Title: Anthraquinone dyestuffs and process for their manufacture
IPC: C09B1/34
Filed: 1934-06-19
Abstract: Water soluble diphenyl- or triphenyl-methane derivatives derived from anthraquinone dyes are prepared by treating sulphonated phenylaminoanthraquinones containing a free 4<1>-position in the phenyl nucleus with aldehydes in a neutral or acid medium, with the exception of bisulphites and of acids such as concentrated formic acid, which act as reducing agents; or anthraquinone derivatives of the general formula <FORM:0441845/IV/1> wherein A stands for a substituted or unsubstituted anthraquinone nucleus, R for hydrogen, alkyl or phenyl nucleus and X for hydrogen or a substituent other than a sulpho group, are subjected to a sulphonation operation.  As media for the reaction water, sulphuric acid, hydrochloric acid, acetic acid may be used and instead of aldehydes there may be used compounds yielding the same under the reaction conditions; reaction is preferably effected at 30--100 DEG  C.  In examples: (1) 1-amino-2-sulpho-4-phenylaminoanthraquinone is treated with benzaldehyde in 70 per cent sulphuric acid on a water bath (dyes greenish-blue on wool): (2) 1 - amino - 2 - sulpho - 4 - phenylaminoanthraquinone is treated with paraformaldehyde in 60 per cent sulphuric acid (greenish blue): (3) 1 - amino - 2 - sulpho - 4 - (3<1> - chlorphenyl-)-aminoanthraquinone is treated with formaldehyde in acetic acid on a water bath (blue): reference is also made to 1-amino-2-sulpho-4-(2<1> - methoxy -) - or - (3<1> - methyl -) - phenylaminoanthraquinone as starting materials.  A sample has been furnished under Sect. 2(5) of a dyestuff prepared by treating 1-phenylaminoanthraquinone with paraformaldehyde in 80 per cent sulphuric acid at 60 DEG  C. and sulphonating.  Specifications 22128/01, [Class 2], 244,462, 282,853, and 295,257, [all in Class 2 (iii)], are also referred to.

Title: Punching apparatus for producing patterns of punched holes in sheet-like material
IPC: B26F1/04
Filed: 1971-06-02
Abstract: 1307805 Selective punching apparatus K TSUKIHASHI 2 June 1971 [3 June 1970] 18544/71 Heading B4B [Also in Division B3] A punching device for producing patterns of holes in sheet material comprises a number of individual punches 12a 1 -12a n  adapted to be actuated by a ram 8 when a selected interposer 11a 1 -11a n  is moved by its particular solenoid 11b 1 -11b n  between the ram and the selected punch, feed rollers 17 driven by a stepping motor 18, theinterposer and the feed rollers being controlled by light pulses produced by the combination of holes a 1 -a n , b 1 -b n  in a disc 3 and light detectors 20, 21, 22 whereby the material is fed past the punches at a greater speed when there are no holes to be punched in the material than when there are holes to be punched. The ram 8 is connected via a link 7 and connecting rod 6 to a crank-shaft 2, Fig. 1, which is rotated by a motor 1. The material 14 to be punched is incrementally fed by the feed rolls 17 driven by the stepping motor 18. The operation of the punching device is controlled by various electronic circuits energized through the perforated disc 3 mounted on the crank-shaft and co-operating with a light source 19 and photo-electric transducers 20, 21, 22. The disc is provided with two rows of holes a 1 -a n  and b 1 -b n , and a single hole c, Fig. 3, the two rows of holes co-operating with the transducer 20, 21 respectively and the single hole with the transducer 22. The information representing holes to be punched is fed into a means 23 which is connected to an interposer driving circuit 26 connected to solenoids 11b 1 -11b n . Upon rotation of the crank-shaft, the disc rotates so that when light passes through the hole C and impinges on the transducer 22, the circuit 26 is energized and the selected interposers for a particular incremental movement of the material, are moved into alignment with the punches. Towards the end of the downward stroke of the ram 8, the holes are punched, the feed of the material being stopped during this operation. The motor 18 for the feed rollers 17 is energized during part of the downward and return strokes of the ram 8 and its speed is governed by whether or not holes are to be punched in a particular row. If holes are to be punched, light pulses passing from the source 19 through the row of holes b 1 -b n  activates the transducer 21 which through circuits 24, 25, Fig. 1, causes the motor to rotate slowly prior to the punching stroke. If holes are not to be punched, i.e. spaces are required between rows of punched information, then light pulses derived from the rows of holes a 1 -a n  and impinging on the transducer 20 causes the motor to rotate at a fast speed thereby feeding the material through the device at a higher rate thus saving time in the overall punching operation. If desired, more than two speed ranges can be used by providing a corresponding number of rows of holes in the disc.

Title: Misconvergence compensation for single-gun, plural-beam type colour tv picture tube
IPC: H01J31/20
Filed: 1969-04-14
Abstract: 1,241,111. Colour television tubes. SONY CORP. 14 April, 1969 [14 April, 1968], No. 18980/69. Heading H1D. In a colour television tube of the type wherein a plurality of beams pass through the centre of a common focusing lens and emerge along divergent paths and are subsequently converged on a shadow mask or the like by electrostatic deflecting means, the latter are adapted to converge the beams even if they are not in the designed positions due to manufacturing errors. In Fig. 11, there are three co-planar beams B B , B G  and B R  which should lie along the x axis but in fact lie along the line a. The convergence plates P<SP>1</SP> and Q<SP>1</SP> are coaxial cylinder segments centred on O 1 , and P<SP>11</SP> and Q<SP>11</SP> are similarly centred on O 2  so that each convergence field produces a force which has a component along the y axis, unlike the known planar electrode system (Fig. 3, not shown). The cylinder segments may all be coaxial (Fig. 10, not shown), or the system may comprise two coaxial cylinders (Figs. 6-9, not shown). The latter arrangment is also suitable when the three electron beams are in delta formation.
Patent GB-189928-A (GB)
Abstract: 189,928. Gledhill, A. H. Oct. 8, 1921. Ink-ribbon mechanism. - In a workmen's time recorder in which the printing of irregular entries in a different colour and out of line with regular entries is effected, the day wheel has two rows of letters arranged in staggered relation to one another and the two-colour ribbon is controlled to move to one or other of its printing positions by a member or intercepting block which is caused to occupy an operative or inoperative position by means of mechanism controlled by tappets on one of the clockwheels and by the main operating lever. The ribbon carrier a is mounted in a pivoted frame a<1> to which is attached a bar a<3> that is cranked to engage the under side of a worm g slidably mounted on a shaft g<1> communicating with the clockwork and which is rotated thereby to actuate a worm-wheel g<2> fixed to the day wheel G. The day wheel G has two rows of dayletters as shown in Fig. 5, one row of which is effective during normal periods the other being moved to printing position at irregular periods that is when the worm g is raised to rotate the day wheel G on the change over of the ink-ribbon. The position of the ink ribbon is controlled by two levers c, d which co-operate with tappets C. D on the clock work wheel B. The lever c has a projection c<2> which can be engaged by either tappet and suspended from said lever is a catch d<2> that is adapted to engage a pin a<4> on a lever a<5> having a block a' normally serving as a stop to prevent movement of a spring controlled lever a<7> connected by a slotted link a'‹ to the ink-ribbon frame a'. The lever d is pivoted to the lever c and makes a knuckle joint with the catch d. When a regular entry is made, the tappet D, Fig. 8, depresses the lever d to free the catch d<2> so that the block a<6> occupies its operative position. When a tappet C for an irregular entry becomes operative it depresses the lever c causing the catch d<2> to engage the pin a<4> so that on the release of the projection c<2> from the tappet C the return of the lever c will move the block a<6> to an inoperative position. Depression of the operating lever E thereupon releases an arm on the shaft carrying the lever a<7> which under the action of its spring a<9> is rocked and through the link a<10> raises the ink-ribbon frame a<1> to its other position. The frame a<1> is retained in its raised position during the operation by a latch a<12> adapted to engage a projection a<13> on the frame, the release being effected at the end of the operation by the bell hammer engaging a lateral projection a<14> on the latch arm.

[Also in Group XVI] Mechanism for feeding continuous flexible material to a machine, especially wire or metal strip from a coil to a wiring or banding machine or a press, comprises a reservoir 18 for accommodating slack material waiting to be fed to the machine, the reservoir being movable by the fluctuating weight of slack, a roller 10 for feeding material to the reservoir and bearing means, such as a roller 14, for frictionally engaging the material with the feed roller, and means for causing a disengaging movement of the bearing means to render the feed roller 10 inoperative due to an accumulation of weight in the reservoir and is characterized by a mechanical connection between the reservoir and bearing means, whereby movement of the reservoir is communicated to the bearing means directly. As shown, the roller 10 is secured to a driving shaft 11 driven by belt pulleys 13, thereon. The roller 14 is rotatably mounted between levers 15 carried on a shaft 16 supported by knife edges 17 on pedestals 12. The levers 15 carry the reservoir 18 which is counterbalanced by a weight 20 slidable along an arm 19. In operation, an accumulation of strip in the reservoir causes the reservoir 18 to move downwardly, against the action of the counterweight 20, to rock the roller 14 away from the roller 10, thereby stopping the feed of strip into the reservoir. A spring may replace the counterweight 20. Specification 837,763 is referred to.

Title: Improvements in circuit arrangements for conference telephones
IPC: H04M3/56
Filed: 1929-06-21
Abstract: 336,946. Siemens & Halske Akt.-Ges. Oct. 10, 1928, [Convention date]. Intercommunication systems.-A system comprising a main station and substations N1, N2, &c. has means by which a conference call may be established between the main station and any number of substations by connection of the latter to a common conference line, any existing connections between the called substations being released. The main station is provided with a loud-speaker 1 normally in circuit, the ordinary instruments being connected up by relay A on lifting of the switch-hook HU. A pair of wires 11, 12 lead to each substation, one for calling the substation by means of a key 15 and the other for calling the main station by means of a key 25. Alternatively a rotary switch may be employed in place of keys. When a key 15 is operated, relay B energizes in parallel with an alarm 23 and connects the receiver to the conference line. Lifting of the switch-hook H then connects up the transmitter, disconnects the alarm 23 and operates a reply signal over wire 12. If the substation is engaged in a call with another substation, the calling signal is transmitted induotively through relay B by the opening of contact b4 to alarm 30 at each substation, and the connection is released at contact b3. A contact 16 associated with each key 15 serves to operate a visible signal 18, 19 at each substation and at any other desired point.
