Abstract: ABSTRACT      A procedure for generating a mirror image of a graphic object on an interactive computer graphics display is disclosed.  In the specific example described, a cursor locating device such as a mouse and an all points addressable display are assumed.  The graphics object for which the mirror image is to be generated is selected by means of the pointing cursor.  The mirror image function is also selected by means of the pointing cursor.  This causes a default mirror image to be generated on the display along with the original image of the selected graphics object.  In addition, a "mirror" with a direction handle and an angle handle is diplayed in a window on the display. Either of these handles may be "grabbed" by selecting with the pointing cursor and then rotated to manipulate the generated mirror image and the selected object on the display.  When the direction handle is rotated, the generated mirror image and the selected object are simultaneously rotated in the plane of the display.  When the angle handle is rotated, the generated mirror image and the selected object are simultaneously stretched or shrunk depending on the direction of rotation to provide a "butterfly" effect.

Abstract: ABSTRACT OF THE  DISCLOSURE            Apparatus for suppressing intersymbol interference and improving the signal-to-noise ratio in a digital line amplifier includes a filter with a fixed transfer function that couples equalized digital signals to a first differential input of a difference amplifier and substantially filters out high frequency random noise present in the signals to achieve signal-to-noise enhancement with consequent degradation of the signals by intersymbol interference.   Subsequently, an output from the amplifier is sampled by a quantizer that produces a bit stream output of portions of the enhanced signals, excluding the intersymbol interference.   Signals from the bit stream are then coupled to a fixed coefficient decision feedback equalizer having the same transfer function as the filter and are output therefrom as feedback signals to a second differential input of the amplifier such that the signals at both differential inputs are substantially equal in terms of intersymbol interference, thereby suppressing such interference in the amplifier output.

Abstract: A coating is placed on a micro-porous carrier in the presence of a volatile liquid which is able to migrate the coating into the carrier and to desolvatise the coating. The liquid is subsequently volatilised and the resulting dry ultra-filtration membrane is essentially crack-free and has desirable mechanical and chemical stability. The carrier may be pre-treated with a volatile liquid such as acetone before the coating is placed on the carrier. The carrier material may alternatively be dispersed in a volatile liquid such as methanol for the formation of a coating suspension which is placed on the carrier. The coating material, preferably zirconium oxide will have a particle size in the interval from approximately 5 mμm to approximately 10 μm, and the coating will have a thickness of up to approximately 20 μm. The carrier, such as a porous carbon tube will have a pore volume of approximately 5-60 per cent and a pore size of approximately 5 mμm - 40 μm. The stability is increased by burning the membrane at 25 degrees centigrade to 1,500 degrees centigrade, preferably at approximately 400-600 degrees centigrade.

Abstract: A camera (18) arranged in the axis of a bottle to be tested is used to take pictures in order to determine defects in the upper end face of the mouth lip (43). A circular, coaxial light-conducting body (30) which is surrounded by a light source (28) is arranged between the lip (43) and the camera (18). It has a central viewing opening (40) with the shape of a double conical frustum (40a, 40b). The cylindrical surface of the conical frustum (40a) facing the lip forms a light exit surface (46a) for illuminating the lip (43). The angle of slope of the conical frustum (40a) is selected such that an annular optical conical frustum (52) falls onto the upper end face of the lip (43) and has in the middle thereof an angle of incidence of approximately 45 DEG . This yields a dark field illumination of the lip (43). Should a defect be present in the region of the upper end face of the lip (43), it becomes visible brightly on the dark background. Lateral defects of the lip (43) can also be determined with the aid of an additional light-conducting body (34).

Abstract: In radio communications receivers for use on frequency hopping radio communications networks, the received signal in each hop period is analyzed and assigned a quality value. If more than one signal is present during the hop period it is determined that more than one network has changed to the same frequency. Similarly if the received signal is out of synchronism it is determined that more than one network has changed to the same frequency. When more than one network has changed to the same frequency, the received signal is not output by the receiver but is replaced by an earlier (or later) received signal.

Abstract: Instrument for measuring the distances of points from a plane or a straight line defined by means of the instrument. The instrument may also be used in marking out points on a plane or a straight line.The instrument functions by forming at least two mirror images (1, 2) of a measuring object (7) in such a manner that these images are differently oriented when viewed. This is accomplished in the simplest embodiment of the instrument by means of a prism 8 whose front face (6) is semi-reflecting whereas the other faces (4, 5) are perpendicular to each other and totally reflecting. If the measuring object is not on the defined plane or line (10) this will show up as a displacement of the differently oriented mirror images in relation to each other.The substantial novelty of the instrument is that all the images the relative displacement of which are employed for the read-out are mirror images of the measuring object and are formed without the need for focussing optical components such as lenses and concave mirrors.

Abstract: A joint (10) and male and female tubular element (30, 20) where the threads (70, 80) of the female and male members (20, 30) have negative load flanks (44) and have two or more radial steps axially separated one from another by a reverse angle torque shoulder (43) having one or two adjacent conical sealing surfaces (41, 42). The reverse angle torque shoulder (43) produces radial positional interference of the conical sealing surfaces (41, 42) when the male and female members (30, 20) are fully assembled and serves as a positive assembly stop. The negative load flank angle of the threads and the reverse angle torque shoulder combine to interlock the male and female members and to prevent differential radial separation of the conical sealing surfaces when the joint (10) is exposed to internal pressure, external pressure or both. Tapered threads and sealing surfaces and interference threads may advantageously be used in joint construction.

Abstract: A ring encircles produce placed on a work table. Tie ribbon is fed by pressure rollers around the inner periphery of the ring to form a complete loop. A first gripper clamps and retains the free end of the ribbon against a second gripper. The pressure rollers operate in reverse retracting excess ribbon about the produce. A friction clutch, operative only for reverse ribbon feeding, allows for ribbon slippage as the ribbon tightens around the produce. Then the second gripper clamps the other end of the ribbon against a twister head and a twister mechanism rotates the clamped ends of the ribbon about a common axis twisting the ribbon ends together. Shearing edges sever the engaged ribbon from a ribbon supply during twisting. The grippers and twister mechanism are at ends of concentric support rods and tubes, and the grippers in clamping move along the rotational axis of the twister mechanism. Axial gripper motion is provided by cylinder valves having pistons concentric with and supported by the gripper support rod or tube and acting, respectively at the ends of the gripper supports away from the tie ribbon. Rack and pinion mechanisms provide rotation of the twister mechanism and forward and reverse feeding of the ribbon. All components are pneumatically driven. The design accommodates normal wear and temperature variations without adjustment.
