Abstract: 2.1 Load interruptor switch installations are used virtually universally in medium-voltage distribution networks. In this case, compressed-gas-insulated installations are preferred. However, because of complicated busbar arrangements, it is not possible to house such switch installations in a very small space. 2.2 In order to achieve this object, it is proposed that a plurality of load interruptor switches be arranged in a gas tank (1) such that the switching blade (2) of one phase of the "on" position makes contact with a common contact piece (3) which is constructed functionally as a busbar. In this case, the contact piece (3) is equipped with extinguishing devices (6) for the switching blade (2). Furthermore, the earthing devices are constructed as earthing contacts (7) connected to a switch shaft (8). 2.3 Such switch installations can preferably be used in compact network stations in a very small space. <IMAGE>

Abstract: Superconducting element, in particular for a detector of electromagnetic radiation in the IR range up to decimetre waves having the following structure: superconductor (S1), barrier (B), superconductor (S2), insulator (I) and superconductor (S3). The superconductor (S1) is transparent to the electromagnetic radiation. This affects the signal current taken off between S1 and S2 in the barrier (B). The frequencies for which the sensor is to be most sensitive can be set by altering the working voltage between S1 and S2 and passing a control current for the energy gap through the superconductor (S3). <IMAGE>

Abstract: A photomask which is treated so that, even if the photomask is stained with a trace amount of contaminative particles during washing, water and a low-volatile component are prevented from adhering to such contaminative particles during the storage of the photomask, thereby preventing the photomask from becoming stained with passage of time. Also disclosed is a method of producing the photomask. The photomask is subjected to a hydrophobic treatment by a chemical reaction with OH groups in the mask surface. More specifically, the photomask has on the surface thereof a trimethylsilyl film which is formed from OH groups by the hydrophobic treatment. According to the treating method, the photomask which is to be subjected to a hydrophobic treatment is exposed to a gas atmosphere containing 1,1,1,3,3,3-hexamethyldisilazane, or it is coated with a treating solution containing 1,1,1,3,3,3-hexamethyldisilazane. Since the mask surface is subjected to a hydrophobic treatment by a chemical reaction with OH groups, even if contaminative particles attach to the photomask in a trace amount during washing, no water or low-volatile component will adhere to such contaminative particles during storage, so that the photomask is prevented from becoming stained with passage of time.

The apparatus includes a laser printer (5) and folding sealing apparatus (6) controlled by a data processor. The folder sealer apparatus (6) combines sheets printed by the laser printer (5) with pre-printed sheets and envelope forms, which also may be printed by the laser printer (5) or may be windowed envelopes, folds the sheets as necessary and folds and seals the envelope form about the folded sheets to produce a mail piece. A user inputs a configuration for the mail piece which is translated by the data processor into a data structure and transmitted to the controller of the folder sealer apparatus (6). The controller controls devices comprised in the laser printer (5) and the folder sealer (6) by executing state routines in accordance with the data structure to produce the mail piece in the defined configuration. Concurrently the data processor transmits text from an output file to the laser printer (5) for printing on printed sheets and envelope forms. The data processor also controls the laser printer (5) to print an address for the mail piece either on an envelope form or on a printed sheet in a position where it will be visible through the envelope. Thus the apparatus is controlled to process an output file stored in the data processor into a mail run having a selected configuration. A mechanism and method for accumulating and folding sheets is also disclosed.

Abstract: A safe-arm or quick arm system for a perforating gun includes a body containing a detonator and an adapter head containing an electrical plug and a detonating cord shell, the body and associated detonator being rotatable relative to the adapter head and associated detonating cord shell. Upon rotation of the body relative to the adapter head, the detonator moves from a start position to a transport position. In this position, the plug is not electrically connected to the detonator and the leads connected to the detonator are short circuited. The detonator is not adapted to receive electrical power. Upon further rotation of the body relative to the adapter head, the detonator moves from the transport position to an electrical contact position. In this position, the plug is electrically connected to the detonator but the detonator is not aligned with the detonating cord shell. Upon further rotation of the body relative to the adapter head, the detonator moves from the electrical contact position to the armed position. In this position, the plug is electrically connected to the detonator and the detonator is aligned with the detonating cord shell.

Abstract: A transmit-receive station connected to a high speed ring bus carrying data signals that may be received from and sent to each station on the ring bus has two sources of transmit clocking signals. One source is based on the frequency and phase of data signals received on the ring bus from another station and the other source is a local crystal oscillator having essentially the same frequency as the first source but in an indeterminate phase. When changing the source of clocking signals for transmission of data originating at the station, bit slippage may be minimized by providing the local oscillator output signal in four phases and using the phase most nearly aligned with the other clocking signal when the change is made. 
     Control of access to transmit by a station employs a token having a message field of seven bits and a access control bit. Each message frame ready for transmission is assigned a priority number which is used with the token to cause the data message frames at different stations to be transmitted in a sequence based on their respective priority numbers.

Abstract: A hybrid switching matrix module (K) with a synchronous switching element (CS) and an asynchronous switching element (PS) is specified which makes it possible to utilise the transmission capacity of a packet switch optimally even if, in addition to an occurrence of packets to be switched asynchronously, which takes up the major proportion of the transmission capacity, a few packets are to be switched synchronously and the proportion of these packets takes up a transmission capacity of less than 2 Mbit/s. In the switching matrix module, shorter subframes with subpackets are formed from original frames, by which, as soon as a packet to be switched synchronously is detected, predetermined time slots are reserved for the duration of this packet for information from this packet and are switched through via the synchronous switching element. To signal the synchronous switching-through, a special control line (SL) is needed in each case between the input demultiplexer (DM) and synchronous switching element (CS) and between the synchronous switching element and the output multiplexer (M). <IMAGE>
