Graseby

Graseby was a British engineering company.

History

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.

On 16 March 1998 Smith Industries sold Graseby Andersen and Graseby Product Monitoring to Thermo Electron. Graseby Product Monitoring included Goring Kerr,[2] 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.

gollark: Anyway, single-precision floats can hold 2^32 values. Assuming you want to map each float to another float, you therefore only need 2^36 bytes of memory to store the lookup table.
gollark: I agree.
gollark: * of, even
gollark: We actually have enough RAM now that you could plausibly have a lookup table for all 32-bit floats.
gollark: This is because floats have a finite size, so there are finitely many possible floats.
