Patent ES-366653-A1 (ES)
Title: All-welded furnace construction
IPC: F22B29/06
Filed: 1969-04-30
Abstract: An all-welded furnace construction for a oncethrough vapour generator comprises a rectangular furnace enclosure including two oppositely facing walls and side walls therebetween each wall comprising a number of substantially parallel upright finned tubes welded together to define each wall including the lower parts of the walls headers connected to the tubes so that the tubes are divided into a number of flow passes connected in series the headers and their connections to the tubes being arranged so that the tubes adjacent to and on either side of the enclosure corners and defining each corner are of the same flow pass. The flow from the economizer is passed equally to two vertical headers 26, 261, Fig. 1, each feeding the tubes of one half of a vertical division wall 24 (pass A). From the division wall, the flow is taken via a downcomer to a single header 28 and thence through the central tubes 22a of the flat floor 22, these tubes being bent upward to form the central tubes 14a of the front wall 14 (pass 1). From the tubes 14a, the flow is taken to inlet headers 30, 32, 34, 36, 38, 40 and thence through pass 2, comprising the entire side walls 18, 20, the side portions 16b and 16c of the rear wall 16, and the side portions 22b and 22c of the floor 22, the side portions 22b and 22c being bent upwardly to form the side portions 14b and 14c of the front wall. Finally, the flow passes to header 42 to flow through the central portion 16a (pass 3) of the rear wall 16. Thus, the three sides of each of the four bottom corners of the furnace enclosure are formed by tubes of the same pass (pass 2), whereby temperature differences producing thermal stresses in the welded connection between these tubes are avoided. As shown in Fig. 2, the tubes of each pass are welded together through fins. Where the tubes of pass 1 of the floor 22 pass through pass 3 of the rear wall 16 to join the header 28, they are bent as shown so that each group of four tubes is aligned in a vertical plane. The resultant gap in the floor is bridged by a seal plate 50 welded to the tubes. In a modification, the flat floor is replaced by a hopper bottom. For this purpose, the tubes which would have constituted a flat floor are bent downwardly to form one side of the hopper, while the other side of the hopper is formed by a continuation of the rear wall.
Patent ES-367788-A1 (ES)
Title: Method for making coils for armatures of electrical machines or the like
IPC: H01F41/071
Filed: 1969-05-28
Abstract: Armature coils for use in electrical machines are produced on a revolving pattern of polygonal outline. A continuous length of wire having a current-conducting core surrounded by an insulating sheath is fed under tension to the peripheral surface of the revolving pattern. A set of pushers cooperate with the pattern to move successively formed convolutions axially of the pattern. A cutting device which severs the wire between selected convolutions to form a succession of coils comprises a finger which orbits about the pattern and a reciprocating device which moves the finger axially at predetermined intervals so that the finger loops the wire between selected convolutions and moves the thus engaged part of the wire against a counterknife which is adjacent to the periphery of the pattern. A removing device strips the insulation off those portions of the wire which are to be severed by the cutting device so that the coils are formed with blank terminals.
Patent ES-368124-A1 (ES)
Title: A device for focus maintaining in an optical instrument
IPC: G02B21/24
Filed: 1969-06-07
Abstract: Automatic focusing of an optical instrument is obtained by moving the objective lens rectilinearly parallel to its optical axis in accordance with the increase or decrease in the light received in a light sensitive system after passing through an element which produces substantial spherical aberration of the image. The objective lens 1 is mounted in the centre of thin annular plate 5 which forms the armature of electromagnet 6. The image from lens 1 passes through binocular 11 one part going to an eyepiece and the other part to a spherical aberration variator 12 which converts the variations in contrast due to focusing into variations in luminous flux. This flux passes through a further binocular to lenses 18, 17, to photo-resistive cell 15 and photo-emissive cell 14. The lenses 18, 17 are adjusted so that cell 15 receives the flux from the field of view in the focusing plane and cell 14 receives flux from the same field of view but outside the focusing plane. By this arrangement changes in overall illumination produce opposite effects in the detectors 14, 15 which cancel and have no effect on the energization of the electromagnet. Variation in focus will however only affect the illumination of photoresistor 15 and will cause a change in the energization of electromagnet 6 to restore the focus.

Title: Means and method of controlling the speed of a circular knitting machine
IPC: D04B15/94
Filed: 1969-11-07
Abstract: A circular knitting machine is driven at any selected one of a plurality of speeds from a source of power through a variable-speed hydraulic driver of the known pump and motor type (preferably a Carter Gear) which is automatically adjusted to give the selected running speed by control apparatus actuated from the main pattern drum of the machine. The pump is driven at contact speed from the source of power and the control apparatus acts through a relay to vary the pump output and thereby to vary the speed of the motor, the motor being connected to the needle cylinder. The control apparatus comprises a mechanism having a speed control member spring biassed to move from a stop position to vary the pump output, and a limit device adjustable from the pattern drum to provide alternative limits to movement of the control member away from the stop position. The control member is latched in the stop position by a latch which is released by a start button, and provision is made for stopping the motor at the will of an operator and upon functioning of a stop motion, and for a high speed, a low speed, and at least one intermediate speed.

Title: Apparatus for manipulating a quantity of radioactive material between a stored position and a use position.
IPC: G21F7/06
Filed: 1979-11-27
Abstract: Apparatus for manipulating a quantity of radioactive material between a stored position and a use position is provided with a coupling apparatus for separably connecting cable controls to a storage unit at the storage position, having a coupler component fixed to the storage unit and a separable component (40,42) fitted to the control cable.

The fixed component (20,22,32,34,38) locks the radioactive material leader for safe storage when the control cable is disconnected. Connection of the control cable permits the operator to release the lock on the leader. The act of releasing that lock establishes an interlock which prevents removal of the separable component (40,42) from the fixed component (20,22,32,34,38).
