IPC: A01K5/01
Filed: 1988-03-14
Granted: 1991-10-30
Abstract: The tying device is used to tie animals in a cattle shed individually or in groups of two to an animal-separating frame (1) above a lying area (13) and in front of a continuous manger (10). A manger-side support post (3) on the animal-separating frame and a boundary tube (7) running along the manger are presupposed. The animal-separating frame (1) is anchored to the support post (3), offset towards the feeding trough, and this support post has at the upper and lower ends in the post axis accessible guides (22, 23) for receiving a manger-dividing member (30). This permits a modular construction of a basic item of equipment, in particular various variants as regards the division of the manger and the position of the boundary tube (7). A separating plate (40) can advantageously be mounted horizontally rotatably on the pivotable manger-dividing frame (30) and can be coupled via a gear (43, 44) in such a way that, with a pivoting of the dividing frame, the plate (40) is forced to fold upwards. This permits, on the one hand, individual feeding by means of complete trough subdivision and, on the other hand, unobstructed and continuous cleaning of the manger (1). <IMAGE>

Granted: 1992-09-02
Abstract: A process is provided for the preparation of the dimer, dichloro-[2,2]paracyclophane, which is useful as the starting material for the deposition of conformal parylene coatings employed, for example, in the electronics industry for the protection of various sensitive electronic components. The process avoids the normally low yields of chlorinated dimer formed by the chlorination of 2,2-paracycophane and instead utilizes the Hofmann elimination of 2(3)-chloro-p-methylbenzyltrimethylammonium hydroxide by conducting the elimination reaction under carefully controlled conditions of reaction temperature and profile, reaction feed configuration, water concentration in the reactor and the use of a cosolvent, certain reaction promoters, or a combination thereof.

Abstract: Image display system with storage of data of images to be displayed. Image display systems are known which can at the same time display an image of a first source (MP) and an image of a second source (RP), with the image of the second source (RP) being reduced in its spatial dimensions. In order to permit a simultaneous image display, the two images are separately stored and processed. According to the invention, the two images are stored in a single memory (4). Prior to the storage a processing of the image of the second source is carried out and this image is stored on a consecutive-line basis in the line scan gaps of the image of the first source in the common main memory. The line scan gaps of the image of the first source are utilised for storage. During the period of the line scan gaps, a) that line of the second source which is to be stored is split up into two parts or b) the subsequent line of the first source is delayed (21). The invention is employed in image display systems. <IMAGE>
