Title: Improvements in or relating to a device for oscillating the die of a continuous casting unit
IPC: B22D11/053
Filed: 1962-04-06
Abstract: 937,140. Continuous casting. CONCAST A.G. April 6, 1962 [April 6,1961], No. 13289/62. Class 83 (1). A device for oscillating the die of a continuous casting unit comprises two working cylinders 6 with pistons 7 which support the die table 4 and are located within end frames 2. Separate control cylinders 8 connected to each working cylinder 6 by conduit 11 have three pistons therein on a common piston rod, one end of which is articulated, within guides 20, to a control lever 12 and the other end biased by spring 21. One end of each control lever carries a feeler roll 14 which follows a cam disc 15 attached to a driven shaft 16. The other end of the lever carries an adjustable slide 13 which bears against part 13<SP>1</SP> within the frames 2 and which is provided with a scale. With the rotation of the shaft and cam disc 15 pivoted movements are imparted to the control lever 12 which reciprocate the pistons in control cylinders  8 and permits pressure fluid to be admitted to and discharged from working cylinders 6. The die table is thus raised and lowered, its movement in turn effecting movement of the pistons in the central cylinders by further pivoting of the levers 12 about the slide 13. The feeler rolls 14 are maintained in contact with the cam discs 15 by the spring 21, and the stroke of the control pistons, for a given shaft speed, may be varied by adjustment of the slide 13 along the scale.

Title: Improvements in or relating to thieno-benzothiapyran derivatives
Inventor: RENZ JANY
IPC: C07D495/04
Filed: 1962-04-17
Abstract: The invention comprises:  (1) compounds A wherein R16 is methoxy or methylmercapto; (2) the preparation of compounds of general formula <FORM:1012315/C2/1> wherein R16 is an alkoxy or alkylmercapto radical (1-4 C) by condensing 2 - mercaptothiophene with a 2-bromo-5-R16-benzoic acid and cyclizing the resulting 5-(2-thienyl)-5-substituted-thiosalicylic acid with a polyphosphoric acid.  An alternative condensation starting from 2-bromo-thiophene and a thiosalicylic acid and cyclizing with concentrated sulphuric acid is mentioned.  2-Bromo-5-methylmercapto-benzoic acid is obtained by the action of dimethylsulphate on the 5-mercapto-compound which is produced by reduction of 2-bromo-benzoic acid 5-sulphochloride, itself obtained by sulphochlorination. Specification 1,012,314 is referred to.

Title: Improvements in cascade development of electrostatic images
IPC: G03G15/08
Filed: 1961-04-14
Abstract: 986,844. Electrophotographic development. RANK-XEROX Ltd. April 14,1961 [April 15, 1960], No. 13464/61. Heading G2H. The electrostatic image on a rotatable xerographic cylindrical member is developed by cascading granular developer over the outer surface so that the developer is directed to the surface tangentially with a speed greater than that of the cylinder at the point of contact, and allowing the developer to fall away from the cylinder at a point lower than the point of contact. Preferably the point of contact is at a position below the highest point of the cylinder and the speed of the developer stream is sufficient to maintain a speed exceeding that of the cylinder whilst passing over the highest point. As shown an image of a continuously moving film 13 is projected on to the charged photoconductive surface of the continuously rotating drum 10 and the electrostatic charge image so produced is made visible by the developer (toner and carrier) applied by the shoot 25 fed by the hopper conveyer 23. In an alternative arrangement (Fig. 2 not shown) a horizontally moving conveyer fed by a hopper propels developer over a deflecting guide plate whence it is applied tangentially to the cylinder. As a further modification the Specification suggests applying the developer tangentially with the help of air jets. A rotating brush 20 removes residual developer from drum 10 before re-use.
