Title: Vat dyestuffs and a process of preparing the same
IPC: C09B3/36
Filed: 1930-10-31
Abstract: Dibenzanthrone dyes are made by etherifying Bz 2 : Bz2<1>-dihydroxy- or Bz2-hydroxy-Bz2<1> alkoxy-dibenzanthrones with an alkylating agent of the general formula Y-CH2-CH2-X-CH2-CH2-Z, where X is an oxygen atom or imino group, and where Y and Z both represent strong acid residues, e.g. chlorine, bromine, sulphate or arylsulphonate, or one of them represents a strong acid residue, while the other represents an alkoxyl group.  In cases where products containing free hydroxyl groups are formed, the fastness to acid may be increased by further alkylation, e.g. by methylation.  The products dye in green shades, the dyeings being in many cases substantially yellower in shade than those from Bz2 : Bz2<1>-dimethoxydibenzanthrone.  In examples, Bz2 : Bz2<1>-dihydroxydibenzanthrone is alkylated with (1) the di-p-toluenesulphonic ester of diethyleneglycol under varying conditions; the product in one instance is methylated by treating with p-toluenesulphonic methylester; (2) with the p-toluenesulphonic esters of diethyleneglycol-mono-methyl-, mono-ethyl-, and mono-nbutyl ethers; (3) with the di-p-toluenesulphonic ester of diethanolamine, (4) with dibromethylether and (5) with dichlorethylether. Bz2-hydroxy-Bz2<1>-methoxydibenzanthrone is also specified as a starting material.  Specifications 14498/12 193,431, and 273,247, [all in Class 2 (iii), Dyes &c.], are referred to. p-Toluenesulphonic esters.--The above-mentioned p-toluenesulphonic esters are made by the action of p-toluenesulphonic chloride on the corresponding hydroxy compounds.  The Specification as open to inspection under Sect. 91 (3) (a) is not restricted to the treatment of Bz2 : Bz2<1>-derivatives, but includes the use as parent materials of hydroxy-dibenzanthrones in general, including substituted hydroxydibenzanthrones, e.g. halogenated dihydroxydibenzanthrones. It also includes the use of alkylating agents of the general formula in which X represents a sulphur atom, or in which one of the substituents Y, Z may represent the group OR, where R stands for an aryl, aralkyl or acyl group.  This subject-matter does not appear in the Specification as accepted.

Title: Process for the separation and purification of high purity acetylene
IPC: C07C7/11
Filed: 1972-07-13
Abstract: 1346033 Separation of acetylene and ethylene LUMMUS CO 13 July 1972 [15 July 1971] 32874/72 Heading C5E Acetylene is separated from a gaseous mixture of acetylene and ethylene by passing the mixture via line 1 into a contact column 2 having presaturation, absorption and stripping zones 3, 4 and 5 respectively, in counter-current with a refrigerated selective solvent, e.g. dimethyl formamide, via line 6. Absorption occurs in zone 4 and the enriched solvent then passes to zone 5 where it is partially stripped of ethylene by reboiled vapours introduced at 10 from reboiler 9. Substantially pure ethylene leaves by line 20. The enriched solvent leaves column 20 via line 21 and is cooled e.g. by 35-65‹ F. in heat exchanger 22 and then introduced into stabilizer tower 25 having absorption and stripping zones 26 and 27 respectively, wherein the remainder of the ethylene and a portion of acetylene are stripped by reboiled vapours. The stripped gaseous stream is passed upwards through zone 26 where it is contacted with refrigerated selective solvent introduced at 33 to reabsorb the acetylene. Gaseous ethylene is withdrawn at 36 and is combined with feedstock to form the feed in line 1. The acetylene rich bottoms in line 37 are stripped in column 40 with reboiled vapours and is withdrawn at 46. The partial pressure of acetylene in reboiled vapours of column 2 is monitored and the temperature of the reboiler 9 controlled in response thereto.

Filed: 1946-11-06
Abstract: 657,474. Scoop-arm loading machines. JOY MANUFACTURING CO. Nov. 6, 1946, No. 33011. Convention date, Nov. 6, 1945. [Class 78 (iii)] [Also in Group XXI] In a loading machine of the type comprising a shovel swung vertically by a shovel-raising motor, from a material-receiving position to a material discharging position, and adapted also to be swung horizontally so that the materialreceiving position may be towards one side of the machine, the member which controls the shovel-raising motor is arranged, by further movement in the same direction, to control also a centring motor, so that the shovel is centred during at least the latter portion of its upward vertical swing. The shovel 8 (Fig. 1) is mounted on arms 11 carrying rollers 12 engaging a track 13 on side-plates 14 secured to a turntable 7 on a portable base 3. The arms 11 also carry semicircular segments 15 engaging the usual spring-tensioned cables 16, 17 so that as the shovel is raised by chains (not shown) wound on drums on a shaft 20 journalled in the side-plates 14, it moves in a curved path to the broken-line position shown. The shaft 20 is rotated through chain-and-sprocket gearing from a reversible hydraulic motor on the turntable 7 under the control of a valve operated through a linkage 27, 26, 25, 24 (Fig. 7) from a lever 29. Buffers (not shown) stop the bucket at the end of its travel, projecting the material into a following mine car M and initiating the return movement under gravity. The centring means for the turn-table 7 comprises (Fig. 8) a pair of opposed hydraulic rams 40, the pistons of which are connected by links 42 to arms 43 pivoted at 44 to the base 3. The arms 44 may be swung into engagement with a roller 45 on the lower end of a pin 46 projecting vertically downwards from the turn-table 7 through an arcuate slot 47 in the top of the base 3. A vertical pin adapted to be pressed into engagement with a socket in the underside of the turntable 7 by a hydraulic ram 54 on the base 3, to lock the turn-table in its central position is normally retracted by a spring. Pressure-fluid is admitted to the cylinders 40, 40 and 54 simultaneously to centre the turn-table 7 and to lock it centrally. Admission of pressure fluid to these cylinders is controlled by a valve 65 (Fig. 7) pressed by a spring 78 to a position rendering the rams 40, 40, 54 inoperative but moved to supply fluid to the rams to centre the turn-table by a cam 77 on the shaft 27 when the lever 29 is moved to raise the shovel 8. The lever 29 is capable of being moved sufficiently to permit a digging action of the shovel 8 without affecting the centring means. Hydraulic connection between apparatus on the turntable and on the base is made through bores in the pivot of the turn-table. The wheels 5 (Fig. 1) run on tracks 6 and are driven by a hydraulic motor 10. Specification 649,101 is referred to.

Title: Improvements in transformers having ratio-control means
IPC: H01F29/06
Filed: 1946-11-08
Abstract: 634,496. Transformers. BRITISH THOMSON-HOUSTON CO., Ltd. Nov. 8, 1946, No. 33299. Convention date, Nov. 8, 1945. [Class 38 (ii)] One winding of a transformer comprises two equal voltage sections, one end of each being connected together through one winding of an auxiliary transformer, the other ends being connected through the other winding, the terminals for the connections to the winding of the main transformer being connected, one to a fixed tap on -that winding and the other to one or more adjustable contacts which move over taps on the sections. The secondary winding of a transformer 1 is divided into two parts 5, 6, the ends of which are connected to the ends of similar windings 9, 10 of another transformer 8, so that the polarities of secondaries 5, 6 oppose and of windings 9, 10 assist. The connections 4, 4 of the secondaries 5, 6 to the external circuit in supplying which they or parts of them are effectively in parallel, are made respectively to one end of secondary 5, and to contacts 11, 12 which engage tappings on secondaries 5, 6 respectively. During on-load tap changing, contacts 11, 12 are alternately at points at the same and at different voltages. This voltage difference produces circulating currents in two circuits-shown by the dotted and solid arrows respectively-which each include parts of the secondaries 5, 6 equivalent to the whole of one winding, and one of the windings 9, 10, the induction between which keeps the two circulating currents equal.' Whatever the transformation ratio of the main transformer 1, when the contacts 11, 12 are at points of unequal voltage, the two equal circulating currents are unchanged as they flow through similar paths with equal impedances which remain unchanged. A modification is described in which the two secondary windings are wound together with alternating turns along which a sliding contact moves to touch, first a turn of each winding and then a turn of one only, Fig. 1 (not shown). The invention may also be applied to auto-transformers in which the regulation is all bucking or boosting, Fig. 3 (not shown), or includes both bucking and boosting, Fig. 4 (not shown).

Title: Mechanical relay for transmitting moving impulses
IPC: F16H33/20
Filed: 1927-12-10
Abstract: 282,739. Siemens - Schuckertwerke Akt.-Ges., (Assignees of Siemens-Schuckertwerke Ges.). Dec. 24, 1926, [Convention date]. thermostats. - Consists of a mechanical relay for use with control devices, more particularly for steam boilers, of the kind in which the controlling force is exercised at prescribed time intervals only and comprising a reciprocating member the movement of which is transmitted to a second or driven member to an extent which is variable in accordance with the indication of the thermopile, C O2 meter, pressure gauge or other sensitive instrument employed, and consists of means for fixing the driven member in its adjusted position during a part of the regulating process. Fig. 1 shows the main arrangement and Fig. 3 a preliminary relay which is used where the strength of the sensitive member is very small. The needle 1, Fig. 1, has a range of movement between bars 3, 4, slidable parallel to themselves on guides 5, 6. The bar 3 is moved by means of a reciprocating rod 12 and a cam face 23 and, according to the position of the needle 1 with respect to the sloping face 25 of the bar 4, compresses more or less a chamber 20 containing the pressure fluid by which the relay piston of the setting device is operated. The bar 4 is locked during return of the bar 3, to leave the needle 1 free to take up a new position, by means of a locking device comprising a clamp 26 carrying, by means of a clamping coupling 30 or the like, an arm 28. On the rod 12 moving to the right a pin 27 on it engages the arm 28 and releases the clamp 26, which is therefore pushed down with the bar 4. On the reverse movement of the rod 12 the clamp 26 becomes locked in its lower position. The rod 12 is'reciprocated at regular intervals by means of a motor-driven piston and hydraulic transmission. In the preliminary relay, Fig. 3, the same principle is employed, but the needle 39 of the sensitive instrument moves over a fixed bar 38 and only part of the predetermined downward movement due to the cam member (here a rotating cam 31) is imparted to the coacting bar 35, the remainder of such movement being taken up by a spring. 34 (to an extent depending on the position of the needle with respect to the sloping face 40 of the bar 35). The bar 35 is connected by linkage 41, 42, 43 to the needle 1 of Fig. 1.
