Patent GB-204117-A (GB)
Title: Improvements in film printing apparatus
IPC: G03B27/08
Filed: 1922-06-20
Abstract: 204,117. Wade, H., (PathÚ Exchange, Inc.). June 20, 1922. Printing-apparatus.-In film printing machines means are provided to cut the positive film at any desired moment or when the negative film has been printed, the cutting mechanism being controlled by hand or by the negative film. The positive film B, Fig. 1, passes round feed-rollers B<2>, B<4> the negative film C passes through a frame R, and both films pass through the printing aperture A‹. A pair of shears P, N, arranged adjacent to the film B comprises a fixed blade P, Fig. 3, and a swinging blade N, pivoted at n', and having an arm n to which is attached a tension spring 0 tending to move the blade N into the dotted position to cut the film B. The. blade N is held in the open position, Fig. 3, by a hook M<2>, on a lever M, pivoted at m<2>, and naving an adjustable weight M<1>. The blade N, in this position, holds an auxiliary electrical switch Q, Fig. 2, in the closed position. A rod' K', passing loosely through a block on the lever M, has an adjustable collar k<1>, and is pivoted to a lever K, Fig. 7, the end of which engages a cam G<1> on a disc G, which forms a part of a frictionclutch, and has an arcuate wedge-shaped cam @ on the face adjacent to a channel f‹ on a disc F<2> fixed to a shaft F' which is continuously driven while the machine is in operation. A hard metal ball g<1> is held, between the groove f‹ and the cam g, by a hook on the end of the arm H of a bell-crank lever, the other arm h<2> of which engages with the core of a solenoid I. On the frame R is a pivoted lever T, Fig. 8, having, on one end, a roller t engaging the edge of the film C, and, on the other end, a stop t<1> normally slightly separated from a< >stop t<3>. The rod T and the stop t<3> are electrically connected with the solenoid I. The edge of the film C has an indentation c located near the end of the film so that when the positive film is cut the ends of the two films will be practically coincident after the printing operation. When the roller t engages with the indentation c, contact is made between the stops t', t<3> and the core of the solenoid rises so that the arm H releases the ball g<1>. Duel to the rotation of the disc F<2> the ball g<1> wedges between the discs F<2>, G and' the cam G<1> is thus rotated. This motion lifts the rod K<1>, the collar k<1> of which actuates the lever M so that the hook M<2> releases the blade N of the shears which swings under the action of the spring 0 to cut the positive film B. At the same time the switch Q is opened so that the core of the solenoid I drops and allows the hook of the lever H to engage the ball g<1> after the cam G<1> has made one devolution only. The rod K<1> then falls, and the lever M is automatically restored to its initial position. The blade N is returned to the open position by hand after which another complete film may be printed. The positive film may be cut at any time by lifting the lever M.

Abstract: 660,799. Electric indicating systems. NATIONAAL LUCHTVAARLABORA TORIUM. June 25, 1948. [June 27, 1947] No. 17210/48. Class 40 (i). [Also in Groups XXXVI and XL (b)] In known apparatus for measuring the velocity of flow of a fluid, a helical rotor 3 is mounted in a casing through which the fluid passes so as to be rotated at a velocity proportional to the fluid flow velocity. This rotor carries a concentric disc 8 perforated with a number of evenly spaced holes so that the light passing from a source 6, through a condensing lens 7, and a recess in the casing in which the edge of the rotor moves, to a photo cell 9 is "chopped" the frequency of the output pulses of the photo-cell as measured by a.n electronic frequency meter being a measure of rotor speed. According to the invention, a temperature sensitive resistor 4 compensates the meter reading for a varying relation between rotor speed and fluid flow as the viscosity and specific gravity of the fluid varies with temperature. A number of such instruments may be successively switched to a single frequency measuring arrangement by a continuously driven switch which may be declutched at will. The photo-cell output pulses are amplified and fed to an electronic frequency meter (an embodiment of which appeared in the drawings as open to public inspection.

The polyurethane and tar-like materials are suitably used in a weight ratio of 7:3 to 3:7.  Suitable polyisocyanates are toluylene diisocyanates, diphenylmethane-4,41-diisocyanate and hexamethylene diisocyanate whilst the preferred polyhydroxyl compounds containing thioether groups are polyethers and polyacetals derived from thiodiglycol, 3,31-dihydroxydipropyl sulphide, 4,41-dihydroxydibutyl sulphide, g ,g 1-dihydroxydipropyl disulphide and b ,b 1-dihydroxydiethyltetra- (trior di-) sulphide suitably in combination with polyhydric alcohols such as ethylene glycol, 1,2-propane diol, 1,3-propane diol, 1,4-butane diol, 1,6-hexane diol, di- or tri-ethylene glycol, butane - bis - (b  - dihydroxyethylether), glycerol, trimethylol propane, pentaerythritol or mannitol.  Reaction products of alkylene oxides with sodium polysulphide and/or hydrogen sulphide and sulphur may also be used as the polyhydroxyl compound. The ratio of NCO to OH groups in the formation of the polyurethane is suitably between 1.4:1 and 2.5:1. Suitable bituminous materials are asphalts, bitumens, bitumens aromatized by a cracking process and coal tar. Storable compositions may be produced from anhydrous tars which do not contain reactive hydrogen atoms and for this purpose the tars may be pre-treated with mono- or poly-functional isocyanates. The tars may also be mixed with plasticizing polymers such as styrene polymers, cumaroneindene polymers, synthetic and natural rubber polymers and partially condensed phenol resins.  Solvents such as cyclohexanone, methyl cyclohexanone, aromatic hydrocarbons, ethylene glycol acetate and butyl acetate may be used in the formation of the composition. Pigments and fillers may be ground with the tar materials or with the polyurethane if anhydrous. Suitable fillers are carbon black, silica and asbestos fibres. Conventional polyurethane cross-linking agents may be added to optionally dissolved compositions, e.g. polyhydric alcohols and alkoxylation products thereof, diamines, ammonia, hydrazine, alkanolamines and mercaptoethanol.  Water absorbing agents such as zeolites, calcium oxide, magnesium hydride, orthoformic acid esters, trichloro-triethyl phosphite, phosphorus pentoxide, aluminium alkoxides and isocyanates may also be added to the tar before the latter is mixed with the polyurethane.
