Title: Planetary gear accessory drive
Inventor: FLINN GEORGE EARL
IPC: F16H37/00
Filed: 1960-10-21
Abstract: 961,674. Driving external apparatus. BORGWARNER CORPORATION. Oct.21, 1960, No. 36270/60. Heading B7H. [Also in Divisions F1 and F2] A simple sun gear-ring, gear-planets, train driving accessories in a motor vehicle is arranged to give an overdrive ratio when the vehicle is stationary. The accessories may include an electrical power generator, an engine cooling fan, an engine cooling water pump, a pump for supplying fluid pressure for power steering, and a compressor for the vehicle air conditioner or air springs. In one form, an internal combustion engine 11, Fig. 1, drives through a transmission 13 which may include an hydrokinetic torque converter and multi-ratio mechanical gearing (not further described) to an output shaft 15. A flexible drive 54 connects the output shaft 15 through belt-and-pulley gearing 44 to the ring gear 16, Fig. 2, of a planetary train 10, the ring gear meshing planet pinions 18 mounted in a carrier 19 fast for rotation with the engine crank-shaft 12. The planet pinions 18 also mesh a driven sun gear 17 driving through belt-and-pulley gearing 48, 49 to accessories 56, 58. The arrangement is such that with the vehicle and the output shaft 15 stationary, the ring gear 16 is stationary, and the planetary gearing 10 gives a step-up ratio, but with increasing vehicle and output shaft speed, the ratio falls to approximately direct drive. In a modification, a similar planetary gear has a geared drive 59, Fig. 4, to its carrier from the engine crank-shaft 12 and a geared drive 52, 53 from an intermediate shaft 76 between an hydrodynamic torque converter 62 and a changespeed bear to its ring gear, the sun gear driving through a shaft 61 to the engine accessories. In a similar modification, Fig. 3 (not shown), the ring gear is geared to the output shaft 15 instead of to the intermediate shaft 76.

Filed: 1920-12-31
Abstract: 156,171. Urbasch, O. Dec. 28, 1919, [Convention date]. Connections to carbons; absorbents. - The depolarizing mass 1 which also forms one electrode of a cell of the Leclanche type is formed with one or more chambers 3 for the reception of the eleclyte and zinc electrode 5 by means of a mould and wedge-shaped cones. The cell is covered with a shell 6 of impermeable material such as paper treated with paraffin, or varnished, which is introduced into the mould as a lining. The mould is then filled with manganese depolarizer and wedge-shaped cores are forced in to form the chambers. Current is taken from the depolarizing mass 1 by carbon rods or by plastic leads 2 consisting of compressed powdered graphite or carbon mixed with paraffin, pitch, ozokerite or other water-repellant substance. Metallic cores 7 separated from the depolarizer 1 by insulating rings 9 may be embedded in the leads 2. The leads 2 are made by placing a mixture of paraffin and graphite, for example, on the bottom of the mould before the depolarizing material is introduced. After the depolarizer with the leads have been removed from the mould and dried the chambers 3 are filled with a pasty electrolyte containing ammonium chloride and the perforated sheet zinc electrode 5 inserted. A paper or fabric bag 10 separates the electrodes. The cell may be filled with solid electrolyte and a.n absorbent such as blotting paper, gum tragacanth &c., water being introduced through an opening 11 when the cell is required for use. The spent depolarizer may be regenerated for further use. The Specification, as open to inspection under Sect. 91 (3) (a) states that the depolarizer may be shaped by moistening it with electrolyte and pressing it into moulds provided with cores and then drying. This subject-matter does not appear in the Specification as accepted.

The apparatus may provide means to produce a signal proportional to the speed of movement of the material and an integrator arranged to integrate the signal proportional to speed over the time the material is passing through the apparatus means to multiply the output of the integrator by a signal representing width of the material to give a signal representing area. This is applied to an analogue to digital converter that produces a pulse train of frequency proportional to the input signal. The pulse generator may comprise an apertured disc, rotated by the material drive motor or otherwise; that transmits light from a light source periodically on to photo-conducting elements to produce a pulse train.

Title: Process and apparatus for the production of concentrated nitric acid
IPC: C01B21/26
Filed: 1965-09-08
Abstract: Nitric acid (e.g. of at least 70% concentration by weight), as produced from ammonia and air in a process wherein the ammonia is oxidized by combustion with air under a pressure of at least 3.5 atmospheres absolute, the combustion gases are cooled initially to about 160 DEG  C. and finally in a condenser to a temperature at which at least 75% by weight of water vapour contained therein is condensed, the gases remaining in the condenser for less than one second, the nitrogen oxides in the cooled gases are oxidized to nitrogen peroxide and the nitrogen peroxide is further oxidized and absorbed by passage through aqueous solutions of nitric acid of different concentrations in a multi-stage absorber; the entire process being carried out without any further compression of the gases other than at their point of entry to the process. The initial cooling may be in two steps, first to about 260 DEG  C. and then to about 160 DEG  C.  The final cooling of the gases e.g. to 40-70 DEG C. may be carried out in a vertical multi-tubular condenser through the tubes of which a cooling fluid such as water is passed.  The oxidation of the nitric oxide gases to nitrogen peroxide may be carried out in a column with horizontal perforated plates on which an emulsion is produced by the passage of the gases through an aqueous solution of nitric acid contained on the upper surfaces of the plates, the nitric oxide gases condensed in this column being sufficient to supply the plates and form the emulsion, excess solution from each plate passing to the plate below. Cooling coils may be immersed in the emulsion on the plates.  The absorption and further oxidation may be carried out in one or more columns fitted with horizontal plates provided with openings or perforations whereby the gas can pass through the plates and into contact with aqueous solutions of nitric acid of different concentrations carried on the upper surfaces of adjacent plates, the points at which the solution arrives at each plate being in a straight line parallel to the longitudinal centre line of the column and the points at which the solution leaves the plates being situated in another straight line parallel to the centre line near the edge diametrically opposite to the arrival points, the solution flowing from each plate to the one below through a pipe transverse to the longitudinal centre line of the column.
