Title: Improvements in the drying of materials
IPC: F26B13/16
Filed: 1936-02-06
Abstract: 470,334. Drying webs &c. BRITISH CELANESE, Ltd., MELLOR, A., and POOL, W. Feb. 6, 1936, No. 3630. [Class 34 (i)] A method of drying, in a plurality of stages, a layer, sheet, or web of material containing a volatile liquid, comprises subjecting the material in at least the first stage to superheated vapour of the liquid so as to vaporize liquid from the material and recovering liquid from the vapour by condensation, and in at least one other stage, including the' final stage, subjecting the material to the action of a gas to complete the removal of the liquid. In the construction shown, fabric 3 unwound from a roll 4, passes to guide rollers 6 rotatably mounted in a trough 7 containing a solution of a dyestuff in a volatile solvent. The fabric passes through rollers 8 of a pad mangle to a chamber 11 in which it travels in the form of a loop 12, afterwards passing over a roller 13 to the drying machine. The chamber 11 is heated by steam pipes 14. The drying machine comprises a chamber 20 which houses a hollow rotatable drum 21 consisting of perforated metal 22 covered with loosely-woven air-permeable fabric 23. The drum is adapted to be driven by rollers 24. Side plates 27 of the drum do not rotate, and are mounted about a stationary hollow cylinder 28. The plates are adjustable towards or from each other in accordance with the width of fabric being dried. The chamber is divided into two compartments 29, 30 by means of a plate 31 within the drum and a lip 32 outside the drum. The compartments are enclosed within casings 33, 34 perforated at 35, 36. A plate 38 is disposed within the cylinder 28, the ends being bent to fit against opposite sides of the cylinder. The -middle portion of the cylinder is of wire gauze 37. Curved shields 40, 44 are provided to form chambers 41, 45, each containing heating pipes, and a fan 49 driven by an electric motor. The fabric 3 on entering the compartment 29 is subjected to suction through the drum and vapour is passed into circulation, the vapour being superheated by the pipes 53. The circulation may be varied by louvre blades 58. Part of the vapour is withdrawn through conduits 59 leading to condensers 60, uncondensed vapour passing back for recirculation. The fabric 3 on passing to the compartment 30 is subjected to the action of warm air. Solventladen air is withdrawn from circulation through a conduit 65, and fresh air is drawn into circulation through an opening 56 in the wall of the chamber 20. Undesirable leakage of air into the drum 21 through the opening 56 in the chamber 20, is prevented by a curved shield 72 fitted to the edge of the plate 31, the shield 72 co-operating with a further shield 73 extending from the lower edge of the opening 56 to a point near the periphery of the drum in registry with the edge of the shield 72. Specifications 469,908 and 470,333, [both in Group IV], are referred to.

IPC: G01L17/00
Filed: 1927-02-11
Abstract: 267,098. Michelin et Cie. March 5, 1926, [Convention date]. Pneumatic-tyre pressure gauges.-Comprises a particular construction of the type in which the movement of a spring piston is transmitted to an indicating needle moving over a circular dial. The chamber 1 is adapted to be connected to a tyre nipple and has located within it a membrane sac 4 of elastic material, clamped so as to provide an air-tight joint between the chamber 1 and a hollow piston 7. Housed within the piston is a spring 8 compressed between the inside of the lower end of the piston and a screwed plug 13 located in a hole in the casing 12. A flange 15 at the upper end of the piston is adapted to engage a lug 16 on a pivoted quadrant 17 gearing with a pinion on a pointer 10. The quadrant is braked by a leaf spring 19 which may be released by a push 21, and the pointer is returned by a spiral spring. This spring is not strong enough to overcome the braking effect of the spring 19. The needle thus remains in any indicating position while the piston is returned by the spring 8 until the membrane meets the abutment 11. The push 21 is actuated to return the pointer to zero.

Abstract: 1,255,503. Moulding artificial conifer branches. DYNAMIT NOBEL A.G. 24 Jan., 1969 [26 Jan., 1968], No. 4281/69. Heading B5A. [Also in Division A4] An artificial conifer branch is made from a preformed thermoplastic structure comprising a wire stem with a plurality of thermoplastic bristles around it, by heating the preformed structure and moving a shaping device defining an aperture of the same shape as the finished structure along the stem while reducing the size of the aperture. The aperture may be initially circular, elliptical or in the form of a slit depending on the desired cross-section of the branch. Reducing the size of the aperture as the shaping device moves along the stem forms the needles to the shape shown in Fig. 1. As shown the apparatus comprises a tunnel 9 in which the performed structure is clamped at 6. Hot air is supplied into the tunnel from blowers 7 so that  the end of the structure adjacent the fans is heated to a higher temperature than the points further along it. The shaping device or devices 5 are moved by chains 2 and comprise two movable aperture defining portions 10 mounted on members 12 which connect with rails 11 not shown. The members 12 move transversely of the tunnel 9 as they move along rails 11 and the space between the aperture defining portions 10 is reduced. This size reduction and the heating of the end of the "branch" to a higher temperature forms it to the shape shown in Fig. 1. In other embodiments, the shaping members may be in the form of a slit, two co-operating wedges or one wedge and a flat member, the resulting branch being flat on each side of the stem.
