Patent ES-387880-A1 (ES)
Title: Method and apparatus for the production of textile fabrics and the fabric produced thereby
IPC: D04B39/06
Filed: 1971-02-02
Abstract: A textile fabric is produced by employing both weaving and knitting techniques simultaneously. The weftwise extending yarns of the fabric are formed by knitting together, within a shed, adjacent loop forming yarns present in such shed and extending in the direction of the warp yarns by needles which are caused cyclically to move into and out of the shed through the sheet of warp yarns, the loop forming yarns being shifted laterally relative to the needles for engagement with respective such needles and the needles being co-operable with different loop forming yarns on successive insertions through the sheet of warp yarns for stitch formation. The co-operation of the needles with different loop forming yarns on successive insertions is achieved by a relative transverse movement of such yarns and the needles.

Title: Portable manually controlled hydraulic pipe bending apparatus
IPC: F04B49/24
Filed: 1976-04-02
Abstract: A pipe bending device is manually operated to pump hydraulic fluid, under the influence of a first reciprocating piston, to extend a second reciprocating piston to bend the pipe. The hydraulic fluid is urged on the pressure stroke of the first piston past a first ball valve and further hydraulic fluid is drawn by the first piston past a second ball valve upon the suction stroke of the first piston. A manually operated lever operates the first piston by swinging movement of the lever through a predetermined angle. A third piston is contacted by that same lever upon further swinging movement of the handle beyond that predetermined angle, in order to open a return passageway for the hydraulic fluid to release the device. The return passageway can be controlled by a third ball valve, or by pins that open both of the first two ball valves.
