Title: Improvements in and relating to mooring towers and mooring devices for airship stations
IPC: B64F1/14
Filed: 1928-06-20
Abstract: 311,966. Krell, O. June 20, 1928. Anchoring.-A mooring tower for airships mounted on, and above the entrance to, a rotatable hangar, is of stream-line section or of latticework enclosed in a stream-lined casing, the airship being attached by a universally movable connection to a crab which travels up and down the tower. The crab, during descent, moves on to a vertical track which forms an extension of the track on the tower and is mounted on a carriage on which the airship is run into the hangar. The tower, shown in section in Fig. 1, isprovided with vertical runways 26, 26<1>, Fig. 2, for the crab 3, portions 8, 8<1> of the tower being adapted to be swung outwardly on hinges 6, 6<1>, or slidden along the sides of the tower, to give a free passage to the nose S of the airship. Each portion 8, 8<1> extends over the complete height of the tower and may be subdivided into a number of independently opening sections. The crab 3 carries curved rails 4, 4<1> engaging rollers 7, 7' on the portions 8, 8' so that when it is moved vertically by racks 21 and pinions 22 driven by worm gearing 23, the portions 8, 8<1> are automatically swung open against the action of springs. Electric motors energized by a battery carried on the crab may supply the driving power. If the portions 8, 8<1> are not subdivided they are closed by an attendant after the airship has passed. The nose of the airship carries a member 5 having external screw-threaded portions 5<1>, Fig. 5, and cut away portions alternately around its circumference so that it may be inserted in a nut 15 having corresponding internal threaded and cut away portions 15<1>, the screw and nut being then slightly rotated to lock them together. The nut is mounted within the inner ring 19<1> of a cardan joint 19, 19<1> carried by the crab, springs 20, 20<1> being provided normally to hold the ring 19 in a vertical plane. In order to guide the screw 5 into the nut 15, the screw is furnished with fins 16 adapted to engage slots in a funnel 14 rotatably mounted in the ring 19<1> and connected to the nut 15 by worm gearing 17 by which the screw and nut are relatively rotated. The mooring cable 10 is connected to the airship bv a screw device 11, 11<1>, 12 similar to the device 5, 15, 17 and the cable carries a coned member 13<1> which also assists in guiding of the screw 5 into the nut 15. The cable is detached from the airship before it is run down on the crab.

Title: Manufacture of compounds having an affinity for cotton
IPC: D06P3/68
Filed: 1929-01-15
Abstract: 323,710. Imray, O. Y., (I. G. Farbenindustrie Akt.-Ges.). Jan. 15, 1929. Divided on and addition to 313,636. Aminobenzoylamino compounds.- Substances having an affinity for cotton are made by subjecting to a slight reduction, such as is required to convert an aromatic nitro-compound into an azo- or azoxy-compound, the sulphonic acid of an aromatic nitro-amino-compound nitrobenzoylated in the amino-group, the resulting nitro product being converted into the corresponding aminocompound either during or after the slight reduction. The products may be diazotized on the fibre and developed with component to form dyestuffs. In examples, (1) 4-nitro-1- (4<1>-nitrobenzoylamino)-benzene-2-sulphonic acid (obtained by nitrating the condensation product from aniline- 2-sulphonic acid and 4-nitrobenzoyl chloride) is reduced with sodium sulphide; it is adsorbed by cotton yielding a bright yellow and gives a reddish yellow when diazotized and coupled with 1- phenyl-3-methyl-5-pyrazolone, (2) 1-(4<1>-nitrobenzoylamino)-4-nitronaphthalene-6-sulphonic acid (obtained by nitrating the condensation product from 1-naphthylamine-6-sulphonic acid and 4- nitrobenzoylchloride) is reduced with sodium sulphide; a yellow brown is obtained by diazotizing on cotton and developing with 1-phenyl-3-methyl- 5-pyrazolone. Glucose may be used as reducing agent.

Title: Process for the production of paper and rubber and similar combinations
IPC: D21H17/35
Filed: 1930-06-11
Abstract: 356,310. Paper formed from pulp combined with rubber latex &c. JACKSON, L. MELLERSH-, 28, Southampton Buildings, London.-(General Rubber Co. ; 1790, Broadway, New York, U.S.A.) June 11, 1930, No. 17970. [Class 96.] In the manufacture of rubber latex paper by incorporating rubber latex with the pulp in the beater, the rubber is deposited in finer particles and a more stable pulp mix is obtained by the addition of a protective colloid such as acetylated starch (known under the trade name feculoid or feculose), glue, or casein, to the partially beaten pulp, in the proportion of 1-5 per cent of the fibrous material present. The mixture is then made alkaline to litmus with ammonium hydroxide, caustic soda, sodium silicate, or other alkali and the beating operation completed. The beater roll is then raised frcm the bedplate and a rubber dispersion containng 10-20 per cent dry rubber is added, preferally just in front of beater roll and the dispersion and paper pulp thoroughly mixed. About two-thirds of the required amount of coagulating sclution, such as paper-makers' alum, zinc sulphate, or similar chemical is next added and the mixing continued for a short period. During this operation the rubber is deposited on the fibres in very fine particles. The remainder of the coagulating solution, sufficient to impart a strongly acid reaction to the mixture, is then added. The coagulating solution may be added slowly to the mass in one continuous operation. Where glue is used as a protective colloid, a stronger paper is obtained if the glue is coagulated with protein precipitants such as heavy metal salts, organic colour bases, alkaloid reagents, polyhydric phenols such as tannic acid, and the various tannic extracts. By the use of the protective colloids with paper pulp, ordinary commercial rosin size may be added to the beater at any desired stage without the premature coagulation of the rubber and the resultant formation of rubber spots on the finished paper.

Title: Improvements in cutting out trousers, slacks and shorts
IPC: A41D1/06
Filed: 1953-06-22
Abstract: 776,537. Cutting out wearing-apparel. RODGERS, S. M. June 22, 1954 [June 22, 1953], No. 18001/54. Divided out of 773,577. Class 141. Drafting patterns for cutting out slacks, shorts or trousers are characterized in that when the pattern for each leg lies flat as shown in Fig. 6 the fly seam and the crotch seam are made substantially parallel to each other to the point where the seams begin to converge towards the horizontal at their intersection with the crotch seam o, to form a symmetrical U-shaped gap with the distance between the parallel portions of the fly and seat seams equal to the front to back dimension of the body at the seat line. Allowance for bending is normally provided by introducing a seat angle, the gap between fly and seat seam being V-shaped. This allowance is made according to the invention by increasing the width of the U-shaped gap, the extra material then being under the crotch instead of in the seat. This allows the trousers to hang without bagging below the seat. To provide the necessary walking clearance between the trouser leg and the wearer's knee the pattern is split at the front and back crease position as shown in Fig. 3 and an angle h introduced in the front and an angle k in the rear of the trouser leg. In both illustrations the pattern is shown having the horizontal datum fork line q aligned on the several pattern parts.
