Abstract: This invention involves a new type of feedthrough-plug member for metal halide HID lamp using PCA envelopes. The construction of the lamp housing consists of a PCA  envelope and specially designed axially graded alumina-metal cermet multi-layers to eliminate cracking in cermet or PCA due to thermal stresses arising from thermal expansion mismatch. The fills are metal halides such as Na-Sc-I, rare earth halides, Hg, Sn, and inert gases. The PCA vessel and directly sealed cermet-feedthrough assemblies allow the metal halide lamps to operate at high wall temperatures with better lumen output, color temperature, and CRI.

Abstract: (1) A doubly oriented silicon steel sheet having excellent magnetic characteristics in two directions, i.e. in a rolling direction and in a direction perpendicular to the rolling direction, and most suited for use as material for cores of small-sized transformers, and (2) a method for manufacturing the same. The doubly oriented silicon steel sheet as mentioned above in (1) is characterized in that: Si and Mn are contained in amounts which satisfy a predetermined formula of relation; an average crystal grain is as large as 1 to 8 times the thickness of the sheet as measured on a cross section parallel to the surface of the sheet; and at least 60% of all crystal grains have a size of X/3 to 3X, where X is an average grain size. In the doubly oriented silicon steel sheet, preferably, crystal grains having a crystallographic orientation difference within ~15 degrees from a cubic orientation of {100}<001> occupy an areal percentage of not less than 70%, or the thickness of a surface oxide layer of the steel sheet is not greater than 0.5 µm. The method for manufacturing a doubly oriented magnetic steel sheet as mentioned above in (2) includes the steps of hot-rolling and cold-rolling steel containing C in an amount of 0.02% to 0.2% and Si and M in amounts satisfying a predetermined formula of relation, wherein annealing is performed at a temperature not lower than 750°C and through quick application of heat during cold rolling; and the obtained steel sheet is annealed under reduced pressure through use of an annealing separator. In this method for manufacturing a doubly oriented magnetic steel sheet, preferably, a rolling reduction is 40% to 85% in cold rolling performed before and after intermediate annealing.

Abstract: A method and system of utilizing advanced intelligent network services for capturing and recording dial-around call information is provided. Dial-around calls are calls directed to a telecommunication services provider other than the services provider designated by the owner or operator of the originating telecommunications device, such as a pay telephone. When a public switched telephone network effects a "dial-around" of a prescribed telecommunication services provider at a pay telephone, accounting records generated by the local telecommunication services provider do not identify that the call originated at a pay telephone. Thus, important billing and asset management data are lost to the pay telephone operator. The method and system of the present invention utilize advanced intelligent network services to recognize dial-around calls and to produce a record for the pay telephone operator which will identify and record billing and utilization information for dial-around calls. The method and system may be used without the need for expensive and time consuming hardware and software retrofit of each local switch through which each pay telephone operator operates.

Title: Floor care machine
Inventor: STEIN THOMAS
IPC: B24B7/18
Filed: 1999-12-13
Granted: 2009-07-14
Abstract: A floor care machine realized in the form of a floor polishing machine contains a driven pad, the height of which pad can be adjusted automatically to adjust the application pressure to take the characteristics of the floor into consideration. For this purpose, between the driving element and the driven element, there is a transmission element which forms a torque regulator. For this purpose, the driven element can be rotated with respect to the driving element opposite to the working direction of rotation and can also be displaced axially, whereby the transmission element with a clamping element automatically regulates the displacement and rotation, thereby acting as a torque regulator to regulate the height of the pad with respect to the floor as a function of the torque.

IPC: H04L12/56
Filed: 2000-08-03
Granted: 2004-03-23
Abstract: A method is described for solving traffic engineering problems in a network In one aspect, the invention is used in a network that has at least one QoS  service class and at least one class of service that is not a QoS class. Bandwidth is allocated to service routes in the QoS service class so as to optimize a figure of merit such as network revenue. Then a new allocation is made so as to minimize network usage without departing too far from the optimal value of the figure of merit. A  residual network consists of that bandwidth that remains unallocated, on each link of the network. Bandwidth for non-QoS traffic is allocated to mutes on the residual network.  In a second aspect, the invention involves the use of optimization techniques to allocate bandwidth among service routes in one or more service classes in response to a set of demands in each class. The demands are calculated so as to take into account an effective bandwidth associated with the pertinent class, and so as to make allowance for the stochastic behavior of the traffic demands that occur in practice.
