Abstract: Abstract In a disk type mass storage facility for data processing systems, a disk format which reduces access time and is compatable with an improved method of handling defective segments of medium.  The format has three layers.  A first, physical layer comprises the bytes, sectors and collections of sectors, as well as error detection and correction codes.  A second, logical layer is used to address the physical layer and to collect together sectors to form a multiplicity of separately addressable spaces, with each space having a distinct functional utility.  At a third, functional layer the use of data fields in each space is specified. This layer governs the handling of bad blocks if required, and the use of certain format information.    At the physical layer, bits are collected into sectors, sectors are collected into tracks, tracks are collected into groups, and groups are collected into cylinders.  These are logically, rather than physically, defined collections.  A group is set of tracks wherein individual tracks in a group can be selected in the inter-sector rotation time.  At the logical layer, the disk is divided into three main areas, each separately addressable.    Minimization of access time latencies is obtained by proper selection of logical addressing - i.e., by selecting the number of sectors/track, tracks/group and group/cylinder-to take advantage of access characteristics.    Various drive parameters are stored in the disk and are supplied to its controller on command, permitting the controller to adapt thereto.  These include the starting address for each of the various areas, or spaces, of the disk, and for example, its transfer rate, logical addressing structure, etc.

Abstract: VACUUM FORMABLE WATER COOLING TOWER FILM FILL SHEET WITH INTEGRAL SPACERS            Abstract of the Disclosure A vacuum formable film fill sheet for cross-flow water cooling towers is disclosed having a repeat-ing chevron pattern defining a series of zig-zag, serpentine, spaced ridges on opposed faces of the sheet with the ridges on one face of the sheet defining the grooves on the opposite face thereof and vice versa. The formed sheets are located in upright, horizontally spaced relationship between  the  overlying hot water distribution basin of the tower and the cold water basin thereof for generally horizontal flow of air past films of water flowing downwardly over the fill sheets. The angularity of the straight ridge sections of the chevron pattern with respect to one another, the verti-cal height of each repeat pattern,  the transverse angularity of the ridges and the spacing between adja-cent sheets has been unexpectedly found to provide significantly improved results as compared with prior chevron pattern fill sheets.   A series of integral, spaced,  transversely W-shaped  spacers  projecting  in opposite  directions  from  each  of  the  sheets  have notches in the intermediate V wall portions which complementally receive the outer foot portions of each spacer to maintain adjacent sheets in required hori-zontally spaced relationship.  The spacers are inclined at angles which provide minimum interference with air flow and are oppositely inclined for required comple-mental interfit with the spacer of an adjacent fill sheet.

Abstract: Abstract A flexible current feeding post for interconnecting electrically and mechanically circuits on one substrate to circuits on a parallel substrate is described.  The post has two conducting parts, for example, a solid cylinder or a disk of metal co-axially connected by a bellows.  The axial and radial flexibility of the bellows provides dimensional flexibility allowing the post to be connected between the substrate without undesirable distortion of the substrates.  As a result, the voltage drop at the contact points between the feeding post and the counter portion of the circuit formed on the substrates is substantially reduced, increasing considerably the reliability of the apparatus and reducing the assembly cost of the substrates.  A flexible by-pass means is also proposed to increase the current capacity of the feeding post.

Abstract: LIQUID PRODUCT DISPENSING PACKAGE WITH SELF DRAINING FEATURE EMPLOYING DRIP CONCENTRATOR                   DELMAR RAY MUCKENFUHS ROBERT HENRY VAN CONEY                         ABSTRACT           A liquid dispensing package is described which is adapted to dispense liquids without mess. The package preferably incorporates a measuring cup which is also the closure for the package. The package of the present invention includes a container for storing the liquid product and a collar sealingly secured to a dispensing orifice on the container. The collar has an extended pouring spout and a transverse drain back partition with a drain hole to collect and return residual liquid to the container. A drip concentrating member originates in the lowermost surface of said drain back partition about the periphery of the drain hole and extends generally downwardly from the drain back partition toward the pouring spout to form a drip concentrating point in the interior of the container. Any liquid spilled on the exterior of the drain back partition or draining back onto the exterior of the drain back partition from the cap after a dispensing cycle is completed coalesces at the drip concentrating point. Coalescence of liquid at a single point causes a larger and larger droplet to form at the point. When the weight of the droplet finally exceeds the surface tension forces exerted by the liquid on the drip concentrating point, the droplet falls back into the container, and the process is restarted until the bulk of the liquid has been redeposited into the container. Because the drip concentrating point is at an elevation below the exterior surface of the drain back partition and the wall forming the drip concentrator is generally oriented toward the pouring spout, any residual liquid falling from the drip concentrating point during the dispensing cycle will fall harmlessly within the container, into the liquid product steam being discharged or onto the interior product contacting surface of the drain back partition.

Abstract: ABSTRACT OF THE DISCLOSURE     A multi-function industrial robot employs an servo motor to select one tool for use from among a plurality of tools mounted on a turret, the base of which is fixed to an end of a vertical spindle and supports a turret shaft that lies at an angle of 45° with respect to the spindle.  The turret head on which the tools are mounted is fixed to one end of the turret shaft and it and the tools are configured so that one active tool will be coaxial with the spindle, and a bevel gear mounted at the end of the turret shaft opposite the turret head engages a bevel gear mounted on the robot frame.  The spindle can be raised and lowered such that at its uppermost position the two bevel gears engage, and a mechanism that normally prevents rotation of the turret shaft is released so that as the spindle turns the turret-mounted bevel gear revolves about the stationary bevel gear and drives the turret shaft and the turret head for rotation.  By turning the spindle through a specific angle, a specific tool can be moved into alignment with the spindle.  When the spindle is lowered, the bevel gears disengage and the locking mechanism prevents further rotation of the turret shaft and rotation of the spindle is directly transmitted to rotate the selected tool.
