Title: Vehicle-steering arrangement
IPC: B62D6/00
Filed: 1976-01-09
Abstract: 1525072 Steering systems DAIMLER-BENZ AG 9 Jan 1976 [17 Jan 1975] 0800/76 Heading B7H Steering gear, which may or may not be power assisted, wherein the steered wheels are deflected in relation to both the angle of deflection and the rate of deflection of the steering wheel. A steering shaft 13 carries a screw 31 meshing with a rotationally fixed but axially movable ring member 34. Arms 37 on the member 34 are connected to cylinders 38 of hydraulic shock absorbers whose piston, rods 42 are pivoted to arms 43 of a sleeve 41 which is rotatably mounted but axially fixed on a further sleeve 46. The sleeves 41, 46 are together axially movable relative to the steering shaft, sleeve 46 being rotatable with the shaft through meshing splines 54, but sleeve 41 being rotationally fixed relative to the shaft. Sleeve 46 carries members 57 which engage a helical groove 58 on a shaft 59 fixed to the input 26 of the steering gear 25. In operation rotation of the steering wheel 10 causes the shaft, via splines 54, to rotate sleeve 46 whose motion is transmitted via members 57 and groove 58 to input 26. Rotation of screw 31 with the steering shaft 13 causes axial movement of ring member 34 and cylinders 34. The resulting axial movement of the pistons and rods 42 displaces sleeves 41, 46 axially against a biasing spring 49, this motion being transmitted as rotary motion to input 26 via members 57 and groove 58. As the speed of rotation of the steering wheel is increased the damping effect of the cylinders 39 will become greater and the motion superimposed by axial movement of sleeves will increase. Hence, the deflection at input 26 is dependent on both the angle and the rate of rotation at the steering wheel. The steering wheel is mounted on hub 12 by a collapsible pot 11.

Title: An improved process and apparatus for the manufacture of artificial silk
IPC: D01D10/04
Filed: 1933-01-10
Abstract: <PICT:0411952/IV/1> <PICT:0411952/IV/2> In a continuous process for the production and treatment of artificial threads, each individual thread is guided in a helical path on one or several continuously surfaced rotating rollers and is subjected thereon to treatment with liquids.  It is then dried while passing in a plurality of windings round rotating heated drying cylinders and is finally wound on a winding or twisting spool.  The wet treatment may be carried out with stretching or shrinking of the thread; for this purpose the rollers may be constructed conically and mounted horizontally and the liquid may be sprayed on the thread and caused to travel in counter-current to the thread.  The surfaces of the rollers may be perforated, grooved, or corrugated, and the rollers may be overhung from bearings at one side only.  Drying may be carried out in stages between which the thread is remoistened.  As shown in Fig. 1, a thread 1 issuing from a stretch-spinning apparatus 2 is led through a channel 3 and treated with acid.  It then passes in a helical path round a rotating roller 5, the different windings being kept apart by hooks 12.  The roller 5 dips into a vessel 8 supplied with water which travels in counter-current to the direction of progression of the thread.  The thread is then passed in a helical path round a heated drying roll 13, the temperature of the roll being maintained by means of steam, gas flames, or circulating hot oil.  The thread is finally wound on a spool 18. As shown in Fig. 2, the thread 1 is passed in helical manner round a conical roll 5 and sprayed with water, desulphurizing liquid, or other treatment liquid.  The decreasing diameter of the roll in the direction of travel of the thread compensates for the shrinkage which occurs.  If desired the roll may be oppositely disposed in order that the thread may be stretched during the treatment.  The thread passes round part of a heated drying cylinder 13 in helical fashion and after preliminary drying is remoistened by means of a wet roll 20.  It then passes in helical fashion round the larger surface 13<1> of the drying cylinder and is dried in stretched condition.  It is finally twisted and wound.  The wet roll 20 may moisten the thread with water, size, soap solution, or softening agents.  If desired, the treatment rollers may be supported vertically and the treatment liquid may be supplied tangentially. Specification 394,217 is referred to.
