Title: Jitter compensation circuit for processing jitter components of reproduced video signal
IPC: H04N9/89
Filed: 1990-01-19
Abstract: A reproduced video signal of a VTR is applied to a 
jitter compensation circuit (100). The applied reproduced 
video signal is A/D converted by a phase modulated clock (12) 
and after subjected to the adjustment of timing (2), the 
signal is written into a memory (4). A burst signal 
period is specified based on a timing of a horizontal 
synchronizing signal in the reproduced video signal and a 
jitter amount is detected based on a sampling phase of the 
A/D converted burst. Jitter compensation data is 
calculated based on this jitter amount. On this occasion, 
latest jitter compensation data is obtained based on the 
detected jitter amount and the jitter compensation data 
one horizontal period before. A timing for starting to 
write the A/D converted video data into the memory is 
defined based on high-order data of the calculated jitter 
compensation data, thereby cancelling large jitter 
components. On the other hand, a phase of a A/D 
converting clock is controlled based on low-order data of 
the jitter compensation data, thereby cancelling small 
jitter components.

Title: Improved flexible conduit structure
IPC: A61C1/08
Filed: 1990-02-12
Abstract: An extruded conduit structure (10) is provided 
comprising a cluster of at least three tubes (12, 14, 16, 
18) connected by webs (24, 34, 36, 38) extending between 
adjacent pairs, the tubes (12, 14, 16) and webs (24, 34, 36, 38) 
being formed by simultaneous extrusion of a suitable plastic 
through a suitable die. The outer surface (26) of each of the webs 
(24, 34, 36, 38) is convexly curved in an arc that is 
substantially tangential with the outer surfaces of the 
adjacent pair of tubes (12, 14, 16). The inner surface (28) of each 
of the webs (24, 34, 36, 38) is flat relative ot the 
outer surface (26) and forms a cord of such arc whereby 
each of the webs (24, 34, 36, 38) will be of minimum thickness (T₁) along 
each of its junctures with the adjacent webs (24, 34, 36, 38). 
This construction substantially eliminates any concave 
surfaces on the exterior of the conduit (10) within which 
foreign matter may collect and the webs (24, 34, 36, 38) can be easily 
stripped along the tubes (12, 14, 16) to expose the tube ends for 
connection to the apparatus to which they are to be connected.

Title: Device for obtaining a load signal from a mechanically sprung and driven axle of running gear comprising a lift-axle
IPC: B62D61/12
Filed: 1990-04-30
Abstract: 2.1 The axle load of the mechanically sprung drive axle of running gear comprising a lift axle can be described by the spring deflection of the suspension spring and the pressure of the lift bellows. A known device has a signal body which can be displaced axially by the pressure and rotated by the spring deflection. A three-dimensional characteristic diagram is arranged on the signal body and determines for each constellation of rotation position and axial position a distance which forms the axial load signal to be obtained. Because of the signal body with the three-dimensional characteristic diagram the known device constitutes a complex solution, particularly when the lift axle running gear is only operated with rigid axle load participation of the lift axle, i.e. with only fully raised or fully lowered lift axle. 2.2 In order to simplify the known device, particularly for the last-mentioned mode the invention proposes to displace the signal body (22) axially, independently of the spring deflusion, and to replace the three-dimensional characteristic diagram by a two-dimensional contour (21, 33). 2.3 Preferred application area is vehicle technology. <IMAGE>

Title: Method and apparatus for increasing the processing capacity of optical digital processing systems having optically bistable devices
IPC: G06E1/00
Filed: 1990-04-11
Abstract: An optically bistable device, such as a symmetric self 
electro-optic effect device (S-SEED) (1,2), is forced into a 
metastable state prior to the incidence of an optical input signal 
thereto, thereby increasing the sensitivity of the optically 
bistable device to the optical input signal (P IN1 , P IN2 ), 
reducing both the switching time and the optical input signal energy 
required to switch the device. The metastable state is entered into 
by one of three techniques: 1) turning off the bias voltage V₀ of 
the device with optical bias beams on then turning on the bias 
voltage V₀ with the optical bias beams off; 2) applying a 
predetermined voltage (via 3,4) to a node in the device, the 
predetermined voltage being substantially the metastable state 
voltage or V₀/2; or 3) subjecting the device to equal intensity 
optical bias beams having a wavelength longer than the exciton 
wavelength. In the second case, optical bias beams and optical 
input signal beams may be applied simultaneously with the 
application of the predetermined voltage. In the last case, optical 
bias beams (at the exciton wavelength) and the optical input signal 
beams can be applied simultaneously after removal of the 
long-wavelength optical bias beams, thus saving switching time. In 
addition, the optically bistable device may be selectively placed in 
the metastable state and the optical input signal have sufficient 
energy to switch the device only when it is in the metastable state. 
This allows for multiple optically bistable devices to be 
selectively responsive to a common optical input signal, such as in 
a demultiplexer.
Patent EP-0399717-A3 (EP)
IPC: C10J3/14
Filed: 1990-05-15
Abstract: The present invention relates to the 
coproduction of a combustible gas stream usable as an 
energy source, a sulfur-dioxide-containing second gas 
stream usable as a source of oxidant in the 
gasification of coal, and a sulfur-dioxide-containing 
third gas stream usable as a feedstock for the 
production of sulfuric acid. The process includes 
heating coal in a coal gasification zone in the 
presence of an oxygen and sulfur dioxide-containing 
atmosphere under partial coal gasifying conditions to 
produce a carbonaceous char and a crude coal gas 
stream. Sulfur-containing compounds are removed from 
the coal gas stream and converted to elemental sulfur. 
The carbonaceous char is combined with gypsum to form a 
feed mixture. The non-gypsum portion of the feed 
mixture contains sufficient reducing potential to 
release substantially all of the sulfur in the gypsum 
as gaseous compounds of sulfur in a +4 or lower 
oxidation state. The feed mixture is heated under 
reducing conditions to produce a 
sulfur-dioxide-containing second gas stream recovered 
at an early stage of the reaction, a 
sulfur-dioxide-containing third gas stream and a solid 
sintered product. The sulfur-dioxide-containing second 
gas stream is recycled back to the gasification zone to 
provide the oxidant for the coal gasification.

Inventor: PARTRIDGE III B WARING
IPC: H04W4/16
Filed: 1995-02-28
Abstract: The prior art deficiencies are solved, in accordance with the disclosure
herein, by maintaining a list (24,25,26) of caller identities and by determining, via
reference to this list, the type of call treatment that an incoming call should receive.
This technique may be termed "divergent call treatment". The caller identities may
be telephone numbers. The list of telephone numbers may be stored in the telephone
company's switching facilities (12) or in the subscriber's telephone instrument. A
wide range of call treatment options are provided, and these options can be
performed regardless of whether the list is maintained in the telephone company's
switching facilities or in the subscriber's telephone instrument. 
     In connection with cellular telephones (e.g. 28), the divergent call
treatment technique of the present invention is used to particular advantage. In
accordance with one of the embodiments disclosed below, for example, the list
maintained is a list of accepted callers, and it is maintained by the telephone service
supplier. When a call comes in, a determination is made as to whether the caller is
an "accepted" caller. If so, the call is forwarded to the cellular telephone (28).
Otherwise, the caller is offered the option to pay for the call. A willingness on the
part of the caller to pay for the call is indicated by a signal from the caller. This
signal may be, for example, the pressing of one or more keys on a standard DTMF
touch-tone pad, such as #1. In response to such a signal, the call is forwarded to the
cellular telephone. In the absence of such a signal, the call is disconnected or
diverted, for example, to the land line phone of the cellular telephone subscriber. 
     When the list of accepted callers is maintained in the subscriber's
telephone instrument, means are included to attenuate the ringing signal for an
interval sufficient to provide appropriate call treatment for the call and, optionally,
means are included for call forwarding, and/or recording of incoming messages.

Abstract: In a speech decoding apparatus, a conversion
unit converts a received encoded signal into a parameter
in units of frames. A memory repeatedly updates and
stores the parameter representing a pause state and
output from the conversion unit for the pause interval
of the speech signal. A synthesis filter coefficient
generation unit generates a synthesis filter coefficient
on the basis of the parameter read out from the memory.
A smoothed filter coefficient generation unit generates
a smoothed filter coefficient on the basis of the
synthesis filter coefficient output from the synthesis
filter coefficient generation unit. The smoothed filter
coefficient generation unit generates the smoothed
filter coefficient which is smoothed such that the
synthesis filter coefficient changes in accordance with
a count value of the frames during the predetermined
period. A background noise generation unit generates
background noise on the basis of the parameter read out
from the memory for the pause interval of the speech
signal. A smoothing filter performs filtering
processing of the background noise output from the
background noise generation unit by using the smoothed
filter coefficient output from the smoothed filter
coefficient unit and outputs smoothed background noise.
