Abstract: A paint gun assembly comprises two connected body parts, the spray head 1 and the connecting manifold 2. The spray head is provided with a bore which terminates in a radially extending space 3 of gradually increasing radius. Received in the bore is a shaft 4. The shaft has an axially extending bore which connects with radially extending bores in which balls 5 are contained. Received in the shaft is a plunger 6 which has a rounded end and which engages with the balls 5. When forced into the axial bore, the plunger 6 forces the balls 5 into the radially extending bores and out into the tapered, radially extending space 3. Engaging with the plunger 6 in the manifold body 2 is a cam 7.  The cam body 7 is exposed at a surface of the manifold body 2 and includes a hexagon drive 8 by means of which the angular rotation of the cam can be adjusted using a suitable key. The manifold body further includes a recess 9 for receiving a retaining pin (not shown). The end of the retaining pin is received in the cam guide profile 10. Axial movement of the cam 7 in its housing is further resisted by compression spring 11.

Inventor: JANSSEN JOZEF JOHANNES MARIA
IPC: A61C17/02
Filed: 2009-11-13
Abstract: The cleaning apparatus includes a source of gas under pressure (12) and a source of fluid (14), along with associated gas (26) and fluid (34) chambers, adapted for successive single uses. A user-operated metered valve (22) connects the gas reservoir to the gas chamber, while a liquid pump (30) and a one-way valve (32) connects the liquid reservoir to the liquid chamber. When gas is released from the gas reservoir, it expands rapidly from the valve into the gas chamber, resulting in pressure therein sufficient to open a one-way valve (34) connecting the gas chamber to the liquid chamber. The gas in the liquid chamber forces liquid therein through a liquid line (15) to a connecting point with a gas stream line (13) from the gas chamber. The interaction of the fluid with the gas stream results in a spray of liquid droplets (17) which are directed out of the gas stream line exit orifice (16) to the teeth for cleaning.

IPC: F23H13/00
Filed: 2011-10-25
Abstract: A combustion device in the form of an elevated fixed-grate that includes arcuately shaped solid refractory brick with ribs placed thereunder so as to allow horizontal air flow for fuel combustion. The brick are arranged atop one another in a stacked concentric configuration that forms a central fuel passageway and allows cascading of a fuel pile throughout the combustion stages. The device provides the benefit of proper de-ashing online while distributing the underfire air radially around the fuel pile. The elevated design of the bricks allows the air to be evenly distributed throughout the fuel pile and further allows the isolation of overfire and underfire air. Segregating overfire and underfire air in an evenly distributed manner allows the burner to combust a wide range of fuel moisture contents without modifying the mechanical components of the burner.

Abstract: A high definition television video content management and/or copy protection method and apparatus are achieved by modifying portions of one or more channels of an HDTV  (high definition television) signal. These modifications are generally in the blanking intervals but can extend into the overscanned portions. In one version, the signal modification defines tags or trigger bits for a content control system. This modification may follow the HDTV tri-level sync (synchronization) pulses for example, and it may occur in at least one of the HDTV video channels. In another version, portions of the tri-level sync pulse are modified to cause a reference sensing circuit such an AGC system (in a receiving device such as a video recorder) to produce an erroneous output.  Optionally, a signal may be added or inserted following the modified tri-level sync pulses. In another version, tri-level pseudo sync pulses are added in blanking or overscanned intervals.  These tri-level pseudo sync pulses may be asymmetrical and may be followed by a signal. Further, any of the above modifications or signals or sync signals may be modulated (e.g., amplitude, position, pulse-width). Also provided are defeat methods and apparatus to reduce effects or to modify results of the modification processes.
