces 17b of notches 17 of plate 10 into teeth 12 of ring 11 fixed to support 3, preventing mandrel rotation. Sudden vehicle acceleration or deceleration causes pendulum 28 to swing and pawl 32 to enter teeth 14 to lock flywheel 13. Rocker 23 is suspended from bearing 22a on support 22 and has a mass 26 which hangs vertically and is toothed at 33 to mesh with a gear and flywheel assembly for absorbing or damping the swinging of rocker 23 e.g. by Foucault currents. Retractor 1 is housed at (2) Fig. 1 not shown, in seat(s) and anchorage points (P, Q) are integral with the seat.

Title: Method and apparatus for filling containers with liquids
IPC: B67C3/06
Filed: 1971-04-19
Abstract: 1334439 Filling containers HOLSTEIN & KAPPERT MASCHINENFABRIK PHOENIX GmbH 19 April 1971 [7 Feb 1970] 21314/71 Heading B8T A method of filling containers with foamdeveloping liquids comprises partially filling a container, stopping the supply to allow foam to dissipate, and then completing the filling. A filling device comprises a storage container 7, and a number of filling elements 1 each comprising a filling tube 2 and a gas conduit 5. A container 15 is located beneath an element 1 and is prepressurized to the saturation pressure of the liquid by means of a conduit 13. A stop valve 10 opens to allow liquid from the container 7 to pass into the container 15 by way of a conduit 6, branch conduit 8 and throttle valve 12. When the liquid rises slightly above the outlet 3 of the tube 2, the filling is stopped to allow foam to dissipate, after which more liquid is introduced, at a higher pressure, by way of stop valve 11. Any excess liquid and foam can return to the container via the conduit 5 and a return conduit 14. In further embodiments, the container 7 is formed as a ring chamber, and the elements 1 are located on a rotary filling machine.

Title: Improvements in and relating to the distillation of hydrocarbons
IPC: C10G7/00
Filed: 1945-08-21
Abstract: <PICT:0597472/III/1> Sulphuric acid-washed hydrocarbons are mixed with strong aqueous alkali and the mixture is passed, preferably under pressure, through a heated coil; the hydrocarbons are then separated from the alkali and subjected to distillation.  The treatment, which is particularly useful in refining crude benzole, eliminates corrosion of the distilling plant due, in the absence of such treatment, to sulphur dioxide derived from neutral sulphur compounds formed from the sulphuric acid and certain components of the crude material.  Benzole, withdrawn from acid-washing tank 4, storage tank 6 or still 1, is pumped, together with caustic soda solution withdrawn from separator 8, through steam heated coil 9. The heated mixture passes into chamber 10 from which the vapours evolved are led through line 12 into still 1.  The liquid in chamber 10 flows into separator 8 where the oil and caustic soda solution separate, and the former is introduced into still 1 through line 11.  The process is also applicable to the treatment of acid-washed petroleum, creosote oil, naphthalene and anthracene.

Abstract: 726,501. Hat stretching apparatus. FAILSWORTH HATS, Ltd., and SYDNEY, E. July 31, 1953, No. 21328/53. Class 63. In hat stretching apparatus, pivoted elements 12 engage within the hat and cam, lever and eccentric mechanism impart successive spreading and contracting movements to the elements 12 in such a way that the extent of each spreading movement is greater than that of the contracting movement, whereby the spreading effect gradually increases. The hat engaging elements 12 are pivoted to the framework at 10 and carry rollers 14 which are engaged by a conical head 9 on a shaft 16 reciprocally mounted in the framework. A lever arm 18 is pivotally mounted on a spindle 17 and carries at one end a pivotally mounted bell crank lever 19, one arm 20 of which is connected by links 22 to the end of the shaft 16, whilst the other arm 26 is linked by a connecting rod 28 to a strap 30 of an eccentric 31.

Abstract: 438,418. Free - piston compressors. JUNKERS, T., (Representative of JUNKERS, H.), 18, Hindenburgstrasse, Gauting, Munich, Germany. July 30, 1935, No. 21606. Convention date, Aug. 11, 1934. [Class 8 (i)] For starting a multi-stage free piston compressor by compressed gas admitted to the compressor side of the apparatus a gas is employed with pressure greater than that of the final compression pressure and is admitted to one or more but not all of the compressor stages. When starting gas is to be admitted to the high pressure unit there is fitted an admission chamber 31 connected by a pipe line 32 with the storage supply tank 34 and in valved communication with the cylinder 6. The valve 28 carries on its stem a larger piston 29 which is under spring control 30 and has a balanced connection by means of a connecting pipe containing a loaded valve 35 with the chamber 31. On opening the valve 33, starting gas is admitted past the valve 28 to move the piston 4 and thereafter is closed by the redistribution of pressure on the piston 29. In some cases, the valve is provided with a small aperture to provide a slow leak, and a similar leak aperture 38 is used for the chamber 36. When the engine starts a portion of the re-compressed starting air is discharged past the valve 41 which has an adjustable spring 27. In a modification, further valved connections are employed so that the working cycle is established after the first double stroke. In a further modification, the parts are held in the starting position by a pawl which is controlled by the starting gas and released in proper sequence. This pawl is itself restrained from re-locking the parts during the working period.
