Title: Measuring the quality of silvers, rovings and textile fibre threads
Inventor: ENDERLIN ROBERT
IPC: D06H3/00
Filed: 1990-09-13
Abstract: A thread (11) is passed through apparatus comprising a capacitative sensor (12) for measuring mass regularity, a stretching device (13) for evaluating cohesive forces, breaking force and breaking elongation and a device (20) for measuring the force applied to the thread. The device (13) comprises two pairs of rollers (17a, 17b, 18a and 18b) driven at different circumferential speeds V1 and V2. By varying the distance D between the pairs of rollers the breaking force is determined. A third pair of rollers (19a, 19b) can be included in the stretching device. A second capacitative sensor 23 allows the mass regularity after stretching to be determined. The average count is determined by weighing apparatus (14, 26). The apparatus serves for improved control of the spinning process. <IMAGE>

Title: Battery charging circuit with temperature-responsive cut-out
Inventor: YANG TAI-HER
IPC: H02J7/00
Filed: 1991-04-05
Abstract: A battery charging circuit is provided with a thermal cut-out (TSI) whose normally closed contacts are in series with the main terminals of a thyristor (SCR1). The thyristor is switched ON on commencement of battery charging by the charging of a capacitor C1 (which remains charged even when the contacts of cut-out TS1 open as a result of the battery temperature rising on completion of charging). Consequently thyristor SCR1 remains latched OFF even if the contact of cut-out TS1 close, and can only be turned ON again by disconnecting battery B1, which enables capacitor C1 to discharge via a diode CR1.

Title: Improvements in orreries.
Inventor: BULBROOK GEORGE LEE
IPC: G09B27/02
Filed: 1992-09-09
Abstract: An orrery is driven by a spring motor having a first gear (42) integral with a lever (44) for winding the motor, the first gear (42) meshing with a second dual gear (46) which drives an arm for rotating a planet (18, Figure 1) about a star (14), and an elongate helical spring (50) connected between the lever and the second gear, said spring being expanded and curved when the lever is rotated to wind the motor, and wherein the speed of drive of the arm when the lever is released to allow the spring to contract and straighten is governed by the transmission chain between the spring motor and the rotating planet on the end of the arm. The inertia of the spinning earth (18) is employed as a governor. Thus the speed of operation of the orrery is controlled by appropriate selection of the mass of the earth (18). <IMAGE>

Patent GB-2278984-A (GB)
Title: Speech presence detector
Inventor: BISHOP ANDREW
IPC: G10L25/78
Filed: 1993-06-11
Abstract: A speech detection system for detecting the presence of speech in an audio input signal 1 derived from a predetermined environment such as an HF communication system. Algorithms are used at 4 to extract salient features from a digital signal obtained by analogue to digital conversion at 3 from a received audio signal 1. The algorithm outputs are applied to a neural network 5 which is trained by back propagation to distinguish between speech and other signals. The output of neural network 5 controls a switch or relay 6 to pass an audio signal for the duration a speech is detected. Delay 6 is for ensuring that the initial part of speech is not lost. Filter 10 removes high frequency components introduced by DAC 9. A post processing stage may follow neural network 5 for effective control of switch 6. The algorithm processor 4 may receive a digital audio signal directly as well as via an FFT stage. <IMAGE>
