Title: Method for load distribution among the processors of a high-availability multiprocessor-type common control unit of a switching system
Inventor: CLARK MARK
IPC: H04Q3/545
Filed: 1986-08-29
Abstract: In this method, a number of IO processors (IOP) represent the interface between the common control unit and the peripheral units (MBG), and a number of central processors (BP, CP), which are used for processing switching tasks, and a central memory (CMY), which can be accessed by the central processors (BP, CP) via a bus system (B:CMY0, B:CMY1), are connected in parallel to the central bus system (B:CMY0). Information on all new switching tasks occurring is stored, i.e. written in, by at least one of the IO processors (IOP) in a central logging device (for example in B:CMY or contained in CMY). All operable central processors (BP, CP) becoming available in each case report by themselves in that they (for example CPx) fetch or attempt to fetch information on a new switching task present from the logging device after which, after such information has been fetched, this information is deleted in the logging device. <IMAGE>

Patent DE-3641441-A1 (DE)
Title: Device and method for testing controllable gate turn-off semiconductors for faults
Inventor: MCMURRAY WILLIAM
IPC: G01R31/26
Filed: 1986-12-04
Abstract: A fault in a gate turn-off thyristor (GTO) or a bipolar transistor is determined within the circuit, before an anode-cathode (collector-emitter) voltage is applied, by generating a gate pulse and monitoring the resultant gate (base) current. A fault in a gate turn-off thyristor almost always results in a short circuit between the gate-cathode terminals and between the anode-cathode terminals. The gate terminal can be interrupted in the case of other faults (idling state). The base-emitter path of a bipolar device can become faulty in a similar manner. Thus, the gate current which results from a gate pulse becomes abnormally large when the gate-cathode (base-emitter) terminals are short-circuited or the current is zero for an interrupted circuit or for a gate driver fault.
Patent DE-3641992-A1 (DE)
Title: Method for automatic exposure of X-ray photographs, especially for mammography
Inventor: KRATZAT MANFRED DR
IPC: H05G1/44
Filed: 1986-12-09
Abstract: The invention relates to a method, especially for mammography, as well as to an arrangement for carrying out the method, in the case of which the dose is measured behind an image recording device, for the purpose of automatic exposure. The dose which is measured in this case depends greatly on the attenuation of the radiation by the object, and, according to the invention, a test photograph is therefore carried out first using a considerably higher tube voltage and defined photograph parameters. The disconnection dose for the automatic exposure device is determined from the dose measured at the end of the test photograph, that is to say the subsequent X-ray photograph, which is carried out at a considerably lower tube voltage, is disconnected when this disconnection dose is reached during the X-ray photograph. <IMAGE>

Title: Device with a generator and an electrode for high-frequency cutting and/or coagulating or for laser applications
Inventor: GMINDER FRANK
IPC: A61B18/00
Filed: 1986-12-10
Abstract: The invention relates to a device with a generator and an electrode for high-frequency cutting and/or coagulating or for laser applications. In order to separate the application electrode from the conductive surface blood in an insulating manner the invention proposes that the electrode be surrounded by at least one jacket for guiding a non-conductive, pressurized gas or a non-conductive liquid. This results in a clearing effect on by-passes, which as a rule are disadvantageous, in the application area. Effective insulation of the electrode is thereby achieved for the first time.

Patent DE-3802163-A1 (DE)
Title: Special-mattress sections
Inventor: BRAUN JEAN
IPC: A47C27/06
Filed: 1988-01-26
Abstract: Mattresses or pads, the contents of which, including those comprising air-filled spring elements, for the purpose of frequent cleaning or disinfection, similar to when dealing with the changing of bed linen, are produced disassembled and so that they can be put together again. Mattress fillings, normally referred to as spring interiors or foam cores, in compact units differ from this invention in particular in that the spring elements are composed of a plurality of individual parts, each part having its own variable degrees of flexibility and being able to be cleaned and even disinfected for hygienic reasons. Since the invention also provides for loose, cleanable covers or mats as coverings of such novel spring interiors, measures can be more easily and effectively taken against transmissions of infections from patient to patient or from one guest to another, in tourism or among household members. In addition, it is possible to adapt or alter the degrees of hardness or degrees of softness of a bed or seating arrangement to individual personal requirements by a greater or lesser number of air supplies in each case.

Title: Easy-sliding, two-rein ring spindle lunge with intermediate rope piece for training/exercising of riding horses
Inventor: ELFERING BERNHARD
IPC: A01K15/02
Filed: 1988-06-18
Abstract: Easy-sliding two-rein ring spindle lunge with intermediate rope piece, consisting of a lunge harness (A) with fastening straps (A1, A2, A3), and two lunge reins, for training and exercising of riding horses. Previous lunge bridles prevented an optimum gymnastic exercising of the horse as they made possible neither a flexible action on the holding of the head in an upright position (= neck bending) nor a greater freedom of the neck of the horse without interrupting the movement processes or falsifying a correct rein action. Bridling and mode of action of the lunge (drawing): the lunge reins are fastened on the girth on both sides of the horse (D1), run as intermediate rope pieces (D2) through the snaffle rings, then through the lunge guide rings (B1, B2) and subsequently into the hand of the lunge operator (D3). The spindles (C1, C2) can be fastened as required on the intermediate rope pieces. In interaction with the lunge guide rings, they thus limit the holding of the head in an upright position, whereas the freedom of the neck of the horse is preserved. The sliding rings on the lunge guide rings (not shown in the drawing) reduce friction and resistance on the lunge reins running through and thus considerably increase the capacity for sensitivity in the mouth of the horse. The slip gaps on the lunge guide rings (SL) make possible rapid hinge refastening on changing hands by simple rehanging. <IMAGE>
