Abstract: ABSTRACT     CARBON GASIFICATION     The present invention relates to generating a hot gas consisting primarily of CO and H2 from a carbonaceous starting material which, in pulverulent form, together with oxidizing agent and optionally also a slag former, is introduced into a gasification chamber, where it is combusted and partially gasified.  The resultant gas mixture is then introduced into a shaft containing a bed of solid carbonaceous lump material.  The physical thermal content of the mixture emerging from the gasification chamber is used in the coke bed to reduce the content of carbon dioxide and/or water in the gas.  The gas generating process is controlled so that the gas leaving has a temperature and a composition suitable for a following process step.

Abstract: ABSTRACT OF THE DISCLOSURE           A method and apparatus for precisely controlling plastic strain rate during plastic deformation testing of a solid material such as a metal or plastic are described in which the effects of elastic strain rates associated with the specimens and machines used for such testing are eliminated by applying corrections proportional to the load on the specimen.  Thus strain rate sensitivity, unaffected by the machine or specimen modulus can be measured.  Strain rate sensitivity can be used to measure the activation volume of the specimen which may be used for quality control of material processing and/or manufactured articles.

Abstract: Abstract A method of detecting the presence of an indicating device in a restricted investigation zone, comprising the detecting of an in-dicating device (31) of a highly permeable material by emitting and receiving a magnetic field, where two coils (1,2) are caused to emit a high-frequency magnetic alternating field, and a first one of the coils (1) emits an alternating field with a frequency (f1) different from the frequence (f2) of the field emitted by the second one of the coils (2), and at least one difference and/or sum frequency n ? f1 + m ? f2 occurring by intermodulation by means of the indicating device (31), where n and m are positive or negative integers, is caused to be received by one or several coils (9). According to the invention, a third low-frequency magn-etic alternating field is caused to be emitted in said zone with a frequency (f3) substantially lower than the frequencies (f1,f2), which low-frequency field is caused to have a field intensity sufficiently high, independently of the fields with the frequenc-ies f1 and f2 to put the indicating device (31) into saturated condition in step with the frequency of the low-frequency field. A field re-emitted from the indicating device (31) hereby is detected by means of a detector device as an intermodulation occurring periodically with the frequency of the low-freuency field between the frequencies f1 and f2.

Abstract: Process and apparatus for the removal of liquid from a solid parti-culate material.          Abstract In a process of removing liquid from a particulate solid material the material is passed through a row of upwardly open, elongated interconnected cells and superheated steam is introduced into said cells at their lower ends in a manner so as to impart to the particles a whirling movement, during which dried particles are lifted out of the cells and into a common transfer zone and from said zone down into a discharge cell with no steam supply. The dried material thus introduced into the discharge cell is discharged together with material which has passed the row of cells. The invention eliminates the need for effecting a preceding disintegration of the solid particulate material.

Abstract: ABSTRACT      An apparatus suitable for use in the substantially continuous production of cheese from milk retentate in which there is at least one, preferably several, coagulator tubes having an inlet end and an outlet end.  The retentate is admitted to the tube from a feed system via the inlet, forms a coagulum inside the tube and is discharged from the outlet whereupon it is cut or sliced into appropriately sized pieces, preferably small cubes by a blade assembly mounted at or near the outlet.  The feed system comprises a distribution manifold for delivering retentate to the inlet or inlets via a valve located between the manifold and tube(s) and a pump for circulating the retentate in the feed system at such a rate that the feed system is substantially free of coagulum.

Abstract: ABSTRACT                  A process for isotopically labelling certain chemical compounds, with a selected or desired isotopic label comprising first treating a precursor material with the isotopic material to exchange the hydrogen atoms of the precursor material with the isotopic material and then or simultaneously reacting the exchanged precursor with a chemical  compound so as to label the chemical compound with the isotopic material at a desired preselected location within the molecule of the chemical compound.  A typical example involves first forming deuterated Raney nickel and then reacting the deuterated Raney nickel with an organic compound under relatively mild conditions so that specific selective hydrogen-deuterium exchange occurs within the molecules of the chemical compound at a pre-selected location within the molecule.

Abstract: Abstract The invention provides a method for producing a glass preform for an optical fiber comprising forming a fine glass particle mass by flame hydrolysis of a glass raw material, dehydrating the fine glass particle mass in an oxygen atmosphere containing chlorine or a chlorine-containing compound at such a temperature that the soot preform is not considerably shrunk and heating the soot preform at a temperature at which the soot preform is sintered and made transparent.  The glass preform pro-duced by this method contains fewer hydroxyl groups and structural defects than conventional products.  Moreover, an optical fiber fabricated from the glass preform has stable light transmission characteristics over a long period of time.

Abstract: Abstract of the Disclosure A diaper fastener strip has a first zone coated with a release material and a coat of adhesive over the release material and a second zone coated only with adhesive.  The part of the strip having the second solely adhesive coated zone is adhered tenaciously to the margin of the fluid impermeable outer backing sheet of a diaper.  The part of the strip having the first release material plus adhesive coated zone is folded over the diaper margin to contact the adhesive with the margin of the inner fluid permeable sheet of the diaper.  When the strip is unfolded the adhesive transfers from the release material in the first zone to said inner sheet margin and becomes exposed for securing the diaper on a body.  An alternative strip has said adhesive coated second zone adhered to the backing sheet and two consecutive zones next to it. The first zone most remote from the second zone may have adhesive coated over a release coating so when the first zone is folded over a third zone between the first and second zones and the strip is later pealed back, there will be adhesive transfer to an exposed in said third zone for securing the diaper on a body.
