Title: Electrolytic production of sodium persulfate
Inventor: RADIMER KENNETH J
IPC: C25B1/28
Filed: 1977-11-29
Granted: 1980-11-25
Abstract: ABSTRACT:    Preparation of sodium persulfate in an electrolytic cell having a protected cathode is obtained by the direct electrolysis of aqueous anolyte solution in which there is initially dissolved a sufficient amount of a mixture of sulfates and peroxydisulfates of sodium and ammonium to provide an anolyte feed solution containing by weight 5 to 9% sodium ions, 12 to 30% sulfate ions, 1 to 4% ammonium ions, an effective amount of a polarizer, and optionally up to 20% peroxydisulfate ions.  The cell catholyte is a sulfuric acid solution, which may contain Na+  and NH? values, and the electric current density is at least 0.5 amperes per square centimeter of platinum surf ace of the anode.

Abstract: ABSTRACT OF THE DISCLOSURE     This invention relates to a method of forming a composite article of shaped metal and moulded synthetic plastics material, comprising disposing a metal blank in a closable injection mould adapted to receive a metal blank, the said mould being provided with means whereby the metal blank may be shaped, cut or shaped and cut; introducing mouldable synthetic plastics material into the mould; and simultaneously with the shaping or cutting of the metal blank by the said shaping or cutting means the mouldable plastics material in the mould is moulded onto the metal blank to form a shaped and moulded composite article.  The present invention is Bassett upon an idea of applying the fact that the mold part of a usual injection molting apparatus can be utilized also as a press molding machine, and the fact of carrying out the press processing step which is most often employed to process hard materials, at the time of shaping synthetic resins.   As a result, the simplicity of steps ant improvement in the accuracy are attained to a great extent and reduction in the percentage of rejection is achieved when compared to the known two-step metal insert method.

Abstract: ABSTRACT OF DISCLOSURE            The invention refers to a card index, preferably a telephone subscriber's index, including a flat casing having a top, side walls and a front opening, a tray adapted to be pushed into and pulled out of this casing through said opening, and a pile of index cards supported on the tray and intended to have information, such as telephone numbers, accounts etc., written down thereon. The index is furthermore provided with manually operable means in the form of depressible keys with dogs provided on the underside of the keys for determining, before pulling out the tray, which index card is to be presented to an operator by depression of an optionally selected one of said keys so as to cause the dog thereof to bend down the front portion of a number of said index cards and thereby at the same time to urge the remaining cards lying thereabove into engagement with the inside of the top of the casing, where they are retained in position, when the tray is pulled out together with the bent-down cards, by depending catch members on the casing top at the front end thereof. An upright bar is provided on the tray in front of the front edges of the index cards to bring the bent-down cards back together with the tray when pushing in the latter into the casing.

Abstract: Abstract of the Disclosure Sheet Dispenser A sheet dispenser for dispensing sheets one at a time from a stack of notched photographic X-ray film sheets. The essential part of this device is a pendulum which is capable of swinging from side to side across the sheets, which are stacked at a slight angle to the vertical, and also back and forth in the plane of the thickness of the sheet stack. The pendulum is made from a roller which has a plough release member attached to it. When the pendulum is moved side ways until it is in line with the notch on the uppermost sheet the release member locates into the notch, and, as the sideways movement continues, ploughs under the sheet and detaches it, allowing it to fall under the action of gravity. The pendulum then moves sideways in the opposite direction, remaining in contact with the next sheet, until the release member locates into the notch on the next sheet whereupon the plough detaching operation is repeated.

Abstract: ABSTRACT OF THE DISCLOSURE           An improvement in an inductive repulsion type vehicle magnetic levitation and guide system for a curved track in which the vehicle is levitated by an electro-magnetic force generated between levitation conductors having the same time constant and laid in two parallel rows on the ground at specific intervals in the direction of travel of the vehicle and levitation superconductive magnets on the vehicle capable of being electromagnetic-ally coupled with the levitation conductors, the magnets being opposed to the levitation conductors at a specific distance from the Levitation conductors.  The vehicle is guided by an electromagnetic force generated between guide conductors having the same time constant successively positioned at specific intervals in the direction of travel of the vehicle and guide superconductive magnets mounted on the vehicle opposed to the guide conductors at a specific distance from the guide conductors.  The electro-magnetic force generated between the levitation super-conductive magnets and the levitation conductors or between the guide superconductive magnet and the guide conductor on  one side of a curved track is made larger than the similar force generated on the other side of the curved tracks, and the differential force counteracts the centrifugal force acting on the vehicle running over the curved track, thus stabilizing the vehicle running at high speed along the curved track.
