Title: Power steering for motor vehicles
IPC: B62D5/24
Filed: 1973-06-12
Abstract: 1415959 Power steering AUTOIPARI KUTATO INTEZET 12 June 1973 27955/73 Heading B7H  Steering is power-assisted by a double-acting piston 2 having a rack 3 formed on its skirt and slidable within a cylinder 1 divided by the piston into upper and lower chambers 7, 8. A rotatable slide valve 15 is fitted within the piston 2 and threaded to a steering spindle 16, such that rotation of the spindle effects sliding movement of the valve to supply fluid under pressure through a bore (21), Fig. 2 (not shown), or bore (22) to the chamber 7 or 8, Fig. 1, respectively, thus causing movement of the piston upwardly or downwardly. A channel 19 connected to bores 24a and 26 is connected selectively to the bores (21) or (22) depending on the direction of rotation of the spindle 16. A tube 24 journalled in piston cover 13a is sealed by packing 25 in the bore of spindle 16. In operation, the valve 15 is open until spindle is turned, so that both pressure chambers 7, 8 are connected with the outlet channel 20 for return to the pump reservoir. Upon rotation of spindle 16, the valve is displaced to stop flow between channels 19 and 20 so that pressure is supplied to one or other chamber 7 or 8 to displace the piston 2. Due to an annular space 13 communicating the chamber 8, the pressure of the chamber 8 affects the annular part of the piston encircling the tube 24. The small size of the packing 25 around the tube 24 reduces frictional losses.

Title: Improvements in or relating to metal covered shafts, rollers or the like
IPC: D21F1/40
Filed: 1938-09-27
Abstract: 503,667. Making cased shafts or rollers. STEVENS, A. H. (Watson, C. G.) Sept. 27, 1938, No. 28117. [Classes 83 (ii) and 83 (iv)] [Also in Groups VIII and XXIV] Uniting by fusion.-In coating steel, cast iron or other metal shafts or rollers with nickel, stainless steel, or the alloy sold under the Registered Trade Mark "Monel," a number of sheet metal segments of the desired metal are fitted on the roller &c. with their longitudinal abutting edges in planes parallel or oblique to the axis and are pressed in successive longitudinal sections into intimate contact with the roller &c. and the edges in such sections then welded while under pressure. A pair of segments 4, Fig. 3, may be held on a solid or hollow shaft &c. by the correspondingly shaped dies of an hydraulic press 5 and may be first tack welded at 7, the assembly being advanced across the dies between each operation. The seams are subsequently completed by fusion welding, the weld metal on cooling drawing the sheets into close contact with the core. Preliminary tack welding may be dispensed with, and the pressure may be effected by grooved rollers through which the work is passed continuously. A series of pairs of sections may be welded on the core, the abutting ends being welded at 9. In the case of sections of different lengths with oblique ends, the ends also are welded. A hollow shaft may be cooled by flowing water therethrough. Metal sleeves 21 provided with welded caps 23 may be applied to the bearings 3 and welded to washers 22 also welded to the coating 4. The sides of the core may have longitudinal grooves 10 containing inserts 11, which may consist of coating metal or may be of Monel metal when the coating metal is nickel. The welding of the edges is effected over these inserts so as to keep the seam free from contamination by the core metal. When using three segments, the press has three separate jaws 34, one for each segment. The seams may all be welded between the jaws at each advance or staggered welding may be effected, one seam being first welded the full width of the jaws and the others to shorter lengths, the assembly being then shifted until the jaws embrace the section adjacent the shortest weld, which is then continued for the full width of the jaws and so on. For an assembly with two seams and jaws of width a-c, welds are first effected between the jaws at a-b and a<1>-c<1> and the jaws then, advanced to b-d, whereupon seam b-d is welded. The jaws are then advanced to c-e, and the seam c<1>-e<1> welded and so on until the position f-h is reached when seams f-h and g<1>-h<1> are welded. Parts of the roller &c. may be coated with welded sheets and the rest with rubber or other non-metallic material.
