Title: Producing signals responsive to a parameter of successive objects
Inventor: WELBOURN CHRISTOPHER M
IPC: G01N21/47
Filed: 1985-10-04
Granted: 1990-11-27
Abstract: ABSTRACT OF THE DISCLOSURE          In order to colour sort objects such as peas or sweets, they are dropped in succession through two integrating spheres.  In the first sphere, the object absorbs infra-red radiation and the peak reduction in infra-red flux is detected in order to provide a signal responsive to the size of the object.  In the second sphere, the object is illuminated with white light and the peak reduction in flux is detected by at least, three detectors for three colours determined by filters.  To make the illumination more uniform in the sphere, there is a step around the sphere almost half way down, with the light sources equi-spaced around the step.  The size signal is divided into the respective colour signal in a micro-processor to produce a size-corrected colour signal.

Title: Electrical clamp connector
Inventor: SMITH PHILIP L
IPC: H01R4/24
Filed: 1987-03-27
Granted: 1990-11-27
Abstract: ABSTRACT    An electrical clamp connector with first and second half portions connected together and providing at least two mating grooves for electrical conductors to be electrically bridged.          Bridging plates extend transverse to the grooves in one half portion and oppose corresponding bridging plates in the other half portion.  Each bridging plate has first and second sets of piercing teeth to pierce the conductors at the grooves.  The second half portion has substantially greater depth than the first half portion.  Improved high real torque connecting means are provided by a bolt, a threaded upstanding tubular pipe in the second half portion, a first threaded cylindrical passage underlying the tubular pipe, a flat or curved metal plate with a threaded passage and encapsulated in the second half portion substantially above the bottom of the second half portion, and a second cylindrical passage below the metal plate.  The threaded pipe, threaded first cylindrical passage, threaded plate passage, and second cylindrical passage are precisely aligned, and one continuous thread extends through the pipe, first passage and metal plate by means of drilling the passages in one continuous operation and tapping the passages in another continuous operation   The plate lies within a range of distance below the bottom of the electrical bridging members to allow the metal plate to act as the primary load-bearing member, and to provide sufficient compression and displacement of the intervening material to maintain a loaded connection through bare wire cold flow and high temperature cycling.  The bolt terminates within the connector half to avoid conductor and human injury.

Title: Deepwater floating drilling and production facility incorporating flexible production risers
Inventor: HUNTER ANDREW F
IPC: E21B43/01
Filed: 1987-05-21
Granted: 1992-01-21
Abstract: ABSTRACT OF THE DISCLOSURE          A  method  of  using  a  floating  platform  in deep (1000-3000  feet) water as a drilling/workover and production platform.    By  interconnecting  the  subsea wellheads of at least  one template to the platform using flexible production risers  connected through a reverse loop, the platform may be adjusted  on  its  moorings to position the platform directly over  a  second template for subsequent drilling or workover. This  eliminates  the additional expense of separate drilling platforms   and   workboats.    Further,  wells  of  separate templates  can  be  serviced  separately and the entire field production  need  not  be  completely curtailed during such a workover.

Title: Motor rotation servo control apparatus
Inventor: MACHIDA YUKIHIKO
IPC: G05D13/62
Filed: 1987-06-08
Granted: 1991-06-04
Abstract: ABSTRACT OF THE DISCLOSURE    A motor rotation control apparatus employs a comb filter circuit operable to filter out a signal component and its higher harmonics.  An error signal indicative of an error between actual and target conditions of rotation of the motor is applied to the comb filter circuit after its DC component is removed.  The filtered signal and the error signal are added in a circuit which produces a control signal used to control the motor rotation.  In another aspect of the invention, the error signal is divided into a first digital signal having upper bits of data having a predetermined bit number and a second digital signal having the remaining lower bits of data.  The lower bits of data are delayed a predetermined time and added to the error signal to compensate for lower bits of data which may be ignored in a digital-to-analog converter operable, with a limited bit number, to provide a control analog signal used to control the motor rotation.

Granted: 1992-12-01
Abstract: 63-293/UC9.10 CHIMERIC PEPTIDES FOR NEUROPEPTIDE DELIVERY THROUGH THE BLOOD-BRAIN BARRIER            ABSTRACT OF THE INVENTION      Chimeric peptides adapted for delivering neuro-pharmaceutical  agents,  such as  neuropeptides  into the brain  by  receptor-mediated  transcytosis  through  the blood-brain barrier.   The chimeric peptides  include a peptide which by itself is capable of crossing the blood-brain barrier by transcytosis at a relatively high rate. The transportable peptide is conjugated to a hydrophilic neuropeptide which by itself is transportable only at a very low rate into the brain across the blood-brain barrier.  The resulting chimeric peptide is transported into the brain at a much higher rate than the neuro-peptide alone to thereby provide an effective means for introducing  hydrophilic  neuropeptides  into  the  brain through the blood-brain barrier.

Title: Implied principal busy status indicator for covered calls
Inventor: NALBONE ROBERT D
IPC: H04M3/54
Filed: 1987-11-24
Granted: 1992-03-17
Abstract: IMPLIED PRINCIPAL BUSY STATUS  INDICATOR FOR COVERED CALLS            Abstract The subject implied principal busy status indicator provides all covering users with an indication of the busy/idle status of the principal's line on a covered call.  This is accomplished by equipping each covering user's telephone station set with a principal busy status indicator for every line appearance on the covering user's telephone station set.  When a covered call is diverted from a principal's line to the covering user's telephone station set, the line appearance on which the covered call appears is lighted and the principal busy status indicator associated with the covering user's line appearance indicates the busy/idle status of the principal's line.  The business communication system updates the state of the principal busy status indicator so the covering user knows when the called principal's line is idle.
