Abstract: In an alarm transmitter having a monitoring unit arranged on a movable glass pane or door to be monitored and having an alarm transmitter and a fixed distributor coupled inductively to the transmission unit in the desired position of the glass pane or door, which distributor is connected to a signalling central processing unit, the distributor has for the inductive coupling to an oscillatory circuit of the transmission unit its own oscillatory circuit which is connected in a first switch position to a first oscillator by means of a clock-controlled selection switch in order to operate as transmitter and is connected in a second switch position to a signal evaluation circuit for signals transmitted by the transmission unit in order to operate as receiver. As a result, an exact evaluation of the signalling state of the alarm transmitter is possible. <IMAGE>

IPC: H04N11/04
Filed: 1988-04-27
Abstract: This system contains a hybrid coder which codes the incoming data of a video picture block by block. At the receiver end, a hybrid decoder reverses the coding steps of the hybrid coder. The incoming blocks of a video picture are, among other things, transformed by a transformation unit (T) and quantised in a quantiser (Q). To make the system optimally adaptable to transmission bit rates of between 64 kbit/s and 2 Mbit/s, a structuring unit (SE) is provided which combines several blocks, which represent a coherent section of a video picture, to form a macroblock. To each macroblock, it assigns a macroattribute which shows which characteristics are considered to be identical for all part-blocks of the microblock and which are not. Such characteristics include, for example, information on the movement vector of each part-block which, for example, can be equal for all part-blocks. 
<??>If a separate macroattribute (NON) is used, there is no characteristic which is considered to be equal for all part-blocks of a macroblock, instead, the characteristics are allocated to each part-block itself. 
<??>If necessary, the macroblocks themselves, in turn, are treated like part-blocks, that is to say combined to form even larger units. This results in a particularly effective coding during the transmission of still pictures.

Abstract: A method and apparatus for cooling a hot product gas containing sticky particles which lose their stickiness upon cooling. Hot product gas from a reactor is passed along at least one cooling section (I) consisting of a quench wall (1) provided with a porous wall region (A), an inlet (2) and an outlet (2a) for coolant and a flexible means (3) adjacent to the inner side of the quench wall and its rims being sealingly connected therewith. A coolant is supplied through the inlet (2) and the porous wall region (A) into the space formed by the quench wall (1) and the flexible means (3). The flexible means (3) is moisturized with the coolant, and the coolant is vaporized thus bulging the flexible means (3). The vaporized coolant is discharged through the outlet (2a) so that the flexible means (3) collapses to its start position and these steps are repeated.

Abstract: A socket assembly 18 for making a push-fit coupling with a spigot end of a tube 12 comprises a socket portion 22, a snap cap 44 fitted to the socket portion and having a central hub 64 extending both axially and radially inwardly of the mouth of the socket portion, and a gripper member 42 retained in the socket portion by the abutment member.

Abstract: A V BB  input (18) threshold potential with feedback circuitry is used to stabilize all of the logic inputs on a GaAs IC to ECL compatible levels over a normal temperature range and normal power supply variations. The system called "V BB -Feedback" uses "zero translation delay" direct Capacitor Diode Fet Logic (CDFL) inputs. This is an extension of the CDFL circuit approach in which the voltage across the input level shift circuitry on all inputs is adjusted to maintain a threshold voltage equal to the dc potential on an "extra" V BB  input (18) in spite of variations of temperature, power supply voltages or processing parameters such as MESFET pinchoff voltage. A dc potential (V BB ) is applied to the "extra" V BB  input (18), which is an additional input that is essentially identical to the actual logic inputs. All of the logic input threshold voltages are then slaved to the V BB  dc potential applied to the "extra" V BB  input. ECL compatability is accomplished by combining a reasonably compliant, but uniform, CDFL voltage shifter (34) with feedback circuitry (55) to maintain the shift voltages at proper levels thereby achieving the desired input logic threshold.

Abstract: The binding of a nucleic acid probe with its complementary sequence in a targeted, single stranded nucleic acid is affected by the secondary and tertiary structure of the target nucleic acid. The rate and extent of hybridization of the probe with the targeted nucleic acid can be increased by the use of "helper" oligonucleotides. Helper oligonucleotides are selected to bind to the target nucleic acid and impose a different secondary and tertiary structure on the target to facilitate the binding of the probe to the target. The resulting hybrid of probe and target nucleic acid also exhibits a higher T m  than the hybrid which results from addition of the probe alone.

Abstract: A blind rivet, for anchoring in relatively soft material such as softwood, comprises a tubular shell (14) with a weakened portion (19) at the end remote from the head (18), and a stem (15) with an enlarged head (29) having a smooth underhead curve (32). The weakened portion (19) of the shell has four longitudinal V-section grooves (24) on its inner wall. In addition, the weakened portion (19) has a wall thickness which is less than that of the remainder (22) of the shell, the junction between the two parts presenting an internal annular shoulder (23). When tension is applied to the pulling portion (26) of the stem, the stem head (29) enters the weakened portion (19) and splits it apart along the grooves (24) to form legs which anchor in the soft material. The higher strength of the remainder part (22) of the shell prevents the stem head passing beyond the shoulder (23) before the stem fractures at the breakneck (27).

Abstract: A hybrid sample rate servo motor employing rate feedback compensation is disclosed. The system employs a shaft encoder (55) having a predetermined resolution to provide position data which are pulses indicating the shaft has moved another resolution unit. Under high motor velocity conditions the rate compensation feedback loop (60) is operated at a conventional constant sample rate. Under low velocity conditions, the sample rate at which the rate compensation feedback loop is operated is modified so that rate samples are taken and calculated only when new position data are available from the motor encoder. Rate quantization error is substantially reduced, thereby leading to more robust controller operation.

Abstract: In Trellis coded modulation system in which an input digital signal in parallel form is encoded by a convolutional encoder which adds an additional bit to the input digital signal for error correction purpose, and a mapping circuit designates amplitude and phase for each symbol for QAM signal, the number of parallel bits at output of said convolutional encoder is the same as the number of parallel bits of an input digital signal. An input digital signal is first rate converted so that m+n bits in every T period is converted to m bits in every T′ period, where T′=(m/(m+n))·T. The convolutional encoder adds n number of bits so that the total number of parallel bits is m+n, which is applied to the mapping circuit. In a receive side, a receive signal having m+n bits in every T′ period is decoded through an error correction decoder which provides m bits in every T′ period, then, the decoded signal is rate converted to m+n bits in every T period. So, the number of parallel bits does not increase in spite of convolutional encoding, but a transmission rate is a little increased. The coding gain in the present invention is improved since the number of levels of the QAM signal is not increased although the bandwidth of the signal is a little increased because of the higher clock rate.

A support structure for the permanent magnet is formed from an array of electromagnets (18a-d, 20a-d) which partially surround the permanent magnet. Current signals are controllably applied to the electromagnets (18a-d, 20a-d) through driver circuits (25a-d) to generate a magnetic support field for supporting the permanent magnet (12) and its mounted objective lens (14). Sensors (22a-d) are provided for sensing the charge inherent in the electret material (16) as a function of the position of the electret material (16) from the sensors (22a-d).
