Abstract: 373,275. Wrapping-machines ; coating webs. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.-(American Machine & Foundry Co. ; 511, 5th Avenue, New York, U.S.A.) Feb. 23, 1931, No. 5602. [Class 94 (i).] In wrapping and heat-sealing packages, the web of wrapping-material, which may be of transparent cellulosic material or other material not readily capable of being heatsealed, is coated on the edges with longitudinal stripes of sealing compound. The web C is mounted on a shaft 12 on a bracket 11 of the wrapping-machine, and passes round rolls 30, 31, 32 and over a plate 33 with the forward end hanging over a roller 34. Receptacles 18, containing sealing compound such as equal parts of paraffin and resin, are suspended on arms 15, counterweighted at 26 so that rollers 17 are resiliently urged against the edges of the web, arms 23 pivoted at 14, 21 maintaining parallelism. The receptacles and associated linkage are transversely adjustable on a shaft 13 so as to be applicable to varying widths of web. An article P to be wrapped up is brought into position in front of a plunger 37 which advances and transfers it to a table 36, then in the lower position shown in broken lines. The web being carried along by this action, a sufficient length is unwound from the reel for the next package. Plates 39, mounted on the table 36, form the first end folds, and, upon the table rising to the upper position, resiliently mounted stationary folders 40 turn down the top end folds. The wrapper is severed from the web at any convenient stage. The end of the package is now as shown in Fig. 3, the adhesive W being disposed along the outside edges of the folds. Plates 42, 43 complete the end folding, the latter being heated so as to seal the package.

Title: Apparatus for indicating the vibration of turboengine rotor blades
Inventor: ZABLOTSKY IGOR EVGENIEVICH
IPC: G01H1/00
Filed: 1968-02-05
Abstract: 1,143,339. Detecting vibration in turbines, electrically. TSENTRALNY ORDENA LENINA INSTITUT AVIATSIONNOGO MOTOROSTROENIA IM. P.I. BARANOVA. Feb.5, 1968, No.5638/68. Heading G1N. Apparatus for indicating the vibration of the outer ends of turbine rotor blades relative to the blade roots, comprises a pulse transmitter 1 Fig. 1 fixed to a stationary part opposite to marks 9 (e. g. pins or recesses) on a disc 10 on the rotor shaft producing pulses 20 Fig. 5 as the marks 9 pass it. The angular pitch of the marks corresponds to that of the blades. A transmitter 2 is fixed to a stationary part adjacent the radially outer ends of the blades, is angularly displaced from transmitter 1 by an angle # 1 , and produces pulses 21 as the blade ends pass it. The angle of displacement of the transmitters is representative of a predetermined vibration amplitude to be indicated. Pulses 20 are shaped in a unit 3 to produce pulses 22. Pulses 21 are shaped in a unit 5 stretched in a unit 6 to produce pulses 23. Both sets of pulses are fed to a gate 4. Due to the initial displacement angle between transmitters, in the absence of vibration the pulses 20, 21 do not coincide and there is no output from gate 4. When vibration occurs the pulses from transmitter 2 are phase modulated and if the vibration amplitude becomes equal to or exceeds a pre-set value for one blade the phase displaced pulses 24 from transmitter 2 will either coincide with or lead the pulses 25 from transmitter 1, and pulses 26 27, will sometimes coincide, so that gate 4 will open producing pulses 28. The output of the gate is fed to a neon warning lamp 7 and to a recorder 8. Alternatively the transmitters may be positioned to sense: - interacting blade vibrations as illustrated in Fig. 2 (not shown); torsional vibrations of blade Fig. 3 (not shown); a plurality of vibration amplitude levels Fig. 4 (not shown). The transmitters may be capacitive or inductive.

Title: Improvements in or relating to compositions of matter containing film-forming polymeric esters and ethers
IPC: C08K5/13
Filed: 1937-03-04
Abstract: A composition of matter contains a film-forming polymeric ester or ether, such as cellulose ester or ether, polyvinyl ester or ether or poly-acrylic acid esters, and a chlorine derivative, obtainable by chlorinating in the phenylol nuclei only, polynuclear phenols of the formula <FORM:0491792/IV/1> where R1, R2 are hydrogen atoms or unsubstituted univalent hydrocarbon residues or together form an unsubstituted bivalent hydrocarbon residue, chlorination being effected so as to introduce at least one chlorine atom into each of said nuclei. Suitable chlorine derivatives are di-(3-chlor, 4 hydroxylphenyl) dimethylmethane, di-(4-hydroxy-3-5-dichlorphenyl) dimethylmethane, di-(4-hydroxy-3-chlorphenyl)methylmethane, di-(4-hydroxy-3.5-dichlorphenyl) methylmethane, di-(4-hydroxy-3,5-dichlorphenyl)ethylmethane, di-(4-hydroxy-3,5-dichlorphenyl)methylethylmethane, and di-(4 - hydroxy - 3, 5 - dichlorphenyl)propylmethane.  They may be made by chlorination of the corresponding phenolic compound in a suitable solvent, e.g. a lower fatty acid or in suspension, e.g. in a liquid chlorinated hydrocarbon, at a temperature of 0-50 DEG  C.  The compositions may be used for plastics, for films, or for impregnating fabrics.  Thus a suitable aeroplane fabric dope contains cellulose acetate, di(4 - hydroxy - 3, 5 - dichlorphenyl)dimethylmethane and aluminium powder.  The compositions may contain other plasticizers, synthetic resins, pigments, or dyes.  Examples describe (1) chlorination of diphenylol propane; (2) manufacture of film or foils from solutions in acetone of cellulose acetate, or in a benzeneacetone p  mixture of the product known under the Registered Trade Mark "Plextol A" together with chlorinated diphenylolpropane; (3) an aeroplane dope containing cellulose acetate or nitrocellulose, chlorinated diphenylolpropane, triphenyl or tricresyl phosphate, dimethoxyethyl phthalate, powdered aluminium, and as solvent a mixture of acetone, methyl ethyl ketone, alcohol, benzene, diacetone alcohol and cyclohexanone; (4) a moulding powder consisting of cellulose acetate nitrocellulose and chlorinated diphenylolpropane; (5) a composition for coating electrical cables contains cellulose acetate.  "Glyacon" (Registered Trade Mark) chlorinated diphenylol propane, methyl ethyl ketone and acetone; (6) lacquer compositions containing chlorinated diphenylol propane cellulose acetate or nitrocellulose, and if desired a natural resin, in a solvent mixture. Bromine derivatives may be employed in place of the chlorine derivatives. Specifications 369,944, 369,945, and 372,327 are referred to. According to the Provisional Specification the halogen derivatives may contain halogen atoms in the side chains as well as in the phenylol nuclei.  The halogen derivatives, e.g. di(4-hydroxy-monochlorphenol)dimethylmethane may be reacted with formaldehyde to form synthetic resins which may be used in cellulose derivative compositions.
