Abstract: COLOURED PATTERN ON ANODIZED          ALUMINIUM ARTICLE WITH SHAPE DIFFERENCE                Abstract of the Disclosure The specification relates to a method of forming a colored pattern on an article made of aluminum or alumi-num alloy.  The article is first anodically oxidised at a voltage from 10 to 120 volts to form a barrier layer.          The barrier layer is then increased in thickness on those areas which, in the finished article, are to be colored by subjecting those areas to a second anodic oxidation at a voltage of from 15-200 volts, but at least 5 volts greater than the voltage applied in the first anodic oxidation.          The article is electrolytically colored in an electrolytic metal salt bath at a voltage of from 5-75 volts either before or after the barrier layer formation.  In this way a colored pattern can be formed on the article without the step of coloring the whole of the article uniformly, so the resulting pattern can be graduated in color or have partially colorless portions.

Abstract: ABSTRACT OF THE DISCLOSURE    A transmission control apparatus for a vehicle having a transmis-sion with fluid actuated clutch means and hydraulic brake means wherein a first fluid conduit, having a fluid flow constricting means interposed therein, connects a fluid pressure source with the clutch means, with an inching valve means being fluidically connected in parallel with the first conduit by second and third conduits upstream and downstream respectively, from the fluid flow constricting means, for regulating the pressure of the pressure fluid supplied to the clutch means, with the inching valve means also being operatively connected with the brake means and responsive to the degree of actuation of the brake means and actuatable between a first and a second position. whereby in the first position, the pressure fluid can freely flow into, through and out of the inching valve toward the clutch means so as to effectively bypass the fluid flow constricting means. however in the second position, the fluid flow through the second conduit is blocked off and the flow of fluid toward the clutch means is forced to flow solely through the fluid flow constricting means. thereby keeping the clutch means filled with fluid at all times.  A further conduit connects the pressure fluid with the clutch means for lubrication and cooling purposes, with the fluid flow constricting means, in the second position functioning to lower the fluid flow through the first conduit so as to increase the amount of fluid flow into the further fluid conduit.

Abstract: RICHARD B. REICH                    HEAVY FUEL OIL NOZZLE                     ABSTRACT OF THE DISCLOSURE            An atomizing nozzle particularly suited for your use in compact combustion chambers.  Successful combusition of liquid fuels having generally high viscosity and widely varying properties such as distillation temperatures, distillation rates and impurities, including "heavy" and waste oil.  Improved combustion is accomplished through the use of viscosity control and improved fuel atomization.  Use of a nozzle utilizing "shearing" of the fuel by an atomizing fluid stream which inter-sects the fuel at approximately right angles.  Recombination of liquid fuel particles is prevented by the use of a controlled "exit orifice" in the burner nozzle.  The nozzle also features continuous circulation of the fuel in the nozzle body which establishes orientation of impurities contained in the fuel relative to the exit orifice so that they are expelled through the orifice.  Combustion of conventional distillate fuel oil such as API No. 1 and 2 is also provided.

Abstract: ABSTRACT OF THE DISCLOSURE     System for recovering oil products from oil sands in which super-heated steam from a nuclear reactor is mixed with water in a chamber under high superatmospheric pressure to obtain hot water at a temperature near the boiling point at the prevailing pressure.  The hot water enters a reaction tube which has an input extruder for feeding oil sands into the reaction tube in contact with the hot water to effect release of the oil from the sands.  The outlet of the reaction tube opens into a hydrocyclone into which the reaction products of oil and sand and water are discharged.  An extruder at the bottom of the hydrocyclone discharges separated sand and some water which passes into a settling tank to settle the sand and the clarified water filtered and returned to the pressure chamber.  The separated oil together with some water from the hydrocyclone flows to an oil separator where the oil separates from the water, which latter is also returned to the pressure chamber.  The oil may be separated into fractions in a fractionating column and the column bottoms may be hydrogenated and returned to the fractionating column.  Better oil recovery from the oil sand can be achieved and more efficient operation attained.

Abstract: DIGITAL MEASUREMENT OF THE DC VALUE IN       AN AC SIGNAL ADAPTED TO TELEPHONE OFF-HOOK DETECTION                 Abstract of the Disclosure The duty cycle of an AC telephone off-hook signal is measured by means of comparing it with the duty cycle of a known AC signal having a duty cycle of 0.5 because it has a DC component of zero.         Measurement of the duty cycle in a telephone off-hook detector application involves measuring the DC portion of the signal on a pair of telephone lines from a telephone handset to an exchange.  A high frequency master clock oscillator with a much higher frequency than the basic ringing voltage is used.  An input signal is used to gate clock pulses when the input signal is positive to a counter.  At the end of a predetermined number of clock pulses, the counter is gated into memory connected to a decoder for transmission of the decoded signal to the exchange for appropriate action.
