Patent DE-4208613-A1 (DE)
Inventor: SCHUTTER JAN
IPC: G01R31/00
Filed: 1992-03-18
Abstract: This method is carried out with the aid of a test instrument into which test parameters are entered by means of an input unit. A corresponding method is to be specified which operates particularly quickly and accurately. This is achieved by a theoretical triggering characteristic (1) of the respective protective relay being stored in the test instrument. Each test point (4) of the actual triggering characteristic (5) is determined along a search line (3), the starting points of the measurement being an intersection (2) of the search line (3) with the theoretical triggering characteristic (1). The search line (3) intersects the theoretical triggering characteristic (1) at an angle ( alpha ). The angle ( alpha ) is within a range from 60 DEG  to 120 DEG , 90 DEG  being preferred. <IMAGE>

Title: Opening and closing mechanism for blow mould tools - has mould clamping plates with extensions mounted on columns and spindles which have specific type drive for precise linear movements
Inventor: SALVO GONZALEZ AUGUSTO E
IPC: B29C49/56
Filed: 1992-07-13
Abstract: Mechanism for opening and closing moulds in the production of hollow plastic mouldings has two mould clamping plates which are moved linearly to/from each other by spindles driven through a transmission by a reversible motor. The linear movement is produced by a drive system of recirculating ball screw and nut in which the nuts are located in the clamping plates. The mould clamping plates (2,3) have extensions, with the recirculating ball nuts (6) and spindle (5) below the mould tools themselves (1). The spindles (5) acting with the nuts (6) have one left-hand thread (18) and one right-hand thread (19) and are mounted in a channel-section holder (9) which can be moved relative to an extruder for a blow-moulding equipment. The spindles (5) are suitably driven e.g. by chains etc. and gear wheels from a motor. The drives system (4) not only closes/opens the mould (1) but also positions the mould precisely in relation to the extruder. If heavy moulds are used, the assembly is reinforced by columns (11) which provide exact guides and take up most of the load. ADVANTAGE - The layout is greatly simplified. It ensures secure closure and opening. It is suitable for use with high closure and dwell pressures. It is inexpensive, has a light drive and requires little maintenance.

Title: Video cassette recorder with reception aerial and tuner - has input terminal for external video source, e.g. another VCR
Inventor: KIM CHEONG SIK
IPC: H04N5/765
Filed: 1993-02-01
Abstract: The tuner responds to the TV signals received via a selected channel, while an input stage feeds in a lead signal from an external video playback. A control provides a first change-over signal for recording, and a second change-over signal for viewing as required. A first change-over switch selectively supplies an output signal from the tuner and the input stage, as triggered by the first control change-over signal for recording. A signal processor deals with the output signal of the first change-over switch for its recording. A recording head deals with the first signal processor output signal for accommodating the video cassette recorder tape. USE/ADVANTAGE - Selective video recorders, allowing re-recording. Permits viewing while recording from other source, i.e. video input or broadcast.

Title: Headlamp (headlight) for vehicles
Inventor: BERTLING JOHANNES-GERHARD DIPL
IPC: F21V5/00
Filed: 1993-05-08
Abstract: The headlamp has a reflector (10) into which a light source (14) is inserted. The light emitted from the light source (14) is reflected by the reflector (10) as a converging light bundle (16). A diverging lens (concave lens, negative lens) (24) is arranged in that region of the front edge (22) of the reflector (10) which points in the direction (20) of the light outlet. The diverging lens (24) has a plane surface (flat surface) (26) which faces the reflector apex (12) and a concavely curved surface (28) opposite the plane surface. The shape of the reflector (10) and the shape of the concavely curved surface (28) of the diverging lens (24) are defined and matched to each other in such a manner that the light emitted from the light source (14) achieves, after reflection at the reflector (10) and passage through the diverging lens (24), an illumination intensity distribution (illuminance distribution) which meets the legal requirements, without any further optical means being necessary for this purpose. As a result of the diverging lens (24) arranged in the region of the front edge (22) of the reflector, the headlamp has a small overall depth. <IMAGE>
