Title: Two roof members with joint along length
Inventor: WESTHAUS HEINZ
IPC: E04D3/38
Filed: 1991-10-31
Abstract: Surface-textured roof members are joined longitudinally, where each consists of a foam core with two metal skins. Joint is within an upstanding section and has a seal. Beneath, the lower skin on the one member is indented just in front of the joint, where a corresp. lip on the other member fits in. Main part of the thickness of the member here is its foam core. At the joint the two top skins are screwed together where a metal plate overlaps the joint and has inclined edges along its length; one such edge covers a part of the metal skin of one member which is pointing upwards and the other edge similarly covers a part of the skin of the other member. Metal plate is fitted with a bolt which passes vertically through the one member and fixes it to the support structure. Each upward pointing part of a top skin of one member forms a trough; another upward projecting part of the metal skin forms a groove and a part of a cover fits into this. At least 60% of the thickness of the joint is filled with an elastic foam seal where the bottom end fits on to a tongue in the lower skin on one side of the joint. Edge of this tongue projects out into a recess in the other roof member to a deg. depending upon that of compression of the elastic seal. Compensating gap is left between the parts of the members gripped by the cover plate. Elastic seal concerned is pref. e.g. an impregnated soft polyurethane foam.

Title: Wheel assembly for support of planetary gearing - has axially offset spur gears circumferentially overlapping
Inventor: HOFACKER FRIEDRICH
IPC: F16H57/08
Filed: 1991-11-30
Abstract: With two planetary wheels (6, 7) adjoining each other in the circumferential direction of a central axis the tooth width (13) is less than the tooth width of the central wheel. The spur gears (16, 17) are offset from each other both in the directions of the central axis and in the circumferential directions of the central axis with mutual overlapping. The spur gear (16, 17) of the planetary wheel (6, 7) is mounted on a hub part (19) of reduced dia. The hub parts of all the planetary wheels can be the same. USE/ADVANTAGE - Through the larger number of planetary wheels the tooth force distribution on the central wheel is more even and the service life is thereby increased.

Title: Removing pieces of broken bottles in filling machine - using circulating rotor with fittings which do not rotate with it for removal of glass pieces from bottle carrier
Inventor: CLUESSERATH LUDWIG
IPC: B67C3/22
Filed: 1992-02-10
Abstract: On the circulating rotor are several filling positions, each of which comprises a filling element (2) and a bottle carrier (3), which are movable by a lift device relatively to one another in an axial direction parallel to the machine axis. The filling element (2) has an open bell (19) on its underside, which forms a chamber (21) for complete accommodation of the bottle (4). At its lower open end the bell is tightly closable by a closure element formed by the bottle carrier (3). Members which do not rotate with the rotor remove broken pieces of glass from the bottle carrier when a breakage occurs which activates a signal from a measurement probe (30,47) reacting to liq.. Each filling element (2) has a measurement probe. USE/ADVANTAGE - With bottle-filling machines, to remove broken glass pieces when a bottle breakage occurs.

Title: Utilisation of solar energy at the roof of a building - has a rotating housing on roof opening with inclined reflector to direct solar radiation into opening
Inventor: HUEBNER PETER PROF DIPL ING
IPC: F24J2/00
Filed: 1992-02-14
Abstract: A device controls the solar energy incident at the roof opening of a building like a hall or apartment. Projecting upwards from the roof opening is a housing which can rotate around an almost vertical axis. The housing has vertical or slightly inclined transparent walls, whose upper ends all lie in a common plane at an angle of about 15 to 25 degrees to the horizontal. This plane carries a reflecting surface to reflect solar radiation and light through the opening and down into the building. The reflecting surface is preferably convex but may be a diffuse surface.. ADVANTAGE - Prevents hothouse effect in summer and gives maximum use of solar radiation in winter.
Patent DE-4205433-A1 (DE)
Title: Reduction of fuel vapour-air mixture emission during filling of vehicle fuel tank - requires reducing partial pressure of inert gas (air) in tank prior to filling, either by warming fuel or by adding fuel from reserve tank.
Inventor: CURTIUS FRITZ
IPC: B67D7/04
Filed: 1992-02-23
Abstract: As the fuel is driven out of the tank, the more volatile components in the fuel evaporate faster encouraging an increase in the inert partial pressure, eg. air. This can result in saturated air/fuel mixture escaping during filling of the fuel tank. To reduce this effect the partial pressure of the inert gasses in the tank is reduced prior to filling. This is achieved by warming the fuel or by adding fuel, with more volatile components, from the reserve tank. The warming is carried out electrically or by heat exchange from the engine coolant, or from the exhaust gasses. The return fuel flow can be heated. The reserve fuel is pumped into the main tank prior to filling by a simple driver operated control. ADVANTAGE - Less fuel vapour lost during filling, cleaner environment.

Abstract: A road traffic radio receiver has a first memory (16) in which received addresses are allocated to segments (S1 ...S40) of a road network and an output device (30) for the received coded signals in a clearly understandable form. The road traffic radio receiver is equipped with an accessory (42) having a second memory (44) for driving parameters relating to the segments (S1 ...S40) stored in the first memory (16) and addresses for the segments that follow each segment (S1 ...S40). An input device (34) allows at least one destination to be entered, which is allocated to a stored segment (S1 ...S40). A computer (46) determines the best path to reach the destination (ZP) and the segments belonging to the best path determined by the computer (46) can be stored in a third memory (48). By making use of the segments (S1 ...S40) stored in the first memory (16), the accessory device allows the best path to an entered destination determination by the computer (46) to be indicated.

IPC: G11B19/28
Filed: 1993-03-23
Abstract: A magnetic disc drive system has a disc rotation controller having a processor receiving an input from a hall effect sensor generating pulses with a frequency proportional to rotational speed. A separate unit controls a motor to move the arm carrying the head across the disc. This also has a processor and drive circuit. The disc speed is defined in relation to limit values. A detection routine determines if the rotational speed is within a control region between two speeds (w2, w3). A second routine narrows the speed range check to two finer values (w4,w5). The reset signal for the process is generated as a result of the comparison. USE/ADVANTAGE - Accurate control of speed monitoring process.
