Abstract: ABSTRACT OF THE DISCLOSURE        Methods and apparatus for making electrical circuits on a non-conductive plate are disclosed.  The invention provides for duplication of a circuit pattern on an insulating plate carrying a continuous deposit of electrically conductive material by a mechanical linkage between a milling device which removes the conductive deposit and a scanning device which is moved in accordance with a master pattern.  In preferred embodiments the movement of both devices is confined to one of two or sometimes three co-ordinates for a particular portion of the pattern.  The method is swift and efficient, and the invention is equally applicable to small or large-scale manufacture, although it is of especial value where small numbers of circuits are to be produced.

Abstract: CONTINUOUS PRODUCTION OF 2,5-DIOXO-1-OXA-2-PHOSPHOLANES.                     ABSTRACT OF THE DISCLOSURE: Continuous production of 2,5-dioxo-1-oxa-2-phospholanes of the general formula   from a beta-halogenoformyl-ethyl phosphinic acid halide of the general formula R1XP(O)-CHR2-CHR3-CO-X in which formulae R1 stands for an alkyl radical having 1, 2, 3 or 4 carbon atoms, or a phenyl radical, R2 and R3 each stands for hydrogen or CH3, and X stands for chlorine or bromine, by reacting the said acid halide with acetic anhydride.  The phospholanes are produced by introduc-ing, into a heatable circulation reactor, an initial quantity of the desired 2,5-dioxo-1-oxa-2-phospholane and circulating it therein at a temperature of 110 to 190°C; separately preheating the respective beta-halogenoformyl-ethyl phosphinic acid halide and acetic anhydride starting materials to a temperature of 60 to 160°C; mixing these starting materials together and continuously adding the resulting mixture to the material circulated in the reactor, the mixture being introduced into the lower third of the reactor; distilling off resulting acetyl halide near the head of the circulation reactor, a pressure difference of 0.1 to 5 bar, being established between the point of introduction of the mixture of starting materials and the overflow level in the circulation reactor, and the material being kept circulating by the evaporating acetyl halide; and removing the resulting desired 2,5-dioxo-1-oxa-2-phospholane from the reactor at a location which is below that at which the acetyl halide is distilled off.

Abstract: Abstract of the Disclosure Matable electrical connector means having an "inertia" lock with a self reject feature comprise first and second connector bodies respectively retaining matable male and female terminals having a predetermined terminal engage force.  The connector bodies include a deflectable latch arm and generally triangular lock ramp respectively which cooperate to lock the connector bodies together and retain the terminals in a fully mated position.  During assembly, the latch arms are deflected outwardly, by the leading portion of the triangular ramps pro-ducing a force which resists connection of the connector bodies. This latter resistance force reaches a maximum magnitude of about twice the terminal engage force when the latch arms engage the peaks of the ramps.  The terminals do not engage in a way which produces any appreciable resistance force prior to the latch arms passing the peaks whereupon the latch arms produce a force assisting locking of the connector bodies together.

Abstract: ABSTRACT:             Apparatus for reading a record carrier on which a television signal is recorded.  In order to ensure an accurate time error measurement for a time error correction device, use is made of a burst sig-nal which is locked to the horizontal synchronizing pulses.  Said burst signal may be constituted by the colour burst signal or an additional burst signal which is superimposed on the horizontal synchroniz-ing pulse.  In order to obtain a pilot signal for the time error measurement a keying signal is generated with the aid of a generator which is controlled by the horizontal synchronizing pulses, the beginning of said keying signal situated within the time interval of the burst signal.  The first zero passage of the burst signal which appears after the beginning of said keying signal is employed as pilot signal for the time error measurement.  In  order to increase the reliability of the system an automatic correction system is provided which ensures that the beginning of the keying signal lies halfway between two conse-cutive zero passages of the burst signal.

Abstract: ABSTRACT OF THE DISCLOSURE   1,3-Diaryl triazenes, e.g., 1,3-diphenyltriazene, intermediates in the synthesis of aromatic diamines, e.g., p-phenylenediamine, are prepared by catalytically oxidizing ammonia, and subsequently the resulting nitric oxide, with a gas comprising diluted molecular oxygen, e.g., air, so as to produce a gas mixture containing dilute NOx, i.e., NO2 prefer-ably admixed with NO, a being (1 + n), wherein n is the NO2 fraction of the NOx; and contacting the gas mixture, prefer-ably at a temperature in the range of about from 25° to 350°C, with excess primary aromatic monoamine, e.g., aniline, so as to result in a monomamine temperature in the range of about from 25° to 90°C, preferably 40° to 60°C, during contact. Highest yields of triazene are obtained when the x in NOx is about from 1.3 to 1.7, and the amount of NOx gas mixture con-tacted with the monoamine and the time of contact are such that at least about 60% by weight of the monoamine remains unconsumed.  A gas mixture temperature just prior to gas con-tact with the liquid monoamine in the range of about from 110° to 275°C is more preferred under certain circumstances.

Abstract: THREADING DEVICE          Abstract of the Disclosure The specification discloses a die casting machine of the type adapted to form an article with an internal threaded portion.  The threaded portion is formed by means of a threading device which is retractable.  The threading device is rotatably and retractably operated by a pinion which in turn is rotated by a cog wheel.  The die casting machine may contain a plurality of molding cavities, each being provided with the threading device.  The cog wheels may be driven by a common rack which is hydraulically operated.  Since the threading device of this invention is retractable, it is feasible to repeat a casting cycle without replacing the mold.  Thus, it is much faster to fabricate such articles with the present machine than conventional die casting threading apparatus. Because no part is replaced or removed from the die casting machine in the present invention, it is possible to minimize possible dimensional variation among the articles fabricated. The specification also discloses a method for forming die casting including internal threaded portions by using the die casting machine according to the present invention.

Abstract: ABSTRACT      The invention provides for a floating island for producing power from tides.  The floating island is comprised of a column fixed to the ocean bed, and a float interconnected to the column.     The up and down motion of the float relative to the column, in response to tide motion is translated into power by force linking means, and electrical generating means convert this power into useful electricity.  Suitable force linking means may be comprised of pulley gear mechanisms, helical drive mechanisms, rack and pinion mechanism, induction mechanisms, and hydraulic mechanisms.  The float is interconnected to the column by gimbal mounting means.  The gimbal mounting means allow the float to tilt in relation to the wave motion, while still permitting the tide motion to move the float up and down and produce power.  The apparatus referred to may be provided as one or a number of units.
