Title: Tractor bonnet having "wrap around" intake openings for cooling air
Inventor: ISHIIZUMI SEIICHI
IPC: B60K11/08
Filed: 1994-11-04
Abstract: It is known for tractor bonnets to include front mounted radiator grilles. These grilles are subject to clogging by wisps of straw, etc. This requires the operator to stop the machine to unclog the grille. The tractor according to the invention has external grilles which wrap around the left and right sides of the frontal bodywork, and therefore have a larger surface area than grilles confined to the front wall. Air passes through these grilles relatively slowly, hence debris does not readily stick to them. They comprise upper grille 55, attached to bonnet 52, and intermediate grille 54 and lower grille 56, attached to fixed bodywork 51. Numerals 33 and 34 denote rubber seals. Numeral 53 denotes a headlight mounting frame. Internal grilles 51c and 52c are not subject to clogging, because of the filtering effect of the external grilles. Grilles 55 and 56 may be made of flexible material, which may be stored flat. Upper and lower fan shrouds are also disclosed (fig. 5). <IMAGE>

Title: A double superhet radio receiver
Inventor: HASLER RAYMOND JENSEN
IPC: G01S1/00
Filed: 1992-07-13
Abstract: A radio receiver for receiving signals from both the GPS and GLONASS satellite navigation systems has at least two successive frequency down-converters 14, 18 arranged to be fed by respective local oscillator signal source 24, 26. A single frequency synthesiser provides the local oscillator signal sources. In order to tune the receiver to a number of different receiver frequencies separated by equal frequency increments corresponding to a predetermined frequency spacing of a series of transmission channels, the frequencies of the local oscillator signal sources are variable in respective series of frequency increments associated with the equal frequency increments separating the receiving frequencies, and the frequency of the first of the said sources is a constant integer multiple of the frequency of a second of the said sources. The predetermined frequency spacing is integer divisible by the frequency increment of the second source, and the intermediate frequency at the output of the down-converterfed by the second source is constant The relationship between the local oscillator frequencies is provided by a binary divider 32, at least a portion of which may form part of the synthesiser loop 30. Modifications to the synthesiser loop are described Figs 2 and 3. <IMAGE>
Patent GB-2304909-A (GB)
Title: Optoelectronic current measuring device
Inventor: THOMAS MARTIN VINCENT
IPC: G01R19/00
Filed: 1995-09-07
Abstract: A device for the accurate generation and measurement of electrical currents in the femtoampere to nanoampere range, wherein the current is optically generated in either polarity by selectively illuminating two small-area photodiodes, wired in mutually opposing orientations. The beams reaching the two small-area detection photodiodes are generated by light-emitting diodes (LEDs), the control of which is linearised and stabilised by feedback loops incorporating secondary photodiodes. The current passed by the small-area photodiodes may be varied by changing either the voltage applied to the LED drive circuit, or the optical transfer efficiency from the LEDs to the detection photodiodes. In measurement of ionic currents across a cell membrane in a sample S, reference voltage V1 is applied to the sample by means of a negative feedback amplifier. Since the current is small, problems of noise from a resistive feedback or the need to reset a capacitive feedback are avoided by the use of the optical feedback.
Patent GB-2293840-A (GB)
Title: Drill bit having improved cutting structure with varying diamond density
Inventor: KEITH CARL W
IPC: E21B10/54
Filed: 1995-09-26
Abstract: A fixed cutter drill bit (10) includes a cutting structure having radially-spaced sets (50) of cutter elements (40). Each cutter (40) in a set (50) has a cutting profile that, in rotated profile, partially overlaps the cutting profiles of each of the other cutters that are in the same set so as to create a region (60) of maximum diamond density. The region (60) of maximum diamond density in a set (50) is defined such that the centrelines (41) of the cutting profiles of the elements (40) in the set (50) pass through the region (60) of maximum diamond density. The cutting profiles of the spaced sets of cutters also may overlap to create border regions (70) of multiple diamond density. The diamond density of border regions is less than or equal to the density in the region of maximum diamond density. Providing such regions of varying diamond density along the bit face tends to increase the bit's ability to resist vibration and provides an aggressive cutting structure, even after significant wear has occurred. <IMAGE>

Title: Thermal imaging system with controlled mean scene reference temperature source
Inventor: ASHLEY TIMOTHY
IPC: H04N5/365
Filed: 1995-10-02
Abstract: A thermal imaging system which is ac coupled and operates by scanning recreates a thermal image by superimposing measured variations in infrared emission from a scene 22 on to a reference level supplied by a light emitting diode 28 . The diode 28 is both a positive and negative luminescent emitter; emitted flux is current controlled to be equivalent to black body radiation at a range of temperatures which may be colder or hotter than ambient. A signal generated when the system switches between scene and diode observation is a measure of the difference between the mean scene temperature and the diode effective temperature. In response to this signal, control means adjust the bias current through the diode 28 in order to reduce the temperature difference. The reference temperature converges towards the mean scene temperature as this process is repeated. Absolute temperature is thus restored and some image defects removed.

Title: IC engine idling control
Inventor: KURIHARA MASARU
IPC: F02D31/00
Filed: 1995-10-17
Abstract: In an ic engine having an idling valve located in a bypass passage, the amount of fuel to be injected by an injector and the opening degree of the idling speed control valve are both calculated from a target physical amount which takes account of a balance between the engine torque and the engine friction. The target physical amount may be the intake air amount per intake stroke and is determined from a look up table that is corrected according to the detected engine speed. The correction also takes account of the integrated engine idling speed error and/or the a feedforward speed displacement dependent upon engine operating conditions eg a shift of the gear lever. The aim is to keep the engine torque and engine friction in equilibrium when the engine load changes. The response time of the system to changes in engine load is reduced by simultaneously controlling injection quantity and idle valve opening rather than making one dependent upon the effect of change to the other. <IMAGE>
