Title: Paint dosage device for program controlled spray painting system
Inventor: ANFINDSEN OLE ARNT
IPC: B05B5/16
Filed: 1992-05-15
Granted: 1999-12-07
Abstract: A paint dosage device is particularly adapted to be mounted in close proximity to a spray gun (P) in a program controlled spray painting installation for dosed paint supply to the spray gun. The device comprises at least two dosage cylinders (SA, SB), each having a regulating piston (PA, PB) connected to regulation means (RA, MA; RB, MB) for setting the paint filling amount of the associated cylinder by controlled adjustment of the departure position of the regulating piston in the cylinder. The regulation means is also adapted for setting the dosage rate of the cylinder when supplying paint to the spray gun, by program controlling the displacement velocity of the regulating piston in the cylinder. A valve assembly (V1, V2, V3, V4) is arranged for connecting the cylinders (SA, SB) alternately to the spray gun (P) and putting the cylinder disconnected from the gun in connection with means for cleansing and paint filling. This paint dosage device is particularly suitable for application in the case the spray gun is provided with high tension electrode (E) for electrostatically charged atomizing of supplied electrically conductive paint. Each regulating piston (PA, PB) of the cylinders is then connected with the regulation means by means of an electrically insulating motion-transferring connection (IA, IB) and each valve (V1, V2, V3, V4) of the valve assembly is made electrically insulating.

Title: Method and apparatus for encoding and decoding an image
Inventor: KIMURA TOMOHIRO
IPC: H04N19/196
Filed: 1996-07-11
Granted: 2000-03-21
Abstract: An image memory outputs a target encoding pixel and a plurality of reference pixels in the vicinity thereof.   A boundary mode determining unit determines a maximum value and a minimum value of the reference pixels, determines an average value of the maximum value and the minimum value, compares the respective reference pixel values with the average value, detects  a boundary in the target encoding pixel and the reference pixels based on comparison results, and detects a pixel distribution state of the reference pixels based on the detected  boundary.    An  adaptive  predictor  calculates  a prediction value  by performing  a  calculation  based  on  a function corresponding to the pixel distribution state and the reference pixels.   A prediction difference calculating unit determines a difference value between the prediction value and a value of the target encoding pixel.  A prediction coincidence determining unit compares the prediction value and the target encoding pixel value, and outputs a comparison result as a binary signal.  A context generator generates a context based on the pixel distribution state and the difference value of the prediction difference calculating unit.  An arithmetic encoder encodes the binary signal based on the context thus generated.

Abstract: An apparatus for accommodating level placement of a portable building on a support surface includes a foundation leg movable relative to the building and adjustable from inside the building. The length of the foundation leg which extends below the building to the support surface is determined by selectively engaging a bracket in slots in the foundation leg. An adjusting plate is coupled to the bracket and a threaded member is coupled with the adjusting plate. When the bracket engages a slot, the threaded member may be manually adjusted to raise and lower the foundation leg. A portable building adapted for level placement on a support surface may include a plurality of foundation legs and a corresponding number of locking devices for raising and lowering the foundation legs relative to the floor of the building. Each locking device includes a bracket, an adjusting plate and a manually operable member coupled with the adjusting plate.      The building may be set or adjusted by moving one of the foundation legs in relatively large increments to a position which approximates a level condition for the building. Further movement in relatively large increments is prevented by securing the bracket in the slots of the foundation leg. Then, the leg may be moved in relatively small increments to obtain a level condition for the building by adjusting the manually operable member to either raise or lower the foundation leg by the desired amount.

Title: Cooling fluid container
Inventor: STANLEY ERIC
IPC: A01K1/015
Filed: 1995-09-18
Granted: 2005-04-26
Abstract: The invention is a cooling pillow container insert (10) which provides a continuous cool pillow surface and absorbs a pillow user's lost metabolic heat. Preventing thermal discomfort which causes pillow flipping and tossing and turning is the primary goal of the invention. The container (10) slides between a conventional pillow (12) and pillow case (11). The container (10) is composed of a soft vinyl bag (13) which snugly surrounds a fluid saturated porous foam core (15). A resealable valve (29) allows fluid to be added or removed at will and the container's temperature to be adjusted. The container (10) promotes heat transfer from the pillow user (60) to the container (10). The heat is then dispersed uniformly throughout the container's fluid ensuring a uniformly cool pillow surface. Heat is also continuously lost to the surrounding environment. A pillow user's sleep is enhanced in warm temperatures without using an energy source. The container insert (10) can also be used with or without a pillow, as a cooling bed for an animal or a pet (71).

Abstract: A removal resistant closure (32) and container assembly is provided. The container (30) defines an opening. The closure is applied to the container to occlude the opening. A first thread (51) is defined by the container and extends at least partially around the opening from a leading end (A) to a trailing end (C). A second thread (52) is defined by the closure and extends at least partially around the closure from a leading end (A) to a trailing end (C). A projection (C on 53) is defined adjacent one of the first and second threads. The projection (C on 53) and the one thread (e.g., 51) define a space between them which is less than the width of the other (52) of the threads. Either the projection (C on 53) or the other thread (52), or both, are resilient to accommodate deformation during relative rotational movement of the container and closure. When the closure and container are screwed together, the threads are relatively axially displaced from a threadingly engaged condition to a disengaged condition which resists re-engagement.
