Abstract: A vehicle transmission employs a pair of coaxial input shafts, one driven at fixed ratio and the other driven at an infinitely variable ratio through a hydrostatic transmission which relatively reverses direction of rotation. A single input-dual input planetary gear assembly couples the coaxial input shafts to an output shaft. The planetary gear assembly is made up of a reverse and low forward speed planetary gear set and a high forward speed planetary gear set connected together to provide a four element planetary gear assembly synchronously shiftable between low and high ranges and which provides torque multiplication throughout the speed range and produces the same direction of rotation of all four elements at substantially or at the same speed when operating at the maximum forward speed condition.

Abstract: A collapsible, self-supporting structure is disclosed wherein the structure is made up of a network of rod elements pivotally joined at their ends and forming scissors-like pairs in which rod element crossing points are pivotally joined. The network consists of a plurality of pairs of inner and outer apical points where groups of radiating rods are pivotally joined. The outer apical points lie on a surface of revolution such as a spherical section and each group of rods radiating from an inner apical point lie essentially in a common plane whereby to effect the self-supporting action. For any pair of apical points the group of rods defining the inner apical point radiate in their common plane and join rods of other groups at the surrounding outer apical points.

Abstract: In the making of vehicle bodies such as truck and trailer bodies, the roof sheets are secured to the roof bows by means of a hot melt adhesive. Premature cooling of the adhesive which otherwise does not allow sufficient time to position the roof sheet and then mate it with the roof bows properly after the adhesive is applied, is prevented by employing a heat-insulating layer of glass fiber scrim cloth on the roof bows and upon which the hot melt adhesive is applied. Temporary clamping pressure forces the hot melt adhesive through the pores of the scrim cloth and into contact with the roof bows whereupon it rapidly cools and sets. The presence of the scrim cloth provides a substantial increase in the otherwise unacceptably low bonding strength of the hot melt adhesive.

Abstract: Paint-laden air extracted from a paint-spraying booth is scrubbed by passing the paint-laden air together with a flow of water through at least one tube which extends downwards from the floor of the booth to a position spaced from the bottom of a water-container. A perforated baffle is located between the bottom of the water-container an an air velocity control opening associated with the tube, or one with each tube, the opening being of lesser cross-section than the tube and the perforations small as compared with the opening. A first stage separation of paint from air is effected by impingement against the baffle, a second stage by impingement of paint-laden air which passes through the perforations against water on the bottom of the water-container, and a third stage by passage of air through an annular curtain of water formed between the control opening and the surface of water in the water-container.
