IPC: G11B20/10
Filed: 1988-04-29
Abstract: In a reproduction system for use in reproducing a still image from a sequence of predictive error signals which is read out of a memory and which is preliminarily processed into a sequence of preliminary processed signals, an intermediate circuit (31) interrupts the preliminary processed signals in response to an external command signal. In the intermediate circuit, the external command signal is resampled by a sequence of frame pulses in a resampling circuit (34) into a resampled signal so as to close a gate circuit (35). No predictive error signal is sent to an adder circuit (18) during absence of the gate circuit. An identical error signal is repeatedly produced as a sequence of reproduced signals to reproduce the still image.

Abstract: In order to compensate for frequency deviation without using a pilot signal and associated apparatus, a channel number identification code is added to a transmit signal at an earth station transmitter. Each channel unit (demodulator) of a receiving earth station is arranged to extract a channel identification code from a received signal and to compare this with a preset code assigned to that channel. In the event that the recieved channel idenfication code does not coincide with that of the instant channel, the channel determines the number of channels by which deviation which has occured and adjusts its receiving frequency accordingly.

Abstract: The invention relates to a method of manufacturing a gap pot made of fibre composite for electric or magnetic drive units, having a connection flange and a flattened, arched base which is reinforced with respect to the cylindrical part of the gap pot. The jacket of the gap pot is wound from layers of circumferential and helical windings. For manufacturing the pot base, a winding mandrel is employed in which at least one end-face end (pole cap) has a contour corresponding to the inner contour of the pot base; the fibres for the helix windings are guided radially around the pole cap of the winding mandrel, being placed against the pins. After the removal of the winding mandrel, a reinforcing and sealing cap, the edge of which reaches down to the cylindrical part of the pot, is bonded into the pot base. <IMAGE>

Abstract: A latching apparatus is provided for an electrical connector (10) of the tupe having a housing (12) including a plurality of electrical contacts therein. The latching apparatus comprises a deflectable arm (16) that is pivotally supported on the connector housing (12), the pivot being disposed generally between the two ends (16a, 16b) of the pivotal arm (16) such that both opposed ends (16a, 16b) of such arm may move relatively toward and away from the connector housing (12). The front end (16a) of the deflectable arm (16) is provided with a latch for attachment to a complementary latch (42) of a mateable electrical connector or the like. A slidable locking bar (20) is captively supported on the housing (12) for movement between a first position and a second position. The locking bar (20) and deflectable arm (16) include cooperative locking means (30) disposed on both sides of the pivot that are operative in the first position to prevent movement of both ends of the latching arm (16) and in the second position to permit free movement of both arm ends (16a, 16b). As such, when the bar (20) is in the first position, secured locking engagement of the latch is provided when attached to the mateable connector, while when the locking bar (20) is in the second position, the free movement of the deflectable arm (16) permits ease of attachment to or detachment from the mateable connector.

IPC: B24D11/00

Abstract: This invention relates to erodable agglomerates containing abrasive grains, and, more particularly to abrasive products containing the erodable agglomerates. 
     Conventional coated abrasives typically consist of a single layer of abrasive grain adhered to a backing. It has been found that only up to about 15% of the grains in the layer are actually utilized in removing any of the workpiece. It follows then that about 85% of the grains in the layer are wasted. Furthermore, the backing, one of the more expensive components of the coated abrasive, must also be disposed of before the end of its useful life. 
     To overcome this problem of waste, many attempts have been made to distribute the abrasive grains on the backing in such a manner so that a higher percentage of abrasive grains can be utilized, thus leading to extended life of the coated abrasive product. The extended life further leads to fewer belt or disc changes by the operators, thereby saving time and reducing labor costs. It is apparent that merely depositing a thick layer of abrasive grains on the backing will not solve the problem, because the grains lying below the topmost grains are not likely to be used. 
     This invention provides erodable agglomerates containing individual abrasive grains disposed in an erodable matrix comprising hollow bodies and a binder. The agglomerates are useful for coated abrasives and bonded abrasives. Abrasive products containing the agglomerates provide higher stock removal than abrasive products bearing a single layer of abrasive grains, since the erodable character of the agglomerates allows the sloughing off of spent individual abrasive grains during abrading operations and the exposing of new abrasive grains to the workpiece. The invention also provides a method of preparing the agglomerates of this invention.

Abstract: A drive method for a color CRT in which a point­sequential color video signal is produced to drive a modulation electrode of the CRT, in which an index signal (220) is generated consisting of pulses at a frequency identical to a frequency of scanning successive screen phosphor color trios of the CRT, multi-phase index signals (220A, 220B) are derived from that index signal, and respective time differences (t₁,....) between scanning timings of each color trio in each scan line and a specific index signal phase are successively measured, stored in memory, and subsequently read out to produce timing control signals for gating the color components of the point-sequential video signal. Requirements for timing accuracy and assembly precision of the CRT can thereby be substantially relaxed by comparison with a prior art single-phase index signal method.

Abstract: The ski has a device to enhance safety, which is fixed to the upper side of the ski between the tip and the binding. The device (8) has a semi-shell-shaped body with a closed-surface shell wall (22), which widens from a tip (16) to an open end surface (18), and is fixed to the upper side (2) of the ski (4) in such a way that the lower edge (26) of the body rests on the upper side (2) of the ski (4) at least virtually without a gap. In the region of its open end surface (18), the body at least partially overlaps the parts of the ski binding which are at the front in the travelling direction of the ski. By means of the device, due to the large extent of covering of edges of the ski binding which tend to cause injuries, the risk of injury is considerably reduced and, moreover, the ski is given an attractive appearance. <IMAGE>
