Patent ES-314852-A1 (ES)
Title: Crinkle yarn machine
IPC: D02G1/00
Filed: 1965-07-01
Abstract: In a crinkling operation, thermoplastic fibre yarn Y, Fig. 1, supplied from a creel 1 passes through a tensioner 2 and a guide 3 to a feed roller 4, thence to another guide 5, over an oiling roller 6 and around a crimping head C which the yarn enters and leaves through guides 7 and 8. The head C, Fig. 2, comprises a circular row of sinker blocks 14 and sinker elements 15 each pivotable between open and closed positions in which its free end is disengaged from, or occupies, a corresponding space between blocks 14. Cams 17 and 19, Fig. 2, engage the elements so that, as the head rotates, each in turn is open at a first angular position of the head to permit the yarn to be introduced between the elements and the blocks and is then closed to entrap the yarn, and subsequently opened to release the yarn at a second angular position of the head. The yarn is set in the deformed or crinkled configuration by heating from a temperature controlled electric element 33. The cam 19, Fig. 9, is mounted on an arm 23, adjustably supported in slides in the head, by means of a rod 27 received in a bore in a mounting 29. Whenever the space between the open elements 15 and the blocks 14 is occupied by too much yarn, the cam rocks, against the action of a spring 21, and, if an adjustable amount of free travel (as determined by a set screw 31) is exceeded, this causes an electric contact 30 to close a circuit (not shown) to disengage the driving clutch of the machine.

Title: Improvements in or relating to Electrical Conduits Containing One or More Electrical Conductors.
IPC: H01R25/16
Filed: 1967-03-06
Abstract: An electrical conduit 1, of insulating material, having walls 14, 15, 16, 17 and 18 defining channels to accommodate electrical conductors 43, 24 &c., has apertures 21, Fig. 5, in its covers to admit plug pins which engage socket contacts 22, each secured to a conductor and held in position in its channel by lateral projections such as 28. The contacts 22 are made of two resilient metal strips 25 in engagement with one another to form the sockets 23, each contact being clamped into position on a conductor by means of a threaded bolt 30 passing through projection 28 and an associated nut which is prevented from rotating by a further projection. Contacts may alternatively be made from a single metal strip bent double. The position of the contacts along the length of the conduit can be determined by projections on the cover, which embrace them when the cover is in position. An earth contact comprises a member 34 having two contact strips 36 and being clamped to conductor 43 by bolt 40. The covers 2 of the conduit are detachably secured by means of snap connections near the longitudinal edges, such as a ridge 5 engaging a groove 6, the transverse edges of covers 2 being bridged by socket covers such as 3, which are fixed in position by screws 9. In an alternative arrangement one edge of the cover is integral with the conduit to form an elastic pivot, the other edge having a form of snap connection. A plurality of covers side by side may be used to cover the conduit.

Title: Waveguide filter
IPC: C08C19/28
Filed: 1967-06-10
Abstract: A band-pass filter for H-mode waveguides comprises a length of waveguide, Àe.g. rectangular waveguide, which is dimensioned below cut-off such that it supports only evanescent waves and means for terminating the length in a capacitative reactance which at a chosen centre frequency is the conjugate of the positive imaginary characteristic impedance of the length of waveguide. The specification explains the theory of such filters and shows that the band-pass limits are given by where the symbols have their usual meanings. The centre frequency is given by f 0 = #f 1 f 2 . Fig. 1 shows a three-section filter in which the capacitances are provided by screws 4. In a modification of this construction (Fig. 6, not shown), the capacitances, are provided by transverse ridges. In a modified method of realization (Fig. 7, not shown), the capacitance is provided by an appropriate length (11) of short-circuited standard (propagating) waveguide joined to the end of the length (10) of cut-off waveguide. The filter section thus formed is coupled to a standard dominant mode waveguide as a shunt or series stub (Figs. 9, 10, not shown).

IPC: C22B25/06
Filed: 1968-12-11
Abstract: Tin is recovered as volatile stannous oxide, stannous sulphide, or a tin/stannic oxide mixture, from slag by heating the slag at a temperature from 1100 to 1600 C. at a pressure not greater than 20 mms. Hg. The slag is heated in a refractory lined pot in an evacuating chamber which is gradually evacuated so that the products volatilize. Two more methods are specified. One involves streaming the hot slag into the chamber so that it falls in droplets. The second involves discharging the slag from the chamber by means of a barometric leg operated continuously or intermittently, the flow of slag being controlled by a stopper rod and nozzle assembly. Their rate of removal is encouraged by incorporating in the slag, an alkaline earth metal oxide, calcium oxide being specified. The volatilized products condense on the walls of the chamber, the pipes leading from the chamber to the evacuating pumps, and in the pump system itself, and are recovered therefrom.
