Title: Data processing
Inventor: BOUSFIELD BRUCE MARTIN
IPC: G01M99/00
Filed: 1986-08-08
Abstract: To facilitate real-time monitoring of dynamic parameters, e.g. for testing of gas turbine aeroengines, at least one data acquisition card (A) functions in parallel with a data processing card (B). Card (A) includes components (16, 18) which receive analogue signals (12a), sample and digitise them, and use them to continually update a microprocessor ring buffer (20). Blocks of signals are transferred from the buffer to a second microprocessor (30) on card (B), which processes the data using a suitable algorithm. Processed data is passed to a third microprocessor (40) on card (B) for data reduction using a further algorithm, the reduced data being output for evaluation and/or recordal, e.g. in a host computer (C). Microprocessor (40) controls the dynamic range and sampling rate of the data input to the buffer as well as data transfer between cards, and gives priority to updating the buffer. In a preferred embodiment card (B) can be connected to sixteen or more acquisition cards (A), which it interrogates sequentially. <IMAGE>

Title: Synchronizing signal generating apparatus for PAL system
Inventor: HIEDA TERUO
IPC: H04N5/06
Filed: 1986-11-13
Abstract: Synchronizing signals for a PAL television system are provided by two oscillators 1 and 4, respectively to produce a color subcarrier frequency fSC and a horizontal synchronizing frequency fH. The oscillator outputs are divided by dividers 3 and 7 respectively in each case to yield a signal which is (11 x n/8)fV, where n is a positive integer and fV is the vertical synchronizing frequency. The resultant two frequencies are supplied to a phase detector 8, the output from which is used to control the frequency of one of the two oscillators 1 or 4. Because of the subcarrier frequency the first divider 3 divides by 64489. Other embodiments (Figs. 2-5) use first oscillators with higher frequencies, namely 2, 4 and 5 nfsc. The value of division by divider 7 is correspondingly changed. In the sixth embodiment (Fig. 6) and third oscillator at a multiple of fv is used for phase comparison of both oscillator outputs, both oscillators being frequency controlled. <IMAGE>

IPC: G01N15/14
Filed: 1987-02-23
Abstract: A device for analysing the proportions of differently coloured portions in articles and in particular for analysing the proportions of lean meat and fat in meat products. Red and green filters 6,7 are placed in different parts of the field of view of a monochrome television camera disposed above a continuous black conveyor 3 carrying pieces of meat 4 to be analysed, whereby the TV picture has parts corresponding respectively to input light received via the two filters. Two equal reference frames 8,9 are defined in these two parts of the TV picture. The red filter enables all meat to be easily distinguished from the conveyor. The green filter allows darker fat to be distinguished from pink lean meat. A measuring cycle is established wherein the total area of the TV picture within the two reference frames 8,9 exceeding predetermined levels is measured alternately in each frame so as to accumulate the total area of meat and the total area of fat passing the camera. <IMAGE>

Patent GB-2215403-A (GB)
Title: Rotary compressors
Inventor: WILLIAMS MICHAEL RHYS
IPC: F04C18/22
Filed: 1988-03-10
Abstract: A rotary compressor of Wankel type comprises an epitrochoidal stator (4) and a trochoidal rotor (14) which rotates within the stator about its own axis which itself rotates about an axis through the centre of the stator. The tips (16) of the rotor contact the stator defining three compression cells whose volume progressively increases and decreases as the rotor rotates. Each compression cell communicates with an inlet (20) as its volume increases and with an outlet (24) including a non-return valve (26) as its volume decreases. Leakage between ares of high and low pressure is prevented by movable seals (21) mounted in slots (19) at the stator cusps and biased by springs (23) into sliding contact with the rotor. Leakage may be further prevented by the provision of movable seals at the tips of the rotor or by injecting oil at 34 into the air being compressed. The oil is subsequently separated from the compressed air and recycled. <IMAGE>

Title: Controlling velocity of magnetic disk reader
Inventor: NISHIMURA MAKOTO
IPC: G11B5/55
Filed: 1990-06-15
Abstract: A velocity signal creation circuit 15 generates velocity signals SV to indicate a movement velocity of a servo head 3, according to the servo information SI which the servo head reads from a magnetic disk 1. These velocity signals are supplied to an amplifier 25 that has a gain of one time and an amplifier 26 that has a gain of K times (K>1). These output signals are supplied to a switching circuit 27 which selectively outputs the velocity signal amplified by either one of the amplifiers. A CPU 13 supplies the servo head with the velocity command value to indicate a movement velocity for the servo head to reach the target position when it moves to the target position. It also multiplies the velocity command value to K times when the distance between the current position and the target position of the servo head reaches the previously set remaining movement distance N. Furthermore, it outputs the control signal B to the switching circuit. When the control signal B is supplied, the switching circuit outputs the K times velocity signal to the servo system to control the servo head position. <IMAGE>
