Title: Motordriven tuning apparatus
IPC: H03J7/30
Filed: 1973-05-11
Abstract: 1413585 Automatic control of tuning R C A CORPORATION 11 May 1973 [15 May 1972] 22562/73 Heading G3N [Also in Division H3] A motor driven tuning apparatus which can be programmed to pass by selected channels comprises a first rotary switch 103 having stator terminals each connected to a respective one of a plurality of adjustable potentials 115, 117 and having a rotor terminal R to provide a selected one of the adjustable potential to an electrically tuned tuner, 119, 123, a motor 101 to drive the first rotary switch 103 so that the stators are contacted in sequence, a motor control circuit 109 to activate or inactivate the motor, the motor control circuit 109 being arranged to activate the motor when provided with an over-ride signal and being otherwise responsive to operator control, and a voltage sensing arrangement 155 responsive to each selected adjustable potential when it is within a certain portion of its adjustment range to provide the over-ride signal. In the television tuner shown by pressing time button 113 a transistor 181 conducts and operates a bi-stable circuit 111 to make 171 off and 177 on. This starts the motor 101 which drives the gauged rotary switches 102-105 until the button 113 is released. The motor 101 continues to be driven after the button has been released until the rotor R of switch 102 contacts a channel contact 3-13, A-H which connects a +6V supply via diode 189 to turn on the transistor 171 and turn off the transistor 177 of the bi-stable circuit 111. A channel position can be set to be over-ridden by setting the potentiometer, such as 117, to provide a tuning voltage, via transistors 131, 133 and 149 below a certain value so that a transistor 155 is made non conductive. This makes a transistor 163 on and a transistor 157 off so that channel indicator lamp 119 is not lit and a diode 169 conducts to maintain the bi-stable circuit transistors 171 and 177 off and on so that the tuning motor 101 continues to drive the channel reflector switches 102-105 until the rotor R of the switch 102 contacts a stator contact corresponding to a non over-ridden channel position. When a tuning position is selected the tuning voltage from the selected potentiometer 115, 117 is fed to the VHF tuner 123 or UHF tuner 119 which is supplied with power via rotary contact R of switch 105. Also the selected tuning potential is fed via 131 and 133 to a channel indicator meter 135 and via 149 to turn transistors 155 and 157 on and 163 off so that the selected channel lamp 119 is lit. When the UHF tuner 119 is selected the VHF tuner 123 operates as an IF amplifier. In order to enable the higher VHF channels 7-13 to be over-ridden a +B potential from the rotar R of switch 105 turns on a transistor 147 so as to enable the potential at the input of the transistor 155 to be adjusted low enough by the potentiometers 115 corresponding to the higher VHF channels to provide the override operation.
Patent GB-993586-A (GB)
Title: Preparation of alkyl aromatic hydrocarbons
IPC: C07C2/72
Filed: 1963-06-06
Abstract: Alkyl aromatic hydrocarbons are made by telomerizing ethylene on a "benzenoid" hydrocarbon at 50-80 DEG  C. in the presence of a catalyst prepared by combining a non-aromatic tertiary amine with a compound of formula LiR in which R is alkyl, cycloalkyl, phenyl, alkylphenyl, phenylalkyl or alkenyl radical containing 1-30 C. Benzenoid is defined as a compound having at least one benzene nucleous which may be substituted and/or which may be fused to an alicyclic ring.  Specified benzenoid hydrocarbons are xylenes, ethylbenzene, n-propylbenzene, i-propylbenzene, trimethylbenzenes, n-, sec.- and tert.-butylbenzenes, tetrahydronaphthalene and cyclohexylbenzene.  If the starting aromatic contains a saturated hydrocarbon group having a hydrogen atom attached to the a -C atom, reaction will take place in the a -position by telomerization.  If there are two a -hydrogens only one site is reactive in practice. When there is no a -hydrogen reaction occurs at the aromatic nucleus and growth therefrom ensues. Examples are given which describe the synthesis of C3-C17 alkyl aromatics.ALSO:A catalyst is prepared by combining a non-aromatic tertiary amine with a compound of formula NiR in which R is a hydrocarbon radical having 1-30 C selected from alkyl, cycloalkyl, phenyl, alkylphenyl or alkenyl radical. Additionally the catalyst may contain sodium alkyls.  Preferred tertiary amines are triethylene diamine, 1:4-ethylenepiperidine, and tri-lower aliphatic amines.

Filed: 1921-08-26
Abstract: 189,230. Hobbs, H. T., and Knowles, W. Aug. 26, 1921. Drinking-vessels and cylindrical articles, cleaning.-A machine for washing tumblers and like vessels, of the kind in which reciprocation of the vessel to be cleaned causes rotation of a cleaning brush and relative reciprocation between the brush and the vessel, comprises a base-plate a on which is mounted a footstep bearing b for an archimedian screw c, with which a perforated platform d is adapted to engage, the platform being kept in its uppermost position by a spring e. The brush f is mounted on the end of the archimedian screw and adapted to project inside the vessel to be cleaned which rests inverted upon the platform d, the whole being immersed in water. Reciprocation of the vessel and platform will cause rotation of the brush, and also relative reciprocation between brush and vessel thus cleaning it completely. The footstep bearing b is adjustable and a bearing ring g takes the upward thrust of the spring.

Title: Improvements in the treatment of textiles
IPC: D06M13/332
Filed: 1935-08-17
Abstract: Cellulosic textile materials are treated, prior to or during dyeing, with a polyamine obtainable by reacting a halogenalkylamine with a nontertiary organic base which is free from aliphatic --C = C-- double linkages and contains in the molecule at least 6 carbon atoms. The polyamines may be used in the form of their salts.  In the case of artificial cellulosic textile materials, the polyamine or salt thereof may be applied in the spinning bath.  If the polyamine is insufficiently soluble in water it may be replaced by a derivative thereof obtained by reaction with ethylene oxide or by hydroxy-alkylation, per-alkylation or sulphonation.  The treatment improves the softness and water-repelling qualities of the material and its behaviour toward dyestuffs.  Specified halogen-alkylamines are chlorethylamine, methylchlorethylamine, diethylchlorethylamine, di-(b -chlorethyl)amine, 1-chloro-2-aminopropane, laurylchlorethylamine and the corresponding bromine compounds. Specified non - tertiary organic bases are primary and secondary alkylamines, cycloalkylamines, aralkylamines, arylamines, heterocyclic amines and secondary heterocyclic bases, e.g. hexylamine, methylhexylamine, decylamine, dodecylamine, octodecylamine, b  - oxyethyllaurylamine, cyclohexylamine, methylcyclohexylamine, decahydronaphthylamines, benzylamine, aniline, methylaniline, toluidines, naphthylamines, C-methylpiperidines and decahydroquinolines.  The following examples are specified: (1) viscose artificial silk or cotton is treated for \ba1/4\be hour with an aqueous solution at 50 DEG  C. of N-stearyl-N<1>-diethyl - ethylenediamine monohydrochloride (obtainable by reaction of stearylamine with diethylchlorethylamine for 1 hour at 120--130 DEG C.), squeezed and dried; the treated material has affinity for acid wool dyestuffs and a soft, supple feed and is water-repelling; the said compound may be applied in the spinning bath for the artificial silk; (2) cotton or copper artificial silk is similarly treated with an aqueous solution of the product obtainable by reaction of stearylamine with diethylchlorethylamine hydrochloride. Specifications 361,261, 362,061, and 372,325 are referred to.  The Provisional Specification describes also the use of the product obtainable by heating stearylamine with chlorethylamine hydrochloride in water or alcohol.
