IPC: B24B53/07
Filed: 1974-04-29
Abstract: 1440868 Dressing and sharpening grinding wheels ERNST WINTER & SOHN 29 April 1974 [27 April 1973] 18610/74 Heading B3D In the dressing and sharpening of a grinding wheel, the wheel is dressed simultaneously whilst rotating, by two rotating rollers one of which has a peripheral speed greater than the peripheral speed of the grinding wheel and the other has a peripheral speed less than the grinding wheel such that the two rollers have equal dressing speeds and opposite directions of cut. In the embodiment described the two rollers R 1  and R 2  are applied to the rotating grinding wheel "S" the rollers rotating in the same directions but at different speeds NR 1  and NR 2 . The peripheral speed of the roller R 1  producing a peripheral force F 1  in the opposite direction to the peripheral force F 2  produced by the roller R 2 . The rollers R 1  and R 2  may be of the same or different sizes and may be driven at different or the same speeds by belt and pulley drive system A, C, D, 4 and 5 from a motor M. During the operation the grinding wheel may be axially reciprocated to produce a transverse motion relative to the rollers. Numerical values of speeds, pulley sizes &c. one given in the Specification to produce optimum dressing and sharpening conditions in the terms of cutting force, wheel speed and temperature.

IPC: H01R4/20
Filed: 1968-04-19
Abstract: 1,209,089. Making electrical connectors. THOMAS & BETTS CORP. 19 April, 1968, No. 18626/68. Heading B3A. [Also in Division H2] An electrical connector, formed from a strip of sheet metal 42 by a series of stamping and bending operations (fig. 3), comprises a terminal portion, and a tubular portion formed by bending over the rectangular portion of sheet metal. The edges of the rectangular portions are bevelled, so that opposite edges form a seam 40 (Fig. 9) which does not increase the thickness of the tube walls. Electrical connection is made by force fitting a wire or cable into the tubular section, and to facilitate this a flared shoulder portion 50 is incorporated. In accordance with the invention, the sheet is provided with corner extensions 48, so that no V-shaped gap appears, in the circumference in the region 58, as happens in the prior art (Figs. 1 and 2,-not shown), when the tube is flared. The size of the extension may be varied to give maximum overlap (Fig. 11, not shown), or minimum overlap, this latter resulting in a butt seam (Fig.13, not shown). Grooves 36 are cut in the sheet-metal to give an enhanced friction grip on the wire. A metal sleeve 54 covers the connection and is itself covered by a nylon sleeve 56

Abstract: The invention comprises 4-phthalimido benzoquinone, its N-b -hydroxyethyl derivative; 4-phthalimido-a - and 4-phthalimido-b -naphthoquinone; and a compound of the formula <FORM:0735048/IV (b)/1> together with a process for the synthesis of 4-substituted phthalimides which comprises reacting a diazo compound of 4-amino-phthalimide or of its N-b -hydroxy ethyl derivative with a quinone or acrylonitrile, preferably in the presence of a copper compound, e.g. cupric chloride, as catalyst.  Specified quinones which may be used are quinone, chlorobenzoquinone, 2 : 3 - dimethylbenzoquinone, tert.-butylbenzoquinone, phenylbenzoquinone, a - and b -naphthoquinone, 1 : 2 - naphthoquinone - 4-sulphonic acid, 1 : 4-naphthoquinone-6-carboxylic acid and -6-sulphonic acid, 5 : 8-quinoline quinone and the indophenols.  In examples: (1) 4-amino phthalimide is diazotized and added to a stirred suspension of quinone in aqueous sodium acetate containing acetic acid, when 4-phthalimidobenzoquinone is precipitated; (2) diazotized 4-aminophthalimide is treated with sodium acetate solution and then added to a stirred ethanolic solution of a -naphthoquinone, when 4-phthalimido-a -naphthoquinone is precipitated.  Catalytic hydrogenation and subsequent dehydration of the product yields b -(4-phthalimido)-naphthalene; (3) as in (2), but replacing the a -quinone by b -naphthoquinone in glacial acetic acid, when 4-phthalimido-b -naphthoquinone is obtained; (4) as in (3). but using the potassium salt of 1 : 2 - naphthoquinone - 4 - sulphonic acid in aqueous sodium acetate; (5) 4-aminophthalimide is diazotized and, after excess nitrous acid has been destroyed with amino sulphonic acid, treated with acrylonitrile in acetone.  Cupric chloride is added, when nitrogen is evolved and a -chloro-b -(4-phthalimido)-propionitrile separates.  Removal of HCl with a tertiary amine, followed by saponification, yields 3 : 4-dicarboxycinnamic acid; (6) 4-amino-N-b -hydroxyethyl phthalimide is diazotized and added to a stirred suspension of benzoquinone in aqueous sodium acetate yielding 4 - benzoquinonyl - N - b  - hydroxyethyl phthalimide.
