Title: Magnetic or electromagnetic operated ratchet device particularly used as an irreversible device for small sychronous motors of the so-called reaction type and the like
IPC: H02K7/118
Filed: 1954-08-18
Abstract: 756,807. Devices ensuring uni-directional rotation. OFFICINE GALILEO SOC. PER AZIONI. Aug. 18, 1954 [Aug. 26, 1953], No, 24024/54. Class 80(4) A ratchet device for ensuring uni-directional rotation of a rotary member, such as the rotor of a synchronous electric motor, comprises a pivoted pawl 3 co-operating with ratchet teeth 5 on the rotary member 1 which is kept in engagement by magnetic attraction between a soft iron tailpiece 6 on the pawl and a permanent magnet 7. Alternatively the tailpiece 6 may be arranged adjacent and acted upon by the magnetic poles of the stator of the motor. Also the tailpiece 6 may be the permanent magnet and the member 7 may be of soft iron.

Title: Card-arresting device for use in time-recording apparatus
IPC: G06K13/063
Filed: 1961-07-03
Abstract: 912,778. Time-recording apparatus. TELEFONAKTIEBOLAGET L. M. ERICSSON. July 3, 1961 [July 1, 1960], No. 24029/61. Class 106 (4). In a card-arresting device for use in time-recording apparatus, the position of punchings to be applied to a card 20 is determined by a deformation of the card which deformation is used to actuate a testing device 2 when the card is inserted in the apparatus, and testing device 2 is arranged to be so actuated by a deformation of the card that it is moved together with the card and substantially parallel thereto and by this movement causes the operation of a locking arrangement which acts upon the card. Testing device 2, having a test member 1 consisting of a number of thin resilient ribs or of a leaf-spring, is pivotally mounted at 3 on a locking lever 4 which is mounted on a pivot 5 fixed to a supporting frame (not shown). A spring 8 urges member 1 against card 20, and lever 4 is normally kept out of engagement with card 20 by the force exerted by contact-spring 15 through a plunger 16 and a lever 17 pivoted to the supporting frame. When card 20 is inserted and a hole in or other deformation of the card is engaged by the free end of member 1, device 2 is moved downwardly with the card, thereby rotating lever 4 clockwise so that a locking tooth 18 on lever 4 engages the card, which is thus squeezed tightly between tooth 18 and a fixed member 22. The movement of lever 4 moves spring 15 into contact with spring 14, thereby closing a circuit to bring about punching of the card.

Title: The manufacture of azodyestuffs and dyeing and printing preparations
Filed: 1934-08-22
Abstract: Azo dyes; lakes; dye preparations; azo dyes, forming upon the material; printing.--Azo dyes are manufactured in substance or on a substratum, particularly vegetable fibres, by splitting up by the action of an acid medium a triazene compound obtained by condensing cyanamide, cyanamide-carboxylic acid or a salt thereof with a diazo compound of a base suitable for preparing water-insoluble azo dyes, in the presence of a coupling component free from solubilizing groups.  Preparations for dyeing and printing purposes comprise a mixture of the said triazene compounds and coupling components, if desired with the addition of wetting or dispersing agents.  The dyeing may be developed by treatment in an acid medium, or in some cases by merely hanging in the air.  In examples: (1) cotton tissue is printed with an aqueous mixture of the condensation product from diazotized 5-nitro-2-amino-1-methoxybenzene and sodium cyanamide, 2 : 3-hydroxynaphthoic acid a -naphthylamide, highly sulphonated castor oil, caustic soda and starch tragacanth thickener, and a full Bordeaux is developed by exposure to superheated steam containing formic and acetic acid vapours or by treatment in an aqueous formic or acetic acid solution; (2) a similar printing colour containing the condensation product from diazotized 5-nitro-2-amino-1 methylbenzene and sodium cyanamide, and 2 : 3-hydroxynaphthoic acid o-toluidide yields a full reddish-Bordeaux; (3) a similar printing colour containing the condensation product from diazotized 4-chloro-2-anisidine and sodium cyanamide, and 2 : 3-hydroxynaphthoic acid o-anisidide yields a full clear red; (4) a similar printing colour containing the condensation product from diazotized 2-nitro-4-chloraniline and sodium cyanamide, and 2 : 3-hydroxynaphthoic acid anilide yields a full yellowish-red; there may similarly be employed the condensation products from sodium cyanamide and diazotized 4-nitro-2-toluidine, 2-nitro-4-toluidine, 4-chloro-2-toluidine, 2 : 5-dichloraniline, 5 - benzoylamino - 2 - amino - 1 : 4-diethoxybenzene, 4-amino-4<1>-nitro-3-methoxy-6-methylazobenzene, 2-aminocarbazole or 1-aminoanthraquinone; (5) a similar printing colour containing the condensation product from diazotized 5-nitro-2-amino-1-methoxy-benzene and the sodium salt of cyanamide-carboxylic acid, and 2 : 3-hydroxynaphthoic acid a -naphthylamide yields a full Bordeaux.  The Specification as open to inspection under Sect. 91 comprises also the manufacture of the triazene compounds employed above. Additional examples describe the manufacture of the triazene compounds employed in (1), (2) and (5) above, and also of the condensation products of sodium cyanamide with diazotized 2 : 5 - dichloraniline or 4 - amino - 4<1> - nitro - 3-methoxy - 6 - methylazobenzene, and of the sodium salt of cyanamide-carboxylic acid with diazotized 5 - nitro - 2 - amino - 1 - methylbenzene.

Title: Improvements in or relating to electron beam coding tubes and signal encoding systems using such coding tubes

Abstract: 679,730. Cathode-ray tubes. WESTERN ELECTRIC CO., Inc. Sept. 23, 1949 [Sept. 30, 1948], No. 24490/49. Class 39 (i). [Also in Group XL (c)] In a pulse code modulation system in which a flat beam 31, Fig. 3, is deflected by input signal samples over an apertured coding plate 36, and the output group of pulses appear simultaneously on target electrodes 41 ... 47, an auxiliary pilot beam 30, also flat, co-operates with auxiliary apertures 37 and auxiliary target 40 connected by a feed-back path 71 to deflecting plates 32, 34 to align the main beam relatively to a row of coding apertures, and means such as grids 23, 33 are provided for suppressing the main and pilot beams independently of one another. There are seven vertical columns of coding apertures, the horizontal rows being arranged in accordance with the binary system. -The electron gun structure is a modification of that described in Specification 553,943 and comprises linear directly or indirectly heated cathode 22, Fig. 1, grids 23, 33, and a U-shaped shield 24 with plates 25 attached to the legs of the U. The beams 30, 31 are subjected to (a) electrodes 28, 29 for focusing, and (b) electrodes 1, 2, 3 for shaping the beams and maintaining their spacing. A shield may be interposed between grids 23, 33. In operation, a signal sample is applied to deflecting plates 32, 34 and the pilot beam is switched in while the main beam is blanked; this enables the feed-back circuit to function to centre the pilot beam on an aperture 37. The main beam is then switched in and is then automatically in alignment with the correct row of coding apertures. The main beam is kept on just for the duration of a code pulse. The code pulses may be simultaneously transmitted over individual transmission channels or applied to a distributer to arrange them in sequential order for transmission over a single channel. In the latter arrangement delay circuits D<SP>1</SP> ... D' giving varying delays are included in the output leads, as shown in Fig. 3, and the combined group of pulses is then passed to a common amplifier 90, which may also include shaping circuits. In a modified construction, Fig. 2 (not shown), the single main beam is replaced by a plurality of parallel beams with separate cathodes and focusing arrangements, so that the beams can be controlled separately to equalize their intensities. Specifications 663,837 and 679,725 also are referred to. The Specification as open to inspection under Sect. 91, states that the main beam may be a " point " beam instead of flat, in which case it is swept over the selected row of code apertures. This subject-matter does not appear in the Specification as accepted.
