Title: Indicator device
IPC: G09F11/06
Filed: 1980-12-17
Abstract: As a carrier including a wheel portion 4 is rotated about a vertical axis, restraining members 8 restrain flip- boards 2 against movement about that axis while pivot shafts 3 of the latter are between angular positions A and B on the one hand and positions C and D on the other hand. When any one of the flip-boards is thus restrained, rotation of the carrier causes torsion coil springs 1 provided on said pivot shafts to become progressively tensioned. Upon movement from position B to position C, or from position D to position A, the energy thus stored in the springs causes the flip-board to flip-over, thereby relaxing the springs except for a residual amount of spring tension. Therefore, each spring is twice tensioned and twice relaxed during one complete revolution of the carrier. The device may indicate mineral oil prices or the time. Two such devices may be arranged back-to-back with the flip- boards moving across alternately. <IMAGE>

Title: Device for regulating fuel injection quantities in diesel engines
IPC: F02D41/34
Filed: 1981-02-12
Abstract: A device for regulating fuel injection quantities provides an engine temperature dependent regulation, which is especially suited to the requirements of a diesel engine during its starting phase. The device provides, in the region below idle, optimum regulation of injection with respect to injection duration and position relative to piston top dead centre in dependence on engine temperature and engine speed, i.e. as engine speed reduces so the start of injection is advanced. On approach of the normal or operating temperature of the engine and the idling speed, a constant injection end is again provided. For realising the engine temperature and speed dependent regulation, an engine temperature dependent voltage (U1) from an engine temperature transmitter (26) is applied, in place of a voltage Up) which is product of engine speed and set load voltages, to an input (E3) of a comparison device (40) to determine the start of a pulse (IE) controlling injection duration. Limitation of the pulse length to a maximum injection duration, and thus of the injection quantity, is provided by a limiting device (45) insofar as a reference voltage (Ub) applied to the comparison device (40) does not itself terminate the pulse before its length exceeds this maximum duration. <IMAGE>

Title: Powder feeder
Inventor: ANDERSEN DENNIS
IPC: B05B7/14
Filed: 1982-12-21
Abstract: A powder feeder comprises a hopper (22) which includes a powder- containing chamber (28) bounded by upper and lower porous membranes (40,38) that are pervious to gas and impervious to powder. Pressurized gas is directed upwardly through the lower membrane to suspend powder particles of a desired size at the elevation of one or more discharge tubes (44), the inlet(s) (46) of which communicate with the powder chamber (28) between the membranes (40,38). The gas swirls while travelling through the powder- chamber (28) to produce a centrifugal displacement of particles toward a side wall of the powder chamber (28) where they gravitate toward the lower membrane (38). Accumulated powder is redistributed upon the lower membrane (38) by means of a multibladed rotor (60) which simultaneously compacts the powder. The inner end(s) of the discharge tube(s) (44) extend into the powder chamber and extend upwardly. Pressurized gas is delivered to the lower membrane (38) from a gas entry chamber (27) disposed therebelow. Heating members (120) heat the side wall (72) of the gas entry chamber (27) in order to dehumidify the gas before it reaches the powder chamber (28). <IMAGE>
