Granted: 1985-05-21
Abstract: ABSTRACT OF THE DISCLOSURE     The invention relates to novel electrical devices which are useful for example as heaters and temperature sensors, and which comprise at least two electrodes, at least one PTC element, at least one relatively constant wattage element, and at least one current-directing element which directs the current, when the device is first connected to a source of electrical power, so that the effective initial resistance of the device is greater than it would be in the absence of said element.  Thus the invention provides a solution to the problem of current inrush in application of PTC devices in which substantial current passes through the device at operating temperatures.  The invention also includes the use of the novel devices in application in which current inrush is not a problem.

Abstract: - i -IMAGE PROCESSING METHOD USING A BLOCK            OVERLAP TRANSFORMATION PROCEDURE                 Abstract of the Disclosure An image processing method is provided for reducing noise in a sampled image, particularly for reducing noise in an image divided into blocks of sampled image elements that are transformed by a linear procedure, such as the Walsh-Hadamard transform, and improved regarding visible noise by non-linear thresholding of the transform coefficients.  By operating the process in a hierarchy of stages, each stage employing a block operating on image signals derived from a preceding stage, and by overlapping the blocks processed in each stage, the processed signal from each image element is the linear combination of many transform coefficients from each stage and from each overlapped block within each stage.  Such a large number of contributions making up each processed image element assures that the processed image is generated without a characteristic block-like structure due to block transform processing while the wanted components of the image are rendered with minimal image loss or distortion.

Abstract: HOSE-END ASPIRATOR SPRAYER                        Abstract A hose-end  sprayer includes a linearly actu-ated valve such as a poppet valve that is opened by means of pressure applied thereto from a pivoted lever.  The lever and valve provide instant on and off action and one-handed control over the water flow.          Pressurized water containing a mixed chemical is supplied to a spray defining nozzle in a closed system that maintains the water under full pressure until after it emerges from the nozzle.  By preventing contact between the water and air until the spray pattern is formed, better definition of the pattern is obtained and nozzle drip is eliminated.

Abstract: CAP PRINTER AND METHOD FOR SILK SCREEN PRINTING ONTO THE FRONT PANEL OF A CAP                    ABSTRACT          A silk screen printing device   has a saddle     secured to a frame for mounting a cap     for printing. The saddle has a flat printing plate      which supports the front panel of the cap and is further designed to provide interior supports          to the cap thereby blocking it.  This blocking prevents creases along the front panel and serves to maintain the cap in position during printing.  The mounting of the cap in the same position upon the saddle each time is provided by a registration plate      which is secured to the frame in a spaced-apart perpendicular relationship to the printing plate and defines a channel      between the printing surface and the plates for receiving the sweatband      of the cap. Also connected to the frame is a silk screen within a silk screen frame      which is adapted to move between an advanced position wherein the silk screen contacts the front panel of the cap which is mounted upon the saddle and a retracted position wherein the silk screen is withdrawn for changing caps.

Abstract: ADAPTIVE ECHO CANCELLING SYSTEM AND METHOD                 UTILIZING LINEAR CODE SPACING                            BY                      JOHN F. O'NEILL     Abstract of the Disclosure An improved adaptive echo cancelling system and method is disclosed.  The system and method utilizes linear code spacing and is particularly well suited for echo cancellation of full scale signals.  Echo cancellation is effected by use of digital-to-analog converters functioning as a multiplier receiving first digital signals representative of a received speech waveform signal and second digital signals representative of the termination network on the line, which termination network causes and defines an echo reflection of the received signal.  The output of the multiplier is summed and the sum is then subtracted from the echo components of the received signal to thus achieve echo cancellation and to produce an error signal that is utilized to continuously reduce error between the actual and estimated echo waveforms.  Provision is made to inhibit error indications due to circuit generated coding noise and/or predetermined small detected errors to thereby enhance system operation.

Abstract: Abstract Inside the enclosing wall (1) of the electro-static coating plant for applying dry or wet color coatings to electrically conductive surfaces of articles (2) set up in an insulated position is located an electrostatically changeable curtain (9), the charge polarity of which is the same as that of the spraying gun (7) used for the coating operation.  The article (2) set up in an insulated position is supplied with opposite polarity, which is necessary for the electrostatic coat-ing, by an inductor arrangement (16) arranged above the article (2), the inductor arrangement (16) applying an electrostatic field produced by means of a peak inductor (19) to an electrically conducting layer (18), which is located on the rear of a casing piece (17) made of insulating material.  The charge field radiated from the surface of the casing piece (17) brings the article (2) to be coated, suspended beneath the casing piece (17), to a potential at which the material particles located in the spraying jet (8) of the spraying gun (7) strike both the front and rear surface sections with approximate-ly uniform distribution.        The achieved electrostatic guidance of the coat-ing material particles enables both an optimum utilization of the coating material and a speeded-up operating function of the coating plant.

The die plate can be removed for replacement with another die plate, or for addition or substitution of die plate sections which conveniently alter the message otherwise printed by the die plate.  The elastomeric extensibility of the retainers permits expansion of the die plate (or replacement with a larger die plate) without necessitating use of a larger or different mounting member.  Also, when the die plate becomes substantially oversized relative the die plate mounting member, the elastomeric retainers permit the die plate mounting member to be rocked by means of the handle to distribute pressure more evenly over the back of the die plate to ensure that a proper image is received for example on a sheet of paper.  The mounting member also includes holders for releasable securing the retainers to the mounting member, and so arranged that the mounting member can be oriented with either its lengthwise or widthwise axis along a given axis of the die plate.

Abstract: ABSTRACT      A thread form for a tubular connection of the type having a pin member (13) adapted to be made up with a box member (15) to form a pipe joint is shown.          The pin member (13) has pin threads with thread crests (17) and thread roots (19) which are adapted to be made up with a mating box member (15) having a complimentary thread structure. The pin thread crests (17) are formed between a stab flank (21) and a load flank (23) of the pin thread. The pin thread has a chevron-shaped load flank (23) for engaging a mating chevron-shaped load flank (25) of the complimentary box member (15) to provide a chevron type interfit between the load bearing load flanks of the pin and box threads. The pin and box threads are also helically structured as a wedge.          The chevron type interfit serves to limit the radial movement of the pin threads into the mating box member complimentary thread structure to control the radial make up of the pipe joint.    (Fig. 4)
