Title: Machine for sinuously bending a pipe
IPC: B21D11/07
Filed: 1973-01-23
Abstract: 1377045 Bending metal tubes TSENTRALNY NAUCHNO-ISSLEDOVATELSKY INSTITUT TEKHNOLOGII MASHINOSTROENIA 23 Jan 1973 3401/73 Heading B3E A machine for bending a pipe into serpentine shape comprises means for moving the pipe along its axis towards a rotary table, the table being movable transversely of the pipe, two clamps mounted on and movable vertically relative to the table, and a fixed sleeve guiding the pipe towards a fixed heater. As shown, the table 10 is rotatable in a ring 2 by worm 13 and motor 18, and the table is reciprocable by a pneumatic cylinder 9 on rods 5 between stops 56 simultaneously adjustable by hand wheel 63. Each clamp 30 and its pneumatic operating cylinder 31, Fig. 12, is mounted on a slider 22 movable in guides in a cut-out 21 in table 10 by a hand wheel 28. The hinge 65 of the clamp is secured to a member 66 urged upwardly by springs 71 to a limit position defined by nuts 69, so that retraction of the cylinder causes release and then lowering of the clamp, and extension of the cylinder causes raising and then clamping of the clamp. The pipe is advanced by a motor 48 driving lead screws 44 which reciprocate a clamp 40 similar to clamps 30, but not movable vertically. At the beginning of a bending cycle, the mechanism is disposed as in Fig. 1; the pipe passing through the fixed sleeve 51, Fig. 7, indication heater 53, and being held by one clamp 30. Motors 18 and 48 are energized, so that clamp 30 forms a first 180 degree bend, the pipe being fed at a faster rate than the speed of movement of the clamp to avoid thinning of the bend wall. The clamp is released and lowered, the pipe fed on by the required distance between bends, and the table moved to the other end of rods 5. The other clamp is raised and clamped, to give the position in Fig. 7. The second bend is then made by reverse rotation of the table, and the disposition of Fig. 1, resumed to complete the cycle. The eccentricity of clamps 30 relative to table 10 and the positions of stops 56 are set on wheels 28, 63 to suit the desired radius of bend, and the clamp jaws, sleeve 51 and heater 53 are replaceable to suit different pipe diameters.

Title: Apparatus for converting mechanical energy into heat
IPC: H05B3/68
Filed: 1957-02-04
Abstract: 858,179. Electric heating by induction. BAERMANN, M. Feb. 4, 1957 [Feb. 4, 1956 ; April 28, 1956], No. 3838/57. Class 39(3). In apparatus for heating, by eddy current and/or hysteresis effect, objects which consist wholly or partially of an electrically conductive or magnetically permeable material, a multipolar magnet assembly is used which consists at least at the ends of the poles, of a permanent magnetic material with a preferred magnetic direction which is parallel to the direction of magnetisation. In Figs. 1, 2, a disc 6 of ferromagnetic material is rotatable by an electric motor 4 and carries permanent magnets 7 magnetised perpendicularly to the plane of the disc such that alternate north and south poles are disposed side by side. A non-metallic plate 8 which may be of plastic supports a pan 12 having a ferromagnetic insert 13 and formed of a good electrical conductor, e.g. copper. Magnets 11 having pole pieces 10 are let into the plate 8 and serve to hold the pan in position. Rotation of the disc and the magnets 7 produces heating of the pan due to eddy currents and hysteresis effects. In a modification, Figs. 3, 4, a rotatable disc 31 carrying magnets 40 is slidable vertically on a motor shaft 30 and is normally urged upwardly by a spring 34. Laminated pole pieces 42 are located in a temperature-resistant and electrically insulating plate 41 which is faced with a protective plate 50 having a drain channel 51. Radially magnetised annular magnets 44, 45, coact with a ferromagnetic ring 54 provided on a pan 53 to hold the pan in position. Overloading of the motor 29, e.g. by using too many utensils, is prevented by repulsion between the pole pieces 42 and the magnets 40 which causes the disc 31 to be depressed against the tension of the spring 34 and the air gap between the magnets and pole pieces to be increased. In a further modification, Fig. 5 (not shown), the upper surfaces of the magnets on the rotatable disc are inclined towards the outer edge of the disc and the larger air gaps thus provided at the magnet edges furthest away from the centre of the disc result in more even heating of the base of the pan.

Filed: 1929-02-05
Abstract: 328,348. Siemens Bros. & Co., Ltd., and Goodwin, W. E. Feb. 5, 1929. Desk and table sets; supporting.-In a telephone instrument, the contents of which are operated by the weight of a hand micro-telephone on a movable platform, the ends of the platform are prevented from turning bv guides projecting into open recesses in the forked ends of the cradle support. The crade 3, Fig. 1, is secured by screws to the casing 2, the screws also securing the tubular casting 5 which carries a plate 6, on which the terminals and contact springs are mounted. The spindle 7, which carries the platform 8, is journaled in the casting 5 and operates the contact springs 15, being fitted with a light compression spring 10; the lower end of the spindle is formed as an insulating cam. The platform 8, which may be of insulating material, has its ends bent at right-angles to its length to form guides sliding freely in open grooves or recesses 9, Fig. 2, in the ends of the cradle. A removable pin 13 in the spindle 7 limits the travel of the platform when the telephone is removed so as to prevent the guides disengaging from the grooves 9. The platform is made wider than the hole for the spindle, thus preventing the entry of dust inside the casing 2. For instruments used in automatic telephone systems the dial is fixed to the mounting 14, Fig. 3.

Title: Improvements in or relating to the separation or partial separation of components ofa liquid medium
IPC: C13B30/02
Filed: 1958-02-06
Abstract: A crystallizable constituent is separated from a liquid in a number of successive crystallization stages, liquid from an intermediate stage passing to the preceding stage while solid from said intermediate stage is melted and passed to the following stage.  A portion of the melted solid may pass back to the said intermediate stage as reflux.  The process may be continuous or intermittent.  As shown in Fig. 1, a liquid is fed from a valved inlet 15 to form a layer 13 in a rotary cylinder 1 which may be partially immersed in a cooling bath 20 and which has one or more helical blades 2 forming a spiral path along the inner periphery of the cylinder.  During rotation of the cylinder, liquid passes to the left while the crystallizable constituent passes to the right in spiral flow, rising as a crystalline layer and returning as a liquid, optionally after being melted by an external heating element 21.  In a modification (Figs. 4 and 5, not shown), the heating element is situated within the cylinder in the form of a rotary spiral scraper intermeshing with the <PICT:0900108/III/1> <PICT:0900108/III/2> <PICT:0900108/III/3> <PICT:0900108/III/4> blades 2.  In a further modification (Figs. 7 and 8, not shown), the crystalline layer may form on a rotary hollow coil associated with a heated scraper within the rotary cylinder.  In a further modification (Fig. 8, not shown), the hollow coil may be associated with a horizontally displaceable U- or V-shaped heated scraper having spaced apertures for return of melted solid.  As shown in Figs. 10 and 11, the liquid and crystallizable constituent pass in opposite directions in a zig-zag path formed by wedge-shaped partitions 51 in a trough 50, one end of the trough being cooled by bath 20 while the other end is heated by one of heaters 21.  Tipping to produce the desired flow and rocking to alternate the heating and cooling is effected by four hydraulically operated reciprocating rods 53, one at each corner of the trough.

Abstract: 607,563. Electromagnets. TRIX, Ltd., anp ALTMAN, W. Feb. 8, 1946, No. 3991. [Class 35] [Also in Group XXXVII]  An electromagnet for actuating a rocking member which may be used in toy railways for operating signals, points, &c., comprises two electromagnets 1, 2 which attract the rocking armature member 6 in a direction determined by which winding 3, 4 is energized. The magnets are provided with additional polepieces 9, 9a in front of which is a second armature 7 pivoted at 8 and carrying a contact arm 10. Fig. 2 shows the normal position of the armature 7 in which the contact 10 is kept in engagement with a fixed contact 11 by a spring 14. A small current from a source 13 energizes the magnet 1 which attracts the member 6 into the position shown, but is insufficient to attract the armature 7. If the voltage of the source 13 is raised the current through the winding 3 is increased and the armature 7 is attracted to the polepiece 9. The contact 10 now engages a second fixed contact 12, thus interrupting the current through the winding 3 and completing the circuit through the winding 4 and causing the member 6 to rock towards the magnet 2. The armature 7 may be actuated by a separate electromagnet in parallel with the magnet 1.
