Title: Improvements in or relating to semi-mounted implements
Inventor: RICHEY CLARENCE B
IPC: A01B3/46
Filed: 1968-04-18
Abstract: 1,208,681. Agricultural implements. MASSEY-FERGUSON Inc. 18 April, 1968 [19 April, 1967], No. 18269/68. Heading A1B. [Also in Division B7] A semi-mounted implement includes an elongated frame 6 having forward connections for pivotally connecting the frame to the rear of a draught vehicle for side to side swinging movement, a ground wheel 29 for supporting the trailing end of the frame and tools e.g. plough shares Pr mounted on the frame 6 for movement between ground engaging positions and a transport position with adjusting means including a hydraulic power element 45 operable on the ground wheel to adjust its position when the tools are adjusted and to follow the side to side swinging movement of the draft vehicle. When the draft vehicle moves to the left or to the right the frame 6 pivots about spindle 15. Arm 54 moves with the spindle and activates the piston 52 in cylinder 48 of ram 44. The movement is transmitted by means of hydraulic fluid in hoses 46 to ram 45 attached to the rear of the frame and ground wheel 29 is turned in the appropriate direction by means of bell crank lever 58 and actuating arm 61. When the plough frame is rotated from one ploughing position to another or to a transport position the ground wheel is rotated by eccentric (64), Fig 7 (not shown), mounted on a plough frame sleeve 32 connected to bell crank lever 58 acting on ram 45 and hence on the actuating arm 61.

Title: A method for the production of titanium metal or a fused salt mixture from titanium tetrachloride
IPC: C22B34/12
Filed: 1951-08-02
Abstract: A fused mixture of titanium chloride and a chloride of an alkali or alkaline earth metal is produced by reacting titanium tetrachloride with the alkali or alkaline earth metal in molten form to reduce the titanium tetrachloride to a lower titanium chloride.  In an example 69 parts of sodium metal was melted in a reactor and agitated with 380 parts of titanium tetrachloride to produce a molten mixture at a temperature of 790 DEG C having a composition corresponding to the formula TiCl2, TiCl3, 3NaCl.ALSO:A method of producing titanium metal comprises partially reducing titanium tetrachloride by reaction with a molten alkali or alkaline earth metal (including magnesium) to form a salt mixture of a lower chloride of titanium and chloride of the reducing metal, forming the mixture into small lumps, and submerging the lumps in a molten mass of one of the above reducing agents to form small lumps of titanium metal which are then removed from the mass.  The titanium metal may then be purified by heating it, e.g. under reduced pressure, to a temperature at which residual reducing metal and chloride volatilize.  When potassium is used as reducing metal the reaction may be carried out under such increased pressure that the boiling point of potassium is above the melting point of its chloride.

Title: Improvements in and relating to controllers for web feeding apparatus
IPC: B41F33/18
Filed: 1934-06-22
Abstract: 423,654. Printing-machines. IGRANIC ELECTRIC CO., Ltd., 147, Queen Victoria Street, London.-(Assignees of Laabs, E. H. ; N. 12th Street, Milwaukee, Wisconsin, U.S.A.) June 22, 1934, No. 18507. Convention date, June 30, 1933. [Classes 100 (i) and 100 (ii)] Feeding webs; stopping-arrangements.- In an electric controlling-device for webfeeding apparatus for printing-presses, comprising apparatus for stopping the press motor and apparatus for severing the web, the two sets of apparatus being controlled by a common element operated upon breakage of the web, the control element is effective to operate both sets of apparatus under given speed conditions of the press, and to operate only the stopping-device under other speed conditions of the press. The printing-press is driven by a motor 1 which is controlled by a crosshead-type controller 3 operated by a pilot motor 4 to vary the resistance R for the motor. A switch 6 controls the motor circuit and is in turn controlled by a relay 7 operated by a push button 5. A relay 10 for controlling a short-circuit for the winding of the " stop " relay 7 has two windings 10<a>, 10<b>, the former being in series with contacts 11<b>, and the latter with contacts 11<a> of a relay 11. The relay 11 has an operating winding connected across the mains when the crosshead 3 driven by the motor 4 bridges certain of the contacts 12, 13, and the relay upon responding opens its normally closed contacts 11<a> and closes its contacts 11<b>. A paper-break switch 15 rests on the web, which is fed from a roll 16 to press cylinders 18. The switch is provided with two sets of contacts 14<a>, 14b, which may be in series or parallel, and are in the circuit of relay 11 and of the operating winding 21 of a web-cutter 22. If the relay 11 is energized and the web breaks, the winding 10<b> of the relay 10 operates to short circuit the winding of the " stop " relay 7 to open the switch 6 and stop the press motor 1, while the cutter 22 operates to sever the web. The relay 11 is only energized when the crosshead controller 3 has been moved to increase the speed of the motor 1 so far that a contact 12 is connected to a contact 13. At lower speeds, the relay 11 is de-energized and should a web break, the winding 10<a> of the relay 10 is energized to stop the press motor, but the circuit in this case includes a resistance r which is of such a value that the current in the circuit is inadequate to operate the web cutter 22, so that the web is not severed. When several webs are being fed simultaneously, each is provided with a paper-break switch in series with a winding 21 of a web-cutting device, these being connected in parallel with one another and in series with the windings 10<a>, 10<b> of the relay 10, thus providing for the operation of a common " stop " relay and for the operation of the web-severing devices selectively.

Title: Methods of and machines for forming hollow metal articles
IPC: B21D9/18
Filed: 1947-07-11
Abstract: 641,659. Making superheater return bends. TUBE TURNS, Inc. July 11, 1947, No. 18556. Convention date, Aug. 17, 1946. [Classes 83 (ii) and 83 (iv)] [Also in Group XI] Curving; mandrels.- In making curved tubes, e.g. superheater bends, straight tubular blanks are pushed in succession over a curved mandrel for expanding and bending the blank while simultaneously inducing a circumferential heating current in the blank over a short axial length, to heat the blank at a high rate to a temperature within the plastic temperature range, the speed of movement of the blank limiting its further temperature rise after passing the metal shaping region of the mandrel. The leading end of the tube 14a is preheated by one coil 57 and further heated by a main coil 51 shaped to provide a particular heat distribution. The mandrel 12 has a waist 12a to form a heat insulating air layer 58, and is mounted on a rod 14. The coils 51, 57 are adjustably mounted on a frame 40 having rollers 46 supporting the blanks 14a and the rod 14, and a cross-head 23 slotted to receive the rod 14 and engage the tubes 14a for pushing them over the mandrel 12 is carried by a moving cylinder 26 supported by rolls 37 and cooperating with a fixed, fluid-pressure piston. The rod 14 is detachably coupled to a tie-bar 17 and is raised into alignment with a tube trough 42 for reloading. The mandrel 12 is austenitic steel and local heating is restricted by the skin effect of using high intensity, low-frequency magnetizing current with a high reversal rate. In operation the initial heating of the mandrel is accelerated by feeding a blank slowly over it, or by leaving the heated last blank of the previous operation in place. The blanks 14a for use as return bends are curved through slightly more than 180 degrees to allow for springing contraction on cooling. Any tendency for the tubes to twist may be overcome by applying cold air jets. For blanks greater than 2¢ inch diameter 60 cycle supply is used, and for smaller blanks 360 to 10,000 cycles. Specification 517,040 and U.S.A. Specification 1,648,161 are referred to.
