Abstract: A method and apparatus to produce an ion mobility signature representing a wood sample provides a method of comparing signatures to identify the species of the wood sample.  A method of producing an ion drift time signature representing a wood species comprises heating at least a portion of a wood sample at a temperature in the range of about 220 to 350°C to desorb and produce trace vapours from the wood sample, ionize the trace vapours at a temperature in the range of about 220 to 350°C, pulse ions through a gate into a drift region, measure the time of arrival of the ions and the ion flux for each pulse, with a collector electrode, located at the end of the drift region to produce an ionic signal, and amplify and average the ionic signal to provide an ion drift time signature for the wood sample.

Abstract: A transient electromagnetic apparatus for use in detecting irregularities on conductive walls of containers forms a multichannel distributed system and includes at least one transmitting antenna, at least one transmitter unit, plural receiving antennas, plural receiver units, and a computer for controlling the transmitter and receiver units. The receiver units each include elements that suppress noise in the received signals. Each receiver unit has a preamplifier, first and second low pass Bessel type filters, a gain ranging amplifier, and an A/D converter. The gain ranging amplifier receives feedback from the output of the A/D converter and provides increased small signal resolution.      Each receiver unit also rejects common mode noise with a choke and balanced input impedances in the preamplifier.      The apparatus allows an arbitrary number of receiving antennas, receiver units, and even transmitting antennas, and transmitting units, so that the apparatus can be configured to a variety of containers. Each receiver unit has control logic for controlling the electronics therein and memory for storing data for transfer to the computer. The apparatus includes a median filter for filtering out sferics noise.

Granted: 1993-08-10
Abstract: ABSTRACT OF THE DISCLOSURE         In the production of foamed plastic articles using a screw extruder, it is known to introduce a gaseous foaming agent into the plastic while the latter is passing through the extruder.  It has been found that a foamed thermoplastic with pores or cells of uniform size and distribution can be produced by passing a gaseous foaming agent, e.g. nitrogen gas through a central passage extending substantially the entire length of the extruder screw, discharging the agent into the thermoplastic proximate the discharge end of the extruder, and mixing the foaming agent with the plastic immediately prior to discharge of the mixture into a mold.

Abstract: ABSTRACT OF THE DISCLOSURE       The coffee brewing machine can be used to prepare alter-natively normal coffee or espresso coffee and comprises a boi-ler having a temperature control. The cold water is fed to the boiler by means of a water pump with adjustable feed rate. Two different brewing members are used for the preparation of the two kind of coffees, namely a sieve holder and a filter support which are connectable via a mounting and supporting flange to the boiler. A mode switch is assigned to the mounting and sup-porting flange which automatically changes the mode of opera-tion of the coffee brewing machine upon exchanging the brewing member. Thereby, the feed rate of the water pump and the tem-perature of the hot water are adapted to optimize the condi-tions for preparing either normal coffee or espresso coffee.

Title: Method of adapting a mobile radio communication system to traffic and performance requirements
Inventor: OESTLUND ANDERS KARL
IPC: H04B7/26
Filed: 1990-08-24
Granted: 2001-10-30
Abstract: A method in a mobile radio communication system for adapting the system and communication to prevailing traffic and performance requirements. According,to the invention a mobile station inserts information on particular nodes in its messages transmitted to a base station in response to an invitation message from the base station. The codes indicate whether a message is new or retrans-mitted and/or message age. The base station receives radio signals in time slots identified in its invitation message and estimates for each time slot based on radio signals received in the time slot whether the time slot is empty ar busy, or whether the time slot is empty or correct. For each message received and understood the base station retrieves the code. The retrieved codes and the number of emty/busy/correct slots enable the base station to estimate prevailing system traffic and performance.      Estimations on prevailing traffic and performance are used to control system parameters such as number of time slots following an invitation message.

Abstract: In this bogie (1) the static and dynamic forces are absorbed by the frame (5). In designing the body unit fitted on the frame (5), therefore, only the unit's own weight and the passenger load are significant, thus facilitating the use of extremely lightly-built vehicle bodies. The bogie (1) consists of single-wheel drive units (2), a longeron (3) interconnecting them, on each long side of a drive (4), the frames (5) bearing the end unit (9) and a drive control (6) for turning the single-wheel drive units (2) horizontally depending on the curves. A wheelless central unit (10) is supported on each short side on the bogie (1) via a joint (8). A push-pull device (7) engages with the short side opposite the joint (8). There are no lobbies inside the vehicle which is thus freely accessible. In the region of bogie there are recesses in the form of wheel-boxes in which certain parts of the bogie (1) are arranged.

Abstract: In each terminal connected to an optical bus a narrow pulse synchronized with the rise of a pre-synchronizing pulse appended to the head of the one digital signal TXN of Manchester-biphase signals, a narrow pulse synchronized with the rise of each pulse of the other Manchester-biphase digital signal TXO and a narrow pulse occurring every fixed period of time during the duration of each pulse are produced, and these narrow pulses are converted into optical signals, which are provided as an optical pulse train to the optical bus.  In each terminal optical pulses received from the optical bus are converted into an electric signal, which is separated into its leading pulse and the subsequent pulses, and the synchronizing pulse is produced in synchronization with the leading pulse and the subsequent pulses are each converted into a pulse of a fixed width to regenerate the signal TXO, and the regenerated signal TXO is polarity inverted and is then combined with the pre-synchronizing pulse to regenerate the signal TXN.

IPC: H03J7/04
Filed: 1990-12-18
Granted: 2000-10-17
Abstract: Analog circuit parts in an integrated circuit, for example filters, can be equalized by a control current by equalizing an additional reference circuit part, whose equalization must be verified externally, with this control current. By using a suitably designed horizontal frequency oscillator whose equalization must also be verified, this reference circuit part can be dispensed with even in known TV receivers. Using additional control circuits in the integrated circuit, fine equalization of the various circuit parts can be carried out automatically by adding a small correction control current to each control current. As a result, the control circuits are free from problems related to background noise, interception range and component tolerances. Equalization of analog bipolar or CMOS integrated circuits.
