Title: Improved pulse light system fluorometer
IPC: G01N21/25
Filed: 1987-04-07
Abstract: There is disclosed herein a reference system for a fluoro­
meter designed to detect very low levels of materials tagged 
with fluorophores. There is also disclosed an optical system 
for use in such a system which improves the signal to noise 
ratio. The reference system utilizes pulsed arc light excitation 
which excitation pulses are directed onto a flow cell contain­
ing the fluorescent dye. Fluorescent light emitted from the 
dye is guided to a photomultiplier tube which converts it to 
electrical pulses. A portion of each excitation light pulse is 
guided by a light pipe onto a PIN diode light detector which 
converts these light signals to electrical pulses. A LED refer­
ence light source is pulsed to generate a plurality of reference 
light pulses one of which occurs between each excitation 
pulse. A portion of each of these pulses is guided to each of 
the two light detectors and two more series of electrical 
pulses are generated. A microprocessor then reads the four 
electrical pulses resulting from each pair of light pulses and 
performs a computation on the resulting numbers which indi­
cates the relative concentration of the target concentration 
being assayed. The optical system masks the excitation light 
pulses and the emitted light pulses to minimize the amount of 
scattered excitation light than gets into the emitted light opti­
cal channel and to control the location and size of the image 
projected onto the photomultiplier tube to stabilize its output 
signal. The light pipe and an output lens spatially integrates 
the image of the excitation light mask and focusses this light 
on the PIN diode so that the dancing image of the arc does not 
wander off the face of the PIN diode and destabilize its output 
signal. The action of the flow cell fluid contents spatially in­
tegrates the fluorescent light thereby helping to stabilize the 
output of the photomultiplier tube.

Abstract: An electric motor 1 has a can-like casing 2 and an end 
cap 14 has brush brush gear 20 mounted on a frame 15 prior 
to insertion into the motor 1. The frame 15 holds the brushes 
23 away from the commutator 46 by means of resilient arms 
24 engaging the brush arms 22. As the frame 15 is inserted 
into the motor 1 the arms 24 come against a post 36 which 
bends the arms 24 to disengage them from the brush arms 
22 so that the brushes 23 settle onto the commutators 26. 
The arrangement allows the motor to be fully assembled, 
save for the brush gear, the brush gear being inserted during 
a final assembly stage, and provides an effective way of 
avoiding damage to the brush gear as it is inserted in the 
motor.

Abstract: A method for providing destination and vehicle function 
information to an AGV comprises the steps of providing one 
or more stationary dynamically codeable passage transducers 
(5) at predetermined spaced-apart points along an AGV path 
(220). The AGV path (220) is provided with a separate

AGV (200) response. Additional steps in the method permit 
reprogramming of each transducer (5) by a reader/writer 
(129) on each AGV (200) to provide different instructions to 
a following AGV (200) and also a way of determining priority 
of movement between two converging AGVs (200).

Title: System for internetwork communication between local area networks
IPC: H04L12/46
Filed: 1989-12-20
Abstract: An internetwork communication system provides 
communication from a first local area network to a second, 
ring-type, local area network via a bridge. The bridge 
receives a frame from the first local area network and 
transmits a dummy frame followed by an internetwork transfer 
frame to the second local area network. The internetwork 
transfer frame defines a node of the second local area 
network as a distant apparatus (receiver) and a node of the 
first local area network as a self apparatus (sender). The 
bridge later receives the dummy frame from the second local 
area network, after transmission of the dummy frame around 
the ring, and deletes the dummy frame and the internetwork 
transfer frame received following the dummy frame so that 
the communication in the second local area network does not 
circulate indefinitely around the ring. As an alternative 
to using a dummy frame, the bridge can receive the 
internetwork transfer frame, after circulation around the 
second local area network, and compare the distant apparatus 
of the received internetwork transfer frame with a stored 
distant apparatus address. When the received distant 
apparatus address matches the stored distant apparatus 
address, the bridge deletes the internetwork transfer frame 
from the second local area network.

Filed: 1989-04-28
Abstract: A modular, expandable, low-weight electric motor (10) has a cylindrical, non-magnetic casing (12) formed in axially-aligned sections (28, 30, 32). The casing sections (28, 30, 32) are releasably connected to define a unitary structure with a polygonal exterior surface (22) and a circular interior surface (24). Separate U-shaped stator pole assemblies (58, 84, 86) are releasably mounted against the exterior (24) of the casing (12), each casing section carrying the poles (62, 64) associated with a different motor phase. The poles (62, 64) extending through apertures into the interior of the casing (12), and have active pole faces (66, 68) which are curved and substantially flush with the circular interior surface (24) of the casing (12). A modular rotor (16) is mounted in the interior of the casing (12) and carries magnetic elements (114, 116) in axially spaced-apart sets corresponding to each motor phase. The active faces of the magnetic elements are curved and oriented in a cylindrical arrangement. During each rotation of the rotor (16), the pole faces of each motor phase simultaneously and repeatedly register with the associated magnetic element faces forming air gaps (110, 112), and the magnetic elements (114, 116) simultaneously complete local magnetic circuits (118) with each stator pole assembly. The sets of magnetic rotor elements (114, 116) are indexed circumferentially relative to one another such that the motor is self-starting.
