Title: Ultra-high molecular weight oxirane polymers
IPC: C08G65/12
Filed: 1968-06-18
Abstract: 1,249,491. Wells- PETROLITE CORP. 18 June, 1968 [24 July, 1967], No. 28990/68. Heading E1F. [Also in Divisions B1 and C3] A water-in-oil or oil-in-water emulsion, for example a petroleum emulsion formed in the extraction of oil from wells, may be demulsified by mixing the emulsion with an ultrahigh molecular weight oxirane polymer prepared by polymerising an oxirane compound in the presence of a catalyst composition comprising (i) an organoaluminium compound, (ii) an organic nitro compound and (iii) a chelating agent and/or water., The polymer may be used "down-the-hole", i.e. introduced into the well, either in solid form, for example as sticks, pellets or chunks either alone or in admixture with for example naphthalene, or in suspension in for example water or in  solution in for example an aromatic hydrocarbon, for example benzene, toluene or xylene, an alcohol, for example methanol, ethanol, propanol, hexanol, octanol or denatured alcohol, cresol, acetone, carbontetrachloride, tar acid oil, pine oil, anthracene oil or a sulphur dioxide extract obtained in the refining of petroleum. The polymer, which may be in admixture with other demulsifying agents (none specified), may be used to prevent the formation of an emulsion rather than in demulsifying an emulsion already formed. Reference also is made to the use of the polymer in other applications relating to oil wells, for example in oil well fracturing and acidizing.

Title: Improvements in or relating to electric welding system
IPC: B23K11/24
Filed: 1934-10-15
Abstract: 431,985. Electric welding. IGRANIC ELECTRIC CO., Ltd., 147, Queen Victoria Street, London.-(Assignees of Stansbury, C. ; 315, North 12th Street, Milwaukee, Wisconsin, U.S.A.) Oct. 15, 1934, No. 29450. Convention date, Oct. 13, 1933. [Class 83 (iv)] [See also Group XXXV] A welding system for supplying welding jaws 1, 2 comprises means for moving the jaws to exert a pressure upon the material to be welded and a discharge device for effecting closure of the supply circuit to the jaws for a predetermined interval. The arrangement is such that the pressure is maintained on the jaws for an adjustable interval after the supply has been interrupted. The circuit arrangement is brought to a condition ready for operation after the main circuit has been completed, by the valve 16 becoming conductive and causing contacts 15b, 15c to open and contacts 15d to close and by a thermal relay 19 causing, after a time interval to allow the valve to warm up, the switch 17 to lift and complete a maintaining circuit for itself. A welding cycle is initiated by closure of press-button switch 21. The switch 13 lifts, closing its own maintaining circuit, and energizes switch 12 which in turn energizes a solenoid 9 operating a valve 8 which allows pressure fluid to be admitted to the device 7 to apply pressure to the work between the jaws 1, 2. When the pressure reaches the required value a pressure switch 10 closes contacts 10b and opens contacts 10a. The valve 16 becomes nonconductive due to the opening of contacts 10a and switch 15 drops energizing switch 11 through the contacts 15b and completing a discharge circuit through a resistance 26 for the condenser 25. Operation of switch 11 completes the circuit of switch 14 which connects the supply from the A.C. mains L1, L2 to the jaws 1, 2 through a transformer 4. The period of application of the supply is determined by the resistance-condenser combination 26, 25. When the condenser has discharged the valve becomes conductive, the switch 15 lifts and de-energizes the switch 11 which de-energizes switch 14 and supply to the jaws is cut off. Opening of switch 11 deenergizes switch 13 which results in a delayed opening of switch 12 due to the resistance 22 in circuit. Opening of switch 12 causes shutting of the valve 8 and release of the pressure in the jaw so that the pressure is released a predetermined time interval after the supply has been switched off, to allow of cooling of the work. Specification 398,377, [Group XXXVII], is referred to.

Abstract: 712,733. Photo-electric pin-hole detectors. UNITED STATES STEEL CORPORATION. Nov. 24, 1952 [March 18, 1952], No. 29612/52. Class 40 (3) Apparatus for testing a roll of steel strip for pinholes with a photocell before being tinned and cut into sheets comprises means for marking the strip at the pinhole, and actuating a deflecting gate subsequently by means of a mark detector in combination with photocells sensitive to the leading and trailing edges of the sheet to deflect the reject sheet on to a reject pile. As shown, a strip of metal S is examined by a light source 20 and photo-cell 22, the presence of a pinhole producing a pulse which is amplified at 24 to actuate a magnetic marker 26 at approximately the same place on the strip as the pinhole. After treatment and shearing into individual sheets S', the magnetic mark on the faulty sheet S<SP>1</SP> is sensed by a detector 34 to produce via amplifier 42 a positive bias on a thyratron 44 to cause it to conduct, whereupon a negative pulse is sent to the grid of a further thyratron 50. When the leading edge of the faulty, marked sheet S' passes between a light 28 and photocell 30 a negative pulse is sent to the anode of valve 44 to extinguish this valve, thereby sending a positive pulse to valve 50 and causing it to fire, energizing a relay coil 56 in its anode circuit, followed by solenoid 60 to actuate a deflector gate 14. The trailing edge of the marked sheet produces a pulse in a further photocell 32 which is amplified at 64 to extinguish valve 50, thereby restoring the gate 14 to its normal position. The strip marking may be other than magnetic.

Title: Improvements in or relating to rotary folding mechanism
IPC: B65H45/16
Filed: 1939-11-09
Abstract: 535,717. Folding paper; sheet associating apparatus. QUICK. C. G., and WHITEHEAD, W. A. Nov. 9, 1939, No. 29768. [Class 100 (i)] A rotary folding machine in which blades 2 can fold uncollected sheets into rollers 3, 4 for newspaper work, or can fold collected sheets which are associated on pins 17 for magazine work is constructed so that the setting of the mechanism for actuating the blades 2 correctly automatically operates the mechanism for releasing the impaling pins 17 at the required times. To adjust the operation of each folding blade 2, which is a radial blade only, an adjustable cam plate 9, Fig. 3, is fitted to the folding machine and a cam surface 11 engages one of the rollers 7 on the arm 6 of the folding blade 2 and rotates this arm through 180 degrees when the blade is passing the rollers 3, 4. The cam 11 has tracks 12, 13 concentric to the cam-track 8 which keeps the arm 6 tangential to the folding cylinder. Since the cam 11 rotates the blade shaft for half a revolution, the blade operates once in two revolutions and thus folds two sheets collected on the pins 17. A second cam plate having two cams similar to the cam 11 can be substituted for the cam plate 9 and in this case the blade is given two half revolutions and thus operates to effect a fold once in each revolution of its cylinder. The operation of the pins 17 is controlled by a cam 18 which tends to withdraw the pins 17 against the action of a spring 26 each time the following blade passes the rollers 3, 4. When the blades are set to fold once in two revolutions only the position of the preceding folding blade prevents withdrawal of one set of pins owing to the engagement of a lever arm 19 on the shaft which operates the pins with a projection on one side of the folding blade 6 of the preceding blade.
