Abstract: METHOD AND APPARATUS FOR LABEL TRANSFER                 Abstract of the Disclosure A label transfer arm having a central axis and comprising a socket body with a transfer nozzle rotat-ably mounted therein engages labels delivered to a label pickup station and transfers them to a label delivery station.  An applicator head strips the labels from the transfer arm and moves them along a fixed path from the label delivery station to a package labeling station to apply the labels to packages.  Transfer arm guiding rails are positioned on either side of the label transfer arm for engaging an eccentric collar attached to the transfer nozzle to thereby orient the transfer nozzle into a fixed angular orientation about the central axis of the transfer arm when the transfer arm is at the  label delivery station.  An operator-controllable selector ring is rotatably mounted to the socket body of the arm and is freely rotatable between selected locations defined by detents.  The selector ring is coupled to the transfer nozzle by a  torsion spring such that an operator can select one of at least two different angular orientations of the transfer nozzle about the central axis of the transfer arm when the arm is located at the label pickup station.  By selecting the angular orientation of the arm at the label pickup station and forcing the arm into a fixed angular orientation at the label delivery station, a label held by the transfer arm is rotated about the central axis of the arm by an angle equal to the difference between the selected angular orientation and the fixed angular orientation.

Title: Method and arrangement for producing a bridge for anchorage elements in dentine
Inventor: ANDERSSON KNUT M G
IPC: A61C8/00
Filed: 1987-12-08
Granted: 1992-05-19
Abstract: ABSTRACT OF THE DISCLOSURE:          A bridge for an artificial dental structure is made of titanium.  The bridge is constructed from modular elements which are adapted one to the other and are treated for joining together, for example by means of laser welding.  In a first treatment unit one or more first treatment stages are  performed  for  the  construction  of  the  bridge. Identification data introduced or utilized in this or these stages relating to the individual different heights of the anchorage elements above the dentine and their different relative inclinations and the positions and directions of the modular elements in relation to one another and to the anchorage elements are obtained and stored.  In a subsequent processing stage which is executed by a processing unit the latter is controlled depending on the extracted and stored information, so that any bridge elements present in the bridge between the attachment components of the bridge in the anchorage elements are assured a connection via the contact surfaces and directions and dimensions between the attachment components such that the bridge elements are essentially in line with the direction of the dentine in the sense of its height and width, at the same time with the necessary strength and location within the dental structure.

Title: Method and apparatus for ion etching and deposition
Inventor: MCNEIL JOHN R
IPC: B05D3/06
Filed: 1988-03-18
Granted: 1994-09-06
Abstract: ABSTRACT OF THE DISCLOSURE       The disclosure relates to a method and apparatus using ion etching and ion assisted deposition to reform a surface of an object, such as a large lens, from its existing topography to a predetermined topography.  The method comprises comparing the existing topography of the surface of the object to the predetermined topography.  In one embodiment, the comparison can be used to distinguish objects having surfaces which are readily or economically reformable to the predetermined topography from those which are not suitable for such reforming.  The method novelly utilizes an algorithm comprising image restoration.  The ion etching structure of the apparatus comprises an ion source grid which can be used to provide an ion beam of a preselected spatial distribution.  The grid is constructed of a nonconducting, vacuum compatible material, such as a ceramic sheet coated with a conductive layer on each side.  Apertures are drilled through the grid in a selected pattern.  The ion beam produced from a plasma source when a suitable voltage is applied across the coatings has a spatial distribution in accordance with the aperture pattern.  In one embodiment the coatings comprise discrete corresponding areas on each surface and different voltages are appliable to each area to further control beam spatial distribution.  Ion assisted deposition may be simultaneously performed under the algorithm to add material to the surface in accordance with the desired predetermined topography.

Title: Read head for wiegand wire
Inventor: OPIE JOHN E
IPC: G11C11/08
Filed: 1988-03-31
Granted: 1992-08-25
Abstract: Abstract A read head for a Wiegand wire has an E-core with a pick-up coil for the "1" bit wound on one outer leg and a separate pick-up coil for the "0" bit wound on a second outer leg.  The E-core is composed of a relatively thin ferromagnetic E-laminae spaced from a relatively thick E-laminae.  Between thin and thick laminae in each leg there is an appropriately polarized magnet.  The result is to establish a first field across the face of the read head between the center leg and a first outer leg.  This first field reads the one bits.  Similarly, a second field between the center leg and the other outer leg reads the zero bits.  Each one bit wire is on one side of the code strip and each zero bit wire is on the other side of the code strip so that the one bit and zero bit wires are passed respectively across the first and second reading fields provided by the read head.  Saturation of the thin E-laminae and non-saturation of the thick E-laminae assures that the field configuration is appropriate to set and switch the Wiegand wires.

Granted: 1992-03-17
Abstract: ABSTRACT          A process for the hot press moulding of moulded articles, such as the internal linings of motor vehicles or the like is described, in which planar blanks of tangled fibre mat fleece mixed with binders, using at least one mould, are permanently deformed in a multidimensional moulding process after evaporating on the mat fleece.  A stabilizing support is introduced during the deformation process on at least one side between the shaping surface of the mould and the mat fleece.  It is in the form of a fibrous sand-wich layer which is substantially elongation-free in the surface direction at ambient temperature, but is plastic-ally deformable within the hot press mould under the action of heat.  With and/or immediately after the moulding process, said stabilization support becomes a substantially elongation-free, inflexible covering.          The geometry of the flexible stabilizing support is to be made to coincide with that of the mat fleece blank to be deformed.
