Title: Improvements in and relating to the drawing of slivers
IPC: D01H13/04
Filed: 1952-06-06
Abstract: 745,132. Spinning yarns. DEUTSCHER SPINNEREIMASCHINEN-BAU INGOLSTADT NIEDERLASSUNG DER SCHUBERT & SALZER MASCHINENFABRIK AKT.-GES. June 6, 1952 [June 15, 1951; May 14, 1952], No. 14360/52. Class 120 (3). Sliver emerging from a drawing frame is made thinner and simultaneously condensed by means of a pair of rollers following the frame and preceded by a condenser, and false twist is imparted to the sliver by means of a revolving tube. In the operation of the apparatus shown in Fig. 1, fibrous material passes through pairs of rollers 1-I, 2-II, 3-III, 4-IV, of a drawing frame, thence through a trumpet condenser to rollers 5-V which may be provided with a condensing groove and ring engaging therein. The sliver 12 supplied from rollers 5-V is twisted by a revolving tube 6 and drafted between rollers 5-V and calender rollers 7 and 8 and guided without loss of twist to a channel 101 of a revolving plate 10 through which it passes to a can 11; the rollers 7, 8 may have condensing grooves and rings. In order to strengthen the sliver at the points of transition from left-hand twist to right-hand twist and vice versa, each pair of slivers a and b is guided to the can in the form of a twin sliver so that the transition points 13 are staggered as represented in Fig. 2. This staggered effect may be produced by winding one of the slivers around the roller 9, as shown in Fig. 3, or the roller 7, the circumference of the roller corresponding to one half of the distance between adjacent points 13 ; alternatively the drive of each of the revolving tubes is periodically interrupted and is so controlled that the drive of one tube lags that of the other by one half interval.

Abstract: N-substituted terephthalamic acid esters are prepared by forming a solution of a monoester of terephthalic acid or a salt of a monoester of terephthalic acid and a primary amine in a tertiary amine and adding a phosphorus halide to the said solution.  The solution is preferably prepared with the aid of a hydrocarbon solvent such as benzene or toluene.  The salts are formed by reacting the esters with a metal oxide or hydroxide. Specified primary amines are methyl-, ethyl-, butyl-, hexyl-, octyl-, decyl-, dodecyl-, tetradecyl-, hexadecyl-, octadecyl-, eicosyl- and docosyl-amines and aniline. Specified tertiary amines are trimethyl-, triethyl-, tripropyl-, tributyl- and tridecyl-amines, and dimethyl-, diethyl- and dipropyl-anilines. Specified phosphorus halides are phosphorus tri-chloride or bromide or fluoride, phosphorus penta-chloride or bromide and phosphorus oxychloride or oxybromide.  The salts and esters are of the formula: <FORM:0786295/IV (b)/1> wherein R is a straight- or branched-chain, or cyclic, saturated or unsaturated hydrocarbon radical having 1-22 carbon atoms, X is a metal or an aliphatic hydrocarbon radical having from 1-22 carbon atoms and y is the valency of X.  Specified values of R are methyl, ethyl, propyl, n- or tert.-butyl, pentyl, 2-methylbutyl, 2 : 3-dimethyl-butyl or hexyl, 2-ethylhexyl, hexyl, heptyl, octyl, decyl, decenyl, dodecyl, tetradecyl, hexadecyl, hexadecenyl, octadecyl, octadecenyl, eicosyl, docosyl and cyclohexyl. Specified values of X as an aliphatic hydrocarbon radical are octenyl, decenyl and the C1-C10, C12, C14, C16, C18 and C20 alkyl radicals. Specified values of X as a metal are lithium, sodium, potassium, copper, silver, magnesium, calcium, zinc, strontium, cadmium, barium, aluminium, tin, antimony and lead.  A number of compounds of the above formula are specified.  The salts may be used to thicken lubricating oils to greases.  In examples: (1) monomethyl terephthalate, octadecyl amine, triethylamine and toluene were mixed to form a solution, phosphorus trichloride was added and the mixture refluxed, the methyl N-octadecyl terephthalamate being recovered by known methods; (2) as in (1) but potassium methyl terephthalate was used and a second stage added to the reaction wherein the toluene was replaced by xylene which gives a higher reflux temperature; (3) the sodium and barium salts of N-octadecyl terephthalamic acid were prepared by heating methyl N - octadecyl terephthalamate with sodium hydroxide or barium hydroxide.  A table is given showing the interatomic distances of these salts as determined by X-ray diffraction.

Abstract: 682,805. Radio receiving circuits. PHILIPS ELECTRICAL INDUSTRIES, Ltd. June 14, 1950 [June 17, 1949], No. 14884/50. Class 40 (v). In a radio receiver provided with automatic volume control (A.V.C.) and a tuning-indicator tube of the electron-ray type including two separate amplifier sections, the anode potential of one amplifier section is derived from the screen circuit of a valve in the main signal channel and which is subject to A.V.C. The receiver comprises an I.F. amplifier 4 and diode detector 11; delayed A.V.C. for earlier stages (not shown) is derived from a diode portion 16 of the valve 4 which is coupled to the primary of I.F. transformer 9, being taken off over resistance 19 and condenser 20. The valve 4 is provided with a series screen resistance 33 and derives undelayed A.V.C. from the detector 11, its grid being connected over a filter network 21, 22 to a tap on the detector load resistance 13. The tuning-indicator tube 23 comprises a target 30 and two separate deflection electrodes 28, 29, respectively, connected to the anodes 27, 26 of a pair of triodes possessing a control grid 25 in common, being controlled. by the undelayed A.V.C. potential across condenser 22. The anode 26 is connected via resistance 31 to the H.T.+ line, the potential of the corresponding deflection electrode 29 being proportional to signal strength, in the normal way. The anode 27, however, is connected by resistance 32 to the screen of the valve 4 so that the potential of the second deflection electrode 28 is low save when the valve 4 is biased well back, i.e. on strong signals. In this way the electron beam controlled by electrode 28 provides good indication of tuning even when the signal is sufficiently strong to deflect fully the beam controlled by electrode 29. A modification giving an increased range of control comprises the connection of a resistance 35 between the anode 27 and ground.
