Abstract: A book binding apparatus and method secures pages of a document in a U-shaped channel. The apparatus (20) automatically adjusts its binding jaws (42a, 42b) the current size of the channel (86) prior to the binding force being applied to the channel. Operating forces generated by the apparatus in deforming the channel are limited by generating small amounts of deformation in the channel for each pull of an operating handle (22) to completely secure the pages into the channel. A debinding apparatus (30) and method, using the same operating mechanism as the binding apparatus, debinds the pages from the channel.

Abstract: A mold for molding thermoplastic parts having a plurality of pinholes wherein at least one of the mold cavities has a number of projections in the form of three-dimensional tapering shapes, for example, cones, which extend to a point near to but spaced from the confronting surface of the other mold half cavity. The taper of the angle of the projection and spacing between the apices of the projection and the surface of the other mold half are selected so that molten thermoplastic freezes before it covers the apices of the projections during the molding process to thereby form pinholes in the resulting plastic part. A method for molding plastic parts with pinholes with the use of the mold cavity with multiple projections is also disclosed.

Title: Wellbore sand control method
Inventor: JONASSON RALPH G
IPC: E21B33/138
Filed: 1996-07-08
Granted: 2001-10-02
Abstract: A slug of solution, comprising a linear polymer such as polysulfone, polyethylene terephthalate or polyimide dissolved in a "good" solvent, such as morpholine, m-cresol or dimethylsulfoxide, respectively is emplaced in the near- wellbore region of an unconsolidated sand reservoir. A second slug comprising a poor solvent for the polymer, such as water or water + 2-methanol is pumped into the region to contact the first slug. The linear polymer is precipitated and forms a three-dimensional network of interconnected strands extending through the fluid flow channels between the sand grains. The network functions to consolidate the sand without significantly damaging permeability.

Abstract: A key cutting machine for cutting keys by code has a vise jaw for securely holding a key with a groove of the key aligned with respect to the vise jaw and with at least one of a tip of the key and a shoulder of the key positioned at a predetermined position with respect to the vise jaw, a key cutter, a position detector for detecting a blank edge of the key held by the vise jaw, a movement system for moving the key cutter and the vise jaw relative to one another to cut the key; and a controller for controlling the movement system to carry out a predetermined sequence of movements according to code information. The code information is referenced with respect to a blank edge of a side of the key to be cut, and the predetermined sequence of movements being referenced to the detected blank edge position. A key is cut with the key held in the vise jaw with a groove of the key aligned with respect to the vise jaw without needing to align the key with respect to a keyrest. For a double sided key having standard code information, the key is placed against a keyrest and the position detector is used to determined the width of the key. The second side of the key is then cut with the key held in the vise jaw with a groove of the key aligned with respect to the vise jaw without needing to align a remaining blank side with respect to a guide. For a double sided key having code information including a width parameter of the key blank, the key is placed against a keyrest and the position detector is used to determined the actual width of the key blank. The predetermined sequence of movements is then modified to compensate for differences in key blank width.

Title: Refrigerant powered actuated ball valve
Inventor: MILLER KENT ALAN
IPC: F16K31/40
Filed: 1997-02-11
Granted: 2000-11-07
Abstract: A refrigerant powered actuated ball valve for use in the fluid circuit of a refrigeration or air conditioning system which can be remotely controlled by a low amperage control signal is disclosed.   The actuated ball valve harnesses the pressurized refrigerant from the fluid circuit in which it is installed as the primary power medium to actuate the valve.  The valve includes actuation means with a manifold having an inlet port which is in constant fluid communication with a high-pressure side of the fluid circuit.  Pressurized refrigerant supplied to the manifold is branched to a series of fluid channels running through the manifold.  Exhaust port operators are mounted in conjunction with the manifold to connect the actuation means to the low-pressure side of the fluid circuit and to direct the flow of pressurized refrigerant to either an exhaust port or the manifold.  A reciprocal member disposed within the manifold engages a pinion such that a linear displacement of the reciprocal member causes a corresponding angular displacement of the pinion member. Cycling of the ball valve between an opened position and a closed position is achieved when the pressurized refrigerant is applied to the reciprocal member thereby causing a stem operator on the ball valve to rotate.
