Title: Reaction tube for an exothermic heterogeneously catalysed gas reaction
Inventor: SCHIEBAHN HEINRICH JOSEF RUDOL
IPC: B01J8/06
Filed: 1983-12-19
Abstract: A reaction tube (1) for carrying out reaction between components of a reaction gas is filled with solid catalyst particles (3). The tube is subdivided into two successive sections, and in the upstream section (7) the ratio of the hydraulic tube diameter to the "equivalent diameter" of the catalyst particles (a dimension equal to the diameter of a sphere of corresponding volume) is smaller than the corresponding ratio for the downstream section (10) of the reaction tube. Additionally the upstream section (7) cooled, and is given a length such that the gas in it after reaching a maximum permissible reaction temperature can be cooled sufficiently prior to entering the downstream section (10) that the temperature in the downstream section remains below the maximum permissible temperature. The hydraulic tube diameter may be varied by mixing filler bodies with the catalyst. The reaction tube is especially suited to a methanation reaction performed on a synthesis gas containing carbon monoxide, carbon dioxide and hydrogen. <IMAGE>

Title: Measurement of profiles of irregular objects
Inventor: KYRIAKIS JOHN
IPC: B29C48/92
Filed: 1984-04-16
Abstract: The profile of an irregular shaped object is measured in an in-line extrusion process. This entails passing the object through an optical measuring gate which is rotated around the material, as the material intercepts the path of the beam across the gate. The intercepted beam is then monitored by suitable means to determine the shape of the profile. This assists inter alia in maintaining control of the size of the material and conformity to the required specification. The measuring gate includes a light source which directs a beam towards a photocell, the source and photocell being mounted on rings which are reciprocated through angles of 180 DEG  around the object as it is extruded. The thickness of a coating on the object may be determined by using respective apparatuses to determine the object's diameter before and after coating. The object may be an electrical cable. <IMAGE>

Title: Non-volatile electronic counters
Inventor: FINKELSTEIN NATHAN GARY
IPC: H03K21/40
Filed: 1985-09-06
Abstract: Electronic counters have a number of digits indicating the count value, each digit being coded by a group of bits at a particular location in the memory. Non-volatile memories, however, have constraints on the maximum number of Write cycles each memory location can undergo. The least significant digit undergoes far more Write cycles than the more significant digits. Therefore, by permuting the digits between the physical locations in the memory, the number of Write cycles to which each location is subjected can be optimised. The digits are permuted at predetermined count intervals so as to tend to equalise the number of Write cycles undergone by each location.   <IMAGE>
