Granted: 1989-01-04
Abstract: A switch in which a screen inserted between the contacts shears the opening arc. The screen is associated with a sheath that surrounds a contact support and slides on the latter when the gas pressure it is subjected to causes it to move at a velocity which is a function of the energy of the arc. The switch is applicable in particular to protective apparatus designed to limit fault current or breaking devices in which steady-state current is fairly high.

Granted: 1991-01-16
Abstract: A magnetic rotary head recording/reproducing apparatus in which a magnetic head is mounted on a piezoelectric element so that the head follows a recording track. A scanning track in the next head scanning operation, a voltage waveform applied to the piezoelectric element, and a tape speed are calculated based upon a central value of the present voltages applied to the piezoelectric element and the present tape speed. The calculation is effected for every scanning by the head, so that noiseless reproduction can be continuously performed at any tape speed. When the tape speed is to be changed, furthermore, the speed instruction is changed incrementally so that a desired speed is reached. That is, even when the tape speed is changed, noiseless reproduction is still realized.

Abstract: A method of increasing the resistance to pull out of a screw (20) screwed into a receptive substrate (35) which comprises unscrewing the screw and removing it from the hole and then locating a spiral member (140) having an outwardly facing pointed profile and having a cross section such as to fit between adjacent turns of the thread on the screw, and such that the dimension of a turn perpendicular to the longitudinal axis of the spiral (herein called the radial depth) is greater than the height of the thread of the screw with which that turn will be associated, in the threaded hole and screwing the screw into the hole, the spiral member engaging the hole and the screw threadly engaging the spiral member and forcing the pointed profile into the substrate. The spiral member is preferably of intermediately malleable material e.g. an aluminium alloy. The bottom end (146 or 182) of the spiral member is shaped so as to be disconnectably engageable by a tool (50 or 160). Application in the field of screw-in rail spikes in wooden sleepers.

Abstract: PCT No. PCT/EP85/00356 Sec. 371 Date Apr. 16, 1986 Sec. 102(e) Date Apr. 16, 1986 PCT Filed Jul. 18, 1985 PCT Pub. No. WO86/00873 PCT Pub. Date Feb. 13, 1986.A mobile bucket mechanism for collection and conveyance of a bulk material which includes buckets carried by chains over generally vertically arranged sheaves, a support structure for the sheaves which drives the chains to move the buckets in a path to collect bulk material located at a lower end of the path. A feeding device is driven by the support structure to cut into the bulk material and feed the bulk material to the buckets. The feeding device includes a stationary, jacket-like cylindrical body surrounding the path of the buckets and the lower portion of the supporting structure. The cylindrical body has an opening adjacent a portion of the path along which the buckets are carried upward by the chains. A cutting head surrounds the cylindrical body and has essentially radially oriented blades rotatable with respect to the cylindrical body so as to supply the bulk material to the opening. In the preferred embodiment, a ball bearing equipped rotary connection to the supporting structure has an upper ring connected with the supporting structure and a lower ring supporting the cutting head. The supporting structure has a supporting ring which is fastened to the cylindrical body. Since all cuts provided by the mechanism are generated by the rotating cutting head and are transmitted directly into the supporting structure by way of the ball bearing equipped rotary connection, the forces on the buckets and their guides are relieved. The buckets then perform only a scooping and not a cutting movement.

Dans une variante, la porte flottante est formée à partir d'une première couche de polysilicium, et les électrodes d'écriture à partir d'une deuxième couche de polysilicium. La deuxième électrode d'écriture peut être formée par une région de substrat (42).

Abstract: The cap for the writing instrument comprises a jacket mounted slidably on a sealing insert or sleeve which provides a sealed moisture chamber for the writing tip when the cap is on the writing instrument. Near the writing tip there is a circular bulge on the shaft of the writing instrument which enters into a sealing engagement with an interior passage of the sealing insert. On putting the cap on the writing instrument the sealing insert is pushed over the circular bulge until it contacts a contacting stop on the jacket. Then the circular bulge presses tightly into the sealing insert and it locks the jacket to the writing instrument so that the entire arrangement is kept in that position until the cap is removed. A signal slider is attached with the sealing insert which is extendable out from the end of the jacket in order to signal in its extended position the proper seating of the cap on the writing instrument. Erroneous indications of a sealed state are prevented with our invention.

Abstract: Method and apparatus suitable for inclusion in an integrated circuit transceiver meeting IEEE 802.3 standards which detects "collisions" so that more than one station will not simultaneously transmit over a network. The method employs a novel three-pole cyclical low-pass filter (20) which attenuates the ac component received over the network to less than 20 mV to allow collision detection within the 900 nanosecond budget allowed by the IEEE standard. A differential operational amplifier (18) receives the signal from the network and a collision reference voltage. The signal generated by the differential amplifier is filtered by the low-pass filter and then coupled to a high-gain comparator (22) which acts as a zero-crossing detector. The comparator generates ECL logic signals representing the occurrence or non-occurrence of a collision. The resulting collision detector operates over a wide range without the need for field "trimming".

Abstract: A membrane filter comprises one or several tubular flow channels (1) for liquid which is to be treated in the filter. The walls of the flow channels consist on the inner side of membranes, which are supported by a supporting structure. An outer casing (2) surrounds the flow channels and limits a collection space (5) for permeate between the casing and the flow channels. According to the invention the flow channels (1) and the said collection space (5) are connected to separate outer circuits, comprising pumps to bring the liquid which is to be filtered (retentate) as well as permeate to circulate concurrently pass the membrane filter. The collection space is filled by filling bodies, which constitute an essential mechanical hinder for the flow of circulating permeate. Means in the form of disks (8) provided with holes, which abut against the outer casing, are arranged at the inlet to the flow channels. These means are arranged to retain the filling bodies in the collection space and distribute the flow of circulating permeate over the same.
