Abstract: ROCK BIT CONE RETENTION MEANS     ABSTRACT OF THE DISCLOSURE      A rock bit cone retention means is disclosed which primarily utilizes a series of segmented rings.  The segmented rings are inserted into a relatively deep annular channel formed transverse to the axis of either a journal or a cone of a rock bit leg assembly.  The complementary chan-nel, shallow in depth, is formed in either the journal or the cone.  The cone, when properly posi-tioned on the journal, closes out the channel formed in both the cone and the journal.  Upon assembly, the segments are urged within the deep groove or channel in the journal or the cone such that each of the segments do not protrude beyond the bear-ing surface as the cone is passed over an end of the journal.  Means are provided adjacent the cone reten-tion segment to accept a spring biasing means to urge each segment away from the bottom of the deep groove in the journal or cone.  When the cone is placed over the journal, each of the segments, when they register with the complementary groove in the journal, snap into place, thus substantially locking the cone on the journal.

Abstract: ABSTRACT          "Microwave oscillator"     A microwave oscillator suitable for millimeter wavelengths comprises a Gunn diode (3) coupled to a waveguide (1) by a resonant-cap structure (5,6). The diode (3) generates microwave energy both at a fundamental frequency fo which is below the cut-off frequency of the waveguide (1) and at a second harmonic frequency 2fo above cut-off.          To control the generation of microwave energy at 2fo, energy at fo may be coupled into the waveguide (1), e.g. from an adjacent further waveguide (9) above its cut-off, by means of an electric probe (8) extending close to the cap (5). The probe (8) may couple in a locking signal at or close to the free-running value of fo from another oscillator having better noise performance and electronic tuning, thereby locking 2fo to twice the frequency of the locking signal, or alternatively may couple to a varactor-tuned cavity resonant at fo.

Abstract: TITLE            MODULAR MIXING APPARATUS INCLUDING INTERCHANGEABLE FLUID                   PROCESSING MEANS     ABSTRACT           A helically moving fluid body leaving an extruder screw and brought into contact with rotating shearing means, undergoes laminar displacement, is then guided through a stationary sleeve along undulating linear paths of travel of relatively short axial length, and thereafter undergoes further laminar displacement and discharges into a die.         During movement of the fluid mixture along the undulating linear paths of travel subdivision and blending of substantially all of the material in the fluid body, which is not in a fluid state, takes place.  Thereupon the blended mixture is advanced to a die member at a desired fluidity and temperature in response to die requirements.  Heating of the barrel is significantly reduced and energy conser-vation of an appreciable nature is achieved.         In carrying out mixing as noted above there is em-ployed a modular mixing apparatus constructed with multiple processing means suitable for shearing, kneading, flow diverting, dispersing, blending and the like.  The multiple processing means includes a basic component assembly with which other components may be employed interchangeably to deal with varying types of fluid or plastic bodies wherein solid material may be present.

Abstract: ABSTRACT OF THE DISCLOSURE:           Device for exposing and separating photographic strip-material for the production of marginless copies having a roller-blind shutter comprising two shutter-curtains with accompanying shutter-rollers adapted to be driven by stepping motors.  The strip-material is transported and posi-tioned, along the path of travel of the said shutter-curtains, by a positioning roll also driven by a stepping motor.  Step-ping motors are controlled digitally by pulses from position-ing devices.  Prior to exposure of a section of strip by a projected picture, the strip-material is positioned in such a manner that its leading transverse edge is spaced by half a frame-length from the optical copying axis.  In order to make an exposure, the said shutter-curtains are moved con-secutively in the same direction, so that the closing edges thereof expose and then cover the said section of strip.  The one edge of the exposed picture is formed by the transverse edge of the strip-material, while the opposing edge is masked by the shutter-curtain located on the other side of the optical copying axis.  In the exposure-position, the closing edge of this shutter-curtain is spaced by half a frame-length from the optical axis of the picture.  The device may be adapted to different frame lengths by altering the pro-gramme of the positioning devices.

Abstract: "POROUS INORGANIC CARRIERS BEARING A GROWTH OF   MICRO-ORGANISMS - PROCEDURE FOR IMMOBILISING MICRO-ORGANISMS AND CARRIER BODIES SUITABLE FOR         THIS PURPOSE"                         ABSTRACT OF THE DISCLOSURE          For the immobilisation of micro-organisms and animal cells, in particular for anaerobic processes, such as the purification of waste water or for the biotechnological production of nutrition-essential and pharmocological substances, porous sintered bodies are employed as inorganic carrier bodies.  In particular sintered glass in the form of Raschig rings with a double-pore structure, are employed, which are characterized by porosity-determining through-going macropores that permit a free exchange of fluid and gas from the interior of the carrier to the surroundings, and by open microporus within the macropore walls, the diameter of the micropores being of the same order of magnitude as the size of the micro-organisms or cells.  These carrier bodies have an open pore volume of 35% to 85%, 20% to 80% being accounted for by the macropores having a diameter of 20 to 500 µm , and 15% - 5% by micropores having a diameter of 1 - 10 µm. These bodies are obtained by sintering a powder mixture comprising fine-grain material and a coarse-grain substance melting at a higher-than-sintering temperature and separable from the sintered product, allowing the latter to cool and separating (dissolving) out the soluble component.
