The products are fire resistant or retardant.ALSO:Compounds of the formula <FORM:1079223/C2/1> where each X is hydrogen or halogen, at least two being halogen, and R is hydrogen or an alkyl, cycloalkyl, aryl, aminoalkyl, polyaminoalkyl, aminoalkyleneaminoalkyl, polyaminopolyalkyleneaminoalkyl, aminoaryl, polyaminoaryl, aminoaryleneaminoaryl, polyaminopolyaryleneaminoaryl, aminocycloalkyl, polyaminocycloalkyl, or aminocycloalkyleneaminocycloalkyl radical, are prepared by reacting a polyhalopolyhydromethano - 2,3 - naphthalenedicarboxylic acid or anhydride with RNH2, e.g. at 50-250 DEG  C.  Solvents such as aromatic hydrocarbons, aliphatic hydrocarbons or cyclic paraffins may be used.  The products are used for curing epoxy resins and for shrink-proofing fibrous materials.ALSO:Shrink-proofing properties are imparted to fibrous materials p  such as wool by an interfacial polymerisation process in which the material is treated with a compound of formula:-  <FORM:1079223/D1-D2/1> where each X is hydrogen or halogen, at least two being halogen, and R is hydrogen or an alkyl, cyclo alkyl, aryl, aminoalkyl, polyaminoalkyl, aminoalkylene aminoalkyl, polyaminopolyalkyleneaminoalkyl, aminoaryl, polyaminoaryl, aminoaryleneaminoaryl, polyaminopolyaryleneaminoaryl, aminocycloalkyl, polyaminocycloalkyl, or aminocycloalkyleneaminocycloalkyl radical, and then with a polyacid polyhalide, both the imide and the polyacid polyhalide being in solutions which are mutually immiscible.  The fibrous material so treated has shrink-proofing properties as well as smoothness after drying, excellent hand, increased break strength and tear strength and improved resistance to abrasion, chemicals and filling, and also anti-bacterial, antifungal and insecticidal properties.

Abstract: 1,037,260. Electric selective signalling; data retrieved. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 14, 1964 [Dec. 30, 1963], No. 50724/64. Headings G4H and G4T. In a data retrieval and display system interlock circuitry permits a single remote station to request data from a central store and display the information at the requesting station only. To activate a sub-station 17 (Fig. 2, not shown) a switch 79<1> is closed and relay 50<1> activated which removes the relay drive from upper and lower sub-stations 17<1> and operates a relay 30 to remove the relay drive from all other terminals 11, 13 &c. and operate a busy light 88. Line 26 is joined to line 20 to represent a request data signal to the central processing unit 1 and when the CPU 1 is ready a signal is sent on line 22 which lights an entry light 86 and sends a signal on line 23 to the associated keyboard coils. The interlock circuit is reset by a signal on line 21 which releases relays 30, 40, 50, 60. Requests from the keyboard 8 (Fig. 3, not shown) are entered into a buffer 100 and stored until the entire request is entered and then transferred to the CPU 1. When ready to answer, a clock 102 is started and a character fed via a six bit storage 110 and decode matrix 114 to a core matrix 108 where it is scanned by column and line counters 104, 106 receiving clock pulses 102. The character signals are serially applied to a sense amplifier 119 connected to an unblank terminator 151. The counter 106 is connected to character and line counters 126, 134 which operate character and line analogue converters 130, 134 to produce currents applied to adders 144, 148 receiving currents from a horizontal character scan ramp 138 and vertical character scan step 148 to operate horizontal and vertical drivers 152, 160 for the dark scan cathode-ray tube 6. The interlock circuitry 5 energizes that voltage regulator 168 associated with the requesting keyboard to operate that CRT only. The keyboards 8 are connected to the buffer store 100 in order that the keyed data may be displayed.

Abstract: 1,144,415. Producing nuclear reactions. SANDERS NUCLEAR CORP. 9 Nov., 1967 [2 Dec., 1966], No. 51129/67. Heading G6P. The radio-active isotopes thallium 170 and thallium 171 are formed by neutron irradiation in a nuclear reactor. The initial target is a stable organic compounds of thallium 169 with a carrier compound, which, in the reactor, forms thallium 170 in the compound. The reaction employed is 169 Tm (n,γ) 170 Tm. The emitted gamma ray provides recoil energy sufficient to break the chemical bond between the thallium 170 and the carrier. The process is repeated, upon the combination of the free thallium 170 with a second stable carrier, to form thallium 171 which, when freed by neutron recoil, is separated from the target material. Carrier compounds are formed of materials having low neutron absorption cross sections and are organic compounds comprising hydrogen, oxygen, nitrogen and carbon, for example, hydroxyquinoline chelate.
