Title: Improvements relating to cranes
IPC: B66C23/10
Filed: 1937-10-07
Abstract: 503,100. Jib cranes. LAINE, N. Oct. 7, 1937, No. 27303. [Class 78 (iv)] In the lover-luffing of cranes, in which a compensating movement is applied to the lifting-rope at or near its driving-point, a flexible member is employed which extends between a point movable with the jib and a curved member on the frame, so that the variation in length from the point on the jib to the point of contact with the curved member is proportional to the necessary compensating movement, such variation being imparted by transmission mechanism to the lifting- gear. Fig. 4 shows one construction in which a flexible member 1, connected to a point a<3> on the jib tail, is passed round a curve formed of rollers 2 on the framing before passing round the guide pulley 3 to differential-gear as set out below. In a modification the rollers 2 are replaced by a pulley under which the rope 1 passes. This pulley 4, Fig. 7, is rotated when the jib is luffed and imparts a compensating movement to the lifting-drum 16 by driving the planet pinions 14 through the gearing 10, 11. The hoisting-drum is connected to the ring 15, and the sun-wheel 18 is fixed during the luffing-operation. Various other modifications are described in which the flexible member engages the. main arm of the jib. Fig. 11 is one example in which the flexible member 1 connected to the jib at a<2> passes over the curved surface represented by the pulley 4. Another modification is suitable for jibs operated by fluid-pressure rams.

Title: Manufacture of transparent discs
IPC: C09K3/18
Filed: 1934-09-24
Abstract: Transparent non-misting partitions suitable for windows for gas masks or for use in viewing, measuring, or optical instruments, are prepared by completely saturating a foil of regenerated cellulose with a liquid so that the foil cannot swell further, and fastening it while still saturated to a frame-like structure so that contraction on drying is prevented or minimized.  In a modification, the saturated foil is fastened over the whole of the contacting surface of a transparent rigid carrier such as a sheet of glass, safety glass, celluloid, or the like.  A suitable adhesive in this case is a solution of gelatine in dilute acetic acid and alcohol.  The foil is preferably saturated by immersion in water at about 50 DEG  C. for 15 minutes.  The Specification as open to inspection under Sect. 91 refers to the preparation of transparent partitions from cellulose derivatives.

Feeding and driving means.-Relates to driving-mechanism for films, particularly in sound-recording and reproducing apparatus. According to the invention, the film is drawn from a source of supply such as a reel, and is delivered directly without tension to a feed-device driven at a constant speed. In the machine shown, which comprises photoelectric sound-reproducing apparatus, a sound-record film is drawn from a reel 11 by a sprocket wheel 19, driven by a motor through a shaft 21 and worm gearing, and after passing without tension to a constant speed feed-sprocket 20, by which it is fed past the reproducing-device, the the film again engages the sprocket 19 and passes to a take-up reel 12. The usual tensioning devices 34 are arranged as shown. The sprocket 20 is mounted on one end of a shaft 24, surrounded by a sleeve 28 which carries a spider 26, this being connected by springs 27 to a flywheel 25 fixed on the shaft 24. The shaft 21 drives the sleeve 28 through worm gearing, and a uniform drive is thus transmitted to the shaft 24 and its sprocket 20 through the resiliently coupled flywheel. Damping springs (not shown) surround the springs 27, as a further means for eliminating vibrations. A shield 33 is arranged tangentially to the wheel 19, to prevent the film if it should break, from winding round the wheel. Specification 295,603, [Class 40 (ii), Phonographs &c.], is referred to.
