  • Patent number: RE32908
    Abstract: A multiple cathode DC arc plasma generator arrangement is used in connection with a single anode for thermal arc plasma processing of materials. A nozzle is provided to introduce a gas in approximately the center of the multiple cathodes, towards the anode. The nozzle injects the gas into the center of the plasma column generated between the cathodes and anode to stabilize such arc and affect the self-induced electrode jets. This provides control of the heat transfer to the anode and permits feeding of particulate matter into the core of the plasma column to enhance inflight processing (melting and/or chemical reaction) of the matter. A set of gas nozzles positioned radially about the anode may be employed for feeding of particulate matter at the anode surface.

  • Patent number: 4821363
    Abstract: In order to achieve satisfactory defrosting without causing undue wear of the wiper blades equipped with double tongues of elastomer material, the invention provides for first freeing the tongues from the coating of ice by blowing hot air into the duct formed between said tongues, then raising the pivot shaft (24) of the blade holder, and therefore the tongues, by applying an axial thrust to said shaft by means of the piston (27) of a jack (86) while retaining parallelism between the tongues and the windshield. The connection, preventing rotation but allowing free axial sliding, between the shaft (24) and the driving connecting rod (29) makes it possible for the shaft to pivot both in the raised position, while passing a current of hot air over the ice from the windshield wiper which has been lifted off the windshield, and in the lowered position in which the tongues bear against the windshield.

The chamber includes an outer housing having a roof portion and an annular side portion. The housing is adapted to cover and be seated on the container. An inner chamber is included which has an annular wall affixed at its top portion to the underside of the roof portion of the outer housing. A fluid entry port is mounted on the side portion of the outer housing facing the annular wall of the inner chamber. The port is for connection to a hose and nozzle for dirt and fluid intake. A float mechanism is mounted on a lower portion of the inner chamber wall and alongside the riser tube.

  • Patent number: 4821368
    Abstract: An eccentric shock isolation grommet assembly is provided in which the centerline of the attachment ferrule is off-set from the centerline of the entire grommet assembly such that the weight of the component to be supported in vibratory isolation deforms the grommet into a generally symmetrical shape and positions the component in the center of the grommet's deformable sway space.

  • Patent number: 4821369
    Abstract: A castor comprises a castor body (12), a castor wheel (14), and a bearing block (20) for supporting the castor wheel relative to the castor body. The bearing block is selectively mountable in each of a first and a second orientation relative to the castor body. In the first orientation of the bearing block relative to the castor body, the castor wheel is arranged to be braked in response to the application of a load applied to the castor. In the second orientation of the bearing block relative to the castor body, the castor wheel is arranged to be braked in the absence of a load applied to the castor.

  • Patent number: 4821370
    Abstract: A single or multiple drapery track and mounting bracket therefor. A cooperating locking latch is provided for mounting the track to the bracket quickly and without using tools. The track has a longitudinal bead along one edge and a dependant wall spaced therefrom. The dependant wall has an outer inclined face having at least one longitudinal notch. The mounting bracket is generally L-shaped, the horizontal leg carrying a downwardly opening curl of size and configuration to receive the bead. The other leg has an inwardly canted strut or tongue of limited resilience. The mounting bracket is first installed on a vertical wall and the longitudinal bead of the support engaged within the curl. The track is pivoted toward the horizontal leg of the bracket forcibly flexing the tongue until it is tightly engaged within the notch. To dismount the track, the tongue is manually flexed until free of the notch and then, the track is pivoted in the reverse direction until free of the bracket.

  • Patent number: 4821371
    Abstract: A safety handle releasably drives a shaft which is also otherwise powered. The shaft has an axis of rotation and a peripheral engagement band. The safety handle has a frame including a bearing aperture receiving shaft so as to be freely rotatable on and relative to the shaft, a lever arm extending away from the bearing aperture, and pivot means laterally spaced from the aperture. Centering means resiliently bi-directionally biases the drive handle and engagement means towards the centralized position. When the drive handle is grasped and twisted around the handle axis, the engagement means is pivoted to engage the engagement band, enabling torque exerted on the drive handle relative to the shaft axis to turn the shaft, but when the twisting effort is released, the centering means returns the handle and the engagement means to the centralized position, thereby releasing the engagement means from the engagement band and freeing the safety handle for free rotation around and relative to the shaft.

  • Patent number: 4821373
    Abstract: There is described a hinged structure comprising two supports and one or more hinges hinging the supports together so that they are parallel and closely adjacent, the or each hinge comprising two hinge members, each hinge member being made of resilient strip material, each hinge member being S-shaped, passing partially round each support and together with the other hinge member forming a letter .chi. or FIG. 8 configuration as seen in a direction along the supports, wherein a releasable catch is provided for holding the supports in a predetermined relative angular position, the catch comprising two cam members each associated with a respective suport and the two being resiliently urged into engagement and so shaped and arranged that rotation away from the said predetermined relative angular position of the supports urges the cam members apart against the resilient urging.
