Patent GB-1462254-A (GB)
Title: Alkylation of aromatic amines
IPC: C07C211/47
Filed: 1974-05-24
Abstract: Aromatic amines which are substituted on the ring by one or more optionally substituted aliphatic or cycloaliphatic hydrocarbon radicals are prepared by reacting an aromatic amine having at least one unsubstituted ortho-position on the ring and at least one hydrogen atom bonded to the amine nitrogen atom with one or more aliphatic or cycloaliphatic hydrocarbons which contain at least one olefinic double bond and which may contain substituents which do not affect the reaction. This reaction is carried out at a temperature from 200 to 500 DEG C in the presence of a catalyst formed by reaction of aluminium or an alkylaluminium compound with an aromatic amine. The essential feature of the process is that hydrogen halide is added to the reaction mixture in such amounts that up to two halogen atoms are obtained per aluminium atom in the mixture. The amines prepared are valuable intermediates for the preparation of dyes, and are used for the synthesis of various selective herbicides.

Title: Improvements in or relating to integrating devices
IPC: G01F15/07
Filed: 1944-11-27
Abstract: 590,194. Integrating mechanism. ELECTROFLO METERS CO., Ltd., and FRENCH, J. W. E. Nov. 27, 1944, No. 23591. [Class 106 (iv)] An integrating means or device comprises an elongated element or rod, means for continuously imparting longitudinal reciprocating movements to said elongated element or rod, means for dividing each movement in one direction into two components and means whereby one of the components of each of a series of successive movements may be summated or passed on to a suitable form of summating or counting device. In the embodiment shown, Figs. 1 and 2, a rod 1 is reciprocated in guides 1a by a clock, electric motor or other constant-speed source of power. The guides 1a are fixed in a framework 10 mounted for angular movement about an axis 11 parallel with the rod 1. As the rod moves from right to left, Fig. 1, a stylus 5 thereon rides on a horizontal cam 6, the position of which is determined by the element whose displacements are required to be integrated. When the stylus 5 reaches the end of the cam 6, the rod 1 is biassed to fall so that its end rests on a roller 9 whereupon further movement of the rod to the left will cause the roller 9 which is interconnected with a counter to drive said counter a corresponding amount. When the rod 1 reaches the end of its stroke to the left, a tappet 4 thereon rides on an abutment 2 and the rod is raised against a stop 8. As the rod 1 reaches the end of its following stroke to the right, the tappet 4 rides on an abutment 3 and the rod is forced down until the stylus 5 rests on the cam 6, whereupon the cycle of operations begins again.

Abstract: 261,509. Coventry Automatic Telephones, Ltd., and Collyer, J .E. Sept. 22, 1925. Automatic exchange systems.-In a system employing register-controllers, district offices are not provided with register-controllers, but make use of those at the main exchange. A calling line at a district office becomes connected to a repeater embodying a line switch A which selects a trunk to the main exchange, and a rotary discriminating switch B which responds to the first three dialled digits. If these correspond to the designation of the district office, the trunk is released, and the switch B immediately continues its motion in search of an idle local selector. Specification 170,308 is referred to. Circuit arrangements. Line relay 1 and release relay 2 energize and connect up the magnet 22 and switching relay 6 of the switch A. When an idle trunk is found, the line relay at the incoming selector energizes over polarized relay 5, and a register-controller is taken into use. Dialled impulses are repeated over the trunk at contact 49 and to the magnet 33 of the switch B at contact 30, sluggish relay 3 being energized during each train in the usual manner. Assuming the name of the district office is West, and that the call is a local one, the switch B takes 9, 3 and 7 steps in succession, and relays 11, 8, 10 energize over wiper 35 after the successive relapses of relay 3. Relay 10 disconnects switching relay 6, and the trunk is released. and at contact 41 a self-interrupting circuit is closed for the magnet 33, which rotates the switch B over the whole of its bank in search of an idle local selector. Switching relay 7 energizes when this is found, and the call is completed in the usual manner. If no idle selector is found, relay 9 energizes in the position preceding that in which hunting commenced and cuts the drive, and busy tone is applied to the a-wire. Upon release, the switches A, B are restored to normal. If the call is not a local one, as soon as the digits received by the switch B indicate this, relay 9 energizes over wiper 35, locks independently of relay 3 and cuts the drive. Contacts 59, 60 ensure the operation of relay 9 if the switch is dialled round to its normal position.
