Title: Push-button set for use in a radio receiver
IPC: H03J5/12
Filed: 1974-04-24
Abstract: 1470842 Linkwork; cams PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 24 April 1974 [27 April 1973] 17888/74 Addition to 1253438 Heading F2K [Also in Divisions E2 and H3] In a pushbutton arrangement for tuning a radio in which each pushbutton 1, Fig. 1, is capable of actuating two drive rods 9, 11; 13, 15 which in turn drive a common tuning mechanism, each drive rod 9, 11; 13, 15 is actuable alternately by a gear 31 which moves with the associated pushbutton and is coupled to a drive gear 33 rotated on depression of the button by a drive pawl 41, 71, Fig. 4 so that a reciprocating bolt 27 driven by the gear 31 first engages one and then the other of the drive rods 9, 11; 13, 15 during successive depressions of the button 1, The drive pawl 41, 71 has a guide slot 77 between opposite sides of which the drive gear 33 can rotate only in the region of a recess 83 in one of the sides. Two fulcrum 87, 117 selectively co-operate with a frame 7 and a spring 95 engaging the drive pawl 71 so as to urge the drive pawl 71 about fulcrum 101, Fig. 4 to press one side 79 of the slot against the drive gear 33 or to urge the drive pawl about fulcrum 117, Fig. 6 to press the other side 81 of the slot against the drive gear 33. When a tuning cam associated with a drive rod such as 15 is to be repositioned the pushbutton 1 is pulled out and the bolt 27 slides the drive rod 13 outwardly with respect to the drive rod 15 so as to release the tuning cam. Also when the button 1 is pulled out a catch 111 connected to the pushbutton rod 3 engages a projection 113 of the drive pawl 71 and moves the drive pawl 71 from the depressed position shown in Fig. 4 to an outward position, Fig. 6 where the spring 95 biases the drive pawl 71 about the fulcrum 117 so that the drive gear 33 engages the side 81 of the slot 77. When the button is now pressed in the drive gear 33 engages end 109 of the slot 77 and moves the drive pawl 71 back to the position of Fig. 4. The drive rod 13 slides back to reset the tuning cam to the selected tuning position. The co-operation of the gear 33 with the sides of the slot 77 and the operation of the drive pawl 71 ensure that during resetting of a preset position the drive rod 13 is moved through the same amount and returned to the same position relative to the drive rod 15. This eliminates errors 61<SP>1</SP> in repositioning the rod 13 relative to the rod 15 during returning. In a modified bolt (127, Figs. 7-9, not shown) the gear (131) has teeth (131a-131c) which continuously engage cams (147) on the bolt (147) so that the bolt can only be displaced by rotation of the drive gear (33) to avoid shifting of the bolt due to vibration.

Title: Improvements in the manufacture and production of highly concentrated nitric acid
IPC: C01B21/44
Filed: 1928-06-21
Abstract: 321,728. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). June 21, 1928. Nitric acid.-The production of concentrated nitric acid by the action of oxygen upon liquid or vaporous nitrogen peroxide or other nitrogen oxides in presence of dilute nitric acid is carried out in a fractionating column charged with fillers. Pressures up to about 10 atmospheres may be used. The temperature is regulated so as to be about 20-25‹ C. in the upper part and 100-125‹ C. in the lower part. In the upper part of the column at temperatures of 20-25‹ C. the vapour phase consists mainly of nitrogen peroxide, in the middle parts at temperatures of 25-84‹ C. it consists of a mixture of nitrogen peroxide and nitric acid, at 85-90‹ C. of practically pure nitric acid vapours which may be withdrawn and condensed, and at 90-125‹ C. of nitric acid and water vapour. The nitric acid vapours withdrawn at 88‹ C. may be used to expel nitrogen oxides from already condensed nitric acid. The column may be heated by passing into it, vapours from the nitric acid of lowest vapour pressure and of boiling-point of about 123‹ C. passing from the base of the column. Dilute nitric acid for use in the process may be obtained by absorbing in water the nitrous gases obtaised by the combustion of ammonia.

Patent GB-867279-A (GB)
Title: Fluorocarbon substituted triazines and condensates thereof
IPC: C08G12/30
Filed: 1958-06-06
Abstract: Water- and oil-resistant resinous compounds are prepared by heating together formaldehyde and a compound of formula: <FORM:0867279/IV (a)/1> where X and Y are amino or hydrazino radicals, Rf is a perfluorinated alkyl radical of 4-12 carbon atoms, and Z is a group of formula: <FORM:0867279/IV (a)/2> or <FORM:0867279/IV (a)/3> where n is 1-12, m is 0-12, q is 1-13, and R is hydrogen or an alkyl radical of 1-6 carbon atoms.  The resinous products are thermosetting, and can be cast in thin sheets or films, or can be used as coatings, e.g. on fibrous materials such as paper and textiles.  It is stated that in place of formaldehyde, there may be used paraformaldehyde, hexamethylene tetramine, acetaldehyde or furfural.  The monomeric triazine derivatives may also be employed as curing agents for epoxy-resins, such as bisphenol A-epichlorhydrin resins (Examples 3, 4 and 11).  The above monomeric triazine derivatives, or their formaldehyde condensation products, may be used as hardening agents for alkyl-ureaformaldehyde and melamine-formaldehyde resins.ALSO:The invention comprises compounds of the formula:  <FORM:0867279/IV (b)/1> where X and Y are amino or hydrazino radicals, Rf is a perfluoroalkyl radical containing 4-12 carbon atoms, and Z is -SO2NH(CH2)n NH-, -SO2NR-, -CONH(CH2)mNH-, -CONH-, -(CH2)qO- or -(CH2)qNH-, where n is 1-12, m is 0-12, q is 1-13 and R is hydrogen or C1-6 alkyl.  These compounds are prepared by normal condensation processes between suitable fluorinated compounds and mono-halogenated triazine derivatives, or between halogen derivatives of the fluorinated compound and a suitable triazine derivative.  Thus 6-chloro-2,4-diaminotriazine may be condensed with RfCONHNH2 (obtained from RfCOF and hydrazine), or perfluoroalkyl-alkanols or alkylamines; or with alkylene diamines, to form 2,4-diamino-6-aminoalkylamino triazines, which are condensed with RfSO2Cl or perfluoroinated carboxylic acid esters or halides; RfSO2NHR can be condensed with cyanuric chloride, and the product with ammonia or hydrazine.  Compounds containing the (CH2)q radical can be prepared by reacting RfSO2Cl or RfI with a distally unsaturated alkenol, or alkenoic acid or ester, followed by reductive dehydrohalogenation and, if necessary, saponification; the acids obtained can be converted into the amides (via the chlorides), which are reduced to amines; or the esters can be reduced to alcohols; these alcohols and amines are then used in condensation reactions with halogenated triazines.  N-Propyl-perfluoro octane sulphonamide is pared by reacting C3H7NH2 with C8F17CO2F, and is converted into its sodio derivative by reaction with CH3ONa in methanol.
