Abstract: 952,508. Air cushion vehicles. VICKERSARMSTRONGS Ltd. July 6, 1962 [July 28, 1961], No. 27532/61. Heading B7K. A vehicle adapted to ride on an air cushion, air escaping laterally from the underside of the vehicle in use thereof, is provided along at least one side thereof with means for deflecting particles and the like rising from the surface over which the vehicle travels, each such deflecting means being concave on its underside, the concave underside serving for deflecting rising particles and the like downwardly and each deflecting means being shaped and disposed to permit, during forward motion of the vehicle on its air cushion, air flow over its surfaces in such a way that the occurrence of a negative pressure on the underside of the deflecting means is avoided. The vehicle 1 rides on an air cushion 2 contained by an air curtain 4 issuing from duct 3. A curved deflector 6 is attached to the vehicle so as to form a gap 8. In operation air from the curtain and spray are deflected downwardly by the deflector 6 and that passing through the gap 8 is deflected by a further deflector 10. It is stated that airflow over both faces of deflector 6 prevents the creation of a low-pressure area beneath the concave face with a resulting increase in operating efficiency. Additional cambered deflectors may be provided along the lateral sides of the vehicle at an incidence to the longitudinal axis to provide aerodynamic lift and arranged in overlapping relationship to restrict the upward movement of spray through the gaps between the deflectors.

Title: Improvements in or relating to buckles
IPC: A41F11/04
Filed: 1933-10-09
Abstract: 419,330. Buckles &c. PARVA PRODUCTS CO., Wilmington, Delaware, U.S.A.-(Assignees of White, P. W., and Heinze, P.) Oct. 9, 1933, No. 27768. Convention date, July 3. [Class 43.] A slide buckle comprises a pair of slidably engaged parallel frames, with side-bars and cross-bars forming slots to receive a strap, with means on one frame engaging the other to force the opposed faces of the frames closer together when they are moved along the strap relatively to one another, so as to clamp the strap between the opposed faces of co-operating cross-bars of the frames. Fig. 15 is a longitudinal section through a buckle for adjustably attaching a strap to an article of dress, comprising a lower frame 31, 32 attached, for example by sewing, to the dress and an upper frame 24, 26, 25 sliding on the lower, the strap being threaded through the two frames as shown dotted. The side-bars of the lower frame 31, 32 have parts 39 of tapering channel form, and projections 40 on the side-bars of the upper frame engage inside the front faces of these channel parts so that any upward tension on the strap, causing upward movement of the upper frame relative to the lower, produces a wedging action forcing the two frames closer together to grip the strap between the bars 31, 25, as shown; the projections 40 may be formed by the ends of the bar 25, this bar being made of U-section. In a modification, the channel parts 39 may be of parallel form, and the projections 40 are tapered instead. Figs. 10, 11 show this modification applied to a buckle adapted to be buttoned, instead of permanently attached, to a garment ; the lower bar 32 of the lower frame is in this case formed with a loop 34 to engage the stem of the button. The bar 25 of the upper frame and 31 of the lower frame may be cut away as shown at 46, 47 to give greater space for insertion of the button ; the sides of the loop 34 are formed with projecting parts 36 which guide the button over the bar 25 of the upper frame to prevent detachment if the button tends to move upwards when the strap is slack. The bar 25 is preferably provided with a lip 41 projecting upwardly and inwardly to clamp the middle part of the strap against the lower frame bar 31, the edges of the strap, which may be thicker, being left free. The lip 41 and cutaway part 46 may be produced by giving the bar 25 a partly curved form, with a straight centre portion nearer to the bar 26 than the end portions. In a further modification, with the channel parts 39 of parallel form, the projections 40 are formed to guide the upper frame parallel to the lower and the bar 31 is inclined upwardly and forwardly in cross-section so that upward movement of the upper frame on the lower produces a relative movement of the two clamping faces towards each other.
