Patent DE-3808438-A1 (DE)
Title: Device for receiving and delivering liquid and pasty substances
Inventor: GALIA KARL
IPC: B65D83/14
Filed: 1988-03-14
Abstract: A dual-chamber container contains, inter alia, a rigid outer container and a flexible inner container. In their upper regions, they are connected to one another in a gas-tight manner. According to the invention, they are welded or bonded to one another along at least one seam in the upper third of the outer container. The welding process used is preferably roller welding and welding with a laser beam. The welding or bonding allows the two containers to be varnished subsequently in a conventional manner, the container neck to be constricted, and the container edges to be beaded with one another and with a lid or dome forming a rolled edge.
Patent DE-3814900-A1 (DE)
Inventor: BUCK WALTER DR
IPC: H04B7/02
Filed: 1988-05-03
Abstract: In the diversity reception process and antenna system for mobile reception, in particular for receiving radio programmes in cars, signal samples are taken from individual antenna or linear-combination signals, then sequentially modulated with an auxiliary modulation signal, and a summation signal based on antenna or linear-combination signals is applied to them. After said summation signals incorporating sample signals have been demodulated and their value and phase relative to the corresponding summation signal have been established, they can be used to set the phase angle rotation links to obtain optimum addition of power in a summing circuit, and in particular also to switch off completely one antenna or linear-combination signal from the global antenna system in order to avoid power reflections on inputs with limited signal level. Meanwhile all antenna signals are continuously controlled through the sample signals taken.

IPC: G01S3/38
Filed: 1988-07-28
Abstract: For a direction-finding arrangement having directional antennas with differently aligned main beam directions in order to determine the incidence angle of a signal from the amplitudes in the individual direction-finding channels, a circuit concept is specified which, in the case of 2<N> directional antennas with any desired angular zone coverage, enables rapid direction-finding angle determination, and thus also the determination of the incidence direction of very brief signals, by means of comparators and changeover switches.
Patent DE-3832137-A1 (DE)
Title: Adjustment of the "inlet closes" valve timing during the operation of axial flow rotary engines
IPC: F01B3/10
Filed: 1988-09-22
Abstract: Adjustment of the "inlet closes" (ES) valve timing influences the consumption and performance of 4-stroke engines more than all other valve timings. In axial flow rotary engines, in which the rotating cylinders (4) are fixed to the engine shaft (3), a continuous adjustment of the valve timing (Es) can be achieved as shown in Figs. 1, 2 and 3: In addition to the spark plug (10) and the exhaust port (11), the cylinder cover (2), fixed to the engine housing (1), also contains the inlet port (8), past which the cylinders (4) with the pistons (5) rotate. From the inlet opening (9) to the end of the inlet port (8), a plate (7) precurved in an S shape is fixed in the latter so that it is spring-loaded against a pin (6) and the "inlet closes" (Es) control edge lies at the end of the inlet port (8). If the pin (6) is then pressed downwards by the force (P), the control edge (Es) migrates infinitely variably so far in the direction of the inlet opening (9) that an adjustment facility, sufficient for all operating conditions, is ensured during operation. <IMAGE>

Title: Runner system for feeding molten material into a casting mould
Inventor: BISSINGER FRIDOLIN
IPC: B22D35/04
Filed: 1988-10-21
Abstract: To feed molten material to the cavities provided for its reception in the casting mould, use is made of a runner system (1) which consists of prefabricated round-pipe sections (5 to 8) and prefabricated connecting elements (9 to 12) in the manner of fittings, which can be put together in modular fashion. Owing to the round cross-sectional shape of the runners which is obtained thereby and is favourable in terms of flow and owing to the quantity of foam plastic in the runner system (1), which is reduced by the cavity in the round-pipe sections (5 to 8), which foam plastic must be gasified by the molten material before it reaches the gates (3, 4) and the foam-plastic pattern mould (2), a low-resistance flow of the molten material with a low temperature loss results, so that complex and extensively branched runner systems (1) can be realised. As a result, it is also possible to cast large and complex castings homogeneously, starting from only one inlet (13), and in the case of small castings a multiplicity thereof can be cast using only a single runner system (1). Owing to the efficient prefabrication of the elements of the runner system and the simple push-in connections, the runner system (1) can be constructed in a very short time and adapted to the requirements of the molten-material conveyance in each particular case. By using round-pipe sections (5 to 8) of different diameter and with a suitable shape of the connecting elements (9 to 12), the flow conditions for the molten material can be selectively influenced and ...

Title: Optical picture transmission system
Inventor: KANAMORI IWAO
IPC: A61B1/00
Filed: 1988-11-10
Abstract: An optical picture transmission system is specified for a non-flexible endoscope. The picture transmission system comprises a multiplicity of lens components. A spherical lens surface (3b, 4a, 4a', 3b') in the vicinity of the aperture diaphragm (5) of the optical system serves to correct the spherical aberration. An aspherical lens surface (3a) in the vicinity of the object has regions whose curvature decreases gradually with the distance of the regions from the optical axis when the medium on the entrance side of this surface has a smaller refractive index than the medium on the exit side. An aspherical lens surface (3a) in the vicinity of the refocused picture has regions whose curvature decreases gradually with the distance of the regions from the optical axis when the medium on the entrance side of this surface has a higher refractive index than the medium on the exit side. The optical picture transmission system can effectively correct astigmatism, spherical aberration, and other aberrations. A plurality of optical systems, arranged one behind the other, make it possible to view objects which are remote from the viewer endoscopically. <IMAGE>

Title: Air-supply device for a welding machine for processing films of plastic
Inventor: GRELLER PETER
IPC: B29C65/10
Filed: 1989-04-07
Abstract: The air supply device is intended to make satisfactory welding results possible even under difficult operating conditions. The air supply device has a nozzle and attachment (32) arranged adjustably on the said nozzle, the distance of the attachment from the nozzle (13) and its angular alignment being variable. Depending on the size of the distance, part of the hot air emerging from the nozzle (13) does not flow through the attachment but past the outer side thereof and effects a preheating of the films. The hot-air welding machine serves for joining films of plastic by forming a seam. Fig. 2 of the attached drawing is suggested as the drawing for the abstract. <IMAGE>
