Title: Electrically driven door lock
Inventor: SCHOLZ ERWIN
IPC: E05B47/00
Filed: 1988-12-09
Abstract: The electromotively driven door lock has a bolt (29) which is guided displaceably in a lock case (7) and which is coupled in the two directions of movement, via a push-face mechanism (61, 63), to a control part (43) displaceable transversely relative to the direction of movement of the bolt (29). The control part (43) is driven by an electric motor (37) via a gearwheel mechanism (41) and a rack toothing (59) provided on the control part (43). The electric motor (37) can move the control part (43) beyond the position assigned to the drawn-in bolt (29) towards a latch (9) of the door lock, the control part (43) taking up the latch (9) in the drawing-in direction. For this part of its stroke, the control part (43) can be driven pivotably or else take up the latch (9) via a sloping-face mechanism or a deflecting angle lever. The follower (21) provided for the manual opening of the latch (9) takes up the control part in the drawing-in direction of the bolt (29) via take-up stops (81, 83), so that, if necessary, the door lock can also be released manually. <IMAGE>

Abstract: A half current switch comprising: at least one input transistor (16), a load resistance (42, 44) connected between a first voltage reference and the collector of the input transistor, a constant-current resistance (32) connected between the emitter of the input transistor and a second voltage reference, and a feedback means including at least one feedback connected to the constant-current resistance. The feedback means further includes means for biasing the feedback transistor (36) to drive a current through the constant current resistance (32) which, when flowing, increases with an increasing main current and decreases with a decreasing main current through the input transistor. The feedback means thus causes a constant current to be drawn by the input transistor (16) when it is conducting, thereby controlling the capacitance of the input transistor while maintaining the output level constant. 
     In a preferred embodiment, the feedback means comprises a PNP transistor with its base connected t the collector of the input transistor, with its emitter connected to the first voltage reference, and with its collector connected to the emitter of the input transistor. The PNP transistor not only acts as a feedback device to control current, but also acts to prevent oscillations when a speed-up capacitor (54) is used in the circuit.

Abstract: A heating apparatus (10) is disclosed for hea­ting a calender roll (12). The heating apparatus (10) utilizes heat supplied by induction heating and from a heat transfer medium. The heating apparatus (10) includes heating channels defined by the roll (12). The channels extend through the roll (12) such that the heat transfer medium is permitted to flow through the channels so that heat is transferred from the transfer medium to the roll (12). An induction heater (14) is disposed adjacent to the external surface (24) of the roll (12) and extends along substantially the entire length of the roll (12) such that when the induction heater (14) is energized, heat is induced in the region of the external surface (24) of the roll (12) for supplementing the amount of heat transferred from the heating medium so that the temperature of the external surface (24) of the roll (12) is increased to a level which, in the absence of the induction heater (14), would cause excessive shell stress. Furthermore, the temperature level is attainable without the hazards associated with the use of a heat transfer medium operating at least at such temperature level.

Abstract: A nonlinear feedback control method and apparatus for an internal combustion engine in which a model of the engine is constructed, and load torque is estimated as a variable representing the operating state of the engine. Deviations of the engine from the engine model are formulated as disturbances. Other variables which cannot be measured are determined by making experiments and using tables. Based on the estimated load torque, the formulated deviations and other formulated variables, precise feedback control is executed for the engine, which varies in its operating conditions so that the rotation speed of the engine is adjusted to a target rotation speed by controlling a throttle opening. The estimated load torque is a physically significant control quantity which is easy to manipulate, and which can also be used for various controls such as an ignition timing control and a fuel injection control.

Abstract: A method of characterising a material uses an element (34) in which microwaves can propagate and can resonate, such as a weakly-coupled isolated microstrip device or a microwave cavity, arranged so that fringing fields from the element interact with the material. Microwaves are coupled into the element at a frequency near a resonance, and a modulating signal is applied so as to modulate the response of the element. Measurements of both the mean response and the modulation of the response enable the dielectric constant and dielectric loss of the material to be determined. Modulation may be applied to the frequency of the microwaves, or to the electrical parameters of the element.

Abstract: Method and apparatus for obtaining an enhanced clearer measurement signal with improved fringe contrast from a laser interferometer. The interferometer sends a laser beam (12) through atmospheric air to a polarizing or nonpolarizing beamsplitter (13) that sends one laser beam portion (14,16) to a fixed reference retroreflector (15) and another portion (19,21) to a movable measurement retroreflector (20). Both beams, upon retroreflection go back to the beamsplitter and are recombined to produce a combined beam (22) that is then sent to an aperture (30) such that only a small selected portion of that combined beam passes through the aperture, attenuating the energy of the combined beam but increasing its fringe contrast. This portion is sent to a detector (32) and is subsequently amplified by a high-gain amplifier.

Abstract: A method and apparatus is disclosed for the safe removal of asbestos-containing materials present in buildings in the form of ceiling or wall panels and the like. The apparatus includes a panel-sized containment bin (10) which includes rotary saws (12) that extend outward therefrom to cut loose the asbestos-containing materials. A protective surfactant is first applied to the material to be removed, and the material is then sawed into conveniently sized panels using slow-speed cutting heads and both primary and secondary negative air pressure systems so as to capture within the containment bin (10) any asbestos fibers that become airborne. An encapsulant is also applied to the materials being removed immediately after cutting. The invention may be used for both vertical or horizontal panel installations. The apparatus is mobile and self-propelled, and may be remotely operated to give additional operator safety. The invention when in use has limited the production of residual airborne asbestos fibers to an average of 0.0032 fibers/cc, of fibers over 5 microns long and having an aspect ratio of 3:1, the range of such fiber counts over 15 measurements being 0.0024-0.0047 fibers/cc with a standard deviation of 0.00096.

Abstract: A switched reluctance motor has its stator poles divided into at least three phases, each phase having its own independently switchable phase windings wound around the corresponding stator poles. First switch elements control application of power to the windings of the first phase, second switch elements control application of power to the windings of the second phase, and third switch elements control application of power to the windings of the third phase. For low speed operation of the motor, the switch elements for each phase are controlled to apply power to its respective phase windings from a selected turn-on angle to a selected turn-off angle. The maximum difference in low speed operation between the turn-on angle and the turn-off angle for each phase is no greater than the angle sub­tended by adjacent stator poles as measured from the geometric center of the stator. For high speed operation, only the windings of the first phase are energized, and the difference between the turn-on angle and the turn-­off angle for the first phase windings is greater than the angle subtended by adjacent stator poles.
