Filed: 1929-02-07
Abstract: 305,592. I. G. Farbenindustrie Akt.- Ges. Feb. 7, 1928. [Convention date]. Indigo dyes are produced from 1-amino-3: 6- dimethyl-4-halogenbenzene or 1-amino-2-carboxy- 3 : 6-dimethyl - 4 - halogenbenzene by known methods for converting aromatic amino compounds, e.g. by caustic alkali fusion of the sodium amide of the corresponding phenylglycine or by condensation of the corresponding phenylglycine o-carboxylic acid, e.g. by means of acetic anhydride. In a. modification, 1-amino-3: 6- dimethylbenzene and 1-amino-2-carboxy-3 : 6- dimethylbenzene are used as starting materials, and the corresponding indigo which is then produced subsequently treated with halogen or a substance yielding halogen to introduce two atoms of the latter. The dyestuffs mav also be obtained by reduction of the corresponding isatin a-derivatives. According to examples : (1) 4 : 7- dimethyl-5-bromisatin or 4: 7-dimethyl-5-chlorisatin is treated with phosphorus pentachloride in chlorbenzene, and the resulting a-chloride reduced by means of sulphuretted hydrogen; (2) 4: 7: 4<1>: 7<1>-tetramethylindigo (obtained from 1- amino-2: 5-dimethylbenzene) is brominated in nitrobenzene so as to give 4 : 7 : 4<1> : 7<1>-tetramethyl-5: 5<1>-dibromindigo. 4: 7-Dimethyl-5-brom- (or chlor) isatin is prepared from 1-amino-3 : 6-dimethyl-4-brom- (or chlor) benzene by means of the Sandmeyer reaction, (Specification 128,122). The Specification as open to inspection under Sect. 91 (3) (a) refers also to the phenylaminomalonic-ester method of converting the amine into the corresponding indigo.

Title: Improvements relating to the manufacture of water-softening materials
IPC: C01B33/46
Filed: 1923-02-14
Abstract: Zeolitic water-softening substances, whether prepared by the precipitation or fusion processes, are hydrated slowly so as not to break up the lumps, by means of a current of air and steam, the treatment occupying several hours, and are then broken up into pieces of the desired size.  The proportion of steam used is small at first and increased later.  When the material is prepared by precipitation it may be dried more completely than usual, for instance by heating to 80-100 DEG  C. until its weight is constant before hydration, which is effected only after the dried precipitate has cooled. Specification 108,773 is referred to.

Filed: 1942-04-10
Abstract: 556,592. Wireless loop aerials. STANDARD TELEPHONES & CABLES, Ltd. April 10, 1942, No. 4746. Convention date, April 12, 1941. [Class 40 (v)] A loop antenna system for short wave operation comprises at least three elongated conductors 20, 21, 22, Fig. 2, each less than a quarter wavelength long, arranged to form a substantially closed periphery having a single plane of symmetry, together with a transmission line 28 connected to at least one of the conductors at the plane of symmetry, and means for controlling the energy distribution to produce a single current loop in each of the conductors. As shown in Fig. 2, the member 20 is coupled to the members 21, 22 by capacities 24, 25 which, when the antenna is made of flat strips, may be formed by overlapping them. By decreasing the capacities, a field pattern elongated in the plane by symmetry of the loop is obtained; further, a relatively low voltage occurs at the junction point of the transmission line 28 avoiding the effects of sleet formations at high voltage points when the loop is mounted in the normal manner on an aircraft. In a modification, the transmission line is connected at the opposite point of the loop, two conductors thus replacing the conductor 20, and the adjacent ends of the conductors 21, 22 are coupled by a variable capacity. Fig. 6 shows another form comprising four conductors 60-63 in which the conductors 62, 63 are overlapped to form a capacity coupling, and are connected by a transposed tie-line 65 to the conductors 60, 61. In a modification of this form, the tieline 65 is replaced by two transmission line sections each formed by extending the members of one pair of conductors 60, 62 and 61, 63 inwardly from their adjacent ends in substantially parallel overlapping relation. Fig. 8 shows a further modification, in which transmission line sections 70, 71 are formed by peripheral overlapping extensions of the conductors 60, 62 and 61, 63.
