Title: Copper phthalocyanine pigments crystallisation- and flocculation-resistant in the -form and process for their manufacture
IPC: C09B67/22
Filed: 1960-09-28
Abstract: The invention comprises copper phthalocyanine pigments in the a -form and in a state of dispersion suitable for pigmenting purposes which comprise intimate mixtures of at least 80% of copper phthalocyanine and/or copper monobromo- or monochloro-phthalocyanine, 0.5 to 10% of tin phthalocyanine and 0.5 to 10% of cobalt phthalocyanine. Small proportions tions of other metal phthalocyanines may be present. The tin and cobalt phthalocyanines specified are dichloro-tin, hydroxy-tin and chloro-cobalt phthalocyanines. The pigments are made by grinding the a - or b -form of the copper phthalocyanine and/or copper mono-chloro- or mono-bromo-phthalocyanine, tin phthalocyanine and cobalt phthalocyanine to produce the a -form before, during or after mixing them together. Grinding may be conducted in the presence of an inorganic or organic salt or a solid organic compound capable of subliming. Mixing may be effected by grinding or acid-pasting the components together or by synthesizing them together. A mixture of the pigments in b -form may also be converted to the a -form by acid-pasting from concentrated sulphuric acid. Examples are given. The pigments are crystallization- and flocculation-resistant. Specification 971,044 is referred to.
Patent ES-293203-A1 (ES)
Title: Radio receiver
IPC: H04B1/16
Filed: 1963-11-05
Abstract: In a receiver for a stereophonic radio signal the means for reconstituting the subcarrier signal from the received pilot signal includes a normally cut-off valve which is rendered conductive after a predetermined delay on the reception of the pilot signal. By this means the receiver is switched automatically from monophonic to stereophonic reception and noise is reduced when tuning between stations. As shown in Fig. 1, the sum signal L+R, the difference signal L-R amplitude modulated on a suppressed subcarrier wave, and a pilot signal of half the frequency of the subcarrier, are provided at the output of the F.M. receiver and discriminator 12, the pilot signal of 19 kc./s. developed across the tuned circuit 18, 20 being supplied to the control grid of valve 22. The output of the valve 22 is supplied via transformer 26, whose secondary winding is tuned to 38 kc./s., to the control grid of a valve 35 and the resulting subcarrier signal is supplied via transformer 45 to the demodulating circuit comprising diodes 70, 71 for one output channel and 80, 81 for the other. The oppositely poled diodes 70, 71 are fed with opposite phases of the subcarrier so that at the junction of resistors 74, 75 the subcarrier is balanced out but at this point the demodulated difference signal is combined with the audiofrequency sum signal to produce the left audiofrequency signal which is supplied via capacitor 77 to the amplifier 60. The diodes 80, 81 operate in the same way to supply the right audiofrequency signal to the amplifier 62. The valve 35 in the frequency-doubler circuit is biased to cut-off by voltage divider 85, 86 in the absence of a pilot signal. When the pilot signal is received it is rectified by diode 92 and the resulting voltage overcomes the cathode bias of valve 35 and allows it to conduct. RC circuit 94, 97 ensures that switching takes place only when the pilot signal has been present for a predetermined period. Neon tube 49 provides an indication when a stereophonic signal is received. An alternative rectifying circuit for the pilot signal is described, Fig. 2 (not shown).

Abstract: Defects in the bottom of transparent containers are detected by focusing at least one beam of radiant energy on to the bottom of the container, rotating the container, and providing a plurality of axially spaced distinct radiant energy paths so that a defect reflects radiant energy along at least one such path to detector means. Containers C, Fig. 1, are moved to an inspection station 12 where they are raised and rotated by a vacuum pad 13 to a position where the bottom is illuminated by upwardly directed light beams L 1 , L 2 , L 3 , L 4 . Defects such as bottom checks reflect light upwardly to a detector unit 25, which comprises collimating slots 27, Fig. 9, which diverge from the focal point of beams L 1 , L 2 , L 3 , L 4 , and an array of parallelly connected photovoltaic cells 29. An output from the detector unit 25 may energize a reject solenoid, after a delay if necessary.

Title: Flow control device
IPC: F16K5/02
Filed: 1968-06-01
Abstract: A valve device for controlling the supply of fuel gas to a main burner 18, comprises a manually operated valve member 32 which has a flow chamber 37 with an inlet port 38 cooperating with a port 12 in the valve housing and an outlet port 44 regulated by a second valve member 64 in response to the outlet pressure. This pressure is communicated through the hollow valve member 64 to a chamber 82 between a balancing diaphragm 70 and an actuating diaphragm 84 which, as shown, is adjustably spring loaded. Gas to a pilot burner 24 in pilot lighting and full flow positions of the conical plug type manual valve 32 is permitted through respective ports 42, 39. The device includes a safety cut-off valve (not shown) in the valve housing inlet, controlled by a thermocouple 26. The device also includes a conventional thermally-actuated valve (48), Fig. 2, upstream of the main outlet (14). This may be actuated by a rod and tube thermostat (60) inserted in a hot water tank. In a modification, the spring loading of the actuating diaphragm 84 is replaced by a fluid pressure loading in accordance with a regulated pressure supplied to the pilot burner. The pilot pressure in this case is regulated by a spring-loaded diaphragm valve (110), Fig. 3 (not shown) which is responsive to the downstream pressure and communicates on the upstream side with the ports 39, 42. The valve plug 32 is retained by a spring plate.

Title: Method and device for reducing yarn defects on an open end spinning system
IPC: D01H13/22
Filed: 1968-12-12
Abstract: A device for stopping spinning in an openend device upon the occurrence of a thick part in the produced yarn comprises a device such as a tube 3c through which individual fibres are carried in an air flow to the chamber 4, a duct 10b whereby compressed air is fed to tube 3c to produce the air flow, an electromagnetic valve 10a in duct 10b and means downstream of chamber 4 to detect a thick part in the yarn and cause valve 10a to be actuated to stop the supply of compressed air and thus halt the spinning process. As shown a slit is provided between plates 9a, 9b spaced so that a thick part is caught and the yarn broken this allows a biased feeler 8b to swing sideways, and operate a switch which causes valve 10a to be operated. A suction nozzle 21 catches the loose end of yarn and prevents it being drawn back into the spinning chamber by centrifugal force. A second biassed feeler 8c is provided at the exit of the spinning chamber to stop the supply of compressed air should the yarn break or become weak and slack in this region. In Fig. 2 not shown the slit flats (19a, 19b) are inclined to the yarn so that when a thick part engages the slit the yarn is deflected sideways to shift a feeler (8b) and close valve 10a. In Fig. 4 not shown the slit is at one end of a plate pivoted about a horizontal axis. When a thick part engages the slit the plate is pivoted against a biassing spring thus releasing a switch which closes valve (10a).
