Abstract: 483,848. Gravity-separation apparatus. HARTLEY, E. Nov. 12, 1936, No. 30886. [Class 111] The float-supported upper end of a pivoted pipe 12 through which the supernatant liquid is withdrawn from a settling-tank has one or more side inlet openings at the upper end guarded by a box or boxes 22 which prevent the entry of scum. In the arrangement shown the liquid enters the pipe through spigot pieces 17 and the boxes 22 are attached to rings 21 which swivel on the spigot pieces. The upper ends of the boxes are adjustably connected by screwed rods 25 to a bridgepiece 24 attached to floats 23. The rate at which the liquid is withdrawn is controlled by means of caps 19 with suitably sized apertures 20 which are screwed on to the spigot pieces 17. The caps may have a longer barrel with outlet holes in the side walls and may incorporate a conical block projecting into the spigot pieces, so that the effective passage therethrough can be regulated by screwing or unscrewing the cap. The pipe 12 is connected by a swivelling elbow 13 to a pipe 10 passing through the wall of the tank.

Patent GB-622495-A (GB)
Title: Improvements relating to the treatment of laundry and the like trade effluents
IPC: C02F1/52
Filed: 1946-10-23
Abstract: A process for the treatment of laundry and other soap-containing trade effluents comprises adding washed precipitated aluminium or iron hydroxide, hydrated oxide or oxide, dried or in the form of a slurry, either alone or admixed with an alkaline-earth carbonate to effect the precipitation of the dissolved soap and/or to effect the coagulation or de-emulsification of the suspended matter, screening or filtering or both, and conducting the whole operation under such conditions as to conserve heat.  The aluminium or iron hydroxide, hydrated oxide, or oxide is prepared by precipitation from a solution of an aluminium or iron salt with an alkali metal, alkaline earth, magnesium or ammonium oxide, hydroxide, carbonate or bicarbonate. The resulting precipitate is washed with water to remove the alkali, alkaline earth, magnesium or ammonium ions, and used as a wet or dried and powdered concentrate, or made into a slurry. Addition to the laundry effluent first causes precipitation of the dissolved soap, coagulation of this precipitate and of suspended matter resulting when excess is added.  Alkaline earth compounds such as magnesium oxide, hydroxide, or carbonates may be added before or with the aluminium or iron hydroxide.  The reaction vessels are heat-insulated so that only a small drop in temperature ensues during the process.  According to one example a hard paste of aluminium hydroxide is prepared from solutions of aluminium sulphate and sodium carbonate followed by filtration and washing.  From the paste a slurry is formed with water, and 100 parts of the slurry containing one part aluminium oxide is added to 10,000 parts laundry effluent, avoiding excessive agitation, the resulting liquor being filtered through stainess steel cloth. In another example 50 parts chalk slurry containing a half part of calcium carbonate are added to 70,000 parts laundry effluent, and 50 parts aluminium oxide slurry containing a half part aluminium oxide are added, followed by the step of filtration.  In a third example magnesium basic carbonate is added to a slurry of ferric hydroxide made from ferric chloride and a lime suspension, the resulting slurry containing equal parts of ferric hydroxide and magnesium basic carbonate.  100 parts slurry containing a half part of each constituent are added to 10,000 parts laundry effluent, followed by filtration.  In all the examples the temperature drop is from about 65 DEG C. to about 50 DEG C.  The filter residue may be treated with sulphuric acid to yield insoluble fatty acids for re-use as a soap stock, and soluble aluminium sulphate from which the hydroxide may be prepared for re-use.

Abstract: 146,783. Andreau, J. E. Dec. 16, 1919. Addition to 133,286. Variable-speed epicyclic gearing described in the parent Specification as modified by the first addition and comprising eccentric masses such as g<1>, g<2>, Fig. 11, upon planet spindles such as e', e<2> is further modified by the use of double-acting " selectors " or pairs of ratchet clutches, so as to utilize reverse as well as forward impulses. Thus a driven shaft f, Fig. 3, carrying a fly-wheel p picks up forward impulses through a ratchet clutch q directly, and reverse impulses through a clutch i and a reversing train of bevel-gearing r, s. The eccentric masses may be arranged in groups in different phases, each group in same phase having a separate pair of " selectors," as shown in Fig. 11. Thus a shaft f<1> drives a shaft f through a clutch q<1>, or through clutch i' and reversing train r<1>, s, or a shaft f<2> in different phase may drive forward through clutch i<2> and train w, or through clutch q<2> and reversing-train r<2>, s.

Abstract: 787,996. Electromagnetic relays. TELEPHONE MANUFACTURING CO., Ltd. Oct. 31, 1955 [Nov. 2, 1954], No. 31655/54. Class 38 (5). In a relay in which the contact springs 11, 12 are mounted in a support 10 as disclosed in Specification 728,891, each moving spring 12 (only one shown) engages a slot in an operating bar 13 by means of a cylindrically-shaped end and co-operates on either side of the bar 13 with the twin contacts of fixed springs 11. The cylindrically-shaped end resiliently engages the opposed sides of the slot and manufacture of the bar 13 is facilitated owing to the greater width of the slot required to accommodate the enlarged spring end. The fixed contacts 11 may have cylindrically-shaped free ends, or they may be formed of rod or wire.

Abstract: 508,457. Lifting motor vehicles. HANSEN, A. G. K. Nov. 2, 1938, No. 31701. [Class 78 (iii)] A motor vehicle is raised at one end for repair by a hydraulic ram 3, Fig. 5, applied direct to one axle, the other axle remaining on its road wheels on the ground. The cylinder 1 is sunk in the ground and connected to a source of compressed air by a pipe 5 fitted with supply and blow-off valves 6, 7 respectively. The piston is guided at the upper end of the cylinder by a sunk casting 4 which can be covered by a flat plate when the apparatus is not in use. The piston may be locked in the raised position by a headed pin 13, Fig. 2, a pivoted pawl 15 Fig. 3, or by a pair of friction grips acting on opposite sides of the rod with a toggle-action. In the case of the pin, the head 13 passes below the level of the adjacent surface of the member 4 when the shank 12 rests on it, thus preventing axial withdrawal until the rod has been raised to release the head.

Abstract: 797,558. Mass spectrometers. SLEPIAN, J. Nov. 8, 1955 [Nov. 18, 1954], No. 31880/55. Class 39(1). Isotopes in an arc discharge between electrodes 35, 37, Fig. 1, are projected radially by a low intensity electric field set up by ring electrodes 45, 47 and are separated by a combination of circumferential D.C. electric fields produced by radial plates 71, 75 and an axial magnetic field produced by magnet N.S. The arc is isolated by radial or circumferential overlapping plates 67, 69 which float electrically relative to the arc. Overlapping segments 61, 63 and 61<SP>1</SP>, 63<SP>1</SP> may also be provided top and bottom of the apparatus. It is stated that space-charge neutralizing electrons are projected with the ions. Rings 45, 47 serve also to confine electrons axially. It is shown by analysis that in Fig. 5 ions tend to move outwardly in the spaces between radial plates 73 and 77 and between radial plates 71 and 75, and that heavier ions are drawn towards the negative plates and lighter ions towards the positive plates. In the spaces of negligible thickness between the plates 71 and 73 and between the plates 75 and 77 ions move inwardly. In modifications the radial plates may be subdivided into sections 73a. 73b, 73c, 73d at increasing potentials, Fig. 7, a pair of radial plates 201, 203 only may be used, Fig. 6, or sector plates 61, 63 and 61<SP>1</SP>, 63<SP>1</SP> may be used in place of radial plates, Fig. 8.
