Abstract: This invention relates to window films and more particularly to a low haze colored window film wherein coloration of the window film is effected with a pigment. The invention further is concerned with a process for the manufacture of the pigmented window film. The window film of this invention is pigmented with a pigment having small particle size wherein the particles are coated with a resin binder which encapsulates the pigment particles. The encapsulated pigment particles are blended into an adhesive which is compatible with the resin binder which is used to encapsulate the pigment particles. The resulting adhesive is used to secure one or more film layers of a composite window film structure together. The resulting films have haze levels which approximate the haze levels of dyed window films. The window films of this invention have outstanding light stability.

Abstract: A flow sensor with a tube through which flows a medium to be measured and a housing comprising a lower shell and an upper shell and receiving electronics with unions provided with a flow bore communicating with the tube and which are received in recesses made in facing sides of the lower shell and upper shell, wherein the unions have an outer part, an inner part and a central piece, the inner part of both unions is provided with a blind hole concentric to the flow bore, and in which are mounted the ends of the tube, and the central piece is constructed cylindrically with a reduced diameter compared with the parts of the unions, and the lower shell and upper shell are in each case provided with a semicylindrical portion receiving the central piece of the unions.

Abstract: A pressure compensated plug connector is provided for making an electrical connection under water. The connector includes a plug part provided with contact pins, a socket part having a casing for receiving a plurality of female contacts. A front plate is also included in the connector having a number of openings which correspond to the number of female contacts employed therein. The casing has at least one pressure compensating bore for compensating pressure between an inner space of the casing and the surrounding environment. A membrane separates an outer space communicating with the pressure compensating bore from an inner space filled with a non-conductive fluid surrounding the female contacts.

Abstract: A video camera system employs a standard flood lamp housing enclosing a video camera, an AC powerline encoder, a power supply and a single conductor screw-in type AC electrical fitting. The video camera is surrounded by a plurality of white infrared light emitting diodes for illuminating the environment in front of the video camera in low and no light situations. The AC electrical fitting engages an AC screw-in type receptacle. The video camera captures a video signal. The encoder modulates the video signal upon the AC powerline. A video signal decoder located at a remote location receives the modulated signal over the AC powerline, demodulates the signal and directs its output to a video monitor. The video monitor coupled to an AC outlet common to the powerline scheme in which the video camera is connected displays the captured video signal.

Abstract: In an automated analyzer containing a spectrophotometer for determining color changes in a urine sample the urine is admixed with a basic indicator effecting the first color change and an acidic indicator effecting a second color change, a surfactant and water. The spectrophotometer determines and prints whether a first or second color change has occurred.

Abstract: A water vehicle lift includes a winch which is operable to extend and retract an elongated flexible cable to lower and raise a platform on which a small water vehicle may rest. The winch is preferably mounted on a piling with the platform moving up and down adjacent the piling. On the face of the platform immediately adjacent the piling, a wheel is provided which rolls on the surface of the piling to maintain the platform slightly spaced away from the piling.

Abstract: A center abduction bar attached at opposite ends to T-shaped connecting elements held in place by thumb screws, the connecting elements attached to side plates conforming to the shape of a patient's thigh and a soft covering over the side plates. The center abduction bar has an inner bar and outer tube to permit adjustment of the center bar's width and to control abduction of the patient's knee and hip. A thumb screw on the abduction bar controls the width setting.

Abstract: A disposable manometer includes a chamber connectable to a source of CPR air pressure via a patient breathing valve and an elongated restricted passageway. The manometer includes a dial and a pointer rotatably disposed with respect to the dial to indicate the pressure sensed within a manometer chamber. The pointer has an actuator stem with a spiral-shaped protrusion coupled to a groove within an opening of a stem coupling attached at the center of a diaphragm forming one wall of the manometer chamber. Responsive to pressurized air entering the manometer chamber, the diaphragm reciprocates against the force of a biasing spring moving the stem coupling with respect to the actuator stem for the pointer so that the interaction between the spiral-shaped protrusion and the groove causes rotation of the pointer to indicate the pressure within the manometer chamber. The disposable manometer is intended to be used with a CPR bag or a patient breathing tube.

Abstract: A greeting card picture frame which allows a picture to be easily and quickly mounted. The greeting card picture frame is a unitary integral construction of a decorative border having a filler or block providing a mounting surface for receiving a picture. Double-sided adhesive tape, on the center of the mounting surface, allows a picture to be easily and quickly positioned and secured by pressing it down on the adhesive surface of the tape. A matteboard is then applied that has double-sided adhesive tape securing the picture in the frame. A flat backing having a folding portion approximately equal to the width of the frame provides a self-contained stand or easel. A corner of the folding part is creased to provide a base for displaying the frame and picture on a desk or table top. A mounting hole is also provided in the frame for mounting the picture on a wall and for storing an included push-pin for hanging.
