Roofing material comprises a layer of bitumen impregnated felt with a woven reinforcement and a layer of insulating material adhered. thereto. The felt may comprise fibrous felt, asbestos felt or fibrous glass tissue. The insulating material may be glass fibre, polyurethane, expanded polystyrene, wood wool slabs or strawboard. To form the roofing material a layer of bitumen felt fed from roll 7 (Fig. 3) is heated by gas jets 12 and passes together with insulating material in the form of separate sheets of expanded polystyrene through the nip of rolls 9 where the layers are pressed together, after which the felt is cut at the joints between the separate sheets either by hand or by an automatic guillotine. If the insulating material is not rigid it may be fed from a roll. The heat may alternatively be an electric or gas radiant heater, or a heated rod or steam pipe. The composite material may be passed between a pair of rolls, one of which carries a number of radially projecting knives so that a series of incisions are formed in the insulating layer, each extending across the width thereof, whereby the composite material can be coiled. Alternatively, the cutting may be done by drawing sharp knives across the sheet or by hot wires before it is joined to the felt.
Patent GB-442083-A (GB)
Abstract: 442,083. Washing granular materials. RICHARDS, H., Ayot, Trelawny Road, Camborne, Cornwall. July 30, 1934, No. 22130. [Class 82 (ii)] Apparatus for extracting concentrates from ores or particular constituents from mineral mixtures, e.g. free values from gold ores or heavy residues from coal, coke, &c., comprises a rotatable framework carrying three or more trays, automatic means for effecting a periodic part rotation of the framework to bring each of the trays in turn into the operative position at a suitable inclination to ensure deposition of the desired constituents on the tray, and automatic means for cutting off the supply of water-flushed minerals just before and during the part rotation. The trays are preferably covered with blanket, corduroy, &c., and they may be hinged to the framework so that they swing away from the frame when it is rotated. In the form shown in Fig. 1 the framework X carries three trays M1, M2, M3, and the material is fed to the tray by a conduit A and launder L. A main water supply B is connected to a branch B3 which supplies water to the launder L, and a branch B4 which allows water to drip into a bucket S1, intergral with the framework X. A branch B1 supplies water to a tipping bucket D which, when full, tips and shuts off the supply of material through the conduit A. The water from the bucket D falls into a tray E1 from which it drips through a tap B5 into a bucket F which tips and withdraws a pawl H from a ratchet wheel G1 on the axis of the framework X. The latter rotates owing to the weight of water in the corner bucket S1. The water from the bucket F pours into an auxiliary bucket F1 which, when full, tips and causes the pawl to re-engage the ratchet, the mechanism being adjusted so that this occurs when the tray M3 has moved into the operative position. When the bucket D tips to shut off the supply of material its place is taken by a bucket D1 which fills from the branch B1 and which tips, after the tray M3 is in position, to re-start the flow of material through the conduit A and to bring the bucket D back into filling position. The concentrates are washed off the tray M1 into a tank P by sprays N1 and N2. Bolt-and-slot mechanism G1 is provided for adjusting the inclination of the trays to the horizontal when in operative position. In the form shown in Fig. 3, the trays are hinged to the framework so that when the latter is rotated they either hang freely or, as shown, strike against stops W2 .. W5, the bumping action helping to dislodge the concentrates. In the form shown in Fig. 5 the direction of rotation is reversed and the trays are formed with hinged end portions Y1, Y2, Y3, which hang freely when the framework rotates. Several of the frames may be arranged in series, the rotation of the first frame which is controlled by means of tipping water boxes as described being communicated to the other frames by driving chains.

Title: Spin dryers
IPC: B04B7/06
Filed: 1973-09-21
Abstract: 1408719 Drying ROBERT THOMAS 21 Sept 1973 [30 Sept 1972] 44334/73 Heading F4G [Also in Division F2] A spin dryer comprises a movable cover 3, an electric switch 24 controlling energization of the drying drum motor a braking device comprising at least one brake band 13, and a safety device which prevents opening of the cover until the drum rotation is stopped. In operation, cover 3 is closed by depression of a tongue 7 and pawl 6 to remove a locking lug 8 from the path of an attachment 9 of a locking member 4. The latter is pivoted through a right-angle to lock the cover 3 and rotates a lever 10, connected thereto, through a shaft 5. Lever 10 engages a brake lever 23, which through a Bowden cable 25 releases brake band 12 and thereafter operates switch 24. To switch off the dryer locking member 4 is pivoted towards its starting position. The switch 24 is released after only a short pivoting movement as lever 23 is rotated by a spring 29 and cable 25. The slackening of cable 25 causes spring 29 to push forward end 28 of band 12 against the drum periphery the band being moved forward by the frictional contact with the drum. End 14 of the band is moved correspondingly, against the action of a spring 17, causing a locking lever 27 to pivot into the path of lever 10 preventing further rotation thereof and opening of the cover. When the drum has come to rest the force of spring 17 overcomes that of spring 29 so that the end 14 is drawn back into its guide 15 and levers 22, 23 pivot back into their initial positions. Lever 10 can then be rotated to allow the cover to be opened.

As shown the radially outer ends of the rollers 16, 17 are supported by bearings 18 pivotally mounted in supports 19 while the inner ends are in contact through respective friction wheels 16a, 17a with discs 5, 6 which are powered by motors (11), (9), Fig.2 (not shown) located beneath the table 1. The disc 6 is located vertically above the disc 5 and hence the rollers 16, 17 have opposite inclinations and hence their support for the inner and outer convolutions respectively. The wound film has its radially inner limit set by rollers 14. The film 13 leaves the centre of the wound film and passes over guide rollers 20, 21 and a roller 22 mounted on pivoted arm 26. A tensioned wire is attached to this and passes around shaft 23 of potentiometer 10 which controls the speed of the motor (9) driving the rollers 17 via disc 6. Hence any undesired variation in the tension of the unwound film 13 is eliminated by an adjustment in the motor speed resulting from movement of the roller 22. Roller 31 in conjunction with shaft 34 of potentiometer 12 controls the speed of the rollers 16 in relation to the tension of the returning film 13. The inclination of the rollers 16, 17 may be adjusted by the raising or lowering of the disc 6 so as to accommodate various film lengths in order that the film is equally supported by the rollers 16, 17.
