Abstract: 1,070,346. Peeling tomatoes. G. BUSCETTO. Sept. 7, 1965 [Sept. 22, 1964; June 24, 1965], No. 38216/65. Heading A4C. A tomato peeling machine includes a plurality of peeling devices 4 each comprising a hollow, open ended body 27 carried by a moving support 28, a perforated wall 29 mounted within the body 27 with an annular space 30 therebetween, an elastic jacket 32 with a roughened inner surface secured by enlarged end flanges 33 within the perforated wall 29, means 41, 37 for supplying air under pressure to within and outside the jacket 32, and a cutting device over which the support 28 is moved to cut the skin of a tomato 8 supported in a deformed jacket 32<SP>1</SP>. In operation, tomatoes are fed singly from a hopper 26 into the jacket 32 and compressed air from a toroidal channel 41 urges the tomato 8 to the middle of the jacket. Compressed air is then passed through an inlet 37 to act on the outer surface of the jacket 32 and deform it, as at 32<SP>1</SP>, to a tomato skin gripping position. The lower, stem end of the tomato has its skin cut so that the skinned tomato is ejected from the jacket 32 and the skin remains adhered to the jacket 32. The hollow body may be of cylindrical form (Figs. 9, 10) and is selectively fitted with one of a number of alternative perforated walls (44) and jackets (46) according to the size of the tomatoes being skinned. The moving support 28 may be in the form of a rotary disc (3) or an endless conveyer (12) each carrying a plurality of rows of peeling devices 4, the tomatoes being fed to the support by a conveyer system which is advanced synchronously with the operation of the peeling devices. An electronic device senses the difference in ripeness between the zone of the stem of the tomato and the tomato itself and energizes an elecromagnet which rotates the peeling device through 180 degrees if the tomato is wrongly oriented therein.

Title: Method and apparatus for drilling underground arcuate paths
IPC: E21B7/04
Filed: 1975-09-17
Abstract: 1521974 Boring earth etc. TIDRIL CORP 17 Sept 1975 [17 Sept 1974] 38244/75 Heading E1F When drilling along an underground arcuate path 18 beneath an obstacle, e.g. water 10, from a first position 12 at or near ground level on one side of the obstacle, to a second position 14 at or near ground level on the other side, a pilot hole is drilled along the path 18 using the drill string 22 and a liner 24 is thrust into the ground, the liner 24 surrounding the drill string 22 and the leading end of the liner 24 being spaced from the leading end of the drill string 22.  As described the drill string 22, which is not rotated, carries a directional drill 20 which is powered by drilling mud supplied through the drill string 22. The liner 24 has a cutting edge (not shown) at its leading end and is rotated as it is thrust into the ground about the drill string 22. The string 22 and liner 24 are forced into the ground by drillrig 26 including a drill head 52 which rides along ramp 50. The drill head 52 includes an outer chuck 56 which can be connected to the liner 24 and is rotated by drive sprocket 88, chain 86 and sprocket 82 and a removable inner chuck 80 which can be connected to the drill string 22. Drilling mud is supplied to the drill head 52 through hose 64, T-fitting 60, bell housing 90 and cylinder 88, the end cap 94 of the T-fitting 60 being removable. In use a section of drill string inside a section of liner are placed between the drill head 52 and the bore hole and the sections are joined to the string 22 and liner 24 in the hole. With the chuck 80 and cap 94 removed (so that the drill string section can pass through the drill head 52) the liner section is joined to the chuck 56 which is rotated and the drill head 52 is forced down the ramp 50 to thrust the liner 24 into the ground. The liner is then disconnected from chuck 56 and the drill head 52 is returned to its initial position where chuck 80 and cap 94 are replaced. The drill string section is then joined to chuck 80 and drill head 52 is again moved down the ramp 50 to force the drill string along path 18. The chuck is not rotated except to control the azimuth of directional drill 20. The procedure is repeated until the hole is completed. Drilling mud returns along the annulus between liner 24 and string 22 and collects in a pool 68 where the cuttings settle out, mud being returned to the pump through line 70. In a modification (not shown) the drill string 22 and liner 24 are advanced simultaneously.

Title: Paper perforator
IPC: B26F1/36
Filed: 1977-09-14
Abstract: The letter perforator has a lower part composed of a base plate (1) which forms the punching die and two edge side parts (11, 11') which are connected to the said plate and on which there are formed tabs (12, 12') which contain the punch guides (13, 13'). The entire lower part is punched from a piece of sheet metal. The web forming the punching die is formed by a part (2) which is cut away from the base plate (1) on three sides of a rectangle, is initially bent approximately vertically upwards and is then bent horizontally backwards. By means of lateral tabs (9, 9') which rest on edges (10, 10') of the side parts (11, 11') which are bent upwards at right angles, the punch pressure is transferred to the lateral parts (11, 11') which contain the bearings (16, 16') of the pressure plate. Deformation of the perforator is avoided in this manner, despite the thinness of the sheet metal from which the base plate (1) is formed. <IMAGE>

Title: Process for the manufacture of mercaptans
IPC: C07D233/93
Filed: 1964-09-22
Abstract: Alkyl mercaptans are manufactured by a process in which hydrogen sulphide is caused to react with at least one saturated aliphatic hydrocarbon by igniting and feeding a flame with a mixture of hydrogen sulphide and the hydrocarbon and immediately cooling the reaction products formed.  The flame is preferably an inverse flame, that is to say, the combustible gas to be burnt is fed in the form of a stream which surrounds the stream of combustion supporter.  The combustion supporter is preferably oxygen, which may be diluted with an inert gas such as nitrogen, alternatively air may be used. Preferably the proportion of hydrogen sulphide relative to that of the hydrocarbon is equal to the stoichiometric ratio.  A suitable apparatus for carrying out the process comprises a burner with three concentric conduit means through which the separate gases are passed or alternatively a mixture of hydrogen sulphide and hydrocarbon which has been mixed beforehand may be used.  The gases leaving the burner are ignited and then cooled, preferably by a heat-exchanger containing liquid nitrogen positioned at the apex of the flame. Exemplified hydrocarbons are methane, ethane and propane.

Title: Method of manufacturing a tubular conductor comprising a layer of niobium superconductor and a layer of metal which is not superconductive at a temperature at which the niobium is superconductive
IPC: H01L39/06
Filed: 1972-08-18
Abstract: 1397785 Making super-conductive cables; welding by fusion SIEMENS AG 18 Aug 1972 [19 Aug 1971 (2) 2 Nov 1971] 38749/72 Headings H1A and A4D A method of making a tubular conductor comprising a niobium layer and a layer of another metal includes making a strip of the two layers with fillets of niobium along its edges, bending the strip into a tube so that the niobium fillets abut one another and securing the fillets together. Niobium strips (4), 5 Fig. 1 (not shown), are drawn between rollers 24, 25 by a support 10 and a strip 2 of niobium foil is simultaneously drawn on to the strips. The edges of the foil strip are electron beam welded to the strips (4), 5 to form a channel section strip. The welding apparatus and support are located in a housing 12 provided with a branch 14 leading to a vacuum pump. The channel section niobium strip is fed to a vacuum housing (12<SP>1</SP>), Fig. 4 (not shown), where a copper strip (3) is fed into the channel. The copper strip is melted in a narrow region transversely of the foil by an electron beam gun (32) and it is bonded by diffusion to the still solid niobium. The electron beam may be directed either on to the copper or niobium face of the strip and it may be deflected in steps over the width of the strip or guided linearly across its width. Alternatively niobium strips 4, 5 Fig. 5, and a copper strip 3, are fed simultaneously into a vacuum housing (12<SP>11</SP>), Fig. 6 (not shown), where electron beams 7<SP>1</SP>, 8<SP>1</SP> melt the copper in narrow regions b to bond it by diffusion to the niobium strips 4, 5. Recesses 38, 39 reduce heat-transfer to the roller 10<SP>11</SP>, which is usually cooled by water. The electron beams 7<SP>1</SP>, 8<SP>1</SP> may be directed at the strips 4, 5 and the copper melted by heat conduction. The composite strip 50, Fig. 7, is passed through a fusion electrolysis installation, which comprises an electrolyte housing 40 and a furnace 51. A connection 52 is provided for a vacuum pump and a connection 54 for the supply of protective gas. The electrolyte is alkaline niobium fluoride at a temperature of about 740C. With a current density of about 40 mA/cm<SP>2</SP> between an anode 47 and the strip 50, which serves as a cathode, niobium is deposited at a rate of about 0À6 Ám./min. The strip made by the foregoing methods is bent to bring the niobium strips 4, 5 into abutment and they are welded together, preferably by an electron beam 58. An alternative form of strip is made by filling a channel-section niobium tape (82), Fig. 9 (not shown), with copper and rolling it to the required thickness prior to bending and welding. The niobium layer 2, Fig. 8, may be located either on the inside or outside of the tubular conductor. The copper may be replaced by aluminium or nickel or their alloys.

Abstract: 1,014,758. Welding by pressure. ALLMANNA SVENSKA ELEKTRISKA A.B. Oct. 16, 1962 [Oct. 19, 1961], No. 39059/62. Heading B3R. In resistance welding workpieces of material which is difficult to weld the workpieces are pressed together during resistance heating with a low pressure of 0À5-3 kiloponds per mm.<SP>2</SP> which is followed when the surfaces are plastic by a higher pressure of 8-25 kiloponds per mm.<SP>2</SP>. In welding two pieces 11, 12 of titanium, copper or zirconium the pressure is initially low, preferably 1-2 kiloponds per mm.<SP>3</SP> and is suddenly increased to 10-20 kiloponds per mm.<SP>2</SP> when the pieces reach the plastic state detected by a device 13. The current is cut off when the pressure is increased or possibly earlier or later. When the pieces abut over an area smaller than their cross-section an initial higher pressure is followed by the low value until the plastic state is reached and then the pressure is increased to a value similar to that initially employed. The Specification refers to flash and projection welding.
