Title: Ballast adaptor for improving operation of fluorescent lamps
Inventor: LAGREE JAMES LEO
IPC: H05B41/16
Filed: 1984-12-18
Granted: 1988-07-28
Abstract: A ballast adaptor circuit which makes it possible to use a known rapid start ballast, designed for operating two T12 (38 mm diameter) fluorescent lamps, for operation of two T8 (26 mm diameter) fluorescent lamps (14, 15) by means of a simple modification that does not require cutting wires or extensive rewiring of the ballast device. The adaptor circuit comprises an auxiliary circuit including a tuned series-parallel LC network (21, 24) connected in parallel with either one or both of the lamps. The LC network is tuned to supply an odd harmonic current to the lamps (14, 15), preferably the seventh harmonic. Improved starting is achieved by adding a series RC circuit (27, 28) and a SIDAC trigger device (29) to the network to produce voltage pulses at the peaks of the AC supply voltage.

Granted: 1992-07-02
Abstract: @ A laser having a stabilized external passive cavity is disclosed, with stabilization being effected by modulation of an external mirror positioned along the laser axis. The laser system includes first, second and third spaced mirrors with the second mirror being an output coupler positioned between the first and third mirrors so that an active cavity is defined between the first and second mirrors and a passive cavity is defined between the second and third mirrors. The active cavity feeds, or pumps, the passive cavity which is stabilized by modulation of the third mirror by movement along the laser axis by linear oscillation to Doppler shift the reflected waves within the passive cavity and thereby produce frequencies that do not interfere with the stable modes of the active cavity. By stabilization of the passive cavity, advantages of an intercavity laser device can be realized without incurring the practical disadvantages of such devices, and results in a laser device that is particularly well suited for particle size measurement.

Title: Microocomputer data processing systems permitting bus control by peripheral processing devices
Inventor: DEAN MARK EDWARD
IPC: G06F13/28
Filed: 1985-01-11
Granted: 1989-02-02
Abstract: A microcomputer system includes a main processor (1), a memory (3) and a direct memory access controller (DMA;4) effective to control direct data transfer between the memory and input<sub>/</sub>output devices on channels. Bus control for data transfer is switchable between the DMA and processor by a hold request/acknowledge handshaking sequence between the DMA and processor. A control line (27) from the channels is activated by a peripheral processing device on a channel when it wishes to gain control of the busses for data transfer. Logic means co-act with the handshaking sequence to determine which device gains control of the busses. This logic is responsive to the DMA address enable output (AEN), the hold acknowledge output of the main processor (HLDA) and the channel control line output (-MASTER). When all these are deactivated, control passes to the main processor, when AEN and HLDA only are activated, control passes to the DMA controller and, when all three are activated, control passes to the peripheral processing device.

Abstract: Prodn. of low-alcohol wine is effected by (a) sepg. fruit juice into high- and low-sugar fractions, (b) stripping volatile components, e.g. high-boiling esters, from the fruit juice or the high-sugar fraction and adding them to the low-sugar fraction, and (c) fermenting the low-sugar fraction. Pref. step (a) is effected by freezing the juice to form a slush and passing it through an upwardly inclined separator contg. a screw conveyor, which is rotated with intermittent change of direction while maintaining a net forward motion of solids, so that low-sugar solids are withdrawn from the top and high-sugar liq. from the bottom. The vol. ratio of high-sugar fraction to low-sugar fraction is 40:60 to 70:30, esp. 50:50 to 60:40. The high-sugar fraction is distd. in a spinning-cone fractionation column to strip off 1-15 vol.% volatiles. An extract obtd. by extracting the pressed fruit (e.g. grapes) with water or low-sugar fraction may be added to the finished wine.
