Inventor: MANDER MICHAEL GEORGE
IPC: E05B17/00
Filed: 1989-02-01
Abstract: A door handle spindle is provided along its length with a weakened portion in the form of a peripheral groove (21). The spindle can be of one piece and can have two such grooves (21) of semi-circular cross-section and axially spaced apart, or it can be a split spindle formed of two interconnected parts which can relatively rotate through a pin and groove connection, but which cannot move relatively axially. In this case the weakened portion (21) would be either in the spindle part (18) which has a spigot (18a) engaging in the other spindle part (17) or would be in the spindle part in which a spigot of the other part is received. When used to mount door handles at a lock fitted to a door, the spindle has the or each of its weakened portions disposed outside of the lock. The weakened portion is so arranged that the spindle shears at said portion at a torque value which is less than that which could cause damage to the lock with which the spindle is used. <IMAGE>

Patent GB-2220269-A (GB)
Title: Magnetic resonance imaging
Inventor: SEPPONEN RAIMO ERIK
IPC: G01R33/44
Filed: 1989-05-26
Abstract: In an imaging system in which a nuclear spin system is indirectly excited by direct excitation of an electron spin system coupled to the nuclei in the presence of a first polarising magnetic field, the NMR signal is detected in the presence of a second polarising field different from the first. Thus a second, higher intensity, field may lead to a better signal to noise ratio and the possibility of recording chemical shifts. During ESR excitation, other spin systems may be saturated to narrow the ESR line. Such saturation, and the ESR irradiation, may be stopped during detection of the NMR signal.
