Filed: 1974-03-06
Abstract: 1434162 Disazo pigments CIBA-GEIGY AG 6 March 1974 [7 March 1973] 10027/74 Heading C4P Novel disazo pigments of formula (where R<SP>1</SP> and R<SP>2</SP> independently are H, hal, CN, CF 3  or C 1-4  alkyl or alkoxy; or aryloxy, phenylsulphonyl or benzoyl optionally substituted by hal or C 1-4  alkyl or alkoxy; m and (n + p) are 1 or 2; X is H, hal, phenoxy, C 1-4  alkyl or alkoxy, NO 2 , CN, CF 3  or a carboxylic ester group; Y is H, hal, C 1-4  alkyl or alkoxy, NO 2 , CN, CF 3  or a carboxylic ester group; provided that when R<SP>1</SP> and/or R<SP>2</SP> is hal, (n + p) is 1 and when R<SP>1</SP> and/or R<SP>2</SP> is/are aryloxy, then the aryloxy group is not ortho to the azo group) are prepared by diazotizing the appropriate nitroaniline and coupling with the corresponding bisacetoacetyl-phenylenediamine. An example is given in which the two solutions are fed continuously to a mixing nozzle. The coupling may be carried out in the presence of dispersing agents and organic solvents and also the amine and coupling component may be reacted in an organic solvent using a nitrous acid ester to effect diazotization. Alternatively a diazoamino compound of the nitroaniline may be reacted with the bis-acetoacetyl-phenylenediamine in an organic solvent. The pigments are preferably heated in water or an organic solvent to modify their physical form. The pigments are used for colouring high molecular weight organic material, which may be in the form of plastic melts, spinning solutions, paints, lacquers, or printing inks.

Title: Improvements in or relating to wireless receiving apparatus
IPC: H03G5/04
Filed: 1937-04-08
Abstract: 487,451. Reproducing music etc.; wireless receiving systems. GENERAL ELECTRIC CO., Ltd., and BRITTAIN, F. H. April 8, 1937, No. 10028. [Class 40 (iv)] [Also in Group XL] A wireless receiver comprises two loudspeakers, one A having a relatively high cut-off frequency (curve e) and the other B having a relatively low cut-off frequency and having a peak in its response curve just before that frequency (curve f), with means for shunting one or the other as regards the higher audio-frequencies. In the arrangements shown, a condenser 4 may be shunted across either loud-speaker by a suitable switch. When A is shunted, the set gives good selectivity but imperfect fidelity of reproduction, whereas when B is shunted, the set gives good fidelity but poor selectivity. If the loudspeakers are connected in parallel, either of them may be cut out as regards the higher frequencies by means of a series inductance. The change-over switch may be ganged with a band-selecting switch in order to direct the higher frequencies to A when the set is adapted to receive a band subject to little interference.

Heading B7C. [Also in Divisions G1 and H1] In a device for indicating abnormal pressure in a pneumatic tyre and including an electric circuit there is provided a centrifugal switch 6 (see Division H1) to open the circuit when the tyre is stationary but permit it to be closed when the tyre has a rotary speed above a predetermined value. On occurrence of abnormal pressure a microswitch 4 is operated, by a plunger rod 13, the head 22 of which is subject to tyre pressure, to actuate a transmitter 3 powered by a battery 2 to give a radio signal which is picked up by a receiver in the driver's cab. In a modification (Fig. 7, not shown) a continuously-variable pressure-sensing device such as a solid state strain gauge replaces the switch 4 or is provided between the switches 4 and 6. The switch 4 may be a three-position switch to warn of both over- and under-inflation. Reference has been directed by the Comptroller to Specification 1,021,743.

Abstract: 1,173,067. Automatic control. HONEYWELL Inc. March 3, 1967 [March 4, 1966], No.10074/67. Heading G3R. A process variable is automatically controlled through a feedback amplifier by the difference between the magnitude of the variable and a set point signal, means being provided to ensure that, although changes in the variable have an immediate effect, changes in the set point are effective gradually. In Fig. 1, electrical signals dependent on the actual and desired values of a process variable are respectively applied at terminals 18, 16 and amplified by transistors 32, 24. The outputs of which are opposed so that any difference produces at a terminal 38 a potential of corresponding magnitude and polarity for application through amplifiers 46, 20 to a regulator 22 correcting the variable. R.C. networks 44, 70 in the forward path, and 66, 68 in the feedback path of amplifier 46, respectively provide integral and differential components of control. Network 44, 70 also serves to slow down the rate of application of any sudden change in the signal representing the desired value. A condenser 50 ensures that sudden changes in the actual value of the process variable are transmitted to the control system without delay. The proportional band of the control system is adjustable by means of a feedback potentiometer 58 and a meter 72 indicates deviations from the desired value.

In an open end spinning arrangement, fibres 4 are fed axially into a hollow cylinder 6 which is rotated at a specific speed and contains a helical coil 12 rotating in the same direction as the cylinder 6 but at a different speed. The fibres are thus pressed against the inner wall of the cylinder 6 and over the turns of coil 12 so that they rotate with the cylinder and are forwarded by the coil 12 towards the open end of the cylinder. The fibres are fed into the cylinder by rollers 1, 2 and preferably by an induced suction current in tube 3, see Fig. 3 not shown. The exit end of the cylinder is frusto-conical and is surrounded by a shield into which air is fed to assist in fibre withdrawal by an induced suction effect. The inner surface of cylinder 6 may be roughened or grooved to prevent the fibres slipping therein and it may be in the shape of an hour glass. The wire 12 may be of rectangular or halfcircular cross-section. As shown cylinder 6 is pressed against supporting wheels 8, 8a by a belt 9 by which it is driven, the weight of the cylinder being supported by a lip 10 on its upper end engaging wheel 8.

If the location is in none of the subsets, the local gazetteer is selected and displayed (Fig. 10, not shown); this display contains a pointer to the full gazetteer so that this can be selected directly if the location is not found. Otherwise, the display is "backspaced" (BS), a key "AUTRES DEST(inations)" is selected and a first level "index" display is obtained. A second level "index" is displayed on selection of a key, and a further selection of a key causes the appropriate page of the full gazetteer to be fetched from the host processor (Figs. 11-13, not shown).
