Title: Method and apparatus for controlling geometrically simple parallel mechanisms with distinct connections
Inventor: GRIFFIS MICHAEL W
IPC: B23Q1/54
Filed: 1991-05-01
Abstract: A system, method and apparatus for controlling, via a closed-form forward displacement computation, the position and orientation of a movable platform of a parallel mechanism. A movable platform is supported above a base platform by a plurality of parallel support legs such as linear actuators. The dimensions of the base platform and the movable platform, as well as the lengths of the support legs, are provided to a control system. The control system is operative to compute at least one closed-form forward displacement solution (51) of the geometry of polyhedron (an octahedron for the disclosed embodiments) formed by the movable platform, the base platform, and the support legs. The control system determines a final position and orientation of the movable platform by eliminating imaginary roots of the closed-form solutions and roots which would result in discontinuous paths of travel for the movable platform. A novel special 6-6 parallel mechanism (Fig. 12) is also disclosed. The control system is suitable for controlling known 3-3 or 6-3 Stewart platforms in a novel manner, as well as controlling the novel special 6-6 parallel mechanism. The special 6-6 parallel mechanism is distinguished from a general 6-6 by the fact that it is geometrically reducible to an octahedron, and therefore it has a simple geometry, even though its legs possess distinct connections. Also disclosed is a method for reducing the novel special 6-6 parallel mechanism to a Stewart platform equivalent, which is then controlled by the disclosed closed-form forward displacement control system.

Title: Multiphase switching system and gnerator arrangement having such a switching system
Inventor: WIDENHORN LEONHARD
IPC: H02B13/02
Filed: 1993-04-01
Abstract: ABSTRACT OF THE DISCLOSURE         In the case of the multiphase switching system (1), each (for example L3) of the phase conductors is arranged in the course of a generator output line (2), which is arranged between a generator (7) and a network transformer  (8),  together with a switching apparatus, in encapsulation (5) which is insulated by air gaps, in a manner isolated from the other phase conductors.        The  switching  system  is  intended  to  allow virtually   all   the   switching,   protection,   and measurement   functions   occurring   in   a   generator arrangement to be executed despite a compact and space-saving construction.        This  is  achieved  by  the  switching  apparatus (three-position interrupter switch 10) having at least two switching positions. A first of these two switching positions is arranged between the generator (7) and an output of the switching system (1) which acts on the network  transformer  (8).  A  second  of  these  two switching positions is in contrast located between the generator  (7)  and  a  current  connection  (20)  of  a starting  device  (21)  which  is  located  outside  the encapsulation (for example 5) and acts on the generator (7) when the first switching position is open and the second switching position is closed.        In the case of a generator arrangement which is equipped  with  such  a  switching  system  (1)  a  load interrupter switch or interrupter switch, which is used for the current connection of the starting device (21) to the generator (7), can be saved.

Title: Tdma mobile unit frequency synthesizer having power saving mode during transmit and receive slots
Inventor: JOKURA JUN
IPC: H04B7/26
Filed: 1993-04-13
Abstract: During transmit and receive slots of a TDMA frame, a reference pulse source is made inactive for power savings purposes, and during an idle slot of the frame it is rendered active to supply pulses to a phase alignment circuit where initial phase alignment is established between an output of a frequency divider and the reference pulse. Phase-aligned signals are supplied to a phase comparator, the output of which is coupled to a switched filter bank during the idle slot to cause a selected loop filter to develop a voltage according to the output of the phase comparator to drive a voltage controlled oscillator to generate a local carrier for allowing a channel switching to be effected for a possible hand-off. The connection between the phase comparator and the filter bank is cut off during the transmit and receive slots to maintain that voltage for a closed-loop operation during the next idle slot.

Title: Microbially-produced antibody fragments and their conjugates
Inventor: HORWITZ ARNOLD H
IPC: C07K16/00
Filed: 1992-06-15
Abstract: Recombinant DNA methods are described for the production of antibody F(ab')2 and Fab' fragment molecules from transformed microorganisms such as bacteria and yeast. The recombinant F(ab')2 and Fab' fragments are secreted from the host cells and may be recovered directly from the fermentation culture. These direct methods of F(ab')2 and Fab' production are advantageous over existing art methods by avoiding proteolytic digestions and obtaining homogeneous molecules. Methods are described for the conjugation of these fragments, by methods targeting either available lysine amino acid residues or selectively-reducible cysteine residues, to active moieties such as ricin toxin A chain. The microbially-produced F(ab')2 and Fab' fragment molecules and their immunoconjugates have a wide variety of therapeutic and diagnostic uses.
