Title: Double heat exchanger for exothermic reactions - has set of tubes contg. catalyst which act as reactor tubes, with bundle above and below, having heat transfer medium around tubes
Inventor: DUEMBGEN GERD DIPL CHEM DR
IPC: B01J8/06
Filed: 1979-01-31
Abstract: Tubular reactor is for carrying out gas phase catalytic reactions. Two tube bundles are used above and below a common inlet branch (or outlet). The gas stream divides and flows out from either end of the vessel. On the cooling side, distributor plates are used to give uniform coolant flow along the walls of the tubes. The apertures on these increase towards the centre. A further baffle is used in the cooling side at the level of max. heat release. Used for strongly exothermic gas phase catalytic reaction. Can also be used on endothermic reactions. The capacity is not limited by the heat transfer factors nor by the construction.

Title: Integrated ROM programme store for microprocessor - has split memory to accommodate various word lengths with optimum access speed
Inventor: MACMILLAN RICHARD WALES
IPC: G06F9/26
Filed: 1979-02-28
Abstract: The programmable read only memory in either ROM or PROM form used to store resident software in a microcomputer system, is designed to enable a long word length capacity with placing limitations on operating speed when short word lengths are used.
