Title: Melamine of improved purity produced by high-pressure, non-catalytic process
Inventor: BEST DAVID
IPC: C07D251/62
Filed: 1996-05-28
Abstract: A high-pressure, non-catalytic process for producing melamine from urea wherein the melamine is recovered directly as a dry powder without washing or recrystallization is described.

Patent CA-2179707-A1 (CA)
Inventor: ECKER ROBERT J
IPC: E05B75/00
Filed: 1996-06-21
Abstract: An improved hinge assembly is disclosed for interconnecting a pair of handcuffs.In the preferred embodiment, the hinge assembly comprises two parallel single-link hinges that are pivotally attached to the cuffs by trunnion pins. Each link has unique oversized slots, through which the pins extend. This permits the cuffs, when side-by-side, to collapse against one another; and it enables the cuffs to move away from each other for compact wearing over a user's belt. In addition, the trunnion pins are captured within the cuff frames. This avoids tampering found with exposed pivot pins in prior multi-link hinges.

Patent CA-2187273-A1 (CA)
Title: Plastic container and lid with tab
Inventor: MAZZAROLO IVONIS
IPC: B65D1/14
Filed: 1996-10-07
Abstract: The disclosure describes the combination of a plastic container and of a plastic lid which are adapted to be hermetically sealed to one another.  The lid defines a tab that projects outwardly and includes a tangentially extending indentation that separates the tab into an inner portion and an outer portion.  The indentation forms a hinge so that upward forces exerted accidentally on the tab causes only the outer portion of the tab to pivot about the indentation thereby preventing the inner tab portion from lifting and detaching the hermetically sealed lid portion from the container. The hinge also serves to enable the tab to be placed in a downwards pivoted position where it is fixedly attached to the container side wall prior to being used.

Title: Production of benzene, toluene and xylene (btx) from fcc naphtha
Inventor: TIMKEN HYE KYUNG CHO
IPC: C10G35/06
Filed: 1997-07-21
Abstract: Cracked naphtha feeds such as FCC naphtha and coker naphtha are upgraded to produce chemical grade BTX (benzene, toluene, xylene with ethylbenzene) while co-poducing a low sulfur gasoline of relatively high octane number. The cracked, sulfur-containing naphtha is processed by hydrodesulfurization followed by treatment over an acidic catalyst, preferably a zeolite such as ZSM-5 or zeolite beta with a hydrogenation component, preferably molybdenum.  The treatment over the acidic catalyst in the second step restores the octane loss which takes place as a result of the hydrogenative treatment and results in a low sulfur gasoline product to permit a low sulfur gasoline of blending quality to be obtained with the BTX. The BTX can be extracted from the second stage effluent, preferably from a C6 - C8 fraction of this effluent.
