Abstract: A wave-forming generator for generating surfing waves of the tunnel-wave type on the surface of a body of water. The generator includes a generator hull which is partially submerged in the water, and a means for propelling the hull through the water in a direction of motion. The generator hull has a shaped face which faces generally in the direction of motion. The shaped face has concave curvature in section both parallel and normal to the surface of the water, is inclined with respect to both the surface of the water and the direction of motion, and also has an attitude with respect to said direction.

Abstract: An apparatus for separating out absorbed and entrained moisture from fuel used in a motor vehicle or heating system. A baffle plate exposed to infrared radiation forms the primary functional moisture separating device.

Abstract: A radiant space heating element (12) in the shape substantially of an equilateral triangle for providing uniform distribution of heat by radiation from an interior space (32) that is a passage for an energy source such as hot water, steam, hot stack gases or any other source of infrared energy. The heating element (12) has two radiating surfaces which meet at a vertex (20) so that there is a substantial uniformity of temperature over an area on either side of a line directly under the heating element which is nearly equal to five times the separation of the heater element from the surface. The heating element (12) has insulation (14), a web element (36) that acts both to support the insulation (14) and as a reflector, and a bracket (16).

Abstract: This invention relates to an apparatus for inserting components into workpieces, particularly for insertion of electrical components into printed circuit boards. Multiple component magazines are provided on a shuttle which places the desired component beneath an inserter. The inserter moves through a limited reciprocation to pick up a component from the shuttle, and the shuttle is withdrawn from the path of the inserter. The inserter then moves downward to insert the component. The inserter includes an ejector which maintains contact with the inserted component during withdrawal of the inserter. The ejector includes a shock absorber which gives way if unusual resistance is met during insertion. The shock absorber is spring-biased, and the degree of stiffness of the spring is adjustable.

Abstract: An improvement in specimen kits that reduces significantly the possibility of contamination of the specimen by either user or container; of the patient by the swab used to obtain the specimen; and of a subsequent handler of the container by the specimen. It permits the collected specimen to be transported to the diagnostic processing laboratory in common, widely used medical specimen mailing containers, while permitting the use of swab lengths that are appropriate to the type of specimen desired. The improvement is made possible by a unique double-ended stopper that maintains the specimen container sterile until use, then acts as a cap for engaging the swab shaft for withdrawal while maintaining a tight and sterile shipping container after the specimen is taken and while it is subsequently handled.

Abstract: A pedalling attachment for wheelchairs, to form a composite vehicle therewith, which includes an attachment frame with a pedalling mechanism and novel attachment means thereon. The attachment frame has two slidably and rotatably adjustable frames slidably insertable therein, with attachment means located at the ends thereof which grip appropriate portions of the wheelchair side frames. The attachment means are adjustable with respect to each other, to the attachment frame and to the wheelchair frames, so that a wide variety of sizes, configurations and styles of wheelchairs can be accomodated. The pedalling attachment, when attached to the wheelchair, makes the composite vehicle rigid enough to use safely on streets and highways, and to travel at highway speeds thereon for long distances.

Abstract: A demountable disc cover for spoked wheels and the like. The cover is fabricated of flexible material which fits over a removable hoop held inside of and adjacent to the wheel rim. The cover is fabricatred with a peripheral casing having a stretch cord therein, which performs the function of holding the cover tautly on the hoop over the spoke. A multiplicity of peripheral clips holds the cover in place, each clip fitting snugly over a spoke nipple and having a gripper thereon oriented orthogonal to the spoke, which gripper fits over the edge of the hoop.

Abstract: An improved microprocessor controller program, for soft ice cream manufacturing machines and the like, for maintaining the quality of the frozen product during times of low usage, when such products have a tendency to "age" in both consistency and flavor. The controller keeps track of the quantity of product served during a given base period, and reduces the serving temperature of the product a preselected amount each time a given quantity has not been served therein. The serving temperature is reset to the desired serving temperature whenever said given quantity has been served, thereby avoiding the quality problem which could arise if said given quantity were served at the beginning of one base period but not until the very end of the following base period, thus allowing nearly two base period to elapse without a desired reduction in temperature.

Abstract: An improved photosensitive motion detector which detects abrupt changes within a field of view while ignoring gradual changes in ambient lighting therein. In addition, sensitivity to such changes is maintained without regard to the intensity level of the ambient light, and is not sensitive to the "flickering" of fluorescent lamps. Light from said field of view, which can contain an abrupt discontinuity therein, is focussed upon two substantially identical photocells, each of which is in parallel with one of two substantially identical photoresistors, each of which is closely optically coupled to one of two LEDs connected in parallel but in reverse polarity from a common junction to a common potential.

Abstract: A noiseless rotary detent switch, wherein a ferromagnetic projection passes in close proximity to a magnetic pole, in combination with a first photoelectric detector for detecting the leading and trailing edges of said projection and a second photoelectric detector for detecting the presence or absence of said projection, the magnetic attraction between said projection and said pole providing the noiseless detent action and said first and said second photoelectric detectors providing electric signals for actuating switches in a sequence corresponding to that of the direction of rotation of said rotary switch.

Abstract: The present invention provides a novel holder for knives or other utensils which tilts forward to present the handles to a prospective user, making it easier, safer, and more convenient to withdraw the utensils from their place of storage.

Abstract: This invention consists of a geometrically patterned lens for primary uses in the field of image projection and refraction.

Abstract: A soft ice cream machine which has a controller in contact with a freezing chamber. The controller is provided with temperature information from a temperature sensor, which senses when the temperature of the ice cream is approaching a temperature which could bring about freeze-up and disables the compressor until the mixture warms up a selectable amount. The controller automatically switches the refrigeration compressor and the mixer and auger to a standby condition when the controller senses that the dispensing spigot has not been actuated. The controller further senses when the temperature of the ice cream in the freezing chamber is approaching a temperature which would give an inadequately frozen product unacceptable to consumers.

Abstract: The present invention is a collapsible, highly portable camp stove that is light in weight, can be used on fairly uneven surfaces, is strong and stable, can be put together and taken apart easily, has little bulk, and is easy to pack and carry.The stove consists of several simply-shaped frame members that are assembled around one or more standard burner units. The members are either flat or have simple shapes that have little bulk and, when assembled, provide a rigid, strong and stable structure with easily operated heating units. When disassembled, the parts can be wrapped in a pouch of flexible material and folded into a flat, relatively flexible configuration.

Abstract: The present invention is a foldable demountable digging tool that is reasonable in cost, simple and rugged in construction, small in size and light in weight, and safe and easy to carry and use. These features are obtained by pivotally attaching a holding member to one end of a digging member, permitting the holding member to be folded into the concave side of the digging member, with the handle end of the holding member slightly overlapping the pointed end of the digging member. The folding action permits the tool to be reduced in length to approximately one-half of its opened length.
