Abstract: 1392160 Nickel sulphate from nickel carbonyl INTERNATIONAL NICKEL CO OF CANADA Ltd 17 Aug 1973 [17 Aug 1972] 38901/73 Heading C1A NiSO 4  is produced by the reaction of gaseous nickel carbonyl with SO 2  and O 2  at 80-250‹ C. to form a mixture of NiSO 3  and NiSO 4  which is treated to convert the NiSO 3  into NiSO 4 . The reaction may be carried out in two stages, the first at 100-150‹ C. and the second on the unreacted gases at 150-250‹ C. Ni, NiO and NiS may be produced initially but may be converted, with the NiSO 3 , to NiSO 4  by oxidation with air or O 2  or treatment with H 2 SO 4 . The CO and SO 2  may be re-cycled. The product may be dissolved in water and NiSO 4 .6H 2 O crystallized or the reaction may take place in the presence of an aqueous medium (e.g. H 2 SO 4  solution). The Ni(CO) 4 , SO 2  and O 2  may be mixed in substantially equimolecular proportions. The process may be operated continuously. CO may be used as a carrier gas and the O 2  may be supplied as air.

Abstract: 823,872. Looms with stationary weft supply. SULZER FRERES S.A. Dec. 28, 1956 [Dec. 29, 1955], No. 39510/56. Class 142(2)  A loom of the kind in which the weft is inserted into the shed by a shuttle having a thread gripper is provided with a trapping device 46 on the exit side of the shed to hold the end of the weft thread until it has been beaten up and a stop-motion feeler 48 arranged to explore for the weft thread 44 on the exit side of the shed, and the path of movement of the feeler 48 is on the side remote from the fall of the cloth of the path of the trapping member 46. A slider 86 is arranged to return the shuttle 43 towards the shed from its check position 89, Fig. 4, to a position 91 determined by the required free length of the weft and the movement of the feeler 48 is timed so that the exploring movement ends before the return movement of the shuttle to the position 91 is completed. The feeler is moved by a spring 57 towards its exploring position d, d, Fig. 3, and is returned positively to its inoperative position c, c by pawl lever 58 actuated by cams 65, 67 through links 61, 62. On weft thread absence or slackness the feeler 48 falls to the position i-i and prevents movement of the pawl lever 58 and locks the link 62 which is mounted at 8 on a spring pressed slide 69 so that the slide 69 is moved to raise a pin 76 to actuate the loom stop motion. One or more thread supporting members 104 are provided for the weft end at the position of is exploration, and by providing means for raising and lowering these members the amplitude of movement of the feeler 48 can be reduced. By providing a hooked end to the feeler, the weft can be supported by the feeler.

Title: Apparatus for measuring the length of strip
IPC: G01B21/06
Filed: 1956-12-28
Abstract: 814,266. Measuring continuous lengths of material. UNITED STATES STEEL CORPORATION. Dec. 28, 1956 [April 17, 1956], No. 39526/56. Class 42 (2). [Also in Group XL (b)] In apparatus for measuring the length of strip S moving between spaced sets of rollers 4, 32, a punch 12 makes a hole in the strip and brings into operation means for measuring the length of material passing between the rollers 4 while a photo-electric cell 42 detects the hole after it has passed the rollers 32 and brings into operation means for measuring the difference between the length of strip passing the rollers 4 and the length passing the rollers 32. When a switch 10 is depressed, the circuit to a motor 6 driving the rollers 4 is opened and a solenoid for operating the punch 12 is energized. Operation of the punch closes a switch 22 energizing a coil 20 to close a contact 20c<SP>1</SP> and open a contact 20c so that a holding circuit for the coil 20 is completed through a magnetic clutch 26 and the punch solenoid is de-energized. The clutch 26 connects a reversible and resettable counter 18 to a selsyn receiver 38 which is connected through a solenoid-operated switch 40 to a selsyn generator 8 driven by the rollers 4. When the switch 10 is released the motor 6 re-starts and the counter 18 indicates the length of strip fed into a looper pit 2 until the hole formed by the punch allows light from a lamp 44 to reach a photo-electric cell 42 which causes operation of the switch 40 to connect the receiver 38 to a selsyn generator 36 electrically connected to the generator 8 so that its output is proportional to the difference between the amount of strip entering and leaving the pit 2. Operation of the switch 40 also starts a motor 64 driving a cam 68, closes a switch 70 after a predetermined time to energize a solenoid-actuated switch 28 to break the holding circuit to coil 40, deenergize the clutch 26, and energize a clutch 58 and a motor 56 for re-setting the counter 18 to zero. When the counter reaches zero, switches inside the counter, which are also operated when the counter leaves zero, stop the motor 56 and start the motor 64 which runs until switch 70 again operates switch 28 to restore the system to its original position. Instead of punching a hole in the strip, a magnetic mark may be applied to it.
