Patent GB-2184849-A (GB)
Title: Calibrating microwave integrated circuit test systems
Inventor: EDDISON IAN GREGORY
IPC: G01R1/073
Filed: 1986-06-13
Abstract: Apparatus for calibrating an integrated circuit test system comprises a substrate having a substantially planar array of thin film components (1-9) formed thereon. The components are provided with contact pads which, for each component, have a spacing which enable the components to be engaged by the tip of a coplanar waveguide probe of the test system. Such apparatus permits error correction to be achieved under computer control, resulting in scatter parameter measurements to be made with reference planes at the tips of the probe, obviating the need for sophisticated but error prone de-embedding techniques.
Patent GB-2179810-A (GB)
Title: Dynamic range control of a signal
Inventor: MCNALLY GUY WILLIAM WHITSEY
IPC: H03G11/00
Filed: 1986-10-03
Abstract: A dynamic range controller consists of a multiplier 14, Fig. 1 controlled by a side chain 18 comprising: a level detector 20, a log circuit 22, a threshold subtractor 24, a non-linear circuit 26, a slope multiplier 28, and an antilog circuit 30. The level detector 20 comprises a peak detector (40, Fig. 4) with separate attack and decay time constants, in which the decay time constant is itself dependent upon the output of an r.m.s. detector (60). The slope and threshold values vary such that two or more different threshold/slope factor pairs are used for different sections of the signal amplitude so that the device provides different DRC functions (limiter, compressor, expander, or noise gate) for the different amplitude sections (Fig. 6). A smoothing recursive filter (Fig. 9) is included between the antilog circuit 30 and the multiplier 14, and has a time constant which varies as to whether the detector is in the attack or the recovery mode, this mode determination being made with a degree of hysteresis. The response time constant of the filter is between one-sixth and two-thirds of that of the level detector 20. <IMAGE>

Title: Fire optic ionizing radiation detector
Inventor: STEPHENSON IAN
IPC: G01T5/08
Filed: 1986-12-16
Abstract: The ionizing radiation detector comprises an optical fibre, and a detection system 14 to sense radiation induced luminescence emitted from both ends of the fibre. The optical fibre can be spooled, to provide a discrete detector or the optical fibre can be installed around an area to provide an integrated detector. To calibrate the fibre to allow for radiation induced increase of attenuation, a second, identical, optical fibre is subjected to the same environment and its attenuation is measured between source 16 and detector 15. A third detector 18 may monitor the output of source 16. The fire may be similar to a conventional optreal communication fibre having a core surrounded by a sheath of lower refractive index. <IMAGE>

Title: A dual purpose hoe
Inventor: MCCLUSKEY JOHN
IPC: A01B1/08
Filed: 1987-03-26
Abstract: The hoe comprises a body (1) for a handle to fit, a blade and stem (2), and a hinge bolt unit (3). The blade stem fits between lugs on the underside of the body and is fixed by a hinge bolt passing through the lugs and stem. Thus fitted the stem is below the body and the blade is at the bottom of the stem. The blade is the working part of the hoe. The hinge allows the blade and stem an angular movement so that in the push position the hoe is a push hoe and when the blade and stem are moved the other way the hoe assumes the draw of Dutch hoe position. The hinge is a friction fit and eliminates slackness. When the hoe is moved in the desired direction, pushed or pulled, the blade immediately assumes the correct position for use. <IMAGE>

IPC: G06N3/02
Filed: 1988-05-27
Abstract: A digital computer system wherein any required item of data, instead of being retrieved from a memory by entering a keyword, is generated by performing a calculation on the entered keyword. The calculation comprises operating on the entered keyword with a function which is a polynomial in several variables and has the property that, when of sufficiently high degree, every entered keyword which resembles one of the items more closely than any other is transformed into that item. The calculation is designed so as to be implementable by means of a network of interconnected processing units (i.a. a so-called neural network) which effectively operates as a distributed, content-addressable memory.

Title: Radiation monitor
Inventor: BENTLEY ANTHONY
IPC: G01T1/02
Filed: 1988-08-22
Abstract: A device for attachment to an X-ray film cassette to indicate whether or not the film has been exposed to X-radiation comprises a diode or other semi conducting device which changes state on exposure to X-radiation generating a control signal which is used to alter the display status of a liquid crystal display (24). A latch circuit (16) is used to retain the altered display even after exposure to X-radiation ceases. An accumulator circuit (18) stores the total X-radiation dosage for display after the exposure ends. The circuit is powered from a nickel cadmium cell (28), the power supply circuit of which incorporates a micro-switch (26). The micro-switch is positioned such that when photographic film is present in the cassette and the cassette is closed, the film bears against the micro-switch to close the latter, thus allowing power to be supplied to the circuit. As a result, in the absence of film, the display is blank giving a clear indication that there is no film in the cassette. <IMAGE>

Preferably, a tension meter (9) for the cable is disposed between the intermediate sheave and the bow sheave. This enables the bow sheave (10) to be disposed at a high position with respect to the water surface compared with the known ship.
