Abstract: Antenna for frequencies above the high-frequency band having one or more antenna conductors (6, 6a,b,c), in the form of wires, which are connected to one another in radio-frequency terms at one end, and an antenna connecting point (8), the antenna being arranged together with a heating panel in a windowpane, for example a motor vehicle window (1) with window heating. The heating panel is formed by heating conductors (5), in the form of wires, which are routed essentially parallel to one another and which are connected at the ends adjacent to the edges of the window in each case by a busbar (4a,b), running at right angles to the heating conductors, for supplying the DC heating current. The antenna conductors (6, 6a,b,c) are routed partially inside the heating panel, where they are at right angles to the heating conductors (5) to which they are connected in a low resistance manner in terms of radio frequencies at the intersection points (25) and thus, with the adjacent sections of the same, form an antenna surface (10) acting capacitively. A second part of the antenna conductors (7, 7a,b,c), in the form of wires, is connected in a low resistance manner in terms of radio frequencies to one of the first conductor parts and is routed at the other end to the antenna connecting point (8).

Abstract: A control device is disclosed which suitably controls the opera­tion of first and second fans in a heat collection type ventilation equip­ment. The heat collection type ventilation equipment comprises an air supply passage for introducing the outside air into the inside, a first fan disposed in the air supply passage, an air discharge passage for dis­charging the inside air to the outside and a second fan disposed in the air discharge passage. A heat exchanger exchanges heat between the outside air passing through the air supply passage and the inside air passing through the air discharge passage. A first sensor detects the temperature of the outside air and a second sensor detects the tempera­ture of the inside air. The control device compares the sum of the tem­peratures of the outside and inside air detected by the first and second sensors with a reference temperature and operates the first fan at an operating ratio below 100% whenever the sum of the temperatures of the outside and inside air is below the reference temperature.

Abstract: The invention includes apparatus and method for lubricating and cooling a workpiece (68), dies (60) or ironing rings (62,64,66), and punch (70) at the interface between the workpiece and such dies or ironing rings and punch in forming a workpiece into a hollow closed end cylindrical article. 
     A lubricant liquid phase is injected into a coolant liquid phase to form a "dispersion" prior to application to the metal-tool interface. Providing the lubricant as a dispersion in the coolant liquid phase rather than as an emulsion provides several advantages. The quantity of lubricant and the time of lubricant injection can be varied to control lubricity and, thus, friction. The invention makes it possible to achieve differential friction in the ironing process by having higher lubricity on the ironing die (low friction) and lower lubricity on the punch surface (high friction). Lubricities and cooling are controllable for the specific metal forming process employed to produce closed end hollow body containers. After application, the lubricant and coolant are separated, the lubricant filtered to remove debris, stored, and then reinjected to provide lubrication for the process.

Abstract: The enzyme alanine aminotransferase (ALT) is colorimetrically determined as the hydrogen peroxide obtained in the pyruvate hydrolysis reaction catalysed by the enzyme pyruvate oxidase which develops a colour read at 550 nm making use of a reagent composition buffered at pH comprised within 7.0 and 7.5 containing L-alanine, ketoglutaric acid, a source of inorganic phosphorous, the enzyme pyruvate oxidase, a system for revealing the hydrogen peroxide and optionally one or more co-factors which interact in the enzymatic reaction catalysed by the enzyme pyruvate oxidase. It is moreover described a method for the determination of the enzyme alanine aminotransferase making use of said reagent composition and of the surface antigen of the hepatitis B virus (HBsAg), by enzymeimmune assay, in the same serum specimen and in the same well of a microtitration plate. The method is particularly useful for checking the suitability of the blood intended for transfusions since it can be easily carried out with equipments and instruments widely used for the immunoenzymatic screening of infectivity. Furthermore it enables to test in the same analytical assay the two labels of hepatocyte infections necessarily researched in the transfusion centres on biological specimens and to select among the donors the most likely candidates to transmission of the NANB hepatitis virus.

Abstract: A frame buffer stores pixel data for each pixel. The pixel data are converted into color data according to color data at a corresponding address in a first look-up table (LUT). An overlay memory stores change data representing presence/absence of color change for each pixel and change pixel data. According to contents of change pixel data in the overlay memory, color data at a corresponding address in a second look-up table are read, thereby converting the change pixel data into color data. To display an image, data stored in both of the frame buffer and the overlay memory are read for each pixel. To perform color change, the change pixel data are used instead of the pixel data. When change data in the overlay memory indicate presence of color change, change pixel data are converted into color data with reference to the second look-up table. Then the color data are exhibited on a CRT display. Color change can be also performed by an address designating circuit which is provided in place of the second look-up table and is used for changing an address to be read with reference to the first look-up table.

When a request for setting a new call is originated, communication bandwidths of first and second transit lines (10-a, 10-b) on which exists a virtual path to form thereon a virtual channel for the call are checked for their margin enough to accept assignment of a bandwidth requested by the call, the first transit line lying between the cross-connect unit and an originating local switching unit and the second transit line lying between the cross-connect unit and a terminating local switching unit. If the first and second transit lines have a margin enough to accept the assignment of a bandwidth requested by the call, the virtual channel for the call is established on the virtual path and values of communication bandwidths assigned to the first and second transit lines are updated.

Abstract: A device and related method for coupling segments of an extended local area network (LAN) in such a way that message traffic employing inter-network protocols such as TCP/IP will be handled without the difficulties usually associated with bridges, and without the complexity and expense of full IP router capability. The device operates like a bridge for non-TCP/IP traffic. For TCP/IP traffic it operates in a bridge-like manner but maintains a database associating extended LAN segment addresses with port numbers in the device, so that packets can be automatically forwarded over a spanning tree connecting the network segments. A host computer in any network segment can address others in different network segments of the extended LAN as though all were in a single LAN. The device of the invention functions to block the flow of ARP messages and to generate ARP replies that render the device of the invention transparent to hosts within the extended LAN. The device is also transparent to true IP routers, which may still be used to effect communication with points outside the extended LAN.
