Abstract: ABSTRACT. Edge triggered flip flop".             A single flip flop is integrated with MOS cir-cuitry which enables the single flip flop to be triggered by each of several individual clocked functions without interfering with one another.  The flip flop responds only to low to high transitions of each clock signal input. This is accomplished by feeding back the flip flop output to each trigger circuit in such a way as to temporarily disconnect the trigger circuit from the flip flop during the time period between two successive low to high transit-ions of a particular clock signal, so that the flip flop can be triggered by other clocked functions without inter-ference from the particular clock signal.

Abstract: AUTOMATIC BLAST ACTUATED POSITIVE                 Michael L. Leigh RELEASE MYSSILE DETENT   Richard D. Stubbs ABSTRACT OF THE DISCLOSURE A missile or rocket detent and positive release mechanism actuated  by the rocket's thrustor.  The mechanism is mounted on the outside of a rocket launcher tube and the notched-end of a spring-loaded lever extends into the launch tube for positively locking a rocket into place.  The lever has a centrally located pivot point and a cam at the other end.  One end of a sear is connected to a second lever which extends into the rocket's blast region.  The other end of the sear has a cam actuating surface which is disposed against the first lever's cam.  The blast from the rocket's thrustor pushes the second lever around on its pivot point such that the sear actuates the cam-end of the first lever, rotating it a small distance on its pivot point thereby withdrawing its notched-end and releasing the rocket.

Abstract: ABSTRACT OF THE DISCLOSURE          In the manufacture of ethylene oxide by the partial oxidation of ethylene in the vapor phase, the effluent gases from the reaction are absorbed in ethyl-ene carbonate prior to separation and purification of the ethylene oxide.  The ethylene oxide is then separated from the ethylene carbonate by heating the latter with a heated, inert stripping gas, i.e., CO2 or nitrogen.         This process provides advantages over the use of water as the absorbent because the heat requirements are reduced and smaller apparatus and equipment can be used.   26,616-F                    -9-

Abstract: Abstract A process and apparatus for contacting a fluid with the walls of a vessel are characterised by flow of the fluid alternat-ingly (a) through a structure within the vessel and having passages angled to the general direction of flow in the vessel and (b) through a space between the structure and the vessel walls. The structure can be for example a cross flow ceramic or metal honey-comb or a stack of profiled plates or of apertured plates such as expanded metal. The structure can carry a catalytic coating and then affords high activity and low pressure drop. The process and apparatus are especially suitable for endothermic tubular steam hydrocarbon reforming.          According to figure 1 a cylindrical vessel has, separated from its inner walls by annular-section space 12, a structure con-sisting of elliptical flat plates 14 alternating with elliptical corrugated plates 16, all mutually parallel and set at an angle of 30° to the general fluid flow direction. The relative pressure drops through the passages and through space 12 are adjusted so that fluid flows through the passages between the flat plates and corrugated plates and then, on emerging from those passages, through the space 12 in contact with the vessel walls until it encounters the opening of further passages.
