Patent GB-2305035-A (GB)
Title: Open-drain SCSI driver with power-down protection
Inventor: OBERHAUSER JOHANN SILVESTER
IPC: G06F13/40
Filed: 1995-08-23
Abstract: An open-drain bus driver, for example for coupling signals 25 from a device to an SCSI bus 15, is slew rate limited by Miller capacitor 28. The power supply potential of the device is fed to node 80 so that when the device is turned off the bus potential is fed through PMOS transistor 40 to turn on the clamping transistor 50. This prevents undesired turn-on of driver transistor 20 by capacitive coupling of bus signals to the gate of that device.

Title: Muffler securement in a motor compressor unit
Inventor: BIAGIO ALFANO
IPC: F04B39/12
Filed: 1995-10-27
Abstract: A reciprocating hermetic motor compressor unit comprises a compressor cylinder head (18) with a recess (20) for receiving an end portion (21) of an induction muffler (22). A spring (25), placed in the recess between the muffler end portion (21) and the head, pushes that end portion against a valve plate (17) when the head is fixed to the cylinder (15). This means that the inducted gas passes directly into the cylinder without leakage into the interior of the compressor casing. <IMAGE>

IPC: E21B47/08
Filed: 1995-09-22
Abstract: An improved technique for determining the thickness of a member, especially pipe such as fluid-filled casing in an earth borehole, includes the following steps: directing a pulse of ultrasonic energy toward the inner surface of the pipe, and receiving and storing, as a function of time, signals representative of ultrasonic energy reflected from the inner surface of the pipe; determining, from the stored signals, the arrival time of the initial echo from the inner surface; determining, from the stored signals, the arrival time and the amplitude of a first candidate initial echo from the outer surface of the pipe; performing a reverse search on the stored signals to determine, from stored signals at times earlier than the arrival time of the first candidate, the arrival time and the amplitude of a second candidate initial echo from the outer surface; comparing amplitudes of the first and second candidates, and selecting, based on the comparison, one of the first and second candidates as the actual outer surface echo; and determining the thickness of the pipe from the arrival time of the actual outer surface echo and the arrival time of the inner surface echo. Using this technique, the earlier arriving candidate can be properly identified as the actual outer surface echo, even when the later arriving candidate has a greater amplitude.

Patent GB-2334187-A (GB)
Title: Quadrature modulator with automatic compensation
Inventor: JEPSEN RENE PIHL
IPC: H03C3/08
Filed: 1998-02-04
Abstract: Automatic compensation is provided for DC offset or gain assymetry of the modulator. The modulator comprises an amplitude envelope detector (205) connected to the modulator output. The amplitude signal at the output of the envelope detector (205) is fed to a sampler (207) and the samples are subsequently processed in an error generator (209) deriving an error signal. The error signal is filtered in a filter (211) before being applied to a compensator (201, 203) in each quadrature channel which modifies a characteristic of the modulator in response to the error signal. Typically an error signal is obtained by dividing the samples into two or more categories according to the corresponding data values and generating a difference between the samples in the two categories. Sampling of the amplitude signal is determined by a controller (213) in order to sample in a fixed relation to the timing of the baseband I- and Q-channels.

Title: A linearizing arrangement with predistortion and feedforward where the predistorter provides a reference for the feedforward
Inventor: KENINGTON PETER
IPC: H03F1/32
Filed: 1999-07-28
Abstract: The lineariser 1 comprises a digital signal processor (DSP) 100 for reducing distortion of the output of non-linear RF power amplifier 200. The DSP 100 implements a predistorter process 102 which predistorts the input signal to amplifier 200 in such a manner as to counter distortion imposed by the amplifier. Feedback from the amplifier output is sampled at 212 to provide a feedback signal for controlling the predistortion process. Additionally, a feedforward signal is combined with the amplifier output at 216 to further reduce distortion therein. The feedforward signal is derived by subtracting the input signal, at 112, from feedback from the output of amplifier 200 (which may contain residual distortion). The vector modulator 114 conditions the result of the subtraction process 112 to produce the feedforward signal. To ensure maximum cancellation of distortion in the output of amplifier 200, the vector modulator is adapted using feedback from the output of amplifier 200 (removed at 218) which is correlated with a reference signal produced by distorter 102. The reference signal contains components which correspond to some or all of the intermodulation distortion components which can be generated by amplifier 200.

Title: Method for oxidizing of organic compounds in water
Inventor: HERTRAMPF JOACHIM
IPC: C02F9/00
Filed: 1993-05-10
Abstract: Organic substances in biologically pretreated waste water are oxidised by ozonising with an ozone-containing gas in at least two reaction vessels (1, 2) connected in series and UV irradiation in a UV reactor (5). To reduce the size of the reaction vessels and decrease the specific ozone consumption, the reaction vessels through which the waste water successively flows are operated at pressures increasing from vessel to vessel. The ozone-containing gas flows through the vessels in counter-current to the waste water. The introduction of the ozone-containing gas from one reaction vessel to the subsequent reaction vessel proceeds as a result of the pressure drop. <IMAGE>
