Abstract: ABSTRACT The present invention relates to a method for comminuting a coarse lump of mineral material in an autogenous primary grinding system, in which an ingoing material is divided into a coarse fraction and a fine fraction which are determined by a crushing point determined by the point of intersection between two tangents drawn through two adjacent inflexion points on a size distribution graph obtained by screen analysis of a grinding mill charge of material obtained after an autogenous grinding process.  The smallest particle size of the coarse fraction is greater than the particle sizes in the upper of said inflexion points, and the ratio between said fractions is determined on the basis of achieving a given charge quantity for a particular, selected set-point power value for the mill in question, and determined with respect to a selected degree of grinding.

Abstract: ELECTRICAL CONNECTOR STRUCTURE AND METHOD OF MANUFACTURE     Abstract of the Disclosure An electrical connector includes an elongated contact portion extending from an anchor portion having a plurality of ribs or protrusions in an interference fit in a PCB plated through hole.  The plated through hole is tinned and air knife squeegeed before insertion of the anchor portion.  Thereafter it is fluxed via conduits defined by the periphery of the plated through hole and the ribs in the anchor portion. The electrical connector is soldered into the hole by solder reflow which in one example is accomplished by exposing the PCB to radiant energy within the infrared and visible spectrums.  The solder becomes concentrated, during reflow, into fillets adjacent the wall of the plated through hole and a terminating surface of each of the ribs such that solder contamination of the elongated contact portion is avoided.                           -i-

Abstract: PROCESS FOR THE AQUEOUS IMPREGNATION OF GREEN WOOD        WITH OIL-SOLUBLE METAL SALTS                   ABSTRACT OF THE DISCLOSURE A process for impregnating green wood with oil-soluble metal salts is described. The method comprises (a) contacting the green wood with an aqueous system com-prising (i) water, (ii) at least one oil-soluble metal salt of an organic carboxylic acid, and (iii) at least one surfactant for a period of time sufficient to enable the metal salt to penetrate into the wood, and (b) removing the wood from contact with the aqueous system. Good penetration of the metal salt into the green wood is realized by this method when conducted under vacuum, at atmospheric pressure or at elevated pressures. Preferably, the metal salt is a preservative such as fungicide, and the aqueous system also contains other desirable components such as fire retardants, coloring agents and insecticides.

The ad-vantage of an odd number of petals is that the interjoining seams, petal to petal, trace out one arm of a single parabola, are non-symmetrical with any other arm of a parabola and hence establish an interference pattern seam from seam, when 17 such seams exist tending to enhance the amount of electro-magnetic energy reflected onto the focus of the paraboloid of revolu-tion.   Higher gain and a better front to back ratio is achie-ved while also allowing simplicity of delivery from manufac-turer to user of a broken down paraboloid which can be assem-bled at site.

Abstract: ANGULAR POSITION DETECTOR            Abstract of the Disclosure A transducer formed of one or more electrode arrays is positioned in confronting relation and parallel to the plane of rotation of one or more rotating members.  A plurality of phase modulated, two-phase, square wave drive signals of the same amplitude and frequency are applied to each electrode. The signals are combined at a central node or electrode to form, as a result of the signal, the superposition of the algebraic sum of all drive signal pairs.  Samples of the resultant signal taken at the same frequency and of a duration of less than one-half the duration of the drive signal period provide a multi-step, synchronously detected signal.  The detected signal is a multi-step approximation to a sine wave, the phase angle thereof relative to a timing point being proportional to the angular position of the rotating member.  The amplitudes and phase shifts of the multi-step detected signal are then reduced to a plurality of vectors, from which two orthogonal vectors are produced which may be mathematically reduced to the amplitude and phase angle of the aforesaid sine wave.  The phase angle is transformed or converted into a binary representation of the hand position. The amplitude of the sine wave is utilized in conjunction with a stored look-up table to generate a binary compensation value for the aforesaid binary representation, which compensation is representative of a variance in the detected signal as a result of the distance between the transducer and the rotating member. A second binary interdial compensation value is generated to correct for errors in the mechanical misalignments of certain ones of the rotating members which would normally lead to ambiguities in the dial readings.  The entire procedure is con-trolled by a unique program which incorporates a special numerical code which ultimately provides an output signal that is the BCD equivalent of the integer value representative of the position of the rotating member.

Abstract: ABSTRACT:            A voltage-controlled oscillator having an elec-trical means of frequency control which is able to operate from a supply voltage which is lower than is desirable to use with a varicap diode.  The circuit is a modified Colpitt's oscillator.  The oscillator comprises a pair of transistors whose base and collector electrodes are con-nected together, the base electrodes being connected to a supply rail (+Vcc) and the collector electrodes are con-nected to a tunable parallel LC resonant circuit.  A fre-quency determining device e.g. a crystal is connected between a tapping of the resonant circuit and the emitter of one of the transistors to form a first feedback path. The crystal together with an integratable small value capacitor connected between the emitters of the transis-tors form a second feedback path.  The phase shifts due to the first and second feedback paths are summed vectorially at the collectors of the two transistors.  By varying the gain of each of the two transistors then the resultant phase shift, and thereby the frequency of oscillation, are varied.
