Title: Method for the pressure-tight connection of a tube to a plug inserted into the tube, and a pressure-tight connection produced by this means
IPC: B23P15/00
Filed: 1981-02-03
Abstract: In the method for the pressure-tight connection of a tube to a plug inserted into the tube, the end of the tube is forced into a preferably triangular annular groove in the plug. A radially projecting collar is formed on the plug next to the annular groove and the end of the tube is then pushed over the annular groove onto the plug until it rests against the collar. Finally, the collar together with the end of the tube is forced into the annular groove. The pressure-tight connection obtained is distinguished by the fact that the collar is produced as an integral part of the plug, the end of the tube being firmly enveloped both on the outside and on the inside and the resulting connection being sealed at two points.

Patent ES-8302275-A1 (ES)
Title: Refrigeration system for a chilled product vending machine.
IPC: F25D11/00
Filed: 1981-09-11
Abstract: A control circuit for cycling the evaporator fans on and off independently of the operation of the compressor of the refrigeration system is described. The evaporator fan is cycled on with the compressor and continues to run during the entire compressor ON cycle. A first timer causes the evaporator fan to run for an additional delay period following the cycling OFF of the compressor and the fans continue to blow air over the evaporator coil until the temperature of the evaporator coil is sufficiently above the freezing point of water (32 DEG F, 0 DEG C). The fans are then cycled off. A second cycling timer is provided to intermittently cycle the evaporator fans on and off for predetermined short intervals following the above-described delay period, and during the time when the compressor is off. A third timer is provided to preclude freezing of the vended products and/or the evaporator coil when a vending machine is disposed in a below freezing environment. This timer is enabled when the thermostatic temperature switch which controls the compressor opens, and will time out to cycle on the evaporator fans for continuous operation for a predetermined period of time if the temperature switch remains open in excess of a predetermined period of time.

Patent ES-8403754-A1 (ES)
Title: Improvements in or relating to the forming of extrusion dies.
IPC: B29C48/30
Filed: 1983-05-24
Abstract: A method of forming an extrusion die comprises forming an extrusion aperture in a die piece, forcing a flowable material partly through the extrusion aperture so that the leading surface of the material becomes deformed in the extrusion direction, and then removing the exposed surface of the extrusion aperture, by chemical or electro-etching, so that the effective axial bearing depth of the extrusion aperture at any location around its periphery corresponds to the deformation of the leading surface of the flowable material at that location. The axial bearing depth of the completed die at any location is thus inversely proportional to the resistance to flow at that location, resulting in substantially uniform flow over the whole of the die aperture.
Patent ES-8404033-A1 (ES)
Title: Continuously variable combined transmission.
IPC: F16H37/02
Filed: 1983-07-07
Abstract: Continuously variable combined transmission with a hydrodynamic unit (1) at least in three parts, provided with an adjoined bridge coupling (11) and with a continuously variable mechanical transmission (2), wherein the continuously variable of the rotation torque is achieved by means of the continuously variable mechanical transmission (2) and wherein the inversion for the reverse and forward running, as well as this starting in these two operation modes are carried out by the hydrodynamic unit (1). The stator (14) of the hydrodynamic unit is secured to the input shaft of the continuously variable mechanical transmission by means of a coupling (4) or a unidirectional coupling (15). In the forward running operation, as well as in the short starting phase, the hydrodynamic unit (1) effects the bridging. This switching is achieved as a function of the rotation speed and may further be influenced as a function of the rotation torque. In both operation modes, the continuously variable mechanical drive (2) is in a position for transferring the maximum rotation torque. The brakes (3) and the clutch-couplings (4) may also be designed as claw couplings with synchronisation device.

Title: Information display system.
IPC: G06F3/037
Filed: 1983-08-09
Abstract: An information display system which can produce an information display (e.g. on a television monitor) from any one of a plurality of different information sources. The information sources are associated with different facilities such as teletext and viewdata. In order to obtain information from a particular information source, the associated facility option is selected from the available facility options by selecting from the television screen "nested" areas which pertain to one or more facility options. The selection can be effected using a touch-sensitive screen which overlies the television screen. The selection process may comprise the display of a number of successive display frames containing "nested" areas. The selection of an area in one frame produces a fresh display frame which redefines areas which are nested within the selected area.

Title: Percussion fuze for spinning missiles
IPC: F42C15/24
Filed: 1984-09-24
Abstract: A detonator capsule (16) is mounted in a rotor (12), locked in the safe position by a bolt (21) which is pressed downwards by a firing pin (2) and a spring (7). The spring force is transmitted through a spiral band (18) and a coiled wire (22). - When the projectile is spinning during slight, balls (4) in radial holes (3) in the firing pin move radially outwards under centrifugal force against the conical surface (5) of a bush (6) causing the pin to move axially against the spring. This removes the load from the spiral band which then expands radially and allows the coiled wire to move axially and radially and allow the bolt to move upwards so that the rotor brings the capsule to the firing position.

Patent ES-8700561-A1 (ES)
Title: Method and apparatus for attaching fly strips to a slide fastener chain.
IPC: A41H37/06
Filed: 1985-09-13
Abstract: An automated assembly produces a continuous, contiguous series of individual pieces sewn in a continuously operating sewing machine by conducting successive pieces to the sewing station through a feed station. The feed station may receive the pieces intermittently and irregularly but is equipped with guides and drives for accelerating each successive piece relative to the preceding pieces being sewn in the sewing machine to overtake any spatial gap between the trail end of the preceding piece and the lead end of the succeeding piece so that these ends abut prior to completion of the sewing of the preceding piece. The drives are continuously operating, yet overlapping of the end-to-end relation of the pieces and bunching or furling of the pieces due to this end-to-end abutment are prevented by guide surface confinement of the pieces in the feed station and a predetermined capability for slippage in the drive. The assembly has application in the making of closures for fly openings.
