Abstract: A sharpening device, for the saw chain of a motor chain saw, with a holding device for a sharpening element which is arranged in the region of the reversing radius and is curved approximately concavely with respect to the center of this reversing radius. The sharpening element is seated upon an adjustment lever which is pivotable in a direction toward the saw chain. This lever cooperates with a screw device which determines the feed path of the sharpening element. An actuating handle is provided for the feeding of the sharpening element; this handle is arranged on that side of the housing of the chain saw located remote from the free reversing end of the guide bar of the saw chain. The actuating handle is preferably releasably secured in the grasping range of the front handle of the chain saw. The actuating handle is connected by a yieldable shaft with a threaded bolt associated with the feeding device, and the nut piece of the threaded bolt is seated in an extension of a support plate connected with the guide bar, that end segment of the threaded bolt which projects freely from the nut piece pressing against an adjustment lever pivotally journalled on the support plate. The adjustment lever supports the sharpening element and is spring biased, with the spring endeavoring to pivot the adjustment lever, together with the sharpening element, in a radial direction against the axis of the reversing chain gear.

Abstract: The invention relates to hydrostatic bearings and seeks to provide a bearing design which affords a reduced consumption of pressure medium without increased risk of bearing breakdown as a result of inlet path blockage. According to the invention an hydrostatic bearing comprises a bearing portion (1) provided with bearing pockets (6), and a mounted portion (2) with a bearing surface (3). Pressure medium is supplied through an inlet duct (7), which extends towards the bearing surface (3) of the mounted portion (2). The end faces (10) of the inlet duct (7) and the corresponding surface (3<1>) of the mounted portion (2) form an annular throttle gap (11). A choke valve (12) may be mounted in series with the throttle gap (11) in the inlet duct (7). Because of the throttle gap (11), the effective cross section of the inlet duct (7) or choke valve (12) if used, can be made larger, thus reducing the risk of blockage of the inlet path. The annular throttle gap (11) is self-cleaning, since it consists of two parts (1) and (2) moving relative to each other. <IMAGE>

Abstract: In order to obtain a reduction of the bit rate when digitizing a color video signal using a picture transform, the color video signal is sampled with a frequency which is twice the color auxiliary carrier frequency. The video signal samples thus obtained are assembled into two-dimensional subpictures each comprising P consecutive video signal samples of each time Q consecutive line signals. Each subpicture can be considered as the sum of a series of superposed basic pictures, each having its own coefficient (which is a weighting factor representing the contribution of the basic picture in the subpicture). Each coefficient is encoded with a number of bits assigned thereto. The basic pictures are assembled from picture squares which are either of a first type (completely white) or a second type (completely black). The Hadamard matrix transform determines the basic picture patterns. Each of the two color information signals u(t) and v(t) in the color video signal now contributes to a subpicture in such a way that this contribution can be fully described by one basic picture. Only the coefficients associated with these basic pictures need not be encoded accurately.

Abstract: A variable gain control system for a digital signal is provided in which the digital signal addresses a digital memory to produce an output signal representative of the addressing signal modified by a transfer characteristic. A control word M is repetitively loaded into an M counter, which counts to a predetermined limit to produce output pulses when the limit is reached. The output pulses increment a data counter. Concurrently, an N control word is repetitively loaded into an N counter, which also counts to a predetermined limit to produce output pulses when that limit is reached. The output pulses of the N counter increment an address counter. When the count of the address counter changes, the current value of the data counter is loaded into a digital memory at the address provided by the address counter. The memory is loaded in this manner to store a data array representative of a signal gain related to the ratio of the N to M.
