Abstract: The proposed image-processing method for determining the structural strength of a test object with a diffuse-scattering surface involves: the creation of an interferogram based on radiation back-scattered by the surface of the test object; conversion of the intrerferogram into a modulo-2.pi. image; and the stabilization of the modulo-2.pi. image to form an output grey scale value image. From the later, an identical duplicate grey scale value image is produced; this is then geometrically shifted and modified by applying an invariable grey scale value in the entire image area, before being finally subtracted from the initial grey scale value image to produce a grey scale image containing easily evaluated information on deformities in the observed test object.

Abstract: A projector which projects a flat picture or image in a horizintal plane onto a vertical screen. Because the projection optic used is arranged above one corner of a four cornered picture and can be rotated about a vertical axis the projector can be placed not only on one side of the projected picture, which is thus not obstructed by the projector and it's operator, but alternatively to the either side thereof. The picture can be square or rectangular. The invention can be applied both with overhead projectors and with TV type projectors.

Abstract: A method of obtaining an electric discharge effected by a device for obtang an electric discharge resides in that on the surface of a cathode (3) is formed a layer (4) of oxides from the cathode material and together with an anode (2) made in the form of a hollow cylinder which encompasses the cathode (3) they are installed in a vacuum chamber (1). Equality of impedances is insured at each point on the surface of the anode (2) facing the cathode (3). Then an electric discharge is initiated in the gap between the anode (2) and the cathode (3). The movement and removal of the plasma-forming substance flow from the gap between the anode (2) and the cathode (3) is regulated by means of diaphragms (17, 18).

Abstract: An improved adjustable monitor support assembly is provided that utilizes a plurality of interchangeable side support assemblies and monitor supporting shelf assemblies. Each such shelf assembly is engageable with each pair or side support assemblies. Thus, a particular pair of side support assemblies can be used with either a monitor supporting shelf subassembly structure for a conventional monitor or a monitor supporting shelf subassembly structure for a flat LCD type monitor.

Abstract: A multi-channel readout chip is provided in which each channel has an analog section and a digital section. Each channel of the readout chip employs low noise charge amplifiers with self trigger and calibration capabilities to provide timing information with better than 20 nanosecond precision. The trigger threshold can be adjusted to provide energy discrimination. The chip has a sparse readout function in which only the channels which have received signals greater than a preselected threshold value are readout, thus providing fast data acquisition capabilities.

Abstract: There are a number of devices for washing/recycling thermoplastic. However, the devices tend to be designed on a scale for use at a central site. Additionally, the devices currently available do not have a positive feed travel mechanism. Rather the devices permit the thermoplastic to be "pushed" through at a rate dependent on the feed rate. The present invention provides a compact washer/recycler having a positive feed travel which is designed to shred, wash, dry and compact plastic at the location of its use.

Abstract: A combination of two frames (2) and (4), one inside the other, for positioning a filtering ceiling. The frames have indented splines (3) and (5) on their facing surfaces, and an inflatable tube (6) is anchored on the spline of one of the frames. The tube is inflated to properly position the two frames, to hold the ceiling in place and to seal it so that all air must pass through the filtering ceiling. The tube is deflated to allow the filtering ceiling to be lowered for maintenance or replacement.

Abstract: The present invention relates to debeaking turkey and chick poultry through non-contact thermal transfer from a source of high frequency heat generating radiation. The present invention directs heat onto the upper beak of a live bird by convection or radiation to thereby affect the continued growth of the beak. Such heating of the bird's upper beak provides a debeaking method which allows the bird's upper beak to stay in place for several days allowing the bird to eat and drink. Heating the portion of the upper beak also allows the poultry tongue and lower beak to be shielded from the heat causing less trauma and injury to the bird. The heat may be directed onto the poultry upper beak by radiation or convection.
