Title: Power steering gear
IPC: B62D5/24
Filed: 1968-11-20
Abstract: 1,205,868. Power-assisted steering mechanism. CHRYSLER CORP. 20 Nov., 1968 [19 Dec., 1967], No. 55154/68. Heading B7H. Power-assisted steering mechanism comprises a rotatable worm 19, a piston 12 and an integral tubular extension 14 movable axially of the worm 19, a rocker arm 30 connected by a ball 32 and socket 37 to the extension 14, and a rotatable follower 21 engaged with the worm 19 and connected to the extension 14 separately from the ball 32 and socket 37. The follower 21 is journalled in a bushing 22 screwed into the extension 14 and is loaded by a spring 28. The socket 37 is held in an aperture 38 in the extension 14 by a retainer 39 secured by a bolt 40. The ball 32 has a conically-shouldered pin 33 secured in the rocker arm by a nut 34 and prevented from rotating by a radial pin 35. A flattened oblique diametral zone 32a on the ball 32 permits insertion of the ball into the socket 37. The rocker arm 30 is integral with a rocker shaft 31 which is permitted axial displacement against spring loading 50 so that the ball 32 can move transversely of the worm 19 as the extension 14 rotates about the worm axis to accommodate swinging of the ball about the rocker shaft axis. A tubular shaft 17 connected by a pin 18 and setscrew 20 to the worm 19 is coupled through a transverse pin 67 and torsion bar spring 66 to an input shaft 64. A rotary valve spool 57 connected to the input shaft 64 by a ball pin 65 co-operates with ports 76L, 76R in the tubular shaft 17 upon rotation of the input shaft 64 and consequent twisting of the torsion bar spring 66 to direct fluid supplied through an inlet 61 to the appropriate side of the piston 12 and to connect the other side of the piston to a fluid outlet 92. Lugs 64c on the input shaft 64 co-operate with lugs in the tubular shaft 17 to limit relative rotation of the shafts and provide for manual actuation of the mechanism in the event of power failure.

The rods or plates are welded or soldered at one end to an earthed central disc portion 9 of the bulkhead, but are insulated from each other at the other end where the bulkhead is supported by a ring 12. Rods of trapezoidal form may be used and the bulkhead may be reinforced by a glass fabric or boron carbon fibre layer (16, Fig. 4) which can be impregnated with a curable varnish or plastics, and sealed by an additional layer (16<SP>1</SP>). In another embodiment the rotors (6<SP>1</SP>, 7<SP>1</SP>, Fig. 5) and the intervening bulkhead (9, 10<SP>11</SP>, 11<SP>11</SP>) are all planar disc shaped, but the bulkhead may have other shapes, e.g. part-spherical. The energising stator winding 8 may be replaced by a winding applied to one of the rotors or by one or more permanent magnets; the coupling may be constructed of solid soft iron or laminated; and one of the rotors, preferably the driven one, may have a conductive metal layer or a squirrel cage armature in order to provide for asynchronous starting or running. The coupling may be, however, constructed for synchronous operation and the poles may be of the same or alternate polarities.

[Class 2 (iii)] Aromatic hydrocarbons such as benzene and toluene are obtained from an unsaturated hydrocarbon oil consisting essentially of hydrocarbons boiling in the gasoline range and containing at least 30 per cent. of olefins derived, e.g. from the products of the cracking of higher boiling hydrocarbon oils by separating from the oil a fraction containing hydrocarbons boiling in a close range including the boiling point of the desired aromatic, subjecting this fraction to catalytic aromatization in presence of hydrogen, separating a fraction boiling in the neighbourhood of the boiling point of the desired aromatic, extracting with a solvent for aromatic hydrocarbons, contacting the extract phase countercurrently with a non-aromatic hydrocarbon diluent having a boiling range different from those of the desired aromatic and the solvent whereby secondary raffinate and extract phases are formed, separating these and recovering pure aromatic. The catalyst for aromatization may be aluminium oxide and an oxide of a metal of Groups IV, V, VI or VIII. The solvent may be liquid sulphur dioxide, and the diluent a highly paraffinic oil of the type of pentane, iso-pentane or a saturated kerosene.

Title: Method for the continuous manufacture of banded leak-tight tubes and an apparatus for carrying out this method
IPC: B29C48/90
Filed: 1971-12-08
Abstract: 1345822 Extruded tubes J-J WALTER 8 Dec 1971 [11 Dec 1970 15 July 1971 (2)] 57045/71 Heading B5A [Also in Division F2]  In a method for the continuous production of banded leak-tight tubing an inner sheath 1 of leak-tight plastic material receives a jacket 2 comprising one or more windings of reinforcement material which is impregnated with a hardenable binder at station F and covered with an outer plastic sheath 3, thereby applying the binder intimately and uniformly against the reinforcement 2, the binder then being polymerized. Apparatus for carrying out the method, as shown, comprises a first extruder A which produces the inner plastic sheath e.g. of polyethylene over a mandrel (12) (Fig. 4, not shown). A cable 24 is attached at one end to the mandrel (12) and at the other end to a plug 25 at a stage where the tubing is completed and the intervening section of tubing is pressurized to support the tubing shape. Drive wheels B advance the sheath 1 to winding stations C, D, E where the reinforcement material 2c, 2d, 2e, e.g. threads, braid or ribbons with a glass fibre base, is wound helically over the sheath 1. At station F the tube passes through a doublewalled impregnating tank (53) (Fig. 8, not shown) over which a second extruder produces the outer plastic sheath 3. The impregnating binder may be a polyester or epoxy resin which may be catalysed and accelerated. Whilst the outer sheath 3 is hot the tube is drawn through driven wheels G which elongate the outer sheath to contract it over the reinforcement layer 2. The tubing is then supported over a hot air nozzle 72, passed through a compression collar 76 and over a cold-air nozzle 74 at a station I which effects further contraction of the outer sheath 3 over the impregnated reinforcement 2 to uniformly spread the binder. Traction belts 70, 71 at station H advance the tube through collars 77 at station J which improve the binder distribution before it is polymerized at a station K. The station K comprises an elongate enclosure having three adjacent compartments (86, 87, 88) (Fig. 11, not shown) part-elliptical in transverse section a source of U.V. light being disposed at a focus of each compartment. The tubing traverses the enclosure through a transparent tube (85) which is fan-cooled to remove heat generated by the polymerization of the binder. In alternative arrangements, the outer sheath is contracted by passing the tube through a reservoir containing liquid at a controlled temperature and pressure (Fig. 12, not shown) and the extruder at stations B or F may include a mandrel having a low-friction surface incorporating a continuous ball race (Figs. 13, 14, not shown). Other materials for the inner and outer sheaths are high or low density polyethylene, acrylonitrile butadiene styrene, P.V.C., polystyrene or polypropylene.

The adhesive may be a polyvinylbutyral sheet and the plastics material a sheet of cellulose aceto-butyrate. The plastics material may have alcoholic solution of tin chloride sprayed on the surface which faces the adhesive to favour adherence and its surface which contacts the protective sheet may have a coating of a polyurethane. The glass sheet and the protective sheet may be shaped by the same machine and may be toughened by chemical or thermal action. The protective sheet may have an anti-adherent coating (e.g. powdered magnesium stearate). The sheets to be laminated and the protective sheet may be assembled and placed in a sealed sack. The sack is placed in an autoclave and heated to around 70 C., when the sack is evacuated and the pressure in the autoclave reduced. The temperature of the sheets is raised to the laminating temperature and a superatmospheric pressure applied to the evacuated sack which may be maintained whilst the laminate cools.
