Patent CA-2304049-A1 (CA)
Inventor: SIEBERT LESTER
IPC: B29C69/00
Filed: 1999-07-16
Abstract: An apparatus for attaching a reclosable fastener (28) to a web (16) of flexible material for use with a host packaging machine to form a reclosable container. The attaching apparatus is operatively connected to and driven by a programmable motor and function controller in cooperative relation with the host machine and guides the web of flexible material from which the containers will ultimately be formed along a first path through the attaching apparatus. A supply of reclosable zipper-type fasteners (28) is also provided, and the fasteners are guided along a second path of the apparatus. Individual zippertype fasteners are removed from the fastener supply path and disposed in juxtaposition to a segment of the flexible material in overlying relation to a cut which has been formed through a predetermined segment of the flexible material. The individual fastener is then sealed to the flexible material in overlying, surrounding relation to the cut, and the web, with the reclosable fastener attached thereto, is then passed to the host packaging machine for forming, filling, sealing and separating a reclosable container.

Title: Direct reduction method and rotary hearth furnace
Inventor: TANAKA HIDETOSHI
IPC: F27D99/00
Filed: 2000-05-03
Abstract: Raw materials, including a metal oxide and a carbonaceous material, are supplied into a rotary hearth furnace. Then, the raw materials are heated and reduced by burners, which are arranged to cause a strong stirring action for an atmosphere around the raw materials, in an early reducing period that is defined as a period during which 70 - 80 % of a total amount of a flammable gas generated from the raw materials is generated. In a latter period subsequent to the early reducing period, the raw materials are heated and reduced by burners arranged to cause a weak stirring action for an atmosphere around the raw materials, whereby a metal is manufactured. With the present invention, productivity can be improved and the fuel consumption per unit product can be reduced.

Inventor: FIATO ROCCO ANTHONY
IPC: C01B3/44
Filed: 1998-10-30
Abstract: A process for making a synthesis gas comprising H2 and CO in the presence of a reforming catalyst comprising a supported non-noble Group VIII metal catalytic component from a feed including a low molecular weight alkane, and preferably methane as in natural gas, O2 H2O and CO2 without catalyst deactivation is achieved by partially oxidizing and steam reforming the feed in the presence of the catalyst. The feed H2O to hydrocarbon carbon mole ratio is less than 2.  The mole ratio of the combined feed CO2 and H2O to hydrocarbon carbon ranges from 0.5 - 2.5 and that of the feed H2O to CO2 ranges from 0.35 - 6. Synthesis gas having H2 to CO mole ratios less than 2:1 and even less than 1.5:1 are easily achieved with net CO2 consumption, which also makes the process environmentally beneficial.

Title: Mounting of rotors of generators in a magnetic field
Inventor: MATYSCAK KAMIL
IPC: H02K7/09
Filed: 2000-05-29
Abstract: The present invention relates to an arrangement for the mounting of rotors of generators, in particular hydrogenerators, in a magnetic field. In this case, the mounting is effected via at least one magnetic bearing, which is arranged in the region of the rotor rim and the pole windings. As a result, the force due to the weight of the rotor is picked up directly at the point of origin. The at least one magnetic bearing may consist of either a separate radial bearing and a separate thrust bearing or a combination of radial and thrust bearings. The at least one magnetic bearing may be arranged both above and below the rotor and directs the force due to the weight into the foundation. Due to the use of magnetic bearings, the overall efficiency is increased on account of a reduction in bearing losses.      In addition, the rotor may be designed more freely; the compactness required hitherto is no longer absolutely necessary.

IPC: B01F7/16
Filed: 1999-03-24
Abstract: An internal batch mixing machine (20) includes a mixing chamber and oppositely driven first and second rotors (22, 24). The first rotor has a pair of lobes located in its first and third quadrants (96, 98; 100', 102'), while the second rotor has a pair of lobes (120, 122; 124', 126') located in its second and fourth quadrants. One of the lobes (96, 98) of each pair is longer than the other, and extends downstream at an acute co-helix angle toward the other lobe (98, 116'). The leading end of the long lobe is near one end of its rotor, and the short lobe is at the other end. Material adjacent the longer lobe are pushed away from its end and toward the other end of that rotor.  Additionally, the trailing ends of each pair of lobes forms a space which causes confluent material to be squeezed between the trailing ends thereby adding turbulence to further mix the material.

Abstract: A novel contact structure and method for a multilayer gettering contact metallization is provided utilizing a thin layer of a pure metal as the initial layer formed on a semiconductor cap layer. During formation of the contact structure, this thin metal layer reacts with tile cap layer and the resulting reacted layer traps mobile impurities and self-interstitials diffusing within the cap layer and in nearby metal layers, preventing further migration into active areas of the semiconductor device . The contact metallization is formed of pure metal layers compatible with each other and wide the underlying semiconductor cap layer such that depth of reaction is minimized and controllable by the thickness of the metal layers applied. Thin semiconductor cap layers, such as InGaAs cap layers less than 200 nm thick, may be used in the present invention with extremely thin pure metal layers of thickness 10 nm or less, thus enabling an increased level of integration for semiconductor optoelectronic devices. In addition, because pure metal layers arc used in the ohmic contact, fewer impurities are introduced in the formation of the contact than with prior art alloy contacts.

Title: Method and system for broadcasting a digital data signal within an analog tv signal using orthogonal frequency division multiplexing
Inventor: WU YIYAN
IPC: H04N7/08
Filed: 2001-04-12
Abstract: The present invention relates to a method and system for transmitting digital data within an analog TV signal. Digital data are received from a data source. The digital data are then multilevel encoded and a plurality of data symbols in dependence thereupon is provided. Each of the plurality of data symbols is modulated in frequency domain onto a carrier of a plurality of carriers such that each carrier carries a different data symbol. The modulation step is based on an OFDM method and is performed using a serial to parallel converter. After modulation a digital data signal is provided. Some carriers of the plurality of carriers are turned off in the modulation process in order to shape the spectrum of the digital data signal such that the spectrum of the digital data signal comprises notches at locations coinciding with locations of spectral components in the vestigial sideband of the video carrier of the analog TV signal. The width of the notches is determined such that degradation of the analog TV signal due to the transmission of the digital data within the analog TV signal is substantially reduced. After IFFT transformation into time domain and D/A conversion the digital data signal is combined with the analog TV signal by inserting the digital data signal in the vestigial sideband of the video carrier. The digital data broadcasting technique according to the invention is capable of transmitting digital data within an analog TV signal at a substantial higher data transmission rate than prior art systems without causing any degradation to the picture quality noticeable to non-expert viewers.
