Title: Process for the catalytic desulfurization of hydrocarbon oils
IPC: C10G45/26
Filed: 1961-03-07
Abstract: Sulphur-containing hydrocarbon oils are desulphurized by contact with a hydrogenating/dehydrogenating catalyst containing one or more alkali metal compounds at temperatures from 250 DEG -450 DEG C. in the presence of steam. Additionally the catalyst may contain one or more metals from Groups V-VIII, e.g. chromium, tungsten, molybdenum, manganese, iron, cobalt and nickel either in combination with each other, e.g. cobalt thiomolybdate, or with oxygen or sulphur. Specified alkali metal compounds are lithium, sodium and potassium carbonate, hydroxide, formate and acetate. The catalyst may have for supports either alumina or silica-alumina. The catalyst may be used in fixed, fluidized or suspended condition and contact between hydrocarbon oils and catalyst may be maintained continuously. The catalyst may be used as particles of 30 mesh or smaller and contact between the oils and the catalyst may be effected at atmospheric pressure up to 75 atmospheres absolute or higher. The catalyst may be sulphided in known manner, e.g. by passing thereover a mixture of hydrogen and hydrogen sulphide, carbon disulphide or butylmercaptan. Catalyst preparation may be effected by fine milling a cobalt-molybdenum-alumina catalyst and mixing the resulting powder with anhydrous soda. Thereafter a lubricant such as stearic acid or graphite may be added and the whole compressed into pellets, calcined and sulphided. Examples describe comparatively the catalytic desulphurization of xylene and kerosine. Other coal tar fractions, gasolines, gas oils and residual oils may be similarly desulphurized according to the invention. Specification 657,521 is referred to.

Patent ES-363641-A1 (ES)
Title: Time switch
IPC: G04C23/24
Filed: 1969-02-07
Abstract: An insulating frame 13 comprises a front portion 29 supporting a time switch mechanism in an insulating housing (11, Figs. 1, 2, 3, not shown) and a rear portion (30, Fig. 6, not shown) which supports a synchronous motor (26) geared to a pinion 49 meshing with a cupshaped gear 47 having a boss 46 coupled to a shaft 56 by a helical spring friction clutch 55. This allows manual setting by a knob (34, Figs. 1, 2, 3, 6 and 10, not shown) which is integral with a twenty-four hour time dial (32) secured to the front end of shaft 56, but removed in Fig. 11 for clarity. Angularly adjustable "on" and "off " arms (35, 36) mounted on the time dial (32) for clockwise rotation carry respective lugs 85 and 86 which at preset times respectively engage the ends of forwardly-extending arms 87, 88 of quadrantal bell-crank levers 89, 90, loaded by springs 105, 106 to cause stepping of a rotary contact actuator 114. When lug 85 engages arm 87 spring 105 is stressed and the end 139 of the other arm of bell-crank 89 rides up and passes over the sloping face 137 of a sawtooth projection 135 on a disc-like portion 134 of actuator 114. When lug 85 leaves the arm 87 the bellcrank 89 snaps back, due to spring 105, and the end 139 engages the steep face of tooth 135 to turn the actuator 114 nearly 90 degrees. Completion of the 90 degree step, and location of actuator 114, is provided by a spring-urged dog (147, Figs. 13 and 16, not shown), which co-operates with a four-lobed portion 145 of actuator 114. A two-lobe cam 25 near the upper part of actuator 114 is thus turned to allow a contact on spring blade 24 to engage a fixed contact carried by terminal connector 119, and a sawtooth diametrically opposite to the tooth 136 on the upper side of disc 134 is simultaneously brought into position to be subsequently engaged by the end 140 of bell-crank 90 when " off " lug 86 acts on arm 88 whereupon the actuator 114 is snapped another 90 degrees rotation and cam 25 moves blade 24 to open the contacts (as in Fig. 12, not shown). An edgewheel 37 is coupled to actuator 114 by gears 158, 157 for manual operation of the contacts and carries ON and OFF indicia (Figs. 4 and 14, not shown). The shaft 56 may be manually moved axially by its knob (34) between two positions, located by a wire spring (63, Figs. 6 and 10, not shown) entering one of two circumferential grooves (61, 62), and when in the forward position renders the lugs 85, 86 ineffective.

Abstract: An electrical switch comprises a hollow casing 11 including a base 12, fixed contacts 14 on base 12, a movable contact 17 mounted for sliding movements relative to base 12, detent means acting between casing 11 and movable contact 17 for locating it relative to base 12 in the operating positions of the switch, an operating member 27 pivotally engaged with casing 11, means on operating member 27 for releasing the detent means during movement of the operating member, and resilient means 34, 35 acting between operating member 27 and movable contact 17, the resilient means being stressed during movement of operating member 27 and serving to move movable contact 17 when the detent means is released. The detent means comprises a roller 23 resting at its centre in a slot 22 in slider 16 which carries movable contact 17, passing through windows 29 in two arms 28 of operating member 27 and resting at its ends in depressions 21a, 21b, 21c, Fig. 5 (not shown) in the side walls of casing 11. It is stated that in the position shown movable contact 17 bridges some fixed contacts 14 which are not shown. If operating member 27 is pivoted clockwise cam surfaces 31 on the inside edges of windows 29 move roller 23 upwards until it is clear of the depressions when resilient fingers 35 on member 27 force slider 11 to the left until spring 33 urges roller 23 into the next depression. When member 27 is moved anticlockwise, slider 11 moves to the right. Casing 11, slider 16 and member 27 are of moulded synthetic resin.
Patent ES-367225-A1 (ES)
Title: Vehicle drum brakes and adjusting means therefor
IPC: F16D65/56
Filed: 1968-05-14
Abstract: An internal shoe drum brake comprises auxiliary mechanical actuating means including an actuating lever 21, 23 engaging one shoe 4T at 26 and a strut 28, 29, 31 for transmitting auxiliary actuating forces to the other shoe 4L, the strut including relatively rotatable screwthreaded parts 29, 31 so that the strut is adjustable in length to compensate for wear of the brake -shoe linings, a pivoted lever 30, 37 for effecting relative rotation of the strut parts in response-to excessive travel of the brake shoes upon brake application by the auxiliary actuating means, and a pre-stressed coil torsion spring 33 coupled to the lever 30 in such a manner as to urge the pivoted lever to effect wear-compensating adjustment as required in response to operation of the auxiliary actuating means, the spring 33 being designed to yield to avoid over-adjustment under high braking loads. As shown, the actuating lever 21 is secured to a shaft 22, the pre-stressed torsion spring 33 is mounted about the shaft, and the pivoted lever 30 is rotatable relative to the shaft. One end of the spring 33 is hooked around a dowel pin 34 projecting from shaft 22 as seen in Fig. 3, while the other end 40 of the spring passes through a slot 36 in one arm 37 of the lever and engages a shoulder 38 on actuating lever 21 as seen in Fig. 2. On operation of the auxiliary actuating mechanism by the handbrake the actuating lever 21, 23, is rotated counter-clockwise as seen in Fig. 2, and the shaft 22 and spring 33 rotate with it. Lever 30, 37 is also rotated by engagement of spring end 40 in slot 36. Arm 30 of the lever is in the form of a pawl with a tooth 42 engageable with ratchet teeth on the periphery of nut 29 (see Fig. 3), so that if wear of the shoe friction 'linings has occurred the travel of pawl 30 is sufficient to rotate nut 29 in the sense to increase the length of the strut 28, 29, 31. At high braking loads, sufficient to cause deflection of the fixed structure of the brake or expansion of the drum, the frictional resistance to rotation of the nut 29 developed by the braking reaction in the strut causes the spring 33 to yield under continued rotation of shaft 22. The lower end of shaft 22 is pivotally mounted on the fixed brake structure (by a spring 32, see especially Fig. 3), and the upper end has a roller 24 engaging-the back plate 1 to facilitate rocking of shaft 22 in a plane parallel to the plate, the shaft thereby acting as a lever for transmitting brake actuating forces from the actuating lever 21, 23 to the strut. As shown in Fig. 3 the spring 33 also acts as a coil compression spring, holding the lever 30, 37 against the adjacent lower surface of lever 21 and thus biasing the pawl tooth 42 against the nut 29. On service brake application by slave cylinder 2, there are no forces tending to rotate lever 21, and hence no wear-compensating adjustment.
