Patent CA-2535220-C (CA)
Title: Condensation heat exchanger
Inventor: LE MER JOSEPH
IPC: F24H1/43
Filed: 2004-04-23
Granted: 2011-09-27
Abstract: The invention relates to a condensation heat exchanger. The inventive heat exchanger consists of two co-axial helicoidal tube bundles which are positioned end-to-end, one of said bundles (2a) serving as a primary exchanger and the other (2b) serving as a secondary exchanger. Each of the aforementioned bundles comprises a tube and/or a group of flat tubes which are mounted inside a gas-impermeable casing (1). Moreover, means are provided to circulate at least one fluid to be heated inside the tubes, the casing (1) being equipped with a gas exhaust sleeve (122). In this way, a first hot gas, known as the main gas, which is, for example, generated by a burner (6), passes radially through the voids in the bundles. A deflector system (7) ensures that said main hot gas first passes through the primary exchanger (2a) from inside outwards and, subsequently, the secondary exchanger (2b) from outside inwards, after which it is discharged from the exchanger through the above-mentioned sleeve (122). The deflector (7) comprises two adjoining parallel plates (7a, 7b) which are made from a thermally-insulating material. In this way, a second (additional) hot gas can be introduced between the aforementioned plates in order to heat the fluid circulating in the secondary exchanger or to contribute to the heating thereof. The inventive condensation exchanger is suitable, for example, for domestic use.

Title: Method and system for individual tire recycling
Inventor: DEVLIN FRED G III
IPC: B65B27/06
Filed: 2003-08-25
Granted: 2010-11-09
Abstract: The method of the present invention for handling scrap tires, includes a step of providing a compacting apparatus to a scrap tire generator (62), such as a tire retailer. Before compacting the tires, the tire can be marked with a unique identifier (64) assigned to every tire generator. By marking the scrap tires with a unique identifier, the scrap tires can be tracked on their way to the final destination. The compacting apparatus provides volume reduction of the scrap tires individually into a form that can have a reduction of at least fifty percent of original cubic volume (66). The tires can be pinched to maintain the compacted tire in the compacted form (67) and prevent the compacted tire from regaining its original shape. The compacted scrap tires can be accumulated inside a tire collection enclosure (68), such as a trailer or dumpster. The collected tires can be transported with much more weight efficient loads of the tires to a transfer station, a recycling facility, or an end user (69).

Abstract: The invention concerns a lead-through means for cables or pipes comprising an outer frame (11) and having at least one sealing module (1) arranged inside the frame and which at least one module surrounds a cable or a pipe (8). The sealing module (1) is divided in its longitudinal direction and is built up with peelable sheets (3) for adaptation of its duct area to the actual cable or pipe (8) and which sealing module (1) is intended to fill out the opening of the frame (11) together with at least one expansion unit (12). The sealing module (1) has a dividing cut (2') for division into two halves which cut runs obliquely in relation to the longitudinal direction of the sealing module (1) or the longitudinal axis (5) of its duct (4), whereby at an adaptation of the sealing module (1) to the actual cable or pipe (8) one module half (1') may be turned 180~ during a first stage to achieve a conical duct through the sealing module (1) at the same time as an oblique gap (6) is formed between the module halves (1', 20 1''). The module (1) may there after be adapted to the actual cable or pipe (8) until the module halves (1', 1'') reach each other at the narrow end (6') of the gap (6) and which one half (1') during a second stage may be turned back 180~, whereby an even gap (7) having the correct measurements is obtained simultaneously with a complete sealing against the cable or pipe (8) going through the sealing module (1) and the frame (11) after activation of the expansion unit (12).

Abstract: A seed tube for an agricultural implement having a seed metering mechanism for uniformly dispensing seeds. The seed tube defined an enclosed curved seed pathway extending between opposite ends of the tube. To promote control over the seeds passing through the tube, the tube has a smooth but decreasing cross-sectional configuration between the ingress and egress ends of the tube. The tube generally includes a front wall, a rear wall and a pair of side walls. The front wall is generally separated into an upper and lower portion. An opening in the front wall, which is provided to receive a monitoring device, is associated with the lower front wall portion. In addition, the lower front wall portion is stepped forward relative to the upper front wall portion. The enclosed seed pathway further includes a narrowed front edge extending in an upward direction from the egress end of the tube along some section of the front wall. The narrowed front edge enhances control over the seeds such that individual seeds passing through the tube and deposited to the ground have equidistant spacings between the seeds on the ground. The stepped forward arrangement for the lower front wall portion also allows a monitoring device to be used without disrupting the flow of seeds in the seed tube.

Abstract: A filter element for filtering fluids and gasses flowing through a filter housing is provided. The filter element includes a permeable filter media for filtration of contaminants and a rigid frame for supporting and retaining the filter media. To ensure that gasses and fluids flow through the filter media rather than around the filter element, a resilient seal element is attached along an outer peripheral surface of the frame. The seal element can be resiliently compressed between the inner surface of the filter housing and the outer peripheral surface to create a sealing effect therebetween. To prevent the filter media from interfering with the seal element, the filter media is substantially constrained within the outer peripheral surface of the frame.
