Title: Improvements in the manufacture of silicic acid sols
IPC: C01B33/141
Filed: 1928-07-21
Abstract: 294,264. I. G. Farbenindustrie Akt.- Ges. July 21, 1927, [Convention date]. Colloidal sols.-Silicic acid sols of high percentage strength (up to 15 per cent. of silica.) are obtained by treating a purified silicic acid get with a small proportion of ammonia and without further dilution subjecting to heat under conditions precluding evaporation. For example, the gel in pieces of 1-6 cms. diameter is immersed for some time in ammonia solution of 0.5-1 per cent strength, or is treated with ammonia gas, and is then heated for 24-18 hours.

Title: A cascade arrangement of an induction motor and a commutator shunt machine with an additional resistance in the rotor circuit
IPC: H02K17/38
Filed: 1927-08-11
Abstract: 276,328. Akt.-Ges. Brown, Boveri et Cie. Aug. 19, 1926, [Convention date]. Alternating - current induction machines. - In an arrangement comprising an induction motor 1 cascaded for regulating purposes with a shuntexcited commutator machine 3 having a resistance in its rotor circuit, the resistance a is inserted between the slip-rings 2 of the induction motor and the branching-off point 6 of the shunt excitation circuit 4 of the commutator machine. In the form shown in Fig. 1, the shunt coils 4 are excited by means of a transformer 5, but this transformer may be replaced by a resistance, or a separate exciting machine may be used. The effects of the resistance is limited to reducing the voltage supplied by the commutator machine without influencing its speed. The speed is controlled by regulating the excitation independently. The resistance, may be regulated by hand or automatically, for instance in dependence upon the speed or current of the machine.

Title: Apparatus for the centreless winding of a length of foil onto a core
IPC: B65H19/22
Filed: 1971-04-19
Abstract: 1291206 Winding webs HERMANN BERSTORFF MASCHINENBAU GmbH 19 April 1971 [19 Feb 1970] 21401/71 Heading B8R Apparatus for winding foil 2 on to a core 6 to form a roll 16 comprises: a preliminary winding station A constituted by a driven contact roller 12 and a pressure roller 8; a final winding station B including the roller 12 and a second contact roller 13 which is displaceable relative to the roller 12; means 21, 22, 23 for transferring a partially wound core from station A to station B; a magazine 3 for empty cores 6; a foil-securing device 10; and a cutter 26. In operation, an empty core 6 is released from the magazine 3 to fall on to the foil 2 when a measuring device (not shown) signals that the roll 16 is almost complete, the core being located on the foil first by a roller 27 and then by the pressure roller 8 which is actuated to press the core on to the roller 12. When the roll 16 has been fully wound the drive to roller 12 is terminated, the device 10 is actuated to positively attach the foil to the core, and the cutter 26 is operated to sever the foil. The rollers 12, 13 are then rotated again to wind a length of wrapping paper 20 around the completed roll 16, and during this operation the foil 2 is also wound on to the new core 6. Meanwhile, roller 13 is moved away from roller 12 so that the completed roll 16 can be discharged downwardly under the action of gravity. The roller 13 is then returned to its original position and the partially wound core is transferred from station A to station B for another winding cycle. During this winding the roller 13 is moved gradually away from the roller 12, and the pressure applied by a pressure roller 17 acting on the roll 16 is reduced as the diameter of the latter increases, thereby ensuring constant winding pressure.

Title: Improvements in or relating to devices for feeding sheets to printing-presses, folding-machines and the like
IPC: B65H3/06
Filed: 1923-08-27
Abstract: 218,151. Spiess, G. Aug. 27, 1923. Tripping-arrangements.-In sheet feeding devices for printing presses, folding machines, &c. in which a feeler pawl 15 on an oscillating lever 13 or 29 engages a driven ratchet wheel and so operates a system of levers to raise the feeding wheel 2 out of feeding position temporarily, and in which the pawl 15 is disengaged from its ratchet wheel by the acceleration of the oscillating lever, the acceleration is increased by a pair of link levers 22, 23 or 29, 30 approaching a straight line position. the acceleration being limited by the straight line position. In operation a sheet fed in by the feed wheel 2 moves the feeler end of the pawl 15 so that the pawl 15 engages with the rotating ratchet wheel 18. The pawl 15 is pivoted at 14 on the lever 13, Figs. 1 and 2, and wheel 18 drives the pawl 15 round until it engages a stop pin 27 on the lever 13. Lever 13 is thus rocked about its pivot 12 causing its race-surface 11 to move under a roller 10 and so raise the end of a lever 8 which is pivoted at 7. Pin 6 of lever 8 thus moves the forked end 5 of the lever 4 which raises the feeding wheel 2 out of feeding position. When the link levers 22, 23 are nearly straightened out the roller 10 mounts the horizontal race-surface 11<a> and resistance is thus suddenly interrupted whereupon lever 13 receives an acceleration from the weight of the link levers which causes the pawl 15 to overrun its ratchet wheel 18 and so free itself with the help of the spring 16. This acceleration ceases as soon as the link levers are in a straight line. The parts are now in the position shown in Fig. 2, the pawl 15 bearing against the pivot pin 12. To reset the device the cam 26 bends the links up again until link 23 abuts against a stop 36 pulling the top of lever 13 to the left so that spring 9 may pull lever 8 back and permit feed wheel 2 to be lowered into contact with the sheets by co-action of cam 20 and rollers 21. Fig. 3 shows a modification in which 29, 30 are the straightening out link levers, the feeler pawl 15 being mounted on lever 29 which is connected by the link 30 to the lever 28. Lever 29 is pivoted at 12 and has its lower end attached to a spring 31 which, while the levers are being straightened out at first retards the movement since its axis of pull lies to the right of the pivot 12, but immediately the axis of pull of the spring has moved to the left of the pivot point 12. the spring gives the levers an acceleration to disengage the pawl 15 from the ratchet wheel 18. A cam 34 on the ratchet wheel shaft acting on a roller 21 brings the levers into feeding position again. The link levers 29, 30 may have a slotted connection to permit play. Fig. 5 shows an addition to Fig. 3 of locking notches 41, 46 and 48 in arms 39, 44 actuated by springs 38, 40 which operate to hold the levers in the stretched position and in the normal starting position.
