Title: Method for recycling asphalt material
Inventor: ZICKELL THOMAS J
IPC: F26B11/02
Filed: 2000-05-26
Granted: 2009-06-30
Abstract: An asphalt based material recycling system and method is used to recycle asphalt materials, such as asphalt shingles and tar paper that include granules, fibers or other particles. The asphalt material is simultaneously heated and milled in a heated milling apparatus, such as a heated ball mill, to reduce the asphalt material including granules to a fine mesh in suspension in liquid asphalt. Excess moisture is removed from the asphalt material being recycled by continuously venting the heated milling apparatus. The heated milling apparatus preferably includes a rotatable milling vessel rotated at an acute angle with respect to the horizontal plane and having an opening that provides continuous venting. The shape of the milling vessel allows the liquid level inside the milling vessel to have a liquid head above the outlet region of the milling vessel, for facilitating milling. The rotatable milling vessel includes a plurality of mixing members, such as rods or paddles, extending from an interior surface to enhance milling and to pull the asphalt material being recycled under and into the liquid slurry. The asphalt material recycling system further includes a filter apparatus for filtering reduced asphalt and removing foreign objects therefrom.

Granted: 2004-01-20
Abstract: There is provided an image rejection mixer (100) for downconversion of an incoming signal to a lower intermediate frequency signal, using the absolute difference of frequencies between the incoming signal and the local oscillator signal. The image rejection mixer is set up to accept and downconvert incoming signals at two discrete frequencies fh and fl, where the local oscillator frequency is positioned mid-way between those frequencies fh and fl. There are two signal paths (S1, S2) in the image rejection mixer, either one or the other of which is chosen by positioning a controllable single pole, double throw (130) switch into one of its two switch positions. The output of the switch is led to a mixing element (116), from which an intermediate frequency signal is derived. The first of the two signal paths (S1) from the input to the image rejection mixer to the mixing element has a bandpass characteristic centred at one or the other of the two input frequencies of interest; the other signal path (S2) has a bandstop characteristic centred at the same frequency. By choosing one or the other of the signal paths, an incoming signal at a designated one or the other of the incoming signal frequencies may be downconverted, and the image signal and any noise at that image signal frequency will be rejected.

Abstract: In a transceiver in a wireless communications system, data is transmitted from the transceiver to subscriber units, wherein each subscriber unit has a requested transmit power and an allocated transmit power, and wherein the allocated transmit power is based upon the requested transmit power. A request for an additional power allocation (200) is detected, wherein such additional allocation causes a total requested power to exceed a maximum transceiver power (220). In response, allocated transmit power is limited for a minimum number of selected subscriber units (222) needed to reduce a total transceiver transmit power below the maximum transceiver power (220).

Abstract: Generally, the present invention provides a device and method for accurately locating a multi-well plate at a plate-support location, e.g., a work surfac e, of an automated laboratory machine, such that one or more acting members of the machine, such as an array of pipette tips, optical sensors, or the like, can accurately address and operate on the individual wells. Interior and/or exterior surface regions of one or more wells of a multi-well plate are used as the primary plate features engaged by locating structure of the machine. In one particular embodiment, one or more upwardly tapered projections extend from a plate-support surface of a plate-handling machine for mating engageme nt with the exterior surface regions of one or more wells. In another embodimen t, the exterior surface regions along one or more well bottoms are engagingly received within bores, or other receiving structure, formed on the plate- support surface of a machine. In a further embodiment, one or more downwardl y extending projections depend from an acting-member support, along with the acting members of a machine. Introduction of the projections into some of th e wells of a multi-well plate serves to align the acting members with the plate's other wells. A biasing assembly can be used to press together the engaging surface regions of the wells and the locating structures of the machine.

Abstract: An electrothermal zoned de-icing system for an aircraft employs a heat-conducting tape bonded to the leading edge of an aircraft structure. The heat-conducting tape has a spanwise parting strip area (122), and first and second ice accumulation and shedding zones. The tape comprises a non-metallic electrical and heat conducting layer consisting of flexible expanded graphite foil laminated to an outer heat-conducting layer, in which the thickness of the flexible expanded graphite foil layer in the parting strip area (122) is always greater than the thickness of the foil layer in either of the ice accumulation and shedding zones (123, 124). Therefore, the parting strip area has a decreased electrical resistance, a greater flow of current, and becomes hotter than the zones in which the foil layer is thinner. Because the flexible expanded graphite foil is a monolithic structure that may be shaped, sculptured or layered to form different thicknesses in different areas, only a single control mechanism for a single set of electric terminals is necessary to produce desired watt densities and temperatures in the parting strip and ice accumulation and shedding zones.

Title: Temperature control for multi-vessel reaction apparatus
Inventor: CHU DANIEL Y M
IPC: C12Q1/68
Filed: 2000-07-11
Granted: 2006-10-03
Abstract: Temperature control in a rectangular array of reaction vessels such as a thermal cycler such as is used for PCR procedures is achieved by use of a temperature block that is in contact with a combination of Pettier effect thermoelectric modules and wire heating elements embedded along the edges of the block. The elements can be energized in such a manner as to achieve a constant temperature throughout the array or a temperature gradient. Further control over the temperature and prevention of condensation in the individual reaction vessels is achieved by the use of a glass (or other transparent material) plate positioned above the vessels, with an electrically conductive coating on the upper surface of the glass plate to provide resistance heating.

Granted: 2012-09-18
Abstract: L'invention concerne un matériau de construction (40) comprenant un fibro-ciment (10) stratifié en plâtre (20) pour former un composite stratifié en une seule partie. Ce composite en une seule partie présente des propriétés de résistance au feu, aux chocs et à l'endommagement de surface améliorées, sans pour autant présenter l'épaisseur et le poids excessifs des systèmes à deux parties. En outre, compte tenu de la réduction de l'épaisseur, le matériau de construction composite préféré est plus facile à couper, et également plus facile et plus rapide à installer que les systèmes à deux parties. En outre, la construction du fibro-ciment et du plâtre en un stratifié à une seule partie supprime le besoin d'installer deux parties différentes d'un matériau de construction, ce qui simplifie l'installation générale. Un mode de réalisation traite d'un composite stratifié de 5/8'' d'épaisseur comprenant un panneau de plâtre de 1/2'' stratifié en une feuille de fibrociment de 1/8'' d'épaisseur. Ce composite stratifié présente une résistance au feu de 1 heure, lors des essais selon la norme ASTM E119.
