Abstract: A digital servo control system for a data recording disk file receives as input a digital head position error signal (PES) and a digital signal corresponding to the head actuator input signal, and outputs a digital control signal. The control signal is integrated and amplified to provide the input signal to the actuator. The control signal is calculated from estimated values of absolute head position, head velocity and the equivalent actuator input signal required to compensate for constant or very low frequency bias forces. The estimated values are functions of respective predicted values, which in turn are functions of, among other things, constants representing the digital sampling time and physical parameters of the actuator. The updating of the estimated values from the respective predicted values is made with the use of an error term, which is the error between the measured absolute head position and the predicted absolute head position. The predicted absolute head position is made sufficiently accurate, that the error term is always less than a selected number of tracks. This permits the digital servo control system to operate during track seeking without counting track crossings so that the system is operable with servo information recorded either in sectors on a data disk or in continuous tracks on a dedicated servo disk.

Abstract: A line is provided for assembling a product including proteinaceous patties having a filling therebetween. All components of the line are mechanically synchronized to maintain a consistent pitch throughout the assembling procedure. Included is a patty forming means (14) that deposits proteinaceous patties such as ground meat patties (27) onto a moving conveyor assembly (11) to thereby define the desired pitch.

Abstract: As used in a digital television receiver the invention includes a first phase locked loop which develops a sampling clock signal (CK) that is locked to the horizontal line synchronizing signals components of a composite video signal. A second digital phase locked loop is clocked by the sampling clock signal and develops a digital signal that is phase locked to the color burst signal. This signal is used as a regenerated color subcarrier signal to synchronously demodulate the chrominance components of the composite video signal into I and Q color difference signals. To compensate for frequency instabilities in the regenerated subcarrier signal caused by frequency instabilities in the line-locked clock signal, a third digital phase locked loop (300) develops an oscillatory signal (from oscillator 302) which is phase locked to a reference signal generated by a crystal controlled oscillator (310). A control signal (Cʹ) from the third phase locked loop is applied to circuitry (329, 338) which develops a control signal (Cʺ) that is independent of the crystal frequency. This control signal is applied to modifying means (328) in the second phase locked loop to substantially compensate for frequency instabilities related to the clock signal. Since the control signal applied to the second phase locked loop is independent of the frequency of the control, there is no need for manual adjustment of the crystal oscillator.

Abstract: The intermittent straightening of the wire (1) is carried out by means of a fixedly supported straightening rotor (4), the straightening blocks (5, 6, 7) of which radially deflect the wire (1) advanced by conveying mechanism (2). The mass moment of inertia of the straightening rotor (4) is dimensioned to be so small that the straightening rotor (4) can be decelerated and accelerated at least approximately within the same time period as the wire (1) by the conveying mechanism (2). For cutting to length, the straightening rotor (4) is braked in synchronism with the wire (1) and thereafter again accelerated. Thereby, a perfect wire quality is achieved, in particular a uniform elongation approximately constant over the entire length of the wire, without having to move the cutting device at the high wire feeding speed, or without having to move the straightening rotor axially or the straightening blocks radially, in order to avoid heating up and damaging of the arrested wire by the further operating straightening rotor. Different straightening rotors (4) are utilized for different wire types, these rotors being easily exchangeable with their bearings (46).

Abstract: Each user of an intercommunication bus is associated with a distinct channel of an arbitration bus and maintains a priority record indicating its current priority status against each other user. During a contention interval each user then seeking to use the intercommunication bus bids for use of it by transmitting a bus request signal and makes an analysis of the signals to ascertain if it has a dominating priority for initiating a transaction on the bus, and access is granted accordingly. During the use-signal interval a user then using the intercommunication bus transmits an in-use signal used to update priority records with the effect of giving the last using user lowest priority. For transactions which require a response from a user other than the one initiating the transaction, a second round of bidding is conducted to determine whether any user is qualified to respond and if so which will be enabled to do so. When the response bidding shows no bidders the system immediately initiates bidding for a new transaction.
