Abstract: Abstract:         The invention is a controlled laser having an optical resonator, a laser gain medium placed inside the optical resonator, the laser gain medium being capable of emitting light and of lasing with the light.  A multiple layer heterostructure is placed inside the optical resonator, and a unit is provided for varying an optical absorption of the multiple layer heterostructure for the light in order to control an optical gain of the optical resonator thereby controlling lasing of the laser gain medium.  Passive mode locking is achieved by the light emitted by the gain medium controlling the optical absorption of the multiple layer heterostructure.  Active mode locking and modulation are achieved by controlling the optical absorption of the multiple layer heterostructure by applying an electric field to the multiple layer heterostructure.  Control of laser gain by an external light source is achieved by controlling the optical absorption of the multiple layer heterostructure by illuminating it with light from the external light source.  An embodiment of the multiple layer heterostructure fabricated as a GaAs-AlGaAs multiple quantum well with a Type I superlattice band structure is a passive mode locker for a semiconductor diode laser.

Abstract: Abstract:         A workpiece charging unit for a walking beam furnace comprises an entry table and a charging conveyor positioned exteriorly and interiorly of the entry end opening of the furnace.  The charging conveyor can undergo a movement in a generally rectangular path for receipt of a workpiece from the entry table and for subsequent transfer of the workups onto the fixed beams or rails within the heating chamber, where it can be picked up by the walking beam conveyor unit for passage through the heating chamber.  The charging conveyor includes charging beams, a plurality of support posts for the support of the charging beams and a frame structure coupled with horizontal and vertical drive mechanisms.  The arrangement requires the sliding door at the entry end of the furnace to be open for less time than in prior arrangements, and hence has the advantage of reducing loss of furnace heat.

Abstract: ABSTRACT            The present invention is directed to a class of basic monocarboxyamide derivatives of actagardine. Actagardine (INN) is an antibiotic substance produced by actinoplanes strains such as Actinoplanes Sp. ATCC 31048 and Actinoplanes Sp. ATCC 31049 which are described in US patent 4,022,884. Actagardine shows antimicrobial in vitro and in vivo activity against gram-positive organisms. Its complete chemical structure is not yet known but there is only information on its chemical functions and main fragments. In particular, it has been found that actagardine has two carboxylic functions and a primary amino function and can therefore be represented as follows:       The compounds of the invention are monoamide derivatives at one of the carboxy functions of actagardine. More particularly, they are basic monoamide derivatives of actagardine which may be schematically represented by the following formula I:                           Formula I     The compounds of the invention possess improved antimicrobial activity in particular against gram positive bacteria.

Abstract: AGC VOLTAGE GENERATOR WITH AUTOMATIC        RATE SWITCHING Abstract of the Disclosure An AGC voltage generating circuit for an AM radio comprises a product detector adapted to receive an IF signal modulated by an AF signal and synchronously detect the AF signal, a low pass filter adapted to derive from the product detector a filtered voltage indicating the average IF signal strength, and a reference voltage generating circuit ratiometrically related to the low pass filter through a common DC power supply and effective to generate high, medium and low reference voltages ratiometrically related to each other with the high and low reference voltages defining a voltage window about the medium reference voltage. Comparator apparatus is effective to compare the filtered voltage from the low pass filter with the high, medium and low reference voltages from the reference voltage generating circuit.  Current source apparatus is reponsive to the comparator apparatus to control the voltage on a capacitor to maintain the filtered voltage equal to the medium reference voltage. The current source apparatus is further responsive to the comparator apparatus to increase the rate of voltage change across the capacitor when the filtered voltage is outside the voltage window compared to the rate when the filtered voltage is within the voltage window.  The AGC voltage is derived from the voltage on the capacitor.

Abstract: ABSTRACT OF THE DISCLOSURE           A gas,  ionizable to produce a plasma,  is introduced into a region defined within an ion source.  An anode is disposed near one end of that region, and a cathode is located near the other.   A potential is impressed between the anode and the cathode to produce electrons which flow generally in a direction from the cathode toward the anode and bombard the gas to create a plasma.  A magnetic field is established within the region in a manner such that the field strength decreases in the direction from the anode to the cathode.  The direction of the field is generally between the anode and the cathode. The electrons are produced independently of any ion bombardment of the cathode, the magnet is located outside the region on the other side of the anode and the gas is introduced uniformly across the region.
