Title: Wireless television method and arrangement
IPC: H04N7/06
Filed: 1935-02-09
Abstract: 451,670. Television. RADIOAKT.- GES. D. S. LOEWE, 10, Wiesenweg, Steglitz, Berlin. Feb. 9, 1935, Nos. 4204 and 4205. Convention dates, Feb. 9, 1934 and April 28, 1934. [Class 40 (v)] Relates to a system as disclosed in Specification 392,456, in which sound and vision signals are transmitted on adjacent carrier waves which at the receiver are heterodyned by a single local oscillation producing two intermediate frequencies. According to the invention, the sound intermediate frequency is lower than the vision intermediate frequency preferably by one order of magnitude, the local frequency preferably lying between the sound and vision carriers. The two transmitted carriers differ in their wavelengths by approximately 2 per cent so that both can be received on a tuned aerial 1, Fig. 2, coupled over a line 2, transformer 3 and a differential condenser 5 to the tuned circuit 6, 7 of an oscillator 4 which acts as an anode bend detector by virtue of the bias set up across the resistance 8 by grid current. The two intermediate frequencies so produced are fed over a coupling 9, 10 to an amplifier 11. The coupling 9, 10 may be such as to give equal or greater coupling for the sound intermediate frequency as compared with the vision intermediate frequency. The resistance 9 may be replaced by a tuned circuit 12, 13 damped by a resistance 14 to the required band-pass. The two intermediate frequencies are separated in the anode circuit of the valve 11 by a band-pass filter 16, 17, 18, 19 for the sound intermediate frequency and an inductance 21 for the vision intermediate frequency. The filter 16, 17, 18, 19 has a band-pass wide enough to allow for variations in the intermediate frequency due to variations in the local oscillator. Alternatively the two intermediate frequencies may be separated by inductively coupled band-pass filters, in which the ratio C/L is small for the image intermediate frequency and large for the vision intermediate frequency. The two intermediate frequencies are then separately amplified to the desired degree, Fig. 3, (not shown). The two intermediate frequency amplifiers may have their gain control adjusted independently or in unison. The two carriers should be spaced by a frequency range at least three times greater than the maximum image frequency to be transmitted. The spacing of two transmitters, should be smaller than the spacing of the transmitted sound and vision carriers of one of them.

Title: Improvements in or relating to tire building drums
IPC: B29D30/24
Filed: 1954-02-15
Abstract: 752,808. Tyre - building machines. NATIONAL-STANDARD CO. Feb. 15, 1954 [March 4, 1953], No. 4350/54. Class 144 (1). The building surface of tyrebuilding drum is formed of a plurality of longitudinal staves each made of telescopically arranged sections with inwardly directed radial posts in the end sections resting on expanders movable along the axis of the drum to expand the drum circumferentially and means connected to said end sections vary the length of the staves simultaneously to vary the width of the drum. As shown, the drum surface comprises staves 30 arranged circumferentially to constitute the drum proper, each stave being composed of a short central section 31 secured to bars 32 extending on each side and having a close sliding fit in grooves in end sections 34, 35. Attached to the central section and overlapping the end sections are metal cover-plates 38 arcuate in cross-section. The sections 34, 35 are supported by posts 40, 46 resting upon expander cones 12, 14, each post having an inclined surface 43 slidable over the conical surface of cone 12 or 14 and with a flat surface 44 which rests on the surface 20 or 20a of the cone. Endless springs 55 seated in grooves 54 near the outer edges of sections 34, 35 hold the staves in circular form. Cone 12 is fixed within a cylinder 18 by screwing on to a sleeve 3 secured to the drum supporting shaft 6 and cone 14 secured on shaft 1 as by split-rings 15, Fig. 1A, is movable within the cylinder, its posts 46 passing through slots 50 in the cylinder and through holes 47 in the auxiliary drum 25 supporting the outboard folding tube 26 inflatable as indicated at 22 for the inboard folding tube 23, Fig. 1A. Cone 14 is moved to the left by rotation of the shaft 1 screw-threaded into the sleeve 3. Rotation of a shaft 62 rotatably secured in auxiliary drum 25 and screw-threaded as at 65 into an inboard auxiliary drum 22 moves drum 25 away from the drum 22 to allow increase of the building drum width and the sections 31 are shifted by hand to maintain them centrally between the drums 22 and 25. A consequential adjustment of cone 14 is obtained by rotation of shaft 1 to bring the cone into the same relationship with the posts 46 as shown in Fig. 1A. The shaft 1 is then moved manually or by mechanical or pneumatic means, to the left relative to the drum 18 to move the cones 12, 14 together relative to the posts 40, 46 to adjust the diameter of the drum. Hollow shafts 6 and 1 conduct fluid under pressure to the folding tube 26, the folding tube 23 receiving fluid under pressure through a tube 95 from a central chamber at the inboard end into which the shaft 6 passes. Specifications 637,621 and 683,785 are referred to.

Title: Improvements in or relating to the production of iodo-substituted salicylic acids
IPC: C07C51/363
Filed: 1936-02-17
Abstract: Mono- and di-iodo-salicylic acids are made by the reaction of iodine with salicylic acid in aqueous-alcoholic solution and in the presence of iodic acid.  The iodo-acids are precipitated with water and may be separated by dissolving in an alkaline solution of an alkali or alkaline earth metal salt, preferably a carbonate, and cooling the saturated solution whereby the salt of the di-iodo-acid crystallizes first.  The acids may be converted into their acetyl derivatives from which salts are obtained by reaction with compounds of alkalis, alkaline earths, Bi, Hg, Ag, Pb, U, As or Sb.  Quinine, caffeine, theobromine, or piperazine iodoacetyl-salicylates may also be prepared.  In an example, salicylic acid in 33 per cent alcohol is treated with the equivalent amount of iodine at about 100 DEG  C. until solution occurs.  10 per cent iodic acid is then added. Specification 5490/96, [Class 2], is referred to.  The Specification as open to inspection under Sect. 91 comprises also the reaction of iodine with salicylic acid in alkaline solution and in the presence of sulphuric ether.  The iodoacids are acetylated with acetic anhydride, if desired with the addition of an alkaline acetate, or with acetyl chloride in pyridine.  This subject-matter does not appear in the Specification as accepted.ALSO:Salts of iodo-acetyl-salicylic acids are prepared by reaction of the acids with compounds of Bi, Hg, Ag, Pb, U, As or Sb.

Abstract: Cyclised rubbers having the same C : H ratio as rubber but less chemical unsaturation than rubber, are prepared by heating a mixture of 100 parts of rubber, 15 to 30 parts of an alkali metal alum, 2 to 8 parts of phosphorus pentoxide, and 0.2 to 5.0 parts of sulphuric acid.  From 1 to 3 parts of sulphur, selenium or tellurium may also be added and the mixture heated in sections 1/8 inch to 1/4 inch in thickness at 278-325 DEG F. at low oxygen concentration.  The product may be used as a rubber to metal adhesive by dissolving it in gasoline containing 3 to 5 per cent. of butyl alcohol or in an aromatic solvent such as benzene. To the solid product may be added 5 to 50 per cent. of sulphur, selenium or tellurium together with accelerators such as 2, 4, diaminodiphenylamine, antioxidants such as acetone-aniline condensation products and the substance known under the Registered Trade Mark "Neozone," also magnesium oxide, zinc oxide, carbon black and red iron oxide.  The sulphur, selenium or tellurium may be replaced wholly or in part by tetramethyl thiuram disulphide. A stronger bond may be obtained by incorporating some of the unvulcanised rubber to be bonded, in the adhesive before use.
