摘要:
An apparatus for pneumatic cleaning of diesel particulate filters (DPF). First and second nozzle members direct flows of compressed air into the axially-extending filter cells from both ends of the filter, the nozzle members generally being offset so as to avoid blowing directly towards one another. The flows form the nozzles impinge only relatively small areas of the end faces of the filter media, e.g., only one or a few cells at a time. The nozzle members are moved over substantially the entirety of the first and second end faces, so that as cleaning progresses compressed air is directed into substantially all of the filter cells from opposite directions. The nozzles may be translated on reciprocated arms while the filter is rotated simultaneously on a turntable or rollers, so that the nozzles sweep over the whole surface of each end; other mechanisms, such as various combinations of gears or pistons, may be used for relative movement between the nozzles and filters. Also, the nozzle members may have single or multiple nozzles. The filter and nozzles are housed within a cabinet having one or more windows therein, which enable an operator to view progress of the cleaning process and determine when it is complete. Visual observation and also enables an operator to identify filters having damaged media, as indicated by particulate material billowing from both ends of the filter due to cracked or broke axial cells. The dislodged particulate material is withdrawn from the cabinet by an exhaust duct system.

A door opening and closing device (114) and an electronic apparatus (100), which can reduce the size of a door (110) of the electronic apparatus (100). The door opening and closing device (114) includes at least one locking surface portion (115) formed at a door (110) of a front panel (102), and at least one locking support portion (120) disposed horizontally to either an upper portion or a lower portion of the component on the front panel (102), for resiliently pressing the locking surface portion (115), to thereby keep the door (110) in an opened position or closed position. A transverse width (D) of a door (110) can be reduced to a range of the transverse width of components, which are intended to be covered by the door (110), such as the memory card opening, the connecting jack portion (108), and the control button portion (105). Thus, material and manufacturing costs can be reduced, and the degree of freedom in design of the door can be increased.

A drive mechanism for food handling, food processing and cleaning equipment incorporating a rotating barrel. The barrel can have mounted therein a plurality of shafts (8) aligned with their longitudinal axes parallel to the longitudinal axis of the barrel. The drive mechanism includes a single motor (7) adapted to drive via a V belt (13) the shafts (8) which are also linked by a timing belt slave (15).

A laminated single faced flute comprises a fluted layer (12) and aprinted facing sheet (14). The fluted layer (12) comprises an embossed layer. The laminated single faced flute only comprises a single embossed layer and a single facing sheet. Accordingly, a high resolution print is not simply provided as a separate layer and adhered to the facing sheet which would thereby results in the three layers. The laminated single faced flute (10) may be used in packaging t prevent damaged products contained therein. In addition, the laminated single faced flute may be used as a holder (20) to hold and retain warm or hot products therein, cups or hot drinks or soup etc. The image is printed on the facing sheet (14) prior to adhering the facing sheet (14) to the embossed web (12). This thereby retains the characteristic of the flute.
摘要:
An intrinsic gauging device for a ferrule type tube fitting (10) of the type having a coupling nut (14), a coupling body (12) and at least one ferrule (32), includes a precisely formed marking on the coupling body that is visually perceptible when the coupling is in a finger tight position, and that is covered or visually imperceptible or otherwise has a predetermined relationship with the coupling nut when the fitting has been initially pulled-up. In a preferred form, the marking is realized as a precision groove (50) or recess machined into a surface of the coupling body. The groove can be made more easily visually perceptible such as by roughening or knurling the surface, or coloring the surface, for example. The groove defines an edge (50b) at a precise position that corresponds to a predetermined axial displacement of the nut relative to the body for initial pull-up. The marking may also be formed with a precise dimension such as an axial length to provide a second edge that corresponds to a predetermined axial displacement of the nut relative to the body beyond initial pull-up for fitting assemblies that are remade.

A harness bracket (10) comprises a first securement member (12) and a second securement member (14). The harness bracket (10) is arranged, in use, to be mounted to a carriage used in harness racing or trotting where the carriage is pulled along by a horse. A harness bracket (10) is mounted on to two shafts extending from the carriage (11) in order to secure a harness therebetween. The second securement member (14) is movable relative to the first securement member (12) in order for the securement means (i.e. a securement plane or the plane of the harness) to move towards an optimal plane for transferring the forces from the horse to the carriage (11) through the shafts (15). Accordingly, as the horse turns out of the line of the wheels (60) of the carriage, the second part (14) of the harness bracket (10) move and pivot to provide a securement plane at an angle to the plane of the wheels.

A fluid flow control valve comprises a body (11) in which is a valve chamber (14) connecting an inlet to an outlet (15) for a source of fluid, with a flexible diaphragm (18) opening or closing the outlet, in use. An open end of the body is closed by a cover (19), and received in the interior of the cover is a cap-like member (32), between which member (32) and the diaphragm (18) is defined a sub-chamber. The sub-chamber communicates with the source of fluid by way of a bleed hole (18a) in the diaphragm (18) and the outlet from the sub-chamber is a passageway through an outlet tube (32) on a flexible front wall (34) of the member (32), this tube extending through an opening in the cover (19) to contact a sealing pad (31) on an arm (29) of a float pivotally mounted on the cover. The position of the outlet from the sub-chamber is thus movable, due to the flexibility of the front wall (34), and this allows water hammer to be reduced/eliminated.
摘要:
A support clamp (10) securable to a motor vehicle crash barrier (1), a barrier assembly and a method of securing a support clamp to a motor vehicle crash barrier. The support clamp of the present invention is securable to a motor vehicle crash barrier, the barrier having an elongate edge running the length of the barrier and at least one corrugation extending transverse to the edge. The clamp comprises a first jaw member (12) having opposing first and second ends, a second jaw member (14) having opposing first and second ends, and a hinge (46), connecting the first ends of the first and second jaw members, such that the first and second jaw members are rotatable about the hinge to open and close said clamp. In use, when the edge of the barrier is placed between the first and second jaw members and the second ends of the jaw members are pressed towards each other, the clamp grips the corrugation of the barrier such that the clamp is rigidly secured to the edge of the barrier without the need for additional fixing means.
