Abstract: FORCED AIR HEATING UNIT                         Abstract A free-standing unit for heating air in a U-shaped channel surrounding a fire box having a pair of spaced vertical vents for directing the heated forced air to converge in front of the fire box opening to limit air flow towards said openings. Mesh in the vertical vents directs the forced air downward to be combined with the hot forced air from a bottom horizontal vent. A baffle plate depending from the top of the fire-box adjacent the flue port and an opening along the top of the doors ignite the gases adjacent the top and directs some gases back into the fire. By forcing heated air at a low level and drawing cool air from a high level, the air being heated is of a uniform temperature. A hood extending along the top edge of the fire box opening diverts exiting gases back into the fire box. A thermostatical-ly controlled blower creates the forced air and cools the fire box walls.

Abstract: ABSTRACT            A method, including a sequence of process steps, for fabri-cating insulated gate field effect transistors having very short effective channel lengths.  In a first version of the method, the source and drain regions of the device are opened in one process stop and self-alignment of the source and the drain to the gate is achieved in one masking step. The drain region is then masked and the source side of the channel is implanted to adjust the threshold voltage of the high threshold voltage channel region.  In a second version of the method, the source region is opened and self-aligned with the gate prior to the opening of drain region.  Implantation to adjust the threshold voltage of the high threshold voltage channel region takes place before the drain region is opened, and then the drain region is opened and self-aligned with the gate in a further masking step.  In either version, the threshold voltage is adjustable and the channel length is controlled to be a small value.

Abstract: ABSTRACT OF THE DISCLOSURE            Transmitter for an ultrasonic imaging apparatus which includes an array of transducer elements which are apt to be activated by electrical pulses for transmitting ultrasonic pulses in a plurality of directional angles, the pulses provided to the transducer elements having a predetermined position in time with respect to each other in order to define the directional angle of the transmitted ultrasonic waves.  In order to simplify and thereby reduce the cost of the electronic circuits of the transmitter, which in the prior art included expensive arrangements of delay lines, a transmitter is dis-closed which comprises a multiplier forming the product of a pulse and a sequence of pulses the frequency of which is equal to the transmitting frequency.  A first multiplexer is connected to a multiplier input, the multiplexer inputs receiving a number of said pulse sequences each at a given phase angle, said first multiplexer responding to a first control signal in order to supply a first input of the multiplier with a selected one of the pulse sequences having a suitable phase angle.  A second multiplexer is connected to a second input of the multiplier and receives at its inputs a number of pulses having various delays relative to a reference signal and having a duration which overlaps the duration of a number of pulses of said pulse sequence and the intervals between them.  The second multiplexer responds to a second control signal in order to supply a second input of the multiplier with a chosen one of the pulses having a suitable delay relative to the reference signal.  A signal converter is connected to the multiplier output and serves for deriving, a transmitting pulse enveloping a sine wave of the transmitting frequency from the multiplier output signal.

Abstract: A method and apparatus for continuously measuring hydrogen peroxide concentration in a solution such as an eluant in a uranium recovery operation.  The hydrogen peroxide is first decomposed into water and oxygen by contacting it with a catalytic material, e.g. activated carbon.  That portion of the oxygen generated by this decomposition which dissolves, which is directly related to the hydrogen peroxide concentration, is measured with a dissolved oxygen meter which, after calibration, provides a measurement of hydrogen peroxide concentration in the solution.  Structurally, the hydrogen peroxide measuring means is comprised of a housing having an open end adapted to be exposed to the solution to be measured.  A catalytic material is positioned over the open end of the housing and a dissolved oxygen measuring means is positioned within the housing.

Abstract: ABSTRACT OF DISCLOSURE            A quench chamber for a load disconnection switch comprises a synthetic shallow housing defining a narrow quench space for extinguishing electric arcs which develop between a follower knife contact and a stationary spark contact on disconnection of the switch. The follower knife contact is in the form of a blade contact and is arranged for pivotal movement within the quench space.            The shallow housing is formed by an essentially rigid carrier frame to which two elastically deformable plates are fastened which define the side walls of the quench space.  The plates are made of a material which gives off a quench gas to promote rapid extinction of the electric arc.  This arrangment not only ensures low manufacturing costs but also enables the quench chamber to effectively quench electric arcs generated over a wide range of operating currents.
