Title: Photographic apparatus
IPC: G03B17/50
Filed: 1964-01-10
Abstract: In an arrangement in which a photo-conductive sheet is subjected to successive exposures each followed by an electrolytic development in a dye bath, a rinsing step to recover its dark adaptation and a drying step to restore its uniform photosensitivity, the sheet is carried both during exposure and its subsequent treatment on a fixed or movable platen. In one form Fig.7, (not shown), the platen is movable to submerge the sheet in developer baths which are each successively moved into the development position. As shown, a sheet 28 having a photo-conductive insulating coating on a conductive backing is retained by suction on a platen 14. The top of the sheet is secured by members 98 forming the cathode connection. After exposure to the projected colour separation image of a multi-colour negative, the appropriate developer bath, having a plate, strip or reticulated anode 74, is raised in cradle 32 by hydraulic cylinder 66. After development, bath 16 is lowered on to turn table 18 which is then free to align the next bath 16 with lifting cradle 32. As water collecting funnel is moved from 68B to 68A, a stream of water is spread over the coated face of the sheet by retractable water knife 20 and the platen is washed by spray 78. The washing water may be warmed to effect the dark adaptation of the sheet or, alternatively, it may be subsequently heated by infrared radiation or warm air. Air knives 22 are movable vertically by means of hydraulic cylinder 62 to dry both the sheet and platen. It is stated that either A. C. or D. C. may be used for development and that the developer may be poured on to the sheet through an orifice containing an anode wire.

IPC: C12H1/00
Filed: 1967-04-18
Abstract: In a process of fermenting and aging a malt beverage, fermentable yeast-containing wort is continuously agitated, as by circulation through a heat exchanger, at a first temperature between 45 and 70 F. until the specific gravity of the fermented wort decreases to a predetermined value 5 degrees plato to produce a beer and the beer is aged, for a period of from one to five days, by continuously agitating or circulating it at a temperature at least 4 F. above the first temperature, preferably in the range 50 to 75 F., until the product has satisfactory organoleptic qualities viz. predetermined values of acetaldehyde content and diacetyl content below 5 ppm and 0À2 ppm res- pectively. Alternatively, when the diacetyl content has decreased to a value below 0À5 ppm, the temperature may be taken to between 32 and 55 F. until the acetaldehyde content reaches the predetermined value below 5 ppm. The aged beer is cooled to between 29 and 32 F. for the yeast and haze components to be separated by centrifuging. A substantial proportion of the yeast may be removed before the aging.

Patent ES-360102-A1 (ES)
Title: High-speed tree harvesting apparatus
IPC: A01G23/08
Filed: 1968-10-25
Abstract: A tree harvesting apparatus comprises means 500, Fig. 1, on a vehicle 610 for delimbing trees in an upright position, and means 200 carried by the vehicle for delivering cut trees to the delimbing means. The vehicle also carries a collector 800 for accumulating delimbed trees. The vehicle has a pair of tracks 108 and a swingable platform 110 which is rotatably adjustable by an hydraulic drive. An hydraulically operated articulated boom 200 is mounted on the front of the platform and at its forward end carries a grapple 300 comprising pairs of hydraulically operated jaws for gripping a standing tree. Below the grapple is a shear mechanism 400 consisting of a pair of blades 426, Fig. 8, movable about a pivot 428 by hydraulic cylinders 410, 412 to effect shearing of the standing tree. After shearing, the boom is retracted with the grapple 300 holding the tree to position the tree adjacent a transfer grapple 500. The jaws 314, 316 of the grapple 300 are carried by an auxiliary frame 338 which is rockable by a cylinder 342 about a pivot 340 on the frame 302 of the grapple carried by the boom member 204 to position the tree in the jaws 522, 524, Fig. 10, of the transfer grapple, the jaws being actuated by cylinders 532 to grip the cut tree. The boom can then be actuated to grip and cut a further tree while the cut tree is automatically delimbed, topped and transferred to the collector. With the cut tree gripped by the jaws of the transfer grapple, a pair of shear blades 612, 614 of the shear mechanism 610 are resiliently urged by cylinders 624, 626 to encompass the cut tree, and the mechanism is urged upwardly along a track 608 on an upstanding mast 602 by an hydraulic cylinder 642 acting through a motion multiplying pulley arrangement 636, 640 and cable 632 so that the blades delimb the tree by impact shearing. When the blades reach a predetermined diameter of the cut tree, a cam operates through an hydraulic cylinder 750 (Fig. 15), to pivot a pair of blades 702, 704 towards a horizontal position to cut off the top of the tree, the blades being mounted on the upper part of the shear mechanism. After delimbing, the shear blades 612, 614 are retracted and an auxiliary frame 512, Fig. 10, carrying the jaws 522, 524 of the transfer grapple is swung about a pivot 510 by a cylinder 514 to transfer the cut and delimbed tree to the collector 800, Fig. 1. The latter consists of a U-shaped frame having at its open end a pair of gates which are urged to a closed position and through which the tree is forced by hydraulically actuated arms 846. The tree is held upright in the collector by hydraulically urged transverse bars which move rearwardly to accept further cut and delimbed trees into the collector. When the collector is full, the trees may be wired together and the platform 110, Fig. 1, turned through 180 degrees. The collector can then be tilted by an hydraulic cylinder about a horizontal pivot to dump the trees on the ground when the gates of the collector are opened.

Title: Electrode cleaning mechanism for electrostatic dust precipitator
IPC: B03C3/76
Filed: 1973-02-16
Abstract: An electrode cleaning mechanism for electrostatic dust precipitators is disclosed which has at least one eccentrically mounted electrode vibrated by a rapping mechanism which includes a tumbling hammer that is rotated about a horizontal shaft so that it continually swings down in a pivotal pendular movement until the impact surface of the hammer strikes against the end of a rapping bar which is thus sharply moved axially out of a rest position to jar the electrode. The rapping bar is urged back to its rest position after jarring the electrode by the weight of the eccentrically mounted electrode which is connected to the rapping bar during this return movement.
