  • Patent number: 5152026
    Abstract: A siphon transfer, cooling tower sump water cleaning device, which has a cleaning nozzle attachment (20) connected to an extension tube (32) and a collecting chamber (44). The collecting chamber has a drain hose (52) threadably attached on the end and the entire device is placed under the sump water (38) of a cooling tower (34) for priming. The hose is placed below the water level and the nozzle is scrubbed against the bottom of the cooling tower sump (36). As debris and foreign matter is dislodged and is in solution with the water siphon action takes place drawing the mixture into the tube (32). At the end of the tube the inside diameter increases slightly in the collecting chamber and abruptly, yet smoothly, increases the velocity pressure in an elipsoidal shaped converging nozzle (50) where the increased velocity draws the debris through the remaining hose (52).

  • Patent number: 5152027
    Abstract: A surface sweeper may include a first pulley driven by the motor, a second pulley on a drive shaft for driving the drive wheel, a third pulley for driving the main brush, and a drive belt interconnecting the first and second pulleys which can be selectively tightened by a clutch for driving the drive wheel. Preferably the drive belt has inherent stiffness whereby it spontaneously loosens unless held in its tightened condition by the clutch. The driveshaft advantageously has two parts separated by a gap, for permitting the drive belt to be placed around the driveshaft without removing the driveshaft from its mount. The two parts may be connected by a sleeve which is biased by a spring into position for drivingly engaging the two parts, and which is slidable out of said position for revealing the gap. The main brush may have structures at its two ends that are similar to each other, for being reversibly mountable in first and second brush bearings.

  • Patent number: 5152056
    Abstract: New standard industrial grade solder is first applied to leads of a tape automated bonding (TAB) component of a printed circuit board (PCB) to be replaced, which was previously bonded using standard industrial grade solder. The new and old solder are melted at the same time. The TAB component is removed without removing all the melted new solder. After applying flux to the solder pads, a replacement TAB component is placed onto the TAB component site. Heat and pressure are applied to leads of the replacement TAB component at the same time while the replacement TAB component is being placed onto the TAB component site. Pressure is maintained until the leads and the remaining new solder have cooled below the solder's melting temperature. As a result, the replacement TAB component is connected to the PCB replacing the removed TAB component with reduced number of steps and cycle time for the steps, thereby reducing opportunities to damage the PCB.

  • Patent number: 5152064
    Abstract: The apparatus comprises a chilling implement and a shaving implement. The chilling implement comprises a body with a roller at each end and containing a supply of shaving gel which is dispensed onto one of the rollers. The shaving implement comprises a drive unit and a plurality of cutting edges arranged in a flat plane when at rest. The edges can be deflected out of the plane linearly and perpendicularly to the plane or rockably about axes parallel to the plane and perpendicular to the cutting edges. The apparatus is spring loaded to return the edges to the plane. In refined embodiments the assemblies holding the cutting edges are pivotally attached to allow each assembly to also rock on an axis parallel to the cutting edges and the cutting edge assemblies are springably interconnected so that the plane of the cutting edges can be flat or twisted in either direction about an axis parallel to the plane. The shaving implement also comprises a roller with its axis parallel to the at-rest cutting edges.

  • Patent number: 5152065
    Abstract: The improved tool head of the invention is comprised of two separable members, namely, a main body and a removable section. Each member has an interior channel therein. In use, the two separable members mate to define the tool head while the channels of each member align to cooperatively define a cavity within the tool head. A tool handle is retained within the cavity. Replacement of the tool handle is executed by separating the removable section from the main body, thereby allowing removal of the handle from the aligned channels which define the cavity. The two members of the tool head are joined by bolts or screws such that one end of the tool handle is captured therebetween, within the cavity. Preferably, one or both channels provide teeth, ridges or similar protrusions which will grip the captured handle end to ensure that the handle is secured within the tool head.
