A high speed programmable logic controller is taught. Briefly stated a Programmable Logic Controller having memory, a microprocessor and a Co-Processor are operatively interconnected using a Harvard style architecture therefore having separate data and instruction busses. The Co-Processor acts as a Boolean Processor and is therefore able to simultaneously perform instruction fetches and executions...

A gaseous oxygen electrochemical sensing system sustains inter-electrode ionic conductivity by the use of a combination of an hydrophilic coating layer on a gas-permeable barrier or separation membrane to supply sufficient moisture to the electrolyte of an electrode system to activate the sensor and sustain proper operation.

A method capable of manufacturing wax matrices efficiently in large quantities at once characterized in that a multiscrew extruder is used to achieve the object.

A low depth nestable tray (20) for holding cans of similar capacities and body diameters but with varying top and bottom rim diameters. The tray comprises floor (50), a band (30) around the periphery of the tray and columns (70) interconnecting the band (30) to the floor (50). Nesting ledges are disposed on columns (70) and on corner posts (100) of the wall structure. The ledges are equal in heigh...

In a dynamic frame length slotted ALOHA system the synchronising signals are transmitted by a base station at different frequencies (each having a period equivalent to a multiple of the time slot period). The different frequencies denote different frame lengths and the central stations detect these frequencies and select a frame length accordingly.

Ultrasonic energy is used to release a stored drug and forcibly move the drug through the skin of an organism into the blood stream. A housing (81) includes a cavity (67) defined by an assembly of ultrasonic transducers (65) and separated from the skin by a polymeric membrane (69) that stores the drug to be delivered. The ultrasonic transducer assembly includes a flat, circular ultrasonic transduc...

An external retaining device may be used for securing an enteral feeding tube in a desired location with respect to a person's skin. The feeding tube passes through a first hole in the retaining device, then is guided through a 90 DEG , bend following a radius of curvature such that the feeding tube is not kinked, and then passes through a second hole in the retaining device, with the longitudinal...

A multi-layered film material having a structure wherein a protective layer, a composite film comprising a polyvinyl alcohol film or a film of an ethylene/vinyl acetate copolymer saponificate and a silicon oxide deposition layer formed on the former, and a heat-sealable polyolefin layer are laminated. In this case, each of the layers is transparent and the silicon oxide layer is disposed on the si...

Solid phase hybridization and competitive PCR assays for detecting and determining the concentration of target nucleic acids are disclosed. PCR target and competitor products are immobilized via a coupling agent attached to the primer, alkaline denatured, separated from sense strands and detected and quantified via hybridization with labeled probes. Alternatively, solid phase PCR is performed with...

The state of the extracellular matrix of discrete tissue subsegments can be determined via an approach that combines microdissection, reverse transcription and polymerase chain reaction. Using this approach, a positive correlation between a fibrotic condition and alterations in messenger RNA levels of matrix components provides the basis for (i) the diagnosis of a fibrotic disease and (ii) the mon...
