IPC: D06B3/04
Filed: 1923-04-19
Abstract: 212,146. Nuttall, H. April 19, 1923. Passing materials through liquids.- A series of dye-vats to which yarn in sheet form is fed so that different sections of the sheet are differently dyed is combined with a yarn-drying chamber provided with a wince and a fan rotating in opposite directions. The vats 1 containing different dye-liquors carry guide-rollers 5 - - 7 and beams 3 on which rollers 4 are mounted. The drying chamber 9 encases a rotating wince 13 and has an inlet 14 for air and an outlet 15 in which is mounted a fan 16. The chamber is heated by steam pipes 11 arranged in serpentine formation. The wince and the fan are driven in opposite directions by mechanism comprising, as shown in Fig. 5, a shaft 25 which drives the fan 24 and on which the wince 13 is loosely mounted; the wince carries a toothed ring 26 which gears with a pinion 29 mounted on the framework of the chamber, the pinion 29 meshing with a pinion 28 driven by the shaft 25. In operation, the yarn sheet x passes from the roller 17 over rollers 18, 19 and thence around the wince; on leaving the drying- chamber it passes by way of rollers 20, 21 to the roller 22. A section of the sheet may then be diverted through the first vat 1, passing over the rollers 6, 7 attached thereto, while the remainder passes to the roller 5 of the first vat and thence to the roller 5 of the second vat, where a further section may be diverted. The remaining vats are similarly operated, and the various sections finally reassembled.

Title: Improvements in guillotine machines for cutting paper and other materials
Inventor: FAWDRY CHARLES FREDERICK
IPC: B26D1/08
Filed: 1948-04-16
Abstract: 640,077. Guillotine machines. SOAG MACHINE TOOLS, Ltd. April 16, 1948, No. 10678. [Class 31 (i)] A guillotine machine is provided with a work-holding clamp actuated through a slipping clutch, the load at which the clutch commences to slip being determined by the resistance offered to an auxiliary member tending to move with one of the clutch parts, means being provided for varying such resistance at will. As shown in Figs. 3 and 4 a rock-shaft 3 controlling a work clamp and which may be operated through a pedal (not shown) has secured to one end a clutch drum 4<SP>1</SP> engageable by shoes 7, 8 pivoted at 9, 10 on an annular member 11 free to oscillate about the shaft 3. The adjacent ends of the shoes are connected together by toggle links, an arm 21 connecting the two sets of links. An arm 26 connected to one of the toggle mechanisms has secured thereto one end of a shaft 27, Fig. 3, pivotally supported in the annular member 11, the other end of the shaft being secured to an arm 28 which engages in a slot (not shown) formed in the boss of a brake drum 32, Fig. 7, mounted on a sleeve extension 12 of the member 11. The brake drum is embraced by a band 44 secured to a bell-crank lever 46, the pressure of the band on the drum being adjustable by means of a spring-loaded rod 49 actuated by a hand wheel 56 to which is coupled an indicator 63. Operation of a starting lever, not shown, causes rod 36, which is pivoted to the member 11, to effect one complete reciprocation. Downward movement of the rod 36 causes the member 11 to turn initially in a clockwise direction, Figs. 4 and 7, which movement is resisted by the braking effort applied by the band 44 to the drum 32 when the latter turns. The drum is then locked, causing the arm 28 to turn the shaft 27 and arm 26 to operate the clutch shoes 7 and 8 which grip the clutch drum 4. The drum 4 and rock-shaft 3 thus turn with the member 11 and the work-holding clamp is operated from shaft 3, descending in advance of the guillotine which is operated through rods 67. Subsequent upward movement of the rod 36 causes the apparatus to return to its initial condition.

Patent GB-775000-A (GB)
Title: Method of, and apparatus for, manufacturing pipe bends
IPC: B21D9/12
Filed: 1953-05-23
Abstract: 775,000. Making pipe bends; bending; drawing; tube expanding; rolling; mandrels. FERGUSON, J. M. Aug. 23, 1954 [May 23, 1953], No. 11179/53. Classes 83 (2) and 83 (4). A method of making pipe bends comprises subjecting a length of straight pipe to radial compressing, radial expanding, and bending operations, the compression due to the radial compressing being greatest at that part of the pipe which will form the outside of the bend and least at that part which will form the inside of the bend, the expansion being least at that part which will form the outside of the bend and greatest at that part which will form the inside, the amount of compression at any point on the pipe produced by the compressing operation being so related to the amount of expansion and longitudinal compression at the same point on the pipe produced by the expanding and bending operations that the wall thickness of the finished bend is substantially the same as the wall thickness of the straight pipe. In the apparatus shown in Fig. 1 the pipe 13 to be bent is passed over a mandrel 1 in the form of the frustum of an oblique cone to effect the expanding, through a converging die 2 and then over a bending mandrel 3. In another embodiment, Fig. 3 (not shown), the die 2 is placed before the mandrel 1. In another embodiment, Fig. 2, the pipe 13, after expansion on the mandrel 1, is first compressed and then bent by a die 6 formed with a straight converging passage merging into a curved passage of constant diameter. In another embodiment, Fig. 4 (not shown), the pipe 13 passes through the die 2, over the mandrel 1 and then into a curved passage of constant cross-section in a bending die. In a further embodiment, Fig. 5, after passing over the mandrel 1 the pipe 13 enters a die 7 formed with a curved converging passage which performs the compressing and bending operations simultaneously. In another embodiment, Fig. 6, the pipe 13 passes through the die 2, heated by an induction coil 12, and over a curved mandrel 4 of increasing diameter in cross-section which expands and bends the pipe 13 simultaneously. In a further embodiment, Fig. 7, wheels 8 and slippers 9 co-operate to compress the pipe 13, the mandrel 1 expands it, and a slipper 10 cooperates with a forming wheel 11 to bend the pipe. The apparatus of Fig. 6, may be used to bend two pipes, one inside the other, the inner of nickel and the outer of mild steel, for example to form a two-ply pipe bend. A longitudinallywelded or brazed pipe may be bent, the pipe being so positioned that the maximum radial compressing pressure is applied at the seam. The pipe may be heated during any of the operations by gas jets, surface combustion burners, electrical resistance heating or electrical highfrequency induction heating. A lubricant such as dry or colloidal graphite or powdered glass, dry or in suspension, may be used.

Title: Chopper amplifiers
Inventor: SWARBRICK RICHARD
IPC: G05D3/14
Filed: 1969-03-03
Abstract: 1,261,641. Control of A.C. motors. HONEYWELL Ltd. 2 March 1970 [3 March, 1969], No. 11273/69. Heading H2J. [Also in Division G1] In a self-balancing system, a two-phase servomotor 28 drives an indicator and is coupled to the slider of a potentiometer 3 to provide positional feed-back which is compared with a D.C. signal applied to terminals 1, 2. The D.C. signal comprises a stray component at mains frequency which is applied to the motor as a signal at twice the mains frequency whereby the stray component does not cause undesired driving of the motor. The deviation signal across terminals 1, 2a, is chopped by field-effect transistor 4 which is driven by a signal from mains transformer 7 through full-wave rectifier 9 and a unit 10 for producing square-wave pulses at twice the mains frequency. The chopped signal is transmitted through amplifier 11 to an inverter which inverts alternate portions of the signal so that the output terminal 12 presents a mains frequency signal but with the frequency of the stray signal effectively doubled. The inverter comprises a transistor 13 producing in-phase and anti-phase versions of the chopped signal at its emitter and collector respectively. Transistors 22, 23, are rendered conductive by successive half-cycles of the output from transformer 7 whereby the in-phase and anti-phase components are transferred to the terminal 12 alternately. The signal from the terminal 12 passes through a shaping circuit 29 to the motor 28.
