Abstract: ABSTRACT OF THE DISCLOSURE           In order to simplify the construction and to reduce the resistance to flow, and to provide a high inertia in relation to all essential axes, an offshore vessel comprises a pair of parallel under-water bodies, four columns mounted symmetrically thereupon, and a box-like deck structure, interconnecting the upper ends of the columns.  This structure will increase the strength of the vessel so only one horizon-tal, transverse stay is required between each pair of columns. Below each column there is a 360°-turnable shrouded propeller, which together may hold the vessel stationary, with a vertical line of symmetry in a desired position, for instance above a bore-hole.  The box structure has a completely closed bottom and sideplating, and will, in case of need, retain the vessel floating.

Abstract: METHOD AND APPARATUS FOR OPERATING A THERMAL PRINTER        WITH UNIFORM HEAT DISTRIBUTION     ABSTRACT OF THE DISCLOSURE A method and apparatus are provided for controlling a printer of the type having a number of blocks of print heads, each block including print heads preferably of the thermal print type.  Data signals representing the selective energization of the print heads are stored, and these data signals are selectively read out to energize a group of print heads in each block,  sequentially by block.  After one group of print heads in each block is energized, another, different group of print heads in each block is energized, and so on, until all of the print heads have been energized. The print heads in each group are sufficiently spaced from each other to minimize thermal interference due to the energization of an adjacent print head.  Consequently, the temperature of the print heads is distributed uniformly.

Abstract: ABSTRACT OF THE DISCLOSURE      Submerged cavities such as occur in jacketed pilings in offshore structures are grouted by the sequential use of materials with initially decreasing densities, the heaviest of which is lighter than water, followed by the use of conventional grouting materials of greater density. The first material is quick setting and generally water-im-miscible. Water is thus displaced  downwardly out of the cavity by the lighter material. The first material is forced to the bottom of the cavity and allowed to set as a plug to support the conventional grouting materials.

Abstract: ABSTRACT OF THE DISCLOSURE A method for thermally treating pulverulent material, i.e., keeping the material at a certain temperature, the treating temperature, in a desired period of time, in particular sintering, pulverulent material in a cylindrical reaction chamber with an axis slightly inclined to the horizontal after the material has been heated to the treating temperature outside the reaction chamber suspended in a gas. The method is especially applicable for thermally treating materials which tend to become sticky at the treating temperature, in particular for sintering pulverulent materials, i.e., agglomerating these by heating without complete melting. However, the method is also useful for general thermal treatment where sintering is not intended, e.g., for burning Bauxite, Mesa and phosphate bearing ores. An example of a sintering process to which the invention is particularly applicable is the manufacturing of cement clinker where the pulverulent material to be sintered is hot calcined cement raw meal. An apparatus for practicing the method of the present invention is also disclosed.

Abstract: Abstract of the Disclosure In the inspection of generally round glass con-tainers where the containers are indexed into the gauging stations or positions by the movement of a starwheel mech-anism, the containers are held in a generally upright at-titude with their bottoms engaging a pair of spaced rollers extending through a slide plate at the gauging station.          Each roller is biased in an upward direction against the container bottom.  The containers are rotated, in station, by engagement of the sidewall thereof by a rotating wheel mounted on an axis that is somewhat out-of-vertical to aid in holding the container down against the rollers and slide plate.  The gauging rollers each have their vertical move-ments to drive the core of a separate differential trans-former.  The output of the transformers are amplified, algebraically summed and fed to a discriminator.  The track-ing of the rollers is such that the output signals from the discriminator are a reflection of the relative positions of the rollers and the output is fed to a reject mechanism or indicator when a predetermined difference indicates that a "leaner" container is being gauged.

Abstract: ABSTRACT         A cumene oxidation product containing cumene hydroperoxide (CHP) and dimethylphenylcarbinol (DMPC) is decomposed with acid catalyst in a first step at mild temperatures that lowers the CHP concentration to about 0.5-5% and converts most of the DMPC to dicumylperoxide (DCP).  In a second step at mild temperatures the CHP concentration is lowered below 0.4%. In a third step the DCP is decomposed at a higher temperature for a short time to alpha-methylstyrene (AMS), Phenol and acetone, with any remianing DMPC also converted to AMS. The DCP concentration is monitored during the third step, and the reaction is stopped by cooling when about 0.5-5% of the DCP remains undecomposed so as to maximize AMS yield.

Abstract: ABSTRACT An air conditioning system and method wherein a central pumping sys-tem circulates a heat-exchange liquid (which is water or a glycol solution or other solution called "water") through heating and cooling paths of a refrigeration system and then to and from air-treating units.  The fans or blowers of the air-treating units are positioned upstream of the air cooling and heating coils so that the fan heat and pump heat are discharged through the fluid cooler system during cooling load operation, and all of that heat is available for delivery to the air treating units during heating-load operation.  The quantity of outside (fresh) air is selected and controlled so that adequate ventilation is provided, and during cold weather so that multi-storey buildings may be provided with adequate pres-surization to overcome an objectionable inflow of cold air at ground floor levels at entrances and exits.  In the embodiments shown, such additional air is discharged through the fluid cooler to carry away heat during cooling load operation.  One embodiment includes a separate line for neutral water to each air treating unit.  The neutral water is mixed with either the hot water or the cold water supplied to each air-treating unit for temperature control as distinguished from the standard three-pipe system wherein hot and cold water are mixed to provide temperature control.  Another embodi-ment is a four pipe system having separate supply and return lines for both hot water and cold water.  The systems may be designed and operated to util-ize the heat pump principle to raise the temperature of the heat-exchange liquid flowing to the fluid cooler above the generally accepted levels. That makes it possible to discharge the heat with a substantially smaller stream of the heat-exchange liquid flowing to the fluid cooler, and thereby reduce the sizes of pumps, motors, piping, and other components of the sys-tem.  In turn, that:  (a) reduces the power consumption so that a smaller amount of fan and pump heat is produced; (b) improves the efficiency of the system; and (c) reduces the amount of heat which must be discharged through the fluid cooler under cooling-load conditions.

Abstract: ABSTRACT:          "Apparatus for optically scanning a disc-shaped record carrier."           An apparatus for optically reading a disc-shaped record carrier, which apparatus comprises a radial tracking control system which employs a radial error signal obtained by comparing two signals supplied by two radially adjacent detectors. In order to stabilize the loop gain of the control loop thus formed at a constant value, a measuring signal of predetermined frequency is injected into the control loop and the response of the control loop to said injected signalis compared with the injected signal, which comparison results in a control signal for a controllable amplifier circuit. Suitably, said comparison is a phase comparison. The injected mea-suring signal causes the scanning beam to oscillate relative to the track to be followed. By measuring the correlation between said oscillation signal and the amplitude of the information signal being read, a signal can be obtained which is a measure of deviations, not caused by tracking errors, between the signals supplied by the two detectors and which may be used for correction purposes.
