Patent DE-3842633-A1 (DE)
Inventor: MEYER ERNST-AUGUST ING GRAD
IPC: F16K31/42
Filed: 1988-12-17
Abstract: A servo-operated multiway valve is disclosed which can be optionally used as both a pressurization valve and a ventilation valve for use with a fluid consuming device. The valve utilizes a valve body to allow fluid communication alternatively between two inlet/vent fluid chambers and an outlet fluid chamber disposed along a central bore, in which the valve body is located. The device utilizes a servo to displace the valve body of the multiway valve. Fluid may be introduced to the valve through either of two inlet/vent chambers, to alternatively allow fluid to flow to the outlet chamber in the resting or the activated mode of the servo. The servo is in fludi communication with the selected inlet chamber at all times, and does not communicate with the selected vent chamber. This is achieved through the use of dual passages, connecting each of the inlet/vent chambers to the servo. Fluid flows from the appropriate inlet chamber to the servo, through the associated passage. A check valve in each passage prevents backflow between the servo and the associated chamber, when that chamber is functioning as a vent.

Inventor: BECK ERNST ING GRAD
IPC: B23D65/00
Filed: 1988-12-23
Abstract: Formed around a tooth (10) is a shaped cavity (26) which is closed at tooth face (12) and tooth flanks (14) and forms a cap (28) in the molten material (20) due to its surface tension. Before solidification of the material, the said cap is flattened to approximate it to the intended shape of the tooth back (14) by applying a pressure progressively on the cap (28) in the direction of the tooth tip (18). When the hard material is melted using a gas or plasma jet, the latter can, after melting the hard material, be moved over the cap (28) in the direction of the tooth tip (18).

Title: Rain-protection rail for the door thresholds of balcony doors
Inventor: SCHENK HERBERT
IPC: E06B7/26
Filed: 1989-03-07
Abstract: Rain-protection rail for the door thresholds of balcony doors, comprising an aluminium profile body which, as basic profile, covers the door threshold and extends laterally beyond the door frame. Up until now, rain-protection rails of this type have had to be notched in the region of the door frame in order also to cover the door threshold in this region. This notching, that is to say a cutting-to-size of the profile metal sheet for the purpose of cutting out the door-frame cross-section, is work-intensive and thus costly. Furthermore, it has not been possible with this design, or it has only been possible with a considerably greater degree of outlay, also to protect the door frame against rainwater running down, in the region of the roller-blind rails fitted on the front side of said frame. The invention avoids these disadvantages in that additionally clamped onto the basic profile in the region of the outer door-threshold edge is an angular, additional rail which likewise comprises an aluminium profile and of which one leg is flush with the upper side of the basic-profile metal sheet covering the door threshold and the other leg at least partially covers the front side of the door threshold and can be fastened thereon, and in that the additional rail extends, on both sides, beyond the door frame to beneath the roller-blind rails fitted thereon.

Title: Re-melting surface hardening process esp. for cam shaft or drag lever - has central and border regions heated at different times or using geometrical displacement to minimise surface deformation
Inventor: BARTON GEORG DIPL-ING DR
IPC: C21D1/09
Filed: 1989-05-23
Abstract: Remelting surface hardening process, esp. of drag lever contact surfaces and camshaft (2) contact surfaces, has the border regions (7, 8) of the surfaces and the normal surface regions (3) acted upon by the heat source (4) with a time differential or geometrical displacement so that the two regions are not simultaneously in the fluid state.
