Title: Coppered azo dyestuffs containing triazole residues
IPC: C09B43/00
Filed: 1961-11-27
Abstract: The invention comprises copper-containing azo dyes of formula <FORM:0954100/C3/1> wherein A is the residue of a diazo compound, which may contain a further azo group, in which X is in o-position to the azo group, X is an -O- or -COO- group, B is a p-phenylene or -naphthylene residue, D is an o-naphthylene residue, Y is a hydrogen or halogen atom, m is 0 or 1 and n is 1 or 2. The dyes may be prepared by the usual procedure, for example coupling the diazo compound of a suitable amine (A-NH2) which contains an -OH or COOH group or a group or atom convertible thereto under coppering conditions in o-position to the -NH2 group, with a 2-amino-5-naphthol-7-sulphonic acid, coppering the aminoazo dye obtained, diazotising the metal complex, coupling in p-position with an amino-benzene or -naphthalene, again diazotising and coupling in o-position to an NH2 group in a naphthalene azo component and finally triazolising the o-aminoazo compound. Alternatively by diazotising a 2 - amino - 5 - naphthol - 7 - sulphoric acid in which the hydroxy group is protected by acylation (e.g. with benzenesulphonic acid), coupling in p-position with an amino-benzene or -naphthalene, diazotising the aminoazo dye obtained, coupling with a naphthylamine and triazolising the o-aminoazo compound obtained. The resultant monoazo dye is saponified to remove the acyl group, coupled with a suitable diazo compound and coppered. The coppering reaction is carried out using aqueous copper sulphate and possibly ammonia and includes oxidatiol coppering and coppering with dealkylation. The dyes give brown and green shades on cellulose fibres. Examples describe the preparation of the dyes.

Title: Vehicle disc brake
IPC: F16D55/227
Filed: 1973-09-10
Abstract: 1387966 Spot-type disc brakes NISSAN MOTOR CO Ltd 10 Sept 1973 [12 Sept 1972] 42492/73 Heading F2E A spot-type vehicle disc brake having two pistons in a single cylinder hydraulically separated for brake application, one of the pistons abutting a directly-actuated friction pad assembly, has a generally-flat yoke movable parallel to the disc axis by the other piston to move an indirectly-actuated friction pad assembly, the yoke having a pad-engaging section which is bent in a direction parallel to the plane of the indirectly-actuated assembly, and whose edge bears against the indirectly-actuated assembly to ensure uniform contact with the disc on brake application. As shown, an hydraulic cylinder 12, Fig. 1, is secured to a structural part of a motor vehicle (not shown) and is open at both ends. An inner piston 16 abuts the backing plate 28 of a directlyactuated friction pad assembly 22 while an outer piston 18 accommodates a projection 36a of a flat yoke 34 having an opening 36. Edge 72 of opening 36 abuts the backing plate 32 of an indirectly-actuated friction pad assembly 24. The friction pad assemblies 22, 24, are guided in part by engagement of their ends with opposed edges 52, 54, of an opening 50 in a torquetaking structure 42 formed .by leg portions 44, 46, integral with hydraulic cylinder 12 and cross-members 48, 49. The friction pad assemblies are further guided by engagement of holes in their backing plates with guide pins 56 each having a head 58, and traversing a flange portion 48a of cross member 48. Bending of the yoke adjacent pad assembly 24 to produce depressions 70 results in edge 72 having an undulating profile, which ensures uniform contact with the disc and consequent even wear of the pad 30. Guiding of yoke 34 in a direction substantially parallel to the disc axis is ensured by annular supports 64, Fig. 2, each fixed in one of the depressions 70 and surrounding via a bushing 66 a guide pin 68 rigidly connected to cross member 48.

Title: Improvements in or relating to bistable circuits
IPC: H03K3/45
Filed: 1959-12-15
Abstract: 909,112. Magnetic amplifiers. WESTING- HOUSE ELECTRIC CORPORATION. Dec. 15, 1959 [Dec. 22, 1958], No. 42531/59. Class 40 (9). [Also in Group XL (c)] The output of a magnetic amplifier is used to trigger a bi-stable transistor circuit. As shown in Fig. 1, magnetic cores 41, 51, are driven from a centre-tapped transformer 15 and over rectifiers 45, 55 give a half-wave reversible polarity output across load resistor 60. Each core is biased to fire at 90 degrees by windings 43 and 53 so that no net current flows in load resistor 60. An input to windings 44, 54, produces unbalance in the firing angles one way or the other depending on input polarity and a corresponding polarity voltage pulse appears across the load resistor 60 during the difference between firing angles. If transistor 91 is conducting, transistors 81 and 110 are cut off. A pulse of one polarity across load resistor 60 will set transistor 81 conducting and voltage developed in the collector circuit is fed to the base of transistor 91 which is driven towards cut-off. Current fed to the emitters over resistor 85 is reduced and this drives transistor 81 to further conduction and transistor 91 further towards cut-off until 81 is fully conducting independently of the voltage from load resistor 60. With transistor 81 conducting transistor 110 conducts and provides an output signal. A signal of opposite polarity across load resistor 60 will cut-off transistors 81 and 110 and restore conduction in transistor 91. A magnetic amplifier to feed the bi-stable transistor circuit of Fig. 1, but one which gives a non-reversible full-wave output is shown in Fig. 2. The centre-tapped transformer 130 has a saturable core which fires at the mid-point of each half-cycle and consequently gives output only for the first 90 degrees of each half-cycle. Each core 151, 161 of the amplifier is biased by windings 154, 164, to fire at 90 degrees in each half-cycle so that in each half-cycle each core just reaches saturation and is driven no further. With an input to windings 153, 163, the firing angle of both cores is reduced to below 90 degrees and output appears from across load resistor 60. As an output of only one polarity is available the transistor circuit may be driven only one way by the amplifier and needs to be reset by other means. In both magnetic amplifiers bias may be produced by using resistor shunts across the self-excitation rectifiers.

Abstract: 1,104,146. Control of stepping motors. SMITHS INDUSTRIES Ltd. 23 April, 1965 [24 April, 1964], No. 43566/67. Divided out of 1,104,141. Heading H2J. [Also in Division G1] In the measurement of the expended life of a gas turbine engine in an aircraft (see Division G1), the measuring circuit produces saw-tooth pulses of constant amplitude whose frequency is related to the rate at which the life is expended. These pulses are supplied to a motor control circuit which causes the rotor shaft of a three-phase motor to perform one revolution for each pulse. When a pulse is applied to the base of transistor 21, Fig. 3, of the control circuit, the three stator phase windings 32, 34, 36 of the motor are energized in turn to complete one revolution of the rotor shaft, by causing pairs of transistors 25, 31, 22, 33, 23, 35 to become conductive in succession. The successive energization of the pairs of transistors is brought about by connecting the bases of transistors 22, 23, 24 to earth through diodes 27, 28, 29, 30, which are biased to become conductive when the potential of the base of the respective transistor reaches a value of - V, - 2V, - 3V respectively, the amplitude of the pulses at the emitter of transistor 21 being - 3V.
