Abstract: Un séquenceur de lampe pour un jouet possède des moyens simples pour faire varier individuellement le temps de mise sous tension et le temps de mise hors tension d'étage (I-II) d'une chaîne ou cycle. Chaque étage (I-II) comprend un amplificateur/commutateur (Q3, QN) de commande de la lampe dont le gain est commandé individuellement par un élément d'hystérèse (H). Lorsque la tension présentée sur un élément d'hystérèse (H) avant interruption est inférieure à sa tension établie d'interruption, l'élément d'hystérèse (H) se trouve dans son état non conducteur, donnant ainsi à l'amplificateur/commutateur (Q3) un gain négatif. La lampe commandée ne reçoit aucune tension et n'est pas allumée. Lorsque la tension présentée sur un élément d'hystérèse avant interruption est égale ou supérieure à sa tension d'interruption établie, l'élément d'hystérèse (H) se déclenche et prend un état hautement conducteur et, par conséquent, l'amplificateur/commutateur (Q3) possède un gain très élevé. La lampe commandée reçoit sa tension totale et s'allume.

Abstract: Generally, because of a slight degree of slide occurring between grooves (20a, 20b) of the Oldham's coupling proper (14) and projections (16, 18) of revolving shafts (10, 12) during the revolution, both the grooves and projections wear to form play therebetween. Accurate transmission of revolutions is unobtainable in such a state and, to cope therewith, the Oldham's coupling proper (14) is formed of an elastic material at least at bottom parts (22a, 22b) and widths of the grooves (20a, 20b) are slightly smaller than those of the projections (16, 18). Thus, each of projections (16, 18) is resiliently clamped by side walls (24a or 24b) of each groove to prevent play from being formed therebetween even after worn.

Abstract: PCT No. PCT/DE90/00888 Sec. 371 Date Apr. 30, 1992 Sec. 102(e) Date Apr. 30, 1992 PCT Filed Nov. 17, 1990 PCT Pub. No. WO91/07842 PCT Pub. Date May 30, 1991.The invention is directed to a device for clamping sheet-shaped film material onto the recording drum of a reproduction device and is directed to the operation of this device. The recording drum comprises axially proceeding suction-hole rows for the vacuum-fixing of the recording material. Suction channels, each of which connects the suction holes of a suction hole row to one another, proceed in the wall of the recording drum. A vacuum distributor controllable by the rotational movement of the recording drum is arranged in the recording drum, this controllable vacuum distributor selectively bringing the individual suction channels, the corresponding suction hole rows into communication with a stationary vacuum pump. The vacuum distributor is controllable such that that suction hole row on which the starting region of the recording material lies is first charged with vacuum during the clamping event. As a result thereof, a high initial vacuum is achieved, as a result whereof the recording material does not slip. Further suction hole rows are then successively cut-in in accordance with the increasing wrap of the rotating recording drum by the recording material and are charged with vacuum. The cut-in of further suction hole rows is ended in accordance with the respective circumferential length of the recording material at that suction hole row on which the end region of the recording material lies. In particular, large-format recording material can be clamped onto the recording drum without creating folds and warping, and can be reliably fixed thereat with the device.

Abstract: An apparatus and method for providing high resolution non-contact absolute contour measurements of an object with moire interferometry. The invention utilizes a projection moire system in which the entire projection system is translated to perform a field shift. The field shift produces a phase shift that is proportional to the height of the object. A coarse three dimensional map of the surface is first obtained from the phase shift. This is combined with high resolution relative measurements of the phase to obtain an absolute Z map of the surface. The invention does not suffer from the 2Π ambiguity problem and is suitable for prismatic discontinous structures. In addition, the present invention is applicable to industrial environments and requires a relatively inexpensive optical system. Further, the field shifting technique is applicable to fast parallel process computers thereby allowing for fast absolute contour generation of prismatic parts.

Abstract: In accordance with the present invention, aromatic ketones are prepared by the acylation of aromatic reactants using boron trifluoride as a catalyst and in a solvent medium comprising anhydrous liquid sulfur dioxide. The acylation proceeds in accordance with the equation I:
       
 wherein n ranges from 5 to 9, Ar is phenylene and n is 5, naphthalene and n is 7, or a bis phenylene radical having the structure:
       
 and n is 9; wherein Z is selected from the group consisting of a covalent carbon to carbon bond, O, S, SO₂, C=O and C₁ to C₃ alkylene or alkylidene, X is selected from the group consisting of H, OH, halogen, C₁ to C₆ alkyl C₁ to C₆ alkoxy and combinations thereof, R is an alkyl group containing from 1 to about 16 carbon atoms and Y is selected from the group consisting of hydroxy, acyloxy and halogen. 
     The acylation process of this invention gives rise to aromatic ketones which are highly selectively acylated at the activated ring carbon and also yields a high ratio of conversion of the aromatic starting material. 
     The process also provides a faster rate of reaction than analogous processes and affords the opportunity to recover large quantities of the BF₃ catalyst as well as the SO₂ solvent for recycle, thus offering improved economy and efficiencies.

Abstract: The regulator makes it possible to start different types of airplanes with a single starter, providing it the pressure and air flow required. 
     Upon the operator selecting the start step corresponding to the plane to start, the convenient rating of the turbine is set by operating a simple control that controls the flow of fuel to the combustion chamber, using the indications of a sensor that indicates to it the rotation speed achieved by the turbine. When the operation so requires, in order to obtain the pressure and air flow that the airplane needs to start, the system also activates different mechanisms. 
     As an alternative, by means of a microprocessor the start step corresponding to the plane to start can be chosen automatically, using the indications of pressure and flow at the inlet of the airplane.
