Title: Improvements in or relating to the treatment of vegetable fibres and vegetable fibrewaste to separate fibres from short straw, shives and the like
IPC: D01B5/00
Filed: 1945-10-15
Abstract: 607,705. Preparing fibres for spinning. VANHAUWAERT, A., VANHAUWAERT, E., and VANHAUWAERT, A. Oct. 15, 1945, No. 26904. Convention date, July 12. [Class 120(i)] Fibres are separated from straw and the like, particularly in the treatment of flaxtow, by a teasing action in which a layer of the material on an openwork and preferably inclined support is subjected to a movement obtained by displacement of the support, and also to the action of combs which enter the material from above and oscillate rapidly in a direction parallel to the direction of advance of the material, the combs being operated in a yieldable manner so that their relative movements and phase relationships change during operation. As shown, material passes from a breaker 1 of any known type between the first two of a series of rotating spiked rollers 8 of a stripping device 2. Rollers 8 are arranged around the path of rotation of flexible blades fixed to freely pivoted arms 7 rotating about shaft 4 and enclosed in casing 15, 16. Fibres are stripped by the rotating blades co-operating with rollers 8, and are projected obliquely onto a moving inclined openwork support 17, the straw or waste matter falling substantially vertically. Support 17 takes the form of a conveyer comprising angle bars 33 mounted transversely on endless chains 36, some angle bars being provided with upstanding pins 34. As fibres are carried upwards on conveyer 17, they are teased by comb teeth 22 which are caused to oscillate with shafts 21 by the engagement of cranked ends of the shafts 25 with slotted arms 23 also fixed to the shafts 21. Pulleys 27 fixed to shafts 25 are caused to rotate by a belt 28 passing alternately over and under these pulleys and driven from shaft 4 via pulley 32. Each comb 22 can yield to excessive resistance by the slipping of belt 28 on the corresponding pulley 27, so that although each comb moves intially in the opposite direction to the next the phases and directions of oscillation of the various combs become arbitrarily disposed. Combs 22 serve to open and regularize the fibres and disengage any residual straw, which then passes between bar 33 into pneumatic collectors 43. Any straw falling onto plate 41 arranged beneath conveyer 17 is carried into the collectors 43 by scrapers 45 mounted beneath the bars 33. Frame member 19 carrying shafts 21 is vertically adjustable relative to the main frame 18 so as to raise or lower combs 22 relative to support 17 and to vary the amplitude of oscillation thereof. The fibres are discharged and collected at the upper end of conveyers 17 or may be passed to a further teasing device with or without the interposition of a further stripping device.

Abstract: 1350655 Cathode-ray tube displays SIEMENS AG 19 April 1971 [9 April 1970] 26998/71 Heading H4T [Also in Divisions G4 and B6]  In apparatus for reproducing alphanumeric characters utilizing non-intermittent writing apparatus such as an ink jet printer or a constant intensity beam cathode-ray tube, the writing jet or beam is deflected by pulses of varying amplitude derived from digital signals from an information source gating steps of a jet-deflection staircase waveform. Each character is formed on a matrix basis, e.g. 7 x 5 and character signals held in a read only store are serialized into five successive groups of seven serial bits. A base frequency and sub-frequencies thereof are summed by binary weighted resistors to produce a staircase waveform extending over seven bit periods and is then gated by the character signals to produce jet-deflection pulses, the amplitude of which rises over a group of seven pulses but remains constant during each individual pulse. A capacitor may store the jetdeflection pulses between one pulse and the next to maintain the deflection of the jet.

Title: Process for the production of alkali sulphates and sulphur
IPC: C01D5/04
Filed: 1931-09-28
Abstract: Sulphur and alkali or ammonium sulphates are obtained from alkali or ammonium bisulphites, from mixtures containing these, or from sulphur dioxide with the intermediate formation of such bisulphites, by reacting them with calcium or other alkaline-earth metal sulphide in aqueous solution, separating the deposited alkaline-earth metal sulphite precipitated, and heating the remaining solution containing neutral alkali sulphite, alkali thiosulphate and alkali-trithionate at temperatures of about 80-180 DEG  C. under the pressure spontaneously produced in the reaction vessel or under higher pressure.  The CaSO3,2H2O precipitated in the reaction may be reconverted into calcium sulphide for further use by heating with solid, liquid or gaseous carbonaceous reducing agents.  Sulphur dioxide may be reacted with gaseous ammonia in the presence of sufficient water vapour or finely divided water to form ammonium bisulphite which is separated in the solid form by an electrostatic field or in a bag filter and is then employed in the above process.

Abstract: <PICT:1111268/C1/1> Tiles are glazed or enamelled in a furnace comprising a stationary hearth having bars 15 and fired by upwardly and downwardly movable upper and lower burner manifolds 5, 5 carrying cross-tubes 24, 24 having attached thereto burners 25, 25 supplying a uniform flameless heat to the tiles 26.  The manifolds are secured to guide bars 6 moved by a pulley and counterbalance system 8, 9, (10) to a firing position close above the tiles.  After firing, the manifolds are retracted quickly while the burners continue unabated, the tiles are removed therefrom and fresh unfired tiles are placed therebetween.  In a modification, Fig. 4 (not shown), a heat-reflecting shield (30-33) surrounds the hearth and is attached to the manifolds to move therewith without restricting movement thereof.  In a further embodiment, one manifold may be fixed while the other and the hearth have a co-ordinated differential rate movement therefrom.  In another embodiment (Fig. 5, not shown) receiving tables (50), (51) disposed laterally of the hearth receive unfired and fired ware respectively, a ram (53) being used in conjunction with the table (50).  Figs. 6-8 (not shown) illustrate a hearth which shuttles between manifolds (60), (61), while Figs. 9, 10 (not shown) show a rotary or oscillating circular hearth split four parts mutually offset by 90 degrees and utilizing four diametrically opposed pairs of manifolds.

Abstract: 1467164 Making dynamo-electric machines SIEMENS AG 19 June 1974 [29 June 1973] 27290/74 Heading B3A A method of making a dynamo-electric machine comprises assembling a rotor 3, a wound stator core 1, and a housing together with a sealing sleeve 8 so as to define a casting mould, introducing a settable sealing composition, e.g. a casting resin 2, into the mould to seal the winding in position and removing the sleeve 8 through at least one opening 51 provided in the housing after the composition has set thereby defining a predetermined air gap between the stator core 1 and rotor 3. The sleeve 8 is inserted into the wound stator core 1 and end shields 5, 6 are secured to the core by rivets 20. The sleeve also serves to centre the rotor in the stator. A sieve-like foil 7 is placed in the shields 5, 6, prior to assembly on the stator core, the foil serving to shape the winding end turns and keep them a minimum distance away from the shields, which are conductive, for insulating purposes and to provide the heat dissipation required. Instead of foil, a fleece-like insert or plastics clips may be used or alternatively an insulating layer may be sintered on to the inner surface of the end shields. The sleeve may be helically wound and be removed by being pulled through an aperture in an end shield. The sleeve 8 may be formed of trapezoidal segments 81-88 which are disposed to provide lug-like projections 811-871. The projections are aligned with slots in the end shields 5, 6 and projects through them to allow for removal when the casting resin 2 has set. The sleeve may be removed by melting out. The end shields may have provision for accommodating radially disposed cooling tubes (13), Fig. 3 (not shown), or electric components (14), Fig. 4 (not shown). The end shields 5, 6 may also be provided with apertures (16), (17), Fig. 5 (not shown), into which the casting flows and on curing anchors the end shields against axial and rotary movement.

Oct. 4, 1933, No. 27300. Convention date, Nov. 4, 1932. [Class 40 (v).] A diode rectifier is prevented from rectifying impressed radio frequency voltages until the peak rises to a valve substantially greater than the D.C. potential between its electrodes. The diode is shown applied to a receiver for producing delayed automatic volume control. The valve 9 comprises a filament F, two grids G1, G2, and a plate P. Signals from the tuned input coil are applied through condensers 6, 7, 8 to the grids and the plate. The electrodes G1, F act as a diode signal rectifier, low frequency currents being developed across a resistance 10 connected therebetween and led to a L.F. amplifier over the lead 11. The plate P is biassed negatively from a tapping 13 on a source 14 through a resistance 12 and, with the filament, acts as a delayed gain control diode rectifier, the gain control potentials being taken from the plate P through a filter 15, 16 and feed resistances 20 to the grids G of high frequency amplifying valves 3 which thus normally receive the same bias as the plate P. The diode P F is prevented from rectifying the H.F. input until the bias on the grid G2 is overcome. This grid is biassed more negatively than the plate P through a resistance 23 from the source 14.
