Abstract: 177,410. Moore, G. W., and Deacon, W. April 2, 1921. Potato diggers.-A machine for digging potatoes comprises a fork-wheel rotating in the same direction as the road wheels and having its axis parallel to the road-wheel axle and a hood or casing enclosing the fork-wheel and having an outlet at the bottom. The fork-wheel is mounted in arms 8 pivoted on the frame and supported by springs 9. The arms are fixed in position by a catch engaging a toothed quadrant 23 and actuated by a camlever 20 and spring 27. The fork-wheel is as wide as the base of the potato ridge, and consists of a drum 13 provided with teeth 12, or fork sections, arranged in rows parallel to the axis of the drum. The teeth 12 may be circular in section at the top and elliptical at the base. The drum 13 is driven by chain gearing and a clutch. The arms 8 carry the casing 11 and the support 17 for the digging-share 16. The casing 11 consists of a skeleton metal frame covered with canvas &c. The top and sides may be hinged. The potatoes fall through the outlet C behind the share 16. The axle 24 and fork-wheel spindle 14 are mounted in ball, roller, or sleeve bearings. The horse shafts are fastened to brackets 15, which are adjustable laterally for use with one or two horses. The brackets may be secured by T-bolts sliding in transverse slots.

Abstract: 196,284. Lebeau, P. April 12, 1922, [Convention date]. Void [Published under Sect. 91 of the Act]. Locking-bolts and devices.-Points are locked by a pivoted locking-piece g which moves downward into locking position. The piece g has a head e pivoted at o to a bracket d fixed to the tongue f and carries a bar h which engages upright members m of a frame c bolted at 3 to the rail 2, the engaging faces of the parts h, m being curved about the centre of the bolt o when the tongue is home. The piece g has a slot k engaged by a pin l which is carried by the plunger b which is in two parts to embrace the piece g. The plunger b is guided by rollers p on the frame c and is connected by a rod a to a ground levelr, &c. The two tongues may each be provided with a locking-device which are interconnected. To lock the points only in the closed position, Fig. 6, the members m have a flat surface t engaged by rollers s carried on the piece g. In this form, the points can be opened by a vehicle trailing through. To lock the points in both open and closed positions, Fig. 8, the rollers s engage cam grooves n in the member m which is curved at u to engage the opposite face v of the bar h, flanges r limiting the upward movement of the piece g. The piece g may have an arm a<2> provided with a pin b<2> which engages a slot c<2> in a lever d<2> secured to the shaft 5 of a cylinder having electric contacts to close the circuits in different positions. Thus, with the lever d<2> moving through the angles z, y x during the unlocking, travel, and locking of the points, a circuit may be closed through the lower part of the angle x to indicate that the points have been operated and locked.

Title: Removal of a metal pentafluoride from hydrocarbons
IPC: C07C9/14
Filed: 1974-03-06
Abstract: 1458692 Removing metal pentafluoride catalysts from hydrocarbons EXXON RESEARCH & ENG CO 6 March 1974 [2 July 1973] 9971/74 Heading C5E TaF 5  and/or NbF 5  are removed from hydrocarbon streams by extracting with liquid HF (containing not more than 2% water) at 0-200 F., 20-250 psig and recovering the hydrocarbon stream having a reduced content of metal pentafluoride. The extraction is preferably a countercurrent liquid-liquid extraction. HF may be removed from the extract by distillation. The metal pentafluorides are used as catalysts with HF for hydrocarbon conversions, e.g. isomerization and the impure hydrocarbon streams are obtained after removal of most of the catalyst in an acid phase. In an example TaF 5  is extracted from n hexane.

Title: Editing controller
Inventor: NEDACHI SATORU
IPC: G11B27/28
Filed: 1992-01-08
Abstract: PURPOSE:To enable editing in the case of video editing while improving editing accuracy and always getting color framing. CONSTITUTION:The video editing is executed by detecting the color phase of a reference signal by a phase detecting means 4, instructing the write of the color phase in the user's bit of a time code generator (TCG) 7 at a recording VTR 2 by a communication control means 5b, writing the color phase in the case of recording onto a time code, and instructing the read of the color phase recorded in the user's bit of the time code from a communication control means 5a to time code readers (TCR) 6a and 6b. Thus, since the color phase of a video signal recorded in a tape can be surely read out and the color phase at that time can be written in the case of recording, the color framing editing with high editing accuracy can be executed without using any function of the VTR itself for a color framing operation normally required in excess.

The ratio of the level fluctuations of both components is obtained with a level-fluctuation ratio computer 31. A weight-coefficient judging device 32 outputs the weight coefficient having the discrete value in response to the level fluctuation ratio having the continuous value. The weight coefficient outputs are accumulated by the specified number in the time direction with an accumulator 33. Thereafter, the accumulated result from the accumulator 33 is compared with a specified threshold value TH in a comparator 34. The cavitation noise is detected based on the result of the comparison.
