Title: Water treatment installation for a tangential filtration loop
Inventor: FAIVRE MICHEL
IPC: C02F1/72
Filed: 1990-12-11
Abstract: An installation for the filtration and cleansing of liquids, notably water, of the type having a loop for the circulation of the water to be treated, including at least one tangential filtration membrane, comprising a new tangential membrane filtration installation, with ozone injection, enabling the surface, internal and chemical clogging of the membrane to be restricted. The installation includes means for the addition of an oxidizing gas to the liquid to be treated, in the loop upstream of the membrane, so as to form microbubbles of said gas with a size such that they create turbulence in the liquid at the membrane and this tubulence, combined with the phenomenon of oxidation, restricts the clogging of said membrane and leads to an improvement in the flow rate and in the physi-cal/chemical qualities of the filtrate. If necessary, it includes means for the injecting of chemical reagents and/or absorbents into the filtration loop.

Title: Peeler for garlic or the like with centrifugal discharge
Inventor: FEDERIGHI GEORGE J SR
IPC: A47J17/18
Filed: 1991-03-01
Abstract: PEELER FOR GARLIC OR THE LIKE WITH CENTRIFUGAL DISCHARGE      Abstract of the Disclosure Motor driven apparatus for peeling garlic or similar food products has a housing forming a processing chamber and an abrasive rotary disk in the chamber which abrades the skin or husk from the product.  A movable gate partially obstructs a discharge slot at the side of the chamber.  The gate has a lowered position at which the unobstructed region of the slot is large enough to enable continuous ejection of peelings but too small to allow escape of the product.  The gate is raised at the end of each peeling operation enabling centrifugal ejection of the product by the rotary motion of the disk.    Manual unloading and separation of the peelings and product is unnecessary thereby providing for fast, high throughput oper-ations.  The apparatus may be an accessory which engages on a food processor base.

Abstract: INSULATED GLASS/FLUSH OUTER SURFACE ARRANGEMENT                 Abstract of the Disclosure A  pre-fabricated  window  assembly  for  flush-appearance glazing comprises a conventional single-pane or dual-pane assembly. In the latter case, the spacer el-ements are inset from the peripheral edges of the window assembly.  One of two types of extrusion is provided along each peripheral edge of the window assembly which provides a bonding surface to which the flush mounted lite  is adhered by means of a bonding cement plug.  The extrusion on one side of each pair of opposed sides of the window assembly is provided with a quick push-on  or hook-on connector which mates with a complementary connector on the mullion or grid frame.  The other extrusion on the opposite side of the window unit, for each pair of opposed sides, is similarly  configured,  except  that  the  connector  is  a permanent connector for permanent securing of the extrusion to an appropriate mating fastener on the grid frame.  Where a dual glazed window assembly is used, each of the extru-sions is provided with a channel in which the peripheral edge of the inboard lite is mechanically gripped.   The extrusions, in that event, are also provided with a rib or flange forming with the inner side of the inboard lite a recess into which a bonding agent may be placed to adhere the inner lite to the extrusion.  The extrusions and the bonding cement are all applied in the factory to make the complete pre-fabricated window assembly.

The layers 1,3,5,7 are corrugated along the direction of their circumference such that pressure from the bore through the annular layers causes the corrugations to at least partially unravel, thus causing inflation of the well packer. The fibres 31 within each layer 1,3,5,7 are oriented along the length of the layer, such that their orientations vary along the length of the layers 1,3,5,7.            A method of manufacturing the well packer is also described.            Figure 1 to accompany abstract.
