Abstract: 532,557. Riveting. FRANKFURTER MASCHINENBAU-AKT.-GES. VORM. POKORNY & WITTEKIND. Sept. 7, 1939, No. 25322. Convention date, Sept. 6, 1938. [Class 83 (iv)] A machine for riveting perforated work 77, 78 has an upsetting die 91, with a resiliently mounted centre pin 102 for aligning the perforations, mounted to slide vertically in an adjustable work support 98 and a work clamp 76, with a rivet supply device and a punch 22 for driving a rivet through the perforations, backing it during upsetting, and, if desired, countersinking the plate 77. A hand operated valve 10, during its downward movement, first admits compressed air &c. from a pipe 3 and port 18 to a port 20 thereby moving down a piston 8 and a slide 5, rivet guideway 69, and clamp 76 connected thereto, the rivet 43 falling down the hole vacated by the punch 22 and into jaws 72. The valve then admits air to ports 37, 35 thereby moving a piston 32 to the left and, by means of a toggle 25, 26, forcing down the punch 22. The piston 32 uncovers ports 51, 96 thereby admitting air to a cylinder 48, Fig. 6, the piston of which operates a rivet pick-up 39 to supply rivets to a fixed guideway 41, and also admitting air, via a pipe 94, Fig. 5, to a cylinder 84 thereby moving a piston 83 to the left and, by means of a toggle 80, 81, forcing the die 91 and pin 102 up as shown to upset the rivet. When the valve 10 is returned to the position shown in Fig. 1 by its spring 17, the ports 20 and 37 are opened to exhaust at 12 and the pistons 8, 32 and 83 are returned by springs 9, 34, 97 so that an arm 58 on the guideway 69 strikes a lever 63 on a shaft 62 which it turns, against the action of a spring 65, Fig. 9, to withdraw its arm 64 and allow a spring 57 to move a slide 56. This slide has an inclined slot 66, Fig. 12, so that at each to-and-fro movement one rivet is allowed to pass down the guideway 41 and on to the guideway 69 which, in the normal position, aligns with it. The pick-up 39 and slide 56 can be operated by hand to feed a rivet to the guideway 69 before starting the operation of the machine.

Class 38(3) [Also in Group XXXV] The slip-rings of an induction motor 1 are coupled to a grid-controlled rectifier 3 through a regulating transformer 2 the ratio of which is adjusted by means of a motor-driven governor 4 in such a manner that the anode potential of the rectifier remains constant despite changes in the rotor voltage of the motor. Grid control of the rectifier is effected by a rotary contact device 8 driven by a synchronous motor 5, each grid of the rectifier receiving a positive potential impulse in turn whilst the other grids remain at the negative potential afforded. through a rectifier 7. A torque motor 6 adjusts the device 8 to provide phase shift control of the rectifier. A carbon pile resistor 9 is connected in the circuit of the motor 6 and is initially adjusted by means of a handwheel 11. Further adjustment of the resistor 9 is effected by slide 10 coupled to the governor 4 so that any tendency for the speed of the motor to increase above the value corresponding to the setting of the handwheel is removed by a reduction in of the resistor 9 and adjustment of the motor 6 to retard the firing of the rectifier.

Title: Improvements in the method of feeding sheets to printing, folding and other machines, and apparatus therefor
IPC: B65H9/16
Filed: 1926-10-14
Abstract: 262,729. Spiess, G. Dec. 9, 1925, [Convention date]. Addition to 249,882. Dropping-roller feeds; sheet carriers and forwarders; sheet-registering devices.-In the sheet-feeding mechanism described in the parent Specification in which continuously-moving sheets are aligned laterally by means of inclined rollers 35, Fig. 5, and a side gauge, and longitudinally by means of a front stop 8 carried by an endless belt, the sheets are fed positively during the greater part of their travel from the pile table 12 to the machine 3 but are released for alignment by 'the registering devices just before reaching the machine. The sheets are fed by means of a dropping roller 44 from a table 12 to an endless band 33 co-operating with rollers 39 carried by adjustably-mounted lever arms 38 to forward the sheets to the inclined rollers 35. A driving shaft 46 has eccentrically mounted thereon a gearwheel 47 which is coupled by means of an intermediate gearwheel 50 to a gearwheel 62 connected by a chain 63 to a sprocket wheel on one of the pulleys 37 carrying the band 33, the gearwheel 50 being carried by links 48, 49 pivoted to the shafts of the wheels 47, 62 and the arrangement being such that the sheet is first accelerated and then retarded before reaching the rollers 35. As the sheet passes over the rollers, balls 43 universally mounted in adjustable sockets 64 rest upon it, and the pressure of the balls can be adjusted by means of screw-operated arms 68 connected by springs 66 with pivoted guides 65 for the sockets 64. Means are provided for adjusting the inclination of the rollers 35 and consists in mounting the rollers in a hinged frame 57, 58, Fig. 7, to one side of which is fixed a toothed sector 59 engaged by a pinion 60 for adjusting the frame. A set-screw 61 is provided for fixing the rollers in any desired position. The dropping roller 44 is carried by a bent lever 52, Fig. 10, having at its extremity a screw-adjusted roller 54 engaged by a cam 53 to operate the roller 44.

Title: Mechanical servo amplifier
IPC: G05G19/00
Filed: 1957-08-14
Abstract: 846,766. Cam mechanism; screw-and-nut gearing. CURTISS-WRIGHT CORPORATION. Aug. 14, 1957 [Aug. 20, 1956], No. 25645/57. Class 80 (3). A mechanical servo-mechanism comprises a power input member in the form of a continuously-rotating cam 23, a power output in the form of a longitudinally-movable screw 16 and a control member in the form of a pinion 27 engaging gear-teeth 26 on one nut member 17 of a pair of rotatable nut members'17, 18 co-operating with screw 16. The nuts 17, 18 are centred relative to each other by springs 33, 34 and spaced apart along the screw 16 with a certain amount of clearance between the end walls of fixed casing 15 which supports the shaft 20 of cam 23. If a load is assumed to be acting downwardly on the screw 16 and the nut 17 is free to assume its centred position with respect to nut 18 then the cam 23 will repeatedly engage and lift the nut 17 together with the screw 16 and nut 18 but always reseat the nut 18 on the casing without any resultant movement of the screw. If, however, the nut 17 is rotated in one direction or the other by a control crank 29 to tension the springs 33 or 34 during an interval when it is not engaged by cam 23 then when it is engaged by the cam and lifted the nut 18 will be rotated by the spring to follow-up the rotation of nut 17 and move up or down the screw a proportionate amount. When the nut 18 is again seated the screw and hence the load will have been moved up or down that amount. Further rotary movement of nut 17 will result in similar movement of nut 18. In modified arrangements the reciprocatory power input motion is derived from a waved cam rotating about the screw axis and acting through balls on a complementary waved or flat member which transmits the motion to one of the nut members. A waved cam controlring with balls co-operating with setting member for one of the nuts is also arranged coaxially so that on movement thereof in one direction or the other the one nut is set by the power input device a desired angular amount, the load transferred thereto and the second nut caused to follow-up the first nut by a spring coupling and reseated at a different position axially along the screw. Any other form of reciprocating device may be utilized as the power input member as an alternative to the rotating cam.

IPC: F22B31/00
Filed: 1957-08-16
Abstract: 840,351. Preventing furnace corrosion; carbon monoxide containing gas. ESSO RESEARCH & ENGINEERING CO. July 21, 1958 [Aug. 16, 1957; Jan. 23, 1958], Nos. 25897/57 and 2301/58. Classes 51 (1) and 55 (2). The durpoint of the gaseous combustion products in an oil-fired furnace is raised and the harmful effects of sulphur trioxide avoided by replacing part of the fuel burned by a reducing gas. Sufficient reducing gas, which may be carbon monoxide or a gas containing carbon monoxide, is injected into the combustion zone of the furnace to burn with substantially all the excess air. The injected gas may be produced by introducing part of the fuel oil together with primary air into the burner 3 of a gasifier 2 enclosed in an outer casing 1. Secondary air passes into the casing and thence through ports 5 into the combustion chamber 2, and a mixture of carbon monoxide and other gases from exhaust 6 is fed into the combustion zone of the main furnace. The proportion of fuel oil gasified is not greater than the amount required to burn with the excess air present in the main furnace.
