Abstract: 1,046,201. Power assisted steering. ZAHNRADFABRIK FRIEDRICHSHAFEN A.G. Jan. 21, 1964 [Jan. 24, 1963], No. 2628/64. Heading B7H. A power-assisted steering apparatus comprises a power cylinder 40, a control valve housing 14 and a housing 18 accommodating a ball-pin 104 arranged coaxially and connected to one another to form a unit, the ball-pin 104 being connected to the drop arm 8 of a steering mechanism, the housing 18 being connected to the steering linkage 10, and the connecting rod 26 of the power piston 25 being articulated to the vehicle at 27. The control valve spool 50 is connected to the seating arrangement 91, 92, 101, of the ball-pin, which has limited movement in the housing 18 whereby the valve is actuated. The valve spool is acted upon by a centering spring 95 in a compartment 94 which receives pressure fluid through a passage 96 from the pressure fluid supply line. The power cylinder is supplied on the side 31 through a passage 60 and the annular space between the cylinder 12 and the housing 40, and on the side 30 through a passage 61 from the grooves in the valve housing under the control of the spool 50. A passage 59 is connected to reservoir. The valve bore 48 is separated from the cylinder space 30 by a cap member 81 having a sealing ring 82, and an axial bore 86 in the valve spool drains adventitous liquid from the space 84 into the ball-pin housing where it acts as a lubricant before escaping.

Title: A new or improved separating mechanism for use with conveyors, particularly in root harvesters
IPC: A01D33/02
Filed: 1949-02-05
Abstract: 670,706. Potato harvesters. WHITSED, W. J. Jan. 16, 1950 [Feb. 5, 1949], No. 3245/49. Class 6(iii) [Also in Group II] A potato or beet harvester has an endless conveyer 1 of the chain web type by which the roots together with attached haulm and rubbish are discharged on to a travelling riddle 2 encircling at least the top lap of transverse horizontal conveyer 3. The riddle comprises two endless side chains 4 mounted on rollers 5, 6, 7, 8 and driving sprockets 9, the chains being connected by cross-bars 10. The cross-bars 10 comprise rods 11 fixed to the chains and tubes 13 mounted freely on the rods carrying rigid arched tines 14 sufficiently long to overlap the next succeeding bar 10. Thus the upper lap of the riddle is more or less rigid while as the bars 10 pass around the upper rollers 7 the tines 14 rotate to hang downwardly on the lower run, thereby discharging any material clinging to them. As the tines enter the horizontal lap they pass over a horizontal frame member 15 which removes any remaining material. An inclined screen 16, which may be slotted or reticulated is placed beneath the upper lap of the riddle to guide potatoes falling through the riddle. The tines instead of being mounted to pivot simultaneously, e.g. by welding to the tubes 13, may be individually pivoted.

The helical element may be a single wire or a plurality of wires in side-by-side relationship. There may be a grip enhancing material on the inner surface of the helical element. The mid-portion 12b may be preformed to provide an inner diameter more than the diameter of the line but less than twice the diameter of the line. The end helix portions 12a, 12c may have their axes offset relative to each other. The tail portion of the bent back portion preferably extends beyond the helical element to permit attachment thereto of a line tensioning device and said tail portion may subsequently be secured in position by a lashing.

Abstract: 1462851 Preparation of pulverulent vinyl chloride polymer compositions RHONE-PROGIL 28 Jan 1974 [2 Feb 1973] 3758/74 Heading C3P Pulverulent compositions based on homo and/or co-polymers of vinyl chloride and comprising fusible solid additives and liquid additives (including additives present in solution) are prepared by mixing in aqueous medium; the liquid and at least part of the solid additives being introduced into the mixing zone in the form of at least one dispersion of a homogeneous phase in water. The composition is then separated and dried. In Example 1 a single homogeneous phase containing epoxidized soya oil, zinc and calcium stearate, alphaphenylindole and glycerol monostearate is converted into a homogeneous phase by heating at 110 C. and dispersed in an aqueous solution of neutralized maleic anhydride styrene copolymer as dispersing agent. This dispersion is mixed with an aqueous polyvinyl chloride emulsion and powdered polyethylene wax and thereafter a graft polymer of styrene and methyl methacrylate on polybutadiene is added. The mixture is heated prior to extraction and drying. In other examples the procedure is generally similar but the homogeneous phase contains: (7) dioctyl tin bis-isooctyl mercaptoacetate, oxidized polyethylene wax and glycerol trihydroxystearate; and (8) stearic acid, cetyl palmitate, glycerol monostearate and oxidized polyethylene wax. The dispersing agent may be (7) sodium dioctylsulphosuccinate and (8) methylcellulose. Other materials separately introduced into the mixing zone are (5) butadiene/acrylonitrile on polyvinyl chloride graft polymer, aqueous calcium chloride, polyvinyl chloride latex; (7) colouring mixture of oxidized polyethylene wax and dye; (8) vinyl chloride/vinyl acetate copolymer suspension, an aqueous TiO 2 /polyethylene wax/ lead sulphate dispersion, graft polymer as in (5), aqueous calcium chloride and polyvinyl chloride latex; (9) and (8) omitting the graft polymer; (10) as (1) omitting the graft polymer; (11) an aquous polyethylene wax/lead sulphate/lead phosphate mixture; (15) butadiene/acrylonitrile grafted on to polyvinyl chloride, polyethylene wax.
