Patent ES-310380-A1 (ES)
Title: Improvements in or relating to ring spinning machine automatic doffing and donning devices
IPC: D01H9/10
Filed: 1965-03-10
Abstract: Doffing and donning apparatus for a ring- spinning machine comprises a carriage, Fig. 1, with two sets of forks each set extending radially from a shaft the first set 1 is for doffing and engage the bobbins in turn to first loosen them and then to remove them from the spindles, while the second set 3 is for donning and comprises U-members with a fork on each of the two parallel limbs, the lower forks engaging doffed spindles in turn while the corresponding upper fork takes up empty bobbins from a hopper 4 to drop them on to the empty spindles, levers actuated by the spindles being provided to impale the bobbins so donned. The doffing forks 2, Fig. 2, are arranged on a shaft which is rotated as successive forks engage the spindles as the carriage moves. Each fork is mounted by a ball joint allowing the fork a limited vertical movement. When one of the forks engages a filled bobbin, as the carriage moves it rides over an inclined surface 12 and rises to loosen the bobbin from the spindle. When the preceding fork is engaged with a spindle, as the carriage moves, it causes one arm 15, Fig. 3, of a two-armed lever to rock downwardly against the action of a spring 14. When the fork leaves its spindle, the spring is freed to raise the lever so that it strikes beneath the fork that has just loosened the bobbin and forces the 'bobbin against a plate 5 which deflects it onto an inclined surface 6 to be guided into a box 7. The donning forks. These comprise a series of U-members carrying forks 8, 8a and mounted in plates 18, 19 fixed to a shaft 22, Fig. 4. Each fork can slide in an aperture 20 in the upper plate and a guide 17 in the lower plate, the bottom fork being urged outwardly by a spring 21. The hopper 4 is replaceable and is closed by a sliding plate which is withdrawn when the hopper is in position, so that empty bobbins fall on a conveyer 27, to be transported to a vertical duct 29 in which they lie horizontally. At the inlet of the duct, one end of the bobbin is struck by a blade 31, Fig. 5, rotated by the shaft 22 of the donning-set. It thus hits against a pin 34 and is turned to the vertical and slides by gravity into a channel 30. As one of the lower forks engages an empty spindle, with movement of the carriage, the shaft 22 is rotated so that the corresponding upper fork 8 carries the foremost bobbin along a channel 36, finally displacing a spring plate 40 to release the bobbin so that it falls on to the spindle. During the movement of the carriage, one of a number of U-sectioned levers (41, Fig. 6, not shown) associated with the donning- mechanism, is acted upon by one of the spindles to displace one arm of a spring-urged bell crank, so that the other arm is stressed to deliver an impaling-blow to the donned bobbin when the first arm is released.

In a modified arrangement, Figs. 6 and 7 (not shown), the springs 11 are compressed by a screw disc (26) operated by worm gearing (23, 25) driven manually or by an electric motor (34). The slip coupling may be incorporated with a flexible coupling of the type fitted with axial resilient cylinders.

Title: Sliding Clasp Fasteners and Process and Equipment for their Manufacture.
IPC: B29C48/12
Filed: 1967-03-04
Abstract: A sliding clasp fastener comprises a pair of stringer tapes 3 on to each of which is moulded a row of interlocking elements 5 of thermoplastic material formed as continuous strips extruded on to the associated stringer tapes and having interlocking heads, in which each stringer tape is provided with upper and lower rows of the interlocking elements, 4,4 only the heads of which project beyond the edge of the tape, and the gaps between the upper and lower rows are divided by the tape, so that the heads on each tape are supported transversely in the opposing gaps by the faces of the stringer tapes. As shown, fastener elements 5 and a guide strip 11 are extruded on to the edges of open mesh stringer tapes 3 by means of a three part die 11a, 11c, 11b to produce elements along opposite edges of each tape. The die and tapes are passed through an extruder so that the die sections 11a-11c are coated on all sides with thermoplastic material and the material flows into die cavities 12 to form a strip and fastener elements on each tape. In an alternative form, split dies may be used. Specifications 1179921 and 1179923 are referred to.
Patent ES-338670-A1 (ES)
Title: Conversion of heat energy to mechanical energy
IPC: H01H37/32
Filed: 1967-03-30
Abstract: The temperature-responsive characteristic of a strip 16 of a nickel-titanium alloy is used to operate a valve 13 in a pipe 11 through which fluid such as that used in a fluid sprinkling system flows. The alloy strip which has been deformably twisted at a temperature below a critical temperature has one end secured to the valve stem 14 whilst the other end is secured to a block 17, a key 18 of which engages a keyway 21 in a boss 22 to prevent rotation of the block. On heating the alloy above its critical temperature, the valve is caused to rotate as the alloy strip returns to its undeformed state, thereby permitting the fluid to flow through the pipe.

Title: Process for washing aldehyde-regulated homo- and copolyvinyl acetates
IPC: C08F6/28
Filed: 1967-07-21
Abstract: Aldehyde-regulated mono- and copolyvinyl acetates are pre-washed with a mixture of water and acetone and/or methanol at an elevated temperature and post-washed after separating off the pre-wash liquid. By " aldehyderegulated " is meant that the molecular weight of the polymer has been regulated by the use of an aldehyde as transfer agent. Preferably the elevated temperature is from 70 to 95 C. and the temperature of the post-washing water is from 60 to 95 C. Suitable polymers are homopolyvinyl acetate and copolymers of vinyl acetate and a maleate ester, a vinyl ester of a C 8 -C 18 fatty acid or an olefin, e.g. ethylene. The polymers may be used as chewing gums.

Patent ES-347013-A1 (ES)
Title: Improvements in or relating to waveguide filters
IPC: H01P1/219
Filed: 1967-11-10
Abstract: A waveguide bandpass filter comprises main resonant cavities coupled by sections which are evanescent (i.e. are dimensioned below cut-off) at the passband frequency of the filter. In the form shown, the cavities C, E, G are tuned by coarse and fine tuning screws 3, 4 and the bandwidth is adjusted by means of screws 5 which affect the cut-off frequency of coupling sections D, F, H. As an alternative to screws 5, the blocks 9 forming the coupling sections may be provided with transversely slidable sections (7, Fig. 10, not shown). The filter is terminated by inductive irises 6. The Specification contains a theoretical discussion of the behaviour of the filter and detailed information on design procedure. It is pointed out that the filter propagates freely at frequencies above the cutoff frequency of the coupling sections and that it is necessary to provide means for absorbing or reflecting parasitic signals at these frequencies. Thus, the coupling section 11, Fig. 15(b) is associated with a narrow-band rejection filter comprising three resonant stubs 13 tuned by pistons 14. This may be converted to an absorptive constant-resistance filter (Fig. 16, not shown) which uses a resonant stub and a stub containing a matched dissipative load. Another form of narrow-band absorptive filter comprises a resonant-slot hybrid junction 19, Fig. 18, coupling the evanescent section 18 to a circular waveguide 20 containing a load 21. In a modification of this arrangement, the coupling section contains a section bounded by irises resonant at the rejection frequency, this cavity being coupled by a hole coupler to an external resonant cavity containing a dissipative load. The coupling section may, in addition, be provided with a series rejection filter comprising a central transverse post 30, Fig. 23(b). This behaves as a reflector and is situated at a point beyond the absorptive filter. In another arrangement (Fig. 25, not shown), the coupling section contains a cavity resonant at the rejection frequency provided with a tuning screw and a dissipative iron-dust slug. A series rejection filter (see Fig. 23) is situated just beyond the resonant cavity. Instead of using resonant rejection filters, the evanescent coupling sections may be constructed to have the properties of low-pass filters. Thus, the coupling sections 38(a), 38(b), Fig. 31(b), incorporate corrugated low-pass filters having a cut-off frequency below the parasitic frequencies. An intermediate coupling section is provided with a dissipative stub 40.
