Title: Tractor having a hydraulic lift system
IPC: A01B63/112
Filed: 1973-06-08
Abstract: 1407667 Tractor power lift mechanisms FORD MOTOR CO Ltd 8 June 1973 [28 June 1972] 27318/73 Heading A1P A tractor has a system for control of implement hitch so that the position control lever 51 may be set to establish implement height below which the implement will not move regardless of the implement draft selected on lever 37. The two levers operate on the same quadrant 39 and control co-axial inner and outer shafts to cranks 49 and 35. The hitch is hydraulically operated by fluid supplied to cylinder 10 via valve 19 with spool 20 biased by spring 21 to the hitch lowering position. Draft Control Draft is sensed on the spring loaded plunger 31 and fed to the mid-position of draft control servo lever 34 by telescoping link 44. Lever 34 is pivoted on shaft 24 and draft control lever 37 with crank 35 predetermines amount of compression of spring 32 to position valve spool 20 in the neutral position. Movement of plunger 31 either side of selected setting by alteration in draft will be fed to lever 34 which will pivot with crank 35 acting as fulcrum and result in movement of spool 20 and hence raising or lowering of the hitch. Position Control Hitch rack shaft 16 has position control cam 46 which actuates position control servo lever 47 through torsionally sprung levers 52 and 54. Lever 47 is also pivoted on shaft 24 and the upper end is positioned by crank 49. Movement of lever 51 rocks the top of lever 47 about the engagement point with lever 52 which is positioned by control cam 46. This results in the movement of the lower end of lever 47 and hence valve 19 to the raise or lower position. Tractor Operation In operation if the draft decreases sufficient to cause valve 19 to lower the hitch below that selected by the position control lever 51. the position control takes precedence and the upper end of the draft servo lever 34 will disengage from the crank 35. To operate. solely in draft control the position control lever 51 may be pushed to its lowest position to permit linkage lowering to its full limit.

Abstract: 1390105 Gas discharge display panels FU. JITSU Ltd 13 June 1972 [21 June 1971 18 Sept 1971] 27514/72 Heading H1D In a gas discharge display device having electrode arrays 3 and 4 formed on the glass substrates 1 and 2 and covered with dielectric layers 5 and 6, the latter are coated with thin layers 7 and 8 which include an alkali metal element, an alkaline earth metal element, or lead, to increase the secondary electron emission of the surfaces and thereby reduce the firing voltage. The dielectric layers 5 and 6, between 0À1 and 20 microns thick, are formed of a material-e.g. alumina, silicon dioxide, or silicon nitride-which is relatively unreactive with alkali metal to permit, in manufacture of a device employing the latter as the emissive material, the formation of a uniform alkali metal layer over the whole area of the device, after sealing the two substrates together around their edges, by evacuating the envelope so formed through an exhaust tube located at one corner of the device (11, Fig. 12, not shown), and introducing the alkali metal, either in vapour form or in solution, through a fill tube (12) located at the opposite corner. The secondary emissive layers 7 and 8 are less than 100 Angstroms thick, and hence form discontinuous layers whereby the surface resistivity is maintained. In a modified structure (Fig. 1A, not shown), the electrode arrays are covered with layers of a low-melting point glass to which the dielectric layers and secondary emissive layers are subsequently applied.

Title: Package and method of packaging perborate-containing products
Inventor: MEEK HOMER VIRGIL
IPC: B65B55/19
Filed: 1969-05-30
Abstract: 1,223,514. Packaging. PROCTER & GAMBLE CO. 30 May, 1969 [4 June, 1968], No. 27582/69. Heading B8C. A method of packaging a product which generates nascent oxygen, such as one containing perborate, comprises locating the product in a carton formed of cartonboard which contains a source of borate ions, the quantity of the source being at least 160 parts by weight, calculated as boron, per million parts by weight of cartonboard of which at least 80 parts have been applied to the outer surface of the carton. The source of borate ions is preferably boric acid or an alkali metal borate, the preferred materials being boric acid, borase, sodium metaborate or a mixture thereof. Potassium borates, or ammonium borate however may be used. The cartonboard can be treated by applying a boron compound solution to the cartonboard web by a drum coater, size press, or water box on the board machine, or by adding a solution of boric compound to the materials used for coating or sizing the cartonboard. Alternatively, a printing press or coating equipment can be used to apply the boric compound solution. The cartonboard can then be converted into cartons by ordinary methods of manufacture, and the filling can be carried out by wellknown automatic, or semi-automatic, machines. Five examples, with tabulated results of carbon treated with borate ions to prevent "mottling" of the carton, are described.

Title: Manufacture of oxalates and oxalic acid
IPC: C07C51/41
Filed: 1920-10-06
Abstract: A mixture of alkali oxalate, alkaline earth hydroxide, and water is agitated in a closed vessel and treated with carbon monoxide, or gases containing carbon monoxide, preferably under pressure and at temperatures above 100 DEG  C.; the alkaline earth oxalate is separated from the solution of alkali formate produced and the latter evaporated and converted by heat into alkali oxalate for use in the first stage of the process.  In an example the treatment of a mixture of sodium oxalate and calcium hydroxide is described.  Oxalic acid is obtained by treating the alkaline earth oxalate with sulphuric acid. In the conversion of alkali formate to oxalate, the former may be first melted at 270 DEG  C. and then run into a decomposition vessel preheated to 440 DEG  C., agents for increasing the yield being added if desired.  In order to economize lime and sulphuric acid the sodium oxalate may be first freed from sodium carbonate by any known means, for example by washing with water; the solution of sodium carbonate so obtained may be treated with the necessary quantity of lime and then with carbon monoxide to yield further formate and oxalate.
