Title: Data transmission standards conversion
Inventor: STEINER H
IPC: H04L12/52
Filed: 1980-09-24
Abstract: A circuit arrangement is provided for the transmission of digital signals between transmitting and/or receiving stations which operate with differing data transmission procedures and with different data formats. The signal transmission respectively occurs by way of a converter unit which, like the transmitting and receiving installations, is connected to a switching system. In the train of the transmission of digital signals from a transmitting installation operating with a lower data transmission rate to a receiving installation operating with a higher data transmission rate, the digital signals emitted by the appertaining transmitting installation are first collected in the converter unit in order to be emitted to the appertaining receiving installation only given the existence of a sufficient plurality of such signals. The transmission of digital signals from a transmitting installation operating with a higher data transmission rate to a receiving installation operating with a lower transmission rate occurs in data blocks. A respective plurality of data signals forming a block or, respectively, a signal group, is emitted together with a signal group end mark by the appertaining transmitting installation to the converter unit which then relays the digital signals to the appertaining receiving installation. In order to minimize control expense, the converter unit checks its signal acceptance capability upon the occurrence of the group end mark. Only given existence of a sufficient signal acceptance capability in the converter unit is an acknowledgment character emitted to the transmitting installation, the acknowledgment character then causing the transmission of signals forming a further signal group or block. The invention is preferably employed for signal transmission between telex stations and office printergram or teletex stations.

Title: Method and apparatus for drilling hard material
Inventor: MASSE ROGER
IPC: E21D9/10
Filed: 1985-03-05
Abstract: A hole is drilled in a front (9) of hard material, such as rock, by fragmenting the hard material with impact hammers (13a) along a plurality of spaced-apart paths extending in parallel planes (P1, P2,P3), each of which extends in a plane different from the planes in which the adjacent paths extend. The hammers (13a) are mounted in parallel, spaced-apart relationship on a support (15), each hammer having a head (17) spaced from the support (15) by a different distance from the adjacent hammer heads. The hammers (13a) are driven towards the front (9) by a motorized vehicle (5), and are simultaneously reciprocated in a plane parallel to the front (9) The fragmentation by impact along the paths causes simultaneous fragmentation by shear between the paths.

Title: Process of removing ions from solutions using a complex with sulfur-containing hydrocarbons
Inventor: BRUENING RONALD L
IPC: B01J20/10
Filed: 1993-06-08
Abstract: A method for the removal and concentration of desired ions such as Pd(II), Ru(III), Pd(IV), Au(III), Au(I), Ag(I), and Hg(II) from a multiple ion source solution which may contain larger concentrations of other undesired ions including H+ comprises bringing the source solution into contact with a compound comprising a sulfur and electron withdrawing group containing ligand covalently bonded through an organic spacer silicon grouping to a solid inorganic support. The sulfur and electron withdrawing group containing ligand portion(s) of the compound has an affinity for the desired ions to form a complex thereby removing the desired ions from the source solution. The desired ions are removed from the compound by contacting the compound with a much smaller volume of a receiving solution having a greater affinity for the desired ions than does the sulfur and electron withdrawing group containing ligand portion of the compound. The process is useful in removing desired or unwanted ions from acidic waste streams, metal refining streams, and other industrial or environmental streams. The invention is also drawn to the sulfur and electron withdrawing group containing ligands covalently bonded through a spacer grouping to a hydrophilic inorganic solid support material.

Abstract: A communication technique enables the efficient transmission of data through a communication link having a large delay bandwidth product and/or a high bit error rate. The communication technique multiplexes data from one or more data sources through a plurality of communication connections to increase the overall throughput and to reduce the average data transfer delay of the communication link. Each communication connection has a set of communication connection parameters that may be uniquely configured so that each connection carries a particular type of data at a particular effective priority level. Each communication connection may be uniquely configured to have a particular sending buffer size, to deliver messages having a particular length to an underlying layer and to send the messages into the link at a particular rate to orchestrate the manner in which the communication connections send data through the link.

Title: Arrangements for data timing recovery from distorted signals for use in adaptive modems with multi-level coding
IPC: H04L25/03
Filed: 1980-09-04
Granted: 1983-06-22
Abstract: The submission makes use of the fact that where an adaptive equaliser (APS) is incorporated in a modem, some sort of training sequence is employed prior to the transmission of the data message. This training sequence usually incorporates a block of pseudo-random data (DIS) transmitted at the basic symbol rate to provide the equaliser (APS) with a relatively less distorted signal to operate on. During the training period both threshold-derived timing (TCTRL) and Nyquist-derived timing (NTRL) are produced. The Nyquist-derived timing (NTRL) is then phase-shifted (APS) to correspond to the threshold derived timing (TCTRL) which is valid during the training period. The phase shift (APS) is then fixed so that, when multi-level coding is introduced valid timing can still be obtained from the Nyquist-derived timing signal (NTRL). In addition in the event of transmission interruptions the invention allows timing recovery without the need for a new training cycle.

Title: Casting mould
IPC: B22D11/04
Filed: 1980-11-22
Granted: 1984-08-01
Abstract: In a casting mould and cooling unit for use in the continuous casting of molten metal, the layers of lubricious, non-wetting material such as graphite (12) bounding the solidification chamber (10) of the mould are secured to the copper cooling jacket walls (14) through the agency of interfitting ribs and grooves (18,20) and a layer (22) of bonding material so as to afford good thermal conduction between the layers (12) and walls (14) even if a gap develops at the interface. The interfitting ribs and grooves are so shaped that each wall (14) and the corresponding layer (12) can be assembled by bringing them together facewise on. At least some of the grooves (20) are of re-entrant form to provide a mechanical key so as to reduce the possibility of a gap developing at the interface.

Patent GB-2272549-B (GB)
Title: Memory checkpointing
Inventor: COGHLAN BRIAN ARTHUR
IPC: G06F11/14
Filed: 1993-11-03
Granted: 1997-01-29
Abstract: A method for memory checkpointing which does not involve copying of data and that is virtually instantaneous involves designating the active location at a checkpoint as being the backup for the checkpoint. Until there is a new write operation after the checkpoint, this location is regarded as both the active and the backup location. At the first write operation after the checkpoint, the write is carried out to the other, previously non-designated location. Control of writing and indicating of the status of the locations is carried out by updating two binary bits for each pair of locations, namely, a first modification indicator bit and a second role indicator bit. The modification bits are stored on a resettable RAM for almost instantaneous checkpointing where the location granularity is that of a write operation. The method obviates the need for copying the contents of an active location at a checkpoint.
