Patent ES-461816-A1 (ES)
Title: Polymer filament manufacturing device having reduced vertical size
IPC: D01D5/092
Filed: 1977-08-22
Abstract: A polymer material in liquid form is continuously extruded through the spinning nozzles of a spinning head to thereby form filaments which drop downwardly through a blowing shaft positioned beneath the spinning nozzles. The filaments are entirely cooled, solidified and recrystallized during passage of the filaments through the blowing shaft. A drawing off roller in the form of a guide roller is located at the lower end of the blowing shaft to draw the filaments laterally from the blowing shaft, over a guide roller, and substantially vertically downwardly from the guide roller to a winding machine whereat the filaments are wound up. The winding machine is preferably located laterally of the blowing shaft, with the guide roller positioned at a level which is higher than the level of the drawing off roller. Thus, the filaments move from the drawing off roller to the guide roller in an upwardly inclined direction. The filaments are subjected to any necessary moisturizing and/or treatment operations during the passage of the filaments downwardly through the blowing shaft.
Patent ES-463392-A1 (ES)
Title: Method and apparatus for filling containers with liquid
IPC: B67C3/04
Filed: 1977-10-20
Abstract: Method and apparatus are disclosed for filling open-top containers with material capable of flowing such as liquid while preventing contamination of the container exteriors by liquid overflow. The containers are advanced along a predetermined path. The liquid is discharged towards the open tops of the containers to be filled in a substantially continuous sheet, descending adjacent the predetermined path. The containers are advanced beneath the liquid sheet with the containers tilted at a predetermined angle to the vertical. The tilted containers are overfilled and the overflowing liquid leaves the tops of the containers generally at the tilted lower top portions thereof. Streams of air are directed towards the tilted containers below the open tops thereof to cause the air to pass around the peripheries of the containers adjacent the container tops. The air flow prevents the liquid from escaping the open tops of the containers except substantially at the lower tilted top portions thereof, where the air flow causes overflowing liquid to be deflected away from the sides of the containers. The exterior of each container is thereby kept free of liquid.

Title: Transmission
IPC: F16H3/62
Filed: 1977-12-20
Abstract: A planetary transmission for selectively shifting among four forward speeds includes a first ring gear secured to a drive shaft. The first ring gear drives a compound planetary gear set which is journaled on a driven-shaft-connected planet carrier. A first planet gear set of the compound planetary gear set meshes with a carrier-journaled, third planet gear set which meshes in turn with a second ring gear. The first planet gear set further meshes with a first sun gear which is concentric with the first ring gear and which encircles and is clutchable to the driven shaft to provide one forward speed ratio between drive and driven shafts. A second plane gear set of the compound planetary gear set meshes with a second sun gear which is coaxial with the first sun gear and concentric with the second ring gear. First, second, and third brakes are respectively connected to the second ring gear, the second sun gear, and the first sun gear to stop and allow rotation of said gears to provide three additional forward speeds.

Patent ES-483078-A1 (ES)
Title: Power brake unit
IPC: B60T13/12
Filed: 1979-08-02
Abstract: A power brake unit for automotive vehicles comprising a brake valve through which pressure-transmitting fluid is metered from a fluid source into a booster chamber to actuate a booster piston. A hydraulic transmission ratio provided by an input piston connected to a brake pedal and an operating piston connected to the brake valve reduces the pedal actuating travel when the fluid source is intact and is ineffective in the event of a failure of the fluid source. Only non-boosted forces are transmitted through the hydraulic transmission ratio. Should the fluid source fail, the hydraulic transmission ratio is rendered inoperative in a simple and safe manner.

Patent ES-8204128-A1 (ES)
Title: Self-regulating heater valve - has spring-biased body in housing moved downwards by liquid flowing through perforations formed in it
IPC: F23N1/08
Filed: 1981-06-25
Abstract: The self-regulating valve acts directly between the liquid and the gas flowing through a heater, having a chamber for the liquid from the main pipe. The chamber (1) is formed by two recesses (2,3) facing towards each other in components between which is a rigid body (5) joined to them along its periphery by an elastic ring (4). The liquid from the main pipe flows into the top recess, exerting pressure on the body, through which it flows via perforations (6) into the bottom one, and from there to the radiator supplied by the heater. The flow of the liquid causes downward movement of the body, whatever its pressure and flow rate.
Patent ES-8300941-A1 (ES)
Title: Single solenoid floating piston distributor pump.
IPC: F02M41/06
Filed: 1981-12-16

In order to vary the quantity of fuel stored in the metering chamber (40) during the downward movement of the floating piston (56), the control valve (18) is variably opened for the admission of fuel at supply pressure into the timing chamber (50), thereby arresting the metering piston (56) in a predetermined position.
Patent ES-8303601-A1 (ES)
Title: Photoelectric obstruction detector for elevator doorways.
IPC: B66B13/26
Filed: 1982-02-10
Abstract: In the entranceway between an elevator car and a floor are two oppositely sliding doors (10, 20). The approach of these doors is controlled by a detection system that senses the presence of objects between the doors. This system includes, on each door, a plurality of emitters (12, 22) which are vertically spaced apart the door edge (11, 21), for radiating non-collimated light towards the edge of the other door. At the top and bottom portions of each door edge there is a sensor (13, 23), which can receive the radiation for the emitters on the other door edge. The emitters on each door edge are sequentially turned on and the sensors on the opposite door edge provide a corresponding signal as they are turned on, unless an obstruction is in the way, causing the detection system to generate a signal that thus indicates that an objet is between the doors.

Title: Orthogonal dressing of grinding wheels.
IPC: B24B53/08
Filed: 1985-08-26
Abstract: In dressing a grinding wheel having a non-cylindrical contour, the wheel is moved in a path corresponding substantially to the desired wheel contour by first and second CNC controlled slides while a single point diamond or diamond roll dresser is rotated by a CNC controlled rotary mechanism through selected angles during traversal of the wheel therepast to maintain a vertical reference plane containing the centerline or mid-plane of the diamond dresser point or radius substantially orthogonal to a vertical reference plane containing a tangent to the wheel contour path. Maintenance of the orthogonal relationship between the single point diamond dresser point or radius and wheel contour path during traversal results in the desired wheel contour being accurately dressed.
