Title: Improvements in or relating to tractor-implement combinations
Inventor: EXLEY GEORGE ERIC
IPC: A01B63/114
Filed: 1959-12-04
Abstract: 870,977. Fluid-pressure servomotor control systems. EXLEY, G. E. Dec. 4, 1959 [Feb. 6, 1959], No. 41222/59. Class 135. [Also in Group XXXI] In an agricultural tractor implement combination in which the implement, such as a plough, is mounted on the tractor by means of a three-point linkage operable by an hydraulic power unit on the tractor, provision is made whereby the hydraulic power unit is caused to maintain automatically a preselected working depth of the implement despite irregularities in the ground. An arm 1, Fig. 1, pivoted at 2 to the tractor frame, is provided with a wheel or other ground-engaging member 4 and is connected by a link 5 to one end of a bell-crank lever 6, pivoted to an arm 7. The other end of the lever 6 is connected by a link 10 to a plunger 11, Fig. 4, which is recessed to receive a hardened steel ball valve 16. The valve 16 with its seat 17 is mounted on the tractor and controls the by-pass, to a tank 9, of the delivery from an oil pump driven from the tractor which supplies oil to an hydraulic ram controlling the lift arms of the linkage. The initial setting of the working depth is made by rotation of a rod 24, which adjusts the relative position of the usual ram-actuated lift arms 22 and the lever 7 and hence the relative positions of the lift arms 22 and the ground-engaging member 4 for the normal position of the valve 16. In operation, if the wheel 4 encounters a rise in the ground, the arm 1 and lever 5 are displaced upwards and the valve 16 is moved towards its seat increasing the pressure fed to the ram whereby the implement is raised through the arms 22 until the preselected working depth has been restored when the valve returns to its normal setting due to the movement of the lift arm 22 acting through rod 24 and lever 7. If the wheel 4 encounters a fall in the ground level, the valve 16 is opened to decrease the pressure in the ram causing the implement to be lowered to its predetermined depth. The valve 16 may be a rotary, piston or poppet valve and the arm 1 may be formed with a yieldable device to safeguard the mechanism. The above arrangement of a restricted circulation of oil creates a pressure in the ram cylinder to exert an upward thrust on the implement without raising it thereby transferring a proportion of the weight of the implement to the driving wheels to increase the tractive effort.

Title: Wire bending machine
Inventor: REISING PAUL JOSEPH
IPC: B21F3/12
Filed: 1969-08-19
Abstract: 1285757 Making springs; coiling helices LEAR SIEGLER Inc 19 Aug 1969 41247/69 Headings B3A and B3E A method of making a continuous spring strip comprising alternate right and left handed helical coils from a continuous integral length of wire comprises coiling the wire in a clockwise path relative to a guide to form a helix in one direction and coiling the wire in a counterclockwise path relative to the guide to form a helix in the opposite direction. A roller feed 18 moves the wire 20 through the guide 22 into engagement with a forming roller 24 to form a clockwise helix. A second forming roller 26 also mounted on a slide 46 can be moved by an hydraulic cylinder 42 into the path of the wire to form an anticlockwise helix. After the formation of a helix the forming rollers are moved out of engagement with the wire so that straight portions of wire are left between each set of helices. Adjustment between the guide and the forming rollers deter. mine the radius of curvature of the helices- Instead of the frusto-conical rollers right cylindrical rollers can be used to coil the wire and an additional member (not shown) included to contact the wire immediately as or after it is coiled to impart the desired pitch. In a modification the guide tube is reciprocated and the rollers kept stationary and in another modification a single roller is swivelled from one side of the stationary guide tube to the other to form helices of opposite hand.

In a wrapping machine, an article A, Fig. 2, to be wrapped, is placed in a pocket 6 in and intermittently rotating drum 1 at a feed station. As the drum rotates, moving the article from the feed station to an ejection station, wrapping material W, held by suction on the surface of the conveyer, is drawn over the exposed surface of the article, so that when it is ejected from the conveyer the wrapping material extends over its exposed and adjacent sides. The web W of regenerated cellulose or other plastics material is fed through draw rollers 2, guide rollers 3 and a clamping device 4 to the drum 1. If required, a tear strip T may be applied to the web W before it arrives at the rollers 2. In one embodiment, Figs. 1-5 (not shown), the partially wrapped article is ejected from the drum by a device inside the drum against the tension of the wrapping material, a length of which is cut from the web by a knife 9 after the article has been ejected. The wrapping material is then folded over the top surface of the article by a suitable folding device (not shown), the partially wrapped package being then pushed into a folder box in which the wrapping is completed. In a second embodiment, as the article A arrives at the ejection station, clamps (11), (12), Fig. 6 (not shown), the former being mounted in the drum, close on the article, which is ejected while held by both clamps after a length of the wrapping material has been cut from the web. The leading and trailing ends of the wrapping material are then folded round the article and the overlapping portions heat sealed together. The package finally passes means for folding and heat sealing the wrapping material over the ends of the package. The apparatus can be used to provide a wrapper which is open at both ends.

Filed: 1962-11-13
Abstract: Actinamine, or 1,3-deoxy-1,3-bis (methylamino)-myoinositol is prepared by treating actinospectacin with a mineral acid, particularly hydrochloric acid.  On acylation actinamine is converted to hexaacylatinamine which on methanolysis yields N,N1-diacylactinamine, and mixed acylates can be obtained by acylating N,N1-diacylactinamine with a different acylating agent. Actinamine may also be alkylated to N,N1-dialkylactinamine which may be acylated to give N,N1-dialkyl-O2, O4, O5, O6-tetraacylactinamine. Acyl groups which may be incorporated by the above acylation reactions include hydrocarbon carboxylic acid acyl of from two to twelve carbon atoms, inclusive, halo-, nitro-, hydroxy-, amino-, cyano-, thiocyano- and lower alkoxy-substituted hydrocarbon carboxylic acid acyl of from 2 to 12 carbon atoms, inclusive, and lower alkoxy-carbonyl, the term "lower-alkoxy" denoting an alkoxy group of from 1 to 6 carbon atoms.  Actinamine acylates have antibacterial activity. Specification 959,675 is referred to.
