Patent GB-882138-A (GB)
Title: Improvements relating to substituted cyclohexanes and cyclohexadienes
IPC: C07F9/50
Filed: 1959-09-21
Abstract: The invention comprises substituted-cyclohexanes and -cyclohexadienes of the general formula <FORM:0882138/IV (b)/1> wherein the Q's are carboxyl groups or groups hydrolysable to carboxyl, and Y represents <FORM:0882138/IV (b)/2> or <FORM:0882138/IV (b)/3> The compounds are suitable as active ingredients in thermographic copying papers (see Group XV).  In Example 1, cyclohexan-1,4-dione is heated under reflux with malononitrile, in the presence of benzene, acetic acid and ammonium acetate (as catalyst), until the theoretical amount of water has been removed.  The product is 1,4-bis (dicyanomethylene) cyclohexane.  This is brominated with N-bromosuccinimide, and the intermediate is then dehydrobrominated with ethereal pyridine to give 1,4-bis (dicyanomethylene) cyclohexadiene.  Example 2 states that both dicyanomethylene-cyclohexane and -cyclohexadiene may be hydrolysed, by sulphuric acid or sodium hydroxide solution, so that 1,2,3 or all of the cyano groups are converted to carboxyl groups. The carboxylic acids can be converted into the acid chlorides by treatment with thionyl chloride; and the acid chlorides can be converted into the acid fluorides, bromides or iodides by interchange with HF, HBr or HI in the presence of the corresponding alkali metal halide.  For example, 1,4-bis (dicarboxymethylene) cyclohexane reacts with thionyl chloride to yield 1,4-bis (dichlorocarbonyl methylene) cyclohexane which is then treated with sodium hydrogen fluoride to yield 1,4-bis (difluorocarbonyl methylene) cyclohexane.  1,4-bis (disubstituted methylene) cyclohexanes wherein the substituents are ethoxycarbonyl, carbamoyl, cyano (ethoxycarbonyl) or cyano (carbamoyl) can be prepared by replacing the malononitrile of Example 1 by diethyl malonate, malonamide, ethyl cyanoacetate or cyanoacetamide, respectively.  Examples 4 and 5 relate to the reduction of 1,4-bis (dicyanomethylene) cyclohexadiene, with thiophenol and mercapto-acetic acid respectively, to give 1,4-bis (dicyanomethyl) benzene.  The invention also comprises complexes of 1,4-bis (dicyanomethylene) cyclohexadiene with Lewis bases. Examples 6 and 7 describe the preparation of complexes with 5,8-dihydroxyquinoline and 2,5-diaminodurene, respectively, wherein the molar ratio of tetracyano-compound to Lewis base is 1 : 1.  The Specification includes a table setting forth details of complexes formed from other specific Lewis bases.  The complexes are coloured, and those with the stronger Lewis bases are paramagnetic and may be used as inks (Group XV).

Title: Improvements in or relating to coumaran derivatives
Filed: 1953-11-19
Abstract: The invention comprises coumaran derivatives of the formula <FORM:0741645/IV(a)/1> where X is -O-, -CH2-, -CO- or a direct linkage, and R is a tertiary amino radical, and salt thereof.  They are made by treating the compounds (R = Hal; see Specification 741,648) with secondary amines in the presence of acid-binding agents, preferably excess of the secon dary amine.  Salts are formed by treatment with the appropriate acid.  Examples show the preparation of bis-(2-piperidinomethyl-5-coumaranyl), bis - (2 - piperidinomethyl - 5 - coumaranyl) - methane, bis - (2 - piperidinomethyl-5 - (coumaranyl)-ether, bis-(2-piperidinomethyl-5-coumaranyl)-ketone and bis-(2-morpholino-methyl - 5 - coumaranyl)-ketone, and their hydrochlorides.  R may als be a dialkylamino group such as dimethylamino or diethylamino.

Circular knitted ladder resistant fabric, e.g. as shown in Fig. 1 of Specification 989,186 comprises a short thread length course (b) in which all needles knit and a long thread length course (a) in which every second or predetermined needles pass through the feeder at such a height that they hold the stitches of course (b) and receive tuck loops of course (a) on their stems, course (a) being drawn on a higher sinking point than course (b) so that when the succeeding course is knitted, the tuck loops and the held stitches form tuck stitches, the held stitches being enlarged to match the tuck loops and hence robbing thread from the remaining stitches which form locking stitches, the needle selection being altered after every two courses so that tuck stitches in successive courses (a) do not appear in the same wales. Preferably the thread length of course (b) is 70% or less of that of course (a) and this difference is achieved by lowering one needle cam or moving the sinkers inwards further and earlier than usual. As shown, course (a) is drawn on top of the sinker hook p<SP>h</SP> and course (b) is drawn behind the sinker hook on level P<SP>a</SP> or level P<SP>b</SP> if sinker is shaped as shown by the dotted line.

Title: Improvements in automatic weighing machines
IPC: G01G13/00
Filed: 1937-12-01
Abstract: 506,649. Sorting articles or controlling operations by weighing. POPOV, V. D. Dec. 1, 1937, No. 33193. Convention date, Dec. 2, 1936. [Class 143] In a method of automatic weighing wherein after.release of a scale beam a feeler is moved towards the beam to determine the performance or otherwise of work in relation to the article or material being weighed, work is performed if the feeler misses the deflected beam, but if the-feeler engages the beam the work is prevented owing to deflection of the feeler to an inoperative position or owing to a resilient connection in the driving mechanism of the feeler. As shown in Fig. 1, the scale beam carries a loose knife-edged blade 17 adapted to co-operate with a pointed feeler 12 pivotally mounted on a cam-operated lever 11. An arm 12b of the feeler rests upon an abutment screw 13. In comparing the loads P, Q, at the opposite ends of the scale beam, cams 9, 15 first lower-the arresting fork 6 to free the beam, allow an interval for the beam to assume a position of equilibrium, move the feeler 12 towards the blade 17, withdraw the feeler and again raise the fork 6 to hold the beam. If the load P is smaller than Q or the loads are substantially equal the beam rises or remains horizontal and the feeler 12 during its advancing movement misses the blade 17 and, with its arm 12b, rocks a lever 21 to furnish mechanical energy or press an electric contact 22 for the purpose of doing work, for example, removing the rested article and putting a fresh one in its place or for causing the addition of a further light dose of material as described in Specifications 445,876 and 445,928. If the article P is heavier than Q, the feeler 12 strikes the blade 17 and the arm 12b is raised and fails to engage the lever 21. in which case the article is automatically removed to the heavy article position. If the points of the feeler 12 and blade 17 meet, the feeler and the blade are both rocked upwards thus preventing damage to the fulcrum 2 of the beam. In a modification, Fig. 9, instead of a pivoted feeler, the feeler 11b is integral with the lever 11, and the lever is actuated by its cam through a spring 11a. The loose blade 17 is also replaced by the integral end of the beam. In order to prevent faulty movement of the beam due to adhesive contact of the fork 6 when this is removed from the beam, a weighted lever 23, Fig. 14, is arranged to press lightly on the end of the beam but, after release of the beam, is automatically removed by a connection with the fork-actuating mechanism. In a modification, Fig. 15 (not shown), the weighted lever 23 and the pivoted feeler are arranged to move and operate in an upward direction. Specification 11509/13, [Class 143], also is referred to.
