Title: Improved method of and apparatus for treating oil
IPC: C10G7/00
Filed: 1928-07-03
Abstract: 318,700. Foster Wheeler, Ltd., (Foster Wheeler Corporation). July 3, 1928. Hydrocarbons, distilling.-Lubricating oil fractions with small overlapping of fractions from the viscosity standpoint are produced by progressively heating stock oil such as crude petroleum or relatively heavy residues to a maximum temperature in a. tubular oil heater with such rapidity or for such a short period of time as substantially to avoid the cracking which would occur if the oil were heated to the same temperature more slowly, and then treating the oil in a fractionating tower in which the condensates formed in the upper portion of the tower from vapours liberated in the lower portion thereof are subjected to intermittent contact with steam and with vapours passing up through the tower. Separate fractions are withdrawn from the tower at different levels and the character of these fractions is regulated by variably passing descending liquid about the sections of the tower. The heater comprises an oil furnace A having one bank of tubes exposed to radiant heat and two banks heated solely bv convection and separated by a bank S', S<2> in which steam is superheated. The oil vapours pass through a pipe C to the base of a tower D where they mix with the superheated steam which enters by a pipe S<3> and the mixed vapours and steam pass up the tower through bubble trays E and inverted funnel shaped members L. Adjustable devices associated with alternate trays permit of some or all the condensate being withdrawn from the tower through outlets H, and pipes H<2> may connect two outlets H to bye-pass part of the tower. The members L divide the tower into sections and each collects such condensate as is present in its section ready for removal from the tower by pipes M<1> - - M<4>. These pipes each include a liquid seal M<5> and supply heat through exchangers O<1> - - O<4> to the incoming oil. Specification 270,720 is referred to.

Abstract: 1279821 Weapon systems TRW Inc 15 April 1969 [16 April 1968] 19306/69 Heading F3C A method of feeding ammunition rounds 14 to a gun in succession from an elongated storage bag 12 in which a plurality of the rounds 14 are arranged side-by-side in a row in which the bag 12 is drawn through a bag-splitting station 16 where the bag is progressively split open along a pair of longitudinally extending parting lines to release the rounds in succession from the bag, the split portions of the bag being drawn away from the bag-splitting station along divergent paths on opposite sides of the released rounds to draw the bag through the splitting station. The apparatus for carrying out the method comprises a pair of driven rollers 28, one at each side of the path of movement of the ammunition, the path of movement being defined by a feed shoot 34 and each of the two parts of the split bag passing over a respective one of the rollers. A solenoid operated pressure roller 48 is associated with each of the rollers 28 such that, on actuation of the solenoid, the roller 48 is urged towards its associated rollers 28 to form a nip for the corresponding part of the split bag and thus feed the bag through the bag-splitting station. The bag may be formed with perforations along its two narrow sides to facilitate splitting. Clutch driven take up reels may be provided for winding up the parts of the split bag and driving the bag and in this case bag slitting members are provided in the feed shoot (Figs. 10 to 13, not shown). The apparatus is shown in a weapon system and to this end the feed shoot projects beyond the bag-splitting station to adjacent a pocketted transfer wheel 214. The ammunition 14 is fed successively into the pockets 216 of the wheel and guided for movement therewith by a resiliently mounted guide 218. Transfer cams 224 are interposed between the transfer wheel 214 and a breech cylinder 204 of an open chamber gun so that rounds are stripped from the transfer wheel 214 by the cams 224 and fed successively to open chambers 206 of the breech cylinder. The gun and the feed mechanism are driven by a motor directly and through gearing respectively. The feed shoot 34 is associated with a storage box 66 in which the bag may be stored in layers (Figs. 7, 8b, not shown) or in a plurality of spirals (Fig. 8a, not shown). The part of the feed shoot to the rear of the bag-splitting station 16 is rigidly fixed to the storage box 66 and is connected at its forward end to the forward portion of the shoot by coupling pins (Fig. 6, not shown).

Abstract: 1,081,514. Electro-physical measurements. VARIAN ASSOCIATES. May 12, 1965 [June 4, 1964], No. 20116/65. Heading G1N. The invention relates to automatic homogenity control in a gyromagnetic spectrometer having a probe 10 containing the unknown sample and a reference material (e.g. 1% tetramethyl silane), excited by an R. F. generator 14 to produce a spectral signal which is fed to a phase detector 18 providing audio output. Correcting Field Drift This output is passed to A. F. phase detectors 24, 36 and compared with phase controlled signals from A. F. generators 26, 34 operating at e. g. 2 kc/s and 3 kc/s to provide absorption and dispersion peaks. In operation the dispersion signal is used to control the field/frequency ratio if the polarizing field or frequency of the R. F. generator drifts causing the operating point to move from the zero position as illustrated in Fig. 2 (not shown). Optimizing Field A further A. F. phase detector 42 is set to operate in the absorption mode, and its output is compared in an L. F. phase detector 48 with a signal from an L. F. generator which tends to modulate the supply to the shim coils 40 causing periodic changes in field gradient at the probe which periodically broadens the absorption peak from shape A to shape B Fig. 3 (not shown). The resultant output from the phase detector 42 and hence L. F. phase detector 48 operates the current control 52 to produce resonance lines having the greatest amplitude. Modifications. Fig. 5 (not shown) separate current controls may be used for each pair of shim coils. Fig. 7 (not shown) the control may be applied by a "sequencer" alternately to the shim coils and the "curvature coils" 80.
