Abstract: 1394520 Semi-conductor devices WESTINGHOUSE ELECTRIC CORP 21 Nov 1973 [29 Nov 1972] 53974/73 Heading H1K A light sensitive semi-conductor array comprises light sensitive cells 10 arranged in rows and columns, each row having an adjacent CCD shift register 22 leading to a further shift register 40 at the end of the rows, from which a video signal, derived from the carriers generated in the cells, is obtained. In an embodiment, a silicon substrate provides the sensor cells 10 each with a sensor element 12 defined by a partially encircling stopper diffusion 14 of the same conductivity type as, but of higher impurity concentration than, element 12, and a complex pattern of electrodes 24, 26 is produced on the substrate using two insulating layers 82, 96. Each electrode forms a conductive track of the two-phase CCD shift register 22. A third conductive track 16 is produced on the top insulating layer 96 to transfer charges from the element 12 to the shift register. This transfer is aided by a transparent polycrystalline silicon electrode 84 overlying the element 12 but separated therefrom by the first layer 82. Overlapping of electrode areas extending from the conductive tracks enables close control of the carriers preventing degradation of signal. The insulating layers may be of silicon dioxide, the electrodes 24, 26 and 16 of aluminium. The use of PN junction diodes as the sensor elements 12 is described.

Title: Process for catalytic refining of hydrocarbons containing organic sulphur compounds
IPC: C10G45/06
Filed: 1965-12-22
Abstract: Process for the catalytic refining of hydrocarbons, such as petroleum distillates and gaseous hydrocarbons, containing organic sulphur compounds, comprises forming a vapour mixture of such hydrocarbon and water that accounts for one-half to two-thirds of the volume of the mixture, and passing such mixture at a temperature in the range 250 DEG  to 450 DEG  C. and at a positive pressure of up to 40 atmospheres through a reactor charged with a highly active nickel catalyst (defined) with a space velocity in the range, approximately, 200 to 500 standard cubic metres per cubic metre per hour, the conditions in said reactor being such that from 1 to 3% of said hydrocarbon in the mixture is converted to hydrogen, methane, carbon dioxide and carbon monoxide whilst the sulphur compounds, any nitrogen compounds and any unsaturated compounds in said mixture are hydrogenated, the hydrogen sulphide so produced being absorbed by the catalyst which, when hydrogen sulphide appears in the gas leaving the reactor, is removed from the process and regenerated with superheated steam at about 400 DEG  C.  The highly active nickel catalyst is defined as a catalyst in which a nickel compound reducible with hydrogen at a temperature above 250 DEG  C. is applied to a carrier substance in very finely divided form.  In order to obtain desulphurization to less than 1 p.p.m., a two-stage process may be used, the two stages both operating under the specified physical conditions, only the catalyst in the second stage being subject to removal and regeneration.  An example describes the desulphurization of gasoline.

Title: Method and device for the supervision of an electrical control system, especially of a safety switching system of a nuclear reactor
IPC: G21C7/36
Filed: 1965-12-29
Abstract: 1,108,258. Controlling reactors. GESELLSCHAFT FUER KERNFORSCHUNG m.b.H. 29 Dec., 1965 [31 Dec., 1964], No. 55033/65. Heading G6C. A nuclear reactor safety switching system is tested by testing values fed into the system . (input testing values) being compared with values taken out of the system (output testing values), which latter values are functionally dependent upon the input testing values, so as to form common values (disturbance quantities) and by a correction operation being initiated as a function of the disturbance quantities counteracting any possible faults arising in the system. The system is repeatedly tested automatically in predetermined time intervals by means of testing values in a digital pulse form which operate similar to short shutdown quantities of the system. The time between the testing events (test cycle) including the time up to the initiation of the correction operation is shorter than the time between the input of measured variables in the safety system and a resulting shutdown (response time). Advantageously, the correction operation is used to change a disturbed " m-out-of-n " switching system to an undisturbed "p-out-of-q" switching system, where m, n, p and q are whole numbers and m # n, p # q and q # n. The safety switching system may comprise several identical switching devices (safety channels) for the generation of a quantity resulting in reactor shutdown, a group of n identical reactor parameter (e.g. neutron flux) measurement devices being assigned to each safety channel, and, in addition, each safety channel comprising n identical smaller switching devices (safety lines) which, in turn, are assigned one each of the n measurement probes. Each safety line consists of one critical value unit and one reference unit to compare the measured values from each group of probes (line values) with preset critical values and to compare the deviations among the individual line values with a preset value of deviation, respectively, as well as a logic circuit device for logically connecting the output values of the critical value and reference units of the safety channel in question to generate a shutdown signal.

Abstract: 1,187,766. Sterilizing liquqid foods. UNILEVER Ltd. 6 Dec., 1967 [9 Dec., 1966], No. 55223/66. Heading A2D. In sterilizing liquid foods (e.g. milk, cream, soups, fruits or tomato juices and slurries containing meat, vegetable or fruit solids) the liquid is formed into at least one stream and the stream is heated to at least 100‹C. (e.g. by microwave radiation or alternating electric current) while it is free from contact with a solid surface and then cooled by mixing it with a cool steril liquid while maintaining it free from contact with a solid surface (e.g. by impinging the stream with jets of precooled sterile liquid or my passing the stream into a container of pre-cooled sterile liquid). The process may be carried out at superatmospheric pressure. In the apparatus shown, which is sterilized by passing live steam from pipe 52 through it and is pressurized with oxygen-free nitrogen provided by gas cylinder 53, a stream of liquid supplied under pressure through pipe 42 is heated by microwave radiation as it is passed through radiation transmittent ceramic tube 18 without contact therewith, passed through limb 26 of housing 25 to chamber 33 where it is cooled by being mixed with precooled sterile liquid from inlet tubes 35 and passed to reservoir 37 from which some cooled liquid may be passed through refrigeration unit 49 to inlet tubes 35. Initially the stream is deflected by pivotal scoop 28 through limb 27 of housing 28 till the desired temperature is registered by thermo-couple 31 which is then removed from housing 25 and the scoop 28 is deflected to allow the stream to pass through limb 26. The power of the radiation produced by energized magnetron 56 and passed along wave guide 14 is matched to the load of the stream by adjusting pistons 20, 21 and 22.
