Abstract: ABSTRACT                 INJECTION MOLDING APPARATUS         Apparatus for forming objects from molten material includes a mold frame and a movable mold side having complementary faces that define molding cavities.          The mold frame includes a mold housing having an internally heated manifold which has a plastic distribution channel for feeding plastic to an injection nozzle passageway having a restricted discharge nozzle that discharges the plastic into a molding cavity.          Within the injection nozzle passageway is a heater probe which has an internal heater, preferably an electrical cartridge heater.  The probe is secured by an integral seating flange to the mold housing to hold the probe coaxially aligned in the injection nozzle passageway and to hold the probe against shifting with thermal expansion and contraction of the manifold.  The integral flange may be positioned at or adjacent the exterior of the mold so that it can be pulled outwardly to remove an elongated body of the probe from the nozzle passageway for easy replacement of the internal cartridge heater disposed within the interior of the probe.  The electrical caryridge heater is substantially lower in cost than external electrical band heaters used heretofore for heating plastic flowing internally through a probe.

Abstract: CALIBRATION METHOD AND APPARATUS     FOR OPTICAL-RESPONSE TISSUE-EXAMINATION INSTRUMENT                ABSTRACT OF THE DISCLOSURE   A method and apparatus for calibrating optical-response tissue-examination apparatus, and for operating the apparatus as calibrated, in which a novel calibration device is coupled between the sending and receiving components of the optical-response equipment and the equipment is then run through a test cycle of its operation with the calibration device in place and in effect constituting part of the system, to thereby project selected light spectra into the calibration device and receive such light as it emerges from the calibration device.  The calibration device provides known, standardized light-transfer characteristics (diffusion and attenuation) which condition the detected emergent light energy in a known and precisely repeatable manner, whereby such conditioned light energy may be used to analytically characterize the optical response apparatus itself.  In preferred embodiments, the calibration device incorporates selectively changeable media samples disposed across the path of light travel through the calibration device, whereby the emergent light energy may also be particularly characterized in terms of the known effects on light transfer caused by the selected media.  Two or more such media may be utilized so that the emergent light characterized by each different media may be mutually compared, to thereby establish calibration constants for the overall optical capabilities of the optical-response apparatus under calibration.  Thus, in subsequent operation of the calibrated apparatus, during actual tissue examination, the calibration constants so determined may be used to modify nominal tissue-examination data and convert it into intrinsically accurate form which may be directly compared on a meaningful quantified basis to any other similarly calibrated tissue-examination apparatus.

Abstract: ABSTRACT            Heavy oil is upgraded to produce high quality synthetic crude oil, using coal as an adjuvant. The heavy oil is fractionated to recover light distillate fractions (plus diluent if added to the heavy oil to improve its pipeline flowability) and heavy  residuum.  The  residuum  is  combined  with  a  minor proportion of prepared coal having low moisture and ash content, pumped to reaction pressure and preheated to reaction temperature. The coal is solubilized in the oil in a coal solubilization reactor in which a first stage of hydrogenation takes place,  and the resultant solubilized coal/heavy oil residuum mixture is further hydrogenated to provide light distillate raw products and an unconverted coal/heavy oil residue.  The  distillate  products  from  the  heavy  oil fractionation and coal/heavy oil hydrogenation  steps  are hydrotreated to remove undesirable contaminants  (sulphur, nitrogen, oxygen) and improve their stability and quality. The hydrotreated fractions are combined to form a high quality synthetic  crude  oil  (distillate)  product  which can  be processed efficiently by a petroleum refiner to yield high quality transportation fuels. The coal/heavy oil residue is combusted in a fluid bed combustion unit to generate high pressure steam for use within the processing facility, or fed to a hydrocoking unit to yield additional distillate products and low quality coke.

Abstract: ABSTRACT OF THE DISCLOSURE           An intermittently operating watering device has a water reservoir for supplying successive flows of water to a pair of receptacles which are separated from one another by a weir.  The water also flows into an air space where  it  covers  the lower end of an air passage communicating with an air space at the top of the interior of the water reservoir so that, each time evaporation of the water uncovers the lower end of the air passage to allow the inflow of air, water is able to flow out from the water reservoir to the receptacles.  The reservoir is in one of  the receptacles and a plant in the other receptacle is irrigated at successive intervals of time.

Abstract: Abstract:         A parallel data transmission system comprises a cable which is capable of balanced mode transmission but which is driven in an unbalanced mode.  The cable includes a plurality of twisted pairs of individually insulated conductors enclosed by a metallic shield.  The twist lengths are relatively short to cause the pairs to be decoupled sufficiently from one another to allow substantially error-free, parallel transmission over relatively long distances.  Interposed between the core and the shield is a spacing member which has a relatively low dielectric constant.  Receiving facilities are provided for detecting whether the level of transmitted signals is above or below predetermined threshold values and for converting the received signals into one of two or more logic levels.  Advantageously, this system increases substantially the distances over which substantially error-free transmission in an unbalanced mode can be accomplished.

Abstract: EDDY CURRENT TOUCH SENSOR ABSTRACT OF THE DISCLOSURE An eddy current type sensing device for sensing displacement from an eddy current sensor, mounted in a holder, and having a cap actuator mounted for movement towards and away from the sensing face of the sensor.  A spring biases the cap actuator away from the sensing face of the sensor.  The actual target presses against the cap actuator and moves the cap actuator towards the sensing face of the sensor.          The cap actuator, or at least that part of the cap actuator facing the sensor, is made of a material that is suitable for the eddy current sensor and the material is uniform.  The eddy currents are thus induced in the cap actuator, rather than the actual target, so that the displacement readings are not affected by the actual target aspect, configuration, composition or uniformity.  The sensing devices are particularly suitable for use with equipment for fuelling or refuelling a nuclear reactor where the axis of the refuelling nozzle must be aligned with the axis of the fuel channel tube.
