Patent GB-613163-A (GB)
Title: Improvements in or relating to electric printing apparatus
IPC: B41M1/42
Filed: 1946-06-13
Abstract: 613,163. Printing-machines. GOSS PRINTING PRESS CO., Ltd. June 13, 1946, No. 17769. Convention date, July 12, 1945. [Class 100(ii)] In the electrical method of printing in which the ink passes from an inked design cylinder under the action of an applied electromotive force across a narrow gap between the inked cylinder and a coacting cylinder around which the web or sheet to be printed passes, the electrical circuit is arranged to develop a periodically varying electrical force differential. As shown in Fig. 1 the web 14 is passed around a cylinder 16 and is spaced by a few thousandths of an inch from the inked design cylinder 10 which is connected to earth. The cylinder 16 is connected to a source 18 of a high positive electrical potential by means of a circuit comprising a variable high resistance 19 and a shunt circuit including a condenser 20 and a high resistance 21. The alternate charging and discharging of the condenser 20 causes a periodically varying difference of potential across the gap between the cylinder 10 and the web 14, and is adapted to prevent damage to the paper by arcing. In Fig. 3 the current from a source of high positive potential 68 passes through a stepup transformer one winding 80a of which is connected to a cylinder 66 around which the web passes, and the other winding 80b is connected to the output of a square wave generator 81 operating at a relatively low frequency. In a further modification the circuit is somewhat similar to that shown in Fig. 1, but the condenser 20 is replaced by means for periodically applying an additional high voltage D.C. potential across the resistance 21. In this form the width of gap between the cylinders 10. 16 is limited by wedge-shaped glass members arranged with a small gap only between their apices, and the cylinder 16 may be replaced by a small stationary metal bar. U.S.A. Specifications 1,820,194 and 2,224,391 are referred to.
Patent GB-475372-A (GB)
Title: Improvements in or relating to direction indicating means for use on land, air or water craft
IPC: G05D1/08
Filed: 1936-06-26
Abstract: 475,372. Electrical signalling systems. ASKANIA - WERKE AKT. - GES. VORM. CENTRALWERKSTATT DESSAU UND C. BAMBERG-FRIEDENAU. June 26, 1936, No. 17858. Convention date, June 26, 1935. [Class 40 (i)] [Also in Groups XXIX and XX] A direction-indicating or automatic-steering apparatus for land, water, or air craft, comprises a compass-controlled force-controller 1, of the type shown in Fig. 2, which controls, through a relay 6, an azimuth gyroscope 9 to maintain it in a set position with respect to the direction of the field of force and to prevent " wander." The gyroscope 9 is associated with a second force-controller, as shown in Fig. 2, to provide an impulse in conduits 37 and 38 on any change in direction of the craft, which impulse acts, when a valve 33 is set for automatic steering, on a rudder relay 41 to apply a correction to the rudder setting. The secondary elements of the two force-controllers are connected together by shafts 12, 12<1> and differential gearing 13, 13<1>, 13<11>, and can be adjusted together to change the course of the craft by operation of a motor 21 under control of a push-button device 28. The differential gear 13, 131 and 1311 permits the phase relation of the secondary elements of the force-controllers to be varied to compensate for variations in magnetic declination. For the apparatus to function as a direction-indicating device only, a change-over of the valve 33, and a switch 23 in the circuit of the motor 21, is effected which cuts out the rudder relay 41 and directs the impulses from the gyroscopic controller 9 to a relay 26 which controls the motor 21 to provide a " follow-up " of the secondary elements of the force-controllers upon any change of course, which is indicated by compass cards 17 geared to the shafts 12 and 121. When the device acts thus as an indicator the independent adjustment of the secondary elements of the controllers must not be permitted and to this end the switch 23, operated with the changeover valve 33, cuts out the push-button device 28.

Abstract: 578,305. Boiler furnaces. HURLEY, T. F., PERCIVAL, G., FLAWS, L. J., and SHUTTLEWORTH, F. Dec. 16, 1942, No. 17915. [Class 51 (i)] The production of smoke from the fires of coal fired, natural draught, shell type boilers is reduced by providing throughout the firing cycle a supply of secondary air from the furnace front, the total area of the openings through which it is supplied being increased automatically after each opening of the fire door being subsequently reduced manually when the evolution of volatile matter has abated. The counter-weighted door 9, Fig. 2, is furnished with a baffle 14 spaced therefrom and, after the door has been opened, is retained in the position shown by a catch 18 whereby secondary air is supplied through an orifice 16; on lifting the catch the door closes. Secondary air is independently supplied through controllable openings 24 in the furnace front leading to top and side baffle castings 4, 5 from which it passes to the furnace through openings 22, 23, Fig. 4. The baffle 14 is provided with slits and the door with small perforations whereby some secondary air passes through the door when closed.

Title: Improvements in or relating to paper-folding machines
IPC: B65H45/22
Filed: 1936-06-27
Abstract: 477,410. Paper-folding machines. ISACHSEN, D. June 27, 1936, No. 17928. [Class 100 (i)] In a machine for making paper wrappers, towels, or the like, one or more paper webs are slit into narrower webs each of which passes through a longitudinal folding-device comprising flat parallel folding-plates, the folded webs being subsequently cut into the separate articles by a reciprocating knife. The web or webs 8, 81 pass between slitters 5 and then through sets of folding devices 22. From continuously-rotating feed-rolls 6 the folded webs pass over a guide roller 35 between a fixed bar 36 and a reciprocating bar 37 to fast-moving feed-rollers 7 and a reciprocating cutter 43. Prior to the operation of the cutter 43, the bars 36, 37 grip the webs so that a loop is formed between the bars and the rollers 6, this loop being taken up by the feed-rolls 7 when the webs are released. The cut pieces of folded paper fall on to a platform 46. Each folding-device comprises a plate 24 under which a web passes and is bent over its edges, and two plates 25 slightly spaced therefrom. The side portions of the web pass between the plates 25 and are bent outwardly over their inner edges, rollers 30 on levers 31 pressing down the folds so formed.

Patent GB-815891-A (GB)
Title: Process for the manufacture of titanium dioxide
Inventor: RICHMOND JAMES THOMSON
IPC: C01G23/07
Filed: 1954-06-18
Abstract: Titanium dioxide is produced by reacting a titanium tetrahalide other than fluoride with oxygen or a gas containing oxygen within a fluidized bed of solids at 750-1250 DEG  C., said titanium tetrahalide containing the vapour of titanium trichloride, aluminium chloride or silicon chloride, and the space velocity of the fluidizing gases being such that at least the greater part of the titanium dioxide formed is carried out of the bed.  The reaction may be initiated by external heating or by burning a combustible gas or liquid fuel such as carbon monoxide or gas oil in the bed or by separately introducing the tetrahalide and oxidizing gas preheated to a sufficient temperature.  Thereafter heat may be extracted or supplied as desired, e.g. by introducing carbon monoxide or liquid fuel with the oxidizing gas.  Water vapour may be introduced per se or as a substance yielding it at reaction temperature.  The fluidized particles may have a catalytic effect or may be inert and sizes of 0.001-0.1 inch are convenient.  Alumina or silica particles may be used but the use of titania for some or all of the particles is advantageous. According to the Provisional Specification, where titania particles are used, any particles formed by the reaction which remain in the bed may be allowed to remain thus or if practicable separated by sieving, whereas in the case of other materials, use is made in separating of such properties as particle size, density and solubility.  The tetrahalide used should for some purposes contain less than 0.1 per cent each of vanadium, iron and chromium (as V2O5, Fe2O3 and Cr2O3). An example is given in which a mixture of purified titanium tetrachloride vapour, aluminium chloride vapour, oxygen containing a small quantity of water and nitrogen are passed through a bed of titanium dioxide particles at 1080 DEG  C. and details are also given of a similar process using titanium trichloride in the place of aluminium chloride.  The Provisional Specification is not limited to the use of titanium trichloride, aluminium chloride or silicon chloride with the titanium tetrahalide or to fluidizing velocities such that the greater part of the oxide formed is carried out of the bed.

Title: Improvements in or relating to the manufacture of artificial textile fibres
IPC: D01D5/22
Filed: 1927-07-09
Abstract: 300,221. Sever, W., and Speakman, J. B. July 9, 1927. Apparatus for making filaments.- Artificial textile fibres having wave or curl similar to that of natural fibres such as wool or cotton are made by spinning a fluid medium of any suitable kind into a liquid or gaseous coagulating medium to which a swirling or eddying motion is imparted near the spinneret. The coagulating medium may be given any kind of motion which will result in the production of swirling or eddying currents near the spinneret. For example, motion may be imparted to the coagulating medium by means of a reciprocating plate surrounding or close to the spinneret, or the coagulating medium may be given a sufficiently high rate of flow, or two or more streams of coagulating medium may be caused to meet near the spinneret. Simple harmonic motion imparted to the coagulating medium in a direction at a right-angle to the flow of the spinning medium produces in the fibres such forms as those shown in Fig. 1, a - - c. A second superposed motion of the coagulating medium, or reciprocating motion other than simple harmonic motion, produces more complex forms such as are shown in Fig. 2, a, b. Reciprocating motion of the coagulating motion in the direction of flow produces forms such as are shown in Fig. 3, a, b, such forms being capable of felting. Interchanging types of motion may be applied so as to prevent the fibres from subsequently slipping wholly into phase with each other.
