Title: Bushing, especially for high voltages
Inventor: RAUPACH FRIEDRICH DR ING
IPC: H01B17/36
Filed: 1986-05-14
Abstract: A bushing, especially for high voltages, for connecting an electrical apparatus (which is insulated by an inert gas at high pressure), such as a transformer, inductor coil, measurement transformer, capacitor or the like, to a connecting point which is located in the atmospheric air is intended to be improved such that an arrangement is provided within an insulating collar, which arrangement reliably prevents the high gas pressure on the apparatus side acting on the sensitive insulating collar while occupying a small amount of space, even when a plurality of electrodes are used. This is achieved in that insulating perforated discs (19) are arranged between the flange, which is at earth potential, and the electrode or electrodes (12, 13) and the high-voltage conductor, which perforated discs (19) separate the high gas pressure on the apparatus side from the low gas pressure in the interior of the insulating collar (4) and mutually seal them, and hold the electrodes (12, 13) at a predetermined radial separation (Figure 2).

Inventor: HINSKEN GERHARD PROF DR
IPC: G05B19/05
Filed: 1987-08-27
Abstract: In a stored programme control, interconnections of subsets of input signals can be measured in parallel with the interconnections of all input signals within a binary value processing programme and used for further processing. In parallel with the programmable processing of the bit processor (BP), an interconnection status (VKS(n)) is automatically constituted for each AND-BRACKET-ON control statement and stored in a nesting store (ST). The interconnection status (VKS(n)) is obtained by AND-interconnection from the previous corresponding interconnection status (VKS(n-1)) and from the corresponding interconnection result (VKE) present in the bit processor (BP). By means of control statements ''SZM: Set intermediate marker'' and ''L2M: Load intermediate marker'', an intermediate marker result (ZM) corresponding to the interconnection of subsets of input signals can be stored at any desired point in the programme in an intermediate marker store (ZMS) or read therefrom for subsequent processing.

Title: Electrical switching or distributer installation which is encapsulated in a pressure-tight manner and has a bursting protection device
Inventor: SCHMITT HANS-JUERGEN
IPC: H02B13/025
Filed: 1987-12-22
Abstract: An electrical switching or distributor installation which is metal-encapsulated in a pressure-tight manner or is provided with an outer metal layer, preferably for the medium-voltage range, contains a bursting protection device, which fractures if a maximum possible overpressure is exceeded, in the form of a membrane-like bursting disc. This bursting protection device (11) is distinguished by the fact that a sealing element (at 19) is used which is constructed like a disc, externally completely covers the associated encapsulation opening, seals said opening by means of a pressed-on flange ring (12) and at the same time forms the bursting disc. In addition, a metallic encapsulation plate (13) is inserted and held between the outer surface of the sealing element which forms the bursting disc and the flange ring (12) arranged above it, which encapsulation plate (13) is provided inside the extent of its surface with a split (16), which is largely but not completely circumferential, is at least approximately the same as the encapsulation opening in shape and dimensions, and forms a flap (19) which can spring out or bend out. In consequence, virtually continuous surface earthing of the encapsulation is ensured without adversely affecting the functionality of the bursting protection device. In addition, the encapsulation plate offers protection against the bursting protection device being damaged from the outside. <IMAGE>

Title: Pressing-on station for foil blanks laid around the head of bottles in a labelling machine
Inventor: ZODROW RUDOLF
IPC: B65C9/36
Filed: 1987-12-24
Abstract: To improve the covering of bottles with foil, provision is made for the bottles 1, provided with foil blanks 36 in a labelling machine having a foil-covering station, to be fed to a transport table which is located downstream of the labelling station and on which the bottles are moved in a manner clamped fixedly in terms of rotation axially, between a rotary plate 19 and a smoothing and pressing-on element 20, past brushes 34a, 34b arranged on both sides of the transport path and acting on the foil blanks. The pressing-on and smoothing element 20, in a first working position, presses on the foil blank on the end face and, in the head region, on the sides. In a second higher working position, it largely frees the head region of the bottle, so that the brushes 34a, 34b can also press on the foil blank in the head region. So that this pressing-on can take place over the entire circumference, the bottles are rotated by the rotary plate in the region of the fixedly arranged brushes 34a, 34b. <IMAGE>

Title: Amplifier for light with equal amplitudes of the output pulses
Inventor: MOZER ALBRECHT DR RER NAT
IPC: H04B10/299
Filed: 1988-03-17
Abstract: The repeaters used in optical communication are intended, inter alia, to convert a series of optical input pulses of variable amplitude into a series of output pulses of equal but amplified amplitude. The device proposed here consists of an electrical parallel circuit of a controlling element 10, for example a photoconductor, a photodiode or a photodiode connected to active electronic components, and of an optical amplifier 11 which has a constant current IE flowing through them. The current flowing through the controlling element is, in the simplest case, proportional to the intensity of the input pulses, and the amplification of the optical amplifier is proportional to the current which flows through it. In this way, a current-controlled amplification of the optical amplifier is achieved, at the output of which there then appears a series of pulses of equal intensity. <IMAGE>
