Abstract: A drop emitting device including a first linear array of columnar arrays of first nozzle pairs and a second linear array of columnar arrays of second nozzle pairs, wherein the first linear array and the second linear array extend along an X-axis, and wherein the second linear array is adjacent the first linear array such that each first nozzle pair has an associated second nozzle pair displaced therefrom along a Y-axis that is orthogonal to the X-axis. The columnar arrays of first nozzle pairs and the columnar arrays of second nozzle pairs extend obliquely to the X-axis.

Abstract: Methods and compositions are provided for efficient expression of genes in unicellular microorganisms, particularly yeast. The systems involve an expression system employing transcriptional initiation regions from glycolytic enzymes, particularly a chimeric expression system, having a first region providing for regulatable or constitutive expression, a second region providing for transcriptional initiation, where regions one and two are not found joined together in functional relationship in nature, and optionally a sequence providing for a secretory leader and processing signal, where the expression cassette will be joined to a gene which may be homologous or heterologous to the host. The expression cassette can be used on an extrachromosomal element or integrated into the host genome, whereby continuous expression can be achieved or inducible expression is obtained, by virtue of the presence or absence of an inducer.

Abstract: A compact industrial animal trap is provided to effectively, continually and rapidly exterminate rodents and other animal pests in a reliable, efficient and safe manner. The animal trap has a disposal chamber and an elongated killing chamber with a kill pad or other killing means. In the preferred form, the disposal and killing chambers are separated by a vertically moveable scraper wall, the opposite ends of the killing chamber have entrance doors, and the killing chamber has a laterally moveable sidewall and floor to push the killed animal from the killing chamber into the disposal chamber.

Abstract: An industrial animal trap is provided to effectively, continually, and rapidly exterminate rodents, pigeons, and other animal pests in an efficient and safe manner. The animal trap has a feeding chamber, a killing chamber, and an optional discharge chamber, which are separated by moveable walls. In the preferred form, the chambers are in horizontal alignment and the animal trap has a horizontally moveable front wall which sequentially pushes the animal from the feeding chamber to the killing and discharge chambers.

Abstract: A rodent killing device is provided with a plurality of units of feeding and killing chambers, with each feeding chamber positioned directly above a killing chamber, so that the floor of the feeding chamber also forms the ceiling of the killing chamber. The feeding chamber attracts a rodent by bait, which then becomes entrapped within the feeding chamber, whence it is transmitted to the killing chamber by sliding the floor of the feeding chamber outwardly. The killing chamber destroys the rodent by a plurality of spikes impaling the rodent, and then the killed rodent is deposited in a container for subsequent removal. The killing of the rodent is done in a separate chamber so that no leftovers from the rodent or any ill smell is allowed to permeate into the feeding chamber, so that subsequent rodents approaching the feeding chamber are not discouraged from entering into the interior.

Abstract: The present invention is to provide an automatic animal-trapping device, more particularly, to provide a kind of animal-trapping device, used for trapping mice and other like wild animals, which may repeat its operating cycle all over again and catch lots of mice in continuity with special functions of its automatic control mechanisms.
