Title: Methods for anchoring a flexible sheet of roofing material to  a surface
IPC: D21J1/00
Filed: 1971-04-19
Abstract: 1348917 Coating with preformed sheets SVENSKA ICOPALFABRIKEN AB 19 April 1971 [10 Feb 1970] 20949/71 Heading B6G [Also in Division E1] A flexible sheet of roofing material is anchored to a surface without using any additional supply of anchoring binder, the roofing material comprising a backing impregnated and/or coated with asphalt or bitumen, and a coating of non-tacky material anchored to the backing and consisting of either a continuous layer or spaced apart members, by burning off the coating within limited areas of the roofing material while simultaneously activating the bitumen or asphalt in those areas to render it active as an anchoring binder, and applying the roofing material to the surface so that the activated bitumen or asphalt will anchor the roofing material to the surface. The coating may comprise heat-destroyable foamed plastics bodies which will in any areas of the roofing material from which the coating has not been burned off space the roofing material from the surface to form air gaps. The plastics bodies may be foamed polystyrene or foamed polyethylene. The roofing material may have a single or multi-layer carrier of grey rag boards, jute fabric or glass fibre cloth. It may have a surface coating of crushed stone or gravel or of a metal strip or foil of, e.g. copper. The roofing material may also comprise one or more metal layers, e.g. aluminium, copper or stainless steel which may be embossed or fluted. As shown in Fig. 2 the outermost convolution of a roll of the roofing material is subjected to the action of three burners 12 mounted on a holder 11 and directing their combustion gases or flames against the roll 10. The spotwise heating results in a spotwise destruction of the heat-destroyable bodies so that the roofing material during its continued unrolling and anchoring against the surface will be anchored thereto precisely within these heat-activated areas where the space members have been destroyed. To produce an overlap joint a strip-shaped edge portion extending along one side of the edge of the roofing material can be left free from spacer members as shown in Fig. 3. The entire stripshaped edge portion is heat-activated to provide a tight covering with the air gap-forming roofing material. Preferably this edge portion is covered with a non-tacky plastics foil strip of, e.g. polystyrene, polyethylene or polyester destroyable by melting or burning, the strip being destroyed during heating to provide the desired overlap joint.

Title: Method and apparatus for continuous production of filled and sealed tetrahedral packages of paper or the like
IPC: B65B9/12
Filed: 1945-08-20
Abstract: 597,458. Tetrahedral packages. RAUSING, R. Aug. 20, 1945, Nos. 21249 and 21250. Convention dates, Aug. 17, 1944, and July 25, 1945. [Classes 94 (i) and 94 (ii)] Tetrahedral packages of paper or the like are continuously formed and filled by feeding a web about a former and sealing the longitudinal edges to form a tube which on leaving the former is successively flattened, sealed and cut off at places spaced apart in the longitudinal direction of the tube so that each section of the tube between two such places forms a package which is sealed at its lower end, filled through the former, and then sealed at its upper end, being flattened and sealed alternately in one and the other of two relatively perpendicular planes so as to assume approximately regular tetrahedral form. In one embodiment of the invention, a web 2 is fed over a cylindrical former 3 and its edge sealed by a plate 4. The tube 5 thus formed is fed downwardly by feed rollers, not shown, and is flattened and sealed at places spaced apart alternatively by one or the other of two sets of pressing members, '6, 7. The package 8 so formed is filled through a tube 9 and sealed at its upper end in a plane perpendicular to its lower seal, after which it is severed from the tube 5 by one of two sets of knives, 10, 11. In a modification, one set of pressing members and one set of knives are used, which rotate through 90 degrees between each operation. In a further modification, the web is fed on to the former obliquely so that the longitudinal edges form a helical seam, and the tube so formed rotates around the former through 90 degrees while being axially displaced the depth of one package, so that the flattening and severing operations can be performed by one set each of pressers and knives, both non-rotatable, or by two sets each of pressers and knives acting in perpendicular planesand all rotating with the tube. The former may be cylindrical and flattened from its centre in relatively perpendicular planes towards its opposite ends; the tube is thus flattened before the action of the pressers. This type of former can be used also with a tube having a longitudinal seam. In a further modification, an even number of sets of pressers operating in alternately perpendicular planes may be used, to form two packages simultaneously, the knives being associated with the pressers and adapted to operate automatically at the correct times. The tube may be kept filled with liquid by a pipe or other means to a height above the top of the formed packages, so as to ensure continuous filling thereof.

Abstract: 1420900 Preventing frost heaves in soil; road foundations CHEMIE LINZ AG 15 May 1974 [8 June 1973] 21647/74 Headings E1F and E1G Frost heaves in fine grained soils such as used in foundations of roads is prevented by interrupting the transport of water in the capillaries of the soil in the region of the frost boundary 3 in the soil by inserting in the soil at said region a coarse-pored filter layer 5 which is protected on its upper and lower sides 4, 6 against contamination by particles of said fine soil, by the application to said sides of a permeable, rot proof web of fabric, felt or fleece. The filter layer may comprise loosely introduced grains having interspaces sufficiently large so that water will not be held in the layer by capillary action. The grains may be gravel, slag or particles of plastics material. Alternatively the filter layer may be a solid porous body having pores that permit seepage water to pass vertically the body and in at least one horizontal direction without being hindered by capillary action. The body may be in the form of a mat or plate. The filter layer is preferably constructed with a thickness of at least 10 cms and with a grain diameter of 4 to 50 mm. The fleece may be a fibre fleece of thermoplastics synthetic resin, e.g. a polyolefine or a spun fleece of continuous filaments. The upper fine soil may be laterally sealed off to the entry of water from adjacent soil layers. In such a road foundation the filter layer is sloped down to drains if such drains are provided at the sides of the foundation or the side edges of the layer, if no such drains are provided, are raised up and sealed against entry of surface waters.

Abstract: 1,057,756. Change-speed control. DAVID BROWN TRACTORS LTD. May, 17,1965 [May 27, 1964], No. 21873/64. Heading F2D. A variable ratio transmission for agricultural tractors comprises a first and a second twospeed gear and a three-speed and reverse gear arranged in series, to provide twelve forward speeds and four reverse speeds; both two-speed gears being controlled by a single gear lever with an interlock between their selector rods to ensure that the first gear can only be shifted when a ratio is established in the second gear. The first gear comprises an axially slidable gearwheel 19 having internal clutch teeth engageable with teeth 12 on an input shaft 10 to provide a normal speed, the gear-wheel 19 being engageable with a gear-wheel 17 constantly driven from the input shaft to provide a slow speed. The gear-wheel 19 is shifted by a fork 50 on a selector rod 51 having slots 57, 58 engageable by an end of a gear lever which is biased for engagement with a slot 68 in a selector rod 61 controlling the position of stepped gears 23, 24 of the second two-speed gear. An interlock drift member 69 engages a groove 52 in the selector rod 51 when normal speed is established so that the gears 23, 24 can be shifted to engage gears 31, 32 to give a low and a high range respectively. When the low or the high ratio is established, the interlock member 69 engages a groove 64 or 63 in the selector rod 61 and the slot 68 is aligned with slot 58 or 57 of the selector rod 51 so that the gear lever can be shifted to engage the slot 58 or 57 to enable a shift to slow speed in the first two-speed gear to be made if desired. The three speed and reverse gear is controlled by a second gear lever engageable in slots 78, 88 in selector rods 71, 81 controlling a stepped gear 45, 46 engageable with the gears 31, 32 and controlling a gear 48 engageable with a gear 33 and with a gear 26 for reverse. The selector rods 71, 81 have an interlock member 89 preventing engagement of a ratio unless the other selector rod is in its neutral position. All the selector rods are located in their operative positions by a spring- loaded balls-engaging indents or grooves in the rods. A power take-off shaft 100 may pass coaxially through the input shaft 10 and an intermediate shaft 13, the power take-off shaft either being splined to the input shaft, or the input shaft and power take-off shaft being driven by the engine through coaxial friction clutches.
