Title: A vent valve for a vehicle fuel tank
Inventor: PARDY RONALD PETER
IPC: B60K15/035
Filed: 1992-08-08
Abstract: A vent valve for a vehicle fuel tank is provided with a fuel-impervious cup 11 sealed around a conventional float valve which is mounted in the upper wall 2 in the vehicle fuel tank. The cup 11 has an inlet weir port 14 and a drain port 13 which is sealed by a non-return valve 12. Fuel may only enter the cup through the inlet port 14 when the fuel within the tank reaches the level of the inlet port. By positioning the port 14 close to the upper wall 2 of the fuel tank more of the potential volume of the fuel tank may be used for fuel storage. Alternative forms of one-way, non-return valves, eg a float valve (20, Figure 3), may be used to seal the drain port 13. The cup 11 may be formed integrally with the upper wall 2 or as part of the grommet 6 which is sealed into the wall 2 to provide a coupling to a vent pipe 7. The float valve is mounted within a cage 10. <IMAGE>

Title: Method of and device for determining the degree of fouling of a printing unit of a printing machine
Inventor: MILTNER KARL-HERMANN
IPC: G01N21/59
Filed: 1993-05-26
Abstract: A device for determining the degree of fouling of a printing unit of a printing machine comprises a light beam 4 directed through a transparent pipe 1, down which the waste washing solution flows, towards an optical sensor 5 which compares the intensity of the transmitted light with that when clean solution is flowing. A filter 3 of the complementary colour to the ink used may be inserted in the white light beam. If the intensity of the transmitted light is low then the density of ink is high and further washing runs may be required. Alternative methods of measurement disclosed include chemical tests, density and electrical conductivity. <IMAGE>

Title: Motion detecting system
Inventor: APPLEBY DAVID
IPC: G08B29/18
Filed: 1993-06-12
Abstract: In a system for detecting motion within a field of view, such as for intruder detection, in which a first condition is sensed to derive a value relating to motion, and an output signal is produced if the value has a predetermined relation to a threshold value, the threshold value is dependent upon a second value derived by sensing a second condition. Thus the signal from a PIR detector 2 may be compared with a threshold dependent upon a signal from a thermistor sensing the temperature of a common head 1; or an ultrasonic Doppler signal from a sensor 6 may be thresholded against a value determined by the intensity of the unshifted frequency signal e.g. at times between the emission of ultrasonic pulses from emitter 5 at which directly emitted sound is not detected. The system shown comprises both PIR and Doppler systems in the same head 1, and the output of one system is effectively subject to a threshold determined by the other system to determine whether an alarm or other output should be produced. <IMAGE>

Title: FSK receivers
Inventor: MINAMI YOICHIRO
IPC: H04L7/00
Filed: 1993-09-16
Abstract: In an FSK receiver of double superheterodyne type comprising a PLL local oscillator (10) and a demodulating section (12), a control signal producing circuit (14) produces a control signal when the demodulated signal has a mean value indicative of a deviation from a phase lock in the phase-locked loop. A synchronizing circuit (16) establishes bit and frame synchronization on the basis of a binary digital signal obtained by deciding the demodulated signal to produce a synchronization detection signal. Connected to the PLL local oscillator, the control signal producing circuit, and the synchronizing circuit, an intermittent driving circuit (18) makes the PLL local oscillator intermittently operate on the basis of the control signal and the synchronization detection signal. The PLL intermittent driving circuit makes the PLL local oscillator stop or start its PLL operation in dependence upon the control signal being absent or present. <IMAGE>

Title: Apparatus and method for varying the coupling of a radio frequency signal
Inventor: SCHWENT DALE GERALD
IPC: H04B1/04
Filed: 1994-04-05
Abstract: An apparatus and method for varying coupling of a radio frequency (RF) signal (408). This is advantageously used for increasing the dynamic range of a powder detector (406) in an automatic power level control loop (403) of a transmission unit (404), while maintaining transmission unit efficiency at higher power levels. This is accomplished by selecting between a first operating mode of the RF coupler (405) having strong coupling, responsive to a first predetermined power level, such that the RF coupler (405) produces a first coupled RF signal (509) responsive to the RF signal (408) and a second operating mode of the RF coupler (405) having a weak coupling, responsive to a second predetermined power level, such that the RF coupler (405) produces a second coupled RF signal (510) responsive to the RF signal (408). <IMAGE>

Title: A shock proof buckle mechanism
Inventor: DOWNIE ANDREW JOHN
IPC: A44B11/25
Filed: 1995-05-10
Abstract: A buckle mechanism, for vehicle safety restraint systems, comprises a push button 14 having abutments 29 which engages with abutments 22 on rocker 6 so as to prevent disengagement of a lockbar 9 with belt tongue 26 during, for example, a crash situation. The rocker 6 is pivotly mounted, via pivot bar 7, and carries the lockbar 9 which is biased into engagement with the tongue 26 by a three pronged leaf spring 10. When inertia forces, eg at an end of a pretensioning operation, cause the button 14 to continue moving an overlock plate 11 moves with it and hook 25 on the overlock plate 11 co-operates with bar 28, thereby stopping the spurious release of the mechanism. A ramp surface 30 on button 14 has three areas of different gradients, preferably 50, 20, and 50 degs respectively, which engage at different button displacements so as to disengage the lockbar 9. At one stage during disengement one of the gradients produces lost motion between the lockbar 9 and the rocker 6 which results in spring 10 being lifted off the lockbar 9. <IMAGE>
