Title: Process for the manufacture of safranine dyestuffs
IPC: C09B17/04
Filed: 1935-08-14
Abstract: Safranine dyestuffs are manufactured by the aralkylation of the dyestuffs prepared according to the parent Specification by the condensation of aromatic 1 : 4-diamines which are not substituted in both amino groups and which contain in the 2-position an alkyl group or in the 2- and 6-position the same or different neutral substituents with isorosinduline-6-sulphonicacids having the formula <FORM:0461267/IV/1> in which R1 and R2 indicate alkyl, aralkyl or aryl groups.  The parent safranines may be sulphonated or the 1 : 4-diamines may contain sulphonic groups, but when an alkyl group is present in any of positions 11--15, the naphthophenazine residue must contain a sulphonic group.  In examples, benzylderivatives of the following safranines are prepared, using benzylchloride, nitrobenzylchloride, o-, m- or p-chlorbenzylchloride or 2 : 4-dichlorbenzylchloride as benzylating agent, in the presence of sodium bicarbonate, sodium acetate or pyridine: (1) the safranine obtained by condensing 1 : 4-diamino-2 : 6-dimethyl-5-sulphobenzene with the isorosinduline sulphonic acid derived from phenyl-b -naphthylamine and 4-nitroso-3-sulphodiethylaniline or 4-nitroso-3-sulphoethylbenzylaniline; (2) the safranine obtained by condensing 1 : 4 - diamino - 2 : 6 - dimethyl - 5 - sulphobenzene with the isorosinduline sulphonic acid derived from 2<1>-methylphenyl-b -naphthylamine and 4 - nitroso - 3 - sulphoethylphenylaniline; (3) the safranine obtained by condensing 1 : 4 - diamino - 2 - methyl - 5 - sulphobenzene with the isorosindulinesulphonic acid derived from 2<1> : 6<1>-dimethylphenyl - b  - naphthylamine and 4-nitroso-3-sulphodiethylaniline; (4) the safranine obtained by condensing 1 : 4-diamino-2 : 6-dichlor-5-sulphobenzene with the isorosinduline derived from phenyl-b -naphthylamine and 4 - nitroso - 3 - sulphodiethylaniline. The aralkylation improves the fastness of the dyestuffs to fulling and to seawater and the clearness of the greenish-blue shades obtained.

Patent GB-674802-A (GB)
Title: Improvements in or relating to electrical apparatus for comparing the phases of two alternating voltages
IPC: G05D3/14
Filed: 1950-09-20
Abstract: 674,802. Phase-difference measurements. SPERRY CORPORATION. Sept. 20, 1950 [Sept. 21, 1949], No. 23062/50. Class 37. [Also in Group XL (c)] Two conventional phase detectors are operated in parallel, the phase of the unknown voltage being advanced in one and delayed by an equal amount in the other, and the respective outputs combined in a polarity-sensitive double diode circuit. The phase of the input voltage applied to terminals 12, Fig. 3, is advanced in a phase shifter 13 and then applied to a phase detector 11. The same input voltage is delayed in phase by an equal amount by a phase-shifter 14 and then applied to the other phase detector 10, which is operated in parallel with the detector 11. The reference voltage is applied to terminals 9 which are connected directly with each phase detector. Fig. 4 shows the operating characteristics B, A of the two phase detectors 10, 11. The dotted curve C shows the output of the two phase detectors after their separate outputs have been combined in combining means 15 in which diodes 16, 17 are connected so that the output of the lagging phase detector 10 only passes through the diode 16 when it is positive, and the output of the leading phase detector 11 only passes through the diode 17 when it is negative. These conductive portions are shaded in Fig. 4, the combined output C having a broad null point of zero output. At the other cross-over point there is a period when both diodes conduct and overlap so that the combined output has a steep slope. This resolves any ambiguity as to the correct cross-over point. The combined output C appears across the terminals 18, Fig. 3. Instead of using two phase shifters 13, 14 only one phase shifter need be used, the other connection being made directly. Alternatively, the two phase shifters 13, 14 may be inserted in the reference voltage input instead of in the signal voltage input. Also a single phase shifter may be substituted for the two shown and alternately switched into each channel. Fig. 6 shows the application to an omni-azimuth navigation system in which coarse and fine signal sources 21, 22 are employed in conjunction with coarse and fine reference sources 23, 24. In a radio navigation system all these sources are in the craft's radio receiver. A coarse reference signal is supplied from the source 23 to a Selsyn transformer 29, which phase shifts it proportionally to the angle of the indicator 20. The three-phase output of the Selsyn 29 is converted to single-phase in a combining network 28, the output of which is then applied to phase detectors 10, 11. The output, as shown by curve C, Fig. 4, positions the indicator 20 by means of an amplifier 25 and motor 26 through a relay 30. When the indicator is positioned within the flat portion of the characteristic there is zero output in the coarse channel and the relay 30 is de-energized. The amplifier 25 is then connected to the output of the fine channel phase detector 31 for final adjustment.

Title: Safety control system
IPC: B30B15/14
Filed: 1977-06-01
Abstract: The press or punch has a drive device which has a coupling which can be actuated by pressure medium and service brakes which can be actuated by pressure medium, and in which the coupling and the service brakes are connected, by means of coupling and brake circuits which are constructed independently of one another, to a pressure generator via valves which can be alternately activated by control circuit contactors which belong to the safety control device. The control circuit contactors have forcibly guided contacts which are tested for pick up and drop out in each operating cycle. The operating device is provided with a follow-up monitoring circuit (24). Such safety control devices are essentially urgently necessary in machines into which material is manually inserted by the operating staff. The safety requirements are fulfilled in that signal transmitters (SK, SB1, SB2, SD) are locked onto the coupling, the service brakes and the pressure generator on the pressure medium feed and the contact breakers and contact makers (sk1, sb10, sb11, sb12, sb20, sb21, sb22 , sd1, sd2) are inserted, so as to be connected to the follow-up function, in the paths of the actuating current of the control circuit contactors (ES, K) and the follow-up monitoring circuit (24), and that the coupling and brake circuits are separated from the pressure generator at least once in each operating cycle as part of the procedures to test operational reliability. <IMAGE>
