Title: Pin ovens and transfer devices therefor
Inventor: BURKE DAVID J
IPC: B65G17/40
Filed: 1991-12-18
Abstract: A B S T R A C T            "PIN OVENS AND TRANSFER DEVICES THEREFOR"       A  pin oven for stoving a decorative or other coating laid down by a rotary decorator (28") on cans has an associated transfer device (40") by which the cans are decelerated and transferred in succession from the decorator onto the chain (20") of the oven.  The chain carries two rows of pins which are arranged in staggered and offset relation.  By operating at a smaller chain circulating speed than the can output velocity of the decorator, the oven provides benefits in the size and thermal efficiency of the oven and reduced chain wear.

Patent CA-2065394-A1 (CA)
Inventor: BOULIGNY VERNON J JR
IPC: E21B19/16
Filed: 1990-08-15
Abstract: An apparatus for gripping tubular members about their outer diameter without causing surface damage or structural deformation to the tubular members, so that they may be axially rotated or secured against axial rotation. A generally cylindrical internal sleeve is contained within a molded flexible liner. One side of the internal sleeve is releasably attached to the flexible liner, forming an annular bladder-like structure within the flexible liner. Introduction of pressure into the bladder-like structure causes the flexible liner to inflate radially inward and thereby grip tubular workpieces within the friction grip. Axial splines on the releasable side of internal sleeve interfit mate with corresponding splines of the molded flexible liner, thereby evenly distribute torque forces throughout the flexible liner rather than such torque forces being concentrated at only the edges of the flexible liner. Movable anti-extrusion rings at the axial edges of the flexible linear prevent deformation of the liner into the annular space between the outer sleeve of the friction grip, and also prevent wear between the axial edges of the liner and the edges of the outer sleeve. An additional, non-rigid sleeve, or coating, of friction enhancing material may be placed on the inner face of the flexible liner to increase the frictional characteristics of the grip and/or increase service life of the surface of the flexible liner. Instead of being made of one annular section, the friction grip may be made of two, or more, hingedly connected sections so as to allow the gripper to be attached at the midpoint of tubular workpieces without having to slide it over one end of workpiece.

Title: Optical fiber cable having dripless, non-bleeding and optical fiber coating-compatible waterblocking material in core thereof
Inventor: TU CHING-FANG
IPC: G02B6/44
Filed: 1992-04-23
Abstract: Abstract An optical fiber cable (20) includes a core which (22) is filled with a filling material (26) comprising a composition of matter which passes industry wide drip tests, which substantially has no oil separation and which has excellent thermal oxidative stability. The filling composition includes a relatively high molecular weight aliphatic hydrocarbon which may be a polyalphaolefin, for example, or a relatively high molecular weight mineral oil. Also included in the composition of the filling material is a fumed silica, a block copolymer and a relatively high amount of an antioxidant system. Swelling of coating materials for optical fibers (25,25) which are relatively soft and which are in contact with the filling material is substantially less than that experienced with prior art filling materials. Because of the inclusion of a low pour point aliphatic hydrocarbon in the filling material, the cable provides excellent optical performance at low temperatures.

Title: Automatic flowgraph generation for program analysis and translation
Inventor: SITES RICHARD L
IPC: G06F9/45
Filed: 1992-03-05
Abstract: A program is translated by automatically generating a flowgraph, using the flowgraph to analyze the program to provide information about blocks of instructions in the flowgraph, and then using the flowgraph and the information about the blocks of instructions to generate translated instructions. The flowgraph is used during analysis of the program to control gathering and storage of information about the blocks of instructions and checking for consistency of the information over paths in the flowgraph. The information for each block includes, for example, register usage, stack usage, condition code usage, return mask usage, and any occurrence of non-standard returns. This information is used to detect possible errors and translation difficulties such as stack depths that do not match on all incoming paths, return masks that do not match over all incoming paths to a block, use of uninitialized registers or condition codes, failure to align the stack on longword boundaries, and nonstandard returns such as callbacks to procedure parameters. An error discovered during analysis is reported, for example, by generating an error-specific flowgraph in which the paths and blocks of instructions relevant to the error are indicated.

Title: Fourth-order-product phase difference autofocus

Abstract: FOURTH-ORDER-PRODUCT                        PHASE DIFFERENCE AUTOFOCUS                                    ABSTRACT   The present invention is a computational method, defined by a computational algorithm, that automatically corrects synthetic array radar (SAR) focus errors more accurately than conventional procedures.  The novel feature is that the present method estimates residual phase errors by forming fourth-order subarray products in lieu of conventional second-order subarray products.  As a result, a pull-in range for residual phase errors is vastly improved.  The present invention advances the state of the art by creating a SAR autofocus method that has an unlimited pull-in range for both a quad-ratic and a cubic phase errors.  The invention thus extends the operational range and resolution of SAR systems, and enables the effective use of the SAR sensor with a limited (less expensive) motion compensation subsystem.  The present invention provides for a phase difference autofocus method that estimates the residual quadratic and cubic phase error that often requires only one autofocus iteration.
