Abstract: ABSTRACT OF THE DISCLOSURE           The invention relates to a method of suppressing unwanted indications in automated ultrasonic testing of a test piece.  In order to improve the suppression of unwanted indic-ations, in particular in the case of extended statistical suppres-sion, a variable discriminator threshold is derived from the highest of all maximum amplitudes by means of a predetermined amplitude difference.  The ultrasonic signals are not evaluated as flaw signals when only the variable discriminator threshold is exceeded but are evaluated as flaw signals only when addition-ally at least the highest of all maximum amplitudes exceeds the fixed discriminator threshold preset for the testing operation.

Abstract: ABSTRACT OF THE DISCLOSURE A  transformer  utilizing  a  rotating  flux  for saturating the entire core.  The transformer uses a core configured such that a vector sum of the induction pro-duced by two windings in the core rotates through 360°. This is accomplished by arranging the component induction vectors to be perpendicular and the source voltages asso-ciated with each of the component induction vectors to be 90° out of phase.  If the inductions are of equal magni-tude and the vector sum is sufficient to  saturate  the core, rotation of the vector sum saturates the entire core and the  transformer  experiences  a  very  low  or  nearly negligible hysteresis losses.  Various topological confi-gurations for the core, including a toroid, are described. The  transformer  windings  can  be  arranged  for  single, two-phase, three-phase, or multi-phase operation.

Abstract: ABSTRACT OF THE DISCLOSURE           High-purity silicon bars can be produced by electrically melting a portion of a mass of silicon granules in a crystal so that the mass around the melt isolates the melt from the crucible wall and thereby prevents contamination of the melt from the crucible and softening of the crucible wall by the melting heat.          The current flow is promoted by the heating of the silicon grnaules and/or electrodes and a seed can be lowered into the melt so that a bar can be withdrawn therefrom for cutting up into wafers for use in the production of semiconductors.

Abstract: MANUALLY LOADED ENVELOPE FEEDER                         Abstract An envelope feeder sequentially feeds envelopes from a loading station to a printing station of a conventional printer for addressing, and releases addressed envelopes at a discharge station.   The  feeder  includes  an  upstanding  housing  that journals a platen roll at its lower end and an idler roll at its upper end.   The  feeder's platen roll replaces the printer's conventional platen roll and serves to drivingly connect the feeder to the printer.  The housing has a front guide surface that faces forwardly with respect to the printer, and a rear guide surface that faces rearwardly.  At least two transport belts have reaches that extend along the front and rear guide surfaces.   The belts extend around and are held taut by the feeder's platen and idler rolls.  Envelopes to be addressed are loaded manually,  one  at  a  time,  at  the  loading  station by opening a door to permit each new envelope to be positioned in engagement with  the  transport  belts,  whereupon  the  door  is closed to assist in maintaining proper envelope positioning.          The transport belts have lugs that are brought into engagement with trailing edge portions of newly loaded envelopes for moving envelopes along the travel path from the loading station to the printing and discharge stations as the belts are caused to move in response to rotation of the feeder's platen roll by the printer.   The  printing,  discharge  and  loading  stations  are located at closely  spaced positions  along the  front of  the feeder, with the loading station above the printing station, and with the discharge station therebetween.

Abstract: ABSTRACT OF DISCLOSURE       A method and apparatus are described for producing optically satisfactorily laterally spaced letters which have been sequentially transferred from a dry transfer sheet.  The sheet (28) is held in a holder (20) which incorporates a short free-motion linkage enabling the sheet so held to be moved horizontally over a short distance, the short distance being accurately repeated each time such movement is effected.  By butting the letter next to be transferred to the letter just transferred and then moving the fixed distance away, visually pleasing letter spacing may be simply achieved without the use of extra transferable markings which need to be transferred to the working surface and subsequently removed, and without the need for excessively complex apparatus or for drawing alignment or spacing lines on the receptor.

Abstract: ABSTRACT     The seat (27) of a chair is pivotally connected to its carrying arm (14) by means of a horizontal shaft (42) disposed at the front edge of the seat.   The arm (14) is mounted on a supporting frame (12) extending behind the seat (27) and can be adjusted thereon to various heights.  A spring mechanism is provided, the energy accumulating means of which is a helical spring.  The pre-stressing of the helical spring can be adjusted depending on the user's body weight so that the seat (27) is held in suspension by the spring mechanism (F) within a middle range of  the pivot  angle.        Thus,  the user  can  effect  a comparatively strong rocking motion of the seat (27) by relatively small shift of the centre of gravity while unintentional rocking movements are avoided to a large degree.

Abstract: ABSTRACT       A method of forming a thin silicon layer upon which semiconductor devices may be constructed.  An epitaxial layer is grown on a silicon substrate, and oxygen or nitrogen ions are implanted into the epitaxial layer in order to form a buried etch-stop layer therein.  An oxide layer is grown on the epitaxial layer, and is used to form a bond to a mechanical support wafer. The silicon substrate is  removed using grinding and/or HNA, the upper portions of the epitaxy are removed using EDP, EPP or KOH, and the etch-stop is removed using a non-selective etch.  The remaining portions of the epitaxy forms the thin silicon layer.  Due to the uniformity of the implanted ions, the thin silicon layer has a very uniform thickness.

The third component can be a solid ring of steel, for example, or it can be a laminated core containing shorted electrical conductors. In starting from standstill, the power windings are energized with A.C. power and this produces a circulating electrical current with the third component of the rotor which reacts to produce rotational torque.     After the rotor reaches about 70 to 80% of synchronous speed, the excitation coil is energized and this will produce strong alterating magnetic flux in the pole piece which magnetizes the layer of the permanent magnetic material into a pattern of north and south magnetic poles in the proper phase with the rotating field of the stator so as to produce a powerful rotational torque that accelerates the rotor to a predetermined synchronous speed.
