Abstract: The invention provides a means of controlling the speed of operation of a material processing apparatus, such as a ring spinning machine in a textile mill. The purpose of the invention is to allow high speed processing, whilst maintaining a high quality product. In the case of ring spinning for instance, the object is to reduce the incidence of yarn breakages. 
     The method in accordance with the invention includes controlling the speed of operation during a total time for processing a finite quantity of the material, and including the use of an automatic control apparatus preset to change the speed of the driving motor in a series of very small increments throughout a speed change time which is a predetermined percentage of the total time, between two speeds, one of which is a predetermined optimum operating speed and the other of which is a predetermined percentage of the operating speed. The essence of the invention is the selection of percentages of the operating speed and the total processing time for controlling the point from which the speed change is effected up to the operating speed or down to which the speed change is effected from the operating speed.

Abstract: A circuit for generating 2 n  test patterns is disclosed. The system utilizes a linear feedback shift register (LFSR 60) to generate a sequence of 2 n -1 test patterns. In addition, the system includes apparatus (52, 56) external to the shift register which generates a 2 n th test pattern. A switching circuit (48, 50) is employed to insert the 2 n th test pattern into the sequence of test patterns. Therefore, a 2 n  test pattern sequence is generated. The test pattern sequence produced is pseudo-random in nature. The circuit further includes an output (D0) for providing a test pattern; such output could be used for the testing of a VLSI sub-system such as ROM.

Abstract: A rotary-head assembly for the storage and retrieval of digital data on and from a series of slanting record tracks on magnetic tape in cassette form or the like, with the capability of substantially concurrently monitoring the recording being written on the tape. The rotary-head assembly includes a rotary drum to which there are mounted first and second magnetic read/write heads and first and second magnetic monitor heads. The two read/write heads alternately and overwritingly scan the magnetic tape for creating a series of slanting record tracks thereon. For monitoring the data being written by the first and second read/write heads, the first and second monitor heads scan the overwritten tracks spaced at least two tracks from the tracks being written by the first and second read/write heads, respectively. therefore, being repre­sentative of the recording on the overwritten tracks, instead of on the tracks before they are overwritten, the output signals of the monitor heads lend themselves to a more accurate evaluation of the data to be reproduced.

Abstract: A spreader bar apparatus (10A) is disclosed for separating slit portions (30-34) of a web (WA). The apparatus includes a first spreader bar (12A) which extends in a cross-machine direction (CD) relative to the web. The first spreader bar (12A) is bowed relative to the slit portions (30-34) such that the slit portions are separated axially relative to each other when the slit portions (30-34) are guided around the first spreader bar (12A). A second spreader bar (14A) is disposed downstream relative to the first bar (12A) and extends in a cross-machine direction (CD) relative to the web (WA) for guiding the separated slit portions (40-44). The second bar (14A) is bowed relative to the separated slit portions (40-44) such that each of the slit portions (50-54) disposed downstream relative to the second bar (14A) is disposed parallel to each other. A first and a second porous layer are connected to the first and second bars (12A, 14A) respectively such that when the bars are connected to a source of pressurized air, air flows through the bars (12A, 14A) and the porous layers towards the slit portions(30-34, 40-44) for generating respectively a first and second air cushion. The cushions reduce the frictional resistance between the moving slit portions (30-34, 40-44) and the bars (12A, 14A). Additionally, the air cushions reduce the noise level caused by movement of the slit portions when the slit portions move relative to and are guided by the spreader bars (12A, 14A).

Abstract: A low-level liquid scintillation measurement system for counting sample optical events resulting from the radioactive decay of a constituent of a sample to be measured while reducing the counting of background optical events which are optical events produced by background radiation and which create electrical pulses other than pulses representing a sample optical event. This system includes detection means located adjacent the sample for detecting optical events and for converting optical events into electrical pulses, coincidence sensing means for receiving the electrical pulses from the detection means and producing a trigger pulse when the electrical pulses from the detection means coincide with each other, burst detection means for receiving the trigger pulses from the coincidence sensing means and the electrical pulses from the detection means for determining the number of electrical pulses present in a selected interval following each of the trigger pulses, evaluation means connected to the burst detection means for determining, in response to the number of pulses detected in the selected interval, the extent to which the optical event represented by the corresponding trigger pulse should be treated as a sample optical event or a background event, and an active guard shield arrangement comprising an auxiliary scintillator optically coupled to the detection means. The shield is adapted to be excited by background radiation and to effectively increase the number of electrical pulses present   in the selected interval following a trigger pulse generated as a result of the coincident pulses produced due to the background radiation. The auxiliary scintillator is a glass comprising oxides of lithium, magnesium, silicon and cerium.

Abstract: This invention relates to a Viterbi decoder for decoding a convolution coded reception signal. The Viterbi decoding is an algorithm for efficiently executing the maximum likelihood decoding using a convolution code by selecting a path locating at the minimum distance from a reception series between two paths which are joined. Since it is necessary to store a state metric of each state, after the state metric of the surviving path was calculated by ACS calculation (3), it is considered to normalize metrics. However, this results in a large circuit scale and a low processing speed. Therefore, in this invention, a maximum likelihood value (11) of a present state metric is detected from a maximum likelihood branch metric pair (10) before the ACS calculation (3) and the preceding maximum likelihood state metric pair (12) and metrics are normalized (5) by using the maximum likelihood value.

Abstract: Relatively fragile components (20) for cigarette-like smoking articles are wrapped with an overwrap (42) by bringing an exposed axial surface portion of the component into resilient contact (N) with the overwrap, and by then rolling the component about its longitudinal axis (186,188) again by resiliently contacting the component. Smoking articles including the foregoing components as the distal component and at least one proximal component are made by, first, supplying a pair of distal components with their distal ends facing one another and pushed up against an interposed stop. The overwrap is slit parallel to the stop just prior to application to the distal components. After overwrapping, the distal components are reoriented so that their distal ends face away from one another. A pair of proximal components is then placed between the distal components, and each proximal component is joined to the adjacent distal component by a tipping overwrap.
