A flame-sensitive ignitor for an explosive charge, comprising a capsule containing a primer charge sensitive to flame ignition and a foil cover for retaining the charge within the capsule, wherein a recess is formed between the foil cover and the surface of the primer charge.

A receiving device comprising a filtering section consisting of as many band-pass analysis filters as there are different component frequencies in the signals which can be received, and a processing section enabling an analysis of the energy in the individual filters.

An oil pan for a multi-cylinder reciprocating piston internal combustion engine which includes a bottom part disposed near the drive mechanism of the engine and a relatively deep part for the oil sump at one end and in which the bottom part is provided with ribs guiding the lubricating oil into the oil sump.

An improved electron shield for color picture tubes provided in the space between a supporting section of a color selective electrode, such as a shadow mask, and a gas-tight vessel to prevent unnecessary electrons from bombarding the phosphor screen. The material used for the shield is a surface-roughened aluminum sheet with metal powder not larger than 1 .mu. in grain diameter deposited in an alloy-like state on one side of an aluminum sheet as a base material. Thus, both the effective area and...

A parking light system for motor vehicles employs individual lamp elements which serve as both parking lights and as the vehicle boundary and taillights. To selectively energize the lights on one side of the vehicle, while preventing the energization of lights on the opposite side of the vehicle, a diode arrangement is connected between the light power system and the light-actuating switch.

A rotating sealing sleeve made from elastic material and intended in particular for drive joints of motor vehicles, which includes a collar of smaller diameter for the fastening at the shaft element and a collar of larger diameter for the fastening at the joint part; the collar area for the mounting of a clamping band includes outwardly a boundary collar and inwardly a relief groove which is adjoined inwardly by a further boundary collar; the width of the clamping band is thereby so selected in ...

In the known illuminating spectacles of binocular or monocular type the batteries for energizing the lamps and the means for switching on and off the lamps are disposed in a separate container which has to be carried together with the cables by the wearer. In this invention the batteries, as miniature batteries, as well as the switching means and the cables are disposed in the spectacle frame so that the user is not hindered in his work neither by a seperate container nor by cables.

A viscosity coupling, particularly for the coupling of a fan with its drive in an internal combustion engine, which has a working space that includes entrainment surfaces which are disposed opposite one another at slight distances and are provided at the two parts to be coupled with one another; the working space is connected by way of one or several openings with a reservoir space for the viscosity liquid, from which the liquid is fed to the working space as a function of an adjusting magnitude...

A method of establishing a wrap joint of a stranded wire consisting of a strand of a plurality of wires twisted together, wherein said stranded wire is wrapped around a terminal rod in a direction opposite to the direction of twist thereof. A stranded wire consisting of a strand of a plurality of wires and an insulating sheath covering said strand, said strand being twisted to such an extent that it will not be untwisted in the sheath stripping operation and further coated with a conductive mate...

The present invention is an improved adjustable locating block assembly for use on a fixture to hold a work piece. The assembly includes a locating block with a slot formed therein, a slot formed in a portion of a fixture to which the locating block is to be secured, and an intermediate block with raised surface portions on each side thereof adopted to mate with respective ones of the slots. The respective mating slots and raised surface portions have longitudinal axis extending at substantially...
