Title: Device for the continuous manufacture of saw blades
IPC: B23D63/00
Filed: 1957-05-31
Abstract: 852,834. Making saws; reciprocating filing. STALSAGAR A.B. May 31, 1957 [May 31, 1956], No. 17462/57. Classes 83 (2) and 83 (3). [Also in Group XXIII] In a machine for continuously making saw-blades from strip by cutting notches in the strip to form saw-teeth, the tool, e.g. a cutting- tool, grinding-wheel or file is reciprocated perpendicularly to the blank and is fed parallel to the blank and in a transverse direction so that a number of cuts made during the formation of each tooth-gap. The machine may include a tooth-setting device. The strip 8 is passed through a guide 7 fixed to the base and traversing an aperture in a plate 16 mounted on pivots 14, 15, on the outer ring 13 of a ball-race. The inner ring 12 rotated by an electric motor 4 carries eccentrically, a pin 46 which oscillates an arm 44 engaging grooves in backing-ring portions 47, 48, secured to the plate 16. The plate 16 is reciprocated about the inner ring 12 by a cam 30 driven by an electric motor 5, and about the pivots 14, 15, by a member 35 ball-jointed, to the cam 30 away from the axis of the cam 30, and engaging a bevelled surface 36 of the plate 16. A spring 37 supports the plate 16, which moves through a substantially rectangular path. The upper portion of the path is governed by engagement of an oblique surface 67 of the plate 16 with a parallel surface on an adjustable block 66. During the movement of the plate 16, ball-races 24, 25, secured to the plate grip and feed the strip 8. During the upward movement of the plate 16, and thus of the arm 44, a tool 42 secured to the arm 44 and oscillating therewith at about 1500 strokes per minute, cuts a notch in the strip 8. The cutting-face of the tool 42 is guided in the grooves in the ring portions 47, 48, which also support the strip 8 adjacent the cut. The upper-face of the tool 42 is curved to the same radius as the ring portions 47, 48. After the notches have been cut, the strip 8 passes to a tooth-setting device consisting of opposed punches 71, 72, Fig. 9, secured to a slide 73 which, when the strip 8 is stationary, is reciprocated by arms 79 on a shaft 19 driven by the motor 5. The punches set adjacent teeth in opposite directions, and the timing of the machine leaves each third-tooth unset. The slide 73 is spring- loaded to a central position, in which the strip 8 can pass between the punches.

Abstract: 546,596. Crotonic acid betaine compounds. ROCHE PRODUCTS, Ltd., BERGEL, F., COHEN, A., and HINDLEY, N. C. Dec. 10, 1940, No. 17527. [Class 2 (iii)] Crotonic acid betaine compounds and quaternary ammonium compounds of similar constitution are prepared by the condensation of malonic acid with a quaternary ammonium salt of the general formula where R, R<SP>1</SP>, and R" are alkyl aryl; or aralkyl groups and X is halogen. The condensation is preferably carried out in the presence of a base such as pyridine. In examples (1) a reaction mixture comprising malonic acid, anhydrous pyridine and the hydrate of trimethylethylal-ammonium chloride is heated on the water bath, evaporated to dryness, and purified by. fractional precipitation to give crotonic acid betaine chloride. (2) Triethylethylalammonium chloride, malonic acid and dry pyridine are heated on a hot water bath and worked up as in example (1) and the product purified by formation of a reineckate to form γ-carboxyallyl-triethyl ammonium chloride. (3) Trimethyl-#-propional-ammonium chloride, malonic acid and dry 'pyridine are treated as in example (1) to produce #-carboxy-# γ-#- butenyltrimethyl ammonium chloride.
