Abstract: 1,162,557. Dibromoalkanes. EL PASO PRODUCTS CO. 14 Oct., 1966, No. 46094/66. Heading C2C. Dibromoalkanes are obtained by introducing anhydrous diolefin and a molar excess of anhydrous hydrogen bromide into a reactor maintained under an anhydrous atmosphere at from - 20‹ to 40‹ C. in the absence of moisture and in the presence of a free-radical initiator. It is preferred to utilize terminal or alpha, omega-diolefins such as 1,3-butadiene, 1,4- pentadiene, 1,5 - hexadiene or 1,6 - heptadiene and the example specifies the hydrobromination of 1,5-hexadiene wherein 1,6-dibromohexane is the main product while 2,5-, 1,4- and 1,5-dibromohexane and 5- and 6-bromohexene-1 are all formed in minor amounts. However any diolefin may be used in the hydrobromination. The free-radical initiator is usually oxygen.

Abstract: 996,726. Detecting burner flames. ELECTRONICS CORPORATION OF AMERICA. Dec. 12, 1963 [Dec. 18, 1962], No. 49164/63. Heading F4T. [Also in Divisions G1 and H3] A condenser 18, Fig. 1, is charged from an AC source by the rectifying action of a photocell 26 sensing a gas burner flame 12 or by an electrode 14 disposed in the flame and the condenser is partially discharged by a neon-filled glow discharge tube 30 to provide a signal which is applied to a transistor 40 in an amplifier adapted to energize a relay 54 having contacts controlling an indicator circuit. The primary winding of a stepdown transformer 34 is connected into the condenser discharge circuit and a further condenser 36 is connected across the primary winding to form therewith a damped oscillatory circuit so that a series of pulses are derived from the original discharge pulse. The transistor 40 is an NPN transistor connected in common emitter configuration. The amplifier also includes a PNP transistor 42 connected in emitter follower configuration and a PNP transistor 44 which produces an inverted pulse in the relay 54. A condenser 56 across the relay produces a slow release operation. In an alternative arrangement, Fig. 2, a condenser 88 is charged by the rectifying action of the flame electrode 60 or a photo-cell 66. When the neon tube 90 breaks down a normally conductive transistor 94 in a monostable vibrator comprising the transistor 94 and a second transistor 100 is rendered non- conducting and remains so until a condenser 112 has discharged. Initially the base electrode 122 of a third transistor 120 is positive so that the transistor is non-conducting but immediately after the vibrator is triggered the voltage on the base 122 becomes negative and the flame relay 130 is therefore energized. A condenser 110 extends the period at which the base is negative. A resistance 84 and a condenser 82 allow rapid charging of the distributed capacitance between the flame electrode leads and ground. Silicon controlled rectifiers or switches may be utilized to respond to the flame indicating signal.
