Title: Cutter bar assembly
IPC: A01D34/14
Filed: 1966-12-22
Abstract: Each of tile fixed fingers of a reciprocating mower comprises a rear section 16 attachable to the mower-bar 10, an intermediate section 17 having an upper face 23 with a central depression 24 therein and providing cutting edges 26 for co-operation with the knife-bar, and a front section 18 having a rearwardly-facing wall 39 defining the front limit of, and extending upwardly from, the upper face of the intermediate section. The central depression 24 may be a simple concavity having two terminal edges 26 or it may be, as shown in Fig. 3, a downwardly-stepped depression, in which case two additional edges 26 are provided for co-operation with the moving blades. At the lower end of the wall 39 in the front section is a slot 40 which receives the end of a spring- clip 15. The clips are U-shaped in plan having two limbs, each of which enters a slot 40 in a finger, the rear corners of the clip being secured to the bolts 13 which secure the fingers to the mower-bar 10. Held by the same bolts is a wear-plate 34 which supports the rear edge of the knifebar 33. In a modification (Figs. 8 & 9, not shown) an upstanding portion of the intermediate section has its upper face coplanar with the face 23, and the wearplate is omitted.

Patent ES-343940-A1 (ES)
Title: Method and Apparatus for Preventing Withdrawal of a Broken Yarn End from a Delivery Tube of and Open-End Spinning Machine
IPC: D01H13/16
Filed: 1967-07-28
Abstract: In a break spinning device means to detect the absence of a yarn in the delivery tube 8 is provided and linked to means to stop withdrawal of yarn when such absence occurs so that the broken yarn end remains in the tube above the position of the detection means. As shown photo-electric means 23, 24 are provided to detect yarn absence in tube 8 and a signal therefrom is fed to an amplifier 25 which in turn operates magnetic couplings Ml, M2 to stop the delivery rollers 9 and the fibre feeding rollers 4, 5. In addition a solenoid 16 is energized to displace an armature 17 and thus move a lever 14 pivoted at 13. A yarn guide bar 15 is thus lifted to remove the yarn 71 from the grooved driving roll 11 and a sector 20 is pivoted about 19 to brake the wind up spool 10 and lift it clear of the driving roll 11. The lever 14 also operates a counter 26 which thus indicates the number of yarn breaks. A capacative device or a pressure difference device may be used in place of the photo-electric device to detect yarn breaks.
Patent ES-345584-A1 (ES)
Title: Improvements in or relating to One-Piece Brake Discs
IPC: F16D69/02
Filed: 1967-09-29
Abstract: A one piece cast brake disc, particularly for disc brakes of rail vehicles, is composed of a nodular graphite cast iron consisting, by weight, of C 3À25 - 3À75% Si 2 - 2À6% Ni 0À5 -1À5% Mn 0À2 - 0À6% Cu 0À1 - 0À5% P up to 0À16% S 0À02 - 0À05% Fe (and impurities) balance. After pouring, metal in the region of the hub part of the disc is cooled at a different rate from metal in the region of the brake rings so as to produce ferrite-pearlite in the hub part thus enabling it to expand for pressing on to the wheel axle, and pearlite in the brake ring thus giving it wear resistance. The different cooling rates are produced either by disposition of heat-storing masses or exothermic masses at the hub part when the composition produces pearlite with normal cooling, or by disposition of chill irons at the brake ring when the composition produces ferrite-pearlite with normal cooling.

Abstract: A method of producing wooden boards from pieces of wood such as veneer sheets or shavings comprises first vacuum impregnating the pieces with one component of a two-component plastic adhesive prior to a bonding process, applying to the pieces an adhesive formed from an admixture of the other plastic component and then bonding the pieces together by heat and pressure. In an example beechwood veneer sheets are placed in a vacuum chamber into which is introduced a solution of 20% diammonium phosphate, 2% copper sulphate, 8% urea, and 70% water. After a certain time the sheets are removed and every second sheet coated with a film of a phenolic formaldehyde adhesive consisting of 100 parts of a pre-mix of phenolic formaldehyde, 15 parts of formalin. 10 parts of diammonium-phosphate, 25 parts of kaolin and 15 parts of paraformaldehyde. The sheets are then placed in a press and heat and pressure applied.

Title: Tire covers
IPC: B60C19/00
Filed: 1968-02-06
Abstract: A pneumatic tyre has a pseudo-camber (i.e. a characteristic of a tyre which causes the vehicle on which the tyre is mounted to he subjected to a force the effect of which is analogous to the effect caused by wheel camber) such that when mounted on an axle of a vehicle travelling at 10 km/hr. at tyre design load and pressure on level ground it gives rise to a thrust or a pull on the axle of not more than 6% of the design load of the tyre and is provided with an indication of the orientation of the tyre on the axle required to produce the thrust or pull. A tyre may be provided with a pseudo-camber by introducing asymmetry into the tyre e.g. by making the tread conical or by offsetting the crown reinforcement plies relatively to the tread. The pseudo-camber of a tyre may be measured using the apparatus shown. Two pneumatic tyres 10, 12, of which the pseudo-camber of one is known, and is preferably nil, are fitted on wheels attached to semi-axles 14, 16. Semi-axle 14 is connected to a cylinder 18 and semi-axle 16 is connected to a plunger 20, provided with a pointer 26, which is registered against a scale 28, and operable against two calibrated springs 22, 24 mounted between the plunger and cylinder.

Patent ES-429307-A1 (ES)
Title: Process for the manufacture of a plurality of filaments
IPC: D04H13/02
Filed: 1974-08-16
Abstract: A method and apparatus for making filaments and a fibrous product of randomly overlying filaments in a mat configuration bonded to each other at areas of intersection. The filaments are formed by subjecting a travelling layer of a settable, dielectric, molten polymer material to an electrostatic field of lines of flux of sufficient density and intensity to flow from the layer of molten polymer a multiplicity of filaments which are partially set as they form. The filaments are subjected to the field along enough to separate them from the surface of the layer and are then collected randomly overlying each other in a tacky condition so that they bond to each other in areas of intersection. The method may include insertion of an object in the path of the separated filaments for collecting them on a surface of the object. The object can be rotated so that a package of the matter material is formed about it to protect it. The layer can be pretreated before subjection to the field to densify discrete areas to form on the surface thereof starting points for the filaments. The apparatus for carrying out the method comprises a travelling transport for the layer in the form of a belt permeable to the electrostatic field in which case two electrodes develop the field or the transport may be conductive to act as one of the electrodes developing the field. A collector for the matter material can be constituted as a travelling electrode in the form of a conductive belt which is grounded with a potential applied across the belt transports.
