Title: Brake assembly with incorporated brake booster
Inventor: LEIBER HEINZ DIPL ING
IPC: B60T13/14
Filed: 1987-07-18
Abstract: In a brake assembly designed in a twin construction with incorporated brake booster, two master cylinders are operated by way of a moment-balanced rocker. The rocker can be displaced with the piston of a drive cylinder of the brake booster, the pressurisation of which by the outlet pressure of a brake valve, proportional to the pedal force, boosts the braking force. The movable limit of the drive pressure chamber is formed by a two-part piston, which comprises a central piston section, to which the rocker is immovably fixed, and an annular piston, capable of displacement on the central piston section, which annular piston, viewed in the pressure build-up displacement direction, can be supported on a stop step of the central piston section. Between the annular piston and an end wall of the drive cylinder housing, through which the central piston section passes, on which the bearing block of the rocker is fixed, an annular chamber extends, which is connected in the basic position of a booster control valve to the reservoir of the servo pressure source. This connection can be shut off by reversing of the said valve, as a result of which the annular piston is hydraulically locked and only the cross-sectional area of the central piston section is still operative for boosting the brake force.

Title: Safety binding for a winter sports apparatus (snowboard, snowsurfer or the like)
Inventor: HAAS CHRISTOPH
IPC: A63C10/08
Filed: 1988-03-18
Abstract: The invention relates to a safety binding for a winter sports apparatus (e.g. "snowboard, snowsurfer"), which, before forces capable of injuring bones, ligaments and joints are reached in the event of lateral tilting of the ankle in the direction of travel or counter to the direction of travel, releases a binding plate to which the ski boot is firmly fixed. The current binding plate is not screwed to the sporting apparatus but fixed by means of pins or strips which are fixedly mounted on the sporting apparatus and engage into corresponding recesses on the underside of the binding plate, in a horizontally displaceable manner. The vertical displaceability of the binding plate is limited by latching or tilting mechanisms mounted to the side of the binding plate. These latching or tilting mechanisms engage on appropriately modified supports which are affixed laterally on both sides of the binding plate. As a result, release of the binding plate is possible above an individually adjustable force. Furthermore, the release of one binding provokes the opening of the second binding, so that simultaneous release of the two binding plates and hence of the two legs results. This simultaneous release of the second binding plate is achieved in that the spring force released, which arises when the first binding plate is released, is utilised to ... a locking mechanism on the release mechanism of the second ...

Title: Device for edge-mill charging of the runners rotating on the spot with rotating grinding and grid tracks
Inventor: SOGL RUPERT DIPL ING
IPC: B02C15/14
Filed: 1988-06-11
Abstract: The charging of this edge mill takes place continuously and uniformly on the entire width of the grinding track with the material-feed belt (3). Both the grinding track and the grid track have their own tracks which extend about the entire circumference. The edge-mill bed (10) is constructed so as to rotate so that the runners (6) rotate on the spot. By this means, the large power losses are avoided. Lighter runners can now be used with the same processing effect which also results in a correspondingly large saving of the power to be expended, makes possible a lighter edge-mill design and, overall, leads to substantially more favourable manufacturing and operating costs. The said edge mill can optionally be equipped with an upper or lower drive. <IMAGE>

Filed: 1988-08-13
Abstract: To analyse the oxidable substances, for example the chemical oxygen demand (COD), contained in an aqueous sample liquid, for example sewage water, the aqueous sample liquid is diluted with dilution water and fed into a reaction container (2) where it is mixed with ozone from an ozone generating device (7). After passing through a second reaction container, for example a tubular reactor (12), the sample liquid reaches an ozonometer appliance (13). Ozone being added continuously, the ratio of sample liquid to dilution water of the mixture is regulated in such a manner that the residual ozone content measured by the ozonometer appliance (13) remains constant at a predetermined level. The ratio of sample liquid to dilution water of the mixture required to maintain the reading on the ozonometer at said level is used to determine oxidable substances contained in the water, in particular COD.

Title: Method and device for adjusting the entry level of the body of a road vehicle
Inventor: ABT ALBERT
IPC: B60G17/052
Filed: 1988-12-23
Abstract: A method and a device for adjusting the entry level, that is the height above the ground of the body of a passenger-carrying road vehicle, especially a bus. Buses of this type have air suspension bellows (7) between their axles (4, 5) and the body, which serve for suspension and which are supplied with compressed air at suitable pressure from a pressure reservoir (9). The invention lies in the fact that the body is lowered only in relation to that axle (4) which is adjacent to the entry door (1). For this purpose, air is released from both air suspension bellows (7) seated on the said axle in order to lower it. To raise it again, air is fed into the two air suspension bellows (7) from the pressure reservoir (9). The invention is of particular importance where the entry door is the door nearest the front of the road vehicle. To accomplish this a control valve, which ensures that air is either fed into the said air suspension bellows from the pressure reservoir or is released from the air suspension bellows, is arranged in the course of a pressure line (10, 14, 18), which leads from the pressure reservoir (9) to one of the said air suspension bellows (7). <IMAGE>
