Patent GB-2284094-A (GB)
Title: Microwave component having tailored operating characteristics and method of tailoring
Inventor: KORNRUMPF WILLIAM PAUL
IPC: H01P5/18
Filed: 1991-04-04
Abstract: The electrical operating characteristics of a microwave circuit are modified by providing a dielectric layer 330 on the circuit and a further conductive layer 328 in a pattern which modifies the electrical characteristics of an overlay responsive portion of the circuit in a manner which results in the overall circuit having a desired electrical operating characteristic within a tolerance. Adjustment of the operating characteristics of the circuit e.g. a buried stripline 312, 322, 324 may be done in an iteractive manner of measuring the characteristics, modifying the distribution of conductive material 328 and remeasuring the operating characteristics until satisfactory operating characteristics are obtained. Alternatively, the operating characteristics may be adjusted in an interactive manner in which the circuit is provided with power and appropriate signals and its operating characteristics are monitored during the process of selectively removing dielectric material with the removal process being controlled in accordance with the current electrical operating characteristics and being terminated when a desired set of operating characteristics is obtained. Further modification of the characteristics is achieved by direct connection of the layer 328 with the strip line 324 using via holes (not shown) drilled by laser through the lower layers and subsequent application of conductive coating when the layer 328 is provided. <IMAGE>

Title: Disk drive activity indicator
Inventor: BURTON JOHN SAWYER
IPC: G11B33/12
Filed: 1994-07-27
Abstract: A disk drive unit includes a monitoring circuit for monitoring current drawn by the disk drive motor. Amber and green light-emitting diodes (LEDs) L1, L2 are provided, for indicating whether the motor is active or quiescent. The monitoring circuit illuminates the amber LED L2 when the current is above a threshold value, indicating that the disk drive motor is active, and illuminates the green LED L1 when the current falls below the threshold value for a predetermined time, indicating that the disk drive motor is quiescent. This is particularly useful in disk systems comprising a large number of "hot-pluggable" disk drives, since it enables a service engineer to easily identify which disk units can be safely removed. <IMAGE>

Title: A battery charging circuit
Inventor: SUN PETER KA-TAI
IPC: H02J7/00
Filed: 1994-07-29
Abstract: A circuit for charging batteries B1 - B4 comprises means for supplying a charging current to each battery, load application circuits (400) for applying a load to each battery and control means comprising a main control unit (200), charging control circuit (300) and discharging control circuit (400) for connecting the charging current supply means and load applying circuits (400) alternately to the batteries. The circuit enables alkaline and nickel-cadmium batteries to be recharged. The main control unit initially measures the internal resistance of the battery and charging is prevented if the measured value exceeds a preset value. The circuit also monitors the load voltage to determine if the battery requires charging, charging being terminated when the charging voltage exceeds a preset value or when the rate of increase of the charging voltage is less than a preset value. <IMAGE>

Title: Multipulse processing of speech signals
Inventor: TAGUCHI TETSU
IPC: G10L19/10
Filed: 1994-12-02
Abstract: In a multipulse processing device for achieving a high encoding efficiency without using a high sampling frequency for an input signal and with a great degree of freedom given to positions of multipulses, an input speech signal is subjected by an LPC analyzer/processor 3 to LPC analysis of each analysis frame for extraction of LPC coefficients after sampling by an A/D converter 2. Multipulses are retrieved as a result of decision by a multipulse analyzer 20 with a degree of freedom given relative to sampling points of a sampled speech signal supplied through an auditorily weighting filter 4. Encoded by an encoder 41 and together with k parameters used as an example of the LPC coefficients, retrieved multipulses are multiplexed by a multiplexer 42 for delivery to a synthesis side. A multipulse waveform synthesizer 45 synthesizes a waveform by using decoded multipulse data and the LPC coefficients. <IMAGE>

Abstract: In accordance with the present invention, there are provided nucleic acids encoding human metabotropic glutamate receptor subtypes and the proteins encoded thereby. In a particular embodiment, the invention nucleic acids encode mGluR1, mGluR2, mGluR3 and mGluR5 subtypes of human metabotropic glutamate receptors. In addition to being useful for the production of metabotropic glutamate receptor subtypes, these nucleic acids are also useful as probes, thus enabling those skilled in the art, without undue experimentation, to identify and isolate related human receptor subunits. In addition to disclosing novel metabotropic glutamate receptor subtypes, the present invention also comprises methods for using such receptor subtypes to identify and characterize compounds which affect the function of such receptors, e.g., agonists, antagonists, and modulators of glutamate receptor function.
Patent GB-2300681-A (GB)
Title: Telescopic joint
Inventor: HELLER WILLIAM CHARLES KINGHAM
IPC: F16L27/12
Filed: 1995-05-10
Abstract: A telescopic joint (10) has inner and outer cylindrical members (20,30). The inner member (30) has a series of recesses (60,60') formed in it, located in one of which is an O-ring or garter spring (40). The end (50) of the outer member (20) is flared to provide a sloped interior surface. In use, the inner member is slid into the outer member until the ring (40) abuts this inner surface of the end portion (50). An axial force F applied to the joint causes the flared end portion (50) to compress the ring (40) in a direction F' both radial and axial, preventing the ring from shearing out of the recess (60) whilst providing a strong joint. The relative positions at which the inner and outer tubes (20,30) engage may be altered by removing the ring (40) from the recess (60) and rolling it into one of the other recesses (60'). The joint finds application in such articles as camera monopods and wading staffs.

Title: Self-centring polycrystalline diamond drill bit
Inventor: AZAR MICHAEL G
IPC: E21B10/56
Filed: 1995-12-20
Abstract: A self-centring drill bit includes a head portion 10 having a plurality of polycrystalline diamond compact cutting elements arranged in blades 20 that extend outwardly away from a surface of the bit. A cavity 24 is centrally located on the head portion and is formed between adjacent blade ends. The cavity 24 includes wall portions 26 defined by the blade end portions. The cavity 24 serves to house a core portion that is formed during drilling operation of the bit. The head portion is balanced to form and transmit a force from a designated wall portion to the core portion within the cavity. At least the designated wall portion 26 includes a low friction abrasion resistant surface 28. The cavity 24 includes a rigid element 30 extending outwardly away from the head portion to reduce the core within the cavity upon contact. The force transmitted to the core portion causes a countering force to be imposed by the core to the wall portion that keeps the bit aligned with its rotational axis and, thus prevents whirling. <IMAGE>

Title: A means for determining the x, y and z co-ordinates of a touched surface
Inventor: ATKINSON JOHN KARL
IPC: G06F3/041
Filed: 1997-01-31
Abstract: The force applied to the surface can be determine by the use of suitably plan force sensitive devices A,B,C,D which are positioned in such a manner that by a ratiometric comparison of their relative levels of measured force, it is possible to determine the relative position of the point of contact where the force is applied. In this manner it is possible to determine the x and y co-ordinates of the point of applied force relative to an arbitrary datum on the surface. Since the amount of force applied to the surface can also be determined by summing the individual forces measured by a number of suitably positioned force sensitive devices, it is possible to infer z axis information as related by the total amount of applied force. In this way x, y and z co-ordinate information can be inferred from the point of contact and degree of force applied to the surface. The force sensors are piezo-resistive devices (figs 3 and 4) and the system may be incorporated into touch screens or graphic tablets (figs 5 and 6).
