Abstract: A process and a device for converting a periodic LF voltage into sound waves, or vice versa. The electro-acoustic transducer device has two groups of substantially parallel points which are separated by insulating screens. The points of each group are respectively connected to the positive terminal and to the negative terminal of a source of DC voltage, of the order of 10,000 volts, which renders the points emitters of an ion plasma. The DC voltage is modulated by a periodic LF voltage. The ion plasma oscillates and creates sound waves which analogically reproduce the LF voltage. This technology is particularly applicable to the construction of loud-speakers.

Abstract: COUPLING FOR LINED PIPE     ABSTRACT OF THE DISCLOSURE           Disclosed are coupling joints for interconnecting the ends of metal conduit sections having plastic liners to form a continuously lined conduit and methods for making such joints.          The opposed open ends of lined pipe are fitted with flanged end face collars which cover the end faces of the pipe and the open ends are then joined in an abutting relationship within a coupling sleeve by interference fit coupling.  The coupling sleeve carries an internal sealing band which mates with the outer edges of the opposed collars to fully seal the joint and the ends of the coupling sleeve are radially crimped into a corresponding groove in the pipe to mechanically interlock the joint.  Fully lined couplings are also formed by fitting an end face collar in the pin end of one lined conduit and interference fitting the pin end into an unlined bell on a lined conduit.

Abstract: ABSTRACT         Process for recovering minerals from mixtures containing the mineral particles and other particulate solid particles termed gangue, which process involves the attraction of the minerals to an oil phase containing an oleophilic collector leaving the gangue in the aqueous phase and removing the oil phase by passage through a special apertured oleophilic surface.  The pro-cess comprises:  (1) insuring that the mineral particles in the mixture have an oleophilic surface and such surface is sufficiently large to be attracted to other oleophilic surfaces, (2) passing the mixture containing the mineral particles and the other particulate solid particles through an apertured surface which is oleophilic so that the mineral particles are attracted to the said oleo-philic apertured surface and the other particulate solid particles pass through the apertures, and (3) removing the mineral particles from the aper-tured surface.

When a conventional electronic camera is used to inspect circular workpieces it is very difficult to analyse the output signal from the camera since it corresponds to chords taken across the work-piece (1).  To overcome this the present inspection system includes means (7) for scanning the image receiving surface in directions extending substantially radially across the image receiving surface to produce an output signal, and a signal analyser (12) arranged to monitor the output signal corresponding to each radial scan to detect the presence of any irregularity in the workpiece.

Granted: 1985-09-17
Abstract: ABSTRACT OF THE DISCLOSURE A hydro-pneumatic actuator for providing a two-stage buildup of the hydraulic output pressure.  A primary hydraul-ic piston, to which a pneumatic input piston actuator is con-nected, acts in a larger bore of a hydraulic cylinder to transfer fluid via a central passage in a spring-loaded, dif-ferential area, secondary hydraulic piston, that is coaxially disposed in the hydraulic cylinder in spaced-apart relation-ship with, and downstream of, the primary piston.  A larger face of the secondary piston is in the larger bore and the smaller face is in a reduced diameter bore of the hydraulic cylinder, so that a pressure buildup in the hydraulic cylinder effects actuation of the secondary piston to close a check valve and thereby inter-fluid communication between the larger and smaller bores of the hydraulic cylinder via the central passage.  The smaller face of the secondary piston is there-fore effective to transmit the hydraulic force with a high gain multiplication factor following attainment of an initial predetermined force with low gain.    The arrangement includes a displacement cylinder to meas-ure the pneumatic piston stroke and an expansion chamber into which fluid is drawn from the reservoir when piston stroke is excessive for subsequent transfer to the hydraulic cylinder.

Abstract: APPARATUS FOR CONTROLLING THE APPLICATION OF TELEPHONE LINE POWER IN A TELEPHONE SET            Abstract The present apparatus for controlling the application of telephone line power in a telephone set has obviated the requirement for a local source of power at the premises of a telephone customer.  A data processor-based telephone set incorporating the present invention comprises a power supply having first and second voltage storage devices which accumulate charge from the telephone line. First and second regulator circuits regulate the charging of the voltage storage devices and the power distribution to power-consumptive components of the telephone set during on-hook and off-hook switchhook conditions.  A voltage threshold detector actuates a power-down of power consumptive components including the data processor when the power supply voltage falls below a particular threshold value.  In the meantime, power is continuously provided to certain essential components such as the volatile memory of the data processor.  A telephone impedance switch under data processor control intentionally increases the resistance of the telephone set so that the telephone line voltage delivered to the telephone set is increased, the increased voltage powering certain components of the telephone which require the higher voltage level for proper operation.     ,    .    .    .
