Title: Improvements in apparatus for producing knotted pile fabrics
IPC: D04G3/02
Filed: 1925-10-20
Abstract: 264,579. Oldroyd, F. H. Oct. 20, 1925. Pile-fabric loonms.-In apparatus for producing knotted pile fabrics such as carpets, wherein during the weaving of the foundation the tufts are knotted thereto, each tuft piece is measured off from a continuous length of yarn &c. preparatory to its separation from the said length and insertion in the fabric by means of a number of pairs of flat tubular arms 2 secured by members 3 in slots 4 in a rotatable hub 1. The pairs of arms are arranged at equal distances apart. Each arm has a flared slot 6 at its open outer end and is also provided with a U-shaped spring 7 disposed as shown. The yarn 8 under tension is pressed between the free limb of one of the springs 7 and the rearmost side of the corresponding slot and is then wedged between the spring and the two surfaces at the rear side of the slot. The hub 2 is then rotated and the yarn is caused to engage and move down to the bottom of the next slot, and as the hub is further rotated the yarn is engaged and firmly held in the slot 6 of each succeeding arm as shown in Fig. 1. The yarn is then severed by a device acting in the gaps 5, thus leaving lengths of yarn extending in a straight stretched state between the pairs of arms ready to be removed laterally for insertion in the fabric being woven. The slots 6 are thus forced in succession and in turn again engage the continuous length of yarn, so that the arms 2 repeatedly measure off lengths of the yarn as the hub rotates. A modification is described wherein a spring-controlled U-shaped jaw on each arm co-acts with a single jaw-like part of the arm. According to the Provisional Specification, the hub is mounted on a stationary stud &c. having at its rear side a part of peripherally square form provided with a stud on each of its flat sides.

Title: Biaxially orientated nonwoven fabrics
IPC: D04H1/70
Filed: 1977-06-23
Abstract: Fibres of limited length form strip-shaped regions of higher and lower fibre density which are arranged in an alternating sequence adjacent and parallel to one another. The fibres are present in a uniform distribution in the said regions. At least some of the fibres extend beyond the limits of adjacent regions. The majority of the fibres or fibre parts (20) in the strip-shaped regions of higher fibre density are folded transversely to the strip in a zigzag-like manner (22). The segments of the folded fibres are arranged at least approximately parallel to one another and are oriented virtually in the longitudinal direction of the strips. The majority of the fibres or fibre parts in the strip-shaped regions of lower fibre density are oriented transversely to the strip. The quotient Tensile strength transversely to the strip direction DIVIDED Tensile strength in the strip direction  always has a value of less than 2. The composite textile material is produced by introducing a carded fibre fleece (31) between a stretched screen (32) and a set of strip-forming bars (33) and by directing, for example via nozzles (35), a flowable medium, preferably water, onto the strip-forming bars. <IMAGE>

Title: Improvements in variable voltage control circuits
IPC: G05F1/32
Filed: 1949-10-20
Abstract: 674,996. Rectifying. HINKSMAN, E. A. Oct. 18, 1950 [Oct. 20, 1949], No. 26925/49. Class 38 (ii). A circuit for regulating the direct current obtained from an A.C. source 9 comprises one, or more, inductors 5 arranged in series with the load 8, one or more half-wave rectifiers 6, and a variable shunt 10 in parallel with the, or each, rectifier 6. When the variable resistor 10 is at its maximum resistance point the A.C. component in the load circuit is very small whilst the D.C. component is large. Under these conditions the inductor 5 is wholly or partially saturated so that its impedance is low and consequently a large direct current will flow in the load 8. At the other extreme of the resistor 10, the D.C. component is small, thus the inductor 5 becomes unsaturated so that the D.C. in the load circuit is small. By the use of an inductor 5 large changes of D.C. in the load can be effected by small currents flowing in the variable resistance 10. A switch 11 is provided to short circuit the rectifier to prevent D.C. flowing in the load 8. In another embodiment a full-wave rectifier circuit is shown in which the A.C. circuit and the D.C. circuit are separate. Specification 579,444 is referred to.
