Title: Retard feeder with pivotal nudger ski for reduced smudge
Inventor: SARDANO PETER A
IPC: G03G15/00
Filed: 1990-12-20
Granted: 1994-12-13
Abstract: In a retard type bottom sheet separator/feeder 80, in which the bottom of a stack of original document sheets is driven downstream, to a separation nip with a retard pad 62 by the planer upper flight of a driven frictional separator bottom feed belt 50, that feeding is assisted by a normal force applying ski or shoe unit 70. The unit 70 pivotally lowers arm assembly 76so that a large area planar bottom of a ski 72 is overlying the belt 50. The ski 72 rides on the top of the stack with low friction with a preset downward normal force. A pivotal mounting 74 thereof allows the free self-pivoting of the bottomsurface of the ski 72 into continuous alignment with the plane of the top of thestack, pressing the stack between the ski and an opposing feeding belt area which is also maintained uniformly planar by a special belt supporting system. Thus the normal force is distributed evenly over a relatively large area. A dualaxis gimbaled mounting 74 of the ski 72 allows the ski to adjust to various different stack heights and maintain adequate total normal force while preventing high pressure points or pressure concentrations which could cause smearing by providing a large ski area of contact with evenly applied low pressure thereover.

Granted: 1993-11-09
Abstract: ABSTRACT OF THE DISCLOSURE    A high frequency amplifier circuit comprises an amplitude characteristic correction circuit and a phase characteristic correction circuit for compensating the non-linearity of the input-output characteristics of the amplifier.  The amplitude characteristic correction circuit varies the drain voltage or the collector voltage of the amplifier in accordance with the envelope level of an input signal in such a manner that the relationship between the amplitude of the output of the amplifier and the amplitude of the input signal has linearity.  On the other hand, the phase characteristic correction circuit provides a quantity of phase shift to the input signal in accordance with the envelope level of the input signal, and the phase-shifted input signal is applied to the amplifier in such a manner that the phase of the output of the amplifier and that of the input signal coincide with each other.

Title: Method for channel adaptive detecting/equalizing
Inventor: KAZECKI HENRY L
IPC: H04B7/005
Filed: 1991-08-19
Granted: 1995-07-04
Abstract: In a communications device, two coherent detection al-gorithms (102 and 103), one of which has a decision feedback equalizer (103), and a detector selection algorithm (104) are used to dynamically select a detector depending on whether delay spread distortion is present. First the correlation of the detector without the equalizer (102) is measured. If this corre-lation is greater than a predetermined threshold, the data from that detector (102) is used by the communications device. If the correlation is less than the threshold, the correlation of the detector with the equalizer (103) is measured. If this is less than the correlation of the detector without the equalizer (102), the data from the detector without the equalizer (102) is used, otherwise the data is taken from the equalizer (103).

Title: Non-repudiation in computer networks
Inventor: HOLLOWAY CHRISTOPHER JAMES GEO
IPC: H04L9/32
Filed: 1991-10-31
Granted: 1998-05-05
Abstract: The invention supplements the use of a conventional authentication token such as a MAC or DSG, to provide very strong evidence of the origin of an electronic message. A new   type   of   authentication   token,   known   as  the Non-Repudiation Vector  (NRV) is attached to each message sent across a data network. The NRV cryptographically links each message sent or received by a particular data processor on the network to previous and subsequent messages handled by   that   data   processor,   to   create   a   chain   of cryptographically linked messages. The burden of proof for the repudiation of a message is transferred to the sender of a  message,  who  must  demonstrate  how  the  sending data processor could have moved through the time period during which the disputed message was sent, without generating the NRV corresponding to the disputed message.

Title: Processing of carbon steel furnace dusts
Inventor: BARRETT EVERETT CLARK
IPC: C22B3/20
Filed: 1991-11-08
Granted: 1999-03-16
Abstract: In a process for the hydrometallurgical treatment of electric arc furnace dusts which includes an acetic acid leach, the acetic acid solution used to perform the leach  is made strong enough to dissolve heavy metal residues in the dusts, the iron-containing residues of which are recycled to a steel producing furnace.  Zinc and other heavy metals are precipitated from hot acetic acid solution  as  useful  products by  the  use  of hydrogen sulphide.  Calcium is then precipitated from the acetic acid solution as a clean gypsum using a deficiency of sulphuric acid, thus avoiding leaving sulphate ions in solution in sufficient concentration to interact with the dust and form sulphates in the iron containing residues when the acetic acid is recycled to the leaching step.

Title: Connection control method for personal communications
Inventor: UCHIYAMA YASUYUKI
IPC: H04M3/42
Filed: 1993-10-07
Granted: 1999-03-30
Abstract: The present invention relates to a connection control method for personal communications. In accordance with the present invention a switching center which is comprised of a first memory part, a second memory part and a third memory part. The first memory part stores a terminating terminal number which corresponds to each subscriber. The terminating terminal number is registered by each subscriber. The second memory part stores idle/busy information corresponding to each terminal. The third memory part stores idle/busy information corresponding to each subscriber. When a subscriber makes a call at a terminal, the switching center determines whether the idle/busy information for the subscriber stored in the third memory part is busy or idle. When the idle/busy information represents an idle, the switching center refers to the idle/busy information for the terminal stored in the second memory part. When this idle/busy information represents idle, the switching center interrogates the terminal number of a terminating terminal of a terminating subscriber stored in the terminating terminal memory part, i.e. the first memory part, and performs an outgoing call connection process. At this point, the switching sender also sets the idle/busy information for the subscriber and the terminal to a busy state. When the subscriber makes a call, while the terminating terminal is performing an incoming call connection process for the subscriber, since the idle/busy information for the subscriber has been set to the busy state, even if the terminal is idle, the switching center does not perform an outgoing call connection process for the subscriber at the terminal.
