Abstract: A rotary die-cut apparatus (20), in which a die roll (30) cooperates with a resiliently covered anvil roll (32) for die-cutting carton blanks passed therebetween, incorporates a constant mesh gear train between the die roll (30) and the anvil roll (32) for providing an infinite hunting ratio between these rolls. This provides more uniform wear of the anvil roll cover (42) and prolongs its effective life. Preferably, this gear train includes a harmonic drive (120, 130, 124) having a wave generator cam (124) rotatable by a trim motor (72). An arrangement (74; 78) for sensing changes in diameter of the anvil roll (32) due to wear of its cover (42) may provide an input for determining the speed of the trim motor (72). A resurfacing mechanism (86, 90) for removing the outer surface of the cover (42) when worn may provide this input. A pulse generator (250) is preferably incorporated in a controller (200) of the trim motor (72) for periodically making random changes in the speed of the trim motor. The gear train, with or without the trim motor, preferably has a gear ratio through multiple pairs of gears (62,96; 98,112;120,132;138,142) which itself provides an infinite hunting ratio. A gear (142) on the anvil roll (32) concentric therewith may mesh inside an internally toothed ring gear (138), these gears remaining in mesh when the anvil roll (32) is moved about an eccentric axis (156) towards or away from the die roll (30). An electric register (70) for registering the die roll (30) may be interconnected with the trim motor (72) for rotation of the anvil roll (32) with the die roll (30) when the apparatus is stopped.

Abstract: Digital data networks (such as the ISDN) which provide transmission between selected locations may use time multiplexed slots with predetermined maximum bit-rates. However local area networks (LANs) transmit packets, containing data bits, at a rate which varies frequently and often corresponds to a higher bit-rate than can be handled by individual slots. In the present invention packets arriving at a port 15 are allocated to queues 174 to 178 each for a respective destination, and each queue is allocated a group of slots on a digital data network. The slot contents are assembled into frames in a buffer 172 and transmitted by way of a terminal 11 to the digital network. On reception, the contents of several frames of incoming multiplexed slots are held in a frame store182 and then assembled into packets in buffers 184 to 188 making allowance for arrival in a different slot order and different frames. Marker signals are sent periodically in each slot and these signals are used to specify the order in which the slots were transmitted and to signal when the number of slots in each group is to change to allow for variations in packet traffic.

Abstract: A processing circuit for a digital camera system enables capture of a visual event which falls within some user-defined range. A digital camera con­verts a target image into a set of digital data signals, each signal representing the brightness level of a pixel in a matrix. A memory stores a mask also comprising a matrix of pixels. As the digital camera scans the target image, each data pixel from the camera is com­pared to a corresponding pixel in the mask and differ­ences in brightness between the two are counted. When the count reaches some predetermined value, the current frame of video data is saved for further analysis and/or display.

Abstract: An improved moulding press is described for moulding rubber articles or like materials, in which the curing temperature is reached at the inside of the mould by absorption of electromagnetic waves, in particular microwaves and radio-frequency waves. For an efficient emission and propagation of these waves within the mould, at least a portion of the impression surface is formed of a dielectric material having low losses with respect to the said waves. According to a first embodiment there is provided, between the two halves of the mould, a central electrode surrounded by the above-mentioned dielectric material and being formed of the same ferromagnetic material of the mould for propagating waves in the whole cavity between the two halves. According to a second embodiment the two parts of the mould, when closed, define a cavity filled with dielectric material which forms and constitutes the mould impression, wherein a probe is arranged for an electromagnetic excitation of the cavity.

Abstract: An induction plasma system comprises a torch (10) and an induction coil (14). A sample substance is injected into the plasma at an axial position that is adjustable while the plasma is being energized. The plasma-forming gas flows through the induction coil prior to passing through the plasma torch. A piezoelectric crystal (98) is used for initiating the plasma. An osciallator network generates radio frequency power at a first frequency, and an output LC network (206) that includes the induction coil is tuned to a second frequency higher than the first frequency. Means for maintaining constant power to the plasma includes an AC circuit for duty cycling AC power input to a DC power supply in response to a feedback signal relative to the rectified voltage. Thus a change in the rectified voltage effects an inverse change in the duty cycling such as to nullify the change in the rectified voltage.

Abstract: A data processing system is disclosed in which a plurality of central processing units have access to all the system resources, i.e., have a peer relationship. During initialization of the data processing system, all the system resources are allocated to the individual central processing units according to a preselected distribution, the identification of available resources thereafter being stored in the files of the individual central processing units. During the operation of the data processing system, the resources can be reallocated by a predetermined procedure. The central processing units entering such a relationship are required to include apparatus and/or software procedures that prevent access to system resources not assigned thereto. A mail box procedure, using locations in the main memory unit permit communication between the central processing units and are used in the dynamic allocation of resources.

Abstract: An asynchronous interface for coupling data between a terminal (136) and a data module is provided. The asynchronous interface directly determines and matches to the rate of serial data being transmitted by the terminal and received by the data module with minimal involvement of a processor (130) associated with the data module. The asynchronous interface determines the rate of the data being transmitted by configuring counting circuitry (200) therein for measuring the period of the start bit in the first received character whenever the speed of data being transmitted by the terminal must be determined. The asynchronous interface then adjusts to the newly determined data rate and receives the remaining bits in the first character and subsequent characters at the new rate. The processor is involved only to request that the asynchronous interface determine the incoming data rate and match to it and, once the data rate has been determined and matched, to process the recovered characters and this new rate. While the asynchronous interface determines and matches to the incoming data rate, the processor is freed for other tasks.
