Title: Circuit arrangement for the matching of catalytically active measuring sensors for measured variable pick-ups
Inventor: HOEHT WOLFGANG ING GRAD
IPC: G01N27/16
Filed: 1988-05-06
Abstract: The invention relates to a circuit arrangement for the matching of catalytically active measuring sensors for measured variable pick-ups. In the production of catalytically active measuring sensors, a non-uniformly developed catalyst surface can arise on the pellet element, as a result of which the measuring sensitivity can change and vary over a wide range. In order to be able to match such measuring sensors optimally, a fixed resistor is arranged, according to the invention, in the bridge arm having the catalytically active measuring sensor, in parallel with this measuring sensor, or a potentiometer is connected downstream of this fixed resistor, on which potentiometer the heating power of the catalytic measuring sensor can be adjusted to an optimal value and fixed (Fig. 2). <IMAGE>

Title: Foot-pedal drive
IPC: G10D13/00
Filed: 1988-08-03
Abstract: In contrast to that of a conventional foot pedal, this drive consists of the pedal known from OS 3731992 A1 or a pedal (1) designed at an angle of 120@-140@. The front pedal part is connected to the beater mounting (2) which has to have a round, disc-shaped construction of given diameter, by means of a band or a belt (3). By means of a rocking movement of the foot (sole on the front, heel on the rear pedal part), the desired (double) tempo is transmitted to the beater (4). A bossa, salsa, shuffle or whatever it might be can be produced effortlessly with the pedal. At the same time, the second foot remains on the hi-hat. <IMAGE>

Title: Coupling a sound-emission pick-up to a sound-emitting or sound-transmitting part
Inventor: SLIVA EDUARD DIPL ING
IPC: G01N29/28
Filed: 1988-09-26
Abstract: In order to enable a simple exchange of the sound-emission pick-up (1) under uniform conditions of the coupling, it is provided that     - the sound-emission pick-up (1) is mounted on a vessel (2),   - the vessel (2) contains a liquid coupling medium (3) and - the sound-emitting or sound-transmitting part (4) dips into the liquid coupling medium (3). Sound emission pick-ups (1) held in reserve can then already be mounted beforehand, by means of a hardenable coupling adhesive (5), on to the vessel (2), that is to say the exchange is not delayed by the long hardening times of about 8 to 10 hours of the coupling adhesive (5). In sound-emission analysis, on exchanging the sound-emission pick-up (1), a renewed calibration of the measuring chain can be dispensed with as a result of the constant coupling conditions. <IMAGE>

Patent DE-3843827-A1 (DE)
Inventor: WAHNSCHAFFE JUERGEN
IPC: F01M1/16
Filed: 1988-12-24
Abstract: An internal-combustion engine having two hydraulic fluid circuits which are connected in parallel and are supplied by means of a bypass restrictor on the control valve, from a source having a pump. Hydraulic circuits having two parallel loops in a supply unit which are supplied by means of a pump and in which one circuit has control valves with a specific opening pressure and with a specific flow characteristic generally provide an inadequate supply to one of the two loops under specific transient, operationally-dependent conditions. In the case of the fluid circuit with valves, one control valve is integrated with a bypass restrictor, as a result of which the inadequate supply of the loop provided with valves is circumvented such that a minimum supply of this loop is made possible even when the valve is closed. <IMAGE>

Title: Blocking apparatus which is intended for integration into carriageways and acts against land-bound vehicles
Inventor: BETZING PETER
IPC: E01F13/02
Filed: 1989-01-11
Abstract: In the case of known blocking apparatuses, in which the automatically extendable blocking elements are accommodated beneath the road surface, extended foundations which are deep and thus are visible from the outside are necessary. The novel apparatus is intended to have a high blocking action, to be erectable rapidly and by hand, to be cost-effective to produce and to be unobtrusive so that it cannot be sabotaged or destroyed. The blocking apparatus which acts against land-bound vehicles comprises a plurality of blocking elements 10 which are directed towards one another at predetermined spacings and can be anchored in foundations. The blocking apparatus is suitable for integration into all relevant carriageways and acts, in particular, against tracked vehicles. <IMAGE>

Patent DE-3905493-A1 (DE)
Title: Locating and navigating system for land vehicles
Inventor: KNOLL PETER PROF DIPL ING
IPC: G01C21/34
Filed: 1989-02-23
Abstract: A locating and navigating system is proposed in which the driving route can be entered in a simple and memory-saving manner by entering node points. Since the street plan is also determined by entering node points, a considerably smaller memory is required in comparison with previous systems using digitised streets. In the driving information output the driving route which has been entered is output in a clearly visible manner in addition to the street plan. Additional abstract route-guiding symbols which are also mirrored on head-up displays, for example on windscreens in the field of view of the driver, and are possibly supported by acoustic announcements, result in a clearly laid out driving information output. <IMAGE>
Patent DE-3907504-A1 (DE)
Title: Turbine with a double spiral structure
Inventor: YANO SHUNJI
IPC: F02B37/24
Filed: 1989-03-08
Abstract: The invention relates to a radial flow turbine which combines a double spiral structure and a nozzle structure with a variable area. The said turbine is suitable for use as an exhaust turbine of a turbocharger for the internal combustion engine of a vehicle. The first spiral passage 25, 43 has no control device for the flow, whereas the second spiral passage 26 has a variable nozzle unit 28, so that only the first spiral passage 25 together with the essentially closed second spiral passage 26 is used in the low engine speed range. The variable nozzle unit 28 is actuated only when the engine speed is reduced below a certain value. Alternatively, it is possible, by providing a control valve 27, 45 in the first spiral passage 25, 43, to adjust the nozzle unit 46, the valve 45 with the variable area being kept closed in the low speed range, and to open both the nozzle unit 46 with the variable area and the control valve 45 in the high speed range. In each case, the operating condition of the turbine can be precisely adjusted without creating an excessive counter pressure or back pressure at its inlet end or causing any shocks or decelerations over the entire speed range. <IMAGE>
Patent DE-3911729-A1 (DE)
Title: Hydraulic system for telescopic jib crane - provides independent control of jib sections permitting simultaneous telescoping
Inventor: BLASE HELMUT DIPL ING
IPC: B66C23/70
Filed: 1989-04-11
Abstract: In a common design of telescopic jib crane the individual sections of the jib can only be hydraulically actuated in sequence. As a result of this telescoping is slow. The modified system overcomes this disadvantage by providing separate oil supplies (4,5,6) to the hydraulic cylinders of each jib section (1,2,3) by way of the hydraulic regulator valves (11,12,13). Thus each jib section can be telescoped simultaneously and, depending on the particular usage of  the crane, partially telescoped if desired. USE/ADVANTAGE - Telescopic jib crane with rapid telescoping and more uniform distribution of stresses in jib.

Inventor: KRAMMEL HORST
IPC: B60R22/18
Filed: 1989-04-22
Abstract: The invention concerns a holder (1) for a vehicle safety belt (7) with automatic reeling. The automatic reeling mechanism is located in a region behind the back (4) of the rear seat and the safety belt (7) runs forwards from there via the belt holder (1) to a passenger. The belt holder (1) consists essentially of an arm (2) one end of which is connected via a coupling device (3) to the vehicle body in the region behind the seat back (4) and the free end of which carries guide means (head (5)) for the safety belt (7). The coupling device (3) consists of a first coupling with an approximately vertical axis of rotation (7) and, in a further embodiment of the invention, a second coupling with an approximately horizontal and perpendicular axis (14). This gives better safety belt guidance and enables the belt to be more easily adapted to different passenger sitting positions and different passenger sizes. Further developments of the invention call for the head (5) to be rotatably connected via an axis (16) with the arm (2), permitting different angles of rotation to be set about the first axis of rotation (7) by means of a press-on arresting device (12).
