摘要:
Cooling water is circulated through the heating water jacket of a gas sterilizer during the initial gas pressurization phase to reduce the temperature rise within the sterilization chamber caused by the heat of compression of the gas.

Mechanism for cooling individual cylinders of an engine, using low pressure air bled from an engine supercharger. Special passage structures are provided to guide and confine the air during its passage across external surfaces of the engine cylinders. After performance of its coolant function, the air may be passed into the supercharger outlet passage. The mechanism is especially useful for cooling engines in armored military vehicles in that a minimum number of air openings are formed in the armored hull structure; engine cooling is achieved without sacrificing the integrity of the armor envelope.

The application describes a control pendant for controlling a multi-segment patient table to assume a variety of different positions or configurations. The pendant has safety features including automatic shutoff of power to the keys under selected conditions and backlighting of the keys when power is being supplied (e.g., when keys are operational) to provide improved visibility in low-light environments. The control pendant further has an ergonomically effective shape and key board layout. An icon representing the table and its segments is located on the keyboard, and the keyswitches are arranged with respect to the icon to facilitate rapid and accurate visual identification of keys which operate particular table segments.
摘要:
A dental handpiece sterilizer includes a sterilization chamber with an internal manifold system having outlet connectors into which dental handpieces can be plugged. A sterilant vapor introduced to the manifold flows through the dental handpieces coupled to the manifold and into the interior of the chamber so that it contacts the exterior surfaces of the handpieces before exiting the sterilant chamber.

This invention relates to structural aggregate pigment products that are cationic, and have improved wet-end retention. A method for converting anionic pigments to cationic pigments is also provided. More particularly, a structural aggregate pigment comprising a clay and/or titanium dioxide or other particulate components, and a functional microgel made from silicon and aluminum or zinc gel formers and a gelling agent such as calcium chloride, can be cationized by adding an effective amount of modified or unmodified epichlorhydrin dimethylamine condensate to a slurry of the structured pigment. The resulting cationic pigments have superior papermaking characteristics and a much improved retention.
摘要:
Apparatus and methods for detecting pressure changes within the chamber of a pressure vessel are disclosed. The apparatus includes a pressure transducer which is gauge-referenced to atmospheric pressure and has bi-directional capability of determining pressure changes above and below atmospheric pressure. The transducer is structured to provide frequency output and is therefore connected directly to a microprocessor. The microprocessor includes structure programmed to compensate for variations in existing ambient atmospheric pressure.

The present disclosure relates to nucleic acids comprising a sequence of SEQ ID NO: 1. The nucleic acid may be an isolated DNA and/or may be in the form of a plasmid or an expression vector. It may also be comprised in a microorganism. The nucleic acid may further comprise sequences that encode a protein. The self-replicating expression plasmid comprising a DNA sequence of the disclosure may be used to produce one or more protein. The production of one or more protein by a plasmid of the disclosure may be controlled by temperature and/or chemical induction. The disclosure also provides methods of obtaining high yields of proteins and methods for purifying such proteins, such as the LdK39 protein or a fragment thereof.

摘要:
The present disclosure relates to an image capture device and a technique for capturing an image. The technique includes configuring an image capture device in a learning mode for sensing at least one variable in the device's surroundings and defining a normal state of the at least one variable. Further, the technique includes initiating image capture upon detecting a transition of the at least one variable from the normal state to a new condition, wherein the transition exceeds a predetermined threshold level, and redefining the normal state to the new condition.

The present invention relates to chemical delivery systems and methods for delivery of liquid chemicals. In one embodiment, the present invention relates to systems having multi-reservoir load cell assemblies for delivering chemicals used in the semiconductor industry. In one embodiment, the present invention provides a multi-reservoir load cell assembly, including a controller, a buffer reservoir, a main reservoir, one or more load cells, coupled to the assembly and to the controller, operable to weigh the liquid in the reservoir(s), a plurality of supply lines, each supply line having a valve and connecting one of the supply containers to the main reservoir, and a gas and vacuum sources for withdrawing the liquid from the assembly when demanded by the controller and for refilling the assembly from the supply containers.
摘要:
A dispense head assembly includes a bung adapter, a body receiver, and a dispensing body. The bung adapter inserts into a drum. The body receiver selectively inserts into the bung adapter, and the dispensing body selectively inserts into the body receiver. A single, unobstructed, uniform-diameter flowpath routes fluid from the drum into a chamber within the body receiver. A movable piston within the chamber selectively blocks fluid flow between the fluid flowpath and a dispense opening on the dispensing body. The body receiver and the dispensing body are key matched, for safe and rapid coupling and decoupling.
