  • Patent number: 4841733
    Abstract: A temperature and humidity control system for natatoriums. The system provides a constant volume of air circulation which is used to control temperature and humidity in the natatorium while inhibiting the accumulation of moisture on the surfaces defining the natatorium. Usually, ambient air is introduced into the system and moisture latent air discharged from the system under controlled conditions. When the humidity of the ambient air is too great the system operates in a self-contained cycle. Return air from the natatorium flowing through the system is treated to maximize its relative humidity. Subsequently, it flows across a cooling coil. This cooled air flows through a heat exchange module where it is placed in exchange relationship with the air being drawn from the natatorium. It cools the air drawn from the natatorium to maximize its relative humidity and this air in turn flows across the refrigeration coil removing substantial quantities of moisture.

  • Patent number: 4835711
    Abstract: A robot system having various work stations and control means which allows recognition of the identity, position and geometry of a plurality of the work stations and assures movement of a robot manipulator among the work stations without its colliding with them even if new work stations are substituted for original work stations or if work stations of substantially different geometry are moved from one position to another. In a particularly advantageous aspect of the invention, the control means of the robot system derives its operating and clearing procedures from information fed to it from intelligence, or code, that is specifically associated with each of the work stations. This arrangement allows rapid set up of a laboratory robot to perform any of a large number of combinations of events.

  • Patent number: 4828300
    Abstract: A split retaining ring is disclosed for detachably interconnecting a pair of axially aligned circular rims. The ring has ends and a circular side wall with front and rear flanges protruding radially inwardly therefrom. The ring ends are resiliently separable to accommodate installation and removal of the ring onto and off of the rims, and are resiliently closeable to confine the rims radially within the ring side wall and axially between its flanges. The rear flange has a radially tapered configuraiton with oppositely disposed minimum radial dimensions arranged to minimize the extent of separation required between the ring ends during installation and removal.

  • Patent number: 4828433
    Abstract: A roof support employs an hydraulic piston and cylinder unit as an adjustment device between the goaf shield and the roof-engaging structure. The cylinder unit is mounted to the shield with the aid of a bearing body defining a cup receiving a spherical end of the cylinder. The body also has recesses accessible via offset openings in which journals projecting from the cylinder are located. Locking pieces detachably fitted to the shield block the openings to retain the journals therein yet permit easy assembly and dismantling of the unit.

  • Patent number: 4826071
    Abstract: The invention broadly comprises forming a weld preparation groove in the surface of a cylindrical roller, said groove being parallel to the longtitudinal axis of the roller. The groove is filled with a weld material. Subsequently, the outer surface of the cylinder is welded with a compatible welding material to coat the cylinder surface. The weld materials both for the groove and the surface are compatible such that when the surface is welded, the weld material in the groove is recast to form a homogeneous grain structure with the surface weld. The slot is then formed and the surfaces of the facing walls of the slot, the slot edges and the roller surface are uniformly coated.

  • Patent number: 4821505
    Abstract: A method and apparatus of forming a fibre assembly to be spun to form a yarn. The separated fibres are entrained in an air stream (61) and delivered in a tangential direction into a converging annular passage (64). The fibres are straightened in their travel through the passage (64) and issue as a peripheral curtain into a fibre collection zone (67), where the fibres merge to form a coaxial fiber assembly with the passage (64), and are shed from the airstream which is diverted to be withdrawn rearwardly from the fibre collection zone (67). The cohered fibre assembly is withdrawn forwardly from the collection zone to be spun to form a yarn.
