Abstract: Acoustic level sensing apparatus is provided, in which pulses of acoustic energy are transmitted by an electrically energized transducer towards a surface to be sensed, and the electrical output from the transducer following the pulse received by a receiver is digitized and analyzed by a programmed microprocessor to detect a return echo from the surface, so as to produce a digitized echo profile. The digitized echo profile is enhanced by removing narrow peaks likely to correspond with certain types of spurious echo (REMOVE_NARROW_ECHOES_F0), and narrow valleys which may represent fragmentation of a wanted echo (REFORM_FRAGMENTED_ECHOES_F0). Echoes are identified by comparing the profile with a time varying threshold generated derived from a linear regression performed on part of the echo profile (TVT_IN_F2), various different types of comparison being performed and their results combined (ALF_ALGORITHM) prior to selecting the most likely true echo on the basis of the combined results (SELECT_BEST_ECHO_FROM_FILE_3).

Abstract: A local area network for interconnecting terminals and other users and data processing systems and other service providers over a communications link. The users and providers connect to the communications link by means of interface units each of which may connect to several users or providers. The interface units communicate over the communications link by means of messages. When a user requires the use of a service, the interface unit establishes a virtual circuit between it and the interface unit connected to the service provider and a service session which allows the user and the service provider to communicate over the virtual circuit. If several users connected to the one interface unit as the first user require services provided by providers which connected to the same interface unit as the first provider, they communicate in sessions over the same virtual circuits. The session messages are accumulated into single virtual circuit messages that are acknowledged in unison by the receiving interface unit. Each virtual circuit in the users' interface units includes a timer which reset when a message is transmitted over the virtual circuit and a data waiting flag set whenever data is present to be transitted over the virtual circuit. The interface units are inhibited from transmitting over a virtual circuit unless the timer has timed out and the data waiting flag is set.

Abstract: A die assembly for plastic pelletizing apparatus of the type including a cooling bath into which the plastic is extruded. The die assembly includes a heated main body (10) having first and second oppositely disposed exterior faces (18; 20) connected by a plurality of relatively small extrusion passageways (22). A layer of thermal insulation material (40) overlies the second face (20), and a cover member (44) having an outer surface adapted to be exposed to the cooling bath is positioned over the thermal insulation material and joined to the main body. Wear resistant insert members (52) formed from a material having a higher coefficient of thermal conductivity than the material from which the cover member (44) is made extend from the outer surface of the cover member through the layer of insulation into the main body. Extrusion outlet orifices are formed through the insert members (52) and define continuations of the extrusion passageways (22) of the main body (10). The relationship between the inserts (52), the cover (44), the insulation (40), and the main body (10) produces an increased heat flow from the main body to the outer die face in confined areas about the orifices. This heat flow advantageously reduces the possibility of freeze-off and plugging of the orifices due to premature solidification of the extruded plastic.

Abstract: A television signal distribution system protects outgoing programs from unauthorized reception; and marks or tags the conveyed signals with a digital word identifying the class of viewers authorized to receive the program ("level of service"). Basic encription is accomplished by effectively suppressing the horizontal and vertical synchronizing information. Horizontal sync information, and the program-characterizing level of service word which is interleaved in time with prescribed horizontal sync pulses, is distributed via pulse amplitude modulation of the audio carrier.At subscriber receiving stations, the sound carrier amplitude modulation is recovered to permit level of service authorization verification; and to reconstitute the video carrier to receivable form by an amplitude modulation which is the inverse of the sync-suppressing modulation of the head end.In accordance with one feature of the present invention, a further data channel may be employed to vary subscriber service authorizations - as to permit pay-per-view billing.

Abstract: PURPOSE:To obtain concentrated irradiation to the part that is not covered by the irradiation of a headlamp by making the gradient of the irradiating direction variable characteristics smaller (larger) if the steering angle is over (under) the predetermined steering angle, in varying the irradiating direction of a lamp light means in linkage with the handle steering operation. CONSTITUTION:The pulse-shaped electric signal corresponding to the amount of revolution of a revolving disc 1 is produced from a photosensor 2 that is placed in the vicinity of a revolving disc 1 whose movement is linked with the handle steering, and this electric signal is input into a control signal producing circuit 3. This producing circuit 3 periodically produces the control signal with a pulse width corresponding to the steering angle, and this control signal is input into a servo-motor control circuit 4. Next, an electric motor 46 is controlled in such a manner that the directional discrepancy between the actual direction of irradiation of a headlamp as a lamp light means and the target direction of irradiation determined based on this steering angle is eliminated, thereby changing the direction of irradiation of the headlamp to the proper direction. In this case, the motor 46 is controlled in such a manner that the gradient of the irradiating direction variable characteristics becomes large if the steering angle is smaller than the preset angle and becomes small if the steering angle is greater than the preset angle.

Abstract: A conveying apparatus for panels is equipped with two revolving endless conveyor belt members such as chains etc. The chains are connected with each other with successively arranged transverse organs such as cross bars. On each cross bar there are mounted displaceably with braking two panel-engaging devices comprising clamping springs for gripping and transferring panels from a charging to a discharging station past a random number of intermediate processing stations. Two pneumatically operable pusher members push the panel-engaging devices into contact with the lateral edges of an arriving panel and cause the clamping springs to grip the panel. At the discharging station, two separating pusher members of similar construction open the clamping springs and push the panel-engaging devices apart toward their terminal positions at opposite ends of their cross bar, thus setting the panel free to be discharged from the apparatus.

Abstract: Open-pored sintered glass is produced by conventional processes but, at pore volumes of more than 60%, the resulting tensile bending strengths are too low for an application as a filter medium. A further disadvantage for filtration is the wide distribution of the pore size and the structuring of the internal surface of the pores. The novel process is intended to provide open-pored sintered glass with large open pore volume, high tensile bending strengths and good flow rates. 
<??>In this process, starting granules of finely granulated glass powder, coarsely grained salt powder and binder are first prepared. 5 to 20% by weight of fine-grained glass powder is then added to these starting granules and this mass is subjected to shaping. The shaped product as formed is heated to the sinter temperature of the glass and sintered, and the salt is then washed out of the sintered glass.
