Abstract: 298,584. Johnson, J. Y.. (I. G. Farbenindustrie Akt.-Ges.). June 9, 1927, Hydrocarbons; caoutchouc, synthetic. - The products of the destructive hydrogenation of carbonaceous materials are polymerized, if necessary after a preliminary treatment to increase their content of unsaturated compounds, so as to produce hydrocarbons of high molecular weight and in particular rubber-like substances. The preliminary treatment may comprise dehydrogenation, cracking, or thermal or electric treatment; it may be effected with or without the aid of catalysts. Halogens may be introduced into the hydrocarbon molecule and halogen acids subsequently split off. The unsaturated compounds may be isolated from the mixture before being polymerized. The following examples are given : (1) A product of the destructive hydrogenation of oil is treated with sulphurous acid, the solid products which settle are heated or treated with alkalies, yielding substances which can be polymerized into caoutchouc-like products, e.g. by treating with metallic sodium; (2) a product of hydrogenation of coal is dehydrogenated by passage over chromium oxide at 500‹ C., and the product is treated with hydrochloric acid and distilled, yielding amyl chloride, which is converted into trimethyl-ethylene by treatment with barium chloride at 400‹ C.; the product is treated with chlorine in vacuo yielding chloramylene, and hydrochloric acid is split off with production of isoprene, which is then polymerized with stannic chloride; (3) a coal hydrogenation product is cracked at red heat in presence of quartz or platinum, yielding butadiene, which is polymerized by treatment with sodium.

Headings H3R and H4L. [Also in Division G1] A transmission device to be carried by a missile or aircraft comprises a housing containing a radio transmitter, a sensing head connected by a normally coiled cable to the input of the transmitter, an aerial in compact form connected to the output of the transmitter, and a parachute connected to the aerial, releasing means being provided to permit the sensing head to fall as far as allowed by the uncoiled cable and to permit the opening of the parachute and consequent erection of the aerial. The device enables data concerning conditions at or near ground level to be obtained in inaccessible or hazardous areas. If used to detect gamma radiation the detector may be a cadmium sulphide cell and to reduce its response time it includes a built-in beta source of about 1 roentgen/hour, the change in cell resistance due to this source being backed off later in the system. The change in cell resistance due to gamma radiation controls the frequency of a pulse generator and these pulses modulate the signal from a crystal oscillator. At the receiver a count of received pulses is made over a timed period and the count may be displayed on cold cathode counter tubes or the like. The detector is supplied with 100 volts D.C. from a known transistor voltage converter. General arrangement, Fig. 1 (not shown).- The apparatus is contained in a mortar bomb, the parachute 1 being contained within the nose cone and attached to the coiled aerial 2. Batteries 3 are carried in a central tube 4 and the radiation detector is in the rear of the tube, this end of the tube carrying a tapered spool carrying a coil 5 which connects the detector to the bomb. Strip boards 6 carry the electronic components. The bomb casing falls free over the area in question, allowing the parachute to open, switching on the power supply and releasing the detector. Pulse modulation.-Transistors VT3, VT4 of a multivibrator, Fig. 3, are provided with transistors VT1, VT2, respectively, in their emitter circuits with A.C. coupling between their emitters provided by a capacitor 20. The signal from the radiation detector is supplied to the bases of transistors VT1, VT2 and the consequent variation in resistance provides a corresponding variation in the pulse repetition frequency from the multivibrator. Keying a carrier wave.-The transmitter, Fig. 4, includes a crystal controlled oscillator VT5, driver stage VT6 and power amplifier stage VT7, VT8. The modulated pulse signal is supplied to the base of transistor VT9 to modulate the D.C. conditions of transistors VT6, VT7, VT8 so that there is zero current in these stages between pulses.
