Abstract: ABSTRACT          "Catalyst"      The  invention  relates to  a  nickel containing catalyst composition of high thermal stability and which has outstanding resistance to carbon deposition,  and is particularly but not exclusively for use in the steam reforming of hydrocarbons.   Nickel catalysts formed from coprecipitated materials and homogeneous on a microscopic scale are commonly used for the production of SNG by the low temperature steam reforming  of  liquid  hydrocarbons.   Similar materials may be used for the methanation of carbon oxides.  These processes require catalysts of high activity at relatively low temperatures.  Normally, the thermal stability and other physical parameters such  as  mechanical  strength,  and  abrasion resistance of such catalysts are of secondary importance.  The object of the invention is to provide an improved catalyst, which object is met by  a  catalyst  derived  from  a  precursor  of approximate chemical composition Ni6AlxLay (CO3)  (OH)12+2(x+y)nH2O   where x is not less than 1 and not greater than 4; y is not less than 0.05 and not greater than 1.5 and n is approximately 4.

Abstract: ABSTRACT OF THE DISCLOSURE:         This invention relates to a process for the iso-thermal absorption of the ethylene oxide contained in the gas from an ethylene oxide production plant.  This process is characterised in that the gas is firstly cooled to a temperature of between 5 and 60°C, and is then fed at a pressure which can vary from 1 to 30 ata to a water-fed isothermal film absorber, from the bottom of which is ob-tained a high concentration ethylene oxide solution which can be fed directly to the glycol production plant after recovering the ethylene still in solution.  By means of this process, the absorption plant is simplified compared with known processes, and steam, electricity and cooling water consumption are considerably reduced.

Abstract: LIQUID TREATER HAVING              ELECTRICAL CHARGE INJECTION MEANS                  Abstract of the Disclosure The treater is provided with oppositely charged electrodes which cause liquid passing through the treater to be exposed to an electric field.  At least one of the electrodes includes a distribution of sharp projections which protrude outwardly therefrom toward the opposite electrode.  Such projections are all provided with outermost, conical tips that serve to inject charge carriers into the liquid at an acceler-ated rate if the treater is electrolytic in nature and serve to focus or concentrate the electric field if the treater is electrostatic in nature as a result of the two electrodes of the treater being electrically insu-lated from one another across the liquid being treated.

Abstract: ABSTRACT         A control system for electronic discharge machine includes an automatic relay control in which machining pulses are a step function of machining cycle period and higher frequency pulses are held to a lower current level to avoid power transistor overload.  The relay control circuit also includes a threshold responsive circuit which senses any change in relay controlling output signals and acts to interrupt machining pulses briefly to allow time for relay operation.          A current cutoff control circuit detects abnormally low voltage across the machining gap and reduces gap discharge energy level.          Pulses referred to as "probe pulses" replace the normal master pulses to control gap discharge time duration and time spacing.          A logic circuit controls probe pulse duration relative to master pulse duration.  It provides for further lowering probe pulse energy by squelching probe pulses periodically if the master pulse period is below a certain time.

Abstract: ABSTRACT OF THE DISCLOSURE An addressable subscription television decoder includes an input stage including an IF amplifier for converting a scrambled RF television signal to a composite baseband video signal. The baseband video signal comprises either a nominal sync component or a sync component having suppressed horizontal sync pulses during video fields and having non-suppressed sync pulses during vertical intervals, the vertical intervals also including selected encoded data signals. An AGC voltage for controlling the gain of the IF amplifier is developed by a circuit exhibiting a relatively short time constant whenever the composite baseband video signal is characterized by nominal level sync pulses, the time constant being increased in response to suppressed horizontal sync pulses. The sync pulses produced during the vertical intervals of the composite baseband video signal are thereby not subjected to excessive IF gain for facilitating processing of the data signals by the decoder.

The coil is finally decoiled out of the upstream coiling furnace and passed through the finishing train which has been reset to the appropriate roll gaps during the intermediate rolling stage between coiler furnaces. In a second embodiment a single coiling furnace is employed and the workpiece is coiled in the upstream coiling furnace and then passed through the reversing mill and the finishing train. In a preferred embodiment initial and/or intermediate passes are taken in tandem to reduce time and temperature losses.
