Patent CA-1264558-C (CA)
IPC: B24B49/16
Filed: 1984-06-29
Granted: 1990-01-23
Abstract: Apparatus for improving tire uniformity includes contra-rotating grinding wheels (32, 34) for removing tire material from the upper and lower shoulder portions of the tire (16). The grinders are moved on an assembly (18) into grinding engagement with the tire along a path that is defined by a radius of the tire to ensure that both grinding wheels at each shoulder of the tire make simultaneous contact with the tire. The amount and extend of grinding accomplished by the contra-rotating grinders is controlled by a grind control circuit. The grind control circuit measures the no-load current level of the grinder motor and compares the no-load current level with the current level when the grinder motors are under load. When the grinder current under load is above a predetermined maximum load current, the control circuit will signal the grinders to retract from engagement with the tire until the load current drops below the predetermined maximum level. When the motor load current is below the minimum operating range level, the grinders are signalled to advance into engagement with the tire until the load current reaches the predetermined minimum level. This operations is repeated in cyclic fashion until the tire has been ground a sufficient amount to bring it within an acceptable correction range. An alarm circuit which cooperates with the grind control circuit assures that once a grinding operation is begun it will have a predetermined minimum time duration. The alarm circuit also detects whether one of the shoulder grinders takes too long to engage the tire after the other shoulder grinder has made such engagement. The alarm circuit will stop the grinding operation if too long a period of time has elapsed and if there are other malfunctions of the grinders.

Abstract: Novel vectors are disclosed for expressing and secreting heterologous polypeptides from filamentous fungi. Such vectors are used in novel processes to express and secrete such heterologous polypeptides.  The vectors used for transforming a filamentous fungus to express and secrete a heterologous polypeptide include a DNA sequence encoding a heterologous polypeptide and a DNA sequence encoding a signal sequence which is functional in a secretory system in a given filamentous fungus and which is operably linked to the sequence encoding the heterologous polypeptide. Such signal sequences may be the signal sequence normally associated with the heterologous polypeptides or may be derived from other sources.   The vector may also contain DNA sequences encoding a promoter sequence which is functionally recognized by the filamentous fungus and which is operably linked to the DNA sequence encoding the signal sequence.   Preferably functional polyadenylation sequences are operably linked to the 3' terminus of the DNA sequence encoding the heterologous polypeptides. Each of the above described vectors are used in novel processes to transform a filamentous fungus wherein the DNA  sequences encoding the signal sequence and heterologous polypeptide are expressed. The thus synthesized polypeptide is thereafter secreted from the filamentous fungus.

Abstract: ABSTRACT                 This invention relates to apparatus for forming a plurality of supply rolls consisting of respective wound strips formed from a wide web by slit-ting, comprising guide rollers for guiding the web and strips, cutters for slitting the web, and winding means having winding cores for winding the strips. A pair of winding means are provided on each of the two sides of a central guide roller, which guides the strip along divergent paths, the winding means of each pair have parallel axes of rotation and are mounted in a rotary frame, which is rotatably mounted in the main frame of the machine and comprises two reversing discs, which are adapted to rotate said rotatable frame and are provided with rotary drives. The winding means of each pair are slidably mounted in tracks of the revers-ing discs for a movement of the winding cores parallel to themselves along a diameter of the reversing discs and are adapted to be displaced along said tracks by drives. Each winding means of each pair is movable from an end portion of the tracks to a position in which said winding means is adjacent to the center of the rotary frame. Each winding means which has been moved to the inner end of the approximately horizontal track is adapted to cooperate with a cross cutter, which is pivoted in the main frame of the machine, and with an associated pressure-applying roller. Each of said cross cutter and the associated pressure-applying roller are operable to sever the strip and to urge the succeeding strips at its leading end onto a glue-coated tube or the like, which constitute a core for a supply roll to be wound.

Abstract: SPECIMEN COLLECTION AND SAMPLING CONTAINER          ABSTRACT The invention provides a specimen collection and sampling device, particularly useful for urine samples, for collecting a liquid sample and segregating an aliquot of the sample away from contact with the remaining portion of the sample. This segregation is accomplished as the lid is closed on the container.  In one embodiment, the aliquot sample is transferred to an evacuated tube held within the container.  In another embodiment, the aliquot is held within a sample chamber that is built into the container.  In a preferred embodiment, the aliquot is mixed with a treating agent to maintain the microbiological integrity of the aliquot, or to provide an appropriate reagent or buffer for drug analysis.
