Title: Improvements in and relating to self-filling fountain pens
IPC: B43K5/18
Filed: 1935-04-27
Abstract: 437,795. Fountain pens. DUNKERLEY, G., 1. Waldeck Grove, West Norwood, London. April 27, 1935, No. 12646. [Class 146 (iii)] In a fountain pen, an open tube D extends from the feed-bar A into the barrel C and opens to the atmosphere through a passage E in the feed-bar, one or more passages F in the feed-bar also connecting the barrel to the atmosphere so that when the nib-section B is inserted into a hollow stopper in an inkwell and inverted ink flows down the tube D into the barrel and air escapes through the passages F which, during writing, serve to feed ink to the nib. In order to facilitate the flow of ink into the reservoir, the end H of the tube D is cut obliquely, and no sharp bends are formed in the tube D and passage E. The tube D may be connected to the passage F and the passage E dispensed with. The passages E, F may diverge so as to be at diametrically opposite points at the lower end of the feed-bar.

Title: Improvements in and relating to art of coloring moving picture films
IPC: G03D15/00
Filed: 1920-05-07
Abstract: 166,397. Gillespie, E. S., and Mackey, G. G. May 7, 1920. Printing-surfaces; rotary machines; processes. -Films are coloured by means of rollers which are fitted with absorbent printing pads corresponding in area to the whole or a particular part of the picture to be coloured, the printing pads being mounted on parts of the roller separated by grooves which prevent running of the colours on the raised parts of the rollers with consequential blotching of the impressions produced. Means are described for preparing the printing pads for colouring moving or fixed objects. As shown in Figs. 8 and 11, the printing or colouring rollers 15 are formed of metal with raised parts 17 separated by grooves 16, and the dimensions of the rollers are standardized to correspond to standard picture films, so that films 20 to be coloured may be fed forwards by spurs 18 on the rollers and the printing pads on the parts 18 will register correctly with alternate pictures of a film, the remaining pictures being treated by a second roller as shown in Fig. 8, when all the pictures of a film are to be coloured, this arrangement being especially applicable for colouring the stationary parts of a film, e.g. a blue sky, or a green field. When it is desired to colour moving parts of a picture the printing pads 35, Fig. 2, are arranged helically around their cylinder and are separated by grooves which are preferably of the same size as one of the pictures of the film, but which may be thin grooves just wide enough to prevent blotching but permitting all the pictures of a film to be coloured by one roller. In this arrangement, the printing roller or the film is traversed longitudinally while printing occurs. The printing pads are obtained by cementing a base a of celluloid and a coating b of gelatine or the like absorbent material to each raised part 17 of the roller. The coating b is then printed on by a copy of the film which is treated as follows. The parts of the film corresponding to moving objects are cut out altogether, and then the film is treated with an ink which is absorbed only by the parts of the film not acted on by light. The coating b is thus printed, and the parts of the coating corresponding to this impression are cut away, so that when it is treated with an absorbent ink it will print a design corresponding to the exposed parts of the film, and the cut-away parts of the film, i.e. the parts corresponding to the moving objects.

Title: Improvements in sealing devices for bearings
IPC: F16C33/74
Filed: 1939-05-01
Abstract: 537,606. Stuffing,-boxes. AKTIEBOLAGET BOLINDER-MUNKTELL. May 1, 1939, No. 13014. Convention date, April 22. [A Specification was laid open to inspection under Sect. 91 of the Acts, Oct. 31, 1939.] [Class 122 (v)] A sealing device for bearings such as crankshaft bearirigs comprises a ring 40 of elastic non-metallic substance clamped radially between a bearing member 13, e.g. a bearing race journalled on a crankpin 11, and a rigid ring 44 sliding on the other surface, e.g. the surface 30 of the crankweb, the clamping being effected by circumferentially adjacent segments 41. These segments are pressed towards the surface 30 by an elastic ring 46 surrounding them, and their connection with the bearing member 13 and ring 44 may be effected by forming grooves in these members into which the rubber &c. of the ring 40 is pressed.

Title: Improvements in fuel supply systems for internal combustion engines
IPC: F02D9/00
Filed: 1940-08-15
Abstract: 543,260. Reciprocating pumps for liquids. BENDIX AVIATION CORPORATION. Aug. 15, 1940, No. 13047. Convention date, Aug. 18, 1939. [Class 102 (i)] [Also in Group XXVII] In order to separate vapour from the liquid fuel supply to a carburetter, the fuel is passed through a chamber 68, Fig. 2 having inlet at 66 above, and outlet at 84 below a fine mesh screen 128, which prevents the passage of vapour bubbles with the liquid, the vapour collecting at the top of the chamber until the surface of the liquid is lowered sufficiently, to depress a float 146 and open an escape valve 152, the vapour escaping by a pipe 74. The liquid fuel is forced through the outlet 84 by a pump 130 fitted with a by-pass valve 142 closed by a tension spring 144. When the fuel temperature and pressure are such as to promote the formation of vapour a further pump, arranged between the inlet 66 and the fuel tank, is brought into action by a capsule influenced by these characteristics and closing the switch of an electric motor driving the pump ; or an engine driven or hydraulic pump may be used. Again, the capsule may be under the influence of atmospheric pressure or be replaced by hand operation. The effect of this additional pump will be to agitate the fuel supplied to the chamber 68 and assist the release of vapour. A hand operated priming-pump may also be included between the fuel tank and the chamber 68. The pipe 84 leads the fuel past a valve 86, Fig. 3, controlled by diaphragms 168, 170, 172, 174, into a chamber 166, and then through a metering jet 188 to chamber 165 and pipe 192 leading to a valve 194, which is opened by the fuel pressure acting on a diaphragm 195, to inject fuel beyond the throttle 92 in the air intake 90. The diaphragm 168 is acted on at one side by the pressure at the air intake as communicated by tubes 206, chamber 202, and pipe 200, and at the opposite side by the pressure in a small Venturi 212 transmitted through a pipe 208. Vapour in the chamber 166 collects at the top and escapes past a float actuated valve 160.
Patent GB-1004114-A (GB)
Title: Improvements in or relating to a method of and a machine for writing
IPC: B41J2/105
Filed: 1962-04-04
Abstract: 1,004,114. Typewriters. PAILLARD S.A. April 4, 1962 [April 14, 1961], No. 13051/62. Heading B6F. A writing machine comprising a platen 11 and a writing head 6 adapted to emit a jet of ink toward the platen, wherein a potential difference is established between the head and platen to charge the jet of ink and first electric signals applied to electrodes 3 to deflect the jet of ink and hence trace out signs or characters, is characterized in that during writing, the writing head moves continuously relative to the paper supported by platen and second electric signals applied to said electrodes to correct for the continuous relative movement, so that the signs are traced without deformation. Writing heads E1 . . . E30 are mounted on a carrier 1 supported by leaf springs 9 and given a simple harmonic motion by a rotating cam 16. Each head traces four signs. A third electric signal of rectangular form is applied to the electrodes to cause a jump in potential between signs and hence space the signs apart. Means are provided for memorizing a complete line of signs and the 1st, 5th, 9th . . . &c. signs traced out by the heads E1 E2, E3 . . . &c. simultaneously. Additionally, the paper is moved at a constant speed perpendicularly to the lines of writing. Movement of the paper is corrected for by applying an electric signal of sawtooth form to the electrodes. Alternatively, the writing heads remain stationary, the paper alone moving as described above. The writing heads are supplied with ink from a reservoir 8. The height of the ink above the heads is maintained at a constant value, so that the hydrostatic pressure just balances the surface tension of the ink at the mouth of the writing head. Thus the ink is prevented from flowing out of the writing head in the absense of an electrostatic field. The tracing of a sign cannot be started immediately after a prolonged stoppage, due to contamination and evaporation of the ink at the mouth. Thus, at the instant of starting, the jet of ink is directed automatically on to a separate target for a period of 1 or 2 ms.

Title: Gas turbine engine fuel system
Inventor: JUBB ALBERT
IPC: F02C9/16
Filed: 1967-03-20
Abstract: 1,119,316. Gas turbine engine fuel systems. ROLLS-ROYCE Ltd. March 20, 1967, No. 13052/67. Heading F1G. A gas turbine engine fuel system comprises a conduit 1 for supplying fuel to engine burners 2 under the control of a control unit 5 in accordance with at least one engine variable (such as ambient and compressor pressures or pressure ratios, ambient and jet pipe temperatures, and the rotational speed of a main shaft or shafts of the engine), a by-pass passage 10 by-passing the control unit, a valve 14 controlling the flow downstream of the by-pass passage, a speed governor 15 controlling the valve 14 in accordance with the speed of a main shaft of the engine (e.g. the L. P. shaft), a valve 11 operable by a control device 12 for diverting the flow from the control unit 5 to the by-pass passage 10, and means 22 operable when the flow is diverted for at least initially reducing fuel flow to the engine to prevent surging of the latter. Preferably, the means 22 comprises a movable abutment for the governor spring 21 carried by a lever 23 under the control of a pilot's emergency control lever 24. If the control unit 5 fails, the pilot operates control device 12 to by-pass the control unit and move the abutment 22 to a minimum flow position in which the valve 14 reduces fuel flow to prevent engine surging which could be caused by a large change of flow. Thereafter, the pilot can control the fuel flow by varying the setting of the governor 15 by means of the lever 24. The lever 24 may be omitted, the lever 23 then being linked to the pilot's throttle control 6. In this case, if the control unit 5 fails, the pilot must move the control 6 to the idling position to avoid surging, before operating the control device 12. A further by-pass passage 27, under the control of a valve 30 operated in unison with valve 11 by the control device 12, is provided to divert the pilot fuel flow for pilot burners 26 from the control unit 5 if the latter fails. The fuel pump 3 is controlled by the fuel pressure in a line 33 which operates a servo device 4 which may comprise a piston for adjusting the inclination of a swash-plate.

Title: Process for the manufacture of aluminium oxide
IPC: C01F7/08
Filed: 1926-05-21
Abstract: 252,399. Aktieselskapet Norsk Aluminium Co. May 23, 1925, [Convention date]. Alumina; alkali aluminates.-Calcium aluminate slags are leached with a solution of alkali carbonate containing some caustic alkali (not over 10 grams per litre), the total' alkali present being in small excess over the alumina dissolved. The aluminate solution is then treated by the Bayer process to precipitate alumina, and the motherliquor is treated .with carbon dioxide so as to partially carbonate it, leaving about 10 per cent of the alkali in the caustic state, the remaining alumina, and any dissolved silica, remaining in solution. This solution, which may contain 8-9 per cent of total alkali, is ready for use again. Alternatively, a solution containing 3-4 per cent of total alkali (containing some caustic alkali) may be used for the leaching, the alumina being precipitated by a modified Bayer process wherein alumina is added and carbon dioxide is introduced gradually during agitation, but so as to leave some free caustic alkali in the motherliquor, which is then used again.

Filed: 1939-05-02
Abstract: 528,751. Hair combs. HOGG, F. D. May 2, 1939, No. 13117. [Class 131] Combs are cleaned by pressing them into a strip 11 of fabric, preferably skrim or gauze, stretched taut on a slotted frame 1 of curved form and having a straight slotted pivoted cover member 6 adapted to be bent down on to the lower part and to be secured by a sliding bail clip 9. The faces of the frame members may be serrated to grip the material between them. Preferably the material is doubled so that when released from the frame it may be pulled off the back of the comb, and the transverse threads of the material dragged through the teeth. The material may be wound off a spool carried by a bracket at the pivoted end of the frame and be cut by a knife supported on the frame. The material may be treated with a liquid or other cleaning preparation. If desired the strip may be left on the comb as shown in Fig. 9 for use in dressing the hair so that it acts in the manner of a brush. The supports 2 of the frame may have clips 2a to receive combs awaiting the cleaning operation. The fabric may be of such a character that fewer transverse threads are present on one side to facilitate removal from the comb.
