Patent GB-557077-A (GB)
Title: Improvements in or relating to electric signalling systems
IPC: G08B17/06
Filed: 1942-04-30
Abstract: 557,077. Fire alarm systems. STANDARD TELEPHONES & CABLES, Ltd., and BATES, E. F. April 30, 1942, No. 5819. [Class 40 (i)] In a system employing a closed metallic loop fed at the central station by a battery AB through supervisory relays A, B, in either leg and additional battery BB having one pole earthed connected to the loop to provide an emergency signalling circuit over either leg with earth return, both batteries are common to a number of closed loops. Each substation comprises normally closed signalling contacts SL, SE in the loop and in an earth connection which is completed over contacts KE when signals are to be sent. The relay B is preferably shunted by a rectifier MRB poled to prevent its operation in the loop circuit. The relays control tape recorders RE1, RE2, and it will be seen that if two substations send at the same time the relays will respond independently to the two signalling codes. The feature of "non-interfering succession" may be obtained, however, by connecting the two windings of the usual substation magnet in the loop and in the earth connection. The occurrence of a break in the closed loop causes the permanent release of relay A, closing an alarm circuit BL, and similarly the earthing of the loop causes the permanent operation of relay B, closing an alarm circuit EA. The contacts SL may be short-circuited by contacts BO which are opened when signals are to be sent.

Title: Tetracyano-benzoquinone-(1:4) and processes for its manufacture
IPC: C07C255/45
Filed: 1962-02-15
Abstract: The invention comprises tetracyanobenzoquinone and hydroquinone, the former being obtained from the latter by reaction with nitrous gases. The hydroquinone is prepared by contacting a compound of formula (I) <FORM:0977478/C1/1> with an alkali or alkaline earth metal cyanide in a C1- 4 aliphatic alcohol; X is halogen, alkoxy or NR1R2 which is a ring containing 2-5 methylene groups wherein the polymethylene chain may be interrupted by oxygen, or in which R1 and R2 are H, C1- 4-alkyl or phenyl-C1- 3-alkyl.  The compounds of the invention form complexes with aromatic compounds, in particular 1:1 complexes with pyrene; benzene, toluene, xylene, naphthalene and chrysene are also specified as complex-formers.  The hydroquinone gives a dimethyl ether with CH2N2.  Starting materials.  The dialkoxydicyanoquinones are formed by action of an alcohol or the 3,6-dihalogen compound or of a diazoalkane or the 3,6-dihydroxy compound.  The diaminodicyanoquinones are formed by action of ammonia or the appropriate amine on the 3,6-dihalogen compound or on the 3,6-dialkoxy compound, the latter method being used to prepare 2,5-dicyano-3, 6-dimorpholino, piperidino ethyleneimino and n-hexylamino-benzoquinones. The 2,5-dicyano-3, 6-dihydroxyquinone is formed by (a) hydrolysing (I) (e.g. X=Br, morpholine or O(Me) or (b) hydrolysing the reaction product of hydrogen halide and 2,5-dicyanoquinone. The latter compound is made by converting 2,5-dihydroxy diethyl terephthalate to the amide, alkylating the -OH groups, converting to dinitrile, dialkylating and oxidising with nitrous gases; it forms dicyanotetraacetoxy-benzene by reductive acetylation.  The 2,5-dicyano-3, 6-diiodo and difluoro quinones are made, respectively, by reaction of the dibromoquinone with NaI/acetone and of the dichloroquinone with KF/dimethyl sulphoxide. The dicyanodibromoquinone is prepared thus: 2,5-dimethoxy-3, 6-dibromo-diethyl-terephthalate, which is obtained by action of Br2/AlCl3 on 2,5-dihydroxy-diethyl-terephthalate followed by Me2SO4 is hydrolysed and converted to the diamide via the acid chloride, and then to the dinitrile which is demethylated with AlCl3/NaCl giving the desired hydroquinone which is oxadised with nitrous gases.ALSO:1: 1 complexes of pyrene with tetracyano-benzoquinone and tetracyanohydroquinone are described; complexes of these tetracyano-compounds with benzene, toluene, xylene, naphthalene and chrysene may also be formed.

Filed: 1929-02-22
Abstract: 329,398. Automatic Telephone Manufacturing Co., Ltd., and Blashill, T. Feb. 22, 1929. Vacuum or low-pressure apparatus, arrangements of. -An arrangement for producing pulsating currents for use in telephone and like systems comprises a neon lamp N connected in series with a relay A across a condenser C charged from a D.C. source 10, 11 through a resistance R<1>. When the condenser voltage reaches the striking voltage of the lamp N, current flows in the circuit of the relay A which operates the switch 13 to close the circuit 14 in which current impulses are required. The relay A also operates the switch 12, causing the condenser to be discharged through a resistance R. When the condenser voltage falls below the amount necessary to maintain the discharge in the lamp N, current in the relay ceases and the switches 12, 13 are returned to the open position. The cycle is then repeated to produce another impulse in the circuit 14. The frequency of the impulses produced may be varied from about 70 per second to one in five minutes by varying the rate of charge and discharge of the condenser by adjusting the resistances R, R<1>.

Abstract: 765,424. Re-fuelling and connecting aircraft. BOEING AIRPLANE CO. March 2, 1955 [March 5, 1954], No. 6197/55. Addition to 724,092. Class 4. In an improvement in the invention claimed in the parent Specification the boom is of aerofoil cross-section and is mounted for controlled rotation about its longitudinal axis whereby variation in the angle of incidence of the boom will cause it to be swung laterally by reaction with the ambient airflow. By this means a rudder at the trailing end of the boom is dispensed with though elevators are retained to move the boom up and down. The tanker aircraft T has a mounting 24 for a gimbal 21 which provides a universal mounting for a tube 13 in the leading end of an outer boom section 1 of aerofoil cross section which has mounted slidably within it an inner boom section 10, also of aerofoil section. A tube 11 carried by the trailing end of the section 10 engages a fitting 12 on a receiver aircraft R. The forward end of tube 13 carries a bevel gear engaged by a pinion driven by a motor 27 controlled by lateral movement of a control column 34 whereby an operator O can vary the angle of incidence of the boom so that its lateral position as viewed through a window W can be aligned with the fitting 12. Elevators 3 are mounted on a transverse axis at the trailing end of boom 1 and they are connected by cables to the column 34 so that the operator, by fore and aft movement of the control column, can adjust the elevators and so vary the up and down position of the boom. In a further embodiment a single elevator consisting of united swept-back surfaces is adjusted for pitch by controlled movement of tabs at the trailing edges and in a still further embodiment a plurality of pairs of elevators of high-aspect ratio are used.

During a change-over period of alternating regenerators 3, 3<SP>1</SP> traversed by either compressed gas mixture to be rectified e.g. air or by a reversely flowing cold separated gaseous component e.g. nitrogen the cold gas content of the off-stream regenerator e.g. 3 is discharged through a duct 20 to an auxiliary regenerator 3 thereby avoiding return of cold gas to the rectifying column (not shown) and after which discharge the regenerator becomes on-stream. In operation compressed air from a duct L traverses a valve 2<SP>1</SP>, the on-stream regenerator 3<SP>1</SP>, a non-return valve 9<SP>1</SP> and a line 8 leading to the rectification column whilst cold nitrogen gas from said column traverses a line 5, a non- return valve 6, the off-stream regenerator 3, a valve 7 and a line S, open to atmosphere ; valves 2, 7<SP>1</SP>, 9 and 6<SP>1</SP> being closed. To initiate change-over, valves 2, 2<SP>1</SP>, 6<SP>1</SP>, 9, 9<SP>1</SP> are closed and valves 21, 7<SP>x</SP>, 10 are opened whereby cold nitrogen is forced from regenerator 3 by the higher pressure in the compressed air charged regenerator 31 into the line S. To complete the changeover, valves 2, 6<SP>1</SP>, 7<SP>1</SP>, 9 are opened and valves 10, 21 are closed. The cold content of the so cooled auxiliary regenerator 3<SP>x</SP> is utilised by opening valves 2<SP>x</SP>, 9<SP>x</SP> thereby allowing incoming compressed air to traverse said exchanger 3<SP>x</SP>. In a modification using two auxiliary exchangers, the latter discharge the cold nitrogen into storage containers from which the cold gas flows back through the auxiliary exchangers to cool them after which it is added to the cold gas from the rectification column.
