Title: A duct wall of an mhd generator
IPC: H02K44/12
Filed: 1966-03-02
Abstract: 1,115,394. Generators operating by electromagnetic interaction with fluids. COMPAGNIE GENERALE D'ELECTRICITE. 2 March, 1966 [2 March, 1965; 27 Dec., 1965; 28 Jan., 1966], No. 9236/66. Heading H2A. [Also in Division B3] The duct wall of an MHD generator comprises a mosaic of prism-shaped metal elements 1 with one end 5 defining the gas channel and separated at this end by refractory material 4 wherein two spaced apart layers of elastomeric silicone 2, 3, having a Shore hardness coefficient between 40 and 90 secure the elements in a substantially fixed position and provide, in the space between the layers, coolant channels 6 which are of rectangular shape. Manifolds 12<SP>1</SP>, 13<SP>1</SP> for the coolant are provided at the sides of the wall and the whole assembly secured in a metallic box 9, 10, 11. In a modification, the other end of the metal element may be slotted to provide, when aligned in the assembly, the required coolant ducts, Figs. 4-6 (not shown). In a further modification a number of metal elements are joined together at their vertical corners and assembled in overlapping relationship so that slots in the elements provide the coolant channels, Figs. 7 and 8 (not shown). The refractory layer 4 may comprise a number of superposed layers, each having different densities and with the layer adjacent the gas channel having a high thermal conductivity. The inner layer may be porous and sealed with resin which burns away at the operational temperature of the duct, alternatively the inner layer may be provided by a gas space, Figs. 9- 11 (not shown). The refractory material may be applied as preformed sections fitted between the elements and the latter may be " necked " to provide additional security. The wall is constructed by mounting the metallic elements, after preparation of the surfaces to which the elastomeric silicon adheres, upside down on a plate and securing them together by pouring a fusible alloy into the spaces between the elements and a frame. The plate is removed and holes drilled through the fusible alloy, and the assembly mounted together with the manifolds and suitable neoprene masking elements in a vacuum impregnation apparatus for introducing the elastomeric silicone into the assembly. The masking elements and frame are removed after polymerization since this heat treatment also melts the fusible alloy. The completed assembly is placed in the metallic box and the refractory materials inserted to complete the wall structure. Reference has been directed by the Comptroller to Specifications 1,031,921 and 968,221.

Title: Improvements in or relating to multiple tariff counting mechanism for measuring instruments
IPC: G01R11/56
Filed: 1943-06-10
Abstract: 569,075. Supply meters. LANDIS & GYR SOC. ANON. June 10, 1943, No. 9317. Convention date, July 7, 1942. [Class 37] Multiple tariff counting mechanism for measuring instruments is characterised in that a bimetallic strip wound in the form of a helix which is located within and is indirectly heated by a tubular resistance arranged in a circuit connected to the mains, acts through linkwork upon sets of gearing constituting the transmission means of the tariff mechanism, to effect change-over of the said tariff mechanism. A bimetallic helix 24 heated by a tubular resistance 25 energized from mains 26 under the control of a time switch 27, tilts a bellcrank lever 18, 19 fixed on a spindle 15 to cause either pawl 16 or pawl 17 to lock wheel 7 or 14 so as to determine which of two counting mechanisms 1, 3 or 2, 4 is driven by the meter driving wheel 11 through differential gearing 8, 12, 13. A flap 22 moved relative to an aperture indicates which counter is, at the moment, in use. A second bimetallic helix 28 operatively connected to spindle 15 serves to compensate for ambient temperature variations. This compensation may be incorporated in the main helix 24.

Title: Improvements in full fashioned knitting machines
IPC: D04B11/00
Filed: 1939-03-24
Abstract: 526,835. Knitting - machines.., DEHN, F. B. (Textile Machine Works). March 24, 1939, No. 9335. [Class 74 (ii)] Relates to straight-bar knitting machines adapted to make both the leg and the foot portions of stockings. An arrangement is provided whereby an existing standard legger knitting-machine may be converted to perform also footer operations under commercial conditions and with only minor changes in the mechanism. The legger, which it is desired to convert comprises essentially banks of needles 22 which receive knitting motions from cams on a main cam shaft 23. For narrowing the fabric, each needle bank has associated therewith a pair of wide combs 25 and a pair of narrow combs 26. There is also a lock-stitch bar 27 for making picot edges &c. The dimensions of the needle bank 22, bar 27 and combs are such as to cause the bar and combs always to overlay each other longitudinally of the machine. The lock-stitch bar is mounted to dip with the narrowing bar 28 and is held at a rest position above the combs 25, 26 as shown in Fig. 1. When the lock-stitch bar is to be used the narrowing bar is raised, the combs being raised therewith to such a height that when the narrowing bar is next dipped the combs will not reach the fabric, and the lockstitch bar is lowered to the position shown in Fig. 8. The bar 27 reaches to a point below the combs, and when the bar 28 is next dipped the bar 27 will engage the fabric. The points of the combs are received in recesses 53, 54 in the bar 27. The narrowing bar 28, mounted on pivoted links 31, carries a bracket 34 in which slide narrowing rods 33 and in which is journalled a shaft 35 to which are fixed, by arms 36, the lockstitch bar 27. The bar 28 is dipped by means of levers 42, 43, 68, the lever 68 having a cam follower 70 engaging during straight knitting an idler cam 66 and during transfer knitting a dipping cam 67. When the bar 27 is to be used a hand lever 48 is pulled to raise a strut 45 engaging the nose of lever 43 and raises a nose 72 on this lever from its position of rest on the lever 68 to a position above the lever' 68. A bolt 74, slidably mounted on the lever 68, is now moved manually under the nose 72 and supports the levers 43, 42 and the bar 28 with its combs and lock-stitch bar in their new position. (Movement of the bolt also operates, by means not shown, to move axially a shaft 80 and thus release the end of a lever 77 pivoted at 78 ; this lever which normally locks the bar 27 in the raised position of Fig. 2 may now be turned clockwise by the push of part of the bar 27 as the latter swings downward). The lock-stitch bar shaft 35 is now turned manually by means of a handle and the bar 27 thus swung down; at the end of its down-swinging movement the bar is locked in position by a spring 65 which forces the shaft to the right as a bolt 63 rides on to a cam 62, and snaps a locking lug 57, fixed on the shaft 35, into engagement with a keeper 55.

Title: Processes for the production of 11ª--hydroxy-steroids
IPC: C12P33/00
Filed: 1959-03-19
Abstract: 11a -Hydroxy-steroids of the general formula <FORM:0896913/IV (b)/1> and the corresponding compounds having in addition unsaturation in the 1- or 6-position or in the 1- and 6-positions, wherein R represents hydrogen or an acetyl group, are prepared by contacting compounds of the general formula <FORM:0896913/IV (b)/2> and the corresponding compounds having in addition unsaturation in the 1- or 6-position or the 1- and 6-positions, with growing fungi of the genus Fusarium of the sections Discolor, Gibbosum and Elegans-oxysporum or oxidizing enzymes obtainable by growing these fungi, and when required, converting the products into the corresponding 21-acetates. The above process may be extended in that the 11a -hydroxy compounds are oxidized (if necessary after protecting the 21-hydroxy group) to form the corresponding 11-keto compounds.  If necessary, the 11a -hydroxy- or 11-keto-steroids prepared by the above processes may be treated to introduce double bonds simultaneously or consecutively into the 1- and/or 6-positions by treatment with chemical or microbiological dehydrogenating agents.  Thus a double bond in the 6-position may be introduced by treatment with chloranil or by bromination, e.g. with N-bromosiccinimide, followed by dehydrobromination, e.g. by means of pyridine.  An 11a -hydroxy steroid of the first general formula above containing a double bond in the 6-position may be dehydrogenated with selenium oxide, or by bromination and subsequent dehydrobromination, or by means of dehydrogenating micro-organisms such as Corynebacterium simplex or Bacillus sphaericus, to introduce a double bond into the 1(2)-position. Double bonds in the 1- and 6-positions may be introduced simultaneously into 11a -hydroxysteroids of the first general formula above (if desired after oxidation to the corresponding 11-keto compound) by first forming the 3-enol ether thereof and treating the enol ether with chloranil.  In the examples the following compounds are prepared: 11-epi-hydrocortisone, 11 - epi - prednisolone, 6 - dehydro - 11 - epi - prednisolone, 6 - dehydro - 11 - epi - hydrocortisone and the 21-acetate thereof, prednisone acetate and 6-dehydro-prednisone acetate.
