Title: Method for the removal and recovery of promoter from crude phthalic anhydride made by the vapor phase oxidation of orthoxylene in the presence of promoter
IPC: C07C51/573
Filed: 1967-06-07
Abstract: HBr is obtained from crude phthalic anhydride made by the vapour phase, catalytic. air oxidation of o-xylene in the presence of a bromine promoter by heating the crude phthalic anhydride to an elevated temperature and keeping it at said elevated temperature until evolution of HBr substantially ceases, to thereby drive off dissolved hydrogen bromide water vapour and low boiling impurities and to decompose heat - decomposable bromine adducts into hydrogen bromide which is driven off as vapour, and thereafter stripping residual HBr from said heat-treated phthalic anhydride by passing it through a fractionating stripper column in countercurrent flow with phthalic anhydride vapour whereby said phthalic anhydride vapour strips said residual HBr from said heat-treated phthalic anhydride. The HBr from the heat treatment step may be recycled for use as a bromine promoter in the catalytic oxidation of o-xylene to phthalic anhydride. Sulphuric acid may be added to the crude phthalic anhydride before subjecting it to heat treatment and the stripping step may be carried out in the presence of inert gas and at elevated pressure. Apparatus for carrying out the process is described with reference to a drawing (not shown).

Title: Fluid Pressure Servomotor of the Vacuum-Suspended Type, adapted for Superatmospheric Pressure Operation
IPC: B60T13/56
Filed: 1968-02-02
Abstract: In a fluid pressure servomotor of the vacuumsuspended type for braking systems a housing, consisting of a front shell 10 and a rear shell 12 joined together by a twist lock connection 14, houses at least one plastics pressure differential responsive movable wall 22 reciprocally mounted within the housing and a valve device located within a tubular portion 28 of the movable wall 22 projects outwardly through an opening in the housing, the valve device being operatively connected to an operator-actuated push rod 113 adapted to communicate the interior of the tubular portion to the control chamber side of the movable wall upon actuation of the push rod, the servomotor having means for preventing the interior of the tubular portion from communicating to atmosphere and establishing communication to a source of superatmospheric pressure air via connection 120 an a hollow portion 108 of the push rod. In operation, when the brake pedal is depressed a reaction plunger 72 moves inwardly under the action of the three-part push rod assembly 108, 110 and 113 to close the gap between a head 74 of the plunger and a deformable disc 30. At the same time a valve flange 76 on the movable wall 22 closes off vacuum suspension of the chambers on either side of the wall 22 and a diaphragm 18. Further inward motion of the brake pedal causes further inward motion of the reaction plunger 72 to remove the valve seat, formed on the rear face of reaction plunger 72, from the valve face 86 of the poppet valve to communicate the chamber to the radial passage 166 through the tubular portion 28 to allow super-atmospheric air from a reservoir 122 to create an immediate pressure differential across the wall 22 and the diaphragm 18 to project the force transmitting rod 36 forwardly and pressurize a master cylinder 40 to apply the vehicle brakes 46. Fig. 3 shows an alternative embodiment wherein a cup-shaped structure 152 is secured to the servomotor housing 12b and is connected via a fitting 154 to the source of super-atmospheric pressure air. In this case the push rod 158 is not formed with a hollow connection and a standard valve arrangement 72b is utilized. The push rod 158 is located in the end of the cup-shaped housing 152 through a sealing plate 160 which is arranged to be held between a plate 162 and an inwardly-turned flange 164 of the housing 152 to permit radial movement of the sealing plate 160 to accommodate arcuate action of the push rod 158.

Title: Resilient railway truck suspension
IPC: B61F3/04
Filed: 1973-06-25
Abstract: A resilient railway truck and vehicle suspension provides soft body springing while reducing axle to axle load transference. The axle-supported truck frame swivelly mounts a transverse sub-bolster and a transverse bolster is carried on the sub-bolster by elastomeric pad devices oppositely inclined longitudinally of the truck so that their normals intersect at a level below the axles, preferably about rail level. The bolster supports the body by upright springs at each side of the truck and is restrained against longitudinal movement or tilting movement about its transverse axis with respect to the body so that tipping movements of the truck relative to the body including those necessary to accommodate to changes in vertical track curvature occur about the intersection of the elastomeric pad device normals, thereby reducing or eliminating any vertical moment arm through which the tractive forces might act on the truck to cause objectionable axle to axle load transference.
