摘要： A mold for casting contact lenses from an unpolymerized resin such as silicone gum wherein the resin is polymerized by high energy radiation such as an electron beam. One side of the mold is a cap capable of transmitting radiation, which is positioned by a mandrel while the resin is being cast. The mandrel is removed while radiation is applied. Silicone contact lenses cured have substantially greater flexibility at the periphery than at the center may be produced by decreasing the amount of radiation applied to the periphery of the lens.

摘要： There is disclosed an electrocardiographic review system for displaying ECG data for each of eight patients. Whenever the data for a new patient is to be observed, two trend plots are first displayed on the screen. One of these represents the number of heartbeats per minute and the other represents the number of ectopic beats per minute, the time axis being divided into approximately 240 discrete 1-minute intervals so that the trend date for a 4-hour monitoring period can be displayed. The reviewing physician can move a cursor across the screen to a point of particular interest, for example, to a point along the time axis corresponding to a 1-minute interval during which many ectopic beats were detected. Following this, when a display key in the system is operated, a 4-second stationary display of the first ECG waveform of interest which occurred during that 1minute interval is formed. Thereafter, each operation of the display key controls the display of another 4-second ECG waveform. In this manner, the reviewing physician can determine those intervals during monitoring which are of particular interest, and can then immediately control the display of the successive 4-second ECG waveforms on the screen. The same screen is thus used to display both compressed-time trend data, and expanded-time ECG waveforms.

摘要： A liquid leak stop for an implantable heart pacer. There is disclosed an implantable heart pacer for providing stimulation to the heart of a patient. The pacer includes a heartbeat detector, a pulse generator, batteries for powering or energizing the electronics, and electrodes or terminals for connection to the heart. Human body fluids tend to leak into the electrode throat or connector receptacle of the implantable pacer. This leakage can cause pacer malfunction. There are disclosed means for halting this leakage along conductors connecting the pacerexternal electrodes and the pacer-internal electronics.

摘要： Improving the light-transmitting efficiency of a clad lightconducting fiber by minimizing core-cladding interfacial defects. Elongated open channels extending longitudinally of the fiber are formed within the cladding to cushion the expansion of gases existing and/or created along the fiber core-cladding interface during fabrication of the fiber.

摘要： Manufacturing semifinished and certain finished opthalmic lenses without surface grinding and polishing operation. A flat preform comprised of a thickness of a desired lens glass, e.g. ophthalmic crown, and a lesser thickness of a chemically soluble protective glass fused to at least one side of the lens glass with a smooth, blemish-free interface is produced and thence cut and pressed or slumped to the meniscus shape desired of the ophthalmic lens. The lens is completed by removing the protective glass with a suitable solvent to expose the underlying smooth, blemish free surface(s) of the lens glass for ophthalmic use without further working.

摘要： A simulator having a resilient spherical section which flexes in a consistent manner when subjected to a fluid pulse mounted by frictional engagement with a tapered base inserted into the end of a body opposite the spherical surface without causing distortion or stresses within the body producing inconsistent flexing of the spherical section. A plurality of such devices may be mounted on a convenient holder for individual presentation to the fluid pulse of an instrument, such as a tonometer, to simulate specific interocular pressures for verification.

摘要： A quick discharge circuit for a pacer''s nuclear power supply. A pacer capable of implantation within the body of a patient and capable of being powered by at least one nuclear battery is disclosed. Voltage from a single nuclear battery is increased by a factor of about 25 to 30 in order to provide a voltage level adequate to power pacer circuitry. A restartable DC-DC converter is used for this purpose. But if the converter malfunctions the load voltage must be reduced below a certain level for the converter to be automatically restarted. The present invention relates to means for reducing the time from converter malfunction to resumption of converter operation in order to reduce the corresponding inoperative pacer time period.

摘要： A novel glass exhibits fluorescence from trivalent neodymium ions at a wavelength of approximately 1.06 micrometers. The glass consists essentially of about 98 weight percent of a host glass and about 2 weight percent of a compound which contributes trivalent neodymium ions to the glass. The host glass is a fluoroborate and consists essentially of 10 to 60 mol percent of B2O3 and 40 to 90 mol percent of a fluoride glass modifier selected from the group consisting of BaF2, LaF3, AlF3, PbF2, and combinations thereof. The neodymium compound is selected from the group consisting of Nd2O3and NdF3.
