Abstract: A method and apparatus for automatically and dynamically determining a list of frequently called telephone numbers for abbreviated dialing or speed dialing. The method and apparatus maintain a list of each telephone number dialed, either manually or by abbreviated dialing, over a period of time. This list is periodically updated to remove infrequently used telephone numbers. The list is also sorted such that the most frequently used telephone numbers will be displayed as a top set or page thereof. The apparatus includes a telephone set which has multiple display areas where one set or page of telephone numbers available for abbreviated dialing is displayed. Each display area is associated with and adjacent to a respective switch. A paging switch which causes the display of one or more subsequent sets or pages of the abbreviated dialing list may also be included. To make a telephone call using the abbreviated dialing apparatus, the user actuates the switch adjacent to the display area displaying the frequently dialed number or a label (name) corresponding to the frequently dialed number. From that switch actuation, the apparatus will read the corresponding number to be dialed from memory and automatically dial the number. This abbreviated dialing list is self starting and self maintaining, the user never needs to personally 'program' the telephone set. This method apparatus may include the use of a customer premise equipment and/or a telecommunication switch.

Inventor: HARTUNG HANS-GEORG
IPC: B21B37/16
Filed: 1996-03-29
Granted: 2007-06-12
Abstract: A method arid an apparatus for an anticipatory thickness control in foil rolling by using characteristic lines stored in a process control computer of the individual manipulated variables (for example, strip tensions, rolling speeds) for various operating points (conditions of operation) or by using an on-line operating physical computing model, also in combination with a monitor control. The method includes the steps of determining the thickness deviations of the foil at the entry side of the roll stand and of compensating the thickness deviations by an anticipatory thickness control. The apparatus includes a thickness measuring device between the running-off reel and the rolling mill or the roll gap of the roll stand. The thickness measuring device is connected to a superordinated process control computer, Following the thickness measuring device is arranged a tensioning unit which serves to change the travel path of the foil strip between the running-off reel and the roll gap. For example, the tensioning unit elongates the travel path.

Abstract: Oil and water based drilling muds, together with other wellbore contaminants such as pipe thread sealants and lubricants are displaced from the well (10) and the wellbore surfaces are cleaned by a system of four serially pumped fluid pills. The first stage fluid pill is a weighted spacer having an alkyl polyglycoside surfactant, a dispersant, a weighting agent and a viscosifier. The second stage pill is a drive fluid formed by water and a viscous polymer gel such as clarified xanthan gum having a viscosity/shear rate characteristic which minimizes mixing of the drive fluid pill with the displacement fluid pill. A buffer fluid pill comprising completion brine is interposed between the drive fluid pill and a fourth stage comprising a wash fluid pill using an organic solvent or a caustic alkyl polyglycoside as a final cleaning stage. The densities of the pills are controlled to minimize mixing and fingering.

Title: A method for treating organohalogen compound, and an apparatus thereof
Inventor: TAMATA SHIN
IPC: A62D101/22
Filed: 1996-06-13
Granted: 2001-01-23
Abstract: A method for treating an organohalogen compound by destroying the compound harmlessly supplies the organohalogen compound, a carrier gas such as air, and steam in controlled amounts.  These gases are heated to a temperature in a designated range by combustion of hydrocarbon fuel.  The exhaust gas after catalytic destruction is cooled in a container having the catalyst.  This exhaust gas passes through apparatus for treating undestroyed organohalogen compound by adsorption.  The exhaust gas is desorbed and recovered during the operation of the catalyst, and the undestroyed compound is destroyed by the catalyst.  The arrangement increases the efficiency of the destruction of organohalogen compounds and the durability of the apparatus employed.

Abstract: A hinge, preferably made of plastics material, has two connecting arms (5.1, 5.2) arranged at a distance (k1, k2) apart which connect a closure part (1) and a closure body (2). Each connecting arm has at least one relatively rigid intermediate part (4) and a coupling element (7) which executes a relieving movement. The coupling element (7) protrudes movably from the corresponding hinge part (1, 2). Two bending regions (9.1, 10.1; 9.2, 10.2) which form an angle with each other delimit the intermediate part (4). The connecting arms (5.1, 5.2) may be parallel or non-parallel to each other or be bent in one plane. When folded out, the connecting arms snap into the shape of the arch of a bridge, without large material elongations, a compensating movement deviating the excess stress laterally in the dead centre. As a result of an additional bending region (11.1, 11.2, 12.1, 12.2), with or without a snapeffect, in each connecting arm, the opening angle is substantially increased andtri-stable or multi-stable opening or closing, as desired, is achieved.

Abstract: A drill includes support pads for supporting and guiding the drill in the drill hole. The support pads are foamed as parallelepiped-shaped cemented carbide bodies which each have two wing-shaped protrusions on their longitudinal sides. In a corresponding way, the drill head of the drill includes recesses with two bulged parts on the long sides. This gives the support pad a determined axial position and strengthens the support pad at the weakening caused by the central hole.  Further, the support pad can be turned half a revolution if one of its ends becomes damaged since the end spaces do not have to function as abutment surfaces.

Title: Dab receiver, apparatus and method for a format conversion of a dab data sequence
Inventor: SPIERO RICHARD CEES
IPC: H04J11/00
Filed: 1996-09-25
Granted: 2006-11-14
Abstract: A DAB receiver, an apparatus and a method are introduced for converting a first sequence of data having a fixed frame structure, wherein locations within the frame are reserved for predetermined data types, into a second sequence of data, having a different frame structure. The data belonging to the respective data types are grouped in separate sequences with a frame type identifier attached to the sequences for identifying the different sequences. This allows an easy identification of the different sequences of data within the second sequence without the need of prior knowledge of the exact location of the sequences within the second sequence. An example of such a conversion is the conversion of the channel decoder output of a DAB receiver into a format suitable for embedding in the IEC958 format.
