Abstract: 1513604 Elevation propelling mechanism EATON CORP 17 Aug 1976 [20 Aug 1975] 34096/76 Heading B8L An hydraulic system controlling rams 16, 18 for lifting a load carriage 14 of a lift truck comprises a load responsive shut-off valve 42 for directing pressurized fluid to both rams when the carriage is heavily loaded and to only one ram when the carriage is lightly loaded, whereby the lighter load can be elevated faster. Fluid from a fixed displacement pump 36 passes to a manually set direction valve 40 which when set in a raise condition, passes the fluid to both working chambers 76, 88 of the two rams, the line to the chamber 88 including the shut off valve 42 controlled by a pilot line 108 responsive to the fluid working pressure. The valve 42 is normally closed whereby all the working fluid passes to the ram 16, until a predetermined line pressure, proportional to the load being carried, is exceeded whereby the valve 42 is opened and both rams are supplied. The piston 86 of the ram 18 is formed as a fluid reservoir 96 and has an opening 120 to the chamber 88 closed by a non- return valve 120 whereby fluid bleeds from the reservoir 96 into the chamber 88 during non- pressurized extension of the ram 18 to prevent cavitation in the chamber 88. A non-return venting valve 106 at the top of the reservoir 96 assists flow from the reservoir 96 to the chamber 88. In the neutral position of the control valve 40 fluid is supplied directly to the reservoir 96 and upon back pressure therefrom, the fluid flows to tank 34. In the load lowering position of the valve 40, fluid from the two chambers 76, 88 and from the pump 36 is directed to the reservoir 96 and 34.

Title: An improved process for the manufacture of fertilisers
IPC: C05B7/00
Filed: 1947-12-29
Abstract: In making fertilizers by treating tricalcium phosphate with nitric acid and ammoniating the resulting products, there is introduced into the process, before ammoniation, a complementary amount of phosphoric acid such that the total amount of this acid present is at least equal molecularly to the amount of calcium nitrate present, ammoniation resulting in the total decomposition of the calcium nitrate with formation of ammonium nitrate and dicalcium phosphate. The additional phosphoric acid which may be in excess of that required to make up the molecular amount necessary, may be added to the products of the reaction of nitric acid and crude phosphate or before the addition of the nitric acid to the phosphate. Furthermore, the additional phosphoric acid may be in the form of the product obtained either by the action of sulphuric acid on natural phosphates or nitric acid on superphosphate.  Ammonia may be introduced in gaseous form, diluted if desired, as a concentrated solution or as ammonium carbonate or sesquicarbonate, the carbon dioxide evolved being used in producing ammonium carbonate. Potassium salts and/or salts containing nitrogen may be added to the mass during or after its manufacture.  The Specification as open to inspection under Sect. 91 comprises also the use of ammonium and/or potassium salts to replace part of the additional phosphoric acid. This subject-matter does not appear in the Specification as accepted.

Abstract: 484,509. Curtain - rail brackets. HARRISON, S. C. Dec. 18,1936, Nos. 34807 /36 and 1017 /37. [Class 52 (v)] A bracket a for securing curtain rails in position is made in one piece of tubular, channel or like form and provided at or near its outer end with a pair of similar oppositely disposed slots b for receiving the flanged edge c of the rail d, and a firing screw f inserted longitudinally through the bracket acts on the outer end of the bracket to set up a binding action on the rail. As shown in Fig. 1, the screw has a conical portion h which expands the outer end of the channel-shaped bracket a and causes the slotted parts to grip the rail. A separate conical bush may be used, and the bracket may be bent to tubular form. Fig. 6 shows a modification in which slits i are formed at the inner ends of the tee-slots and the head g of the screw bears against the outer end of the bracket to cause the rail to be gripped between the end and main parts of the bracket. The end of the bracket adjacent to the wall may be restricted to form a guide for the screw as by forming indentations j, Fig. 10 in the side walls, and flanges k may be provided to give a broad bearing surface on the wall. The shank of the screw may bear upon the upper surface of the rail while the head engages an inclined part of the upper wall of the bracket, the rail being thus gripped between the screw shank and the slots.
