Title: Novel or improved means for use more especially in displaying and changing musical score
IPC: G03B21/00
Filed: 1942-11-26
Abstract: 562,385. Electric signalling systems. CARRINGTON, B. N. Nov. 26, 1942, No. 1676]. [Class 40 (i)] [Also in Group XX] In an arrangement for displaying information, miniature reproductions in the form of transparencies are mounted in discs or drums, which by means of an electrical dialling system may be selected and moved to bring a desired transparency into position to be proprojected on a screen. The arrangement is intended particularly for displaying musical score to the members of an orchestra, the projectors of the various performers being controlled from a central point. In addition, each projector may be subject to local control by the performer either electrically or, according to the Provisional Specification, directly by hand. As shown, ten discs 25 which are apertured to receive the transparencies are supported one above the other on the head 60 of a screw-sleeve 27 which is held against rotation on the shaft 26 and is engaged by a nut 68 integral with a toothed wheel 71, so that rotation of the latter by electrical impulses lowers the discs until a selected one lies in the focal plane of the projector comprising a lamp 65, condenser 84 and lens 88. The selected disc is now coupled to the shaft 26 by a projection 89 entering a notch 90 and is rotated by a toothed wheel 94 on the shaft in response to further impulses to bring a desired transparency in front of the condenser 84. A notched guard-plate 91 co-operates with peripheral slots 92 in the discs to allow rotation of only that disc which lies in the focal plane. The impulse transmitter comprises two independent dialling plates 21, 22 for rotating corresponding cam-wheels 31, 32 which at contacts 37, 38 and 47, 48 control the stepping magnets of the wheels 71, 94. Impulses are sent during the forward movement of the dials, which are then maintained in the displaced positions until released by means of a push button 56. The latter disengages a brake 50, 51 to free the wheel 31 and energizes a magnet 45 which releases a detent 41 holding the wheel 32. During the return of the wheels 31, 32, further impulses are sent, and the operation of reversing magnets in circuit with magnet 45 makes these effective in restoring the wheels 71, 94 to their normal positions. in a modification, the transparencies are carried by a pair of drums which are rotated and moved axially to bring a desired transparency into position for projection.

Abstract: 1386692 Manure spreaders TEXAS INDUSTRIES INC 12 April 1972 [15 April 1971] 16958/72 Heading AID A spreading implement includes a mechanism which produces a relative movement between the base of a hopper 2 and an internally mounted shaft 12 carrying flails or similar ejectors 16 as the hopper 2 is emptied during use and hence maintains contact between the ejectors and the remaining material in the hopper. In one embodiment, the mechanism includes two springs 7, mounted on an axle 4 of a pair of ground wheels 3, which raise the hopper as the load decreases and this movement is transmitted via a linkage 8, 9, 10, 11 to the rear end of the shaft 12 which moves in a vertical slot 13 formed in the rear walls of the hopper. The height of a hood 17, attached to a side wall of the hopper via hinges 18 progressively increases towards the rear to allow for the variations in the shafts inclination. In another embodiment (see Figs. 4 and 5, not shown) the shaft 12 is horizontally mounted between front and rear supports and the hopper, which has vertical slots in its front and rear walls for the shaft, is raised and lowered by two pairs of compression springs. Alternatively only the lower part of the hopper may be moved vertically in response to the degree of compression of the spring mechanisms.
