Title: Exhaust emission controller for IC engine - has tubular filter elements with regenerative heaters embedded in thickened walls and mounted in tubular housing
Inventor: IIYAMA AKIHIRO
IPC: H05B3/10
Filed: 1993-02-08
Abstract: The controller has the tubular housing (10) with an exhaust entry (10a) at one end and the outlet (10b) at the other end. A bulkhead (10e) separates the housing into inlet- and outlet chambers and the filter elements (11) are mounted on the bulkhead, open ends to the inlet chamber. The heater rods (12) are embedded in the walls of the filter elements in thickened sections. The filter is made from foamed ceramic or sintered metal. The porosity reduces with carbon uptake. To regenerate the filters the heaters are operated to burn off the carbon. Several filter elements are spaced on the bulkhead. ADVANTAGE - Long periods between regeneration, large flow capacity.

Title: Friction coupling for road vehicles - has pressure plate non-rotatably connected to housing and axially located
Inventor: MAUCHER PAUL
IPC: F16D13/58
Filed: 1993-03-03
Abstract: Axially between the pressure plate (3) and a cover (2) is a pressure plate spring, which is pivotable around a ring-shaped pivot bearings (5) borne by the housing, and activates the pressure plate in the direction of a counter pressure plate (6) fixed to the housing. The friction lining (7) of the coupling plate (8) is tensioned between the friction surfaces of the pressure plate and the counter pressure plate. The pressure plate is non-rotatably connected to the housing (2) via leaf springs. The plate spring has a ring-shaped basic body (4a) applying the pressure force, from which radially inwardly operating tongues (4b) extend. The plate spring is thus so installed that with radially further outward areas it activates the pressure plate (3) and is tippable with radially further inward areas around the pivot bearing (5). USE/ADVANTAGE - An automotive friction coupling with improved adjustment means.
Patent DE-4319322-A1 (DE)
Inventor: MUELLER JOSEF DIPL ING
IPC: G01D5/16
Filed: 1993-06-11
Abstract: The position sensor according to the invention exhibits a sensor (3), the output signal (Sd) of which is dependent on the distance (d) between a measurement division (1) and a scanning unit (2). So that the distance-dependent measurement signal (Sd) is independent of temperature changes, the sensor (3) consists of a voltage divider circuit with an active branch (4) and a supplementary branch (5). In the active branch (4), magnetoresistive elements (41) are arranged which scan the measurement division (1). In the supplementary branch (5), resistive elements (51) are arranged which have the same temperature characteristics as the magneto-resistive elements (41) of the active branch (4) but have no sensitivity to magnetic fields. The voltage across the active branch (4) is the distance-dependent measurement signal (Sd) by means of which the amplitude of the position-dependent scanning signals (S1, S2) of the measurement division (1) can be regulated. <IMAGE>

Patent DE-4327909-A1 (DE)
Title: Linearly guided air spring
Inventor: HESS ALBERT
IPC: B60G9/02
Filed: 1993-08-19
Abstract: The aims or results of the invention, reduced to the lowest common denominator are as follows:   1. The use of the existing air spring bellows is retained, but with a special role! 2. Air spring bellows + telescopic device + emergency running or limit stop produce the  "linearly guided air spring",  as can be used generally in mechanical engineering. 3. For wider use in the vehicle sector, principally for axle fittings, the linearly guided air springs are equipped with wheel alignment bearings, which ensure tilting of the axle and simultaneous articulated attachment thereto. 4. Stabilisation on front and rear axle is superfluous. This is virtually a benefit of the constrained horizontal position of the chassis, which excludes rolling movements by way of the spring. 5. In contrast to the existing suspension curves resulting from the suspension link guiding, the vertical right-angled suspension achieved in the vehicle longitudinal direction brings technical and kinematic advantages which also have an advantageous influence on the steering kinematics. 6. The weight saving from the use of the linearly guided air springs is approx. 200 kg in the case of a two-axle vehicle. In the case of suspension link-guided axles this figure is approx. 400 kg. That means at least 200 kg more payload. 7. The agony of having to choose whether the telescope is outside or inside is to be gauged with reference to the space available and the requirements for use, and ultimately to the strength. For fixed engines, in which...   Original abstract incomplete.

Title: Sensor for determining inclinations, angles or horizontality
Inventor: DOBLER KLAUS DR ING DR
IPC: G01B11/26
Filed: 1993-09-27
Abstract: In the case of a sensor for determining inclinations, angles or horizontality, there is a radiation source (20) in the housing (10) or as a separate built-on device, using which radiation source a direction-finding beam (25) running along the measuring surface (11) of the sensor is produced. With the aid of this direction-finding beam (25) it is possible to extend the actual measuring surface (11) and to fix on or find the position of remotely lying marking points (15). The range of use of the sensor is thereby considerably broadened. <IMAGE>

IPC: G10D3/06
Filed: 1994-07-22
Abstract: Markings are applied to the fingerboard depending on the selected tonal system and instrument tuning or pitch to enable the player to find the intervals. Marking is effected by a change in material or a change in the board surface, possibly by colouring this, and it is also possible to mark the fingerboard out the abstract and/or concrete tone names. These help the player to find octaves, fifths, thirds, seconds and unisons in composition reading etc. In a six-stringed guitar, the fingerboard is marked out in black and white to indicate the intervals in a diatonic system tuned to 444434. For a 4-stringed diatonic violin, in tuning 5555, the board markings are shown by abstract tone names.
