Patent DE-3810180-A1 (DE)
Title: Broadcast receiver, particularly vehicle receiver
Inventor: DUCKECK RALF
IPC: G08G1/09
Filed: 1988-03-25
Abstract: In vehicle receivers having a decoder for decoding traffic messages received digitally coded, storage devices are provided which contain route-specific features. This makes it possible to display or reproduce standardised texts by radiating memory addresses alone. A limitation of route-specific features is desirable in view of the multiplicity of continuously radiated traffic information items which would occur in the case of supraregional information. Apart from routing names which relate to the travelling route currently relevant, it can also be of interest to obtain information on traffic events in other areas. It is therefore proposed to store the route-specific features of limited geographic regions, particularly place names, provided with a common identification. Inputting the identification then makes it possible to select traffic messages relating only to this or also to this geographic region. <IMAGE>

Abstract: PCT No. PCT/EP90/00786 Sec. 371 Date Dec. 27, 1990 Sec. 102(e) Date Dec. 27, 1990 PCT Filed May 16, 1990 PCT Pub. No. WO90/14677 PCT Pub. Date Nov. 29, 1990.Safety bumpers provide flexible strips for making contact inside a hollow space in a foamed body. It is suggested to carry out the making of contact by way of a closed switching strip which is mounted in a hollow space bordered by a frame preferably designed as a U-profile. An elastic pressure strip having webs extending transversely with respect to the switching strip is assigned to this switching strip. As a result, making of contact is ensured in the case of an arrangement which is not susceptible to pollution and humidity influences and which also permits a pre-assembling.

Title: Sampling flowing medium by computer controlled intermittent extn. - pumped into collector vessel in detached housing
Inventor: RENNER HUBERT
IPC: G01N1/00
Filed: 1989-08-21
Abstract: A fully representative average sample of the liq/gas medium flowing continuously in a conduit over any desired period, eg. in the course of mfr., is produced by diverting a succession of samples, taken at programmed intervals for programmed periods, into a collector vessel. Through interconnecting flexible hoses, the samples are transferred by a pump (7) controlled by a keyboard (14) within the lidded housing for collector, pump etc.  Pump speed collector capacity and total flow duration are among factors processed by the electronic control system.  Sampling from the conduit is by a needle with pointed sloping aperture pushed through flexible septum inside a screwed extractor fitting.  Increasing pressure from air or gas above liq. entering the collector is countered by discharge through a needle pipe and a filter which also prevents ingress of bacteria, dust etc. USE/ADVANTAGE - Suitable for beer, milk lemonade etc.  Sample size is directly proportioned to and repressenative of total flow over a specified time.

Title: Polyurethane integral foam moulded articles prodn. - by reacting poly:ol component with isocyanate component e.g. using RIM and irradiating the moulding with electrical energy, e.g. UHF
Inventor: LEITNER HORST
IPC: B29C35/08
Filed: 1990-06-22
Abstract: Moulded articles of polyurethane integral foam, esp. body parts for the automobile industry, are made by (1) preparing the polyol component (A-component).

Filed: 1990-08-03
Abstract: The fluid actuator has a longitudinally slotted cylinder (1) in which a piston (3) having a connection means (12) reaching through the slot (10) in the cylinder (1) is axially displaceable. The connection means (12) is firmly connected to a driving feature (13) which can be moved in front of the slot (10) on the outside of the cylinder. The driving feature (13) is overlapped by a power output member (14) which is guided in longitudinally displaceable fashion directly or indirectly on the cylinder (1) separately from the piston (3). To couple the driving feature (13) to the power output member (14), the driving feature (13) has a transverse groove (20) on the side facing away from the slot, in which groove there is a feather key (22) crossing the slot (10) at right angles. The feather key (22) extends beyond the transverse groove (20) on both sides and engages with its end portions in corresponding recesses (21) of the power output member (14). The coupling device between the driving feature (13) and the power output member (14), consisting of the feather key (22), the transverse groove (20) and the recesses (21) can be designed to be parallel to the cylinder axis (9) and virtually without play in the pourer transmission direction but allows sufficient relative movements and rotations between the driving feature (13) and the power output member (14) for practical use, such that jamming is reliably avoided. <IMAGE>
