Title: Improvements in steering mechanism for vehicles
IPC: B62D5/06
Filed: 1933-05-02
Abstract: 410,965. Motor vehicle steering-gear. BENDIX-WESTINGHOUSE AUTOMOTIVE AIR BRAKE CO., Pittsburg, U.S.A. May 2, 1933, No. 12764. Convention date, May 3, 1932. [Class 79 (v).] Comprises power-operated steering gear in which a lever 10, Fig. 1, or 43, Fig. 4, controlling the power is pivoted relatively to a powertransmitting steering lever 12 or 49 characterised in that the relative movement of the levers is limited by the shaft on which the steering lever is supported. In the construction shown in Figs. 1 and 2 the hand-operated steering shaft 4 rotates the lever 10 by means of known gearing comprising a worm or cam 7 and a roller 8. The lever 10 is pivoted at 13 on an arm or lever 12 fixed to a shaft 5 which is connected by a drop arm 6 to the stub axles. One end 11 of the lever 10 loosely encircles the reduced end of the shaft 5 so as to allow limited oscillation of the lever 10 on the arm 12. A gear segment 18 integral with the arm 12 engages a rack 24 connected to pistons 22, 23 working in cylinders 20, 21 operated by pressure fluid, such as air, admitted from pipes 25 and controlled by valves 26, 27 operated by collars 38, 39 journalled on the boss 11 of the lever 10. Each valve unit comprises an inlet valve 29 and an exhaust valve 30 rigidly connected and controlled by a spring 37 which normally closes the valve 29 on its seat 32 while leaving the exhaust valve open so that the respective cylinder is connected to the atmosphere. When the shaft 4 is rotated the lever 10 rocks about the pivot 13 and the boss 11 moves relatively to the shaft 5 so that valve rod 41 (say) is moved to the right. This rod is attached to a plunger 34 having an exhaust bore 35 ; as this plunger moves to the right it compresses a spring 37 and seats on the exhaust valve 30 which closes the bore 35. Further movement of the plunger opens the inlet valve 29 which admits air through pipe 36 to cylinder 20 so that piston 22 moves to the right and rocks the segment 18 and shaft 5, thereby steering the road wheels. The rocking movement of the segment 18 and arm 12 causes the boss 11 of lever 10 to move to the left back to its central position so as to close valve 29 and open 30 unless the shaft 4 is continuously rotated. When the lost motion between the shaft 5 and the boss 11 is taken up the driver's effort assists the power cylinder, and at the same time the resistance to steering reacts on the hand-operated shaft so that the driver can " feel '' the steering. The valves are operated against the pressure of the springs 37 ; if these are weak the gear is almost entirely poweroperated, if strong the gear is hand-operated when the resistance is small, power being used only for great resistance to steering. In the construction shown in Fig. 4 the hand-operated shaft rotates an arm 42 connected by a link 45 to a lever 43 which is pivoted at 48 on the power transmitting lever 49 and has a boss loosely encircling the shaft 47 on which the lever 49 is mounted. Collars 62, 63 journalled on the boss of the lever 43 operate the valves 29, 30 of the power device.

Filed: 1964-03-26
Abstract: Ammonium phosphate (NH3:H3PO4=0.8:1 to 2.1:1), which may contain up to 20% (NH4)2SO4, is prepared by reacting phosphoric acid containing less than 60% P2O5 with NH3 gas under super-atmospheric pressure, to give a fluid ammonium phosphate solution at its boiling point containing 4-15% water, and expelling the solution into an ambient pressure zone where it loses H2O, to form a solid product. NH3 may be passed into phosphoric acid containing 30-55% by weight P2O5, and which may be mixed with H2SO4, at a pressure of 15-50 lb./m.2 giving ammonium phosphate containing 2-10% water. The soln. may be expelled into a prilling tower, or on to a conveyer belt provided with a flail-type flaker, or on to particulate solids, e.g. fertilizers and/or recycle material, and then granulated by agitation in a rotating drum or paddle mixer. Fertilizer granules may be prepared by expelling the soln. into the ambient pressure zone with a concentrated soln. of NH4NO3, and/or by spraying the soln. on to particles of fertilizer materials, e.g. NH4NO3, (NH4)2SO4, triple and single superphosphates KCl, K2SO4, KNO3 and potassium phosphates. Example 2 discloses a fertilizer formed by spraying 1 part of the ammonium phosphate soln. and 2-33 parts NH4NO3 soln. on to 0.7 parts KCl and 5 parts of recycled undersize or oversize ammonium phosphate.

Title: New or improved transfer devices for articles
Inventor: OAKLEY FRANK
IPC: C21D1/64
Filed: 1963-04-03
Abstract: <PICT:0987338/C6-C7/1> <PICT:0987338/C6-C7/2> <PICT:0987338/C6-C7/3> For transferring articles 10 through a quenching bath 14 of oil an elevator comprises article-supporting members 12 carried on diametrically opposed sides of a tubular shaft 23.  Each member 12 comprises a perforated platform or grid 25 having a back wall 26 and side walls 27 extending above and below the platform or grid. The shaft 23 is mounted coaxially on a shaft 20 which is of square cross-section over most of its length and mounted in bearings 21. The elevator may be raised and lowered along the shaft 20 by a fluid pressure operated cylinder 33 connected to a bearing assembly 30 of the shaft 23 by chains 31.  The tubular shaft 23 has bushes 29 having square internal cross-section so that the elevator is prevented from rotating relatively to the shaft 20.  For rotating the elevator, together with the shaft 20, through 180 degrees, a pinion 34 on the shaft is rotatable by a rack 35 operated by a fluid pressure device 36.  Limit switches or mechanical linkages (not shown) ensure that the rack and pinion can be operated only when the article supporting member is in the bath and the elevator is at or near the lower end of its travel. The tank 14 is closed by a top wall 18 provided with an entrance aperture 16 and an exit aperture 17 provided with ducts 19, 15 respectively.  Evaporation and deterioration of the liquid is thus minimized.  An impeller 37 and a conduit 39 cause the liquid to circulate and to flow through the article-supporting member 12 when the latter is at a station C, Fig. 2.  In operation, an article 10 is moved by a pusher 11 from a furnace on to the member 12 which is situated at a station B.  The elevator is then lowered until the member 12 is in register with the end of the conduit 39 at station C. The impeller 37 is then operated and after the treatment has been completed, the elevator is rotated through 180 degrees so that the member 12 carrying the article 10 is at station D.  The elevator is then raised to bring the article into a delivery station E from which it is removed.  A drain tray 40 is provided and a tunnel similar to the tunnel 19a formed on the entrance duct 19 may be provided.  Such an exit tunnel may be supplied with a reducing atmosphere.  The entrance tunnel 19a may be provided with a prepared atmosphere such as one produced by endothermic or exothermic reaction between air and a fuel; cracked ammonia or nitrogen &c.  The elevator may be made to rotate through 360 degrees and there may be four or more article supporting members. The invention is applicable to other operations such as spraying, washing or cleaning.
