Patent DE-3211704-A1 (DE)
Title: System and device of a bottom bracket ballbearing lock with function blocking and double antitheft protection
Inventor: BERKHAN GUENTER
IPC: B62H5/10
Filed: 1982-03-30
Abstract: With the disclosed method it is to be ensured that a relatively long pipe network for heated up or warmed up fluids which is connected downstream of the measuring device does not cool down during relatively long rest periods. This can only be achieved if the line lengths connected downstream of the measuring device are also involved in circulation. In conventional water meters, the circulation throughflow is also measured as consumption so that this method can only be used when a second water meter is used in the circulation line so that the differential consumption is then counted as consumption. Unfortunately, this method has the disadvantage that in the case of unfavourable tolerance measurement incorrect values are obtained which have proven unacceptable in practice. The disclosed method is intended to eliminate these losses, this being achieved in that, as a result of the special design of the measuring chamber, in each case the preliminary flow and feedback are directed in parallel into the measuring chamber, specifically in the same flow direction so that when circulation throughflow occurs a pressure compensation is achieved which brings the measuring wheel to a standstill. The pressure difference does not change in favour of the first runnings until a downstream tapping valve opens so that the impeller carries out a precise measurement. The application comprises two embodiments, specifically on the one hand an embodiment with a dividing web in the measuring chamber and on the other hand an embodiment as a separate measuring chamber with the volume flow being diverted by means of corresponding non-return valves into the actual measuring chamber and being removed from the downstream tapping valves. Both versions are provided with a control device which serves to compensate the pressure loss in the pipe network connected downstream of the measuring device.

Title: Housing for electrical information technology
Inventor: EIGLMAIER HERMANN
IPC: H05K7/14
Filed: 1982-03-30
Abstract: A housing (1) with push-in plug-in assemblies (2, 3) for electrical information technology is specified which is intended to be screened below and to the exterior in a very simple manner. The rear wall (10) supporting the plug-in elements (12) consists of a double-coated multilayer printed-circuit board, and the drawers consist of U-shaped sheet-metal parts (3) which have beads (4) on their edges for holding the circuit boards (3), and at the same time are used as guides, and outwardly bent lugs (5), by means of which they make precise contact with the housing (1). The cover (8) on the front side can be plugged on. This results in advantageously simple mutual screening of the assemblies. <IMAGE>
Patent DE-3212309-A1 (DE)
Title: Transfer-printing device
Inventor: IZUHARA HIROSHI
IPC: B41F16/00
Filed: 1982-04-02
Abstract: What is described is a transfer-printing device, by which a convex surface of an article can be printed. For this, a shaft which can be rotated through identical angles of rotation is provided in the transfer-printing device. Fastened to the shaft is a holding block, on which a plurality of pressure pads are provided in turn on its circumference. The pressure pads are brought successively into a transfer-printing position. At the same time, they are heated in a heating mandrel, so that the surface of the respective pressure pad assumes the temperature necessary for the transfer printing. During the transfer printing, the respective pressure pad is sufficiently deformed elastically, without warping or creases forming thereby. Very good transfer printing onto the convex surface of the respective article is consequently achieved in a simple way, a transfer-printing film being used.

Patent DE-3304512-A1 (DE)
Title: Device for welding plastics profiles
Inventor: HOLLINGER PAUL
IPC: B29C65/20
Filed: 1983-02-10
Abstract: After the welding of two or more plastics profiles on a device for welding, the produced frame part must be removed from the device. In known devices an operating person must lift the finished frame part manually over the stops after welding. Depending on the element size, this is very elaborate and laborious. Since the welded frame parts have not yet reached an adequate strength immediately after completion of the welding, displacement and stress cracks often occur with inexpert lifting over stops. In order to overcome the disadvantages, the invention proposes that a device (1) for welding plastics profiles (6, 7) to form at least one frame part (17) for windows, doors or the like, with support surfaces (3) for the profiles (6, 7) be designed in such a manner that a lifting device (14, 16, 34, 34', 46) which automatically raises the welded frame parts (6, 7, 17) after withdrawal of clamping units (22) and which lifts the frame parts (6, 7, 17) over the support surface (3) for removal is provided. <IMAGE>

Abstract: In a switched-mode power supply according to the main application, the changeover between the standby mode and the normal mode takes place from the secondary side via an optocoupler (23) to the primary side. In the case of the present invention, the changeover takes place by isolating the foot-point (k) of the voltage divider (42) for the control voltage (Ur) which is supplied to the optocoupler (23). At the same time, the switch (54) is operated, which switches the first operating voltage (U1), with its reduced value, on as the operating voltage for the remote-control receiver (18). <IMAGE>

Title: Gas-discharge display device having a post-deflection acceleration space, and a method for its production
Inventor: LITTWIN BURKHARD DIPL PHYS
IPC: H01J17/49
Filed: 1983-08-11
Abstract: A gas-discharge display device having a post-deflection acceleration space, and a method for its production. In a picture screen, in which electrons are drawn from a plasma, are accelerated after deflection to a plurality of kV and are finally guided onto a fluorescent screen, the maintaining voltage increases with increasing operating time. In order to prevent this disturbing effect it is proposed to coat the post-deflection acceleration cathode (14) with a graphite layer (22). The proposal is based on the finding that this pressure loss occurs because gas ions are produced on the post-deflection acceleration path and are implanted in the post-deflection acceleration cathode (14). The graphite layer (22) causes the voltage increase to be delayed and to stop at a lower level. A graphite sludge, which is provided with a bonding agent, is preferably sprayed on to produce said graphite layer. Main field of application: flat picture screens, especially for data VDUs and television sets. <IMAGE>
