Abstract: An analog watch or clock is provided with an improved dial illiminator in the form of a molded clear plastic dial cap having a tubular section surrounding and extending axially behind the periphery of the dial and an annular rim section projecting inwardly from the tubular section over and in contact with the dial, and a point light source such as a minature incandescent bulb positioned behind the dial in a recess formed in the tubular section of the dial cap. The rim section of the dial cap typically includes a truncated-conical, light-reflecting outer peripheral surface for reflecting light from the tubular section into the rim section and an inner peripheral surface which defines a central aperture through which the shaft supporting the watch or clock hands passes. In operation, the tubular section of the dial cap functions to distribute light around the entire periphery of the dial while the rim section receives the peripheral light and directs it over the dial toward its center for illumination purposes.

Abstract: A clockwork device for driving a hypodermic syringe comprises a device for holding a syringe and automatically injecting predetermined amounts of fluid into a patient at a controlled rate over a period of time. The device comprises a clockwork mechanism, a syringe coupled thereto and an exterior housing containing the various components. The clockwork mechanism is mounted parallel to the overall length of the syringe within the housing to minimize the size of the device. A two-way releasable clutch is utilized to connect the clockwork mechanism to the syringe driving mechanism for ease of retracting or advancing the driving mechanism.
