Patent DE-4320017-A1 (DE)
Inventor: NIETHAMMER BERND
IPC: F16K31/08
Filed: 1993-06-17
Abstract: A switching valve has a spool or plunger 3 slidable in a valve housing, for controlling the flow between high pressure and low pressure ports 27, 24 and optionally other ports 33. The plunger shuttles between end positions defined by stops 13, 14 which may be adjustable. The plunger is moved by fluid pressure, mechanically, or in any other way. A magnet 5 is provided, for example on the plunger, for holding the plunger firmly in one of its end positions by cooperating with a magnetisable plate 7. This renders the valve effectively bi-stable and eliminates the need for restoring springs. A spring may also be used at either end of the spool and in one end position the magnetic attraction force may be assisted by a magnetic repelling force. <IMAGE>

Title: Process and apparatus for welding plastics profiles
Inventor: HILL WOLFGANG
IPC: B29C65/20
Filed: 1993-08-24
Abstract: The invention relates to a process for welding plastics profiles, in particular for forming window frames, in which the strained plastics profiles are pressed initially for a short time with their bonding surfaces against a hot plate welding tool which can be moved in and can be heated by a heating circuit which can be closed in dependence on at least one temperature sensor and are pressed against each other and thereby welded to each other immediately after achieving a predetermined initial melting of the bonding surfaces. In order to rule out cooling of the middle area of the hot plate welding tool during the initial melting operation of the bonding surfaces of the plastics profiles to be welded to each other, and consequently to ensure satisfactory quality and high strength of the weld, a short time before or at the beginning of the initial melting of the bonding surfaces of the plastics profiles the temperature-controlled heating circuit is interrupted for a short time and the hot plate welding tool is heated uninterruptedly by means of a second heating circuit during this time. <IMAGE>

Title: Magnetic tape recording and playback device
Inventor: MORIMOTO TAKAO
IPC: G11B15/18
Filed: 1994-04-20
Abstract: In the case of a magnetic tape recording and playback device, a resilient body is in engagement with a head base. At the time of recording and playback of a tape, the head base is pressurised and fixed when the resilient body is acted upon directly by the pressure of a lever, and at the time at which the head is drawn back the head base is driven directly by the lever, so that an engaging part of a main base is in engagement with a pressure-applying part, and the head base is pressed on and fixed. In this way, a force exerted on the resilient body at the time of the movement of the head base is reduced. It is possible to reduce the required head-base driving force at the time of movement of the head base.
