Abstract: In an internal combustion engine, a hydraulic system for varying the timing of at least one camshaft (20) relative to a crankshaft (26), said system comprising: 
   a drive flange (24) adapted to be coupled to the crankshaft for rotation about an axis; 
   a driven flange (22) adapted to be coupled to said at least one camshaft (20) for rotation about said axis; 
   a hydraulic coupling (32) including a first member (34) connected to one (22) of said flanges and a second member(37,38) co-operating with said first member (34) and connected to the other of said flanges (24), said first and second members (34,37,38) together defining a fluid chamber (42,43) adapted to be continuously filled with fluid, the relative displacement of said chamber varying as the drive and driven flanges (24,22) rotate about said axis relative to one another, said fluid within said chamber (42,43) having pressures which cyclically vary as the camshaft (20) rotates; and 
   valve means (44) for regulating the flow of fluid to said chamber (42,43) in response to a control signal to cause the drive and driven flanges (24,22) to rotate relative to one another in a direction selected without any external power utilising the cyclically varying fluid pressures within the chamber (42,43).

Abstract: A crystal oscillator circuit has a sleep mode of operation that reduces power consumption while maintaining oscillation to provide for a fast transition to a normal mode of operation. The oscillator comprises current mirror coupled current sources (30,32,34). The first (30) and second (32) provide current to a first (16) and a second (22) amplifier. The third current source (34) is in normal mode coupled to a normal mode biasing current source (36) and in sleep mode to a bleeder resistor(40). In normal mode the amplifier (16,22) receives a large, normal mode current determined by the normal mode biasing current source (36). In the sleep mode a very small current sufficient for manforming the oscillation of the crystal oscillator is applied to the first amplifier (16). This current is determined by the bleeder resitor (40). The second amplifier (22) is shutdown because it is coupled to ground.

Abstract: A network video server apparatus and method for transferring video image data across a computer network serving multiple clients. The network server apparatus comprises two parts, a server and a client. The server is run on a computer system containing a video digitizer hardware. Running the server on this computer system makes it possible to distribute video images across an existing network linking several client computer systems. The client provides the user with a means of viewing the images generated by the server through the network, controlling the size and type of image to be sent by the server, controlling the underlying video digitizer hardware, and collecting statistics about the server/client performance. The client software is designed to appear to the users as if they were operating the client software locally. The server and client communicate with each other over two channels: one for control information and another for video data. Data transfer from a server to a client is asynchronous such that the server need not wait for a client to complete its receipt before servicing the next client.

Abstract: La présente invention propose un procédé pour la fabrication de bandes de non-tissés (10) dans lequel la matière fibreuse contenue en désordre (3) dans un bac (2) en est tirée par une paire de cylindres d'alimentation sur une fonture (6). Des peignes (7, i) de la fonture (6) entraînent la matière fibreuse (3) de manière à produire une bande de non-tissés (10). La fonture (6) transfère cette bande (10) sur un cylindre ouvreur à dents (8), ce qui améliore encore la désintégration de la bande (10). Cette formation d'une bande de non-tissés ménage les fibres plus que lors des procédés connus jusqu'ici et ne modifie notamment la répartition des longueurs de fibre que d'une manière insignifiante.

Abstract: Moulded-part carriages (22, 24) which belong together in pairs and which each bear a moulded part (12, 14) can be displaced in relation to one another along a moulded-part guide. On a clamping frame (50), which is separate from the moulded-part carriages (22, 24), clamping devices (82, 84) are assigned for clamping the moulded parts (12, 14) together. The clamping frame (50) can be moved to and fro between an operating position, in which it surrounds three pairs of moulded parts (12, 14), and a rest position, in which it releases these moulded parts. Three additional pairs of moulded parts (12, 14) are arranged on additional moulded-part carriages (22, 24) outside the clamping frame (50) as long as the latter surrounds the first-mentioned moulded parts (12, 14). The clamping frame (50) is, in its rest position, in which it is pivoted away upwards from the first-mentioned moulded parts (12, 14), displaceable parallel to the moulded-part guide (30) and subsequently pivotable into a new operating position, in which it surrounds the additional moulded parts (12, 14), and these are then clamped together by the clamping devices (82, 84). <IMAGE>

Abstract: The invention relates to a method for manufacturing a grinding tool, preferably for the profile grinding of gear wheels. It comprises a metallic basic body (2) which, in terms of its radial-section profile, corresponds to the finished form of the tool and is coated with a single layer of abrasive crystals (3), preferably CBN or diamond, by means of a galvanic or a chemical process. According to the invention, the basic body is coated with a mixture of abrasive crystals (3) and crystals or grains (4, 6) which are not capable of cutting and are of the same dimension. Before using the tool for the first time, the crystals or grains which are not capable of cutting are released, or at least set back, by means of a mechanical, chemical or electrochemical process. Preferably, 30-70 % by volume of crystals which are not capable of cutting are incorporated in the crystal mixture in the form of glass crystals. By means of the method according to the invention, the grinding tool acquires larger saving chambers and this results in a higher output capacity. <IMAGE>

Abstract: An article handling system  (10)  which essentially consists of a spiral slipsheet  (16) . To load articles, the slipsheet is rotated and deflected upward so that incoming articles are inserted into the space thus created between the coils of the spiral. As the articles spiral upward on the slipsheet, the upper articles are supported by the articles which have been fed in below them. To unload articles, the entire assembly is rotated 180 degrees and the rotation of the slipsheet reversed to reverse the above process.
