Title: Improvements in or relating to photography
IPC: G03C7/25
Filed: 1926-02-08
Abstract: 263,331. Technicolor Motion Picture Corporation, and Weaver, E. A. Feb. 8, 1926. Drawings to Specification. Colour photography; toning.-The optical-density gradations in the high light portions of dyeabsorbent photographic images are made more gradual than those in the half-tone portions so that the detail of the scene may be accurately reproduced; the coloured images may be used for "black and white " or colour kinematograph projection, for printing by imbibition, &c., and may be in the form of reliefs. The images may be produced by exposing the film both to uniformly distributed light, and, by contact printing or otherwise, to image-forming light; the exposures may be successive or simultaneous. The films may be exposed to the uniformly distributed light during the course of manufacture, so that the subsequent user may expose in the usual way, but for a shorter time. The film may be rendered absorptive to light of a particular colour, and the uniformly distributed light may be of that colour. Dyes for the purpose are set out in the Specification, and, when the invention is employed in conjunction with the invention described in Specification 263,650, the dye may be suitable for the purposes of both inventions. The exposure to uniform light may be approximately the threshold exposure, and both exposures are made from the same side of the film, either from the emulsion side or from the celluloid side. Either or both of the component images of a multicolour positive may be exposed to uniformly distributed light, and the colour effect of the finished picture may be regulated by variation of such exposure. The images may also be produced by exposing so as to record the detail in the high lights, staining the images, and subsequently washing them to remove a greater proportion of dye from the intermediate portions of the image than from the thicker and thinner portions.

IPC: G01G23/22
Filed: 1927-02-08
Abstract: 265,634. Maatschappij tot Vervaardiging van Snijmachines Volgens van Berkel's Patent en van Andere Werktuigen, (Assignees of Kuyt, J.). Feb, 8, 1926, [Convention date]. Dials and scales; multiple-indication apparatus.-In a computing weighing scale of variable capacity for indicating the monetary or other value of goods being weighed, a tabular chart with a plurality of sets of computations is arranged behind an apertured or windowed front plate the chart and/or plate being relatively manually displaceable to bring the appropriate set of readings to the apertures. In the form shown a stationary plate 1, Figs. 1 and 4, with a weight scale 2 and arcuate rows of apertures 3 is arranged in front of a tabular chart 4 of monetary values. The chart 4 is carried bv four eccentrics 5 on spindles 6 journaled in the plate 1 and bearings 18. Each spindle carries a sprocket wheel 7 around which passes a chain 8 operated by a handle 9 to adjust the set of values according to the capacity, the values being arranged circularly about the apertures in the front plate as shown in Fig. 5. The chart is held in set position by pins 10 on the eccentrics engaging recesses 11 in the plate 1. To avoid obliteration of the values by the relative movement of the chart and plate the chart is arranged to be axially displaceable by providing collars 16 on the spindles 6 with which engage the forked ends 15<a> of a four armed frame 12, 12<a> secured to a manually operated slidable rod 14. In a modification the values may ba arranged around the periphery of bars rotatable in unison by the handle 9.

Title: Improvements in Means for Controlling the Speed and Power of Internal Combustion Engines.
Inventor: ILLINGWORTH ALFRED HOLDEN
IPC: F02B75/02
Filed: 1916-03-10
Abstract: 106,836. Illingworth, A. H. March 10, 1916. Regulating. - A twostroke-cycle engine is regulated by acting upon the fuel supply so that the piston receives an impulse every fourth stroke onlv, and then, if necessary, the impulses are made to cease. In multicylinder engines, in order that the torque may be uniform during regulating, the cylinders are acted upon in groups, certain groups being put out ot action in succession and the cylinders of the remaining groups made to receive impulses at regular intervals of time once every four strokes. The invention may be used in addition to the method of governing by varying the quality of the charge or its quantity. The invention is described in connexion with engines in which the fuel is admitted to the air-transfer pipe 4, Fig. 2, between the crank case and the cylinder, and with engines in which the fuel is injected into the cylinder by a pump, Fig. 3. In the form shown in Fig. 2, the fuel nozzle 6 is normallv always open and is supplied with fuel from a float chamber 23, the top of which is open through a passage 24 with the transfer passage 4. When the number of fuel injections is to be halved, the nozzle is closed by a valve 5 on alternate revolutions. As shown, this is effected by a half-speed cam 1 which acts upon the valve spindle through a tappet lever 2 and a distance-piece D interposed in its path by hand or by a governor acting through a link B. An extreme movement of the piece D causes it to engage a hook F which holds the valve closed. A hand-mechanism for locking the shaft A and piece D in any one of three positions is described. The lever 2 may engage the valve spindle directly and be controlled by an axially sliding cam with a circular part 12 for holding the valve closed, another circular part 13 for leaving it open, and the part 1 for intermittent opening and closing. The cam is double-ended when alternative fuels are used. The air passage 24 may be controlled instead of the fuel nozzle. Fig. 3 shows the mechanism 1, 2, F, D A just described, as applied to the tappet 36 for working the plunger of a fuel pump P. In this case, the governor 45 also serves to regulate the length of the stroke of the plunger by adjusting a strut 31 upon it along the length of a lever 38, which is oscillated by the tappet 36 and slide 37. In an alternative construction, the suction valve of the pump may be held open by the governor acting directly upon it or through the half-speed mechanism. The mechanism 1, 2, F, D, A may be locked out of action by the bolt C<1>; the lever 43 is then fixed. and the yoke 26 attached to the governor turns about its end and adjusts the strut 31 only.

Title: Improvements in air tight sealing of the base and bulb of radio tubes of small size and a radio tube produced by this process, particularly a radio tube with a guide cam
IPC: H01J5/24
Filed: 1953-02-09
Abstract: 737,013. Discharge apparatus. EGYESULT IZZOLAMPA ES VILLAMOSSAGI R. T. Feb. 9,19S3[Feb. 18, 1952], No. 3584/53. Class 39 (1). While fusing the flat baseplate of a discharge tube to the envelope, both parts are clamped and rotated together, and the envelope is pressed towards the base, until a predetermined displacement, say 0.5-1 mm., is obtained, after which the pressure ceases. In the arrangement shown, the envelope 13 is fixed in a holder 15 by a spring 16. An enclosing cage 14 allows the holder a small vertical displacement. Initially, the holder is in its higher position; as the bottom of the glass envelope melts, the holder and envelope drop under their own weight, until the lower position is reached. Alternatively, the predetermined displacement may be effected by an external arm bearing on the top of the envelope. The invention is applicable to small radio tubes having a laterally extending guide pin.

Abstract: 607,580. Manual exchange systems. TELEFONAKTIEBOLAGET L. M. ERICSSON. Feb. 8, 1946, No. 4061. Convention date, Feb. 12, 1945. [Class 40 (iv)] In a local battery system the metering magnet M1 is connected up by the call indicator K and part of the magnetic circuit of M1 has such retentivity that its armature will be held after the indicator is replaced until a demagnetizing current releases it. As shown, M1 closes a contact 11 which holds even when the insertion of reply plug SP by the operator moves spring 4 and short-circuits M2, thus breaking the circuit of M1 and M3, the latter being a relay that may operate a night bell. If the called party is free, a calling plug RP is inserted into the multiple jack J1 of the called line and the operator rings the wanted line by means of a key OW in the cord circuit SN or a key OT in the operator's set TU. In either case the sleeve c2.of plug SP is connected to positive battery and a current is sent through M1 in a reverse direction to the original, thus demagnetizing it and on its release this circuit is broken at contact 11. The counting apparatus of the meter operates only on the return of M1 and thus only records a call when the other party actually has been called.

Filed: 1922-02-13
Abstract: 177,150. Grimonprez, A., and Petit, H. March 18, 1921, [Convention date]. Folding paper. - A machine for cutting off lengths of cigarette paper from a pair of webs and delivering them folded one into the other, comprises duplicate sets of feed-rollers for the two webs, two pairs of cutting- blades and two reciprocating folding- blades coacting with two pairs of folding-rollers, by which the folded papers are forwarded to two pairs of toothed interfolding-wheels, the latter delivering the interfolded papers on to a platform carried by a pair of vertically arranged endless bands operated by ratchets so as to lower the platform intermittently. In the arrangement shown, the webs are drawn off the spools 5, 6 by feed-rollers 7, 8, and thence between other feedrollers 18, 19 to the cutters 20, 21. The lower rollers of these pairs of feed-rollers are continuously driven, the upper ones rotating frictionally. During the cutting operation, the webs are held stationary by vertical plungers 10 situated between the front and rear pairs of feed-rollers and depressed by springs 12, the lengths of web which are drawn in meanwhile by the feed-rollers 7, 8 being looped up by a looping bar 15 carried by pivoted spring- lifted arms. The rear feed-rollers 18, 19, which contact very lightly with the webs to permit the necessary slipping during the stationary period, rotate twice as fast as the front feed-rollers 7, 8 so as to draw out the loops in the webs when the plungers 10 are raised by means of arms 66, 67, Fig. 6, actuated by a cam 69 and lever 68. The several papers are tucked by reciprocating blades 23 between pairs of folding-rollers 28, 29, and forwarded on to pairs of toothed wheels or discs 32, 33 carried on hubs 34 fitted with gears 35 driven by a worm 58, by which wheels or discs the folded papers are interfolded one with another and conveyed down an open-fronted box 38 on to a receiving plate 81 supported on projections 48, 49 on the descending runs of endless bands 41, 42 actuated intermittently by ratchet devices 61, 62. The interfolding toothed wheels 32, 33 project through slots in the sides of the box 38. Fig. 6 shows also a device for use in starting the machine, comprising a lever 80 carrying arms 77, 78, by the depression of which the arm 68 is raised so as to lift the web-clamping plungers 10, the two looping-bars 15 being depressed by the arms 77, 78, whereby the webs may be readily threaded between the front and rear feed-rollers.
