Patent ES-349664-A1 (ES)
Title: Method for producing alkylated compounds
IPC: C07C2/62
Filed: 1968-01-23
Abstract: A mixed alkylation feed 10 comprising isoparaffinic and olefinic hydrocarbons is introduced as a plurality (2 or more) of longitudinally spaced streams into elongated reaction zone 11, where they react in the presence of a liquid catalyst (particularly HF). Reaction zone 11 contains internal cooling means (not shown) supplied by cooling pipe 12 with exit 13, and the rate of passage of feed through each inlet port is adjusted so that the heat evolved in the reaction is dissipated by the cooling means prior to the reaction mixture reaching the next succeeding downstream inlet. Effluent 15 is separated in zone 16 to yield alkylate 17 and recycle catalyst 14 which, together with makeup catalyst 18 as desired, is pumped by 19 back to zone 11 without intermediate cooling. A pressure drop of at least 0À136 atmospheres is maintained across zone 11, and preferably also across separation zone 16. The process is particularly suitable for alkylating isobutane with butylenes, but isohexane as the isoparaffin, and olefins from propylene to heptene are also specifically mentioned. Alternative catalysts to HF are mixtures of sulphuric and phosphoric acids, mixtures of hydrochloric acid and certain complexes of AlCl 3 and BF 3 , or sulphuric acid alone.

Title: Hack saw machine
IPC: B23D51/18
Filed: 1968-03-21
Abstract: A hack-saw machine comprises a saw blade 2 mounted in an oblique position to the direction of movement of the saw bow 1 and its guide means during its cutting stroke, and an automatic hydraulic control mechanism for pivoting the saw bow so as to lift the blade off the workpiece at the end of the cutting stroke, for lowering it upon the workpiece at the end of the return stroke, and for producing the desired cutting pressure of the saw blade, a torque acting upon the guide means of the saw bow tending to lift the blade at all times off the workpiece and an hydraulic cylinder 12 pivotally connected to the guide means exerts a force thereon in the direction opposite to that of the torque, and the hydraulic cylinder is connected to a control chamber 17 in which a piston 18 is displaceable by a control element 19 connected to and actuated by the driving means 20 of the saw bow so as to vary the volume of the control chamber. The saw bow 1 and guide means 3 therefore are mounted on a pivot 5 on the machine frame 6, the centre of gravity of the bow and guide means acting in the direction 14 to lift the block from the workpiece 9. The hydraulic cylinder acts in the opposite direction to the arrow 14. The cylinder 12 is connected by a conduit to the control chamber 17, the piston 18 of which is movable by a cam 19 on a shaft 20 which effects the reciprocation of the saw bow 1. A second cam 21 on shaft 20 engages a follower on a lever 22 which is mounted on a pivot 23 and engages a pair of levers 24, 25 on pivots 27, 28. Lever 24 actuates a feed pump 37, 38 connected by one-way valves 50, 52 to a tank 51 and the control chamber 17 and cylinder 12. Lever 25 engages an intermediate lever 39 which in turn engages a differential valve 41 which is mounted on a slide member 44 adjustable by a rack-and-pinion 45, 46 and has a plunger 42 engaging a stationary cam 43. The pivots 27, 28 are mounted on a slide member 26 movable in the direction of the arrows 36 by an arm 29 which is mounted on a pivot 30 on the guide means 3 and is integral with a lever 31 having a follower 32 engaging a cam 33 on the frame 6. In operation, the reciprocation of piston 18 in control chamber 17 lifts and lowers the saw blade in time with reciprocation of the saw blade and controls the pressure applied by the blade 4 to the workpiece. During the return stroke, the feed pump 37, 38 is actuated by cam 21 to pump a predetermined amount of fluid into cylinder 12 so that at the start of each cutting stroke, the blade is lowered a predetermined amount. The feed pump may also be actuated by the rocking of lever 29 reciprocating slide member 26, the lever being rocked by cam 33 engaging follower 32. Different cams 33 according to the crosssection of the workpiece may be provided to vary the feed. The differential valve 41 is adjustable to control the pressure with which the saw blade engages the workpiece.

Patent ES-373026-A1 (ES)
Title: Adjustable bearing means for a disc brake
IPC: F16D55/2265
Filed: 1969-10-30
Abstract: The caliper housing 34, Fig. 2, straddling the disc 12 of a disc brake, is mounted for sliding movement of a predetermined amount relative to two pins 74, Figs. 1 and 4, each pin 74 being itself mounted for sliding movement, in certain circumstances, relative to an arm 30 or 32, Fig. 1, of a torque-taking member 10 located on the inboard side of the disc 12. The torquetaking member is secured to a fixed spindle 24. The " predetermined amount" above referred to is represented by spacings A1B1 and A1C1, Fig. 4, provided between the ends of a pin 74 and the effectively-closed ends of the bores 84 in which the pin-ends slide. Any normal lateral disc displacement during non-braking conditions will move the housing 34 transversely with respect to the disc faces, taking up space A1B1 or A1C1 on each pin. This movement takes place freely. On normal brake application, the reaction movement of housing 34 (upwards in Fig. 4) brought about by admission of brake fluid at 56, to chamber 52, Fig. 2, is relative to the pins 74, and is sufficient to take up some or all of space A1C1, Fig. 4. If lining 66 becomes sufficiently worn for space A1C1 to be exceeded, the housing 34 engages the appropriate ends of pins 74 and moves them transversely relative to arm 30 or 32 as the case may be, this movement being resisted by sliding contact with leaf springs 92, 96, Fig. 1, described below. This movement is an automatic wear-compensating movement. Pin 74 on the right of Fig. 1 is held in groove 88 of arm 30 of torque-taking member 10 by leaf spring 92 secured at 94 to member 10. Owing to manufacturing tolerances the pin 74 on the left is held away from the base of groove 90 of arm 32 by an amount C1D1. Pin 74 on the left is held up by leaf spring 96, secured at 98 to member 10, and shown with its free end broken away: the free end turns inwards horizontally and supports pin 74 above the end of groove 90 by an amount E1F1 owing to manufacturing tolerances. With reference to friction element 68 on the right of Fig. 2, the diameter of piston 44 and bore 46, and the dimensions of seal 48 and bore 50 are so chosen that on normal brake application the piston 44 in being forced to the left merely stresses seal 48 without sliding within it. On release of fluid pressure, seal 48 recovers its shape, moving piston 44 to the right to its former position. If lining 72 of friction element 68 becomes worn, piston 44 slides in seal 48 during brake application until the wear distance has been automatically compensated for. On pressure release, recovery of seal 48 moves piston 44 to the right slightly. A rubber boot 54, Fig. 2, seals the open end of cylinder bore 46, and seals 100, Fig. 4, are provided in grooves 102 to prevent entry of dirt. Friction element 58, Fig. 2, is removably attached to the radial portion 38 of housing 34 by inserting integral projections 60 into openings 62.
