Patent GB-487648-A (GB)
Title: Improvements in the manufacture of fibres from glass and other materials
IPC: D04H1/00
Filed: 1937-10-21
Abstract: <PICT:0487648/IV/1> In the production of fibres by subjecting thin streams of molten material to the action of a blast of gas or steam directed in substantially the same direction as the streams, the blast is given a turbulent character so that it acts differently on different portions of the same stream and so attenuates the stream and tangles the fibres to make a mat of very fine fibres.  The fibres may be drawn out by this means until they break so that staple lengths are produced.  Preferably, the steam continues to expand gradually after it leaves the blowing nozzle.  The invention is described with reference to the production of glass wool.  The blower nozzle 19 is formed with separate jets which are arranged at distances such that a large portion of the surrounding atmosphere is drawn into the blast.  Lubricants or binders may be sprayed from a nozzle at 27.  A list of substances with which the invention can be employed, including resins, is given in the Specification. Specification 428,720, [Group XXIII], is referred to.

Title: Device for removing air and/or foam from oil
IPC: B04B5/00
Filed: 1977-07-08
Abstract: 1529650 Centrifugal separators KLOCKNER-HUMBOLDT-DEUTZ AG 8 July 1977 [16 July 1976] 28757/77 Heading B2P A separator for removing air and/or foam from oil comprises a centrifugal chamber 1 rotatable about a vertical axis and having an aperture 4 at its top, blades 7 disposed within the chamber 1 adjacent the top aperture 4 and means 8, 9 to direct under pressure oil to be treated onto the blades 7 to drive the blades so that the centrifugal chamber 1 which is connected directly or, as shown, indirectly to the blades is driven in rotation, the chamber 1 having outlet means for the flow of treated oil from the inner surface of an outer wall of the chamber. The blades 7 are carried by the upper region of an upwardly tapering frusto-conical jacket 5 secured by feet 6 to the base wall of the chamber 1. A disc 10 of wire gauze is mounted across the jacket 5 to improve foam removal or retain stable foam. A collecting cup 11 for treated oil is disposed around the chamber 1. In operation, the oil flows downwardly through the disc 10 towards flow apertures in the base wall of the jacket 5 and then flows outwardly along the base wall of the chamber 1 and upwardly along the chamber cylindrical wall and out of the aperture 4 where it strikes a sloping wall 12 of the collecting cup 11 so that foaming of oil as it enters the cup is prevented. Air and/or foam separated from the oil leaves through the apertures at the top of the jacket 5, the chamber 1 and the cup 11. In a modification, a number of concentric frustoconical jackets are disposed in the chamber 1, the blades being carried by the innermost jacket and the oil flowing from jacket to jacket as it passes towards the chamber 1.

[Class 102 (i)] In a pump having a pumping chamber 38, the volume of which is increased and decreased alternately by the piston or driving means 14, and which has inlet valves 40 and delivery valves 51, the delivery being restricted when the outlet pressure exceeds a predetermined value, the pump also comprising a delivery chamber 66 with a spring-urged movable wall 58 carrying the delivery valve which normally isolates the delivery from the pumping chamber but which, when the pressure in the delivery chamber exceeds a predetermined value, together with the movable wall is pressed back, as described in the parent Specification, the piston 14, towards the end of its stroke, mechanically engages the delivery valve 51 to open it positively. The end wall of the piston 14 opens on to the inlet valve 40 the stem 44 of which is slidable in the wall and the margin 47 of which seats on the wall. A central recess 18 in the inlet valve is adapted to receive a stud 80, which secures the delivery valve 51 to the movable wall 58, when the piston 14 approaches its outermost point, a resilient covering 78 absorbing the shock of impact.

Title: Improvements relating to wire wound potentiometers and variable resistors
IPC: H01C10/20
Filed: 1951-12-07
Abstract: 721,952. Variable resistors. COLLINSON, R. F. March 9, 1953 [Dec. 7, 1951], No. 28779/51. Class 37. In a wire-wound potentiometer using a single control member fine adjustment occurs when a first slider takes up lost-motion and moves over an axuillary resistance element and coarse adjustment occurs when the first slider drives a second slider over the main resistance element. In the rotary potentiometer shown an auxiliary resistance segment 22 bridges contact fingers 20, 21 which, one in advance of the other, ride along the main resistance toroid 11. If coarse and fine adjustment are successively required the control spindle 25 sweeps contact finger 30 along resistance segment 22 and finger 30 engages stop 23 or 24 and then drives contact fingers 20, 21 along toroid 11 to give the required coarse adjustment and this is followed by reverse rotation of spindle 25 so that contact finger 30 is shifted along segment 22 until the required fine adjustment is attained. The resistance segment 22 is located in a recess in cylindrical insulating rotor 14 which carries spring arms 18, 19 terminating in the contact fingers 20, 21 and connected to the segment 22 via stops 23, 24. The spindle 25 supports by nut 26 and key member 27 a disc 28 so that the latter may be rotated with respect to rotor 14. The disc 28 carries a contact ring 29 which has on one side the contact finger 30 and diametrically opposite this finger 30 there is a second contact finger 31 engaging a current collector ring 15 encircling the rotor 14. With movement. of rotor 14 during coarse adjustment the current collector ring 15 rides against a stationary springy contactor 16. In a modification the contact ring 29 is replaced by a U-shaped member having a contact finger (similar to 30) for travel along resistance segment 22 and a pair of contacts like 20, 21 for travel along a contact segment fixed diametrically opposite the re- . sistance segment 22 and connected to current collector ring 15. If desired as an emergency or permanent alternative to stops 23, 24 which are in reality metal links the insulating rotor may have pins 32, 33 for co-operation with contact finger 31.

Abstract: 1365986 Sealing packages IMPERIAL CHEMICAL INDUSTRIES Ltd 6 June 1973 [22 June 1972] 29332/72 Heading B8C [Also in Division B5] A method of sealing a folded sealable wrapper about a packet 1 comprises conveying a wrapped packet past a member 11 positioned to retain the folded wrapper in position on the packet, maintaining between the packet 1 and the retaining member 11, a movable surface, advancing the surface solely by engagement with the packet relative to the retaining member in the direction of motion of and at substantially the same speed as the packet, and supplying sufficient energy to the area of wrapper in contact with the moving surface to seal the wrapper in that area. As shown a series of packets 1 each wrapped in a vinylidene chloride/ acrylonitrile copolymer coated polypropylene film is fed in a packet-pushing pocket sequence along a base-plate 2 between side walls 3 which retain in position folded end flaps 4 of the wrappers. The packets are fed between a pair of polyethylene terephthalate endless belts 5 within each of which is positioned a retaining member 11 provided with internal electric heaters and temperature sensors (not shown). The surface of each member 11 in contact with the belt is coated with polytetrafluoroethylene to reduce frictional drag between the belt and the member 11, the arrangement being such that as each wrapped packet passes between the members 11 the flaps 4 are heat sealed. The belts themselves may be heated to effect heat sealing and may also be used to transfer matter such as labels to the sealed areas of the packet. Sealing may be effected by other than heat, e.g. by ultrasonic bonding techniques or the end flaps may be coated with pressure-sensitive adhesive, cold adhesive, hot-melt adhesive or heat sealable polymeric adhesives.
