Patent GB-863423-A (GB)
Title: Method of producing bis-(carboxyphenyl)-alkanes
IPC: C07C51/265
Filed: 1959-03-19
Abstract: Bis-(carboxyphenyl)-alkanes of the general formula:  <FORM:0863423/IV (b)/1> in which R and R1 are alkyl groups containing from 1 to 4 carbon atoms and n is 1 or 2, are produced by the liquid-phase oxidation of ditolylalkanes of the formula:  <FORM:0863423/IV (b)/2> the oxidation being achieved by passing an oxygen-containing gas through a mixture of the ditolylalkane, an oxidation-catalyst (e.g. cobalt naphthenate), and a tertiary monoalkyl-benzene such as t-butylbenzene, t-amylbenzene, or t-hexylbenzene.  In an example, oxygen is passed for 22 hours through a mixture of 2,2-bis-(4-tolyl)-butane (155 parts), t-butylbenzene (87 parts) and cobalt naphthenate, maintained at a temperature of 135 DEG C.  The reaction-mixture is then cooled to 60 DEG C., when crude 2,2-bis-(4-carboxyphenyl)-butane crystallizes out.  The mixture is filtered, and the crystals are washed with t-butylbenzene, followed by benzene.  The crystals are extracted with aqueous sodium carbonate solution; and the extract is acidified to reprecipitate the acid. The acid is taken up in ether, the solution is dried, and the ether is then evaporated.  The product is finally recrystallized from glacial acetic acid.  The octoates, oleates, linoleates, naphthenates and stearates of cobalt, manganese and lead are specified as suitable oxidation-catalysts.  The ditolylalkanes, required for the process, are preferably obtained by condensing a hydrocarbon having the formula:  <FORM:0863423/IV (b)/3> wherein R11 is a hydrogen atom or alkyl radical and n is 1 or 2, with ethylene, n-propylene, isopropylene, one of the butylenes, or mixtures containing one or more of these hydrocarbons.  For example, 2,2-di(p-tolyl) butane is produced by reacting 1,1- di(p-tolyl) ethane with ethylene, the reaction being carried out under pressure, at a temperature of 170 DEG C., and in the presence of sodium and o-toluic acid.  The ditolylalkanes may also be produced by reacting hydrocarbons of the above formula with alkyl halides, or by dimerizing cymene or other alkyltoluenes.  A list of ditolylalkanes, which may be prepared, is given; this list includes 1,2- di (p-tolyl)-1, 1, 2, 2-tetramethyl-ethane; 1, 2-diethyl-1, 2-dimethyl- 1, 2-di(p-tolyl) ethane; 3, 3-di(o-tolyl) pentane; and 5, 5-di(m-tolyl) nonane. Specification 822,188 is referred to.

Abstract: 1,118,823. Card indexes. BRITISH RAILWAYS BOARD. 4 March, 1966 [9 March, 1965], No. 9950/65. Heading B6E. In a card indexing system wherein the cards 8 are arranged in a staggered pack so that one edge portion projects beyond the corresponding edge portion of the card next above, each card is pivotally supported at its upper edge on a wire or rod 7 having cranked ends which engage parallel side rods 2 of a parallelogram frame 1 formed of the two side rods and two end rods 3 pivoted together to allow change of shape of the frame and consequent relative sidewise movement of the cards 8. The frame 1 is pivoted to a base board 4 at the mid-points 5 of the side rods 2. The top edge of each card 8 is folded over and secured to itself to provide a sleeve 9 through which the wire 7 projects, and the ends of the wire are cranked to engage in apertures 6 in the upper faces of the rods 2. The sleeve 9 is cut away at its centre, and a small sleeve 10 of plastics material is fitted to the wire 7 at this point, to prevent sidewise movement of the card. In a modification, the two side rods 2 may comprise channel-shaped members with inturned flanges of scalloped form provided with scalloped-edge cover members fitted under the flanges, and the ends of the wires 7 are received in small block members removably retained in the channels. In another form, the sides 2 of the frame 1 comprise metal strips each curled at their outer edge to trap small nylon discs into which the ends of the wires 7 are fitted. Each card 8 is marked along its lower edge with divisions 12 which extend at right angles to that edge, and divisions 13, 14 along the side edges which extend obliquely to those edges. Thus, when the frame 1 is slewed in one direction so that it no longer forms a rectangle, one of the sets of divisions 13, 14 is exposed on all the cards, the oblique lines forming obliquely extending columns.

Date Oct. 16, 1997The invention concerns a control system for a plurality of groups of lifts (G1-G5), according to which system the passenger can input his destination at any destination call input device (TE) without having to know which group of lifts (G1-G5) serves the desired storey. In this way, in large buildings in which, for structural reasons, the ranges of storeys served by individual groups of lifts (G1-G5) are disposed adjacent one another in a confused manner, the passenger's search for the appropriate lift is facilitated. The multiple groups control system always selects the most favorable lift from all the available lifts and, when the storey ranges served by a plurality of groups of lifts (G4-G5) overlap, the selection is made from all the possible lifts. If the passenger has to change lifts, the connecting lift is shown on a display.

Abstract: PURPOSE: To let a male terminal be surely mounted to a specified position, and to make the aforesaid terminal small in size by inserting the first male terminal between elastic hold pieces at a first and a second side wall. CONSTITUTION: The orthogonal connection type relay terminal T2 is mounted to a first male terminal 12 from above. Namely, the terminal 12 is held by elastic hold pieces 1b and 2b in the plate thickness direction, and concurrently the terminal is brought into a condition where a first side surface 12a abuts against a fourth side wall 4, and furthermore a second side surface 12b is in contact with an elastic presser piece 3a. Subsequently, a second male terminal 14 is mounted to the terminal T2 from above. Namely, the second male terminal 14 is inserted between the second side wall 12b and the presser piece 3a of the terminal 14, and let the male terminal 14 be held by the side wall 12b and the presser piece 3a.  At this time, the terminal 12 is held in its width direction by the terminal 14 and the side wall 14, and the movement in its width direction of the terminal 14 is controlled by side walls 1 and 2. Thus as mentioned above, the insertion of the terminal 12 between the hold pieces 1b and 2b of each side wall 1 and 2 thereby allows the terminal 12 to be held, and it is held in the direction of plate thickness, and concurrently the movement of the terminal in the width direction is also controlled by the side wall 4 and the presser piece 3a.
