Title: Improved wall paper and method and apparatus for producing same
IPC: D21H19/06
Filed: 1953-03-12
Abstract: 745,541. Coating fabrics successively with adhesive and pulverulent material. SOC. FRANCAISE DES PAPIERS PEINTS. March 12, 1953 [Sept. 26, 1952; Feb. 13, 1953], No. 6865/53. Class 140. [Also in Groups XV and XVI] Relief wall-papers are produced by first printing a relief ink-impression and then distributing pulverulent material uniformly on to the printed surface while the ink is still moist, the distribution being effected by blowing a stream of air conveying the material above the moving paper; the excess material is subsequently removed. The pulverulent material may be bronze or other metallic powder, mother-of-pearl, cotton, or wood, and may be in the form of powder, flakes or small rods. The design is produced with an adhesive substance in relief and of varying depth in a printing- machine, and the pulverulent material adheres to it in greatest concentration at the deepest parts and not at all in the non-design areas. The paper is passed from a printing-machine through a distributing box 2, Fig. 1, having an input compartment 5 and a distribution compartment 6, and through a drying apparatus 34 to a windup means. Bronze powder is contained in a hopper 10 having a needle valve 11 raised by an electromagnet 12 by an amount adjustable by a screw-operated means 13. The powder, including any that has leaked into compartment 5, is sucked into a blowing-machine 8, and blown out through an elongated nozzle 18 having an output-controlling adjustable flap 19. on to the whole width of the paper as it passes through the compartment 6. A helical powder-dispersing deflector 17, and a vibrator 15a to prevent powder depositing on the walls of the nozzle are provided-also a powder-diluting auxiliary air intake 20. Surplus powder is sucked away through a hood 21 by a suction fan 23 and collected in a bag 24.

Title: Improvements in or relating to firing mechanism for automatic guns
IPC: F41A19/31
Filed: 1943-05-01
Abstract: 574,553. Automatic guns. DUNLOP RUBBER CO., Ltd., TREVASKIS, H. W., and HERCKLEBOUT, L. May 1, 1943, No. 6915. [Class 92 (ii)] The firing mechanism of an automatic gun comprises a sear 14, Fig. 5, which is pivotally connected at 15 to a sear beam 16 pivoted at 32 to the sear slide 18, the arrangement being such that the sear is moved angularly by the breech block 19 out of the path of the breech block when the trigger is pulled. The sear is normally held in its operative position in alignment with the sear beam by a pivoted member 12 which engages beneath its toe 14b, and is urged upwardly by a spring 25, a further spring, not shown, also being provided to urge the sear beam upwardly about its pivot 32. A second pivoted member 13 is fitted with a spring- controlled detent 13b adapted to engage with the toe of sear beam 16. As shown diagrammatically in Fig. 3, the firing mechanism includes a solenoid 1 having two cores 2, 3, which are connected by links 4, 9 to the opposite arms of a lever pivoted at 7. The link 9 is acted upon by a spring 10 and has recesses 9a, 9b which coact respectively with the two members 12, 13. When a firing button is pressed, the link 9 is moved by the cores to the left and carries with it the members 12, 13 to the position shown in Fig. 5. The sear 14 now being unsupported by members 12 is tilted by the breech block under the action of the main spring 20, and its toe 14c engages with a fixed plate 28. Thus, the sear beam is also rotated about its pivot and is eventually held in its depressed position by the detent 13b on member 13. The sear now being clear of the breech block, automatic firing takes place, the sear in the meantime being returned by spring 25 into substantial alignment with the depressed sear beam. When the firing button is released the link 9 is moved by spring 10 to the right, carrying members 12, 13 with it. Detent 13b thus moves clear of the sear beam and the latter with the sear are carried upwardly by their springs to the initial position. When re-engagement of the sear with the breech block occurs, the energy is partly absorbed by a spring 21, carried by the sear beam and bearing against pivot 15, and partly by a fibre block 31 at the forward end of the sear slide.

Title: Improvements in or relating to dyestuffs and dyestuff intermediates
IPC: C09B23/04
Filed: 1940-04-19
Abstract: 540,577. Photographic sensitizing dyes; dyeing cellulose esters. KENDALL, J. D., and FRY, D. J. April 19, 1940, No. 7077. [Classes 2 (iii) and 15 (ii)] [Also in Group XX] Dyestuffs which may be used for sensitizing photographic silver halide emulsions or for dyeing textiles, particularly cellulose acetate artificial silk, are made by condensing together two molecular equivalents of an N-hydrocarbonsubstituted rhodanic acid in the presence of an anhydride or ortho ester of a monocarboxylic acid and a strong base. As substituted rhodanic acids, N-alkyl, N-aryl and N-aralkyl derivatives may be used, including the N-methyl, ethyl and higher alkyl derivatives, N-phenyl and naphthyl derivatives, and N-benzyl and phenylethyl derivatives. As acid anhydrides, acetic, propionic, butyric, benzoic and phenylacetic anhydrides are specified, and the alkyl, aryl and aralkyl esters of the ortho forms of the same acids and of ortho-formic acid may be used. The base employed is preferably an organic base stronger than ammonia, particularly triethylamine, but inorganic bases such as potassium acetate may also be used. The products may be employed as intermediates for the production of other dyestuffs, as described in Specification 540,578. In examples, dye stuffs are made from N-methyl or N-ethylrhodanic acid and acetic anhydride or ethyl orthoformate, and from N-methylrhodanic acid and propionic anhydride, triethylamine being used as the base. In the use of the dyestuffs for dyeing cellulose acetate fabrics, the dyebaths may be simple aqueous solutions, where the dyestuffs are sufficiently soluble, or the dyestuffs may be dispersed with the acid of the usual dispersing agents, e.g. turkey red oil, sulphoricinoleic acid, naphthenic and sulphonated naphthenic acids, sulphonated naphthalene-formaldehyde condensation products and sulphonated long chain fatty alcohols. Examples of the dyeing process are given. The Provisional Specification describes also the use of unsubstituted rhodanic acid, and of 2-thio-4-keto-tetrahydro-oxazole and its N-alkyl, N-aryl, and N-aralkyl derivatives as parent materials.

Title: Side pincushion distortion correction circuitry
IPC: H04N3/16
Filed: 1973-02-13
Abstract: 1419304 Cathode-ray tube circuits TOKYO SHIBAURA ELECTRIC CO Ltd 13 Feb 1973 [15 Feb 1972] 7109/73 Heading H4T In a side (E-W) pincushion distortion correction circuit for a colour television receiver, the correction being effected by means of a saturable reactor having a working winding connected in series with the horizontal deflector coil(s) and the control winding supplied with a vertical frequency scan current waveform adverse effects resulting from inherent modulation of the amplitude and width of horizontal fly-back pulses (e.g. phase change of the horizontal deflection signal when an automatic frequency control circuit is employed and variation in fly-back derived operating potentials such as the EHT) are prevented from occurring by means of a second saturable reactor having its working winding effectively connected in parallel with the horizontal deflection coils and its control winding supplied with a vertical frequency scan current waveform of opposite phase to that supplied to the control winding of the first saturable reactor. With this arrangement the effective inductive loading of the horizontal deflection circuit remains substantially constant and the modulation of the fly-back pulses does not occur. Fig. 3A shows one embodiment in which the working winding of the first saturable reactor 15 is connected in series with the line deflection coil 14 and the working winding of the second saturable reactor 18 connected directly in parallel with the coil 14, the control winding of reactor 15 being connected at X to the vertical output circuit 16 (Fig. 3B) and the control winding of reactor 18 connected to point Y of this circuit. Due to the action of an integration circuit 17 the current Id1 flowing in the control winding of reactor 15 has a parabolic waveform (Fig. 6, not shown) and the current flowing in the control winding of reactor 18 has a sawtooth waveform (Fig. 8, not shown) and produces a variation in the inductance of its working winding which is of opposite phase to that produced in the inductance of the working winding of reactor 15 so that the overall inductive loading of the horizontal deflection circuit is substantially constant. Instead of connecting the working winding of the reactor 18 directly in parallel with the horizontal deflection coils it may be connected in parallel with the primary of the line fly-back transformer (Fig. 9, not shown); in parallel with a tapped portion of this primary (Fig. 10, not shown) or in parallel with an additional secondary winding on this transformer (Fig. 1, not shown).

Abstract: 373,681. Storing and delivering gun cartridges. BRUCE, R. A. and PETTERS, Ltd., Westland Aircraft Works, Yeovil, Somerset. March 7,1931, No. 7169. [Classes 9 (i) and 92 (ii).] Means for storing and delivering ammunition particularly on aircraft comprises a cage g which supports separate concentric rows of ammunition, as shown in Fig. 7, each cartridge being in an individual compartment. Further, the cage is rotated step by step between a fixed drum d and an external casing a through the medium of a hand-wheel s to enable cartridges to be inserted in the compartments through openings o, n and to permit of delivering the cartridges by way of stationary shoots r, q associated one with each row. In the device shown, there are twice as many cartridges in the outer row as in the inner row and the wheel s is chain-geared to the drum so that at each quarter-revolution of the wheel a cartridge is delivered from the shoot r and at each halfrevolution both shoots deliver a cartridge. The step-by-step rotation of the wheel s is controlled by a finger-operated catch t, Fig. 4, engaging notches at 90‹ apart in a disc u. To indicate the number of cartridges remaining in the device, a numeral disc v is rotated from the hand-wheel shaft m through gearing w, x. The disc can be rotated for resetting after pressing it laterally against a spring support 7 to disengage the gear.

Title: Improvements in or relating to control systems for engine-starting polyphase induction motors
Filed: 1947-03-14
Abstract: 623,787. Starting prime movers. SIMMS, T. E. March 14, 1947, No. 7188. [Class 38 (iv)] A gas turbine or other engine is started by a polyphase induction motor 6 supplied from an alternator 5 driven by an auxiliary engine 1 through an eddy current or like slip coupling 4a-4c, whereby the alternator is gradually accelerated from rest so that the motor receives an input of progressively increasing voltage and frequency, with consequent reduction of starting losses. The auxiliary engine, which may also be a gas turbine, may drive the coupling through a gear box 3, and also drives an exciter 2 for the alternator and coupling fields. The coupling may be of the double caged type which transmits a substantially constant torque. In the system shown, closure of a master switch 9 and a push-button 10 closes contactors 12, 13, thereby energizing the coupling over circuit 11 and completing a circuit 14 to the miscellaneous starting accessories of the turbine. Assuming engine 1 to be running, the turbine is consequently run up, and upon the line current to motor 6 falling to a value corresponding to the turbine becoming self-running a contactor 15 opens and de-energizes the coupling, thereby cutting the supply to the motor. Alternatively, the contactor 15 may be controlled by the voltage or frequency of the alternator. The set may be used for starting the propulsion motors of aircraft, the alternator normally supplying the electrical services of the craft. Alternatively, the elements 1-5 of the set may be mounted on a mobile ground starting-truck.
