摘要:
A thermal applicator for medical use which is worn upon or applied directly to the body of a patient to modify its temperature for therapeutic treatment. The preferred embodiment of the present invention contemplates the utilization of a heat pipe having first and second ends and a length, the first and second ends communicating with first and second thermally conductive plates, respectively, the first thermally conductive plate configured to communicate with an exterior portion of the body of the patient and to provide localized thermal treatment, the second thermally conductive plate placed at an area removed from the area to be treated, and configured to accept, for example, an ice pack (or other thermal material or apparatus) to affect a change in the temperature of the second thermally conductive plate, cooling the second end of the heat pipe and allowing the heat pipe to cool the first thermally conductive plate, thereby providing localized cooling of the area to which it is applied. An alternative embodiment of the invention contemplates a heat source in lieu of the ice pack, wherein the second thermally conductive plate would function as an evaporator, thereby providing a reverse cycle in the heat pipe, for heating the area to be treated via the first thermally conductive plate. The present invention may be utilized for localized thermal application on various parts of the body, and several examples are illustrated, including an exemplary system to treat plantar fasciitis.

A height adjustment system for a paving screed apparatus and a method for adjusting the height of the endgates of a screed system are disclosed. In a disclosed system, the system includes an endgate coupled to a biasing element, such as a spring or a hydraulic cylinder and rod. The biasing element is coupled to an actuator. The actuator is linked to a controller. The biasing element is moveable between a compressed position and an extended position with a setpoint range disposed between the compressed and extended positions. The biasing element is also associated with a sensor for measuring vertical displacement of the biasing element, pressure or load on the biasing element with respect to the setpoint range.

A method and apparatus for monitoring energy data is also presented.
摘要:
The present invention is generally directed to an oral composition comprising a calcium phosphate salt and a combination of acids having differing solubilities in the oral cavity, for tooth mineralization or remineralization. The presence of a combination of acids in the oral composition acts to maximize the release of calcium and phosphate ions from the oral composition over an extended period of time, in order to promote the precipitation of enamel-like crystals on the surfaces of the teeth, or in subsurface regions therein.
摘要:
A confectionery product comprises a first side and a second side generally opposite to the first side; the second side comprising an abrasive surface that is suitable for scrubbing the top surface of a tongue within the oral cavity. In preferred embodiments the first side is smooth, and may be domed shaped and generally fit the roof of the mouth. The abrasive surface may be provided by 1) a formed, uneven surface, 2) by including abrasive inclusions in the composition making up the second surface, or 3) a combination of a formed, uneven surface and abrasive inclusions. The confectionery product is preferably a hard confectionery, but may also be a chewing gum product. A preferred confectionery product comprises a second side with a width and a length, the smallest of which is at least 1.6 times the product thickness. Preferred pressed tablets are made from a compressible composition and have at least one abrasive surface suitable for cleaning the surface of a human tongue in an oral cavity and have a hardness of between about 18 Kp and about 35 Kp.
摘要:
In a method for controlling the heat in an internal combustion engine for a vehicle with a coolant circuit and actuable devices for influencing the heat balance of the internal combustion engine, wherein a coolant temperature and further operating parameters of the internal combustion engine are recorded, the actuable devices are operated as a function of the coolant temperature and the further operating parameters of the internal combustion engine in such a manner that an output value for determining a control variable is provided by means of a basic characteristic diagram as a function of the rotational speed and the load on the internal combustion engine, and this control value is corrected by means of a controller as a function of the coolant temperature and/or the further operating parameters.
摘要:
An indwelling catheter arrangement includes a cannula, the proximal end of which starts from a receiver and the distal end of which has an opening, as well as a flexible catheter, which can be guided through the receiver and through the cannula opening. A guiding element extends during the placing of the catheter, the guiding element remaining in the catheter after the placement and being fixed in a defined position in relation to the catheter. This arrangement provides a catheter which has a desired flexibility and, simultaneously, cannot slip in an uncontrolled manner after placement.
摘要:
In a valve train of an internal combustion engine having a switchable support element (1), the lost motion spring (18) of the support element (1) is arranged axially offset next to the support element (1) while being coupled to an inner element (3) of the support element (1) by a crossbar (20). Due to this externally positioned spring (18), the support element (1) requires only a relatively small design space.
摘要:
An engaging and disengaging support element is proposed, having a compression spring (21) constructed as a so-called “lost-motion spring” that concentrically surrounds an inner element (5) that can be uncoupled. Because of this construction, a considerable amount of construction space is gained in the axial direction. Preferably, the support element (1) is provided with a hydraulic play compensation element (9).
摘要:
A tappet (1) for a valve drive of an internal combustion engine is so designed as to be switchable for different valve lifts and includes an outer circular ring shaped section (5) which encloses a circular section (6). Both sections (5, 6) are acted upon by cams of different lifts, and selectively interconnectable together by coupling elements (9). According to the invention, a juncture (12) for hydraulic fluid is positioned in the skirt (2) and extending from a feed bore (13) in the cylinder head (4) at a lowest point of the tappet (1), when viewed in direction of gravity, in order to install the tappet (1) in an extreme slanted disposition. In opposition thereto, a port (21) of the channel (27), following the juncture (12), is arranged at a highest section of the tappet (1), when viewed in the direction of gravity. Thus, after shut-down of the internal combustion engine, a reservoir (17) can empty only to the level of the port (21), so that the tappet (1) is sufficiently filled with hydraulic fluid when restarting the internal combustion engine.
