Abstract: A  vacuum  packaging  apparatus  for  packaging  a  product between a plastic film and a backing card comprises a base having  a  stationary  heating  hood.    A  reciprocal  table  is mounted on the base beneath the hood.  Two packaging wells are mounted side by side on the table, each well being dimensioned for holding a backing board on which the product is placed for packaging. The reciprocal table moves laterally on the base so that when one packaging well is in a packaging position under the hood, the other packaging well is not and extends out from beneath  the hood.   A sealing  frame  is mounted on the base beneath the hood for holding a sheet of wrapping material and moves  vertically between  a  raised  position  and  a  lowered position.    In  the  raised  position,  the  sealing  frame  is adjacent the heating hood to heat the sheet.   In the lowered position the sealing frame is adjacent the packaging well which is in packaging position to place the heated sheet over the board.  Vacuum motors are mounted in the base beneath the hood, under the reciprocal table.  When the sealing frame is lowered to place the heated sheet over the board in packaging position, a vacuum is drawn against the backing board to seal the heated sheet over the product onto the backing board.   A method for packaging using the apparatus is also included.

Title: Dc current comparator circuit for generating an adjustable output proportional to an input signal
Inventor: SO EDDY
IPC: G01R19/165
Filed: 1992-02-14
Granted: 1997-03-18
Abstract: A DC current-comparator-based circuit generates an adjustable output proportional to an input signal, i.e. an input voltage or current.  One use of the circuit is in the formation of a DC resistance bridge that can be controlled automatically by a microprocessor.  The ends of a pair of test resistors (the resistances of which are to be compared) are connected to respective ratio windings of the current comparator.  The same potential is applied across these resistors by a master power supply.  A microprocessor is alternately supplied with two voltage signals, a first being proportional to the current in a variable one of the ratio windings of the comparator, and the second being proportional to any inequality between the current in the other ratio winding and the test resistor to which it is connected.  The microprocessor controls a slave power supply that receives both the first signal and a third signal that is indicative of any unbalance in the bridge.  Balance is achieved by adjusting the variable ratio winding.  Another use of the basic circuit is in the formation of an improved digital-to-analog converter, in which case the digital input controls the number of turns on the variable winding and the third signal provides the equivalent analog output.

Abstract: A method is disclosed for protecting a growing crop from pathogens comprising applying to the growing crop and to any pathogen present thereon a compound capable of generating an active oligomer elicitor in the crop or the pathogen. The compound is applied with a penetrating agent which aids in the entry of the compound into the cuticle layer of the growing crop or the pathogen. The elicitor is generated in the crop or the pathogen in an amount effective to elicit production in the crop of an anti-pathogenic agent. When the elicitor is generated in a pathogen present on the harvested crop, the elicitor is generated in sufficient amount to transfer into the crop, which transfer may be aided by the presence of said penetrating agent, in order to produce the desired phytoalexins in the harvested crop. Also disclosed is a composition comprising the above compound and a penetrating agent for the compound as well as a growing crop treated with the above composition.

Title: Amplifying circuit arrangement
Inventor: BRAUN KLAUS
IPC: H04B10/29
Filed: 1992-06-25
Granted: 1998-05-26
Abstract: In an amplifying circuit arrangement, for example, for an optical receiver in which the light-sensitive components have a high-ohmic output, the receiver is matched to a low-noise, low-ohmic amplifier by way of a tuned .lambda./4 circuit having correspondingly selected taps.    The optical receiver offers greater sensitivity in a relatively narrow frequency range.  Moreover, it is frequency selective and eliminates the great expenditures connected with conventional optical receivers.    Broadband amplifying circuit arrangements, particularly, optical receivers (E) for, for example, cable television installations, contain a passive receiver module (PM) for distortion-free conversion of broadband optical analog signals into electrical signals.  The passive receiver module (PM) contains a transmitter (UE) for matching the impedance of a light-sensitive element (PD)  to the input impedance of a broadband amplifier (BK) connected to the output.
