Abstract: A flat, flexible film web (2) is drawn off from a stock roll (3), moved over a forming shoulder (12) and thus formed into a tube (20). A longitudinal seam is made on the tube (20), the product to be packed is introduced and the package is sealed by transverse seams (17, 21). The film web (2) is driven continuously by means of drive rollers (7). The longitudinal and transverse seams are produced as the tube is being continuously advanced. A photocell (19) is used to scan printed marks on the film web (2) and a correcting means in the drive of the transverse welding jaws (40, 43) prevents the possibility of inaccuracies in the pack division being added. <IMAGE>

Abstract: Methods and apparatus for accurately measuring propagation delay through very high speed VLSI devices with a test instrument having errors comparable to the delays being measured. The VLSI device has a plurality of parallel operational signal paths, each with a very short propagation delay. The VLSI device is fabricated with control circuitry for selectively connecting the parallel operational signal paths in series in a test mode so as to define a test signal path comprising multiple operational signal paths. The test signal path has a relatively long propagation delay which can be measured with acceptable accuracy by the test instrument. The test signal path is defined so that it bypasses clocked circuit elements on the VLSI device. Since the operational signal paths are on the same integrated circuit and have very well correlated operating characteristics, the propagation delay through the test signal path is a good representation of the integrated circuit dynamic operation. When the integrated circuit is not in the test mode, the series connections are disabled and the parallel circuits operate in their normally intended manner. A minimum of circuitry is added to the VLSI device in order to implement the test mode.

Abstract: An improved fiber glass manufacturing apparatus has an improved fiber glass bushing control system. One aspect of the system has a weighing means for weighing complete collections of glass fiber strands produced from forming from a bushing through attenuation, a monitoring means for the time of attenuation at constant strand speed and a program computer means that receives signals from the weighing means and the monitoring means. The program computer means has a means for establishing a database of the weights and times, a means for determining the throughput of the glass from the bushing from the weights and times, a means for determining average throughputs and including these averages in the database, a means for comparing the average throughputs to a standard set throughput, and a means for initiating an adjustment to the main bushing temperature controller. When the average throughput deviates from the set point throughput by a value greater than the sensitivity factor of the bushing. Also, the improved system has circuit means for carrying the adjustment signals to the controller and to the bushing for a temperature change. Also, the improved system can have a second bushing controller connected across two sections of the bushing to regulate relative current flow in the two sections in order to control the amount of fiber produced by each section and the program computer means additionally has a means for determining the difference in throughputs between collections of strand produced from each section of the bushing at the same time and placing these difference values in the database, and a means for averaging the difference values, and a means for comparing the difference values to determine if they are other than the value of zero, and a means for adjusting the segment bushing controller to achieve average difference value in throughput other than zero. Also, both aspects of the control system can I have a means for redetermining throughput values previously determined prior to an adjustment to incorporate a factor for the adjustment. Also, both aspects can have a means for determining an upset condition along with a means for ignoring previously determined throughput values and starting the determination of throughput values anew.

Abstract: A method of improving device performance of optical devices formed in optical substrates is disclosed. The method requires that the optical substrate material be pre-annealed to form a surface layer with a known congruent composition before diffusing the waveguide material into the substrate. By pre-­annealing all material, the diffusion rate of the waveguide material will remain relatively constant, regardless of the particular boule. The pre-annealing can be accomplished either by pre-equilibrating the lithium niobate in a vapor-phase equilibration crucible containing pre-reacted lithium niobate cullet with the desired composition, or pre-equilibrating the lithium niobate to the  Li ₂ O -rich phase boundary in a two-phase ( LiNbO ₃,  Li₃NbO ₄) powder bed.

Abstract: A method of and apparatus for processing a digital video signal to effect cut editing is disclosed. The method comprises storing a segment of an input digital video signal in a random access memory (1), the digital video signal being written in the memory (1) at a standard speed, writing proceeding cyclically from the start of the memory (1) to the finish of the memory (1), then returning to the start of the memory (1), and so on, and reading the digital video signal from the memory (1) at the standard speed, reading normally lagging behind writing by an amount substantially equal to the capacity of the memory (1), which may be several seconds. The read digital video signal is cut edited (11, 6) by step reducing the amount by which reading lags behind writing, and subsequent to a cut edit the reading speed is reduced (12, 11, 6) below the standard speed until the amount by which reading lags behind writing is restored to the normal amount. The read digital video signal is supplied to interpolation filters (9) to restore the frame frequency of the read digital video signal to the frame frequency corresponding to the standard speed.

Abstract: In a vehicle antilock brake system the brake pressure on the regulated wheel is controlled in such a way that, in order to prevent unwanted regulating processes caused in particular by axle vibrations, potholes or the like, the threshold value for the wheel rotational deceleration is briefly increased by a constant amount (SH - SG) in relation to a basic threshold value SG at the onset of a pressure fall or rise during a regulating cycle. Thereafter the threshold value is reduced as a function of the period of time taken by the pressure fall in the preceding regulating cycle. The threshold value is reduced to values ST below the basic threshold value and is maintained for a predetermined period of time (tx-ty).
