Title: Non-crystallizing phthalocyanine coloring matters
Inventor: MOSER FRANK HANS
IPC: C09B47/10
Filed: 1961-10-13
Abstract: A non-crystallizing phthalocyanine is made by contacting an acid-pasted dry powdered copper, iron or metal-free phthalocyanine having an average of from zero to eight chlorine atoms per molecule, with chlorine to produce a chlorinated phthalocyanine having on average at least about 0.5 atoms of chlorine per molecule more than the starting material.  A noncrystallizing, non-flocculating phthalocyanine is obtained by mixing about 5 to 20% by weight of a phthalocyanine monosulphonic with the above chlorinated phthalocyanine in a water slurry and drying the mixture.  The chlorination may be effected by reacting chlorine with the dry dyestuff alone or in a slurry of an inert chlorinated hydrocarbon such as carbon tetrachloride. Examples are given.  In a comparative example, a non-crystallizing phthalocyanine made by the chlorination process is heated with sulphuric acid, drowned, boiled with water and mildly treated with alkali with the loss of noncrystallizing properties.  Specification 703,507 is referred to.

Abstract: 1,189,167. Machine tool details. EUROPEAN ATOMIC ENERGY COMMUNITY. 15 Aug., 1967 [15 Aug., 1966], No. 37532/67. Headings B3B B3C, and B3K. Grooves or radial holes are milled or drilled into the walls of a tube 1, by a rotating cutter 7, adjustable along its own axis, and also along the axis of the tube, the latter movement being controlled by a template 14, the holes and slots 14a-14e of which co-operate with a follower 8, the template and tube being mounted in a jig 9, after the removal of a setting gauge 13. Cutter 7 is driven by a turbine 7a supplied with air through ducts 7h, 7i, and mounted for radial movement against the action of springs 7c, 7d in a sleeve 5, guided on a pin 3 located in a collet 2c. A rack 4e operated by a micrometer nut 4f slides in a groove 4c and actuates a cam 4i for moving the cutter radially, to vary the depth of cut, and milling pressure. Follower 8 is clamped in groove 4c of sleeve 4a, the latter being rotatable and axially movable on pm 3, and the whole assembly is mounted in the tube to be machined and supported on jig 9. The jig comprises clamps 11, and a specimen tube gauge 13 for setting template 14. The latter is mounted on a compound slide 15, and a further compound slide 16 accommodates one end of the machining apparatus, the V-block 17 of slide 16 being in contact with a shoulder 4b of the apparatus. When a finned tube is to be machined, the correct rotational position of the tube relative to the template is controlled by a locating device 18, which engages in a groove or grooves between the fins. An ammeter indicates when the cutter engages the internal wall of the tube.

Title: Improvements in or relating to viscometers
IPC: G01N11/02
Filed: 1963-09-24
Abstract: 1,097,753. Viscometers. K. WEISSENBERG. Sept.23, 1964 [Sept. 24, 1963], No.37579/63. Heading G1S. Apparatus for measuring the flow properties of a liquid comprises liquid discharge means mounted for movement in a chosen direction and arranged to provide at least one restricted flow of liquid therefrom to cause movement of the discharge means, the liquid being supplied at constant pressure from a reservoir of liquid, counteracting means such as gravity arranged to oppose said movement, and means for measuring the displacement of the discharge means upon efflux of the liquid to give an indication of the back pressure exerted on the discharge means by the liquid efflux. In the first embodiment, the discharge means comprises a container 10 filled to a constant level X with the liquid under test. The container is supported by a spring 14 to permit vertical movement so that as the liquid discharges through an orifice 13 in the base of the container, the upwardly directed back pressure can be measured by the altered strain on the spring caused by said movement which is measured on the scale 16. The orifice may be at the base of the side wall of the container so that the back pressure exerts a rotating force on the container which is freely pivoted about a horizontal axis. The container may be divided into two separate compartments each with an oppositely directed orifice, one of the compartments being filled with a standard liquid and the other with the liquid under test so that the resulting movement gives a measure of the ratios of the kinematic viscosity of the two liquids. In another embodiment the container is suspended for rotation about a vertical axis and has a number of equally spaced orifices directed tangentially to the axis of rotation. In a further modification (Fig. 5), the container 29 is held fixed and the liquid is discharged through a capillary assembly which is mounted for rotation about a vertical axis. The capillary assembly shown comprises three inverted U- shaped capillaries with one leg of each longer than the other, the shorter leg dipping into the liquid in the container and the longer leg passing through an opening in the centre of the container. The bottom end of each longer leg is bent so that the jet is ejected horizontally and tangentially to the axis of rotation of the assembly. The pressure on the liquid in the capillary may be varied by changing the lengths of the legs.

Abstract: 1,270,737. Supervising repeaters. C.I.T.- COMPAGNIE INDUSTRIELLE DES TELECOMMUNICATIONS. 6 Aug., 1970, No. 38014/70. Heading H4R. In a transmission system comprising a transmission cable incorporating a number of parallel four wire lines and repeater units at spaced intervals along the cable, each repeater unit including a repeater for each line, and each repeater including go and return portions and means to interconnect these portions to loop the line for monitoring purposes, a repeater to be so looped is selected by co-ordinate selection techniques using a signal over an auxiliary conductor pair for unit selection and a signal over the appropriate line to select the individual repeater at that unit. The figure shows a single repeater 11 connected to a line 1, the signalling conductors PR and QY, a repeater unit selector WA and a repeater selector T. The repeater unit selects are each as shown in the broken line rectangle and include a relay 19 with contacts r and s normally in the position shown and a polarized relay 20 which depending on the polarity applied between conductors sets its contacts t and u in one or other of their changeover positions and leaves them in this state when de-energized. The contact positions shown correspond to a path looped condition in which positive potential has just been applied on conductor PR and negative potential on conductor QY. Relays 19 and 20 operate in turn changing over the state of all contacts to obtain a stable state with relays 19 and 20 enabled over a path including contacts r and t. While relay 19 is enabled a set of contacts a 1  to a 4  individually associated with the repeaters of that unit are closed. In the repeater selector T individual to the selected repeater a detector 15 responds to interrupton of a selection signal received over its repeater and via an inverter 16 enables a relay 17. A relay 18 associated with the selected repeater is enabled over contacts p and a 1 , a 2 , a 3  or a 4  and closes contacts a 1  to loop the two halves 11a and 11b of the repeater 11 via a loop length simulator 10. Relay 18 also closes self holding contacts 9. To break the loop the polarity of the lines PR and QY is reversed. Maintaining the original polarity but interrupting it releases relay 19 after relays 19 and 20 have operated establishing a direct path between P and R via contacts r and t, the loop between P and Q being broken. Thus the next repeater unit selector is now in a position to respond. Thus by a number of interruptions of the polarity followed by a double reverse of the polarity selects a particular unit selector. The relays 17 and 18 may be replaced by electronic equivalents.
