Abstract: @ A continuous, multi-phase process for debossing and perforating a substantially continuous web of substantially planar polymeric film to coincide with the image of one or more forming structures, each having a patterned forming surface with a multiplicity of holes and an opposed surface. Each forming structure is open from the holes in the forming surface to its opposed surface. The web of film has an indefinite length, a first surface, a second surface and a thickness. The thickness comprises the distance between the first surface and the second surface. The process comprises at least two sequential.forming phases, one of which involves three-dimensional conformance of the web to the macroscopic profile of the forming structure and another of which involves aperturing of the web to coincide with fine-scale apertures in either the same or a separate forming structure. The order in which the phases are carried out will depend upon the properties desired in the resultant macroscopically expanded, three-dimensional, apertured polymeric web. Because the process is carried out in sequential phases, previously incompatible characteristics which could not be provided by prior art single-phase forming processes can now be achieved.

Abstract: This invention is concerned with an analogue calendar watch able to display the hour, the day of the month perpetually, and whenever required, the number of the month via the day of the month display. The watch includes a first motor driving the time display in response to a time base signal, a perpetual calendar circuit including a day counter, a month counter and a year counter and receiving a daily signal supplied by a contact, a control circuit connected to the calendar circuit, and a second motor driving the day of the month display in response to a signal from the control circuit. The display of the number of the month is achieved with a reading circuit that receives from the calendar circuit signals representative of the contents of the day and month counters. The reading circuit issues to the second motor, in response to a month call signal, a control signal to change the day of the month being displayed to the number of the month, and a further control signal to move the day of the month display back to its original position.

Abstract: In a digital demodulator for demodulating the broadcast information service for drivers (ARI) and the radio data system (RDS) signals, the RDS signal should always be present at the same output terminal independently of whether the ARI carrier is present or not. In a demodulator constructed in accordance with the principle of a Costas loop circuit, this is achieved by the fact that the control variable of the Costas loop is inverted for the voltage-controlled oscillator as soon as an ARI carrier is present, which is detected by an additional fast ARI detection circuit. <IMAGE>

Title: Tracking control circuit for an optical pick-up
IPC: G11B7/095
Filed: 1988-08-17
Granted: 1993-03-17
Abstract: In the case of an optical pick-up for CD players, the track error signal TE is, for example, obtained from the difference between two photoelectric voltages ES and FS. If, for example due to mechanical impact on the CD player, the light beam jumps from the data track to be picked up, it can be directed back onto the correct data track by means of information contained in the subcode, which however impairs the sound reproduction. In the case of unformatted optical recording media, however, this possibility of correction does not exist. 
<??>In order to direct a laser beam (8) which has jumped from the data track to be picked up back to this data track accurately and quickly, it is established by means of a direction logic (5) and a forward- backward counter (6) by how many tracks the light beam (8) has deviated to the right or left from the data track to be picked up. The correction signal for the tracking control circuit is obtained from the counter reading.

Abstract: In a delivery safety apparatus for a sheet-fed printing press, regardless of the operation mode of the delivery table (1) lifting unit, a delivery table is automatically moved downward on the basis of a detection result from a pile height detecting means for detecting a sheet pile height exceeding a predetermined position for sheets delivered and stacked on the delivery table. If automatic descending of the delivery table is not started even when a predetermined period of time has elapsed, this abnormal state is detected, and an alarm is generated. When automatic descending is not yet started when another predetermined period of time has elapsed after the alarm is generated, this abnormal state is detected to interrupt delivery of sheets onto the delivery table.
