Title: Optical pulse retiming and reshaping circuit
Inventor: EPWORTH RICHARD EDWARD
IPC: H04B10/2507
Filed: 1992-12-23
Abstract: An optical pulse retiming and reshaping circuit for soliton transmission in a transmission system (11) with distributed amplifiers transmits the pulses through an optical modulator (10), and uses a slow photodiode (31) to determine the mean power transmitted (or intercepted) by the modulator for use in generating a control signal (33) for use in a phase-locked loop to regulate the phase of an oscillator (34) driving the modulator. This overcomes noise, inter-pulse interference and the Gordon-Haus limitation. <IMAGE>

Title: Subsea systems
Inventor: HALVORSEN TORE
IPC: E21B43/017
Filed: 1993-11-30
Abstract: A subsea system comprises a central template 10 that is piled into the seabed and carries wing modules 22 that are connected to the template by hinges 23.

Title: Distance measuring arrangement
Inventor: JUBB LYNDON WAYNE
IPC: G01F23/284
Filed: 1993-12-10
Abstract: A radar distance measuring arrangement includes means for modulating a transmitted microwave signal with a first pseudo-random noise code (generated by shift register 4) at 15 and an IF signal at 13. The returns are modulated with a second pseudo-random noise code (generated by shift register 6) at 18 which is identical in pattern to the first code but is clocked at a different chipping frequency. When the second code comes into alignment with the returned first code a maximum occurs in the amplitude of the IF signal output by mixer 19; processor 25 compares the time of occurrence of this with the time of occurrence of a reference peak signal to give a time offset representative of the distance travel led by the transmitted signal. The reference peak signal by comparing 8, 9, 10 the second code with the transmitted first code. The time measurement by processor 25 can be in increments of 1 msec to give a measurement of time of flight accurate to 1 nsec; further refinement is possible by analysing the shape of the If signal maximum (Fig 5). The arrangement is particularly useful for monitoring the levels of liquids in a tank. <IMAGE>

Patent GB-2282128-A (GB)
Title: Tape dispenser
Inventor: YOKOUCHI NOBUO
IPC: B65H35/00
Filed: 1994-04-11
Abstract: A tape dispenser provided with a dispenser body having a tape retainer and a tape cutting blade and formed to such sizes that can be held by hand. The dispenser body is provided at its front portion with a member capable of pressing tape against an object on which the tape is to be pasted, and the blade is positioned ahead of the tape pressing member when the blade is in a free state. At least one of the tape pressing member and blade has escape displacement characteristics relative to the other which are displayed when a force is applied to the tape pressing member (namely, such displacement characteristics that permit the blade and tape pressing member to be displaced relatively to each other so that an angle between the dispenser body holding direction and the direction connecting a tape pressing point of the tape pressing member and the blade together decreases during a tape pressing and pasting operation). This enables the self-adhesion of a cut tape prior to the pasting of the tape on paper to be prevented reliably, and also the picking of the tape so as to draw out the same to be rendered unnecessary. Thus, the soiling of an adhesive surface of the tape and the occurrence of imperfect adhesion of the tape due to the dirt from the fingers can be prevented reliably. Moreover, the tape can be pasted over a predetermined length on paper without being wrinkled as it is drawn out with substantially no possibility of being cut erroneously and damaged. In addition, the tape can be cut easily without always varying the dispenser body holding angle greatly. <IMAGE>

IPC: G06F9/48
Filed: 1994-12-21
Abstract: A peripheral device includes an interrupt control unit (3), an interrupt request level holding unit (4), and an interrupt vector holding unit (5). The interrupt request level holding means and the interrupt vector holding means are loaded and updated by commands sent from an external device, eg. a sub-processor. When an interrupt is to be issued, the interrupt control unit reads the interrupt request level from the holding means and issues the interrupt to the processor. The interrupt control means also transfers the interrupt vector from the holding means to the processor. <IMAGE>
