Patent GB-487877-A (GB)
Title: Process for the manufacture of new anthraquinone derivatives
IPC: C09B5/00
Filed: 1936-12-30
Abstract: Anthraquinone derivatives are manufactured by reacting benzyl cyanide with an anthraquinone substituted in 2-position by a cyano group and in 3-position by a carboxylic acid, amide or ester group, preferably in the presence of a condensing agent, e.g. cuprous cyanide, or by heating benzyl cyanide for a long period with a corresponding 2-halogenanthraquinone compound in the presence of cuprous cyanide. The products are starting materials for the manufacture of dyestuffs. In examples: (1) 2-chloranthraquinone-3-carboxylic acid methyl ester is heated with cuprous cyanide and excess of benzyl cyanide; (2) 2-cyanoanthraquinone-3-carboxylic acid methyl ester is heated with benzyl cyanide; (3) 2-chloroanthraquinone-3-carboxylic acid is treated as in (1); (4) 2-chloroanthraquinone - 3 - carboxylic acid amide is similarly treated.  2 - Cyanoanthraquinone - 3 - carboxylic acids, esters and amides are obtainable by diazotizing 2 - aminoanthraquinone - 3 - carboxylic acids, introducing a cyano group by the Sandmeyer reaction, and, if desired, esterifying the products or converting them into their amides. 2-Cyanoanthraquinone-3-carboxylic acid methyl ester is obtainable by heating the corresponding 2-chloro-compound for a short time with cuprous cyanide in benzyl cyanide.

Abstract: 1,004,825. Commutation arrangements for dynamo - electric machines. LICENTIA PATENT-VERWALTUNGS-G.m.b.H. Oct. 20, 1961 [Nov. 14, 1960; July 11, 1961], No. 37695/61. Heading H2A. [Also in Division G3] In a D.C. motor having controllable rectifiers in place of the commutator the rectifier ignition angle is varied depending on the error between a reference current and the actual current in each phase winding and the sign of the reference current is changed when the relevant winding crosses the gap between the poles. As shown, rectifier groups 9, 10 are arranged in counterparallel connection which permits operation as a motor with regenerative braking and have their control electrodes connected to 509, 510, respectively. Current transformers 6 are used to measure the current flowing through each pair of rectifiers and a reactor 8 is used to limit the circulating current. The ignition angle of the rectifiers, which may be solid state devices, is controlled to null the difference between the phase current i 1 , i 2  and a reference current which is proportional to the variation in speed of the machine from a desired speed. The basic commutation is obtained by scanner 3 in conjunction with a coloured screen 14 and is superimposed on the speed control system to alter the sign of the reference current. The motor may be used in weak-field operation and the scanning device may determine the position of the rotor by electrical or magnetic means using control commutators, Hall devices or auxiliary pole systems on the rotor. The reversal of polarity need not take place abruptly and a scanning device having a continuously varying output may be used. Damping windings may be used on the armature.

Class 100(4) An ink-ribbon feed reversing mechanism operated by the increased ribbon tension when a spool is exhausted comprises spools 11, 65 rotated by pawls 43, 53 engaging ratchet wheels 10, 52 and held by arresting pawls 24, 51. Each spool has a ribbon guide lever 21, 50 over which the ribbon 44 passes and the ribbon is arranged to form an acute angle over the lever 21 of the exhausted spool and an obtuse angle over the lever 50 of the full spool so that the increased tension has a maximum operating force. The increased tension will from the position shown rock the guide lever 21 to the dotted line position during which movement by its engagement of a flange 19 will move a reversing lever 12 until a spring 16 forces it, and by a connecting link 29 a reversing lever 30, to the reverse feed position. In the new position the lever 12 will have its arm 28 out of engagement with the pawls 24, 43 which engage the wheel 10 and start to feed the spool 11 in the reverse direction while an arm of the lever 30 will cam the pawls 51, 53 away from the ratchet wheel 52. Catches 33, 47 are frictionally rotated by their associated spools so that the active feed spool guide lever 50 is locked by engagement of a projection 48 with an abutment 49 while the latch 33 leaves the guide lever 21 free to make the reversing movement described.

Abstract: 1322217 Controlling suspension height AISIN SEIKI KK 5 Aug 1970 [5 Aug 1969 6 Aug 1969 8 Aug 1969] 37871/70 Heading B7D [Also in Division F2] A self-levelling piston-cylinder vehicle suspension unit is provided with a number of predetermined levels, a selected one of which is brought into operation by the electromagnetic, electrical or hydraulic operation of a corresponding valve or valves actuated manually by the driven or automatically as a function of the vehicle speed or frequency and amplitude of vibration. Levelling takes place via a plurality of openings 40a, 40b &c. in the cylinder wall 12, each of which communicate independently with a reservoir 42 by way of a valved passage 41 (41a, 41b &c.). With the top passage 41(a) open, a pump piston 18 functions, by means of valves 34 and 33, to keep the working piston 13 at the level of the top opening 40a. With the passage 41(a) closed by the valve element 47, the unit will instead maintain a constant height corresponding to the piston 13 being at the second opening. Oscillations of the piston 13 are damped by valves 19, 20 which damp liquid flow from the working chamber 31 to a high pressure chamber 24 and vice versa. The level determining valves are electromagnetically operated solenoid valves actuated manually by the driver. They may instead be hydraulically operated. Instead of being actuated manually, the valves may be actuated automatically in response to vehicle speed either by an hydraulic governor (Figs. 5-8, not shown), or by the voltage induced in a generator (Figs. 9, 10, not shown), so as to give a low riding height at high speeds and vice versa. Alternatively (Figs. 11-14, not shown) the valves are actuated automatically in response to the frequency and amplitude of vibration by means of a voltage developed by the oscillations of a magnet (200) on the piston-rod housing.

If a counter of the type in which only one stage should normally be operative has two or more stages operative then operation of the counter is inhibited. Magnetic cores F1-Fn2 each have setting, bias, output, and resetting windings 1-4, respectively, halfdrive currents being applied to 1 and 2 so that both need to be energized to set a core. The cores are interconnected by flip-flops T1- Tn2, each of which is set to condition 1 by the associated core when set and restored when the next core is set. The odd and even setting windings are energized by anti-phase pulses, respectively, on leads 7, 8 so as to advance the count from an odd to an even stage and vice versa. The last stage is connected to the first to form a ring. The outputs PD of all stages except the first are connected to an inhibit winding 16 on the first core S1 so that if two or more of these stages is operative when shift to the first stage is attempted the counter stops. An alarm may be given. The circuit is set to initial condition by circuit 5.
