摘要： 10,760. Davis, W. M. May 2. Piano-players combined with gramophones.- An automatic piano-player having a tune-sheet recording-device is coupled with a gramophone so that as a song or solo is being recorded in the phonograph the accompaniment is being recorded on the piano - player tune - sheet, whereby when reproducing the records together, the accompaniment is played upon the pianoplayer. The piano 1 is provided with any ordinary recording-means 2 for perforating the music roll 3, which is passed from a roller 4 to a roller 5 over a tracker board 6. The gramophone turn-table 10, while the song is sung into the horn 8, is rotated by a bevel-wheel 14 from a motor 11, which simultaneously drives the music roll 3. For starting both reproductions together, while recording, three notes 15, Fig. 3, are softly struck on the piano so that, when the pianist hears these notes given out by the gramophone, he starts the piano player.

摘要： 11,498. Rusett, E. W. de, and Davis, W. E. June 25. Cattle ships.-Relates to means for facilitating the shipping and unshipping of the stanchions and boards, and is shown as applied to wooden boards. It is, however, equally applicable to round or other shaped parts of wood or metal. As shown in Figs. 1 and 2, the stanchions are hollow and fit into swivelling head sockets 2, attached to an overhead beam 4 secured to the deck. The sockets for the side or breast boards 6 are formed of side plates 7 bolted to the stanchion. These plates are slotted to receive the ends of the open rings 10, which rest on the boards under the horns 11 and prevent the boards from rising out of their sockets. By sliding the ends of the rings up the slots, the rings can be swung up clear of the horns, to allow the boards to be unshipped. In a modification of this arrangement, shown in Fig. 4 , one of the side plates is bent at 21 to form box-like sockets. As shown in Fig. 1, the footboards 12 are secured in the same way as the breastboards. The foot of the stanchion fits in a socket 14 made so that dirt can easily be removed. An open ring with its ends in the side plates prevents the stanchions from rising. Fig. 5 shows a plan of corner sockets for holding foot or middle boards. The outside plate is bent round the stanchion, and there are two inside plates, all three being secured by one bolt. The stanchion may be prevented from.rising by a ring engaging the head socket in one of the ways shown in Figs. 7, 7 , or 8. Figs. 10 and 11 show two methods of arranging rings for preventing the vertical division boards from rising.

摘要： Title: Process and Apparatus for Monitoring Length and Diameter of Helical Corrugated Pipe An apparatus and process for monitoring the diameter and length of a helical corrugated metal pipe (21) while the pipe is being formed from a strip of corrugated sheet metal. The apparatus includes a sheet metal strip length sensor located on a corrugated helical metal pipe forming machine. A series of length sensors (ER) are located along a formed pipe axis and are responsive to presence or absence of the formed pipe at their locations. A digital computer (39) receives information from the sensors and is connected to various peripheral devices. The process of monitoring the diameter and length of the pipe (21) involves measuring sheet metal strip length, determining presence of formed pipe at the various length sensor locations, and determining pipe length and diameter as a function of sheet metal width and length of sheet metal strip used.
