Abstract: METHOD OF PREPARING  "-Al2O3 Abstract of the Disclosure .beta."-Al2O3 is a highly desirable material for serving the double function of solid electrolyte and separator in a re-chargeable battery that employs sodium, Na, as the anode and sulfur, S, as the cathode.  But conventional means for manufacturing the .beta."-Al2O3 require temperatures between 1400 and 1600°C.  By reacting .theta.-Al2O3 with Na2O, or a compound that yields Na2O on decomposition, the desired .beta."-Al2O3 is obtained at temperatures as low as 950°C.

Title: Electrical control devices

Abstract: ABSTRACT OF THE DISCLOSURE An electrical control device comprises a base member, and an elongate support member mounted to be movable transversely of its length with respect to the base member and biased against movement in one direction transversely of its length and towards a null position.  An elongate resistive member extends along the length of the support member, and when the ends of the resistive member are connected to oppo-site poles of a voltage source a sensing electrode can be applied to the resistive member to tap off a voltage which is selectively variable by varying the position along the support member at which the sensing electrode is applied to the resistive member.  Application of the sensing electrode to the resistive member tends to bring about movement of the elongate member with respect to the base member in opposition to the bias on the elongate member.  A position pick-ups has a first part connected to the support member and a second part connected to the base member, and generates an electri-cal analog signal dependent on the position of the support member with respect to the base member.

Abstract: ABSTRACT OF THE DISCLOSURE            A method for the manufacture from low carbon steel of rims for the wheels of both commercial load carrying and passenger service vehicles.  Each rim is composed of a base portion having a gutter for receiving a split lock ring extending around one end and a fixed tire bead retaining flange around the other end.  The method comprises bending a steel strip of substantially uniform predetermined thickness into the form of a circle and butt welding the contiguous axial edges to form a cylinder.  The cylinder is cold worked in order to conform the diameter and dimensions thereof to subsequent operational requirements and simultaneously to flare one end of the cylinder to form the rim gutter.  The flared gutter portion is heated and the heated portion is subjected to compressive load in order to form the vertical wall of the gutter flange and increase the thickness of both the wall and the radial corner of the gutter.  The semi-formed rim is cold worked in order to form the profile of the gutter and simultaneously to flare the opposite end of the cylinder to form the tire bead retaining flange.  Finally, the flared flange portion ?s subjected to compressive load in order to form the profile of the flange.

Abstract: ROGERS, BERSKIN & PARR                    CANADA    ABSTRACT OF THE DISCLOSURE:             An electronic filter for use in determining the position of a body travelling through water relative to a datum such as means sea level, and having specific application to underwater seismic systems that produce profiles of the terrain beneath bodies of water. The filter is connected to an accelerometer and a pressure transducer,  physically located within the body, that respectively produce an acceleration signal indicative of the body's vertical acceleration and a pressure signal indicative of the body's vertical displacement with respect to the datum. The filter combines the acceleration and pressure signals to effectively isolate a signal propor-tional to noise generated by the pressure transducer. The filter then combines the signal so isolated with the pressure trans-ducer signal to produce a vertical displacement signal relatively free from noise. The filter is used in association with apparatus that produces a correction signal that approximates accelerometer signal components corresponding to the effect of gravity on the accelerometer. The filter combines the correction signal with the acceleration signal to attenuate noise components in the filter output signal that correspond to the gravity effects.

Abstract: PRESSURE WELDING METAL BARS TOGETHER                   ABSTRACT OF THE DISCLOSURE     A process for pressure welding two metal bars together by their ends comprises bringing together the ends to be welded with these ends in a wedge-shaped form and at a temperature between the melting temperature and 450 degrees C below the melting temperature.  The ends are pressed together in the longitudinal direction of the bars so that the ends penetrate into each other, with the edges of the wedges in crossing relationship.  The ends are continuously pressed into each other until substantially all of the surface material of both wedges is expelled from the cross-sectional shape of the welded bars.  The process has the advantage that it is a continuous process, while exhibiting a reduced risk of buckling.  The process can be adapted to the continuous production of copper wire rods in an in-line plant.
