Patent EP-0383062-A2 (EP)
Inventor: RENZ WALTER DIPL-ING FH
IPC: E05D15/52
Filed: 1990-01-24
Abstract: In a two-wing window with two wings (3) and (4) arranged one above the other, an especially compact furniture design in the region of the tilting axis of the upper wing and of the associated articulation of a setting-out arm of the lower turn-and-tilt wing is obtained if these two bearings are united to form a combined tilt and scissor bearing with a common basic body (9). In the vertical direction, that is to say in the direction of the axis of rotation of the lower wing or of the two wings, a short constructional length is obtained, with the result that the two wings can be brought near to one another and it is possible to use a narrow profile for the abutment (2) between the two wings. In order, despite this short constructional length, to make it possible to reach the fastening screws (24, 25) easily even when the fastening plate (17) of the basic body (9) is narrow, but on the other hand to avoid having to incur disadvantages in the hanging and removal of the wing (3), the bearing journal (16) of the tilt bearing located on the same side as the axis of rotation can pivot beyond the known inclined position of such bearings. This is possible because the bearing journal (16), in its inclined position conventionally constituting the maximum pivoted position, bears preferably with the edge (18) of its bearing lug (19) against a stop (20) of the basic body (9), and this stop can be overcome resiliently. <IMAGE>

Abstract: An amplifier circuit includes a negative feedback connected amplifier (A) and a series circuit comprising a capacitor (C1), one end of which is connected to an output terminal (V1) of the amplifier (A), and a resistor (R2), one end of which is connectable to a reference potential (Vcc/2). A comparator (CP) is provided which has first and second inputs and one output. The first input is connected to a junction (V2) between the capacitor (C1) and the resistor (R2), the second input is connected to an output (V1) of the amplifier, and the output (VCP) of the comparator (CP) is connected to one input of the amplifier (A). The comparator (CP) does not react to an AC signal of a specific frequency band, but operates to set the output offset voltage only to one fractional part of the transition gain, and therefore operates to accomplish offset compensation without using a large capacitor.

Abstract: Elevator door chain contacts are isolated from the safety chain in a separate circuit, thus enabling the use of a separate door chain coil for independently checking the status of the door chain itself and for enabling the remainder of the safety chain. The status of the door chain itself may be checked to make sure the doors are all closed when they should be. If it is determined the doors are not all shut, the car door may be cycled open and shut in an attempt to correct a possible problem at the landing. The individual hoistway door contacts in the door chain may be checked, one at a time, while the car doors are fully opened at each particular floor to make sure that the door chain is not being incorrectly shorted, i.e., to make sure the hoistway door switch contact at the particular floor is opening when it should. A checking contact may be wired into the door chain and used to selectively open circuit the door chain to ensure that the door chain coil is not directly shorted to the power supply. Since the door chain contacts are isolated from the safety chain in a separate circuit, the length of wire and the number of connections between the AC supply and the object relay coil can be reduced in both the door chain itself and the remaining part of the safety chain.

Abstract: A method of clustering nodes in a distributed computer network to reduce the overall processing and storage requirements at the network nodes. The network is parti­tioned into subsets (25, 75) with one node (10, 100) in each cluster designated as the cluster control point. The cluster control point represents the cluster as a single node (25 or 75) to the external part of the network. It maintains an internal topology database of network re­sources within the cluster and an external topology data­base of network resources outside the cluster for use in determining routes for sessions throughout the distributed network. The cluster control point (10, 100) is the focal point in assisting the external part of the network to locate network resources internal to the cluster and in assisting the internal nodes to locate network resources external to the cluster. Internal resources found as a result of a search are maintained in an internal directory cache at the cluster control point, and external resources found are maintained in an external directory cache.

Abstract: This arrangement enables high-resolution screens (HB) with a single pixel selection to be used and avoids the derivation of a check code from the serial picture data stream which is problematic at very high frame buffer read-out frequencies. To form the check code, the picture data, which are entered into the frame refresh buffer (BW1), are entered in parallel to another similar buffer (BW2) which is not followed by a screen and are immediately subsequently read out of the further buffer to a check code generator (P). A check code generated by the check code generator is compared with a previously stored reference code and checked for correspondence in a control processor (SR) requesting the signalling frame display. An error is indicated if there is no correspondence. <IMAGE>

IPC: G01S17/87
Filed: 1991-02-08
Abstract: A three-dimensional contour measuring apparatus having a pair of lasers spaced at a given constant interval. In order to determine degrees of deformation relative to the original contour requiring no base on which a traffic-damaged car is put in determining degrees of deformation, it has associated stepmotors to permit each laser to throw its beam of light towards a desired direction and means to control the elevation of these lasers. A triangle formed by the distance (base) between the opposite lasers and two distances (sides) extending from either laser to a selected point on an object is used to determine the coordinates of the selected point according to the triangulation.

Abstract: An in-circuit emulator comprising a microprocessor having an input terminal for selecting whether or not the data obtained by accessing an external address should be registered in the cache memory, a register for storing an address for discontinuing the execution of the microprocessor, and a comparator for comparing an address outputted from the microprocessor with the address stored in the register. When the result of comparison is indicative of coincidence, the comparator outputs a coincidence output signal to the above mentioned terminal of the microprocessor, so that the data is inhibited from being registered into the cache memory. Therefore, an external access is performed for the address discontinuing the execution, and accordingly, a break address can be detected by a device external to the microprocessor.
