The windmill assembly is a low drag, streamlined body of revolution that captures the kinetic energy content of the accelerated laminar air surrounding the body. The assembly includes a power-generating, wind-driven turbine that is compact, lightweight and capable of producing a substantially greater output than a conventional windmill with a comparable size rotor. The turbine includes a protruding aerodynamic nose and outer cowling that provide a streamlined, wind-collecting inlet section that constricts the incoming air stream and increases its velocity through the turbine blades. The turbine further includes an exit section designed to exhaust the air stream with a minimum of turbulence. One or more generators are coupled to a turbine wheel, and are electrically switched on and off to maximize the energy capture over the full range of ambient winds. The wind turbine assembly may be configured around a blimp-type body having counter-rotating turbine assemblies.

The invention relates to the field of cytogenetics and the application of genetic diagnostic techniques in pathology and hematology. Specifically, the invention relates to nucleic acid probes that can be used in hybridization techniques for the detection of chromosomal aberrations and other gene rearrangements such as immunoglobulin and T-cell receptor gene rearrangements. The probes provided by the invention are a distinct and balanced set of probes of comparable size, each preferably being from 1 to 100 kb, or smaller, and flanking a potential breakpoint in a chromosome.

The invention provides compositions and methods for making and using sterically enhanced antagonist aptamer conjugates that include a nucleic acid sequence having a specific affinity for a target molecule and a soluble, high molecular weight steric group that augments or facilitates the inhibition of binding to, or interaction with, the target molecule binding partner by the target molecule when bound to the aptamer conjugate. The present invention also provides methods and formulations for ocular delivery of a biologically active molecule by attaching a charged moiety to the biologically active molecule and delivering the biologically active molecule by iontophoresis. Iontophoresis of a biologically active molecule that is conjugated to a high molecular weight neutral moiety, in enhanced by substituting the high molecular weight neutral moiety with a charged molecule of comparable size.

A glove apparatus having a front shell for fielding a ball and a back shell joined to the front shell. The front and back shells cooperate to define a finger region, a heel region, and a thumb region. The ball glove provides more comfort and control than previous gloves. The ball glove may also be lighter weight than conventional gloves of comparable size. A traction panel may be formed in the back shell adjacent an index finger hole.

A tie down anchor that is particularly useful when tying down objects to the ground and may take the place of ordinary tent stakes due to the tie down anchor's superior holding ability when compared to traditional tent stakes. The tie down anchor has a guide having an angled hole. A main stake extends downwardly from the guide and the main stake includes an aperture. A locking spike is adapted for being received in the angled hole. The aperture in the main stake is positioned to receive the locking stake when the locking stake passes through the angled hole. The stake of this invention is small, light, and of a comparable size to traditional tent stakes.

An identification element has a transponder with a data-emitting transmission unit and with a data-receiving reception unit in order to communicate with a device for registering and / or controlling access authorization to spaces or objects. In addition, a control circuit is provided for the transmission unit and reception unit. The transponder is an optical transponder (1.1), the transmission unit of which is a light-emitting transmission unit (1.3) and the reception unit of which is a light-receiving reception unit (1.4). The optical transponder and an autonomous power supply are integrated into the identification element. The identification element is in the shape of a name plate or of an identification element of comparable size which is assigned to an object or body or is to be supported thereon. By virtue of the fact that the transmission unit (1.3) of the optical transponder (1.1) is operated by the control circuit (2.5) in such a way that it transmits optical pulses of less than or equal to 100 nanoseconds repeatedly per second and that the identification element is batteryless, a very small optical transponder is provided which requires little energy and no batteries.

Packaging apparatus and method for inserting food articles into a bag of comparable size. The apparatus has a conveyor that orients the product along a longitudinal axis and delivers the food article to a tray disposed below the conveyor so the product drops from the conveyor and onto the tray. The tray and conveyor move at speeds selected so the product maintains its longitudinal orientation as it drops from the conveyor into the product tray. A bag scoop holds the bag mouth open while the tray carrying the product advances into the bag. A product stripper moves into a position behind the bagged product after passage of the tray so that when the tray returns to its start position, the stripper butts against the end of the product and holds the product while the tray slides out of the bag.

The present invention is an electronic circuit that significantly enhances timing margin in high-speed, digital memory modules. The circuit is implemented is applicable to all switching waveforms on both control and data signal lines that drive the memory bus. Implementation of the present invention also provides a significant reduction in power dissipation compared to memory modules of comparable size and speed utilizing the present art.

An electrical ionizer comprising a fan (5) for producing a laminar flow of air; a positive ion emitter (6b) for ejecting positive ions into the flow of air; a negative ion emitter (6a) for ejecting negative ions into the flow of air; a positive voltage supply (27) to the positive ion emitter; a negative voltage supply (28) to the negative ion emitter; and a microprocessor (30) for controlling the positive and negative voltages to obtain a desired ion balance in the flow of air. The fan (5) is a crossflow fan, resulting in a highly uniform and laminar beam of air along the entire length of the fan, with reduced gaps in the air flow and consistent velocity of air, improving ion balance. The use of a crossflow fan also enables the operating mechanism to be contained within a simple 'teardrop' profile, and for operative parts of the device, for example the motor, the bearings, and electronics such as printed circuit boards to be housed outside the air flow, thereby eliminating a possible source of contamination of the air flow. For a comparable size of ionizer enclosure, approximately twice the mass flow, at higher velocities, can be generated as a similar conventional device using axial fans, and at reduced noise levels.

A power take-off unit for a transaxle is provided with a unique double enveloping worm / worm gear transmission which has a ratio of the number of gear teeth on the worm gear to the number of threads on the worm which is low. The worm / worm gear transmission is more compact than conventional bevel gear systems which have typically been used in power take-off unit applications. The worm and worm gear transmission of the present invention also is quieter in operation and has a higher torque capacity than standard bevel gears of comparable size.
