Title: Controlling plasma discharge display panel - using pulse control signals generated by sequence circuits that are applied to hold cathode and anode electrodes
Inventor: KIM DAE-IL
IPC: G09G3/296
Filed: 1993-01-20
Abstract: The control method for a plasma discharge panel display involves using a sequence circuit to select scanning electrodes in the form of a cathode by applying signals to the bases of transistors. A synchronous sequential circuit transmits data signals to the anodes. The anode signals consist of a positive pulse, the cathode of negative amplitude pulses and the hold signal is in the form of repeated pulses. The display has an anode (11) on an upper glass panel (10) surface, a hold electrode (13) on the surface of a lower glass panel and a dielectric (14) located in between. A cathode (15) is enclosed within the dielectric. ADVANTAGE - Avoids coupling between write and discharge operations.

Title: Safety plate heat exchanger
Inventor: FUNKE KARL-HEINZ
IPC: F28F3/00
Filed: 1993-04-23
Abstract: The invention relates to a safety plate heat exchanger having a plurality of heat exchange elements which are assembled to form a packet and between which safety gaps provided with a heat exchange medium are formed and which consist respectively of two spaced plates between which there are formed flow gaps through which a first and a second heat exchange medium alternately flow via inlet and outlet openings formed in the plates. In order even in the case of a leak in the region of the inlet and outlet openings to prevent one heat exchange medium entering the circuit of the other heat exchange medium, and in order to monitor such a leak in a simple way, the plates (8) and (10) of one heat exchange element (4, 40, 50) respectively have two projections (18) and (20) which stand clear of the plate rim. The plates are joined to one another congruently so as to form the heat exchange elements. Each plate and thus each heat exchange element (4, 40, 50) has only two through openings (22, 24) and (42, 44) and (52, 54), which are constructed in the projections which stand clear. The heat exchange elements (4, 40, 50) are arranged one after the other alternatingly in the packet in a fashion rotated relative to one another such that the projections of the respectively next but one heat exchange element are aligned with one another and the through openings in the aligned projections arranged one behind another ...

Title: Balancing appts. for manually guided manipulators
Inventor: BITTENBINDER WOLFGANG A DIPL I
IPC: G01L1/22
Filed: 1994-05-04
Abstract: The appts. includes a piston rod of a pneumatic cylinder (13), a load support (20) and an electrical controller. The piston rod acts on the load support which supports a load (21) to be manipulated. A load sensor (19) between the support and piston rod produces a load dependent signal to control an electropneumatic pressure control valve via the electrical controller. A pressure then is fed to the pneumatic cylinder to hold the load stationary.The load sensor, arranged directly adjacent to the support, is designed with regions or elements which accept and propagate bending moments arising from lateral displacement of the centre of gravity of the load w.r.t. the load sensors line of action.  Other regions or elements of the sensor are not influenced by the bending moments and are only subjected to the force arising from the load.  The latter regions or elements carry electrical measurement elements which output an electrical signal proportional to the load.
