Title: Signal multiplexing circuit
IPC: H04M11/06
Filed: 1985-06-26
Abstract: Bidirectional communication of voice analog and data message signals over a two wire telephone line (16) that inter-connects several electronic key telephone station sets (18) with a digital access circuit (13) of a central data and voice communication facility (19) is achieved by a multiplexing circuit that functions either as a set interface (17) for a telephone or as a line card interface (11) for the access circuit (13). Data messages originating at a key pad (52) of any set or which are input to an interface bus of the multiplexing circuit are stored in a shift register (23) for subsequent modulation of a high band carrier signal, but only one interface (11) (17) may enter a transmission mode at one time. Transmission priority is therefore assigned by a controller (25) to the interface (11) (17) that first attempts transmission on an inactive line (16), i.e., in the absence of the carrier signal. With transmission initiated, all other interfaces (11) (17) enter a monitor mode to listen but not act on the transmitted message. Errors in transmissions caused by line noise, or collision transmissions between two or more interfaces (11) (17) are resolved via message transactions between the interfaces. Retransmission priority based on the unique addresses of the calling interfaces (11) (17) resolves collision issues with priority going to the lowest address. Controllable transmit and receive equalizers (36') (37') define analog signal paths in the line card interface (11) and are always in an operational mode. Corresponding equalizers (36) (37) in the set interface (17) are normally quiescent and become fully operational only after a correct address match between calling and called interfaces (11) (17) occurs and the called interface responds with a line signal acknowledging receipt of a valid message. A codec (20) may then be enabled and bidirectional communication between a set (18) and the facility (19) is established with voice and signalling being frequency division multiplexed on the line (16).

Abstract: Das Verfahren betrifft die Vergütung von Holz aus 
Splintholzbäumen wie Buche, Birke, Ahorn, Pappel u.a., das 
eine hohe Schwind- und Quellverformung und eine geringe 
natürliche Dauerhaftigkeit aufweist. Dieser Mangel kann 
durch Tränkung mit Gerbstofflösungen beseitigt werden, die 
als Tannine in Pflanzen vorkommen oder synthetisch herge­
stellt werden. Die Einlagerung der Gerbstoffe in die Zellwän­
de anstelle des die Schwindung und Quellung verursachen­
den Wassers ist für die Wirksamkeit des Verfahrens entschei­
dend. Dieser Effekt wird durch eine Wärmebehandlung 
erreicht, die auf Holzart und Gerbstoffart abzustimmen ist.  
     Durch diese Wärmebehandlung werden aus relativ 
geringwertigen Splinthölzern hochwertige Spezialhölzer, die 
vor allem eine hohe Dimensionsstabilität aufweisen. Sie 
eignen sich daher besonders für die Verwendung unter 
wechselnden klimatischen Bedingunger und unter Außenbe­
dingungen. Das Anwendungsgebiet betrifft Fenster, Türen, 
Fassaden, Fußböden sowie weitere Verwendungszwecke, 
bei denen eine hohe Paßgenauigkeit erforderlich ist. Ferner 
eignet es sich für Musikinstrumente und für die Herstellung 
plattenförmiger Produkte, z.B. Sperrholz und Schichtholz.

IPC: H01L21/265
Filed: 1986-07-17
Abstract: A method of using removable sidewall spacers (24) to 
minimize the need for mask levels in forming lightly doped 
drains (LDDs) (28,36) in the formation of CMOS integrated 
circuits. Aluminum or chemical vapor deposition (CVD) metals 
such as tungsten are suitable materials to form removable 
sidewall spacers (24) which exist around CMOS gates (18,20) 
during heavily doped source/drain region (20,28) implants. 
Other materials such as CVD polysilicon may also be useful for 
the sidewall spacers (24). The sidewall spacers (24) are 
removed before implantation of the lightly doped drain regions 
(28,36) around the gates (18,20). This implantation sequence 
is exactly the reverse of what is currently practiced for 
lightly doped drain (28,36) formation. The invention also 
includes the use of a differential oxide layer (32,34). A 
second set of disposable sidewall spacers (24) or the use of 
permanent sidewall spacers (40) form optional embodiments.

Title: Method and arrangement for information transmission betwmethod and arrangement for information transmission between users of a bus system een users of a bus system
IPC: G06F13/42
Filed: 1986-12-11
Abstract: To increase flexibility and system capabilities, it is proposed to provide a call-up command bus (4) instead of an address bus. Via this call-up command bus (4), instructions which are elements of a high- level system command language and which are designated by call-up command code (9) are transmitted from a central station (1) to peripheral devices (2). Call-up command codes (9) can be used for giving different orders to peripheral units (2) as users on the bus system, which trigger certain processing functions at these peripheral units. In addition, call-up, and codes (9) can be used for making different determinations, for example with respect to the protocol and data protection processes which apply during the run period of a bus procedure (10) which is also determined by this means. <IMAGE>

Patent EP-0266215-A3 (EP)
IPC: G01F1/32
Filed: 1987-10-30
Abstract: A device such as a vortex flowmeter wherein the magnitude of a 
physical parameter is determined by sensing the frequency of vibration 
of a sensing body (7) which is caused to vibrate at a frequency 
representative of the parameter. In the case of a flowmeter, the 
sensing body (7) extends into a fluid at a location downstream of a bluff 
body (5). Vortices generated by the bluff 
body cause the sensing body (7) to 
vibrate at a frequency representative of the flowrate. A flexible 
element (15) is secured to the sensing body (7) 
and to a support (23) for the sensing 
body at respective first and second locations. 
Between these first (25) and 
second (27) locations the flexible element (15) 
has a curved section (29). Vibration 
of the sensing body (7) varies the distance 
between the first (25) and second (27) 
locations and causes the curved section (29) 
of the flexible element (15) to 
vibrate in a direction transverse to the vibratory movement of the 
sensing body (7) and with a greater amplitude. The vibration of the 
flexible element (15) modulates radiation conveyed thereto by optical 
fibres (17, 19).

Title: A television receiver having means for the suppression of line flicker
IPC: H04N5/21
Filed: 1988-08-25
Abstract: In TV receivers line flicker occurs at horizontal transition or separation lines between a light and a dark picture area as reproduced in successive half pictures in respective positions mutually vertically displaced by one line width, whereby the separation line is jumping up and down. This is counteracted by a detector (18) continually detecting the distribution of the intensity of the video signal in an area vertically above and underneath the picture spot and producing a correction signal whenever a significant difference of intensity is detected. This signal is fed to or generated in a control unit (20) which affects the vertical deflector system (6) in a manner such that in one or both of the half pictures the line under reproduction will be displaced to such an extent that the said separation line in both of the half pictures will be reproduced in entirely or approximately the same geometrical height position on the screen, whereby the said jumping is eliminated or reduced.

Patent EP-0334303-A3 (EP)
IPC: G01N3/32
Filed: 1989-03-21
Abstract: Electrical circuitry is useful for thermomechanical analysis 
apparatus. A sine-type wave force signal is generated by 
combining a triangular wave with an alternating wave equal in 
magnitude to about half of the square of the triangular wave. 
The triangular wave is generated with a control voltage 
proportional to the operating frequency. A response wave of the 
apparatus is amplified by an active filter circuit with corner 
frequencies approximately equal to each other and proportional to 
the operating frequency to process the wave independently of 
frequency. The force wave and response wave are converted to 
square waves which are combined to form pulsed time signals 
representing a phase difference for each half cycle. A pair of 
analog switches are receptive of the control voltage and 
responsive to the respective time signals to feed a switched 
output to an integrating capacitor such that successive voltage 
levels are effected in proportion to the time signals and the 
control voltage. Sample hold modules receptive of the voltage 
levels effect a steady voltage output representative of average 
phase shift independently of operating frequency and any time-­
varying DC level in the response wave.
