Abstract

586,870. Tents. C. B. PROJECTIONS (ENGINEERING), Ltd., and BELL, C. S. Oct. 1, 1942, No. 13809. [Class 20 (i)] [Also in Groups XX and XXI] A tent-like chamber has a wall 11 of segmental spherical shape, built up of overlapping segments of flexible material such as rubberized fabric, there being provided a low-pressure blower supplying air through an inlet 19 to inflate the chamber, a relief-valve (not shown) arranged to open when the pressure in the chamber is sufficient to inflate it fully, and an airlock for access to the chamber. The airlock comprises a structure covered by an extension 18 of the wall 11 and having inner and outer doors 15, 13. The interior of the wall, which is coated with aluminium powder or the like, serves as a kinematograph screen, for use with projecting-apparatus 26 which serves, in conjunction with an aiming device for training marksmen (see Group XXI).
