Title: Process for copolymerizing ª‡-olefines with ª‡-alkenylheterocycles
IPC: C08F210/00
Filed: 1965-08-12
Abstract: Copolymers of alpha-olefines of the general formula CH2=CH-R, where R represents H, alkyl, aryl, or alkylaryl, with an alpha-alkenylheterocyclic compound of the general formula <FORM:1078767/C3/1> where n is an integer of from 1 to 12, x represents oxygen, sulphur, or nitrogen and R1 is absent if x represents oxygen or sulphur, and R1 represents an aryl, alkyl, aralkyl, or cycloalkyl radical if x is nitrogen, which heterocycle may be condensed, unsubstituted, or substituted one or several times by an alkyl, cycloalkyl, aryl, alkoxy, aryloxy, halogen, or dialkylamine radical, are made by copolymerizing the monomers in the presence of a catalyst comprising TiCl4 or TiCl3 and an aluminium trialkyl and/or a halogen-containing organoaluminium compound. The copolymerization may be effected by sequentially polymerizing the monomers to give a block copolymer. Specified alphaolefines are ethylene propylene, butene-1, 3-methylbutene-1, pentene-1, 4-phenylpentene-1, 4-phenylbutene-1, 5-phenylpentene-1, hexene-1, and styrene.  The heterocyclic monomer may be 4-furylbutene-1, 6-furylhexene-1, 12-furyldodecene-1, 11-thenylundecene-1, 5-thenylpentene-1, 4-thenylbutene-1, or 3-thenylpropene-1. The copolymerization may be effected in bulk or in a hydrocarbon diluent. The copolymerization is a mixture of crystalline copolymers and amorphous oily polymers.  The TiCl3 component of the catalyst is preferably obtained by reducing TiCl4 with an organo-metallic aluminium compound.  The polymerization is terminated by addition of n-butanol.

Abstract: 1510889 Applying adhesive tape J & H MFG Inc 8 Sept 1975 [12 Sept 1974] 36839/75 Heading B8F A photographic film print strip is moved along a course of travel, and a strip composed of a transferable pressure sensitive adhesive layer on a releasable backing strip is confined by a guide to an elongate path aligned with that course of travel, and the strips are brought together to be become engaged, whereby the result may be cut into individual prints from which the backing can be removed to leave an adhesive layer behind. In the Fig., a strip 14a of film prints is fed from reel 14, under roller 16, and into a channel defined by side members 32. The strip is advanced intermittently and severed while stationary to form a stack of individual prints. Entrained with the strip 14a are two strips 36a, 36a<SP>1</SP> of pressure sensitive adhesive transfer tape, so that the tapes can be peeled off a severed individual print to leave two strips of adhesive for mounting the print. Each tape is dispensed by an apparatus consisting of a mount - ing plate 32, shown in full lines in the operative position and in phantom in the position for changing a reel 36 of tape. The reel is driven by motor 30 through shaft 34, and the tape is conducted over roller 40 on arm 38, guide rolls 51, 52, and guide channel device 27 including a hold down 65. Motor 30 is driven intermittently by operation of switch 42 as the loop of tape formed about roller 40 is used up. When the tape is used up, arm 38 drops and actuates switch 44 to stop the print strip feed and cutter mechanisms, or to actuate an indidicator. In an alternative, Fig. 7 (not shown), to avoid the need for a power supply to motor 30 advancement of strip 14a pulls the strips 36a, 36a<SP>1</SP> off their respective reels which are braked by the tensions applied by the tapes to their respective arms 38 (38<SP>1</SP>).

Title: Improvements in or relating to electric motor control systems
Inventor: FRIEDLANDER ERICH SIEGFRIED
IPC: H02P29/00
Filed: 1954-12-03
Abstract: 773,624. Control of A.C. motors; controllers. GENERAL ELECTRIC CO., Ltd. Nov. 28, 1955 [Dec. 3, 1954], No. 35095/54. Class 38(3) A winder motor 1 is energized through three-phase supply-lines 2 for driving operation, and, during dynamic braking operation, the stator winding is excited by direct-current derived from three-phase supply 7 through' control reactor 8. rectifier 9, and contactor 10. A rotor resistance 4 is controlled by a pair of pilot motors 14, 15, having opposing torques, and,for driving operation of the winder motor, the armature of the pilot motor 14 is energized from the current transformer 23 through rectifier 24, the motor 14 tending to raise the value of the resistance 4. At the same time, the armature of the pilot motor 15 is supplied from rectifier 18 through resistor 12 which is regulated by the driver's control lever 11. Thus the value of the resistance 4 is maintained at a fixed ratio with regard to the slip frequency and this is dependent upon the positidn of the control lever 11. For dynamic braking the motor 14 operates to reduce the rotor resistance and its armature is supplied in accordance with the secondary voltage of the winder motor through reactors 26 (preferably saturated) and rectifier 24. The armature of the motor 15 is supplied at constant voltage from the rectifier 18, the reversal of the functions of the pilot motors being effected by reversal of field excitation through opening of contacts 19 and closure of contacts 20. Control of dynamic braking is effected through the reactor 8, contact 28, and resistor 12. The motor 14 will tend to lower the value of the resistance 4 until the rotor voltage has fallen to such a value that the current through reactors 26 corresponds to that necessary to counter-balance the constant torque of the motor 15. Thus, the ratio between the rotor resistance and speed of the winder motor is kept constant during the dynamic braking operation. When the resistance.4 is approaching its lowest value a switch 30 is opened by projection 31 so that a greater portion of resistor 29 is included in the armature circuit of the motor 15. In a modification, a two-phase motor is coupled to the mechanism for regulating the rotor resistance and is provided with a brake motor, having a squirrel cage rotor and permanent magnet poles, to prevent over-shooting, Fig, 2 (not shown). The two-phase motor is controlled by a magnetic amplifier having a bias winding as well as a winding excited either by the current transformer 23 or the sliprings 3, and a winding excited under the control of the resistance 12 during driving and from a constant source during dynamic braking operation. A special compensating winding.of the magnetic amplifier is energized during dynamic braking in accordance with the amount of braking being applied so as to enforce a variation of the rotor voltage per cycle with varying directcurrent.
