Title: Process for the production of photographic copies from photographic copy masters on a photographic copy apparatus
Inventor: FRICK BEAT
IPC: G03B27/32
Filed: 1993-02-04
Abstract: Process for the production of photographic copies from photographic copy masters on a photographic copy apparatus ABSTRACT   Process for the production of photographic copies from photographic copy masters in a photographic copy apparatus, wherein initially in a measuring station of the photographic copy master an exposed photographic master material, on which photographic copy masters are exposed, is analyzed master by master. In the process, the measuring data necessary for the exposure of each master is determined, together with the size and the position of the center of each copy master on the film. A number is assigned unambiguously to each master, the number being determined by scanning an expanded DX code provided in periodic intervals in a border area of the master material by a single bar code detector used in the measuring station to read the expanded DX code. The number is determined by reading the expanded DX code. The numbers assigned to the copy masters, together with the associated measured data, are passed on to a computer and control unit. In an exposure station, located downstream from the measuring station in the direction of transport of the master material, the copy masters are exposed according to the measured data belonging to the prevailing copy master number present in the computer and control station onto photographic copy material to produce photographic copies. The number assigned to each copy master is applied to the photographic copy, preferably to the reverse side.

Title: Minimization of gto gate driver losses when antiparallel diode conduct
Inventor: KUMAR AJITH K
IPC: H02M1/08
Filed: 1992-07-24
Abstract: A power conversion system for supplying AC power to a multiple phase, AC electric motor includes an inverter comprising a plurality of independently controllable switching devices for selectively coupling each phase of the motor to a source of unipolar electric power. A control processor selectively gates the controllable switching devices for controlling power to the motor. Each of the switching devices is bypassed by a respective one of a plurality of antiparallel connected diodes. The control processor in combination with current sensors determines the magnitude and direction of current in each phase of the motor. The control processor inhibits gating of the controllable switching devices when current in an associated one of the diodes exceeds a preselected magnitude so that the switching devices are not gated during a time at which the devices are reverse biased. In this manner, power consumption and heat dissipation in the devices and the associated gate driver circuit are reduced.

Title: Battery cartridge having a recess for detecting misuse and/or recessed terminals
Inventor: MITSUI HIDERO
IPC: H01M50/262
Filed: 1993-05-21
Abstract: A battery pack having a detection recess formed along a center line of a bottom surface arranged such that the detection recess is engaged with a convexed portion of a battery charger.      Therefore, whether or not the battery pack is properly attached to the battery charger can easily be detected by the inclination of the battery pack about the center line. Further, a battery pack is arranged such that an aperture is formed on an outer surface of the battery pack and an output terminal is inwardly disposed on the aperture. Therefore, damage to the batteries in the battery pack caused by a short-circuit resulting from products made of conductive metal material such as a key ring, necklace, or chain contacting both of the output terminals, as occurs when terminals are disposed on the outer surface of the battery pack, can be prevented. Furthermore, the battery pack includes apertures with output terminals disposed therein for discharging dust or the like away from the terminals into the interior of the casing or out of the casing through a hole.      Therefore, the accumulation of dust or the like within the apertures and upon the output terminals is prevented.

Title: Low permeability subterranean formation testing methods and apparatus
Inventor: BLAUCH MATTHEW E
IPC: C09K8/58
Filed: 1993-06-23
Abstract: Abstract of the Disclosure The present invention provides methods and apparatus for determining the gas permeability of very low permeability subterranean  formations  as well  as  the gas permeability reducing effects of injecting one or more treatment fluids thereinto.   A gas is injected into a core sample of the formation at a selected substantially constant pressure, and the injection is continued for a long period of time to insure steady state flow conditions.  The temperature of the gas as it flows through the core sample and the flow rate of the gas exiting the core sample are measured, and the native state gas permeability of the core sample is calculated therefrom.  One or more treatment fluids can be injected into the core sample after  the  native state  permeability   is  determined.          Thereafter, the gas permeability can again be determined and compared to the native state permeability.

Title: Power Factor Correction Circuit for AC to DC Power Supply
Inventor: BEASLEY DENNY D
IPC: H02M1/42
Filed: 1993-06-23
Abstract: A saturating-inductor (112) or transformer (114) is used to shape input current flowing into an alternating current (AC) to direct current (DC) power supply (100) to correct the power factor for the supply. If a saturable inductor (112) is used, it is connected to feed current into the power supply (100) and a capacitor (113) is connected across the input of the power supply. The capacitor precharges the saturable inductor to a point just short of saturation during a preliminary portion of each sinusoidal half cycle of the input AC power. For steady state operation, this is the point at which current will start to flow into the AC to DC power supply and the inductor will saturate. Since the inductance falls in accordance with the permeance curve characteristic of material used to construct the inductor, the current will continue to flow at the same or an increasing level despite the declining voltage level of the AC input power.
