Title: Improvements in or relating to tractors
IPC: F16H37/00
Filed: 1961-12-14
Abstract: 927,028. Tractor power take off. H. ALVIK. Dec. 14, 1961 [Dec. 14, 1960], No. 44873/61. Class 79(2) [Also in Group XXIV] A transmission gear incorporating a power take-off for a tractor, especially a walk-type tractor, comprises an engine-driven input shaft 10, an output shaft 11 for driving the tractor wheels, a shaft 12 rotatably mounted on the shaft 10 and integral with gears 13 and 14, gears 22 and 23, the latter having internal teeth, fixed to the shaft 10, a gearset 15 comprising the gears 16 and 17 rotatably mounted on the shaft 11 and a gearset 21 comprising the gears 19 and 20 axially slidable but non-rotatably mounted on the shaft 11. The shaft 12 may be brought to the position shown in which position the gearset 21 may be brought to positions whereby the gear 19 engages the gear 13, or the gear 20 engages the gear 14, so providing two output speeds of the shaft 11 through the routes 22, 16, 17, 13 and 19 or 22, 16, 17, 13, 14 and 20. By shifting the shaft 12 to the right so that gear 14 engages the internally toothed gear 23 locking the shafts 10 and 12 together, two more speeds are obtained by engaging the gears 19 and 13 and the gears 20 and 14. The gearshift mechanism comprises the elements 31 and 32 having claws 33 and 35 respectively, slidable on a shaft 30 located in a vertical plane intermediate the shafts 10 and 11 and formed on a hollow lever 46 and a bell crank lever 36, respectively, the latter being pivoted to an arm 38 integral with the member 31 and operated through a shaft 40 and eccentric 42 keyed to a shaft 43 rotated by a handle 45. By moving the lever 46 about a pivot 47 the shaft 12 is slid on the shaft 10, the gearset 21 participating simultaneously with the movement, and by rotating the handle 45, the gearset 21 is brought to its two positions relative to the shaft 12. The shaft 12 may also be brought to an intermediate neutral position. A power take-off shaft 50 is rotatably mounted on the shaft 11 and is provided with splines 51 upon which slides a splined sleeve 53 having internal teeth 54 which may be brought into engagement with either a gear 55 secured to the shaft. 11 or teeth 56 provided in the gearset member 15 or to a neutral intermediate position, with the aid of a sleeve shifting member 59. The power takeoff shaft 50 can thus be driven independently of the tractor wheels from the shaft 10 through the route 22, 16, 56, 54, 52 and 51 or, by engaging the teeth 54 with the gear 55, at the same speed as the wheel driving shaft 11.

Title: Metallizing and bonding non-metallic refractory bodies
IPC: H01B1/00
Filed: 1966-10-07
Abstract: 1,128,228. Brazing. GENERAL ELECTRIC CO. 7 Oct., 1966 [18 Oct., 1965], No. 45017/66. Heading B3R. [Also in Divisions C7 and H1] A material, for metallizing or bonding non- metallic refractory bodies, e.g. either together or to a metal, in wire, rod or powder form, comprises composite metal particles having a core of an active metal selected from Ti, Hf, Th, Zr, V, Ta, W or mixtures or alloys thereof, coated with a brazing metal selected from Ag, Cu, Au, Ni, Fe, Mo, Cr, Pt, Co, Sn or mixtures or alloys thereof, wherein the proportion of active metal to brazing metal is greater than that in the lowest melting eutectic thereof. For example, composite metal particles 10-50 microns in size, comprising 85% Ti powder of 325 mesh (44 microns maximum) size and 15% Ni coating deposited by a fluidized bed process, are applied, e.g. by painting, spraying, silk screening, flow coating or dipping, in a suitable vehicle, e.g. toluene and amyl acetate solvent with iso-butylmethacrylate and nitrocellulose binder, to a non-metallic refractory body such as forsterite, which is then heated in a non-reactive atmosphere to above the lowest melting eutectic temperature of the Ti-Ni alloy to effect bonding. Areas desired to be metallized, such as a printed circuit pattern, may be provided with carbon residue material, e.g. from nitrocellulose solution in amyl acetate. The resultant residual carbon may react with the active alloy, e.g. to form a ductile Ti-Ni-C compound.

Title: Method of quantitative analysis
IPC: G01N27/00
Filed: 1974-10-24
Abstract: 1486621 Quantitative analysis PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 24 Oct 1974 [27 Oct 1973] 46028/74 Heading G1N A constituent of a fluid is determined by passing the fluid and a reference fluid alternately for equal periods T through a cell which exhibits an exponential output/time curve with a step change in input and determining the constituent from the resulting sawtooth signal. The time T is less than (e.g.1/6) of the time for the cell output to steady at   a new value following an input change. The reference fluid is preferably prepared from the constituent containing fluid by removal of the  constituent. In Fig. 3, the dotted line shows the cell response to an input change from So to S 1 , the reading being steady after about 3(t 1 -t 0 ). When the unknown and reference fluid are alternately  applied for a period T = ¢ (t 1 -t 0 ) the sawtooth results. The constituent concentration is determined by finding the sum of the integrated value of the sawtooth during and the first half of the second period (T n ) and A times the integrated value during the second half of the first period (T ni ) and also the sum of the integrated value during the second half of the second period and A times the integrated value during the first half of the first period, where 0 # A # 1. The difference between these sums is a measure of the concen tration. As shown in Fig. 4, gas containing a constituent is supplied direct via line 23 or after removal of the constituent at 22 via line 25 to selector 9 which, under control of clock 20 connects the line 23, 25 alternately to measuring cell 6. The gas is moved through the cell by suction pump 12. The cell outputs 14, 15 are processed at 16 and fed to recorder 19. Reference gas from 11 may be supplied either before or after selector 9 so that the cell operates on a desired part of its output curve. In an alternative embodiment, the reference gas input is at 25 and the reference gas flow is adjusted in response to the cell output until the sawtooth amplitude is minimized, the position of the adjuster thus being a measure of the constituent concentration.  A system for determining NO and NO 2  in air is also described and details for using the cell with m input unknowns and measuring over m + 1 periods T are given.

Title: Method for removing traces of nitrogen oxide from coke oven gases
IPC: B01J8/18
Filed: 1964-12-02
Abstract: Nitrogen oxide is removed from coke oven gases by entraining active carbon in a stream of the gases and subsequently separating the carbon from the purified gas.  The removal is carried out at low temperature (temperatures as low as - 65 DEG  C. are mentioned) and the carbon is regenerated by air, nitrogen, or by purified gas, preferably at a high temperature (temperatures up to 200 DEG  C. are mentioned) in a separate column.  The carbon is continuously cycled between the regenerating and purification zones. Five specific examples are described.ALSO:Traces of nitrogen oxide are removed from coke oven gas by causing the gas to carry along particles of active carbon which are recycled after regeneration in a closed circuit in the presence of air, nitrogen or the heated, purified gas. Adsorption of nitrogen oxide on the carbon may be carried out at low temperature (a temperature of -65 DEG C is mentioned in one example) and regeneration may be at temperatures up to 200 DEG C.
