Title: Bushing for locking an inner race of a bearing on a shaft
Inventor: LORIMER DALE
IPC: F16C35/063
Filed: 1993-01-19
Abstract: ABSTRACT OF THE DISCLOSURE A bushing for locking an inner race of a bearing on a shaft.  The bushing includes an inner sleeve having a first end,  a second end,  an interior surface,  and an exterior surface.  The inner sleeve is split longitudinally between the first end and the second end.  The exterior surface is tapered from the first end to the second end.   An outer sleeve is provided having a first end, a second end, an interior surface and an exterior surface.  The interior surface is tapered from the first end to the second end.  The first end of the outer sleeve telescopically receives the second end of the inner sleeve.  As the first end of the outer sleeve is slid toward the first end of the inner sleeve the tapered interior surface of the outer sleeve compresses the longitudinal split in the inner sleeve thereby bringing the interior surface of the inner sleeve into engagement with the shaft.

Title: Reciprocating action miller
Inventor: EDDY WILLIAM A
IPC: B02C13/286
Filed: 1991-08-30
Abstract: A self-contained reciprocating action miller (10) having a grinding rotor (46) mill housed within a mill housing (15) and rotating about a grinding rotor axis (72). A refuse material hopper (12) mounted above the mill housing (15) has a convex floor (70) with an opening (19) therein to expose the grinding rotor (46).  Reciprocating feed apparatus (14) mounted within the refuse hopper (12) reciprocates two parallel, spaced-apart vertical push walls (42, 44) along an axis parallel to the grinding rotor axis (72) to feed the material into the grinding rotor (46) at a steady rate.  Control projections (60) are positioned adjacent the rotor (46) for selectively handling and controlling the flow of different sized materials in the hopper (12) into the grinding rotor (46). Shear plates (86) in the form of segments of a circle are positioned adjacent the rotor (46) for comminuting shreddable or grindable material while guiding non-comminutable materials through the mill (10). A reversible rotor (46), stator (16), and discharge chute (18) allow the comminuted material to be discharged from either side of the mill (10) with no loss of grinding efficiency.

Title: Programmable architecture and methods for motion estimation
Inventor: FANDRIANTO JAN
IPC: H04N19/513
Filed: 1993-03-11
Abstract: PROGRAMMABLE ARCHITECTURE AND METHODS FOR             MOTION ESTIMATION                     Jan Fandrianto Chi Shin Wang Hedley K. J. Rainnie Sehat Sutardja Bryan R. Martin ABSTRACT            A programmable motion estimator includes one dual ported memory for storing an image block, the prediction error, and a temporary block used in interpolation, and a pixel-group random access dual ported memory for storing a  search window.  The two ports of the two memories are selectively applied to an arithmetic logic unit,  or ALU,  through a multiplexer.   One output of the ALU provides an absolute difference, which is furnished to a tree adder.   Another output of the ALU provides an average value or a difference value, as selected, which is routed to the inputs of the image memory and the search memory.   In motion vector searching,  the  ALU  performs  pixel  absolute  difference arithmetic using the pixel groups from the image memory and from the search memory, and determines a sum of absolute differences in the tree adder.  In half pixel interpolation, the ALU performs pixel averaging arithmetic using pixel groups from the search memory, and writes back to the search memory.   In quarter pixel interpolation, the ACU performs pixel averaging arithmetic using pixel groups from the image and search memories, and writes back to the search memory. In some quarter pixel interpolations, temporary interpolated blocks  from the  image memory are used to  interpolated quarter pixel blocks.  These temporary blocks are obtained by pixel averaging in the ALU using pixel groups from the search memory.  In error prediction determination, the ALU performs pixel subtraction using the pixel groups from the image memory and from the search memory, and writes back to the image memory.

Title: Rotary joint assembly
Inventor: BECCIA FERDINANDO
IPC: B21B27/08
Filed: 1992-08-24
Abstract: ABSTRACT:            A rotary joint assembly (as shown in Figure 3) has a casing 70.  Coolant is supplied via inlet nipple 74 to pipe 72 and returns via passage 96 to exit from outlet nipple 80.  Casing 70 secures the rotary joint assembly to a rotary body (not shown) to which coolant is to be supplied.  A bearer 94 is connected to the rotary body by a flange 100.  A stationary water seal 110, for example of nitrile, acts as both the seal and bearing for the rotary joint.  A grease seal 108 isolates the grease of the rotary body from the coolant supply.  A bush 82 is screw-threaded into the casing 70 to carry the water and grease seals 110, 108 respectively.  No rotating seals are employed and the joint assembly can be secured to the rotary body directly.  The rotary joint can provide single or two-way flow. The joint may also be made with the outer casing made in two parts (frontispiece and end piece) and without bush 82.  The casing 70 of the rotary joint assembly may be made of mild steel and the rotor/bearer 94 may be chromium plated stainless steel.

Title: Using portable condensation nuclei counters to track sources of indoor air contaminants
Inventor: FOGARTY RICHARD
IPC: G01N15/06
Filed: 1994-02-01
Abstract: The investigation of indoor air quality (IAQ) complaints is complex since, unlike industrial settings, there is no obvious source of contaminants. In general, though, the sources of contamination fall into one of three categories - particulates, gases/vapours and microbial material. This patent application relates to the investigation of contamination by particulates, and specifically, particulates of less than 1 micron in aerodynamic diameter..            The most popular, current investigative techniques are:   i) to test for carbon dioxide as an estimation of fresh air supply, and ii) static tests for the concentrations of particulates in the air. Once the presence of the dust is verified, attempts are made to identify and eliminate the source.   This new technique uses a different logic. Rather than relying on static tests, this technique uses a detector sensitive to minute quantities of sub-micron particles to track sources of any particulates so that they may be addressed. The detector used is a condensation nuclei counter.            The key points of the technique are:   1 ) it is an active technique, where the source is aggressively tracked, as opposed to passively monitored.   2) it relies on a meter with both a fast response time and a sensitive detector; 3) the evaluation is usually completed within a matter of hours.
