A light pipe information display, having a non-conductive, transparent planar first glass sheet and a non-conductive planar opaque second glass sheet, both sheets being disposed adjacent to one another with their inner surfaces opposing one another in spaced-apart relationship. The second non-conductive sheet has a plurality of discrete transparent light pipes formed therethrough, wherein at least one of said non-conductive sheets includes electrical conductors disposed on its inner surface. The...

A method for generating ozone from gases containing oxygen. The ozone is generated by silent electric discharge in an installation comprising at least two gaps, which are traversed by the gas, each of said gaps being formed between an electrode and a dielectric that separates each gap from an additional electrode. According to the invention, the restriction of the volumetric flow of the gas of at least one gap is controlled.

A process is described which serves to assemble a synchronizer for a gear change box, which synchronizer comprises a hub provided with a slidable sleeve and at least one cone coupling comprising a double-conical ring, which is freely rotatable relative to the hub and is adapted to be non-positively gripped between an inner friction ring, which is connected to the hub, and a synchronizing outer ring, which is axially displaceable relative to the friction ring by the slidable sleeve, wherein the c...

An electrical cord to plug tension relief adapter and wire saver/protector is provided. The invention consists of a housing containing a cam mechanism, and a universal plug seating head that is assembled and attached securely over any selected electrical cord/plug outfit at the plug end, so as to surround, bridge, and protect the joined point of connection where the plug meets the cord. A multiple pivoting cam mechanism within the housing creates an S-Shaped slotting pattern which is configured ...

A tamping tool assembly comprises two pairs of tamping tools succeeding each other in the direction of elongation of a railroad track, two of the tamping tools of the pairs being adjacent each other and the other two tamping tools of the pairs being remote from each other. It includes a first vertically adjustable tamping tool carrier, a first crank shaft mounted on this tamping tool carrier, drives connecting the two adjacent tamping tools and one of the remote tamping tools to the first crank ...

It is desired to simplify the design of an apparatus for manufacturing annular or tubular workpieces from concrete, which comprises a mold having a vertical axis and a mold cavity between a core and a shell. The shell surrounds and is radially spaced from the core, and the mold cavity, is adapted to be filled with concrete from above a feeding and distributing devices is radially guided relative to the mold and serve to feed and distribute the concrete which is to be dispensed into the mold cavi...

A computer Tomograph having a housing with an aperture (2) for the patient in which computer-controlled scanning devices are arranged to generate computer tomograms, and into which a motor-driven, and also computer-controlled, patient's couch can be inserted from the front of the housing (1). The patient's couch also acts as an operating table, such that as little information as possible is lost in the treatment of the patient between diagnosis and the action on, or treatment of, the patient. Th...

A radiant heater, in particular for heating a glass-ceramic hot plate, has an area bearing an electrical heating element, with this area being the surface of an insulator which comprises a mounting layer and/or a thermally insulating microporous insulation layer, and having a dish-shaped enclosure which forms an annulus surrounding the insulator. The radiant heater has the mounting layer and/or the enclosure and/or the microporous insulation layer comprising a highly porous, fiber-free inorganic...

A device for displaying a sign at various heights, including a base and a pair of spaced, parallel uprights extending upwardly from the base. A cardholder is slidably positioned between the uprights with the sign being removably mounted to the cardholder. A frictional retaining force exerted between the uprights and the cardholder maintains the cardholder and the sign at various heights.

A breech closure for a barrel-type firearm is described, in which a flow passage for an igniting jet from an igniting cartridge held in a magazine extends through a breechblock. The breechblock is formed on that side which faces the magazine with a cylindrical recess, which is coaxial to the flow passage for the igniting jet and contains a metal sealing cup, the side wall of which contacts the peripheral surface of the recess and which has a bottom, which is formed with a central through opening...
