For a lock comprising a bolt, a keeper in which the bolt is engageable in the closing position of the lock and means for shifting the bolt. The safety device comprises delayed-action means for blocking the bolt and precluding displacement of the bolt in the direction for opening the lock a predetermined interval of time after the bolt has been displaced an initial partial distance in the direction for opening the lock by the shifting means.

An elastic cover for disposition over supporting members or work pieces and a method of applying the cover thereover. The cover is a hollow tube of highly expandable elastomeric material which includes gripping means such as longitudinal ribs provided on its outer surface so that the tube may be expanded by outwardly directed forces acting on the ribs. The tube, before expansion is incapable of positioning over the member but after expansion, the tube is capable of positioning over the member an...

An article of footwear such as a sock, a pair of tights, combinations or any similar garment having at least one foot formed of knitted textile fabric and provided with a sole of flexible material having a fibrous structure, the sole being attached to the foot by means of a molded side portion of flexible plastic material which adheres to textiles and covers at least part of the periphery of the foot and of the sole.

The incentive seating module comprises: a structural frame provided with a gaiter, a frame, disposed above said structural frame and provided with an arch, whereby the structural frame exhibits planar symmetry, means for connecting the frame to the structural frame comprising a joint enabling the frame to swivel in relation to the structural frame about an axis which is perpendicular to the symmetrical plane, and a seating element joining the frame to the gaiter, made of an elastic membrane whic...

A semiconductor device includes: groups of memory cells that are connected to word lines; and select gates that are controlled by control word lines and are connected to the groups of memory cells, each of the select gates being capable of storing protection information for a respective one of the groups of memory cells.

The invention relates to a method for producing electrochromic devices, in particular that having a large working surface area and which does not produce a volumetric shrinkage and can operate during a long maintenance of electrocoloured state of an electrochromic compound, high control voltages and polarity inversion. The inventive electrochromic device comprises at least two electrodes (1, 2), at least one of them being optically transparent. A closed sealed space is formed between said electr...

The invention relates to an apparatus and method for identifying teleconference participants. More particularly, the invention relates to a conference system that includes an initialization means for initializing a call between participants located in at least two remote stations and an identification means for identifying one of the participants in one remote station responsive to a request from another of the participants in another remote station. The initialization means comprises table mean...

A coating device is provided which has a bar which coats a coating liquid on a strip-shaped body conveyed in a given direction, and a dam-shaped member disposed at an upstream side of the bar so as to face the bar. Also provided is a coating method which, in the coating device, supplies the coating liquid from between the dam-shaped member and the bar so as to carry out coating. A flow rate of the coating liquid passing through a gap between the strip-shaped body and the dam-shaped member is set...

A tool arrangement includes a tool unit 2, e.g. a cutting apparatus 2', a spreader 2'', a squeezing device or the like, and a drive 3, a control and/or switching clement, as well as a first operating-medium circuit 4, in which tool arrangement a second operating-medium circuit 5 is provided, which is actively connected to the first operating-medium circuit 7 by a pressurized-media converter 6.

A semiconductor device includes: memory blocks each having groups of memory cells that are connected to word lines; select gates for selecting the groups of memory cells; and an apply circuit that applies, at the time of reading data, a back bias to the select gates of unselected memory blocks.
