Title: Process and Apparatus for Purifying Oils.
IPC: C10G25/06
Filed: 1917-09-25
Abstract: 118,353. Marks, E. C. R., (Swan Process Oil Co.). Sept. 25, 1917. Mineral oils, purifying; recovering waste lubricants.-Relates to a process for refining oils, applicable for example for reclaiming waste lubricating oils, and comprises the treatment of the oil with kieselguhr or like diatomaceous earth and subsequent filtration; the oil so purified may be distilled to remove volatile impurities and thereafter again treated with the kieselguhr &c. and filtered. In the plant shown, impure oil from a tank A is pumped to a heated tank B wherein it may be treated with reagents and allowed to settle, and passes thence to a tank C wherein it is washed with water. The tank C is provide with baffles 37, 39, Fig. 2, an oil outlet 42, and a water over. flow 41 at a lower level. The oil is next agitated in a tank D with kieselguhr which may be supplied as a mixture with clear oil from a tank E. From the tank D the mixture passes to a filter F from which the clear oil passes to a tank G; or oil may be withdrawn directly from the tanks B or C to the tank G. The oil is pumped from the tank G to a tank H supplying a still K. The residual oil from the still passes to a tank N and may be retreated with kieselguhr in a tank D' and passed through a filter F<1>. The order of the tanks C, D may be reversed.

Title: Improvements in wagon-tipping apparatus fitted with weighing-apparatus
IPC: G01G19/04
Filed: 1933-05-16
Abstract: 415,537. Weighing apparatus fitted to wagon-tipping apparatus. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, and MARSHALL, C. H., Fraser & Chalmers Engineering Works, Erith, Kent. May 16, 1933, No. 14165. [Class 143.] In a combined wagon-tipping and weighing apparatus a weigh lever of the weighing- apparatus is arranged below the cradle of the tipping apparatus and means are provided for varying the relative positions of the fulcrum of the weigh lever and the point of the lever through which the load is transmitted to the weighing means, whereby the weight of a wagon is transferred from the cradle to the weigh lever. As shown a lifting frame 4 is arranged below a rotary tippler of known form comprising wagon-receiving beams 1<a> and annular members 3. The lifting frame is supported on weigh levers 13 fulcrumed on links 14 suspended from lifting levers 15, the weigh levers being connected to a weighing machine by a link 25. The outer ends of the lifting levers are pivoted on supports 10 and the inner ends rest on cams 18 revolvable by an electric motor. The lifting frame 4 is connected by links 5, Fig. 3, and toothed levers 6 to lifting pads 11 pivoted upon a frame 8 normally resting on fixed stops 9. In using the apparatus the motor is set in motion and the cams 18 raise the inner ends of the lifting levers 15 thereby raising the weigh levers 13, lifting frame 4 and links 5. The links rotate the lifting pads 11 into the vertical position shown in which position heels 23 on the lifting pads abut against the frame 8. Further rise of the links 5 then carries the frame 8 and lifting pads vertically until the lifting pads engage the wagon wheels 12 and raise the wagon in which position the whole weight of the wagon is taken by the weighing machine. In a modification, the pivoted lifting pads 11 and links 5 are dispensed with and the lifting pads are built in rigidly with the lifting frame 4, the lifting pads at one side engaging the flanges of the wheels whilst those at the other side engage the treads in order to avoid fouling the pads as the tipping apparatus is rotated.

Abstract: 572,511. Detectors. GENERAL ELECTRIC CO., Ltd., BRITTAIN, F. H., and RANSLEY, C. E. Nov. 5, 1941, No. 14267. [Class 40 (v)] [Also in Group II] A crystal detector is assembled by the following method. A crystal is fixed in one end cap of an insulating tube, a second cap carrying the contact device being then attached to the other end of the tube. The contact is adjusted and then fixed in position, and the assembly sealed. The ends 6 of the insulating tube 5, Figs. 4, 6, are coated internally with metal, and it is then attached with fusible alloy to the brass cap 7 standing on the hotplate 12, Fig. 4. The crystal 1 is attached with adhesive 4 to the end of a rod 2, and its exposed surfaces coated with a metallic layer; it is then introduced on the rod 2 into the molten alloy 11 contained in a depression 10 in the cap 7. The hot-plate 12-is rapidly cooled, and when the alloy 11 has set, the rod 2 is detached and removed. The face of the crystal thus exposed is polished. This assembly is now attached to a second cap 13, Fig. 6, which supports a movable rod 16 carrying the whisker contact 17 welded to its upper end. The cap 13 stands on a hot-plate 19, and the open end of the tube 5 fits into a groove 15 containing fusible alloy. The assembly is connected into an electrical testing circuit, the rod 16 adjusted for satisfactory performance, and the hot-plate 19 then rapidly cooled. The rod 16 is held in position by alloy 20 which has overflowed from the groove 15. Finally, the assembly may be filled with wax, through a hole 21 in the tube 5, using a vacuum process. A modification is described using a crystal with plane faces, in which case it may be attached directly to the top of the cap 7 before the tube 5 is attached. The process for coating the crystal 1 with copper is described, and consists in dipping it in a solution of cuprous oxide in hydrofluoric acid. Coating of the insulating tube is performed either by using a proprietory solution, or by reduction of deposited cuprous oxide in hydrogen, or by placing an annulus of copper within the tube and heating.

Title: Salts of ª-hydroxy-1:2:5:6-tetrahydrobenzylphosphonous acid and a process for their manufacture
IPC: C07F9/48
Filed: 1956-05-09
Abstract: The invention comprises salts of a -hydroxy-1 : 2 : 5 : 6 - tetrahydrobenzylphosphonous acid with organic bases of the general formula <FORM:0835737/IV (b)/1> in which R1 and R2 represent a hydrogen atom, a halogen atom, e.g. chlorine or bromine, a nitro group or an alkyl or alkoxy group containing 1 to 4 carbon atoms, R3 is an alkylene group containing a maximum of 3 carbon atoms and R4 and R5 represent a hydrogen atom or an alkyl group containing a maximum of 4 carbon atoms, or an aralkyl or cycloalkyl group, or together with the nitrogen atom represent a heterocyclic ring, and the salts of which with hydrohalic acids are relatively sparingly soluble in water.  They may be obtained by heating, preferably at 70-90 DEG  C., 2 to 3 molecular proportions of hypophosphorous acid of 40 to 60% strength with 1 molecular proportion of 1 : 2 : 5 : 6-tetrahydrobenzaldehyde for not more than 2 hours, and mixing with the reaction mixture so obtained an organic base of the above formula, the said base being preferably used in a proportion amounting to at least one equivalent with respect to the quantity of the aldehyde.  The salt is obtained in crystalline form and can be decomposed by treating it with a solution of an equivalent quantity of an alkali in the presence of an organic solvent which is immiscible with water to give an alkali metal salt of a  - hydroxy - 1 : 2 : 5 : 6 - tetrahydrobenzyl - phosphonous acid.  The free acid may be obtained from the salt by acidification, e.g. by acidifying an aqueous solution of the salt.  An example is given for the production of the o  - butylaminoacetic acid - 2 - methyl - 6 - chloranilide salt of a -hydroxy-1 : 2 : 5 : 6-tetrahydrobenzyl phosphonous acid and its conversion to the sodium salt by treatment with an aqueous solution of caustic soda in the presence of benzene.  The conversion of the sodium salt to (a) the free acid by acidification of an aqueous solution of the salt followed by extraction with ethyl acetate and (b) to the calcium salt by treating an aqueous solution of the salt with an aqueous solution of calcium chloride are also described.  Other organic base salts specified are the o -butylaminoacetic acid 2-methyl-3-chlor- (and brom-) anilide salts, the o -butyl-amino-acetic acid-4-methyl-3-bromanilide salt, the o -butylaminoacetic acid-2 : 6-dichloranilide (and -2 : 6-dimethylanilide) salts, the o -butyl-aminoacetic acid - 2 0 methyl - 5 - methoxyanilide salt, the o -butylaminoacetic acid-2-methylanilide salt and the o -benzyl-amino-acetic acid (and -propionic acid) anilide salts. The sodium salt of the phosphonous acid is a strongly active tonic (see Group VI).ALSO:A tonic comprises an aqueous solution of the sodium salt of a -hydroxy-1 : 2 : 5 : 6-tetrahydrobenzyl phosphorous acid (see Group IV (b)).  Other substances which may be present are vitamins, e.g. ascorbic acid or Vitamin B1, hormones and adenosine.
