Title: Device for remote control of a vacuum cleaner blowing motor from the handle of the suction hose
IPC: A47L9/28
Filed: 1988-02-29
Granted: 1991-03-27
Abstract: In known devices of this type, only the power of the blowing motor can be controlled. The intention of the new arrangement is also to allow an indication of a necessary filter change whilst maintaining a twin-core control line embedded in the suction hose. For this purpose, an adjustable resistance element (8) with a light diode (9) is switched in series on the handle (1) of the suction hose (2). By periodic short-circuiting of this series circuit, voltage pulses are produced which are converted by means of a peak value rectifier (17) into a continuous direct voltage, by means of which the pulse length of the control pulses generated by a comparator (23) is determined. The power stage of the blowing motor (5) is controlled by the control pulses of the comparator (23). By means of a pressure switch, which is actuated at a certain degree of filling of the filter bag, the periodic short-circuiting of the series circuit of the resistance element (8) and the light diode (9) is interrupted. Illumination of the light diode (9) is effected by the now continuously present voltage. <IMAGE>

Title: Method and apparatus for production of three-dimensional objects by photosolidification
IPC: H01L21/30
Filed: 1988-02-18
Granted: 1993-08-04
Abstract: A method for forming three-dimensional objects comprises irradiating with a source (24) an uncured photopolymer (11) by transmitting an effective amount of photopolymer solidifying radiation through a radiation transmittant material (13, 16, and 23) with areas of different opacity (18-22) which leaves the irradiated surface capable of further cross-linking so that when a subsequent portion of solid object (25) is formed it will adhere thereto. In another embodiment other means of preserving subsequent cross-linking are used instead of the transmittant material. Using either method three-dimensional objects (25) can be made layer by layer or point by point.

Granted: 1992-07-29
Abstract: A particle classifier includes a generally cylindrical, air and fine particles permeable cage having a closed top and open bottom mounted to a central drive shaft. A casing surrounds the cage and defines a volute air passage about the cage with an air separation zone between the volute and the cage. A generally tangential air inlet is provided in casing volute and a material inlet is provided in the the upper end of the casing. A stationary chamber is positioned below the cage for the air and fine material which enter the cage. From the chamber, the air and fine material is directed to cyclone separators in which the air is separated from the particles. A hopper is positioned below the chamber for collecting coarser material which fails to enter the cage. The size of the volute can be adjusted by a vertical partition within the casing. The partition allows flexibility in setting the air velocity. Means are provided for stream-ling the air flow from the air inlet to the cage and retaining particles in the separation zone. In one case. louvers are provided for these two purposes, and in another case a screen is provided between the volute and particle separation zone.

The first terminal thereof is connected to the second terminal of the first voltage sensitive switch (30), and the second terminal thereof is connected to the ring line (R). A third voltage sensitive switch (34) includes first and second terminals. The first terminal is connected to the second terminal of the first voltage sensitive switch and to the first terminal of the second voltage sensitive switch. The second terminal of the third voltage sensitive switch is connected to ground potential. The switches are conductive when a respective voltage threshold is exceeded. In one embodiment, the sum of the voltage thresholds of the first and third voltage sensitive switches is approximately equal to the sum of the voltage thresholds of the second and third voltage sensitive switches, such that the circuit is conductive when either of the thresholds of the first and third voltage sensitive switches or the second and third voltage sensitive switches are exceeded. In another embodiment, the holding current of the third voltage sensitive switch is lower than that of either the first or second switch. In this combination, the third switch turns on first, then both the first and second switches turn on in unison and hold the lines in balance during switching.
