Title: Improvements in automatic control mechanism of sheet feeders for printing machines and the like
IPC: B41F33/00
Filed: 1925-08-20
Abstract: 250,090. Cleathero, E. T. Aug. 20, 1925. Tripping - arrangements. - The impression mechanism of a printing or like machine is tripped if a sheet is not fed to the front stops of the machine, or if it is fed incorrectly, or if the front edge of the sheet is torn, by mechanism comprising a series of feelers 1 mounted in carriers 2 freely mounted on a shaft 4 mounted parallel to a shaft 6. The feelers are arranged to be oscillated to and from the front edge of the feed-table 23 which is formed with a groove 25. When the sheet registers with the front stops 22, the feelers move on to the top of the sheet, and if the sheet is registered correctly a trip pawl 3 in connection with each feeler carrier 2 is held by the sheet out of the path of a ratchet projection 8 on a bush 7 fixed to the shaft 6. This shaft 6 is acted on by coiled springs tending to move it clockwise, and it is moved in a counterclockwise direction by the action of a bowl 14 on a lever arm 11 fixed to the shaft 6, the bowl 14 being carried by a rod 12 which is reciprocated in a guide 15 by a cam, not shown in the Figure. As the rod moves to the left, the lever arm 11 moves until it encounters a stop B, and this movement of lever 11 acts to depress a link 16 and a weighted lever 18, which controls a pusher rod 19 and allows it to drop out of the path of a trip rod 20 adapted to trip the impression cylinder of the printing-machine. If a portion of the sheet is not present below each feeler 1, a pawl 3 engages the projection 8 and prevents return of the lever 11 to the stop B, so that the rod 19 is caused to trip the impression-cylinder. When the lever 11 is moved counterclockwise bv the rod 12, a screw 10 fitted in a projection 9<a> on the shaft 6 acts on a projection 2a on the carrier 2 and raises the feeler as the sheet advances to registering position. The bushes 7 are connected to the shaft 6 by means of screws 6a which can be loosened if the corresponding feeler is to be held out of action. The ratchet projection 8 is placed against the pawl 3 in this event.

Title: Improvements in starting mechanism for internal combustion engines
IPC: F02N11/08
Filed: 1931-07-22
Abstract: 381,263. Starting prime movers. ECLIPSE MACHINE CO., Elmira, New York, U.S.A. July 22, 1931, No. 20942. Convention date, July 26, 1930. [Class 38 (iv).] In a combined starting and ignition system, for internal, combustion engine, operation of the lockswitch 28 closes a circuit from the battery 10 to the solenoid 26. The main starting switch 19, 20, 21 is thereby closed and current supplied to the starting motor SM. A branch circuit 36 causes the movement of a pivoted arm 47 and brings together contacts 46, 52 closing the ignition circuit from the battery through the coil 54 to the interrupter 44. The action of the windings 36 is opposed by the winding 22 in the main starting-motor lead, thus keeping closed the contacts 31, 32 in the circuit of the solenoid 26. As the load on the starting motor decreases current in the winding 36 increases, and is supplemented by current from the generator G flowing in a winding 40. The contacts 31, 32 separate, breaking the circuit through solenoid 26 with consequent breakage of the main starter circuit at the contacts 19, 20, 21. The action of the coils 36, 40 on the pivoted arm 47 may be supplemented by a second pivoted arm 57 acted on by the solenoid 26. Locking of the switch 28 earths the generator circuit through a lead 42, arm 28b, and connection 43, while the interrupter 44 is also short-circuited at the contacts 46, 51. The casing 17, the sheaths 60, 61 and the casings of the interrupter 44 and lock-switch 28 are made of highly-resistant material for preventing unauthorized use of the apparatus.

Abstract: 765,810. Agricultural implements. CHARRUES MELOTTE SOC. ANON. July 19, 1954 [Jan. 22, 1954], No. 21009/54. Class 6(1). A reversible plough or other agricultural implement having a beam adapted to be raised and lowered, and, when raised, to be rotated by means of a spring which is tensioned when the beam is raised, has the spring connected to members which first act together but are released by its action so that the second half of the rotation of the beam is effected without any hindrance therefrom. The beam 1 is rotatable in the bearing 2 carried by arms 26 which are pivoted to the tractor frame and are connected to the hydraulic lifting links H. Arms 3, 4, integral with the bearing 2, are connected by a link 22 to the tractor, and support a double lever 6 connected by a spring 7 to an arm 9 on the beam. The lever 6 is engaged at its opposite end by a pawl 18 carried by a lever 20 connected to a part of the tractor by a chain 31. Raising of the beam causes the lever 20 to be rocked and, through the pawl 18, to rock the lever 6 and tension the spring 7. The lever 6, through a lost-motion connection 14, 15, 16, raises a catch 11 which is adapted to engage in either of two diametrically-opposite notches 10<SP>1</SP>, 10<SP>2</SP> in a plate 10 secured to the beam. When the coils of the spring close, the spring and arm 9 act as a rigid connection and rock the lever 6 further to disengage the pawl 18 and free the catch 11. The return of the lever 6 can be assisted by an additional spring. In the case of a wheeled plough, the lever 20 is actuated by means of arms secured to the cranked axle of the carrier.

Abstract: 395,523. Knitting-machines. MEIER, R. F., 3830, Reach Street, Philadelphia, U.S.A. July 26, 1932, No. 21111. [Class 74 (ii).] Stockings and other garments are knitted on a full-fashioned machine provided with means for lifting a central portion of the fabric from the needles, means for knitting the outer portion of the fabric, means for lifting an edge of the knitted portion after a number of courses have been knitted and means for transferring the lifted portions to the needles to complete the knitting. The invention is described in connection with the knitting of a stocking, the lifting device, which comprises centre and side topping bars 24 and 22, 20, Fig. 2, respectively carried by a shaft 56, being lowered into position to engage the instep portion prior to the knitting of the heel. The requisite vertical movement is imparted to the topping bars by the engagement of a cam 34 with a roller 38, the latter having a pin connection 40 with a member 42 which, by means of vertical shafts 44, 46, supports a horizontal rotatable shaft 50 associated with the lifting device. On completion of the transfer the pivoted side topping bars 22, 20 are swung through 90‹ by manual operation of bars 52, 54 and during the subsequent knitting of the heel portions the needles of the side bars are pushed downwards one by one, to engage the inside loops, by a cam operated pusher rod 118. The topping bars are moved forward, during the knitting of the side portions, by rotation of the shaft 50 through an internally threaded bevel gear 94, gears 92, 90, 88 and a ratchet driving pawl 80 which is operated by a cam 72 on the cam shaft. A slide 110 controlled by a cam operated arm 106 is connected to a ratchet retaining pawl 98 and is provided with an arm 114 for releasing the driving pawl 80 at the bottom of its stroke. On completion of the heel portions the side topping bars are brought into line with the centre bar and the lifted portions are transferred to the knitting needles for completion of the stocking. The order of lowering the side topping bar needles may be controlled by a chain motion if desired and the innermost selvage loop of the heel may be made larger to facilitate transfer by providing a spring to bear against the appropriate needles. The adjustable mounting of the side topping bars 22, 20 and the provision of extra guide eyes in the centre bar 24 permits variation in the size of the instep.

Title: Improved manufacture of soda, ammonium chloride, nitrate of soda and hydrochloric acid
IPC: C01D9/06
Filed: 1931-07-24
Abstract: In a process for the production of soda, sodium nitrate, ammonium chloride, and hydrochloric acid, solid sodium bicarbonate obtained by the ammonia soda process is converted into sodium cyanide by the action of carbon and nitrogen at high temperature, the cyanide is hydrolysed by treatment with steam to produce sodium hydroxide or carbonate and ammonia, the ammonia being partly returned to the ammonia soda process and partly oxidized to oxides of nitrogen which are reacted with further sodium chloride to produce sodium nitrate and hydrochloric acid. The soda or caustic soda produced in the hydrolysis step may be returned to the cyanidization step one or more times to increase the amount of ammonia produced.  The oxides of nitrogen formed may be oxidized to nitrogen peroxide or converted into nitric acid before reacting with the sodium chloride.  The oxidation of the ammonia to nitrogen oxides may be effected by passing an ammonia-air mixture over a heated iron-bismuth oxide catalyst.
