A fibrillated plastics film laminate comprises three or more layers of plastics film bonded together and fibrillated, at least two of such layers being molecularly oriented and composed of plastics material having different properties, the direction of orientation of the molecularly oriented layers being the same. The fibrillated laminated film may be made by bonding together three or more layers of plastics film at least two of said layers having different properties, and at least two of said layers being molecularly oriented, to form a fibrillatable laminate in which the direction of orientation of the oriented layers is the same, and fibrillating the laminate. At least two layers of the laminate may differ in their heat shrinkage characteristics and the fibrillation step may be followed by a heating step to induce crimping. At least two films of the laminate may be molecularly oriented to a different degree before lamination. The laminate may be fibrillated by stretching the laminate in the direction of orientation of the two films to achieve a high degree of uniaxial orientation. The laminate composed of three layers may comprise a layer of polyethylene, polypropylene or polyvinyl acetate. The laminate may comprise a layer of polypropylene bonded between two layers of polyvinyl acetate. The laminates or the individual fibres comprising the laminates may be oriented by cold drawing or by drawing at an elevated temperature below the melting point of the lowestmelting polymer. The draw ratio is usually in the range of 4:1 to 16:1 but higher draw ratios may be used.

Filed: 1973-12-20
Abstract: 1464870 Automatic control of knitting machines WILDT MELLOR BROMLEY Ltd 29 Nov 1974 [20 Dec 1973] 59261/73 Heading G3N A pattern control arrangement for a circular knitting machine produces operating pulse signals in response to either the positive going or negative going edge of triggering pulses produced by the machine and includes an inverter for the triggering pulses so that below a predetermined speed operating pulses are produced in response to completion of the triggering pulses and above the predetermined speed the operating pulses are produced in response to the initiation of the trigger pulses. As shown triggering pulses are produced by signal generator 2 responsive to the speed of the knitting machine and these pass through three level gates OR1-4, where they are inverted, to control circuitry 13 which responds to a positive going signal 14 at the trailing edge of each pulse to cause pattern  information to be read out of store 32 for computer 16 and an operating pulse sent via line 19 to the appropriate actuator on machine 4. At a predetermined speed the auxiliary circuit including OR gate DR5, integrator 26 and Schmitt trigger 27 responds to provide a signal on line 29 which causes the gates OR 1-4 to stop acting as inverters so that control circuitry 13 now responds to the leading positive going edge 30 of each triggering pulse, thus advancing the time of the actuator signal. It is stated that 20 rpm forms a suitable predetermined speed and that the auxiliary circuit exhibits some hysteresis to prevent oscillation about this speed.

Title: Method and apparatus for producing compressed digital represent ations of a visible image
IPC: H04N1/417
Filed: 1970-12-23
Abstract: 1307777 Facsimile reproduction EG & G Inc 23 Dec 1970 [26 Jan 1970] 61173/70 Heading H4F Signal redundancy in the transmission of a compressed digital representation of a graphic image 6 scanned along a pattern of mutually spaced lines, e.g. by means of a rotating drum 8 and drive screw-mounted scanner 4, is minimized by generating a digital scan signal for each line, the scan signal having a transition corresponding to each image density transition along the line, successively storing for simultaneous access the scan signals for contiguous lines, comparing corresponding portions of the two stored scan signals during the scanning of a third contiguous line and the storing of the corresponding scan signal, and producing a digital output signal representative of the second line scanned and varying in accordance with differences detected between the first and second scan signals. The output signal may be applied directly to a tape recorder 3 for facsimile storage or via a communication channel 14 such as radio or a telephone line to a receiver 16 where the coded signal corresponding to each line is interpreted by reference to the information about preceding lines previously received in order to reconstruct the image line and hence the entire image. In the embodiment signals obtained by scanning contiguous lines are fed successively through 1800-bit memories 32, 34, 36, and the comparison between contiguous lines is made in a comparison circuit 38 supplied by the last two memories 34, 36. The scanning rate of the line whose signal is being fed into the input memory 32 is controlled via program controls 44 in accordance with the number of bits of information in the preceding lines. The comparison circuit 38 generates different types of function dependent upon the relative positions of image-density transitions in contiguous lines, or the presence or absence of such transitions in either line. For the purposes of encoding each line is effectively divided into segments, each segment ending when one of these functions is uniquely defined. The output signal then consists of a series of code words, each word corresponding to one of the functions. The most economic use is made of the system by allotting the shortest code words to the functions which most commonly reoccur in the type of image being reproduced.

Title: Method and apparatus for pressing out branch pipes on thick-walled shells
IPC: B21C37/29
Filed: 1978-07-19
Abstract: The pressing out of a branch pipe (3) on a thick-walled shell (1) can be carried out by flanging the shell wall (1) around a hole formed in the wall (1). However, unacceptable distortion of the shell may result. To avoid such distortion, the inner surface of the shell wall is sized by an arbor (7) during the final stage of the flanging operation in the zone around the hole. Simultaneously, a force (P3) is also applied to the outside of the shell in the region opposite the hole considered axially of the branch pipe (3) being formed. The described pressing method can be used on very large thick-walled shells such as casing shells of atomic reactors. <IMAGE>
