Abstract: ABSTRACT OF THE DISCLOSURE           A rim is disclosed for converting a vehicle wheel into a dual wheel.  Different sizes of tires may be mounted on the rim, so that the rim may be used in con-nection with different vehicles having different sizes of tires without having to obtain a new dual rim  each time there is a change in the vehicle tire size.  The dual rim includes a cylindrical drum having a fixed rim element located adjacent to an outer peripheral edge of the drum.          An adjustable rim element is slidably located on the drum for axial movement away from or toward the fixed rim element, thereby accommodating different sizes of tires.  A plurality of hoop-like concentric retaining elements are attached to the drum outer surface and are axially spaced from the fixed rim element at predetermined intervals.  The adjustable rim element selectively engages one of the retaining elements depending upon the size of the tire used and the adjustable rim element is clamped in position.  Chain type releasable fasteners are connected between the drum inner surface and the vehicle wheel to releasably hold the dual rim in position.

Abstract: TERMINAL BLOCK MOUNTING FOR A PLUG-IN SURFACE HEATING UNIT                 ABSTRACT OF THE DISCLOSURE           A plug-in surface heating unit assembly for use in the cooktop of an electric range.  The heating unit is a metal sheathed electrical resistance heating element in spiral form with radial, outwardly directed terminal por-tions in close formation.  The invention relates to a folded spring blade which is fastened between a movable terminal block and the cooktop so that the spring normally biases the terminal block into an upward position while biasing the heating unit into a down position so that the unit will sit level with respect to the cooktop.  The termi-nal block is supported by means of a lost-motion connection from a fixed mounting bracket that is supported under the cooktop.

Abstract: ABSTRACT       A thin perforate, hellically wound welded edge tubing is used as a filter core for a roving wound filter.  The slightly roughened external edges of the spirally formed welded joint greatly adds to the ability of securing the fiber roving to the tube and prevents relative slippage there-between.   Also, the invention comprehends an apparatus for, and a method of making the helically seamed tube by first drawing a sheet metal from a supply and raising two lateral edges thereof to form flanges.  The material can be guided in a helical  path by engaging the inside of the flanges so that the trailing edge abuts the leading edge.  The abutted edges are heated so that the flanges themselves provide the filler for a weld on the exterior surface thereof.  Drive rollers are provided to move the welded tube from the welding area and to torque the tube to prevent edge separation prior to the cooling of the weld.

Abstract: ABSTRACT OF THE DISCLOSURE      This invention relates to electrical connection systems and more particularly to a connection system for connecting a cable to a thin metal contact plate in electrical connection with a patient.  In the medical electronics industry, it is common to secure a metal contact plate or foil onto a portion of a patient's body.          Previously, a clothing-type fastening button was utilized as a detachable connection between the foil and a cable connected to electronic instrumentation.  However, such a connection is undesirable since the fastener may unsnap when slight pressures are placed on the cable.  Also, this system allows for the connection of only a single conductor to the foil.  It is desirable to have contact redundancy by using a two-conductor cable which attaches at two different points to the foil to guard against intermittent electrical contact.  According to the present invention, a contact member having a tunnel section with contact pillars retained therein is connected to the thin metal plate.  The tunnel section has an oblong-shaped tunnel through which the contact pillars pass.  The contact pillars each have a staple-like attachment arm which extends below the tunnel section and through the metal plate.  These staple-like attachment arms are bent back against the metal plate to securely mount the contact member.  A cable connector connected to a two conductor cable is received within the tunnel for both mechanical support and electrical connection to the contact pillars.

Abstract: Abstract of the Disclosure Chemical and aqueous components of sludge derived from lime treatments of raw water supplies are recovered by procedures involving carbonation of the sludges to effect a phase separation between magnesium and calcium components. When the magnesium content of the raw water is intolerable in the treated water, a magnesium carbonate is recovered from the liquid phase by its decarbonation, and the aqueous component of the liquid phase is recycled to recover the water values of the treated sludge.  When the magnesium content of the raw water can be tolerated in the treated water, the liquid phase magnesium bicarbonate solution is recycled to the water treatment plant.  Turbidity factors separated with the sludges remain with the insoluble calcium carbonate that is separated from the liquid phase and by avoiding conventional coagulants other than magnesium hydroxide in the treatment of the raw water, turbidity and calcium carbonate components can be separated as by conventional forth flotation procedures to recover a quality line product. Special procedures are used in the carbonation step when flue gases are used for sludge carbonation purposes so as to avoid contamination of recovered lime with magnesium values and special procedures are advocated in the treatment of soft turbid water supplies as well as high magnesium turbid water supplies to avoid the necessity of disposal of environmental contaminating chemical flocculants ? ?? as alum.

Apparatus for generating such a field includes mutually orthogonal coils and circuitry for supplying an unmodulated carrier, hereafter called DC signal, to one coil and an AC modulated carrier signal, hereafter called AC signal, to at least one (usually two) other coil, such that the maximum intensity vector of a magnetic field produced by the currents in the coils nutates about a means axis called the pointing vector direction of the field.  The generated field is sensed in at least two orthogonal directions at the object to be tracked and whose orientation is to be de-termined.  The sensed signals provide an indication of the direction and orientation of the object relative to the coordinates of the generating means.
