The intermittently injected air is used to create intermittent airlifts within the tube and cause aerated liquid to be discharged intermittently from an output port of the tube.

Abstract: A double layer sock is formed on a circular knitting machine so that the inner layer and the outer layer are connected by knit stitches adjacent the toe portion and the inner and outer layer wales adjacent such connection are aligned. A section of knit courses is formed beyond the connected toe portion of both the inner and outer layer as an inner guide segment, an inner clip, an outer guide segment, and an outer clip, with each guide segment formed at a lower stitch density than either the toe portion or the clip that border the guide segment.

Abstract: X- or .gamma.-radiation is utilized during non-destructive examination of a sample, to detect hidden flaws in a test sample by generating a number referred to as a single figure-of-merit. The figure-of-merit is obtained by comparing the set of responses obtained from radiation emanating from a standard sample with a set of responses obtained from radiation emanating from a test sample. The resulting figure-of-merit is then compared with a reference value as an indicator of the presence of a flaw.

Abstract: A portable mosquito net apparatus is formed of a frame, adapted to be sandwiched between a bed mattress and a mattress support surface, typically a mattress spring, and is held in place by the weight of the mattress. The frame mounts a mosquito net support to which a mosquito net is attached in a position over the mattress. The mosquito net is draped down about the edges of the mattress to form an enclosed space. The frame, mosquito net support, and mosquito net can be easily disassembled for storage or transport in a small luggage bag.

Abstract: An electric drinking cup for use while driving a vehicle comprised of a plastic inner liner, a metal outer shell, and an insulation-filled space therebetween. A heating element is associated with the bottom portion of the inner liner, and is electrically connected to a vehicle's electrical system. The plastic inner liner curves around the upper edge of the outer metal shell providing a cup lip, which does not get hot when containing a hot liquid. The plastic inner liner and heating element further provide a diffuse heat that heats liquid, such as coffee or hot chocolate, slowly to the desired temperature such that, when heated, the liquid does not become burned and distasteful. The outer metal shell provides durability.

Abstract: A cup holder for securely holding multiple tapered cups within, and for mounting within an automatic dishwasher. A first plate contains apertures extending therethrough. The apertures are large enough to allow passage of the small bottom ends of tapered cups but small enough to prohibit passage of the relatively larger top ends of the cups. The first plate is supported by legs attached to its underside, such that the bottoms of the cups do not touch the surface upon which the legs rest. The cups are trapped between the first and second plates. The second plate is latched to the first plate by a plurality of extendable arms. Extendable arms are extendable beyond the ends of the cup holder and are mountable upon horizontal members in the upstanding sides of utensil racks provided and used in various styles and makes of automatic dishwashers.

Abstract: A confocal scanning microscope apparatus and method is used to rapidly acquire spectrally resolved images. The confocal scanning microscope apparatus includes optics used to simultaneously acquire at least two points along a scan pattern on a sample plane of a sample, wherein the points include regions of the sample represented by at least two pixels. A detection arm is placed in the path of the light reflected, scattered, or emitted from the sample plane comprising a spectrometer having a slit for receiving such light and a detector array placed behind the spectrometer. The image corresponding to the at least two points is recorded on the first axis of said detector and the spectral resolution thereof is simultaneously recorded on the second axis of said detector. The confocal scanning microscope apparatus and method offers significant improvements to the current techniques for genetic sequencing, as well as significant improvements to traditional confocal scanning microscope applications.

Abstract: A computer implemented method for verifying that a circuit or other system satisfies its specifications, is based on creating a first Boolean formula G representative of the system and its specification and through a series of steps creating a second formula G' having a known logical relationship to G and using the second formula G' to determine whether the system satisfies its specification.

Abstract: A device and method permits detecting, measuring, and recording the intensity of radiation corresponding to a green plant's photoactive spectrum striking a selected site, and utilizing such information alphanumerically and graphically displaying the photoactive radiation exposure in sols incident at the site during a particular portion of a day, an entire day, a week, or an month. The photoactive radiation information provided by the invention device allows gardeners, farmers, researchers and others to match the types of trees, shrubs, crops or other plants that would grow best under the radiation conditions usually incident at the site over a desired, extended time period.

Abstract: A fluid delivery system transfers fluids from a set of containers each of which holds a different type fluid to a group of apparatus, such as washing machines, each of which requires that certain types of fluid be delivered to the apparatus in a certain sequence. The system operates under program control both with regard to sequence in which particular fluids are drawn from the containers and with regard to the apparatus to which the selected fluids are delivered. Fluid pressure in the fluid lines leading to the apparatus is sensed by pressure sensors located along these fluid lines in a manner enabling the operator of the system to immediately know which of several containers are empty.

Abstract: The turn signal system of the invention utilizes a timing circuit to electrically activate and deactivate the flashing turn signal. The invention system also utilizes a pair (left, right) of auxiliary, spring-loaded, momentary contact, normally open switches arranged such that if the driver actuates the turn signal lever for a turn, even though the lever is in the actuated position for that turn, the turn signal flashing circuit is reactivated by the momentary closing of the auxiliary switch and the cycle is restarted. The system of the invention is also characterized by the timing circuit being dependent for its operation on signals received from the vehicle's speed sensor such that the timing circuit will not operate unless there is a signal from the speed sensor to indicate the vehicle is moving.
