After testing the VT-158 in various existing sets such as the SCR-268, a team led by Captain John Marchetti incorporated the VT-158 in a new system designated as the SCR-602. [7] [8] The original SCR-602, known as SCR-602-T1 for “Type 1”, was almost an exact copy of the British LW radar. With the implementation of the VT-158, Marchetti's ...
The R-value is the building industry term [3] for thermal resistance "per unit area." [4] It is sometimes denoted RSI-value if the SI units are used. [5] An R-value can be given for a material (e.g., for polyethylene foam), or for an assembly of materials (e.g., a wall or a window). In the case of materials, it is often expressed in terms of R ...
The firm was rebranded W Edwards and Co in 1940, then Edwards High Vacuum International Ltd in 1950, and moved from London to Crawley in 1953. [2] [18] [3] [19] Edwards purchased Italian freeze-drying equipment manufacturer Alto Vuoto SpA in 1954, followed by the Shoreham factory of former subcontractor J H Holmes and Son Ltd in 1958.
Typical R-values are given for various materials and structures as approximations based on the average of available figures and are sorted by lowest value. R-value at 1 m gives R-values normalised to a 1 metre (3 ft 3 in) thickness and sorts by median value of the range.

In practice, the value is usually measured at 20% elongation in a tensile test. For sheet metals , the R {\displaystyle R} values are usually determined for three different directions of loading in-plane ( 0 ∘ , 45 ∘ , 90 ∘ {\displaystyle 0^{\circ },45^{\circ },90^{\circ }} to the rolling direction ) and the normal R-value is taken to be ...
