Abstract: ABSTRACT OF THE DISCLOSURE             A pressure source for providing a stream of liquid at a sub-stantial pressure,  The pressure source includes pressurizing means such as a piston-cylinder assembly to which a force is applied to expel the contents thereof under pressure to form the stream.  Weight means moving from an upper elevation to a lower elevation provides the said force,  The pressure source also includes means to release, in discrete quantums of mass, the weight means for downward movement, in the preferred embodiments, without substantial impediment other than the pressurizing means.  This provides sufficient force to supply a stream at a usefully high pressure, for example one which can drive a turbine wheel or a linear actuator at a useful velocity.  In a preferred form, the weight means is a buoyant body, and the pressure source includes lift means to float the buoyant body to the upper elevation, and then to permit it to descend to the lower elevation. Systems which can utilized this power source include rotary shaft drives such as turbines, linear shaft drives (linear actuators), and rotary devices driven by linear drives through unidirectional transmission elements (one-way clutches).  The systems may also include driven elements such as electrical generators.

Abstract: Abstract of the Disclosure A burner, particularly a ceramic burner for the combustion chamber of large blast stoves has intercommunicating chambers for the combustion media air and gas at the mouth end of the burner.  One chamber is located concentrically within the other and a mixer body is located at or adjacent the centre of the burner mouth.  The plate-shaped mixer body contains an annular ring of orifices disposed in the direction of flow downstream of a point in the burner where the combustion media are at least partly brought together and preliminarily mixed.  The mixer body occupies 0.25 to 0.4 times the cross section of the central burner channel, and the total cross section of flow through the orifices in the mixer body is 0.1 to 0.3 times the cross section occupied by the mixer body.  The orifices in the mixer body are disposed on a circle and their longitudinal axes diverge in the direction of flow, and diverge from the axis of the burner plate.  Such a construction and disposition of the mixer body results in the development downstream of the body of a zone of uniform velocity of flow in which the directions of flow fluctuate considerably so that an intimate commixture of air and gas is achieved together with stable combustion and the build-up of undesirable pulsations is minimized or avoided.

Abstract: ABSTRACT Metallurgical treatment using a glow discharge in which a glow discharge is formed in a treatment vessel. The operating current of the glow discharge is interrupted briefly in the event of electric arc formation so to extinguish the arc.  A control signal is produced to cut-off completely the operating current of the glow discharge in the event of a short circuit occurring. The control signal is produced by comparing the operating current with a current threshold value and the operating voltage with a voltage threshold value.    In one embodiment the control signal is produced when the operating current is greater than the threshold current and the operating voltage has not exceeded the threshold voltage for a period longer than the period required to detect and extinguish and electric arc.        In another embodiment, the control signal is produced when the operating current is greater than the threshold current and the operating voltage is less than the electric arc voltage.

Abstract: ABSTRACT        In a magnetic recording device skew between data tracks, recorded on a length of magnetic media, and a magnetic transducer is corrected dynamically by a close loop con-trolled servo system.  When the magnetic transducer is not in transducing relationship with the magnetic media, an offset number is placed into a stop/lock counting means.   The stop/lock counting means is one of the elements which is positioned in the close loop of the servo system.  The stop/ lock counting means outputs a series of pulses as the offset number is decremented.  The pulses are converted to analog voltages which, in turn, energize a motor which rotates a take-up spool (capstan) on which the media is wound passing said magnetic transducer.  Due to the translation of said media, whenever the count in the stop/lock counting means is zero, the magnetic transducer is positioned in registry with the selected data track on the magnetic media.

Abstract: ABSTRACT OF THE DISCLOSURE              The output signal of an l-f (low-frequency) power amplifier is supplied to an electroacoustic transducer, through an inductive element for preventing parasitic oscillation, to cause the inductive element to generate a magnetic flux whose density depends on the output current signal of the power amplifier while a current according to the magnitude of the output voltage signal of the power amplifier is supplied to the current input terminals of a Hall-effect element disposed in the magnetic field induced by the inductive element, so that a dc voltage according to the output power of the l-f power amplifier is taken out of the output terminals of the Hall-effect element.  When the voltage exceeds a predetermined level for a time determined by a circuit having a time constant in accordance with the time constant of temperature rise in the voice coil of the transducer, the l-f signal supplied to the electroacoustic transducer is attenuated by a signal attenuating circuit so that the transducer is prevented from being damaged.
