Abstract: A flashlight has front and rear interconnected housing portions which define an interior waterproof chamber. The waterproof chamber carries an illumination source, an electronic drive for the illumination source and a power source. A switch system includes an electronic switch component for switching the relatively high current required for the electronic drive while a mechanical switch (e.g. a magnetic reed switch) activates the electronic switch component, therefore maintaining integrity of the waterproof seal about the chamber. A commutator assembly is provided to maintain electrical contact between the switch and other components. The power supply may be in the form of a plurality of battery stacks batteries aligned in the housing in a manner to provide a compact unit, while electrical components may be mounted to circuit boards positioned transversely to the length of the flashlight.

Abstract: A stencil screen platemaking apparatus for a heat-sensitive platemaking method, having a thermal head retaining frame to which a thermal head is attached arranged to oppose a platen roller retaining frame having a platen roller attached thereto, and a stepping motor, in a manner permitting contact and separation between the thermal head and the platen roller. In the separated state of the thermal head and the platen roller, an art work material is arranged between both retaining frames, so that the screen is pinched between the thermal head and the platen roller. Then, the platen roller is driven and revolved so that platemaking is performed in a state that the thermal head is maintained at a fixed position and that the art work material is moved.

Abstract: An escalator or moving walkway has a step or plate belt with motor-driven steps or plates and free-running steps or plates. A drive frame connected with a frame serves as support for a drive unit of a motor-driven step or plate. The drive unit includes a motor, a transmission and a brake. A friction wheel, which transmits drive power to a travel track, is arranged at the transmission output, while a counter-pressure roller arranged in a fixed position on the drive frame laterally guides the step.

Abstract: Apparatus for converting a flexible liner 2 including a layer 3 of composite material comprising thermoplastics material and reinforcing fibres, into a structural member within a duct 1, has a front portion 6 for insertion in the liner 2, a central portion 7 for heating one side of the layer 3 and a rear portion 20 which forces the heated layer 3 against the duct 1 for consolidation and cooling under pressure. The central portion 7 has heating means 8 producing hot gas which is forced under pressure through the layer 3 of composite material to heat the layer 3, and provides an air gap 14 on the opposite side of the layer 3 while heating takes place. This ensures uniform heating of the layer 3, to melt the thermoplastics material which then mixes intimately with the reinforcing fibres, and is consolidated and cooled to form the structural member.

Abstract: A bolted fastener for joining components, such as a bracket fastened to a crosspiece, includes a bolt, a nut and an eccentric. A square neck of a bolt fits into an oblong hole in a component and prevents the bolt from turning. The diameter of the eccentric that serves as a wedging means fits into the slightly larger diameter of the receptacle hole, allowing the eccentric to fit into the receptacle hole. When the nut is screwed on the bolt, the eccentric rotates about the bolt and, on account of its eccentricity, wedges itself within the receptacle hole. The wedged eccentric prevents accidental loosening or accidental unscrewing of the nut.

Abstract: A wheel for driving a flexible handrail of an escalator or moving walk. The wheel has a power transmission element that can be turned about an axis of rotation and that has, on its circumference a contact surface through which an outwardly acting radial force can be exerted. The wheel also has two base sheaves that are arranged coaxially to the power transmission element. Each base sheave has a plurality of slits that are arranged in the outer edge area of the base sheave and extend toward the axis of rotation. The slits of one base sheave form, with the slits of the other base sheave, slit pairs. The wheel has a circumferential cover with an inside surface against which the contact surface of the power transmission element rests. A plurality of pins is arranged in the circumferential cover, each pin engaging a separate respective slit pair.

Abstract: A personal support device having particular utility for use by personnel in high-performance surface watercraft comprises a bolster adapted and dimensioned to support an occupant for shock isolation from accelerations experienced by the vessel. The bolster is mounted by pivot means extending between the bolster and a back plate which is rigidly mounted to the vessel. The pivot means permit the bolster to pivot in an arc with respect to the back plate. A shock absorber extends between the back plate and bolster to dampen the accelerations which would otherwise be passed to the bolster by the pivot means from the back plate. The bolster is capable of supporting a user in a standing position or receiving a seat assembly to allow an occupant to be seated.

Abstract: A divider element formed of a sheet member adapted to be removably coupled to a binding element of a coil bound notebook. The divider element includes a plurality of preferably T-shaped connector elements defining a narrow cut region and coil receiving aperture therebetween. Coil portions of a binding element may pass through the cut region into and out of the coil receiving aperture. The divider element is formed of a deformable material such the connector elements are adapted to be flexed out of the plane of the sheet member without substantial bending or breakage of the connector elements. The divider element may engage the coil portions of a binding element without significant manipulation of the connector elements by way of selectively urging the coil portions of a bound notebook in a direction parallel to the binding element axis.

Abstract: An apparatus for measuring the transport time of impurity particles in a plasma includes a spectrometer, a system for the spatially-resolving conversion into charge of light exiting the spectrometer, an integrator circuit for the spatially-resolving integration of the charge, as well as a display screen that presents the integrated charge as a series of spectral lines. The integrator circuit is assembled from discrete components. Thus, the transport of plasma impurities can be properly measured.
