Abstract: PORTABLE TRACTION APPARATUS     Abstract of the Disclosure A portable apparatus for elevating in traction the hips of a person.  A pair of vertically oriented, tri-angular shaped side frames, adapted for placement upon the top of a bed, support a horizontally oriented, elongate cross beam above the hips of the user.  The user's hips are suspended at a selected elevation beneath the cross beam by a cord attached at one end to a conventional traction belt worn by the user and, at its other end, threaded through a pulley suspended by a hanger from the cross beam, and attached to a convenient anchor.  The cross beam is releasably attached to the two side frames by a pair of respective clamps which permit the position of the frames along the longitudinal axis of the cross beam to be varied for adjustment of the distance between the two frames.  The hanger utilizes a sleeve placed over the cross beam so that it may slideably move along the longitudinal axis thereof, and the pulley is attached to the hanger by a pair of flexibly interlinked rings permitting the pulley to move freely relative to the hanger to maximize the comfort of the user.  A pair of slotted tabs may be fixedly attached to the pulley for anchoring the upper end of the cord by wedging it into the slot of one of the tabs.

Abstract: ABSTRACT OF THE DISCLOSURE            The method comprises processing of the slime and off-gases resulting from the production of phosphorus by an aqueous solution of copper sulphate preferably at a concentra-tion of from 15 to 50% by weight.  The process is preferably conducted at a temperature within the range of from 20 to 80°C to give two products, i.e. solid and liquid ones.  The solid product containing mainly copper phosphide as well as fluorides, chlorides of alkali metals and silicon, calcium and aluminium silicates is used as a modifying and refining agent for hypereutectic silumines as well as for the production of a copper-phosphorus alloy.  The liquid product containing phosphoric acid, sulphuric acid, and copper sulphate serves as the starting material for the manufacture of a copper-containing fertilizer therefrom.  The method according to the present invention makes it possible to improve the production of phosphorus so as to eliminate the formation of secondary wastes and thereby contribute to a better control of the environment protection.

Abstract: ABSTRACT OF THE DISCLOSURE           A method is provided for transferring a charged particulate image such as a xerographic image across gaps between electrodes where the electrode spacing is much greater than heretofore employed.  Thus, envelopes containing bulky objects such as keys, novelties and the like, can be addressed by xerographically forming a particulate image in the conventional manner and transferring it in accordance with the invention.          In accordance with the invention, a charged particulate image is deposited on a non-absorbent dielectric transfer sheet and transferred to an absorbent receiver sheet by placing the transfer sheet and receiver sheet between a pair of electrodes having a potential difference sufficient to transfer the charged particulate image, one of the electrodes being a pointed electrode positioned behind the transfer sheet having an emitting angle of between 0° and about 90° so as to provide high fields at the emitting end of said electrode and the second electrode being a blunt electrode positioned behind the receiver sheet having an emitting angle of between about 90° and 180° so as to provide low fields at the emitting surface of said electrode.

The structure includes a tillage blade or cutter wheel mounted for rotation by a drive structure that includes a rotatable drive shaft.  The cutter wheel has a thin disc-like body portion and a periphery with a plurality of teeth thereon, with different teeth being offset in opposite directions from the plane of the body portion.  The offset teeth which in a preferred embodiment have hard-facing on the cutting surface, have a specific configuration to allow the cutting wheel to produce a furrow in ground contacted by the wheel, with the furrow being wider than the body portion of the wheel due to the offset teeth, and this results in reduced soil compaction at the bottom of the furrow, as well as loose dirt therein to provide cover for seed deposited in the furrow.  The drive structure includes a friction drive plate for rotating the cutter wheel, with the cutter wheel being fastened to the threaded drive shaft so that the cutter wheel is self-tightening.

Abstract: Abstract of the Disclosure:      In a process for preparing polymethylene polyphenyl polycarbamates by reacting an N-phenyl carbamic acid ester with formaldehyde or a formaldehyde-producing compound in the presence of an acid catalyst, the use of an acid having an acid dissocia-tion constant (Ka) of not less than 1.25 x 10 7 in acetic acid at 25°C brings about an enhanced reaction rate as compared with those which have been attainable by prior art processes.  For example, when an N-phenyl carbamic acid ester is reacted with a 35% aqueous solution of formaldehyde in the presence of trifluoromethane-sulfonic acid, the reaction rate is greatly enhanced as compared with the cases in which prior art acid catalysts such as sulfuric acid, hydrochloric acid, etc. are used.
