Title: Apparatus for the continuous determination of two physical properties of the constituents of a smokable article
Inventor: FEDERLE HARTMUT
IPC: A24C5/18
Filed: 1988-03-21
Granted: 1993-12-21
Abstract: ABSTRACT OF THE DISCLOSURE            An apparatus for the continuous determination of two physical proper-ties of the constituents of a smokable article from the mechanical properties of a rod of tobacco or filter fibres during the production of said rod employs a format finger for compacting the rod of tobacco or filter fibres to a predetermined diameter; the format finger made from hard metal comprises at a first point, at which the diameter of the rod corresponds substantially to the diameter of the finished rod, at least one opening for subjecting the rod to a gas stream; the one or each opening is connected via a critically traversed nozzle in a supply conduit to a gas source; a measuring-value transducer deter-mines the pressure drop of the gas stream with constant volume occurring at the rod and thus the draw resistance. At a second point of the format finger a transducer of the temperature of the format finger caused by the friction heat at a predetermined conveying speed of the rod is disposed in a blind bore; said temperature represents a measure for the hardness of the smokable article.

Title: Current mode motor control circuit
Inventor: GRITTER DAVID J
IPC: B60L15/02
Filed: 1988-03-29
Granted: 1992-01-14
Abstract: ABSTRACT             A field-oriented controller for a 3 phase induction motor is powered by a dc power source through a static inverter.  Current reference signals are compared with current feedback to produce error signals.  They are amplified by a proportional plus integral amplifier, whose output goes to a threshold comparator having negligible hysteresis.  Flip-flops, through which the threshold comparators' gating signal outputs are fed, are clocked at a fixed frequency to introduce pseudo-randomness into the gating times.  This reduces apparent acoustic noise of the motor.  Asymmetrical anti-overlap delays for the gating signals are made long enough to serve also as the principal means for limiting the maximum frequency of gating.  Locking circuitry overrides the proportional integral error signal in one phase at a time, and holds the inverter's gating in one switching state throughout the approximate middle 60° interval of each phase.  During each such 60° locking interval, the integration capacitor of that phase's proportional plus integral error amplifier is short ciruited to prevent motor current transients at the end of the interval.  The locking circuitry is disabled at very low speeds.

Title: Method for regulating plant growth
Inventor: KINNERSLEY ALAN M
IPC: A01N37/36

Granted: 1993-01-12
Abstract: METHOD FOR REGULATING PLANT GROWTH           ABSTRACT           A process for increasing the rate of plant growth.  Plants are treated with one or more acids, which are condensation products of glycolic and/or L-lactic acid.  These acids also increase the concentration of chlorophyll, increase the rate of new plant formation when plants are propagated by tissue culture, decrease the amount of added nutrients required for plant growth, and protect plants against the toxic effects of salts.  Certain of the acids are useful for increasing the rate of root formation in the plant.

Title: Articles including thermosetting-powder surface-coatings
Inventor: LEACH ROGER J
IPC: B32B17/10
Filed: 1988-07-08
Granted: 1994-10-25
Abstract: Abstract Articles including Thermosetting-Powder Surface-Coatings Manufacture of an article incorporating a thermosetting -powder surface-coating includes bonding a component of the article to the coating by contacting the melted powder with the component before curing takes place, and maintaining it in contact through curing. In a glass architectural panel, an aluminum foil is bonded in this way to a polyester/triglycidyl-isocyanurate powder coating on the silane-primed back of the facing glass; the metal foil is backed by a plastics or rubber open-cell material to enhance resistance of the glass to impact, and also, together with the foil, resistance to thermal shock. The coating includes pigmentation to give the effect of colored glass, or is clear to allow the contact-surface of the metal to show through; and further decorative effect is obtained by pigmentation variation in the coating and/or partial metallization of the glass back-surface. The technique is also applied to bonding fittings to the powder-coated face of a door; of decals of cured powder-coating material to, or within, powder-coatings; of glass over apertures in metal walls; and of glass to glass in building up a laminate.

Abstract: The invention is a process of selectively and quantitatively removing and concentrating at least one selected ion present in low concentration with other ions in higher concentration in a multiple ion solution.   The method comprises bringing a complexing agent for the selected ion(s) into contact with a sufficient determined quantity of said multiple ion solution to remove and concentrate the selected ion(s) from the multiple ion solution; removing the multiple ion solution, from which the complexing agent has been removed, the  selected  ions  from  the  complexing  agent having  the  selected  ion(s) complexed therewith, bringing the complexing agent complexed with selected ion(s) into contact with a determined quantity of receiving liquid to break the  complex  and  remove  the  selected  and  concentrated  ion(s)  from  the complexing agent therein, and determining the concentration of selected ion(s) in said receiving liquid from which the concentration of selected ion(s) in the  multiple  ion  solution  can be  calculated.    The  metal  ions  in  low concentration are often heavy metal ions, such as lead ions, and the process finds particularly advantageous utility in the determination of lead content in ppb in drinking water. The preferred apparatus for carrying out the process is a column packed with silica gel or silica-bonded macrocycle as the complexing agent which is preferably selected from the families consisting of

Title: Internal combustion engine noise reduction plate
Inventor: BALLHEIMER BENNY
IPC: F01M1/06
Filed: 1988-11-08
Granted: 1993-07-13
Abstract: Abstract of the Disclosure Internal Combustion Engine Noise Reduction Plate Rigidifying or structural members are used to increase structural stiffness of cylinder block and consequently have reduced vibrations and noise emitted therefrom.  These devices in the past have reduced serviceability, increased engine component complexity, increased cost and allowed additional interfaces for lubricant to leak therefrom.  The subject structural member or rigidifying member provides a simple, inexpensive, light-weight solution to increasing structural stiffness of cylinder block.  The subject structural member has an uninterrupted flange therearound and a plurality of equally spaced longitudinally positioned openings therethrough.  The flange is secured in frictional contact with the inner mounting surface inside the oil pan.  Thus, the interface for lubrication leakage of past members ha been eliminated.  The openings have reduced the weight of the member and provide an opening through which the crankshaft can swing preventing the need to increase the engine height.  The structural member is free of connection with the main bearing caps which reduces component complexability, cost and simplifies servicaability.

Abstract: ABSTRACT OF THE DISCLOSURE            A fault current limiter in which a resistor is inserted by a running arc.  The arc is allowed to burn in a commutating unit until the current zero-crossing.   Upon the passage through zero the arc is extinguished and the current is commutated to a  shunt resistor.  The commutating unit comprises a gap-formed nozzle, in which the arc is burning. The nozzle is defined by two nozzle halves of a material which gives off gas under the influence of the arc.  Close to the nozzle inlet is a pressure accumulating chamber, in which an overpressure is built up during the arcing time. After  current  zero-crossing,  the hot  arc  residues  are effectively vented by means of the overpressure in the pressure accumulating chamber.  For cooling the gas in the chamber and for guiding the gas flow, the chamber is divided into small sub-volumes defined by metal plates.
