Patent ES-275372-A1 (ES)
Title: Method of coloring glass and said colored glass
IPC: C03C21/00
Filed: 1962-03-10
Abstract: To colour a sheet of glass obtained by flowing on a bath of molten tin or tin alloy, that surface with which the glass has been in contact is coated with a reducible salt of a monovalent metal and the coated glass heated to a temperature of 600 DEG to 700 DEG C. Preferably an aqueous solution of the salt is used and the water evaporated before the heat treatment which lasts for several minutes. The solution may be sprayed on to the surface of the glass either when it is cold or already at the required temperature. After cooling the sheet may be washed. The colour extends into the surface to give a definite thickness of colour and the intensity of colour may be varied either by varying the concentration of the solution or by repeated applications. The salts used are copper sulphate, 2 to 10% by weight for cold application, 10 to 20% to hot glass to give colours ranging from pink to ruby red and silver nitrate, 0.05 to 0.15% by weight for cold application, 2 to 3% to hot glass to give colours ranging from pale yellow to brownish yellow.

Title: Improvements in or relating to electromechanical vibratory devices
IPC: H04R11/00
Filed: 1965-02-27
Abstract: In an electromechanical vibratory device, a driving member and a driven member are connected by a resilient intermediate member which is in frictional contact with either the driven or driving member, the value of limiting friction being such that the intermediate member will slip under a force which would otherwise displace either or both of the driving member and driven member from their equilibrium position by more than a predetermined amount. A telephone receiver (Fig. 1) includes a rocking armature 13 provided with a lug 16 which is gripped by a U-shaped wire spring 19 which passes through apertures 18 in a diaphragm 17 and is secured thereto by " Araldite " (Registered Trade Mark). The value of the pressure of spring 19 upon lug 16 sets an upper limit to the force which can be transmitted between the diaphragm 17 and armature 13. Only one arm of the spring 19 may be resilient. Lug 16 may be notched for location of the wire 19 (Fig. 4, not shown) and the notches may be enlarged beyond the exact size to fit the spring 19. Alternatively, the U-shaped spring 19 may bear on the inside of a slot or hole in the armature lug 16 (Fig. 5, not shown). The closed end of the U-spring may be located with the closed end of the U rigidly secured to the armature lug 16, the arms then being in frictional contact with the diaphragm 17 within the two holes 18 (Fig. 6, not shown). Alternatively the spring 19 may be J-shaped (Fig. 7, not shown). Strip may replace wire for the spring 19. Alternatively, a multi-pronged resilient member may have frictional contact at more than two points.

Title: An improved textile process for producing permanently kinked thermoplastic yarns and apparatus therefor
IPC: D02G1/14
Filed: 1967-02-21
Abstract: A yarn 1 wholly or partly of thermoplastic components is fed between interengaging parts such as blades P and a toothed belt 6, heated as it is deformed into kinked form and allowed to remain in a kinked state, e.g. on belt 6 until it has cooled and permanently set. As shown blades P are radially slidably mounted in a rotating drum 12 and are caused to project by cams to engage the recesses in belt 6 the blades P are heated in their rotation by heating means 15. The yarn approaching the kinking parts passes about a rubber 2 and then along a surface 3 down which water flows from a container 7. Upon being heated by blades P the water is converted to steam and the yarn steam treated. If the yarn is not forwarded through the machine roller 2 is moved to lift the yarn from the water on surface 3 and heater 15 is retracted. The kinked yarn from the apparatus may be fed directly to a carpet or fabric forming machine.

The wire binding elements deposited on the bar 82 are aligned on the bar by fingers on the pusher 68 and a spreader 88. Following transfer of the aligned wire element to the jaws 20 by pivotal actuation of the bar 82, the jaws are rotated along cam surfaces 31 by links 38, 40, the respective ends of which are articulated to a fulcrum lever 42 and the jaws 20.

Title: Intravenous fluids administration apparatus
IPC: A61M5/152
Filed: 1972-09-28
Abstract: Apparatus for parenteral fluid administration to a patient wherein a pliant bag containing the liquid to be administered is supported between two pressure pads having mutually-confronting, spaced-apart, pressure-applying faces. A side edge and the bottom edge of one of the pads is offset from the corresponding side and bottom edge of the other pad. As one pressure pad approaches the other, pressure is applied to the pliant bag and the liquid is forced therefrom through a bottom outlet disposed below the pressure plates. When the pliant bag is fully squeezed and its side-walls are in contact, portions of the pliant bag adjacent the offset bottom edges and the offset side edges of the pressure plates form a lateral duct at the bottom of the bag for the remaining liquid and a riser duct which is in communication with the lateral duct and extends for the full height of the bag interior. Any gases present in the pliant bag rise to the top of the riser duct while the liquid remains at the bottom of the bag in the lateral duct. Thus no gas is ever administered to the patient.
