Patent FI-980281-A (FI)
Inventor: KETTUNEN VEIKKO
IPC: A01G23/081
Filed: 1998-02-06
Abstract: The invention relates to the coupling used to control the function of gripping elements 4,5 in a bulk treating device of a loading harvester. In the arrangement according to the invention, the valve 1 is coupled to the functional unit of the cutting organ of the loading harvester and to the functional unit of the slope of the tilting frame. This coupling operates in conjunction with the tree cutting and felling device in such a way that the gripping element 4,5, which is normally in the fixed position, is made to open at least in the felling position, whenever the rim of the saw or a similar cutting organ performs a movement during the working cycle, or whenever the harvester changes over into the lopping position, and after these functions it shuts off immediately. <IMAGE>

Work-holders.-A work-holder for use in conjunction with a press for carrying out marking operations comprises a plurality of movable platforms and there is provision for moving the platforms selectively into the position beneath the work held by the workholder where marking pressure is applied. In the form of Fig. 1, the work-holder comprises a block 1 in the upper face of which is formed an L-shaped slot, platforms 5a, 5b being slidably received in the two parts 3a, 3b of the slot, each urged by a spring towards the corner position where the marking pressure is applied. When one platform is withdrawn from the corner position by its control rod 8a or 8b, the other platform automatically takes its place. The corners 11a, 11b are chamfered to allow the platforms to pass each other easily. One of the platforms has a plane surface for transferring colour and the other has a part raised for embossing. Locating means for the work may be provided on the upper face of the block 1. In a modification the block 1 has a single straight slot and platforms, one-third the length of the slot, are movable alternatively to the central position where they are retained by a ball-catch. The two platforms may be con. stituted by surfaces of a single movable member displaceable to bring one or the other surface into the marking position. In the form of Fig. 3 the platforms 27, 28 are mounted on a rotary member 26 rotatable between side plates 24, 25 on a spindle 29 controllable by a knob 30.

[Class 142 (iii)] When automatic shuttle changing occurs, the linkage 5, 27, 25, which swings open the shuttle box front 20, also turns a shaft 2 anticlockwise from the position shown in Fig. 2. At first, a spring 6 keeps the nose 18 of a bracket 11 in contact with a segment 14 fixed on the shaft 2, so that a lever 9 enters the path of the picker 12; the bracket 11 is then arrested by an abutment 1 and continued movement of the segment 14 turns the lever 9 about its pivot 8 (by means of a cam face 15), thereby moving the picker away from the shuttle as shown in Fig. 3. The invention is also described as applied to a shuttle box having a vertically rising front.

Abstract: The invention comprises furano chromones of the general formula: <FORM:0948080/C2/1> (in which R is the 5-methyl-isoxazolyl-(3)- or the 3-methyl-isoxazolyl-(5)- radical, R1 and R2 represent alkyl radicals having at most 4 carbon atoms, which may also be bound to each other directly or by way of an oxygen atom, and Z represents a straight or branched alkylene radical having at most 6 carbon atoms), together with a process for their preparation by condensing by means of an alkali metal, alkali metal hydride, amide, or alcoholate, khellinone and a lower alkyl ester of 5-methyl-isoxazole -3- carboxylic acid or 3-methylisoxazole -5- carboxylic acid to form a compound of general formula: <FORM:0948080/C2/2> converting this compound by treatment with an agent which splits off water into a furanochromone, partially hydrolysing the latter, advantageously by means of hydrochloric acid or hydrobromic acid, to form a compound of general formula: <FORM:0948080/C2/3> and reacting the latter in the presence of an acid binding agent, with a reactive ester of a basic alcohol of formula 1-10-ZNR1R2. The novel bases may be converted into their acid addition salts, e.g. picrates. Examples detail the preparation of 4-(b -diethylamino ethoxy) -7- [51-methylisoxazolyl-(31)] -9- methoxy -5H- furano-[3, 2-g][1]-benzopyran -5- one and the analogous 4-(g -pyrrolidyl -(11)- propoxy)-, 4-(g -dimethylamino-propoxy)-, 4-(b -piperidino-ethoxy)- and 4- (S-morpholino-butoxy) compounds, and 4-(b -diethylamino-ethoxy) -7- [31-methylisoxazolyl-(51)] -9- methoxy -5H- furano -[3, 2-g][1] benzopyran -5- one.  5 - [51 - methyl - isoxazole - (31) - carbonylacetyl] -4, 7- dimethoxy -6- hydroxycoumarone (prepared from khellinone and 5-methyl-isoxazole -3- carboxylic acid methyl ester) is refluxed with ethanol/H2SO4 to give 7-[51-methylisoxazolyl -(31) -] -4, 9 - dimethoxy -5H- furano-[3, 2-g][1] - benzopyran -5- one which upon acid hydrolysis yields the corresponding 4-hydroxy compound. 3-Methylisoxazole -5- carboxylic acid ethyl ester similarly yields successively 5-[31-methylisoxazole-(51)-carbonylacetyl] -4, 7-dimethoxy -6- hydroxy coumarone, 7-[31-methylisoxazolyl -(51)]- 4, 9-dimethoxy -5H- furano-[3, 2g][1] benzopyran -5- one and its 4-hydroxy derivative.

[Classes 83 (ii) and 83 (iv).] In welding the seam of a tube &c. a high frequency current is induced in the tube by a transformer and the path of the current is deviated at the point of contact of the edges to be welded. A metal strip is formed into an open seamed tube, by rollers, Fig. 1 (not shown) which is passed through adjustable carriages 6, 14, 27. The carriage 6 carries an insulated seam guide 11, Fig. 3, for maintaining an air gap between the surfaces. On the carriage 14 is mounted a spiral of insulated copper tube 22 which forms the primary of a transformer fed with alternating current of a frequency well above sixty cycles per second by leads 25. Cooling water may be circulated through the tube. The carriage 27 carries roller 36 or dies; Fig. 6 (not shown) for applying welding pressure. The tube to be welded forms the secondary of the transformer and the induced current is deviated by the air gap as shown in Fig. 3. To increase the closeness of coupling of the primary and secondary coils an insulated core secured to a mandrel may be used.
