Abstract: TITLE;   APPARATUS FOR LOWERING ARTICLES FROM A          BUILDING               ABSTRACT OF THE DISCLOSURE       An apparatus for lowering articles from a building including a tower having a boom extending therefrom.  A transfer carriage is slideably mounted on the boom and has a latching mechanism for engagement with an end plate on the boom.  The carriage also has a mechanism for engaging a cage as the cage is raised by a cable to the carriage and disengaging the cage when the cage reaches the outer end of the boom.  A cable mechanism in cooper-ation with powered drum members lowers and raises the cage while alternately raising and lowering a second cage which is on a boom with a transfer carriage identical to the first mentioned boom and transfer carriage.  The rate of movement of the cable and therefore the rate of travel of the cages is controlled by a hydraulic motor connected to a closed loop conduit, the conduit having an orifice preset to regulate the flow of oil to and from the motor which in turn regulates the speed of the cable drums.

Abstract: ABSTRACT OF THE DISCLOSURE     The power tongs control systems described herein include a hydraulic load transducer in the tongs snub line, the transducer output controlling a shunt valve between the hydraulic lines leading to and from the tongs drive motor.  At a predetermined threshold tongs torque, a switch means is actuated by a Bourbon tube connected to the transducer output.  Actuation of the switch means results in opening of the shunt valve, thereby halting operation of the tongs.  A delay device is provided to maintain the tongs in the disabled configuration for a period of time following initial cut off.  Also disclosed is an adjustable choke valve in series with the shunt valve so that even following the opening of the shunt valve, substantial torque is maintained upon the pipe by the tongs.

Abstract: ABSTRACT           A friction clutch wherein the pressure plate at one side of the clutch disc is axially movably connected with a cover by a set of leaf springs which are disposed at the outer side of the cover, namely at the side which faces the engine of the motor vehicle wherein the clutch is installed.  The cover is driven by the crankshaft of the engine and has raised portions extending toward the engine and being riveted to the respective end portions of the leaf springs.  The other end portions of the leaf springs are riveted to protuberances which are provided on the pressure plate and extend into openings provided therefor in the cover and alternating with the raised portions.  The clutch plate is biased against the adjacent lining of the clutch disc by a diaphragm spring whose radially outermost portion reacts against the cover radially inwardly of the protuberances and which bears against the pressure plate in a region which is located somewhat inwardly of the radially outer-most portion.  The protuberances of the pressure plate need not extend radially outwardly beyond the peripheral surfaces of the linings on the clutch disc.  The leaf springs transmit torque between the cover and the pressure plate and allow the latter to move axially into and from frictional engagement with the adjacent lining. The mounting of such leaf springs at the outer side of the cover contributes to compactness of the friction clutch, as considered in the radial direction of the linings.

Abstract: Abstract of the Disclosure One or more movable storage units each having a reversible motor for driving the units on tracks between stationary storage units to open an aisle between units.          Each unit has leash cord plug holders on its aisle sides.          The movable units have safety sweep bars on one or both sides, safety switches actuated thereby, and a limit switch.  Setting a leash cord plug in its own holder so the leash does not span the aisle that is to be opened provides a move command signal and setting the other leashes so they span the aisles that are too close sets up the control circuitry for causing all units to be driven away from the aisle that is not spanned by a leash.  AND gate circuits must simultaneously have input signals indicative of the limit and sweep switches being true, of the leashes being in spanning condition and true for all aisles that are too close and a command signal resulting from having a leash plug in its own holder before the gates will issue a signal that causes the motors to drive in the proper direction.  Time delay devices are pro-vided for keeping the sweep switches untrue, at least long enough for an obstructing person to get out of a closing aisle before the drive motors are activated again.

Abstract: ABSTRACT OF THE DISCLOSURE      Novel compositions and methods are provided for detecting the presence of a material of interest in a specimen on a solid surface.  A composition useful for detecting the presence of a material of interest in a specimen comprises (1) a detector conjugate comprising a fluorescing moiety bonded to a compound capable of specific binding with the material of interest, or a derivative thereof, and (2) a non-detector conjugate comprising a palomino acid) and a compound having substantial structural and charge similarity to the fluorescing compound and no observable fluorescence, or low level fluorescence of a different wavelength than that of the fluorescing compound, in the region of fluorescence of the fluorescing compound.  In the method of the invention, a specimen, on a solid surface is combined with the detector conjugate and the non-detector conjugate, and the combination is incubated.  Unbound conjugates are removed from the solid surface by washing and then the surface is irradiated with light having a wave length absorbed by the fluorescing compound.  The fluorescent light emitted by the combination is observed and is a function of the amount of the material of interest present in the specimen.

Abstract: ABSTRACT          The application describes digital signal processing of radar video signals to provide an optimum display.  Three interacting components of the system are further described in detail:  a global mean estimating circuit, a statistical analyzer circuit, and a dynamic range compression circuit.          The global mean estimating circuit determines the mean of the amplitude distribution of video signals over a wide section of the display as opposed to a local mean of signals.          A local mean of signals is the mean of the amplitude distribution of video signals occurring in the near vicinity of a point on the display.  The statistical analyzer circuit evaluates the amplitude distribution of video signal samples and controls the gain of the signal path so that the variance of the sampled amplitude distribution follows the variance of a model distribution.  The dynamic range compression circuit functions to compress the range of amplitude distribution in a manner to provide maximum information from the display.

Abstract: ABSTRACT       IMPROVED TAR FRACTION FOR DRIVEWAY SEALERS     USING OXIDIZED COAL TAR DISTILLATE    A driveway sealer less affected by temperature extremes can be made from an oxidized coal tar distilla-tion cut.  The sealer incorporates a middle cut crude distillate which is oxidized to produce a product of desired viscosity.  The sealer incorporating this oxi-dized middle cut is less affected by extremes in weather as compared to regular sealer tar.  It has more con-sistent physical properties.  A significant distinguish-ing characteristic derived from the use of this tar in a driveway sealer is the reduced odor of the resulting sealer.  The oxidation (condensation) step is carried out at elevated temperature by sparging copious quanti-ties of air rapidly into the tar at elevated tempera-tures of the order of about 300°F to 800°F (200°C -430°C).

Abstract: Abstract of the disclosure:     A method is described for the photometric determina-tion of the concentration of a reactant in a reaction in which scattering centers are formed or consumed in the sense of a transition from Rayleigh to Mie scattering by determining the peak rate or reaction (Vmax) and the time from the start of the reaction to the appearance of the peak rate of reaction (tmax).        The concentration is determined as a single value by empirically establishing the functional relationship between concentration, Vmax and tmax using a standard prep-aration, measuring Vmax and tmax on the sample, and deter-mining the concentration of the reactant by means of the relationship between the concentration of the reactant and Vmax and tmax determined on the standard preparation.

The pipe receiving boxes (1) and the lids (2) are made for instance of a low-compressible foam of hydrophobic plastic having a low water permeability, such as a polystyrene foam.  The chambers (6) can receive pipes (7) of varying diameters and are dimension-wise not confined to specific pipe diameters.
