Title: An improved automatic metal tube bending machine
IPC: B21D7/12
Filed: 1942-11-26
Abstract: 561,003. Angular bending. PARKER, A. LA R. Nov. 26, 1942, No. 16780. [Class 83 (iv)] A power-operated tube-bending machine has power-operated means for feeding the tube, after a bend has been made, so that another bend can be made therein. Assuming that the bending-former 1 has been returned to its initial position by the spring 47, that the guide 17 and clamp 13 are withdrawn, and that the tube-feeding carriage 21 is adjacent the former 1, the tube 12 to be bent is inserted, from the right, over a mandrel 28 and through the clamp, guide, and carriage to abut an adjustable stop 27. The wheel 26 is then turned to clamp the tube 12 to the carriage. The push button 48, Fig. 5, is then closed to complete a circuit from the power line L<1> through a switch 49, line 50, solenoid 51, and switch 53 to L<3>. This will close the switch 52 to start the motor 38 which will act through belts 39, 43 and screw 22 to move the carriage to the left until it engages the switch 53, Fig. 1, to break the circuit through the motor 38 and close a circuit through solenoids 15, 19 thus stopping the carriage 21, closing the clamp 13, and correctly positioning the guide 17. This is attached to, and moves into the position shown, the switch 49 which closes a circuit through a solenoid 10 thus closing a clutch 8 and switch 55 and causing a continually rotating motor 3 to rotate the former 1 and effect the bend and the circuits through the solenoids 15, 19 to be maintained when the switch 53 is released. During the bending operation the carriage 21 is advanced at the correct rate by variable speed friction gear 44, Fig. 4. When the advancing carriage engages a switch 54, Figs. 1 and 5, the circuit through the solenoid 10 is broken, thus retracting the clutch 8, clamp 13, and guide 17, and a circuit through a solenoid 57 and switch 59 is closed, thus closing a switch 58 and starting the motor 38 to advance the carriage and tube. When this reaches the desired position for the next bend, the carriage engages the switch 59 to break the circuit through the solenoid 57 thus stopping the carriage and closing a circuit through a solenoid 61 and switch 65 thus closing a switch 62 and causing a motor 37, Fig. 2, to act, through' gearing 36, 35, shaft 33 and chain 31, to rotate the tube clamp 24 until an arm 63 or 64, Fig. 1, thereon engages a switch 65 to break the circuit through the solenoid 61, thus stopping the motor 37, and close a circuit through the solenoids 15, 19 thus re-starting the cycle of operations. Any number of the switches 54, 59, 65 may be arranged in adjusted positions along the supports 46, 66 to form the desired bends. In Fig. 5 four of each of such switches are shown.

Title: Improvements in or relating to apparatus for testing yarns
IPC: G01N3/08
Filed: 1931-06-10
Abstract: 369,806. Testing strength of yarn. DIETZ, H., Harleshausen, near Cassel, Germany. June 10, 1931, No. 16862. Convention date, June 10, 1930. [Class 106 (ii).] Relates to apparatus for continuously testing the tensile strength of yarn in which the yarn is fed continuously and formed into a loop carrying a weighted body which tears the yarn when a portion of reduced strength is passing, and comprises a conical roller mounted upon a threaded spindle adapted to be displaced relatively to the frame automatically when the length of the loop departs from the normal so as to restore it to normal. A rotatable pulley 2 mounted on a lever 3 carrying a weight 4 is located in a loop 1 of the yarn to be tested. Pins 5 on the ends of the lever are adapted to co-operate with inclines 6 on the vertical limbs of two three-armed levers 7 the arms 8 of which carry contacts 9 adapted to engage mercury contacts in cups 10, 11, these contacts being in the circuits of solenoids 13, 14 respectively. The thread 1 passes over a conical roller 34 loose on a spindle 33 which is screwed to move axially. This spindle may be turned one way or the other to shift the pulley 34 axially by means of a reversing gear controlled by the contacts 10, 11. A motor 36 drives through a cord 18 a shaft 22 on which are toothed wheels 21, 20 which respectively drive the shaft 23 in one direction through wheels 20, 24 and in the opposite direction through wheels 21, 25, 26. Normally the clutch member 29 is pulled by a spring 31 into engagement with the wheel 26. When the loop lengthens the right-hand pin 5 engages the incline 6 and tilts the lever 7 to make the contact 10 thus energizing the solenoid 12 which attracts its armature 14 and lifts a lever allowing a spring latch to throw in a one-way clutch to allow the shaft 22 to be driven. The movement is transferred to the shaft 33 and the pulley 34 slid axially to cause the loop to shorten. When the lever 3 tilts in the opposite direction, the contact 11 is made and the solenoid 13 energized to clutch in wheel 24 whereupon the shaft 33 is rotated in the opposite direction.

Title: Manufacture of esters and ethers of ethylidene-glycol and vinyl alcohol
Filed: 1922-06-19
Abstract: Ethers and esters of ethylideneglycol and vinyl alcohol are produced by passing acetylene together with the vapour of compounds containing hydroxyl or carboxyl groups over heated catalysts, especially metals, their oxides, and salts.  Examples of suitable catalysts are cadmium, zinc, mercury, magnesium, barium, copper, silver, cerium, nickel, and iron, or their compounds, preferably mounted on a support such as charcoal, pumice, or infusorial earth.  The reaction may be carried out under increased or reduced pressure; and is preferably conducted as a cyclic process, the unchanged hydroxyl or carboxyl compound being continuously separated from the product and returned with fresh acetylene into the reaction chamber.  According to the example, equal volumes of acetylene and acetic acid are passed at a temperature of 200 DEG  C. over charcoal impregnated with cadmium acetate; ethylidene diacetate and vinyl acetate are isolated from the condensed product by fractional distillation.

A device responsive slowly to small overloads and instantaneously to large overloads comprises a magnetic member 37 that is operable either by movement of a bimetal strip 35 or by the magnetic effect of current through the straight conductors 1, 2 to close contacts to energize an electromagnet 50 which by attracting the member 37 completes its movement and breaks the circuit of a contactor controlling the main circuit. The main current passes through the conductor 1 to a U-shaped member 33 supporting one end of the U-shaped bimetal strip 35 and thence through the strip 35 to a U-shaped member 34 and the conductor 2. A magnetic channel-shaped member 30 embraces and is magnetized by the conductors I, 2 so as to attract the member 37 which is pivoted by means of a blade-spring 39. The member 37 carries an adjustable screw, adapted to be engaged by the bimetal strip where it bends, and an armature for attraction by the coil 50. It also carries on its two arms studs such as 48 for operating two pairs of contact strips, the movement of the member 37 closing one pair and thereby energizing the electromagnet 50 before it opens the other pair and thereby breaks the contactor circuit.

Propelling and steering by paddle wheels; propelling and steering by vibrating fins.-A paddle wheet wherein the axis of the blade describes a surface of revolution and also makes half a revolution about its own axis is provided with independent and separate driving and feathering means which can be adjusted and replaced independently. The paddle 17 is ball mounted at 18 and connected at 14 with a driving pin 5 supported on a crank 3 along which it may be adjusted for varying the stroke. In addition, gears 10, 9, 12, 6, are carried by an arm 7 which can be set in any desired position for adjusting the phase. In an alternative form the stroke variation is effected by actuating the driving pin from two eccentrics 21, 22 adjustably supported in slides 25, 26. In this case a simple train of wheels 28, 29 is employed for the phase adjusting. For movement of the axis in a cylindrical path the blade is attached directly to the driving pin 5 and is not ball mounted. In one modification the train of wheels for alternating the phase is of the bevel kind. The driving means when in the form of an electric motor may be carried by frame either fixed to the craft or by a frame which supports the blade axis. In either case the blade axis frame is pivotally mounted so that different degrees of tilt may be given to it for altering the stroke. Specifications 277,384, 294,109 and 315,996 are referred to.
