Title: Char composition and a method for making a char composition
IPC: C09C1/48
Filed: 1976-05-14
Abstract: 1494300 Destructive distillation of rubber OIL SHALE CORP 14 May 1976 [16 May 1975 14 Aug 1975] 20055/76 Heading C5E A method of producing a char from a rubber composition containing polymeric hydrocarbons and carbon black, e.g. scrap tyres, comprises simultaneously pyrolysing and grinding the composition in the absence of oxygen by contacting the composition with heat-carrying solids for a sufficient length of time to volatilize and depolymerize the polymeric hydrocarbons and thus produce a solid char and hydrocarbon vapours. The shredded rubber is dried at 225-250‹ F. and then fed into a rotating retort with the heat-carrying solids, which are prefereably at a temperature of 1100-1500‹ F., giving a pyrolysis temperature of 950-1000‹ F. The rotational speed of the retort must be sufficiently high to ensure adequate heat transfer between the rubber and the heat-carrying solids, and to effect grinding. The solids may be metallic or ceramic balls (e.g. alumina) and are heated in a conventional ball heater utilizing flue gas.

Title: Reversible Electrical Code Converter
Inventor: ABE TADAO
IPC: H03M7/00
Filed: 1967-05-01
Abstract: 1,150,675. Reversible code converters. NIPPON ELECTRIC CO. Ltd. 1 May, 1967 [4 May, 1966], No. 20058/67. Heading G4H. A reversible electrical code converter comprises a conversion matrix and a gating arrangement having two states, the gating arrangement being such that in one state it primes AND gates G1-G4 (Fig. 1) to enable coded signals in a first code X to be converted into a second code Y<SP>1</SP> and in its second state it enables AND gates G5-G8 to enable coded signals in the second code to be converted back to the first code. A two-bit coded signal (0, 1) in the first code X fed to bi-stable devices F1, F2 results in a four-bit output signal from the bi-stable devices which is fed through the gates G1-G4 primed by the output of bi-stable device F3 and amplifier inverters A1-A4 having output signals 0, 1, 1, 0 respectively to the diode conversion matrix to give an output signal only on line 7. This results in diodes D11, D16 conducting to give output signals on lines 9, 11. These lines are not however connected to OR gates G11, G12 so zero signals are applied to inverter amplifiers A11 A12 to give an output code (1, 1) on the terminals 29, 30. In a similar manner if the code (1, 1) is applied to the input terminals 25, 26 the original signal (1, 0) is obtained at the terminals 27, 28.
