Abstract: The tool spindle has a drive plate on which a cutter is mounted.  Drive keys on the drive plate engage slots in the cutter so that the cutter rotates with the drive plate. A clamp bar is provided to clamp the cutter against the drive plate.          The cutter is formed with clearances which register with the clamp bar when the cutter is rotated relative to the clamp bar, so that the cutter may be removed from the drive plate.  A new cutter is then reverse rotated into a position in which it may be clamped by the clamp bar.  A spring holds the clamp bar in its clamping position.  The quick change system also includes two or more locking fingers which are activated by centrifugal force to maintain the cutter clamped to the drive plate even in the event of failure of the spring which normally holds the clamp bar in its clamping position.

Abstract: A mechanical drive for a dual action motor that is used with an oscillating spindle sander is disclosed.  The oscillating spindle sander has a worktable for supporting a workpiece.  A spindle extends upwardly through the worktable and has a sanding surface.  An electrical motor is supported by the worktable and includes a shaft for imparting rotational motion to the spindle.    The mechanical drive is contained within a housing that is supported by the motor and is connected to the motor shaft for imparting reciprocal or axial motion in addition to rotary motion to the spindle.  The mechanical drive includes a speed reducer that is coaxial with the motor shaft.  The speed reducer drives a cam follower that engages a cam in the housing for imparting reciprocal motion to the spindle at a rate much less than the rotational speed imparted to the motor shaft by the motor.  The speed reducer includes a cycloidal gear that engages a complementary ring gear provided in the housing.  The mechanical drive for the dual motion motor is disclosed as being particularly useful in connection with oscillating spindle sanders; however, other applications are also contemplated.

Abstract: The present invention is to a method of screening agents for potential therapeutic efficacy. The method comprises exposing a cell strain that is sensitive to known apoptotic agents to said apoptotic agents and to a potential therapeutic agent. The cell strain is then cultured and cells are removed that display diminished adherence. The remaining, adherent, cells are then incubated in the presence of a proteinase to release proteinase sensitive cells. The proteinase sensitive cells are removed to yield proteinase resistant cells and the proteinase sensitive cells are counted. The proteinase resistant cells are then collected and counted. The agent is determined to have potential therapeutic efficacy if the ratio of proteinase sensitive cells to proteinase resistant cells changes relative to a control as a result of the presence of the agent.

Abstract: A low complexity and low cost transmitted reference spread spectrum communications system provides several methods of generating a suitable wideband carrier, a method for combining the wideband carrier with a narrowband modulated wideband carrier, and a number of implementations of a simple, inexpensive receiver for the transmitted reference communications system. The transmitter includes a balanced modulator for modulating a wideband spreading signal with a narrowband message signal to generate a wideband carrier. A signal combiner combines the wideband carrier with a narrowband modulated wideband carrier to generate a transmitted reference spread spectrum signal. The receiver includes a selectable time delay device having a plurality of taps for receiving a detected received signal from the transmitter. A tap selector selects a delayed signal from the selectable time delay device. A mixer combines output signals of the selectable time delay device and the tap selector, and a leaky integrator receives the mixer output signal and controls the tap selector.      The leaky detector generates the narrowband message signal.

Abstract: A computer system for high-performance video and audio manipulations comprising a locked memory cartridge and an audio/video/compact disk (CD) drive controller/coprocessor. The computer system has a central processing unit (CPU) with at least one bus associated therewith, with the bus having at least one bus line. The cartridge comprises a readable memory, a memory control circuit, a lock control circuit, and a connector all in circuit communication with each other. The connector allows the memory, the memory control circuit, and the lock control circuit to be pluggably connected in circuit communication with the CPU. The memory control circuit scrambles some of the bus lines, thereby scrambling the data in the memory on reset, and unscrambles the bus lines responsive to inputs from the lock control circuit. The lock control circuit monitors the bus, waiting for a proper combination of bus values to be asserted onto the bus, at which time the lock control circuit causes the memory control circuit to unscramble the bus lines. The audio/video/CD drive controller/coprocessor comprises a CPU interface, a CPU cache, a memory controller, a memory bus arbitrator, a DRAM refresher, a video controller, a CD drive controller, a digital signal processor (DSP) sound coprocessor, and a "blitter" graphics coprocessor in an integrated package.
