Title: Travelling-wave tube with confined-flow periodic permanent magnet focusing
IPC: H01J23/087
Filed: 1989-04-05
Abstract: Traveling-wave tube (10) has a confined-flow 
periodic permanent magnet focusing arrangement (26) in 
which either the first magnet (60f) or the third magnet 
(60t) from the electron gun (12) has an extent along the 
electron stream path one-half that of the remaining 
magnets (60) in the arrangement (26), thereby providing a 
magnetic potential of essentially zero on the electron gun 
pole piece (46). This enables a magnetic field to be 
provided in the region of the electron gun (12) between 
the gun pole piece (46) and a location behind the cathode 
(14) due solely to the magnetic field leaking through the 
gun pole piece aperture (50).

Patent EP-0333409-A3 (EP)
IPC: H01H35/34
Filed: 1989-03-13
Abstract: An automotive transmission control is shown having 
pressure switches to sense the state of actuation of solenoid 
valves to provide logic signals to a microprocessor type of 
transmission control. The pressure switches, which sense the 
pressure of hydraulic fluid controlled by the solenoid 
valves, use a dished shaped metallic diaphragm characterized 
in that the pressure-deflection curve of the center of the 
diaphragm has minimal hysteresis and reflects that the 
diaphragm is relatively stiff having a positive coefficient 
of pressure with increasing deflection up to and above a 
selected pressure level at which level the center accelerates 
between d₁ and d₂. The diaphragm is loosely held on a 
conductor at 0 psig with the fluid pressure when it increases 
forcing the diaphragm into sealing and electrical engagement 
with the conductor.

Title: Pulse train interruption sensing circuit
IPC: G01R31/34
Filed: 1989-06-23
Abstract: The interruption of an alternating pulse train (for example that 
produced by an open collector transistor driven on and off by a fan 
rotation sensor) is detected by a circuit comprising:  
an input node (13) to receive the pulse train;  
voltage conversion means (15, 18, 22, 26 and 28) connected to the 
input node for converting the pulses of the pulse train to a steady state 
DC signal level higher than the voltage level of the alternating pulses; 
and  
comparator means (36) connected to the conversion means for comparing 
the DC signal level with a reference voltage,  
the comparator means producing an output when the DC level of the 
conversion means falls below the reference voltage level as a result of 
the absence of pulses from the pulse train regardless of the state in 
which the pulse train is interrupted.  
     The circuit design ensures that the steady state voltage level decays 
to an under voltage value when the pulse train stops regardless of whether 
the fan output stops in a high or low state.

Patent EP-0388093-A3 (EP)
IPC: H04N1/327
Filed: 1990-03-09
Abstract: This invention allows unmodified CCITT Group 3 and 
4 facsimile transceivers to interactively select and 
retrieve facsimile pages from a shared facsimile data 
base FAX server system ("FAX server"). The remote 
facsimile transceiver user marks a paper selector 
sheet form using a pencil or pen. The selector sheet 
is transmitted via the remote facsimile transmitter, 
preferably in a turn-around polling mode, to the FAX 
server unit. The FAX server unit processes the 
facsimile signal rapidly, interpreting the selector 
sheet and selecting the pages desired to be retrieved 
prior to the normal CCITT Recommendation T.30 timeout, 
which would otherwise abort the line connection. The 
invention allows the requested information to be 
returned during the same telephone call. If 
turn-around polling is not available, then the FAX 
server initiates alternative strategies culminating in 
an automatic callback with the information desired. 
The capability created allows facsimile transceivers 
to be used as interactive terminals for selective 
retrieval of text and graphics, without requiring 
alphanumeric keyboard interaction or the need for 
manual intervention.

Title: High-efficiency gear transmission
IPC: F16H3/44
Filed: 1990-07-10
Abstract: High-Efficiency gear Transmission of the present invention relates to the field of gear transmission technique, particularly to a high-efficiency double internal gear planetary transmission with small tooth number difference. High-Efficiency Gear Transmission of this invention provides with an entirely new double-ring gear and extra short toothed gears with changed gear parameters in order to obtain high transmission efficiency with reduced power loss in bearings and gear engagement. High-Efficiency Gear Transmission according to the invention comprises at least one double-ring gear composed of two integrated coaxial gear rings. Said double-ring gear having different tooth numbers on each ring is mounted on an eccentric shaft through planetary bearings. The double-ring gear performs planetary movement with two fixed-axle gears respectively. The vertical projections of the tooth widths of the two gear rings of said double-ring gear on their common axis at least partially coincide with each other. Both said gear rings are composed of either outer or inner gears. The distance between the projections of the center lines of their tooth widths in the direction of their common axis is zero. The distance b between the internal surface of the outer gear ring of said double-ring gear and the external surface of the fixed-axle gear engaged with the inner gear ring of said double ring gear must be not less than twice the eccentric distance a of the eccentric shaft. If the double ring gear and the fixed-axle gears engaged with it are all helical gears, the two internal helical gears are of the same hand, and so are the two external helical gears. The high-efficiency gear transmission is provided with an extra short toothed gear pair with changed gear parameters. Its addendum coefficient ha is less than 0.5, the absolute value of its modified coefficient difference X is not more than 0.1, preferably equal to zero, and the modified coefficients of both extra toothed gears are preferably equal to zero. The two internal helical gears are of the same hand and so are the two external helical gears while said extra short toothed gear pairs are used for the two internal gear pairs of the double internal gear planetary transmission.

Patent EP-0529536-A3 (EP)
IPC: G06F9/38
Filed: 1992-08-21
Abstract: A Recovery Control Register is embodied as two multi-bit registers; a staged register and an immediate register. The immediate register contains the information which is read by the CP microcode and used during recovery. The staged register is a platform where a footprint can be assembled by the CP microcode before the retry checkpoint is changed. The CP microcode can operate on either register through the use of "SET", "AND" and "OR" functions. The choice of these operators as well as the decision to separate the registers into bit ranges provides the microcode with maximum flexibility when setting up new checkpoint values. When a recovery algorithm requires that the recovery footprint change immediately, microcode operates on the immediate register. If, however, the recovery footprint needs to be synchronized with the event which requires the change, for example a store being released, the microcode puts the appropriate footprint into the staged register and issues a release signal to the completion/interrupt logic within the CP. When the release is processed and broadcast as a Completion Report a variable number of cycles later, the checkpoint is advanced and the immediate register is updated in the same cycle, thereby allowing for a crisp transition from one recovery window to the next. <IMAGE>
