Title: Polymer cracking
Inventor: HARDMAN STEPHEN
IPC: C07B61/00
Filed: 1993-04-20
Granted: 2001-01-23
Abstract: This invention relates to a process for cracking waste polymers in a fluidized bed reactor to produce vaporous products comprising primary products which can be further processed, eg in a steam cracker to produce olefins, characterized in that the vaporous products are treated to generate a primary product substantially free of a high molecular weight tail having molecular weights >700 prior to further processing. The removal of the high molecular weight tail minimises fouling and prolongs the lifetime of the reactors used for further processing.

Abstract: A clinch type staple has a U-shaped configuration with a pair of legs extending generally perpendicularly from a base portion of the staple with the outside surfaces of the distal ends of the legs being-bevelled. The legs of the staple lie in spaced apart planes that are parallel to one another, but are angularly offset from one another in order to insure that the legs will not contact or interfere with each other as they are clinched into a workpiece.  A plurality of such clinch staples can be manufactured into an assembly of clinch staples.  The method of  making such an assembly of clinch staples includes advancing a plurality of wires in parallel side-by-side relation in a flat planar array and adhering the wires to one another.  A blank, severed from an end of the formed array, includes a plurality of side-by-side wire segments of equal length extending parallel to one another in a first direction.  The severing of the wires is accomplished along a cutting line that is inclined by a bias angle from a perpendicular to the first direction.  The blank is bent along two bending lines to form a U-shaped stick of clinch staples with the legs extending perpendicularly from a base or bight portion of the staples.  The two bending lines are parallel to the cutting line so that the legs of the formed staples will be offset angularly from each other.

Title: Three-dimensional puzzle game
Inventor: BENOIT PIERRE
IPC: A63F9/12
Filed: 1994-05-25
Granted: 2000-03-21
Abstract: A corner element of a puzzle game that constitutes a three-dimensional pictorial representation of a structure such as a building-like structure. The corner element comprises first and second backing members bonded to a flexible lithographic film. A hinge area separates the first and second backing members, allowing to bring them in a corner configuration by folding the lithographic film at the hinge area. The film has an exposed image-bearing surface constituting a pictorial entity that contributes to a complete representation of the structure. The corner element is made from a blank that includes a layer of backing material laminated to the lithographic film. The backing material is die-cut at controlled depth to form the first and second backing members in a spaced apart relationship, separated by a waste strip. Prior to assembling the puzzle pieces, the user is required to peel off the waste strip from the blank in order to form the hinge area between the first and second backing members.

Abstract: An in-die tapping tool (1) having particular applica-tion to a progressive die method for threading holes (108) in a sheet metal workpiece (106). The tapping tool (1) in-cludes a transmission system comprising a threaded shaft assembly (26) and a planetary roller nut (42). The roller nut (42) is adapted to move axially along the shaft assem-bly (26) in response to an impact force applied to the tap-ping tool (1) during the downstroke of the press. The movement of the roller nut (42) causes the shaft assembly (26) to rotate which rotation is imparted to a threaded lead screw (70) to cause the lead screw (70) to simultaneously rotate and ride axially along a threaded wall (7) of a hol-low cylindrical body (6). The rotational and axial move-ments of the lead screw (70) through the cylindrical body (6) are transferred to the tap (56) to correspondingly in-duce a rotation and advancement of the tap (56) towards the workpiece (106) having the holes (108) to be threaded.

Abstract: An apparatus for processing the speech information includes a first execution device and a second execution device for executing operations at respective different execution cycles, and a first memory unit for reading and recording the speech information. The first execution device and them second execution device exploit the first memory unit in common for processing the speech information. The processing apparatus further includes a second memory unit for storage of the speech information from the first execution means or the speech information read out from the first memory unit. The first execution device records the speech information on or reads the speech information from the second memory unit during the execution cycle of the first execution device. The second execution device accesses the first memory unit during the execution cycle of the second execution device for outputting the speech information to outside. The speech information recorded in the second memory unit is read out and recorded in the first memory unit or the speech information recorded in the first memory unit is read out recorded in the second memory unit during the time of not accessing the first memory unit. The data transfer between first execution device and the second memory can be performed during the execution cycle of the first execution device, while that between the second memory unit and the first memory unit can be performed during the execution cycle of the second execution device, so that it is possible for the first execution device to perform data transfer independently, such that sound source data can be transferred at a higher speed by employing a high-speed device as the first execution device.

Title: Laser sensor capable of measuring distance, velocity, and acceleration
Inventor: WILSON MARK L
IPC: G01S17/36
Filed: 1994-09-28
Granted: 2006-04-11
Abstract: A light based distance, velocity and acceleration sensor which uses phase difference to determine the desired measurement.  A laser signal is modulated by an oscillator signal and reflected off an object to a signal receiver. The reflected laser signal and the oscillator signal then pass through a dual path conditioning circuit, where the path lengths and circuit elements of the two paths are identical to cancel the effets of propagation delays in an output signal. The conditioned signals are passed through a phase comparator, to produce a signal indicative of the phase difference between the oscillator signal and the reflected laser signal. The phase difference is directly proportional to the distance between the sensor and the object.
