Abstract: In a method for manufacturing grinding devices (26) using a mould (1), in which method the grinding compound (24) consists of a binding agent mixed with abrasive grains (27), the profiled surface (18) of the casting chamber (9, 10) has an open structure. Thus the abrasive grains (27) adjacent to the profiled surface (18) assume a random position after the solidifying in the binding agent, their sharp corners and edges preferably being orientated at right angles to the grinding surface. The grinding device (26) is thus immediately ready for use without the uppermost layer first having to be removed by dressing. <IMAGE>

Abstract: The  car L and  car M genes of  Streptomyces thermotolerams  have been isolated and used to construct recombinant DNA expression vectors. The  car L and  car M encode activities required for the biosynthesis of macrolide antibiotics. These genes have been shown to complement  Streptomyces fradiae  mutants which lack the ability to produce the antibiotic, tylosin. The  car L and  car M genes can be used not only to construct recombinant cells with increased ability to produce macrolides but also to construct recombinant cells with the ability to produce novel antibiotic compounds.

Abstract: A pattern injector for testing stations in a data communications network and the physical link between them. The pattern injector replaces normal characters in a normal, unmodified stream with injection characters. The pattern injector includes a multiplexor that receives both a current normal character and the injection character as inputs and provides the injection character as its output upon receipt of a select signal. Selection logic responsive to mode selection inputs selectively provides the select signal to the multiplexor in response to the various programmable pattern injector modes. In the Off mode, no replacement of normal characters occurs. In the One-Shot mode, the n th  normal character after detection of a preselected normal character in the unmodified stream is replaced with the injection character. In the Periodic mode, every n th  normal character in the unmodified stream is replaced with the injection character. In the Continuous mode, all normal characters in the unmodified stream are replaced with the injection character.

Abstract: Two sets of binary data of N bits in length are compared by first forming the exclusive OR function of each of the corresponding bits of the two data sets. The output of each of the exclusive OR gates controls two sets of transmission gates in each of N comparator circuits which are combined in series. If an individual pair of bits are the same, then the comparator circuit transfers the data from its compare input to its compare output, and if the individual bits are different, the the respective compare circuit transfers the data from the respective bit on one of the buses to the compare output of the circuit. The compare input of the first compare circuit is connected to ground and the compare input of the rest of the comparator circuits is connected to the compare output of the previous circuit and the compare output of the Nth compare circuit forms a signal indicative of whether the data on the first bus is greater than the data on the second bus.

Abstract: A mesh connected local area network provides automatic packet switching and routing between host computers coupled to the network. The network has a multiplicity of cut-through, nonblocking switches, each capable of simultaneously routing a multiplicity of data packets. Low host-to-host latency is achieved through the use of cut-through switches with separate internal buffers for each packet being routed. The switches are interconnected with one another and are coupled to the host computers of the network by point to point full duplex links. While each switch can be coupled to ten or more network members, i.e., switches and hosts, each link is coupled to only two network members and is dedicated to carrying signals therebetween. Whenever a new switch or link is added to the network, and whenever a switch or link fails, the switches in the network automatically reconfigure the network by recomputing the set of legal paths through the network.

Abstract: A first phase locked loop (12) generates a first timing signal (on 17) at a first horizontal synchronizing frequency (1f H ) corresponding to a horizontal synchronizing component (on 13) in a video signal (on 11). A converter circuit (56) derives from the first timing signal (on 17) a second timing signal (on 61), having a second frequency (2f H ) at a multiple of the first frequency and subject to a variation in frequency at a rate corresponding to the first frequency. A second phase locked loop (62) receives the second timing signal (on 61), which can be asymmetric within the period of the first timing signal (on 17), and a feedback signal (on 73) in accordance with the second frequency, and includes a controllable oscillator (66) for generating a smooth horizontal synchronizing signal (on 67) at the second frequency. The second phase locked loop has a characteristic loop response, determined by a low pass filter (63), preventing the voltage controlled oscillator (66) from changing frequency as fast as the rate of variation of the second timing signal (on 61). This drives the error signal for the controllable oscillator (66) toward an average value, resulting in a corrected, symmetric synchronizing signal at the second frequency. A horizontal output deflection stage (68) may be coupled to the second phase locked loop (62) for synchronized horizontal scanning in accordance with the second frequency. No additional signal processing circuitry is needed to correct the symmetry of the first timing signal generated by the first phase locked loop or the symmetry of the second timing signal derived by the converter.
