Patent DE-4325025-A1 (DE)
Inventor: ROTH BERND
IPC: B61K7/02
Filed: 1993-07-26
Abstract: The invention relates to a rail brake system for marshalling yards, having at least one group of brake elements (5) which are attached one behind the other to the rail web and can be moved out of an inactive home position into an active braking position using an electric control, at least one control line which is common to all the brake elements (5) and to which actuator elements (9) which are assigned to the brake elements (5) are connected being provided. The electric connection power of such a rail brake system is substantially reduced by providing a locking line (V) and an unlocking line (E), by assigning to each actuator element (9) a locking switch (II) which is actuated thereby and arranged in the locking line (V), and an unlocking switch (I) which is actuated thereby and arranged in the unlocking line (E), and by connecting the actuator elements (9) electrically into the circuit which leads from the switches to a return line (R) in such a way that the actuator elements (9) are actuated successively in a cascade-like manner. Alternatively, the invention provides for the actuator elements (9) to engage on associated locking elements (8) which can be moved between a position of rest in which they are disengaged from the brake elements (5), and a locking position in which they hold the brake elements (5) in the inactive home position.

Title: Safety system for autonomous motor vehicle - contains detector of changes in detection region of obstruction detector eg ultrasound radar
Inventor: UEMURA HIROKI
IPC: G01S15/86
Filed: 1993-08-03
Abstract: The safety system contains an obstruction detection arrangement (36) for detecting obstructions in the forward path of the vehicle. Another detection arrangement detects deviations of a detectable region of the path, which can be detected by the obstruction detector, from a region which can be detected when the vehicle is moving along the path under normal conditions. A safety mechanism conducts a process whereby the vehicle is safely guided along the required path when a deviation from the path is detected. The detection arrangement can detect a reduction in the detectable region. USE/ADVANTAGE - The system improves the safety of the operation of the autonomous vehicle, even when the detectable region of an obstruction detector, e.g. a radar device, changes.

Title: Power station process
Inventor: RUETER BERNHARD DIPL ING
IPC: F23K3/02
Filed: 1993-08-26
Abstract: The invention relates to a power station process in which the combustion of brown coal (lignite) with air produces at high temperature a flue gas which is sucked in by a fan mill, the brown coal being dried and ground. The water contained in the brown coal emerges as water vapour and is fed together with the sucked-in flue gas to a moisture separator where it is separated from the ground brown coal. The vapour produced is expanded in a turbine and is finally present as feedwater which is fed anew into the steam generator. It is the object of the invention to improve the boiler efficiency of the steam generator (1) and the thermal efficiency of the low-pressure stage (23) of the steam turbine. The object is achieved when the gas mixture (42) of water vapour, flue gas and air is fed on a direct path (44) to the feedwater preheater (31) where it gives up its heat to the feedwater (29). Liquid water vapour condensate (45) is extracted from the feedwater preheater (31). In addition, a gas mixture (46) containing predominantly non-condensable gaseous components emerges from the feedwater preheater and is fed via a line (48) and branch line (49) to the suction line (6) of the fan mill (7). A subquantity of the gas mixture (46) is fed, together with the preheated combustion air (16) and the ground coal (41) to the burner (4) via a further branch line (50). A possible ...

It has a sloping edge at a given angle (alpha) to the top surface so that the small blade starts with a deep cut, tapering to a shallow cut. USE/ADVANTAGE - Double circular saw machine reduces or eliminates splintering at edge of piece of laminated wood.

Title: Controlling circuit using a number of sensors
Inventor: GLEIM GUENTER DIPL ING
IPC: H03K5/08
Filed: 1993-09-20
Abstract: To control the speed of and/or commutate a motor, it is known to allocate to the motor a number of sensors which generate a number of similar, mutually phase-shifted sensor signals indicating the rotor position. From these, control signals for the commutation or the speed control are obtained in comparators having a hysteresis. In practice, disturbances which, for example, originate from the motor coils and influence the evaluation are superimposed on the signals at the outputs of the sensors. The object is to construct a circuit of the said type in such a manner that it is capable of suppressing disturbances even when the motor is standing still, and maintains this capability without time limit. According to the invention, circuit means are provided which have the effect that the amount of the hysteresis at the comparator (A) for a sensor signal (a) is in each case dependent on the amplitude of one or more of the other sensor signals (b, c). The sensor signals are preferably supplied to an OR stage (Da, Db, Dc), the output voltage of which controls the hysteresis at the comparators (A, B, C). The circuit is especially suitable for controlling the speed of, or commutating, a capstan motor in a video recorder. <IMAGE>

Abstract: - Field of application: The invention has applications in reciprocating piston engines, especially in four-stroke internal combustion engines. These include four-stroke spark ignition engines, diesel engines, multi-fuel engines, etc. - Operating principle of the DZM-D: The inlet and exhaust control in the rotary cylinder engine double nozzle is characterised in that, due to the reciprocating movement of the engine piston, the associated rotation of the crankshaft is converted by way of a gear fixed thereon in order to drive the rotary movement of the engine cylinder. Due to rotation of the engine cylinder the inlet and exhaust of the gas mixture are controlled by way of four opening ports. Due to the transmission ratio of the gears, 1 rotation of the engine cylinder and, with 2 inlet and exhaust nozzles, 2 ignitions of the gas mixture are performed for 4 revolutions of the crankshaft. <IMAGE>   - Advantages of the invention:   - Simplified engine construction due to the absence of valves, camshaft, timing chain - More rapid and more complete mixture charging possible due to 2 inlet nozzles - Attainment of the absolute timings in charging and discharging of the combustion chamber due to opening ports   - Increased crankshaft revolutions   - Engine power increase - Due to rotary movement of the cylinder an improved swirling of the ...

Filed: 1994-08-12
Abstract: The safety mechanism is built into a fastener that comprises a pistol shaped housing with a cylinder section (2) and a chamber section (3) which connects to a compressed air supply. In the cylinder section is a piston (8) which connects to a push rod. A location rod (12), which at one end engages in a slot in the push rod has a conical attachment at the other end which accepts the fastener (14). A switch (16) is fixed by means of a stud (17) to the location rod and has a surrounding collar on which a switch pin is fixed which in turn is in contact with the end of a start-plunger (20). The start plunger is connected via a lever with a trigger (22). The lever also operates a valve connected via a tube (25) to the chamber.
