Patent GB-631367-A (GB)
Title: Amidation of esters
IPC: C07C233/00
Filed: 1947-06-09
Abstract: Polyamides are prepared by the self-condensation of amino-acid esters, e.g. glycine methyl ester, or the condensation of a polyvalent amine, e.g. hexamethylenediamine, with a polyester, e.g. dimethyl adipate; the reaction is catalyzed by an alkali metal alcoholoxide or an alkali metal compound yielding an alcoholoxide on treatment with an alcohol, e.g. sodamide. Specification 558,893 is referred to.ALSO:Amides are prepared by the interaction of esters and ammonia or amines containing replaceable hydrogen in the presence of an alkali metal alcoholoxide or an alkali metal compound which will generate an alcoholoxide on contact with an alcohol.  Preferably, the amine is an aminoalcohol, e.g. monoethanolamine, the catalyst an alkali metal aminoethoxide, and the ester a glyceride fat, a saponifiable wax, sperm oil or spermaceti.  Many other suitable esters are specified, including esters of monobasic, polybasic, and phenolic acids, ketoacids, drying oil acids, resin acids, and Diels-Alder adducts.  Amino-acid esters, e.g. glycine ester, may be self-condensed.  The acids giving suitable esters may be esterified with e.g. alkanols and polyhydric, cyclic and heterocyclic alcohols and sterols.  Suitable catalysts mentioned are alkoxides, amides, e.g. sodamide, organo-metallic compounds of alkali metals, and concentrated aqueous alkali hydroxide; the presence of small quantities of water is permissible.  A solvent may be employed, e.g. an excess liquid ammonia when ammonia is one of the reactants.  Many suitable amines are specified, e.g. aniline, isopropanolamines and ethylene diamine.  Esters and amines must be free of groups capable of destroying the catalyst; they may contain other groups such as alkoxy and chlorine, as in p-chlorobenzoic esters.  In the examples (1, 3, 4, 6 and 7), monoethanolamine containing a small quantity of sodium is treated with ethyl benzoate, rape oil, sperm oil, hydrogenated castor oil and carnauba wax, respectively, to give the corresponding monoethanolamides, (2) methyl oleate is heated with methanolic ammonia containing some sodium methoxide to give the amide of oleic acid, and (5) methyl ricinoleate is heated with cyclohexylamine in methanol containing some sodium methoxide to give ricinoleic cyclohexylamide.  Specification 558,893 is referred to.

Abstract: 1385845 Collecting and stacking rod-like articles; conveyers AMF Inc 29 March 1973 [13 April 1972] 15273/73 Headings B8A and B8C In a method for collecting and stacking rodlike articles, such as cigarettes S, from a continuous flow of said articles aligned side-by-side along a feed path, the flow of cigarettes is cyclically switched, according to predetermined frequencies, subsequently to each one of at least two collecting stations, in which station the cigarettes are collected in a row aligned side-by-side up to a predetermined number, after which the formed row is transferred into a collecting tray while the continuous flow of cigarettes is switched to another one of the collecting stations to form another row to be thereafter transferred into the tray stacking over the preceding row. As shown, cigarettes, aligned side-by-side, are carried on a fluted drum 1 which rotates in the direction F about its own axis to supply a predetermined number of cigarettes alternately to upper and lower conveyer belts 2, 3 through the intermediary of a deflector 4 which oscillates around a shaft 5 in accordance, e.g. with a commutating control, not shown. The deflector 4, of rectangular section, is partially open at the base to permit rotation of the drum 1 and provide side wings 204 which supportingly receive the ends of cigarettes S which project from the sides of the drum 1, the time taken for the shift of the deflector 4 from one conveyer to the other, being less than one step of drum rotation. The belts 2, 3 driven respectively over rollers 102, 202, 302 and 103, 203, 303, 403, pass through respective slots 106, 206 in a stop plate 6, a tray 7, of a width to accommodate a row of aligned, side-by-side, cigarettes, for which the operation of the deflector 4 is pre-arranged, being located adjacent one side of the belts 2, 3. Pusher elements 8, 9 associated respectively with the belts 2, 3 transfer the rows of cigarettes into the tray 7. The two pusher elements may be replaced by a single pusher movable vertically and horizontally.

Abstract: 392,363. Delivering liquid or gaseous disinfectants. SEITZ-WERKE GES., Planigerstrasse, Bad Kreuznach, Rhineland, Germany. June 4, 1932, No. 15800. Convention date, June 22, 1931. [Class 81 (i).] A device for introducing small measured quantities of liquid or gas into bottles &c. for sterilizing comprises a measuring chamber 12 supplied with fluid under pressure from a flexible pipe, through a chamber 2 closed on the rear side by a flexible membrane 3 which is moved by a trigger 19 to close the inlet and open an outlet valve 6, the fluid being then forcibly delivered through an outlet pipe 15. As shown, the flexible supply pipe is connected to the device at 1 and the fluid passes through the chamber 2, the hollow stem 4 of the outlet valve, and a side opening 11 to the measuring chamber which is closed at the top. On pressing the trigger 19 a bolt 2.0 moves the membrane 3 to close the bore of the valve stem 4 and open the valve 6 against a spring 13, the fluid under pressure then passing through another side opening in the valve stem to the pipe 15, which is provided with a rubber pad 16, to form a seal with the mouth of the bottle. In measuring volatile liquids and vapours such as sulphur dioxide the air is first removed from the measuring chamber by holding it inverted, loosening a vent screw 17 and supplying the vapour to displace the air. In the case of liquids the air compressed above the liquid in the measuring chamber forces the liquid out. A spring 22 returns the trigger to the filling position. The device can be attached to bottlefilling apparatus and the valves operated automatically.

Patent GB-1165531-A (GB)
Title: Pulse Radar
IPC: G01S13/24
Filed: 1962-04-25
Abstract: 1,165,531. Automatic tuning radio receivers; pulse radar. NETHERLANDS APPLIED SCIENTIFIC RESEARCH FOR STATE DEFENCE. 25 April, 1962 [26 April, 1961], No. 15849/62. Headings H3Q and H4D. In a pulse radar transmitter/receiver installation the carrier frequency of the transmitted pulses is varied from pulse to pulse to overcome jamming, the frequency of the local oscillator being swept through a sufficient range within the duration of each pulse to ensure that at some instant during the pulse the difference between the pulse carrier frequency and the local oscillator frequency will be equal to the frequency of the I.F. amplifier. As shown, an antenna 6 is coupled through means 11 to a transmitter tube K 2 , the local oscillator K 1 , e.g. a klystron, being coupled to the antenna through waveguides 12, 13. The outputs from K 1 , K 2  are also connected through a mixing crystal 7 to an I.F. amplifier 8. The frequency of K 1  depends upon the voltage applied to its reflector electrode, this voltage having two components, viz the contant voltage of a source 5 and an added voltage derived from condenser C. The condenser is charged through resistors R 1 , R 2  and a diode V 5 . Tubes V 42 , V 52  form a flip-flop and depending on its state the charging circuit of condenser C is switched on or off. If tube V 42  is conductive and tubes V 52 , V 32  are non-conductive the condenser may be charged, the condenser voltage being fed to the source 5 through a cathode follower V 22 . When the condenser voltage attains a certain value the local oscillator K 1  produces a frequency difference with that of the tube K 2  such that the I.F. amplifier 8 generates a signal causing the flip-flop to change over. The non-conductive tube 42 causes the resistance R 6  to carry no current so that the anode voltage of V 32  decreases. Thus providing the value of R 2  is suitably chosen the charging of the condenser C is terminated. The condenser retains its charge during the remainder of the transmitter pulse. Just before the next pulse of the transmitter tube K 2  the condenser is discharged by applying a pulse at A to render tube V 12  conductive, whereby the system is ready to transmit the next pulse having a carrier frequency different from the preceding pulse. The pulse at A may be derived from the forward edge of the transmitter pulse.
