Title: Improvements in advertising and display devices with moving effect
IPC: G09F13/00
Filed: 1936-01-31
Abstract: 454,293. Changing signs. SHIGLEY, W. W., 69, Halsey Street, Brooklyn, New York, U.S.A. Jan. 31, 1936, No. 2985. [Class 3 (i)] Incandescent or electric discharge lamps 5 on a plurality of radial arms 1 are rotated by a motor 4 through pinions 23, 24. The lamps 5, arms 1, and pinion 23 are carried by a disc 2 loosely journalled on the motor shaft 3, and rotation is imparted to the disc 2 by a brake block 36 slidably mounted on the disc 2. The block 36 may be pressed by a spring to give a constant frictional drag on a drum 35 fixed to the shaft 3 or may be normally retracted by an adjustable spring 38 and be pressed against the drum 35 by centrifugal force acting on a mass pivoted to the disc 2 and bearing on the rod carrying the block 36. The effect of the latter arrangement is to cause the disc to be more closely held to the shaft 3 the faster it rotates. The disc 2 is furnished with a brake ring 14 on which bears a brake shoe 27 carried by a rotatable shaft 29 which is oscillated at intervals by a cam 33 driven by the motor 4. The ring 14 acts also as a contact for leading current to the lamps 5, the contact brush 16 being connected to a transformer 17. The lamps 5 and arms 1 may be balanced by a mass 45. In action the lamps 5 will at first describe a circle, and then as the speed increases motion will be imparted by friction to the disc 2, giving the illuminated path a changing and more or less complex form. In a modification the shaft 3 is driven by a belt From the motor, and the brake mechanism is re-arranged. Two discs 3 may be mounted to face in opposite directions and be alternately braked by cams carried on a single shaft oscillated by a cam driven from the motor

Filed: 1940-03-02
Abstract: 539,327. Artificial filaments and threads. BRITISH CELANESE, Ltd. March 2, 1940, No. 3942. Convention date, March 2, 1939. [Class 2 (ii)] Artificial filaments, threads, yarns and the like having a reduced tendency to wear parts of the machinery with which they come in contact, have distributed within them a finely divided material having a refractive index not greatly different from the base material ; this ensures that the lustre or transparency is not greatly different from that of the ordinary product. The amount of the finely divided material is of the order 0.5 to 1.5 per cent of the weight of the base material, and in the case of products made from cellulose acetate the finely divided material may be silicon dioxide, hydrated aluminium oxide or aluminium hydrate and calcium magnesium silicate. In one example, aluminium hydrate, cellulose acetate and acetone are kneaded in a heated kneading machine to form a stiff doughy mass which is then worked between heated malaxating rolls until it is substantially free of acetone. The resulting sheet is broken into chips or pieces which are put into the spinning solution of cellulose acetate in acetone. The solution is filtered and extruded through the spinning jet into a heated evaporative atmosphere.
