Filed: 1953-04-30
Abstract: 748,773. Printing-machines; feeding sheets. TIMSONS, Ltd., and TIMSON, E. A. April 22, 1954 [April 30, 1953], No. 11971/53. Classes 100 (1) and 100 (2). Tripping-arrangements; faulty sheet-feed control devices.-In a rotary offset machine including offset, impression, and printing cylinders 1, 2 and 3, respectively, wherein the offset cylinder 1 is adapted to be lifted away from the other cylinders when a sheet is not fed to the cylinder 2, sheets are advanced over a feed board 4 up to oscillating stops, and are then transferred to grippers 7 on the cylinder 2 by a series of grippers 6. The grippers 6 may be mounted on oscillating levers or, as shown, on spaced discs 8 secured to a shaft 9 rotated stepby-step by a Geneva mechanism. Each gripper 6 comprises a movable jaw 10 which co-operates with a fixed jaw 12 on the disc, the faces of the jaws constituting pairs of electric contacts included in the circuit of a solenoid 13. Thus the faces are separated when they grip a sheet on the board 4, but if a sheet is absent they make contact and complete the circuit to cause the solenoid 13 to be energized. When this occurs, an armature 13a, and a link 24 connected thereto, is drawn downwardly to rock a bell-crank 23 which pulls links 21 to the left and breaks toggles 20 interposed between the links 21 and vertically slidable bearings 15 of the offset cylinder 1. The bearings 15 are now urged upwardly by one end of an arm 11 pivoted at 17, the other end of the arm being urged downwardly by a tension spring 18 secured to a screw 19. The bearings, toggles and levers are restored to the original position automatically by a cam 28, secured to the cylinder 1, engaging a roller 27 on the bell-crank 23.

Title: Conveyor leveling mechanism for harvesting machine
Inventor: MCROBERT LEON RODGER
IPC: A01D75/28
Filed: 1969-03-07
Abstract: 1,221,408. Conveyer levelling mechanism. FMC CORP. 7 March, 1969 [10 April, 1968], No. 12072/69. Heading A1F. [Also in Division B8]  A crop harvesting machine comprises a frame with at least one conveyer for moving the crop pivoted thereon and poweroperated means being provided to maintain the conveyer in a horizontal plane to compensate for any tilting of the frame as the machine moves over uneven ground. In a potato harvester the crop is extracted from the ground by blades 16 and transferred to the conveyer 18 from where it is dropped on to an endless transverse rod belt 24. The crop is then transferred to a similar type of conveyer 26 and from there to the conveyer 31 at 31a. The conveyer 31 has a humped portion 31b which carries the crop under the hood 60. A blower 87 is arranged to suck air through the open part of the hood 60 adjacent to the conveyer 31b. The potatoes are lifted off the conveyer 31 whereas stones due to their larger weight remain on the conveyer and are ejected. The potatoes or other crop are then deposited on conveyer 70 and moved along to be collected. In order to maintain the efficiency of the sorting process the potatoes must be kept evenly distributed on the conveyers and to this end the conveyer 31 is pivoted to the frame of the harvester at 112 and a hydraulic ram 122 is connected to the conveyer so that under manual operation of a spool valve the lateral attitude of the conveyer is altered to keep the distribution of the crop uniform. The spool valve may be operated by a solenoid which is activated by a control valve operated by a pendulum so that any variation in the lateral tilt of the harvester operates the solenoid such that the conveyer is kept horizontal with respect to the ground. The conveyer 26 may also be arranged to be kept horizontal by means of the master and slave hydraulic rams 152 and 158 whereby any motion of the conveyer 31 moves the piston in the master cylinder 158 and thus, through the hydraulic conduits 164 and 166, the slave ram 158 imparts a similar motion to the conveyer 26. A similar hydraulic mechanism may be employed to tilt one of the conveyers longitudinally in addition to laterally to further compensate for tilting of the harvester over uneven ground.

Title: Improvements in or relating to feed mechanism for automatic guns or machine guns
IPC: F41A9/77
Filed: 1939-08-04
Abstract: 572,510. Automatic guns. MOTLEY, L. Aug. 4, 1939, Nos. 12277/40 (divided out of 572,504), 31058/39 and 4448/40. [Class 92 (ii)] Cartridge feed mechanism for automatic guns comprises a worm conveyer 10, Fig. 2, for engaging the rounds 1 which is driven by a motor 13, normally operative only when the gun is firing, through the medium of a resilient power storage transmission, such as a spring 14, Fig. 5, the said transmission being preloaded, thereby biassing the ammunition towards the gun prior to firing and ensuring the feed as soon as firing commences. The invention is shown applied to a magazine as described in Specification 572,504, in which the rounds are carried in a number of vertical compartments 2 having automatically controlled shutters 4, a worm conveyer 10 being provided to feed the rounds through a channel 3 to a passage 11 leading to the gun. The sprocket 21 of the worm conveyer is driven by an air motor 13 through a spring 14, sprocket 19, and chain 20. Air pressure is first admitted to the motor by pressure on the gun trigger with the gun at "safe." The spring 14 is thus preloaded to rotate the worm and bias the cartridges towards the gun. Reaction of the spring on the motor is prevented by ratchet gear 16. With the gun ready to fire, the motor begins to rotate the worm conveyer when the gun trigger is pressed. To maintain pressure on the last few. rounds in the passage 11, a telescopic spring-pressed pusher 22, pivoted at 25, is provided. The pusher normally occupies the position shown with its roller 26 in engagement with an incline 27. When the last column of the magazine is exhausted, the pusher rises and the roller enters the passage 11. The rounds are pressed downwardly in each compartment by the spring arm mechanism 5 described in Specification 572,505.

Title: Process of recovering vanillic acid from lignin
IPC: C08H5/00
Filed: 1945-05-24
Abstract: Vanillic acid is recovered from lignin by digesting (e.g. under reflux, or at 125-175 DEG  C. under pressure) an aqueous alkaline lignin containing mixture in the presence of mercuric oxide; acidifying the reaction mixture with sulphurous acid, removing the precipitate containing all the mercury, acidifying the liquid remainder with a strong acid, e.g. sulphuric acid, extracting the acid liquor with a water-immiscible solvent and then recovering the vanillic acid by the extraction of the non-aqueous extract with sodium bicarbonate.  The precipitate containing the mercury may be processed to recover the mercury for the formation of mercuric oxide for use in the continuation of the process.  The process is applicable to any lignin-containing material derived from any source, e.g. to cellulose-free lignin compositions found in waste pulping liquors and especially to calcium lignosulphonate.  Hard wood lignin produces syringyl compounds in addition to the quiacyl compounds obtained from soft wood lignin. In examples: (1) calcium lignosulphonate is refluxed with a suspension of preformed mercuric oxide in aqueous sodium hydroxide and processed as above, producing vanillic acid; (2) as in (1) but adding calcium lignosulphonate to a hot suspension of mercuric oxide in aqueous sodium hydroxide, obtained by hydrolysing mercuric chloride with an excess of sodium hydroxide solution; (3) as in (1) but adding calcium lignosulphonate to an initially cold suspension of fresh mercuric oxide in aqueous sodium hydroxide, obtained by adding mercuric acetate to excess of sodium hydroxide solution.
