Abstract: 1402011 Pigmented compositions BADISCHE ANILIN- & SODA-FABRIK AG 29 June 1972 [30 June 1971] 30479/72 Headings C3F C3P and C3R [Also in Division C4] Polymer or cellulose-based inks and lacquers contain an organic pigment paste of high frictional strength obtained by treating a finely particled crude organic pigment at from room temperature to 200‹ C. with an organic solvent or mixture thereof suitable for use in a printing ink or paint or with a similarly suitable resin solution, the treatment being carried out in the absence of grinding aids and high shear forces until the pigment attains optimum pictorial properties (see Divisions C4-C5). The crude pigment may have been obtained directly by synthesis or by subsequent comminution with or without grinding aids. Numerous organic pigments, organic solvents and natural and/or synthetic resins are specified. The crude pigment may be scattered or stirred into the organic solvent or resin solution and then treated at from room temperature to 200‹ C. for a time between a few minutes and several days, optionally with the use of a simple stirrer, until optimum frictional properties are attained. Examles are as follows:- (2) Cu phthalocyanine (pc) is stirred at 70‹ C. with nonyl phenol and mineral oil, and the product is stirred with modified rosin, mineral oil and an oil-modified alkyd resin to form a print paste; (4) Cu pc. is treated with toluene and ethanol at 70‹ C. and the paste is then dispersed in nitrocellulose; (5) the paste obtained in (4) is dispersed in vinyl chloride vinylacetate copolymer solution; (6) the paste obtained in (4) is stirred into a polyamide solution to give an ink; (8) a flavanthrene pigment is stirred at 40‹ C. into a varnish comprising an alkyd resin, xylene, a urea-formaldehyde resin, butanol, and ethylene glycol, and the mixture is then further dispersed in a ball mill; the product is then mixed with a titanium dioxide varnish and baked; (9) an azo pigment derived from paminoazo benzene and perylene-3,4,9,10-tetracarbocyclic acid is stirred at 130-135‹ C. into ethylene glycol monoethyl ether, and the product is dispersed in a varnish comprising an alkyd resin, a urea-formaldehyde resin, xylene and butanol; (10) a chlorinated Cu pc. is stirred at 50‹ C. in a varnish comprising alkyd and urea-formaldehyde resins, xylene, butanol and ethylene glycol and the varnish is then ballmilled; (11) Cu pc. is stirred at 90‹ C. in a ketone resin solution in xylene, butanol and ethyl glycol and the paste is stirred into a mixed acrylate/ melamine varnish in butanol and xylene; (12) a condensation product of p-chloroaniline and perylene-3,4,9,10-tetracarboxylic acid is ballmilled into a varnish containing alkyd and melamine resins, xylene, butanol and glycol monoethyl ether.

Title: An improved device for preventing chatter of movable elements, such for example, as the selector bars of teleprinting machines and the like
IPC: H04L13/16
Filed: 1934-10-24
Abstract: 431,618. Type - printing telegraphy. SIEMENS & HALSKE AKT.-GES., Siemensstadt, Berlin. Oct. 24, 1934, No. 30505. Convention date, Nov. 9, 1933. [Class 40 (iii)] To prevent chattering of a moving part such as a selector bar 1 of a type-printing receiver, a weight 2 is mounted on the part with frictional engagement. Thus when the part 1 moves to the right the weight 2 also is thrown to the right by friction or by the pin 3, but when the parts 1 is stopped by the pin 5 the weight continues to move to the right, pressing the part 1 against the pin 5 by friction and so preventing it from rebounding.

In the form shown in Figs. 1, 5, the fixed magnet 5 is mounted within the coil body 1 and the movable armature 5<SP>1</SP> is attached by a pin 12 to a stirrup 7 fixed to a pin 8 which extends into the contact body 2 and carries loosely a three-armed member 9 biassed by a spring 10. The member 9 has clamped to the end of each of its arms a strip with end contacts 16 adapted to engage fixed contacts 19. The armature is urged downwards by springs not shown and the casing may be filled with oil. A plate 3 between the units 1, 2 serves to shut off the contact-chambers 4. The armature carries an auxiliary contact 14. The Specification as open to inspection under Sect. 91 comprises also, Fig. 10 (Cancelled), an oil switch with the contact unit 2 at the bottom and connected to the magnet unit 1 by arms 24.

Filed: 1974-07-12
Abstract: 1469864 Integrated circuits THOMSON CSF 12 July 1974 [13 July 1973] 31092/74 Heading H1K The components of an integrated circuit are compensated against temperature drift effects by the incorporation into the same semiconductor substrate of a supplementary component exhibiting a temperature-dependent characteristic and feedback means connecting the supplementary component to the supply for the main components. In Fig. 2 the substrate terminal Q of an FET2 is supplied from an amplifier 20 across whose input is a supplementary diode 4 the forward-biased threshold voltage of which varies with temperature. The amplifier 20 may be replaced by a differential amplifier (30), Fig. 3 (not shown), with one input (31) connected to the supplementary diode (4) and the other (32) connected to a variable voltage source (37). The first input (31) is also connected to the output (34) through a variable resistor (36), and the two variable elements (36), (37) allow the response of the amplifier to be adjusted. In a modification of this embodiment the second input (32) of the differential amplifier (30) is connected to a supplementary diode (62), Fig. 6 (not shown), in a second wafer set in a constant temperature housing. In all cases the supplementary diode 4 may be replaced by an FET having its source and gate connected, the temperature-dependent characteristic in this case being the drain current. When a plurality of I.C. wafers are mounted in a common casing temperature compensation of all wafers can be effected by means of a temperature-dependent supplementary component in just one wafer.

The layers are contained within an outer shell e which leaves exposed one surface of one of the medicament layers. This shell is made of a material which resists disintegration in vivo, at least until the or the last inert layer has disintegrated, so that medicament is not released from succeeding layers until some time subsequent to depletion of the layer(s) first subjected to body fluids. The layered structure may be made by conventional compression techniques and the shell, which may be made of synthetic plastics, e.g. PVC, polyethylene or polypropylene, a wax or a cellulose derivative, may be preformed and heat-shrunk on to the core, applied by dip coating or by compression coating. A protective but disintegrable layer a may be applied to the exposed medicament layer surface.

[Also in Division G1] A thermostat for a domestic iron utilizes the differences in expansion between the base plate 1 of the iron and a reference member 2 of a material with a low coefficient of thermal expansion, e.g. " Invar " (Trade Mark), to open and close switch contacts 9, 10 in the heater circuit of the iron. At one end the reference member 2 engages a cranked member 17 by means of a suitable pin 16 secured thereto. The member 17 is pivoted in a fixed plate 19 and also carries a small bimetallic strip 22 bearing on a flanged adjustment nut 23. The position of the nut 23 controls the temperature at which the thermostat operates and the bimetallic strip 22 compensates for any minor expansion of the member 2.
