Title: Providing an aperture in a wall
Inventor: HODGSON T D
IPC: G21C19/38
Filed: 1989-08-07
Abstract: A process for providing an aperture in a wall having a protective layer 4 (e.g. a wall of a container such as fuel cladding 2 of a nuclear fuel pin) includes the step of disrupting the protective layer (e.g. by scratching with a probe 5) at a selected location so as to facilitate dissolution of the wall at the location when contacted with a solvent thereby to produce an aperture in the wall. The fuel can then be removed from the fuel pin by means of a solvent through the formed aperture. <IMAGE>

Title: A high Q helical resonator
Inventor: EVERARD JEREMY KENNETH ARTHUR
IPC: H03H5/00
Filed: 1989-08-30
Abstract: A high Q helical resonator is described which is directly coupled and resonant for lengths of approximately  lambda /2. The helical resonator consists of a helical transmission line wound between two connectors with a portion of the coil at either end connected to ground where the connection to ground could also be via a capacitor. The equivalent circuit consists of a low-loss helical transmission line and two shunt inductances or capacitors at either end connected to ground. This resonator is extremely easy to fabricate and is used as a high Q filter and as the resonator in state of the art low noise oscillators. Varactor diodes may be used to time the resonant frequency. The helix, the shunt components and the enclosure may be made of superconducting components. <IMAGE>

Title: Linear motor with speed and/or position sensor
Inventor: KELLY HUGH-PETER GRANVILLE
IPC: H02P25/06
Filed: 1990-09-04
Abstract: A linear motor comprises a stator 1 and an armature 2 provided, respectively, with a set of spaced apart permanent magnets and a set of drive coils (not shown). The permanent magnets produce a radial magnetic field whose strength varies periodically along the length of the stator 1. The field strength is to derive speed and position signals by means of detectors constituted by field coils 4 and Hall Effect sensors 10. The periodic variation of the field strength is compensated for in the case of the field coils 4 by staggering their phases along the length of the armature and selectively combining their outputs; in the case of the Hall Effect sensors, the periodical variation is used to derive positional information.

Title: Method and apparatus for surface treatment
Inventor: YOSHIKAWA MASATO
IPC: B29C59/14
Filed: 1992-08-19
Abstract: An object (4) is subjected to a surface treatment by locating it in an atmospheric pressure plasma i.e. at 200 torr - 3 atm., while rolling or floating the object (4) in an insulating vessel (1) fed with a prescribed gas and provided on the outside thereof or on both the outside and inside thereof with electrodes (2a, 2b) which are used to form the atmospheric pressure plasma. Thus uniform surface treatment of any object in the form of lump or sphere or powder is obtained. For example, vulcanized rubber can be surface treated with an atmospheric pressure plasma in the presence of an oxygen-containing gas and halogen containing gases to improve its adhesion properties. Numerous different electrode configurations and different gas fillings for forming the atmospheric pressure glow discharge are disclosed. As shown, the object 4 may roll down an inclined tube 1, the tube itself may be reciprocated so that the object rolls back and forth, Fig. 11 (not shown). Alternatively, the object may float up and down in a vertical tube having a hinged flap at one end, Fig. 12 (not shown). The inner electrodes may also form supports along which the objects roll, Figs 32, 33 (not shown). The objects may also be located on a moving belt, Figs 13, 14 (not shown). <IMAGE>
