Title: Stringed musical instrument
IPC: G10D3/08
Filed: 1944-12-12
Abstract: 603,153. Stringed musical instruments. McBRIDE, J. W. Dec. 12, 1944, No. 24923. [Class 88 (ii)] In a stringed musical instrument such as a guitar, mandolin or violin cam means are provided for selectively moving frets into and out of contact with the strings to determine the length of the vibrating string portions. In a guitar, the frets are arranged under the strings 5, 6, 7, 8 in four series, Fig. 1. The frets are guided for movement into and out of engagement with the strings by guide plates 21, 22, Fig. 9, and are normally held out of contact with the strings by springs 41 engaging the plate 21 and a pin 40 on each fret. The frets of each series are urged towards the corresponding string by means of cam rods 54 provided with steep cam surfaces with the cam crests corresponding to the respective frets falling in a helical curve. Alternatively a continuous helical crest may be provided on each rod. The cam surfaces are made steep so that the frets will contact the strings with sufficient speed to cause them to vibrate without the aid of a plectrum. The sounds may be amplified electrically by apparatus including a pick-up P and mechanism for the control of volume and tone at 15 and 16 respectively. The cam rods 54 are controlled by keys 60 arranged to slide in a direction transverse to the strings. A key 60, when pressed, rotates the cam rod 54 by means of a spiral spring connection 56, Fig. 3, which returns the key to normal when pressure is released. Only'one of the four spiral springs is shown in Fig. 3. To facilitate setting of the keys 60, a lens 80 is provided through which transverse graduation markings on the keys can be viewed. In a modification, Figs. 13, 16, the rotatable cam rods are replaced by longitudinally movable rods 122 carrying cams such as 153. Each rod 122 can be pressed against the action of a spring 142 to bring the desired fret such as 150 into contact with the corresponding string 96. A key 148 is provided for each rod 122 and the setting can be viewed through a cylindrical lens 156. In another modification, the frets take the special form shown in Fig. 30. Frets 179 are supported end to end in a series under each string 165, Fig. 21. A cylindrical projection 201 fits into a corresponding socket 202- on the adjacent fret to form a hinge. The frets are restricted against lateral movement by the engagement of flanges 186 with the sides of a slot in the body of the instrument and they normally rest on plates 195 spaced sufficiently apart to pass the narrow extension 199. Upward movement of the frets is limited by plates 188. The arcuate pointer edges 200 of the projections 199 come into engagement with the helical like crests 206 on the cam rods 205 as the rods rotate. As a cam is rotated the frets of the series are in turn raised to contact the string and are then rolled to transfer the contact along the string and thereby produce a glissando effect. In this arrangement the keys 222 rotate the cam rods through racks 229 and pinions 230 against the action of springs 234.

Title: Alkylene imine copolymerization products and process of making same
IPC: C08G73/04
Filed: 1962-07-02
Abstract: Alkylene imines are copolymerized with 0.05-10 mole per cent of alkyl halohydrins, or epihalohydrins, or polyepoxides, or compounds convertible into these under the reaction conditions. These compounds must have more than one halohydrin or epoxy group present or formed during the reaction, and at least one halogen atom which will react with the alkylene imine, or an acid may be provided for the latter purpose.  Suitable compounds include, among others listed, epichlorhydrin, 1,2-halo-3-hydroxy propane, 2,3; 4,5 - diepoxy - 1,6 - dichlorohexane - 1,2 - epoxy - 3 - hydroxy - 4 - chloro - butane, and 2 - hydroxy - 1,3 - propane disulphuric acid ester, and the diepoxides butadiene diepoxide, vinyl cyclohexene diepoxide and N,N1-bis-(2,3-epoxy-propyl)-urea, in conjunction with an acid.  The initial solution of the reactants should contain not more than 45% by weight of the imine.  Any solvent for the monomers which is insert towards them is suitable, though water is preferred.  The products are cationic, many-branched, polyamines giving stable water solutions not degenerating on storing. Spontaneous polymerization does not occur below about 40 DEG  C., so that the imine and comonomer may be mixed in the reaction vessel, or immediately before entering it, then heated to polymerization temperature in a "batch reaction," or may be run, as a "continuous batch," into a mixture already at polymerization temperature, which the heat of polymerization helps to maintain. Examples describe the reactions of ethylene imine with 0.7 to 1.4 mole per cent of epichlorhydrin, and compares the products with acid-catalyzed polyimines of the prior art.  Also described are reactions of 2-methyl ethylene imine, N-methyl ethylene imine, 2-ethyl ethylene imine, and N-n-butylethylene imine with epichlorhydrin in water, methanol, or isobutanol, or mixtures of methanol, isobutanol or benzene with water, and the reactions of ethylene imine with vinyl cyclohexene diepoxide and limonene diepoxide in hydrochloric acid.ALSO:Paper may be treated with a resin obtained by copolymerizing an alkyline imine with .05-10 mol per cent of an alkyl halohydrin or epihalohydrin (see Division C3).  Addition of the resin improves the freeness and drainage, and the flocculation and filler retention of paper pulp slurries, and the wet strength and drying properties of sheet paper, and improves the adhesion of plastic films and of inks thereto.  In an Example paper hand sheets are prepared containing .1 or .5 weight per cent of various ethylene imine-epichlorhydrin cocondensates.
