Filed: 1929-09-19
Abstract: 339,690. Magat, E., and Savage, H., (trading as Magat & Savage, E.). March 25, 1929, [Convention date]. Keyboard stringed instruments bridges; tuning - devices. - A stringed instrument comprises keys 10, Fig. 1, carrying strips of cardboard 12, Fig. 2, which " stop " the strings from underneath. The keys simultaneously operate a vibrato device, comprising a padded pivoted bar 20 adjustably weighted at 24 and resting on the strings near one end, by means of an escapement pawl 13 which raises and lets fall a longitudinal bar 16 pivoted at 17. The bar 16 by a lug 18 similarly actuates the vibrato bar 20 through a screw 19. The vibrato bar may be put out of action when desired by a cam 26 operated by a button 28. The strings may be bowed by hand, or plucked by the fingers. Or the keys 10 may actuate a hammer or hammers 30, Fig. 4, by means of the bar 16 which is provided with another lug 29 for the purpose. The hammers may be put out of action when desired, by a cam 32 operated by a button 34. Alternatively or simultaneously the strings may be sounded by a spring-mounted plectrum 39 (or plectra) operated by pressure of the fingers. The key-levers 9 may be gapped so as to act at 12 on certain strings only, to enable chords to be produced (Fig. 9, not shown). More than one keyboard may be employed (Fig. 10, not shown). It is stated that the bar 20 causes the tension of the strings to be unaffected by operation of the key-levers (Fig. 5, not shown). The strings are fine-tuned by pressure of screws 8, Fig. 8. Fig. 11 shows a bridge 4 with an arm under which the strings pass. Fig. 12 shows an arrangement with two sound boards or boxes, the keylevers 9 pressing the strings against frets on the under side of the upper box.

Title: Improvements in or relating to the production of resin-bonded laminated structures
Inventor: BOSWORTH PETER
IPC: C08J5/24
Filed: 1960-08-17
Abstract: A process for the production of reinforced synthetic resin articles comprises impregnating or coating a reinforcement material with a fusible resinous composition, interleaving the coated or impregnated reinforcement so produced with a reinforcement material previously coated or impregnated with a second fusible resinous composition capable of reacting with the first resinous composition so as to cure it to a substantially thermoset condition and subjecting the assembly so produced to the action of heat and pressure.  The reinforcement may be in the form of continuous filaments or threads of spun fibre, woven or knitted cloth, felt, mat, or paper; it may be of glass, cotton, asbestos, polyamide or other fibre or filament-forming material.  Specified combinations of resinous compositions are (i) an epoxide resin prepared by reacting a phenolic novolak with epichlorhydrin, and an aniline resin prepared by reacting aniline with formaldehyde, (ii) an epoxide resin as in (i) above and a resinous composition comprising hexahydrophthalic anhydride, polyvinyl acetate and acetone, (iii) an epoxide resin as in (i) above and a resinous adduct of an epoxide resin and diethylamine prepared by the method described in Specification 832,189, (iv) urea-aldehyde resins and phenolic novolak resins, (v) phenolic novolak resins and phenolic resole resins.  Either or both of the resinous compositions may include fillers such as chalk, slate flour, metal powders, starch, wood flour, plasticizers such as polyoxyalkylene polysulphide rubber, dioctyl phthalate and glycol, accelerators, retarders, anti-oxidants, fungicides, dyes and pigments.  Woven or knitted fabrics may be impregnated by passage through a bath containing a solution of resinous composition in a volatile solvent, then through nip rollers to control the resin content of the fabric.  The resinous composition may also be applied in molten state.  Filaments or rovings may be similarly impregnated followed by passage through an orifice to control resin content. Laminates in the form of flat sheets or shaped articles may be produced by assembling alternate piles of the two impregnated reinforcements and casing the resultant assembly in a suitable mould under heat and pressure.  Impregnated rovings may be wound on to a mandrel to form a pipe or tube. Comminuted rovings, mixed in appropriate proportions may be employed for production of mouldings by forming them to a desired shape in a matched mould under heat and pressure.

Abstract: 1326290 Printing - machines NORTH AMERICAN ROCKWELL CORP 17 June 1971 [26 Aug 1970] 28543/71 Heading B6C Sheets are transferred in turn from a registered position on a table 11, Figs. 3 and 3a, against stops 13 to the grippers 41, Fig. 4, of the impression-cylinder 40 of a rotary printing- machine by an oscillating transfer mechanism 30 which includes a plurality of gripper pads 51, 52, Figs. 3, 3a, 10, 10b, mounted on a pad bar 50 which is centrally fixed with respect to a cylinder 31 of the mechanism 30, and which is attached at its ends to the cylinder by means which allow a small amount of movement peripherally of the cylinder. The pads have rough surfaces 57 which co-operate with gripper fingers 61 to grip the sheets. The peripheral movement of the ends of the bar cause bowing of the bar and is produced during the oscillating movement of the mechanism 30 by stationary cams 100 acting on rollers 105 on arms 111. In operation, a sheet 15 having a straight leading edge 16, Fig. 10, is picked up by the pads 51, 52 and fingers 61 when the bar 50 is bowed by movement of its ends in the direction of sheet feed. During movement of the sheet to the transfer position of Fig. 4, the cams 100 cause the bar 50 to be first straightened and then bowed in the opposite direction so that the leading edge 16 becomes bowed, Fig. 10b, so as to counteract fan-out The cams are adjustable by knobs 174 about pivots 160 so as to produce the desired degree of bowing. Alternatively, the bar 50 may be straight in either the picking up or the transfer position and bowed only in one direction during its movement. The bar 50 may be rigidly mounted at its ends and movable at its centre. The bar 50 may be omitted and the pads 51, 52 separately mounted for individual peripheral movement so that the line drawn through them is bowed or straightened.

Abstract: 710,250. Automatic guns. VERWALTUNGSGES DER WERKZEUGMASCHINENFABRIK OERLIKON. Nov. 19, 1952 [Nov. 21, 1951], No. 29262/52. Class 92(2) A gun is fitted with a temperature-sensitive detector means 3 operatively connected to interrupting means on the gun in such way that firing is interrupted when the heated part, upon which the means 3 is arranged, reaches a predetermined temperature. In the construction shown in Fig. 1 the means 3 comprises a bimetallic strip having its fixed end connected to a lead 8 and its free end adapted to touch contacts on leads 10, 21. With a tumbler switch 14 in the position shown the firing mechanism 17 on the gun is actuated by closing a switch 18 in circuit with a battery 16. When the barrel 2 becomes heated to the predetermined temperature the bimetallic strip closes a circuit 8, 9, 13, 12, 10 to energize an electro-magnet 11 which opens the switch 14 and thereby interrupts the firing. When the barrel cools sufficiently the bimetallic strip moves.to close the circuit 8, 9, 13, 20, 21 to energize a coil 19 serving to close the switch and permit firing. In a modification the tumbler is directly actuated by the bimetallic strip, and in another modification the device 3 comprises a thermocouple to bring the electro-magnets into operation via a voltmeter with contacts. In Fig. 3 the change of temperature in the barrel 2 results in the change of resistance in a detector 31 arranged in a bridge circuit, thus causing a coil 38 to swing  a pointer 37 of a voltmeter into contact with one or the other of two terminals 50, 41. These are arranged as shown in circuit with electro-magnets 42, 43 serving to actuate a tumbler switch 44 arranged in the firing circuit. The electro-magnets may alternatively be used to operate locking members serving to block the movements of the breechblock.

Abstract: 692,473. Velocity-modulated tubes. KONIG, H. Nov. 16, 1948 [Nov. 20, 1947], No. 29761/48. Class 39(i). In a velocity-modulated tube having " regions " comprising at least one input resonator, one drift space and one output resonator limited by grids to which are applied d.c. voltages or a.c. voltages of a frequency much below that of the highfrequency signal to be modulated, the applied voltages are arranged to produce at least two unidirectional charges of field intensity to improve the energy transfer and so increase the amplification. In. the Figure, the tube comprises a cathode 1, an input resonator 7 with coupling loop 9 and grids 2, 3, a drift tube 13, an output resonator 8 with coupling loop 10 and grids 4, 5, and an anode 6. The resonators 7, 8 and the drift tube 13 are each in two parts, capacity-coupled at 12 and 14, respectively, so that the required potential differences are created between the grids 2 to 5 by connecting the walls of the resonators to tappings on a battery 11. The application of these potentials permits the lengths of the resonators to be selected so that their transit angle is an even multiple of #. In a tube having more than three regions, the transit angle in a resonator having no field charge would be an odd multiple of #. The drift space may be subdivided by further grids to which potentials may be applied to produce unidirectional field changes.
