Patent DE-4337623-A1 (DE)
Title: Process and apparatus for dewatering and deoiling oil sludges
Inventor: HASELHORST MANFRED DIPL CHEM D
IPC: A62D3/00
Filed: 1993-11-04
Abstract: The object underlying the invention is to create a process and an apparatus of the generic type mentioned at the outset with which, using a relatively small amount of equipment resources, oil and water can be economically separated from the residual product then remaining in such a manner that the latter can be landfilled or is reusable, the water can be discharged to the biological system and the oil recovered is reusable. This object is achieved according to the invention by hot flue gases from a burner (4) being passed into the oil sludges introduced into a screenlike dry vessel (2), by release of the free enthalpy of the flue gases most of the water contained in the oil sludges being expelled, together with the oil constituents boiling at the relevant flue gas temperatures, condensed in a condenser (7), this water-oil condensate being passed into a coalescer (14, 16), the water being separated there from the oil and then the end product, before it is landfilled, being subjected to afterburning of the residual oil constituents contained therein. <IMAGE>

Title: Disc (record, disk) player
Inventor: SUZUKI SHOJI
IPC: G11B17/26
Filed: 1994-03-10
Abstract: A disc player or CD player is disclosed, in which a clamping element (15) is raised into a position (A) before a drawer (Tx) is drawn out of a magazine (M); once the drawer (Tx) moves into the space between a clamping chassis (11) and a drive unit chassis (12), the clamping element (15) is lowered into a position (B) and faces, at a short distance, a disc (D) located on the drawer (Tx). In this arrangement, the disc (D) is prevented from moving out of the recessed retaining region (72) of the moving drawer (Tx). When the drawer (Tx) has completed its movement and has moved out of the magazine (M), the clamping element (15) is lowered further, with the result that the disc (D) is firmly held between the disc turntable (13) and the clamping element (15). The result of this is that the disc (D) is prevented from moving away from the drawer (Tx) while the drawer is moving with the disc located thereon to a disc drive unit. <IMAGE>
Patent DE-4408502-A1 (DE)
Inventor: WILMS ELMAR DR
IPC: C11D3/20
Filed: 1994-03-14
Abstract: Spray-dried granulates useful as washing or cleaning products or as components of such products, both for household and industrial use, contain at least 1 % by weight anionic surfactants and may have apparent densities of at least 550 g/l. These granulates may be produced by spraying slurries that contain saccharic acids or salts of saccharic acids. The use of saccharic acids or their salts at the same time lowers the viscosity of the slurries, so that more concentrated slurries may be sprayed, increasing the output of spraying towers without increasing their energy consumption.

Patent DE-4417237-A1 (DE)
Title: Heavy goods vehicle
Inventor: SCHMELZ HELMUT DIPL PHYS DR
IPC: B01D53/94
Filed: 1994-05-17
Abstract: On the basis of expected European emission limits for the nitrogen oxide discharge of internal combustion engines operated with excess air, especially HGV diesel engines, a device for the reduction of nitrogen oxides is to be carried in the vehicle. This device, generally functioning on the principle of selective catalytic reduction, requires a volume in the order of magnitude of approximately 0.3m<3> for an engine power of approximately 300kW. Owing to the very confined spaces in heavy goods vehicles, this amount of space seems not to be available. The invention therefore proposes that the nitrogen oxide reduction device, connected to the exhaust line of the internal combustion engine, be of cylindrical construction and arranged between a front wheel and a rear wheel of the HGV, essentially parallel to its longitudinal direction. Alternatively, the nitrogen oxide reduction device of cylindrical construction can also be arranged largely perpendicular to the longitudinal direction of the HGV, horizontally behind the driver's cab of the HGV. A further solution is obtained if the nitrogen oxide reduction device of cylindrical construction is arranged largely perpendicular to the longitudinal direction of the HGV in front of the front axle of the HGV. In this way it is ensured that in all three solutions the nitrogen oxide reduction device is arranged in a compact unit in immediate proximity to the internal combustion engine. <IMAGE>

Title: Brake pad application arrangement for disc brakes
Inventor: BIEKER DIETER
IPC: F16D65/097
Filed: 1994-05-20
Abstract: The arrangement consists of a brake pad mounting (20) over one or both sides of which a C-sectioned spring clip is mounted. The inside of the clip engages via a layer of low friction material (21), or rollers, with the side (22) of the mounting. When the brake pad is applied to the disc, the force sensed by the leading edge (12c), of the brake pad mounting (12), against the spring clip (30) will move the clip in the direction (Z) in which the brake pad is applied. One side (30b) of the clip lies against the brake pad mounting (20) and will spring the clip back to its original position when the brake is released.

Title: System and method for controlling the gear changes of a vehicle automatic transmission
Inventor: NAKASHIMA YASUHIRO
IPC: F16H59/54
Filed: 1994-06-10
Abstract: In the gear-change control system and in the gear-change control method for a vehicle automatic transmission (3), control of down-shifting on a downhill stretch of road is accomplished by fuzzy inference. When a driving-condition determination device (7B-1) ascertains that the vehicle is driving downhill, an engine-speed range setting device (7) sets an optimum engine-speed range, which is lower than a current engine-speed range. In the automatic transmission, the engagement condition of a desired engagement element (3A) is switched over to obtain the optimum engine-speed range. When the driving-condition determination device (7B-1) ascertains that the vehicle is driving downhill, with the result that the optimum engine-speed range has been set, the said range being lower than the current engine-speed range, and when no change in the engine load has been detected by an engine-load detection device (13), an engagement-condition control device (9) reduces the engagement force produced after the switching over of the engagement condition of a desired engagement element (3A) in order to obtain the optimum engine-speed range. This makes it possible to avoid a feeling that there is a discrepancy, a feeling which would otherwise occur when the transmission shifted to a higher engine-speed range. At the same time, a good gear-change response is ensured. <IMAGE>

Title: Easily disassembled (dismountable) bicycle
Inventor: JUNG STEPHAN
IPC: B62K15/00
Filed: 1994-06-16
Abstract: The handling characteristics and the design of known, easily disassembled or folding bicycles have generally been unsatisfactory and the bicycles have been relatively heavy. In addition, it has hitherto not been possible subsequently to turn a conventional bicycle into a folding or easily disassembled one. In order to turn the bicycle into an easily disassembled one, a dividable bicycle fork is incorporated which can be disassembled between the head tube (handlebar stem) and the fork bridge by means of cone fitting. The cone fitting joins the two parts in a manner which is free of play and wear and such that they can easily be detached. The bicycle according to the invention can be transported, after the assembly bolt has been undone, in two easily carried parts without any change to the stability, handling characteristics or appearance.

Title: Direction setting appts. i.e. PanPot or Panorama control e.g. for two-channel stereophony system
Inventor: MUELLER ERDMANN
IPC: H04S7/00
Filed: 1994-11-03
Abstract: The direction setting appts. is otherwise known as a PanPot, Panoramic setter or direction regulator used in a mixing desk in sound studio technology. A two-channel stereophonic signal is generated from a single channel input signal. The signal in the channel opposite the propagation direction is delayed by delta t with respect to the signal in the channel in the propagation direction. It is also attenuated by delta L relative to the other channel.For every one degree of the propagation angle measured from the viewing direction, the delay is determined by the equation delta t = 4/3 x 10 to the power -5 seconds. The attenuation delta L equals 4/3 x 10 to the power -1 dB. A tolerance of plus or minus 20 per cent is taken into account.
