Unoriented polyolefin filaments are made from a composition comprising polypropylene, high pressure polyethylene or mixtures of these polyolefins the unoriented filaments having (a) a cross-section which consists of interconnected webs whose web length to web thickness ratios are at least 4: 1, or (b) a cross-section which is annular the radius to annular wall thickness ratio being at least 4 to 1. The filaments may have a cross-section which consists of interconnected webs, some of the webs having higher web length to web thickness ratios than the others so that the interconnected webs show unidirectional deformation when subjected to external stress. Preferably, the filaments have an overall cross-sectional area in the range of 0À010 to 0À400 sq. in. Brushes, and pillow and upholstery fillings, may be made from such filaments, which have better recovery characteristics than filaments of the same general configuration but different web length to web thickness ratios. Figures 1-9 (not reproduced) illustrate various filamentary forms. The filaments are made by known methods, a melt being extruded directly into water. Strains so introduced are relieved by annealing at elevated temperatures, e.g. 212 F. for high pressure polyethylene and 300 F. for polypropylene. Such annealing also assists in the production of completely straight filaments.

Abstract: 898,808. Road vehicle independent suspensions. DAIMLER-BENZ A.G. Nov. 30, 1960 [Dec. 4, 1959], No. 41182/60. Class 108(2). A wheel guiding arrangement comprises two longitudinal links, one extending forwardly and one rearwardly, articulated to a wheel carrier or axle at points substantially in the same vertical plane and a wheel or axle centre which is offset from the said vertical plane. Preferably the links 11, 12 slope upwardly from pivots C, D on the carrier 10 to pivots A, B on the vehicle frame and the wheel centre is offset to the rear of the pivots on the carrier. By connecting the suspension spring between the lower link and the vehicle frame the suspension stiffness increases with normal upward deflection whereas the effective damping of a damper fitted to the wheel carrier on the opposite side to the pivots increases on movement from a middle position. When the spring is mounted directly on a forward extension of the carrier the spring rates increases again with maximum downward deflection. Alternatively the lower link may comprise a quarter-elliptic leaf spring or part of a halfelliptic leaf spring or the spring may be fitted between an extended lower link and the upper link when using a compression spring or between the lower link and an extended upper link when using a tension spring. Further a pneumatic spring may be used in conjunction with resilient longitudinal links. In Fig. 8 a pair of lower links 11 is connected to the ends of an axle casing 19 and a triangulated upper link 22 is connected to the top of the differential housing 20, all three connections on the axle casing being in front of the axle centre-line. To reduce vehicle pitching during braking and acceleration, Fig. 12, the front suspension, incorporating triangulated links 111, 112, and the rear suspension are arranged so that lines extending through the points of contact 31, 32 of the wheels .with the ground and the instantaneous centres of movement Mu, MH of the wheels. intersect at a point 33 at the height of the vehicle centre of mass S.

Abstract: 1407082 Vehicle window operating mechanism GENERAL MOTORS CORP 7 Sept 1972 [13 Sept 1971] 41494/72 Heading E2M  In a vehicle window regulator 28 comprising  a handle 62 supported on a door 24 of a vehicle body for pivotal movement about a  fixed axis through a predetermined angular range less than 180‹, a lift arm 66 is mounted on the door 24 and pivotable in unison about the same fixed axis as the handle such that when the handle and lift arm are rotated a flexible drive member 84 of finite length is adapted to transmit forces in tension and compression through channel-shaped guide members 79, 80 on the door which provide a guide path for the drive member 84. As shown, the window regulator includes a support plate 44 rigidly attached to the inner portion 32 of the door and supports a one-way clutch 48 which operates to permit unitary rotation of the handle 62 with the lift arm 66 when a rotary force input is applied to the handle whereas when a rotary force input is applied to the lift arm the clutch 48 is looked to prevent rotary movement of the lift arm and the handle. When it is desired to close the window, movement of the handle 62 through an angle of less than 180‹ will cause pivoting of the lift arm 66 and the force applied to the drive member 84 will cause the window to be opened. The weight of the window places the drive member in compression when the window is in its closed or any intermediate position and results in a rotary force input at the lift arm which is resisted by the clutch 48.
