Abstract: A panel having particular utility in a chair or other apparatus for receiving an occupant in a seated position includes an envelope of resilient material having at least one small opening for receiving a substantially rigid and U-shaped envelope support frame. The envelope support frame is inserted into the envelope through the opening and positioned inside the envelope to tension the resilient material of the envelope in one or more tension zones. A rear support frame bar is then inserted into the opening and connected to the envelope support frame. The small opening may then be sewn closed, knitted, or heat sealed. The width of each tension zone when the envelope is in its relaxed state is different than the width of each immediately adjacent tension zone.

Abstract: A panel having particular utility in a chair or other apparatus for receiving an occupant in a seated position includes an envelope of resilient material having an opening with a fastener for closing the envelope. An envelope support frame is substantially rigid and formed in a closed loop. The envelope support frame is positioned inside the envelope to tension the resilient material of the envelope in one or more tension zones. A fastener is closed to envelop the envelope support frame with the resilient material. The width of each tension zone when the envelope is in a its relaxed state is different than the width of each immediately adjacent tension zone.

Abstract: The method first defines a population for Product Cash Revenue and a population for Product Lease Revenue and calculating the mean, median, and variance of the populations and determining therefrom the normality of each of the distributions. Next, the variances of each of the distributions are compared for equivalency by a Homogeneity of Variance test. If each of the distributions are not normal and the variances are not equal then the fair market value is not determinable. Otherwise, if each of the distributions are not normal and the variances are equal then the method further comprises determining if the medians of each of the distributions are equivalent by Mann-Whitney. If the medians of each of the distributions are not equivalent then the values of the leases are adjusted by the lowest constant in whole dollars until the means of each distribution are equivalent.

Abstract: The present invention describes an engine having an oil pan (100) with a pick-up tube (140) for moving oil from an oil reservoir (105) to an oil pump (130). An engine crankcase (110) is connected to a front cover (120) having a front half (122) and a back half (124). The oil pan (100) is connected to the crankcase (110) and the front cover (120). A pick-up tube (140) is disposed along the oil pan (100) and connects the oil reservoir (105) to an inlet path (128) formed by the front half (122). A nipple (150) connects to the pick-up tube (140) to the front half by being inserted into an opening (129) of the inlet path (128). A gasket (160) is disposed adjacent to the nipple (150) and between the pick-up tube (140) and the front half (122). An alternate embodiment omits the nipple (150).

Abstract: An internal combustion engine includes a spaced apart surge tank, the surge tank being an integral component of a pressurized liquid engine cooling system. A first conduit fluidly couples the surge tank to a component of the pressurized liquid engine cooling system. The conduit has an internal fluid passageway defined therein. The conduit is heat responsive, an application of heat to the conduit acting to effect a contraction of the fluid passageway. Further, a method of controlling fluid flow in a conduit connecting the surge tank to a component of a pressurized liquid engine cooling system, comprises the steps of:forming the conduit of a heat responsive material;flowing a fluid through the conduit;running the engine to an elevated fluid temperature; andcontracting the conduit fluid passageway responsive to the heating of the conduit caused by the fluid flow therein.

Abstract: A stacking armchair having two symmetrical front frame members, each having a bottom rail portion, a front leg portions, and a seat side rail portion, a rear connecting member connecting together the rear ends of the side frame portion, a front brace across the front leg portions. All these are made from thin rod stock. The rear of each bottom rail portion has a turned-up generally vertical terminal portion, and the rear connecting member extends out beyond the seat side rail portions. Two rear leg members are made of rod stock greater in thickness, strength, and stiffness than the rod stock from which the front frame members are made. The rear leg members are butt-welded at their lower ends to the tops of the terminal portions and are also welded to the ends of the rear connecting member. A seat is secured to the side rail portions and to the rear connecting member, and a back is secured to upper portions of the rear leg members.

Abstract: A stacking armchair and a chair frame therefor. A horizontal frame member has an U-shaped, horizontal portion and a pair of downwardly and outwardly turned vertical front portions. The horizontal portion comprises a lateral rear portion and horizontal side portions that lie generally parallel to each other, but diverge somewhat from rear to front. Two frame juncture members are secured to the frame side portions adjacent the rear lateral portion. Each of a pair of rear legs with integral back-support portions is secured to a frame juncture member, so that they are spaced apart from each other farther than are the side rails. They provide nearly parallel back-support portions that diverge slightly from each other. To these, along mating sloping faces are secured arm and front leg members providing arms parallel to and outboard of said side rails and also providing the chair's vertical front legs. The front portions of the horizontal frame member are secured to upper portions of the front legs.

Abstract: A stacking armchair and a metal chair frame therefor. One frame member has an U-shaped, horizontal portion and a pair of vertical front legs. The horizontal portion comprises a lateral rear portion and horizontal side portions that lie generally parallel to each other, but diverge somewhat from rear to front. Each of two flanged frame juncture members has a horizontal top and a pair of vertical side flanges; the top has a pair of horizontal edges and each side has a pair of vertical edges. One horizontal edge and two vertical edges of each are welded to the frame side portions adjacent the rear lateral portion. Each of a pair of rear legs with integral back-support portions is welded to the other horizontal and vertical edges, so that they are spaced apart from each other farther than are the front legs. They provide nearly parallel back-support portions that diverge slightly from each other. To these, along mating sloping faces are welded arm members.

Abstract: A seat-back unit for a chair utilizes pre-flexed sheets of sinuous spring wire material connected to relatively rigid side support members which afford flexibility, but provide a frame for the unit. The two L-shaped side support members are held apart by a rigid cross stretcher member positioned in the seat portion, near the back. The seat-back unit is connected to a chair frame at only four points in a "cradling" arrangement, by means of a pair of hooks extending back from the tops of the relatively rigid members, received in slots of the chair frame, and by bolted connections of the relatively rigid members at the front of the seat portion to the chair frame. The seat-back unit, and particularly the relatively rigid frame members, are put into a pre-stressed condition as the seat portion is connected to the chair frame. Covering material, which may be removable, is positioned over the seat-back unit.

Each of two flanged frame juncture members has a horizontal top and a pair of vertical side flanges; the top has a pair of horizontal edges and each side has a pair of vertical edges.

Rear legs with integral back-support portions are welded to the other horizontal and vertical edges, so that they are spaced apart from each other farther than are the front legs. The rear legs may be two separate members or there may be a single continuous member including both legs and joined at the top.
