Title: Mupltiple bearing
IPC: F16C27/08
Filed: 1947-04-23
Abstract: 623,275. Bearings. KENDRICK, J. F. April 23, 1947, No. 10878. [Class 12 (i)] In a multiple bearing comprising an assembly of a plurality of individual bearing units, means for equalizing the load on each comprises interposing plastically deformable washers 21 (e.g. of lead, copper, zinc, aluminium and their alloys, bronze, or beryllium copper), between the bearing units and their supports. A plurality of thrust bearings 10, Fig. 1, have load equalizing washers 21 between each lower race 10a and each bracket shelf 11a of the stationary member of the bearing assembly. The washers 21 are designed so that the yield pressures will occur above the normal rated capacity of the bearing. Thus the bearing is initially subjected to a progressively increasing loading pressure until such plastic deformation of the washers is effected as to distribute the total load on the assembly over the bearing units. Similar washers may be interposed between the upper races 10b and housings 13. In a bearing having an extremely narrow race, a sole plate 23 may be interposed between the race and the washer 21, Fig. 3. A construction, Fig. 4, wherein the deformation of the loadequalizing washers may be arrested comprises the bearing races 10a, 10b set in recesses 24 provided in the housing flanges 25, 26, the recesses 24 being undercut at their bottoms, thereby providing spaces 28 into which the material of the load-equalizing washers may be forced. The deformable washers may have age-hardening characteristics. A concentric multiple thrust bearing with deformable washers 21 and a multiple radial bearing having deformable encircling rings are also shown, but the invention may be applied to any type of bearing.

Patent GB-459599-A (GB)
Title: An improved process for purifying crude hydrocarbons
IPC: C10G29/20
Filed: 1935-04-09
Abstract: Low boiling crude hydrocarbons, e.g. crude benzole, are purified by passing the vapours thereof through a purifying agent consisting of carbolic acid or homologues thereof, e.g. cresol and/or oil fractions which contain tar acids from mineral tars, brown coal tars, or low temperature distillation tars, either alone or in admixture with hydrocarbon oils, the temperature of the purifying agent being maintained above the boiling point of the hydrocarbon to be purified. In the case of a crude benzole boiling over a range of 80 to 150 DEG C., the temperature is initially maintained at about 100 to 120 DEG C. and is then increased gradually to about 170 to 180 DEG  C.  The hydrocarbons may be preliminarily washed with acid and alkali.  In carrying out the invention, the hydrocarbon vapours from a stripper are led through a plunge pipe with a sieve bottom into a vapour-heated washer containing the purifying agent and provided with a stirrer or packed with Raschig rings, the purified vapours passing to a condenser.  After passing through the washer, the vapours of the higher boiling fractions may be passed through a filter charged with alkaline earth, e.g. bleaching earth, with or without an addition of barium hydroxide, before passing to the condenser.  In examples, the vapours of crude benzole are passed through either (1) cresol, the vapours passing off above 120 DEG  C. being then passed through a filtering layer of bleaching earth and barium hydroxide; (2) carbolic oil containing 40 per cent of phenols or tar acids; and (3) a mixture of cresol and Solvay oil.

Title: Dispensing apparatus
IPC: A01C9/08
Filed: 1971-04-23
Abstract: 1392035 Planting machines NATIONAL RESEARCH DEVELOPMENT CORP 18 April 1972 [23 April 1971] 11028/71 Heading AID [Also in Division B8] A machine for planting seed potatoes, bulbs or the like includes a storage hopper, a pair of feed rollers whose outer surfaces are coated with a soft resilient layer e.g. neoprene, and an inclined chute extending between the hopper's bottom outlet and the feed rollers and which is oscillated about and/or reciprocated along its longitudinal axis so as to form therein a row of contiguous seed potatoes or the like. Alternatively the chute may be rotated continuously. In a first embodiment of a potato planting machine (Figs. 2, 3), a pair of agitating rollers 123, 124 are positioned adjacent the outlet 122 of a hopper 118 and are contra rotated by sprocket wheels 107, 108 driven off a ground wheel via a chain and sprocket transmission, so that the opposing surfaces move upward. Each of the rollers has a non circular cross-section e.g. elliptical and the rollers are arranged to rotate out of phase e.g. by 90‹ so that the gap therebetween reciprocates laterally and aids the passage of potatoes into the chute 109. The floor of the storage hopper 118 comprises two hinged flaps 138 supported at their free edges on cams 139 fixed to the shafts of the rollers 123, 124 and which are agitated thereby. The flaps 138 are covered in soft material e.g. rubber. The chute 109 comprises an open channel 119 which is reciprocated by a rotating sprocket wheel 127, driven from the ground wheels, which strikes against a projection piece 128 on the channel 119 and causes periodic movement of the chute against a return spring 129. The movement of the potatoes in the chute is further facilitated by an endless belt 142 mounted to travel along the length of the chute from the outlet 122 to a subsidiary channel 130 and to engage the upper surface of the potatoes. The belt is driven by a chain 165 from the roller 120 and is geared so that it moves at a rate slightly greater than the speed of the potatoes. The seed potatoes are deposited by the rollers 120, 121 into a furrow formed by a share 141 and the rate of feeding the potatoes is controlled by the speed of the rollers 120, 121 which are driven by a ground wheel via a chain and sprocket transmission. In a second, similar, embodiment (Figs. 5, 6, 7 not shown) the chute 109 comprises a tube whose internal bore may be varied to accommodate various potato grade sizes by inserting a liner therein. The various rotary elements are driven from a gear box which, in turn, may be driven from a land wheel or from a tractor power take off. In alternative embodiments, the potatoes may be fed from the hopper to the chute by a conveyor belt positioned to lift potatoes from the lower end of the hopper and to pass there to an opening at the upper end of the hopper. In a further arrangement, the feed tube may be arranged to oscillate with an amplitude of 20‹ or may rotate continuously.
