Abstract: 1,242,471. Blowing bitumen. OSTERREICHISCHE MINERALOLVERWALTUNG A.G. 17 July, 1969 [25 July, 1968], No. 36039/69. Heading C5E. In a bitumen-blasting process water is introduced into an air stream and is evaporated by heat from the bitumen, through which the resulting air and steam mixture is passed. The water is supplied to the top of each of a plurality of vertical tubes depending from an air manifold into the reactor, for indirect heating by the bitumen in the reactor. The air-steam mixture is delivered by each tube to the base of the reactor and passes upwards by a deflector and a turbine for dispersing bubbles of the mixture into the bitumen.

Title: Method and apparatus for curing elongated articles
IPC: B29D29/00
Filed: 1972-08-02
Abstract: 1393936 Curing elongated articles DUNLOP Ltd 30 July 1973 [2 Aug 1972] 36074/72 Heading B5A An elongated article 4 is cured by engaging successive portions of the article by two series of platens 3a, 3b staggered in the longitudinal direction of the article, securing the staggered platens together to prevent displacement of the platens longitudinally, moving the article and the platens in stepwise manner longitudinally while curing the article, and applying compressive forces to the article via the platens while the article and platens are stationary between stepwise movements. The invention is applied to the continuous curing of reinforced conveyer belting described in Specifications 1,213,006 and 1,175,521. After compression of the article by pressure plates 30, 31 and while still compressed by press head 28 opposite ends of upper platens 3a are secured to the centres of successive lower platens 3b using clamp plates 101 hinged to the upper platens at 102. The clamp plates 101 are bolted to an inclined surface of a lower platen 3b. The platens may be prevented from separating longitudinally and transversely by other clamping devices (not shown) viz a hook (130, Fig. 13) mounted on an eccentric (131) on the lower platen is drawn on to a spindle (133) on the upper platen by rotation of the eccentric ; a bar (120, Figs. 11 and 12) passing through shoulders of upper and lower platens is attached via a spring (122) to the upper platen and locked to the lower platen by a wedge 124 engaging between the platen shoulder and a projection on the bar (120); an arm (110) pivoted to the upper platen and carrying a block engaging a cam surface (114) on the lower platen.

Title: Improved method of and machine for making cigar fillers
IPC: A24C1/02
Filed: 1932-12-22
Abstract: 396,607. Cigar - making machines. KJAER, J. W., 1A, Morlenesvej, Holte, Denmark. Dec. 22, 1932, No. 36296. Convention date, Dec. 23, 1931. [Class 130.] Cigar fillers are formed from a strip of superposed compressed tobacco leaves of a width equal to the length of the filler and having the leaf stalks extending transversely of the strip, by cutting the strip transversely into pieces corresponding to the size of filler desired. The cigar may then be completed in the manner described in Specification 382,207. Fig. 1 shows the table 11 of the machine described in the above-mentioned Specification provided with a container 34 of rectangular cross-section, in which are placed superposed blocks of compressed leaves. The container is open at the bottom and the blocks of leaves rest on an endless band 35 arranged a short distance below, so that as the container is reciprocated to and fro along longitudinal guides 32, slabs of leaves are cut off by a pair of rotating knives 45, 46, the stalks of the leaves being transverse to the direction of motion of the slabs. These slabs are carried forward in succession so as to form a continuous strip, by another endless band 50, under a grid 51, and then under a third endless band 52, to a rotating cutter provided with radial knives 54, against which the strip is pressed by a roller 65 and cut transversely into fillers. The fillers are carried round between the knives 54, and when at the bottom are ejected by plungers 55 moved between the knives by a cam 60, each filler falling into a wrapper 20 arranged over a space 19 as described in the abovementioned Specification. The ejected filler is first received by a pair of pivoted members 70, Fig. 3, on a slide 68 which is reciprocated in vertical guides 67 by a cam-actuated lever 74. When the slide 68 is in the upper position shown, the members 70 are inclined to receive the filler, but when the slide reaches its lower position, the members 70 are moved parallel to one another by guides 72 and deposit the filler on the wrapper 20. The filler and wrapper are then pressed down into the space 19 by a plunger 82 which is given a right-angled movement corresponding to the shape of a guide 85, in which a block 84 connected to the plunger 82 is moved by a cam-actuated lever 87. Premature falling of the filler from the rotating cutter 54 is prevented by a stop 92 which normally closes the space between the lowest pair of knives 54, but is pushed to one side against spring action, as shown in Fig. 3, by a pin 95 on the slide 68 when this reaches its upper position. Complete severance of each filler portion from the next succeeding one is ensured by a spring-mounted knife 100, which is moved closely past each knife 54 as it passes, by means of a lever 98 actuated by cams 97 on the roller 65. The knives 54 may be plane or curved, according to the shape of filler desired.

Abstract: 898,084. Seaming non-metallic sheet material. MESSERSCHMITT A.G. Nov. 18, 1958, No. 36428/61. Divided out of 898,082. Class 42(1). A method of forming a twothread seam consisting of an upper and a lower thread, is characterized in that the two threads are connected together at successive intervals by means of a thermoplastic resin material applied thereto, the material being applied to the thread at least partly within the body of the fabric. In the arrangement shown balls of thermoplastic material are pressed into the fabrics 15, 16 by pins 2 and 11 taking threads 28 and 29 with them. The balls are softened by heating e.g. by high-frequency electric current so as to connect the threads together. The process is repeated in conjunction with stepwise feeding of the fabrics to form a seam. In another embodiment a continuous wire of thermoplastic material is used and small plugs are cut from the wire and pressed into the fabrics. The fabrics may or may not be preformed with holes to receive the thermoplastic material.
