Abstract: Abstract of the Disclosure Ethylbenzene is prepared by the reaction of ethylene and benzene in the presence of a Friedel-Crafts aluminum chloride catalyst complex, in a process in which the ethylene is initially dissolved in the benzene, prior to contacting with the catalyst.  By eliminating the gaseous phase from the reaction it permits the use of a plug flow reactor.  As a result, a process is obtained which proceeds in the kinetic region, using much smaller quantities of the Friedel-Crafts catalyst, to produce in short time the desired product, with significantly reduced amounts of byproducts.

Abstract: ABSTRACT     An electrical connector comprises an insulating housing having a wire receiving face into which a cavity extends.  A sheet metal terminal is disposed in the cavity and has a slotted plate type wire connecting portion adjacent to the wire receiving face.  The wire connecting portion comprises an elongate metal strip which has been reversely curled inwardly to form an arcuate surface adjacent to the wire receiving face and a free end which is spaced from an intermediate portion of the terminal.  A wire receiving slot extends into the strip at the free end and a wire receiving opening is provided in the strip adjacent to the wire receiving face.  In use, a wire is inserted axially through the opening so that the end of the wire is located between the free end of the strip and the intermediate portion of the terminal.  The wire connecting portion is then subjected to a force applied against the cylindrical portion of the terminal which causes the wire connecting portion to be further curled.          Such curling causes the free end to move past the wire so that the slot receives the wire and establishes electrical contact therewith.

Granted: 1985-04-02
Abstract: Electrolysis of an alkali metal chloride solution is carried out in a cell having the anode and the cathode surfaces in contact with the surfaces of an ion exchange membrane. The electrolysis is performed at a lower voltage than in conventional cells and the alkali metal chloride contact of the alkali hydroxide product is markedly reduced. In the case of a finger type cell, alkali metal chloride impurity in the cell liquor is lowered particularly effectively by maintaining the ratio of the effective area of ration exchange membrane to that of the anode at 1.1 or less. The invention enables the widely-used asbestos or modified asbestos diaphragms in electrolytic cells to be replaced by ion exchange membrane cells so that the quality of the products is not only enchanced but the serious problem of environmental pollution due to asbestos losses from such cells is eliminated.

Abstract: ABSTRACT OF THE DISCLOSURE          A shelf box is designed for use with a shelf rack or storage cabinet open on both sides so that the shelf box can be removed from either side of the rack or cabinet.  Two stop members are respectively mounted adjacent to opposite ends of the shelf box for pivotal movement between stop and release positions, and are interconnected by a pivoting linkage so that when one stop member is in its stop position the other stop member is in its release position.  The stop members are disposed so that in their stop positions they are engageable with retaining portions of the overlying shelf. Thus, when one end of the shelf box is withdrawn from the rack or cabinet it will be stopped by engagement of the adjacent shelf retaining portion with the stop member at the opposite end of the shelf box in its stop position to prevent inadvertent complete removal of the shelf box.  If the stop member adjacent to the end being withdrawn is in the stop position it will engage the adjacent shelf retaining portion for cammed movement of the stop member to its release position, thereby simultaneously moving the stop member at the opposite end of the shelf box to its stop position.  The linkage intercon-necting the stop members provides bearing surfaces for non snagging sliding of side-by-side shelf boxes with respect to each other.

Abstract: ABSTRACT    This invention relates to a device for sensing moisture on a metal surface such as a brake path.     Since the presence of moisture on a brake path causes inefficient working of the brake, it is necessary to test for moisture.  Originally this was done by hand. The present invention provides a device which can test for moisture automatically.  The device comprises a pair of contacts urged against an electrically conduct-ing surface.  One contact is covered by a strip of material, for instance paper, which is an insulator when dry and a conductor when moist.  If moisture is present an electrical circuit comprising the surface, the moist material and the two contacts is completed activating an alarm.  The material may be salt impreg-nated and the contacts may be moveable over the surface.     The device is for use in testing for moisture on the braking surfaces of colliery winding installations.

Abstract: Abstract of the Disclosure The subject of the invention is a seal for the gap between a revolving shaft and a housing bore.  At low rotational speeds and at standstill, an annular, spring-loaded packing lip of elastomeric material provides the sealing effect.  With increas-ing speed, the pressure of the packing lip against the counter-face is reduced by the centrifugal force and the sealing effect is shifted to a dynamic sealing flange.  The latter revolves with the shaft and its end face is in sliding contact with a stationary surface facing in the direction of the medium to be sealed off.  The flange has holes that permeate it completely in radial and axial direction and that are interconnected.  The flange is made from an internally cemented granulate, or from fibres or plates.  The sealing effect results from the fact that the medium to be sealed off, after penetrating the wetted surfaces of the flange, is deflected by the effective centrifugal force towards the outer perimeter and is returned cyclically to the sealed space.  The components of the medium that have lower speci-fic gravity, preferably air contained in the medium, at the same time effect a continuous removal of heat, a lubrication and a dynamic sealing of the end face of the flange and the stationary radial surface that slide one over the other.
