At each end of the train and A.A.R.

Abstract: A tarpaulin or other similar protective cover of flexible sheet material is adapted to be tied down securely with the aid of a single tie-down line extending around its periphery. The periphery is edge-finished with a continuous hollow conduit laterally fluted at equally spaced intervals with identical semi-circular cut-outs deep into the hollow conduit. Each cut-out defines a hole in the conduit wall which, in use of the tarpaulin with a tie-down line loosely contained in, and longer than, the conduit, permits a length portion of the line to be pulled outwardly from the conduit in a looped configuration for anchoring attachment to a respective tie-down device. Tearing of the tarpaulin by anchoring forces exerted thereon by way of the single tie-down line is effectively resisted, notwithstanding the absence of grommets or other relatively expensive reinforcement measures.

The opposite end includes a toothed scale for setting counterweights along the arm according to a set of predetermined locations which carry indicia related to the dimensions of the flask to be centrifuged. An overrunning clutch is included in the base of the centrifuge to engage the arm during wind-up and acceleration. The arm runs free for rotation during deceleration. Swing of the flask is limited to facilitate acceleration of the motor.

Abstract: A method and apparatus for cleaning and filtering contaminants from the refrigerant in a refrigeration system does not permit any gaseous refrigerant to escape to the atmosphere during repair of the system. A tank containing a disc of filter material has piercing valves connected to an inlet and an outlet. The tank and filter are connected to the contaminated system by the piercing valves, the contaminated refrigerant passes through the filter and is retained in the tank. Once the system is repaired, the refrigerant passes from the tank and filter into the system, but the tank and filter remain connected thereto while the system is operated. The tank and filter are removed after a time sufficient to clean the refrigerant.

Abstract: Apparatus for burning material such as fuel, waste material and the like, which when burned produces gases within which pollutants are entrained and for cleaning the gases. The apparatus comprises an incinerator or a furnace having a combustion chamber in which the material is burned and in which tubes, preferably apertured, extend through the burning coke to which solid fuels are reduced and through the flames of an oil burner gun, for example within the confines of the combustion chamber which in such an instance is also a refractory chamber, act to conduct the polluted gases of combustion from the burning material through the same burning material where they are super heated and cleaned.

Abstract: The invention relates to a bearing housing for driven and air-suspended spinning rings on ring-spinning and ring-twisting machines, whereby a tape drive with tensioning pulleys is provided for the spinning rings. The object of the invention is to decrease the amount of material and working time when the bearing housings are attached (applied) to the ring rail and to shorten the time required for the adjustment of the spinning rings and of the tensioning pulleys. The technical task which is being solved by the invention is constituted by the fact that the number of fastening elements needed for the attachment of the bearing housings to the ring rail is decreased and that the spinning rings are not individually adjusted and that the tensioning pulleys are not adjusted at all. According to the invention, this is accomplished by having at least two spinning rings (2;3) and one tensioning pulley (5) arranged on one bearing housing (1).

Abstract: A modular electronic system is constructed by the interconnection of modules containing individual circuits. Each module includes a set of contact pads disposed at sites which are predesignated for the interconnection of corresponding terminals in the various circuits, which terminals are to be interconnected upon assembly of the system. The contact pads are disposed on the exterior surfaces of the modules and in a predetermined arrangement so that all electric connections can be accomplished unambiguously and only upon proper alignment of the modules. Activation of individual circuits may be delayed until completion of assembly by use of a sensing circuit in each module which determines that assembly has been completed or, alternatively, a displaceable connecting plate mounted on a resilient surface may be employed for springing out of connection when the modules are displaced from each other and making connection for activation of the circuits when the modules are contiguous to each other.

Abstract: An improvement in linear rolling bearing assemblies having cylindrical outer sleeves with a central bore and a cage within such bore having outwardly extending projections which define a plurality of continuous ball circulation paths, each comprised of a longitudinal load channel and an adjacent longitudinal return channel. The improvement consists of a unitary cylindrical outer sleeve having longitudinal load-carrying lands and accompanying return channel grooves, the load-carrying lands straddled by the outwardly extending projections of the cage in such a way that restricted rotation of the cage relative to the sleeve is permitted. The return channel groove is formed in the bore of the outer housing by a substantially horizontal deformation from the load-carrying land which deformation is blended with a ball-conforming shape whereby guidance is provided the balls through the return channel.

Abstract: A system and method for amplitude modulating a carrier signal with an audio or other information input signal relies on multivibrators and comparators initiating a logic controlled processing technique for providing two sinusoids, each a fundamental frequency waveform, the two having a mutual phase relationship defined by intermediate processing steps such that they differ in phase from 0 to 180 electrical degrees. The comparators output first resultant pulses when the carrier signal is greater than the amplitude of the audio or other information input signal. The first resultant pulses are input to a logic processing network to trigger multivibrators which output overlapping 180.degree. wide pulses, respective phase shifted resultant signal waveforms being formed from the respective comparator outputs.

Abstract: Electron-beam (EB) coating of broad strips with improved film quality, and without undue scattering and deflection of the electron beam at long beam paths is accomplished with a shielding mantle, placed between the EB gun and the evaporation crucible, providing vacuum-tight shielding of the beam path from the coating chamber.

Abstract: The present invention is a coating apparatus for temperature-sensitive broad strips or similar substrates. To obtain a high quality of coating, it is necessary to minimize the path of the electron beam (EB) through the vapor cloud, and to keep away backscattered electrons from the evaporating material. According to the invention, this problem is solved by assembling a sector field with a vertical field direction at the deflection system connected with the EB gun, which is followed by a deflection field with a horizontal field direction. The divergent electron beam is guided in lines to the evaporating material by the geometry of the fields.

Abstract: A security fence system employs a plurality of very thin, high tensile strength, highly stressed wires arranged relatively close together and between each of which is connected an electrical resistance. A voltage source causes a current to flow through the series-connected wires and resistors. An annealed segment can be formed in each high tensile strength wire and located between the points where each wire is attached to the fence posts, to make stretching of the wires without breaking them impossible. A sensing circuit is connected to the fence and includes voltage comparators and potentiometers for providing adjustable triggering levels. The comparators detect when the current flowing in the fence is altered and trigger an alarm if any of the wires are broken, or if any of the wires contact one another. The alarm can be turned off only by normalizing the fence and actuating a reset switch.

Abstract: A hearing aid comprising a microphone whose output signal is split by high and low pass filters and supplied to two channels. Each channel includes a variable gain circuit the outputs of which are mixed and supplied to an earphone. The turnover frequencies of the filters are such that one channel limits the dynamic range of vowels whereas the other channel limits the dynamic range of consonents, thus preventing interaction and masking of consonants by preceding vowels. The intelligibility of speech is thus improved.

Abstract: A transparent cover for a solar panel has a number of uniform undulations or ridges across its surface. The cover is formed of a plurality of lens elements arranged over the entire surface of the cover and at specific angles along the ridges. The lenses focus and intensify the incident solar radiation onto the thermal collector elements of the panel.

Abstract: Material useful in bullet-proof clothing is formed from a number of laminates arranged one on top of another. The laminates are preferably formed of a substrate coated with a crushed thermosettable foam that is, in turn, covered with a surface film, which may be an acrylic polymer. The films should form the outermost layers of the composite material which, together with the foam layer, prevent degradation of the substrate, which is typically formed of fabric woven from Kevlar.
