Abstract: ABSTRACT OF THE DISCLOSURE         In a cabinet for electrical or electronic equipment, of the type in which the components of the equipment are mounted on vertically disposed printed circuit boards carried by supports movable on slides within a metal casing so that the supports can be easily withdrawn from the casing, the usual rigid drawer forming the support is replaced by a horizontally disposed printed circuit board movable in slides in the casing which also form connectors making electrical connection with conducting tracks on the horizontal printed circuit board.. The horizontal board also carries a set of similar connectors to receive the vertically disposed printed circuit boards.  The connectors are of the type whose contacts can be held open during insertion or extraction of a printed circuit board so that zero force is required for insertion or extraction.

Abstract: METHOD AND APPARATUS FOR IMPROVED IN SITU COMBUSTION OF PYROLYSIS GASES IN A KILN     ABSTRACT           Temperature control is often a problem in direct-fired rotary kilns for the pyrolysis of carbonaceous materials wherein at least part of the thermal energy for pyrolysis is obtained by in situ combustion of the pyrolysis gases.  The present process and apparatus provides a means by which tempera-ture control, and particularly reduction in intensity of the fireball at the burner end of the kiln and/or moving the fireball away from the burner hood.  This is accomplished by (1) controlling the velocity of any burner gases and the velocity of the in situ air (or other oxygen-containing gas) and (2) the distribution of the in situ air at the burner end of the kiln, such that a Craya-Curtet number of at least 0.2, and preferably at least 0.4, is obtained.  In a preferred embodiment, the in situ air is admitted into the burner hood from a plenum chamber disposed circumferentially around at least a portion of the kiln, the air entering the burner hood through the annulus defined between the outer shell of the kiln and the burner hood.

Abstract: ABSTRACT OF THE DISCLOSURE              A system is described for controlling the speed and direction of rotation of first and second spools in a web transport system in which a web is advanced between the spools by first and second drive motors.          The system incorporates a servo control which continuously reacts to variations in the speed of the spools so as to drive the spools at respective speeds whose sum is constant and proportional to a selectable control voltage.  To achieve this result, the first and second spools, driven, respectively by the first and second drive motors, are coupled to means, such as a corresponding pair of servo generators, for generating electrical outputs representa-tive of the direction and speed of rotation of the spools.        A control voltage, proportional to the sum of the desired speeds of the two spools, is continuously and algebraically summed with the outputs of the two servo generators, the summed signal constituting a motor drive signal.  A motor drive control receives the motor drive signal and selectively applies it to the drive motor associated with the spool upon which the web is to be wound.  The pull thus exerted on the web by the actively driven spool rotates the other spool, both spools thereby rotating their corresponding servo generators. The motor drive signal, derived from the control voltage and the outputs of the servo generators, continuously reflects the changing outputs of the servo generators so as to cause the spools to rotate at respective speeds whose sum is constant and proportional to the control voltage.

Abstract: Abstract of the Disclosure Solvents evaporated from ink solutions in the drying sections of a multi-station printing press can be converted into harmless carbon dioxide and water vapor by heating the dryer exhaust for a given time period above a given oxidation temperature.  The amount of energy required to maintain the oxidation temperature is substantially reduced by preheating the solvent laden exhaust through the use of a pebble bed heat generator prior to introduction of same into the oxidation chamber.  If gases containing a sufficient solvent concentration level are preheated above the solvent ignition temperature, the solvent itself will provide heat of combustion sufficient to maintain the oxidation process.  With this degree of preheat, at high solvent concentration levels, not only is no additional fuel required, but excess heat is generated. In order to maintain the system at minimum fuel consumption and eliminate the excess heat generated which is detrimental to operation of the oxidation chamber, a portion of the preheat section is bypassed by a selected amount of the exhaust such that the temperature in the oxidation chamber may be regulated. Alternatively, the solvent concentration level of the exhaust can be lowered by mixing the dryer exhaust with the floor sweep exhaust (of substantially lower solvent concentration) in regulated proportions.  The latter method has the advantage of providing floor sweep capability without increased cost. Further, the use of solvent concentration (LEL) controls in the dryer sections can enhance the accuracy of the concentration control at the oxidation chamber and substantially reduce the size of the chamber by reducing the volume of exhaust to be processed.

Abstract: ABSTRACT OF THE DISCLOSURE           A signal transmitting circuit is disclosed, wherein a sample-hold circuit, a low pass filter and a sampling circuit are connected in series in the signal transmission line. Assuming that a sampling frequency at both the sample-hold circuit and sampling circuit is fc, a cut-off frequency of the low pass filter is preferably selected about the same as the sampling frequency fc.  This causes the compensation of the frequency response in the transmission line, and particularly the circuit is applicable to a CCD (charge-coupled device) image read-out circuit.  The output of the CCD is something like a sampled signal, so that the application of this system to the CCD signal is very normal and useful.

Abstract: ABSTRACT OF THE DISCLOSURE Method and apparatus are disclosed for detecting antibiotic sus-ceptibilities using serial dilution in liquid media.  A plurality of dif-ferent antibiotics are placed in a large number of small wells in a trans-lucent plastic tray, each antibiotic being placed in a column of wells at serially diluted concentrations.  A bacteria culture of known uniform con-centration is then inoculated into each well.  Following a period sufficient to allow growth, a diffuse uniform light is passed through each of the wells and their contents, and the intensity of the light passing through each well is measured to determine turbidity of the bacterial suspension.  A turbidity value for each well is compared with a value corresponding to zero growth, and this information is processed by a computer which calculates which of the antibiotics are effective to inhibit growth of the bacteria, and the minimum concentration of each effective antibiotic necessary to inhibit growth.  This information is displayed and printed out and provides inter-pretive information to determine the choice and dosage of an antibiotic to be administered to the patient.  The computer is programmed to perform var-ious calibration operations and checking routines to confirm that the in-strument is operating properly and that the test is being conducted properly.

Abstract: AN APPARATUS FOR REMOVING NO-BAKE  COATINGS FROM FOUNDRY SAND, AND  CLASSIFYING THE RECLAIMED SAND                  ABSTRACT OF THE DISCLOSURE         An apparatus for reclaiming no-bake foundry sand is provided, in which a fluidized stream of pneumatically conveyed particles of no-bake coated sand grains traveling at velocity sufficient for transport is discharged against a target to fracture the no-bake rigid coatings from the sand grains on impact.  Certain of the fractured coatings are removed and the sand grains along with any remaining fractured coating particles are directed through a passageway having a fluidizing air stream induced therein.  The air stream entrains and carries off the fractured coatings and fine sand grains so that only sand grains of desired particle size pass through the air stream for subsequent reuse.  Advantageously, the velocity of the air stream is controlled by regulating the cross-sectional area of the passageway at the point at which the air stream is induced.
