Title: Load carrying cushioning device with improved barrier material for control of diffusion pumping
Inventor: RUDY MARION FRANKLIN
IPC: F16F9/04
Filed: 1990-01-11
Granted: 1996-10-15
Abstract: A product in the form of a cushioning device made from thermoplastic film containing crystalline material inflated to a relatively high pressure and sealed at the time of manufacture. The product maintains the internal inflatant pressure for long periods of time by employing a form of the diffusion pumping phenomenon of self-inflation in which the mobile gas is the gas components of air other than nitrogen.          Improved and novel cushioning devices use new materials, for the film of the enclosure envelope which can selectively control the rate of diffusion pumping, thereby permitting a wider latitude flexibility and greater accuracy in the design of such new cushioning device, thus improving the performance and reducing cost of such devices while eliminating some of the disadvantages of the earlier products. It is possible to permanently inflate certain types of new devices using readily available gases such as nitrogen, or air in which case nitrogen forms the captive gas.

Filed: 1991-01-15
Granted: 1996-04-23
Abstract: Alkyl-isothiocyanic esters having the formula R-N=C=S can be produced by reacting N-alkyl dithiocarbaminates with hydrogen peroxide in aqueous phase at 95 to 130°C.  According to the present invention the aqueous N-alkyl dithiocarbaminate solution is reacted with a 20 to 40% by weight aqueous hydrogen peroxide solution in a volume ratio of 1:0.8 to 1 while maintaining a pH value of 1.5 to 4.5. The solutions are preferably sprayed into a reactor while alkylisothiocyanate formed is distilled off in the form of a vapour and the aqueous phase containing the by-products accumulates in the reactor.  By means of the process according to the present invention the space-time yield could be increased significantly while, as compared with the conventional process that is carried out at pH 5 to 9, the amount of sulphur formed is substantially reduced and the shut off times for cleaning the reactor can be minimized.
