Abstract: Oxychlorination of ethylene is carried out using a three-reactor system containing beds of a catalyst comprising a spherical, high-surface area activated alumina impregnated with cupric chloride and potassium chloride. In the first two reactors, the catalyst bed is divided into two sections, with a more active catalyst in the lower section than in the upper. The catalyst is substantially undiluted with inert particles.A new catalyst for such a process is also provided.

Abstract: A latching device for luggage or the like cooperable with a hasp is constted so that a manually operable latch member is pivotally connected to a projection on a mounting plate for allowing the latch member to be rotated with respect thereto. A leaf spring biases the latch member into contact with the top surface of the projection. The projection includes stop surfaces for limiting rotation of the latch member in a first direction to a closed position wherein the latch member substantially overlies the mounting plate and for limiting rotation of the latch member in the opposite direction to an open position wherein the latch member is substantially perpendicular to the mounting plate. The leaf spring also biases a detent ball into contact with a surface of the latch member for releasably maintaining the latch member in the open and closed positions.
