Title: Improvements in or relating to curtain cornices and to methods of bending the same
IPC: A47H2/00
Filed: 1958-12-15
Abstract: 849,517. Making curtain cornices; angular bending. KARLSSON, N. G. Dec. 15, 1958 [Dec. 16, 1957], No. 40293/58. Classes 83 (2) and 83 (4). [Also in Group XIV] A method of bending a curtain cornice consisting of a metal girder comprising a plurality of suspension rails 1, 2, for carrying the curtain, at least one covering flange 4 serving to conceal the suspension rails and means for carrying the curtain, and a web 3 integrally connecting the flange and the rails, comprises the steps of cutting through said web and said suspension rails at an angle corresponding to the angle of the intended bend, cutting out said web, adjacent to said covering flange, a piece of material having a straight edge or surface of detachment 5 towards said covering flange and curved surfaces of detachment 6, 7 towards said suspension rails, bending said profiled girder to the desired angle, and fixing the cut parts of said web and said suspension rails respectively relative to each other. Cut edges 8 of the web 3 are held together by a fitting 9 riveted, glued or welded to the web. Tongues on one cut face of the web or rails may be formed to co-operate with recesses on the other cut face. The girder may be bent in the opposite direction in which case a filler piece is fitted in the corner. Gaps 11, Fig. 5, may be cut in the rails 1, 2 adjacent the bend, the gaps being overlapped by plastic stoppers 12. A layer of veneer or metal or plastic, may be glued to the front side of the flange 4, or may be held thereon by tracks 15, Fig. 7. A plastic section 14, Fig. 8, may be fitted over the flange 4. Projections on the veneer or plastic section may fit in holes in the flange 4. The coating for the flange 4 may be in three parts, Fig. 9, two end parts 17 being riveted to the flange over the bends and an intermediate part 18 glued to the flange 4 and to the end parts 17.

Abstract: 1283406 Acylation of cardenolides and butadienolides ARZNEIMITTELWERK DRESDEN VEB 14 Aug 1969 40700/69 Heading C2U The selective acylation of steroids of Formula I infra which contain at least three hydroxyl groups, two of which comprise a cis-1,2- or cis- 1,3-diol grouping, is achieved by converting the diol grouping into a grouping of Formula II, III, IV or V (wherein R 10  is H, OH, alkyl or aryl, R 11  and R 12  are each aryl and R 13  is OH, alkyl or aryl) whereafter the remaining free hydroxyl groups(s) is(are) partly or wholly acylated and the cyclic boron- or arsenic-containing group is cleaved to regenerate the diol grouping. The starting materials are of general formula wherein R 1 , R 2 , R 4 , R 5 , R 6  and R 9  are each H or OH, R 3  is CH 3 , CHO or CH 2 OH, R 7  is H or 1 to 4 linked sugar residues, and R 8  is a butenolide or pentadienolide ring. Specified reactants for protecting the diol grouping (which may be in the steroid moiety and/or in any sugar moiety) are boric, metaboric, phenylboric and diphenylboric acids and anhydrides thereof, arsenic trioxide and arsenic pentoxide. Specified acylating agents are acetic anhydride and phenyl isocyanate yielding acetates and phenylcarbamates respectively. Cleavage of cyclic boron-containing groups is effected with water, alcohols, dilute alkalis, adsorbents or basic ion-exchangers, and cleavage of cyclic arsenic-containing groups is effected with water, hydrogen sulphide or chromatography.

Title: Improvements in method of operating a circular knitting machine
IPC: D04B9/46
Filed: 1965-09-28
Abstract: 1,111,742. Knitting. TEXTILE MACHINE WORKS. 28 Sept., 1965 [7 Oct., 1964], No. 41205/65 Heading D1C. In a four feed circular machine where auxiliary feeds become inoperative before reciprocation, certain needles of selected special groups tuck, thereby avoiding eyelet formation. Yarn withdrawal. When the yarns are to be withdrawn before knitting the heel, the stitch cam at auxiliary feed 17 is partially withdrawn so as to miss the short butt needles of the group 78 associated with the next auxiliary feed 18. The short butt needle pass through the station at tuck height taking, but not knitting the yarn, whilst the remaining needles in the group take and knit the yarn. As the group approaches its feed 18 a selector lever 82 is activated to act on jack butts at a first level 85 to prevent them engaging the clearing cam 55. A second lever 80 acts on butts at a second level 81 to prevent raising of the group during reciprocation. At feed 18 the short butt needles knit the fed yarn and the previous yarn together, whilst the remaining needles tuck a stitch of the fed yarn with the previous yarn. As the other feeds are activated the lower part 27 of the main stitch cam is withdrawn to miss the short butts of the other special groups of needles 77, 76. The groups are selected by jack butt levers (at levels 95, 85 Fig. 4 not shown) to ensure that the groups approach the auxiliary feeds 16, 17 at tuck height. Levers 80 again act on butts at the second level to prevent raising during reciprocation. The yarns are similarly withdrawn before knitting the toe. Yarn Introduction. When the auxiliary yarns are to be introduced after knitting makeup courses or the heel, the lower part 27 of the main stitch cam is partially retracted to miss the short butt needles of each group. As the first group 78 approaches auxiliary station 16, a selector lever 65 (at level 95 Fig. 4) tilts the jacks away from the raising cam 55. The needles approach the auxiliary cam at tuck height and knit tuck stitches as at yarn withdrawal. Needles following the group are raised to knit by the raising cam. The special groups approaching the other auxiliary feeds are similarly selected, and the feeds are activated simultaneously.

In an EGD system for the generation of electricity, ionization of a vapour occurs in a low-pressure zone of a duct downstream. of a nozzle and the ionized vapour is conveyed to a downstream electrode. The walls of the duct are shaped so that the envelope of the ionized fluid does not touch the walls except at the edge of the collector electrode. Steam is produced in a boiler (1), Fig. 1 (not shown), and flows through a nozzle (3) into a duct (4) which is provided-at its downstream end with an ionizing electrode (7) and collector electrode 5. Ionizing electrode (7) comprises a tube 19 enclosing a rod 21 connected to a source of high voltage and terminating in a corona electrode 22, 23 which is shielded from the gas flow by cowl 8. Dry steam is fed through a valve to the tube 19 and is ionized as it passes through slots 20 to mix with the main steam flow in the duct. The ionized mass E which does not touch the walls then passes to collector electrode 5 to produce a potential difference between electrode 5 and electrode (7).
