Patent DE-3833646-A1 (DE)
Title: Storage container for liquids
IPC: B65D88/02
Filed: 1988-10-04
Abstract: A storage container made of thermoplastic for storing liquids is usually made up of a plurality of container elements for reasons of stability, which container elements are connected integrally by means of a connecting channel. The design must be such that, in particular, simple production and a space-saving arrangement of the finished storage container are possible. According to the invention, the connecting channel (3) is connected in each case to mutually facing side walls (4, 5) of the container elements (1, 2) and is designed in such a way that it is variable in length in its longitudinal direction. The storage container according to the invention is suitable for storing liquids of all types, in particular heating oil. <IMAGE>

Title: Device for hand-actuated spraying of a liquid
Inventor: KROSCHEL SIEGFRIED
IPC: B05B11/00
Filed: 1988-10-25
Abstract: To simplify a manual spraying device 1, for example for spray bottles, an overpressure valve 30 is described, which has a valve slide 31 guided in a second hollow plunger 20. The valve slide 21 and/or the top section 22 of the second hollow plunger 20 are provided with elastic fingers 33 and 23 respectively which are deflected radially by the upward displacement of the valve slide in the case of overpressure in the pump chamber 15. A returning force is exerted on the valve slide 31 via sliding surfaces on the fingers (Figure 1b). <IMAGE>

Title: Fuel tank with preheating device, especially for motor vehicles
Inventor: FISCHER KLAUS-UDO
IPC: B60K15/077
Filed: 1988-11-15
Abstract: The invention relates to motor vehicle engineering. The subject matter of the application are preferably fuel tanks for diesel fuel, with intake pipe and return line. The essential characteristics of the invention lie in the fact that the base of the fuel tank is drawn inwards in the form of a conical overflow and that above this a pot-shaped mixing chamber is centrally arranged, which is connected to the intake pipe. The mixing chamber has an exposed edge which is joined to the base of the fuel tank at a distance therefrom, so that an annular distributing chamber is produced, which is provided with passages. Under the overflow a collecting chamber is situated below the base of the fuel tank, to which overflow openings arranged next to the mixing chamber lead. Warmed fuel is led through the return line into the distributing chamber and, distributed over the circumference, flows into the mixing chamber. From the collecting chamber cold fuel passes through the open overflow into the mixing chamber and mixes promptly and thoroughly with the warm fuel, so that a fuel mixture is produced which even at low temperatures guarantees normal engine operation due to the good induction properties. <IMAGE>

Patent DE-3844405-A1 (DE)
Title: Valve arrangement for a hydraulic system
Inventor: NIKOLAUS HEINRICH PROF DR ING
IPC: F15B11/16
Filed: 1988-12-30
Abstract: In a valve arrangement for controlling a plurality of hydraulic consumers, to be actuated simultaneously, independently of load, a pressure balance is allocated to each consumer. The pressure balance can be adjusted in the opening direction by the pressure downstream of the allocated measuring choke and a spring and in the closing direction by the maximum respective load pressure. The load pressure of the load-carrying consumer is fed via a stop valve downstream of the directional control valve into the signal line. The valve arrangement permits many uses, preferably also in combination with a directional control valve with which the direction of flow through the pressure balance can be reversed, so that one pressure balance is sufficient for one double-acting consumer. In addition, the pressure medium fed into the signal line is delivered by the pump and not by the consumer so that stalling is avoided when starting a consumer.

Title: Coin-operated entertainment machine with light-strips in the front region of the longitudinal sides
IPC: G07F9/10
Filed: 1989-01-25
Abstract: Coin-operated entertainment machines having strip-shaped light-strip attachments on the front side are known. In the new design of the light effects for entertainment machines, these are to bring about a decorative effect and achieve increased attentiveness, and at the same time the user is not to be disturbed or distracted from the game by the light effects while he is playing. For this purpose, a hood with a colour roller which can be illuminated transluscently is provided on the top side of the entertainment machine. Furthermore, the light-strip attachments on the front side have light sources surrounded by colour rollers: these light sources are switched off at the start of play.
Patent DE-3905833-A1 (DE)
Title: Method of protecting security zones
Inventor: BROSOW JOERGEN
IPC: G08B15/02
Filed: 1989-02-24
Abstract: The method serves for protecting security zones against uncontrolled access by unauthorised persons. In order to be able also to detect such persons some time still after passing the security zone limit, marking means, namely means which appear optically and/or smell means which, for at least a certain time, remain clinging to the persons coming into contact with them, are uniformly distributed along the limit of the respective security zone to be protected. It is practically exclusively smell means which can be discovered by chemical detectors or by trained animals, preferably trackhounds, but which are preferably practically not noticeable by the human nose which are used, and, as optically appearing means, colour particles or fluorescent material. These marking means, mixed in foam, are distributed along the security zone limit by spreading a foam layer of a width which excludes a surmounting, e.g. by contactless jumping over, by an unauthorised person.

Title: Ablation control using laser beam - uses second laser to generate beam of greater wave length then ablation laser to analyse region at working position
Inventor: DRESSEL MARTIN DR
IPC: A61B18/20
Filed: 1990-02-15
Abstract: The apparatus for controlled ablation of material using laser radiation comprises two lasers (14, 16) the first (14) generating a beam impulse with a wave length in a region suitable for the ablation, e.g. in the ultraviolet spectral region, while the second laser (16) generates a beam with a different, specifically greater wavelength. The beams are transmitted to the required working position via a light conductor (12). The beam from the second laser is used for analysing a region (20) at the working position. The second laser operates via a dichroic mirror (18). A radiation analysing unit (22) e.g. a spectrometer, analyses the material specific radiation from the region (20). A control unit has an adjustable delay unit (28) to retard the release of the pulse of the second laser (16) relative to the pulse of the first laser (14). The first laser is controlled in relation to the output signal of the spectrum analyser. The light conductor system uses fibre-optics or a series of mirrors.
