  • Patent number: 6832868
    Abstract: A writing implement comprising a housing (2), a writing cartridge (4) arranged in the housing in a movable manner, and a control unit that displaces the writing cartridge between a first position in which the cartridge tip (6) protrudes from the housing for writing, and a second position in which the cartridge is retracted into the housing. In the first position the writing implement has a total length suitable for writing, and in the second position the writing implement is contracted. The writing implement exhibits improved handling without major structural modification, so that the writing implement can be brought into the writing position and also extended in a single hand movement. To achieve this the implement is provided with a depressor (8) which is configured as an extension of the housing and can be actuated to move the writing cartridge between the first and second positions, and which in the first position extends out from the rear end of the housing.

  • Patent number: 5135108
    Abstract: The relay with water tight baseplate includes grooves in the region of the baseplate, through which (the grooves) the joining pins of the relay reach, and the inner space between the grooves and the joining pins is tightly filled with a casting mass. For this better distribution of the casting mass, the rabbet canals are arranged in the baseplate and the glue is positioned in the rabbet canals. The rabbets can hereby be formed as one-sided, open profile canals, or also as an enclosed canal system, which simply strikes the region around the grooves with casting mass (FIG. 1). The relay also includes connecting structure between the baseplate and the cap which utilizes rabbet/groove structure filled with casting mass.

  • Patent number: 4709219
    Abstract: In a miniaturized electromagnetic relay wherein an insulation is provided in a housing separating the magnet and contact system, there are provided a rib integral with the housing having a dogleg for partially encapsulating the armature and a pocket on the actuator for the nesting of a free swivelling end of the armature.

  • Patent number: 4623863
    Abstract: The polarized, electromagnetic relay includes a magnet frame, relative to conduit rabbets, with angles-off yoke arrangement, which includes two separated, parallel-arranged yokes, as well as a permanent magnet that lies therebetween and between anchor plates. The two yokes are L-shaped and formed exactly identical, whereby their core shanks stretch over the entire length of the exciter coil, and lie next to each other in the region of the exciter coil. Thereby a mechanically and electrically absolutely symmetrical magnet frame results, whose asymmetry is compensated by losses arising from the air gap. Through the use of individual yokes there ensues a simple assembly in the spring jack, which functions as holding element for all of the parts.

  • Patent number: 4618842
    Abstract: The present disclosure refers to a miniature relay with a spring bracket serving for mounting a magnet coil and spring contact bank. The base of the spring bracket is provided with plug or solder connections towards the outside, with a view to providing the most compact construction possible with a simultaneous, far-reaching separation of plug or solder connections for the coil winding and a contact bank. It is also within the context of the present invention that the longitudinal axis of the magnet coil is arranged perpendicularly to the longitudinal axis of the spring contact bank.

  • Patent number: 4571567
    Abstract: An electromagnetic relay especially such a relay with a spring jack, that serves for holding the magnet coil and the contact spring jump. In the simplest form of the relay, it includes the feature that the individual contact springs of the contact spring jump are provided with one piece fitted flat plugs, which are positioned in grooves in the ground wall of the spring jack, and in such position are securely fixed from the standpoint of strength and form.
