IPC: C07J71/00
Filed: 1954-01-29
Abstract: Pseudo-isosapogenins and esters thereof are prepared by heating an isosapogenin or an ester thereof in a liquid medium consisting essentially of one or more carboxylic acids containing 2-20 carbon atoms.  The acid used is preferably an aliphatic acid such as a saturated aliphatic monocarboxylic acid containing from 6 to 12 carbon atoms.  Specific acids mentioned are acetic, n-butyric, n- and iso-caproic, n-caprylic, n-capric, myristic and oleic acids.  The above process may be modified in that the liquid medium also contains a quantity of an acid anhydride of a carboxylic acid, which is not a strong organic acid and which contains from 2-20 carbon atoms, equivalent to the amount of water produced during the reaction.  The acid anhydride employed may correspond to the acid used as the liquid medium.  A suitable acid anhydride is acetic anhydride.  The heating step is preferably carried out at a temperature within the range of from 160 DEG  to 350 DEG  C. and/or until the specific rotation of the reaction mixture reaches a maximum.  The reaction mixture resulting from the heating step may be cooled and hydrolysed with alkali, e.g. with alcoholic or aqueous alcoholic alkali.  In the case of reactants containing hydroxyl or esterified hydroxyl groups, e.g. in the 3-position, esterification or ester exchange may take place during the reaction.  Any of the following isosapogenins or esters thereof may be used in the above process: hecogenin, tigogenin, 11-keto-tigogenin, D 9(11)-dehydrotigogenin, 11a -hydroxy-tigogenin and diosgenin.  In the examples the following compounds are prepared: 3b  : 26-dihydroxy-11-keto-5a -furost-20(22)-ene, 3b  : 26-dihydroxy-5a -spirost-20(22)-en (pseudo-tigogenin), 3b  : 26 - dihydroxy - 12 - keto - 5a  - spirost - 20(22) - en, 3b  : 26 - dihydroxy - 5b  : 25D-furost - 20(22) - ene (pseudo - smilagenin), and 3b  : 26 - dihydroxy - furosta - 5 : 20(22) - diene (pseudo-diosgenin).

Abstract: 736,674. Stretching webs transversely. ROBERTSON, J. D. Feb. 5, 1951, No. 2809/51. Class 100 (1). A roll for transversely stretching or contracting webs of flexible sheet material comprises an axial shaft, a cover of resilient material and a number of annular members spaced along the shaft for supporting the cover, the central portion of the shaft being curved and the end portions being straight so that sub. stantially equal stretching will be imparted to webs of different widths ranging from that corresponding to the curved part only of the roll to that corresponding to the full width of the roll. A rigid shaft 10, Fig. 1, having a curved central portion and straight end-portions is mounted in clamps 12, such that the shaft may, by loosening the clamps, be swung about the axis passing through the clamps. A series of spaced sleeves 14 are rotatably mounted by ball-bearings on the shaft 10, while a sleeve 16 of rubber encloses the sleeves 14 and rotates therewith when engaged by a travelling web. In a modified construction, Fig. 5, the central portion of the shaft is constituted by a leafspring section 24 which is secured at one end to a straight shaft section, while at the opposite end it fits into a split clamp member 48. The leaf-spring section comprises a multiplicity of leaves of varying widths in stacked relation to provide a leaf spring of circular cross-section. Ball-bearing units 28 surrounding the spring section and spaced by sleeves 40 carry rollsections 38 which support the sleeve 16. The clamp member 48 has tapering walls co-operating interiorly with a clamp member 50 fixed to a straight shaft section 20. A screw 52 rotatably mounted, but retained against axial movement in the section 20, screws into the member 48, such that by turning a squared portion 53 the member 48 may be clamped or unclamped by the member 50. When the leaf spring 24 is unclamped, it may be bowed by an arrangement comprising a bracket fitting on each end of the shaft, the brackets being adjustable towards each other by rotating a shaft having oppositely threaded ends screwed into the brackets. The parts of the sleeve 16 which surround the straight parts of the shaft may be made of harder rubber than the central part so as to be more resistant to wear. Specification 613,450 is referred to.

Filed: 1924-02-04
Abstract: 237,935. Marks, E. C. R., (International Cigar Machinery Co.). Feb. 4, 1924. Coating-machines. - A pasting - machine principally, but not exclusively, intended for use in connection with cigar-making machines is provided with means to prevent delivery of the paste without stopping the machine. The paste, is normally delivered to a binder on a table 4 from a pasting-drum 22 revolving in a tank of paste, by a wheel 5 mounted on an arm 9, 10. This arm is pivoted near the end remote from the wheel 5 to an arm 12, which is oscillated by a rod 17 from the position shown in dotted lines to that shown in full lines, and vice versa. Moving parallel with the arm 12 is another arm 19, pivoted to the frame of the machine at 18, and connected at the top to the arm 12 by a link 21. Freely pivoted to the upper end of the arm 19 is a member 35 carrying an adjustable screw 40 arranged to coact with an axiallymovable pin 29 controlled through a cord 33 by the operator. This member 35 carries also a catch 41, which engages with a notah 42<1> on the arm 9, 10 when the pasting-wheel 5 is in contact with the pasting-drum 22. During the movement of the arm 12 from left to right towards paste-delivery position, the catch 41 remains locked until the screw 40 makes contact with the pin 29, when the lever 9, 10 is released to fall on to the binder lying on the table 4. In order to prevent delivery of paste, the pin 29 is moved out of the range of the screw 40 by means of the cord 33. When this is done. the lever 9, 10 remains locked by the member 35 above the table 4, and no paste is delivered. A spring 43 maintains contact between an adjustable screw 37 on the member 35 and an extension of the link 21. so that the member 35 moves parallel to the link 21. A further adjustable screw 38 in the member 35 coacts with the end 10 of the arm 9, 10. to arrest the fall of the arm when it is unlocked and moves off the table 4.

Title: Static inverter power supplies
IPC: H02M7/48
Filed: 1973-01-19
Abstract: 1408326 Standby systems INDUSTRIAL INSTRUMENTS Ltd 21 Jan 1974 [19 Jan 1973] 2921/73 Heading H2H In or for a no-break power supply, an inverter having an output filter has a first electronic switch (SCR5, SCR6) arranged to connect a dummy load so as to circulate current through the filter just before the real load is connected. As described, the inverter normally supplies the real load via thyristors SCR3, SCR4 which are fired on alternate half cycles by a train of pulses from a drive circuit D2. Amplifier A1 detects any disimilarity between logic waveforms derived from the inverter control circuit (not shown) and the rectified primary voltage by comparing a sum or difference of these voltages with a reference (not shown). Amplifier A2 detects any long term deterioration in the inverter output voltage by comparing the rectified and filtered secondary voltage with a reference voltage. Should an inverter fault occur, gate G4 changes a trigger T1 which changes the state of a J-K flip-flop FF1 so that drive circuit D2 is inhibited and drive circuit D3 energized so as to turn on SCR1 and SCR2 which feed the real load from a mains standby supply. When the inverter fault has been cleared, a reset circuit R1 is operated manually or automatically which first energizes a timer P1 which turns on drive circuit D1 which enables SCR5, SCR6 to convert a dummy load across the inverter output. After a time sufficient for the current in the inverter output filter to build up to the required value, drive circuit D2 is turn on so that SCR3, SCR4 connects the real load across the inverter and SCR5, SCR6 disconnects the dummy load. Zero crossing pulses are derived from a transformer in series with the inverter output and fed to a gate G5 so that the switching is performed at zero current periods. The dummy load is automatically isolated after a short period so that its continuous power rating together with that of SCR5 and SCR6 need only be a fraction of that of the system.

Title: Method of controlling cross-sectional contour of weld arc
IPC: B23K9/073
Filed: 1958-01-29
Abstract: 823,504. Influencing electric welding arcs by magnetic fields. AIR REDUCTION CO. Inc. Jan. 29, 1958 [Feb. 12, 1957], No. 2975/58. Class 39(3) In arc welding wherein current is supplied to a welding electrode and to a workpiece 16 spaced therefrom to produce an arc between them, at least four magnetic poles 28-31 of alternately opposite polarities are spaced angularly from each other and radially from the arc and directed generally transversely to the arc to create an auxiliary magnetic field which reacts with the magnetic field created by the arc to spread the arc 34 fanwise along at least one plane. The arc current and the magnetic fields created by the poles are preferably unidirectional and the workpiece is moved parallel to the direction of the plane of the arc 34 when the arc is spread fanwise in one plane only by the four poles. The workpiece may be in two abutting pieces 16a, 16b welded together along a line 35. A thin metal wire is fed continuously into the arc and a weld bead 37 is formed along the line 35 along which the heat of the arc 34 is concentrated as the workpiece is moved in the direction of the arrow 36 parallel to the plane of the arc. The poles 28-31 may be permanent magnetic poles or electromagnets. When the arc is used for surfacing, the workpiece is moved transversely to the arc. A continuously fed filler wire may be used to coat aluminium bronze over steel. A.C. may however be fed to electromagnets 28- 31 connected in series and are wound so that the poles are alternatively of oppositely polarities. When A.C. is used in the magnets and D.C. in the arc, or when an A.C. arc is used with D.C. or permanent magnets, the plane of the flattened arc moves through 90 degrees. at half cycles. When A.C. is supplied to the arc and also to the magnets, then on proper synchronization, a single fan-shaped arc 34 is obtained. By the use of six magnetic poles of alternately opposite polarities, spaced at equal angles from each other and at equal radial distances from the arc, an arc of Y-shaped cross-section is formed. By using eight magnetic poles of opposite polarity an arc of X cross-section is formed. Apparatus for mounting a non- consumable electrode with means for supplying a consumable metal wire, an inert gas and a cooling water supply is disclosed (Fig. 1, not shown).
