Title: Improvements in machines for finishing silk fabrics
IPC: D06B3/10
Filed: 1919-08-27
Abstract: 149,842. Vuono, G. P. Aug. 27, 1919. Coating fabrics in long lengths. -In a machine for applying finishing paste to silk fabrics, of the kind in which an applying-roller with a resilient surface transfers the paste directly from a trough to one side of the silk which is pressed against the applying roller by a vieldinglymounted impression roller, and in which a regulating-roller cooperates with the applying-roller to determine the amount of paste so transferred, the regulating- roller is of hard material and is mounted in adjustable non-yielding bearings so that it may be adjusted to deform the rubber or other resilient covering of the applying-roller to a definite extent and control very exactly the amount of paste applied to the silk. The applying-roller 16 is driven at adjustable speed from the power shaft 2 by means of a friction disk 7, adjustable friction wheel 8, shaft 9, and devel-pinions 12, 13, and the impression roller 33 and paste-regulating roller 17 are driven by pinions on their shafts 34, 18, meshing with a pinion on the shaft 14 of the roller 16. The shaft 18 of the roller 17 is journaled in blocks 21 carried on the lower ends of a pair of pivoted arms 22, and is adjustable towards the applying-roller 16 by means of a pair of screws 26, which thread into the blocks 21 and are actuated by a hand-wheel 32 and geared pinions 30. A pointer on one of the blocks 21 cooperates with a scale on the machine frame to indicate the degree of deformation of the resilient roller. The shaft 34 of the impression roller 33 is mounted in a pair of arms 35 pivoted on a shaft 23, and the silk fabric in its passage through the machine passes over a guide roller 38 mounted on a shaft 36 connecting the free ends of the arms 35 so that the tension of the fabric round the guide roller 38 forces the impression roller 33 against the applying-roller. Cams 40 on the shaft 36 enable the impression roller to be raised clear for threading in the fabric before starting the machine. In the modification shown in Fig. 11, the regulating-roller is duplicated, one roller 59 being of hard rubber and the other roller 60 being of soft rubber. Each roller is geared to the applying-roller 16, and is mounted in a pair of arms 65 pivoted at 66 and adapted to be rocked by eccentrics 68, the deformation of the resilient surface of the applying-roller being indicated by pointers 71 and scales 72.

Title: A method of and means for solidifying films of liquid materials
Inventor: REAVELL JAMES ARTHUR
IPC: F26B3/30
Filed: 1949-08-16
Abstract: Solutions of heat-sensitive solids are evaporated to dryness by spreading the solution as a film upon a continuously moving surface made of glass, quartz, a fabric impregnated with a silicone resin, or made of any other material having a poor heat-conducting characteristic whilst being permeable to infra-red radiation, and impinging infra-red radiation directly on the film and/or passing infra-red radiation through the moving surface.  A rise in temperature of the moving surface <PICT:0682675/III/1> <PICT:0682675/III/2> is substantially obviated, and consequently no heat is transmitted to the film by conduction.  The production of solid gelatine and agar-agar, is ferred to.  The invention may also be applied to obtain synthetic plastics and other materials which are produced by solidification of liquid mixtures by chemical change effected by heat.  In Fig. 3, the external surface of a rotating drum is sprayed with liquid from arcuate plate 18 which is fed through pipe 19, and the internal surface is coated with liquid from the lip of trough 21 which is fed through pipes 22.  Both films of liquid are irradiated by infra-red generators 4 and 6.  The solidified material is removed from the external surface of the drum by brush 20, and collected on belt conveyer 26, while the solid is removed from the internal surface by brush 23, collected in trough 24, and discharged from the drum on to belt conveyer 27 by means of conveyer screw 25. In Fig. 5, the upper horizontal stretch of belt 33, which is made of woven glass or asbestos fibre impregnated with a silicone resin and is driven by rotating drums 34, passes between infra-red generators 36 and 38.  The upper surface of the belt is coated with a film of liquid from trough 8. The solid is removed from the belt either by brush 20 or by suction duct 40.  The apparatus may be enclosed within a chamber 52 which is evacuated through conduit 53.  An embodiment is also described wherein both the outer and the inner surfaces of a travelling belt are coated with films of liquid.  The infra-red generators may be tungsten or carbon filaments, electrically-heated platinum or other resistance wires wound on ceramic tubes, or steel or silica vessels through which hot fused salts, oil, or mercury vapour, is passed.

Title: Improvements in motion checking devices
IPC: B62D7/22
Filed: 1939-07-25
Abstract: 534,018. Fluid-friction motion dampers. NEWHART, H. D. July 25, 1939, No. 21541. Convention date, Oct. 8, 1938. [Class 108 (iii)] [Also in Group XXXI] A vibration-damper, particularly for automobiles, comprises a vaned oscillatory piston 22 mounted on a shaft 33 journalled in a casing 11 fixed to a stationary member. Each vane spreads out at the end into an arc 23 which bears against a resilient diaphragm 27 forming a chord, so that for a small arc of movement about its medial position the piston vanes divide the casing 11 into four compartments 29. The compartments 29 are interconnected by restricted passageways through which the liquid has to flow while the vane ends are in contact with the diaphragms 27, thus impeding rapid motion of the piston, but when the vane ends have passed from contact with the diaphragms, rotary motion of the piston is free. Journal blocks 18 form one wall of each compartment 29, and have passages 54 leading from a recess 52 to the compartments 29 to admit liquid from an upper reservoir to pass through clack valves to the compartments 29 to relieve any vacuum that may tend to form. The shaft 33 fits loosely in a hub in the upper reservoir and allows the fluid from compartments 29 to squeeze by and through openings reach the upper reservoir to relieve excessive pressure in the compartments 29. The passageways connecting the compartments 29 reach into a common cylindrical recess 30, Fig. 6, in which slides a valve sleeve 38 to adjust the opening of the passageway ports 37. The adjustment is both a primary one, obtained by screwing the sleeve rod 39 up or down the shaft 33 and locking it by a nut 41, and a secondary one which automatically restricts the ports 37 with increase of temperature, to compensate for increased fluidity of the liquid at higher temperatures. This device comprises a plurality of bimetallic discs 44 built up of, say, brass and of the metal sold under the Registered Trade Mark " Invar," located below a ridge 43 within the sleeve, and held by a spring 48 bearing against the ridge and a shoulder 42 on the sleeve rod 39. With increase of temperature the sleeve 38 is moved bodily up its rod 39. The shaft 33 is connected to an arm 16 which may be linked to the steering mechanism and have the two steering rod ends bearing on a medial point, or the end of the arm 16 may be pivoted to a cushioned link 64, Fig. 8, bearing on the road wheel 63. The steering mechanism in this case communicates the damping action to the other road wheel.

[A Specification was laid open to inspection under Sect. 91 of the Acts, Jan. 25, 1935.] [Class 139] In a clock driven by an electric motor, e.g. a synchronous motor, the time is indicated by a movable index which reads against a stationary hour scale, and a moving minutes scale. As applied to a geographical clock, a globe 67 is rotated in the direction of arrow t<1> intwentyfour hours and the time at any meridian is read off on the fixed hour scale 70, (two series of twelve hours each), and the concentric minutes scale 71 (two series of sixty minutes each) which rotates in the opposite sense to the globe at <11>/24 revolutions per hour. The globe rests on a plate 68 frictionally resting on a plate 79 rigid with a sleeve T<2> concentric with a fixed sleeve T<1> and mounted thereon by adjustable ball bearings 85, 88, and is driven through gearing 75, 78 from a sleeve 73. The minute scale 71 is carried by arms 80 fixed to a sleeve 82 which rests on and is frictionally driven by a ring 83 rigid with a sleeve T<3> rotatably mounted by means of adjustable ball bearings on sleeve T<2> and driven through gearing 74, 81 from a shaft 72. The shaft 72 and sleeve 73 are driven at appropriate speeds by a synchronous motor (not shown), and the friction drive to the globe and minute scale permits of setting to correct time. The globe is made of glass or other translucent material and illuminated internally by an electric lamp the leads 76 for which pass through the sleeve T<1>. A particular meridian, e.g. 69 may be rendered more prominent than the remaining meridians. The Specification as open to inspection under Sect. 91 also states that a screen may be provided inside the globe to illuminate the part thereof corresponding to night time. Fig. 5 (Cancelled) shows a cylinder carrying a planispheric map the driving and time indicating devices of which are stated to be similar to those described above. This subject-matter does not appear in the Specification as accepted.
