Title: The manufacture of indigoid dyestuffs of the anthraquinone series
IPC: C09B7/00
Filed: 1930-08-20
Abstract: Thioindigo dyestuffs of the anthraquinone series are manufactured from anthraquinone-1 : 2-oxythiophene by oxidation (to produce the symmetrical thioindigo dyestuff); by condensing it with cyclic diketones or their 2-derivatives, such as isatin and naphthisatin, their 2-chlorides and unclear substitution products, with oxythionaphthenes and naphthoxythionaphthenes and the anils of the corresponding diketodihydrothionaphthenes or with 1 : 2-diones such as acenaphthenequinone; or by converting it into the anils of the corresponding diketodihydrothiophene and condensing these with compounds containing a reactive methylene group.  In examples: (1) anthraquinone-1 : 2-oxythiophene is oxidized to symmetrical anthraquinone-1 : 2-bisthioindigo by means of potassium ferricyanide in alkaline solution or by means of hydrogen peroxide or a persulphate; the product dyes cotton brownish shades; (2) anthraquinone-1 : 2-oxythiophene is condensed in monochlorobenzene solution with 5 : 7-dibromisatin-2-chloride (obtained by the action of phosphorous pentachloride on 5 : 7-dibromo-a -isatin); the product dyes cotton grey shades; (3) 9-chloro-a -naphthisatin is converted into its chloride by the action of phosphorous pentachloride and the product condensed as in (2) with anthraquinone-1 : 2-oxythiophene; the 9-chloro-a -naphthisatin may be replaced by its monobrominated derivative or by dibromo-b -naphthisatin; the products dye cotton olive-green, blueish grey and greyish green shades respectively; (4) anthraquinone-1- : 2-(2<1> : 3<1>-diketodihydro) - thiophene - 2<1> - (p - dimethylamino) - anil (obtained by the action of p-nitrosodimethylaniline on anthraquinone-1 : 2-oxythiophene) is condensed in glacial acetic acid solution with 6-ethoxyoxythionaphthene or 6-chloro-oxythionaphthene; the products dye cotton yellowish brown and reddish brown shades respectively; (5) anthraquinone-1 : 2-oxythiophene is condensed in glacial acetic acid solution with the p-dimethylamino-anils of 4 : 5-and 5 : 6-benzo-2 : 3-diketodihydrothionaphthene (obtained by the action of p-nitrosodimethylaniline on 4 : 5-and 5 : 6-benzo-3-oxythiophene); the products dye cotton brown and greenish grey shades respectively; (6) anthraquinone-1 : 2-oxythiophene is condensed in glacial acetic acid solution, with the addition of a little concentrated hydrochloric acid, with 9-chloro-a -naphthisatin; the product dyes cotton yellowish olive shades.  Specifications 286,358, [Class 2 (iii), Dyes &c.], and 349,080 are referred to.

Title: Repetitive playback means
IPC: G05B19/12
Filed: 1969-05-20
Abstract: 1,246,713. Programmed control of machines. EDOUARD DUBIED & CIE S.A. May 20, 1969 [May 21, 1968j, No.25763/69. Heading G3N. A device for repetitively playing back items of information, as for the programmed control of a machine, comprises a device for reversible step-by-step movement of a tape bearing parallel tracks bearing two categories of information one of which is read in each direction of travel. A film, for the control of a knitting machine, is reversibly transferred between storage spools, past a photo-electric reading head, by a stepping motor. The film 1, as shown is driven through sprocket holes and during movement in direction 36 the information recorded at locations 33 is selected and conversely for direction 36<SP>1</SP> the information at locations 33<SP>1</SP> is selected. The information, as punched holes or transparent circles, form parallel tracks, one for each knitting station, and two synchronization tracks formed of locations 31, 32. Circles a to z are projections on film 1 of the resistive surfaces of photo-cells 28 which deliver pulses during a stepping movement by the motor. The cell m or n is operative in dependence on the direction of travel of the film and the information read by the other cells is only transmitted when it coincides with the pulse from the operative cell m, n. The selection of information to be transmitted for effecting a control function is carried out by a logic circuit. The film movement is synchronized with the operation of the knitting machine and the reversal of the film is effected by datum marks at each end of the film. The step rest positions for the two directions of travel are staggered by half a step by means of a mechanical gear, or lost motion, or by an electrical modification of the stepping motor operation. It is stated that a magnetic tape could be employed.

Abstract: 859,137. Electrically - released switches. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. July 31, 1959, No. 26300/59. Addition to 811,367. Class 38 (5). A relay which is retained set, after electromagnetic actuation, by permanent magnetism and which has a permanent magnet and release coil as parts of a magnetic circuit separate from that of the operating coil as in the parent Specification, has a magnetic shunt, including an air gap, across the permanent magnet. As shown, a pivoted armature 16 is attracted, against the bias of a spring 19, to poles 12, 13 on energization of a coil 15, to actuate contacts (not shown) coupled to a lug 20. The armature approaches but does not engage the ends of cores 26, 27 which carry release coils 28, 29 and are secured to polepieces 23, 24 and a magnet 21. When the armature is in the attracted position the gap between it and the core ends is less than the gap 25 between the polepieces 23, 24 which normally forms a shunt path for the permanent flux. The cores 26, 27 release coils 28, 29, polepieces 23, 24, magnet 21 and a magnetic back-strap 22 are carried on a non-magnetic bracket 32 attached to the polepiece 12, this support means being sufficient since the core ends are not " hammered " by armature impact.

Title: Automatic immersion apparatus
IPC: G01N1/31
Filed: 1956-08-28
Abstract: 801,474. Rotary conveyers. TECHNICON INTERNATIONAL, Ltd. Aug. 28, 1956 [Sept. 14, 1955], No. 26318/56. Class 78 (1). [Also in Group XX] Automatic immersion apparatus particularly of the kind described in Specifications 570,430 and 697,214 [both in Group XX], for treating histologic tissue preparatory to microscopic examination, is provided with manually-actuated auxiliary control means operable by a momentary actuation thereof to cause a single operation of the conveyer 20, Fig. 1, for moving the holder 18 to a raised position independently of the time-control device 82. The motor 90, Fig. 3, which actuates the apparatus, when under automatic control is controlled primarily by microswitches 100, 102. The auxiliary control means comprises a relay 104 in combination with a microswitch 106 and a push-button switch 108. The control circuit is shown as it is when the holder 18 is immersed in receptacles 14 for periods of time determined by the control device 82. In this condition the relay 104 is de-energized and released with its front contacts a and b open and its back contact b closed. If the push-button 108 is depressed, the closing of the contact b establishes an auxiliary energizing circuit for the motor 90 and the conveyer 20 commences to rise. The closing of the contact a establishes an energizing circuit for the relay 104 and its back contact b opens and its front contacts a and b close. The opening of the back contact b breaks the automatically controlled energizing circuits for the motor 90 and the closing of the front contacts a, b establishes a holding circuit for the relay. If the push-button 108 is depressed again to close the contacts a, b, the energizing circuit for the motor 90 becomes re-established and the conveyer commences to rotate. At the same time the motor rotates the cam 154 to cause the contact 162-164 to reclose, thus establishing an auxiliary energizing circuit for the motor. The push-button 108 is now released and the conveyer completes its rotation and moves downward to its lowest position. Meanwhile the cam 124 has turned to open the contact 128-130 and to close the contact 128-134. The holding circuit for the relay is thus broken and its front contacts a, b are opened and its back contact b closed. Since the contact 116-118 of the microswitch 100 is closed, an automatically-controlled energizing circuit for the motor 90 becomes established.
