    • Picture filtering technology generates mathematical mathematical models to represent photographic filters for application to digitized frames of picture stock. A desired filter is determined, and reference pictures, one taken with the filter and one taken without the filter, are selected from a picture library. The selected pictures are digitized and stored. The digitized pictures respectively comprise corresponding sets of pixels or digital data units between which a quantitative differencing is performed. The quantitative difference may be based on any number of variables, such as luminance. When the difference in the luminance values of each corresponding pair of pixels is determined, a mathematical model which is representative of this difference is generated. The mathematical model is essentially a mathematical model of the desired filter, “filtering” digital data in a substantially similar manner in which photographic filters affect light. The mathematical model is then applied to the digitized frame which is to be filtered, thereby modifying the luminance values of the pixels to effect the desired filtering of the image.
    • 图像滤波技术产生数学数学模型来表示应用于图像库数字化帧的照相滤光片。 确定期望的滤波器，并且从图像库中选择参考图像，一个带有滤波器的图像和一个不带滤波器的图像。 所选图像被数字化并存储。 数字化图像分别包括相应的像素集合或数字数据单元，其间执行定量差异。 定量差异可以基于任何数量的变量，例如亮度。 当确定每个对应的像素对的亮度值的差异时，产生代表该差异的数学模型。 数学模型本质上是所需滤波器的数学模型，以基本相似的方式“滤波”数字数据，其中照相滤光片影响光。 然后将数学模型应用于要滤波的数字化帧，从而修改像素的亮度值以实现图像的期望滤波。

    • 1,104,109. Drilling. L. KLEIN. 10 Nov., 1965 [2 Dec., 1964], No. 47722/65. Heading B3C. [Also in Division B5] A clamp for applying hold-down pressure to a workpiece 14 on a working surface 11 during a drilling operation comprises a base mounting member 19 adapted to be attached to the working surface, an elongated pressure beam 24 adjustably mounted on the base mounting member, a gripping block 35 mounted on one end of the pressure beam and having a bore therein for receiving the spindle 36, Fig. 4, of a work clamping assembly 35, a bearing contact sleeve 37 in coaxial surrounding relation to the spindle and disposed between the spindle and the inner surface of the bore 39, a plurality of bearing members 41 carried by the sleeve in circumferentially spaced bearing relation between the spindle and a flared portion 40 of the bore, and resilient means 42 acting between the sleeve and gripping block to bias the flared portion against the bearing members to press them against the spindle. The base mounting member 19 is secured by a screw 22 to the table and carries an upstanding post 20 on which is a clamp 21 for the pressure beams 24. One end of the beam carries the gripping block 35 in which the sleeve 37 is mounted, the sleeve having apertures for locating the bearing members which are in the form of balls 41, a spring 42 acting on the sleeve to urge the balls against the flared portion 40 of the block and against the spindle 36 which is located in the sleeve to lock the spindle in its adjusted position. The lower end of the spindle supports a holddown shoe 49, Fig. 7 (not shown), which is carried by a pin 50 engaging a slot 58 in the bifurcated end of the spindle and can be urged downwardly to engage a workpiece by a lever 48 formed with a cam surface 56 engaging the shoe. In operation, the clamp 21 is released to permit adjustment of the position of the clamping assembly 35 over the workpiece and retightened. The spindle 35 can be moved downwardly by applying pressure to a cap 46 on the upper end of the spindle so that the shoe engages the workpiece, the balls permitting downward movement of the spindle but resisting upward movement until the sleeve 37 is lowered relative to the gripping block. Increased pressure of the shoe against the workpiece may be obtained by deflecting the beam upwardly by pulling the gripping block 35 upwardly as the spindle is pressed downwardly. Still further pressure may be applied by movement of the lever 47 causing the cam surface 56 to press the shoe 49 downwardly relative to the spindle 36. Springs may be disposed in the slots 58 to urge the shoe to its upper position. The sleeve 37 may be moved to release the balls 41 by manual pressure or by a cam acting on a flange 44 of the sleeve. The shoe member may be flat, as shown, or have an inverted V configuration for holding rods, have a pointed shape to effect centring of a workpiece, or have a roller surface for guiding moving material.
