Title: Power-assisted steering arrangements
IPC: B62D5/06
Filed: 1971-04-19
Abstract: 1316231 Power assisted steering DAIMLER BENZ A G 19 April 1971 [28 Feb 1970] 22273/71 Heading B7H In a power assisted steering unit having a servo motor reinforcing the manual effort which is controlled by a slide valve 10, "feel" is produced by a reactive pressure acting between the control valve spool 28 and a reactive piston 34 or 35 mounted in a reactive space 32 or 33 in the spool. The spaces 32 and 33 always connect, through bores 36 and 37, with the delivery lines 19D and 20D to operating chambers 19 and 20, and the pistons comprise first and second parts 39 and 43 loaded by springs 45 and 50 which abut a member 46, 47 contacting the valve body 38. Spring 45 bears against part 39 whilst spring 50 bears against both parts. The spool 28 is moved through a radial arm 25 on the nut 15 of a worm and nut 16, 15 connected through shafts 17, 18 to the steering wheel when the force of its centring spring 51 is overcome, the nut 15 being mounted within an operating piston whose toothed exterior 21 engages the teeth 22 of a rocker bar 24. On moving the spool to connect 19D or 20D to the supply line 30, space 32 or 33 is pressurized and, at low steering, an opposing reactive force equal to the product of the supply pressure and the combined end face area of the parts 39, 43 acts on the spool, the springs 45, 50 being uncompressed. At higher steering part 39 abuts a ring 44 on the spool thus reducing the reactive pressure, and at even higher steering the part 43 abuts the end face of part 39 and is itself supported by the spool thus reducing the reactive pressure still further. At this point further deflection of the spool is opposed only by the force of springs 45 and 50. In a further embodiment (Fig. 3, not shown) the pistons are constructed so that the springs (45a) and (50a) each act individually on the piston parts (39a) and (43a).

Title: Improvements in or relating to clutch mechanism
IPC: F16H3/38
Filed: 1923-09-05
Abstract: 224,986. Alexander, F. H. Sept. 5, 1923. Operating clutches and toothed wheels. - In means for engaging clutches and toothed wheels without shock, applicable to locomotive boosters, &c. snrew-and-nut means are adapted to interengage when the speeds of the clutch &c. parts are substantially identical, and axial movement of the screw or nut releases locking-means, thus allowing the clutch &c. to be engaged under spring, manual, or power pressure. In Figs. 2 and 7, the gear-wheel 5' to be engaged with a wheel 4, is secured to a drum 26, in which is splined a nut 17 provided with part-threads 16 adapted to coact with similar threads 15 on a screw member 27. The wheel 5<1> is splined to slide on the shaft 2 and the screw 27 carries wheel 28 similar to the wheel 5<1> and gearing with the wheel 4. When the speeds of the parts 17, 27 are substantially different, the screw threads cannot engage, but when the part 17 is slowly over-running the part 27, the, threads 16 can pass helically through the threads 15. If, at this time, axial pressure is applied' by hand or power upon the collar 28<1>, the wheel 5<1> is actuated and engages the wheel 4 as the threads disengage. The gear ratio of the wheels 4, 28 may be such that the velocities of the wheels 4, 5<1> are equal during the engaging-action. Springs 29 connecting the parts 26, 17 allow the wheel 5<1> to be disengaged from the wheel 4 when desired, the teeth 16 passing through the teeth 15 to allow the nut 17 to follow the wheel 5<1> when the nut is rotating slightly more slowly than the screw 27. Fig. 1 shows a modification in which a wheel 6 is pressed by a spring 10 towards engagement with a wheel 4, but is restrained both by a collar 23 removable by hand or power and by a collar 21 connected by a link 20 and lever 18 to the automatic screw-and-nut control on a shaft 2 driven by the wheel 6. The nut member 17 is splined on the shaft 2 and the screw member 14 is driven by chain gearing 13 from the wheel 4 so that the velocities of the screw and nut are equal when those of the wheels 4 and 6 are equal. Provided the collar 23 is out of restraining position, the spring 10 engages the wheels 6, 4 when the collar 21 is permitted to move towards the wheel 6 by the action of the screw-and-nut control. A spring 25<1> returns the teeth 16 through the teeth 15 when conditions permit. Fig. 3 shows a construction in which the wheels 5', 4 may engage when either of the screw-and-nut controlling-members over-runs the other. The screw member 27<1> is splined upon a sleeve 29 secured to the shaft 2 and tends to be placed by internal springs midway between the wheel 28 and a flange 29<1> on the sleeve 29. so that the teeth 16 engage midway with the teeth 15. A cam 30 on the member 27<1> is adapted to lift a lever 31 from the path of a stop 34 on a rod 35 moving with the gear-wheel operating-collar 36. The cam lifts the lever 31 so that the gear wheel can be moved, whichever way the teeth 16 are passing through the teeth 15. Specification 126,194 is referred to.

Title: Improvements in activated carbon manufacture
IPC: C01B32/336
Filed: 1944-11-14
Abstract: <PICT:0591060/III/1> Activated carbon is prepared by passing hot activating gas diluted with hot inert gas amounting to at least half of the gases at a pressure greater than atmospheric into and through a compact body of finely divided particles of carbon, all the thermal requirements of the reaction being supplied by the sensible heat of the gases.  The inert gas may consist of the products of the reaction, e.g., carbon monoxide or hydrogen, and the pressure may be at least 5 lbs./square inch greater than atmospheric.  As shown, char to be activated trickles down refractory checker-work 14 contained in an upright metal retort 10 lined with refractory heat insulating material 12.  Activating gas is obtained by burning natural gas in a burner 15 in a combustion chamber 16. The resultant gas (comprising carbon dioxide, steam, and nitrogen) may be heated or cooled as required by tubes 20, 21, 22 and 23, and passes through passage 25 to manifold 26 in the retort. Activated carbon is removed from discharge 30 and gaseous reaction products through outlet 31.  Alternatively, steam diluted with reaction products may be used as the activating gas.  In this case, the reaction products (carbon monoxide and hydrogen) are scrubbed, passed through a booster, mixed with steam, and the mixed gases passed through a coil type superheater before being passed to the retort.  In another modification, burnt natural gas as the activating gas is mixed with water gas which has been passed through a scrubber and a booster.  Quantitative examples are given, in which the temperature of the gas entering the retort is given as being between 1380 DEG  and 1900 DEG F., and the charge temperature as being between 1320 DEG  and 1640 DEG F.

IPC: A61F2/50
Filed: 1919-09-15
Abstract: 136,512. Bocksberger, O. Sept. 15, 1919. Limbs, artificial.-A foot, which pivots on the leg and moves angularly under the control of front and rear buffer springs during the act of walking, is fitted with means for setting it at varying angles with respect to the axis of the leg, and also with means for controlling the amplitude of the ankle movement. Thus, the rotation of the cam e, through the instrumentality of a Bowden wire, rocks the bridge c and positions the bolts d<1>. This movement causes the buffer springs to act against the bridges d<3>, pivoted to the foot, and swivel the foot until it is inclined forwardly or rearwardly, as the case may be, while still leaving it free to oscillate under the control of the springs in the act of walking. It is intended that the foot should be adjusted with a forward inclination for walking uphill, and with a backward inclination for walking downhill. To vary the amplitude of the ankle movement, the cam c may be moved axially against the action of a spring to vary the amount of play between the stops c<2> and the cam. Fig. 5 shows a modified form in which the spring rods and the bridge are replaced by a curved blade spring r.

Title: Tape and a process of making same
IPC: B31F1/00
Filed: 1921-08-29
Abstract: 187,776. Gates, B. W., and Plymouth Cordage Co. Aug. 29, 1921. Bands.-A tape made of paper &c. is formed with flattened and integrally connected rolls at each edge thereof, as shown in Fig. 6. The tape may be manufactured by a continuous process, in which the raw material a, Fig. 1, drawn from a supply roll and over a tensioning-roll, passes over a guide-roll 15, through a die 16, and, if desired, through a former 21, to compression and draft rolls 17, 18, after which it is spooled. The paper strip is started through the die by rolling the corners until it is small enough to pass through the die, and thereafter the draft on the other side of the die causes the rolling of the edges b to progress steadily along the strip. As each portion of the strip reaches the die, the rolling ceases and the rolled edges become crushed edgeways so as to produce longitudinal wrinkles and to break up the stiffness of the material. The rolls 17, 18 flatten the material and fix it by forming sharp creases in the laminated edge rolls, and the tape acquires a permanent set. The former 21 mounted on a spring 22 and pressing on the roll 18 has a tapered groove 21<1> therein, which crowds the abutting convolution of the tape into and past each other, and also limits the edgeways expansion due to the pressure of the rolls 17, 18. The paper may be treated with adhesive or with waterproofing, insulating, or other compound, preferably applied before the strip reaches the roll 15. Threads 23, Fig. 8, mav be located in the edge rolls, and are fed therein during the rolling thereof. The threads 23 can be replaced by wires, whereupon the tape can serve as a twowire electric conductor.
