Title: Stairway handrail
IPC: E04F11/18
Filed: 1987-10-10
Abstract: The stairway handrail consists of straight handrail sections (22.2,22.3), the end faces (40.2,40.3) of which are cut off vertically. Between them, corner pieces (25) are provided. The latter have, in their connection side faces, indentations (30.1,30.2) with a width corresponding to the thickness of the handrail sections. The indentations do not reach as far as the top cover face (31). The side walls (45) of the indentations (30) cover the ends of the handrail sections and thus conceal inaccuracies and imperfections produced when cutting off the end faces (40).

Title: A gas circulator for a nuclear reactor and a method for use thereof
IPC: H02K5/12
Filed: 1987-01-23
Abstract: An improved gas circulator for a gas-cooled nuclear reac­
tor system is disclosed which includes a stator, a rotor having 
a rotor shaft, and an impeller attached to one end thereof. A 
radial active magnetic bearing and a radial backup bearing 
are positioned proximate each end of the rotor shaft. An axial 
active magnetic bearing is also located between the ends of 
the rotor shaft, as is an axial backup bearing, with two of the 
backup bearings enclosed within a sealed chamber that may 
contain a lubricant, for example, a solid lubricant or a liquid 
lubricant. Preferably, the gas circulator is installed in a nuc­
lear reactor system with the rotor shaft in a substantially ver­
tical orientation and the sealed chamber near the bottom of 
the rotor shaft. The lower radial backup bearing and the axial 
backup bearing are advantageously located within the sealed 
chamber. The lower radial backup bearing and the axial 
backup bearing may be spaced apart sufficiently to permit the 
lower radial backup bearing to provide substantially all radial 
support for the rotor when the radial active magnetic 
bearings are deenergized.

IPC: E21B21/14
Filed: 1987-06-11
Abstract: a method of removing at least a substantial 
proportion of fluid left in a generally horizontal 
section of a pipeline, by injecting into the pipeline 
a pressurized, high expansion foam and advancing the 
foam through the pipeline section in contact with 
a layer of the fluid left therein to displace the 
layer towards a remote end of the pipeline by frictional 
pick-up of the layer by the foam and to effect mass 
transfer of a foaming agent from the foam to the fluid, 
followed by passing into the pipeline a pressurized 
gas to create turbulence in fluid left in the pipeline 
causing foaming of the fluid and to displace a substantial 
proportion of the foam left within the pipeline. 
At least some of the bulk of the fluid in the pipeline 
may be displaced by injecting the foam so as to establish 
a transverse foam/fluid interface which is advanced 
through the pipeline at or above a minimum velocity 
required to maintain said interface leaving a residual 
amount of fluid which is treated as aforesaid. The 
method may include the further subsequent step of 
injecting into the pipeline a pressurized foam containing 
a treatment agent to displace residual foam left in 
the pipeline, and then allowing the foam to decompose 
in the pipeline to deposit the treatment agent within 
the pipeline either on the pipewall or in solution 
with any liquids remaining therein.

Title: Speed control for orbital shaker with reversing mode
IPC: B01F15/00
Filed: 1988-06-13
Abstract: An orbital shaker apparatus which has a tray for cyclic motion is flexibly suspended from a frame which is flexibly suspended from a plurality of stationary supports. The flexible suspension constrains the tray to move only translationally along one axis with respect to the frame and constrains the frame to move only translationally along one axis perpendicular to the tray movement axis. A single chip microprocessor is used to scan, input store, display and control the speed, duration and control functions for the orbital motion. Embodied in the software of the microprocessor is a real-time closed loop speed control which monitors the actual speed of the orbital motion thru an interrupt facility by calculating the duration of pulses received from an optoelectric sensor. The measured pulse duration is digitally compared to the desired duration and a digital control signal is provided to drive a DC motor which is directly coupled to the drive shaft which imparts the motion. A set speed mode and a reversing mode are selectable by an operator to provide different means for agitation.

Title: Section insulator in traction lines
IPC: B60M1/18
Filed: 1989-05-12
Abstract: In electrical tracks with overhead wire operation, the traction line is divided up into individual traction line sections by section insulators. So that they can be passed over, the section insulators are provided with contact skids. If there is different electrical potential between two traction line sections, the current collector discharges a power arc which destroys the section insulator. Attempts have been made to extinguish the arc by bypassing via a switch. The drive coil of the switch is connected between an auxiliary electrode which extends into the second traction line section and is insulated with respect to it, and the second traction line section, so that the arc current flows through the drive coil. This arc current fluctuates in such a way that actuation of the switch is not ensured so that damage nevertheless occurs. The intention is now to ensure that the switch switches reliably and namely with a specific delay (e.g. 80 ms) and opens with a considerably longer fall-delay time of e.g. 200 ms. According to the invention, the drive coil of the switch is connected to the auxiliary electrode and the second traction line section directly via a saturation converter, the secondary voltage of which, connected to the drive coil, is constant and independent of the level of the arc current flowing in the primary winding. A rectifier for rectifying the output alternating voltage can be connected to the secondary winding of the saturation current converter and the drive coil of the switch can be constructed as a direct current drive coil.   Section insulators are used for the electrical isolation of a first and of a second section of an electrical traction line for traction vehicles having an insulating body which electrically isolates the sections. <IMAGE>
