Abstract: An improved evaporator/ice forming assembly for an ice machine is disclosed. The assembly comprises evaporator tubing sections having one or more integrally formed fin elements; evaporator system connectors adapted for connecting the tubing sections together to form a sealed evaporator section of a refrigeration system; and divider elements adapted to fit together with the one or more fin elements to form a plurality of ice formation pockets. Processes for forming the assembly, as well as an ice machine incorporating the assembly, are also disclosed.

Abstract: A rocker joint for a power transmission chain is formed from a single pin d an associated link aperture. The pin has a substantially flat front surface and a convex back surface, with the back surface being defined by a plurality of radii. The pin is received in the aperture of the link such that the front surface of the pin engages and rocks on the curved surface of the link aperture. The back surface of the pin is movable in the aperture of the links as the surfaces move relative to one another when the chain articulates.

Abstract: A tour monitor system includes a portable tour monitor and a central programming/report generating computer. The tour monitor includes a bar code reader, an alphanumeric display, and an alphanumeric keyboard. The tour is organized into zones, each including a set of checkpoints, wherein each checkpoint is labeled by a bar code. The tour monitor is programmed to prompt the guard through the tour by displaying the names of successive zones. In addition, individual checkpoints can be designated as higher or lower priority checkpoints, and the tour monitor is programmed to alert the guard if higher priority checkpoints are missed, and to require the guard either to scan the missed higher priority checkpoint or to provide an override signal. The tour monitor also allows the guard to enter alphanumeric messages which are stored in combination with the scanned checkpoint codes in a log. This log is then transmitted to the programming/report generating computer for analysis.

Abstract: A still camera for recording a still image by making use of an electronic signal has a taking lens system incorporated in a camera body in such a manner that one end portion thereof is directed to an object to be photographed for making an image of the object to obtain the electronic signal; a light emitting portion of an electronic flash device incorporated in the camera body in such a manner that one end portion thereof is directed to the object for emitting a flash light toward the object; and a recording medium containing portion arranged between the light emitting portion and taking lens system.

Abstract: Method and apparatus provide effective application of plural component material from a plurality of air contained small streams, with stabilized stream formation, division and application and with a substantial reduction of VOC emissions in plural component applications, such as gel coat and wet-out applications in the manufacture of reinforced fiberglass articles. In the method, a flow of compressed air is delivered to an applicator and flows of the plural component materials are mixed and formed into a plurality of small, spaced streams extending from the applicator. The flow of compressed air is divided into a plurality of air flows that are directed about the plurality of small, spaced streams of plural component materials and generally adjacent and parallel to the streams. In apparatus for this method, a source of compressed air is provided and an applicator is adapted for connection to the source of compressed air and one or more sources of the plural component materials.

Abstract: An apparatus and method for producing a label which includes the use of an infrared dryer operating at 1200.degree.-1500.degree. F. to cure the adhesive before the underlying ink is re-wetted and runs.

Abstract: A two-way rotary lock is disclosed of a type suitable for use in locking a sliding door of an automative vehicle in either an open or closed position. This lock includes a lock body that defines first and second recesses positioned on opposed sides of the lock body to receive first and second strikers mounted to the side frames which define the door opening. A latch plate is rotatably mounted within the lock body, and this latch plate defines first and second tangs. Pivotal movement of the latch plate causes the first and second tangs to block the respective recesses and thereby capture the respective strikers in place. A single lock mechanism is used to secure the latch plate in position, and appropriate linkages allow either an inside handle or an outside handle to be used to release the latch plate and thereby release a captured one of the strikers from the lock body.

Abstract: A drilling machine includes a drilling substructure skid which defines two spaced parallel skid runners and a platform. The platform supports a draw works mounted on a draw works skid, and a pipe boom is mounted on a pipe boom skid sized to fit between the skid runners of the drilling substructure skid. The drilling substructure skid supports four legs which in turn support a drilling platform on which is mounted a lower mast section. The legs are pivotably mounted both at the platform and at the drilling substructure skid and a pair of platform cylinders are provided to raise and lower the drilling platform. A pair of rigid, fixed length struts extend diagonally between the platform and the substructure skid away from the platform such that the struts do not extend under the platform and obstruct access to the region under the platform. Preferably, the pipe boom skid mounts a pipe boom as well as a boom linkage, a motor, and a hydraulic pump adapted to power the pipe boom linkage.

Abstract: An optical bowling pin detector wherein light reflecting from the top five inches of each pin is directed to a linear array of photosensitive devices by an anamorphic lens. The detector is positioned so it can view all the bowling pins without moving.

Abstract: A method for promoting dental health in which chewing gum is employed to alter the oral environment to provide natural resistance to dental caries. The method involves chewing a sugarless gum which contains a relatively insoluble, hydrophobic food-grade organic acid, preferably adipic acid. Chewing of the gum gradually releases the acid from the gum at a desirably linear rate over a period of approximately 20 to 30 minutes. Release of the acid from the gum into the mouth stimulates an increase in salivary flow rate greater than that experienced during chewing a non-acidulated chewing gum, resulting in increases in salivary electrolytes and basic proteins and in the concentration of natural salivary bicarbonate to a level in excess of that necessary to neutralize the acidulant being released from the gum. The excess of natural salivary bicarbonate raises the salivary pH and plaque pH and neutralizes microbially-formed lactic acid responsible for tooth demineralization and resultant dental caries.
