Graseby
From Wikipedia, the free encyclopedia
Graseby was a British engineering company.
As Graseby Instruments it made and refurbished naval sonar equipment. The company (00385807) was established on 25 February 1944. It was initially situated in Tolworth in south-west London.[1]
On 1 January 1982 it merged with Pye Dynamics forming Graseby Dynamics and moved its operations to the latter's site in Bushey, Hertfordshire. Graseby Dynamics' business activities were:
- Marine - the ex-Instruments services,
- Medical - principally Cot Death Monitors and Continuous Syringe Drivers,
- Ordnance - including test and post-design services,
- RF products - specialist services and the manufacture of Personal Locator Beacons (PLBs),
- Ionics/Security/Analytical providing vapour detectors based up Ion Mobility Spectrometry - the three identities addressing the Military, Civil and Space markets respectively.
Later Graseby Dynamics became part of Cambridge Electronic Industries plc. As part of a rationalisation process Cambridge Electronic Industries later changed it name to Graseby plc in January 1992 - a process it extended to many of its remaining subsidiaries, e.g. Newmarket Semiconductors became Graseby Semiconductors
In April 1988 Graseby Ionics won the Queen's Award for Technological Achievement for CAM, a hand-held chemical agent monitor.
In May 1992 Graseby plc bought Intertest.
On 7 August 1997 it was bought for £136m (US$216.7m) by Smiths Industries.[2]
On 16 March 1998 Smith Industries sold Graseby Andersen and Graseby Product Monitoring to Thermo Electron. Graseby Product Monitoring included Goring Kerr,[3] Best and Allen Coding was absorbed by Thermo Sentron for US$43m. Thermo Sentron also owned competing brands such as Ramsey and Icore. Thermo Instrument Systems acquired Graseby Andersen. The aggregate price was US$73 million. Combined revenues of these companies were US$78 million.
