Title: Improved emulsion for coating, impregnation and sealing purposes
IPC: C08L95/00
Filed: 1938-02-21
Abstract: 515,198. Emulsions ; coating compositions. DEUTSCHE ERDOL-AKT.-GES. Feb. 21, 1938, Nos. 5459 and 5460. Convention dates, Feb. 20, 1937, and Feb. 22, 1937. Drawings to Specification. [Classes 1 (i) and 95] Bituminous emulsions having an aqueous continuous phase and prepared with known emulsifying agents, 'e.g. alkali resin soaps, are characterized by the use of unsaturated bituminous substances which are free, or have been freed, from saturated oily constituents and from substances capable of being precipitated by chloroform. Suitable bituminous 'substances are asphalt extracted from mineral oils and tars according to Specification 479,488, pitches from low temperature distillation, or distillation from flushing gas and products thereof after removal of highly cracked constituents, residues from pressure splitting of tar distillates. The substances may be treated with air. They may be used in admixture with flux oil (tar oil and the like), and with addition of wax, paraffin, resin, fatty pitch. The emulsions may be freed from coarser particles, e.g. of more than 5 Á diameter. Coatings are produced by applying the emulsions and blowing warm air on the coated surface. The emulsions may be used for coating brown coal briquettes. Specification 486,932 is referred to.

Filed: 1951-03-07
Abstract: 690,844. Centrifugal machines SHARPLES CORPORATION. March 7, 1951 [March 18, 1950], No. 5514/51. Class 23 A method of operating a sludge valve 24 of a centrifuge comprises applying centrifugal force to the moving parts of the valve to close it and developing an opposing centrifugal force :in a column of liquid to open the valve, the discharge of liquid from the column being effected separately from the discharge of sludge from the centrifuge. The auxiliary liquid is fed to the valve through a pipe 25 and is controlled by a valve which is manually operated or controlled by a timing mechanism. The auxiliary liquid is supplied through a spray ring 28 into a cup 29 which is secured to the centrifuge rotor 11 and has fins 29b. The valve 24 has a piston 24b which has a skirt portion sliding in liquid tight engagement with a wall 32 of the valve and defines a, chamber 40 therein. The valve seating 21b is removable and made of wear-resisting material. When the valve is open, the excess auxiliary liquid is discharged through an orifice 33. The pipes 25 arewelded or brazed to T-shaped tubular members 67 of rectangular cross-section which are anchored by a plate 65. The cross arms of the members 67 are disposed adjacent the spindle 14 of the centrifuge whilst the legs are disposed in radial grooves formed in a ring 69. Specification 543,508 is. referred to.

Title: Improvements in monovalve filters
IPC: B01D24/46
Filed: 1962-02-13
Abstract: 927.667. Filters. UNION TANK CAR CO. Feb. 13, 1962 [Aug. 30, 1961], No. 5534/62. Class 46. A filter of the self-backwashing type comprises a filter tank 1, at least one filter chamber 2 containing a filter bed 5, e.g. sand, a backwash storage compartment 11 in communication with the outlet side 2b of the chamber through at least one connecting duct 10, an inlet pipe 22, a filtered liquid outlet 12, a backwash outlet pipe 23, and a transfer conduit 6 in communication at its one end with the inlet side 2a of the chamber and in common communication at its other end with the inlet pipe and the backwash outlet pipe. Means for automatically controlling the backwash cycle comprises a butterfly valve 18 for controlling the flow of liquid through the backwash outlet pipe, an electrical actuating means 17 for opening and closing the valve, a high level control pipe 14 in communication with the inlet side of the chamber and incorporating a high level sensing switch 15 electrically connected to the actuating means 17, whereby lqiuid rising to a predetermined height in the pipe, due to clogging of the filter bed 5, and contacting the switch, causes the valve to open thereby initiating the backwash cycle, and a low level sensing switch 19, having a probe 20 disposed in the compartment 11, which is electrically connected to the actuating means 17, whereby liquid in the compartment falling below a predetermined level excites the switch 19 thereby causing the valve to close and end the backwash cycle. Scrubbing of the backwashing storage compartment may be assisted by the introduction of compressed air into the compartment. An underdrain compartment 9 is situated below a false bottom 3 of the tank which is fitted with strainers 4. Reference is made to a filter tank having two or more filter chambers, such that one filter bed can be backwashed while the other chambers are being used for filtering in which event the continuing flow of filtered water from the latter chambers assists in the backwashing of the chamber being cleaned. The invention is applicable to water filtration.

Patent GB-781936-A (GB)
Title: Purification of terephthalic acid
Inventor: TAYLOR ARTHUR WILLIAM CHARLES
Filed: 1955-02-25
Abstract: Crude terephthalic acid containing impurities other than p-toluic acid, such as p-acetyl benzoic acid, phthalic acid, isophthalic acid or benzoic acid, is purified by heating with water to 230-280 DEG  C. and cooling the resultant solution to a temperature not below that at which the impurities start to separate out and separating the terephthalic acid which crystallizes out.  The impurities may be isolated by further cooling of the residual aqueous solution.  In a modification, the purification is conducted continuously by feeding the heated solution of crude terephthalic acid to a crystallizing zone where the crystals of terephthalic acid are allowed to settle while the mother-liquor passes on.  In a further modification, the settled crystals may be passed into a vertical tube where they fall by gravity against a slow stream of clean water at the crystallizing temperature, the clean crystals being withdrawn from the bottom of the tube.  Examples are given.

Title: Improvements relating to shuttleless looms
IPC: D03D47/44
Filed: 1946-02-26
Abstract: 611,926. Shuttleless looms; forming selvedges. ROBINSON, P. W. Feb. 26, 1946, No. 5961. [Classes 142(ii) and 142(iv)] A fabric in which the weft is inserted in loops has a selvedge formed by looping a selvedged thread 76 through each successive weft loop 57 and through the preceding selvedge thread loop 79. A gap 70 in the weft insertirig needle 67 enables a hook 71 to take the weft loop 57 forward and hold it against a plate 44. A needle 59 (actuated by a crank 61 and a crosshead 63) carries the selvedge thread 76 through the weft loop 57, through a hole in the plate 44, and through the preceding selvedge thread loop 79, which is meanwhile held by a hook 43; the hook 43 is then moved upwardly and towards the fabric (by a face cam 39 and a grooved cam 33) so as to release the loop 79; on its return movement, the hook engages the thread 76, whereupon the needle 59 recedes, leaving a fresh loop 79a on the hook, as shown in Fig. 2. The hook 71 is actuated by a grooved cam and is given a dwell as soon as it clears the gap 70, its forward movement being completed after the weft inserter 67 has been withdrawn from the shed. Another grooved cam actuates the cam shafts 19, 20 through a lever 27. In the form described in the Provisional Specification, a hook 71 is not used, the needle 59 engaging the weft loop directly by passing through the gap 70. It is also stated that the needle 59 may move in an arcuate path, and that if more than one weft inserter is used, a selvedge mechanism is provided for each.

Title: Milk product containing an antibiotic
IPC: A23C9/158
Filed: 1950-03-09
Abstract: A milk product comprises untreated or pasteurized milk and, uniformly distributed in solution throughout the milk, an antibiotic which cannot be absorbed by the intestinal tract nor be decomposed by digestive secretions, and which co-operates with the milk to change a predominantly gram-negative intestinal flora to a lactobacillus or predominantly gram-positive flora without adversely affecting the nutritive value or stability of the milk. Suitable antibiotics are streptomycin and dihydrostreptomycin, and the preferred concentration is 1-3 mg. of antibiotic/100 g. The disinfecting and preserving effect on stored milk to which streptomycin or dihydrostreptomycin has been added is more pronounced at 10-20 DEG  C. than in an ice box.  A product formed by dissolving 25 mg. of streptomycin in 1 litre of mother's milk kills bacteria which cause inflammation of the bowels and indigestion in sucklings.
