Title: Separation of particulate from gases produced by combustion of fossil material
Inventor: HALDIPUR GAURANG B
IPC: B01D51/00
Filed: 1992-02-10
Abstract: 56,212 ABSTRACT OF THE DISCLOSURE Apparatus and method for separating particulate from gas produced by combustion of fossil fuel including a main vessel having a lower compartment in which the fuel is burned and an upper compartment in which the separation of particulate takes place.  The separation is effected by combining roughing cyclones for separating the larger particulate with modules of cross-flow filters for separa-ting the residual smaller particulate which emerges from the cyclones.  The upper compartment includes a plurality of pressure vessels each containing a cyclone and modules of cross-flow filters mounted vertically.  In each module the cross-flow filters are divided into an upper cluster, middle cluster and a bottom cluster.  In each of the upper and middle clusters the cross-flow filters are arrayed or stacked vertically in columns in T configuration.  In the bottom cluster the filters are arrayed in cruciform con-figuration.  Each cluster has a separate pipe for conducting gas processed by the cross-flow filters out and pulses for cleaning the cross-flow filters in.  The cleaning gas is conducted in succession through the separate pipes.  The middle cluster is rotated about 120° about its vertical axis with respect to the upper cluster to afford clearance for the respective pipes from these clusters.  The vertical axes of the pipes from the three clusters are spaced by 120° from each other.

Title: Implantable blood pump
Inventor: POL VINCENT
IPC: A61M60/443
Filed: 1992-03-18
Abstract: The invention relates to an implantable blood pump of the type comprising a shell, a closed deformable bag, an inlet valve and an outlet valve, a drum arranged to roll over a wall of the bag, a bracket mounted to rotate about the axis of the drum and connected by an inextensible flexible component to one of the end edges of the bag, and an electric motor integrated inside the drum and suitable for driving the bracket and the drum in mutual and antagonistic rotation over a fraction of a turn to compress the bag which winds onto the drum to expel blood fluid. According to the invention, the outer shell is rigid and constitutes a sealed housing in which the bag can deform, and the bag is made, at least in part, of a material that is inextensible in two directions so that its original volume remains constant, said bag thus being made insensitive to external underpressure tending to increase its volume while blood fluid is being expelled. The invention is applicable to making non-displacement peristaltic cardiac prosthesis.

Title: Rod and case assembly and panic exit device
Inventor: O'BRIEN JAMES
IPC: E05B63/04
Filed: 1992-04-02
Abstract: ABSTRACT OF THE DISCLOSURE     A rod casing for activating vertically arranged latch bolts, the casing and latch bolts arranged in an active stile of a door and engageable to a door frame. The rod easing provides a vertically slidable actuator cam engageable by both a lock/unlock actuator and a delatch or dogging actuator. The lock/unlock actuator and the delatch actuator are rotatably mounted upon a spindle piece which itself is rotatable by a user such as by a key-activated lock cylinder. The lock/unlock actuator when rotated, slidingly abuts the actuator cam and drives the actuator cam vertically upward to cause unlatching of the latch bolts. The delatch actuator, upon rotation of the spindle piece in an opposite direction underlies the actuator cam and dogs the actuator cam in its vertically risen position. A panic exit device is also provided which has a lift plate mounted fixedly to the rod slide, the lift plate liftable by a pivoting of a lift lever, the lift lever pivoted by a lateral thrusting of a push plate slidably held beneath a push pad of the panic exit device. When compressed by a user, the push pad compresses two motion actuators housed beneath the push pad which laterally translate the push plate toward the lift lever.          A spring loaded panic exit device dogging mechanism is also provided.

Abstract: ABSTRACT   The invention provides a method of applying a design by a printing process to anexpanse of material which is dimensionally unstable, in particular genuine tanned leather and synthetic leather, which method includes the steps of adhesively applying the material to a rigid backing plate to define a pictorial area where the material adheres to the backing plate; providing adjustable key means on a print table of a stencil or screen printing apparatus, to demarcate a selected position for the backing plate where a print plate of the printing apparatus will produce a printed image in a desired location on the pictorial area; positioning the backing plate in the demarcated position with reference to the key means; and printing a printed image in the desired locality on the pictorial area.   The key means is preferably a displaceable base plate which can be placed in a desired position on the print table. The base plate has keying pins to engage with keying apertures in a backing plate.   To achieve an accurate placement of successive images where a multi-colour design is to be printed, a transparent overlay sheet is provided over the pictorial area, and a trial image is printed on the overlay sheet, whereupon the position of the base plate is adjusted with reference to the trial image.
