Granted: 1992-03-31
Abstract: TRUCK MOUNTED FERTILIZER APPLICATOR        USING FLUID CONVEYING ABSTRACT OF THE DISCLOSURE A   truck   mounted   particulate   material applicator  which  entrains  metered  amounts  of  the particles  in  a  fluid  for conveying  the  material outwardly along tubes forming boom assemblies.   The metering assembly and the booms are mounted in the mid portion of the truck wheel base for minimizing bouncing, and excess shock loads on the booms during travel,  and also  for providing a centrally located distribution point  for  the metering  assembly.   The present  device  includes  a  unique  manifold  for entraining  particulate  materials  such  as  inorganic fertilizer  or  grains  in  fluid  flow  streams  within tubes in which they form the boom assemblies.   Each tube  carries  the  metered  air  entrained  material  a different distance from the center to cover a wide path.  Separate tubes are directed toward the rear of the truck to spread the material in the path of the truck.

Title: Laying of elongate telecommunications transmission members onto support members
Inventor: AKRE COLLIN A
IPC: G02B6/10

Granted: 1990-12-04
Abstract: LAYING OF ELONGATE TELECOMMUNICATIONS TRANSMISSION            MEMBERS ONTO SUPPORT MEMBERS                  Abstract of the Disclosure Laying a transmission member into a groove extend-ing along a support while passing around the support for more than one revolution in one direction and then in the other. The transmission member is fed from a fixed storage position, through a positioning device and to a laying device while being spaced radially from a passline for the support.  A shielding tube is provided around the passline downstream from the positioning device whereby the support moves through the tube on its way to the laying head whereas the transmission member twists around the tube as it is being fed, thereby holding it separated from the support before reaching the laying head.  Preferably, an alignment device upstream from the laying head aligns the transmission member axially with a guide passage in the laying head.  This latter arrangement is particularly useful when the transmission member is a tube containing optical fibers.

Title: Two wing non-intermeshing rotors for increased performance for usein internal batch mixing machines
Inventor: NORTEY NARKU O
IPC: B29C48/395
Filed: 1987-10-13
Granted: 1991-07-23
Abstract: ABSTRACT OF THE DISCLOSURE             Non-intermeshing two-wing rotors for use in high intensity mixing machines of the batch type provide new sequences and new characteristics of dynamic interactions for achieving advantageously increased mixing effectiveness, improved performance and productivity for such machines.  These new rotors are adapted for driving at unequal speed (unsynchronized rotation) or at equal speed (synchronized rotation), and thus they are adapted for retrofitting into existing mixing machines.  The optimum results are achieved by turning the two rotors at synchronous speed with a phase angle relationship of about 180° between rotors as shown by various well-known performance criteria.  These criteria are plotted, and rating results are tabulated as compared with 0°, 90° and 135° phase angle relationships.  By virtue of driving the rotors at synchronous speed with the phase angle relationship of about 180°, a powerful squeeze-flow mixing action and advantageous pull-down effect on the materials being mixed is produced twice during each cycle of rotation. the mixing chamber of the machine can be loaded with materials to be mixed at a higher "fill factor" than conventionally used.  The ability to use a higher fill factor plus the marked decrease in rejected or unsatisfactory mixed batches achieves a significant increase in productivity with a given size of mixing chamber as compared with prior two-wing rotors.

Abstract: Antibody coated gold sol particles and antibody coated solid phase particles dispersed in an aqueous system react immunologically as a function of the presence of an analyte in a sample to be analyzed to product a collectible, solid phase, gold-containing composite. The composite is collected on a filter or at the bottom of a test tube by centrifugation or gravitation and the analyte inthe sample is determined or detected by direct visual examination of the collected solid phase composite which has a pink or red or purplish coloration as a resultof the gold contained thereby. The materials required for conducting the assay comprise coated gold particles, coated solid phase particles and a collector element such as a filter. The collected, solid phase, metal-containing composite, which may be directly visually examined to determine or detect the gold therein and thus the analyte in the sample, is stable and remains available for confirmation of test results at a later time.

Abstract: Abstract of the Invention An electroluminescent (EL) lamp element and a process for making same.  The EL lamp element has a monolayer of phosphor particles deposited in a resin binder material.  The sizes of the particles are controllably pre-selected to lie within a selected range thereof.  The thickness of the resin binder layer is about one-half that of the average particle size so that the tendency of the resin to migrate through the particles and to cover the surfaces of the particles is prevented.  A second resin binder layer is then deposited over the exposed surfaces of phosphor particles to form a relatively thin monolayer of particles uniformly distributed in the resin binder layers.  If desired, the particles can be coated with a colloidal silica material to prevent any agglomeration thereof when depositing them in the resin binder layer.

Abstract: ABSTRACT OF THE DISCLOSURE      A three-stage non-blocking switching array having twice the number of inputs and outputs for its sub-arrays of its input and output stages as the number of lines to be switched, and having one more sub-array in its intermediate stage than the minimum required to form a non-blocking switching array.  The additional or redundant inputs and outputs are connected with the  non-redundant inputs and outputs such that the redundant inputs are each individually connected with a non-redundant input of a respective other sub-array of the same respective stage.  This construction maintains the non-blocking characteristic of the switching array even if one of the sub-arrays fails since, in such use, redundant substitute paths are available.

Title: Lock mechanism

IPC: E05B63/12
Filed: 1989-01-31
Granted: 1993-05-18
Abstract: ABSTRACT          "LOCK MECHANISM"       A lock bolt mechanism includes a housing on which a lock bolt  is  mounted  for  movement  between  locked  and  unlocked terminal positions.  An inside actuator is rotatably mounted on the housing and a first drive connection links the inside actuator to the lock bolt whereby the lock bolt is caused to move  in  response  to  rotation  of  the  inside  actuator.   An outside actuator is linked to the lock bolt through a second drive connection and is rotatable in order  to move  the lock bolt.  A gear train forms part of the second drive connection and that gear train includes at least one partial gear wheel having a segment thereof with no gear teeth.  A second gear wheel  in the  train  is  adapted  to  engage with  the  partial gear.   Rotation of  the  outside  actuator  causes the partial gear to engage the second gear and thereby cause the second drive connection to operate the lock bolt.  However, when the inside actuator is rotated the second gear wheel is free to rotate out of engagement with the partial gear.  The outside actuator  is  preferably  rotated  through  360°  in  moving  the lock  bolt  between  locked  and unlocked positions.   A  slide plate may be used to bias  the mechanism into  the  terminal positions.
