IPC: B01D17/038
Filed: 1988-07-28
Abstract: The liquid to be treated enters via the central channel (1) to leave, in the form of two liquid phases of different densities, through the conduits (4, 5), sealing discs (6, 11, 19) being mounted respectively on the central body (7), on the intermediate disc (12) and on the upper cover (20) of the machine. Resting against these discs are movable rings (8, 13, 14, 17) subjected to the pressure, on the one hand, of the liquid introduced into the machine and, on the other hand, of the two liquid phases separated by the latter, while providing a perfect seal between the different phases, without the need for providing elastic return members and without it being necessary to resort to special cooling means. <IMAGE>

Abstract: A child resistant dispensing closure (10) characterized by a closure member (12) and a lid member (14) which is mounted on the closure member (12) for movement between closed and open positions. A peripheral edge of the lid member (14) abuts an annular shoulder (22) provided on the closure member (12) in the closed position, the point of abutment being concealed by an annular ring (24) provided on the closure member (12). In the closed position, thickened portions provided on the peripheral edge of the lid member (14) engage in recesses formed in the annular shoulder (22). The lid member (14) is adapted to be moved upwardly from the closed to an open position when a user applies with one hand a manual compressive force to a panel provided on the exterior skirt (18) of the closure member (12). This manual force results in deformation of the panel inwardly into a slot formed clearly through an enlarged portion of the shoulder (22). As a result, a slight separation occurs between the peripheral edge of the lid member (14) and the shoulder (22) so as to allow the user, with the other hand and while continuing to compress the panel, to engage the peripheral edge of the lid member (14) for moving the lid member (14) to the open position.

Abstract: A lidded container (1) is provided which is intended to deter unauthorised removal of the lid (2). The container has an out-turned lip (3) of inverted U-section having a circumferential horizontal flange (8) supporting an upright retention portion (10) with a retaining bead (12). The lid (2) has a rim portion (14) which is also of inverted U-section, the web (15) of the U having a formation (20) engaging a complementary formation (21) on the lip (3) of the container to provide location and sealing connection between the lid and container, and the outer limb (17) being outwardly cranked and forming a depending skirt (18) having a retaining formation (19) which interlocks with the retaining formation (12). 
     Part of the flange (8) is extended to form a tab (22) which is removable at a line of weakening (23) to facilitate separation of the lid (2) and container (1). Removal of the tab (22) indicates that the container has been opened or at least that it has been tampered with.

Abstract: A liquefied gas operated caulk dispensing gun with a housing sub-assembly (10) having an elongate tubular housing (16) defining a chamber (18) for accommodating a tube of caulk, an open dispensing end and an opposite valved closed end portion. A material dispensing sub-assembly (12) is also provided removably connected to the dispensing end of the housing sub-assembly (10) to form a dispensing assembly. The dispensing sub-assembly (12) includes a nozzle (40), a caulk flow passage (37) communicating with the chamber housing (16), wherein the flow passage (37) is sized to accommodate a caulking tube outlet. The material sub-­assembly (12) also includes a valve controlled passage for selective communication between an inlet portion of the flow passage and the nozzle (40), and a flow control valve (48) movable between open and closed positions to control such selective communication. A seal mechanism is positioned in the dispensing assembly to effect a seal between the flow passage (37) and a charge receiving portion of the chamber (18). A valve (48) is included on the valved end portion of the housing to permit liquefied gas to enter the charge receiving portion for the dispensing of caulk, and for venting the charge receiving portion when the housing sub-assembly (10) is to be disconnected from the material sub-assembly (12). A lever mechanism is operatively connected to the flow control valve (48) for moving the valve (48) from one position toward the other.

IPC: B01D21/00
Filed: 1988-11-16
Abstract: For separation of sludge and free hydrocarbons, the contaminated waste water is emptied into the collecting pond (1). Gravel and particulate contaminants are retained on the grid (9). Coarse deposits collect in the sludge channel (5), from where they are removed with a grab. Water given this preliminary purification flows through the overflow (12) into the settling pond (2), where in the course of a long residence time fine sludge separates and sinks to the base (10). When the water level in the settling pond has reached a predetermined maximum height, the water is pumped off to a determinable minimal height, and passed for further treatment to the treatment tank (19). Hydrocarbons that have collected are removed from time to time by suction. The deposited fine sludge, when the ponds (1, 2) are emptied, is pushed through the ducts (13) into the collecting pond (1) and removed together with the deposits that have collected in the sludge channel (5). According to an advantageous embodiment of the concept of the invention, the ponds (1, 2) are subdivided, by walls arranged in parallel to the plane of the drawing, into sections that are connected by the outflow channel (22). This allows individual sections to be closed off for repair and cleaning purposes and to maintain operations fully with the remaining sections. <IMAGE>

Abstract: A tunnel module consists of an upper part (1), which is downwardly delimited by high-performance filters (15), and two side walls (3, 4). The upper part (1) has three chambers (9, 10, 11) which are divided by two intermediate bottoms (7, 8) and lie on top of one another, a fan (16) and a return air opening (14).

Abstract: Method for forming a porous sheet comprising a plurality of porous sheets (1,2) such as foamed sheet, mesh sheet and nonwoven fabric sheet. These sheets are adhered and layered to each other either by a melting or with an adhesive or by layering without each other with adhering (6a,6b) these sheets to each other. Then, the porous sheet (1,2) thus layered is plated at a high current density by forcibly applying plating liquid to the layered sheet in a direction substantially perpendicular thereto in a plating tank (4), or by vacuum evaporation while the layered sheet is being transported inside the vapor deposition vacuum container enclosed by a cooling tank through a cooling roller mounted therein. The metallic porous sheet formed according the above-described method is preferably used as the electrode of a battery.
