Patent CA-1102983-A (CA)

Granted: 1981-06-16
Abstract: ABSTRACT OF THE DISCLOSURE     Composite panelling of upper and lower metal skins with side configuration for interlocking and a rigid foam core are continuously made by feeding separate upper and lower skin panels secured together by preassembled rigid foam end dams continuously past a foam station having a small height mixing head mounted on cross slides to lay down a zigzag pattern of foam between the skins, with the first and last transverse run of foam being parallel to the ends of the skins.  A mixing head is such that valves are located within the head so that the two foamable chemicals do not contact each other until they are fed into the mixing chamber wherein a mechanical mixer mixes them immediately prior to being deposited, which mechanical mixer and valves are of minimum height and fully insertable within the molding space between the skins.  A drive motor for the mixer is located in the main body supporting the mixing head, which main body does not enter into the mold cavity.  The valves and cross slide are operated auto-matically, and if there is too long a delay between foam deposits, the chemical valve faces, mixing chamber, mechanical mixer and other parts exposed to the mixed chemicals will automatically be flushed with a solvent and air.

Abstract: ABSTRACT OF THE DISCLOSURE           A method and an apparatus are disclosed for charging particulate coal through ceiling holes into a coke oven.  A conveyor above the coke oven ceiling is connected with each ceiling hole by a conduit.  Mounted in the conduit is a first closure member which is movable to and from a position in which it permits gravity flow of coal from the conveyor to the ceiling hole.  Also mounted in the conduit is a second closure member movable to and from a position in which it blocks the escape of gas from the ceiling hole.  To charge, the second member is first moved to open position and thereupon the first member; when charging is completed the members are moved in reversed sequence to their closing positions.

Abstract: TITLE OF THE INVENTION          METHOD AND APPARATUS IN THE FABRIC FILTER CONTROL          OF AIR POLLUTION            ABSTRACT OF THE DISCLOSURE         Method and apparatus for maintaining the permeability of porous filtering media used in filtering gaseous suspensions.          More particularly the invention defines Inside Bag Dust Collection wherein high energy pressurized gas is introduced for cleaning the filtering media.  In the method and apparatus pneumatic impulse forces, derived from a series of charges of pressurized gas are directed downwardly through ever open venturi means and away from the interior of the filter bags; specific jet nozzle elements optimize the efficiency of the pressurized gas application, and an induced air funnel means within the bag causes vertical force resolution for induced air cleaning flow.  Spoiler means are provided within jet nozzle means such that particulate matter will neither enter nor accumulate in the jet nozzle opening during normal, onstream gas flow conditions.  There is also an accommodation to the conventional dirty gas chamber to efficiently receive high velocity, high volume induced air cleaning flow.

Abstract: METHOD AND APPARATUS FOR AUTOMATICALLY INSERTING AN ELECTRICAL CONTACT INTO AN       ELECTRICAL CONNECTOR                      ABSTRACT Two embodiments of apparatus and method for automatically inserting electrical contacts into an electrical connector (31) are disclosed.  Each electrical contact (14) is of the type having a retaining shoulder (21) and the electrical connector is of the type adapted to retain the contacts in cavities (62) formed in the connector.  The apparatus includes a vibrating bowl (12, 112) which orients the contacts by vibrating and releases the oriented contacts one at a time.  In the first embodi-ment, a rotary indexer (26), having a plurality of contact receiving passages (40) formed about its outer periphery, receives the oriented contacts, rotates about its axis (27) and releases the reoriented contacts into a plastic trans-fer tube (52),  A slide unit (28) allows the contacts one at a time into a lower part (55) of the tube and into an air chamber (29) at a loading position.  A regulated air supply (30) propels the contacts within the tube, the tube guiding the contacts from the loading position to an un-loading position adjacent the connector and into the connec-tor.  The connector is supported on a base member (64) of an X-Y table (32) to move in two directions so that the cavities of the connector are successively aligned with the tube at the unloading position so that each contact is propelled into its corresponding cavity and retained there-in,  In the, second embodiment, a slide member (160) is slid-ably supported in a housing (142) to move the contacts from a contact receiving position to a contact loading position aligned with plastic tubing (190).  At the contact loading position the contacts are propelled into the taking by an air pressure force.
