Abstract: 473,741. Stage-lighting apparatus. BRENT, J. Dec. 10, 1936, No. 33890. [Classes 75 (iii) and 75 (iv)] [Also in Group XV] Spot-light apparatus is arranged in the footlights or substantially centrally above the proscenium opening to illuminate and throw a shadow of a performer onto the stage background, and remote control means, actuated, for example, from the wings, is provided for altering the direction of the beam to follow the movements of the performer, and, if desired, also to alter the characteristics of the beam. The spot-light comprises the lantern A, the casing D of which is adjustably but rigidly mounted. by bolts and nuts F, in a fork E rigid with a bolt e and wheel J rotatably mounted in a bracket G fixed in a trough at the front of the stage adjacent the footlights Z, or on battens centrally above the proscenium opening. The casing D is rotated to vary the direction of the spot-light beam through a band M passing around the wheel J along the trough over suitable guide pulleys and around an operating wheel N located in the wings. The usual colour disc O of the spotlight is urged to rotate by a mechanical motor R but is normally held locked by a spring-biassed trigger U engaging one of four stops V<1>, V<2>, V<3>, V<4> corresponding to the four-colour screens P<1>, P<2>, P<3>, P<4>, the trigger being released to permit the colour disc to rotate through a Bowden wire X also controlled from the wings by a handle Y fixed on the wheel N. Alternative transmission means for rotating the lantern and for changing the colour of the light may be used. For example, the colour disc may be replaced by a sliding panel carrying the colour screens urged to one terminal position by a spring and retracted against the action of the spring to the different colour operative positions through a cord extending to the wings, these positions being determined by a trigger engaging stops on the panel, one stop for each colour, the trigger being also controlled from the wings, e.g. through a Bowden cable.

Title: Dyeing and or printing of cellulose acetate
IPC: D06P5/22
Filed: 1963-08-28
Abstract: The invention comprises cellulose acetate containing fabrics which are coated with hydroxyethylcellulose and a process for producing such fabrics.  The cellulose acetate fabric is treated with an alkaline solution of hydroxyethylcellulose, preferably containing an amphoteric detergent, thereafter coagulating and regenerating hydroxyethylcellulose using neutral, alkaline or acidic reagents yielding an insoluble film of hydroxyethylcellulose on the fabric. The solution used preferably contains 2-8% hydroxyethylcellulose, 5-9% of alkali metal hydroxide, 0.1-1% of amphoteric detergent and the remainder is water.  The solution is applied to the fabric by spraying or padding and 10-100% on weight of fabric is used.  The regeneration may be preceded by a steaming process at 200-250 DEG F., which gives better penetration.  Many regenerants are specified a plurality of which may be used together, the process includes various washing steps and is finished by drying the coated fabric at neutral pH values on a tenter, loop dryer or drying cylinders.ALSO:The invention comprises a process for improving the dye affinity of yarns and fabrics containing a proportion of cellulose di-or tri-acetate. The cellulose acetate containing material is treated with an aqueous alkaline solution of hydroxyethylcellulose after which the hydroxyethylcellulose is converted into a water-insoluble film bonded to the material by regeneration and coagulation using neutral, acidic or alkaline precipitants.  The film of water-insoluble hydroxyethylcellulose produced in the materials treated supplies a source of hydroxyl groups with which reactive dyes especially are able to react, other dyes applied by conventional techniques are vat, azoic, naphthol, chrome, direct and sulphur dyes.  In the preferred process the alkalene hydroxyethylcellulose solution also contains an amount of an amphoteric detergent.  Heat alone may be used as a regenerant, the process for precipitating the film on the fabric or material involves various washing processes.

Title: Improvements in arrangements for eliminating disturbances in radio receiving sets
IPC: H03G11/00
Filed: 1935-12-13
Abstract: 445,763. Wireless receiving systems. NAAMLOOZE VENNOOTSCHAP PHILIPS' GLOEILAMPENFABRIEKEN, Emmasingel, Eindhoven, Holland. Dec. 13, 1935, No. 34653. Convention date, Feb. 1. [Class 40 (v)] In order to eliminate the effect of disturbances in a radio receiver, a switching device disables the low frequency amplifier upon receipt of a disturbance, the impulse produced by said device being neutralized by a compensating circuit. In one embodiment, an anode bend detector D, Fig. 1, feeds a low frequency amplifier V through transformer T1 and an auxiliary rectifier G fed from a coil W coupled to the detector input circuit T operates a relay R to open a contact S in the detector anode circuit when a disturbance of above a predetermined amplitude is applied to the valve G. The said amplitude is determined by the grid biassing source Eg2 of the valve G. The impulse produced in the grid circuit of valve V by the switching operation is neutralized by a compensating circuit comprising a transformer T2 whose secondary S2 is in the grid circuit of valve V and whose primary circuit containing a resistance R1 and anode source Ea is opened by the contact S. In a further embodiment, Fig. 2 (not shown), the auxiliary rectifier produces a disabling grid bias for a low frequency amplifier which is also applied to a compensating valve the output circuit of which is connected in push-pull with the disabled valve. In a third embodiment, a low frequency coupling transformer, Fig. 3, comprises a primary 1, 1 split secondary 2, 2 and a saturating winding 3, 3 controlled by the auxiliary rectifier to lower the efficiency of the transformer upon receipt of a disturbance. The two halves of the secondary 2, 2 have equal and neutralizing impulses induced by the sudden change in magnetization. The auxiliary rectifier may be fed from an auxiliary receiver tuned to a channel other than that being received by the main apparatus or from an aperiodic receiver.
