Abstract: 1438321 Thermoplastics pipe A G PETZETAKIS 21 June 1973 [21 June 1972] 29551/73 Heading F2P A large bore pipe 1, e.g. for drains, consists of a hollow element 2 of thermoplastic synthetic material, e.g. polyethylene or polyvinyl chloride, wound into a helical coil, with the windings 5 touching each other at side surface 8 of the hollow element and being welded at each other by means of a butt weld 6, the free walls 7 of the hollow element forming the inner and outer surfaces of the pipe. The hollow element 2 has a substantially rectangular outside cross section 3 and a rounded inner cross-section 4, e.g. of circular, elliptical or rounded rectangular shape. The pipe is made by extruding the hollow element 2 and winding the extruded element 2 into a helical coil, the windings 5 being welded together by the residual heat from the extrusion process. The construction of the pipe 1 allows it to bend slightly, the free walls 7 of the pipe being defined during bending to avoid damage to the butt weld 6. The free walls 7 are also capable of creep, so that the stresses produced by bending are relaxed after a time. The element 2 may have a covering of a different material (not shown) which covering forms the inner and/or outer surface of the pipe.

Abstract: 1277896 Variable-speed gear L H WIDDERSHOVEN 11 June 1969 [13 June 1968] 29566/69 Heading F2D A steplessly variable planetary gear comprises a planet-carrier 2 fast on an input shaft 1, a toothed sun 10 fast on an aligned output shaft 11, and meshing four planetary idlers 9 meshing further planets 8, the four spindles 6 of which carry overhung grooved planet pulleys 7 tracked by belts (or chains) which assume a polygonal shape and constitute a deformable stationary ring gear, the effective diameter of which can be varied to vary the speed ratio by turning the pulley spindles 6 bodily about the spindles 3 of the planetary idlers 9, the pulley   spindles 6 being carried in discs 4 secured to the idler spindles 3 and connected together for movement in unison by chains 5. The belts tracking the planet pulleys 7 are not endless but are constituted by groups of separate belts A . . . H anchored at their ends to tension and end pulleys R 1 ...R 4 ; T 1 ...T 4  and passing round some of the planet pulleys 7. Thus the first belt A is attached at one end 17 to a tension pulley R 2 , passes round tension pulley R 4  and three of the planet pulleys 7, to be anchored at its other end 16 to an end pulley T 1 . The remaining belts B...H are similarly tracked and anchored to respective pulleys as shown. The tension pulleys R 1  &c. are arranged in two diametrically opposite groups R 1 ...R 4 , R 1 <SP>1</SP>...R 4 <SP>1</SP> and having a fixed anchorage, one pair of each group being supported on links. The end pulleys, similarly grouped as T 1  ... T 4 , T 1 <SP>1</SP> ... T 4 <SP>1</SP>, are directly carried on a frame 15 which is pivoted about the shaft axis M to cause inward or outward movement of the planet pulleys 7 thus varying the speed ratio. Belt tension during adjustment is maintained by groups of further tensioning pulleys V 1  ... V 4 , V 1 <SP>1</SP> ... V 4 <SP>1</SP>, some mounted on fixed pivots, others on links carried by fixed pivots, these pulleys being tracked by separate pairs of belts attached at their ends e.g. 27, to pairs of end pulleys T 1  &c. Thus when the ratio-adjusting frame 15 is turned clockwise (arrow S), the end pulleys T1 &c. are caused to turn anticlockwise and the belts A ... H turn the pulleys 7 anticlockwise to produce inward movement of the planetspindles 6 and hence reduce output speed. Equalizer bars P, P<SP>1</SP>; W, W<SP>1</SP>, connect opposite groups of pulleys. The angular disposition of the various pulleys is important to the attainment of equalized adjustment. The angle included between the gear axis M and the points of tangency, e.g. 19, 20, of a belt, A, on its contacting tension or end pulleys R or T is 45 degrees, the next adjacent belt, B, half overlapping this angle, whilst the group R 1 <SP>1</SP> &c. leads the opposite group R 1  &c. by a quarter of this angle.

Title: Process for the manufacture of azo dyestuffs
IPC: C09B29/32
Filed: 1930-10-03
Abstract: Azo dyes.--Leuco sulphuric acid esters of azo dyes, which yield green shades when treated with acid oxidizing agents in substance or on the fibre, are made by coupling diazotized leuco sulphuric esters of blue to violet indole naphthalene-, indole anthracene-, or indole thionaphthene-indigos, containing a free amino group in the Bz-nucleus of the indole or thionaphthene residues, with acyloacetic arylides or pyrazolones.  The diazotization may be effected in the presence of a weak organic acid, e.g. acetic acid. The leuco sulphuric esters used as parent materials may be made from the corresponding indigoid vat dyes containing amino or nitro groups; in the former case the amino groups are acylated before esterification, the acyl group being subsequently split off, while in the latter case the nitro groups are reduced after esterification.  In examples (1) the leuco sulphuric ester obtained by the process of Specification 360,958 from the dyestuff made by coupling 5-nitroisatin-a -chloride with 1 : 4-chlornaphthol is diazotized and coupled with acetoacetic anilide; a yellow dyestuff, soluble in water, is obtained, which yields an insoluble green dyestuff when treated with sodium nitrite in aqueous solution, (2) the leuco ester salt of 5-aminoindol-a -anthracene indigo is diazotized and coupled with 1-phenyl-3-methyl-5-pyrazolone, (3) the leuco ester salt of 4 : 7-dimethyl-5-aminoindol-4<1>-methoxynaphthalene-indigo (made by esterifying the condensation product from 4 : 7-dimethyl-5-nitroisatin-a -chloride and 1-methoxy-4-naphthol and reducing the nitro group) is diazotized and coupled with acetoacetic-o-anisidide, (4) the leuco ester salt made by esterifying the condensation product of 5-nitro-6-chlor-7-methylisatin chloride with 1 : 4-chlornaphthol and reducing the nitro group is diazotized and coupled with acetoacetic-o-chloranilide, and (5) the leuco ester salt obtained from 4-methyl-5-chlor-7-methoxyindol-5<1>-amino-thionaphtheneindigo is diazotized and coupled with acetoacetic-o-anisidide. Specifications 336,506 and 336,507, [both in Class 2 (iii), Dyes &c.], are referred to.  Isatins.--4 : 7-Dimethyl-5-nitroisatin is obtained by nitrating 4 : 7-dimethylisatin.  5-Nitro-6-chlor-7-methylisatin is made by nitrating 6-chlor-7-methylisatin in sulphuric acid. 5-Nitro-oxythionaphthene is made from 5-nitro-2-chlorbenzoic acid.

Title: Printing method and apparatus
Inventor: HUEBNER WILLIAM CARL
IPC: B41M1/42
Filed: 1953-10-27
Abstract: 741,259. Printing-machines. HUEBNER CO. Oct. 27, 1953, No. 29649/53. Class 100 (2) In a printing-machine of the kind in which an inked image, carried on a printing cylinder 46 is transferred to print receiving material M in a printing zone by means of a high potential, unidirectional cyclically pulsating electrostatic field of force, the film of ink on the printing cylinder and the material M are charged, before entry into the printing zone, with unidirectional electrostatic charges of opposite polarity to assist the field of force in the printing zone to effect the transfer of the ink. The printing cylinder 46 is rotatably mounted and bears a relief, intaglio or planographic image inked, e.g. by rollers 48, 49. An electrode blade 47 mounted in a stationary insulating sleeve 12 inside cylinder 46 co-operates with a similar electrode 51 mounted inside a supporting cylinder 50 to provide the field of force in the printing zone. The material M for printing passes between cylinders 46, 50 but is subjected to substantially no pressure. A source of high-voltage direct-current 56, which may consist of a transformer and rectifier valves, has output wires 60, 61 and 62, 63 connected to reversing switches 70 and 90. A wire 76 from electrode 51 has a brush 75 bearing on a rotary switch or commutator 74 mounted on the shaft of a small motor 83. A brush 73 bearing on the other side of the switch 74 is connected to one pole of switch 70. The other pole of this switch is connected through an ammeter A (or its shorting switch 89) to the electrode 47. To stabilize the voltage applied between the electrodes 47, 51 condensers 78, 79 and resistances 80, 81 are connected between wires 71, 72. A wire 82 connects the centre points of the condensers and resistances. The applied voltage may be indicated on a voltmeter V. The speed of the motor 83 may be varied by a rheostat 86 to vary the number of pulses per second between the electrodes. Charging devices 52, 53 are applied to the surface of the printing cylinder and to the web. The device 52 is curved to mate with the surface of the cylinder and has a series of discharge teeth 54. It is connected by wires 104, 92 to one pole of switch 90. The other pole of switch 90 is connected through a rotary switch 94, driven by motor 95, to the charging device 53 applied to the material M. A similar stabilizing circuit is provided for the voltage between the devices 52, 53. By this means pulsating unidirectional potentials may be applied between the electrodes 47 and 51 and between the charging devices 52 and 53. The number of pulses per second may be varied by rheostats 86, 96 and the potentials may be varied by controls 64, 65 on the source 56. The reversing switches 70 and 90 may be ganged together for simultaneous operation. A steady potential may be applied between the devices 52, 53 by de-energizing motor 95 and turning switch 94 to the connecting position. Reference has been directed by the Comptroller to Specification 613,163.

Title: Improvements relating to acetylene generators
IPC: C10H15/06
Filed: 1930-10-04
Abstract: <PICT:0370427/IV/1> <PICT:0370427/IV/2> In an acetylene generator in which carbide is dropped into the water in a generating chamber 6 through an elongated tube 13 controlled at its upper end by a valve, the tube 13 is funnel-shaped at its upper end and is adapted to deliver the carbide at a point above but adjacent to the surface of the water in the generating chamber.  The generating chamber may be arranged in a vessel 1, and means may be provided for effecting a circuitous flow of water from the inside to the outside of the chamber 6.  As shown, the chamber 6 has two diametrically opposed holes 10 at the base, and rests on a collar 2 extending upwardly into the chamber and having diametrically opposed holes 5 arranged at a considerable angular distance from the holes 10.  The opening 17, Fig. 2, of the carbide receptacle 15 is adapted to be closed by a valve 18 carried on a rod 19 attached to a diaphragm 22 responsive to the pressure of the gas.  Closure of the opening 17 can also be effected from outside by means of a lever 24, which can be raised so as to cause the cam end 24a to raise the diaphragm 22.  Normally, however, a spring 25 depresses the diaphragm 22 and tends to keep the delivery valve open.  The tube 13 is provided with a skirt 13c, which prevents condensed moisture that trickles down the tube from reaching the mouth of the tube. The receptacle 15 is charged through an opening 48.  Gas is delivered from the chamber 6 through a tube 40 to a combined water seal and purifier comprising a three-compartment vessel 32 having a layer of coke arranged between a plate 36 and a perforated plate 34.  The gas inlet tube 44 reaches nearly to the bottom of the bottom compartment, which contains the sealing water, the gas passing through the plate 34 and the coke layer to the outlet 47. A tube 45 behind the tube 44 extends into the sealing water to a point above the end of the tube 44, and opens into the top space 37 of the vessel 32, in which a vent 37a is provided.  If a back-flow occurs, the tube 45 is unsealed first, and the gas escapes through the vent.  The sealing water is introduced through the vent 37a and a tube 46.  In the operation of the generator, excessive pressure of gas acts on the diaphragm 22 to close the opening 17, and also depresses the water in the collar 2, the circuitous path provided between the vessel 1 and the interior of the collar 2 helping to maintain the water at a uniform temperature.  When the pressure falls, the water in the chamber 6 rises, and a further amount of carbide is automatically delivered. To shut off the carbide feed in the event of accident, such as rupture of the diaphragm 22 or overturning of the generator, a sliding valve 18b is provided on the rod 19.

The bolt 27 is withdrawable by means of a crank 31 and link 29 operated by a thumb-turn 32 or by means of a cam 35 operated by a pin-tumbler cylinder lock 39. The bolt housing 25 is supported at one end by a screw 51 and spring 50 so that excessive force on the door 7 in the upward direction (as shown in Fig. 1) causes the bolt housing 25 to pivot about a face plate 18, moving the fulcrum 64 of the contact-closing lever 61 (of insulating material) so as to close contacts 66, 69. The bolt 27 has a narrow plate 56 let into a groove and supported by rivets carrying the springs 57 so that if excessive force is applied to the door 7 in the downward direction (as shown in Fig. 1) the bolt 27 and housing 25 will be pivoted about screw 50 so as to cause lever 61 to close alarm contacts 66, 69. Fig. 3 shows the form of contacts 66, 69 which, when operated, remain closed until the end of lever 61 is reset to its normal position in a slot 62 in the end wall 17. The alarm may be a speaker 60 contained in the lock casing.
