Title: Public key/signature cryptosystem with enhanced digital signature certification
IPC: G06Q20/38
Filed: 1989-01-06
Abstract: A public key cryptographic system is disclosed with enhanced digital signature certification which authenticates the identity of the public key holder. A hierarchy of nested certifications and signatures are employed which indicate the authority and responsibility levels of the individual whose signature is being certified. The present invention enhances the capabilities of public key cryptography so that it may be employed in a wider variety of business transactions, even those where two parties may be virtually unknown to each other. Counter-signature and joint-signature requirements are referenced in each digital certification to permit business transactions to take place electronically, which heretofore often only would take place after at least one party physically winds his way through a corporate bureaucracy. The certifier in constructing a certificate generates a special message that includes fields identifying the public key which is being certified, and the name of the certifiee. In addition, the certificate constructed by the certifier includes the authority which is being granted including information which reflects issues of concern to the certifier such as, for example, the monetary limit for the certifiee and the level of trust which is granted to the certifiee. The certificate may also specify cosignature requirements which are being imposed upon the certifiee.

Title: Temperature compensated thermal protector
IPC: H01H37/32
Filed: 1989-04-06
Abstract: A protective PTC device is heated by another PTC

Title: Freezing device for pourable and flowing materials
IPC: F25D3/11
Filed: 1991-05-10
Abstract: In devices for freezing pourable and flowing materials by direct contact with a low-boiling liquefied gas, the materials are moved on a conveyor belt many times through a bath consisting of the liquefied gas. These devices are well-suited for continuous production on an industrial scale, but have a high space requirement. For scientific use, for example, small easily sterilisable devices are preferred. Such a device consists of an insulated housing (1), in which a rotatable hollow cylinder (2) is arranged, the axis of rotation (3) of which is inclined at an angle to the horizontal and on the inner wall of which a band worm (5) is arranged. In the hollow cylinder, the bath (7) consisting of a low-boiling liquefied gas, for example nitrogen, is situated. Arranged above the deepest point of the bath is the introduction device (9) for the material to be frozen (Fig. 1).

Title: Real time load monitoring system with remote sensing
IPC: G01L5/00
Filed: 1991-09-26
Abstract: A system for determining the magnitude of loads on rotating helicopter components from sensor signals remotely measured on the helicopter fuselage is characterized by a controller which samples the sensor signals according to phase. These measured signals are presented to a coefficient programming module where they are combined with correlation signals to correlate the measured signal components with the desired parameter, such as flatwise bending moments of a helicopter blade. The correlation signals are established in a calibration process that determines the independent values of the measured signals using a Jones orthoganization process. The signals output from the module are recombined to provide a time dependent signal corresponding to the desired parameter. The present system avoids decomposition and recomposition of the measured signals and therefor operates in real time. <IMAGE>

Title: Ferroelectric liquid crystal device and treatment method therefor
IPC: G02F1/141
Filed: 1993-01-22
Abstract: A ferroelectric liquid crystal device is constituted by disposing a ferroelectric liquid crystal between a pair of substrates having thereon electrodes for voltage application and provided with uniaxial alignment axes, as by rubbing, so as to provide a high pretilt angle of at least 10 degrees. A problematic liquid crystal movement in such a high-pretilt angle ferroelectric liquid crystal device is suppressed by improving a smectic layer structure therein, inclusive of a symmetry of pretilt angles at the pair of substrate boundary surfaces. Such an improved smectic layer structure is accomplished by a realigning treatment after cooling to the chiral smectic phase or in the final stage of the cooling to the chiral smectic phase as by application of an AC electric field and/or by repetitive heating-cooling in the chiral smectic phase. The improved smectic layer structure is represented by, e.g., an X-ray diffraction peak having an increased peak area and/or a decreased half-value width. <IMAGE>

Abstract: A grain sorting apparatus comprises a
conveyor belt mechanism for conveying grains, fed by a
feed mechanism onto a conveying surface separately from
each other at an upstream region with respect to a
conveying direction, to a downstream end so that the
grains are discriminated and sorted by a discriminating
mechanism and a sorting mechanism when dropping from
the downstream end along a predetermined path, the belt
mechanism being disposed so that the conveying surface
thereof declines as going downstream with respect to
the conveying direction to prevent the grains being
carried by the belt mechanism from rolling toward the
upstream direction on the conveying surface of the belt
mechanism. It is therefore possible to prevent the
grains from rolling on the conveying surface of the
conveyor belt mechanism toward the upstream direction
relative to the conveying surface of the conveyor belt
even when a conveying velocity of the conveyor belt
mechanism is high.

Abstract: Voltage of a terminal (C) at a high impedance is set to
a fixed voltage (2.5 V) by a constant current source (301) and
a resistor (302), and whether the voltage of the terminal (C) is
a fixed voltage which is between 3.5 V and 5.5 V or not is
detected by comparators (303, 304) and a NOR circuit (306). A
control signal is sent from an ECU (1) to the terminal (C) to
turn on a switching transistor (401) to lower a divided voltage
so that the alternator (3) generates a high voltage only when the
voltage of the terminal (C) is the special voltage, and generates
normal voltage otherwise. In case of disconnection of the
communication line (2) or grounding of the communication line
(2), or when the battery voltage is applied to the communication
line (2), the voltage of the terminal (C) does not become
abnormal voltage but become the normal voltage. Thus, the battery
