Patent DE-3821722-A1 (DE)
Title: Grating or mat
Inventor: ARENS ERICH
IPC: A47L23/24
Filed: 1988-06-28
Abstract: The invention proposes a grating or a mat which can be used, in particular, as a doormat. It is composed of a multiplicity of profile bars or mouldings 1 which are directed with their longitudinal axes parallel to one another, are provided in their longitudinal direction with undercut grooves 5 and are connected to, and spaced apart from, one another by retaining elements 2 which run transversely with respect to said profile bars or mouldings. Insert strips 7 consisting of a deformable material, e.g. of felt, brush material or textile covering, can be pushed or pressed into the undercut grooves 5. In order that worn insert strips 7 can be easily exchanged, even directly at the location of use, strip-shaped filler pieces 12, with pin-like or peg-like protrusions 14 distributed over their length, can be inserted into the undercut regions 13 of the undercut grooves 5. The protrusions project over the delimiting edges of the opening gap 9 into the groove cross-section at a distance above the groove base 16, while the insert strips 7 are of a width which is matched to the width of the opening gap 9. In this arrangement, the pin-like or peg-like protrusions 14 of strip-like filler pieces 12 can, as retaining members, be made to engage in a positively locking manner into the side surfaces of the insert strips 7, to be precise in particular in that, with elastic deformation of adjacent side-surface regions of the insert strips 7, they can be pressed into the latter as latching members. <IMAGE>

Title: Cutter
Inventor: NORBISRATH MAX
IPC: B02C18/24
Filed: 1988-08-20
Abstract: In the case of known cutters, in particular the silencing, mechanical processing and installation frequently prove to be problematic or costly since the cutter-shaft unit and the dish unit of the cutter form a complete machine body or must be connected to each other in a suitable manner. According to the invention it is intended to mount the cutter-shaft unit (12) and the dish unit (25) on an essentially plate-shaped foundation (1) as separately manufactured parts and to connect them to the said foundation (1). The cutter according to the invention can be used particularly advantageously in the case of large processing volumes, high cutter speeds and high capacities and has, incidentally, a high degree of vibration damping and silencing. <IMAGE>
Patent DE-3830356-A1 (DE)
Title: Device for testing the tightness of gas conduits
Inventor: KRAEWER HANS-PETER
IPC: G01M3/28
Filed: 1988-09-07
Abstract: The leakage quantity of a gas conduit is to be determined for testing the tightness of the gas conduit under operational pressure. Up until now it has been customary to set the closed gas conduit under pressure for this purpose and to determine the leakage quantity from the pressure drop occurring and from the volume of the gas conduit. This measurement is, however, very inaccurate. The device according to the invention consists of a pressure pump which can be connected to the conduit to be tested and consists of a pressure cylinder and pressure piston with piston rod and of a pressure indicating device connected to the pressure pump. After setting the operating pressure, the operating pressure of the closed-off gas conduit can be kept constant by means of subsequent displacement of the pressure piston. The amount of the subsequent displacement of the pressure piston yields the leakage quantity of the gas conduit.
Patent DE-3831474-A1 (DE)
Title: Thermally controlled valve
Inventor: FOELLER WERNER DIPL ING
IPC: F16K31/56
Filed: 1988-09-16
Abstract: Due to the opening force of the spring, a relatively high closing force has to be transmitted from the diaphragm member to the closing part in order to close the valve. This gives rise in the diaphragm member to high stresses, which shorten the life of the diaphragm. The new valve is to have a long diaphragm life. The spring is designed as a Belleville spring (14) and supports the diaphragm member (7) over a large area against the internal pressure in the diaphragm capsule (5), during the entire stroke of the said diaphragm member. Thermally controlled valves with a diaphragm capsule for wide ranges of operating pressures. <IMAGE>
Patent DE-3836708-A1 (DE)
Title: Method for controlling the temperature of rooms
Inventor: SCHMIDT HARALD
IPC: F24F5/00
Filed: 1988-10-28
Abstract: In the method, a high shaft is provided, on which a heat exchanger through which water flows is arranged at the upper and lower end. As long as the water is cooler than the room air, a downwardly directed natural convection occurs in the shaft. The cooled air leaves the shaft at the lower end and spreads out in the room to form a coherent layer. To reduce the vertical temperature difference, the floor-covering cooling layer is raised by disturbing air. If the water is warmer than the room air, an upwardly directed natural convection of the air occurs in the shaft. By water-side series connection, simultaneous heating and cooling is prevented.

Abstract: Containers which serve for storing magnetic-tape cassettes are known. In these, the magnetic-tape cassettes are stored on slides which can be pushed together with a magnetic-tape cassette lying thereupon against a spring force into the container housing. To obtain a receiving container for the cassette-storing containers themselves, a container is proposed in which the cassette-storing container rests on a sliding element and, in the removal position, the cassette located therein is brought by a movable receiving part into an angled position by the cover of the cassette-storing container being raised upright.
Patent DE-3842368-A1 (DE)
Inventor: WETZELS RALF
IPC: G02B6/38
Filed: 1988-12-16
Abstract: In a detachable connector for the pair-by-pair coupling of the fibre ends (14) of two optical fibres, two plugs arranged in the opposite direction from one another are used which are connected to one another by a common coupling. To develop a connector which can be handled easily and rapidly and which is distinguished by an accurate alignment of the two fibre ends, it is proposed to provide as holder for cylinder ends (40) a cage (34) which is provided with profiled rods (57) arranged axially parallel to one another in the gap area (44) between the cylinder pins (40). The radial outsides (55) of the cylinder pins (40) protrude between the profiled rods (57) and determine a circumference (52) which, in the coupling case, is constructed to be greater than the clear opening width (53) of the socket (51) belonging to the coupling. The socket is therefore radially extendable by the same amount at the places in contact with the free outsides of the cylinder pins 40 and during this process generates a tensioning force (42) which is directed radially towards the centre point (16) of the circumference (52) of the cylinder pins and therefore centres the fibre ends on the centre axis of the socket (56). <IMAGE>

Title: Simple device for safe and weather-protected baiting of rodents
Inventor: NIEMEYER HANS DR
IPC: A01M25/00
Filed: 1989-02-23
Abstract: A device for safe, weather-protected baiting of rodents is indicated, which consists of a hollow body (1) which is curved in its longitudinal axis and, in the use position, is placed on the ground (6) in such a manner that the two openings (2), as slipping-in hole for the rodents, touch the ground (6) with their lower edge and the centre of the hollow body (1) has the maximum possible spacing from the ground (6). By means of this, rain, snow or melt water is prevented from penetrating the region of the bait container (3) arranged in the highest section of the curve and the urine of the rodents is prevented from collecting on the running surface (1') of these animals. The bait container (3) consists in the preferred embodiment of an upwardly open basket made of wire mesh, through which the rodents can gnaw the bait pieces from below; its lower surface is as wide as the clear width of the hollow body (1) and just as curved so that the bait container (3) can be pushed into the hollow body (1) without a special holding device and also requires no special closure as the hollow-body wall serves as such. Sliding out or pulling out of the bait container (3), e.g. by children, is prevented by the screw (4) with which the bait container (3) can be locked. The arrangement of the bait container (3) above the running surface (1') guarantees that the bait pieces do not [lacuna] with the excrement of the rodents or with ...

Title: Light, in particular rear light of a motor vehicle
Inventor: ZWICK HUBERT
IPC: F21S8/10
Filed: 1989-02-24
Abstract: The lights which are constructed as rear lights for motor vehicles serve as brake light, rear light, fog light and as reversing light and flasher indicator light. For these lights it is prescribed that the rear light is white, the flasher indicator light yellow and the brake light, rear light and fog light red. In the case of the rear lights of motor vehicles with grey tinted light covers, colour filters which correspond to the respective light functions are arranged behind the said covers. In order to avoid additional colour-producing components being required to produce the functional colours, the cover areas have coloured cover elements which are of grid-shaped arrangement, correspond to the colour of the brake light, rear light, fog light and reversing light components and are arranged distributed within each cover area. At least one beam deflecting component which deflects the light beams to identically coloured cover elements within the respective cover area is arranged between the light cover and the light source. The light cover which consists of the coloured cover elements is of homogeneous construction in terms of colour. Additional colour filters and/or other devices which produce the functional colours are superfluous so that the light can be installed simply and manufactured cost-effectively.

Title: Electrical energy from solar energy - via methane deforming process and fuel cell
Inventor: CZIMCZIK ARNO DIPL PHYS
IPC: H01M8/0612
Filed: 1989-10-05
Abstract: Solar energy is converted continuously in high-temp. heat of a fluid which is stored and transformed electrical energy. The reaction partner of a methanem reforming process is heated to produce a gas which is stored with a high energy density and is directed to a fuel cell for electrical energy generation. Pref. solar energy(SE) received by a radiation collector(1) is transferred to a gas (G), e.g. air or CO2 which passes through a pipe(2) to a reformer(3) with cracking tubes(4) and back via a cooler(6) and compressor(7). The cracking tubes receive CH4 and H2O from a heat exchanger in which the gas produced(PG), which is high in H2, is cooled. A shift converter(9) raises the H2 share and a pressure vessel(10) eluates further CO2 shares. The H is passed to a fuel cell(11) together with air or O2. ADVANTAGE - This minimises the vol. required for storage and achieves a better efficiency.
