Title: Single unit delayed coking and calcining process
IPC: C10B55/00
Filed: 1967-04-21
Abstract: Coke made in a drum by the delayed coking process from petroleum hydrocarbons is calcined in situ in the drum by igniting the coke at one point and introducing oxygen (air) at a point on the other side of the combustion front formed in the ignited coke. The drum, suitably insulated to withstand calcining temperatures of up to 2800 F., has an outlet at the top for combustion gases, which may be recycled to an air inlet at the bottom of the drum to control the temperature in the combustion front, which moves down the drum. Two fronts may be established, one at the top and one at the bottom, the air being supplied between them, and automatic control systems responsive to drum temperature may regulate the supply of oxygen to the drum.

Title: Recovery of residual product in hydrocarbon oxidation process
IPC: C07C29/52
Filed: 1968-01-17
Abstract: A process for the partial oxidation of a hydrocarbon with molecular oxygen in the presence of a boron comopund comprises hydrolysing the effluent from the oxidation, which contains unreacted hydrocarbon and borate esters of the corresponding alcohol, with water to form an organic phase containing unreacted hydrocarbon and the bulk of the alcohol and an aqueous phase containing the boron compound and the residual amount of the alcohol, passing the organic phase to a distillation zone operated at pressure to separate the unreacted hydrocarbon from the bulk of the alcohol and steamstripping a portion of the aqueous phase in a stripping zone under pressure and passing the vapours obtained to said distillation zone, thereby separating the residual amount of the alcohol along with the bulk of the alcohol. Suitable reactants are saturated C 4-20 hydrocarbons, particularly cyclohexane, the preparation of which is exemplified. The corresponding ketone is formed as a by-product of the oxidation and is recovered with the bulk of the alcohol from the organic phase after hydrolysis.

Filed: 1968-04-11
Abstract: In a dry-cleaning apparatus as described in Specification 1,229,845 the condenser 26 is connected to the upper part of tank 11 as well as to container 1 so that solvent may be returned to either during regeneration of the solvent. The solvent recovery circuit comprises an electric fan which sucks air from inlet 20 over a heater 19 and feeds it through tank 11, tube 24 and filter 25 to condenser 26. The condensate passes through tube 27 and inspection point 28 to separator 29 connected directly to tank 11 and through a valve 30 to container 1. Inlet 20 is closed and cycling is continued in a closed circuit until no appreciable flow passes point 28. Fan 22 then discharges any remaining vapours through an outlet 33. The refrigeration unit 34 of condenser 26 is arranged in series with the refrigeration unit 36 of condenser 37 connected to still 40 which is connected to the drain of filter 9. In operation, when cleaning is completed, pump 5 stops, the solvent drains from container 11 and the garments &c are centrifuged after which drying takes place. Final deodorization is carried out with air drawn in from outside and heated. The whole of the solvent may be regenerated by distillation using tank 11 as a temporary storage tank.

Crank arms 42, 43 carry pairs of cam followers, crank arm 42 being associated with cam followers 38, 39, and are fixedly mounted on a crank shaft 48. Each crank arm drives a leg of the figure up and down. The head of the figure is moved from side to side by means of the movement of a vertical rod, the horizontal portion 49 of which is attached to crank arm 43 by a bracket 50. The legs of the figure are pivoted at the knee and are moved up and down alternately. Each foot is attached to a pedal of the vehicle, the pedals being fixed on axles 98, 103. Up and down movement of the pedals drives forward the wheel 65 which is supported on an axle 62, by means of a ratchet and pawl arrangement. The pedal support member 96 is attached to a disc 79 which has extending from it a disc 85 on which is pivotally mounted a pawl 89. When the pedal is moved downwards the pawl end is held in connection with the ratchet wheel 75 by a biassing spring 92, driving the vehicle forwards. At the same time, the pawl end 78 of the other pedal, which is being raised, is disconnected from the ratchet wheel 74. In a modification, the vehicle comprises a wheeled hobby horse, which is driven along the ground by direct engagement between the ground and the ball portion of the feet of the figure.

Patent ES-397069-A1 (ES)
Title: Synchronous detector control
IPC: H03G3/30
Filed: 1971-11-16
Abstract: A synchronous detector includes a differential amplifier section formed from two transistors with input signals applied to their base electrodes and output signals taken from their collector electrodes for application to an included synchronous switching section. A current source section is also included to supply substantially constant quiescent current to each of the transistor emitter electrodes, while a control section is additionally included for diverting some of this current away from the differential amplifier transistors when it is desired to reduce the gain of the detector or inhibit its operation. The electrical control section, however, re-inserts the diverted current into the switching section at a point such that the direct output voltage of the detector does not change as the gain is reduced or as its operation is inhibited.

Patent ES-434260-A1 (ES)
Title: Audio frequency squelch system
IPC: H03G3/34
Filed: 1975-01-29
Abstract: An audio frequency squelch circuit responsive to a signal including voice signals in the presence of noise includes a limiter for receiving the signal and a monostable multivibrator coupled to the limiter and triggered by negative (or positive) transitions in the limiter output. The multivibrator produces pulses of fixed amplitude and time duration to provide an output wave having a duty cycle which varies with frequency. The pulse wave is passed through a low pass filter having a bandwidth sufficiently wide to allow coherent variations in frequency at a voice syllabic rate, and which removes random noise inputs, with opposite phases being applied to high pass filters which reject signals varying slowly in frequency. The opposite phase signals are applied separately to comparators operating against a fixed voltage reference, one of which provides an output in response to voice frequency peaks which are sufficiently above the mean frequency and the other provides an output in response to voice frequency peaks which are sufficiently below the mean frequency. The comparator outputs are applied to an OR gate which controls an integrator and timer to actuate the squelch.
