Patent DE-3839339-A1 (DE)
Title: Conveyor belt for bulk material
Inventor: MEYER THOMAS DIPL ING
IPC: B65G39/16
Filed: 1988-11-22
Abstract: Disturbing forces (rain, wind, eccentric feeding of material) cause endless conveyor belts to run off track or "wander". To prevent running off track, fixed, trough-like sets of rollers with a positive camber are used. Such sets of rollers are heavy, however, and can only be adapted with a considerable effort when the inclination or the conveying direction of the conveyor belt is to be altered. The new conveyor belt is intended to prevent off-track running even in the case of different inclinations and conveying in opposite directions. The supporting rollers (9, 10) of at least some of the garlands (8) in the region of the upper run (7') are coupled to one another in a longitudinal direction and are jointly adjustable to a camber(s) which can be predetermined. In addition, at least some of the garlands (13) in the region of the lower run (7'') are also coupled to one another in a longitudinal direction and can be set to a camber which can be predetermined. The garlands (8; 13) can be adjusted from an easily accessible central point even when the conveyor is running and are therefore especially well suited for large belt systems. <IMAGE>

Abstract: The invention relates to a motor vehicle passive restraint system comprising a gas generator for inflating an air bag attached thereto. The generator (10) comprises a mounting plate assembly (12) having a base plate, a recessed portion (18) for receiving and supporting a diffuser plate (22) and means for receiving and attaching the air bag (32). The mounting plate assembly is integrally constructed of a relatively light weight material capable of being stamped utilizing conventional stamping equipment. The generator additionally comprises a diffuser plate (22) with a plurality of gas exhausts (30). The diffuser plate (22) further comprises a support plate configured for connection to the recessed portion of the mounting plate assembly, and at least one integral side wall portion extending from the support plate. The diffuser plate (22) is connected to the mounting plate assembly (12) in a manner to permit a minimal degree of separation between the diffuser plate and the mounting plate assembly in the event the system becomes over-pressurized. Included within the generator is a gas generant composition. The mounting plate assembly and diffuser plate form a housing for this gas generant composition. <IMAGE>

Patent DE-3910895-A1 (DE)
Title: Control arrangement independent of load for hydraulic consumers
Inventor: KAUSS WOLFGANG DR ING
IPC: F15B11/00
Filed: 1989-04-04
Abstract: A control arrangement independent of load for hydraulic consumers is described which is equipped with a control unit for the consumer and a directional control valve which can be controlled independently of the control unit. The directional control valve has a blocking position as well as a through position in which a control line carrying the load pressure is connected to the tank. The control unit is designed as a servo valve which together with the directional control valve can be operated from the same control source via a common control line. In order to provide the transition from the stand-by operation to the flow-control function with a rapid response characteristic, the directional control valve is controlled in such a way that it is switched from the through position into a blocking position before the servo valve is opened in a controlled manner. To minimise the pump circulation losses in stand-by operation with a fixed-displacement pump, the common control pressure line can be fed by the pump pressure via a pilot-controlled pressure valve and is fastened via a non-return valve to the control line carrying the load pressure, which is connected to the control side of a pressure-relief valve for the pump circulation pressure.

Abstract: A directional control valve, in particular for high-pressure hydraulics, in the housing of which a location bore (5), running transversely to the spool bore from an outer side of the housing right into the spool bore (2) and intersecting a supply bore (14), contains a pressure balance (DW) which has a regulating piston (27), adjustable as a function of pressure, for varying the passage size of the regulating orifice (R). The regulating piston (27) is acted upon in opposite directions on the one side by the load pressure and a regulating spring (39) and on the other side by the pressure downstream of the regulating orifice. In this directional control valve, the regulating piston (27) is adjusted in the direction away from the spool bore (2) to close the regulating orifice (R) and is loaded towards the spool bore by the regulating spring (39) arranged on its side remote from the spool bore. <IMAGE>

Extract is returned through a valved conduit to the distn. container. A control unit is linked with the heater for the destn.m container to the pump, level sensor and monitoring thermometers. On completion of extn. the extract conc. in vessel is discharged from an outlet; extn. medium itself is discharged from the storage vessel via a base outlet. USE/ADVANTAGE - For treating medium amts. of stock, e.g. 50-500 l in reasonably short time and acceptable consumption of extra medium.

Title: Vehicle heater blower for air-conditioning system - has automatic connection for load resistor when in heating mode
Inventor: GRADMANN GERHARD DIPL ING
IPC: B60H1/00
Filed: 1990-01-29
Abstract: The fresh air heater/ventilation system of the vehicle includes one- or two blower motors (10, 12) which drive the fresh air or the heated air. When the system is set into the heating mode the motor speed is reduced by a load resistor (18) which is automatically switched in series with the mode. This ensures that the motor does not overheat through the reduced cooling effect of the warm air. The load resistor can be one of the stepping resistors which reduce the motor speed, thereby saving an additional component. An alternative system switches the two blower motors in series when in the heating mode. ADVANTAGE - No overheating problem for blower motor, no need to use heavy duty motors.
