Title: Gaseous suspension particle size measurement
Inventor: PYE JOHN ALBERT
IPC: G01N21/53
Filed: 1991-03-19
Abstract: A radiation source 5 sequentially projects a beam of radiation at different wavelengths into a test space 7 containing the gaseous suspension to be measured. A sensor 6 arranged at an angle to the intersection of the beam with the test space 7 responds to radiation scattered by the particles. The particle size is determined from the respective amounts of radiation detected by the detector at the different wavelengths. The test space may be defined by the interior of a transparent tube through which the suspension is passed, the source and sensor being disposed on the exterior. An auxiliary sensor may compensate for build up of particles on the tube walls. Alternatively the beam may be directed into the exhaust plume of a motor vehicle, no physical containment being employed. <IMAGE>

Title: Fuel injection system for an internal combustion engine
Inventor: AUGUSTIN ULRICH
IPC: F02M59/46
Filed: 1995-03-31
Abstract: In a fuel injection system having a high-pressure pump 2 feeding a common supply rail 3 which acts as a pressure reservoir and which is provided for magnetic-valve controlled injection nozzles, there is provided an electromagnetically actuable control valve 4 which also acts as a non-return valve in the high-pressure conducts connecting the high-pressure pump 2 to the supply rail 3. By means of this control valve, the function of the non-return valve 4 can be suspended during the relief or return stroke of the pump plunged 8 and rapid pressure relief in the pressure rail 3 can be achieved to match rapid changes in load on the internal combustion engine. Thus the actual delivery stroke is represented by the portion of the return stroke remaining after the control valve is allowed to close. <IMAGE>

Title: Method and apparatus for measuring antenna performance
Inventor: PIKE SIMON EVERETT
IPC: G01R29/10
Filed: 1995-11-04
Abstract: Magnitudes of reflection of individual discontinuities (18) in an antenna system (12) are assessed by the apparatus of FIG. 1. A carrier signal is modulated with a symbol sequence, with a resultant modulated signal injected into the antenna system to generate a reflected signal (56) from a discontinuity. At the same time, the symbol sequence is delayed (52). A test signal (60), having a power spectrum, is then produced by modulating the reflected signal (56) with the delayed symbol sequence thereby producing a test signal having a power spectrum. Filtering of the test signal (60) through a filter (32) produces a filtered signal (33) in which a proportion of the power spectrum is passed dependent on an amount of cancellation of modulation in the test signal (60) arising from modulating the reflected signal (56) with the delayed symbol sequence. A power level for the filtered signal is then determined to assess the magnitude of the reflection.

Title: Sensing system
Inventor: EVANS JONATHAN PAUL
IPC: G01G3/142
Filed: 1997-06-02
Abstract: A system for sensing the value of a physical property for example a weighing system where a plurality of load cells are employed to sense the magnitude of a load placed on a weighing platform. The outputs of the load cells are cyclically selected and applied to a first analogue to digital (A/D) converter 7 and a second A/D converter 3 capable of faster operation than said first A/D converter. The first A/D converter 7 produces a signal representative of the average of the physical property and said second A/D converter 3 produces a signal representative of the distribution of sensor output signal amplitudes amongst the sensors. The signal from the second A/D converter 3 is used to process the signal from the first to provide a correction that improves the accuracy of the high resolution signal. The need for an expensive high resolution high speed A/D converter is avoided.
Patent GB-977158-A (GB)
IPC: G01N21/89
Abstract: 977,158. Counting apparatus. JONES & LAUGHLIN STEEL CORPORATION. July 11,1962 [Nov. 12,1961], No. 26730/62. Heading G4D. Visible defects on the surface of a moving material are scanned electronically and counted, the count giving an indication of the surface condition. Each time a defect is detected a pulse is generated, the oppositely phased pulse when the scan passes from a defect to sound material being deleted. By arranging that the vertical scanning velocity is twice the speed of the material, as measured by a tachometer, it is ensured that each defect shall be detected once only. As an alternative, speed compensation may be provided by gating pulses of frequency related to the speed of the material. After predetermined lengths of material have been examined the resultant counts are printed and the counter zeroised.

Title: Controlling the signals of an ERMES pager
Inventor: TSENG SHYI-JING
IPC: H04W88/02
Filed: 1998-04-07
Abstract: BY an RF-signal controlling method applied for controlling the operation of a pager in an ERMES system, the pagers can establish a synchronization link with the base stations during the shortest time interval, and lock on the home channel rapidly to receive messages by channel scanning. Furthermore, the pagers can finish receiving messages while in a mode of channel switching, in roaming states or in the border areas with weak signals. In the mode of channel switching, the same data is sent in different channels, but relatively time-displaced. Fig. 3A shows the method. In step e, the pager compares the received "frequency subset indicator" FSI and "operator identity" OPID with its own corresponding information. A received "border area indicator" BAI equal to 1 causes the mode of channel switching to be used, as in the roaming process.

Patent GB-2342385-A (GB)
Title: Power actuator for vehicle lock
Inventor: SPURR NIGEL VICTOR
IPC: E05B65/12
Filed: 1998-10-10
Abstract: A motor driven rotatable annulus 20 carries an index member 40, a drive pin 52 of which acts via a link 62 on the lock and is acted on when the lock is manually operated. One surface of the annulus has control slots 36 receiving the pin 52 and the other has notches 28 with intervening lands 30. When the lock is operated manually, the force applied to the pin 52 causes it to ride between the slots 36 to index the manual actions. A pin 46 of member 40 slides and pivots in a slot 48 to allow this movement. When the annulus is rotated by the motor a land 30 engages projection 50 on the member 40 to prevent the sliding of pin 46. The pin 52 is therefore retained in a single slot 36 to be driven by the annulus.

Title: Apparatus and method for demonstrating and confirming the status of digital certificates and other data
Inventor: KOCHER PAUL CARL
IPC: H04L9/32
Filed: 1997-05-13
Abstract: Methods and apparatuses are disclosed for providing cryptographic assurance to whether a particular data item is on a list. Typically the data item would he a digital certificate and the list would specify revoked certificates. The list of data items is typically converted into a set of ranges in which no data items exist, then the ranges are used as leaf nodes to construct a hash tree using a cryptographic hash function. The root node of the hash tree is digitally signed. A cryptographic confirmation whether a particular item is on the list consists of the range including the item in question, the hash tree nodes necessary to reconstruct the root from the range, and the digital signature on the root node. Verification of the confirmation involves testing the digital signature on the root node and checking that the root node can be constructed from a leaf node whose range includes the item in question.
