IPC: F16K17/04
Filed: 1992-08-17
Abstract: Proposed is a pressure-relief valve for use in lubrication systems, the valve being designed to avoid overtravel, i.e., the occurrence of a surge, on opening and closing.

Patent DE-4238997-A1 (DE)
Inventor: STERZEL HANS-JOSEF DR
IPC: B29C43/02
Filed: 1992-11-19
Abstract: A process for producing polylactide molded bodies is characterised in that an amorphous polylactide semi-finished product or a compact amorphous preform is heated up to a temperature between 60 and 150 DEG C. The preform remains amorphous and is then extruded in a tool which is equally heated up to a temperature between 60 and 150  DEG C. The polylactide thus flows along multiple axes, is oriented and crystallized.

Title: Method and arrangement for inserting a background signal into parts of a foreground signal which are defined by a predetermined keying colour
Inventor: GEHRMANN RAINER
IPC: H04N9/75
Filed: 1993-06-24
Abstract: A method for inserting a background signal (BG) into parts of a foreground signal (FG) which are defined by a predetermined keying colour (KC) is described, in which method a control signal (k) which assumes a first value when the foreground signal (FG) represents a colour within the range of the keying colour (KC) and assumes a second value when the foreground signal (FG) represents a different colour, is derived from the foreground signal (FG), the control signal (k) having a transition range between the two values and a difference, weighted by the control signal (k), between the vector of the background signal (BG) and the vector of a signal (KC) representing the keying colour being added vectorially to the foreground signal (FG), according to the patent (Patent Application P4143180.4) and an arrangement for carrying out this method is described. A further improvement in the picture quality is achieved with little effort by the fact that the background signal (BG), the signal (KC) representing the keying colour and the foreground signal (FG) in each case have a component representing the blue component (Cb) and a component representing the red component (Cr) and a luminance component (Y) and the said signals are combined in matching aforementioned manner with respect to all components. <IMAGE>

Patent DE-4326334-A1 (DE)
Title: Sleeve-shaped gear for a camshaft adjusting system
Inventor: HEILER JOSEF
IPC: F01L1/344
Filed: 1993-08-05
Abstract: A sleeve-shaped gear is connected by its external toothing to a camshaft and by its internal toothing to a driveshaft for the camshaft. The camshaft can be adjusted in relation to the driveshaft by longitudinal displacement of the sleeve-shaped gear, since at least one of the gear tooth systems is designed as helical toothing. In order to ensure zero backlash despite a relatively simple gear tooth system and to prevent rattling noise, the gear wall has at least one slot running in an axial direction, at the side of which the wall sections are slightly curved in opposing radial directions. Pairs of slots can also be provided, however, the intervening wall sections of which have a slight permanent deformation. In this way the sleeve-shaped gear is virtually braced with the shafts connected thereto.

Title: Semiconductor laser, in particular for use in a laser pointer or a laser-diode module
Inventor: BLAU FRANK W DIPL ING
IPC: H01S5/068
Filed: 1993-08-16
Abstract: In the case of a continuous laser, the emitted power should never exceed a predetermined limit value, because an undesired increase in the laser power, which is a serious danger to human health, can otherwise occur. The novel semiconductor laser is intended, using the fewest electrical or electronic components possible, to prevent the emitted laser power from increasing above a predetermined maximum value more reliably than to date, even if an individual fault occurs in the electronic circuit used for operating the laser. A monitor diode (22; 54) which receives stray light coming from the laser diode (11; 51) and is not involved in functional operation, causes, as part of a redundant protective circuit, switching off or at least reduction of the emitted laser power. The semiconductor laser has a redundant protective circuit which makes do with only a few components and operates very reliably. Undesired and possibly dangerous increases in power can thereby be avoided reliably. <IMAGE>

Patent DE-4332888-A1 (DE)
Inventor: KAESCH DIETMAR DIPL ING
IPC: H02H3/04
Filed: 1993-09-22
Abstract: The tracks of d.c. railways (rail earth) used to conduct the current must be electrically insulated from earth potential. At places where the potential difference between the rail earth and earth potential can reach unacceptable levels, voltage flashover fuses are fitted for protection against dangerous body currents. The condition of these fuses must be continuously monitored so that those which have blown may be replaced immediately. This is at present done by regular track patrols. According to the invention, the potential difference between the rail earth (3) and the earth potential (4) is detected by a reporting device (5) and the condition with the appropriate address is transmitted to an evaluation device and stored therein. If a fuse (2) has blown, the reporting device (5) sends an error message to the evaluation device so that the fuse (2) concerned can be properly replaced. The ease of fitting of the reporting device (5) and the use of radio transmission facilities make it possible to apply the system of the invention directly to existing fuses (2), thus permitting the economical and permanent monitoring of the condition of the fuses (2).
