Patent NO-168381-C (NO)
Inventor: FUSS F H
IPC: E05B47/00
Filed: 1987-04-30
Abstract: An electric door opener with a changer freeing or blocking a latch is described, which changer is detachably engaged with an electromagnetically operable inner armature. An electromagnetically controllable locking device prevents disengagement of the inner armature from the changer, e.g. as a result of an impact. The locking device has a locking lever provided with a detent and a control edge. The lever engages a corresponding projection on the inner armature. An outer armature acting on the control edge initially deflects the locking lever to overcome the locking action and, after a predetermined forward movement, drives the inner armature to release the changer.

Abstract: An arrangement for the transport of goods in bulk, such as cereal grain, by air flowing through a perforated base plate. The arrangements are provided in areas of the base plate (1) adjacent to the perforations (7) to impart to the air flowing through at that point a movement component running along the base plate (1), where a minimum quantity of air is required in order to transport the desired quantity of goods in bulk. The perforations (7) consist of elongated slots running across the direction of flow, that is to say the direction of feed. The slots are laterally displaced in relation to the slots in front of and behind them in an unsymmetrical manner, such that they form diagonal rows (B:C), the angles ( alpha : beta ) of which to the direction of transport (A) are considerably smaller in one lateral direction than in the other, when measured from one of the slots.

Granted: 1996-12-17
Abstract: A method for realizing, and a structure for implementing a switching network employing 2x2 switches. The network is dilated in that none of the 2x2 switches concurrently carry an active signal. The method for realizing such a network alters a given non-dilated network by replacing each 2x2 switch in the non-dilated network with a dual rail switch haing a pair of 2x2 interconnected switches, and by replacing each link in the non-dilated network with a pair links. The final output of the dilated network is obtained by adding a combiner final stage which combines the pairs ofsignals to form output signals that parallel the output signals of the given non-dilated network.

Title: Strobe alarm circuit
Inventor: BOCAN KENNETH J
IPC: H05B41/34
Filed: 1992-07-02
Granted: 2000-05-02
Abstract: A strobe light circuit for flashing a flashtube at a desired frequency includes a transformer the primary of which is repetitively connected and disconnected across a D.C. power source by a switch so that energy stored in the primary winding during closed periods of the switch is transferred to the secondary winding of the transformer, with a step-up in voltage, during open periods of the switch, and through a diode to an energy-storing capacitor connected in parallel with the flashtube. The closed period of each switch cycle is initiated at regular intervals by a timing signal and the open period is initiated in response to the attainment of a predetermined voltage across a capacitor connected across the power source indicating that sufficient energy is being stored in the primary winding during each cycle such that the energy transferred to the energy-storing capacitor during the open period of all cycles occurring during one flash period will be sufficient to enable the flashtube to produce a flash when triggered.      A flash unit associated with the flashtube includes a trigger circuit that responds to two closely following trigger pulses to produce a double flash during each flash period. The flash rate is constant over a range of input voltages and the light intensity of each flash is independent of variations in capacitance of the energy-storing capacitor.

Title: Dark decay control system utilizing two electrostatic voltmeters
Inventor: SCHEUER MARK A
IPC: G03G15/01
Filed: 1992-08-25
Granted: 1999-02-16
Abstract: A single pass tri-level imaging apparatus and method. Compensation for the effects of dark decay on the background voltage, V Mod, and the color toner patch, V tc readings is provided using two ESVs (ESV1 and ESV2), the former located prior to the color or DAD housing and the latter after it. Since the CAD and black toner patch voltages are measured (using ESV2) after dark decay and CAD voltage loss have occurred, no compensation for these readings is required. The DAD image voltage suffers little dark decay change over the life of the P/R so the average dark decay can be built into the voltage target.

Title: Programmable noise bandwidth reduction by means of digital averaging
Inventor: POKLEMBA JOHN J
IPC: H04B1/10
Filed: 1992-07-16
Granted: 1999-10-26
Abstract: A pre-averager for digitally averaging the samples of an input data signal (26) over two or more symbols, the averaging interval being defined by the input sampling rate divided by the output sampling rate. As the averaged sample is clocked (290, 29e) to a suitable detector at a much slower rate than the input signal sampling rate the noise bandwith at the input to the detector is reduced. The pre-averager forms a data filter (50a, 50b, 50c, 50d) having an output sampling rate of one sample per symbol of received data. More specifically, selected ones of a plurality of samples accumulated (28a, 28b, 28c, 28d) over two or more symbol intervals are output in response to clock signals at a rate of one sample per symbol interval.      The pre-averager includes circuitry (40, 44) for weighting digitized signal using stored finite impulse response (FIR) filter coefficients (42).
