Abstract: SINGLE-PIECE INJECTION MOLDED RACK    Abstract of the Invention A single-piece, injection molded rack for holding test tubes or similar articles and a mold for producing the same. In a preferred three-tiered form, the intermediate tier is a lattice defined by the intersection of two superposed sets of parallel bars. These two sets of bars are formed by two pairs of correspondingly channeled slides that cooperatively engage to form a portion of the mold cavity corresponding to the lattice. The channels in each set of slides are aligned with the path of movement of the slides to permit their sliding, uniaxial movement relative to the molded bars. To further enable this sliding movement between mold segments and the molded rack, the connecting supports between the top tier and the intermediate tier are provided on the sides of the rack, while the connecting supports between the intermediate tier and the bottom tier are provided on the front and rear of the rack. With this arrangement, the slides that form the lattice of the intermediate tier are free to slide, as well, along the inner surfaces of the supports, which they also help to form.

Abstract: Abstract The present invention relates to a flattened flexible con-tainer made ready for filling with bulk material, and method and means for making a container comprising a liner of im-pervious sheet in an outer container of strong load-bearing material. The liner and the outer container are folded longi-tudinally in the same way such that the liner is kept in position by having its folds or gussets everywhere placed in the corresponding folds or gussets of the outer container.          Both the liner and the outer container may have a longi-tudinal gusset on each side which can have a width of up to 1/8 of the container's circumference. The manufacture can be carried out in an apparatus (8) in form of a box which is open in both ends and can be folded together. Its side walls consist of longitudinal parts (7) which are connected to each other and the roof (4) and bottom (5) of the apparatus (8) by means of pliable connecting means (6). The container accord-ing to the invention can be filled with bulk material without prior inflation at the filling site.

Abstract: METHOD FOR THE PREPARATION OF COKE                 ABSTRACT OF THE DISCLOSURE     In a method of making coke in coke-ovens of a coke oven battery, the coke temperature is measured using at least one infra-red sensor after pushing of the coke from a coke-oven and before quenching of the coke.  A value corresponding to the difference between measured value of the coke temperature and a predetermined reference value is determined for each of a plurality of coke loads pushed from a series of coke-ovens.  The mean of said difference values is determined and the combustion gas supply to at least a plurality of coke-ovens of the battery is adjusted in dependence on said mean of the difference values.          In this way, better control of the temperature of the coke at the end of the coking time can be achieved, with less deviation of the coke temperature from the reference value.

Abstract: ABSTRACT           A machine for automatically roughing the cement margin of a footwear upper assembly. The machine includes means for supporting the footwear upper assembly by a mechanism  capable  of  applying  to  the  upper  assembly rocking movement, translational movement and rotational movement.  A roughing tool is provided, as well as means for  applying  a  combination  movement  to  the  upper assembly.  Simultaneously, roughing is effected along the shoe margin by the roughing tool.   The combination of movements serves continuously to present a new roughing surface to the roughing tool in the course of roughing, resulting  in  uniformity  of  roughing.   The  rotational movement serves to cause the roughing tool to track the cement margin with a determined orientation therebetween as the cement margin moves past the roughing portion of the roughing tool.

Abstract: ABSTRACT OF THE DISCLOSURE            The  problem  of cracking in scantlings  of  aluminium  or aluminium  alloy  engine  blocks by direct  and  torsional forces  applied  thereto by a crankshaft is  mitigated  by casting,  into the scantlings, reinforcements of a ferrous material.   Each   reinforcement includes threaded  bosses for  receiving the bolts which hold an associated cap onto the scantling and also flat elongate members which  extend into  the scantling.   Since the threads are of a  ferrous material, they are more   resistant to damage than similar threads  of aluminium or aluminium alloy and the  elongate membrs  spread  the loading throughout the  scantling,  so reducing  the  tendency  of  these  loads  to  crack   the scantling.   This  technique can be of particular  benefit where  an  engine    is  being modified  in  a  way which produces increased stresses;   for example where a  petrol engine is being converted for use as a diesel engine.

A biological particle stained with fluorescent dyes is excited by a laser.  A flourescence detector detects the fluorescence.  The particle scatters light and a gate signal is generated and delayed until the biological particle reaches the next laser.  The delayed signal turns on this next laser which excites a different stained component of the same biological particle.

A surface compression unit may be provided between the inner and outer cylinders which is operable to supply a pressure to compensate for the loss of overburden in downhole applications.  The surface compression unit may also apply a rotating shear force to smooth the soil surface so that the pressure applied by the unit is uniform.

Abstract: ABSTRACT     The invention provides processes and apparatus for the controlled addition of conditioning (polymer) material to sewage sludge to improve its dewaterability.  These materials are expensive and overdosage is to be avoided, while underdosage causes difficulty in sludge handling.  The principal problem has been the absence of a system capable of continuous determination of proper dosage.  It has been found that shear stress tests with a viscometer result in characteristics that exhibit a unique peak when dosage is adequate or above.  A control system controlling the rate of pumping of the polymer to mix with the sludge is operative by measuring the shear stress and increasing the dosage in the absence of a peak.  Upon detection of a peak the rate of decrease after the peak is also measured and used to resolve the potential ambiguity of whether dosage should be increased, decreased or remain steady.  The viscometer can be of variable shear rate type, but it is found that the control system can also employ a simple fixed rate viscometer, the shear stress then being evaluated for peak and slope over a predetermined time interval.  Specific control strategies are disclosed that will reduce the rate of change of dosage as the optimum is approached to avoid overshoot, and also to increase the time interval between tests to avoid unnecessary operation.

Abstract: ABSTRACT OF THE DISCLOSURE          A bearing assembly has a half block bushing for supporting a roller journal thereon, with outer walls having an angular shape which fits into a correspondingly shaped bushing cradle mounted to a mounting bracket.  The half block form of the bushing permits convenient manufacture and disassembly of the bearing for replacement of parts, and has longer and more stable wear characteristics.  The outer walls of the bushing are preferably trapezoidal to prevent rotational movement of the bushing relative to the cradle and mounting brackete, and to permit easy removal of the bushing during replacement.  A spring wire clip lock is used to retain the bushing and cradle in position relative to the mounting bracket by spring pressure.
