Title: Improvements in and relating to the production of artificial filaments
Inventor: EVANS BERNARD HENRY HARPER
IPC: D01D7/02
Filed: 1952-06-30
Abstract: A lid for a spinning box nesting of viscose spinning machines has a central hole for the insertion and reciprocation of a spinning funnel and one or more ventilation holes between the central hole and periphery of the lid so located that the atmosphere entering the nesting is substantially diverted round and not into the spinning box, and also has a floating cover for the central hole, the cover having a hole of sufficient diameter to allow the funnel to make a close but sliding fit which will not impede the reciprocation of the funnel.  A shown, a lid 5 for a spinning box nesting has a <PICT:0730880/IV (a)/1> <PICT:0730880/IV (a)/2> handle 6, a rim 7, a retaining catch 8, a central hole 9 and three ventilation holes 10, 11, 12.  A floating cover 13 for the hole 9 is loosely mounted on the lid 5 by means of a stud 15 on the lid 5 and a slot 14 in the cover 13.  The cover 13 has a hole 16 of sufficient diameter to allow the passage of the stem of a funnel with a close but sliding fit.  The edge of the cover 13 round the hole 16 is turned up to provide a rim 17.  The spinning box nesting may be fitted in a box-spinning machine for the manufacture of artificial threads in which the coagulating bath and spinning boxes are contained in an enclosed space provided with means for introducing steam or sprays of water.  During spinning, moisture-laden air is drawn through the spinning box nesting by a pump in the exhaust duct and passes down through the ventilating holes 10, 11, 12 and around the spinning box between the box and baffles which surround it.  Thus the air does not enter the box, and in this way inequalities in the dyeing affinity in different parts of the cake are avoided.  Specification 546,979 is referred to.

Title: Improvements in or relating to shock absorbers
IPC: F16F9/36
Filed: 1956-05-29
Abstract: 794,304. Pneumatic and hydraulic shock absorbers. REGIE NATIONALE DES USINES RENAULT. May 29, 1956 [July 6, 1955], No. 16623/56. Class 108(3) A telescopic shock absorber comprises a piston 5' (Fig. 1) having apertures 11, 12, for passage of a damping fluid from one side of the piston to the other, and comprising two extensions 17, 18, on each side of a central portion of the piston 5<SP>1</SP>, the extensions 17, 18 being of a smaller diameter than the portion 5' and provided with packing rings 19, 20, each having an air passage notch 19<SP>1</SP>, 20<SP>1</SP> and adapted to engage in respective bores 17<SP>1</SP>, 18<SP>1</SP> formed in the corresponding cylinder heads 1, 2. In Fig. 1, the working fluid is air, which is lubricated by contact with porous material 14 disposed in a bore formed within the piston 5. Oil is supplied to the material 14 by a further porous material 13 from an oil reservoir 7 in the piston rod. The piston may have two packing rings 21, 22 each disposed with their peripheral lips adjacent one another as shown. This results in a friction damping action due to air under pressure forcing itself into a space 24 between the packings. Alternatively, the rings 21, 22, may be disposed with their respective peripheral lips pointing away from each other. The device may be supplied with air under pressure through a valve (Fig. 2, not shown). In the construction shown in Fig. 4, the working fluid is oil, which is maintained under pressure by the action of a pneumatic flexible chamber 43 in the hollow piston rod 5 (left hand side of Fig. 4) or by air behind a floating piston 44 in the hollow piston rod 5 (right hand side of Fig. 4). The arrangement of piston packings 21, 22, is the same in this construction as in Fig. 1. The air reservoir in the hollow piston rod is supplied via a valve 35. In operation of this embodiment, on compression, liquid is forced from the space 23 below the piston through a calibrated orifice 29 into the hollow piston rod 5 through ports 39 into an annulus space 38 between the piston rod and the body 5<SP>1</SP> of the piston, and thence through ports 41 into the space 25 above the piston. Extra damping is afforded on larger shocks, when the extension 18 enters the bore 18<SP>1</SP> in the cylinder head 1. On rebound, liquid is forced from the chamber 25 through ports 40 into the annular space 38 and thence via port 39 and calibrated orifices 29 and 42 to the chamber 23. Damping also takes place through a calibrated orifice 41 between the chamber 25 and the annulus space 38. Damping of excess rebound is increased when the extension 17 enters the bore 17<SP>1</SP> in the upper cylinder head 2.

Filed: 1942-11-30
Abstract: 559,507. Thermal switches. BRITISH THOMSON-HOUSTON CO., Ltd. Nov. '30, 1942, No. 17018. Convention date, Dec. 4, 1941. [Class 38 (v)] A thermal switch for starting electric discharge devices comprises two thermostats, one quickacting, the other relatively slow-acting, responsive to current flow through the lamps, and controlling contacts which break the starting circuit by differential snap action when current is applied for starting and make again subsequently by slow heating of the thermostat. In one example, Fig. 7, the quick-acting bimetal strip 20 is slotted at the free end, in which slot a member 30 moves with a toggle-like action, having a bearing at its inner end on an extension 34 of the slow-acting bimetal strip 21. A stop 36 carries one contact 17 and the toggle member 30 the other 18. Both strips bend under heating, in the same direction, downwards as here shown, the quick-acting strip 20 overtaking and snapping over the toggle 30 under the heating of the lamp and also on cooling. In the example, Fig. 5, the slow-acting strip 21a bears a contact 18a on the face towards the quick-acting strip 20a, and another 18b on its end. On first heating contact 17a on the strip 20a snaps off the end of strip 21a. On subsequent heating and cooling contact is remade with the end contact or the side contact 18a, depending on the position of strip 21a responsive to over-all temperature.

Title: Improvements in or relating to methods of providing thin coherent substantially smooth layers on rough surfaces inside vessels
IPC: H01J29/28
Filed: 1948-06-24
Abstract: A smooth layer is provided on a rough surface inside a vessel by introducing successively a filling liquid to submerge the surface to be coated and on the surface of the filling liquid a solution of lower specific gravity than that of the filling liquid and containing an amount of material for the smooth layer greater than is required, tilting the vessel and decanting the liquid leaving a layer of solution on the rough surface which is then dried.  The filling liquid may be water and the smooth layer nitrocellulose which may be dissolved in butyl acetate alone or mixed with xylene.  A softening agent may be added to the solution.  To provide a smooth layer on a luminescent screen which has been deposited in an electric discharge tube by settling from a filling liquid, the processes may be combined by using the same filling liquid for floating the solution.  The vessels may be closed with stoppers preferably provided with inlet and outlet tubes, which may be removed.  After drying, a metallic mirror layer or a luminescent layer may be applied to the smooth layer.
