Patent GB-2198716-A (GB)
Title: A closure assembly for a container
Inventor: POORE ALBERT CYRIL GLANVILLE
IPC: B65D43/16
Filed: 1987-10-20
Abstract: The invention relates to a closure assembly for a container. The closure assembly comprises a first cap portion (11) hingedly connected to a second cap portion (12) adapted to be positioned over the mouth of an associated container and including an aperture to permit dispensing from the container. The first cap portion is arranged so that in one position it overlies the aperture to close the container, and in another position is lifted clear of the aperture to open the container. The cap portions together include means so that they can be snapped together and their separation from a closed to an open position requires the exertion of a positive force by the user and the first cap portion includes at its periphery opposite its hinged connection with the second cap portion a lip (22) which co-operates with an inwardly displaceable section (42) of the second cap portion. The inwardly displaceable section includes at its upper edge face adjacent the lip a portion which is associated with an outermost lower edge of the lip when the two cap portions are in a closed position and raised above that lower lip edge so that on inward displacement of the said section the raised portion first offers resistance to displacement in its engagement with the lip edge and then, as displacement pressure is increased, forces the lip upwards. In that manner the snap action of the two cap portions can be overcome and the closure opened.

Patent GB-2221364-A (GB)
Title: Laser detection countermeasure
Inventor: COLEMAN CLIVE IAN
IPC: G01S7/495
Filed: 1988-07-27
Abstract: A defensive device for use on a potential target, against an enemy employing a laser rangefinder. The rangefinding pulse is received and focussed (5) onto the end face of an optical fibre bundle (1). The fibre bundle is perhaps 20 metres long and has a reflective coating on the far end (7) which returns the pulse to the same spot on the input face to which it was originally focussed. The light pulse is thus directed by the same lens system (5) back along the direction from which it arrived but with a significant delay over a direct target reflection due to the length of the fibre bundle and the refractive index of the fibres. The focussing system serves both to accumulate a large amount of light and to provide automatic source direction finding. In a second embodiment, the far end (7) of the bundle is non-reflective and the bundle is bent back such that the pulse passes out therefrom for direction, via a second lens, back to the enemy. <IMAGE>

Title: Adaptive phase lock loop
Inventor: CHENG KING Y
IPC: H04L27/38
Filed: 1992-05-01
Abstract: An adaptive phase lock loop for jitter tracking. A filter in the adaptive PLL has coefficients that are automatically adjusted to minimize the error signal. The first block of the adaptive PLL is a phase shifter (13) that is used to eliminate the frequency offset and phase offset in the input signal (10). The output of the phase shifter (13) is received by a slicer (14) that makes an estimate of what the corrected signal should be. Then the difference between the input and output of the slicer (14) is multiplied (17) by the output of the slicer (14). The imaginary part (18) of the result is used as an estimate of the phase error. After passing through as an amplitude limiter (19) the signal is provided to a finite impulse response (FIR) filter (20) having adaptive coefficients. The FIR coefficients are adjusted to minimize the mean squared phase error using a gradient method. These coefficients are updated each baud. A second order loop is added to track any frequency offset present in the line signal. The signal is fed through a sin/cos table (27) back to the phase shifter (13). <IMAGE>
