Abstract: A novel computer-controlled video microscopy system, features a rotatable objective lens turret. The lens turret is a rotatable cylindrical drum having an open end and closed end. A plurality of light-transmitting objective lenses are evenly spaced about the side wall of the cylindrical drum. The objective lenses are each directed perpendicularly to the axis of rotation of the cylindrical drum. A computer is used to select a desired objective lens and signal a motor to rotate the cylindrical drum about its axis of rotation, so as to move the selected objective lens into the path of an approaching light beam. When the light beam enters the drum through the objective lens, a prism or mirror inside the cylindrical drum bends the light beam at a right angle and directs it out of the drum through its open end. An image carried by the light beam is then focused onto the imaging plane of a video camera.

Abstract: A removable tie down brace for a vehicle is disclosed. The brace consists of at least one L-shaped member that is disposed transversely across the roof or cab of the vehicle, resting on hard rubber legs or feet. Two sets of apertures extend through both of the planar surfaces described by the “L” perpendicular to one another, thus allowing the user to secure a wide variety of objects of all sizes and shapes. Various utility attachment means are provided to allow the user to position bungee cords, rope, or the like, in various ways.

Abstract: An air conditioning apparatus suitable for use in small boats having enclosed cabins, comprising an insulated compartment; a cooling coil having an inner surface and an outer surface; a small pump for causing a liquid cooling fluid to travel along a defined flow path leading from the insulated compartment, across the inner surface of the cooling coil, and back to the insulated compartment; and a means for causing air to flow across the outer surface of the cooling coil in heat exchange relationship with the cooling fluid. The cooling fluid is cooled by contact with a slowly melting frozen material stored inside the insulated compartment. No on-board vapor compression refrigeration cycle like those used in conventional marine air conditioning systems is used for either chilling the cooling fluid or refreezing the frozen material after it melts. This leads to a significant decrease in power requirements.

Abstract: A dental flossing apparatus, comprising a length of dental floss having two ends and two floss holders. One floss holder is attached to each end of the dental floss. Each floss holder comprises a flat piece of plastic having an edge with a continuous groove therein. The groove allows dental floss to be wrapped around the floss holder. Each floss holder is molded around one end of the dental floss, forming a very secure bond between the floss and the holder.

Abstract: An article of furniture comprising:a) a support frame comprising two hollow vertical supports and a horizontal strut connecting the upper end of the first vertical support to the upper end of the second vertical support;b) a bench comprising a horizontal support member, a plurality of arm rests mounted on said support member, a seat back, and a means for pivotably mounting said seat back to said plurality of arm rests; andc) a means for suspending the bench from the horizontal strut;wherein the interior of the vertical supports is accessible through doors provided in the vertical supports.

Abstract: The invention is directed to a method of killing or inhibiting the growth of the malaria-causing pathogen Plasmodium falciparum by exposing the pathogen to an effective amount of a preparation comprising a compound selected from the group consisting of:a) a compound of formula I: ##STR1## where ##STR2## b) a compound of formula II; ##STR3## where each R' is --H or each R' is --OH; and c) a compound of formula III; ##STR4## where R" is --NH.sub.2, --H, or --SO.sub.3 M, and where M is H, Na, or K.

Abstract: Disclosed is a watt/watthour meter which is capable of automatically correcting incorrect connections between the apparatus and a multiphase AC system. Each power line of the multiphase system is connected to the watt/watthour meter by means of a voltage input line and a current sensing coil. The apparatus is able to determine whether a given voltage input line is connected to the same power line as a given current sensing coil by determining whether the voltage applied to the given voltage input line has the same phase as the current running through the given current sensing coil. If the current and the voltage are the same, this information is stored, and the given voltage input line may be taken as being connected to the same power line as the given current sensing coil.

Abstract: A checkout counter advertising display includes visible information containing for example an advertisement displayed through a transparent or translucent portion of a countertop of the checkout counter. A customer can signal an operator at the checkout counter that he/she wants to buy merchandise advertised in the display. The signalling can be performed orally or visually, or by activating a signalling device on the countertop.
