Title: Nuclear magnetic resonance method and apparatus
Inventor: BAILES DAVID ROBERT
IPC: G01R33/48
Filed: 1984-06-01
Abstract: A NMR imaging method and apparatus effective to cause spins of a chosen nucleus within a body to rotate through an angle of 180 DEG wherein degradation of the image due to non-uniformity of the r.f. coil is reduced. The method includes applying an even number of r.f. magnetic field pulses (B2, B4) at the Larmor frequency for a chosen nucleus in the body and each intended to rotate the spins of these nuclei through 180%, half of the number of pulses having a phase difference of 180 DEG  with respect to the other half of the number of pulses. NMR signals from the body are measured after each pulse, and the signals are averaged. The method is applicable to spin-echo sequences, as shown, to inversion recovery sequences, and also to multi-slice sequences where the pulses are accompanied by a selection gradient. More than one pair of pulses B2, B4 may be used. <IMAGE>

Abstract: A liner cup 2 can be removed from a golf hole 1 by a tool with a shaft 6 and wedge-shaped member 9 pivoted on arms 8 extending radially from the shaft so that members 9 pivot upwards and inwards as the shaft is positioned in the cup (by placing nose 6a into the conventional bottom recess) and pivot outwards to frictionally grip by their curved outer edges 9a the cup surface as the shaft is pulled up, thereby removing the cup 2 from the ground. in wet weather the tool includes a saucer 11 which is shiftable, via a sleeve 12, toward or away from the members 9. During insertion of the shaft 6 into the hole, handles 7a and 14a are gripped thereby withdrawing, through a link 13, the sleeve 12 and saucer 11 to allow members 9 to pivot upwards. Thereafter handles 7 and 14b are gripped instead to shift sleeve 12 and saucer 11 to forcibly abut members 9, thereby maintaining their outward pivoting motion and frictional grip of the liner for its removal. <IMAGE>
Patent GB-2283882-A (GB)
Title: Secure communication system
Inventor: SOSIN BOLESLAW MARIAN
IPC: H04B1/713
Filed: 1984-11-23
Abstract: A communication system uses a frequency hopping technique in which the hopping rate is not less than the data bit rate of a transmitted message. The frequency transmitted at any instant is determined by the current output of one of a plurality of pseudo-random sequence generators 5, 6, the particular sequence used being selected in dependence on the current value of the data bit. (For example, if the current bit is "1" the output of generator 5 determines the frequency transmitted, whereas if the bit is "0" generator 6 determines the frequency). A cooperating receiver generates the same codes and frequencies in synchronism with the transmitter, and by comparing received frequency values with locally generated frequency values, the original message is reconstitued. The system is very resistant to jamming. <IMAGE>

Inventor: BAKER ROBERT
IPC: H01S3/067
Filed: 1988-05-27
Abstract: A fibre laser in whose laser cavity is arranged a resonant coupler (15) which is laser wavelength selective. The laser cavity is defined between a broadband reflector (17) at one end of a laser fibre (10) and a broadband reflector (16) at one end of an optical fibre (14). An optical pump signal is applied to the other end (12) of the laser fibre (10) and a laser output is obtained from the other end (18) of the optical fibre (14). The fibre laser is thus effectively pumped internally of the cavity. Only simple mirrors are required for the reflectors (16, 17) instead of the dichroic mirrors of conventional fibre lasers which involve alignment problems. The arrangement acts as an optical amplifier for an input signal, namely the pump signal referred to above. <IMAGE>
