An impact resistance spreading helmet is disclosed. The helmet includes a frontal section configured to interface with the forehead of an individual and extend upward over the cranium; a medial section for extending over a portion of the cranium rearward of the frontal section; an occipital section for extending rearward from the medial section and configured to cover a portion of the neck of the individual; a first compressible structure disposed between the frontal section and the medial section; and a second compressible structure disposed between the medial section and the occipital section. The interface between the frontal section and the first compressible structure is disposed at an angle vertical to a force direction perpendicular to the frontal section above the forehead of the individual.

A side skirt system for reducing drag on a trailer includes a side skirt wall configured to be coupled to one side of the trailer to extend below a side wall of the trailer along a length of the trailer. A mounting bracket assembly of the system is coupled to the side skirt wall and is configured to be coupled to a floor assembly of the trailer. The mounting bracket assembly is configured to tilt laterally outwardly and laterally inwardly with respect to a generally vertical axis parallel to the side wall of the trailer.

The invention provides improved methods and apparatus for control using field and control devices that provide a virtual machine environment and that communicate via an IP network. By way of non-limiting example, such field device can be an “intelligent” transmitter or actuator that includes a low power processor, along with a random access memory, a read-only memory, FlashRAM, and a sensor interface. The processor can execute a real-time operating system, as well as a Java virtual machine (JVM). Java byte code executes in the JVM to configure the field device to perform typical process control functions, e.g., for proportional integral derivative (PID) control and signal conditioning. Control networks can include a plurality of such field and control devices interconnected by an IP network, such as an Ethernet.

A unique structure for an indoor exercise bike that provides strength in its design, as well as the flexibility to create an aesthetically appealing frame structure. The monocoque frame design, including two symmetrical halves joined together, forms a very strong, light shell that can take on a variety of shapes and sizes. The seat structure, handlebar structure, drive train and support platforms are all able to be readily attached to the primary frame structure to provide an exercise bicycle that is sturdy, easy to manufacture, and light enough to easily move when necessary.

A fosfomycin plus tobramycin combination formulation for delivery by aerosolization is described. The concentrated fosfomycin tobramycin combination formulation containing an efficacious amount of fosfomycin plus tobramycin is able to inhibit susceptible bacteria. Fosfomycin and tobramycin are formulated separately in a dual ampoule such that when reconstituted, the pH is between 4.5 and 8.0 or as a dry powder. The method for treatment of respiratory tract infections by a formulation delivered as an aerosol having mass medium average diameter predominantly between 1 to 5 μ, produced by a jet or ultrasonic nebulizer (or equivalent) or dry powder inhaler.

A concrete mold device for vertically forming a concrete panel comprises a plurality of concrete forms for collectively defining a mold cavity for receiving an uncured concrete mixture therein. The concrete forms include: a pair of opposing side wall forms configured to define side wall surfaces of the mold cavity; and a pair of opposing end wall forms, configured to define end wall surfaces of the mold cavity. An elongate lower support gasket has an upper surface configured to define a bottom surface of the mold cavity, the lower support gasket having gasket side walls configured to abut against at least a portion of each of the side wall forms to provide a seal between the lower support gasket and the side wall forms to retain the concrete mixture within the mold cavity. Reinforcing structure is associated with the lower support gasket to increase a load-bearing capacity of the lower support gasket.
摘要:
A method for bi-casting a turbine rotor may include applying an oxidation resistant coating to individually cast rotor blades, and bi-casting the coated blades into a dual alloy blade ring, wherein the oxidation resistant coating prevents formation of an oxide scale on the surface of the rotor blades during bi-casting and allows diffusion bonding of the rotor blades to the blade ring. The oxidation resistant coating may comprise a platinum group metal or alloy thereof.

A current regulation device employs an interface connector and a temperature controlled current regulator including a current path operably integrated with the interface connector. In operation, the interface connector establishes a simultaneous electrical communication of a current source and a load device to the current path of the current regulator. The temperature controlled current regulator facilitates a regulation of a flow of a current through the current path at a base regulation temperature as a function of an analog differential between the base regulation temperature and a measured operating temperature indicative of the flow of the current through the current path.

An electrical one-piece double-ended receptacle contact includes a first and a second socket contact portion at opposed axial ends of the receptacle contact for receiving a first and a second respective mating pin contact. A compliant middle portion interconnects the two socket contact portions. The tube wall has an axial slot extending over its length. A first and a second circumferential slot divide the tube length. The circumferential slots are axially spaced from each other by a middle section of the tube. Each of the circumferential slots has a first circumferential end between the middle section and the associated one of the socket contact portions, and a closed second circumferential end which has a predetermined circumferential distance from the axial slot so that the remaining wall portion between the axial slot and the closed second circumferential end of the respective circumferential slot forms a web connecting the middle section to the associated one of the socket contact portions. The axial length of the middle section and the circumferential and axial extensions of the webs are dimensioned to allow three axis compliance of the contact, at least reducing relative movements between the socket contact portions and the mated pin contacts.
