Title: Roll cleaning apparatus
Inventor: LAPPALAINEN TEUVO
IPC: B05C1/08
Filed: 1994-11-17
Abstract: [57] Abstract A method and an apparatus is described herein for cleaning the surface of a backing roll in a coater or a calender roll. The roll (1) is cleaned by spraying water on it and then scraping the water away from the surface of the roll (1) by means of a doctor blade (4). According to the invention, splashing of the water accumulating in front of the doctor blade (4) is prevented by means of a rubber sheet (5) extending down close to the tip of the blade (4), or alternatively, using a guide blade mounted in front of the doctor blade (4). The rubber sheet (5) preceding the doctor blade (4) isolates the water pond formed in front of the doctor blade from the surface of the roll (1), whereby the rotational movement of the roll (1) cannot induce turbulence and splashes.            (Fig. 2)

The seat flap is pivotally movable between a stored position parallel to the second face and an operative position substantially perpendicular to the second face.   The seat flap has opposed sides.   A pair of flap supports are secured to the mat-like body.  Each flap support is secured to one of the opposed sides of the seat flap.  The flap supports provide support to the seat flap when it is in the operative position.  Straps are attached to the opposed sides of the flexible mat-like body adjacent one of the first end and the second end.  The straps terminate in compatible fasteners that are capable of coupling.  The straps provide means for attaching the flexible mat-like body to a person's waist when the flexible mat-like body is formed into a roll.

Title: Method of Improving Oil and Gas Well Productivity
Inventor: LOREE DWIGHT N
IPC: C09K8/594
Filed: 1995-01-25
Abstract: A method  of  improving  oil  or  gas  well productivity from a well penetrating a formation in an oil  or  gas  reservoir,  by  injecting  a stream  of liquified drive fluid into the well ahead of a load fluid to establish a miscible bank of drive fluid in the well.  While injecting the stream of liquified drive fluid into the well, a load fluid in which the liquified drive fluid is miscible is injected into the well mixed with the liquified drive fluid. The ratio of liquified drive fluid to load fluid is initially at a level sufficient to form a miscible bank of drive fluid in the gaseous state ahead of the load fluid in the well. Subsequently, the ratio of liquified drive fluid to load fluid injected into the well is reduced.

Inventor: GOLDSTEIN VLADIMIR
IPC: F25C5/20
Filed: 1995-02-27
Abstract: A method and system for delivering aqueous ice slurry is disclosed. In one embodiment, the ice slurry delivery system includes a storage tank having an inlet to receive an aqueous ice slurry from an ice generating unit. A circulation loop is connected to the storage tank. Ice slurry held in the storage tank flows through the circulation loop generally continuously at a first rate. Valved discharge points are located along the circulation loop at spaced locations and are operable to re-direct some of the ice slurry flowing through the circulation loop to deliver ice slurry for end use upon demand. The rate of flow of ice slurry through the discharge points is less than the first rate evenwhen all of the discharge points are re-directing ice slurry for end use.

Title: Drill bit having stability enhancing cutting structure
Inventor: KEITH CARL W
IPC: E21B10/54
Filed: 1995-09-28
Abstract: A fixed cutter drill bit includes a cutting structure having radially-spaced sets of cutter elements.  The cutter element sets preferably overlap in rotated profile and include at least one low profile cutter element and at least two high profile elements.  The low profile element is mounted so as to have a relatively low exposure height.  The high profile elements are mounted at exposure heights that are greater than the exposure  height of the low profile element, and are radially spaced from the low profile element on the bit face.  The high profile elements may be mounted at the same radial position but at differing exposure heights, or may be mounted at the same exposure heights but at different radial positions relative to the bit axis.  Providing this arrangement of low and high profile cutter elements tends to increase the bit's ability to resist vibration and provides an aggressive cutting structure, even after significant wear has occurred.
