Title: Process for converting high boiling point hydrocarbon oils into low boiling point oils
IPC: C10G11/08
Filed: 1921-08-22
Abstract: 189,200. Marks, E. C. R., (Hoover Co.). Aug. 22, 1921. Hydrocarbons, cracking.-In converting high-boiling hydrocarbon oils into lower-boiling oils by the action of aluminium chloride or similar catalyst, the heated mixture of oil and catalyst is circulated over heated surfaces, and a part of the mixture is withdrawn from the circuit, and treated to separate the aluminium chloride which is returned to the circuit. The mixture of oil and catalyst in a chamber 7 passes downwards through tubes 12 heated by fluegases or by hot oil from a still 1 circulating in the outer casing, and is withdrawn, either from the base 9 by a pipe 21 or at a higher point by pipe 19, and is returned to the upper part of the chamber by pumps 22, 18. Fresh heated oil is added through a pipe 5 by a pump 6 from the still 1, and part of the oil is sprayed through a nozzle 24 into the vapours in a hood 23 to separate vapours of aluminium chloride. The vapours rise through a baffle chamber 25 to a reflux condenser 27 from which the heavy fractions are returned by pipe 30 to the chamber 7. The remaining vapours pass to a final condenser 28 and gas holder 37. The heavy sludge which settles in the base 9 of the chamber 7 is withdrawn at intervals through a cock 31<a> and pipe 31, and is mixed with hot gases which may be the gas formed during the process and collected in the holder 37, or may be chlorine or hvdrochloric acid gas admitted by pipe 38, and heated by passage through a coil 35<a>. The sludge is sprayed through a nozzle 33 into the chamber 32 heated to about 400‹ F. The vapours of aluminium chloride and hydrocarbons pass into a chamber 43, and are washed by a shower of oil from a nozzle 44.. The oil mixture from the chamber 43 is added to the mixture in the chamber 7 by a pump 46. The light vapours pass by a pipe 47a to the reflux condenser 27. A chamber 39 attached to the chamber 32 may contain metallic aluminium through which chlorine or hydrochioric acid gas may be passed to form fresh aluminium chloride. In a modification, the whole of the mixture of oil and catalyst withdrawn from the chamber 7 by pumps 18, 22, is passed through heated chambers 32, and the vapours from these chambers are passed directly into the chamber 7.

Drawings to Specification. Heading H4P. In a two-way telegraph system, including error correction by repetition, successive blocks of signals are differently designated by notional alternate markings I and II. At each end of the system there are two toggle counters which determine whether a block is to be repeated or printed. If a block is received correctly and if the two receiver counters agree, it is printed. If they do not, a repetition requesting signal is sent and the block is repeated. In one embodiment a first one of the two counters steps at the end of each operating cycle and the second steps whenever a block is correctly received and printed. In a second embodiment the first counter does not step at the end of a cycle during which an odd-numbered reception of an error has occurred. A block from the other station must be received before a second block can be transmitted; the gap between the blocks may be filled with blocks from other channels.

Title: Multistage transistor pulse amplifier
IPC: H03K5/02
Filed: 1961-06-22
Abstract: 910,727. Transistor pulse circuits. SPERRY RAND CORPORATION. June 22, 1961 [Nov. 16, 1960], No. 22698/61. Class 40 (6). A pulse amplifier comprises a normally conductive first transistor 10 having its collector connected to its supply through an inductive load 20 and through a resistor to a second normally non-conductive transistor 12 having a load in its collector circuit. A positive pulse applied to terminal 44 will cut off the first transistor so that the inductor current will be diverted to the second transistor. This causes it to become highly conductive with a wide bandwidth but low gain so that the initial current builds up in the load quickly. The inductor current and thus the second base current decays to a lower value at which the transistor gain is higher but the bandwidth is lower. A capacitor 54 speeds the switching off of transistor 12 when the pulse input at 44 terminates. An output transformer 58 feeds a magnetic core storage line 68 through an R.C. network 81 dimensioned to make the output circuit appear resistive.

Abstract: 1,141,118. Block copolymers. TOYO RAYON K.K. 16 May, 1967 [18 May, 1966; 24 May, 1966], No. 22734/67. Heading C3R. Block copolymers of polyamide and polyester are prepared by heating a solid mixture of polyamide and polyester at a temperature above the second order transition point of the polymer component having the highest second order transition but below the m.p. of the polymer having the lowest m.p. The solid phase reaction may take place at reduced pressure or at atmospheric pressure in an inert gas stream. An intimate mixture of polyamide and polyester is desirable and may be obtained by melt blending the polymers prior to reaction or by dissolving in a solvent and then either distilling off the latter or pouring the resultant solution into a non-solvent liquid. The solid mixture used in the reaction may be a powder or be in the form of chips, pellets or flakes. The polyamide may have M.W. 1000-30,000 and the polyester M.W. 2000-30,000. Although the resultant block copolymers are fibre forming the constituent polyamide and polyester need not be fibre forming. At least 50% of the polyamide terminal groups may be amino or carboxyl and at least 50% of the polyester terminal groups may be hydroxyl. Suitable polyamides are polycapramide, polyhexamethylene adipamide. A suitable polyester is polyethylene terephthalate. Mixing may be achieved by melt blending at 260-320 C. for up to 20 minutes; reaction may take place between 150 C. and the m.p. of the component having the lowest m.p. Fibres may be obtained by melt spinning. Composite fibres may be obtained by melt-spinning a block copolymer prepared by the process according to the invention with another fibre-forming polymer.
