Title: Suspension means for chassis frames
IPC: B60G21/055
Filed: 1935-08-17
Abstract: 440,554. Vehicle spring-suspensions. M.G. CAR CO., Ltd., and RENWICK, W. S., Pavlova Works, Abingdon-on-Thames. Aug. 17, 1935, No. 23113. [Class 108 (ii)] An anti-roll device connecting the wheel-suspension means on either side of a vehicle comprises a loaded spring means which becomes further stressed when either wheel rises or falls relatively to the frame more than the other, such further stressing biassing the other wheel to rise or fall also, no effect being produced when both wheels are at the same height relatively to the frame. Various arrangements are described. As shown in Figs. 1, 3 and 4, the wheels are suspended by links 14, 15 with a torsion spring arranged longitudinally at 17. Bell-crank levers 18, 19 are connected to the lower links 15 and to a transverse anti-roll device comprising a torsion bar 24 and two part casing 20, 21, the right hand wheel suspension being connected to casing 20 and the left-hand suspension to casing 21. The torsion bar 24 which is stressed, is connected to the casings by pegs 25, 26 which enter clearance slots 27 in the inner and outer casings. If the left-hand wheel rises more than the right-hand wheel turning the outer member 21 counterclockwise the outer member 21 engaging the peg 26 will turn it counterclockwise while the peg 25 will ride idly in the slot 27 in the outer member, the peg 25 being held by the inner member 20 and therefore the torsion bar 24 will be further stressed biassing the right-hand wheel to move in the same direction as the left-hand wheel. Fig. 10 shows an arrangement employing two stressed coil springs 52, 53. Movement of either of the cranks 41, 41<a> will compress one of the springs 52, 53, the other spring being held in its original stressed condition by the central abutment on either the rod 45<a> or the casing 50.

Title: Improvements relating to the manufacture of tubes and tubular films
IPC: B29C48/09
Filed: 1961-06-28
Abstract: <PICT:0938032/IV(a)/1> <PICT:0938032/IV(a)/2> <PICT:0938032/IV(a)/3> Tubular films are made from a thermoplastic material which is shaped by means of an extrusion head and is, as it flows through the head, severed at one or more places by a mandrel or a mandrel support arranged in the head and then re-united.  The severed flowing mass is subjected at the corresponding cut edges to different velocities by means of oblique guide surfaces, the setting angle of which varies in the direction of flow.  As the material passes the mandrel or the mandrel support edges of material flowing at lower velocity are re-united with edges flowing at higher velocity and conversely at this different energy state.  As shown in Fig. 1, the thermoplastic material flows through the annular duct 3 of an axial extrusion head in the direction of the arrow and is severed by the fixed radial vanes 4 supporting the mandrel 2 in the housing 1 into several individual streams which re-unite behind the ends 6 of the vanes (Fig. 2). The vanes 4 function as guiding and mixing elements and their profile resembles that of a ship's hull the bow 5 and stern 6 of which are set in opposite directions relative to the longitudinal plane of symmetry of the material approaching the mandrel.  As shown in Fig. 3, the material flowing from the discharge duct 8 of a screw extruder is deflected into a duct 9 (of annular cross-section) which is at right angles to the screw axis and is there divided into streams by a mandrel 10 mounted, in the usual manner, in a sleeve-shaped supporting member 12 positioned in the housing 11 of the head.  The annular end surface 13 of the member 12 is in the form of a track curved so that it ends in an edge 14 which is directed as a secant to the curved surface of the member 12 and may be directed obliquely to the radial plane.  The oblique edge may be in two steps 15, 16 at different angles of inclination to the radial plane, as shown in Fig. 4.  The invention prevents the formation of longitudinal markings in the extruded tubes and tubular films.
