Filed: 1957-12-13
Abstract: 863,818. Step-by-step conveyers. GEOFFROY-DELORE S.A. Dec. 13, 1957 [Dec. 15, 1956], No. 38821/57. Class 78 (1). [Also in Group XII] A conveyer, especially for conveying articles through a furnace 8, comprises sets of bars 20, 21 of arcuate form arranged in internesting relationship, means for imparting to the sets of bars separate cyclic motions whereby all the bars in each set are displaced along elliptical paths, the cyclic displacements being 180 degrees out of phase so that articles deposited on the bars are conveyed along them. The ends of each set of bars are connected by cross-members 22, 23 which are themselves connected by pairs of longitudinals 24, 25. Each longitudinal is supported by rollers 26 which are journalled in plates 36 movable vertically between guides provided with rollers 38. Arms projecting downwardly from the plates carry rollers 40, 41 which engage rams 42, 43 mounted on a drive shaft 44. The longitudinals 24, 25 carry downwardly projecting arms 28, 29 provided with rollers 30, 31 which engage cams 32, 33 also mounted on the shaft 44. Each bar 20, 21 has its ends in water tanks 5, 9. Passages 10 lead from the furnace to the tanks and reduce loss of heat. In the wire handling system shown, wire 1 is fed continuously at high speed to a feed-out head 2 which casts it off in successive circular loops 6. The loops are conveyed by spaced parallel belts 3 into the path of the bars 20, 21. After passing through the furnace, the loops are deposited on a conveyer 11, similar to the conveyer 3, and are conveyed between it and a conveyer 14 to a taper casing 16 and a tensioning device 17 and thence to cylinders 18 which are rotated at the same speed as the head 2. Specification 863,817 is referred to.

Abstract: 1445429 Welding by fusion MITSUBISHI JUKOGYO KK 16 Aug 1973 [28 Aug 1972] 38862/73 Heading B3R A butt joint is effected by forming and juxtaposing workpieces 1, 2 so that the weld preparation comprises a parallel-sided groove inclined to the horizontal, applying a backing strip 3, and welding (e.g. CO 2  arc) to fill the groove with weld beads from the back to the front of the groove. The welding is particularly applicable in the horizontal-vertical position shown, e.g. with the groove inclined at 35-60 degrees to the vertical. A strip 4 may be attached to the front of the lower workpiece 2 with the strip upper edge forming a continuation of the lower wall of the groove. The strip 4 is subsequently cut off or may be replaced by a prior-formed bead which need not be removed. The beads may be formed singly or, automatically, in tandem pairs. The groove may be formed by gas cutting. The parallel sides of the groove facilitate relative workpiece positioning by a Spacer. The inclined weld facilitates radiographic inspection (Fig. 8, not shown). In Fig. 9 (not shown), the welding is included in the internal circumferential butt-jointing of 45 degrees inclined penstocks of 3-4 metres diameter.

Title: Improvements in processes and machines for the production of stacks to be expanded into cellular material
IPC: B31D3/02
Filed: 1959-11-18
Abstract: 910,114. Cellular paper. STEMPEL A.G., D. Nov. 18, 1959 [Nov. 19, 1958], No. 39117/59. Class 96. To produce stacked sheet material which can be expanded into cellular form an even number of strips 11, 12 is wound on to a polygonal roller 17, each strip being coated with parallel stripes of adhesive, the stripes on adjacent sheets being relatively offset. When the required number of layers has been built up the mass is severed at the apices as by a knife 32, the polygonal roller being preferably removed from the machine for this operation so that winding can re-commence on an empty roller. The layers are pressed into contact as they are wound by a spring-loaded jockey roller 35. The stripes of adhesive are applied by ribbed rollers 37, with pressure rollers 41, fed with adhesive by rollers 44, 45 dipping in a tank 43 supplied from a container 46. The drive is supplied from a motor 20 to the roller 17 only, through a variable-speed drive 21. As the winding proceeds short lengths of uncoated sheet material may be wound between the superposed layers to define points at which the assembly of layers may subsequently be divided. Slits may be produced in one or more of the sheets, as wound, between theadhesive stripes, by knives controlled by the rotation of the polygonal roller. This assists the production of cellular material with uniform cell size.

Filed: 1929-12-23
Abstract: 336,877. Triggs, W. W., (American Machine & Foundry Co.). Dec. 23, 1929. Variable-speed epicyclic gearing for cigarette-making machines &c. is so arranged that there is no interruption of the drive during speed changes. The driven shaft 11 carries planet wheels 21 meshing with a sun wheel 23 on the driving- shaft 5 and with an annulus 24, which is either held fixed bv a brake band 46 for low speed or connected by a clutch 28 to the shaft 5 for high speed direct drive. The brake and clutch are operated simultaneously, the operating means being connected by a link 57. To prevent backward rotation of the annulus 24 when the brake 46 is released, a spring-operated detent 61, Fig. 4, is brought into engagement with teeth 60 on a ring secured to the annulus and is held in that position until the gear change has been effected. For this purpose a pointed extension 65 of the detent 61 co-operates with a notched block 66 fixed to a sliding bar 54 by which the brake is actuated. Normally the detent is held clear of the teeth 60, but during the movement of the bar 54 the extension 65 passes across the notch and the detent is allowed to operate during the gear change.

Title: Improvements in or relating to the preparation of alicyclic olefinic hydrocarbons
Inventor: WADDAN DHAFIR YUSUF
IPC: C07C13/66
Filed: 1964-10-02
Abstract: A cyclic mono-olefin is obtained from a corresponding cyclic polyolefin (containing all the double bonds in the ring) by forming a Diels-Alder adduct of the latter with a fused polycyclic aromatic hydrocarbon having two meso carbon atoms in a 1,4-relationship to each other, hydrogenating the olefinic bonds in the adduct and decomposing the hydrogenated adduct to recover the aromatic hydrocarbon and a cyclic olefin.  Lists are given of polymers and aromatic hydrocarbons.  The adduct is formed at 125-275 DEG  C. and hydrogenated at 30-150 DEG  C. and 50-5000 p.s.i. in the presence of 2-10% weight of Raney nickel based on adduct and in the presence, if desired, of a solvent such as benzene, toluene or paraffins. The hydrogenated adduct is pyrolysed at 275-450 DEG  C. The examples describe the preparation of the new compounds which are adducts of anthracene with cyclooctadiene-1,5 or cyclododecatriene-1,5,9 and their hydrogenated derivatives and the recovery therefrom of cyclooctene and cyclododecene.

Title: Stereoscopic viewer
IPC: G02B27/22
Filed: 1960-11-23
Abstract: 921,731. Stereoscopic viewers. NEW-MAX S.r.1. Nov. 23, 1960 [Dec. 17, 1959; July 4, 1960; Sept. 17, 1960], No. 40250/60. Class 97 (1). A stereoscopic viewer comprises a box-shaped frame containing a translucent wall, a film track in said box-shaped frame, two eyepieces, the axes of which are spaced from one another by a distance substantially equal to the average spacing of a pair of human eyes, the film track having two windows spaced from one another substantially as the above-mentioned eye-pieces, and at least one intermittent film feed device which includes a stop tooth fixed to the frame and co-operating with perforations provided in the film so as to cause alignment of any steroscopic pair of picture frames on the film with the said windows and means for successively disengaging the perforations from the stop and effecting instantaneous displacement of the film from one picture pair to the next successive picture pair to obtain cinematographic viewing. As shown, a stereoscopic viewer comprises a housing 1 providing a track 4 for film 5 and having two eye-pieces 2-3 for viewing steroscopically related pairs of images by way of light admitted through windows 8. In the case of film having pairs of images arranged in laterally adjacent rows as in Fig. 12, deflecting prisms 80 are provided in the eye-pieces 2, 3. The eye-piece lenses g may be eccentrically mounted in a rotatable mount 41 (Fig. 7, not shown) to compensate for differences in individual inter-pupillary distances. The film may be in loop form (as in Fig. 1) or in the form of a strip accommodated on spools. At least one row of perforations are provided. The intermittent film feed device operates as follows. By means of a winding crank 13 coupled to a sprocket wheel 11 (Figs. 1 and 4) the tension in the film between members 10 and 13 is increased thereby bending a leaf spring 23, about its pivot 22, said spring having a stiff limb 23b engaging the film and a relatively elastic limb 23a bearing against a fixed surface 1b. Eventually the film disengages one of its perforations from a tooth 10, and under tension of spring 23, is advanced until the tooth 10 engages the next perforation. This process is repeated. In modifications the spring 23 is replaced by a lever urged to rotate magnetically. The tooth is provided with one inclined face to facilitate rewinding of the film. Two such intermittent feed devices may be provided-one for each direction of feed-as in Figs. 10 and 11 (not shown).
