Patent CA-2029260-A1 (CA)
Inventor: EHRENFELS ALFRED L
IPC: H01R25/16
Filed: 1990-11-02
Abstract: A pin and sleeve receptacle is mountable in a wall box recessed in a wall opening of a building with wires extending into the box from an in-wall wiring passage. The receptacle has a tubular electrically non-conductive shell closed at one end, the other end being open and a flange with fastener openings at the open end of the shell. A cylindrical inner body has an outer diameter smaller than the first inner diameter, the inner body having female connector sleeves for receiving electrically conductive pins of a mating plug.   The inner body is mounted within the shell with an annular gap surrounding the inner body for receiving the shroud of the pin-and-sleeve plug. The openings at one end face in the same direction as the open end of the shell to receive the pins of the plug. Apertures in the shell admit wires from the box for connection to the electrically conductive female connectors. An adapter plate has a central opening to receive the shell, holes to receive fasteners extending through the fastener openings in the flange and holes to permit passage of fasteners for mounting the plate across the opening of the recessed wall box. A cover plate has a central opening surrounding the open end of the shroud, openings for passage of fasteners for attaching the cover plate to the adapter plate with the flange in between, and sloping side edges for abutting the wall surrounding the box to form a minimally protruding assembly. A right-angle plug having pin connectors to mate with the receptacle to form a connector assembly with minimum protrusion from the wall as disclosed.

Inventor: PANIGRAHY SARAT C
IPC: C21B3/02
Filed: 1990-11-14
Abstract: ABSTRACT OF THE DISCLOSURE            An improved iron ore sinter for use in a blast furnace is made from a raw sinter mix comprising:  iron-bearing materials; basic fluxes including a source of CaO and a source of MgO; and solid carbon-bearing material   usually coke breeze, used as a heat-generating combustible.  To produce the sinter, the raw sinter mix is subjected to a sintering treatment at a high temperature in order to cause the iron-bearing materials,  fluxes and carbon-bearing material to agglomerate and sinter by incipient fusion; an air-cooling treatment in order to produce a hard lumpy substance having a porous cellular structure;  and a mechanical treatment to break the lumpy substance into a specific size range.  The improvement to the above sinter lies in that the source of MgO in the raw sinter mix exclusively consists of synthetic olivine obtained by calcination of serpentinite.   Such a use of synthetic olivine has numerous and unexpected advantages over the use of natural olivine as a source of MgO in the manufacture of iron ore sinter for blast furnace, especially in terms of enhanced sinter strength,  improved sinter reduction properties and productivity.

Title: Esterification process
Inventor: VAN DEN BERG HENDRIKUS J
IPC: C07C67/08
Filed: 1990-12-19
Abstract: ABSTRACT    The invention provides a process for the esterification of a C2-C24 monocarboxylic acid with a C1-C5 monoalcohol in a reactor at an increased reaction temperature and increased pressure which is carried out in the absence of any esterification catalyst whilst continuously feeding in the alcohol during the reaction and removing a gaseous alcohol/water mixture.  Preferably the process is carried out in countercurrent in column reactor which is packed or contains plates.  The reaction temperature is usually between 200 and 260°C at a pressure between 0.5 and 1.5 MPa.  There is a C6-C20 monocarboxylic acid and monoalcohol a C1-C3 monoalcohol.  More preferably the process is carried in two steps with a first step as described above and a second step in which further reaction to a conversion of at least 99% is carried out in the presence of an esterification catalyst at a temperature below 100°C.

Title: Fire fighting foam mixing system
Inventor: GRINDLEY JOHN R
IPC: A62C25/00
Filed: 1991-04-18
Abstract: ABSTRACT OF THE DISCLOSURE   A fire fighting foam proportioner for use in providing precise proportioning of foam to fire fighting liquid, e. g. water, is disclosed.  It includes a tank for the storage of foam concentrate which is loaded using a hand pump.   The storage tank is coupled to a fire fighting line through a differential pressure responsive valve in the fire fighting line and a proportioning valve used to select the foam concentration desired, for example 0.2 to 1 percent of the fire fighting liquid.  The differential pressure responsive valve applies discharge pressure to the foam concentrate as a function of the fluid flow through the line and therefore provides  precise  flow  concentration  maintenance  despite changes if flow and line pressure.  The differential pressure responsive valve includes to coaxial valving members and low and high pressure ports which are coupled to control the discharged pressure to the tank.   The proportioner valve include a rotor with a continuous variable groove for precise control.           I:\PATENT\GRINDLEY\FRGNAPPL.03

Abstract: An improved locking mechanism for detachably securing a seat back to a chair frame is disclosed. The improved locking mechanism includes a pair of side brackets secured to opposite sides of the seat back. Linkages supported from the chair frame are provided for receiving the slide brackets thereon for supporting the seat back on the chair frame in a predetermined orientation relative to the seat member. A moveable locking arm is supported from the slide brackets and includes an offsetarcuate cam surface which is adapted to engage an arcuate notch formed on the linkage when the locking arm is moved to a locked position. The mating engagement of the arcuate offset cam surface within the arcuate notch generates a line-of-contact therebetween which inhibits relative movement between the slide brackets and theupstanding links for rigidly securing seat member to the chair frame. An alternative embodiment discloses a modified link member which is adapted to create an interference engagement with the slide bracket to augment the locking action of the arcuate cam surface within the arcuate notch.
