Title: Improvements in and relating to the heat treatment of surface coatings on continuously moved strips
IPC: B05D3/04
Filed: 1952-06-13
Abstract: <PICT:0745516/III/1> A surface coating on a continuously, horizontally moving strip, e.g. lacquer on an alumimium or other metal strip, is polymerized by subjecting strip and coating to a continuously circulated heated gas which is repeatedly subdivided into partial currents which after one such subdivision act in pairs on the strip in opposite directions from the ends of the treatment zone.  An elongated casing encloses a heating chamber 1 and longitudinal passages 5 separated by a partition 4 from the chamber. and a fan 14 is connected at the suction side to the heating chamber 1 and at the pressure side to one end of each passage 5, the other ends opening into the heating chamber.  The strip 2 travels along the chamber 1.  Each passage 5 divides at the end into two parts leading to oblique inlets 11 one on each side of he chamber 1. Outlet slots 12 for the circulated gas are provided on both sides of the chamber. The gas is heated by an electric or other heater 16.  Volatile substances given off by the coating are withdrawn through a damper-controlled pipe 17.  A damper 7 controls the proportions of gas flowing through the two passages 5.  The bottom of the chamber is concave in cross-section, so that if the strip sags unduly only its edges will touch the walls.  A plurality of strips may run through the chamber side by side.

Title: Improvements in resin coated fibre base and process of making
IPC: D06M15/263
Filed: 1944-08-09
Abstract: A porous and flexible fibrous base is coated first with a vinyl resin obtained by the copolymerization of an alpha-beta unsaturated carboxylic acid and a vinyl halide with or without another vinyl compound and then with a second substantially insoluble vinyl resin containing vinyl chloride.  The first resin, which is intended to adhere closely to the base, may consist of vinyl chloride and vinyl acetate and one of the following acids or their anhydrides or acid salts and esters: maleic, fumaric, benzylmaleic, citraconic, itaconic, phenylmaleic, chlormaleic, crotonic, acrylic, methacrylic. This resin may be applied as a solution in acetone or methyl ethyl ketone to which toluene or naphtha may be added.  Alternatively, the resin may be softened by cyclohexanone or dimethyl sebacate and calendered on to the base.  The coating resin is applied by heat and pressure and may contain vinyl chloride and vinyl acetate as well as plasticisers, calendering lubricants, fillers, pigments and stabilizing agents from among the following: di-octyl phthalate, tricresyl phosphate, dibutyl phthalate butyl phthalyl butyl glycollate, acetyl tributyl citrate or other alkyl or aryl phosphates or phthalates, castor oil, stearic acid, lauric acid, cocoa butter, lead carbonate, calcium stearate, lead stearate, calcium carbonate, clay, aluminium hydrate, carbon black.  The coating composition may also contain as a fluxing agent, a lower molecular weight copolymer of vinyl chloride and a vinyl ester of a lower aliphatic acid.  The criterion of insolubility of the coating resin is defined in the Specification.  Whether or not any resin satisfies the criterion depends both on the average molecular weight and the proportion of vinyl chloride it contains.

Title: Aromatic, mild tobacco with reduced nicotine content and process for the production thereof
Inventor: THIENEMANN HEINZ
IPC: A24B15/24
Filed: 1954-05-24
Abstract: Nicotine extraction by water lyeing or the use of an organic solvent is effected with ammonia, ammonium bicarbonate or other alkaline substance present only in an amount exactly or approximately sufficient to liberate the quantity of nicotine originally combined with phosphoric acid, the actual amount used being preferably that necessary just to displace the combined nicotine if it all existed as the primary phosphate.  The alkaline substance may be added to the tobacco prior to and/or simultaneously with solvent extraction, prior to water lyeing, simultaneously with and/or after steam pretreatment of the tobacco, or may be added to the lyeing water.  Extraction using an organic solvent is described as being effected by the Soxhlet method and is preferably carried out whilst maintaining a water sump in the solvent vessel, and the alkaline substance may be added to a quantity of water sufficient to saturate the solvent. With water lyeing, which may be effected in two steps, a p  concentrate free from nicotine or of fixed nicotine content, and obtained from the extract yielded by the lyeing, is applied to the tobacco.  The concentrate may be obtained by boiling down at reduced pressure after nicotine liberation by an organic solvent, e.g. trichlorethylene, and may be acidified by citric or phosphoric acid, and contain a natural or synthetic aromatic substance or extract.  The de-nicotined tobacco may be roasted, or aromatized under vacuum with an alcoholic flavouring. Quantitative process examples are given.

Abstract: 757,145. Multiplex transmission. PHILIPS ELECTRICAL INDUSTRIES, Ltd. May 27, 1954 [May 30, 1953], No. 15734/54. Class 40 (4). In a voice-frequency telegraph signal system having a plurality of channels, the channels are divided into four groups and the group occupying the lowest band in the transmission medium has channel equipment producing signals, lying within the frequency bands of the middle two groups, which are transposed by group modulation with a frequency higher than the mid-band frequency to the lowermost position in the transmitted speech band. Group 3 of six channels occupying the band 420 c/s-1020 c/s in the transmission medium in the 24-channel system, Fig. 1, comprises an oscillator 11 keyed by a key 15 to produce an amplitude modulated or frequency shift signal in each channel. The oscillator frequencies for this group are in the band 1260 c/s-1860 c/s and the group is modulated by a 2280 c/s oscillation in a ring modulator 36 before being connected to the transmission line 23 via filter 38, amplifier 45 and hybrid transformer 46. Group 3 channel signals are selected by a filter 50 and after transposition to the 1260 c/s-1860 c/s band in a modulator 48 pass to channel equipments 7 for final demodulation. A 12-channel, frequency-diversity radio system in which a pair of V.F. channels spaced by 600 c/s is used for each telegraph signal and in which the lowermost group is transposed in the manner described above, is described with reference to Fig. 3 (not shown). A two-way telegraph system using 12 channels for each direction in which the six channels occupying the lowermost part of the spectrum in the transmission medium have channel equipment dealing with frequencies in the middle groups of the transmitted spectrum, is also described. In this system the 12-channel groups are separated by directional filters and omission of the two middle channels 1740 c/s and 1860 c/s to facilitate directional separation, is suggested. The application of the invention to a system having wayside stations is described with reference to Fig. 4 (not shown).
