Patent GB-1247510-A (GB)
Title: Improved printer
Inventor: KRAUTWALD MANFRED
IPC: B41J9/10
Filed: 1970-09-03
Abstract: 1,247,510. Selective printing. INTERNATIONAL BUSINESS MACHINES CORP. 3 Sept., 1970 [16 Sept., 1969], No. 42093/70. Heading B6F. Hammer impression.-A chain printer, having two or more single hammers travelling along the printing line, has the print hammers 9 (only one of which is shown) pivoted on an axle 11 mounted on a bar (12, Fig. 1), each end of which is connected to one end of a leaf spring 13, the other end being connected to a stationary frame member 8. The bar (12) and frame 8 may be interconnected by rigid members instead of leaf springs to form a similar parallelogram system, which provides arcuate movement of the axle 11 which at all times remains parallel to the line of printing. The pivoted armature 14 of an electromagnet (10, Fig. 1) abuts a push rod 15 which contacts the print hammer 9 at its other end. A guide tube 16 for the rod 15 is pivoted at 17 to the frame 8 and is supported at the hammer end on a bar (19) fixed to bar (12). A finger (9a) of print hammer 9 co-operates with an absorbing bar (20) mounted on frame 8. A finger 9b of the print hammer 9 abuts a bolt 21 inserted in a bore hole in the bar (12) and is acted upon by compression spring 22. As the hammer moves to each of its four positions A, B, C, D, the position of the push rod 15 with respect to the axle 11 mounted on the parallelogram system is such that the print hammer 9 is pivoted through an angle, so that the displacement of an impact surface 9c from the printing line is maintained substantially constant.

Title: A process for the production of carbodiimides
Filed: 1962-11-12
Abstract: Carbodiimides are prepared by reacting an organic isocyanide dichloride with the hydrochloride of a primary amine at a raised temperature. The reaction of a mono-isocyanide dichloride with the hydrochloride of a primary monoamine yields a carbodiimide of the formula R1-N = C = N-R, while the reaction of a bis-isocyanide dichloride with the hydrochloride of a primary monoamine, or of a mono-isocyanide dichloride with the hydrochloride of a primary diamine, yields a bis-carbodiimide of the formula R1-N = C = N-R-N = C = N-R1.  In these formulae R may be an alkyl, alkylene, phenyl, phenylene, cyclohexyl, cyclohexylene, chlorophenyl, chlorophenylene, nitrophenyl, nitrophenylene, alkoxyphenyl, alkoxyphenylene, benzyl, benzylene, diphenyl, diphenylene, benzoyl, benzophenone, naphthyl or naphthylene group and R1 may be an alkyl, cycloalkyl, aryl, alkoxyaryl, chloroaryl or nitroaryl group. Reference is made also to the production of polycarbodiimides from bis-isocyanide dihalides and hydrochlorides of primary diamines. The reaction may be effected at 100-200 DEG  C. in a solvent, a number of which are specified. Examples are given in which (1) phenylisocyanide dichloride and aniline hydrochloride yield diphenyl carbodiimide, and 4-chlorophenylisocyanide dichloride and aniline hydrochloride yield (4-chlorophenyl)-phenyl carbodiimide; (2) 2,4,6-trichlorophenylisocyanide dichloride and 4-chloraniline hydrochloride yield (2,4,6-trichlorophenyl) - (4 - chlorophenyl) carbodiimide; (3) phenylisocyanide dichloride and 4-nitroaniline hydrochloride yield (4-nitrophenyl)-phenyl carbodiimide.

Abstract: 1531994 Clamps DONALDSON CO INC 24 Oct 1975 [15 Nov 1974] 43728/75 Heading E2B [Also in Division F2] A band 21 of ductile metal, e.g. "dead soft" tempered stainless steel, for joining overlapping tubes 35, 36 e.g. of an exhaust system, has a length slightly less than the circumferences of the tubes so that on being clamped around their junction it is stretched beyond its elastic limit and conforms to the tube contours to seal them. The ends 24 of the band 21 are bent to provide clamping flanges that are reinforced by spot- or seam-welded bars 26. The ends 24 of the band may be doubled back or completely wrapped around the bars 26 before welding. Two bolts or a single U-bolt 32 passing through bores 31 in the end flanges 21, 26 provide the clamping means for improved clamping. Sleeves may be secured to the reinforcing bar 26 against which the nuts 34 bear, the bores 31 in the sleeves and bar being only just large enough for the bolt or bolts to pass. The bends 30 at the ends 24 may be perpendicular to the band edges 22, 23 or for improved contact with tubes of different diameters may be slightly inclined. For the same reason the bars 26 may have slots between the bores 31 to enable them to deform in zig-zag fashion, or else they may have a slight V- shape on the sides that face the tubes 35, 36. A compressible packing strip 37 is positioned between the ends 21 as a further seal.

Title: Method for sharpening rock drill bits and device therefor
IPC: B24B3/33
Filed: 1963-11-08
Abstract: A method of sharpening a rock drill 17 having four cutting edges constituting two pairs of diametrically opposed rearwardly inclined aligned cutting edges 19 comprises applying an annular rotating cathode tool surface 13 simultaneously to two anodically connected aligned cutting edge surfaces, one on each of two diametrically opposed cutting edges, one other cutting edge entering the centre of the annular electrolyte being fed to the cathode tool cutting edge surface interface.  The surface 13 is of annular form <PICT:1059526/C6-C7/1> and may be abrasive, such as diamond particles embedded in metal or non-abrasive.  The surface is formed on a ring 30 secured to a hub 10 rotatable in bearings by a belt drive 12.  The annular form of the surface permits a cutting edge 18 to be received in a space 14 within the hub while the rearwardly inclined surfaces of two aligned cutting edges of the drill are engaged with the surface 13.  The hub 10 has a contact layer 15 engaged by a brush connected by a variable device 24 to a source 13 of current also connected to the drill 17.  Electrolyte is supplied to the surface 13 from a tube 21.  When the diamond grains on the surface are worn, the current may be reversed to disintegrate the metal in the surface 13 to expose more of the diamond grains.  In other embodiments, the surface may be conical or curved.
