Patent EP-0109271-A3 (EP)
IPC: H01H1/52
Filed: 1983-11-10
Abstract: A high voltage multi-position type three phase electrical 
switch having stationary and movable contacts which are sup­
ported, respectively, on relatively fixed and movable contact 
supports internally of a switch casing. The contact supports 
are interchangeable and are made of a nonconductive molded 
plastic. The contact supports are adapted to selectively sup­
port either conductive contact support bars on which relatively 
stationary spring contacts are mounted, or contact blades 
which, in association with movement of a movable contact 
support, may be closed into spring contacts carried on an as­
sociated relatively fixed contact support. The movable contact 
blades comprise flexible braided electrical conductors having 
conductive contact sleeves swaged on their opposite ends so 
that the contact end portions define contact bars which are 
substantially solid in transverse cross section. In a two-posi­
tion embodiment, the contact bar ends of each contact blade 
are adapted, respectively,for fixed connection to the bushing 
connectors of service entrance terminals and for movement 
into closed circuit with corresponding spring contacts moun­
ted on the fixed contact support. In a three-position embodi­
ment, a third molded contact support is fixed within the casing 
and has similar contacts associated therewith to enable closed 
circuit connection of alternative service entrance terminals.

Title: Thread feeding device for stocking knitting machines for making a heel pocket in continuous motion
IPC: D04B9/56
Filed: 1984-01-12
Abstract: The guide system for a thread entering a stocking knitting machine having a cylindrical array of needles which rotates constantly and a supplementary thread guide which can skip over selected groups of needles to form the heel of the stocking is complemented by a supplementary concentric array of guide plates backed by an annular cam above the level of the plates alongside the tops of the needles but below the level of the cap through which the filament enters coaxially. The cam is shaped to induce a centripetal movement of the plates to be followed by a centrifugal recoil at appropriate intervals controlled by interruption of the motions of a pair of concentric toothed racks having an intermediate pinion and pins which can be intercepted by deployment of radial check rods. Slows the main array of needles to rotate continuously while causing the amount of thread deployed to be varied to suit the shape of a heel or other modification of the stacking profile so that the circumferential threads do not exhibit excessive residual tension.

Title: Semiconductor device comprising a bipolar transistor and a mos transistor and method of manufacturing the same
IPC: H01L27/06
Filed: 1986-02-17
Abstract: A bipolar transistor structure (1) which can be used in an integrated circuit where bipolar (1) and CMOS transistors (2, 3) are formed simultaneously on one substrate. In integrated circuit form the material, for example polycrystalline silicon, used for the gates (11, 21) of the CMOS transistors is also used for the emitters (29) of the bipolar transistors, the collectors of the bipolar devices are comprised by doped wells (5) in the substrate (4) and the base contacts of the bipolar devices are comprised by regions (27, 27a) equivalent to source and drain regions (17, 18) of the n-well MOS transistors and bridged by base implants (28). The conventional CMOS processing is modified by the addition of two masking steps and one implant (baseimplant). One masking step defines the area for the base implant (28) and the other masking step defines an area of the oxide (30) over the base implant which must be removed to allow contact between the polycrystalline silicon (29), which is suitably doped to provide the emitter, and the base (27, 27a, 28). The base contacts are produced in a semi-self-aligned manner.

string, the amplitude of magnetic marks above the stuck 
location will either be reduced or substantially erased; the 
electromagnetic marks below the stuck points will not be 
reduced, and the change in detected signals by the detector 
means indicates the location of the well string sticking and 
enables location of a free point in the string.

Title: Suspension of a pivoting part
IPC: E05D7/10
Filed: 1987-06-24
Abstract: A suspension mechanism is provided for a hinged part, such as the engine hood of an agricultural tractor. The top of the engine hood is pivoted on an axle via a forked bearing. A follower on the bottom of the engine hood is guided in a track on the vehicle tractor frame. A support strut is provided at the front end of the hood. So long as the support strut is attached, the hood can pivot about the axle and the follower will move in the guide track on the frame, but the hood cannot be removed because the follower cannot leave the track. To remove the engine hood, the support strut is detached from the hood. The follower then can pivot entirely free of the track and the hood can simply be lifted off of the axle support. The support strut preferably is an outwardly biased pre-loaded gas pressurized spring reaching its shortest length somewhere between the open and closed positions of the hood. The spring then will bias the hood towards its open and closed positions.
