Patent CA-2154285-A1 (CA)
Title: Improved rotary roller reamer
Inventor: KENNEDY JOHN FRANCIS
IPC: E21B10/22
Filed: 1994-11-10
Abstract: A rotary roller reamer (10) for a borehole has several rollers (11). Each roller (11) rotates about a fixed spindle (13) held at its ends in wedge blocks (14). The spindle (13) has two central passages (19), one at each end.  At one end, passage (19) contains a freely slidable piston (21), which is subject to external pressure via a breather aperture (22). The other end passage (19) is blocked by a pressure plug (27) which, when removed, permits injection of grease through passages which include the bearing surfaces of the roller (11) and spindle (13). External pressure is applied to the grease through piston (21), so that there is little or no pressure differential to otherwise force mud into the bearing.

Inventor: MCFALL RONALD RAY
IPC: A61F13/15
Filed: 1994-06-08
Abstract: A method is disclosed for attaching an elastomeric film laminate web to the longitudinal side edges of an absorbent article such as a sanitary napkin. The method involves using a system of different adhesive applying mechanisms (that is, glue guns) and different applications of adhesive in a spiral pattern to provide precise control over the pattern and the amount of adhesive applied to bond the web of material to the absorbent article. The method comprises applying a narrow spiral of adhesive to a first portion of the width of the web that is adjacent a first edge of the web; bringing the first portion of the web into contact with a first face of the sanitary napkin so that the remaining portion of the web extends outward beyond the edge of the sanitary napkin; applying a second narrow spiral of adhesive to a second portion of the width of the web adjacent the second edge of the same; folding the second portion of the width of the web onto the second face of the sanitary napkin to wrap the edge of the sanitary napkin; and securing the wrapped web to the sanitary napkin.

Filed: 1996-03-20
Abstract: A variety of methods, apparatus, and data structures for managing transient and persistent distributed objects are disclosed. Objects for use as object references are described, both for transient and persistant objects. In one aspect of the invention, a data structure that is intented for use as an object reference for a transient object is disclosed having a set of endpoint addresses, an incarnation number, and an object key. These elements serve to uniquely identify and locate the transient object. In another aspect of the invention, an object that is intended for use as an object reference for a persistent object is disclosed having a host computer name, a locator identification, an object key, and a subobject identifier. The first three elements serve as an indirection to the pensistent object and the third element is for use by the persistent object. These data structures enable a distributed object operating environment which integrates both transient and persistent objects. A variety of methods utilizing one or more of the elements of the abovementioned object references to provide a system resource efficient interaction between a client requesting service from a server object. One particular method selects the fastest transport mode between the client and the server object. Another specific method teaches reading addressing information directly from local cache memory. If the addressing information is not available in cache memory, the information is first found and then stored in cache memory thereby perpetuating the efficiency of the invention.

Abstract: A turn coordination inhibit system (150) inhibits a rotary winged aircraft control system from operating in an automatic turn coordination mode when a pilot desired to perform a sideslip maneuver, e.g., a flat turn. When automatic turn coordination is not engaged (132, 212, 215), e.g., the aircraft is not in a coordinated turn, and either aircraft bank angle (119) exceeds an inhibit threshold magnitude (210) or a pilot yaw command provided by a pilot sidearm controller (155) exceeds a minimum threshold value (243), e.g., the sidearm controller is out of detent in the yaw axis, automatic turn coordination is inhibited (152). Automatic turn coordination remains inhibited until both aircraft bank angle falls below a reset threshold magnitude (230) and the sidearm controller is back in the detent position for the yaw axis (243).

Title: Lifting mechanism for a deck system
Inventor: SMIDLER FRANCIS S
IPC: B60P3/07
Filed: 1996-11-29
Abstract: A trailer for hauling cargo, such as general freight, automobiles, small trucks and the like, has a deck element therein.  The deck element is capable of being raised or lowered by a lifting assembly to a variety of positions within the trailer and can be secured to side walls of the trailer by cam bracket members.  A guide assembly is provided to prevent forward and rearward movement of the deck element during transportation of the trailer.  The trailer can be tilted backwards until a back end of the trailer contacts the ground so that cargo can be easily loaded into the trailer.  Cargo can be loaded onto the deck element and underneath the deck element on the floor of the trailer. The lifting assembly is substantially horizontally arranged along the top of the trailer so that when automobiles are loaded onto the deck element and the deck element is raised, the lifting assembly does not interfere with the space occupied by the automobiles.

Title: Gas flow control valve for a continuous flow water heater
Inventor: SCHULZE KLAUS
IPC: F23N1/08
Filed: 1995-06-08
Abstract: 1. Fitting, especially for a continuous flow water heater. 2.1. The submitted invention takes as its basis the problem of developing a fitting of the named type by which the formation of calcareous deposits on the rod protruding from the water control housing is lessened and the influence of such calcareous deposits on the controller action is completely eliminated. 2.2. The problem is solved in that within water control housing (2), the control motion of membrane (24) is transmitted to a lever (3) whose centre of rotation forms a shaft (4), rigidly connected to this lever (3) and whose pivot is sealed, leading to the exterior of water control housing (2). At the same time, shaft (4) is also the centre of rotation for a second lever (5) which is likewise rigidly connected to it. Thus the stroke motion of the first lever (3) is transmitted to the exterior via shaft (4) as a rotary motion and subsequently the rotary motion of shaft (4) is re-converted, by means of second lever (5), into a stroke motion to control the gas outlet. 2.3 The fitting serves to control gas flow depending on water flow especially for continuous flow water heaters. 3. Fig. 1.
