Title: Quality driven voice channel selection in a cellular telephone system using idle voice channel signal strength measurements
Inventor: WARD TORBJORN
IPC: H04W36/20
Filed: 1997-02-18
Granted: 2005-01-25
Abstract: Each base station (14) in a cellular telephone system includes a signal strength measurement device (23) operable to tune to and make signal strength measurements on not only the voice channels assigned to other cells, but also on its own voice channels. The measurements on the own voice channels provide an indication of injected interference useful in making quality driven voice channel assignments during either call set-up or hand-off. In a conventional analog cellular system, the signal strength measurement device comprises the base station signal strength receiver (24) measuring on own idle base station analog voice frequencies. In a time division multiple access (TDMA) cellular system, the signal strength measurement device comprises the base station location verification module (30) measuring during idle time slots on digital voice frequencies.

Abstract: The magnetic circuit of synchronous compensator plant is included in an electric machine which is directly connected to a high supply voltage of 20-800 kV preferably higher than 36 kV. The electric machine is provided with solid insulation and its winding(s) is/are built up of a cable (6) intended for high voltage comprising one or more current-carrying conductors (31) with a number of strands (36) surrounded by at least one outer and one inner semiconducting layer (34, 32) and intermediate insulating layers (33). The outer semiconducting layer (34) is at earth potential. The phases of the winding are Y-connected, and the Y-point may be insulated and protected from over-voltage by means of surge arresters, or else the Y-point is earthed via a suppression filter. A procedure is used in the manufacture of a synchronous compensator for such plant, in which the cable used is threaded into the openings in the core for the magnetic circuit of the synchronous compensator.

Abstract: A cutter element (65) having a substantially flat wear face (63) and leading compression (64) and trailing tension (66) zones, wherein the leading compression zone (64) is sharper than the trailing tension zone (66). Sharpness is defined as either a smaller inside angle at the intersection of a pair of planes or as a smaller radius of curvature. The cutter element of the present invention experiences reduced stress on its trailing portion in the direction of cutting movement and therefore is less subject to extreme impact damage and cyclic fatigue. The present invention can be applied with particular advantage to heel row cutters (60), but can also be applied to cutters in other rows that primarily ream the borehole corner. The present cutter element can be constructed so as to have a positive or negative rake angle at its leading compression zone, or to have any of a variety of shapes, depending on the characteristics of the formation in which it is to be used.

Abstract: The apparatus makes it possible to change a desired sample volume - even during operation - in a simple manner without mechanical intervention, with any accumulation solids of a sample contained in a sample collecting vessel being avoided, so that a sample representative of the medium is obtained.      The apparatus comprises a control unit which controls a pneumatic control gear and switches a pump by means of which the medium is drawn into a sample collecting vessel via a hose or tube used as a suction line. A detection unit incorporated in the suction line signals the presence of the medium to the control unit, which then controls the time period for taking the desired volume of the sample. The sample volume obtained is drained off into a sample container via a drain device.

Title: Sender-defined time for reporting on the status of a sent message or of the message's recipient
Inventor: MOHLER DAVID S
IPC: G06Q10/10

Abstract: The sender of a message is able to specify to the recipient's messaging system or to the sender's own messaging system a reply time at which the sender wishes to be informed of whether or not the recipient has accessed the sent message. The reply time is included in the message. Upon occurrence of the response time, the recipient's messaging system checks if the recipient has accessed the message, and if not, whether the recipient's present schedule is available. It then sends a reply, with the schedule if it is available, to the sender. Upon occurrence of the response time, the sender's messaging system checks if a reply has been received from the recipient, and if so, whether it indicates that the message has been accessed and whether it contains the recipient's schedule. It then notifies the sender accordingly. The schedule preferably contains information that enables the sender to contact the recipient by other means.

Abstract: A mounting for mounting an article onto a support comprising upper and lower mounting members. Seating surfaces provided between the members retain the members in assembled relationship with the members immovably registered together in a first plane. Three spaced mounting member registration projections provide, in the assembly, contact between the mounting members in three spaced and staggered positions on opposite sides of one of the mounting members, and registration to hold the members immovably together in a second plane. Spring-loaded locking is provided to hold the members together when assembled. Preferably the registration projections are provided on one member upon guide surfaces which are converging and inclined towards a respective seating surface. Guide surfaces on the other member are correspondingly converging and inclined. The convergence and inclination causes the projections to force the seating surfaces together to hold the members in the first plane while the projections themselves hold the members together in the second plane. One or other of the seating surfaces may have seating projections to engage the other seating surface. The invention is particularly applicable for use on weapons for withstanding sudden violent or vibrational forces and for quick release while permitting reassembly and while ensuring that settings such as calibration and boresighting settings are not altered.

Title: Siphoning device for use in liquid basting and separation
Inventor: PORTER JERRY
IPC: A47J37/10
Filed: 1999-09-17
Granted: 2004-07-06
Abstract: The siphoning device, with the measuring indicators, is used for liquid-liquid separation. The body member has an outlet with an open tip; the outlet can have a peripheral rim with notches proximate the open tip. A two way liquid valve contoured to approximate the contour of the interior affixed to the liquid valve extends through and beyond the open tip of the outlet. Pressure on the stem places the valve in an open position and permits liquid to be discharged. An air pump interacts with the body to expel air and draw in the liquids. Generally the air pump is a flexible bulb with a one-way air valve to restrict air flow into the hollow body while permitting air flow out. The hollow body can be in two parts which are removably connected to one another.  The travel of the liquid valve within the hollow body is limited by stops.

Abstract: Subject of this invention is a process for the chemical synthesis of polynucleotides having totally or partially random sequences, based on the utilization, as synthesis monomer units for the random sequence part, or presynthetized mononucleotides and dinucleotides. Said synthesis is carried out on separate supports, so that on each of those supports is alternated at least one reaction cycle wherein a mixture of said dinucleotides is bound, with at least one reaction cycle wherein a mononucleotide is bound, and that in a preferred embodiment at the end of the n cycles required for a colon synthesis, the supports are mixed and then redivided into one or more reaction containers. The resulting polynucleotides are such that, for the random sequence part, each trinucleotide unit is fit to match only a limited number of colons, predefined for each unity in number and sequence, and the genetic co de degeneracy effects can thus be eliminated. Figure 1 shows the chemical structure of the dinucleotides utilized as monomer units for th e synthesis of colons forming the final sequence.
