Title: Removable electric lighting fitting
Inventor: WILTSHIRE RAYMOND
IPC: F21V21/04
Filed: 1988-11-23
Abstract: A downlighter light fitting comprises an outer part which normally remains in an installed position (e.g. in a ceiling) and an inner assembly or "shuttle" which is readily removable from, and replaceable in, said outer part. The "shuttle" comprises a lampholder retained by bent-over end portions of limbs (23) of springs of the outer part.

Title: Improvements to gas selector valves
Inventor: WILLIAMSON DAVID THEODORE NELS
IPC: F16K11/074
Filed: 1989-06-27
Abstract: In gas analysis systems it is frequently necessary to draw a gas sample from one of an array of pipes each of which conveys gas from a different remote position to the central monitoring point. In order that the gas sample may be fresh the pipes not in use must be continuously purged while the gas sample is being withdrawn and analysed from the selected pipe. The valve in this invention consists of a stator 1 to which the sampling pipes 2 are brought and arranged in a circular ring. The outlets are coupled to a rotor 5 so shaped and positioned that only one pipe is connected through to the analyser whilst all the others are connected to the vacuum purging pump. By rotating and positioning the rotor any pipe may be selected either in sequence or at random whilst all the others are automatically purged. <IMAGE>
