Title: Process for preparing y-mercaptocarboxylic acid derivatives
Inventor: QUITTMANN WILHELM
IPC: C07C319/02
Filed: 1994-08-23
Abstract: .gamma.-Mercaptocarboxylic acids and their derivatives, in particular esters and amides, are prepared from .gamma.-butyrolactones via the corresponding thiolactones. The thiolactones are obtained by reaction of the lactones with thiocarboxylates in polar solvents and are converted into the .gamma.-mercaptocarboxylic acid derivatives by ring opening using nucleophilic reagents such as, for example, alkali metal alkoxides. The products are intermediates, for example for the synthesis of leucotriene antagonists.

Title: Apparatus and method for mounting an electrical box between studs in a wall
Inventor: OLIVA JOHN H
IPC: H02G3/12
Filed: 1994-01-04
Abstract: An improved apparatus and method for mounting an electrical box between sands in a wall is disclosed. The apparatus of the invention is a mounting bracket comprising a relatively flat, elongated frame having a front planar face, a rear planar face, and a first and second opposing ends attachable to two corresponding wall studs. The frame also has a central cut-out portion which defines a top edge and a bottom edge. An electrical box and its accompanying faceplate may be mounted between two wall studs by first attaching the bracket of the present invention to the wall studs. The open front end of the box is then placed flush against the rear face of the bracket such that a top portion of the box contacts the top edge of the bracket and a bottom portion of the box contacts the bottom edge of the bracket. Similarly, the accompanying faceplate is placed on the front face of the bracket opposite and aligned with the box such that a top portion of the faceplate contacts the top edge and a bottom portion of the faceplate contacts the bottom edge. The mounting is completed by fastening the box and the faceplate to the bracket. Mounted in this manner, the front end of the box will be substantially flush with the plane formed by the wall studs regardless of the depth of the box.

IPC: C10G70/04
Filed: 1994-11-01
Abstract: A hydrocarbon stream is cracked to produce a hot gaseous stream which is compressed and cooled to condense almost all of the hydrocarbons contained in the stream. A noncondensed stream remaining after the condensation step, comprised predominantly of hydrogen and C1 to C3 hydrocarbons, is subjected to pressure swing adsorption or temperature swing adsorption at an adsorption temperature of about 0 to about 250° C in a bed of adsorbent which selectively adsorbs ethylene and propylene, thereby adsorbing substantially all of the ethylene and propylene from the gas stream. The ethylene and/or propylene is recovered upon bed regeneration.

Filed: 1995-03-07
Abstract: Electric cables with sector-shaped conductors, for maximizing duct capacity, are made by a process in which the shaped metallic conductor is first preformed into a helical twisted form ("pre-spiralled"), next covered with insulation of EPR, polyethylene or other suitable insulation material to form a core, third subjected to ionizing radiation to crosslink the insulation, and fourth laid up with other like cores to form a cable. All the steps are well known yet the potential to apply radiation crosslinking to this type of cable - in which other crosslinking techniques are wholly impracticable - has not hitherto been appreciated.

Patent CA-2151598-A1 (CA)
Inventor: COUCH RICHARD W
IPC: B23K26/14
Filed: 1993-12-10
Abstract: Plasma arc or laser cutting uses a mix of reactive (24a) and reducing gas flows (22a) to cut sheets (14) of stainless steel aluminum and other non-ferrous metals. The reducing gas flow (22a) to the cut varies as a percentage of the total gas flow to maintain a reducing atmosphere down through the cut (12), but to leave a predominantly oxidizing atmosphere at the intersection of the cut (12) and the bottom surface (14B) of the sheet (14) being cut. In plasma arc cutting these flows can also be characterized as eithe a plasma gas flow (22a) that forms the arc, or a shield gas flow (24a) that surrounds the arc. The reactive gas is preferably a flow of air, oxygen, nitrogen, carbon dioxide or a combination of these gases. The reducing gas is preferably hydrogen, hydrogen 35, methane, or a mixture of these gases. For aluminum the reactive gas is preferably air or nitrogen and the reducing gas is preferably methane or a mixture of methane and air. In laser cutting the reducing gases such as methane can be used by mixing them with reactive assist gases.

Abstract: An air bag inflator (20) includes gas stored at or above a predetermined pressure in a chamber (24) in a container (22).  An initiator (10) connected with the container (22) is exposed to the pressure of the gas stored in the chamber (24).  A closure can (120) of the initiator (10) includes an electrically conductive sensor portion (140) which is spaced apart from an electrically conductive contact can (200) when the pressure in the chamber (24) is at or above the predetermined pressure.  If the pressure in the chamber (24) drops below the predetermined pressure, the sensor portion (140) moves into electrical contact with the contact can (200).  The engagement of the sensor portion (140) with the contact can (200) completes an electrical circuit to provide an indication of low pressure in the inflator (20).
