Title: Mixing and Pelletizing Machine
IPC: B01F7/02
Filed: 1979-02-10
Abstract: A mixing and pelletizing chamber includes a semicylindrical flexible trough (22) of rubber or other material in which a rotor assembly (70) mixes and pelletizes material moved from an inlet end (90) to an outlet end (40). Springs (50) are attached to the trough to resist movement of the trough in the direction of the rotation of the rotor assembly, to cause flexing and prevent material build up.

Patent GB-2034087-A (GB)
Title: Dot matrix character printer with variable speed control
IPC: G06K15/10
Filed: 1979-10-10
Abstract: A dot matrix character printer can print characters at variable speeds and with variable pitches (widths), using transition and increment counter means (86) comprising programmable radix counters which control actuation of the printing solenoids based on print head position, with the actuation position being varied with print head velocity, to compensate for the distance travelled by the print head during the time between solenoid actuation and print wire impact; this permits operation at variable printing rates. Printing rate is limited by the cyclic rate of the print head, with an additional limitation based on dot printing density which prevents excessive heating of the printing solenoids. There may be a single column of print rods, or two columns with relative vertical displacement of half a dot spacing for better quality. <IMAGE>

Title: Method of and Device for Compensating Errors in Sliver Density Control in Textile Machines
IPC: D01H5/32
Filed: 1980-09-17
Abstract: The present invention relates to a method of compensating errors upon sliver density control in textile machines provided with a controlled drafting field, particularly drawframes, in which said errors are originated by dissimilar conduct of the sliver to be drafted upon scanning its density, due to different withdrawing speed and/or degree of draft.

Title: Screens
IPC: B07B1/46
Filed: 1981-02-13
Abstract: A screen for separating and grading according to particle size has a series of modular screen mat elements mounted thereon and secured by expandible fasteners. The elements are mounted in edge-to-edge relationship in a staggered configuration so that screening zones between adjacent screen mats overlap each other in the intended direction of flow of particulate material over the screen. The staggered relationship between the mat elements may be achieved between adjacent rows of elements by each mat being formed from a standard modular size which is divided to provide a half element in a row. Preferably the mat elements have ribs by which they sit on supporting members of the support frame and are secured by fasteners through the ribs. The support frame may be rectangular having edge members and an array of frame members extending between the edge members on which frame members the mat elements sit for support.

Title: Complex digital multiplier
IPC: G06F7/48
Filed: 1981-03-12
Abstract: To multiply complex numbers each complex quantity is stored in a memory location (1, 2 and 3, 4) of a processor in the format W1=2<N>A+B and W2=2<N>C+D: that is, the real part is in the more significant half of the memory location. The two words W1 and W2 are then applied to a multiplier to give a product:  W1W2=2<2N>AC+2<N)<AD+BC)+BD. Then the middle byte (AD+BC) is applied to an output latch (9) as the imaginary portion of the product. The third byte (BD) is subtracted from the first byte (AC) by a subtractor (7) the output of which is placed in another latch (8) as the real portion of the product. This reduces the number of processing steps, and current of equipment needed, as compared with conventional approaches. In an alternative, the positions of real and imaginary parts of one of the complex numbers are interchanged, in which case the words in the memory locations are in the format W1=2<N>B+A and W2=2<N>C-D. The product is then:  W1W2=2<2N)<BC)+2<N)<AC-BD)-(AD). In this case the difference between the first and third bytes gives the imaginary part of the product and the second byte gives the real part. <IMAGE>
