Inventor: FAYERMAN JEFFREY TOBIN
IPC: C12R1/465
Filed: 1989-08-03
Abstract: Novel vectors and methods for a single-­stranded DNA mediated gene transfer system via transformation, fusion or transduction of  Streptomyces , other actinomycetes, and  E. coli  using a variety of vectors. Phasmid shuttle vectors of the invention are particularly useful as single-stranded vectors that appear to bypass one or more host cell restriction systems, and thus increase the efficiency of gene transfer into highly restrictive host cell systems. New and useful vectors are provided that allow for the cloning of genes both for increasing the yields of known antibiotics and also for producing new antibiotics, antibiotic derivatives, or any other useful gene product, including a variety of mammalian protein products.

Abstract: The voltage comparison circuit uses digital gates formed into at least two pairs of flip flops, one digital gate having a volt reference supply to and acting to disconnect a load from a source when the voltage of the source declines below a predetermined threshold. In another aspect the circuit provides further digital gates which operate upon transistors and cycle a load for connection to a source on a duty cycle of 100 to 150 seconds on and off so that the load is provided with an intermitten secondary energy source which provides limited drain on the permanent source, which if it be a battery or a storage battery insures that the battery is not drained on a continuous basis even though the load may so demand. The circuit also monitors the voltage threshold of the primary source so that should it fall below that threshold the load is disconnected.

Abstract: When supplying conditioned air to locations or rooms (1) on a floor or story of a multi-story building, an air conditioning unit (2) will deliver conditioned air to a cavity (3) located beneath a floor surface of the floor or story served by the unit. Box-like supply air terminal devices (10) are placed over openings provided at desired positions in the floor surface. The terminal devices comprise a centrally positioned supply channel (14) and a thermostat controlled valve means for regu­lating the amount of air supplied. Circulated air is introduced into the unit (2) at a level within the occupied zone of the location or room served. The floor connected supply air terminal devices lack separate fans and deliver air at a level which is less than about 1 meter above the level of the floor surface, whereas contaminated air is discharged from the location or room through exhaust air terminal devices located immediately beneath the ceiling of the location served. The supply air terminal devices (10) may be located in the vicinity of work areas, e.g. writing desks present in the loca­tion or room served, and are provided with a space through which cables can be drawn to respective work places.

Abstract: Two tone generators (20, 21) having different tone generation systems, e.g., PCM type and an FM type, are provided. There are tone generation modes designating combination of tone generation in these tone generators and one can be selected from among them. There are, for example, a simple mixing mode, a delay mode in which start of tone generation in one tone generator is delayed from that in the other and a crossfade mode in which a tone signal is generated first in one tone generator and tone generation is switched to the other tone generator and envelope levels of output tone signals of the two tone generators are crossfaded during a switching period. Delay time in the delay mode and switching time in the crossfade mode can be variably controlled in accordance with a key scaling and/or other factors. A tone may be generated at a sampling frequency synchronized with a pitch in one tone generator and at a sampling frequency which is not synchronized with the pitch in the other tone generator. A phase of one cycle may be divided into plural sections and a complex waveform can be generated by converting the phase address signal in accordance with a function peculiar to   each phase section and accessing a waveform memory with the converted address signal.

Abstract: A foreign object detecting method and device are for detecting foreign objects mixed in a liquid filling a transparent container. The foreign object detecting method comprises the first step of keeping for a set period of time the transparent container rotated in a first rotational direction, the second step of rotating the transparent container in a second rotational direction opposite to the first rotational direction; the third step of taking a transmitted light image of the transparent container while the liquid in the transparent container is substantially stopped after a set period of time from the start of the rotation of the transparent container in the second rotational direction; and the fourth step of scanning the taken transmitted light image along the rotational directions to detect the foreign objects in the liquid based on a difference in brightness between at least two points on a scanning line. Thus the foreign objects mixed in the liquid can be detected discriminately from the flaws and smears of the transparent bottle  per se .

Abstract: There are disclosed novel avermectin derivatives wherein the 3˝- or 3′-methoxy group and/or the 4˝- or 4′-hydroxyl group are replaced by hydrogen. The 3˝- or 3′-desmethoxy-avermectins can further be derivatized at the 4˝- or 4′-positions as the amino, semicarbazone or oxime analogs. The 3˝- or 3′-desmethoxy-avermectins are prepared by the reaction of Samarium iodide on the corresponding 4˝- or 4′-oxo-avermectins. The 4˝-or 4′-deoxo-­avermectins are prepared by radical deoxygenation of the corresponding hydroxy-avermectins. Di-de­oxygenated avermectin derivatives are obtained by combination of these two methods or by treating avermectin aglycone or avermectin monosaccharide with a dihydropyran. The new compounds are potent anti-parasitic agents, in particular, the compounds are anthelmintic, insecticidal and acaridical agents.
