Title: Apparatus for gripping a down hole tubular for rotation
Inventor: WILLIS CLYDE A
IPC: E21B4/00
Filed: 1991-08-02
Abstract: ABSTRACT OF THE DISCLOSURE         An apparatus for gripping a down hole tubular for rotation in a drilling machine includes a support member adapted for connection to the quill of the drilling machine.  The support member supports three or more guides which converge toward one another in a selected direction.  A clamping dog or engaging member is mounted to slide in each of the guides to move into engagement with a down hole tubular when positioned toward a first end of the guide and out of engagement with the down hole tubular when positioned toward a second end of the guide.  A linkage interconnects the engaging members, and includes an actuating member exposed at an upper portion of the support member. This actuating member moves vertically along an axis between open and closed positions, which causes the engaging members to release or engage the tubular.  The actuating member itself bears against an additional element on the top head drive assembly of the drilling machine which can be moved vertically to cause the clamping dogs to engage or release the tubular.
Patent CA-2051689-A1 (CA)
Inventor: HAKIEL ZBIGNIEW
IPC: B65H75/24
Filed: 1990-04-09
Abstract: A core for winding a web of deformable material, such as photographic film base, which has knurlings along its margins. The core (10) includes a rigid cylindrical member (16) with a sleeve (18) of resilient material. The sleeve has a cylindrical outer surface and has a length less than the distance between the margins containing the knurlings. There are means (20, 22) contiguous with the ends of the sleeves for providing cylindrical surfaces having diameters substantially equal to that of the sleeve. These means underlie the knurlings in the web when the web is wound on the core and may take the form of resilient material which is harder than the sleeve, or they may be rigid. In the latter case the surface-providing means may be integral with the rigid cylindri-cal member.

Abstract: IN THE ABSTRACT     A method for making gypsum wall board in which during the production of the board pressure is applied to a portion or all of the board surface to reshape, compress and densify the gypsum core to change the shape or contour the face surface of the gypsum board.  The pressure must be applied in a systematic fashion to avoid creating lateral shifting or shear stresses in the gypsum core or between the core and paper surface to avoid destroying the paper to gypsum core bond.  The method can be used to produce a cross taper at the cut ends of the board, to produce a decoratively shaped board surface and to densify the entire board core for special gypsum board applications.

Patent CA-2080154-A1 (CA)
Title: Toilet Soap Bars
Inventor: CHAMBERS JOHN G
IPC: C11D1/90
Filed: 1992-10-08
Abstract: Soap bars contain from 90-50% fatty acid soaps obtained from tallow (non-lauric fats) and 10-50% of fatty acid soaps obtained from coconut (lauric fats).  Known solutions to the problem of harshness include reduction of the level of soap present and replacement of the balance of the composition by so-called co-actives.  A recognised problem engendered by the presence of co-actives is a loss of product structure in the resulting soap bars.  Soap bars which comprise co-actives must therefore be manufactured by a process which increase the cost of the eventual products.  The invention provides soap bars which comprise:   a)   At least 25%wt on total actives of lauric acid soaps, b)   As the balance of the soaps, non-lauric soaps having an iodine value of less than 45, and, c)   At least 5%wt on total actives of one or more synergistic mildness active.            These soap bars have acceptable mildness but can be manufactured with conventional processing equipment.

The resultant diene polymers or copolymers have improved raw polymer viscosity and when compounded with carbon black have good processability in the uncured state and reduced hysteresis in the cured state. The polymers can be utilized to form elastomer compositions for tire treads having reduced rolling resistance.
Patent CA-2082609-A1 (CA)
Inventor: WALSH JAMES P
IPC: H04M11/06
Filed: 1992-11-10
Abstract: A computer is programmed in accordance with an algorithm which allows it to send a series of tentative unique initialization commands to a port which should be connected to a modem for the purpose of establishing what type of modem is connected if any. In accordance with an internal flag setting, an appropriate translation table is then used in any future communications with that modem to convert the basic commands used by the computer operated device to commands that will be recognized by the modem in setting up communications with other modems at the other end of a transmission line and for terminating said communications. The algorithm involved is also able to ascertain whether or not an operable modem is connected to a port by monitoring the responses obtained. Thus, modems can be changed and potential technician error is eliminated due to the dynamic selection capabilities of the computer programmed to operate in accordance with the inventive concept algorithm.

Abstract: A ladder climbing saftey clamp that may be easily operated by a worker with one hand while overcoming many potential safety hazards of prior devices.  The safety clamp includes a body with a U-shaped cable sleeve.   A channel is included on one side of the body to permit the introduction  of  the  safety line  in  the  cable  sleeve. However, if the cable is too large to operate properly with the safety clamp,  it will not fit through the channel, thereby helping to prevent inadvertent usage of the safety clamp with a cable of a diameter for which it is not intended.  A gravity stop is also provided to prevent the safety  clamp  from being  inadvertently  installed  in an upside-down position,  since the safety clamp would not operate correctly in that position.

Title: Process for recovery of free aluminum from aluminum dross or aluminum scrap using plasma energy at high enthalpy
Inventor: LINDSAY RICHARD D
IPC: C01F7/02
Filed: 1993-02-26
Abstract: A process for recovering free aluminum and aluminum compounds such as aluminum oxide from aluminum dross and aluminum scrap in a furnace heated with a plasma arc torch wherein air at high enthalpy is used as the arc gas. The use of air at high enthalpy as the arc gas provides for more rapid heat output, causing the outer surface or shell of dross to heat rapidly, thereby rupturing the oxide shell releasing free aluminum from within the shell. A higher aluminum recovery is obtained. In a plasma torch high enthalpy is obtained by adding a gas such as CO2, methane or hydrogen to the air arc gas at a fixed current level or by operating the plasma torch with higher current at a fixed air flow.
